Contribution towards the knowledge of Rhinotragini (Coleoptera, Cerambycidae). V. Reconsideration of Rhopalessa rubroscutellaris (Tippmann, 1960)
Clarke, Robin O.S.;Martins, Ubirajara R.;Santos-Silva, Antonio;
Papéis Avulsos de Zoologia (S?o Paulo) , 2012, DOI: 10.1590/S0031-10492012002200001
Abstract: corrections to the revision of rhopalessa bates, 1873 (clarke et al. 2011), with the transfer of two species to a new genus, rashelapso: r. durantoni (pe?aherrera-leiva & tavakilian, 2004) comb. nov., and r. schmidi sp. nov. (previously considered to be conspecific with ommata (rhopalessa) rubroscutellaris tippmann, 1960 by the authors). ommata (rhopalessa) rubroscutellaris is now considered a junior synonym of laedorcari fulvicollis (lacordaire, 1868).

Abstract: the genus rhopalessa is revised and divided into two groups: the clavicornis-group with r. clavicornis (bates, 1873), r. demissa (melzer, 1934), r. hirticollis (zajciw, 1958), r. moraguesi (tavakilian & pe?aherrera-leiva, 2003), r. pilosicollis (zajciw, 1966) and r. subandina sp. nov.; and the rubroscutellaris-group with r. durantoni (pe?aherrera-leiva & tavakilian, 2004) and r. rubroscutellaris (tippmann, 1960). two species were synonymyzed with r. clavicornis: ommata (rhopalessa) nigrotarsis fisher, 1937 and ommata (rhopalessa) nigricollis zajciw, 1969.

Effectiveness of Base Plate Thickness Design Criteria in Steel Columns
O.S. Abejide
Research Journal of Applied Sciences , 2012,
Abstract: Steel column base plates are one of the most fundamental parts of a steel structure, yet the design of base plates is commonly not given the attention that it should. This result in base plate details that are expensive, difficult to fabricate and may even contribute to the hazards of the steel erection process by not providing stability for erection load applied to the column(s). The effective area method recommended in BS5950 has been used to study the effectiveness of base plate thickness under various loading conditions with due comparison to AISC provisions. Results indicate that although it is a semi-empirical method, it is more reliable than the empirical method recommended in BS5950; also the approach offers more economy and can be used for all column sections.
Reduction of the High Technical Power Losses Associated with the Nigerian 330KV Transmission Network
O.S. Onohaebi
International Journal of Electrical and Power Engineering , 2012,
Abstract: This study carried out an in-depth study and analysis of power losses associated with the Nigerian 330 kV and proposed modifications to the existing network to improve the efficiency, reliability, security and ensure good quality power for the citizenry. The research methodology involved the power flow analysis of the existing network and subjecting it to contingency analysis and simulation using Newton-Raphson method in Power World Simulator (PWS) environment. The study revealed that the existing network cannot cope with contingencies leading to very low performance and even blackout at emergencies. The proposed modifications to the 330 kV transmission network which incorporated some additional lines to form more loops and minimal compensation, meet the acceptable voltage limits of 5%. It also reduces the energy losses from 337.5-189.9 MWH, representing 45% improvement over existing network and enhances reliability and security of the transmission grid.
Evaluation of Energy and Micronutrients Intake of Nigerian Adolescent Females: A Case Study of Institutionalized Secondary Schools in Akure South Local Government Area, Ondo State, Nigeria
Ijarotimi O.S.
Pakistan Journal of Nutrition , 2004,
Abstract: The objective of the study is to provide information on the energy and micronutrients intake of Nigerian adolescent females. A cross-sectional surrey was conducted among the 323 institutionalized adolescent females of 10-19 years age range in Akure South LGA, Ondo State. The energy and micronutrient intake were determined by weighing the food intake of the subjects and part of the food samples were subjected to chemical analysis The mean mineral intakes were: Ca 567 mg/kg, Mg 261 mg/kg, Zn 7.58mg/kg, Fe 19.8 mg/kg and P 136.8 mg/kg. And the vitamins intakes were vit. A 860 mg/kg, Thiamine 0.7 mg/kg, Riboflavin 0.28 mg/kg, Niacin 3.27 mg/kg, vit. C 9.1 mg/kg, Vit. D 2.14 mcg/kg Folic acid 9.8 mcg/kg and Vit. B12 1.2 mcg/kg, and the energy intakes was 6.45 MJ. The result showed that high proportion of the subjects were not meeting the RDA for energy and some of the micronutrients intake.
