Introduction: Despite current progress, tuberculosis remains a major public health problem, given its still high incidence, prevalence, and mortality, particularly in sub-Saharan African countries, including Senegal. This risk is higher for immunocompromised people. Complications and comorbidities can also affect the course of the disease, affecting the prognosis. It is in this context that this study was undertaken with the objective of determining the risk factors and complications in patients hospitalized for tuberculosis. Materials and Methods: This was a retrospective and descriptive study carried out in 2021, from records of patients hospitalized for tuberculosis from January 1, 2017, to December 31, 2019, at the Pulmonology Department of Fann. Inclusion criteria were all patients on TB treatment after diagnosis of tuberculosis has been confirmed bacteriologically or clinically according to the World Health Organization’s TB case definition. Multidrug-resistant TB was excluded. Results: Out of 4516 hospitalized patients, 20.96% of patients were tuberculosis patients. The sex ratio was 2.18. 4/5 of the patients were between 18 and 39 years old. The main contributing factors of TB found were undernutrition (93.13%), active smoking (36.75%) and diabetes (35.97%). The time between hospitalization and onset of symptoms was greater than 2 months in 60.53% of cases. A complication was noted in 89.10% of patients, particularly bacterial/viral bronchopulmonary co-infection (31.15%). The trend was favorable in 88.49% of cases. It resulted in death in 10.98% of cases. Conclusion: Most integrated-care nutritional support programs focus on HIV. Undernutrition appears to play a much more important role than HIV in the extent of TB in poor countries. It creates a vicious circle with tuberculosis, one of the components of which is immunosuppression and the increased frequency of complications such as bacterial/viral community/nosocomial co-infection, the actual incidence of w

Introduction: Therapeutic patient education is a continuous, integrated, patient-centered process. A study was conducted in the Asthma School in the pneumophtisiology department of Senegal. Overall goal was to determine the influence of therapeutic education on the quality of life of asthmatics. Method: Transverse study, descriptive and evaluative therapeutic education provided in the school of asthma on quality of life for asthma patients. Data were analyzed through IBM SPSS (Statistical Package for Social Science) version 20. Results: 100 asthmatic patients were included with a sex ratio of 0.37. The average age of the patients was 36.76 years old. The majority (81.3%) (n = 39) being new participants. The average scores for symptoms, exposure to stimuli, emotions and limiting activities stay higher for adherent patients as well as the score overall quality of life. Conclusion: The school of asthma, associated with the therapeutic management, can improve the control of the disease and the quality of life of the patient.

作者： yacine LABBI Djilani Ben ATTOUS Belkacem MAHDAD Department of Electrical Engineering University of El-Oued El-Oued 39014 Algeria Department of Electrical Engineering University of Biskra Biskra 07000 Algeria

In recent years, various heuristic optimization methods have been proposed to solve economic dispatch （ED） problem in power systems. This paper presents the well-known power system ED problem solution consider- ing valve-point effect by a new optimization algorithm called artificial bee colony （ABC）. The proposed approach has been applied to various test systems with incremental fuel cost function, taking into account the valve-point effects. The results show that the proposed approach is efficient and robust when compared with other optimiza- tion algorithms reported in literature.

Nonlinear description of Yang-Mills cosmology： cosmic inflation and the accompanying Hannay's angle

Hannay＇s angle is a classical analogue of the ＂geometrical phase factor＂ found by Berry in his research on the quantum adiabatic theorem. This classical analogue is defined if closed curves of constant action variables return to the same curves in phase space after an adaibatic evolution. Adiabatic evolution of Yang-Mills cosmology, which is described by a time-dependent quartic oscillator, is investigated. Phase properties of the Yang-Mills fields are analyzed and the corresponding Hannay＇s angle is derived from a rigorous evaluation. The obtained Hannay＇s angle shift is represented in terms of several observable parameters associated with such an angle shift. The time evolution of Hannay＇s angle in Yang-Mills cosmology is examined from an illustration plotted on the basis of numerical evaluation,and its physical nature is addressed. Hannay＇s angle, together with its quantum counterpart Berry＇s phase, plays a pivotal role in conceptual understanding of several cosmological problems and indeed can be used as a supplementary probe for cosmic inflation.

Zinc oxide（ZnO） thin films were deposited on glass substrates by spray pyrolysis technique decomposition of zinc acetate dihydrate in an ethanol solution with 30 m L of deposition rate, the ZnO thin films were deposited at two different temperatures： 300 and 350℃. The substrates were heated using the solar cells *** substrate was R217102 glass, whose size was 30×17.5×1 mm^3. The films exhibit a hexagonal wurtzite structure with a strong（002） preferred orientation. The higher value of crystallite size is attained for sprayed films at 350℃, which is probably due to an improvement of the crystallinity of the films at this point. The average transmittance of obtain films is about 90%–95%, as measured by a UV–vis analyzer. The band gap energy varies from 3.265 to 3.294 e V for the deposited Zn O thin film at 300 and 350℃, respectively. The electrical resistivity measured of our films are in the order 0.36 Ω·cm.

Classical state feedback controller for nonlinear systems using mean value theorem： closed Ioop-FOC of PMSM motor application

引用

Frontiers in Energy 2015年第4期9卷 413-425页

作者： Abrar ALLAG Abdelhamid BENAKCHA Meriem ALLAG Ismail ZEIN Mohamed yacine AYAD LGEB Laboratory Department of Electrical Engineering University of Biskra Biskra BP 145 Algeria R&D Industrial Hybrid Vehicle Applications Belfort 90010 France

The problem of state feedback controllers for a class of Takagi-Sugeno （T-S） Lipschitz nonlinear systems is investigated. A simple systematic and useful synthesis method is proposed based on the use of the differential mean value theorem （DMVT） and convex theory. The proposed design approach is based on the mean value theorem （MVT） to express the nonlinear error dynamics as a convex combination of known matrices with time varying coefficients as linear parameter varying （LPV） systems. Using the Lyapunov theory, stability conditions are obtained and expressed in terms of linear matrix inequalities （LMIs）. The controller gains are then obtained by solving linear matrix inequalities. The effectiveness of the proposed approach for closed loop-field oriented control （CL-FOC） of permanent magnet synchronous machine （PMSM） drives is demonstrated through an illustrative simulation for the proof of these approaches. Furthermore, an extension for controller design with parameter uncertainties and perturbation performance is discussed.
