In this article, we propose a Microstrip Antenna for Ultra Small Satellite (USS) telecommunication subsystem application in UWB (Ku frequency band and Ka band). The designed MA is based on circular patch antenna. We process by minimizing and adjusting the MA dimension to lift the latch of bandwidth while maintaining quality performance of other properties. We have developed a studied geometric shape and used tricks to design them. Obtained antenna feds by microstrip line and the ground plane. Antenna feed elements are placed on the same plate to reduce the spatial dimension. Successful results are presented to validate function of proposed design and its precision operating at high frequencies.

The concentration Heavy metals (Pb, Cr, Cd), macronutrients (Na, K, Ca) and physicochemical properties (Temp., pH, EC, TDS) of soil, vegetable and water were investigated using standard procedures. Soil sample was taken using auger with 0 - 20 cm depth, using zigzag method. To determine the statistical differences between more than two groups of data ANOVA were used and t-test were also used to compare between two groups of data. And each vegetables sample was collected from the same place where a soil sample was taken. Uncultivated area was taken as control. Except, potassium, all physicochemical parameters for both ground (GW) and surface water (SW) were within recommended range of the standards (WHO and FAO) for agricultural use. The pH for GW as well as SW was slightly alkaline. Except Pb, Heavy metals concentrations for soil and vegetables samples were below the safe limits for human consumption. This high Pb levels in meki may probably attributed to more vehicular exhaust fumes. But, when statistically evaluated, using ANOVA, heavy metals concentration in soil samples were all significantly different (P<0.05) from Controlled (uncultivated) area. This shows that anthropogenic activities leading cause of metal emission. The concentration of macronutrients for soils and vegetables analyzed in all parts are within the range set up by the standards. The main purpose of this work is to know the sources of heavy metals emission and to control it using different methods.

The study assessed the activities made available to farmers for participation through Fadama III Project in Bayelsa State. Objective of the study was activities made available to farmers through National Fadama III Agricultural project delivery agency. Purposive sampling technique was used to select One-Hundred and fifty (150) farmers that participated, and 150 staff from the delivery agency. Data were collected with a structured questionnaire. The data collected was analyzed using frequency count, percentage, mean (X ̅), standard deviation (STD), while z-test was used to test the null hypotheses at 0.05% level of significance. Farmers in the state truly believe in the existence of various activities in Fadama III project in the state as being made available to them through the delivery agency. The result of the z-test showed that the mean response of the farmers in Fadama III projects was 2.986 while the mean response of the delivery agency was 3.793, there was significant difference (z = -20.245) in the mean score response of the delivery agency and participants of National Fadama III Agricultural Project on the various activities that were made available to the farmers at P ≤ 0.05. The study therefore recommended that National Fadama III Project activities should be reorganized to be of great benefit to the farmers, proper training in all the activities should be made available for effective participation, empower the participants to improve their income level, and to move them away from poverty by improving their standard of living by reorganizing the Fadama III Project.

Lubricant markets are becoming even more competitive and therefore companies are relentlessly striving to reduce the inventory running costs to lessen the company expenses at a reasonable level in order to remain competitive in this highly volatile environment. It helps the companies becoming profitable and thus business grow. In this study our main goal was to focus on imported commodities from other branches of the company. The goods imported, due to the Company Policy, are not manufactured in the country. We try to improve existing model and to adopt above mentioned goods for calculating the safety stock levels that the company, especially during high seasons, experiencing stock outs resulting inevitable business losses. We presented a cost model approximation. It is shown that the proposed model not only reduce substantial cost of inventory, but also help to meet the customer expectations without employing highly expensive sophisticated software tools and therefore, it substantially aims to increase customer service level too.

