Museums are nowadays among the most popular projects for the public, the concept of thermal comfort in museums is often treated after the realization. Even if in the design, the architect shows a particular intention to work with daylight which is considered for these projects as main, the architect often considers certain elements that have an influence on the energy balance of these projects such as: orientation, building materials. The museum route is the key to the success of any museum project, it is the space of the visitor, the space in which he is invaded by sensations. In this study, we will first evaluate the thermal comfort in the museum as a whole (building) and then through its route. The objective is to guide reflection in the design of the museum towards the route in order to reduce energy consumption. In order to carry out our study, some European museums were analysed by means of simulation, according to the thermal comfort of their designs for the most unfavourable conditions, then by a thermal analysis of the museum route according to the segmentation principle using the average radiant temperature. This method allowed us to bring out correspondences between the architectural form and the route. Finally, the segmentation method constitutes the basis of a new methodological approach called "thermal topology" based on the discontinuities of the temperatures in the route.
Architecture (Latin architectura, from the Greek ἀρχιτέκτων architekton "architect", from ἀρχι- "chief" and "creator") is both the process and the product of planning, designing, and constructing buildings or other structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art.

This project was an attempt to investigate the art museum as an specific building type as well as the issues involved in the design of spaces for contemporary art. As every architectonic object, art museums are deeply connected with the functions they must fulfil and must act on the user as a stimulus which requires a behaviour response.*
According to Michel Foucault museums are sites that have the curious property of being in relation with all other sites, but in such a way as to suspend, neutralize, or invert the set of relations that they happen to designate, mirror or reflect. The museum space is capable of juxtaposing in a single space several sites that are in themselves incompatible . Its space begins to function at full capacity when men arrive at a sort of absolute break with their traditional idea of time.
Designing a new museum requires a strong concept. An art museum should never be made as a neutral, weak thing. It should be made new and passionate. The museum space should create possibilities for the unpredictable. A space that is inspired, unconventional, unafraid of taking risks, humorous, provocative and spontaneous.
The new museum shouldn’t be there to train people how to answer but how to question. That what’s the new museum is for.

Since a museum has developed from the institution which is dedicated to selection, preservation and presentation of objects to the one willing to communicate, educate and extend the audience, the museum tourism has become really important branch of cultural tourism. There are many theoretical perspectives of how to build the image of a museum, how to develop its audience nowadays and many mechanisms of museum management which show this theory functioning very well practically. Still, when it comes to the region of ex Yugoslav countries, there are many heritage spots which are floating in the limbo of shifted ideologies that once where spaces of the ruler’s representation and magnification and today are more or less successfully being converted into particular museums. Museum of Yugoslavia in Belgrade, an institution still linked to Josip Broz Tito in public discourse due to its position and collection, is maybe the most illustrative example to research how, through complete image building, new mission and vision, new name, new interpretation of inherited collection and new setting development, one place of memory and political happenings is being converted to a contemporary museum. In this paper, all the challenges of the new museum audience and programs building will be followed on this quite unique example of the (re)construction of the Museum of Yugoslavia.
A design museum is a museum with a focus on product, industrial, graphic, fashion and architectural design. Many design museums were founded as museums for applied arts or decorative arts and started only in the late 20th century to collect design.
The first museum of this kind was the Victoria and Albert Museum in London. In Germany the first museum of decorative arts was the Deutsches-Gewerbe-Museum zu Berlin (now Kunstgewerbemuseum), founded in 1868 in Berlin.[1]
Also some museums of contemporary or modern art have important design collections, like the MoMA in New York, the Centre Pompidou in Paris. A special concept has been realised in the Pinakothek der Moderne in Munich, in which four independent museums cooperate, one of them being Die Neue Sammlung – the largest design museum in the world.
Today corporate museums like the Vitra Design Museum, Museo Alessi or Museo Kartell play an important role.

POPULAR ARCHITECTURE AMONG VERNACULAR AND ERUDITE CONTEXTS pedro fonseca jorge
Abstract: In our present and contemporary architectural context abstractionism as become the face of a theoretical crisis where words seem to be the main form of communicating visually incomprehensible shapes. Therefore we need to search for a more figurative architecture based upon our landscape's features, making it necessary to proceed to Typological researches about our built surroundings. Rural housing has been a forgotten research field, as people tend to pay more attention to dense fabrics, but that doesn't mean that heritage can't be found in rural contexts. In this way to study rural architecture is to include Types of architecture that may or may not include features from other cultures than their own. This paper will try to define the features that define these Types, according to the contexts of Vernacular architecture (when there are no more references than the culture where it is produced) and Popular Architecture (where Signs or Significances have been brought from different contexts, being them Vernacular, Popular or Erudite).

