A halotolerant, gram positive, motile and rod, was isolated from the E1 Gol6a lake of Ghardaia, Alegria and screened for its antimicrobial potential. The strain showed an inhibitory effect to gram positive and gram negative bacteria against Cladosporium spp. and a slight inhibitory effect against C. albicans using chloroform as the extraction solvent and the nutrient broth as production medium. 16S rRNA sequencing showed that the isolate named LMB3981 is a new taxon in the family of Bacillaceae （with 96% similarity）. The strain is close to Filobacillus milosensis and Bacillus haloalkaliphilum with 95% similarity. The phenotypic study showed differences between LMB3981 and two strains that are near and have confirmed the results of 16S rRNA sequencing by specific metabolic properties of the strain.

Research on organic solar cells has a craze importance because they show very interesting properties including their flexibility and the opportunity to be made into large surfaces. However, their stability and performance should be significantly improved compared to their current state. A nominal output of around 10% will be the goal for the coming years. The use of organic materials for photovoltaic applications is the subject of intense research in recent years. This work is based in part on the development of new conjugated polymers. In this paper, we present the synthesis and characterization of poly [(thiophene-2,5-diyl)-co-(benzylidene)] PTB catalysed by Maghnite-H+, used in the active layer of the solar cell organic heterojunction with PCBM (derivative of C60) was used as a junction of the solar cell: Glas/ITO/BCP/C60/PTB/Au/Al. A current density of short circuit of about Jcc 0.1mA/cm2 was obtained for this structure with a yield of around 0.15%.

We develop the discrete derivatives representation method (DDR) to find the physical structures of the Schr?dinger equation in which the interpolation polynomial of Bernstein has been used. In this paper the particle swarm optimization (PSO for short) has been suggested as a means to improve qualitatively the solu-tions. This approach is carefully handled and tested with a numerical example.

到2010年,拉丁美洲的能源需求将达到677百万吨石油当量,比1995年增加50％。1995～2010年,拉丁美洲地区用于铺设天然气管道和液化天然气项目的费用将达190亿美元。该地区很多国家将改进自己的政策、法律和管理制度,以吸引所需投资。目前,该地区正在实施或筹划的几个主要天然气项目是:哥伦比亚的Enron管线、秘鲁的卡米塞阿项目、从阿根廷到智利诺瓦管线、玻利维亚—巴西管线等。世界银行组织一直协助该地区许多国家建立一种竞争性的商业环境,通过担保制度对几个复杂的大型跨国项目提供贷款。

Lightening structure is one of the goals of many fields of research. As a result, magnesium alloys are studied due to their low density. However, one drawback of these alloys is their low formability at room temperature due to their hexagonal closed-packed structure. In the present work, the forming capacity of an AZ31 Mg alloys has been studied using a mini deep-drawing device, image correlation techniques and tests (tension and expansion) at temperatures contained between 20°C and 200°C. To investigate formability limits of Mg alloys in expansion, major and minor strains data were generated using hemispherical punch tests and analyzed with 3D digital images correlation techniques. Thanks to images correlation, strains on the surface of the samples were observed by means of a double digitization of the sample in three dimensions before and after deformation by using stereoscopic vision and triangulation. Image correlations have also been used in 2D to measure strains on the surface of the tensile test samples. These tests gave interesting information on the evolution of various parameters such as hardening coefficient, strain rate sensitivity parameter, and Lankford coefficient, which may affect the behavior of the alloys. Finally, the forming limits in both configurations (tension and expansion) were compared and discussed.

Objectives： Infectious tricuspid endocarditis is known to simply require antibiotherapy and to have good prognosis in most cases. Few studies focused on severe episodes managed in ICU. We aimed to describe clinical and microbiological features, and fmal outcome of infectious tricuspid endocarditis managed in ICU. Methods： From 1 January 2009 to 31 August 2017, all patients hospitalized in intensive care unit with infectious tricuspid endocarditis were enrolled. Key findings： We collected 15 episodes of infectious tricuspid endocarditis. Median age was of 39 years. Risk factors were： intravenous drug users （n = 10）, pace maker （n = 1）, vascular device （n = 2）, none （n = 2）. Median SAPS II, APACHE II and SOFA on admission were 21, 10 and 2 respectively. Organ failures on admission were： acute respiratory failure （n = 10）, sepsis （n = 7）, coma （n = 1） and acute kidney injury （n = 8）. The most frequent causative pathogen was Staphylococcus Aureus. Antibiotherapy failure happened in 10 patients from whom 8 underwent cardiac surgery （53.3%）. Most frequent complications were acute kidney injury （n = 14） and withdrawal syndrom. Infectious tricuspid endocarditis relapse on bioprosthesis occurred within 2 intravenous drug users after hospital discharge. Overall in-hospital mortality was 40%. Conclusions： Infectious tricuspid endocarditis in ICU is fitted with poor prognosis and high need to cardiac surgery. Special care should be provided to intravenous drug users to prevent relapse.

Thyroid cancer is relatively rare, about 1% of all cancers combined. However, it accounts for 88% of all cancers of the endocrine organs. In recent years, the incidence of thyroid cancer has increased considerably compared to other types of endocrine cancers. The aim of our work is to study the epidemiological profile of thyroid cancer in the western part of Algeria and to determine the influence of sex, age and histological type. Patients and methods: Our study focuses on 1376 cases of thyroid cancer in patients attending the nuclear medicine department at the university hospital of Tlemcen over a period of 3 years, from 2013 to 2015. The average age of patients is estimated at 43. Each patient underwent an anatomo-histopathological examination of the surgical specimen. The data entry is done through the SPSS 20 statistical software. Results: The rates of the thyroid cancers listed during the three years of studies (2013-2014-2015) are 32.12%, 34.44% and 33.43% respectively. Our study shows that the female sex is largely incriminated (94.75%) compared to the male sex. The age group mostly affected was that ranging from 40 to 60 with 45.88%. The anatomo-histopathological analysis revealed that the papillary carcinoma is the most frequent histological type with 85.47% followed by the vesicular carcinoma with 14%, the medullary cancer MTC with 0.43%, and finally the anaplastic carcinoma with 0.07%. Conclusion: the epidemiological surveillance contributes to a better knowledge of thyroid carcinoma allowing a good patient management in Algeria. Early detection of small size cancers and the use of high-performing technologies will result in a decrease of the mortality rate associated to this type of cancer.
