Abstract: Ten road - cut samples collected from five lithological sections of Lokoja sandstone formation in the Middle Niger basin were investigated using integrated granulometric, petrographic and geochemical analyses. Results of grain size analysis; standard deviation and skewness which ranges from 0.08 to -0.05 and 0.59 to -0.07 respectively suggest very well sorted to moderately well sorted sediments. Lokoja sandstone is strongly coarsely skewed and dominantly leptokurtic implying river laid sediments deposited by low energy current. The graphic mean falls between 0.1 and 1.35 suggesting mainly medium to coarse grained sediments. A mineralogical constituent includes quartz, feldspar, mica, rock fragments, clay matrix and cement fraction. The low quantities of quartz and feldspar classify the sandstone as Lithic Arenite. Heavy mineral petrographic results show that the opaque minerals constitute about 72.99% and non-opaque mineral suites of zircon, tourmaline, rutile, staurolite, sillimanite, garnet, apatite and epidote which is indicative of igneous and metamorphic sources, perhaps from the southwest and north central Basement Complex terrains. The calculated mineral maturity index (MMI) and zircon-tourmaline-rutile ratio (ZTR) indices suggest mineralogically immature to sub-mature sediments. The plot of SiO2 versus Al2O3 + K2O + Na2O reveals semi arid to arid conditions for the Lokoja sandstone with varied maturity. The geochemical datasets reveal mature lithic arenites including sub-greywacke and protoquartzites. The chemical index of alteration (CIA) and mineralogical index of alteration (MIA) values (79.37 and 58.74 respectively) implied that their source area underwent “intense” recycling but “moderate to high” degree of chemical weathering. The discriminant function plot shows that the plotted sandstones were predominantly derived from felsic igneous source. Besides, the lower ratios of Ni/Co, Cr/Ni, Cr/Th, Cr/Sc, Th/Sc, La/Co and Th/Co suggest felsic source rock. The K2O/Na2O versus SiO2 binary tectonic diagram shows source materials in the field of oceanic island arc. The Th-Co-Zr/10 and Th-Sc-Zr/10 ternary diagrams also plotted in the field of oceanic island arc.

Abstract: Four isolates of Bacillus licheniformis producing thermo-stable amylase enzymes were previously isolated from different Sudanese soils and designated as B. licheniformis SUDK1, SUDK2, SUDK4 and SUDO. The enzyme was partially purified using DEAD Sephadex A 25 gel filtration and then were identified using thin layer chromatography. Optimum pH and temperature for enzyme activity were determined. The effect of thermal stability was detected at two storage temperatures (-20°Cand 4 °C) for 24 weeks. The results showed that the activity of the partially purified enzymes increased up to 16 -18 folds. The amylase enzymes were found to hydrolyze starch forming various maltooligosaccharides, such as dextrins and maltose as major products so they were identified as α- amylases. Optimum temperatures for enzyme activity was obtained at 60 and 70 °C. All enzymes were stable between pH 6.0-9.0 with optimum pH 7.0 . The enzymes were stable and retained nearly all of their initial activities at -20 °C till the end of 24th week. At 4 °C they lost less than 60% of their initial activities at the 8th week. The Km values were 1.25 – 2.0 mg/ml.

Abstract: Anthropogenic activities had significantly distressed the availability and accessibility of reliable domestic water with sufficient quality. Yet available improved sources are scarce living city slums and urban peripherals dependents of groundwater. The role played by anthropogenic activities upon nutrients, heavy metals and organic content of groundwater was the focus in order to establish the existing water quality and its health implications. Experimental investigation revealed that overall amount of nitrate was higher, 3.361 ppm than ammonia, 0.20 ppm and nitrite, 0.0697 ppm. While 0.541 ppm being the highest recorded amount of phosphorus, 53.64 ppm was the highest amount of COD recorded. Fair amount of heavy metals including Zn, Cr, Cd and Cu observed to range between 0 to within acceptable limits, however the amount of lead from residential deep well, 0.0369 ppm was above WHO guideline. Waterborne cases like diarrhoea increased annually from 2007 to 2010 whereby cholera cases were irregularly fluctuating. Computation of Water Quality Index revealed that observed water quality rarely departed from natural levels.

ABSTRACT: The optimum nutrient and environmental growth conditions of three strains of Lentinula edodes (Le 75, Le P and Quagu) were investigated for their ability to grow under different temperatures, on some selected natural media, at different light durations as well as different acidities. Temperatures investigated ranged from 16oC to 30 oC. Optimal temperature for the development of all the three strains of L. edodes was at 25oC. The five selected natural media were; maize, rice, millet, sorghum meal agar and potatoes dextrose agar. The best mycelial growth on natural media was recorded on sorghum meal agar. The mycelia growth rates were also investigated under light durations. The best growth of L. edodes was in constant 24 hrs darkness for all the three strains and the differences between them were significant (P≤0.05). Mycelial filaments were relatively dense when it was incubated in alternating shifts of dark/light conditions; this showed that light is an important factor in the mycelial characteristics of this fungus. This baseline data obtained on these parameters is necessary for the cultivation of Lentinula edodes in Ghana as it is being introduced into the country for the first time.

