The main aim of this article is to analyse current facade techniques, water producing systems and possible profits from the application of adequate facade designs which could produce water with the consideration of the needs of inhabitants. Nowadays for certain countries lacking the financial power to provide adequate water resources, the need of water harvesting becomes more crucial. The proposed water harvesting systems aim to increase the water resources by the application on the building’s facade. On the other hand, existing double skin facades have only been used for shading, ventilation or decorative purposes. This investigation focuses specifically on the design of the facade in terms of the production of water. The case study has taken place in North Cyprus, Nicosia. A selected area will be evaluated and the need of the water will be calculated then the proposal of the new facade model will be introduced. Most importantly this proposed facade model will meet the needs of water consumption of the inhabitants. It produces 420 litre water per day by using solar energy. With this system the application uses the sun energy to extract water from the air, also the application has potential to use as multi-functional purposes since it collects water via humidity with turbine systems, it collects up to 396 litres at temperatures between 86 degrees to 104 degrees (30 to 40 degrees Celsius) and between 80% and 90% relative humidity.

Sustainable domestic wastewater treatment in urban areas
Sustainable domestic wastewater treatment in urban areasRetired from Saxion University of Applied Sciences
This document summarizes Gerard A.M. de Fraiture's contribution to an international seminar on sustainable domestic wastewater treatment in urban areas. Conventional wastewater treatment systems in western countries are not very sustainable. Research shows that anaerobic treatment, which mimics natural biological processes, is more sustainable as it recovers energy and nutrients in a decentralized manner. Promising technologies like upflow anaerobic sludge blanket reactors and recent algae technologies follow principles of separating solids from liquids and minimizing water use for transport. Simple, robust, affordable technologies at small scale can create jobs and economic opportunities while achieving sustainability goals.Newsletter 225
The document summarizes news from South America related to environment, science, technology, and health. It discusses experts calling for better monitoring and inclusion of water in development goals due to threats from human activities like dams and irrigation altering the global water system. It also reports on a conference in Germany bringing together water researchers to inform policy on water governance. Additionally, it notes a regional project cataloging humpback whales led by Chilean scientists and participation of local fishermen in ecotourism.
Recycled Water: Wastewater Poised to Be a Significant Source of The Nation's ...
A report from the National Research Council suggests that treated wastewater has the potential to be a large part of the future US water supply, though using wastewater is controversial. While water recycling is already practiced in the US for less than 1% of water, increasing reuse could provide 27% of public supply by treating the 12 billion gallons of wastewater discharged daily. The report found that treated wastewater does not pose health risks and that recycling costs vary but can be less than desalination while complementing other water sources and strategies.

How do Waste Water Treatment Devices Assist Production of Clean Water?
The sewerage projects comprise a basic infrastructure of a nation and are an indisputable indicator of development and civilization. The project pivots greatly around efficient waste water treatment devices to effectively serve the purpose.
AshleyStrobridgeLitReview
This document provides a literature review on sustainable development and greening the built environment. It defines sustainable development as having five key aspects: environmental limits, demand management, environmental efficiency, welfare efficiency, and equity. Several articles are then summarized that illustrate these aspects, such as how green buildings can improve employee health and productivity, new regulations requiring home appliances to use less energy and water, retrofitting homes to increase insulation and efficiency, using unused window space in buildings to generate solar power, examples of recycling and reuse in impoverished communities, and a system to treat human waste for use as fertilizer.
The Kailash Ecovillage project converting human excreta into organic foodstuf...
Since March 2014, a sustainably focused community located on a 0.7 hectares site in Portland, Oregon, USA, has
been undertaking an experimental composting toilet system modeled after the Water Efficiency and Sanitation
Standard (WE-Stand) set out by the International Association of Plumbing and Mechanical Officials (IAPMO).
This system collects urine and hot composts human excreta in a dry-composting toilet system for eventual
use on the community’s organic gardens. The system design reduces the need to access municipal water,
sewer, and electrical infrastructure, enhancing emergency preparedness. It conserves an otherwise wasted
nutrient flow, and safely produces a valuable compost. The system consists of urine collection vessels, multiple
portable collection containers for excreta, toilet paper, and additive, and a compost processor. Urine diversion
has allowed the community to reclaim nitrogen and other nutrients otherwise lost in conventional sewage systems,
resulting in large savings of potable water and significant carbon sequestration via topsoil creation. Logs
showed thermophilic compost temperatures. Compost and urine pathogen testing met American National Standards
Institute and National Sanitation Foundation Standard 41 requirements.
Desalination good

