Valentino Aris, Haris Maupa, Yansor Djaya, Idayanti Nursyamsi

Abstract: The problem described in this research was to identify which factor influenced user behavioral intentional for the use of academic information system in universities in Makassar city, Indonesia. The objective to identify factors by proposing a Technology Acceptance Model (TAM), Theory Of Planned Behavior (TPB) and Costumer Perceived Value of an Academic Information System. The research method used in this research was quantitative method. Survey method using questionnaire instrument will be used to obtain primary data. A total sample of 398 student and lecturer from 6 universities were retrieved for the analysis. The method of data analysis used was Generalized Structural Component Analysis (GSCA). This study found that perceived usefulness, perceived ease of use, information quality and availability of information technology resource had a significant effect on behavioral intention and perceived value. Perceived ease of useand behavioral intention had a significant effect on actual use of academic information system while perceived usefulness, information quality, availability of information technology and perceived value was not significant with actual use of academic information system. Finally this study found that actual use of academic information system had a significant effect on user satisfaction.

Julius Ogwora Maraga, Philip Kipkoskei Kimaiyo, Prof. Lusweti Kituyi, Prof. Samuel Lutta

Abstract: Human activities such as agricultural and industrial operations have led to the accumulation of pollutants for example heavy metals in the environment since they are non biodegradable.. Consequently, there is need to remove these heavy metals from environmental matrices. The different conventional ways of removing heavy metals from the environment are expensive and mostly ineffective. Among these methods, biosorption has been proved to be efficient and cheap in heavy metal removal. Most common marine weeds have been found to be potent biosorbents. This study aimed at examining the capability of green algae in the biosorption of heavy metals from waste waters. The green algae were sampled from the University of Eldoret fish ponds, washed, dried and ground using pestle and mortar. Two selected heavy metal test solutions of Zn2+ and Cu2+ were used in the study. A 5 gram mass of the algae sample powder was transferred into 250 ml beaker containing a 100 mL solution of specific heavy metal at pH values 4, 7 and 9, and stirred for ten minutes. Ten ml samples were then taken from the reacting vessel at time intervals of 10, 20, 30, 40, 50 and 60 minutes and metal levels measured by the atomic absorption spectrophotometer. The results showed that for each of the two selected metals, the levels significantly increased in the biosorbent faster in the first 10 minutes, while the equilibrium reached after 50 minutes. For Cu2+ the maximum biosorption was found to occur at pH 9 and for Zn2+ at pH 7 while the least biosorption occurred at pH 4 for Cu2+ and for Zn2+ at pH 4. The isotherm data fitted Langmuir better than Freundlich from the values of R2. The R2 values for pH 4, 7 and 9 ranges, were found to be tending to one, indicating a strong positive relationship between the equilibrium heavy metal ions concentration (Ce) and the metal uptake (Qe). Freundlich, the correlation coefficients, R2, were found to be less than 0.900, indicating a weak positive relationship between the

Long Run Association and Causality between Macroeconomic Indicators and Banking Sector in Pakistan
Muhammad Ahmad Shahid, Lyba Shaheen

Abstract: The study investigated the long run relationship between selected macroeconomic indicators and banking sector index in Pakistan. The selected macroeconomic indicators are Exports, Industrial Production, CPI, KIBOR as short term interest rate, Money Supply (M0), Nominal Exchange Rate between Pakistan and United States of America (USA), Oil Prices and Interest rate on Pakistan Government bond 10 year, as long term interest rate. Monthly time series was used from January, 2009 to August, 2015. Study applied Augmented Dickey Fuller test to determine the stationarity levels for the selected macroeconomic indicators and banking sector index, Phillips-Perron test to validate the results of Augmented Dickey Fuller test, bound testing technique in ARDL model to investigate long run relationship between selected macroeconomic variables and banking sector index. Results suggested presence of long run relationship between macroeconomic variables exchange rate, inflation, oil price and banking sector index in Pakistan. Results of Granger causality test suggested unidirectional causality running from macroeconomic variables KIBOR and oil prices to banking sector index in Pakistan. Further, unidirectional causality was found running from banking sector index to government bond in Pakistan.

Physical and Chemical Properties of Water Hyacinth Based Composite Briquettes
Okia D.O., Ndiema C.K., Ahmed M.S.

Abstract: Biomass is one of the most promising energy sources to mitigate greenhouse gas emission during production and utilization. However, majority of biomass are not suitable to be utilized as fuel without an appropriate process since they are bulky, uneven and have low energy density. The study was conducted to evaluate the physical and chemical properties of water hyacinth composite briquette as an alternative source of energy. Water hyacinth was chopped using a shredder and left for two weeks in a heap to partially decompose. The material was thoroughly mixed manually with dried and crushed charcoal dust and cow dung in the ratios of water hyacinth: charcoal dust: cow dung of 100:0:0 (control), 80:10:10, 70:20:10, 70:10:20, 60:30:10, 60:20:20 and 60:10:30 (by weight). The resulting material was then mixed into soupy slurry in water.

Analyze the Impact of Knowledge Management on Organizational Performances
Charitha Harshani Perera , Rishan Duminda Ranawaka

Abstract: Knowledge management is a process that transforms individual knowledge into organizational knowledge. Many organizations have recognized that knowledge is the most important resource in today’s economy. Propelled by the resource- and knowledge-based views of the firm, organizations are actively embracing knowledge management with the expectation of acquiring and maintaining high levels of organizational performance. However, because knowledge management as a formal practice is still in its infancy and not yet well understood, many organizations are unable to attain expected performance.

Evaluation of Water Drilling Problems in a Transition Aquifer, a Case Study of Ogwashi Asaba Formation And Benin Formational Boundaries Within Orlu Area, Imo Sedimentary Basin Se Nigeria
Onunkwo A.A , Ikoro D.O , Israel H.O

Abstract: Aquifer identification problems in a transition environment have been studied with the aim of evaluating the major causes of water borehole drilling failures of transition environment. Vertical electrical sounding principles were employed in probing the vertical lithology of the areas lying within the transition Environment of Ogwashi Asaba and Benin Formation. The major equipment used in this operation is Scintex R Sp- 6 and signal average system SAS 300 Terrameter. The result shows that the lithological arrangement is chaotic and cannot be correlated. The borehole drill log and electrical resistivity survey of the underlying lithology doesn’t correspond because of the inter fingers of sediments which could not be detected by VES survey. This leads to error in total drill depth estimation. Most of the aquifers at the deep levels have no shale base making the total drill depth estimation a guess. A water bore hole in a single location may have aquifer at different levels of the well, therefore, multiple screens are ideal. Hand dug well is possible in some areas. No bore hole in the area should terminate before 90m (270ft). It was discovered that trilinear VES survey should be employed in the area. Where water bore hole drilling is difficult, hand dug well should be installed if possible. The VES report of one area should not be used for another, because the well cutting of any borehole does not match its vertical electrical resistivity results.