Abstract: Power production and distribution in Ghana is ever more becoming erratic and expensive, both for the power producer and the consumer. It is in this regard that an investigation of hydrothermal power generation scheduling is undertaken for a major power producer in the country. The goal of the study was to determine an optimal power production schedule that meets daily load demands at minimum cost of production and also ascertain the marginal cost of producing electricity per day and therefore tariff rate. The problem was formulated as Mixed Integer Linear Programming (MILP) and the resulting model tested using real data obtained from a major power producer in Ghana. The test results show that daily load demands could be met at a minimum cost. Furthermore, the marginal cost of producing power obtained from the dual of the MILP model provided insight into the appropriate Tariff that is reasonable for the power producer to charge consumers.

Abstract: The study evaluates soil fertility status of rice fields in the eleven (11) municipalities of Catanduanes, Philippines. A stratified random sampling was used to cluster sampling sites into strata and come up a random proportional population size. Soil samples from each sampling site were gathered and analyzed for organic matter (OM) content, soil pH, available phosphorus and potassium following the BSWM (Bureau of Soils and Water Management) procedures with the aid of Soil Spectrophotometer and Flamephotometer (SPF-3).Soil texture and soil color of the samples were also determined using feel method and visual comparison, respectively. Results were implicated into individual fertilizer recommendation peculiar to sampling site within respective municipality. Moreover, a soil fertility map was delineated thru DIVA-GIS software by plotting local coordinates in Google Map. With reference to ideal pH for rice, six (6) towns exhibited favorable pH (5.5-7.0) range while five (5) towns were observed with strongly acidic (pH<5.0) condition. Suggested pH amendments include calcium carbonate (CaCO3) applications and or field submergence of rice fields having pH below 5.5. For Organic Matter (OM), (following the soil fertility rating of >3% - favorable; <3% - unfavorable to plant rice) six (6) towns showed favorable results for planting rice while five (5) towns registered low OM content. Ten (10) municipalities exhibited high available phosphorus>10ppm (Olsen P method) while six (6) municipalities categorically indicate high K content equivalent to≥82ppm. The overall mean results for soil pH level, OM, P and K content of majority of the rice fields in Catanduanes, Philippines werefavorable for lowland rice production, however, the ideal pH and NPK levels may be constantly checked following the recommendations given to maintain optimum possible harvests of rice.

Abstract: Fault ride-through (FRT) is necessary for large wind farm in most power systems. Fixed speed wind turbines (FSWTs) are a fading but important sector in the fast-growing wind turbine (WT) promote. State-of-art technique applied to assemble grid needs for FSWT wind farm is blade pitching and dynamic reactive power compensation (RPC). Blade pitching is controlled by the difficult mechanical loads forced on a wind turbine during quick power re-establishment. Dynamic RPC is forced by its high capital cost. These present technologies can therefore be limiting, particularly when linking to smaller power systems. A new choice equipment is projected that insert series resistance into the generation circuit. The series dynamic braking resistor (SDBR) dissipates active power and boost generator voltage, potentially displacing the need for pitch control and dynamic RPC. In this project we use a delegate wind farm model to study the useful effect of SDBR. The relations between wind turbines and grid results in rising short-circuit level and fault ride-through (FRT) capacity problem throughout fault situation. In this paper, the bridge type fault current limiter (FCL) with discharge resistor is used for solve these trouble. For this FCL, a control system is planned, which use the dc reactor current as control changeable, to change the terminal voltage of induction generator (IG) without measure any parameter of scheme. In this paper, the wind energy conversion system (WECS) is a fixed-speed system able to with a squirrel-cage IG. The drive train is representing by a two-mass model. The analytical and simulation studies of the bridge-type FCL and proposed control system for restraining the fault current and recovering FRT ability are offered and compare with the force of the request of the series dynamic braking resistor (SDBR).