ABSTRACT
The notion of “Cultural heritage” is quite modern compared to other humanistic fields developed in the last century. Conservation as a science has emerged and took shape during international conventions and treaties in many places in Europe and developed various frameworks to recognize the heritage and its value but based on “Eurocentric bias” criteria. The fact of sharing universal values and common practices during the age of globalization had a significant impact on conservation actions in contexts utterly different from western societies and don’t share the same historical or cultural dimensions. Therefore, this study traces the history of the evolution of conservation in the west from two perspectives; the historical one and the developing methodologies, and the philosophies behind the main theories in conservation. Cultural heritage is a reflection of the identity of the society and its past; thus, this study outlines the development of conservation practices in Egypt within the international approaches in a chronological order to investigate the social response and the impact of the political and cultural influence of the cultural consciousness of the society and the conservation actions in the Egyptian context. Furthermore, to investigate the contribution of international charters in developing national policies in Egypt.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Transportation has always been the backbone of development. Transit-oriented development (TOD) has been theorized, piloted and expanded increasingly in the past few decades. In this regard, this paper investigates the relationship between urban development, the transportation process, and the required implementation guidelines within fast-urbanizing cities, such as Cairo. After reviewing different related sustainable development theories, the study investigates pioneering case studies that have applied TOD and provided adequate implementation frameworks. The authors then extract and compare a set of required policies. The current Egyptian development paradigm is then discussed in relation to these enabling policies, focusing on Greater Cairo Region, Egypt. The authors debate previous development plans, progress, and newly proposed ones, focusing on the transportation process as the means for development. The study concludes with a set of required guidelines to ensure the integration of transportation with land-use planning, thus ensuring a more prosperous and inclusive urban development.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
This study investigates how urban parks can contribute to helping cities become more sustainable through developing a set of criteria for the sustainable design of urban parks. Today, there is no example around the world where all the proposed sustainable design criteria are applied together in a specific urban park. In this context, this study aims to make a novel contribution by systematically reviewing the literature on the sustainable design of urban parks. In the light of research findings, this study contributes to the implementation of a comprehensive sustainable park design practice in our cities in the future. These design criteria may further serve as performance indicators to offer information and know-how to local authorities, practitioners, communities, and other actors in this field to help them assess their success levels and progress over time.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Rehabilitation projects are interventions that can lead to the transformation of the socio-spatial structure of obsolescent neighborhoods. The main intention of such projects is the creation and/or improvement of social interactions after physical and functional interventions. Urban Renewal Organization of Tehran (UROT) is tasked with identification of target obsolescent neighborhoods, preparation of neighborhood development plans and implementation of rehabilitation projects to improve the quality of space and stimulate social interactions. In this paper, three urban spaces in different scales (“micro” for neighborhoods, “meso” for local and “macro” for trans-local scales), designed and implemented by UROT, were selected as a case study. By designing and filling a questionnaire and after analyzing research findings, the effect of the scale of the urban project on different activities was evaluated based on the Gehl model. Overall, in the expanded model based on the scale of space, an inverse ratio between the scale of space and both optional selective and social activities has been revealed.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The COVID-19 lockdown period has highlighted the ability of housing to accommodate a comprehensive programme typical of the city and its public space. Housing units of under 60 m2 and in blocks of flats are the more vulnerable, as they have a higher percentage of non-community open spaces. That problem was analysed using a methodology based on psychological, urban planning and architectural indicators applied to two coastal cities in the Mediterranean area of southern Spain. The results highlight three aspects in this type of dwelling: the need to consider the orientation of the housing to improve the quality of indoor and outdoor space; the need in public housing policies for a greater number of rooms to facilitate remote working; and finally, the importance of functional terraces overlooking green areas.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Recently the effect of greenhouse gases (GHGs) is worldwide terrified anxiety to the public and scholars. Even this global problem is one of the great issues that continuously makes worrying the governments and environmentalists, but its solution findings are not out of the image at all. In this study, we have proposed and analysed a mathematical model for the solvable management of GHGs by sowing the seeds of green building dynamic systems. Moreover, in the model, the human community is used to enhance the production power of individuals of green buildings by absorbing the GHGs. The model is analysed by stability analysis at the equilibrium points: trivial and global equilibrium, and also by convincing the stability and instability of the system of equations. The behaviour of the propound model has been developed by numerical simulations which shows the rate of the fruitfulness of GHG components.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Afghanistan has suffered from four decades of war, causing a massive migration of the rural population to the cities. Kabul was originally designed for 1,5 million people, whereas there are now 5 million in the city. The importation of modern western styles housing for rapid reconstruction reveals apparent cultural conflict and a significant environmental footprint. The new drive for sustainable reconstruction should consider the use of local materials combined with modern technologies. Earthen architecture underlies the embodiment of Afghan architecture. This research aims to revisit traditional Afghan earthen construction with the tools of industrial modernity. The three soils of the Kabul region are first characterized. Sun-dried mud brick and compressive earth block, with and without stabilization have been prepared and tested in the laboratory to develop the most suitable earth construction element which is cost-effective and easily available compared to imported modern products.

Tourism is a major economic source for Egypt, due to its significant natural and cultural attractions. Yet, rapid development and construction of touristic facilities have a negative impact on the fragile natural and cultural heritage. This paper studies the recent touristic developments of the coastal stretch of Ain-Sukhna on the Red Sea coastal region of Galala Mountain, and their impact on the surrounding natural and cultural attractions. Coral reefs and rich marine life have made this stretch among the prime fishing and scuba diving destinations in the world. The area is also famous for its year-round sunny beaches and the spectacular coastal scenic drive where Galala Mountain reaches the Red Sea. Recently, development has started on the mountains following the construction of Galala Mountain Road. Galala City started with Galala University and several residential, touristic, and commercial facilities. This paper studies the pattern of development in the area during the past 40 years and assesses its impact on natural and cultural resources.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
Colombo, Sri Lanka’s commercial capital is a forceful creation of European colonialists who occupied the island for over four centuries. Its urban structure displays the social fragmentation sought by the rulers. Colombo elaborates an extraordinary process of city-making, stratified with its Dutch-origin, British-reshaping, and post-colonial adaptation. Proclaiming such a contested past as an inheritance requires an inclusive heritage interpretation. The recent renovation of monumental buildings for potential market values and demolishing minor architecture do not display such a heritage interpretation. This, placing undue attention on a selected social group, is found to be further emptying the compartmentalized city. The exclusion of some sub-societies also cost possible stewardship to urban heritage. Having observed the non-sustainability of current heritage-interpretation practised in Colombo, we searched for alternative means to unify societies in time-space thus sustaining the diversity of urban spaces. Our empirical studies have established the need to integrate the inherent cultural values of the colonial-built urban fabric in heritage interpretation. The results of vibrant heritage-interpretation results have been studied through a literature survey with aims to contribute towards the development of an inclusive heritage interpretation practice to protect Colombo’s colonial past sustainably.

ABSTRACT
Heritage admits diverse readings depending on different territorial spaces, contexts, and knowledge fields. The relation between Heritage and the social contexts is one of these knowledge areas. But Heritage accepts a dual perception as a cultural reflection. It may be considered either as the origins of the conflicts or the engine for recomposing disrupted territories. The paper proposes a reflection on the topics related to conflict territories and the roles currently played by Cultural Heritage. The recomposition of conflict territories is based on a continuous intercultural approach with important contributions from human rights, genders equality, intercultural dialogue perspectives and the fact of taking heritage as a territorial stabilization factor. The paper presents specific practical cases in the Eastern Mediterranean region where actions on Heritage religious elements collide with the national sovereign of the respective current countries. A comparative study among these different actions proves that the initial clashes can be progressively transformed into strategies able to become the future guideline for the resolution of heritage regional conflicts. These conflicts reflect two discourses: political (with strong links between national identity and religion) and scientific (with a clash between static concept and dynamic vision) where objects interact with the visitors.

