Budget Discipline in Government: A Key to Building and Sustaining Buoyant External Reserves
O.F. Olaoye
The Social Sciences , 2013, DOI: 10.3923/sscience.2010.386.390
Abstract: Government budgeting among other objectives suppose to be a guide to government spending as a tool of financial resource allocation for a particular time referred as the budget period. Consistent adherence to approved estimates over a period of time depicts the seriousness a government and its official attach to the polices itemize in the policy document called budget. This will engender growth and development within an economy. In developing economies as Nigeria, supplementary budgets, budget-deficits and budget abuse are common occurrences. The study therefore, examines what government budget objectives should be the practice of budget discipline, the connection between government budget and external reserve and why budget indiscipline is becoming a culture in Nigeria. The study concludes by putting in place useful suggestions on how to safeguard the fledging buoyant external reserves of Nigeria.
Line x Tester Analysis for Resistance to Cassava Anthracnose Disease
O.F. Owolade
World Journal of Agricultural Sciences , 2006,
Abstract: Thirteen cassava (Manihot esculenta) varieties which includes four IITA Improved used as lines and seven Landraces used as testers with various level of resistance to Colletotrichum gloeosporioides f. sp. manihotis, were crossed in a Line X tester design to determine the general (GCA) and specific (SCA) combining abilities relative to the inheritance. The Parents and the 36 F1 hybrids were evaluated in year 2003 and 2004 on an infected field. The variances due to SCA and GCA showed that both additive and non-additive, possibly epistatic gene actions are important. Majority of the crosses between the resistance sources and the susceptible lines showed intermediate reactions and various degrees of partial dominance for canker development in cassava plants. The most resistance IITA improved variety I63397, had the highest negative GCA effect for resistance among the lines. The moderately resistance TME-8 had largest significant negative GCA among the landraces. Most the crosses involving I63397 and TME-8 had significantly high negative SCA effects. The contribution of these parents to heterosis of their hybrids will be towards reduction of disease symptoms. This suggests the importance of both the additive and non-additive in the development of resistance to cassava anthracnose disease. Therefore recurrent selection with progeny evaluation is advocated for breeding for resistance to the disease.
Some aspects of оesophagus morphogenesis at the early stages of prenatal ontogenesis in human being
Marchuk O.F.
Морфолог?я , 2008,
Abstract: The peculiarities of esophagus morphogenesis and topography formation in embryos and prefetuses of human being by the complex of morphological methods hаve been studied. Topographical differences in germ of esophagus and respiratory tube was set. In embryos of 4.5-5.0 mm PCL the process of diaphragm formation was observed, which was complete in prefetuses of 18.0-19.0 mm PCL. In embryos of 9.0-9.5 mm PCL the enlarge of circular layer of esophagus muscular membrane was observed; in embryos of 18.0-19.0 mm PCL the longitudinal layer was enlarged. In further development a circular layer thickness was in prevalence due to the thickness of longitudinal layer along all length of esophagus. As a result of condensing interorganic layers of mesenchyma more close correlative intercommunications between esophagus, trachea, thoracic aorta, vagus nerves and serous membranes was set. At the end of prefetuses period the process of recanalisation of esophagus was completed.
Suitability of Some Local Bast Fibre Plants in Pulp and Paper Making
O.F. Olotuah
Journal of Biological Sciences , 2006,
Abstract: Morphological and Anatomical analyses were carried out on eight bast fibre plants from two families; Malvaceae and Fabaceae in Akungba-Akoko. In the anatomical study, the fibres were extracted and a total of fifty cells were measured for each species. Certain fibre properties, the cell lumen, diameter and cell wall thickness were determined from which the Runkel ratio, slenderness ratio and flexibility ratio were obtained to consider the suitability of the plants in pulp and paper making. The studies on fibre properties showed that the fibre lengths ranged between 2.20 mm for Hibiscus sabdariffa and 3.92 mm for Sida acuta with variations within the measured lengths of a species. The best fibre distributions were observed in Hibiscus cannabinus with 78% and Urena lobata 80%, having lengths of more than 2.5 mm and a Runkel ratio of less than one.