Abstract: Increase in demand for crude oil, petrochemicals and natural gas have resulted in exploration for more oil wells in Niger Delta Region of Nigeria with consequent pollution of the environment. The terrestrial ecosystem and shorelines in the oil producing communities are under continuous cultivation. Environmental pollution by the industrial and domestic activities may therefore have far reaching implication on the agricultural productivity of the area and multiplier effect on the socio-economic wellbeing of people. It is on this background that this investigation “Dry and wet season’s dynamics in concentrations of Ni, V, Cd, Pb, Mn, Fe, Co and Zn in soil samples within farmlands in Ibeno Coastal Area, were investigated using atomic absorption spectrophotometer Unicam 939 model was carried out. The rank profile of mean concentrations of the heavy metals in mg kg-1 in the soil samples during dry and wet seasons was : Fe (12.09±4.98) > Mn (9.66 ± 2.18) > Zn (0.50±0.26) > Co (0.27±0.27) > Pb (0.26±0.39) > Ni (0.05±0.03) > V (0.04±0.01) > Cd (0.04±0.02) and Fe (12.09±4.98) > Mn (9.66 ± 2.18) > Zn (0.50±0.26) > Co (0.27±0.27) > Pb (0.26±0.39) > Ni (0.05±0.03) > V (0.04±0.01) > Cd (0.04±0.02) respectively. The concentrations of iron ranked the highest in both seasons. The amounts of the heavy metals in soil samples were higher in dry season than wet season. The pollution consequences of investigated heavy metals as well as their attendant health hazards on humans, livestock and economic crops have been discussed based on the results obtained, international standards, controls and available related literatures. All the metals investigated showed a significant increase in concentrations when compared to control samples but within maximum permissible range as recommended by World Health Organization (WHO) and Department of Petroleum resources (DPR) limits. This implies that the level of pollution of the soil of the studied area as regard the investigated heavy metals is insignificant. Hence, domestic animals, plants and human being are not at risk of contamination.

Abstract: Introducing texts to word processing tools may result in spelling errors. Hence, text processing application software’s has spell checkers. Integrating spell checker into word processors reduces the amount of time and energy spent to find and correct the misspelled word. However, these tools are not available for Afaan Oromo, Cushitic language family spoken in Ethiopia. In this paper, we describe the design and implementation of a non-word Afaan Oromo spell checker. The system is designed based on a dictionary look-up with morphological analysis (i.e. morphology based spell checker). To develop morphology based spell checker, the knowledge of the language morphology is necessarily required. Accordingly, the morphological properties of Afaan Oromo have been studied. To the best of our knowledge, this work is the first of its kind for Afaan Oromo. The methodology delineated in the paper can be replicated for other languages showing similar morphology with Afaan Oromo.

Abstract: Face recognition has been one of the most interesting and important research fields in the past two decades. The reasons come from the need of automatic recognitions and surveillance systems, the interest in human visual system on face recognition, and the design of human-computer interface, etc. The rapid development of face recognition is due to a combination of factors: active development of algorithms, the availability of large databases of facial images, and a method for evaluating the performance of face recognition algorithms. The system covers any departments, agencies or companies which require personal identification and security to their employees. The face recognition system covers multiple face photos, matching of faces, head rotations, detects 66 facial feature points (eyes, eyebrows, mouth and nose) and all data are placed in a database. Additional enrolments will be required upon various changes in registered faces. The said system only limits to personal identification which contains certain fields about the registered user, it cannot detect the skin color and age of a person and the system is not a video- based face recognition system. This system does not expect to solve all the issues in face recognition, such as extreme facial expression, wearing on the face, great age discrepancy and extreme lightning condition and without frontal face information.

Abstract: India is a developing country and electrical energy consumption by industries is about 60% of the total energy consumption. The industrial development in the country is progressing at a fast pace due to the increase in the number of industries, the gap between demand and supply of electricity is also increasing day by day. To minimize this gap the best solution is to conduct an energy audit of all industries on regular bases. The energy audit will determine energy wastage and losses, and provide techniques and ways to minimize the losses. The energy consumption techniques suggested by the energy audit will not only minimize the losses but also reduce monthly electricity bill. This paper suggests ways and means to conduct an energy audit in an industry.

Abstract: Transient mixed convective airflow in a novel Building Solar Chimney, designed in connecting together, as a single device, a Photovoltaic/Thermal (PV/T) collector with transparent PV cells as active wall and a solar thermal flat-plate collector, has been analyzed numerically using a stream function, vorticity formulation and employing a finite difference scheme. The Photovoltaic-Thermal Building Solar Chimney could not only generate electricity but also achieve potential energy saving by the reduction of the air conditioning cooling loads when it is applied in tropical climate conditions. The results are presented in the form of streamlines, isotherm contours, local Nusselt number, mass air flow characteristics and the dimensionless temperature. The effects of Grashof and Reynolds numbers and the geometrical parameters on the performances of the Building Solar Chimney are presented and analyzed. Based on the resulting numerical prediction, it is found that the Photovoltaic/Thermal Building Solar Chimney (PV/T-BSC) model offers a good electrical efficiency while Photovoltaic/Thermal Reverse Building Solar Chimney (PV/T-RBSC) collector offers a good thermal efficiency. Finally, the results showed that no Building Solar Chimney studied can simultaneously provide good electrical and thermal efficiency.