ABSTRACT
Many studies have been conducted over the last 20 years to determine and measure factors that affect the walkability of city streets. Walkability is an essential factor in deciding whether a city is green or sustainable. This paper creates a comprehensive walkability index by analysing built environmental indicators that affect walkability. This research was conducted on mixed land use streets in Cairo, Egypt, combining the results from an online survey and a walkability assessment model developed by multi-criteria decision analysis techniques. The results were based on a three-pillar approach starting with the theoretical background to frame the walkability indicator, numerical assessment over the Egyptian cases using a multi-criteria decision-making (MCDM) technique and a qualitative user perception survey. Our results confirm that determining to what extent Cairo’s streets are walkable is crucial to enhancing pedestrians’ perceptions of the walking environment. Furthermore, the results illustrated the essential factors within the built environment indicators that influence pedestrian walking behaviour.

ABSTRACT
Since the 1960s, new town developments within large metropolises have been widely adopted to decongest the city centres, especially in Asian cities. This paper provides a brief account of the liveability dimensions of two new townships developed in large metropolitan areas: Senri New Town in Osaka and Purbachal New Town in Dhaka. The study primarily draws on master plans of the two developments to identify how the components of the plans reflect the physical, social, functional and safety dimensions of a proposed liveability framework. The methodology combines a review of masters plans with scholarly and grey literature on the two new town developments. The findings show while the social and functional dimensions are integrated with Senri New Town; Purbachal New Town, though more recent, appears to have missed opportunities for diversifying density, social mix and mass transit. The paper concludes that the comparative case, Senri-New Town provides insights on how public-private people participation can leverage citizen-centred design for more liveable residential living environments in developing cities.

ABSTRACT
Nowadays, uncontrolled urbanisation is one of the major problems facing Algerian oasis regions. The monitoring and evaluation of its landscape transformations remain a key step for any oasis sustainability project. This study highlights the evolution of spatial growth in the city of Adrar in southern Algeria during the period 1986-2016 by establishing a Spatio-temporal mapping and landscape quantification. The methodological approach is based on a multi-temporal analysis of Landsat satellite images for 1986, 1996, 2006 and 2016, and the application of landscape metrics. The results show two opposite spatial trends: significant growth of built-up areas against an excessive loss of palm groves. The landscape metrics allowed the identification of a progressive fragmentation process characterising the palm groves. Thus, the findings of this study show the utility of satellite imagery and landscape metrics approach for monitoring urbanisation patterns and assessing their impacts on oasis ecosystems.

Participation in decision-making processes foreshadows enabling citizens, communities, non-governmental organizations and other interested parties to influence the formulation of policies and laws affecting them. The purpose of this study is not only to review Lithuanian legal documents but also to analyse recent processes in Kaunas city planning. Kaunas city is undergoing various urban processes, which do not always meet the needs of the community. This study presents an analysis of the forms of community involvement in the urban planning processes and survey data on the effectiveness of community involvement. The methodology requires using a sociological survey with representatives of the city community and a comparative analysis between legal obligations and actual urbanization process.

Assessing the impact of urban morphology on the indoor thermal condition of housing in a tourism city in central Vietnam — Hoi An City is the main objective of this study. The research process is carried out by a variety of methods including in situ surveys, measuring with temperature sensors, data analysis and map analysis. Four houses, located in two areas with different urban forms, were selected for measurement within one month to investigate the differences in housing indoor temperature. The impact of urban morphology on housing was thereafter determined. Temperature sensors were permanently installed in 4 houses; based on these empirical measurements and data collected, the paper addresses solutions to improve urban morphology and indoor thermal condition.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The phenomenon of planning involving citizen’s participation in planning literature has been from the second half of the 20th century. Indeed, different methods and techniques have been used in the process. However, participatory practices are time-consuming and negotiations are tiresome. Accordingly, the integration of developing digital technologies into participatory processes has been seen as a potential to reach large audiences and provide time-space independence. Within the scope of this research, a detailed literature review was done regarding e-participation, and ten (10) examples representing the upper levels at the ladder of participation were examined within the context of the project, participation, and socio-technical criteria. SWOT analyzes were structured by grouping similar applications, and current trends for the use of e-participation in urban design have been revealed. The analysis showed that citizens e participation- participation tend to allow citizen design or location-based interaction, playful interfaces and game elements which can be sources for encouragement.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
For decades, numerous countries have been witnessing the Street Children phenomenon where millions of children worldwide are subjected to risks. Despite the crucial role of intermediate non-residential interventions - using drop-in centers- in protecting and rehabilitating street children, there is a paucity of research addressing the quality of design of these centers and how architecture might influence their operational process. Those observations invite investigating drop-in centers used in practice from a design perspective and question adapting architectural applications for humanitarian emergencies, focusing on “Child-Friendly Spaces”. The study aims to provide solutions for better quality design, facilitating operational challenges. The methodology undertakes the investigation through primary and secondary axes. This involves conducting literature and international precedents review and secondarily, an Egyptian contextual first-hand documentation and qualitative analysis of selected centers.

