ABSTRACT:The objective of this study was to evaluate the impact of ground water (wells) quality on soil properties and okra (Abelmoschusesculentus) productivity under Khartoum state conditions, Sudan. The experiment was organized in a complete randomized design with three replicates. Samples of groundwater and soils nearby the water source were taken from: Khartoum, Khartoum North and Omdurman. The measured parameters for both water and soil were K, Na, Ca, Mg, CO3, HCO3, SO4, pH and EC, as well as crop yield (kg/ha). Chemical analysis showed that the level of different constituents of ground water at the three locations was conforming to FAO standards for irrigation water except SAR which was found higher than the standard. On the other hand there were significant differences (P < 0.05) among them. Khartoum North recorded the highest values of pH, EC, HCO3 and SAR, while the lowest values of (SAR and EC) and (pH, HCO3 and SO4) recorded with Khartoum and Omdurman, respectively. The soil analysis revealed that the ground waters have noticeable effect on soil chemical properties. Whereas, Khartoum North revealed the highest values of pH and EC, while the lowest values of EC were recorded in Khartoum. The amounts of yield as collected from Khartoum, Khartoum North and Omdurman were 384, 288, 324 kg/ha respectively. The values of yield loss per unit of` salinity were found to be 71.52, 36.24 and 21.84 kg/ha/ds/m for Khartoum, Omdurman and Khartoum North, respectively. Hence, it was concluded that the groundwater in Khartoum state has slight variation in quality from location to location inside the state.

ABSTRACT : Pregnant women need adequate nourishing food for the foetus to develop well else, they experience low birth weights and diet related non-communicable diseases. Hence, they will transfer the disadvantages of malnutrition in their own lives to the next generation. Majority of the pregnant women in Buikwe are illiterate, have low incomes and lead miserable lives. Improving diets of these marginalized women requires looking into their natural resource biodiversity to find affordable and sustainable solutions. This study investigated the wild edible plants (WEPs) consumed by the pregnant women in Najjembe sub-county, Buikwe district. It also considered the preparation methods, forms of consumption, knowledge sources, collection sites and constraints to domestication and commercialization of WEPs. An ethnobotanical approach was used and through convenience sampling the respondents were recruited and data collected. Data were analysed using descriptive statistics facilitated by SPSS version 16. Sixty two WEPs were reportedly consumed by the respondents most frequently consumed being; Amaranthus dubius Mart. Ex Thell., Psidium guajava L., Solanum anguivii, Cleome gynandra L. and Mangifera indica L. Traditional methods of cooking were used in the preparation of WEPs. Majority of the reported WEPs comprised fruits and vegetables. Indigenous knowledge on WEPs was mainly obtained from parents and relatives. Radios were reported to play a big role in publicizing the values of WEPs. The wild was the major collection site for WEPs and some species were seasonal. Lack of germ plasm, slow germination rates, low yields, ignorance, lack of land and marginal markets are the major constraints hindering commercialization and domestication of WEPs. There are no serious regulations governing collection of WEPs from the wild. A diversity of WEPs exists in this area and if properly utilized by the pregnant women, they can tremendously improve their dietary quality and quantity.

ABSTRACT: Gilgel Abay watershed is densely populated causing various effects on resource bases like deforestation, expansion of residential area, and agricultural land. The watershed is also facing high erosion by the effects of intense rainfall of the watershed, which aggravates the land cover change of the watershed. This study was designed at application of SWAT for the assessment of impacts of land use land cover change and best sediment management practices that are related to hydrology/stream flow and sediment yield of the watershed. The land use land cover change analyses were performed using ERDAS Imagine 2014 that was used for further analysis of SWAT. Land use land cover changes for three different years of 1986, 2000 and 2011 land use scenarios with different management practices were used for estimation of stream flow and sediment yield. During the study period most parts of the grassland and shrub land were changed to cultivated land. An increase of cultivated land by 33.79% over 25 years period (1986 – 2011) resulted an increase of stream flow and sediment yield by 5.87m3/s and 62.78t/km2 respectively. The Nash Sutcliff efficiency, coefficient of determination (R2) and RSR were used for evaluating the model performance. Spatial variability of sediment were also done using the validated sediment yield results of 2011 land use on Arc GIS. Hence, for the critical sub- watersheds the design and development of best management practices were performed. Three BMPs (best sediment management scenarios) S1 (filter strip), S2 (stone bund) and S3 (reforestation) were considered in this study. The results has showed a decrease of sedimentation by 24.73%, 21.36% and 36.18% sediment yield reductions implementing S1, S2 and S3 respectively. Therefore practicing S3 for Gilgel Abay watershed should be implemented and encouraged for efficient sediment reductions.