Abstract: Pine trees cover large portions of the Himalayan region and are considered a hazard to cultivation and agriculture as well as the environment. This is because during the summer season, dry pine needles fall from the trees and cover the forest floor. Not only is this detrimental to cultivation, and the growth of grass needed as fodder for livestock, this is also a serious cause of uncontrolled frequent forest fires during the dry months. The focus of this study is to research alternate uses of these dry pine needles, including energy generation, which would result in an economic boost to the region. It would also greatly reduce the risk of forest fires, and therefore be of value from an environmental point of view

Abstract: Due to the increasing demand of potable water in many locations around the world, the sea water desalination is now one of the main sources of supplying potable water. The main problem facing water desalination is the energy consumption needed by water desalination process. The depletion of the fossil fuel and its continuous increasing cost accompanied with the increasing demand of potable water, make the problem of supplying potable water more sophisticated. With the continuous decrease of the prices of the PV modules, it is becoming more attractive economically to design a Reverse Osmosis (RO) water desalination system using Photovoltaic (PV) system and it’s friendly to environment if compared to fossil fuel impact. Using RO water desalination technique for desalinate sea water with high salinity (up to 45,000 ppm) into potable water. Instead of depending on conventional fossil fuel, the proposed system depends on solar energy in supplying energy, specifically photovoltaic (PV) systems. In this work a system design and cost analysis for RO Water desalination system powered by PV system without, with storage batteries and hybrid system using diesel fuel are presented. Regarding to low efficiency and lifetime of batteries which that should be replace every four years and it’s expensive prices, the main concept is using water desalination system working during days time with a large array size without batteries storage or diesel fuel in order to reduce total system cost . Optimality criterion is the cost per M^3 of desalinated water.

Abstract: Urban growth modelling cellular automata has blossomed due to the advancement in geographic information systems (GIS), remote sensing and computer technology. Among such urban growth models, our urban growth model (UGM), was modified from SLEUTH (Slope Land-use Transport Hill-shade) model. UGM has been integrated in the XULU modeling frame-work (eXtendable Unified Land Use Modelling Platform). In this research we evaluated a modified UGM whose transition rules were modified. In order to arrive at urban growth modelling, we used multi-temporal Landsat satellite image sets for 1987 and 2010 to map urban land-use in Nyeri. We compared our results with a normal UGM simulation. Thus, we arrived at two urban growth simulations for Nyeri in order to get a better glimpse of land-use system dynamics. Both models were calibrated and urban growth simulated until the year 2030 when Kenya plans to attain Vision 2030. Observed land-use changes in urban areas were compared to the results of both UGM models for the year 2010. The results indicate that the two models resulted in urban growth in different directions and magnitudes. This approach is useful to planners as it gives the scenarios of using different transition rules of a cellular automata model in urban growth modelling.

Abstract: The important step in the turbine aerodynamic design is generation of blade element profiles to achieve the required flow deflection and smooth flow acceleration with minimum losses. During profile generation, in addition to aerodynamic performance, additional constraints of thermal, structural and castability requirements need to be considered. Thus profile generation is a trade-off between contradicting requirements of aerodynamic performance, thermal and structural performance. In the present study, a method for profile generation based on Bezier curves is developed to meet the above conflicting requirements. These profiles are analyzed for the flow field using a commercial 3D N-S code for design and off-design conditions. These profiles are also tested in 2D transonic cascade tunnel. The profile pressure loss coefficient, blade exit angle and blade surface isentropic mach numbers are compared between CFD and test results.

Abstract: The Web is an incredible informative media, but its same success has turned it into a two-sided phenomenon. On the one side, it has got plenty of information, a richness of contributions and data that is unprecedented in the history of humanity. On the other side, the sheer size of the information present in the Web make it hard to access and to use at all levels, humans and computer-based. In this paper we present a high level perspective on this two-sided nature of web information, by introducing the general concept of Trust Scenario and see its implications by defining major axes of information, and the corresponding directions they can lead to in the future of the Web.

Abstract: 122 patients with osteoarthrosis, who had verified chronic gastritis in the anamnesis (50 males and 72 females), aged from 42 to 64, were examined. Control group included 40 patients with osteoarthrosis without gastroduodenal zone pathology in the anamnesis. For arthralgia relief, patients were prescribed to intake meloxicam (average dose — 12.5±1.39 mg/day) or nimesulide (average dose — 150±14.91 mg/day). As a result of this research, it was determined that prescription of selective NSAIDs (meloxicam and nimesulide) raised the risk of NSAIDs gastropathy/dyspepsia in 2.9 times (P<0.03) in patients with chronic gastritis in the anamnesis than in patients without associated gastroduodenal zone pathology. Atrophy of gastric mucous membrane was associated with higher risks (P>0.05) of erosive gastropathy. With the purpose of gastropathy prevention upon taking NSAIDs, patients with chronic gastritis in the anamnesis are recommended to undergo gastroprotective therapy.

