The fibre reinforced concrete can offer a suitable, practical and inexpensive method for overcoming micro-cracks and similar type of deficiencies. Since concrete is weak in tension hence some actions must be adopted to overcome this shortage. Human hair is strong in worry; hence it can be used as a fibre reinforcement material. Hair Fibre (HF) an alternate non-degradable matter is available in profusion and at a very cheap cost. It also creates environmental problem for its decompositions. Present studies has been undertaken to study the effect of human hair on plain cement concrete on the basis of its compressive strength and cracking control to economize concrete and to reduce environmental problems. Experiments were conducted on concrete with various percentages of human hair fibre 0.25% by weight of concrete. For each combination of proportions of concrete are tested for their mechanical properties.
High performance concrete is used widely due to its high strength and durability. Proper curing is required to meet strength and durability requirements .improper curing affects the strength and durability. Self-curing concrete is one of the special concretes that mitigate insufficient curing due to human negligence, concreting in heights and sloped roof or thickness of concrete is high where percolation of water to interior is difficult. The present study involves the use of super-absorbent polymer in concrete which helps in self-curing and assists in attaining better hydration and strength. Here durability properties such as water absorption, porosity, resistance to sea water, resistance to acid, sorptivity is studied for self-curing concrete with and without fibres. Incorporating fibres into concrete is not only an effective way to enhance concrete tensile stress, but also fracture toughness, impact strength, durability etc. M60 grade concrete is used for study. In this investigation Self-curing concrete was made by replacement of cement by 6% of Silica fume and Super Absorbent Polymer added at various range of 0%, 0.2%, 0.3%, and 0.4% of cement along with 3 % of fibre.
This project provides a summary of “Investigation on Hybrid Concrete Using Steel and Polypropylene Fibre”. The effect of hybrid fibres on the mechanical properties of concrete mixture is studied in the present investigation. Steel fibres of 1% and polypropylene fibres 0.035% were added together to form a hybrid fibre reinforced concrete. Mechanical properties such as compressive strength, split tensile strength and flexural strength were determined. Hybridization refers to combination of different types of fibres. The purpose of combining the fibres is to improve the multiple properties of concrete mixture. The behavioural efficiency of this composite material is far superior to that of plain and mono fibre reinforced concrete. The addition of fibre is helpful to improve the fracture properties of concrete. The hybrid fibres are comprehensively being used in rigid pavements, airfield pavements, flexible pavements, earthquake-resistant etc. The Hybrid fibre reinforced concrete cubes, cylinders and beams will be casted and finally test and find out the compressive strength, split tensile strength and flexural strength of concrete specimens.

Slurry infiltrated fibrous concrete (SIFCON) is a recently developed construction material using steel fibres and cement matrix. The matrix consists of cement slurry and infiltration is usually accomplished by gravity flow. SIFCON is the combination of cement, fibre and water with some admixtures. SIFCON has both high strength as well as large ductility. The properties of SIFCON are achieved through an optimized combination of matrix properties, fibre content and interface characteristics between fibre and matrix. This experiment is carried out to study the compressive strength, flexural strength of SIFCON. The results are then compared with that of Conventional Concrete and Fibre Reinforced Concrete.
Use of groundnut shell ash as the partial replacement for cement in concrete production. 7days and 28 days compressive strength and density are calculated. The percentage replacement of OPC contrasts to the control 0% replacement about 15%. The results commonly show a decrease in density and compressive strength as the percentage replacement with GSA increases signifying less hydration with cement. Based on a general analysis of the results as well as the logical assessment to the acceptable standard, a percentage replacement of 10% is proposed for sustainable construction, especially in mass concrete construction.
Fibre Reinforced Polymer (FRP) Composite is an alternative solution for strengthening of structure widely used in the world. Advantages given by this material is properly considered such as resistance against corrosion, no heavy additional equipment in application. It is economical to rehabilitate the structures using FRP sheets. This project deals with the study of retrofitting the RC beams using Glass fibre reinforced polymer (GFRP) and Polypropylene fibre reinforced polymer (PFRP). Seven beams of cross section 150 X 300mm and length of 1.5m were casted, one is control beam and remaining six beams were divided in to two groups, one group is strengthened at bottom and another group is strengthened at bottom and both sides of the beam (U shape). 1st one is monolithic wrapping of GFRP, 2nd is monolithic wrapping of PFRP and the 3rd is hybrid wrapping of both GFRP and PFRP. The effective use of GFRP and PFRP in strengthening of RC beams was studied by measuring the load carrying capacity, ductile behaviour and by observing failure modes. Tests results reveal that strengthened beams gives more load carrying capacity and also showed good ductile behaviour compared to control beam.
