GEOELECTRICAL INVESTIGATION OF THE SUBSURFACE USING 2D ARRAY CONFIGURATION IN UNIBEN ENVIRONS, EDO STATE, NIGERIA
Solomon E. O., Ogah V. A. Abstract: The two dimensional (2D) electrical resistivity survey was employed to investigate the subsurface layers within the engineering field in the University of Benin, Ugbowo Campus, Benin City. In this work, Wenner-Schlumberger array was used as protocol chosen for this investigated study. Field work was carried out along six (6) spreads in total in this location with length of about 230m and the depth of investigation is around 43.0m. After processing the result of the field work, data files were imported from a Pasi-Earth resistivity meter which had an inbuilt booster for computer interpretation using RES2DINV software to get 2D imaging of electrical resistivity sections. These sections reflects the subsurface complexity due to sediment heterogeneity.

Spatial Distribution of Survey Controls and Effect on Accuracy of Geometric Geoid Models (Multi-quadratic and Bicubic) in FCT, Abuja
Oluyori, P. D. and Eteje, S. O. Abstract: Spatially distributed studies may follow two broad approaches: points that are randomly located and points that are clustered or clumped together. They are discussed within a discipline described as geo-statistics. Geo-statistics is applied in order to interpolate geoid undulation (N) and hence generate through a geoid model orthometric heights from scattered/random or closely/clustered located controls. Control points are coordinated points within a primary/secondary geodetic survey network. Kriging method was adopted to produce topographical maps of the both scattered and closely scenarios. Accuracy computed revealed that standard deviation (σ) of multiquadratic and bicubic models in the study area are respectively 11cm and 14cm in lopsided control study area while over clustered distributed located controls are respectively 12cm and 15cm. Standard deviation with the lowest values among the determined geometric geoid models is at all times preferable scattered/random than closely/clumped scenario. This implies that the multiquadratic models can be applied across the entire study area with high accuracy/reliability irrespective of spatial distribution of the points. Hence, the accuracy of the models are better when the total number of points distributed within the entire study area was used than when a limited number of points within a particular part of the study area was used.
PERFORMANCE OF SISAL FIBER IN MANUALLY CRUSHED PALM KERNEL SHELL CONCRETE
Ishaya, A. A., Anowai, S. I., Yahaya, A. M., Williams, F. N. & Emeka, O. B. Abstract: One of the major challenges of our present society is the protection of the environment. Some of the important elements in this respect are the reduction of the consumption of energy, natural raw materials and the utilisation of waste materials. The used of waste is showing prospective application in construction as alternative to conventional materials. It conserves natural resources and reduces the space required for the landfill disposal. Palm kernel shell is a byproduct of the production of palm oil. Previous works indicate that palm kernel shell performs satisfactorily as an aggregate for lightweight concrete. This research therefore was carried out in an attempt to evaluate the performance of sisal fiber in palm kernel shell concrete. The palm kernel shell used for this research was determined to have a specific gravity of 1.36, bulk density of 574 kg/m3 and was therefore classified as lightweight aggregate. Values of water absorption and porosity of the shell were found to be 11.43% and 14.70% respectively. A mix proportion of 1:2:4 and water - cement ratio of 0.63 was adopted for all the concrete mixes. A total 36 concrete cubes of size 150mm x 150mm x 150mm were cast with 1%, 2% and 3% sisal fiber and were crushed to obtain the compressive strength at 7, 14 and 28 days of curing, 12 concrete beams were also produced and tested for flexural strength. An increase in compressive strength by 51.2% was observed at 3% . It was concluded that 3% sisal fiber can be adopted for lightweight concrete work.
Internal Audit and Profitability of Banking Institutions in Kenya: A Case Study of Commercial Banks in Kericho County, Kenya
Dr. Kimetto Richard Abstract: Banking sector faces myriad challenges in delivery of services to its clients. Among these include: ineffectiveness in internal audit and profitability in their mandates in providing banking services. Thus, the aim of this research was to find out the factors that impede effective internal audit and profitability of banking sector in Kenya based on a case study of Commercial Banks in Kericho Town. The study focused on the effectiveness of internal audit in Commercial Banks, to determine factors affecting profitability of Commercial Banks, and to establish the relationship between quality of internal audit and profitability. The data were collected using questionnaire and interview schedule. The study had a sample size of 30 employees sampled from various commercial in Kericho town using stratified random sampling method. The research findings indicated that: internal auditors contribute to profitability of firms mainly through detection of fraud and advising management on internal control system; also it indicated that the major constraints to internal audit effectiveness were lack of independence and lack of enough qualified audit staff. Profitability of Commercial Banks was mainly affected by high tax liability on profits, low productivity per employee and increasing cost of production. Furthermore it established that effective internal audit influence profitability of firms. The study recommends that if the Commercial Banks were provide effective internal audit and real its profitability they should provide a conducive working environment to the internal auditors to enable them executive duties well.
