Abstract: Introduction: Malaria infection and HIV infection are major public health issues in several parts of the world. Together they have caused more than a million deaths per year. Africa, and Sub-Saharan in particular are the most affected. Our study objective is to determine the prevalence of Malaria/HIV co-infection and describe its immunological, virological, parasitic and biological characteristics. Methodology: This is a descriptive, transversal and multi centric study done on 18 years old and above HIV positive patients, for a period extending from December 2008 to October 2009 in 5 different HIV treatment centres. Parameters studied were gender, age, CD4 count, viral load, parasite density and haemoglobin level. The HIV diagnosis was made according to the AIDS National Program and malaria according to the Malaria National Program. Statistic analyses were done using Epi Info 7 software and the Yates corrected Chi Square test or the Fischer Exact test (when recommended) was used to check any link between different parameters studied. Statistical significance was fixed at <0.05. Results: 405 HIV seropositive patients were compiled. The malaria prevalence in these patients was 6.9%. Majority of co-infected patients were aged between 26 and 49 years (67.9%), and had a CD4 count <200 μl (67.9%), a parasitic density <10,000 trophozoites/μl (75%) and an Hb level <11 g/dl. With regards to correlations between co-infected patients parasitic density and the CD4 count, viral load and Hb level, none of the studied parameters showed any statistic significance difference. Conclusion: A prevalence of 6.9% among HIV/malaria co-infected patients and 67.7% of these patients had a CD4 count less than 200 cells/μl. Thus, both national programs must promote an early testing for HIV infected patients and reinforce preventive measures in the management of malaria.

Abstract:
Introduction: Tuberculosis and malnutrition are major health problems in DR Congo, and children are particularly vulnerable. The objective of this study is to determine the incidence of malnutrition in tuberculous children in DR Congo and to identify the associated factors. Methodology: A cross sectional study was conducted, and concerned 22 Tuberculosis Diagnosis and Treatment Centers (TDTCs). It was carried out over a period from 2013 to 2015 and involved 717 tuberculosis children less than 15 years of age. Nutritional status was assessed on the basis of the values of the Z-score Weight for age (global malnutrition) according to the NCHS curves. Results: Tuberculosis incidence was 8.2%. The prevalence of underweight (<﹣2 z-score) is 20.8%, of which 8.4% is severely malnourished (<﹣3 z-score). An age of less than 60 months is significantly associated with poor nutritional status (OR = 0.3, CI 0.2 - 0.5). TB-HIV co-infection is significantly associated with poor nutritional status (OR = 0.4, CI 0.2 - 0.6). It was noticed that the outcome is favorable (recovery) in patients with good nutritional status (OR = 12, CI 8.0 - 18.9). Conclusion: Underweight is present in Congolese tuberculosis children. An adequate nutritional policy is needed to improve the prognosis of the disease.

Abstract:
Introduction: The purpose of this study is to analyze the factors associated with nosocomial infections of caesarean section wounds in the maternity hospitals of the city of Mbuji-Mayi. Methods: This study was conducted in 25 maternities of general referral hospitals, clinics and hospitals in the city of Mbuji-Mayi during the period from 1 February to 1 June 2017, out of 171 parturients cesarized that were followed during a period of 4 months. A survey questionnaire was used to collect the data. Results: Out of 171 parturients monitored, surgical site infection developed 52 (SSI), an incidence of 30.4%. After analysis, nine factors were identified as associated post-caesarean SSI in Mbuji-Mayi city (p ≤ 0.05): age (p = 0.000), anemia (p = 0.000), prolonged duration of labor delivery (p = 0.001), premature rupture of the membranes before caesarean section (p = 0.044), prolonged duration after-rupture of the membranes (p = 0.000), preparation of the operative site by shaving (p = 0.029), surgery by general practitioner (p = 0.023), duration of operation greater than 60 minutes (p = 0.040), non-compliance with asepsis during dressing (p = 0.000). Conclusion: The fight against nosocomial infections must be a permanent concern: the prevention and regular monitoring of these infections must be the control strategies of each hospital structure, under the watchful eye of a coordination center for the fight nosocomial infections.
Tuberculose pulmonaire révélée par un purpura thrombopénique chez l’enfant - à propos d’un cas clinique observé au service de pédiatrie des Cliniques Universitaires de Lubumbashi