Heidi will discuss the global freshwater crisis and increasing demand. Emily will cover the success of desalination so far. Anna will address the economics of desalination including decreasing costs over time. Will will explore the possibility of a marketable byproduct from the desalination process.
IRJET- Desalination of Salt Water using Solar Energy
This document summarizes a research paper on desalination of salt water using solar energy. It describes a small-scale desalination system that uses solar energy as its main power source. The system consists of a glass cover, lens, and aluminum plate designed to evaporate sea water through a vapor compression process. When tested using natural sea water, the system was able to produce fresh water with over 90% rejection of salt on average. The research found that suitable modifications to solar stills could produce high outputs of fresh water even on cloudy days using minimal land area. The goal of the study was to assess the feasibility and cost-effectiveness of using solar energy for desalination plants.
Recycling can be worth it, if we focus efforts student’s n
Recycling efforts should continue, but be more focused on materials that are unsustainable to reproduce and have benefits when recycled, like aluminum cans. While recycling has positive environmental impacts by reducing waste in landfills and conserving resources, there is debate around the energy costs of recycling different materials and whether the benefits outweigh these costs. Recycling programs may be more effective if focused on materials like aluminum cans, where recycling saves substantial energy compared to producing new cans from raw materials. However, recycling other materials like plastic bottles or glass may not provide as much benefit due to the high energy costs of transportation and processing.

The document evaluates the design and water quality of rainwater harvesting systems installed in Chitra Topi, AJK. It finds that non-painted galvanized iron rooftops provide high quality rainwater, while painted roofs lead to unsafe lead levels. Water quality declines with storage time due to increased microbial activity in summer months. Turbidity exceeds standards in 96% of samples year-round. Total hardness and iron levels meet standards. The study concludes rainwater harvesting can improve access if systems use appropriate designs and management practices.

The document discusses current and future responses to changes in water availability and use for agriculture in Africa. It notes that sustaining water availability is a challenge due to increasing populations, economies, and impacts of climate change like decreased rainfall in some areas. Recommendations include adopting integrated water resource management policies, promoting rainwater harvesting and conservation technologies, rehabilitating inefficient water systems, and involving local communities in conservation efforts. The talk emphasizes the need for cross-sectoral coordination to manage land and water sustainably.
Pw presentation2011
The group "(“)Flawless(“)" presented ways to save water and introduce plants into urban environments. They discussed how demand for water will exceed supply by 2030, and proposed recycling water from washing rice and clothes. Introducing plants by walls, roofs, and using low-maintenance species were suggested to improve air, provide decoration, and keep buildings cool. Credits were given to sources of pictures and references used.
FinalPaper
Each year, hundreds of millions of units of electronic waste are disposed of, most of it improperly. When electronic waste is burned to retrieve valuable components, it releases toxic chemicals into the air, water, and soil. This pollution contaminates the environment and harms human health, increasing risks of cancer, respiratory illness, and other diseases. Improper e-waste disposal pollutes drinking water sources and renders soil unusable. Governments must take urgent action to enforce strict e-waste recycling laws and ensure all electronic waste is processed safely to prevent further environmental damage and health impacts.

