Introduction: Viral hepatitis B and C constitute real public health problems worldwide. The objective of this work was to describe the epidemiological, clinical and paraclinical aspects of viral hepatitis B and c in the internal medicine department of Kara University Hospital. Method: this was a retrospective descriptive study carried out in the Internal Medicine department of Kara University Hospital, over a period of 3 years from March 2020 to April 2023. It included all patients seen in consultation or hospitalized for hepatitis viral B and/or C. Results: A total of 57 patients were included in our study. The average age was 44.30 years ± 16.75 and the M/F sex ratio was 1.38. Married people were in the majority 63.2%. The circumstances of the discovery of viral hepatitis B and C were dominated by abdominal pain in 35.1% of cases and hepatomegaly in 29.8% of cases and in 33.3% of cases, it was during screening voluntary. Patients with viral hepatitis B only accounted for 64.9% of cases;those with only viral hepatitis C represented 31.6% of cases and 3.5% of cases had HVB/HCV co-infection. We recorded 36.8% complications including 52.4% liver cirrhosis and 47.6% hepatocellular carcinomas. During the evolution, there were 03 deaths. Conclusion: the prevalence of hepatitis B and C virus carriage in patients followed in internal medicine at Kara University Hospital is high. It is therefore essential to put in place treatment and prevention strategies against these viruses. 展开更多

Universal Soil Loss Equation (USLE) is the most comprehensive technique available to predict the long term average annual rate of erosion on a field slope. USLE was governed by five factors include soil erodibility factor (K), rainfall and runoff erodibility index (R), crop/vegetation and management factor (C), support practice factor (P) and slope length-gradient factor (LS). In the past, K, R and LS factors are extensively studied. But the impacts of factors C and P to outfall Total Suspended Solid (TSS) and % reduction of TSS are not fully studied yet. Therefore, this study employs Buffer Zone Calculator as a tool to determine the sediment removal efficiency for different C and P factors. The selected study areas are Santubong River, Kuching, Sarawak. Results show that the outfall TSS is increasing with the increase of C values. The most effective and efficient land use for reducing TSS among 17 land uses investigated is found to be forest with undergrowth, followed by mixed dipt. forest, forest with no undergrowth, cultivated grass, logging 30, logging 10^6, wet rice, new shifting agriculture, oil palm, rubber, cocoa, coffee, tea and lastly settlement/cleared land. Besides, results also indicate that the % reduction of TSS is increasing with the decrease of P factor. The most effective support practice to reduce the outfall TSS is found to be terracing, followed by contour-strip cropping, contouring and lastly not implementing any soil conservation practice. 展开更多

In this paper we define and study chain conditions for Hilbert C*-modules through their C*-algebras of compact operators and discuss their perseverance under Morita equivalence and tensor products. We show that these chain conditions are passed from the C*-algebra to its Hilbert module under certain conditions.

C语言和单片机是高等院校电子类专业本科阶段开设的两门非常重要的专业基础课和专业课,两者应是前后承接,是基础与应用的课程接续关系。但是,在传统教学过程中,由于两门课程衔接的不连贯,使得学生对于C语言的编程应用,特别是单片机方向的C51编程存在很大问题。该文针对这两门课程开展研究,重点在于“架起一座桥”,使得C语言与单片机课程的衔接更加连贯,学习效果更加完整。通过分析C语言课程教学现状,设计并实施基于单片机任务导向的C语言课程强化教学改革,改革课程评价指标,实施并总结教学经验,持续推进后续改革计划。该文所研究内容,无论是对于学生在校阶段的课程学习、毕业设计,还是对于其毕业后从事研究工作或者学业深造,都有极其重要的意义。 展开更多

Background: In India, tuberculosis (TB) is a major public health problem, and the advent of drug resistance TB (DR-TB) has worsened the situation. The Revised National TB Control Programme (RNTCP) has introduced universal drug susceptibility testing (UDST) for all diagnosed TB cases in 2018. We conducted this study to know the advantage of implementing UDST when compared to selective testing existent in 2017 on key diagnostic cascade parameters and to identify the challenges in the implementation of UDST. Methods: The study was conducted in two districts of Karnataka, India during January 2017-December 2018. The quantitative part consisted of before-and-after design and the qualitative part consisted of descriptive design. Results: In 2017 (during selective testing/“before” period) out of the 2440 TB patients, 80 (3%) were diagnosed with Isoniazid and Rifampicin resistance patients;in contrast in 2018 (during UDST/“after” period) of the 5129 TB patients 258 (5%) were diagnosed with Isoniazid and Rifampicin resistance. However, the proportion of eligible patients tested for rifampicin resistance during the “after” period was 60% when compared to 100% during the “before” period and median turnaround time for testing was also longer during the “after” period when compared to the “before” period (32.5 days vs 27.5 days). Major reasons for these two gaps were found to be difficulties in collecting sputum specimens and transportation. Conclusion: The rollout of UDST has led to a three-fold increase in a number of DR-TB cases detected in the region. There is a need for the programme to increase the proportion tested for DST by increasing the laboratory capacity and address the challenges in sputum collection and transportation. 展开更多

Suppose A is a unital C*-algebra and r 1.In this paper,we define a unital C*-algebra C(cb)*(A,r) and a completely bounded unital homomorphism αr:A → C(cb)*(A,r)with the property that C(cb)*(A,r)=C*(αr(A))and,for every unital C*-algebra B and every unital completely bounded homomorphism φ:A→ B,there is a(unique)unital *-homomorphism π:C(cb)*(A,r)→B such thatφ=πoαr.We prove that,if A is generated by a normal set {tλ:λ∈Λ},then C(cb)*(A,r)is generated by the set {αr(tλ):λ∈Λ}.By proving an equation of the norms of elements in a dense subset of C(cb)*(A,r)we obtain that,if Β is a unital C*-algebra that can be embedded into A,then C(cb)*(B,r)can be naturally embedded into C(cb)*(A,r).We give characterizations of C(cb)*(A,r)for some special situations and we conclude that C(cb)*(A,r)will be "nice" when dim(A)≤ 2 and "quite complicated" when dim(A)≥ 3.We give a characterization of the relation between K-groups of A and K-groups of C(cb)*(A,r).We also define and study some analogous of C(cb)*(A,r). 展开更多