This paper aims to evaluate the performance of target detection in the presence of sea clutter. Radar detection of a background of unwanted clutter due to echoes from sea clutter or land is a problem of interest in the radar field. Radar detector has been developed by assuming the radar clutter is Gaussian distributed. However, as technology emerges, the radar distribution is seen to deviates from the Gaussian assumption. Thus, detectors designs based on Gaussian assumption are no longer optimum for detection in non-Gaussian nature. The theory of target detection in Gaussian distributed clutter has been well established and the closed form of the detection performances can be easily obtained. However, that is not the case in non-Gaussian clutter distributions. The operation of radar detection is determined by radar detection theory with different types of Swerling target models; such as Swerling I, II, III, IV and V. By using MATLAB, these signal detection techniques are developed.

The study was to assess household perception of water quality and its associated health consequences. Nine water samples were collected from three water sources and transported to the Water Research Institute, laboratory for analysis and 120 questionnaires were randomly administered. The physico-chemical values were within the Ghana Standard Board and World Health Organization maximum limits for potability except turbidity and nitrate concentrations. Nitrate concentrations ranged from 1.19 to 46.97 mg/l with a general mean value of 14.11 mg/l. Generally, there was a significant difference (P < 0.05) in some physico-chemical parameters values and E. coli count for the three water sources. The microbial count exceeded GSB and WHO limits for potability except Escherichia coli making the water unwholesome for drinking purpose. The community’s perception of water quality did not reflect much in the laboratory analysis. It is recommended that, proper treatment should be done at the household level to prevent health implications.

Global Positioning System (GPS) is used in numerous applications in today’s world. A real time vehicle tracking system using the GPS technology is proposed in this paper. The project Android App based Vehicle Tracking Using GSM AND GPRS mainly focuses in tracking the location of the vehicle on which the device has been installed. It will then send the data in the form of latitude and longitude coordinates through SMS on the user’s mobile where the coordinates will be plotted in the Android app automatically. Initially, the GPS installed in the device takes input from the satellite and stores it in the microcontroller’s buffer. In order to track the vehicle, the mobile user has to call on the SIM number that is registered in the GSM module of the device. Once the call is received, the device authenticates the calling number. If authenticated, the location of the vehicle is sent to the registered mobile number in the form of SMS. After sending the message, the GSM is deactivated and the GPS is activated again. The coordinates of the location received in the SMS can be viewed on the android app. The hardware part described in the paper comprises of GPRS, GSM module, LCD to view the coordinates, ATMega Microcontroller MAX 232, Arduino, RS232 and relay.

Human capital is a paramount important part of todays’ business world. For any company to achieve its corporate strategies, it is important to have motivated, committed workforce within the company. Therefore keep employees satisfy is a necessity for any organization. Otherwise they may leave the company as there are lots of job opportunities remain in this modern business world. This study focus on how reward system of an organization impact on employee turnover intention. This study empirically evaluated five independent variables (remuneration, cash incentives, work life balance, supervisor support and employee recognition) and their relationship to the turnover intention of non-executives in the logistics industry of Sri Lanka. The sample consists of 97 non-executive staff in the logistics industry of Sri Lanka. The data collection was done by using a self-administrated structured questionnaire. The results indicated that remuneration, cash incentives, work life balance, supervisor support and employee recognition variables were negatively and significantly correlated with turnover intention. And those relationships were strong. Results of regressing the reward system on turnover intention showed that reward system is a powerful predictor of labour turnover in logistics industry of Sri Lanka. The research findings give evidence that better financial and non-financial rewards have strong impact on employee turnover intention. Therefore to reduce employee’s high intention to leave the company, the management needs to develop well balanced reward system in both financial and non-financial aspects.

