The impact of pH on the properties of β-Tricalcium phosphate synthesized from hen’s eggshells[]


Everyday millions of tons of eggshells are produced as biowaste around the world. Most of this waste is disposed of in landfills with-out any pretreatment. Eggshells in landfills produce odors and promote microbial growth as they biodegrade. The present study pro-vides a simple wet chemical method to obtain high-purity β-tricalcium phosphate (β-TCP) using eggshells hens as the calcium source (Ca) in the form of calcium nitrate and ammonium phosphate as the phosphate source (P) and controlling the pH of mixture solution in a range from 7 to 9. The observed phases of the heated mixtures were dependent on the mixing pH values. The synthesized TCP was characterized by X-Ray Diffraction (XRD), Fourier Transformed Infrared Spectroscopy (FT-IR), Transmission Electron Microscopy (TEM) and EDX analysis.


Comparative Study of Generator Volatge Performance by Varying Generator Materials using COMSOL Multiphysics.[]


This paper studies the comparative performance of generated voltage and magnetic flux distribution of an electrical machine due to the variation of stator and rotor materials using COMSOL Multyphysics. This simulation is done in 2D that shows how the circular motion of a rotor with the variation of magnetic and non magnetic materials generates an induced EMF in a stator winding. The modeling deals with both the material magnetic properties and the circuit equations related to different parts of the machine. The generated voltage is calculated as a function of time during the rotation with a single number of turn.


A Comparative Study About Scheduled Tribes in West Bengal, India[]


Tribes of India are generally known to be descendants of primitive inhabitants, many of whom have in course of history been pushed into the periphery of, and largely isolated from, India's mainstream society and culture. Just after Independence, the Constitution of India prepared two schedules for identifying various tribal and low caste groups, which are officially called 'Scheduled Tribes' (ST) and 'Scheduled Castes' (SC) respectively. The census authorities enumerate tribal and low caste and backward peoples on the basis of these detailed schedules. The lists for ST and SC groups have been substantially enlarged since its first use in the 1951 census, and the numbers of tribes and low caste groups that were declared as 'scheduled' according to the census of 1991 were 573 and 1,091 respectively. Santals are one of the major and most numerous tribes of India. They have a long cultural heritage, and they are concentrated in the eastern states of West Bengal, Bihar and Orissa . The total population of West Bengal at 2001 Census has been 80,176,197. Of this 4,406,794 persons are Scheduled Tribes (STs) constituting 5.5 per cent of the total population of the state. The state has registered 15.7 per cent decadal growth of ST population in 1991-2001. There are total thirty eight (38) notified STs in the state. The Scheduled Tribe(ST) people are engaged any type of works like Agricultural sector , Industral Work(Labour & Administator) , Service sector (mainly Teacher, Doctors, Official job, ministerial Person , Exesicutive officer etc).This pares scan the ST people are important part in West Bengal…India ….World.


AN ASSESSMENT OF THE PRIMARY HEALTH CARE SERVICES AND UTILIZATION IN IGABI LOCAL GOVERNMENT AREA OF KADUNA STATE[]


This paper presents finding on the assessment of the primary health care services and utilization of existing health care services in Igabi Local Government Area (LGA). The aim of study is to assess the impact of PHC services and utilization in Igabi Local Government Area of Kaduna state. Data from the study was derived from the administration of a structured Questionnaire, Focus group discussion and data from Hospital records. A total of 516 questionnaires representing 0.12 percent of the entire population were administered with the help of some research assistants. A total of 435 questionnaires were used for analysis which was carried out through the use of computer software, SPSS version 9, entry and cleaning. This indicates a sources rate of 84.3 percent. The result represents their interaction with one another and their influences on the impact of PHC delivery system. The finding also reveals that 52.2percent of the respondents have PHC centres in their communities while a significant proportion of the respondents (47.8 percent) indicate that they have no PHC centres.


