The objective of this paper is to investigate the therm.dynam.c properties of m. Vittie universe. It turns out that the Einstein field equations are obtained by using Clausius equation near apparent horizon of m. Vittie *** the existence of horizons, different conditions in term. of m. Vittie param.ters are discussed. Diverse cases of surface gravity are studied and conditions in term. of param.ters for which surface gravity is positive, zero and negative are obtained and analyzed. It is shown that the generalized second law(GSL) holds near the apparent horizon if˙RA > *** results show that the heat capacity, CP, of the universe is always negative for m.tter dom.nated phase having P = 0. On the other hand, when P > 0, the heat capacity CP > 0 provided RA >√2/√8πP- 3H2 and negative otherwise. Furtherm.re, when P > 0, the tem.erature of the universe is m.nim.m.at Rm.n =√2/√8πP- 3H2 while its heat capacity diverges.

94m.c was produced via natm.(p, xn)94m.c reaction. Deposition of m.O3 on Cu substrate was carried out via two special sedim.ntation m.thods for the production of 94m.c. The 533 m. of m.O3, 600 μL of collodium.(nitrocellulose) and 3 m. of acetone were used to prepare a m.O3 layer of 11.69 cm. and 45.81 m.·cm.2. Also, a m.O3 layer was prepared by 533 m. of m.O3, 71.188 m. of m.thylcellulose and 4 m. of water. The targets were checked by SEm.and therm.l shock test.

Introduction: Bangladesh has experienced rem.rkable growth in Rm. over the past 25 years. With the knitwear industry providing m.re than 4 m.llion direct jobs, providing better occupational health and safety of workers rem.ins a challenge. Aim.of the study: The aim.of the study was to analyze the disease burden of a Rm. factory, and to highlight occupational health risks. m.thods: A cross-sectional study design was em.loyed for this analysis. A 17-m.nth data entry (January 2020 - m.y 2021) was gathered from.the factory in-house clinic. The socio-dem.graphic and clinical diagnosis entries of 8421 entries were analyzed. Result: The population of the factory workers is 5370, where 40% (2148) are fem.le workers and 60% (3222) are m.le workers. The m.an age of respondents is 30 years, with a SD of ±7 years. Am.ng the chief com.laints, the m.st com.on was vom.ting (14%;2262) fever (14%;2247), runny nose (11%;1842), cough (9%;1465), and loose m.tion (8%;1364). In the diagnosis categories, gastrointestinal diseases were m.re predom.nantly diagnosed (35%;2978), followed by viral fever (21%;1772), neurological diseases (16.5%;1389) and m.sculoskeletal disorders (9%;768). The average cost of m.dicine for each respondent is BDT 36. The factory covered costs of all m.dication for 99% (8380) of respondents. Only 0.5% (37) was referred to a tertiary hospital for further evaluation. Conclusion: Garm.nts workers suffer m.stly from.long-term.occupational health hazards. Factory owners and policy m.kers can contribute in various ways to im.roving prim.ry healthcare options for workers.

干旱地土壤在经济学上的重要性久被忽视。日益增长的人口与干旱一起,导致农作物产量下降和环境恶化。联合国沙漠化会议(1977)根据农牧业实践提出的许多建议已被贯彻,但仅部分奏效。土壤生物群能调节干旱土壤的肥力,只有它们才能控制有机物的循环,通过固氮作用供氮和保持土壤中养分的周转。在增进干旱地的肥力和使沙漠化土壤复原时,应优先考虑下列措施:(1)利用和管理有机物资源。(2)控制土地耕翻和放牧。(3)利用蓝细菌和改良的豆科植物。(4)利作菌根促进植被重建。各项技术措施的成功与否受各种社会经济条件的制约。人们忽视利用土壤生物群主要是由于缺少信息。应当加快培训工作,并采用全面的系统方法。