This study investigates the role of buffalo colostrum and milk whey derived peptides in protection against oxidative damage induced by 2, 4-Dinitrophenol (2, 4-DNP) in human blood serum samples in vitro. A biomarker enzymes for oxidative stress like Alkaline phosphatase (ALP) and acid phosphatase (ACP), oxidative damage markers indicating extent of host antioxidant reserve indicators like reduced glutathione (GSH) were measured by spectrophotometric techniques in four different groups namely (1) Human blood plasma only (control) , (2) Human blood plasma + 2,4-DNP, (3) Human blood plasma + colostrum whey derived peptides + 2,4-DNP ,(4) Human blood plasma + colostrum whey derived peptides , (5) Human blood plasma + milk whey derived peptides + 2,4-DNP and (6) Human blood plasma + milk whey derived peptides. Following exposure to 2, 4-DNP, levels of antioxidants like GSH was significantly decreased in comparison to control, e.g., GSH [0.568 ± 0.015 vs0.871 ± 0.022µmol/0.1 mg proteins. In addition, the concentration of biomarker enzymes for 2,4-DNP induced membrane damage and oxidative stress like ALP and ACP were increased in serum by oxidant compared to control, e.g., ALP [5.497 ± 0.185 vs. 2.782 ± 0.000µmol/mg protein], ACP [1.689 ± 0.047 vs. 0.629 ± 0.047µmol/mg protein]. Pretreatment with buffalo whey derived peptides significantly protects 2,4-DNP induced RBC membrane lyses and release of ALP and ACP into serum environment. e.g., ALP [3.444 ± 0.094 vs. 5.497 ± 0.185 µmol/mg protein], ACP [0.629 ± 0.047 vs. 1.689 ± 0.047µmol/mg protein]. Pretreatment with whey derived peptides give protection to oxidative damage and shifts the trend towards amelioration and replenishment of the antioxidant status.

Solar energy is rapidly gaining ground as an important mean of expanding renewable energy use. Solar tracking is employed in order to maximize collected solar radiation by a photovoltaic panel. In this paper we present a prototype for Automatic solar tracker that is designed using Arduino UNO with Wind sensor to Cease Wind effect on panels if wind speed exceeds certain threshold. The Proposed solar tracker tracks the location of the sun anywhere in any time by calculating the position of the sun. For producing the maximum amount of solar energy, a solar panel must always be perpendicular to the source of light. Because the sun motion plane varies daily and during the day it moves from east to west; one needs two axis tracking to follow the sun's position. Maximum possible power is collected when two axis tracking is done. However, two axis tracking is relatively costly and complex. A compromise between maximum power collection and system simplicity is obtained by single axis tracking where the plane (North south axis) is fixed while the east west motion is accomplished. This work deals with the design of both single and two axis tracking systems. Automatic trackers is also compared to Fixed one in terms of Energy generated, Efficiency, Cost and System reliability.

In the construction of public facilities and infrastructure, attention should always be given to matters that are directly or indirectly related to the construction of such facilities and infrastructure. As in the construction of drainage, there are several things that affect it, one of which is most often used as a reference in the calculation of drainage channel dimension is maximum rainfall or maximum daily rainfall intensity. Tanjung Selamat is chosen for study because this road is a liaison route for the surrounding community activities and Tanjung Selamat area and Medan city or Pancur Batu District. Therefore, it is necessary a review of the existing drainage channel of rapid development that occurred in Jalan Flamboyan Raya of Tanjung Selamat village both residential areas and places of business. This situation reduces the area of water catchment so that water is often abundant and make the existing drainage channel cannot accommodate it. This research is conducted in several stages, and with Pearson's Log Distribution Method of Type III which aims to determine the magnitude of the peak flood discharge in a particular repetitive period. Based on the results of research and calculations that have been done know that the amount of existing drainage discharge ( )is smaller than peak flood discharge ( )in the area around Flamboyan Road Raya of Tanjung Selamat village. Other causes of the flooding that occurred in the location where the research that the authors do is human behavior that is not friendly to the environment such as littering haphazardly or into the drainage channel, less attention to the maintenance of drainage channels around their dwelling, soil-walled conditions so very vulnerable to changes that affect the ability of the channel to drain the water. Equally important is the development around Jalan Flamboyan Raya of Tanjung Selamat village especially the establishment of various buildings either for residences or for business places resulting in reduced water catchment area. To overcome the problem of puddles / floods with the concept of minimizing or eliminating it in the area around Jalan Flamboyan Raya of Tanjung Selamat village which has an area of water puddle  6.839742165 Ha is rearranged the existing drainage network.

