为防止高温材料的腐蚀,需要通过氦气净化系统对气冷堆回路中各种气体杂质含量进行控制。本文基于高温氧化铜床、室温分子筛床和深冷活性炭床的氧化以及吸附成熟技术,通过比较分析当前各国已有的典型氦气净化回路设计,提出一项改进设计方案。计算结果表明,在保证系统净化效率的前提下,改进设计不增加系统设备,可以明显地降低系统能耗。对回热器回热度的敏感性分析结果表明,回热器回热度并非越高越好。

A short 220 bp sequence was used to study the taxonomic organization of the bacterial Order Bacillales. The nucleotide sequences of the 3’ end of the 16S rDNA and the 16S-23S Internal transcribed spacer (ITS) were determined for 32 Bacillales species and strains. The data for 40 additional Bacillales species and strains were retrieved directly from Genbank. Together, these 72 Bacillales species and strains encompassed eight families and 21 genera. The 220 bp se- quence used here covers a conserved 150 bp sequence located at the 3’ end of the 16S rDNA and a conserved 70 bp sequence located at the 5’ end of the 16S-23S ITS. A neighbor-joining phylogenetic tree was inferred from comparative analyses of all 72 nucleotide sequences. Eight major Groups were revealed. Each Group was sub-divided into sub-groups and branches. In general, the neighbor-joining tree presented here is in agreement with the currently accepted phylogeny of the Order Bacillales based on phenotypic and genotypic data. The use of this 220 bp sequence for phylogenetic analyses presents several advantages over the use of the entire 16S rRNA genes or the generation of extensive phenotypic and genotypic data. This 220 bp sequence contains 150 bp at the 3’ end of the 16S rDNA which allows discrimination among distantly related species and 70 bp at the 5’ end of the 16S-23S ITS which, owing to its higher percentage of nucleotide sequence divergence, adds discriminating power among closely related species from same genus and closely related genera from same family. The method is simple, rapid, suited to large screening programs and easily accessible to most laboratories.

Introduction: Rabies, a neglected disease, could be grossly underreported in the DRC;in the absence of post-exposure prophylaxis, the WHO estimates that this disease would cause 327,000 deaths per year in Africa and Asia. The objective of this study is to determine the epidemiological profile of this zoonosis in order to encourage decision-makers to develop national strategies for its elimination. Materials and Methods: We conducted a cross-sectional descriptive study. Data collection was done retrospectively and in total6 420 victims of bites received during the period between January 2005 and December 2015 at the anti-rabies center in Lubumbashi were included in this work. Excel 13 software and Epi info 3.3.4 were used for data analysis and interpretation. Results: People over the age of 15 are the main victims of canine bites (62.1%), more than half of the victims are male (55.9%);dogs represent the majority of biting animals (96.4%) of which around 3/4 are unvaccinated (71.37%). Two municipalities are more affected: Lubumbashi (prevalence 83.35/100,000 and Kampemba (Prevalence 51.74/100,000). LBite peaks were observed from July to October (p = 0.01). For the 34 people seen with clinical signs of rabies encephalitis (confirmed case of rabies), the case fatality rate was 100%. Conclusion: Rabies is a major problem in Lubumbashi but its extent is different depending on the municipality. The dog is the main biting animal and the vaccination coverage of dogs remains very low. Access to rabies vaccine for bite victims is difficult. Its elimination remains possible through the implementation of an extensive canine vaccination program, the awareness of owners and the large-scale provision of post-exposure prophylaxis.

Near-infrared germanium(Ge) photodetectors monolithically integrated on top of silicon-on-insulator substrates are universally regarded as key enablers towards chip-scale nanophotonics, with applications ranging from sensing and health monitoring to object recognition and optical communications. In this work, we report on the highdata-rate performance pin waveguide photodetectors made of a lateral hetero-structured silicon-Ge-silicon(Si-Ge-Si) junction operating under low reverse bias at 1.55 μm. The pin photodetector integration scheme considerably eases device manufacturing and is fully compatible with complementary metal-oxide-semiconductor technology. In particular, the hetero-structured Si-Ge-Si photodetectors show efficiency-bandwidth products of^9 GHz at-1 V and ~30 GHz at-3 V, with a leakage dark current as low as ~150 nA, allowing superior signal detection of high-speed data traffic. A bit-error rate of 10-9 is achieved for conventional 10 Gbps, 20 Gbps, and25 Gbps data rates, yielding optical power sensitivities of-13.85 dBm,-12.70 dBm, and-11.25 dBm, respectively. This demonstration opens up new horizons towards cost-effective Ge pin waveguide photodetectors that combine fast device operation at low voltages with standard semiconductor fabrication processes, as desired for reliable on-chip architectures in next-generation nanophotonics integrated circuits.

Background and Objective: HIV infection is often associated with HBV and HCV infection, together leading to high morbidity and mortality in developing countries. The objective of this study is to describe the clinical, biological, immunological and therapeutic profile of patients co-infected with HIV-HBV and/or HCV. Methods: A cross-sectional and descriptive study including 180 people living with HIV (PLWHIV) in the city of Kinshasa province was conducted. Socio-demographic, clinical, biological and serological characteristics were analyzed. Results: The frequency of HIV-HBV/HCV co-infection was 23.9%. The distribution of age and sex of patients did not differ significantly according to co-infection status. The notion of pedicure and manicure was significantly more observed in patients free from viral hepatitis (51.1% versus 32.6%, p = 0.034). The median duration of knowledge of the HIV status which was longer in the co-infected (4 years versus 2 years, p = 0.022). A lower median level of GPT was observed in co-infected compared to other patients (14 IU/L versus 20 IU/L, p = 0.041). Serum albumin (3.1 g/L versus 3.3 g/L, p = 0.034) and prothrombin (58.3% versus 65.6%, p = 0.045) were lower in HIV co-infected-VHB and/or VHC. The median INR was higher in co-infected than in other patients (1.6 versus 1.4;p = 0.009). Patients without therapy Antiretroviral (TARV) medication were more numerous in co-infected (20.9% versus 8.0%, p = 0.025). Conclusions: The profile of PLWHIV was dominated by the presence of pedicures and manicures with high transaminases and without anti-viral treatment.

In our study, the Dominance-based Rough Set Approach (DRSA) has been proposed to assist the Board of Directors of the Community Futures Development Corporations (CFDC), the sub-region of Abitibi-West (Quebec). The CFDC needs a tool for decision support to select the projects that are proposed by the contractors and partners of its territory. In decision making, a balanced set of 22 indicators is considered. These indicators derive from five perspectives: economic, social, demographic, health and wellness. The DRSA proposal is suitable for the data processing with multiple indicators providing on many examples to infer decision rules related to the preference model. In this paper we show that decision rules developed with the use of rough set theory allow us to simplify the process of selecting a portfolio for sustainable development by reducing a number of redundant indicators and identifying the critical values of selected indicators.
