Cataloging and Classification Skills of Library and Information Science Practitioners in their Workplaces: A Case Analysis
Get PDFInformation resources are useless when access is not provided. This fundamental function is within the concept of cataloging. Thus, cataloging is an essential process that provides access to all acquired information resources of the library for it allows people to find information needed for their personal and professional growth and development. It also provides access points to information resources in a way that users will be able to find the need information or resources.
With this, the study determined the cataloging and classification skills of library and information science graduates which is centered on assessing the cataloging and classification skills of academic and school librarians in three areas namely, descriptive cataloging, subject analysis and classification. Case analysis was used to five practicing librarians who graduated with the degree Bachelor of Secondary Education major in Library Science and Bachelor of Library and Information Science from the College of Teacher Education, Benguet State University (BSU).
Findings of the study revealed that the cataloging and classification skills of the five library and information science graduates of BSU are generally proficient in the basic areas of descriptive cataloging, subject analysis and classification but found greatest difficulty on subject.

Climate Change and Coping Strategies among Peasant Farmers in Akwa Ibom State, Nigeria
Get PDFThe study investigated peasant farmer’s adaptation strategies to climate change in Akwa Ibom State. A multi-stage random sampling was used to select 120 respondents for the study. Interview schedule was used to collect data from the 120 farmers randomly selected. The study revealed that 40% of the respondents were within the age range of 31 to 40 years. Thirty seven percent (37%) of the respondents had formal education while 47% of the respondents had I to 3 persons in their respective households. Years of experience in farming of most respondents were between 1 and 10 years. The result further revealed that about 79% of the respondents had 0.6 – 1.0 hectare of form while 68% of the respondents had contact with extension agents/officers once a month. The result showed that all the explanatory variables included in the model were significant determinants of adaptation measures to climatic condition. It was therefore recommended that the state government should encourage increased frequency of extension contact to significantly increased farmers’ awareness to changing climatic conditions as well as adaptation strategies
Enhancement of Bilirubin Excretion in Alloxan - Induced Diabetic Rats Treated with Crude Aloe vera Gel
Get PDFThis study was aimed at determining the effect of type 1 diabetes mellitus on bilirubin excretion, and to ascertain the impact of treatment with crude Aloe vera gel on bilirubin excretion. The phyto-constituents and median lethal dose of the plant material were determined before administration. Forty albino wistar rats were randomly assigned into four groups of 10 rats each as follows; control group, alloxan - induced diabetic untreated group (DM), alloxan - induced diabetic treated group (DMT) and control treated group (CT). The dose of crude Aloe vera gel used for this study was 0.2ml/100g body weight daily, per oral route. Biliary total bilirubin (BTB) and serum total bilirubin (STB) concentrations were significantly (p<0.001) increased in the DM group compared to control, DMT and CT group. BTB and STB concentrations were significantly lower (p<0.001) in DMT group compared to DM group. BTB and STB concentrations were significantly reduced in the CT group compared to control. Biliary conjugated bilirubin (BCB) and serum conjugated bilirubin (SCB) concentrations were significantly lower (p<0.001) in the DM, DMT and CT group compared to control. BCB and SCB concentrations were significantly lower (p<0.001) in the DMT group compared to DM group. BCB and SCB concentrations were significantly lower (p<0.001) in the CT group compared to control. Biliary unconjugated bilirubin (BUB) and serum unconjugated bilirubin (SUB) concentrations were significantly increased (p<0.001) in the DM group compared to control, DMT and CT group. BUB and SUB concentrations were significantly reduced (p<0.001) in CT group compared to control. These results are suggestive of the fact that crude Aloe vera gel enhances excretion of bilirubin in diabetic and normal conditions.

Productivity improvement in Breweries through line balancing using Heuristic method
Get PDFThis paper presents a heuristic procedure for improving productivity in breweries companies. A case study of Champion brewery Plc, Uyo, Akwa Ibom State was adopted. The aim of this paper is to balance the Production line of Champion lager beer. In the course of line balancing, the idle time and the number of workstations on the production line was minimized so as to maximize the efficiency of the production line. All the required data was measured and the parameters such as elapsed time at each work station, efficiencies, number of workers, time of each of the workstations etc. was calculated from the existing line. A new heuristic approach, the Longest Operation Time (LOT) method was used in designing the new production line. After set up of the new production line, the cost of production and effectiveness of the new line was computed and compared with those of the existing one. The new production line was found to have been increased by a significant amount reducing the overall production cost per unit.

Evaluation of complementary use of organic manure for sustainable water yam production in Uyo, southeastern Nigeria
Get PDFA two year study was conducted at University of Uyo Teaching and Research Farm, Use Offot, Uyo, Akwa Ibom State in 2009 and 2010 cropping seasons to assess the effects of complementary use of different organic manures on water yam growth and yield, economic returns to management as well as attack by some pests . The experiment was laid out in a randomized complete block design with three replicates. There were 8 fertilizer treatments viz: poultry manure (PM), goat manure (GM), and oil palm bunch ash (OPBA) each at 20 tha-1 , OPBA + PM, OPBA + GM and PM + GM each at a ratio of 1:1 (10 tha-1 + 10 tha-1), NPK (15:15:15) at 400 kgha-1 ( a recommended dose of inorganic fertilizer) and control (no soil amendment). Results showed significant differences on vegetative traits, number of days to senescence and yield and yield components of water yam. Treatments that received complementary application of PM + GM produced the highest tuber yield (26.15 and 27.96 tha-1 in 2009 and 2010, respectively with corresponding cost- benefit ratios of 14.17 and 15.49,respectively) followed by complementary use of OPBA + PM, (24.22 and 27.03 tha-1,respectively). The use of inorganic fertilizer (NPK - 15:15:15) produced 22.60 and 23.81 tha-1 of yam tuber with a corresponding cost -benefit ratio of 11.02 and 10.88 in 2009 and 2010, respectively .All organic manure based treatments had no symptom of termite and yam beetle attack. This study indicates strongly the potentials of complementary use of organic manures for sustainable water yam production in Uyo, southeastern Nigeria.

