BIOACCUMULATION OF HEAVY METALS AND HISTOLOGICAL CHANGES IN TISSUES OF MARBLE SPINEFOOT (SIGANUS REVULATUS) FROM THE SYRIAN COAST (EASTERN MEDITERRANEAN)
Get PDFThis study was carried out to determine the concentrations of tow heavy metals, copper (Cu) and lead (Pb), and histopathological lesions in tissues of Marble spinefoot Siganus revulatus (Forsskål & Niebuhr, 1775) caught from the Syrian coastal waters during 2019-2020. Results indicated tha the metals were accumulated in different tissues of siganus rivulatus by various levels, where, the non-edible parts accumulated more metals than the edible muscles. Cu and Pb concentrations in the fish muscles were lower the maximum permissible limit, however, Cu in the liver exceeded the permissible limit. Several histological alterations were observed in the muscles, including vacuolar degeneration in muscle bundles, balloon necrosis, Melano- macrophage centers, splitting of muscle fibers and atrophy of muscle bundles. The liver showed vacuolar dilation in blood vessels, leucocytes infiltration, thrombosis formation in hepatoportal blood vessels haemorrhage, haemosiderin and focal areas of necrosis. It was concluded that the environmental contamination of Syrian coast induced several histological alterations in the tissues of siganus rivulatus
STUDY OF THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF STEEL REBARS LOCALLY PRODUCED IN GHANA
Get PDFThe structural integrity of engineered structures depends highly on the materials used. In recent times, increase in the collapse of buildings in Ghana has allegedly been attributed to the poor engineering properties of locally produced steel rebars, an indication that they do not meet the requirements set by the Ghana Standards Authority (GSA). This project studied the metallurgy of different rebars randomly sourced in Ghana, with a view to determine their suitability for structural applications. The study involved determining the chemical composition of the various diameters of rebars, analyzing microstructure and mechanical properties of the rebars and the obtained results compared with GSA values. The diameters measured gave average values which were close to that of the standard values. The chemical compositions of the rebars were good as they were all within the mild steel range but a few noticeable inconsistencies were observed in the chemical composition. The average tensile and yield strength for the samples were 545.11 MPa and 453.55 MPa which were above the GSA values of 400 MPa and 300 MPa minimum respectively. The rebars were quite ductile as standards for both elongation and area reduction were exceeded. This showed that the selected rebars met the GSA standards
TRANSFER OF TECHNOLOGY AND NIGERIAN ECONOMIC DEVELOPMENT
Get PDFThis work is concerned with the effect of transfer of technology. The features of technology are determined by the nature of the economies for which they are designed. The most significant determinants includes the level of income of the recipient country, resources availability in the country, nature of the technology in use in the society, the following are the features of technology as they determine its resources use productivity and impact on production and consumption pattern. It was observed that the actual technology in use is thus circumscribed first by the nature of world technology, there by the nature of world technology, then by the availability of this technology to the country of known techniques and finally by the choice made among those available transfer of technology means the transfer of techniques in form of raw materials, plants, equipment, and knowledge from one country to the recipient (Host) country. Transfer of technology has created lot of opportunities and even wealth for Nigeria; however, it has also been observed that transfer of technology can also have negative impact on the country

THE CURRENT IRRIGATION POTENTIAL AND IRRIGATED LAND IN ETHIOPIA: A REVIEW
Get PDFA review of recent studies on irrigation water potential and irrigated land in Ethiopia was conducted from the historical point of view up to the present and the future. This review discusses Ethiopian current irrigation potential, water resources and irrigated land current and its contributions to the national economy, challenges and opportunities, and future development perspectives. Ethiopia is noted for having abundant surface and groundwater resources, earning it the nickname "the water tower of East Africa." A large number of lakes, dams, and reservoirs may also be found in Ethiopia's varied regions. Despite significant investment, public engagement, and government strategic support, irrigated agriculture is far from reasonable. Compared to Ethiopia's irrigation potential, the country's current irrigation development is insignificant. As a result, irrigation not play a key role in reducing food insecurity and thereby poverty. When analyzing Ethiopian irrigation, different kinds of literature reflect varying amounts of irrigation water resources as irrigation potentials, current irrigated area, and so on. As a result, there is no systematic and trustworthy inventory of water and irrigation-related potentials in Ethiopia that has been well-studied and documented. Compared to Ethiopia's irrigation potential, the country's current irrigation development is insignificant. Furthermore, even if the present and the potential irrigated area is not well explored. The data and information needed to fully understand the present irrigation schemes are not uniformly available. While data for medium and large schemes can be accurately captured, accounting for small-scale irrigation development, particularly traditional irrigation development and privately developed household-based irrigation schemes that use traditional diversions, water harvesting, and groundwater development is difficult. Different sources report different amounts of irrigation water resources as irrigation potentials, current irrigated area, and so on. This means that Ethiopia's irrigation water resource potential has not been thoroughly researched or documented. As a result, a thorough investigation is required to reach a consensus among researchers. When it comes to irrigation in Ethiopia, different kinds of literature state differing amounts of irrigation water resources as irrigation potentials, as well as the current irrigated area. This means that Ethiopia's irrigation water resource potential has not been thoroughly researched or documented. This requires a thorough investigation that leads to a consensus among researchers. No regular and dependable inventory has been thoroughly researched or documented. Furthermore, even if the existing or potentially irrigated area is not precisely explored
