On the Causes of the Minor Dry Season over the Coastal Region of the Northern Gulf of Guinea  [PDF]
Angora Aman, Elisee Toualy, Fidele Yoroba
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.

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
Determination of the Triplet State Lifetime of C60 /Toluene Solution and C60 Thin Films by Pump-Probe Method  [PDF]
Cheng Bao Yao, Elisee Kponou, Yun Dong Zhang, Jin Fang Wang, Ping Yuan
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 Intercultural Ethnopharmacology , 2013, DOI: 10.5455/jice.20121205083931
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]
Development of an Integrated Coastal Vulnerability Index for the Ivorian Coast in West Africa  [PDF]

Journal of Environmental Protection (JEP) , 2018, DOI: 10.4236/jep.2018.911073
Abstract: This study assesses the vulnerable state of the 566-km Ivorian coastal area using the physical (geomorphology, coastal slope, coastal retreat rate, relative sea level rise and wave/Tide energy) and socio-economic (coastal population density, harbor, airport, road, land use and protected area) factors as indicators. This enabled an Integrated Coastal Vulnerability Index to be determined for the Ivorian coastal zone. This Index could be defined as the weighted average of indexes based on physical and socio-economic factors. The study revealed that vulnerability of the western and the eastern coastlines of Cote d’Ivoire are strongly influenced by human activities, while physical forcing affects significantly the vulnerability of the central section. The relative vulnerability of the different sections depends also strongly on the geomorphology, wave energy, coastal population density and land use factors. The west and central sections of the coastline are more resilient than the eastern section when integrating physical and socio-economic factors. The Integrated Coastal Vulnerability Index, based on physical and socio-economic factors, appears to be more appropriate for coastal vulnerability assessment. These results could be useful in the development of adaptation strategies to increase the resilience of this coastal area and then extended for West Africa Coastal Areas Management.

Abstract: The boreal summer upwelling along the northern coast of the Gulf of Guinea (GG) is characterized using new in situ sea surface temperature (SST) from onset sensor and satellite TRMM Microwave Imager (TMI) datasets. This study aims to encourage intensive in situ SST measurements at the northern coast of the Gulf of Guinea. It shows good agreement between daily in situ SST and TMI SST and similar coastal upwelling onset date, end date, and durations calculated using both datasets. Interannual evolution of the onset date at four stations along the northern coast of GG indicates that the upwelling can be initiated at one cape or simultaneously at both the cape of palms and the cape of three points. It can be also initiated eastward towards Cotonou or globally off all the northern coasts of GG. Nonsignificant trend is found on upwelling onset date and end date variability. Moreover, this study shows that SST is significantly warm or cold some years. Ocean conditions during these years are related to known physical processes. 1. Introduction Coastal upwellings are characterized by seasonally low sea surface temperature (SST). They generally result from the response of the coastal ocean to alongshore winds, leading to the production of a relatively intense current with a small offshore and a large alongshore component [1]. This causes the pumping of cooler and nutrient-rich waters from the subsurface to the ocean surface. Upwelling areas are economically important even though the global area constituted by these regions is less than 1% of the global ocean [2]. Moreover, coastal upwellings have a great impact on local climate. Particularly, the coastal ocean surface conditions in the Gulf of Guinea situated in the northeastern equatorial Atlantic influence the West African climate [3]. Understanding the ocean dynamic of this region is then of great interest, (i) firstly because the Gulf of Guinea is the principal source of the water vapour which constitutes most of the precipitation on the continent. For example, Gu and Adler [4] linked the rainfall peak in May along the coastal area of the Gulf of Guinea to the seasonal forcing of the ocean. Eltahir and Gong [5] observed that the intensity of the West African monsoon depends on the meridional gradient of the static humid energy in the boundary layer between the ocean and the continent. (ii) Secondly, this tropical Atlantic area has the largest SST seasonal amplitude of about 5–8°C [6]. A coastal upwelling is observed each year along the northern coast of the Gulf of Guinea during the boreal winter and summer

Abstract: Amyotrophic lateral sclerosis (ALS) is a rare but serious neurodegenerative disease characterized by progressive muscular paralysis without overall achievement of higher functions, resulting from motor neuron destruction. The present study reports two cases of elderly female patients aged 45 and 54 years, respectively, allowed for a progressive motor deficit of 4 members. Neurological examination found a spastic pyramidal syndrome and a neurogenic syndrome device of 4 members without sensory syndrome. The ENMG revealed a pure motor neurogenic compatible with involvement of the anterior horn of the spinal cord, holding the ALS diagnosis. The standard radiography and cervical MRI were normal. These patients received analgesics, nursing, physiotherapy and psychotherapy. Then they were lost. ALS is a rare disease (incidence: 1.25%). Our patients, with a mean age of 54.5 years, showed clinical and laboratory signs associated with them classically encountered. The diagnosis is suspected in a spastic pyramidal syndrome and neurogenic peripheral syndrome of 4 members but not eliminate cervical spondylotic myelopathy one. The ENMG confirms it. Although the treatment is disappointing, it’s based on the riluzole and palliative care, but the evolution is inexorably toward death.
