COMPARATIVE ANALYSIS ON THE MECHANICAL PROPERTIES OF A METAL-MATRIX COMPOSITE (MMC) REINFORCED WITH PALM KERNEL/PERIWINKLE SHELL ASH [PDF]
IYASELE, Edgar Omondiale The research presents the comparative analysis on the mechanical properties of a Metal-Matrix Composite (MMC) reinforced with palm kernel/periwinkle shell ash for automobile applications. Four specimens consisting of Sample A (300g of aluminum), Sample B (295% of aluminium, and 5% of Silicon Carbide [SiC]), Sample C (290% of aluminium, 5% of Silicon Carbide and 5% of palm kernel [PKSA]) and (285% of aluminium, 5% of Silicon Carbide, 5% of palm kernel and 5% of periwinkle shell ash [PSA]) were produced using stir casting method and their mechanical properties (hardness, tensile strength, microstructure) were evaluated. Particle reinforced Al-MMC can be synthesized stir- casting method. Commercially solid aluminium (up to 99.1% purity) served as the matrix while Silicon carbide, palm kernel shell ash and periwinkle shell ash particle were used as the reinforcements. It involved the melting of the aluminium solid followed by adding the reinforced particles for different weight percent to the melt. The microstructural examinations revealed a uniform distribution of the reinforcements. From the analysis of results obtained, we found that the ultimate tensile strength of aluminum based metal matrix composite decreased as we added the weight fraction of SiC; increased as we added the weight fraction of PKSA and decreased as we added the weight fraction of PSA particles. The elastic modulus of aluminum based metal matrix composite decreased as we added the weight fraction of SiC, increased as we added the weight fraction of PKSA and decreased as we added the weight fraction of PSA particles. The hardness of aluminum based metal matrix composite increased as we added the weight fraction of SiC, and decreased as we added the weight fraction of PKSA and increase as you add the weight fraction of PSA particles. The ductility of aluminum based metal matrix composite decreased as we added the weight fraction of SiC, and increased as we added the weight fraction of PKSA and PSA. Conclusively, with the observations made on the mechanical properties of pure Aluminium metal reinforced with SiC, PKSA and PSA, SiC and PKSA have a better mechanical properties if used as reinforcement material in Aluminium metal matrix composite. Thus, this work has provided ways of converting commercial wastes, especially palm kernel shell and periwinkle shell which are posing environmental problems, to useful substances.

Experimental Investigation of the Effect of Cutting Parameters on Cutting Temperature Using RSM and ANN in Turning AISI 1040 [PDF]
Rifat Ahasan Siddique, Farhana Dilwar, Md. Rezaul KarimIn the present research, experimental investigation is done to identify the impact of cutting parameters (feed rate, cutting speed and depth of cut) on the cutting temperature in turning of AISI 1040 by using Response Surface Methodology (RSM) and Artificial Neural Network (ANN). Response surface methodology (RSM) is used to design the experimental layout consisting of 16 datasets using Central Composite Design (CCD). Significance of the cutting parameters is determined utilizing statistical analysis of variance (ANOVA) which indicates that all the three cutting parameters have noteworthy impact on the cutting temperature. The 3D response graphs present cutting temperature is increased with the increase of feed rate, cutting speed and depth of cut. Desirability Function Analysis (DFA) is employed to decide optimal values of cutting parameters. It is suggested from DFA that minimum temperature is obtained at lower feed rate (0.100 mm/rev), lower cutting speed (62.172 m/min) and lower depth of cut (0.200 mm). Afterward, main effects plot is analyzed to show the variation of response with the three input variables and the result found from main effects plot is almost coherent to the results found from 3D plots and Desirability Function Analysis (DFA). The predicted results using ANN indicate good agreement between the predicted values and experimental values. The R² value for model θ is noticed to be 0.99081. The deviation between experimental values, RSM predicted values and ANN predicted values is very minimum which presents the efficacy of the proposed RSM and ANN model. But MAPE for RSM is 0.001336 and ANN is 0.006245 which evidently indicates that the prediction capabilities of RSM model are better as compared to the ANN models for this experiment.
IMPACT OF THE INTERACTION TRACES CONTEXTUALIZATION ON THE PERFORMANCE OF TRACES-BASED SYSTEMS [PDF]
Macaire NgomoThe new dimension of collaboration, brought by collaborative platforms, induces a new management approach that must consider methods of observation and behaviour analysis as a means to optimize the productivity of organizations. From this point of view, although they have evolved a lot in recent years, especially with social networks, the contextualization of digital interaction traces within collaborative platforms remains a major topic for the performance of data operating systems. The work that we present in this paper is part of the projects of implementation of collaborative and learning management systems, collaborative work and services, in a IT Environment for Human Learning vision (IEHL), more precisely, on the intelligent architectures of the platforms aiming at a better or-ganization around the concept of unity of interaction which introduces a sort of contextualization of the collected digi-tal traces. The resolution of the problem of the personalization of IEHL is moreover essentially dependent on the ability to produce relevant and exploitable digital traces of the individual or collective activity of the users (learners in particular), who interact with an IEHL. In the present work, we are interested in the organization of collaborative tools and its impact on the performance of digital interaction traces analysis mechanisms. Our study is based on the results of observation and analysis of human interactions within collaborative platforms, in particular those developed within the framework of our projects.