Assessment of Physical Parameters of Water of the Dhaleshwari River in Bangladesh before setting up Tanneries
Sarmin Akter, Md. Kamrujjaman, Md. Rashed-Ul-Islam Abstract: The rivers of Bangladesh mark both the physiography of the nation and the life of the people (Monirul Qader Mirza et al., 2003; Smith et al., 1998). These rivers generally flow south and they serve as the main source of water for cultivation and as the principal arteries of commercial transportation. Rivers also provide fish, an important source of protein. Flooding of the rivers during the monsoon season causes enormous hardship and hinders development, but fresh deposits of rich silt replenish the fertile but overworked soil (Bhuiyan and Dutta, 2012; et al., 2015). The rivers also drain excess monsoon rainfall into the Bay of Bengal. Thus, the great river system is at the same time the country’s principal resource and its greatest hazard.

Dr. Md. Shahedul Islam, Dr. Mohammad Masudur Rahman, Dr. Md Harun Ar Rashid, Dr. Md Forhad Abedhan, Dr. Md Shamsuzzaman Prodhan, Dr. Md. Abul Bashar, Prof. Dr. Md. Nizam Uddin Abstract: Parents attitudes toward their mentally retarded children are of paramount importance, because majority of such children are looked after at their home and parental attitude determines the efficiency and adequacy of the training measures to be adopted by the parents. Attitudes are determined by social influences, cognitive influences, behavioral influences etc. These influences jointly mold our earliest attitudes, and they can change our attitudes through our lives. Attitude strongly affect how a person perceive and respond to other people including their mentally retarded children. Unrealistic and self-defeating attitudes lead on to distort family interactions which greatly hampers. A descriptive cross-sectional and analytical study was done in Department of Psychiatry, Cumilla Medical College, Cumilla. All cases were selected from patients attending at Cumilla Medical College Hospital and Private Mental Health Facilities in Cumilla City from April 2014 to September 2017. The main objective of the present study was to investigate the attitudes of parents towards their mentally retarded children. Total 80 participants who fulfilled the enrolment criteria were included in the study. Wechsler Intelligence Scale for IQ assessment children (WISC-III) and Independent Adaptive Behavior Assessments Scale (IBAS) were used for diagnosing regarding mentally retarded children...
Analysis and fabrication of telecommunication outdoor sector antenna remote control unit
O.V Jayasinghe Abstract: The operational cost for outdoor sector antenna establishing and position optimization is being reporting as a higher value since last five to six years. The larger the customer base, the higher cost for GSM network expansion. Many practical and functional drawbacks have been identified in the traditional sector antenna positioning system such as sequence mistakes in manual adjustments, high initial cost for installation, high maintenance cost and low reliability for long term operations and projects. This research emphasis the optimization of the outdoor sector antenna with the proper use of remote device controlling systems with microchip programming such as Arduino interface. A requirement occurred to find out a proper wireless system with microchip programming in order to do the adjustments in electro/mechanical interface. This research has done the automated wireless control unit for the outdoor sector antenna and the prototype was successfully installed and tested in a selected region. Eliminating the issues and problematic situations of prevailing system and make the new system more useful in order to implement it as a new sector antenna direction changing practice was the key expectation of this research.
Phenomenological Research Methodology
Neville Greening Abstract: The phenomenological research methodology relates to several approaches that in turn, they are applied to single cases or to the deliberate samples that are carefully chosen. Like individual studies, it is easier to identify issues that show discrepancies, failures, favorable inferences, and attention to distinct situations while conducting management research (Groenewald, 2004 pg. 87). Clark Moustak as theoretical underpinnings of phenomenology guide the reader through the process of how to manage a phenomenological study step-by-step. And so, this provides more in-depth insights on the successful phenomenological studies from distinct contexts, including the field of healthcare, therapy, psychology, victimology, as well as investigations involving gender. While conducting a phenomenological research methodology, it often pertains the four necessary steps of Bracketing, Intuiting, Analyzing and Describing. This paper looks at Phenomenological Research Methodology Applied in a Nursing Context.
