Abstract:
Introduction: Thanks to the scientific publication information may be essentially known inside the scientific work and those publications are taking the primordial place in researching. It’s thanks to the publication that a performance of a high teaching facility and university is assessed. Objective: This research is aimed to scientific productions work of teachers of Lubumbashi Nursing College from March 2006 up to April 2018. Methods: We have used the descriptive and bibliographic methods. The data were collected using the questionnaire method and the documentary analysis. Out of one hundred and twenty (120) scientific and academic personals, only thirty nine (39) have fulfilled the condition required to participate research. So, in the period of twelve years, we have collected sixty eight (68) scientific productions. Outcome: We have noticed a disproportion between the number of the teachers who should produce and the number of publication that have been produced. Secondly, we’ve also noticed the irregularity of put that is out of one hundred twenty scientific teachers; we realized fourteen (14) articles which were published by the female teachers against to fifty four (54) produced by the male teachers. This is to say that in the international magazine ten (10) articles were published and fifty eight (58) were produced locally. This irregularity of publishing is due to the fact that research is able to publish unless (there is a promise of promotion) his expecting to be promoted. Otherwise, publication became sometimes non-existent. Conclusion: A teacher who is also a researcher has to publish and inform others about his researches. The work done by ISTM of Lubumbashi Teachers during the period of twelve years has produced sixty eight (68) articles for thirty mine (38) writers. Not more than half has been published. And we come to realize that writers have last the interest of publishing.

Journal of Emerging Trends in Computing and Information Sciences , 2012,
Abstract: Cloud computing promises to bring substantial benefits to how organizations conduct their businesses and the way their services reach out to potential consumers. Cloud computing is a welcome initiative for small businesses that cannot afford to invest in ICT infrastructure but need to benefit from the rewards of conducting business online. In developing economies, there are challenges that face cloud services providers and their consumers. Broadband network access was identified as the main essential service for a successful cloud computing offering. The objective of this paper is to give background information on the security issues in cloud computing, and highlight the potential of cloud computing and the associated challenges in utilizingservices on the cloud for small businesses in developing economies. We discuss security concerns specifically related to the small businesses, such as service availability, privacy and SLA terms
Une journée dans la vie d’Augustine Amaya d’Emmanuel Dongala : l’ identité de la femme africaine et du peuple congolais

Voix Plurielles , 2010,
Abstract: La femme a un r le central dans Jazz et vin de palme d’Emmanuel Dongala, surtout dans la nouvelle intitulée Une journée dans la vie d’Augustine Amaya. Par le biais du personnage d’Augustine Amaya et du processus de création littéraire, l’auteur explore la relation homme-femme, ainsi que le statut et l’identité de la femme dans la société centre-africaine. Dongala nous présente une image de la femme en tant que mère du peuple, et aussi belle qu’elle soit, elle reflète aussi le paradoxe de la femme noire. Cette image idéalisée de la femme sera analysée dans cet article et comparée à celle que Camara Laye présente dans L’Enfant noir, Maryse Condé dans Moi Tituba Sorcière et Alice Walker dans In Search of our Mother’s Gardens.

Abstract: Background: Tuberculosis (TB) and HIV are major public health problems in Botswana. In the face of growing TB notification rates, a low cure rate, human resource constraints and poor accessibility to health facilities, Botswana Ministry of Health decided to offer home-based directly observed treatment (DOT) using community volunteers. Objectives: The aim of this study was to assess the outcomes of home-based directly observed treatment (HB-DOT) versus facility-based, directly observed treatment (FB-DOT) in the Kweneng West subdistrict in Botswana and to explore the acceptability of HB-DOT among TB patients,community volunteers and health workers. Method: A quantitative, observational study using routinely collected TB data from 405 TB patientswas conducted and combined with 20 qualitative in-depth interviews. Results: The overall cure rate for smear-positive pulmonary TB patients was 78.5%. Treatmentoutcomes were not statistically different between FB-DOT and HB-DOT. Contact tracing was significantly better in FB-DOT patients. Interviews revealed advantages and disadvantages for both FB and HB options and that flexibility in the choice or mix of options was important. A number of suggestions were made by the interviewees to improve the HB-DOT programme. Conclusion: HB-DOT is at least as good as FB-DOT in terms of the treatment outcomes, but attention must be given to contact tracing. HB-DOT offers some patients the flexibility they need to adhere to TB treatment and community volunteers may be strengthened by ongoing training and support from health workers, financial incentives and provision of basic equipment.