STATUS OF LIPID PROFILE, ANTIOXIDANTS AND LIPID PEROXIDATION IN CORONARY ARTERY DISEASED PATIENTS IN SOUTH WESTERN NIGERIA [PDF]
I. Akinlua, M. F. Asaolu Cardiovascular disease is a major cause of death with coronary artery or heart disease being the single most important cause of death worldwide. Oxidative stress and inflammation are cooperative events involved in the development of atherosclerosis which is the underline factor in coronary artery disease progression. This study was designed to investigate plasma lipid profile namely total cholesterol (TC), low density lipoprotein cholesterol (LDLc), high density lipoprotein cholesterol (HDLc) and triglycerides (TG), plasma antioxidants; namely Vitamin C and E, Catalase, Superoxide dismutase and Glutathione peroxidise in coronary artery diseased patients. Plasma malondialdehyde(MDA) was also determined in these patients. A total of 200 angiographically diagnosed coronary artery duseased patients of both sexes attending various teaching hospitals, medical centers and general hospitals across Southwestern Nigeria were screened for this study. Significant risk factors such as cigarette and diabetes were excluded from the study. They were matched with equal number of normal subjects. The result of the study shows a significant increase in the plasma level of both total cholesterol and LDL cholesterol in coronary artery diseased patients while the plasma level of high density lipoprotein cholesterol was significantly lowered in these patients when compared with the control subjects. Similarly the plasma level of MDA in these patients was significantly higher than the control subjects. The result also shows a significant decrease in the plasma level of the various antioxidants considered in these patients when compared with the control subjects.
REVIEW ON PARALLEL IMPLEMENTATION OF PRINCIPAL COMPONENT ANALYSIS FOR FACE RECOGNITION USING MPI AND OPENMP [PDF]
Mr. Namdev M. Sawant,Mr. Rirandra A. Dhotre,Mr. Pravin P.Botre PCA is a statistical approach that analysis a data table in which observations are describes by several inter correlated quantitative dependent variables. It uses mathematical principals to transform number of possibly correlated variable into a smaller number of variable called principal component. One of compute intensive application of PCA is face recognition. In PCA, every image in the training set is represented as a linear combination of weighted eigenvectors called eigenfaces. These eigenvectors are obtained from covariance matrix of a training image set. The weights are found out after selecting a set of most relevant eigenfaces. Recognition is performed by projecting a test image onto the subspace spanned by the eigenfaces and then classification is done by measuring minimum Euclidean distance. Some of the modules such as Covariance Module, Jacobi Module, Eigenface Module required more time for execution. These modules will be made parallel with the help of parallel programming models such as OpenMP and MPI and performance & evaluation will be made between sequential and parallel implementation.
THE EXPRESSION PROFILING OF ALDH3A1, CD44, CD133 AND TNFRSF9 IN HUMAN BREAST CANCER STEM CELLS [PDF]
SHADIA S. ALHAMD Real-time PCR has been used to quantify the gene expression of selected genes to compare among different isolated cancer stem cells. These genes were detected are linked with the reproduction, cell apoptosis and chemotherapy. These genes used as markers to investigate cancer stem cells and as target therapy. In addition, to identify the expression pathways of some genes which related with BCSCs that identified to contribute to tumourgenesis as well as drugs resistance. The expression of these genes will be used to isolate BCSCs from tumour samples or breast cell lines which based on CD44+/CD24-/low, which considers as a crucial marker or ALDH+ phenotypes. Because this isolation will help to analyse the molecular mechanisms which present by self-renewed and differentiation of cells. There is evidence proposed that the isolation of BCSCs will allow the discovery of target therapy and this will remove the mass tumour and breast cancer by using these genes which will up-regulate or down-regulated as it was conducted by several papers. In addition, to clarify the expression of selected genes markers in the isolated BCSCs and the tumourgenicity that is a phenomenon degenerated by a subpopulation of the tumour cell which known as cancer stem cells. In this investigation that aimed to isolate BCSCs from the bulk of breast cancer cell. This extraction of breast cancer stem cells was identified by using sphere formation assay. The total RNA was extracted from the isolated breast cancer stem cell in order to detect the expression of novel markers such as;(ALDH3A1) Aldehyde dehydrogenase 3family member A1, the main cancer stem markers CD44,CD133 and finally tumour necrosis factor receptor super family 9(TNFRSF9) by run Real-Time PCR.In this part of our project, we will look at different genes and their expression profiles that are related to the same cells. These isolated stem cells could be tested to quantify the expression profiles of selected genes CD44, CD133, ALDH3A1 and TNFRSF9 as crucial biomarkers.We investigate cancer stem cells by molecular analysis that includes detection and clarification of the down and up-regulated genes between the strengthened cancer stem cells (spheroid), single and parental cells. Therefore, this isolation allows us to identify the bulk cells to select more specific target therapy.