ABSTRACT: Lanthanum Oxalate decahydrate and Copper ferrites were prepared by chemical and sintering process respectively and the detailed investigation of their properties was carried out successfully at room temperature by FTIR,XRD,SEM ,TEM as well as by chemical methods. Catalytic activity of copper ferrite over the decomposition of lanthanum oxalate was studied non isothermally by TG-DTA after mixing the former with the later in varying mole ratios. Also a physical mixture of CuO and Fe2O3 was prepared for comparative study. It is found that CuO has catalytic activity whereas Fe2O3 behaves as negative catalyst for the entire process. But the physical mixture enhances the rate of reaction at the low temperature and as the temperature becomes high the solid solution of copper ferrite is expected to be formed by valence induction generating n- type semi conduction in Fe2O3 resulting in a ferrite having inverse spinel structure and having high rate constant. There is no appreciable change in activation energy during the process. It is inferred that the catalytic activity appears to be a function of semiconducting property of the copper ferrite. The formation of ferrite at high temperature is diffusion controlled best fitting third order law decomposition of Lanthanum Oxalate. The mechanism of decomposition has been proposed.

ABSTRACT: Bioenhancers are substances that increase the bioavailability and the uptake of drugs in combination therapy. It has been found that cow dung, cow urine and its distillate also possess bioenhancing ability. They act through several mechanisms of action affecting mainly absorption process, drug metabolism or action on drug-target. Drugs from the plants are easily available, less expensive, safe, and efficient and rarely have side effects. In the present study we investigated, the bioenhancing role of cow urine on antibacterial activity of organic extract of leucas aspera Linn, Antibacterial activity of organic fraction alone and in the combination of cow urine was determined against Xanthomonas campestris pv citri. All extracts and fractions were effective and showed 7 mm to 14 mm zone of inhibition. The Chloroform extract (12 mm) and cow urine extract (14 mm) showed great antibacterial activity. The antibacterial effect cow urine combination of extract was higher than the inhibition caused by extract alone and is suggestive of the bioenhancing role of cow urine. Results of Minimum Inhibitory Concentration (MIC) Alcohol and aqueous extracts had lowest value 5.55 µg/ml while highest 16.85 µg/ml shown by Ethyl acetate extract respectively. The cow urine extract had 6.15 µg/ml. Phytochemical analysis revealed the presence of secondary metabolites like alkaloids, flavones, steroids, flavones, tannins, terpinoids, quinines, phenols, steroids, phlobotanins and glycoside. These results indicate that the cow urine has antimicrobial activities, which supports the claim of traditional practitioners. Further studies on mechanism involved in bioenhancing effect of cow urine are under investigation.

ABSTRACT: Higher education and technical training institutions around the world are increasingly turning to e-learning as a way of dealing with growing and changing student populations. Factors affecting e-learning cover a broad spectrum of categories but are not conclusively defined and researched, and the relative importance of which is not clearly understood. This study sought to establish user friendliness indices affecting adoption of e-learning by TIVETs. The study used survey research design. A sample of 385 respondents was obtained from five selected TIVETs. Each of the TIVETs contributed 77 respondents to the study. Of these 77, 7 of them were teachers or instructors while the rest 70 were students or learners. Simple random sampling method was used to select students/learners and teachers/instructors at the TIVET level. The total study sample was therefore 385 respondents. A structured questionnaire was used for data collection. Descriptive statistical tools were used to analyze data. Descriptive statistics included mean scores, percentages and frequencies. The results show that majority of the teachers used face-to-face learning and few used e-learning. A significant proportion of the teachers indicated they do not use e-learning at all. This shows that e-learning is not fully integrated in TIVETs. This could be attributed to the e-learning systems in place that do not seem to address the needs of students and teachers. According to the students or learners, an e-learning system should be easy for them to learn and operate and be skillful; should be easy for them to get it to do what they want to do; generally student should find it easy to use; should adapt to the device and display in use (responsiveness); interface should be intuitive (user centric) and efficient; and it should allow information to be readily accessible to students and easy to find. The findings show that access to e-learning is low for students and teachers in TIVETs. This is due to a combination of factors key among them attitude of students and teachers towards use of e-leaning, interruption, and usability of available resources. All these are informed by user friendliness indices of e-learning system. This study concluded that technical training institutions have not adopted e-learning despite its obvious advantages. The little the TIVETs have tried towards adoption of e-learning, user friendliness of the systems they have created is poor. User friendliness of an e-learning system is a critical element for students/learners and teachers/instructors. The user friendliness indices affecting adoption of e-learning include ease of use, reliability, efficiency, memorability, errors and satisfaction. This study recommends that TIVETs should adopt e-learning to tap into advantages associated with this method of learning. TIVETs should work in collaboration with teachers and learners to ensure e-learning that they adopt is user friendly hence useful to both the students and learners. Teachers and learners should support their TIVETs in developing an e-learning system that suits their learning needs.

