Abstract: Introduction: The family planning policy aims to bring women in sexual activity to the use of modern methods of contraception. But, despite the many initiatives aimed at this improvement, modern contraceptive prevalence is still low. The objective of this study was to evaluate the knowledge and practices of contraception by the inhabitants of Kansele Health Zone. Methods: Our study was cross-sectional with an analytical focus on 249 randomly selected subjects and over a period from July 30 to September 30, 2021. The survey method and interview technique, as well as the questionnaire as an instrument were used to collect the data. The univariate and bivariate analysis was performed and the odds ratios with their 95% CIs were calculated. The significance level was set at p < 0.05. Results: The majority of respondents were in the age group of 21 to 26 years (38.55%). The female sex was predominant (87.95%); there were many participants with good knowledge (92.37%), but only half of the respondents, i.e. 51.30%, had used contraceptive methods during the last 12 months. The following variables were associated with low contraceptive use: occupation (OR = 2.6633, IC [1.4240; 4.7100], p = 0.0421); the level of study (OR = 2.4922, IC [1.4672; 4.2673], p = 0.0003) and the desired inter-birth interval (OR = 2.0221, IC [1.321; 4.147], p = 0.0386). Conclusion: Improvement in modern contraceptive practice in the Kansele health zone (city of Mbujimayi) must necessarily go through an ambitious and well-coordinated program. This program should focus on raising awareness, coupled with offering a wide range of contraceptive products at affordable costs.
On the Causes of the Minor Dry Season over the Coastal Region of the Northern Gulf of Guinea  [PDF]

Atmospheric and Climate Sciences (ACS) , 2018, DOI: 10.4236/acs.2018.82009
Abstract: Along the littoral shelf of northern coast of the Gulf of Guinea (GG), a minor dry season of the rainfall regime is concomitantly observed with the occurrence of a major coastal upwelling in July-August-September (JAS). It was then supposed that this upwelling drives that minor dry season. But no previous studies have tried to understand this minor dry season and, this study is the first focusing on this question. The investigations undertaken to explain this dry season on the Ivorian littoral shelf with the ERA-Interim data from the European Centre for Medium Range Weather Forecasts over the 1980-2016 period have shown that the minor dry season is driven by the Northward migration of the Inter Tropical Convergence Zone (ITCZ) during this period and, enhanced by the occurrence of the major coastal upwelling of the northern GG at the same time. These two phenomena interact as follow: i) the ITCZ is located in JAS far in the north cutting off convective processes along the coast, ii) the air on the coastal region is poor in humidity, iii) the air temperature on the bordering region of the GG is cooled by the coastal upwelling to value less than 26°C and not favorable for providing convection.
Seasonal Variability of the Buoyancy Flux along the Northern Coast of the Gulf of Guinea  [PDF]

Atmospheric and Climate Sciences (ACS) , 2021, DOI: 10.4236/acs.2021.112021
Abstract: The buoyancy flux Bo at the air/sea interface is very useful to understand the variability of the stratification of the mixed layer, the oceanic mixing, the phytoplankton dynamics and then the coastal upwelling. The atmospheric reanalysis ERA5 and the oceanic reanalysis ORAP5 data have been used in this study to describe the sea surface Bo and, its influence on the variability of the mixing in the mixed layer and consequently on the coastal upwelling along the northern coast of the Gulf of Guinea. The Bo is negative along the coast and, is characterized by a seasonal variability dominated by the thermal buoyancy flux. This study has also shown that the mixing layer is very shallow along the coast and deeper offshore. The negative value of the Bo increases the stratification of the mixed layer and reduces the mixing. This could explain why the mixed layer is shallow in this region. This work suggests that an increasing trend of the global warming could have dramatic impact in this area by increasing the stratification in the mixed layer and would contribute to reducing the coastal upwelling intensity.

Open Journal of Obstetrics and Gynecology (OJOG) , 2018, DOI: 10.4236/ojog.2018.812119
Abstract: Objective: To identify the epidemiologic profile of the woman having practiced the clandestine abortion, to determine the frequency and the complications of the clandestine abortion and to evaluate the prognosis of the clandestine abortion in our area. Method: The present study is descriptive and retrospective covering the period from January 2017 to December 2017, the one year period. On 118 patients received in the service for clandestine abortion, 60 were retained for the study. The 58 other files were excluded because of not containing sufficient information for this study. The descriptive statistical analyses were applied for the data analysis. Results: The frequency of the allowed patients for complication of clandestine abortion caused at the Saint Joseph hospital of Kinshasa was 6.03%. The most concerned population with this practice was less than 15 years and more than 45 years; they were unmarried (41.6%) and nulliparous (41.6%) in most cases. Ancillary medical staff (especially nurses) was accused the most in this practice of the illegal abortion caused by the dilatation and curettage with 50%. The genital haemorrhage constitutes the principal complication and reason for consultation and accounted for 78.3%. The assumption of responsibility is primarily medical and surgical. The vital prognosis is satisfactory for the immediate one, because no