Isolate and identified cancer stem cells by using MCF7 human breast cancer cell line, using mammospheres formation in two different methods [PDF]
Shadia s. Alhamd Cancer represents one of the most significant challenges facing biological and clinical research. A higher understanding of the theory and mechanism of cancer will allow scientists to develop an active target therapy of cancer diseases. It has been suggested in several studies that a tumour that has been derived from many cells that have the ability to rapidly reproduce many more new cells and increase the tumour. Cancer stem cells are one of these types of cells which have been isolated in different parts of the body such as in the breast, prostate and colon. Breast cancer stem cells (BCSCs) have been shown in several studies to comprise of small parts of cancer cells which lead to an increase the prognosis of breast cancer. This type of tumour cells able to develop tumour generation. The focus of this research will be in breast cancer (BC) which still the main issue of public concerns. As a result of many studies which show that BC remains the popular cancers among women in the world. In China, for example, more than million cases each year. In spite of all the concentration to discover a new, fast diagnosis method and treatment, BC still forms the second causes of death among women in the world. The majority of cancers incidence are belonged to uncontrolled on the rapid growing of the cells.In this project, MCF7 human breast cancer cell line used to isolate cancer stem cells by using mammospheres formation in two different methods.The main target of this work was to isolate cancer stem cells from human breast cancer cell lines and compare with the parental cells, single and cancer stem cells which we have identified by using spheres formation assay.

ENERGY EFFICIENT TASK ASSIGNMENT ALGORITHM FRAMEWORK IN MO-BILE CLOUD COMPUTING [PDF]
Irfan Ali Jamali, Abdullah Lakhan, Dileep Kumar, Abdul Rasheed Mahessar, Rakhsinda lodhi In Mobile Cloud Architecture (MCA) empowers constrained resources mobile devices to execute the complex application with collaborative way. The offloading system is a process in which mobile application can be divided into local execution and cloud execution in order to minimize energy consumption of mobile CPU. However, existing offloading systems do not consider data transfer communication energy while performing mobile offloading system. They have just focused on mobile CPU energy consumption. In this paper, we are investigating the energy consumption mobile CPU and communication energy collaboratively while performing mobile offloading for complex applications. To cope up with the above problem, we have proposed Energy Efficient Task Scheduler (EETS) algorithm, which aim is to determine optimal task execution in offloading system in order to minimize mobile CPU and communication energy. Simulation results show that EETS outperforms as compared to baseline approaches.
Impact of Firm Specific Factors on Profitability of Firms in Food Sector [PDF]
Dr. Amit Jain The aim of this study is to examine the impact of firm specific and macroeconomic factors on profitability of food sec- tor in Pakistan. This study explores the impact of firm specific factors on profitability of companies listed in food sector of Karachi stock market in the presence of food inflation by employing multivariate regression analysis in common ef- fect setting for the period of 2012-2018. The firm specific factors include debt to equity, tangibility, growth and size and macroeconomic factor include food inflation. Findings of study reveal the presence of significant negative relation- ship between size and profitability. However, tangibility, growth of the firm and food inflation are found insignifi- cantly positively related to profitability. Similarly, an insignificant negative relationship is observed between debt to equity ratio of firm and its profitability. Empirical results provide evidence that the profitability of food sector is shaped by firm specific factors and not macroeconomic variables. One important limitation of study is that it only considers one macroeconomic factor i.e. food inflation. In future studies more macroeconomic factors will be explored to examine their impact on profitability of food sector firms. However, this study still provides significant insight about dynamics of profitability in food sector and helps in making optimal decisions of resource allocation in food sector of Pakistani equity market.
FOREIGN DIRECT INVESTMENT AND ITS IMPACT ON ECONOMIC GROWTH OF NIGERIA (1985-2016) [PDF]
Yinka Calvin Ojeleye,Abdulgafar Akinola,Paul Igomu Pius The research is aimed at exploring Foreign Direct Investment and its impact on economic growth of Nigeria. The study covers 31-year period between 1985-2016. Simple ordinary least-square regression model is used to measure the effects and relationships between the independent variable and the dependent variable using E-views 9.0. Foreign Direct Investment (FDI) serve as the independent variable while economic growth as the dependent variable. GDP, exchange rate, inflation rate, unemployment rate, total savings and interest rate were used as proxies for economic growth. Data on FDI, GDP, exchange rate, unemployment rate, savings and interest rate were retrieved from the CBN Annual Statistical Bulletin, World bank Report and National Bureau of Statistics. The stationarity property of a time series data can be examined by conducting unit root test in order to ascertain the stationarity or otherwise of the series variables (Akinola,2016). Augmented Dickey-Fuller (ADF) test due to Dickey and Fuller (1979, 1981), and the Phillip-Perron (PP) due to Phillips (1987) and Phillips and Perron (1988) were used to ensure the stationarity of the time series data i.e dependent and independent variable. The finding showed that there is a strong and positive relationship between FDI and economic growth in Nigeria. The government of Nigeria must put all hands-on desk, formulating policies and necessary reforms to ensure that foreign direct investments are attracted to benefit the populace at large. It also recommended that Institutionalized corruption both in private and public sectors must be fought, if the nation must attract FDI, we must change our ways of doing things.