Calculating the Global Person Generated Index to identify the Impacts of Remittances on the wellbeing of families left behind by migrants[]


Remittances play the role of second largest source of foreign export earnings to Sri Lanka where the 60% of this is from Middle East countries where the majority of domestic Sri Lankan workers are employed. With the main objective of calculating the Global Person Generated Index (GPGI) to identifying the impacts of remittances on the wellbeing of left behind families by migrants a field survey was carried out with 60 Sampath Bank remittance beneficiaries. They were selected from simple random sampling, whose migrants were under the unskilled and housemaid category at Wattala area, covering three GN divsions, Hekitta, Hadala, Hunupitiya. The data collection was done through a semi structured questionnaire as well as using secondary sources. It was found that the flow of remittances will increase in five years ahead but the remittance inflow from Middle East countries will be declined in an decreasing rate (-1.54). Results of the regression analysis shows that perception towards the act of migration depends on, gender (0.743), duration of migration (– 0.0551) and salary of the migrant (0.0227). Global Person Generated Index (GPGI) was used for the assessment of wellbeing of families left behind by the migrants. Results depicts that love, affection and family are the main concerning areas of the lives of migrant left behind families (accounting 23% and13% respectively) followed by several other factors. Further it also shows that they have still not reached the necessity levels with respect to the areas (obtaining minus values for GPGI) of family, children, debt settlement, employment and accommodation. As per the overall view whatever the peoples’ perception towards the migrants and whatever notifications and respects we citizens are paying towards these migrants and not only that how far the government is happy/satisfied due to these enormous retrieval of remittances by recovering the BOPs, the actual owners of those remittances or their beloved family members are still struggling to find out the love, affection and money from remittances (as denoted by the minus value for the difference in ranking for the GPGI) as well as to be well or to reach the required necessity levels in certain other crucial areas of their lives.


Effects of leadership influence on labour management relations: case study of Ebonyi State University, southeastern Nigeria[]


This work identifies the causes of inefficiency and the challenges of leadership influence on labour management relations with case study of Ebonyi State University (EBSU), Nigeria. In the study, descriptive survey design was adopted. The research was carried out on a randomly selected sample of 678 teaching staff and labour union members of EBSU. Data collected for the study were analyzed using simple percentage and Analysis of Variance (ANOVA). Findings from this study indicate that there is a significant effect of leadership influence on labour management relations. It shows a significant effect of labour leadership influence on the management of trade unions like the Academic Staff Union of Universities (ASUU), Non-Academic Staff Union (NASU), and the Senior Staff Association of Nigeria Universities (SSANU) in the case study. The paper therefore recommends that the management of labour unions in state-owned universities in developing countries should be detached from the influence of the government and the university principal officers. Labour unions should be allowed to operate as a single entity representing and protecting the interest of their members devoid of unnecessary influence by the university management. We infer that labour management relations in state-owned institutions in the region has been politicized on the ground of tribe (ethnic consciousness), religion, sex, and interest sharing among various groups within the management team and this attitude should be discouraged.


MEMORY ENHANCED SMART ANTENNAS FOR Wireless COMMUNICATION[]


The paper focuses on the interaction and integration of several critical components of a mobile communication network using smart-antenna systems. This wireless network is composed of communicating nodes that are mobile, and its topology is continuously changing. One of the central motivations for this work comes from the observed dependence of the overall network throughput on the design of the adaptive antenna system and its underlying signal processing algorithms. In the framework of control methods for adaptive phased-arrays, this paper deals with complex communication scenarios by considering a memory-enhanced cooperative algorithm. Compared to existing approaches where far-field interferences are taken into account, the proposed analysis considers a more realistic situation where the jamming sources are located either in the near-field or in the far-field of the receiving antenna.


Lean Improvements to Passenger Departure Flow in Abu Dhabi Airport: Focus on Data from the Check-in Element[]


This is the second paper of three which concerns improving Passenger Departure Flow. The main aim of this paper is provide a summary of the research results, which includes both the reporting of empirical data collected at the Airport and the results obtained from simulation of existing flow for passanger departure process. The large quantity of data means this paper focuses on reporting data for the economy check-in element only. The project led towards development of rules for process of improvement for the entire departure process and explored the benefits of using the Lean philosophy for improving a range of airport processes. Airport processes are completely different than the manufacturing and other service sectors due to the complex interlinking between different stake holders such as airline regulations, national/international law etc.