ABSTRACT
The present study argues that the urban form of affordable housing projects affects safety and security. The study examines the level of safety and security in the Prince Fawaz project proposing recommendations that enhance it. Theories and approaches concerned with the environmental crime are initially reviewed. Then, urban and architectural features as well as crime rates and patterns are documented. Also, trace and behaviour observations are carried out. The observations monitored urban features and behaviours associated with crime or fear of crime. Residents’ perception for security and fear of crime is extracted through a questionnaire. A Space Syntax is processed and linked with the questionnaire and observation outputs. Observations demonstrate a semblance of fear of crime which is supported by records of car and home theft. Although the questionnaire reflects a suitable level of security, it points to peripheral spaces and areas around mosques and shops as the less secure. However, enhancing security in the Prince Fawaz project requires urban interventions including controlling access to peripheral spaces, reviving areas detected to be unsafe, repositioning elements causing visual obstacles and enhancing appearance by vegetation and sustainable maintenance. Besides, reformulating the movement network so that an appropriate integration between residents and strangers is achieved. On the conceptual level, the study proves that none of the theories of environmental crime can act as a comprehensive approach; but each can partly work.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
The interaction between transport, land-uses and travel patterns produce diverse transportation problems in urban cities with traffic congestion as the most visible manifestation. Traffic congestion is a frequent phenomenon in most cities around the globe. This paper reviews the interaction between land-use traffic congestion through published literature. The objective of this study is to encourage and provide researchers with future research directions in land-use and traffic congestion. For this purpose, a systematic review was performed analysing 45 articles from the year 2010 to 2020 using a descriptive approach. Subsequently, the results of the study show that although the interaction between land-use and traffic congestion has gained currency in developed countries far less is known on this subject in developing parts of the world, though new evidence is steadily accumulating. Consequently, limitations of this work are presented, opportunities are identified for future lines of research. Finally, the conclusion confirms the need for further research addressing the methodological concerns.

ABSTRACT D:\My Journal\papers\Vol 4 ISSUE 1\1 senem sadri Turkey\check for updates2020ijcua.tif
“SIMURG_CITIES” is the research and development project that is developed under the main project named SIMURG: “A performance-based and Sustainability-oriented Integration Model Using Relational database architecture to increase Global competitiveness of Turkish construction industry in industry 5.0 era”, is a relational database model that is currently being developed in a dissertation for performance-based development and assessment of sustainable and sophisticated solutions for the built environment. This study aims to analyze the key performance indicators (KPIs) at «Cities Level» for the smart city concept that is referred to as «Layers» in the master project. KPIs for the concept of a smart city are determined by using the meta-analysis technique. Hence, the three most reputable urban journals issued from 2017 through 2020 are reviewed in this study. In addition to this, models of smart city frameworks/assessment tools/KPIs are reviewed within the context of this paper; environment, economy, and governance were found to have domain themes on urban sustainability according to the literature review. Consequently, efficient and integrated urban management, environmental monitoring and management, public and social services of urban development, and sustainability are found to be the most important dimensions in urban and regional planning. SIMURG_CITIES evaluation models for urban projects can use the findings of this paper.

Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.

Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

passed from the metric dimensional character
to the ambient psychological character.
Reflections on the human body have shown
that the body does not stop at the surface of
the skin, it has an immaterial boundary called
bubble that is located in close proximity to his
body. (J.Cousin, 1980)
Thus, it will be necessary to imagine that the
body is included in a bubble which is also
composed of several layers taking the form of
a protective eclamptic sphere. Man is thus
surrounded by several spheres of variable
dimensions; these variations are due to his way
of moving in space and the route between
several spaces. These variations affect human
man's behavior and his ways of appropriating
space. The requirements of the human being
as to his space are multiple, it can be noticed
that from our reading, there are three ways of
appropriating the space, a very personal way
making it private, a way slightly personal
making it semi-public, and a not personal way
making it public.
The house is currently considered as the private
space of the human being, many are the
research works that deal with its aspects,
however there are also projects that are
considered by the human being as private with
varying degrees of change such as offices, or
work offices or even schools, hospitals ... in our
era there are also many project intended for
the general public, we find shopping centers,
theaters, museums...
The museum has a public character because it
is designed and intended since the beginning
of its appearance to the public, however it also
has its private property and many
characteristics in relation to its user who is its
visitor. Visitors must be transported by their
emotions and live a very personal adventure in
a space intended for the public
2. Literature Review
2.1. The museums a "place" for the public:
Previously, the architecture of the museum,
directly inherited from the great princely
residences, had been adapted to become at
the same time the setting, the decoration of a
private collection; then a public, and place of
its ideal contemplation. The laws derived from
the theories of "Gestalt" have developed the
design of these spaces. They are not the only
ones, there are also the various studies carried
out in the company of visually impaired
people, which made it possible to establish
some rules in the perception of space. Certain
principles of the psychology of perception can
also find an application in architecture and
especially in museum architecture.
For a person who has all his senses, the
experience of architecture is primarily visual
(sense of movement). The movement of the
body, even if it is not one of our five senses,
offers us the measure of things and space. The
route, the visit, allow the appreciation of the
grandeur. We note that the exploration of a
space is carried out by simple gestures such as
approaching, moving away, going around,
going up, going down, penetrating, etc. These
actions invite us to control what we want to
see, hear, smell, taste, touch in a given
environment.
During an exhibition, the visitor perceives and
appropriates an ambience, and at the same
time, "dialogue" with what he sees, hears, or
touches, etc. It is no longer in a "space"
(quantifiable volume, whose physical
dimensions and surface can be determined), it
is located in a "place" that has a history and
that we will discover. The "place" is the result of
a state of mind, a feeling of well-being or
malaise, a feeling.
2.2. The design of contemporary museums:
In this paper we will focus on contemporary
museums, with an overview of the steps that
the museum has taken to reach its present
complete form, and finally, the relationship
between its external and internal aspect thanks
to the notion of the route.
2.2.1. An overview of the evolution of the
design:
The appearance of the museum design had
evolved, according to I. Bayón Juan (2013) in
the city of the 19th century, the museum was
consolidated as an important building in the
urban context with a social function, the
consolidation of several elaborate and defined
models generated new typological qualifiers i)
the Museum-temple, ii) the Museum-palace, ii)
the Composite Museum.
The great social and cultural transformations of
the 20th century changed the concept of the
museum, its social function and the way it was
exhibited. The museum will no longer be a
national sanctuary of art or science, but a tool
for the conservation and transmission of
knowledge. (I. B. Juan, 2013)
In the post-war period, a new type of museum
appeared, the museum as a “white cube” of
modernity, linked to the universal space of Mies
van der Rohe. The first reactions against the
white cube and the museum's association with
the mausoleum began to appear in the 1970s.