IMPACT OF BANKING PERFORMANCE ON ECONOMIC GROWTH IN SRI LANKA
Get PDFThe objective of this study is to analyze the impact of banking performance on economic growth in Sri Lanka. This study is conducted by using a panel data from 2010 to 2019 for 10 banks to examine the impact of banking performance on economic growth in Sri Lanka. The data was taken from selected banks annual reports. By using panel unit root test, found that at first difference variables are stationary. By using panel co-integration, shows that there is long run and short run co-integration among the variables. A stable banking sector is very important for the economic growth of a country. As policy implications, in order to stabilize economic growth and make the banking sector more resilient, policymakers and bank managers should aim to enhance total assets, return on assets among other things
POLICY EVALUATION AND NATIONAL DEVELOPMENT: SELECTED CASES IN NIGERIA
Get PDFThis paper examined policy evaluation and national development, aimed at understanding how 132/33kv electricity transmission substation at Billiri in Gombe state and 187km Abuja-Kaduna railway construction translated to national development. The research data were both primary and secondary and qualitative analysis. Formal evaluation theory was adopted as a theoretical framework. All social sciences concepts are contextual contested concepts. Concept of policy, evaluation, policy evaluation, development and national development were conceptualisation to guide the reader. The independent variable of the research was policy evaluation while the dependent was national development. There is a symbiotic nexus between the variables. Billiri electricity substation is yet to be completed while Abuja-Kaduna railway was completed later than planned. As a result of this research, we recommended that terms of contract should be observed fully; cost-benefit and sources of funding projects should be considered while making public policy and more so, contracts should be awarded based on merit only
A REVIEW ON STRAWBERRY CULTIVATION IN BANGLADESH: CURRENT STATUS, CHALLENGES AND OPPORTUNITY
Get PDFGathering information on strawberry cultivation, including production, challenges, and opportunities, is critical for developing this sector. This review paper aims to compile information on strawberry cultivation in Bangladesh. Strawberry farming is expanding due to increased demand of the local market, employment opportunities for young farmers, and export potentiality. In Bangladesh, 286 tons of strawberries are produced during 2019-2020. BARI strawberry-1, Rabi 1, Rabi 2, Rabi 3, and Camarosa strawberry are the preferable species cultivated by the farmers. Mainly the young aged people adopt strawberry farming commercially in Bangladesh. The study findings revealed that strawberry farming is difficult as it requires technical knowledge and other challenges such as lack of heat-tolerance variety, less sweetness in strawberries, etc. Planting time is also a significant factor because fruits of early planted plants contained more total soluble solids (TSS) and ascorbic acid than late-planted plants. Though strawberry production increased, still some problems are confronted by the strawberry growers during cultivation and marketing, including lack of quality sapling, dying of plant, lack of capital and technical knowledge, diseases and weed, birds attacks, poor transportation, no specific strawberry market, transportation cost, etc. which are needed to be addressed for further development of this field. Considering countries limited land, lack of appropriate genotype for its commercialization, and unemployed population; strawberries production could be a sustainable option for the developing village economy, nutrition supply, employment opportunities, and export strawberries for earning foreign currency
THE MORPHOMETRIC CHARACTERISTICS AND MERISTIC TRAITS AND CONDITION FACTORS OF Sarotherodon galilaeus FROM THREE MAJOR RESERVOIRS OF EKITI STATE, NIGERIA
Get PDFThe study was carried out between July to October 2018. Seventy-one (71) S. galilaeus(48.6%) from Ado reservoir, Sixty-nine (69) from Egbe- reservoir (47.3%) and six (6) from Ero- reservoir (4.1%) making a total number of one hundred and fourth-six (146) respectively. The fish samples were collected directly from fishermen at the bank of each reservoir. Analysis of variance (ANOVA) was used. The mean body weight and total length of the fish were 179.28± 53.71c and 21.17 ± 2.21c, 102.71 ± 41.78b and 17.75 ± 2.30b and 61.60 ± 2.207a and 15.17 ± 1.37a from Ado, Egbe and Ero respectively. The results recorded on the mean body weights and total lengths of the fish from the three populations are statistically different. But there are morphologically similarities between and among the three populations. Principal component analyses and cluster analyses were further used to determine the closeness of the morphological characters using paleontological statistics (PAST) software. The condition factors (K) values are 0.1 ± 0.04, 0.18 ± 0.04 and 2.5 ± 0.8 from Ado, Egbe and Ero reservoirs respectively. The condition factors value from Ero population was significantly different from the other two populations showed that the two populations (Ado and Egbe) unlike Ero population are not well fed. The robustness of the fish from Ero reservoir may be as a result of enough fertility of the reservoir or that there was a lesser competition from other fish species for the available food resources. There is need to determine the condition factor(s) which favours the growth and development of the fish from Ado (Ureje) and Egbe reservoirs