The significance of the title the project comes to front with designing structure of the pressure vessel for static loading and its assessment by Ansys, is basically a project concerned with design of different pressure vessel elements such as shell, Dish end, working manhole, hold up leg based on standards and codes; and progression of shell and dish end analysed by ansys. The key feature integrated in the project is to ensure the performance of pressure vessel in case of fluctuating loads. Such as selecting the material based on ASME codes, and then designing on the standards measures with referring standard manuals based on ASME. Further we have included the different manufacturing methods practice by the firm and different aspects of it. And step by step approaches to the NTD method carry out by the firm followed with standards and also integrated within the report work. This will be building a clear picture of this method among the reader. Conclusively, this modus of design based on practical standard and codes, can be employed on practical design of pressure vessel as per required by the industry or the problem statement given associated to the field of pressure vessel.
All materials used for constructions and building made of structural elements are subjected to physical wear during use. Corrosion is a economical based problem. Corrosion causes damages in material and leads to destruction of structures ultimately affect the environment. Corrosion is a chemical or electrochemical thing which can attack any metal through reaction by the surrounding environment and the importance of corrosion studies is two folds. The project is aimed at preventing corrosion that is minimising the rate of corrosion using polypropylene fibre and epoxy coating.
The innovative composite materials such as Graphite, Carbon, Kevlar and Glass with suitable resins are widely used because of their high specific strength (strength/density) and high specific modulus (modulus/density). Carbon fibres are among the most popular reinforcement additives for polymer based composites, to be used in all those applications where very excellent mechanical performances are compulsory. The technology of modern composite materials provides outstanding mechanical results to finished parts whose overall behaviour can vastly exceed many metallic alloys, even the most sophisticated. Advanced composite materials seem ideally suited for long, power driver shaft (propeller shaft) applications. Their elastic properties can be tailored to increase the torque they can carry as well as the rotational speed at which they operate. The drive shafts are used in automotive, aircraft and aerospace applications. The automotive industry is exploiting composite material technology for structural components construction in order to obtain the reduction of the weight without decrease in vehicle quality and reliability. It is known that energy conservation is one of the most important objectives in vehicle design and reduction of weight is one of the most effective measures to obtain this result. Actually, there is almost a direct proportionality between the weight of a vehicle and its fuel consumption, particularly in city driving.
Cups of various shapes and sizes are needed in pressure vessels and aerosol cans, in automobiles, in electronics devices and in many other industrial applications. Deep drawing, spinning, hydro forming, hydro mechanical forming are methods, among others, used for the production of shells Through there are several methods of forming these shells, hydro forming, hydro mechanical forming and forming against hydraulic counter pressure produces shells with very little thinning of the metal. Conventional deep drawing can produce good quality shells at high rate of production. In deep drawing blank holding force is needed to suppress wrinkling of the flange being drawn-in. In the recent years friction actuated blank holding technique has been developed for drawing cylindrical hemispherical and conical cups. In the present work, Finite element technique is used for simulating the deep drawing process with blank holding force on a single action press for drawing the cups. The process is carried out for AISI304 stainless steel and AL100 materials at different conditions; the effect of friction at a given blank holding force on peak drawing load of cup is presented in the report. The process of deep drawing AISI304 stainless steel and AL1100 materials is developed using finite element simulation and the peak load value shall help in choosing correct press and die sets.
Nowadays, the use of Self–compacting Concrete (SCC) is spreading worldwide because of its very attractive properties in the fresh state as well as after hardening. Several attempts have been made in the recent years to study about the strength and behaviour of SCC. However, only few studies have been conducted on the strength and behaviour of structural elements made on Reinforced Self Compacting Concrete beam. Therefore, an attempt has been made in the present investigation to study the effect of the strength and behaviour of structural beam elements subjected to flexure. The strength of members in the design and behaviour of shear strength is an important issue in structural design. There are several modes of failure in concrete structural members like shear, flexure. Due to the fragility of concrete structures, shear failure is one of the most important and undesirable modes of failure. Hence, Reinforced Concrete (RC) members are used to resist shear failure. Because of the complexity of shear mechanisms of reinforced concrete beams and various influencing parameters, it is difficult to establish an overall model to provide accurate estimation of shear strength. Hence, exact values of shear strength are unknown. Several empirical formulas are proposed in the literature and concrete codes for the prediction of RC beams resistance. The American Concrete Institute (ACI) and Indian Standard (IS) code has been widely used in structural design. In the last decades, numerous works have been undertaken to improve the ability of empirical formula to predict the shear behaviour of concrete structural member. Shear reinforcement is used in concrete beam to preserve the overall integrity of the concrete contribution allowing the development of additional shear forces.