Soybean (Glycine max .L) is an important food crop in Rwanda and has recently been identified as one of the priority crops for the Crop Intensification Program (CIP) for the country. However, its productivity is low, standing at about 0.8 t/ha against the potential of 3-5 t/ha, depending on the varieties used. The use of organic and inorganic fertilizers to increase soybean productivity is constrained by their high cost to most small scale farmers. Use of farm yard manure is also limited by the unavailability of livestock to most soybean growers. In this regard, the most viable alternative to fertilization would be deployment of Nitrogen-fixing microorganisms to soybean farming systems. These, however, need to first be tested on the available soybean varieties. A field experiment was carried out in Nyarubaka sector of Kamonyi District to evaluate the response of two soybean varieties (Peka6 and SB24) to Rhizobium inoculation without limitation of phosphorus. The experiment was laid down in completely randomized block design with three replicates. The results obtained showed significant differences (P < 0.05) in grain yields and nodules mean score between inoculated and no inoculated treatments. The variety Peka6 responded to the Rhizobium inoculants more than SB24. Although further studies need to be conducted to obtain conclusive information on these Nitrogen fixers, the study indicates that Peka6, in combination with the right Rhizobia inoculants, could be recommended to replace conventional fertilization for our poor farming households

The purpose of this study was to optimize the formulation of ointment base by using statistical mixture design. Screening of hard thickeners (Palm Stearin, Beef Tallow and Beeswax) was done to choose the best hard thickener or combination of hard thickeners whose nature and proportions would give the best semi-solid and consistent ointment with desired rheological properties (Spreadability, viscosity, hardness). Contour plots of each response were depicted, based on the equation given by the statistical-fitted models. The optimum area for the ointment base properties, were located and the combination Beeswax:Palm stearin:Beef Tallow was chosen. Other optimization was done to check the contribution of different factors (Hard Thickener, Soft Thickener and Lubricant) on the rheological properties and their correlation. A strong inverse correlation was found to exist between the spreadability and the viscosity of the ointment base (91%). A multi-response optimization was done to obtain a combined optimum proportion of ingredients that gave us 5% HT, 84%ST and 11% L. It can be concluded that the ointment base obtained with optimal rheological and drug release properties can be used for cosmetic and pharmacological applications. The plant extracts can be incorporated in this matrix for herbal ointments.

Cloud computing is a novel technology in the field of distributed computing. Usage of Cloud computing is increasing rapidly day by day. In order to serve the customers and businesses satisfactorily, fault occurring in datacenters and servers must be detected and predicted efficiently in order to launch mechanisms to tolerate the failures occurred. Failure in one of the hosted datacenters may propagate to other datacenters and make the situation worse. In order to prevent such situations, one can predict a failure proliferating throughout the cloud computing system and launch mechanisms to deal with it proactively. One of the ways to predict failures is to train a machine to predict failure on the basis of messages or logs passed between various components of the cloud. In the training session, the machine can identify certain message patterns relating to failure of data centers. Later on, the machine can be used to check whether a certain group of message logs follow such patterns or not. Moreover, each cloud server can be defined by a state which indicates whether the cloud is running properly or is facing some failure. Parameters such as CPU usage, memory usage etc. can be maintained for each of the servers. Using this parameters, we can add a layer of detection where in we develop a decision tree based on these parameters which can classify whether the passed in parameters to the decision tree indicate failure state or proper state.

