International Journal of Pharmaceutical and Phytopharmacological Research , 2013,
Abstract: Quercetin glucosides are transported across intestinal epithelium by active transport. Is not significantly transported by sodiumlinked glucose transporter 1 (SGLT1) and shows lesser intestinal absorption than its glucosides. Quercetin complexes withcyclodextrins have been described to increase its solubility. It has long been assumed that cyclodextrins improve its intestinalabsorption by releasing it near intestinal epithelium and making quercetin available for passive diffusion. In silico molecularmodeling and docking studies provide an accurate and cost effective method to understand these interactions. X-ray crystalstructure of sodium dependent glucose transporter isolated from Vibrio parahaemolyticus was used asa model for dockingstudies. The test ligands including quercetin-γ-cyclodextrin, quercetin-3,4'-glucoside, quercetin-3-glucoside, and quercetin weredocked in predicted active site of Vibrio parahaemolyticus sodium linked glucose transporter (vSGLT). Validation of potentialmean force method used for docking was performed by docking glucose, a natural ligand of vSGLT. It was found that quercetinglucosides and quercetin-γ-cyclodextrin docked analogously with predicted active site of vSGLT and their docking scores werecomparable. Quercetin docked at a different location with less docking score. Theresults point towards possible mimicking ofglucose moieties by γ-cyclodextrin in mechanism of active transport of quercetin and its glycosides by SGLT.

South African Journal of Education , 2003,
Abstract: Optimalisation of the conversion of matriculation symbols for university admission purposes The results demonstrate the potential benefits of taking symbols in individual matriculation subjects into account when predicting university performance. After the internal consistency of the matriculation symbol point totals (MSTs) of three different intakes of first-year students was improved by means of the Elliott-Strenta procedure, this explained a greater percentage (increases of between 0.91% and 3.33%) of the variance of the mean first-year university percentage mark (MPM). For a group of students with the same five matriculation subjects, the incremental gain in criterion variance explained varied between 7.46% and 9.84% when the regression coefficients obtained in a multiple regression were used. Moreover, if the coefficients obtained in this manner were used to weight the matriculation symbol points of subsequent years, the MST-MPM correlations rose similarly. For black students, increases of between 0.94% and 8.48% in explained criterion variance were obtained when the number of standard and lower grade subjects and the number of subjects taken from subject groups D, E and F were also included in a multiple regression equation. The implications of these findings for admissions research, following the introduction of the proposed Further Education and Training Certificate, are pointed out.

PHYSIO-CHEMICAL PROPERTIES OF WATARI IRRIGATION WATER
ADAMU G.K
Academic Research International , 2012,
Abstract: Much of the interpretation of results of water analysis is based on a prediction of the consequences for the soil. Typically, the quality of irrigation water is assessed based on the salt contents and salt inducing parameters, abundance of nutrients, trace elements, alkalinity, acidity, hardness and the amount of suspended solids. The physiochemical properties of the Watari irrigation water were assessed and the Findings indicated that the mean pH of water ranged from 7.10 to 7.50, while the EC values across the sectors ranged from 50 to 60μS/m.Metal cations in the water ranged from 15.00 to 20.07; 5.41 to 16.22; 3.29 to 6.57; 14.83 to 15.00cmol/l for Na, Ca, Mg and K respectively. The SAR ranged from 6.87 to 10.17, while therange of TDS values was from 31.00 to 36.00mg/l. The mean carbonates concentration detected in the irrigation water was from 4.00 to 12.00cmol/l, while the mean bicarbonate content ranged from 22.00 to 55.00cmol/l. Chloride and nitrate were within 9.87 to 31.58 and1.00 to 1.65mg/kg, respectively. The residual sodium carbonate (RSC) ranged from 8.00 to 30.69.There was no detectable NH4 in the irrigation water. It was recommended that adequate drainage with emphasis on surface drainage should be provided to reduce the risk of salinity whereas salt and sodium build up should be monitored regularly.

Ground Water Quality Assessment in the Basement Complex Areas of Kano State Nigeria
Adamu G.K
American Journal of Engineering Research , 2013,
Abstract: The research aimed at assessing the quality of underground water for safe drinking in the basement complex region of Kano state. In achieving this aim a total of twenty (20) boreholes were selected at random across the state. Thirteen (13) relevant parameters on the test of water quality were taken into consideration. The research found out that underground water in the area is safe for drinking due natural filtration process that the water undergo, because, the soil chemistry and mineralogy alters the chemistry of the water there by making it safe for drinking by meeting the standard requirement of World Health Organisation (WHO) 1984. It is therefore recommended that, more boreholes should be constructed through the intervention of both government and other relevant organsations. Also surface water source should also be improve to reduce the burden that underground water source might have encountered.