Cloud Computing Simulation Using CloudSim Toolkits [PDF]
Md. Nadimul Islam Cloud simulation aims to power the next generation data centers and enables application service providers to lease data center capabilities for deploying applications depending on user QoS (Quality of Service) requirements. Cloud Simulation applications have different composition, configuration, and deployment requirements. Quantifying the performance of resource allocation policies and application scheduling algorithms at finer details in Cloud computing environments for different application and service models under varying load, energy performance (power consumption, heat dissipation), and system size is a challenging problem to tackle. in this paper we propose CloudSimulation:an extensible simulation toolkit that enables modeling and simulation of various Cloud Simulation environments. The CloudSim toolkit supports modelling and creation of one or more virtual machines (VMs) on a simulated node of a Data Center, jobs, and their mapping to suitable VMs. It also allows simulation of multiple Data Centers to enable a study on federation and associated policies for migration of VMs for reliability and automatic scaling of applications between user and hosts due to cloudlet.

VULNERABILITY ASSESSMENT OF 2015 FLOOD IN NORTH CENTRAL NIGERIA USING INTEGRATED APPROACH OF HYDROLOGICAL MODEL AND GIS [PDF]
Elijah Adesanya ADEFISAN and Egiku JummaiThe research aimed at designing and implementing a hybrid approach where flood event was simulated by integrating hydrological model HEC-RAS (Hydrological Engineering Centre) with GIS (Geographical Information System) so as to identify and analyse flood prone zones in Lokoja north central Nigeria. The present study developed a hybrid approach in identifying flood risk zones and assessing the extent of impact of the hazard by integrating HEC-RAS and GIS technologies. This GIS-based approach, which allows visualizing and quantifying the results in a spatial format, was applied to Lokoja. 2015 flood event was simulated to expose the extent of the current infrastructure of the area to flooding. A single data entry of river channel geometry and flow into the HEC-RAS computer program is sufficient to model steady flow, unsteady flow, water surface profiles, sediment transport/movable boundary computations, and water quality. In this research, steady flow was simulated along River Niger and flood hazard extends derived using HEC-RAS/HEC-geo RAS. For simulating, first used HEC-geo RAS to define the river channel and extract cross sections from the TIN, then the results of pre-RAS within the steady flow data and the other required data imported to the HEC-RAS for process and ultimately provided the inundation extends of 2015 flood event.The results indicated that hydraulic simulation by integrating HEC-RAS model GIS is effective for various kinds of floodplain managements and the developed methodology was efficient in modelling and visualizing the spatial extent of different month’s scenarios and in determining flooded areas at risk. It was found that changes in water elevations of the River Niger made the downstream areas more at risk. The simulated output is validated by comparing the simulation output with the observed data of 2015 flood event from the National Waterways Authority (NIWA) Lokoja mentions the inundation depth of River Niger as at the time of the flood event to be 37m. The inundation depth level obtained through HEC-RAS simulation of the flooded month to be 35m. The difference in the estimation (which is less by 2m) of the inundation depth level by HEC-RAS simulation could be attributed to the usage of Land use and Digital Elevation Model (DEM) data in the model. As the results yielded by the HEC-RAS model are close to the observed data of 2015 flood, the model can be assumed as valid to perform assessment of flood event for the study area.
INCLUSIVE ROLES OF EDUCATIONAL MANAGEMENT IN STIMULATING ENTREPRENEURSHIP EDUCATION FOR A SELF-RELIANT ECONOMY [PDF]
BASHAR, Sa'adu Isa, YUSUF, Barau IsaNo nation will ever develop and have a self-reliant economy if its human capitals are not entrepreneurially innovative, creative and productive. To achieve this, schools are meant to be the primary educational environments through which skills and other entrepreneurial activities are being imparted to the teeming students. To this end, the school leadership needs to intensify efforts in exhibiting its basic roles in fostering entrepreneurship education. Based on this premise, the paper came to justify the basic roles that an educational management can play towards actualizing entrepreneurship education in educational institution in an attempt to promote self-reliance among the students for national development in Nigeria. After making a conceptual clarification of the major concepts, the paper outlined and discussed the major roles which among others include: providing advocacy awareness to both parents and students, providing positive leadership, providing technical assistance and establishing favorable linkages with other sister institutions. Similarly, the paper recommends the need for extending entrepreneurship education beyond educational institutions, government at all levels need to make fund available to the educational managers for shouldering the matters arising concerning the entrepreneurial demands of the schools as there is also the need to establish monitoring and inspection departments for carrying out monitoring and supervision functions of the entrepreneurship education and programmes in the schools. This will boost the Nigeria’s economy to a highest level of development.