Abstract: This paper presents Black-Scholes partial differential equation in the Mellin transform domain. The Mellin transform method is one of the most popular methods for solving diffusion equations in many areas of science and technology. This method is a powerful tool used in the valuation of options. We extend the Mellin transform method proposed by Panini and Srivastav [7] to derive the price of European power put options with dividend yield. We also derive the fundamental valuation formula known as the Black-Scholes model using the convolution property of the Mellin transform method. 2010 Mathematics Subject Classification: 44A15, 60H30, 91G99

Abstract: Customers queue up at the Nigerian National Petroleum Corporation (NNPC) mega stations to purchase the Premium Motor Spirit (PMS), Dual Purpose Kerosene (DPK) and Automotive Gas Oil (AGO) popularly called petrol, kerosene and diesel respectively in the country. The PMS usually has the highest demand due to its various uses, and the queue for the product at NNPC Mega station during period of scarcity (referred to here as peak periods) has varying average arrival rate at various time of the day. The waiting situation is exasperating to the customers and the management. Thus an operational plan module for determining basically the optimum number of active servers to salve the queue problem in the Stations, while attending to vehicles with minimum demand of 10 litres of PMS was developed. The following optimal active servers were obtained and recommended for the corresponded arrival rate of 1 car per minute to 4 cars per minute, at 72- 80% system utilization rate, a known average service rate of 0.457 cars per minute and average waiting time of 2.6954 minutes to 0.9737 minutes. Simulation of the system was done generating a model which suggests optimum number of server given arrival rates and average service rate.

Abstract: This study observes an empirical correlation of energy utilization and economy increase in Kazakhstan using time fraction from 1993 to 2011. To specify, utilization of electricity and the electricity that is produced from oil and gas sources correlation had been observed as well. Co-integration method and Granger causality of Hsiao were applied in order to come up with unidirectional causes of economic growth on total energy consumption. The economic growth facilitates raise in gas energy production as well. For the energy conservation policy it suggests to remove energy saving policy from gas-energy sector to oil sector as we reject any causality correlation of increase in economy and production of oil and energy. Furthermore, policy makers should sustain technological innovations in electronic sectors, which will increase consumption of the electricity by the population and this will finally cause economic growth.

Abstract: This is an empirical analysis which depicts the preference significance of private commercial banks to establish the importance of various criteria that attracts the young customers. In here, this study segregates the different criteria which are significantly more important in inspiring selection over time and those which have been considerably less important. For this study, sample size was 1200 consumers aged 18-30 years of different university students, young entrepreneurs & professionals in Bangladesh. Mean, Std. Deviation and ANOVA have been used for the detail analysis of the data set. The important features of determining their bank selection are: Availability of ATM in several locations, bank’s reputation, paying highest interest rates on savings accounts, friendliness of bank personnel, low services charges and confidence in bank management. Gender differences do not play the vital role for the selection attitudes of bank and bank services as well. In particular, findings advocate that male and female customers as distinctive segments with various precedence may be important for their bank selection process. Commercial banks should take the appropriate marketing strategy for attracting the new customers specially the young generation which will motivate them to select bank as their potential service provider.

Abstract: this research presents firstly the forest activity in Congo and secondly, some forest certification schemes exerted in Africa and in Congo, and explain how the Congolese government and these systems work together for a sustainable management of forest ecosystems in Congo. To do that we put the action on the involvement and the role of the Congolese government in this relationship. Congo is one of the countries that have always shown their will to sustainably manage their forest resources. The first forest management in Congo started in the early 1970s with the development of management plans focused on annual timber harvesting In 1974, the new Forest Code (Law No. 004/74 of 4 January 1974) transformed the Congolese forest legislation. Considered at the time of its promulgation as one of the most modern forest code in Central Africa, it defined the forest management unit (UFA), the maximum annual cut (VMA), the promotion of local processing, Atlas Forestier Interactif du Congo[2]. At present, the use of the forest domain is governed by Law No. 16/2000 of 20 November 2000 on the Forest Code [4].It takes into consideration that, go one hand, developments related to forest management and conservation of the environment occurred in recent years at the international level and, on the other hand, the new socio-political context of the Congo. The Forest Code confirms the policy of sustainable management of forest ecosystems, which guarantees sustained forest products production and ensures the conservation of biological diversity. In addition, the law stipulates that the transformation of the country's production should reach 85 percent Despite those efforts granted by the Congolese government, Congo still lacks sufficient operational schemes certification, so it is still an exclusive business to northern markets. The Congolese government has the merit to generate debate involving in the forest sector regarding the certification.

Abstract: Research on the major risk factors for traditional projects is abundant; however, despite research citing increased communication and trust issues in virtual environments, research on the major risks for projects conducted in virtual environments is scarce. This paper addresses that void by reporting on a research study of virtual project risk that culminated in a survey of 107 virtual project management practitioners from throughout the United States. Prior literature, in-person interviews and a focus group were used to develop a comprehensive list of fifty-five potential risk factors. Survey participants were asked to rate each of these potential risks, by considering the degree of impact it had on the successful completion of a recent virtual project in which they participated. Similar to past surveys focused on traditional software development projects, the goal of this research was to identify a set of major virtual project risks, those risks most likely to have the greatest impact on the successful completion of a virtual software development project. The results of this study will benefit project management practitioners in managing risk in a virtual project environment.