Civil engineers can play a bigger role in sustainability by designing infrastructure to have less environmental impact and be more eco-friendly. This includes using photocatalytic cement that reduces air pollution and green roofs that filter air and water. Engineers should also incorporate more recycling of materials like concrete into new projects to reduce waste and energy usage from mining new resources. Educating the public on sustainability issues is also important to continue progress on protecting the environment.
Phytoremediation
Poplar trees and red oaks are helping to reduce nitrate levels in rivers through their deep root systems and ability to process nitrates. Researchers are finding that plants and soil microbes can work together through phytoremediation to remove contaminants from soils polluted by hydrocarbons, nitrates, and other pollutants. An artist in Chicago is working to remediate abandoned gas station sites using native plants selected for their ability to degrade hydrocarbons in the soil over time while creating wildlife habitat.
COLLECTOR WELLS
Energy and water are central to sustainable development and poverty reduction efforts globally. They affect all aspects of development, whether social, economic, or environmental. Sustainable energy and water are core business in meeting the Millennium Development Goals (MDGs) in most developing countries. The eight goals that comprise the MDGs build on agreements made at United Nations conferences during the 1990s.1 They represent commitments by countries around the World to reduce poverty and hunger, and to tackle ill-health, gender inequality, lack of education, lack of access to clean water and environmental degradation.

Cloning #SciChallenge2017
Cloning occurs naturally in identical twins and some plants and animals, but it is now also possible artificially. Cloning produces genetically identical individuals through asexual reproduction without mixing of genetic material. Natural cloning is seen in identical twins and some species that can reproduce without fertilization to make exact copies. Artificial cloning of animals is more complex but allows copying animals with desirable traits like increased milk production. Cloning techniques involve removing early-stage embryos and growing their cells in labs before implanting in surrogate mothers. While cloning may help with medical issues like organ transplants or infertility, it also risks less genetic variation and individuality among cloned organisms.

Freshwater: Towards a Better Understanding of a Wicked Problem
Water begets intricate and profound linkages between multiple systems. Quantitative limits to freshwater availability for human needs, variabilities in the water cycle and environmental water requirements interact with water source pollution. The arising tensions are a great challenge of immense contemporary significance that can best be described as a wickedproblem –a problem with multiple dimensions that presents unexpected consequences when engaged. Water challenges make vivid the compromises that must be made between the environment and development. These compromises surface in the conflict between ecocentric and technocentric discourse. Globally, there is evidence of numerous disciplinary and interdisciplinary water-related studies both in the past and ongoing. But there is no meta-mapping of various dimensions of such research to give a clear overview of what has been and what needs to be done. Consequences of this oversight may include unnecessary duplication of research, difficulty in articulating knowledge gaps and inability to see beyond disciplinary boundaries. The author suggests an outline of how these difficulties can be engaged. This is done through a wide-ranging literature review to identify a range of issues of focus, which issues are then themed into imperatives for water research. These imperatives are subsequently systematised using four normative descriptors: problem, drivers and mitigation measures. In combination, these descriptors articulate a spectrum of the key issues around water research. The key issues are mapped onto various academic disciplines and societal partners to outline a schema for positioning of water research. The proposed mapping can facilitate interdisciplinary and transdisciplinary (IDTD) research by allowing researchers to benefit from relevant existing bodies of knowledge while also making explicit knowledge gaps and opportunities for collaboration. By locating academic fields within different worldviews, the outlined schema reveals common ground beyond disciplinary confines around which IDTD research can be instigated.

Desalination Approach of Seawater and Brackish Water by Coconut Shell Activat...
"Engineers are challenged to develop cost effective ways to produce large quantities of water suitable for drinking, crop irrigation and commercial use for regions of the world that suffer from water shortages. Water desalination is expensive, requiring large amounts of energy and specialized equipment to convert saltwater into drinking water. The present study aims to develop a cheaper, cleaner, easy and more energy efficient way of desalinating seawater technique by using natural filters, it can help the common people as it affordable during their immediate requirements. The developed technique seemed to be very effective in reducing the concentration of seawater ions. The desalination system is developed by selecting coconut shell charcoal as the substrate material. As per the results obtained from prototype of seawater and brackish water, there is 60 reduction in chloride and 75 reduction in sodium this is mainly due to the usage of activated carbon charcoal as the filter media. It is also observed through experiments that there is 100 reduction in iron,53 reduction in sulphate, 20 reduction in total dissolved solids and 12 reduction in hardness which clearly indicates that the selected filter medias those are activated carbon charcoal, sand, laterite would be used as the filter medias for future experiments on desalination using natural filters.This work is to present an overview of current and future technologies applied to the desalination of brackish as well as seawater to produce freshwater for supplementing drinking water supplies to the common people in smaller quantity. Removal efficiency increases with the increase in contact time respectively, for both seawater and brackish water, which was considered to be maximum purification ~40 .