Microenterprise Owners: Chanllenges with Initialization, Growth, and Success[]


The vitality of any community rests on its entrepreneurs; therefore, understanding the barriers that impede microenterprise initialization and growth is essential. This phenomenological study explored the coping strategies of African American business owners related to business growth and operation in a southeast Virginian city. Two theories framed this study: the resource-based theory and the disadvantage theory of entrepreneurship. Twenty microenterprise owners who had active businesses participated in this study. These microenterprise owners responded to semistructured questions and shared their experiences in face-to-face interviews. Data codification and thematic reduction occurred within qualitative data analysis software. Emergent themes included (a) the effects of barriers on microentrepreneurs, (b) the influences of regulatory agencies on microenterprises, (c) entrepreneurial resources required for success, and (d) agency adaptation to entrepreneurial needs. Two invariant themes emerged from the data; these themes were the importance of location and the availability of a quality workforce.


Study of double layer wire mesh ferro cement plate using neutron imaging technique[]


Neutron radiography is an imaging technique for visualizing the internal structure of an object by measuring the neutron flax passing through this object in two dimensions. This technique has found more and more applications. In the present study an attempt is made to observe the homogeneity, porosity/voids, initial rate of absorption (IRA) and water absorption behavior of double layer wire mesh (DLWM) reinforced Ferro cement plate. The outcomes of this study prove that the homogeneity of the DLWM Ferro cement is almost in regular manner, although contains large voids/ porosity but fewer amount. Water absorption rate is poorer than the initial rate of absorption. It also complies with the IRA measurement of the sample. The consistent measurements have carried out by determining the gray values/neutron intensity ratio values of the respective neutron radiographic images of the sample at dry and different wet conditions. The objective of this study is to improve the more effective use of Ferro cement plate as a construction material especially as water reservoirs, sculptures, and roofs and also this would further lead to an “eco-friendly” low cost housing without any loss of structural integrity.


NIGERIAN WOMEN’S PERCEPTION AND RESPONSES TO GENDER BASED NOLLYWOOD MOVIES: A STUDY OF WOMEN IN SOUTH EAST, NIGERIA[]


From few recent reception studies, female audiences of Nollywood movies differently receive their portrayals therein, some defining them as stereotypic and unrealistic, thereby under representing and misrepresenting the female gender. Reception studies conducted within the western Nigeria, weighed so heavily on literate receivers such as lecturers, students and Nollywood stars but considering also the effect the patriarchal Igbo customs could have on how women receive their identities, this work is a more broadened reception study of the entire women from different socio cultural backgrounds in south eastern Nigeria and sought to determine how and in what ways, these greater number of women, especially those in rural communities, negotiate or perhaps either reject or accept their identities as given in Nollywood. A mixed method of ‘Survey’ and ‘Focus Group Discussion’, were employed whereas the ‘Cultivation’ and ‘Deconstruction’ theories served as the reception frameworks to couch these reception.


GEOSPATIAL MODELING AND MULTI TEMPORAL ANALYSIS OF URBAN DEVELOPMENT TRENDS IN WARRI TOWN DELTA STATE, NIGERIA[]


This paper examines the use of GIS and Remote Sensing in geospatial modeling and multi temporal analysis of urban development in Warri town from 1987 to 2013. Thus the study is to carry out a geospatial modeling and multi-temporal analysis of development trends, thereby detecting the changes that have taken place between these periods. Three Landsat images, Landsat 5TM (1987), Landsat 7ETM+ (2002) and Landsat 8 OLI (2013) were acquired, classified and change detection analysis was performed to determine the multi-temporal urban changes between the years. The result indicated a rapid growth in built-up area between 1987 and 2013. Built up area had 155590200m² in 1987, then increased to an area of 249725653.3 m² in 2002, then increased to an area of 334934100m² in 2013 indicating a stage of modern industrialization and urbanization. It was also observed from the trend of change, that built up area had an annual rate of change of 1.55% from 1987 to 2002 and 1.81% from 2002 to 2013 and may likely continue to increase gradually further down the years. It was further recommended that studies on the impact of urban development in be carried out in order to determine effects of rapid urbanization in Warri town and that Land Consumption Rate and Land Absorption Coefficient should be incorporated in future research studies since built up area expansions is a combination of anthropogenic activities and one that also affects the other classes (socially and economically).