Abstract: Education makes it possible to pass from one generation to another, the culture necessary for the development of the personality and the social integration of the individual. Education contributes closely to the supervision of students and remains the responsibility of educators and education inspectors. But each education staff admits the number of students supported. This number is two hundred and eighty (280) students per educator and one thousand two thousand (2000) per education inspector. Our study aims at taking stock of the adequacy between school enrollment and education staff enrollment from a WebSIG for vocational training schools in Côte d’Ivoire. To achieve this, the methodology adopted led us to use the MERISE analysis method for setting up the database, web programming languages (HTML 5, PHP, CSS, XML and JavaScript), AJAX technology, Apache web server, DBMS (MySQL), Google Maps API. The results from the use of WebSIG highlight the disparity in the distribution of education personnel. These results also show which schools remain in need as well as in excess.

Optics and Photonics Journal (OPJ) , 2011, DOI: 10.4236/opj.2011.12013
Abstract: Excited state lifetimes of C60/toluene solution and C60 films macromolecular were measured by pump-probe method. Relation between optical switching effect of material and pulse width of pumping field is briefly described. It is found that the faster switching speed of light is, the triplet state lifetime is shorter. A He-Ne laser, as a probe, passed through the sample in the pump-probe experiment. All-optical switching effect was realized. Changing the optical power of the pumping field, switching response of the sample and modulation depth were investigated. In certain experimental conditions, relation between transmission through the sample and response were measured by an oscilloscope. Triple state lifetime of the molecule is speculated. The result showed that C60/toluene solution and C60 film have a fast response time. They would be utilized in some applications, such as optical switches, photonic devices.

Journal of Tuberculosis Research (JTR) , 2024, DOI: 10.4236/jtr.2024.121003
Abstract: This study investigates the health implications of sharing a shisha (hookah) mouthpiece during smoking, with a focus on tuberculosis (TB) and hepatitis prevalence in Sub Saharan Africa. It examines shisha smoking behavior patterns and associated risks of disease transmission among those sharing a common mouthpiece. Through literature review and empirical data analysis, the research highlights epidemiological factors driving TB and hepatitis transmission within the context of shisha smoking in Sub Saharan Africa. Exploring cultural, social, and behavioral determinants influencing shisha mouthpiece sharing, the study offers insights into interventions and public health strategies. It emphasizes the need for targeted health education campaigns, policy interventions, and community-based initiatives to promote safer smoking practices. Immediate coordinated public health interventions, including educational campaigns and regulatory measures, are recommended. Collaboration among healthcare professionals, policymakers, and communities is essential. These insights deepen the understanding of challenges posed by communal shisha smoking in Sub Saharan Africa, laying the groundwork for evidence-based interventions to reduce TB and hepatitis transmission and enhance overall health outcomes in the region. This research underscores the urgency of addressing the risks

Abstract: The present study was undertaken to evaluate in vitro antifungal activity of aqueous and hydroacoholic extracts from bark of Terminalia ivorensis A. Chev. (Combretaceae). In vitro antifungal activity of all the extracts was done by agar slant double dilution method. Candida albicans and Aspergillus fumigatus clinically important strains were used for the study. ketoconazole was used as standards for antifungal assay. Antifungal activity was determinated by evaluating of antifungal parameters values which are MCF (minimal concentration fungicide) and IC50 (Concentration for 50% of inhibition) around each assay. Result showed that the antifungal activity was more pronounced against Aspergillus fumigatus than Candida albicans. The hydroalcoholic extract showed best antifungal activity than ketoconazole. Demonstration of antifungal activity of T. ivorensis provides the scientific basis for the use of this plant in the traditional treatment of diseases and may help to discover new chemical classes of antifungal substances that could serve as selective agents for infectious disease chemotherapy. Keywords: Terminalia ivorensis, antifungal activity, clinical strains, hydroalcoholic extract [J Intercult Ethnopharmacol 2013; 2(1.000): 49-52]
Low-pressure methanol/ dimethylether synthesis from syngas on gold-based catalysts

Gold Bulletin , 2007, DOI: 10.1007/BF03215584
Abstract: The hydrogenation of carbon monoxide over Au/ZnO catalysts has been re-examined and new data is presented on the way in which the product distribution can be manipulated by choice of coadded solids such as alumina or zeolite-Y. This comparative study reveals that while ZnO itself leads to a high selectivity to methanol, the incorporation of gold drastically alters the product spectrum and leads to a very high selectivity to hydrocarbons. The hydrocarbon selectivity at a reaction temperature of 300oC is in fact much higher than in the case where alumina or zeolite-Y is introduced into a composite catalyst comprising the Au/ZnO and the acidic solid. In the latter case DME is a major product. Significant light hydrocarbon formation on gold-based systems under these circumstances appears not to have been discussed before. The reactions taking place on these catalysts, the selectivities and absolute activities are discussed and the role of gold highlighted.