Lifestyle is a habit of one's life that can affect his health status in the future. Hypertension is a relatively disguised problem but it contains great potential for big problems as well. Hypertension can cause disability or even death. the authors are interested to examine the influence of lifestyle on the incidence of hypertension in adult age (30-40 years) in the Polyclinic of Internal Medicine RSUD dr. Saiful Anwar Malang. This study will produce a picture of the lifestyle of patients who control in the Polyclinic of Internal Medicine dr. Saiful Anwar Malang, aged between 30-40 years, will further investigated the lifestyle and if there any influence on the incidence of hypertension in adulthood (30-40 years). The research design used is descriptive method. Descriptive method is a method of research conducted with the main purpose to create a picture or description of a situation objectively. Population in this research is patient who control in Polyclinic of Internal Medicine RSUD dr. Saiful Anwar Malang with the age range between 30-40 years with the number of 295 people for the average of 2 weeks. Based on data obtained in the study (such as attachments 8 and 9) on the results of data processing lifestyle of patients , it can be stated that there is no lifestyle influence on the incidence of hypertension at adult age (30-40 years) in Internal Disease Polyclinic in RSUD dr Saiful Anwar Malang. The number of questions per subvariabel is not the same, so the result of lifestyle picture obtained is not proportional. When working on the problem is when the patient is waiting for a doctor to come or wait to be called for review, so the possibility of the patient is not concentrated in answering questions.

This paper has been presented to outline some issues with the institutional theory and it is based on the theoretical understanding. In order to conceptualize the rules, their pragmatic application will be discussed. There are many efforts have been made to develop this theoretical perspective for developing empirical understanding of the theory. During recent years, this theory went through major advancements and gained popularity; however, we believe that it has several significant theoretical/methodological issues, which limit its applicability and effectiveness. The most important issues include static institutional explanations, and difficulty while calculating some institutional variables. In this study, we have addressed a major issue with this theory, which is its static nature, using the “institutionalization” concept, explaining institutional structures, and developing better institutional explanations. This study negates/refutes the claims of many researchers, who stated that the institutional theory is rich in concepts and has advanced to, "warrant more formal models and codification." The present study is an effort to resolve the conflict between researchers belonging to different schools of thought on the theory. In this paper, we tried to identify the range and depth of the conflicting concepts and areas of agreement. This paper demands of researchers and specialists to clarify their stance providing details and contributing towards this theory's further development, which will certainly benefit researchers and professionals in this field.

In this paper, the results of the energy audit of buildings in Arba Minch Institute of Technology (AMIT) are presented. The objective of the study was to identify the energy lossy applications, activities and traditions and to suggest the least costly energy conservation mechanisms. All functional lighting systems, office equipment, desktop computers and water fixtures (showerheads, dishwashers, toilet flushers and hand washers) are taken into consideration for the study. Increased energy consumption due to daytime operation of lighting systems, inactive mode operation office equipment and desktop computers and poor water management practices were the focus of the study. Based on the audit results, poor water management practice in the campus contributes the most to the total energy loss followed by the inactive mode energy consumption of desktop computers and daytime operation of outdoor lighting systems. Therefore, a significant amount of energy can be saved by practicing regular maintenance of water fixtures and pipes in the campus. Moreover, awareness creation campaign can help a lot in reducing the energy loss, which could be resulted from inactive mode energy consumption of computers and daytime operation of lamps. Installation of electronic day light control and motion detection systems can be potentially used to reduce the energy consumption of lighting systems operating in the daytime and in class rooms and halls both in the day and night time respectively.

The climate resilient cluster village with handlooms was established by an NGO named “ActionAid Bangladesh” with the objective of ensuring secure living and productive service for sustained livelihood in the Jamuna river basin of Bangladesh. The experience was that the poor people had their handloom factories and dwellings devastated by flood almost every year with consequential threat to livelihood and dignity of the women. It was therefore felt essential to facilitate them in building multi-hazard resilient handloom factories so as to make them self-protective from windy storm, foggy weather, monsoon flooding theft etc. The program started with a threadbare discussion with the vulnerable communities in a participatory manner where the program staffs has sat with the community groups, especially the poor, to generate the basic analysis of vulnerabilities, the community is facing and its link to climate change. The community itself did the analysis and analyzed the vulnerability faced by them. The result is building of climate resilient handloom industry for 10 families whose industrial unit and dwellings were devastated almost annually by flood. A variant of a social and economic analysis is carried out to determine scaling up of these types of adaptations to similar ecological zones of the country and elsewhere.