ABSTRACT: The methanol extract of an edible mushroom, Pleurotus highking with its whole parts, cap and stipe individually were subjected for the evaluation of antimicrobial activities against a series of pathogenic microorganisms. Three Gram positive (Bacillus cereus, Streptococcus agalactiae and Agrobacterium), three Gram negative (Pseudomonas aeruginosa, Escherichia coli and Shigella dysenteriae) and three pathogenic fungus (Aspergillus niger, Saccharromyces cerevaceae and Candida albicans) were used as test pathogen. Disc diffusion assay method was employed for our experimental purpose. All the tested Gram positive strains were sensitive to 200μg of extracts/disc while there was no sensitive to Gram negative strain, Escherichia coli and Shigella dysenteriae. A tested Gram negative strain, Pseudomonas aeruginosa also sensitive to the extracts at a concentration of 200μg/disc. Aspergillus niger and Candida albicans were susceptible to methanol extract of Pleurotus highking while Saccharromyces cerevaceae was resistant to it. However, the susceptibility of the extracts from different parts was varied. The extract from cap showed prominent antimicrobial activity as compared to whole mushroom and stipe.

Abstract: Drive, engagement, and passion are more important than one’s talent for professional success. This is how David Maister sees the idea of professionalism. In his article “Are You Having Fun Yet?” (Maister, 2007) the author practically worships the idea of importance of loving what you do instead of forcing yourself to do it. He also finds the difference between the job and career. This is, to David Maister’s opinion, the starting point for changing tiresome and exhaustion from work into satisfaction. Nowadays, we live in the globalized world of information and technology where the competition is intense and there is an ever-growing pressure on organizations and workforces to deliver continuous improvement in products, systems and processes. In this constantly demanding world, it is really questionable whether a persistent employee motivation is possible at all, and whether one may ever enjoy what he is doing. More intriguing part is that employee motivation does not directly relate to any single aspect of the job viz. job type, income, position or industry. Highly paid lawyers and investment bankers seem to be no happier than dustmen or orderlies. As the job satisfaction numbers are in consistent decline during the past two decades (Gibbons, 2010), employers in today’s world are facing a clear and present issue – what can the administrative leadership do to keep employees motivated, engaged and happy.

Abstract: The problem of impact of particulate matter on vegetation is quite complex. Relatively little attention is given to the effect of particulate matter on different tropical plants, compared to the effect on tropical animals. A comparative study aimed at showing the effect of asphalt particulate matter on the anatomical characteristics of some tropical plants was carried out. Samples from three plant species namely: Manihot esculentus Crantz (Cassava), family Euphorbiaceae; Musa paradisiaca L. (Plantain), family Musaceae; and Alchornea cordifolia (Schum. & Thonn.) Mull. Arg. (Christmas bush), family Euphorbiaceae, were collected from two sites designated as non-polluted site (Site 1), and asphalt polluted site (Site 2). Plant materials were fixed in FAA (Formalin: Acetic acid: alcohol) solution immediately after collection. For anatomical studies, free hand sectioning method was used, and photomicrographs of good sections taken with a Leitz Diaplan photomicroscope fitted with Leica WILD MPS 52 camera. The results showed that there was significant increase in the number of vascular bundles from plant samples collected at the polluted site. Possibly, this may be one of the adaptive features by these plants to reduce damage caused by asphalt particulate matter. However, the cortex, the epidermis, and pith tissues were unaffected and seem to be resistant to asphalt particulate matter. From the present study, it is apparent that the vascular bundles are more affected compared to other tissue systems. In other words, they are more sensitive to pollutants than other tissues. The different tissues of the same plant species differ in their responses to the same pollutant. This is a clear indication that particulate matter exercised a decisive influence on the different anatomical plant features

ABSTRACT: The paradigm of government still has not undergone a fundamental change, which the old paradigm is still evolving. It is characterized by the behavior of state officials in the bureaucracy that still sees himself to be served rather than to serve. This condition is exacerbated by the fact that the capacity of Government officials in the public service (public service) is almost always problematic. It looks at the process of delivery that does not comply with the commitments, which are not standard services, the uncertainty of the time, not transparent, covered up, convoluted, heavy handed, less responsive, impractical, inefficient, and financing that does not make sense (unreasonable). All it seemed to have become a phenomenon which is too attached to the apparatus whose job it is serving the community. The phenomenon of bureaucratic behavior can be examined by using a behavioral approach to bureaucracy according to Weber, namely transparency, professionalism, responsiveness, and impersonality. This study aimed to describe the behavior of the bureaucracy in the service of the issuance of location permit (SITU), Trading License (License), Building Permit (IMB) at the Office of Licensing Services Parepare. This study used a qualitative approach with descriptive qualitative research as a method of solving problems of this study. This study uses in depth interview techniques, observation and documents. Data were analyzed through the stages of data reduction, data presentation, deduction and verification. The results of this study indicate that the licensing service in the City of Pare-Pare is determined by the role of the bureaucracy which includes officials and organizations within the scope of the government bureaucracy and authority. Bureaucracy that appears in the license service if viewed from the aspect of transparency, responsiveness, professionalism, and impersonal still not optimal.