SUITABILITY OF AGRICULTURAL BY-PRODUCTS IN NIGERIA AS PARTIAL REPLACEMENT TO CEMENT IN INFRASTRUCTURAL PROJECTS: A REVIEW [PDF]
Ugwuanyi, D.C, Onuamah, P.N.High cost of Portland cement had hindered the availability of affordable infrastructure in materials as alternative relying on locally available and otherwise wastes from agricultural produce. Utilization of agricultural by-products as partial replacement to cement will reduce their environmental challenges and increase the affordability of cement based infrastructures since cement constitute a major proportion of the costs. Most agricultural by-product ashes have been found to improve the strength properties of cement based material especially at their later ages. The durability of cement based materials such as chloride ion permeability, porosity, water absorption and thermal conductivity is substantially improved. Nigerian agricultural sector is still dominated by subsistence farming, however, rice husk and saw dust could be available in commercial quantity in rice and timber mills respectively.

A.O. Donald, M.A Hassan, S. Hamza, E. Garba, D.K. Dangtim and M. MamadouIn the present work, an effort has been made to develop a hybrid aluminium matrix composite for automobile piston application using locally available material: Al 6061 alloy was selected as the matrix material while carbonized coconut shell particles (CCNSp) and SiCp as reinforcement. Composite were prepared using powder metallurgy technique with 0, 2, 4, 6, 8, and 10 wt % of reinforcement. The requisite mixtures were obtained using high energy mixer and loaded into a steel mould and compressed using a Compac hydraulic press of 500kN capacity to obtain the green compacts. The green compacts were carefully ejected and sintered in a muffle furnace at 527oC for 1hour. Mechanical and thermal properties were investigated. For green compacts, a range of 66.17-107Hv, was obtained for hardness, while for sintered compacts the values obtained are 72.57-105.47Hv, 172.25-207.61MN/m2 and 2.2136-2.5804x10-5K-1 for hardness, tensile strength and coefficient of thermal expansion respectively. Microstructural examination of developed composites materials reveals that the reinforcement’s particles were uniformly distributed in the base matrix and that bonding took place between the base matrix and reinforcements after sintering.

IMPACT OF RTEMINTANCE ONE ECONOMIC GROWTH AND DEVELOPMENT IN REPUBLIC OF MACEDONIA [PDF]
PhD Rametulla Ferati,PhD Candidat Nedime Sallai,PhD Hasim DeariFor more than half a century, there has been heated debate on the sources of economic growth in developing countries. Factors perceived growth are ranked by overwork for capital investment and technological changes, foreign aid, foreign direct investment, investment in human capital, increasing the return on investment in new ideas for research and development. Positive or negative impacts outlined above on traditional sources of economic growth have been documented in scientific research. Other researchers have also considered the importance of institutional factors such as the role of political freedom, political instability and accountability in economic growth and development.Despite the increasing importance of remittances in total international capital flows, however, direct or indirect ratio between remittances and development and economic growth has not been studied adequately. This study examines the impact of private transfers in economic development using timely data spanning the period 2005-2015 in the Republic of Macedonia. According to empirical results, private transfers have stimulated economic development in countries where financial systems are less developed, offering an alternative way to finance investment and to help the country's liquidity.
ROLE OF LEGAL FRAMEWORK FOR THE PROTECTION OF FEMALES IN CAUSING DESPAIR IN UNMARRIED GIRLS NABILA SARWAR, REHAN ULLAH AND ASAD ULLAH [PDF]
Nabila Sarwar, Rehan Ullah and Asad UllahThe present study was conducted with objective to determine the causes of despair in unmarried girls. A sample size 159 respondents out of 264 was selected through random sampling procedure from three Mohallahs of Union Council Jahngrha, district Abbotabad, Khyber Pakhtunkhwa, Pakistan. The conceptual framework of the study comprised of legal framework for the protection of females as independent variable and causes of despair in unmarried girls as dependent variable. Chi-square test was used to find out association among study variables. The study found that a significant association was established between despair and ensuring girl’s rights to education to achieve their social potential (p=0.000) and the legal measures of domestic violence achieving its objective completely (p=0.008). Awareness rising among masses through use of mass media, local political and religious leadership regarding religious and legal rights and status of women so that view of marriage and dowry as a capital transfer is publically negated, devising policies that can make it easy for poor and middle class females to access judiciary, minimize domestic violence through implementation of law, enhancing female learning and strengthening moral base of marriage and family to measure morality instead of economic benefits in mate selection were recommendations in light of study findings.