From last many decades, usage of concrete has increased on large scale all over the world. Concrete ingredients used are becoming more costly day by day and also demand for the same is increasing widely all over. These ingredients are also extinguishing with time and some of them are also polluting the surrounding environment on large scale. One of the main ingredients is cement, while production of cement CO2 is emitted out. Replacement of cement by a pozzalanic material named Ground Granulated Blast Furnace Slag, which is by-product or waste product of steel manufacturing industries. Ground Granulated Blast Furnace Slag act as cost reducing ingredient and also increase many mechanical properties of concrete. Glass fibre of 12mm size was also added to increase both compressive and tensile strength of concrete. This concrete is more environments friendly and will give more life to concrete. To maintain workability for lower water/cement ratio and to maintain the effect of admixture added, Super plasticiser is added by trial and error method. Mechanical properties of pozzalanic concrete using silica fume show that this concrete gives better compressive strength and increases durability of concrete. Recon fibre also increases mechanical properties like compressive strength, flexural strength and split tensile strength of concrete. This page revives all details of the material, test to be conducted on concrete using the supplementary admixture and literature showing the advantages of using silica fume and recon Fibre in concrete in different proportion.
The aim of the paper is to find the shear behaviour of hybrid fibre reinforced geo polymer concrete beams under two point loading. Subsequently it involves the preparation of fly ash and GGBS based geo polymer concrete. For geo polymer concrete trial and error process is used to determine the mix proportion which will have strength in range of 40-50 MPa. This concrete is used for the casting of fly ash and GGBS-based hybrid fibre reinforced geo polymer concrete beams (F&GHGPC) specimen which will be tested to find ultimate load and behaviour under two point monotonic loading. For the purpose of comparison, fly ash based hybrid fibre reinforced geo polymer concrete beams (FHGPC) casted and also tested less than two point monotonic loading. The main objective of the study is to look into the shear behaviour of hybrid fibre reinforced geo polymer concrete beams.
Optimization of time and cost in construction projects has been subjected to extensive research since the development of the Critical Path Method (CPM). Time and cost as two critical objectives of construction project management, are not independent but intricately related. In reality due to different uncertainties, the actual cost and time of each option is not certainly known for the manager in advance. The methods for optimizing time and cost of construction projects range from mathematical methods to evolutionary based methods. Nowadays, more and more the awareness is growing that fast tracking also has evidential consequences for the earlier design phases. The existing methods of time and cost optimization the fast track method is one of the most recognized methodologies for reducing construction time and project schedules. The fast track method is applied to a selected case study using Microsoft project professional. The works at each stage of the project are overlapped to reduce the total project duration and deliver the project earlier than the time estimated by the conventional method of project planning and scheduling. The overlapping of the design phase and the construction phase in each stage of work has been crucial in reducing the total duration of the project. The case study considered for this study is a commercial project named Hyatt regency which is located at Gachibowli in Hyderabad. The total duration of the project is reduced from 940 days to 766 days which is 18.51%. The project is delivered to the client 6 months earlier. The earlier delivery of the project benefit to both client as well as contractor.

The venture is gone for making the model of the wheel edge utilizing PRO-E Software. The wheel edge which is subjected to different mechanical powers, encounters straight static anxiety and these anxiety appropriations PLOTS are gotten by the utilization of a more adaptable bundle ANSYS, a Finite component bundle.
Pervious concrete (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity used for concrete flat applications allows water from precipitation and other sources to pass directly through, thereby reducing the run-off from a site and allowing ground water recharge. Pervious concrete is made using large aggregates with little to no fine aggregates. The concrete paste then coats the aggregates and allows water to pass through the concrete slab. Pervious concrete is traditionally used in parking areas, areas with light traffic, residential streets, pedestrian walkways, and green houses. It is an important application for sustainable construction and is one of many low impact development techniques used by builders to protect water quality. In this project we made pervious concrete in the ratios of 1:6, 1:8, and 1:10 and obtained the values of compressive strength, tensile strength, and water absorption for 7 & 28 days. This result reveals that this concrete can be used as pavement in roads.