ABSTRACT: One of the natural antioxidant sources is turmeric olant from zingiberaceae family that contains curcumin. Curcumin is an important component isolated from turmeric (Curcuma longa), that is used as traditional medicines and food additive substance. This study was aimed to examine the use of turmeric as an antioxidant in repeatedly used cooking oil and to find out the mechanism by which the turmeric extract inhibits the formation of trans fatty acid in repeateadly used cooking oil. This study was an experimental study in which the turmeric extract was obtained by maceration. The obtained turmeric extract was then added into cooking oil that will be used later to fry repeatedly for 10 times. Frying treatments consisted of frying without turmeric extract addition (control) and frying with turmeric extract addition at concentrations of 0.02%, 0.03%, and 0.04%. The samples of the used cooked oil were collected at frying 1, frying 5, and frying 10 and analyzed for their trans fatty acid content by gas chromatography. Study findings indicate that turmeric extract addition into cooking oil reduced the formation of trans fatty acid and extended the use time of cooking oil. According to trans fatty acid content analysis, the best treatment was the addition of turmeric extract at concentration of 0.03%.

Abstract: The antibacterial activity of three plants extract Abrus precatorius, Croton penduliflorus (Seeds) and Nauclea latifolia (Root) were evaluated in an in vitro test on Escherichia coli, Klebsiella pneumonia and Enterococcus faecalis. Twelve extracts consisting of hot ethanol, cold ethanol, hot water and cold water were prepared. They were tested using the agar diffusion method. Efficacy was assessed by measuring the diameter of zone of inhibition around the colonies on Muller Hilton agar medium. E.coli showed the highest susceptibility to all plant extracts this was followed by E. faecalis. K. pneumonia showed the least susceptibility to all the extracts. Across board, the cold ethanol extracts of the plants showed the highest susceptibility while the other extracts exhibited variable antibacterial activities. The minimum inhibitory concentration (MIC) of the eight most active extracts ranged between 3.025mg/ml to 50mg/ml while minimum bactericidal concentration (MBC) was between 6.25mg/ml - 25mg/ml. Commonly used antibiotics such as Augmentin and Amoxillin showed low sensitivity as compared to the extracts with varying inhibition zone of 0-4mm Phytochemical screening of these extracts showed that flavonoid was detected in only A. precatorius, Glycoside was found in all extract except in C. penduliflorus extracts. Alkaloid, saponin and Tannin were found in all the plant extracts. This invitro study demonstrated that folk medicine in addition to being cheaper could be effective as modern medicine in combating pathogenic microorganisms.

ABSTRACT: The paper seeks to identify risk factors associated with STIs and its prevalence in western Ghana. This study explored the relationship between STI diagnosis and demographic factors as well as contraceptive use in a mining community in western Ghana. Selected hospitals in the district were surveyed. The sample consisted of 117 males and 253 female patients attending outpatient clinics. 92% of 400 individuals approached agreed to complete a questionnaire. The majority (72%) of the respondents was between 20-39 years; 14% were adolescents; 94% had some form of education, of which 43% had completed middle school; 50% of males and about 80% of females were married. Use of contraceptives by married and never married was 57% and 43%, respectively. The vast majority of males were engaged in small scale mining; 42% of the women were into trading. About 11% had gonorrhea, 27% had candidiasis and only 1 had chlamydia. Of the 150 respondents who had STIs, 84% were females. The odds of an STI diagnosis significantly increased when respondents were female (odds ratio (OR) = 3.0) compared to males and younger respondents (19-24 years) compared to older ones (OR = 3.68). Odds decreased with use of contraceptives (OR = 0.56) compared to non-users and with marital status (OR = 0.42) compared to never-married. The overall logistic model was statistically significant (χ2 (8, N=370) = 56.19, p < .001). Females, younger individuals, never-married and contraceptive non-users are at relatively high risk for STIs in a mining district in western Ghana.