The prevention of pathogenic bacteria by lactic acid bacteria (LAB) isolated directly from foods is an innovative approach. With the aim of determining the anti-bacterial activity of Lactic acid bacteria isolated from “ergo” and “qotchqotcha”, Ethiopian fermented food, 12 samples of each were taken from the 4 different kebeles of Assosa town. Isolation of LAB from the selected samples were carried out using MRS media. The different set of isolates were characterized using primary biochemical tests. Isolates which were gram positive, catalase negative and KOH negative were considered to be presumptive LAB and further characterized by using different biochemical tests for further identification. 16 isolates from ergo samples were isolated. Based on Bergey’s manual of determinative bacteriology, the 16 isolates belonged to four (4) LAB species, namely Lactobacillus acidophilus (18.75%), Lactobacillus casei (31.25%), Streptococcus thermophiles (25%) and Lactobacillus bulgaricus (25%). Likewise, 5 isolates were isolated from Qotchqotcha and the five isolates were found to be Lactobacillus acidophilus (80%) and Pediococcus acidilactici (20%). Cell free solution from MRS broth culture of theses LAB was prepared and tested against Escherichia coli O157:H7 and Staphylococcus aureus using agar-well diffusion method. Of the 16 isolates isolated from ergo, 9 of them show antimicrobial activity against E. coli O157:H7 (with a largest inhibition zone measured about 7.33±1.20mm by EK0101) and 12 of them show antimicrobial activity against S. aureus (with a largest inhibition zone measured about 11.66 ±0.88mm by EK0201). On the basis of morphological and biochemical test done, EK0101 was found to be presumptive Lactobacillus acidophilus and EK0201 to be Streptococcus thermophiles. All of the isolates isolated from Qotchqotcha showed antimicrobial activity against the tested organisms though there was a significant difference in their activity (P<0.05). The isolate QK0201 showed an inhibition zone of about 6.67±0.88 mm against E. coli and 12.3±1.20 mm against S. aureus. QK0201 was also found to be presumptive Lactobacillus acidophilus. Generally, in this study, ergo and qotchqotcha were found to be a good source of LAB which have the potential to inhibit the growth of many pathogenic bacteria such as E. coli and S. aureus. So, there is a possibility to use them as an alternative therapeutic agent with no risk of antibiotic resistance and also against spoiling microorganisms.

This paper examines the dynamics of food supply per capita and undernourishment in Sub-Saharan Africa (SSA) for a panel of 42 countries. The dataset was constructed from the FAO and the World Bank global databases for four rounds in five-year intervals. Ordinal measures of national food supply status were generated from daily calorie supply per capita of SSA countries. Regional and inter-temporal dynamics of food supply status (very low, low, medium), transition rates, and the associated forces underpinning this dynamic process were analyzed and stylized by parametric and non-parametric measures. Economic and socio-demographic factors and regional heterogeneities determining the dynamics of food supply situation in SSA were identified by random-effects ordered probit model. The empirical findings indicate that the food supply level of SSA countries was enhanced by agricultural production and industrial value added, as a proxy for structural transformation. However, it was adversely affected by military expenditure, inflation level of consumer prices, proportion of rural population, age dependency ratio, and regional heterogeneities. The likelihood of SSA countries to face incidence of very low, low and medium calorie per capita supply was 23 percent, 61 percent and 16 percent, respectively. To improve the level of food supply per capita and thereby to reduce food poverty situation, SSA countries and other stakeholders need to focus on policies designed to enhance economic growth through agricultural production, creation of employment opportunities with structural transformation, enhancing health care services, improving their demographic structure through family planning, and controlling national and regional shocks and instabilities.