Exploring the Experiences of Gender-Based Violence
and The Associated Psychosocial and Mental Health
Issues of Filipino HIV-Positives: Implications for
Psychological Practice
Evangeline R Castronuevo-Ruga1, Normita A Atrillano2
Abstract: The phenomenon of gender-based violence has generated attention from research practitioners and helping professionals since
the surge of the women’s movement three or so decades ago in the Philippines. At about the same time, the HIV-AIDS gained similar
attention with the disclosure of the first ever case of the country in the mid-80s. Only recently, however, has the intersectionality of these
two phenomena been looked into by the research community in other countries and has yet to see parallel response locally. This research,
therefore, attempts to map out the lived experiences of People Living with Human Immuno Deficiency Virus (PLHIV) who have undergone
gender-based violence (GBV). It specially looks into the consequent psychosocial and mental health issues. Using focus group discussion with
24 purposively sampled participants from the highly vulnerable groups based in three major Philippine cities, thematic analysis reveals that
the participants experienced various forms of gender-based violence, e.g., sexual, emotional/psychological, economic, verbal, physical) and
expressions of stigma and discrimination, which in turn, led to manifestations of different emotional and psychological trauma, depression,
internalized homophobia, greater health risks and risk-taking behaviours, among others. It might be worthwhile to consider the possibility
that the consequent risk-taking and self-injurious tendencies played a role in their eventual contraction of HIV.

Abstract: Drought is a phenomenon of extreme water shortage that has significant economic, social, environmental and human life
impact. Streamflow drought characteristics and properties are useful in the design of hydro-technical projects, water resources planning and
management purposes. Information on low flow magnitude, frequency, probability and return period are very crucial in analysing
streamflow drought at the operational level in public water supply. The objectives of this study are to determine the characteristics of low
flow for every streamflow station in the Selangor region. The estimation of minimum storage draft-rate with the probability of low flow
return periods of 2, 5, 10, 20, and 50 years is presented in this paper.

Politeness and Intimacy in Application Letters of
Three Cultural Groups in Mindanao
Helen G Juaini1
Abstract: 150 application letters from the three cultural groups in Mindano, namely Sinama, Subanen, and Tausug have been analysed
in a mixed-method design. The focus of the study is on the two features of politeness and intimacy. In the quantitative analysis, the model
proposed by Brown & Levinson (1987) and that of Columns (2005) which have drawn upon the features of indirectness in requesting and
the length of letters as the indicators of politeness are used. In the qualitative and descriptive analysis formality in salutation and opening
clause as well as the use of abbreviated forms are taken into account. The result shows that Tausug use the politest style in their application
letters, followed by Sinama and Subanen respectively. On the other hand, Sinama, Subanen, and Tausug use the least intimate style in their
business letters. The findings are hoped to help better inter-cultural understanding, especially with respect to written rhetorical
characteristics.

The significance of the title the project comes to front with designing structure of the pressure vessel for static loading and its assessment by Ansys, is basically a project concerned with design of different pressure vessel elements such as shell, Dish end, working manhole, hold up leg based on standards and codes; and progression of shell and dish end analysed by ansys. The key feature integrated in the project is to ensure the performance of pressure vessel in case of fluctuating loads. Such as selecting the material based on ASME codes, and then designing on the standards measures with referring standard manuals based on ASME. Further we have included the different manufacturing methods practice by the firm and different aspects of it. And step by step approaches to the NTD method carry out by the firm followed with standards and also integrated within the report work. This will be building a clear picture of this method among the reader. Conclusively, this modus of design based on practical standard and codes, can be employed on practical design of pressure vessel as per required by the industry or the problem statement given associated to the field of pressure vessel.
All materials used for constructions and building made of structural elements are subjected to physical wear during use. Corrosion is a economical based problem. Corrosion causes damages in material and leads to destruction of structures ultimately affect the environment. Corrosion is a chemical or electrochemical thing which can attack any metal through reaction by the surrounding environment and the importance of corrosion studies is two folds. The project is aimed at preventing corrosion that is minimising the rate of corrosion using polypropylene fibre and epoxy coating.
The innovative composite materials such as Graphite, Carbon, Kevlar and Glass with suitable resins are widely used because of their high specific strength (strength/density) and high specific modulus (modulus/density). Carbon fibres are among the most popular reinforcement additives for polymer based composites, to be used in all those applications where very excellent mechanical performances are compulsory. The technology of modern composite materials provides outstanding mechanical results to finished parts whose overall behaviour can vastly exceed many metallic alloys, even the most sophisticated. Advanced composite materials seem ideally suited for long, power driver shaft (propeller shaft) applications. Their elastic properties can be tailored to increase the torque they can carry as well as the rotational speed at which they operate. The drive shafts are used in automotive, aircraft and aerospace applications. The automotive industry is exploiting composite material technology for structural components construction in order to obtain the reduction of the weight without decrease in vehicle quality and reliability. It is known that energy conservation is one of the most important objectives in vehicle design and reduction of weight is one of the most effective measures to obtain this result. Actually, there is almost a direct proportionality between the weight of a vehicle and its fuel consumption, particularly in city driving.