American Journal of Engineering Research , 2013,
Abstract: This research was carried out in Watari River Irrigation Project, located on the slopes of Watari River valley in Bagwai local government of Kano state with aim of assessing soil properties and quality of irrigation water. A total of 32 representative soil samples were randomly collected from the eight sectors. Seven water samples were also collected from the sectors and the dam. The samples were treated and analyzed for physical, chemical and fertility related indices. Typically, the quality of irrigation water is assessed based on the salt and salt inducing contents, the presence and abundance of micro and macro nutrients, trace elements, alkalinity, acidity, hardness and the amount of suspended solids. The results are grouped into general quality parameters which included salinity and salt inducing cations and anions and pollutants. The Findings indicated that the mean pH ranged from 7.10 to 7.50, while the mean EC values across the sectors ranged from 50 to 60μS/m. The mean metal cations in the water ranged from 15.00 to 20.07; 5.41 to 16.22; 3.29 to 6.57; 14.83 to 15.00cmol/l for Na, Ca, Mg and K respectively. The SAR ranged from 6.87 to 10.17, while the range of TDS values was from 31.00 to 36.00mg/l. The mean carbonates concentration detected in the irrigation water was from 4.00 to 12.00cmol/l, while the mean bicarbonate content ranged from 22.00 to 55.00cmol/l. The ranges for chloride and nitrate were 9.87 to 31.58 and 1.00 to 1.65mg/kg respectively. The residual sodium carbonate (RSC) ranged from 8.00 to 30.69.There was no detectable NH4 in the irrigation water. The results have shown that all the eight sectors had sand dominated texture. The mean pH in the soil ranged from 5.50 to 5.95. The EC ranged between 0.49 to 1.30cmol/kg, the Clranged between 0.29 to 1.07cmol/kg and SAR ranged between 0.13to 0.72. The mean soil organic carbon across the sectors ranged between 0.62 to 1.49%. The total nitrogen ranged between 0.0043 to 0.084% while NH4+and NO3-Forms of nitrogen ranged between 0.0043 to 0.0065cmol/kg and 0.0025 to 0.0065mg/kg respectively. The CEC ranged between 9.04 to 12.68cmol/kg. The exchangeable bases ranged from 3.13 to 4.25; 1.06to1.73 and 1.28 to 2.08cmol/kg for Ca, Mg and K respectively. The boron content in the soil across the sectors ranged between 4.09 to 6.34mg/kg. It was recommended that adequate drainage with emphasis on surface drainage should be provided and salt and sodium build up should be monitored regularly.
USE of Faidherbia albida for Soil Improvement in Small Holder Farming System of Gezawa Local Government Area of Kano State, Nigeria

Research Journal of Environmental and Earth Sciences , 2012,
Abstract: Soil fertility depletion has been described as one of the major biophysical root cause of declining per capita food production. The study was carried out to investigate the use of Faidherbia albida as soil quality improvement practice in small holder farming system of Gezawa local government of Kano state. The population of F. Albida trees in the four villages selected for the study was obtained through questionnaire survey; this is to assess the potentials and current uses of the tree in both forestry and agricultural systems in the area. For soil quality assessment, 10 composite soil samples collected at the depth of 0-20 cm were analyzed for physical, chemical and fertility related indices. The analytical result revealed an increase in all the parameters tested except sand which decreased when compared to earlier work in the area. The questionnaire interviews involved farmers and foresters and the results showed that there was significant decrease in the population of the tree over the years. It was also found that the tree had been regarded as an important agro forestry species and helps in the improvement of soil fertility and subsequently crop yield, reduction of heat stress and the provision of fodder for livestock feeding.
Collaborative Web-based Development of an Electronic Meeting Agenda using Secretarius Moderation
G.K. Raikundalia
Research Journal of Information Technology , 2011,
Abstract: Traditional, formal, face-to-face meetings are heavily reliant on documents for their conduct. One of the most prominent and important documents is the agenda. The agenda is vital for structuring and driving meeting discussion. The development of the agenda relies on contributions of items for discussion from meeting participants before the meeting. The secretary considers these items for their relevance and potential to achieve the meeting goal. A formal, electronic meeting, being a computer-supported equivalent of a traditional meeting, is also dependent on a useful and effective agenda for its success. This research article presents Logan, a Web Electronic Meeting Document Manager (WEMDM), that provides a novel, hypermedia-based technique for supporting the above agenda development process. Logan allows asynchronous, collaborative development of a meeting agenda. High participant involvement is supported through item contribution and secretarius moderation of contributions. Through a contribution rejection system, moderation supports selection of appropriate contributions for the agenda. Participants are helped in contributing relevant agenda items or prevented from contributing one similar to those in the current agenda via rejected contributions. The process allows flexibility in agenda development as the process may involve one or more iterations. The agenda development process is covered by displaying the interworking of participant agenda development pages. The many Web user interfaces used by the secretarius and other participants in agenda development are shown and described.

The role of the World Organisation for Animal Health (OIE) to facilitate the international trade in animals and animal products : policy and trade issues
G.K. Bruckner
Onderstepoort Journal of Veterinary Research , 2010, DOI: 10.4102/ojvr.v76i1.78
Abstract: The international trade in animals and animal products has become a sensitive issue for both developed and developing countries by posing an important risk for the international spread of animal and human pathogens whilst at the same time being an essential activity to ensure world-wide food security and food safety. The OIE has since its founding in 1924, applied a democratic and transparent decision-making process to continuously develop and review international standards for animal health and zoonoses to facilitate trade in animals and animal products. The role of the OIE is also mandated by the World Trade Organization (WTO) as international reference point for standards related to animal health. In support of its overall objective of promoting animal health world-wide, the OIE has also launched several other initiatives such as the improvement of the governance of veterinary services within its member countries and territories and to enhance the availability of diagnostic and scientific expertise on a more even global geographical distribution. Several trade facilitating concepts such as country, zonal and compartment freedom from disease as well the trade in disease free commodities has been introduced to enhance the trade in animals and animal products for all its members including those from developing and transitional countries who are still in the process of enhancing to full compliance with international sanitary standards.