Pan African Medical Journal , 2012,
Abstract: Nous rapportons le cas d’un enfant de 7 ans, de sexe masculin ayant présenté un purpura thrombopénique avec épistaxis, hématémèse, otorragies et pétéchies généralisées. Durant la même hospitalisation, nous avons mis en évidence une tuberculose pulmonaire documentée par la présence de bacilles acido-alcoolo résistants à l’examen des crachats. Nous avons observé une majoration du taux de plaquettes en une semaine de corticothérapie intraveineuse à haute dose, avant l’instauration d’une poly chimiothérapie antituberculeuse. Nous rappelons également la controverse que suscite la prise en charge de cette association rarement rapportée.
The Effects of Social Interaction and Social Norm Compliance in Pay-What-You-Want Situations  [PDF]
Leon Paul Hilbert, Augustin Suessmair
American Journal of Industrial and Business Management (AJIBM) , 2015, DOI: 10.4236/ajibm.2015.58054
Abstract: Since Pay-What-You-Want is a relatively new field of study, the influence factors during the pricing process are not sufficiently explored. It was hypothesized that in a hypothetical Pay-What-You-Want situation, increased social interaction and social norm compliance would lead to a higher willingness to pay for a travel mug. In a laboratory experiment, 79 German students were randomly assigned to three groups which varied in the degree of social interaction. Social norm compliance was assessed with a questionnaire. A 3 × 3 between-group factorial ANOVA showed a significant main effect for social interaction (p = 0.025, η2 = 0.08), whilst social norm compliance was slightly not significant (p = 0.067, η2 = 0.03). Follow-up comparisons were calculated and the results discussed. The findings implicate that especially the degree of social interaction should be regarded, both by researchers and practitioners, as an important situational factor influencing the price in a Pay-What-You-Want situation.
Bernard Charlot y la práctica del saber
Mutuale,Augustin;
Educere , 2009,
Abstract: bernard charlot has thought in a different way about the role of practice and knowledge at school. he, in fact, through revisiting school achievements and not school failure opposes the current postures linked with the transmission of knowledge; for instance, those that consider the transmission as a ?banking? capital or better yet as a finished product that reduces pedagogy to a simple technique of learning. from radically questioning what learning means, bernard charlot is forced to consider knowledge as a process with its own shapes. the student he presents can disappear in objectivation. its schooling process is previewed from the sole angle of trajectory, meaning linear. but seen from the perspective of a construction, the schooling process turns devious in itself by integrating multiple senses, even contradictory or conflictive.

On The Group of Strong Symplectic Homeomorphisms
BANYAGA,AUGUSTIN;
Cubo (Temuco) , 2010, DOI: 10.4067/S0719-06462010000300004
Abstract: we generalize the ?hamiltonian topology? on hamiltonian isotopies to an intrinsic ?symplectic topology? on the space of symplectic isotopies. we use it to define the group ssympeo (m,ω) of strong symplectic homeomorphisms, which generalizes the group hameo(m,ω) of hamiltonian homeomorphisms introduced by oh and müller. the group ssympeo(m,ω) is arcwise connected, is contained in the identity component of sympeo(m,ω); it contains hameo(m,ω) as a normal subgroup and coincides with it when m is simply connected. finally its commutator subgroup [ssympeo(m,ω), ssympeo(m,ω)] is contained in hameo(m,ω).

Abstract: The paper describes methodology of numerical simulation of fatigue crack growth and its application on integrally stiffened panels made of 2024-T351 aluminium alloy using high speed cutting technique. Presented approach for crack growth simulation starts by the calculation of stress intensity factor function from finite element results obtained using MSC. Patran/Nastran. Subsequent crack growth analysis is done in NASGRO and uses description of crack growth rates either by the Forman-Newman-de Koning relationship or by the table lookup form. Three crack growth models were applied for spectrum loading: non-interaction, Willenborg and Strip Yield model. Relatively large experimental program comprising both the constant amplitude and spectrum tests on integral panels and CCT specimens was undertaken at the Institute of Aerospace Engineering laboratory in order to acquire crack growth rate data and enable verification of simulations. First analyses and verification tests of panels were performed under the constant amplitude loading. For predictions of crack growth using the spectrum loading a load sequence representing service loading of the transport airplane wing was prepared. Applied load spectrum was measured on B737 airplane within the joint FAA/NASA collection program. The load sequence is composed of 10 flight types with different severity analogous to the standardized load sequence TWIST. Before application on the stiffened panels a calculation of crack growth under the spectrum loading was performed for simple CCT specimen geometry. The paper finally presents comparison of simulations of fatigue crack propagation in two-stringer stiffened panel under the spectrum loading with verification test carried out in the IAE lab. The work was performed within the scope of the 6th Framework Programme project DaToN - Innovative Fatigue and Damage Tolerance Methods for the Application of New Structural Concepts.
