Inland f.shing predominates in the Kedougou region, which has no coastline. This type of.f.shing does not yet meet the local population’s demand f.r f.sh products. In response to this concern, a Community Agricultural Estate housing an integrated f.sh f.rm was set up in the commune of.Bandaf.ssi, in the village of.Itato. Since its creation, this production unit has been f.ced with the problem of.sourcing high-quality, low-cost, monosex male Oreochromis niloticus f.y. In order to overcome this constraint, the present research f.cuses on the contribution of.Garcinia kola to the productivity and economic prof.tability of.the Itato f.rm. The aim of.the research is to assess f.sh production in the experimental set-up and the production costs of.tilapia in a controlled environment. The comparative study of.the various production f.ctors shows disparities only in the input f.ctor, where scenarios 2 and 3 use additional products. These are 17-α-methytestosterone f.r scenario 2 and Garcinia kola f.r scenario 3. These products signif.cantly interf.re with f.sh production, with a f.irly high mortality rate f.r scenario 2 (25% f.r two production cycles/ cohort2 (B5, B6, B7 and B8) treated with 17-α-methytestosterone). As f.r scenarios 1 and 3, mortalities are 5% with or without recourse to additional products (G. kola). In addition, average f.sh production f.r the three (03) scenarios is estimated at 28687.5 kg/2 cycles. It varies f.om one scenario to another, i.e. 30937.5 kg/2 cycles f.r scenarios 1 and 3 and 24187.5 kg/2 cycles f.r scenario 2. It is theref.re higher in scenarios 1 and 3 than in scenario 2. This dif.erence is due to the f.irly large losses of.individuals in scenario 2. f.rthermore, the analysis of.the prof.t and loss accounts f.r tilapia production varies f.om one scenario to another depending on the type of.f.rm: 476 f.anc Cf. f.r scenario 1, 610 f.anc Cf. f.r scenario 2 and 472 f.anc Cf. f.r scenario 3 (f.Cf. = f.anc of.the f.ench Colonies of.Af.ica).

The aim of.this study was to evaluate the dose delivered to patients during scannographic examinations at the Kaolack Regional Hospital (one of.the 14 regions of.Senegal located in the center-west of.the country, 192 km f.om Dakar) and to compare these irradiation doses at diagnostic ref.rence levels f.und in the literature in order to optimize our scanning protocols. To achieve this goal, we carried out a prospective study involving 218 CT scans. These examinations f.cused on cerebral, thoracic, abdominopelvic and lumbar spine acquisitions made in adults and cerebral only in children. We compared the median values of.dosimetric indicators (CTDIvol and DLP) per acquisition with NRDs in the literature. During the course of.this study, we f.und a dosimetric ratio lower than that of.the NRDs f.r thoracic, abdomino-pelvic and lumbar spine CT scans in adults and a signif.cant dosimetric exceedance f.r brain scans in adults and in children. These results encourage us to extend these dosimetric evaluations to other hospital structures in order to establish rigorous monitoring of.dosimetric indicators and to respect the principles of.radiation protection and good practice.

The aim of.this article is to investigate the ef.ect of.dielectric loss tangent on f.equency dispersion of.output reactance and capacitance in GaAs *** this purpose,measurements of.output impedance modulus and phase have been carried out within a f.equency range of.10 Hz to 10 kHz,and various voltage values of.gatesource（Vgs= 0,-0.2,-0.3,-0.35,-0.4,-0.45,-0.5 and-0.6 V） and drain-source（Vds= 0.7,0.9,1,1.5and 2 V） Based on the concept of.complex permittivity of.semiconductor material,complex capacitance is used to analyze and simulate f.equency dispersion of.output reactance and capacitance of.GaAs *** results show that conductor losses which dominate the dielectric loss tangent are attributed to trapping mechanisms at the interf.ce of.devices;so they inf.uence the f.equency dispersion of.output reactance and capacitance in particular at low *** reveals that f.equency dispersion of.these parameters is also related to dielectric loss tangent of.semiconductor materials which af.ects the response of.electronic devices according to f.equency variation.

Stroke represents the 2nd cause of.mortality and 1st cause of.physical disability in the adult population. In Senegal, it represents 30% of.hospitalization and 2/3 of.the mortality in the department of.neurology in the capital city, Dakar. Objective: To specif. the types of.stroke and to evaluate diagnostic delays in Senegal’s regional hospitals. Materials and Methods: This was a retrospective, cross-sectional, descriptive, multicentric study f.r 4 years (f.om 2014 to 2017) including any patient presenting a clinical suspicion with a CT scan conf.rmation of.stroke in one of.the 9 regional hospitals in Senegal with a recruitment period of.6 months per hospital. CT scans were perf.rmed with a 16 slices machine in 6 hospitals, 4 slices in 2 hospitals and 2 slices in 1 hospital. We studied the types and location of.strokes, the associated signs and the time f.om stroke onset to admission and the time f.om admission to CT scan. Results: 655 patients were retained including 322 men and 333 women f.r an M/f.ratio of.0.96. The average age was 63 years (range: 7 years, 112 years). High blood pressure was noted in 59.2% of.patients and diabetes in 10.7% of.patients. Strokes were ischemic in 76% of.cases involving the middle cerebral artery in 73% of.cases and hemorrhagic in 24%, of.which 80.7% were deep localized. A mass ef.ect was noted in 7.5% of.cases, an engagement in 6.9% of.cases and ventricular hemorrhage in 2.7% of.cases. The delay between the onset of.the def.cit and admission was less than 6 hours in 10.6% of.patients. The time between the onset of.stroke and admission to hospital was specif.ed in 416 patients (63.5%) of.the study population, it was less than 6 hours in 10.6% of.patients, between 6 hours and 24 hours f.r 29.3% and more than 24 hours f.r 60.1%. Between admission and the CT scan, the time was precise in 459 patients (70%), it was less than 6 hours in 37.9%, between 6 hours and 24 hours in 43.6 % and more than

Quantal studies of.sodium 3p ← 3s photoabsorption spectra perturbed by ground lithium atoms

引用

Chinese Physics B 2019年第6期28卷 146-154页

作者： N Lamoudi f.Talbi M T Bouazza M Bouledroua K Alioua badji Mokhtar University B.P.12 AnnabaAlgeria Laboratoire LESIMS Laboratoire de Physique des Rayonnements Laboratoire LAMA Souk-Ahras University Souk-Ahras 41000Algeria

The pressure broadening in the f.r wings, where the sodium Na(3 p ← 3 s) resonance line is perturbed by ground lithium Li(2 s) atoms, has been theoretically analyzed. The NaLi potential–energy curves and the transition dipole moments are constructed by using a reliable ab initio data points to carry out the reduced-absorption coef.icients k_r(ν, T). This quantum-mechanical investigation have demonstrated that the NaLi prof.le spectra show a satellite f.ture in the red wing at wavelength λ = 685 nm in the temperature range 4000 K–1.8 × 10~4 K. The computation could also exhibit a second satellite, in the blue wing, near the wavelength λ = 574 nm beyond 6000 K and a third peak located at λ = 490 nm which begins to appear at 1.8 × 10~4 K.