Flavour development in cheese is a complex process in which major catabolic pathways involved. Initially, the curds of different cheese varieties have almost the same flavours, however the curd produce flavour compounds which lead to discrimination among cheese verities in terms of flavour throughout ripening. The major biochemical pathways involved throughout ripening of cheese are the followings; liberation of FFA (free fatty acid), associated catabolic reactions, the degradation of the casein matrix to peptides and FAA (free amino acids), the reactions for catabolism of FAA and the metabolism of lactate and citrate. In this review, the general pathway for formation of volatile and non-volatile flavour compounds are stated and detailed knowledge as to products of amino acid catabolism, proteolysis, lipolysis, lactate and citrate metabolism well discussed.

It is the object of the presented paper to provide an electromechanical rotary valve actuating system for opening and closing valves of an internal combustion engine, capable of separately controlling both the inlet and exhaust valve operations of each individual cylinder in a multi-cylinder engine. This indicates that only one valve will be required for each cylinder of the engine. Previously published versions of this concept require a separate valve for intake and exhaust in each cylinder. The system provides an alternative to the camshaft assembly, in an attempt to overcome the limitations and inadequacies inevitably posed by a fully mechanical system. The prototype development is approached in a theoretical manner, beginning with the conceptualization and design of a rotating disk with a notches and corresponding closure surfaces to open and close the flow path. The actuated disk and notch design is then refined and followed by the design of an inlet and exhaust manifold to correspond to the valve design, and the theorizing and design of a sealing gasket. The rotating speed of the valve is determined by a general idling speed, and can be varied to provide variable valve timing with the motor. The final assembly eliminates a majority of the moving parts currently used in camshaft systems, like the cam, camshaft, rocker arm, push rod and springs, and results in a significantly lighter valve actuation system. By eliminating the translatory motion of valves, the problem of valves slamming on the valve seats at high velocities is eliminated, thus greatly reducing engine wear.

Ghanaian water bodies have been under threats recently, ranging from illegal mining, sand winning, reclamation of water bodies for the purposes of human settlement, pollution, etc. Civil and mechanical installations on the coastal waters have increase due to the discovery of oil recently and such situations are not spared by oil spills. Oil spills are an inevitable consequence of the need to produce, store, and transport oil. The commercialization of oil production has placed Ghana among High-Risk Zones which are characterised by high traffic density and the presence of navigational hazards. Despite Ghana’s awareness about oil spill accidents in both preparedness and response, it is likely it will be compromised when any accident occurs as it has more pressing demands on finite funds and resources. This situation might place Ghana among ill-prepared countries against oil spill combat. An important part of contingency plan is the prediction of locations that are susceptible to oil after spillage. This can be done by the use of satellite information, reviewing and comparing previous incidents, laboratory work or by fine tuning models which as of now the country is not having despite all the precautions to prevent oil spills. When spill models are used properly, they provide ecological, economic and social benefits. Hence, the need for such decision-making tool for Ghana to create an environment for the contingency plans to be tested, validated and upgraded. Such exercises not only maintain and increase the skills of the response personnel, but also lead to improvements and fine tuning of the plan as weaknesses and gaps are identified.

Fault, power loss and increasing demand for power by the various consumers pose a great challenge to the stakeholders in the energy sector. This study presents analysis of fault and power loss on 11kV network in Ado-Ekiti power distribution system. In order to achieve this aim, operational problem involving network unavailability due to fault occurrences and power loss due to outage are valuated and analyzed using descriptive statistical method. In the course of the study, outage events and durations, downtime of disconnected loads and nature of faults were observed and captured for analysis using statistical method. It is alarming, as this study reveals that substantial portion of the total power supplied to Ado-Ekiti in four years was lost as a result of the faults on the four (4) 11kV feeders in the State capital. Analysis of the result shows that frequent open circuit and earth faults are the causes of the losses and the implications on the economy in four years under consideration was estimated at one hundred and eight million, eight hundred and thirty five thousand, nine hundred and sixty eight naira (N108, 835, 968 .00). The percentage contribution of each feeder to the total fault of the network between 2008 and 2011 range from approximately 17% to 31% while the percentage contribution of each feeder to the load loss of the network range from approximately 17% to 33%. It was observed that reduced outage on the feeders and quick response to faults whenever it occurs are the ways of eliminating or reducing the losses.