FOREST COVER CHANGE IN GODAWARI KHOLA SUB- WATERSHED, LALITPUR [PDF]
Prerana MishraThe land-use/land-cover (LULC) pattern of a region is an outcome of natural and anthropogenic process. Land-use/land-cover change has become a central component of current strategies in managing natural resources and monitoring environmental changes. The present study was carried out with an integrated approach using Remote Sensing and GIS techniques for land cover change detection. Landsat TM of 1989 and 2011 and ETM+of 1999 imagery were used to evaluate forest cover dynamics during 1989 to 2011 in the Godawarikhola Subwatershed, Lalitpur, Nepal. The aims of the study were to quantify and map the spatio-temporal pattern of forest cover change in term of landuse changes between1989-2011 and to explore the proximate cause behind those processes. Supervised classification was used to prepare landuse maps using the maximum likelihood algorithm. Image classification was carried out by emphasizing six main categories. Ground verification was done in February, 2014.The study revealed that there is decrease in forest cover from 1989 to 2011. In 1989 forest coverage area was 80%, where in 1999 it was 53.9% and in 2011 it was 50.7%. This shows that there is a rapid decrease in forest cover from 1989 to 2011 with the rate of changes 16.48% and 9.6% from 1999 to 1999 and 1999 to 2011 respectively. This compensates to increase in agricultural area where in 1989 its coverage was 11.5% of the total study area, which increased to 27.9% in 1999 and in 2011 to 36.66%. The overall accuracy was 78% for both year maps.For a clear comparison between the landuse/ landcover changes in total and in a managed community forest, Diyale Dada community forest having total area of 224.71 was selected. And accordingly, its landuse/ landcover map was developed using GIS. During 20 years period from 1988 to 2009, forest area is increased by 4.80%. The cultivation land is decreased by 14.26 %. The increment of shrub land is the highest and indicated that the cultivated land has transformed to shrub and forest land. The status of Diyale Danda Community Forest shows the total species richness of 26 in which tree density was found to be 1785 individuals per hectare.
INFLUENCE OF ONLINE ADVERTISING ON CONSUMER BRAND AWARENESS AND PATRONAGE OF FINANCIAL INSTITUTIONS IN ENUGU: A STUDY OF UNITED BANK FOR AFRICA (UBA) [PDF]
Okolo, Victor O, Okafor, Jones N, Obikeze, Chinedum O,Nduka, ChinedumInfluence of online advertising on consumer brand awareness and patronage of United Bank for Africa (UBA) was investigated. Most consumers have not adequately adopted online transaction even when they are aware of its existence. The extent online advertising influences consumer brand awareness, the extent online advertising influences consumer purchase behaviour and the extent online advertising influences consumer brand recall of UBA products were the research objectives. The scope of the study is the influence of online advertising in UBA Enugu. Population of the study is all customers of 5 branches of UBA who are educated and are connected to the internet. Sample size was determined using Freund and Williams’s method as the population is indefinite. Purposive sampling technique was adopted and survey method was used to gather primary data using questionnaire instrument. Content validity was conducted to sort out for consistency of the questionnaire and reliability was achieved using Cronbach’s alpha and a value of 0.890 was arrived at. Findings revealed online advertising significantly influences customer brand awareness of UBA products. Also, it was discovered that online advertising has no significant influence on consumer purchase behaviour. And also, online advertising has no significant influence on consumer bran recall of UBA products. The study recommends that the banks should design their online advertising in attractive texts, images and even videos to create better awareness of their various products. Bank marketing executives should persuade customers on one-to-one bases to adopt the online banking transactions. Also, financial institutions who haven’t adopted online advertising must key into it to foster consumer brand awareness and patronage.

The study recommended: harmonizing existing laws and regulations with the UNLP 2013; to further decentralize land rights administration and delivery of secure land rights by engaging and integrating customary land institutions and practices as required by the 2013 to allow for further local participation; divorce politics from administration.
RESOURCE ALLOCATION AS A STRATEGY FOR POVERTY ALLEVIATION IN UGANDA: A CASE OF IGARA AND SHEEMA COUNTIES IN BUSHENYI DISTRICT [PDF]
David Mugisha BegumyaThis study was designed to explore resource allocation as a strategy for poverty alleviation using the counties of Igara and Sheema in Bushenyi District as a study case. The study targeted 382 residents, 52 officials; 40 development partners (Non Governmental Organizations) and 12 District sector heads. A research design was employed. The findings revealed that the policies used during resource allocation include the Local Government Act 1997, Universal Primary Education, Primary Health Care, National Agricultural Advisory Services, The National Budget and Operations Maintenance Policy. It was concluded that there exists resource allocation and it has a relationship with poverty alleviation. Also the conduct of some officials involved in resource allocation is unprofessional. To enable informed decisions in resource allocation, the paper recommends that extensive studies be conducted to determine the nature of poverty and consultations made with locals in determining policy. Corrupt officials in the process of resource allocation should be identified and disciplined to deter others.

Ejiko Samuel Omojola, Akerele Olalekan Victor and Filani Abidemi OreoluwaEffective Automobile layout is of paramount importance for setting up workshop facilities and equipment in attaining minimum turnaround time. It also brings about increment in productivity and profitability. The Federal polytechnic Ado-Ekiti Automobile workshop does not meet with the standard workshop layout; this implies the need to develop an improved integrated workshop layout. In achieving the improved layout, standard workshop within the country were visited (most especially Akure and Ado-Ekiti), literatures were consulted and questionnaires were administer and considered. A new layout model was developed in accordance with standard workshop which will give room for effective automobile service delivery. The management needs to invest more in the procurement of up to date machines and equipment, employment of more man power with different specializations regarding automobile services and implement the application of the developed layout model.
