COVID-19是一种全球性流行病,已导致贸易和发展活动下降,导致一些国家陷入衰退,全球年增长放缓。发达国家通过增加支出和使用货币政策来应对COVID-19大流行,但较贫穷的国家在财政和货币应对方面的选择有限。该研究旨在调查COVID-19大流行对尼日利亚商业活动、贸易、投资、经商成本和经济发展的影响程度。这项研究结合了关于COVID-19、交易活动、人们的储蓄和投资、经商成本和经济发展以及调查设计的多篇文献的见解。假设检验结果表明,贸易活动、人们的储蓄和投资对经济发展具有正向意义,而疫情对贸易和经济发展的影响不显着。这项研究表明,COVID-19对各国经济发展产生了影响,因此需要监管和改革政策以改善贸易活动和经济绩效。国家当局和多边实体应考虑采取前所未有的政策措施来应对这一流行病,例如削减利率、注入流动性以及为公司、企业和家庭提供紧急资金。直接工资或收入支持措施有助于限制不可预见情况的社会经济影响,例如延期纳税、政府补贴的短期工作计划、暂停支付抵押贷款和直接现金支付。社会保护计划需要惠及最需要帮助的人,双边贸易协定必须解决供需问题,以防止短缺、价格飙升和苦难。

adsorptive Treatment of Textile Wastewater Using Activated Carbon Produced from Mucuna pruriens Seed Shells

Mucuna pruriens seed shells (abundantly available agricultural waste) were processed, treated and activated using 60% orthophosphoric acid for removal of congo red and malachite green from an aqueous solution. Its physicochemical properties and its removal efficiencies on the textile dyes were determined. The effect of particle size, adsorbent dose, initial pH of solution, adsorbate concentration and contact time on the process of adsorption was investigated. The equilibrium, kinetic and thermodynamic properties of the dyes removal were also investigated. The experi-mental data were modeled using linear regression method of analysis. The correlation coefficient was used as a criterion for model adequacy and acceptance. Sum of squares error was used to val-idate the isotherm models. The pseudo second-order kinetic model was found to best correlate the experimental data. The intraparticle diffusion is not the only rate controlling step in the process. The experimental data were found to follow the Langmuir, Freundlich and Tempkin isotherm models. The negative free energy indicated that the adsorption processes were spontaneously feasible. The process of adsorption has been found to be endothermic in nature. The removal of malachite green was found to be more spontaneous and feasible than the removal of congo red on the adsorbent. From the study it was deduced that the Mucuna pruriens seed shells activated with phosphoric acid were found to be a good adsorbent for the treatment of textile wastewater con-taining congo red and malachite green.

Full term secondary abdominal pregnancy in a Jehovah’s witness: A case report

Case Reports in Clinical Medicine 2012年第2期1卷 19-22页

We describe a rare case of full term abdominal pregnancy in a Jehovah’s witness patient;she underwent laparotomy successfully without blood transfusion. Despite their belief regarding transfusion, Jehovah’s witnesses may not necessarily have a higher morbidity or mortality rate following a complex obstetric surgery as seen in the present case.

Does the Breast Size in Females Correlate with the Severity of Mechanical Low Back Pain?

引用

Journal of Biosciences and Medicines 2021年第4期9卷 116-121页

作者： Emmanuel C. Iyidobi Osita Ede chinenye C. obi Violet O. Onwuekwe Cajethan U. Nwadinigwe Theclar O. Iyidobi Oke R. Obadaseraya Department of Orthopaedics and Trauma National Orthopaedic Hospital Enugu Nigeria Department of Psychological Medicine University of Nigeria Teaching Hospital Enugu Nigeria

Background: Large breast is postulated to cause undue tension in the paraspinal muscles and may result in back pain. Improved pain score following mammaplasty supports this assertion. Such a question has not been evaluated in an indigenous black population. Objectives: To assess the correlation between the breast cup size and the severity of low back pain among women with mechanical low back pain. Method: This was a prospective cohort study. Eighty-four women with chronic backpain attending the Orthopaedic clinic participated excluding psychogenic back pain. The breast cup sizes were estimated from the difference between the bust and band sizes measured with an inelastic tape. The severity of pain was determined with the Oswestry disability index (ODI) data analysed with IBM SPSS version 26. Results: The mean age was 49.35 years. The predominant breast cup size was A, (88%), while the largest cup size was C. The mean duration of symptoms and ODI score was 3.33 months (SD = 2.63), and 42.30 (SD = 16.98) respectively. The breast cup size did not show a positive correlation with ODI score, r = ?0.021, p = 0.846. Conclusion: The severity of mechanical low back pain does not correlate with the breast cup size.