Abstract: Logic compatible gain cell (GC)-embedded DRAM (eDRAM) arrays are considered an alternative to SRAM due to their small size, nonratioed operation, low static leakage, and two-port functionality. However, traditional GC-eDRAM implementations require boosted control signals in order to write full voltage levels to the cell to reduce the refresh rate and shorten access times. These boosted levels require either an extra power supply or on-chip charge pumps, as well as nontrivial level shifting and toleration of high voltage levels. In this brief, we present a novel, logic compatible, 3T GC-eDRAM bitcell that operates with a single-supply voltage and provides superior write capability to the conventional GC structures. The proposed circuit is demonstrated with a 2-kb memory macro that was designed and fabricated in a mature 0.18-µm CMOS process, targeted at low-power, energy-efficient applica-tions. The test array is powered with a single supply of 900 mV, showing a 0.8-ms worst case retention time, a 1.3-ns write-access time, and a 2.4-pW/bit retention power. The proposed topology provides a bitcell area reduction of 43%, as compared with a redrawn 6-transistor SRAM in the same technology, and an overall macro area reduction of 67%including peripherals.

ABSTRACT : This paper presents the comparative study of DC-DC converters employed for standalone solar powered panel for single-phase supply. Presently, MNRE (Ministry of New and Renewable Energy) India, is compulsorily reducing the carbon footprint generated by production of electricity by incorporating the photovoltaic panel at every level. Increased demand of photovoltaic panel and its accessories needs to be efficient and must be economical. As in standalone system, the photovoltaic panel is preceded by DC-DC converter and then in series with DC-AC converter. In this paper DC-DC converter is discussed with the modeling and simulation of Traditional Boost Converter (TBC), Swithced Inductor Boost Converter (SIBC) and Coupled Inductor Boost Converter (CIBC) with rated power supply for single-phase inverter. In many cases, roof top supply system has become popular for domestic supply but still partial shading, design element, rating of component according to power requirement is a big issue. TBC, SIBC, and CIBC are discussed mathematically and graphically and then simulated in MATLAB.

ABSTRACT: Nowadays, it is not questionable that the business environment of any organization is more dynamic and tumultuous. Therefore, it is indispensable to the organizations to formulate the distinguished strategy in order to triumph the competitive and turbulent business world. On the other hand, food business is more fragile and susceptible to the turbulent business world. In this essence, the purpose of this work was to formulate the strategies of a firm in food industry. In this study, the SWOT matrix, and Delphi method were used to evaluate the external and internal factors in order to establish more stable and profitable food business policy. By this study 39 experienced managerial personnel of 13 food business factories were employed in order to evaluate the different variables of each factor of Strength, Weakness, Opportunities and Threats. The expert’s evaluations were quantified by Likert Scale. There were indentified 35 variables of factors of Strength, Weakness, Opportunities and Threats. The less weighted variables were avoided from the SWOT matrix and strategy formulation. SWOT matrix was formed based on the prioritized SWOT variables with four quadrants; maxi – mini (ST strategy), mini – mini (WT strategy), mini – maxi (WO strategy) and maxi-maxi (SO strategy). Finally, it was hoped that this study will be a promising resource to any organization to overcome the external weakness and threats and also to plan their short term and long term business policy.