EFFECTS OF LEAD ON SEED GERMINATION AND SEEDLING GROWTH OF WHEAT (TRITICUM AESTIVUM) L. [PDF]
SAHAR MEHBOOB,M. ZAFAR IQBAL,MUHAMMAD SHAFIQ,MUHAMMAD KABIR AND ZIA-UR-REHMAN FAROOQILead is one of the highly toxic heavy metal and being a dangerous environmental pollutant and exerts harmful effects on plant growth. The effects of different concentrations (0, 20, 40, 60, 80, 100 ppm) of lead on seed germination and seedling growth performance of wheat (Triticum aestivum) as compared to control was studied. Lead treatment in the form of lead acetate at 100 ppm completely inhibited the seed germination and seedling growth of T. aestivum as compared to control. Lead treatment at 40 ppm produce significant (p < 0.05) reduction in seed germination while lead treatment at 20 ppm concentration produced significant reduction in shoot length as compared to control. Root growth is an important growth variable and found greatly reduced at different concentrations of lead treatment. The treatment of lead at 20 ppm produced significant (p< 0.05) reduction in seedling dry weight of T. aestivum as compared to control. However, increase in concentration of lead treatment at 80 ppm was found sufficient to cause significant reductions in seedling dry weight of T. aestivum as compared with control.The seedlings of T. aestivum were also tested for percentage of tolerance to lead. The results showed that T. aestivum has high tolerance to lead at 20 ppm (92.50%) and lowest at 80 ppm (64.50%) of lead. T. aestivum seedlings showed better percentage of tolerance (73.25 %) to lead at 60 ppm. The seedlings of T. aestivum were tested for the establishment of seedling vigor index (SVI) to different level of lead treatment. The results showed that T. aestivum has greater seedling vigor index was (1893) to lead at 0 ppm and lowest (302) at 80 ppm of lead. T. aestivum seedlings showed moderate SVI (1586) at 20 ppm lead treatment. T. aestivum showed better SVI (847) to lead treatment at 60 ppm.

EFFECT OF GREEN SUPPLY CHAIN MANAGEMENT PRACTICES ON THE PERFORMANCE OF MANUFACTURING FIRMS IN KENYA [PDF]
Achuora John Due to the perceived performance implications of GSCM, research in this area has grown in recent years. However, the literature is limited on the performance implications of GSCM on firms especially in the developing countries. Thus, the literature has yet to furnish an accepted explanation on whether a positive relationship exists between Green Supply Chain Management (GSCM) Practices and firm performance. This dissertation has responded to this challenge through the exploration of the consequences of GSCM practices on the performance of manufacturing firms in Kenya. The study was guided by the following objectives: to establish the effect of green procurement on the performance of the manufacturing firms, to establish the effect of green manufacturing on the performance of the manufacturing firms, to establish the influence of green distribution on the performance of the manufacturing firms, to establish the effect of environmentally-oriented reverse logistics on the performance of the manufacturing firms and to establish the moderating effect of supply chain ecocentricity on the relationship between green supply chain practices and the performance of manufacturing firms. The study is built on the theoretical framework of the ecological modernization, resource based view, stakeholder, corporate environmental responsibility and social network and investigated four potentially important dimensions of GSCM and how such dimensions, in turn, shape firm performance. Specifically, a theoretical model was developed and tested on the basis of the hypothesized relationships among the four dimensions of GSCM, Supply Chain Ecocentricity as the moderating factor, and how these dimensions relate to firm performance. Significant results and good fit indices tested with multiple regression model and confirmatory structural model. Positivism paradigm approach, mixed method research and the cross-sectional survey research design were adopted in this study. The target population for this study were the manufacturing firms in Kenya. The study population were the manufacturing firms registered as members of the Kenya Association of Manufacturers as at 2014 and the respondents were the designated heads of supply chain management of these firms. A semi- structured questionnaire was administered through the e-mail survey. Secondary data was obtained from both published and unpublished records. The questionnaire was tested for validity and reliability. Both quantitative and qualitative techniques were used to analyse the data with the assistance of SPSS software program version 22, Ms-Excel for window 8 and Analysis of Moment Structures (AMOS) version 18. Supply chain ecocentricity moderating effect was tested by F-test. The study found that Green Procurement, Green Manufacturing, Green Distribution and Environmentally Oriented Reverse Logistics were individually predictors of firm performance with Green Manufacturing being the most significant predictor. In contrast, the study established that Supply Chain Ecocentricity is not a moderating factor in the study. The results support the current theories related to the study. Consequently, this study provides firms’ managers with insights of how firms can develop a competitive edge through the implementation of GSCMPs. This study therefore, recommends that factors associated with Green Supply Chain Management need to be embraced by firms in their performance strategic plans as they have significant impact on performance. Further, the government should adopt a mixed policy on ecological management by focusing on both statutory regulations and internal directives with direct impact on firm performance such as tax rebate on eco-equipment and processes. The study concludes that greening initiatives within the manufacturing firms supply chain management has the potential of positively influencing their performance in terms of cost reduction and environmental product differentiation.

In proposed framework AES Symmetric Cryptography algorithm and LSB of Image Steganography algorithm are used to enhance the current security short fall of M- Banking with minimum cost. In this approach bank encrypted and hidden transaction data in the Image to send it to bank’s customer and the customer should decode and decrypt to get the original data.