Van der Rohe's ideas for spaces have been
taken up by a new generation. The museum
had ceased to be a temple or a treasure
house, the best example of these new ideas
was the Centre Pompidou opened in 1977.
In the 21st century the museum surpasses all
others in its symbolic character. For this, the
architecture of the museum has become a
gigantic sculpture on a tray or a recognizable
silhouette tower. The most representative
museum of this new image of monumentality
and the media is the Guggenheim in Bilbao. (I.
B. Juan, 2013)
The design of the museum went through four
main stages: i) The collection of objects as a
sacred act: one rarely exposed to the public
that during the festivals according to the
period and the dominant religious belief of the
time, it was practiced at temples, churches,
While the collections were in the hands of the
church, exposed in temples and cloisters, there
was no need to create special spaces for
them, ii) Presentation to the public: Everything
changed when collectivism became secular
and began to be exercised by princes and
nobles. This is how the need to develop new
types of spaces to preserve and exhibit is born.
this period of visual design appears according
to the historical chronology: the studios of the
Renaissance princes, the palaces of Belvedere,
the galleries ,The creation of object cabinets,
iii) as varied function : Baroque art brought a
flourishing of the art by encouraging the
spaces of exhibition for a better valorization of
the collections, it is at this time that one
conceived the first architecture for the
conservation and the exhibition of the
collections, The museum opened in 1683, and
had to wait until the 19th century so that the
operation of removal of the collections can be
carried outiv) varied design: according to the
content, the architectural form and the current
of the architect; according to the routes,... (I. B.
Juan, 2013)
In the contemporary museum the concept of
the route is the key element of the design of
the museum since its appearance, we will now
see how it is treated in the museum.
2.2.2. An interior design and the notion of the
route:
Le Corbusier (1977) had highlighted the fact
that architecture is a journey, with its concept
of "architectural walk". If villas, religious
buildings, etc., offer architectural walks, it is
obviously the museums that are the clearest
examples. Jean-Raphaël Pigeon (2013) notes
that it is only possible for man to visualize
himself in his route if he becomes aware of his
environment through his body, this awareness
allows a better understanding of architectural
space. The first relationships between man and
the route refer to visual abilities, man tends to
understand the environment in which he finds
himself and appropriate it through decoding
information that space sends him.
J-R-Pigeon (2013) evokes the works of J Cousin,
the use of the bubble by the latter can better
define the relations between man and his
space and beyond the route, the bubble is
much more than a series of layers extending on
the periphery of the human body. It does not
have fixed dimensions or a particular shape,
but changes in the spatial route according to
the movements of the body, it marries the
body at a certain distance, but can expand,
widen, or also compress itself according to the
context. The location of the components of the
architectural route (such as transition and
intermediate spaces) have a particular
importance and influence on the users of the
route. However, the direction taken in the user's
route, through the spaces, influences the
perception of the latter.
The concept of route is not easy to define,
because of its polysemy. We can adopt, for
example, the definition of LAROUSSE (2009, p.
356): "it is the route or route followed to go from
one point to another". Common sense gives
various meanings. Showing the complexity of
this term: (path, circuit, route, triathlon, course,
crossing, stage, etc.). For some researchers, the
route represents the movement of the body in
space. For others, it is described as a design-
visit interaction, the route being taken into
account according to the context. With the
route, the simple act of moving begins to make
sense.
Many solutions to traffic principles have been
developed; they fall into three categories
according to their form (Mariani. R, 2000). (i)
The "linear" route: an obligatory scheme, (ii) The
"labyrinth" route: no traffic constraints, (iii) The
"centered" route: The public is free to choose
the route of its visit.
This typology proposed by Mariani. R (2000), is
very complete if we associate it with the one
proposed by Jean Davallon linked to the three
levels of exhibition: i) the conception (thought
route), ii) the setting in exhibition (proposed
route), iii) and the visit (lived route).
However, this typology proves insufficient if we
compare it to the work carried out by A. Borie
and al (1985) and P. Panerai and al (1983), we
have noticed for the same typology several
other sub-typologies are associated, and after
a reading of the two proposed typologies we

