大家已经知道,以推型金属带为基件的无级变速箱(CvTs)的传动效率低于速比间断变化的变速器这种倾向是用CvT由于发动机/负荷匹配得到的燃油经济性的好处有被抵消的趋势。本论文组三篇论文详细地阐述了作为第一级得到的改进效率的带传动中损耗机理的研究。接上述两篇论文本文对由于带组和带的推块之间的相对运动以及带轮和带由于带轮变形的影响发生转矩损失进行模拟分析。本文还描述了附加的实验研究,测出了变速器内两带轮的切向滑动速度。推荐了附加的损耗模型,基于目前其他推荐的理论外,阐述了除论文1和论文2的讨论外的带滑动现象。通过转矩损耗和论文1和论文2中推荐的转矩一力分布的相互作用对比实验范围证实了本文进行的有关分析。本文考虑到其他研究中的新发现,改变目前金属v带的设计。

Background and Study Aims: Portal hypertension often coexists with pancreatic pseudocysts and is potentially dangerous if a collateral vessel is in the vicini ty of the needle puncture pathway. Hitherto, there have been no reports of pseud ocyst drainage in this setting. Patients and Methods: Patients who underwent end oscopic ultrasound (EUS)-guided pancreatic pseudocyst drainage complicated by i ntervening vessels were assessed for success and outcomes. An Olympus mechanical linear-array video echo endoscope GF-UM 140D was used for the drainage proced ure in all patients. Either a “hot"diathermy technique was employed or a “cold " technique using direct aspiration with a 19-G needle, followed by deployment of a nasocystic catheter. Results: Eight patients with a symptomatic pseudocyst and intervening vessels underwent drainage that was guided (n = 6) or assisted ( n = 2) by EUS. All were found to have successful resolution of the cyst at follo w-up 6 weeks later, while segmental portal hypertension had disappeared in one patient. There were no major *** patient had transient hemorrhagic drainage that resolved by itself. Conclusions: Pseudocysts complicated by porta l hypertension or by intervening vessels can be safely drained under EUS guidanc e, even in the absence of color Doppler imaging.

Context: Despite the new recommendations “Test and Treat”, the virological and molecular parameters remain important information for Antiretroviral Treatment and adequate for monitoring of patients infected with HIv/AIDS. Objective: the Objective of this study is to present the virological and molecular profile of People Living with HIv starting Antiretroviral Therapy in Kinshasa in the era of the Dolutegravir. Methods: This was a transversal study to determine virological and molecular profile of People Living with HIv (PLHIv) starting an ARv Treatment. The patient’s inclusion period was from October 04, 2021 to February 15, 2022. A sample of 5 ml of blood was taken in a tube with EDTA anticoagulant for Molecular Biology analyzes (viral Load and Sequencing) in all HIv patients, after reading and signing informed consent. The population was made up of adult patients over the age of 18, infected with HIv and starting ART. Results: 119 patients (56.3% of women) were included in this study, thus a sex-ratio of 1.29. The average age of patients included was 39.87 ± 12.36 years. The most represented age group is that of 36 to 45 with 37 patients (31.9%) followed by that from 26 to 35 years with 24 patients (20.7%). Out of 119 patients, 21 patients had an undetectable viral Load (vL). The median value of vL was 4.16 log10 RnA copies/ml. 114 samples were successfully amplified. Subtype A was dominant with 23 cases (20.2%);followed by the subtype C and CRF02_AG each with 14.0%, and D (10.5 %). K65R (1.8%), T69P/n (4.4%), K70R (7.9%) and M184v (7.0%) mutations were listed as existing mutations for nucleotide Transcriptase Inhibitors. Conclusion: 38 patients (31.93%) started the TARv with a positive virological prognosis. The subtype A remains dominant in Kinshasa with 23 cases (20.2%);followed by the subtype C and CRF02_AG each with 14.0%. For Inhibitors of Transcriptase Reverse nucleotide;K65R, T69P/n, K70E/R and M184v mutations were found in patients’ naive of ARv Treatmen

世界核心医学期刊文摘（眼科学分册） 2006年第6期2卷 21-22页

作者： Dobson v. Quinn G. E. Summers C. G. 王大江(译) 不详 DepartmentofOphthalmology UniversityofArizona 655 N Alvernon Tucson AZ 85711 United States

Objective: To describe recognition (letter) acuity at age 10 years in eyes with and without retinal residua of retinopathy of prematurity (ROP). Design: Presence and severity of ROP residua were documented by a study ophthalmologist. Masked testers measured monocular recognition visual acuity (Early Treatment of Diabetic Retinopathy Study) when the children were 10 years old. Two hundred forty-seven of 255 surviving Cryotherapy for Retinopathy of Prematurity (CRYO-ROP) randomized trial patients participated. A reference group of 102 of 104 Philadelphia-based CRYO-ROP study participants who did not develop ROP was also tested. Results: More severe retinal residua were associated with worse visual acuity,regardless of whether retinal ablation was performed to treat the severe acute-phase ROP. However,within each ROP residua category,there was a wide range of visual acuity results. Conclusions: This is the first report of the relation between visual acuity (Early Treatment of Diabetic Retinopathy Study charts) and structural abnormalities related to ROP in a large group of eyes that developed threshold ROP in the perinatal period. visual deficits are greater in eyes with more severe retinal residua than in eyes with mild or no residua. However,severity of ROP residua does not predict the visual acuity of an individual eye because within a single residua category,acuity may range from near normal to blind.