TECHNOLOGY FOR DEVELOPING ECO-FRIENDLY COLORING MATERIAL SUITABLE FOR FIBRE AND HANDICRAFT PRODUCTS [PDF]
G.Athinarayanan, A.J.A.Ranjitsingh , Dhasarathan , C.PadmalathaAs synthetic colorants used in natural fibre products, children’s toys and handicraft products cause toxicity to the consumers. To overcome this issue it is imperative to find out safe eco -friendly dyes from natural resources. With this intension in the present study seven types of colors, violet indigo, blue, green, yellow, orange and red yielding plant sources were identified. The color yielding components in the plants were separated. The color imparting extracts were tested in several handicraft products and it was found highly beneficial. Using the barks of the tree Caesalpinia sappan, flowers of the plant Nyctanthes arbortristis, barks of Rubia cordifolia, flowers of Michelia champaca, cutch of Acacia catechu and rhizomes of Curcuma longa., the dyes prepared from these plants and were tested for their fastness properties . Dye preparation technology was identified for their application in a commercial products.
EFFECT OF BIODEGRADED PLASTIC BLENDS ON THE GROWTH-RATE OF SOY BEAN PLANTS [PDF]
Ifeoma P. OragwuThe effect of biodegraded low density polyethylene(LDPE) blends on the growth rate of soy bean plants was studied under the agricultural environmental conditions. Corn (Zea Mayz) starch which is a bio-filler was extracted, characterized, and incorporated into the synthetic low density polyethylene pellets, to initiate it’s decomposition. The starch/plastic compatibility was improved by addition of a coupling agent(maleic anhydride- g-polyethylene), injection molded and extruded as sheets. Microbiological analysis of the soil sample was carried out to ascertain it’s inhabitants. Some mechanical, water absorption, percentage weight-loss, and physical tests were carried out on the blended plastic blends for a period of 180 days before the plantation of the soya-bean seeds. The growth rate of the soya bean plants were monitored after germination at 7 days intervals for a period of 120 days. The growth rate of the plants was observed to increase, with the increase in starch contents, extent of decomposition and soil burial periods.
Fortification Of Soybean Flour On Catfish Nugget Preference Level [PDF]
Iis Risnawati, Evi Liviawaty, Rusky Intan Pratama and Iis RostiniThis research aims to determine the percentage of soybean flour as a source of vegetable protein in catfish nuggets prefered by panelists. The method used was experimental method with the comparison of soybean and tapioca by 0%: 100%, 10%: 90%, 15%: 85%, 20%: 80% and 25%: 75% based on the amount of flour used. The parameters observed were made to the preferences level (the appearance, aroma, texture and taste characteristics performed by semi-trained panelists), folding test, moisture content, ash content, protein content and fat content in catfish nuggets. The results showed that 15% : 85% comparison of soybean and tapioca flour was the most preferred treatment by panelists compared to other treatments with 8.0 mean value of appearance, 7.6 aroma value, 8.1 texture value, 8.0 taste value, and proximate test results for moisture content is 67.50%, 1.93% ash content, 15.78% protein content and 7.57% fat content.
THE EVALUATION OF THE NATIONAL POLICY ON GENDER IN BASIC EDUCATION IN NIGERIA [PDF]
OLASUNKANMI OLUSOGO OLAGUNJUEducation is an instrument of power, prestige, survival, greatness and advancement of men and nations. It is also an agent of change, a key to knowledge and accelerated development. It is often viewed as a sequence of stages of intellectual, physical, and social development. Education had also been viewed as a continuous process where individual continue to learn, relearn and unlearn norms, values and attitudes to make them fit to the society they live. Various successive governments in Nigeria had placed education at its focal agenda in their service delivery to its people. Over the years, education has focused on access and parity that is, closing the enrolment gap between girls and boys, while insufficient attention has been paid to retention and achievement or the quality and relevance of education.Providing a quality, relevant education leads to improved enrolment and retention, but also helps to ensure that boys and girls are able to fully realize the benefits of education. The primary focus on girls’ access to education may overlook boys’ educational needs. This approach also fails to confront the norms and behaviours that perpetuate inequality. Gender issues in education had attracted national, international and intellectual recognition and interests. The perspectives, various interests and focuses had been on human rights, women inequality, women empowerment, girl-child educations, feminism, female educational opportunities performance etc. It is the opinion of this paper that these relative gender issues are more prevalent, obvious and consequential in Nigeria.
Protocol Coordination for Reliable Data Transfer and Error handling in MANET [PDF]
Tibabu BezaMobile Ad-hoc Networks have been increasing their popularity in recent years due to ease of deployment and low cost of its components. No infrastructure based network support is not required for MANETS because each node communicates with other nodes though the radio frequency. The routing protocols are challenged with establishing and maintaining multi-hop routes in the face of mobility, bandwidth and power constraints. The services provided by the current technologies for multimedia transaction is not sufficient in terms of quality of service and timely delivery of data. In this paper we tried to solve these type of problems by proposing reliable data transfer protocol, which is capable of delivering multicast and unicast data in mobile ad- hoc networks. The protocol has been designed to work on top of the IEEE 802.11 protocol without any modifications in the hardware structure.