summarized them as follows (Table 1):
Table 1. Different route configurations.
2.3. The notion of comfort in the museum and
thermal comfort:
If we take the research carried out on
museums from the angle of comfort, we will
realize that the first aspect of comfort that
researchers deal with is visual comfort, this is
due to the initial function of the museum, which
is the exhibition of works of art, if the visitor is
there it is to visually appreciate the exhibition.
The element of ambience linked to the visual
comfort that is often treated in museums is the
light, it is studied not for the comfort of the user
and the success of the exhibition but also its
influence on the works of art (deterioration).
However, despite the importance of light and
visual comfort, there is also another type of
comfort that can influence the success of the
exposure is thermal comfort. This comfort is
linked to the thermal environment often very
much influenced by the architect's choices
during the design with regard to the choice of
materials... it is mainly linked to the conditions
of temperature, humidity and wind as the users
are exposed, but it also concerns the works of
art and their lives, since in the museum it will be
necessary to maintain a precise temperature
and relative humidity for the maintenance of
the works. It is very important to specify that the
thermal performance will say as much about
the energy performance, generally expressed
in kilowatt-hours of primary energy consumed
for 1 m² and over a year (KWh-ep/m².an), the
energy performance of a building designates
its ability to limit energy consumption within a
project, taking into account the quality of its
heating equipment, but perhaps above all, its
thermal behavior. The latter refers to the
evolution of temperatures inside the building.
(H.T Minassian, 2014)
Returning to thermal comfort, and starting with
the users, the first essential condition to provide
thermal comfort to a person is to balance his
energy balance. The calorific power produced
by the metabolism must be equal to the power
dissipated in the environment by the five
exchange means. (M. Le Guay,2009) Thermal
comfort is linked to energy performance, we
are now seeking to make energy performance
5. JOURNAL OF CONTEMPORARY URBAN AFFAIRS, 2(3), 122-136 / 2018
Selma SARAOUI, Azeddine Belakehal, Abdelghani ATTAR, Amar BENNADJI 126
optimal, and it is by improving thermal comfort
that this will be done.
Research in the thermal field concerning the
museum without very rare and since we are
interested in contemporary space we quote
the work of Philippe Rahm (2005) in which he
speaks of the birth of a new thermal approach
with the free plane of Le Corbusier, he begins
from the observation that the way of heating a
space passes by heating each sub-space
separately, and therefore he proposes with the
same principle of the free plan or everything
communicates to try to think of the whole
house as a global atmosphere, this led to the
birth of a new concept which is the thermal
landscape.
Philippe Rahm had first of all tried to found a
new architectural language linked to the
thermal aspects and inspired by the values of
the invisible. He then adopted the concept of
the Gulf stream which is based on: i) the
creation of an invisible, complex and rich
thermal landscape, defined according to
multiple zones of different temperatures as
many climates, sensitivities, territories, ii) In this
architectural design process, an atmosphere is
created first, before the program, before the
spatial forms, iii) It is then that the program is
placed in space, looking for sensual thermal
conveniences that cross localized ambient
temperature criteria, clothing, physical activity.
(P. Rahm, 2014)
In the case of museums, we can mention his
work on the THERMAL DISTORSION for the
Contemporary Art Gallery in Grand Palais
(Paris, 2009), which first takes place through the
zoning of activities, defining space by nuance
of heat that generates different zones and
functions (Working seated: 21°C, visiting
walking: 16°C, Storing: 12°C). He therefore
established from these needs a design
according to the temperatures of the space to
be designed.
Rahm's work is more than interesting insofar as
he begins to analyze before designing and
according to that he designs. The observation
made on the case of European museums is
that the thermal comfort component is often
linked to the construction phase, the architect
chooses the materials, proposes a particular
orientation of the projects and the interior
spaces, sometimes use software for the
calculation and estimation of the energy
balances related to the heat of his building,
except that the real heating and air-
conditioning powers to install his estimate once
the project is completed.
In the case of museum projects realized with a
particular architectural form, is there a
relationship between the chosen form and
thermal comfort for the most unfavorable
conditions (daily and seasonal? and how does
the choice of the course participate to make
the thermal comfort during the visit better?
Can better thermal comfort conditions be
expected from the project design phase?
3. Methodology and case study
3.1. Methodology
The element that we will use to evaluate the
thermal comfort in this paper is the mean
radiant temperature (MRT). This last represents
from a theoretical point of view one of the
elements with major influence on the comfort,
it is the average of the surface temperatures of
the walls which surround the person, it allows to
give an idea on the resulting temperature of
the comfort which is calculated by the relation:
Resulting temperature ≈ (Ambient + mean
radiant temperature) / 2
3.1.1. Evaluation of the comfort of the building:
We first calculate the different coefficients of
form, of compactness and the ratio surface loss
/ living area in order to obtain information on
the thermal capacities of each architectural
volume.
We modelled after reduced models of our
case studies with their real dimensions, their
climatic files and all the characteristics of the
construction materials and the context. We
then simulated the thermal comfort as a
function of the mean radiant temperature
using the Ecotect 05 software, the simulation
was carried out in several stages as follows:
The plan views of the analysis grids for
the critical hours of the most
unfavorable day according to the
season, we obtained 6 representative
results by plan views. In this regard, we
cite the case of the first floor of the
Acropolis Museum in Athens (Table 2).
6. JOURNAL OF CONTEMPORARY URBAN AFFAIRS, 2(3), 122-136 / 2018
Selma SARAOUI, Azeddine Belakehal, Abdelghani ATTAR, Amar BENNADJI 127
Table 2. Variation of the mean radiant temperature in the
Museum of the Acropolis of Athens
We determined the recommended
radiant temperature and compared it
with the simulation results to obtain the
percentages of the temperatures in the
interior building spaces that respect this
temperature.
The correspondence between the different
case studies allowed us to make a first reading.
3.1.2. Assessment of thermal comfort in the
museum route:
We then took the schematic results of the
resulting mean radiant temperatures and on
these we drawn the route, considering each
colored part of the plan with a temperature as
segments a part, we calculated the number of
segments for each temperature and from this
calculation we determined the temperature
Figure 1: Schematic segmentation, and graph of number
of segments by temperature (source: author, 2018)
3.1.3. The correspondence between the two
methods of analysis:
It is by means of the Statistical 07 software that
we will proceed to carry out correspondences
between the various parameters analyzed by
means of a multivariate analysis. All
methodology had been explained in Figure 02.

Selma SARAOUI, Azeddine Belakehal, Abdelghani ATTAR, Amar BENNADJI 128
Figure 2: Methodological principle (source: author, 2018)
3.2. Case studies:
We have chosen our case studies according to
a selection criteria grid, and we quote to this
effect.
3.2.1. Architecture and architectural form: It
should be noted that the selected museums all
belong to the same historical period (1980-
2008), museums where the architect had tried
to display a particular intention to work with the
daylight given the function of exposure
(orientation, materials, daylight,) which will
have a particular influence on thermal
comfort. For the plan shape based on the
optimum which varies according to the
latitude of place. Our museums are all located
on latitudes between (37°N_59°N) and altitudes
which vary between 0 and 300m.
3.2.2. Geometry, shape and compactness
coefficients: The size and geometry of the
building partly determine the heating and
cooling requirements. We have therefore
classified our selected cases according to their
shape coefficient, representing the ratio
between the surface of the envelope and the
habitable volume (m²/m3), it indicates the
degree of exposure of the building to climatic
factors, it is a very important criterion in the
thermal evaluation of the building but delicate
to apply because it depends on several
factors, such as the geometric shape, the size
and the mode of contact of the buildings.
(Roger Camous et al, 1979).
3.2.3. The orientation: The southern exposure is
interesting because the sun is high and it is easy
to protect oneself. It is the most favorable
exposure in summer after full north, while being
the best in winter. For that we chose museums
oriented South or South-East or South-West.
So, we have proposed, according to the
architectural form and in relation to thermal
comfort, 09 museums presented in the table 3:

4. Results and discussion:
4.1. Evaluation of the comfort of the building: In
relation to the coefficients
For the coefficient of compactness, we found
very varied results, the Bilbao Museum presents
the lowest coefficients (0,11) compared to the
proposed museum, however the Jewish
Museum of Berlin and the Hergé Museum and
the Maxxi and the Acropolis Museum Athens
have a coefficient in the same interval (0,15
and 0.25). The prehistoric departmental
museums, the Beyeler Riehen and centro
Gallego de Arte contemporary have
practically the same coefficients (0, 5).
In the case of the ratio of loss area to living
area, we did not find any relationship between
the results obtained for the different case
studies. We go from 0,5 for the case of Bilbao to
1,2 for the Museum of Hergé, 1,8 for the Jewish
Museum, the Museum of the Acropolis Athens,
the Beyeler Riehen between 2 and 2,3 .and
finally the great values for the Prehistoric
Departmental Museum and centro Gallego de
Arte contemporary ≤ 3.
These coefficients do not give us a plausible
reading of the thermal quality of buildings, the
most interesting from a scientific point of view is
the ratio surface loss / living area, but for our
study cases there is a variation between the
floor area and the footprint which makes the
relationship between the results very subjective.
However by the coefficients of form we can
already classify our museums into three formal
categories: i) museum of simple form (Cf≈2):
Prehistoric departmental museum, the Centro
Gallego de Rate contemporaneo and the
Beyeler Riehen, ii) Museums of simple form
modified to 50% (see ≈ 4 to 5): the Jewish
Museum of Berlin, the Hergé Museum and the
Museum of the Acropolis Athens. And finally,
the museum with complex form (Cf: 6,3): the
museums Guggenheim Museum Bilbao, DE
MAXXI and Grenoble Museum of Fine Arts.
4.1.1. The percentage of annual thermal
comfort and the respect of the MTR:
After the simulation we obtained the
percentage of the overall comfort (Table 4) of
the building and we can say that for all
museums there is no particular relationship
being the results all museums achieve almost
50% percentage of comfort.
10. JOURNAL OF CONTEMPORARY URBAN AFFAIRS, 2(3), 122-136 / 2018
Selma SARAOUI, Azeddine Belakehal, Abdelghani ATTAR, Amar BENNADJI 131
Table 4. Annual thermal comfort and the MTR
For the unfavorable period of the winter, for
museums whose coefficient of form is around 2,
the percentage of the mean radiant
temperature in the global building for the
winter period is respected with a percentage
less than 50%, such as the case of museums:
prehistoric departmental, the Museum Beyeler
Riehen and Centro Gallego de Arte
contemporaneo, (Figure 03) for museums
whose coefficient is equal to 5, the percentage
of the respect of the mean radiant
temperature is higher than 50% we quote the
example of the Museum of the Acropolis
Athens, and for the museums or the
coefficients is higher than 6 the percentages
approaches 50%.
For the unfavorable period in mid-season, there
is no variation for the percentage of mean
radiant temperature, in all museums it is greater
than 50%.
For the most unfavorable period of the summer,
we notice a percentage exceeding 50% for
museums where the coefficient of form is equal
11. JOURNAL OF CONTEMPORARY URBAN AFFAIRS, 2(3), 122-136 / 2018
Selma SARAOUI, Azeddine Belakehal, Abdelghani ATTAR, Amar BENNADJI 132
to 2 such as the case of the Centro Gallego de
Arte contemporaneo, for the rest of the cases it
is considered as average approaching 50%.
This reading does not offer any particular
information with regard to the notion of
comfort from conception, and despite the
disparities that may exist, it does not present
any particularity of thermal point specific to the
museums in the corpus of study.

4.2. Assessment of thermal comfort in the
museum route:
4.2.1. Differences in mean radiant temperature
in winter:
The differences of mean radiant temperature
are present within the route of two museums of
case studies which are: Museum of the
Acropolis Athens, and the Prehistoric
Departmental Museum. (Figure 04) These
differences characterize the three periods of
the day when we passed for example in the
case of the Acropolis Museum from 03
segments of 05° and 02 segments of 09° in the
morning of the coldest day to 04 segments of
05° and 03 segments of 09° at noon, and 05
segments of 05° and 06 segments of 09°. The
correspondence also shows the total absence
in these cases of a study of radiant mean
temperature differences for the summer period.
Figure 4: Diagram of variation in number of temperature
segments, daily and seasonal variations
If we return to the initial segmentation of the
route according to temperatures, we will
notice that for these two cases (Figure 05) the
visit begins from the same point and also ends
in the same point, the route is considered linear
for the visit but from a conceptual point of view
it is rectilinear centered.
Figure 5: the route plan for the case of Prehistoric
Departmental Museum and Museum of the Acropolis
4.2.2. Differences mean radiant temperature in
summer:
These types of Differences characterize three
museums of our case studies which are the
Beyeler Riehen Museum, The Centro Gallego
de Arte contemporaneo and the Hergé
Museum, with a total absence of temperature
differences during the winter period (Figure 06).
We cite the case of the Beyeler Riehen
museum, where we notice according to the
graph that for the morning of the hottest day
the route consists of 03 segments, a first one
with a mean radiant temperature of 18°, and
12. JOURNAL OF CONTEMPORARY URBAN AFFAIRS, 2(3), 122-136 / 2018
Selma SARAOUI, Azeddine Belakehal, Abdelghani ATTAR, Amar BENNADJI 133
02 segments where the temperature is 22°, at
noon for the same day the route will have 03
temperatures, 18° on a segment, 22° on 10
segments, and finally 30° on 07 segments. For
the afternoon of the hottest period we will
have 02 segments of 18°, and one at 22°.
Figure 06: Diagram of variation in number of temperature
segments, daily and seasonal variations
The route for these three case studies is of the
same nature as it appears in the Figure 07, it is
considered linear for the visitor, from the
conceptual point of view, the linearity of this
route can be in the case of the Museum
Beyeler Riehen segmented, the Centro Gallego
de Arte contemporary adopt the form of a
zigzag and finally the Museum Hergé be
labyrinthine in nature.
Figure 07: the route plan
4.2.3. Differences in the mean radiant
temperature in mid-season:
These differences are the most important for
our study cases, given the fact that they can
extend over a long period of the year that is 06
months, there are two groups of this type of
difference completely opposite, the first is the
one where the differences of the mean radiant
temperature are present, it includes the Jewish
Museum in Berlin and the MAXXI Museum in
Rome (Figure 08).
For this purpose we mention the case of the
Jewish Museum of Berlin or for the two periods
of the mid-season, for the morning 02° and 08°,
at midday the distribution will remain with
equality but we will have 04 segments of each
temperature 02° and 08°, the route will be
composed of 04 segments, divided equally on
two temperatures, for the afternoon we will
have three temperatures, 02 segments of 02°,
07 segments of 08° and 06 segments of 12°.
Figure 08: Diagram of variation in number of temperature
segments, daily and seasonal variations
The second group is the one where these
Differences are absent and we find two types
of museums in this category, the Museum of
Modern Art and Architecture in Stockholm and
the Guggenheim Museum in Bilbao.
In the case of the Guggenheim Museum in
Bilbao, the route consists of a single segment
with a mean radiant temperature of 09° and
those for the three periods of the day. In the
case of the Museum of Modern Art and
Architecture in Stockholm the route consists of
05 segments spread out at 03 over a
temperature of 05° and 02 segment for a
temperature of 09°.
Figure 09: the route plan
For these four types of museum buildings in
Figure 10, the route is labyrinth type, however
for the Maxxi and the Jewish Museum this
labyrinth has a conceptual character of
linearity, and for the Museum of Modern Art
and Architecture in Stockholm and the
Guggenheim Museum in Bilbao, a perfect
labyrinth.