Cups of various shapes and sizes are needed in pressure vessels and aerosol cans, in automobiles, in electronics devices and in many other industrial applications. Deep drawing, spinning, hydro forming, hydro mechanical forming are methods, among others, used for the production of shells Through there are several methods of forming these shells, hydro forming, hydro mechanical forming and forming against hydraulic counter pressure produces shells with very little thinning of the metal. Conventional deep drawing can produce good quality shells at high rate of production. In deep drawing blank holding force is needed to suppress wrinkling of the flange being drawn-in. In the recent years friction actuated blank holding technique has been developed for drawing cylindrical hemispherical and conical cups. In the present work, Finite element technique is used for simulating the deep drawing process with blank holding force on a single action press for drawing the cups. The process is carried out for AISI304 stainless steel and AL100 materials at different conditions; the effect of friction at a given blank holding force on peak drawing load of cup is presented in the report. The process of deep drawing AISI304 stainless steel and AL1100 materials is developed using finite element simulation and the peak load value shall help in choosing correct press and die sets.
Nowadays, the use of Self–compacting Concrete (SCC) is spreading worldwide because of its very attractive properties in the fresh state as well as after hardening. Several attempts have been made in the recent years to study about the strength and behaviour of SCC. However, only few studies have been conducted on the strength and behaviour of structural elements made on Reinforced Self Compacting Concrete beam. Therefore, an attempt has been made in the present investigation to study the effect of the strength and behaviour of structural beam elements subjected to flexure. The strength of members in the design and behaviour of shear strength is an important issue in structural design. There are several modes of failure in concrete structural members like shear, flexure. Due to the fragility of concrete structures, shear failure is one of the most important and undesirable modes of failure. Hence, Reinforced Concrete (RC) members are used to resist shear failure. Because of the complexity of shear mechanisms of reinforced concrete beams and various influencing parameters, it is difficult to establish an overall model to provide accurate estimation of shear strength. Hence, exact values of shear strength are unknown. Several empirical formulas are proposed in the literature and concrete codes for the prediction of RC beams resistance. The American Concrete Institute (ACI) and Indian Standard (IS) code has been widely used in structural design. In the last decades, numerous works have been undertaken to improve the ability of empirical formula to predict the shear behaviour of concrete structural member. Shear reinforcement is used in concrete beam to preserve the overall integrity of the concrete contribution allowing the development of additional shear forces.
From last many decades, usage of concrete has increased on large scale all over the world. Concrete ingredients used are becoming more costly day by day and also demand for the same is increasing widely all over. These ingredients are also extinguishing with time and some of them are also polluting the surrounding environment on large scale. One of the main ingredients is cement, while production of cement CO2 is emitted out. Replacement of cement by a pozzalanic material named Ground Granulated Blast Furnace Slag, which is by-product or waste product of steel manufacturing industries. Ground Granulated Blast Furnace Slag act as cost reducing ingredient and also increase many mechanical properties of concrete. Glass fibre of 12mm size was also added to increase both compressive and tensile strength of concrete. This concrete is more environments friendly and will give more life to concrete. To maintain workability for lower water/cement ratio and to maintain the effect of admixture added, Super plasticiser is added by trial and error method. Mechanical properties of pozzalanic concrete using silica fume show that this concrete gives better compressive strength and increases durability of concrete. Recon fibre also increases mechanical properties like compressive strength, flexural strength and split tensile strength of concrete. This page revives all details of the material, test to be conducted on concrete using the supplementary admixture and literature showing the advantages of using silica fume and recon Fibre in concrete in different proportion.
The aim of the paper is to find the shear behaviour of hybrid fibre reinforced geo polymer concrete beams under two point loading. Subsequently it involves the preparation of fly ash and GGBS based geo polymer concrete. For geo polymer concrete trial and error process is used to determine the mix proportion which will have strength in range of 40-50 MPa. This concrete is used for the casting of fly ash and GGBS-based hybrid fibre reinforced geo polymer concrete beams (F&GHGPC) specimen which will be tested to find ultimate load and behaviour under two point monotonic loading. For the purpose of comparison, fly ash based hybrid fibre reinforced geo polymer concrete beams (FHGPC) casted and also tested less than two point monotonic loading. The main objective of the study is to look into the shear behaviour of hybrid fibre reinforced geo polymer concrete beams.