ABSTRACT: Environmental impact assessment (EIA) is a process having the ultimate objective of providing decision-makers with an indication of the likely consequences of their actions or the official appraisal process to identify, predict, evaluate and justify the ecological, social, and related biophysical effects of a proposed policy, program or project on the environment, while sustainable development is the maintenance of ecological integrity. The present study investigates the level of development in the city of Onitsha in Anambra State, Nigeria, to ascertain whether it is a sustainable development, using the tool of EIA and its implementation as a parameter. The instrument used for data collection included literature review, field survey using questionnaire distribution, interviews and personal observation. The result of the research showed that a lot of development have taken place in the city of Onitsha which include building of residential houses, shops, industries, petroleum filling stations, road constructions, hospitals and schools but these developments are not sustainable especially those of Onitsha South Local Government Area because the environment is not put into consideration. The key tool for sustainable development, which is EIA, is not used in the process of these developments mentioned above. From the statistical analysis collected and analyzed using mann-whitney test shows that there is a significant different between the project executed in this city using EIA and the ones executed without the use of EIA (P < 0.05). The consequences of this unsustainable development have resulted in environmental degradation, pollution, health hazards, erosion, excessive heat, over flooding and lost of the vegetation. To return to the path of sustainable development, there is therefore the need to go back to the use and implementation of EIA results provide by decision makers and the proper implementation of environmental laws and policies.

ABSTRAT: In recent development there has been great number of developments which reveal that some Police officers have been actively involved in a number of armed robberies in the country. There has been a report published on August 15/2013 from Ghana Myjoyonline.com, indicated that COP Prosper Agblor, Head of Criminal and Investigations Department of the Police Service berated the arrested officer for using his skills to harm society when it is meant to benefit it. He cautioned police officers to desist from such acts or face the full rigours of the law. Meanwhile, 108 officers have been dismissed from the Service between 2012 to June 2014, for various infractions. The management of the Service has also reduced the ranks of a 132 officers and 433 men and women are facing service enquiry. The study is to find out if criminal background is conducted on the new recruits before they are employed and if there is what method is being used, where the data about the individuals is gathered for the criminal background checks and which office under the Police service is responsible for the checking.

ABSTRACT: This project consists of a partial replacement of fine aggregate with stone dust and brick dust in cement concrete for rigid pavement. In this project I have added two types of admixtures named as brick dust and stone dust in cement concrete mix. Here brick dust and stone dust is added in cement concrete mix with a percentage variation of 5%, 10%, 15%, 20% and 25%. By adding brick dust and stone dust there was a variation in test results of compressive strength, flexural strength and tensile strength. The strength increased when the admixtures content increased up to 20% replacement in cement concrete. Now a day’s fine aggregate(sand) is very expensive; so that by adding admixtures like brick dust and stone dust as partial replacement in fine aggregate would give better saving and environment free. Therefore it is enhanced admixture to use in a rigid pavement construction in civil engineering and also overall cost may also reduce to 14.64% cost of cement concrete

ABSTRACT: Gender and socio-economic factors have been contributing significantly to the education and career choice of the young people in developed and developing countries. Nigeria is among the top countries in Africa which deeply embraced socio-cultural and religious beliefs that militate against sustainable educational development. This study aimed at evaluating the influence of gender and socio-economic indices on the youths’ choice of education and teaching as career after graduation. In addition to geographical inequalities, the influence of parents’ economic and educational attainment were the key factors mediating between the youths’ education and choice of career.The survey research methods including the stratified- random sampling procedure were adopted in collecting data for this study. Both the quantitative and qualitative statistical analyses were also employed for analysing the data and results. The findings further revealed that: the result of both the correlation(r= -0.999; p<0.000196) and regression (p<0.00000) showed that significant relationship existed among the six geo-political zones regarding the young people’s responses to choice of education/teaching as career after graduation.The geo-political zones and states in the southern region recorded more female students into education than as found in the northern region. It was also discovered thatthe choice of education/teaching field of study by the students was influenced by parents’ economic and educational background. There should be a further research to evaluate if other factors such as teachers role, peer groups and some other socio-environmental parameters have significant influence too in the youth’s education and choice of career in the country.