Journal of the South African Veterinary Association , 2012, DOI: 10.4102/jsava.v75i2.459
Abstract: Studies covering all aspects of bovine viral diarrhoea virus (BVDV) have been conducted in several countries in Europe, Asia and America. In southern Africa, more information is required about the nature of BVDV infection, the prevalence of different strains and the economic importance of the disease. The presence of BVDV in southern Africa has been known since the early 1970s through serological surveys but few reports confirming its presence by virus isolation and correlation with clinical disease are available. Specimens (n = 312) collected in 1998/99, from live and dead cattle from different farming systems, were obtained from private practitioners, feedlot consultants and abattoirs throughout the country. Specimens (n=37) from African buffaloes (Syncerus caffer) in the Kruger National Park were also included. All specimens were processed for virus isolation in cell culture with confirmation by means of immunofluorescent antibody tests and some also by means of an antigen capture ELISA. BVDV was isolated from 15 (4.7 %) cattle and were all noncytopathic biotypes. BVDV was not detected in 37 lymph nodes obtained from buffaloes in the Kruger National Park. Of the clinical signs in cattle from which virus were isolated, respiratory signs was the most frequent (10/15), followed by diarrhoea (5/15). Abortion, congenital malformations, haemorrhagic diarrhoea and poor growth were also included as criteria for selection of animals for specimen collection, but no BVD viruses were isolated from cattle manifesting these clinical signs.

Abstract: The presence of bovine viral diarrhoea virus in South Africa has been confirmed by several serological surveys. However, little is known about its biological properties. Twenty five isolates obtained by isolation in tissue culture and detected by means of the antigen capture ELISA from clinically sick cattle and from foetal calf serum in South Africa were characterized on the basis of analysis of the 5' non-translated (NTR) region of the genome. A reverse-transcription polymerase chain reaction (RT-PCR) was used to amplify specific sequences from the 5'NTR of the genome. The oligonucleotide primers corresponding to positions 105-125 and 399-378, respectively, in the sequence of BVDV strain NADL were used to generate the PCR products. Both strands were sequenced directly with these primers and fluorescence-labelled dideoxynucleotides in an automated nucleic acid sequencer. Reference strains of pestiviruses [(BVDV type I, BVDV type II, border disease virus (BDV) and hog cholera virus (HCV)] and isolates from a previous investigation on BVDV in southern Africa were included for comparative purposes. All the BVDV strains obtained during this study belong to subgroups of BVDV genotype I. No association could be demonstrated between the geographic origin of the isolates. A number of isolates formed another branch separate from the existing branches Ia, Ib and Ic. These findings suggest that extensive genetic diversity can be found within BVDV type I isolates from southern Africa. Isolates that group with the classical BVDV type I strains, particularly of American origin, coexist with variants that appear to represent a local genetic pool and or variants evolving from the classical strains.

Journal of Cancer Therapy (JCT) , 2014, DOI: 10.4236/jct.2014.52020
Abstract:

Background: Several Phase III randomized trials have demonstrated improved local control and survival for post-mastectomy radiotherapy in patients with high-risk pathologic features. Close or involved surgical margins were not included as high-risk in these protocols, but have been associated with increased risk of local failure; however, the impact of a boost dose following chestwall radiotherapy in this setting remains to be determined. Methods: Retrospective single-institution outcomes analysis for patients with close or involved surgical margins treated with post-operative radiotherapy is followed by a boost. Results: Between 2003 and 2011, 34 patients were identified for inclusion in the present study. The median chestwall dose was 5040 cGy (range 5000 - 5040) and median boost dose was 1080 cGy (900 - 1620). At a median follow-up of 38.4 months (10.2 - 115.6; with 29% more than 5 years), 28 patients were alive without evidence of recurrence, 3 were alive with recurrent disease (1 chestwall), and 3 had died (none with recurrent disease). The 3-year local control, disease-free survival, and overall survivals were 96.9%, 93.9%, and 93.1%, respectively. Conclusion: Chestwall radiotherapy plus boost results in low risk of early locoregional recurrence for women with close or involved surgical margin(s) at mastectomy. Further investigation of PMRT with or without boost in this setting is warranted.

Abstract:

Inhibitory compounds are often found to be the leading cause of anaerobic reactor upset and failure since they are present in substantial concentration in wastewaters and organic solid wastes. Among these inhibitory compounds, organic compounds are mentioned and more especially aromatic compounds. The purpose of this work was to evaluate the effect of bisubstituted aromatics functional groups on the methanogenic inhibition. The toxicity to acetoclastic methanogenic bacteria has performed in serum flasks, utilizing digested pig manure as inoculums, by measuring cumulative methane production. The results obtained indicate that some general relationships exist between the bisubstituted aromatic structures and their inhibitory effects on methanogenic bacteria. This demonstrates sufficiently that the grafting of hydrophobic or hydrophilic substituent on the benzene or monofunctional aromatic compound, make the obtained compound more or less toxic as the case and that in the same order of toxicity. A significant correlation was obtained indicating that the partitioning of bisubstituted aromatics into lipophilic membranes in bacteria may have a role in the inhibition of methane biosynthesis.