Optimization of time and cost in construction projects has been subjected to extensive research since the development of the Critical Path Method (CPM). Time and cost as two critical objectives of construction project management, are not independent but intricately related. In reality due to different uncertainties, the actual cost and time of each option is not certainly known for the manager in advance. The methods for optimizing time and cost of construction projects range from mathematical methods to evolutionary based methods. Nowadays, more and more the awareness is growing that fast tracking also has evidential consequences for the earlier design phases. The existing methods of time and cost optimization the fast track method is one of the most recognized methodologies for reducing construction time and project schedules. The fast track method is applied to a selected case study using Microsoft project professional. The works at each stage of the project are overlapped to reduce the total project duration and deliver the project earlier than the time estimated by the conventional method of project planning and scheduling. The overlapping of the design phase and the construction phase in each stage of work has been crucial in reducing the total duration of the project. The case study considered for this study is a commercial project named Hyatt regency which is located at Gachibowli in Hyderabad. The total duration of the project is reduced from 940 days to 766 days which is 18.51%. The project is delivered to the client 6 months earlier. The earlier delivery of the project benefit to both client as well as contractor.
PC Aided building framework gives add up to framework way to deal with new item advancement. The utilization of PC in Design Analysis and advancement procedure, which is for the most part iterative in nature, decreases the dreary occupation and expands the accuracy. This extend includes one such model of wheel, which is as indicated by the determination given by the Japanese Industrial Standards. The wheel edge has been broke down for two conditions. Bowing continuance test, Radial perseverance test, In Radial continuance test, taking after three conditions have been dissected. The venture is gone for making the model of the wheel edge utilizing PRO-E Software. The wheel edge which is subjected to different mechanical powers, encounters straight static anxiety and these anxiety appropriations PLOTS are gotten by the utilization of a more adaptable bundle ANSYS, a Finite component bundle.
Pervious concrete (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity used for concrete flat applications allows water from precipitation and other sources to pass directly through, thereby reducing the run-off from a site and allowing ground water recharge. Pervious concrete is made using large aggregates with little to no fine aggregates. The concrete paste then coats the aggregates and allows water to pass through the concrete slab. Pervious concrete is traditionally used in parking areas, areas with light traffic, residential streets, pedestrian walkways, and green houses. It is an important application for sustainable construction and is one of many low impact development techniques used by builders to protect water quality. In this project we made pervious concrete in the ratios of 1:6, 1:8, and 1:10 and obtained the values of compressive strength, tensile strength, and water absorption for 7 & 28 days. This result reveals that this concrete can be used as pavement in roads.

Exploring the Experiences of Gender-Based Violence
and The Associated Psychosocial and Mental Health
Issues of Filipino HIV-Positives: Implications for
Psychological Practice
Evangeline R Castronuevo-Ruga1, Normita A Atrillano2
Abstract: The phenomenon of gender-based violence has generated attention from research practitioners and helping professionals since
the surge of the women’s movement three or so decades ago in the Philippines. At about the same time, the HIV-AIDS gained similar
attention with the disclosure of the first ever case of the country in the mid-80s. Only recently, however, has the intersectionality of these
two phenomena been looked into by the research community in other countries and has yet to see parallel response locally. This research,
therefore, attempts to map out the lived experiences of People Living with Human Immuno Deficiency Virus (PLHIV) who have undergone
gender-based violence (GBV). It specially looks into the consequent psychosocial and mental health issues. Using focus group discussion with
24 purposively sampled participants from the highly vulnerable groups based in three major Philippine cities, thematic analysis reveals that
the participants experienced various forms of gender-based violence, e.g., sexual, emotional/psychological, economic, verbal, physical) and
expressions of stigma and discrimination, which in turn, led to manifestations of different emotional and psychological trauma, depression,
internalized homophobia, greater health risks and risk-taking behaviours, among others. It might be worthwhile to consider the possibility
that the consequent risk-taking and self-injurious tendencies played a role in their eventual contraction of HIV.

Politeness and Intimacy in Application Letters of
Three Cultural Groups in Mindanao
Helen G Juaini1
Abstract: 150 application letters from the three cultural groups in Mindano, namely Sinama, Subanen, and Tausug have been analysed
in a mixed-method design. The focus of the study is on the two features of politeness and intimacy. In the quantitative analysis, the model
proposed by Brown & Levinson (1987) and that of Columns (2005) which have drawn upon the features of indirectness in requesting and
the length of letters as the indicators of politeness are used. In the qualitative and descriptive analysis formality in salutation and opening
clause as well as the use of abbreviated forms are taken into account. The result shows that Tausug use the politest style in their application
letters, followed by Sinama and Subanen respectively. On the other hand, Sinama, Subanen, and Tausug use the least intimate style in their
business letters. The findings are hoped to help better inter-cultural understanding, especially with respect to written rhetorical
characteristics.