4.3. Correspondence and Recommendation:
First, we studied the correspondence between
the comfort of the building and that of the
route with the software statestica 07. This
recommendation concerns directly the
museums of our case studies and those of the
same formal configuration, the
recommendation will take effect if we respect
from the design: Optimal shape / appropriate
route / optimal mean radiant temperature:
The optimal architectural form is the
simple form (primary), simple forms are
characterized by the existence of
temperature differences that will last no
more than 03 months (the time of a
season). For the type of route, we
recommend a route with Full
Configuration, all varieties are required
(simple, centered, or zigzag).
The mid-season differences which can
affect the museum route over a period
of 06 months, very often characterize
the architectural forms having kept 50%
of their simple primary form, it will be
necessary to propose the most
compact architectural forms possible
and without disengagement, as far as
the route is concerned, we propose the
routes with Integral Configuration.
The mid-season differences are also
absent in the case of museums with
complex shape (organic form), or the
route is often labyrinthine or mixed type
seems the most appropriate, it will
however be necessary to find solutions
for the winter and summer periods.
4.4. The birth of the thermal topology:
The segmentation method we have proposed
in this paper has nothing to do with metric
dimensions of space, it depends on changes in
temperature in space. While looking for a
meaning of this segmentation in the field of
thermal, we found that this segmentation
corresponds to what O. Gregory and A.
Kumbaro (2013) had named the “thermal
topology”.
The thermal topology has not been evoked
where to present in various works of urban
planning or architecture, however it is related
to the field of the physics of the buildings. The
notion of topology designates the thermal
balance, it is related to them different regimes
of heat flow in the wall or within the space
itself. Topology is used in Thermomotor
simulations to qualify color (pixel) variations for
each image rendering and each temperature.
If we take the museum route in relation to the
visitor's movement, we will notice that each
segment corresponds to a specific
temperature, or we pass from one temperature
to another through a transition (a thermal
event corresponding to the change in
temperature) the segments in this case can be
called "sequence", and we can thus define
thermal topology as the transformations or
14. JOURNAL OF CONTEMPORARY URBAN AFFAIRS, 2(3), 122-136 / 2018
Selma SARAOUI, Azeddine Belakehal, Abdelghani ATTAR, Amar BENNADJI 135
discontinuities affecting the mean radiant
temperature throughout route and we can
then propose a new method of analysis based
on temperature variation named sequential
analysis. This new way of reading the space
topologically will allow to qualify the
architectural space from the thermal point of
view "topologically", or within the route we can
find several discontinuities based on the
variations of temperatures.
This new methodological approach, linked to
the thermal environment, can support
simulation in order to improve the thermal
performance of a design, or the study of a
possible correction based on the micro (detail)
and not the Marco (the whole project). The
method of sequential analysis of ambient
topologies (Saraoui.S, Belakehal, A, and al,
2018) had already been tested on the museum
route for the sound and light ambiences.
5. Conclusion:
Museums are very important projects in our
time, their importance emanates from the
architectural aspect of the external form which
plays a very important role in contemporary
museums. If from a conceptual point of view
the architect displays a particular intention for
visual comfort and daylight in museum, the
concept of thermal comfort remains
ambiguous and often treated after the
realization. However, it is essential to know how
to choose the appropriate forms so that the
piece of art do not deteriorate under the
effect of variation of temperature and
humidity.
The museum route is the link between the
external architectural aspect and the interior of
the museum space, whether it is an architect's
choice, an imposed constraint or a result. It is
the visitors' space on which the whole visit rests,
the space in which visitors are invaded by
sensations. This route can also be the place of
variation of an essential element of comfort
which is the mean radiant temperature
influencing the visitors' feeling.
In this paper we have taken as elements to
analyze the mean radiant temperature which
gives an overall idea on the thermal comfort.
We first analyzed the thermal comfort of the
museums in question as a building, the results of
this part seemed too general and without any
particular relationship. The evaluation of the
museum through its route, allowed us to detect
the temperature differences that can
characterize each type of museum, first for the
periods of the most unfavorable days, then for
each season. This allowed us to make
recommendations for the choice of the form
and the typology of route which goes with, this
reflection related to the design of the museums
makes it possible to reduce the consumption of
energy.
Approaching the museum route by means of
the segmentation method by mean radiant
temperature interval, put the emphasis on a
new methodological approach that can bring
a new definition to the museum space based
on the discontinuities or temperature
differences that can characterize the route,
This new way of reading space we have called
“thermal topology” can define new spatiality
of architectural space other than that based
on dimension.
