The Na.iona. Nuclea. Resea.ch Institute of the Gha.a.a.omic Energy Commission is underta.ing steps to convert the Gha.a.Resea.ch Rea.tor-1 from HEU Core to LEU. The proposed LEU core consists of 12.5% enriched UO2 fuel elements cla. in Zirca.oy-4 a.loy. This is done in colla.ora.ion with Reduced Enrichment for Resea.ch a.d Test Rea.tor. The versa.ile MCNP code wa. used to a.a.yse the neutronics pa.a.eters given in the Sa. of HEU core, thereby cha.a.terizing the core. Subsequently, the LEU core wa. indentified with necessa.y cha.ges to the HEU MCNP model. It wa. a.certa.ned tha. the rea.tivity for the LEU core with the sa.e number of fuel pins a. the HEU wa. ina.equa.e, hence the fuel pins were increa.ed from 344 to 348. The neutron flux a. the irra.ia.ion sites wa. found to be below the nomina. va.ue a. full power for the LEU a.d hence the nomina. power wa. increa.ed to 34 kW for a.nomina. flux va.ue of 1 × 1012 n/cm2.s. The pa.a.eters investiga.ed for the HEU a.d LEU a.e shown in this pa.er.

文章提出了一种对直觉本质的解释,该解释或可为哲学和心理学的直觉研究提供一个统一框架。首先,文章基于理智表象的一个原型,展示了对近期有关哲学文献的整合,而这原型来源于一种常见的悖论——从而表明,对于理智表象的概念而言,其与知觉的类比不是必要的。在解释了直觉表象所具有的一般的自发性后,文章结论部分展示了前文所辩护的理论不仅整合了此前哲学和心理学中关于直觉的研究,而且还可能使这两个学科未来的直觉研究更为体系化。

Ba.kground: In recent times, there ha. been a. increa.e in the number of La.sa.fever ca.es resulting from the severa. episodes of La.sa.fever epidemics ra.a.ing Nigeria.a.d other West a.rica. countries. The presence of La.sa.virus in rodents other tha. the ma.or reservoir (Ma.tomys na.a.ensis) ha. been a.public hea.th concern a. to the a.tua. burden of the disea.e. It is therefore of a.public hea.th necessity to explore the La.V RNa.ha.ouring potentia. of severa. species of rodents in endemic a. well a. non-endemic a.ea. for proper prevention of emergence of outbrea.s in non-endemic a.ea.. Objectives: The a.m of this study wa. to detect the presence of La.V RNa.in different species of rodents in Ikorodu, La.os sta.e a.d a.eokuta. Ogun sta.e. Methods: a.tota. of ninety one (91) rodents were ca.tured from Ikorodu, La.os Sta.e (61 rodents) a.d a.eokuta. Ogun Sta.e (30 rodents), eutha.ized, bled, a.d pla.ma.obta.ned for the detection of La.V RNa.by Reverse Tra.scripta.e Polymera.e Cha.n Rea.tion. Results: a.tota. of 91 rodents consisting of 77 Ra.tus ra.tus a.d 14 Crocidura.spp. The S segment of La.V RNa.wa. not in a.y of the 91 rodents’ pla.ma.sa.ples. Conclusion: The rodents ca.tured within the rura. communities of Ikorodu, La.os Sta.e a.d a.eokuta. Ogun Sta.e were found not to ha.our the La.V RNa. This study is limited by the rela.ively sma.l sa.ple size. Simila. studies should be encoura.ed both in endemic a.d non-endemic a.ea. in order to understa.d the a.tua. burden of La.sa.fever a. well a. put into check future epidemics.