Consequently, inferential statistics was adapted to test the hypothesis postulated using SPSS 20.0. The findings revealed that nature of generating wastewater from hygiene and sanitation procedure among inmates using restroom and flushing toilet at the rate of about 41-50 litres of water per inmate per day causes significant flooding, as well as generate chemical compounds which catalyses air and soil pollution. Inappropriate discharge of wastewater result to of outbreak of diseases in the custodial environment resulting in high rate of cholera, typhoid, malaria and dysentery. These health challenges constitute serious socio’- economic burden for the management of the custodian centres. The study also shows significant effects of effluent pollution in the area of study at a level of 0.05% significance. Thus, recommendations were made to proffer solution to the menace of effluent discharge on pollution crises around the environment correctional centres.Similar to NANOTECHNOLOGY APPLICATIONS AND EMERGING OPPORTUNITIES FOR CLEAN WATER #scichallenge2017 (20)

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsThe debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.

Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

NANOTECHNOLOGY APPLICATIONS AND EMERGING OPPORTUNITIES FOR CLEAN WATER #scichallenge2017
- 1. Computer simulation of carbon nanotubes. by İdil Gürsoy and Selcan Çınar Yıldırım (advisor) http://i.huffpost.com/gen/1713200/images/o-CLEAN-WATER-facebook.jpg INTRODUCTION Nanoscience has great potential for water purification, which can be a solution for increasing clean water resources. In this project our goal is to design a new water filtration system that is less costly, and sustainable. PROBLEM STATEMENT The recent report entitled 'Water for People - Water for Life' of the UNESCO says that 1.1 billion people lack access to improved water supply and 2.4 billion lack access to improved sanitation. İt is also stated, that water-related diseases have affected a large amount of the population. Recent advances strongly advocate that the use of nanotecnology based water-treatment systems have potential to reduce water related diseases, and other water quality problems. However, water purifying nanoscience technologies are often complicated, and are expensive to run and maintain. RELATED WORK According to Gehrke, I., Geiser, A., & Somborn-Schulz, A. ,the adaptation of highly advanced nanotechnology to traditional process engineering offers new opportunities in technological developments for advanced water and wastewater technology processes. (Gehrke, Geiser, Somborn-Schulz, 2015) On the other hand,Fostering Nanotechnology to Address Global Challenges: Water report, which published by OECD states that the unknown impacts of nano-particles properties lies at the core of the ongoing health and safety concerns regarding the use of nanoparticles, including in water processing and treatment. (Fostering Nanotechnology to Address Global Challenges: Water, 2011, p35) Das, Hamid, Ramakrishna, and Chowdhury highlighted that the lack of cost-effective water purification technology has already aggravated the crisis of clean water and safe water for the rapidly growing population. The authors also point out that this issue which mentioned above, extremely serious and has been posing a big treat to global health, economic growth, sustainability ans social progress.

Innovations in nanotechnology for water treatment. Nanotechnology, science and applications, 8, 1. APPLICATION Among many potential applications, carbon nanotubes (CNTs) are great candidate materials for cleaning polluted water. CNTs are made of carbon, only a few nanometers across CNT membranes can remove almost all kinds of water contaminants. IDEAS We, as an imaginative innovation researchers' team, suggest that the new technique which uses CNTs for cleaning polluted water could provide a simple answer to the problem of huge costs. Our empirical data will show that CNTs, which are improved by our methods are potentially efficient adsorbents for a variety of pollutants in both drinking and environmental waters. The process will be also really well to protect public from nanotechnology risks.