Induction of Genetic Variation in Cowpea (Vigna unguiculata L. Walp.) by Gamma Irradiation
O.F. Adekola,F. Oluleye
Asian Journal of Plant Sciences , 2007,
Abstract: Cowpea IT84S2246D mutants were screened for useful agronomic traits. Dry seeds of cowpea ’IT 84S2246D were exposed to gamma irradiation from cobalt 60 source at 196 and 245 Gy dosages. The non-irradiated parent was used as the control. Identification and selections were carried out at the second generation (M2). The eight mutants selected from 245 Gy population included plants with light green pods, plants with leaflets having tendrils, early maturing plants with broad leaflets, plants with pigmented pods and plants with pods above canopy. They also included plants with dark green pods, plants with wide angled pods and pigmented plants with hairy pods. The two mutants selected from 196 Gy populations were early maturing and dwarf plants. The selected mutants were found to possess useful agronomic traits capable of conferring on them selection advantage for increased yield, easy harvesting and insect tolerance.

Comparison of the Mineral Content and Apparent Biological Value of Milk from Human, Cow and Goat
M. A. Belewu, O.F. Aiyegbusi
Journal of Food Technology in Africa , 2002,
Abstract: The mineral content and apparent biological value (ABV) of milk from Human (T1), White Fulani (Bunaji) cow (T2) and West African dwarf goats (T3) (n=10) were assessed following a completely randomised design model and covariance analysis respectively. Concentration per million (ppm) were 210, 150 and 52 Na, (goat, human and cow milk) while potassium content was similar (P>0.05) in human (1.60) and goat (1.55) milk compared to that of cow milk. Quantity of Ca, Mg, P, Fe, Cu and Mn were higher in goat and human milk. They were lowest in cow milk: 4.03, 0.92, 1.07, 0.25 and 1.59ppm respectively. In these three treatments, the respective ratios Ca.P-1 were 4.2:1 (T1), 4.4:1 (T2) and 4.6:1 (T3) while Ca.Mg-1 and P.Mg-1 were decreased from 3.9 (cow milk) to 1.9 (human milk) and 0.89 (cow milk) to 0.45 (human milk). In conclusion, the milk of goat (West African dwarf) which contained more of these mineral contents similar to that of human milk, is a pointer to the nutritional contribution of goat milk in a country like Nigeria where prevailing undernourishment and malnutrition are accompanied by low intake of some minerals and vitamins among the populace and most especially the vulnerable (pregnant, lactating mothers, infants and weanlings and the sick) groups. The Journal of Food Technology in Africa Volume 7 No.1, 2002, pp. 9-11 KEY WORDS: West African dwarf goat, White Fulani (Bunaji) cow, Mineral composition, Apparent Biological Value.

Floral Biology and Pollination Ecology of Cowpea (Vigna Unguiculata L. Walp)
Ige, O. E.,Olotuah, O.F,Akerele, V.
Modern Applied Science , 2011, DOI: 10.5539/mas.v5n4p74
Abstract: Studies on the floral biology and pollination ecology of three varieties of cowpea (Vigna unguiculata L. Walp) were carried out. The varieties studied were Var. Oloyin, Var. Sokoto, and Var. Drum. Cowpea is a self pollinated crop which is encouraged by the arrangements of the floral parts. However, Insects visiting cowpea flowers have been implicated in the movement of pollen from one cowpea plant to another. Flower opening of cowpea begins between 6:00am and 6:30am and closes between 11:30am and 12:00pm. Pollen analysis showed similarities in the pollen morphology of the cowpea varieties. Moreover Var. Drum produced the highest number of pollen grains per flower in terms of pollen productivity.