Thermal State of the Niger Delta Basin
Get PDFThe Thermal State of the Niger Delta Basin is presented. Subsurface temperatures obtained from continuous temperature logs in 260 wells allowed to stabilize for several months were used in determining the Geothermal Gradients in the Niger Delta. Regional gradients are lowest (0.82oC/100m) at the central part of the Delta and increases both seaward
and northward up to 2.62oC/100m and 2.95oC/100m respectively in the continental sands of the Benin Formation. In the Marine paralic deposition,
Geothermal Gradients range from 1.83oC/100m to 3.0oC/100m at the central portions. The highest values of 3.5oC/100m to 4.6oC/100m are seen northward while intermediate values of 2.0oC/100m to 2.5oC/100m are recorded seaward. The thermal gradients are clearly influenced by the lithology or rate of sedimentation in the area. Regions of low thermal gradient correspond with areas of high sand percentage, primarily because sands are better conductors than shale and therefore show as low thermal gradient. The thermal conductivity for sand and shale, the predominant lithology in the Niger Delta show a wide variation from well to well. In the Benin Formation, conductivity ranges from 5 2 W/mK to 10 4 W/mK with an average value of 8 W/mK. The lowest values are found offshore westward, while highest values are northward. The central portion has between 6 – 10W/mK. The
conductivity values however decreases when one approaches the Marine paralic section with an average value of 6 W/mK. A significant regional trend of relatively low heat flow at the central part (20 – 30 mW/m2) increases both seaward and northward (40 - 55 mW/m2) is observed in the area.
The lowest heat flow is obtained in the central part of the Delta. The highest heat flow is in the northern part, with values exceeding 50 mW/m2. The present study has shown that temperature can be predicted as a continuous profile unlike the Bottom Hole temperature, which gives values for two or three data points in a borehole. The knowledge of thermal properties has direct relevance for hydrocarbon exploration
Cointegration between Exchange Rate Volatility and Key Macroeconomic Fundamentals: Evidence from Nigeria
Get PDFThe study modelled the short run and long run impact of some macroeconomic fundamentals on the exchange rate volatility in Nigeria. Unit root test conducted on the specified time series showed that all series were integrated of order one. The short-run and long-run elasticities of exchange rate volatility with respect to some key macro-economic fundamentals were determined using the techniques of co-integration and error correction model estimation. The empirical results revealed that the coefficients of the total import, industrial capacity utilization rate, lending rate of commercial Banks, foreign private investment and liberalization policy period are significant in the long run. Whereas the coefficients of external reserves, inflation rate, interest rate, foreign private investment, total import and industrial capacity utilization rate were significant in the short run. The result advocated for appropriate short and long term policy packages that should focused on stabilization of the identified significant shifters of exchange rate volatility in the Nigeria’s economy. Harmonization of transactions in the various foreign exchange markets in Nigeria should be a priority objective in the current exchange rate policy.

Evaluation of Yield Productivity and Economic Returns of Some Yam (Dioscorea esculenta Poir) Genotypes Grown in a Kaolinitc Ultisol
Get PDFA two-year (2008 and 2009) study was carried out at the University of Uyo Teaching and Research Farm, Use-Offot to evaluate yield productivity of eight yam genotypes (TDr 200/3/7A, M2/75/3, M2/25/1, M2/50/5x, 99/AMO/053, 99/AMO/094, 95/18894, and local -Eteme).and their economic returns to management. Randomized Complete Block Design with three replicates was used. Results of the study indicated significant differences in all the yield and yield components of the different yam genotypes considered in both years., Cost of production in 2009 was 2% above the cost of production in 2008 due to increase in cost of land preparation. The cost -benefit ratio of all the genotypes were above 10.00 except in local variety, Eteme with values of 4.9 and 6.3 in 2008 and 2009,
respectively. The average cost- benefit ratio of 14.25 recorded in TDr 95/18894 suggesting strongly that the genotype is more adaptable to Uyo, agro- ecology than others
Modeling the Dynamic Relationship between Food Crop Output Volatility and Its Determinants in Nigeria
Get PDFThe study modeled the short run and long run food crop output volatility equations in Nigeria. Time series data derived from the FAO data base for Nigeria and publications of the CBN covering the period 1961 to 2010 was used in the study. Unit root test conducted on the specified time series shows that all series were integrated of order one at 1% probability level. The GARCH (1, 1) model was used to generate the food crop output volatility for the selected food crops (i.e. rice, maize, sorghum, cassava and yam). The short-run and long-run elastic cities of food crop output volatility with respect to specify explanatory variables were determined using the techniques of co-integration and error correction model estimation based on the OLS estimation. The empirical results revealed that inflation rate, per capita real GDP, loan guaranteed by ACGSF in the food crop sub sector, harvested area of land for food crop and liberalization policy era had mixed influence on food crop output volatility both in the short and long run periods in Nigeria. The result also showed that harvested area of land for the selected food crop was the most important factor that affects food crop volatility in the country. In addition, food crop volatility show an average declines pattern in the liberalization policy period. The study however advocated for appropriate short and long term policy packages that should addressed appropriately the identified significant macroeconomic shifters of food crop output volatility in the country. Also attention should be directed towards improving the quality of land allocated to food crop sub sector. Furthermore, agricultural policies in the liberalization policy package should be design in the short term basis and use as a means for altering food crop output in Nigeria.