Abstract: Exposure of workers to waste anaesthetic gases in the operating and recovery rooms of hospitals is of concern because of the reported adverse effects of such gases on the health of personnel in this occupational group. Objectives To determine the effect of inhaled anesthetics gases on health staff health status (headache and dizziness). And to find out the association between the effects of inhaled anesthetics gases on health staff health status and their demographic data and job related data. Methodology, A Case-Control study is carried out in Al-Najaf Health Directorate / Al-Sadder medical city, from June 1st, 2013 to September 1st, 2013. A probability stratified sample of (29) from health staff personnel working in the operative rooms selected as a study group, and (13) from health staff personnel working in the other hospital wards selected as a control group, were included in the study. The data are collected through the use of semi-structured questionnaire, which consists of three parts including, demographic and job related data, data about headache characteristics, and data about the dizziness characteristics. Results and Conclusions The study results indicate that the health staff in operative rooms are more prone to have a headache and dizziness than those who working in other wards. And that there is a significant effect of the work place and the job title on the suffering of headache and dizziness among operative room health staff. Recommendations, The researchers recommend a further studies should be employed to involve a large number of health staff with a national level. An education programs should be focusing on how to manage these gases to reduce its effects on health staff health status.

Abstract: A comparative study was carried out to show the effect of particulate matter generated from asphalt on the phytochemical content of plant species in the environment. Asphalt is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It is primarily used in road construction and also for bituminous waterproofing products. Samples from the following species: Manihot esculentus Crantz (Cassava),family Euphorbiaceae, Musa paradisiaca L. (Plantain), family Musaceae, and Alchornea cordifolia (Schum. & Thonn.) Mull. Arg. (Christmas bush), family Euphorbiaceae, were collected from asphalt polluted and unpolluted environment. For localization of calcium oxalate crystals and silicon, fresh stems, leaves and petioles of plant specimens were fixed in FAA (formalin, acetic acid and absolute ethanol) solution in the ratio 1:1:18 respectively. Specimens were rinsed in several changes of water and hand-sectioning method was used. For calcium oxalate crystals, sections were stained with an equal mixture of 5% silver nitrate and 30% hydrogen peroxide under an intense light which was supplied with a 60-watt electric bulb kept at a distance of about 20cm from the slides. The staining took place for about 30 minutes at 10 minutes interval. For Silicon localization, sections were covered with methylene blue and sufficient heat was provided, and then cleared with clove oil and mounted in glycerin. Tannin localization was carried out using the fixative stain method. Specimens were placed in a fixative stain containing a solution of 20ml of 10% ferrous sulphate with 100ml of 4% formaldehyde. They were rinsed in several changes of distilled water and free-hand sectioning method was used. A reduction in the content of tannin, calcium oxalate crystal, and silicon in the highly polluted site as compared to the unpolluted site was recorded. Growth of plants in the polluted site was found to be affected by asphalt particulate matter, which might be due to the presence of different toxic pollutants in asphalt dust. The plants are exposed to both biotic and abiotic stresses which are detrimental to plant health and metabolism.

Abstract: Empirical evidence from many parts of the world indicates that, intercropping, on a long – term basis, results in depletion of soil fertility and attendant reduced crop yields. Thus, the need arises to critically assess changes in nutrient status of soil under intercropping, in order to be able to fashion out an adequate fertilizer package, involving addition of organic and/or inorganic fertilizers to replenish the lost nutrients, hence, making intercropping sustainable. To partly meet the need, a two – year study was designed to evaluate the influence of yam – based intercropping on changes in fertility status of an Alfisol, tuber yield and yield components of white yam (Dioscorea rotundata Poir). The experiment was carried out at the Teaching and Research Farm of the Ekiti State University, Ado – Ekiti, Ekiti State, Nigeria, during 2012 and 2013 cropping seasons. The experiment was laid out in a randomized complete block design with three replications. The yam – based intercropping included: sole cropped yam (SCY), which served as the control; yam/cowpea (YC); yam/maize (YM); yam/cassava (YCa); and yam/maize/cassava (YMCa). The results obtained indicated existence of significant (P = 0.05) differences among the yam – based intercropping systems as regards their effects on chemical properties of Alfisol and yam tuber yield and yield components. At the end of 2012 cropping season, yam – based intercropping resulted in significant (P = 0.05) decreases in soil organic carbon (SOC) from 0.68 g kg-1 for SCY to 0.58, 0.52, 0.46 and 0.39 g kg-1 for YC, YM,YCa and YMCa, respectively. Similarly, at the end of 2013 cropping season, yam – based intercropping resulted in significant decreases in SOC from 0.64 g kg-1 for SCY to 0.55,0.48, 0.42, and 0.35 g kg-1 for YC, YM, YCa and YMCa, respectively. At the end of 2012 cropping season, yam – based intercropping significantly decreased total nitrogen from 0.50 g kg-1 for SCY to 0.55, 0.38, 0.44and 0.32 g kg-1 for YC, YM, YCa and YMCa, respectively. At the end of 2013 cropping season, yam – based intercropping significantly decreased total nitrogen from 0.47 g kg-1 for SCY to 0.52, 0.34, 0.40 and 0.27 g kg-1 for the respective YC, YM, YCa and YMCa. Across the two years of experimentation, mean values of yam tuber yield, adduced to yam – based intercropping systems were 7.00, 7.16, 5.94, 5.46 and 4.12 t ha-1 for the respective SCY, YC, YM, YCa and YMCa