Abstract: Recently, IoT devices such as robots, speakers, domestic electrical appliances and smart devices are provided everywhere for
everyone. While their authentication request is quite ubiquitously, namely, an authentication for sharing services, the actual
implementations are patchy schemes of variety security policies. In this study, we propose the new authentication scheme for IoT devices
without certificate authority which is fast enough as well as secure. The verification algorithm is based on suitable ciphered metric. We
define a class of such verifiable encryption and give an example for authentication. Moreover, we show the implementation which keeps
perfect secrecy by means of Shannon’s theory.
Developing a Strategic Organisational Learning
Framework to Improve Caribbean Disaster
Management Performance
Joanne Persad1
Abstract: Disasters are social constructs and require an agility and adaptability from national disaster organisations (NDOs). The
environment in which NDOs operate are complex adaptive systems environment, and organisational learning as a key approach is considered
fundamental to strengthening the ability of an NDO to perform at its best. With the potential for loss of lives, the destruction of critical
infrastructure and housing and to the risk of setting back a country’s economic development by many years, learning from the lessons of the
past, to reduce the negative impacts is critical for the onward growth of Caribbean countries which, for the most part, are small island
developing states. The Caribbean Region is the one of the most hazard prone regions in the world (Walbrent College 2012). Lessons from
disaster impacts are identified, gaps are well documented, and failures are sometimes exposed. But learning, in terms of making changes to
improve systems, performance and resilience, is questionable. The lessons must be applied for change to occur, this is part of the knowledge
management process in the context of disaster organisations. The purpose of this study is to explore the apparent inability of national
disaster organizations in the Caribbean to apply the lessons learnt from previous disasters. Three (3) Caribbean countries have been selected
for this research. It is a multiple case study where the unit of analysis is the national disaster organisation. This study is based on an
interpretive paradigm.

Abstract: The West African Sahel is a vast ecological zone separating the Sahara Desert to the north and Sudanian savannah to the
south; traversing Senegal, Mali, Burkina Faso, Niger, northern Nigeria and Chad. With a population estimated at more than 60 million
people, the region features a multiplicity of development challenges. It is home to some of the world’s most impoverished people, whose
livelihoods are mostly reliant on rain-fed agriculture. Characterized by semi-arid vegetation, the West African Sahel is one of the most
environmentally degraded ecosystems in the world. The region faces severe and recurring bouts of droughts since the 1980s, jeopardizing
environmental sustainability. During the past four decades, the West African Sahel has witnessed below-average annual precipitation, with
two severe drought periods in 1972-1973 and 1983–1984, in a development that undermined agricultural productivity and spawned
severe land degradation. Various studies have predicted even more severe climate variability and change in the region, with drier and more
frequent dry periods expected. The intergovernmental Panel on climate change (IPCC, 2007) revealed a decline in annual rainfall in West
Africa since the end of the 1960s, with a reduction of 20% to 40% observed in the periods 1931-1960 and 1968–1990. Repeated
droughts, fuelled by climate change, have undermined land productivity, turning arable soils into marginal lands, and rendering land
resources vulnerable to such anthropogenic activities as over-grazing, agricultural intensification and deforestation, which are common
practices across the region. The major objective of this paper is to shed light on climate change and land degradation patterns in the West
African Sahel. It employs empirical data to analyse the trends, with particular emphasis on Mali, Niger and Senegal. The study reveals
considerable threats posed by the twin scourges of climate change and land degradation to food security, environmental sustainability and
regional stability.

Abstract: The online clothing businesses have seen a considerable rise in recent times, with a high and growing demand. The purpose of
this study is to determine the factors that play significant roles in creating purchase intention towards the online clothing products in
Bangladesh. Secondary research was used to build the model of customer purchase intention. A structured questionnaire was employed to
gather data and test the model. Factor analysis and regression were used to test the model. The regression model suggested that customer
purchase intention was induced most by the online marketing activities of the online retailers, followed by pricing strategy implemented and
sense of security provided (in that order). To understand customer purchase intentions better, it may be important to look at additional
factors or seek better measures of the constructs. The study suggests that online retailers should heavily focus on online promotions and
pricing.

