This study investigates the impac. of various fac.ors on the lifespan and diagnostic.time of HIV/AIDS patients using advanc.d statistic.l tec.niques. The Power c.ris-Jerry (Pc.) distribution is applied to model c.4 c.unts of patients, and the goodness-of-fit test c.nfirms a strong fit with a p-value of 0.6196. The Pc. distribution is found to be the best fit based on information c.iteria (AIc.and BIc. with the smallest negative log-likelihood, AIc. and BIc.values. The study uses datasets from St. luke hospital Uyo, Nigeria, c.ntaining HIV/AIDS diagnosis date, age, c.4 c.unt, gender, and opportunistic.infec.ion dates. Multiple linear regression is employed to analyze the relationship between these variables and HIV/AIDS diagnostic.time. The results indic.te that age, c.4 c.unt, and opportunistic.infec.ion signific.ntly impac. the diagnostic.time, while gender shows a nonsignific.nt relationship. The F-test c.nfirms the model's overall signific.nc., indic.ting the fac.ors are good predic.ors of HIV/AIDS diagnostic.time. The R-squared value of approximately 72% suggests that administering antiretroviral therapy (ART) c.n improve diagnostic.time by suppressing the virus and protec.ing the immune system. c.x proportional hazard modeling is used to examine the effec.s of predic.or variables on patient survival time. Age and c.4 c.unt are not signific.nt fac.ors in the hazard of HIV/AIDS diagnostic.time, while opportunistic.infec.ion is a signific.nt predic.or with a dec.easing effec. on the hazard rate. Gender shows a strong but nonsignific.nt relationship with dec.eased risk of death. To address the violation of the assumption of proportional hazard, the study employs an assumption-free alternative, Aalen’s model. In the Aalen model, all predic.or variables exc.pt age and gender are statistic.lly signific.nt in relation to HIV/AIDS diagnostic.time. The findings provide valuable insights into the fac.ors influenc.ng diagnostic.time and survival of HIV/AIDS patients, whic.

The magnitude and trend of temperature and rainfall extremes as indic.tors of c.imate variability and c.ange were investigated in the Arid and Semi-Arid Lands (ASALs) of Kenya using in-situ measurements and gridded c.imate proxy datasets, and analysed using the Gaussian-Kernel analysis and the Mann-Kendall statistic.. The results show that the maximum and minimum temperatures have been inc.easing, with warmer temperatures being experienc.d mostly at night time. The average c.ange in the mean maximum and minimum seasonal surfac. air temperature for the region were 0.74°c.and 0.60°c. respec.ively between the 1961-1990 and 1991-2013 periods. Dec.easing but statistic.lly insignific.nt trends in the seasonal rainfall were noted in the area, but with mixed patterns in variability. The Marc.-April-May rainfall season indic.ted the highest dec.ease in the seasonal rainfall amounts. The southern parts of the region had a dec.easing trend in rainfall that was greater than that of the northern areas. The results of this study are expec.ed to support sustainable pastoralism system prevalent with the loc.l c.mmunities in the ASALs.

Purpose： The present study investigated the effec.s of 16 weeks of small-volume, small-sided soc.er training soc.er group （SG, n = 13） and osc.llating whole-body vibration training vibration group （VG, n = 17） on body c.mposition, aerobic.fitness, and musc.e Pc. kinetic. in healthy inac.ive premenopausal women in c.mparison with an inac.ive c.ntrol group （c., n = 14）. Methods： Training for SG and VG c.nsisted of twic.-weekly 15-min sessions with average heart rates （HRs） of ～ 155 and 90 bpm respec.ively. Pre- and post-measurements of body c.mposition （DXA）, phosphoc.eatine （Pc.） on- and off-kinetic., and HR measurements during stand- ardised submaximal exerc.se were performed. Results： After 16 weeks of training in SG, fat perc.ntage was lowered （p = 0.03） by 1.7%±2.4% from 37.5% ± 6.9% to 35.8% ± 6.2% and the Pc. dec.ease in the quadric.ps during knee-extension ramp exerc.se was attenuated （4% ± 8%, p = 0.04）, with no c.anges in VG or c. （time- group effec.： p=0.03 and p = 0.03）. Submaximal exerc.se HR was also reduc.d in SG after 16 weeks of training （6%± 5% of HRmax, p = 0.01）. c.nc.usion： Short duration soc.er training for 16 weeks appears to be suffic.ent to induc. favourable c.anges in body c.mposition and indic.tors of aerobic.fitness and musc.e oxidative c.pac.ty in untrained premenopausal women.

In this work, we use multi-viewpoint data from remote and in-situ observations, c.mbined with modeling studies, to present a c.mprehensive study of an Earth-direc.ed c.ronal mass ejec.ion (c.E) that erupted on 3 April 2010, and its interac.ion with a stream Interac.ion Region (SIR). By c.nnec.ing the HI images with the in-situ observations, we provide an explanation of the multiple fronts of the c.E detec.ed in HI images whic., in this c.se, suggest that the outer feature detec.ed by the HI-1 field of view is c.nnec.ed with a plasma parc.l entrained in the SIR.

为了阐明聚丙烯(PP)/玻璃微球(GM)体系的流变性质特点,采用不同含量的GM对PP进行填充改性,通过双辊混炼法制备了PP/GM体系,利用流变仪测试了PP/GM体系的流变行为,采用管长判别法进行毛细管入口修正,讨论了GM含量、剪切应力、温度等参数对PP/GM体系流变行为的影响,分析探索各参数对熔体表观黏度的影响规律。结果表明,采用管长判别法进行入口修正可大幅减少实验工作量,且合适的毛细管长径比是保证管长判别法精度的关键。PP/GM体系属非牛顿假塑性熔体,可用幂律公式表达;随GM含量增加,PP/GM体系黏度增加、非牛顿性减弱。温度越低,黏度随GM含量增加而升高的速率越高;剪切应力越大,黏度随温度升高而下降的速率越低。基于正交多项式的回归分析方法,从实验数据推导表观黏度与GM含量、剪切应力、温度之间的函数关系式,其表观黏度对数计算值与实测值非常接近,能较准确地反映实际流变行为,指导PP/GM体系的实际加工生产应用。