Abstract: Unlike other industries, the construction industry is characterized by its heavy dependence on labour force with most work done
by workers. Still, the industry is witnessing the declining influx of young workers and the rising turnover rates of skilled workers due to such
issues as the advancement of 3D industry, negative image and absence of an established wage system. Hence, this paper proposes an
alternative scheme that would help improve the wage system and work environment for skilled construction workers in Korea.
Mastering the Recycling of Masonry while building
Tadao Ando’s Private Gallery in Lincoln Park,
Chicago
Daniel Joseph Whittaker1
Abstract: The notion of a great presence of masonry rarely conjures up the likes of buildings by master architect, Tadao Ando san of
Osaka, Japan, who is better known for his sublime shaping of space with planar forms of site-cast concrete. Perhaps though, one may recall
the ‘historical intervention’ on a grand scale—the now nine-year-old Punta Della Dogan a project (2009) in Venice, Italy, as prima facie
evidence of his dialogue with a vast quantity of ancient masonry in the Laguna. However, a new project by Ando, recently opened in
Chicago, Illinois (October 2018), presents the private-museum-gallery-going public with a new North American delight. Here, the senses
are able to indulge in a hybrid set of experiences shaped by masonry, concrete, and white painted plaster surfaces. This paper explores how
the modern concrete master has expanded his dynamic architectural vocabulary utilizing what is known as Chicago common brick: a soft,
Lake Michigan-sand and clay based fired brick, and incorporated it into his most recent private commission located in Lincoln Park,
Chicago.

Abstract: Energy consumption is an important factor of com-mutational power these days. Large scale energy consumption results in bad
system performance and high cost. To access frequently used data, we place it in Cache. Cache provides us opportunity to access that data in
a small time. Cache memory helps in retrieving data in minimum time improving the system performance and reducing power consumption.
Due to limited size of Cache, replacement algorithms used to make space for new data. There are many existing cache replacement
algorithms for example LRU, LFU, MRU, FIFO etc. Existing algorithms consume a lot of energy while replacing cold blocks of data.
Replacement algorithms are usually designed to reduce miss rate and increase hit rate. These algorithms replace cold blocks (not going to use
in future) and due to large number of cold blocks, they consume lot of energy. This paper proposes an energy and computation efficient cache
replacement algorithm that put only hot blocks in action instead of removing cold blocks. This paper also discusses different replacement
algorithms proposed in different papers and compare these algorithms on basis of different parameters mainly energy consumption. In our
experiments we have found LRU and FIFO as best replacement algorithms for Increased hit rates and Energy efficiency respectively.

Wireless sensor networks can provide low cost solution accompanied with limited storage, computational capability and power for verity of real-world problems and become essential factor when sensor nodes are arbitrarily deployed in a hostile environment. The cluster head selection technique is also one of the good approaches to reduce energy consumption in wireless sensor networks. The lifetime of wireless sensor networks is extended by using the uniform cluster head selection and balancing the network loading among the clusters. We have reviewed various energy efficient schemes apply in WSNs of which we concentrated on selection of cluster head approach and proposed an new method called Sleep Scheduling Routing with in clusters for Energy Efficient [SSREE]in which some nodes in clusters are usually put to sleep to conserve energy, and this helps to prolong the network lifetime. EASSR selects a node as a cluster head if its residual energy is more than system average energy and have less energy consumption rate in previous round. Then, an Performance analysis and compared statistic results of SSREE shows of the significant improvement over existing protocol LEACH, SEP and M-GEAR protocol in terms of lifetime of network and data units gathered at BS.
Due to rapid urbanization the manufacturing processes of conventional building materials pollutes air, water and land. Hence in order to fulfil the increasing demand it is required to adopt a cost effective, eco-friendly technologies by improving the traditional techniques with the usage of available local materials. Agro – industrial and other solid waste disposal is another serious issue of concern in most of developing countries. The present paper explores the potential application of agro-waste as an ingredient for alternate sustainable construction materials.
A correct node operation and power administration are significant issues in the wireless sensor network system. Ultrasonic, dead reckoning, and radio frequency information is obtained by using localization mechanism and worked through a specific filter algorithm. In this paper, a well-organized grid deployment method is applied to split the nodes into multiple individual grids. The tiny grids are used for improved resolution and bigger grids are used to decrease the complexity of processing. The efficiency of each grid is obtained by environmental factors such as redeployed nodes, boundaries, and obstacles. To decrease the power usage, asynchronous power management method is designed. In network communication, power management method is applied by using an asynchronous awakening scheme and n-duplicate coverage algorithm is engineered for the coverage of nodes.
Permanent Magnet DC motors find wide applications in orthopaedic surgical systems. Conventional PI controller based chopper drive is being employed in these motor drives.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
