Fungal interdigital tinea pedis are poorly documented in Ivory Coast. This study aimed to determine the distribution of fungal species and contributing factors of the disease among policemen in Abidjan. Our cross-sectional study was carried out at the police school in Abidjan. Our patients consisted of symptomatic or non-symptomatic police students. Samples of scales or serosities taken from inter-toes spaces were examinated with KOH mount and cultured on Sabouraud-chloramphenicol and Sabouraud-chloramphenicol-actidione media. The method of identification depended on the observed fungus. Among the 303 police students with clinical lesions of the inter-toe folds, 233 (76.9%; IC 95%=71.9-81.4) had a positive diagnosis after mycological examination. Lesions were predominantly located in the 3rd and 4th interdigital plantar spaces, with desquamation (100%) followed by maceration (82.5%) as the predominant functional sign. Dermatophytes accounted for 86.3% of the strains isolated with as majority species : Trichophyton interdigitale (40.3%), Microsporum langeronii (30.0%) and Trichophyton rubrum (15.5%). Yeasts accounted for 13.7% of the strains with Candida albicans (7.7%) as the most found species. The duration at the police school (P=0.004) and the practice of sports activities (P=0.0001) were statistically associated with the occurrence of the disease. A good hygiene of feet would reduce the incidence of the disease among the defense and security forces. Also, investigations for the influence of the seasons in the occurrence of interdigital tinea pedis will allow a better understand of epidemiology of this dermatomycosis.

Access to cervical margins allows the practitioner to record the entire cervical margin in order to provide a true copy to the technician. This requires a gingival displacement obtainable by different techniques. This study aimed to assess the implementation of gingival displacement methods prior to impression taking in fixed prosthodontics. This is a descriptive and cross-sectional survey of sample of 71 dentists practising in Abidjan, Ivory Coast; which ran from October 2nd, 2010 to November 14th, 2010. A survey form was administered to dentists. The questionnaire was organised around the following headings: identification of dentists and practice of gingival displacement methods. The data processing done using software Epi Info 6 and Excel XP on Window XP, allowed calculation of frequencies, means and proportions and the establishment of connection between variables with the chi2 test. The significance level was set at p < 0.05. The results of the survey indicate that non-surgical methods of gingival displacement, including retraction cords and temporary crowns are those they use most frequently (76.4%) because the vast majority of practitioners (87.22%) believe the most traumatic to the periodontium are surgical methods. Our study showed that the gingival displacement methods are frequently carried out in daily practice, regardless of the topography of the abutment teeth and their number, but with a preference for non-surgical methods, particularly those using retraction cords and temporary crowns. The use of injectable gingival displacement paste is not harmful to the periodontal tissues, easy to use and have a very efficient haemostatic action. It should also be known and practiced.

Eutrophication increases methane emission to the atmosphere in tropical lagoons: insights from two Ivory Coast sites. Y J M Koné (1) & A.V. Borges (2) (1) Centre de recherches océanologiques (CRO) d'Abidjan, (Ivory Coast) (2) University of Liège, Chemical Oceanography Unit, Liège, Belgium (Belgium) Eutrophication is a worldwide environmental problem and a definitive solution is far from being achieved, despite the large number of studies documenting its causes. In small aquatic ecosystems, excessive growth of macrophytes is a well known undesirable consequence of eutrophication. When these plants die and sink to the bottom the decomposing biomass depletes oxygen content in the water column thus leading to anoxia promoting methane (CH4) production. Here, we reported the CH4 data obtained during six campaigns covering the annual cycle in two small lagoons of Ivory Coast (Ono, Kodjoboué) that are contrasted in the degree of eutrophication and the corresponding coverage of macrophytes (e.g. Echinochloa pyramidalis, Eichhornia crassipes, Hydrilla verticillata). Our data showed a high spatio-temporal variability of CH4 within the lagoons and between the two systems, with CH4 concentrations in surface waters ranging between 80 to 74,604 nmol L-1. The highest CH4 concentration values were observed in the eutrophic Ono lagoon that is covered by 80% of macrophytes, suggesting that lagoons dominated by macrophytes are significant sources of CH4 toward the atmosphere.

To evaluate serologic testing algorithms for human immunodeficiency virus (HIV) based on a combination of rapid assays among persons with HIV-1 (non-B subtypes) infection, HIV-2 infection, and HIV-1–HIV-2 dual infections in Abidjan, Ivory Coast, a total of 1,216 sera with known HIV serologic status were used to evaluate the sensitivity and specificity of four rapid assays: Determine HIV-1/2, Capillus HIV-1/HIV-2, HIV-SPOT, and Genie II HIV-1/HIV-2. Two serum panels obtained from patients recently infected with HIV-1 subtypes B and non-B were also included. Based on sensitivity and specificity, three of the four rapid assays were evaluated prospectively in parallel (serum samples tested by two simultaneous rapid assays) and serial (serum samples tested by two consecutive rapid assays) testing algorithms. All assays were 100% sensitive, and specificities ranged from 99.4 to 100%. In the prospective evaluation, both the parallel and serial algorithms were 100% sensitive and specific. Our results suggest that rapid assays have high sensitivity and specificity and, when used in parallel or serial testing algorithms, yield results similar to those of enzyme-linked immunosorbent assay-based testing strategies. HIV serodiagnosis based on rapid assays may be a valuable alternative in implementing HIV prevention and surveillance programs in areas where sophisticated laboratories are difficult to establish.

Urban development and employment in Abidjan.
Joshi, H; Lubell, H; Mouly, J
1975-04-01
The city of Abidjan in the Ivory Coast has grown physically, economically, and demographically at rates exceeding all reasonable expectation. Yet, as in many other development nations, the employment generated by Abidjan's rapid economic expansion has failed to keep pace with the increase in working population it has attracted. Consequently, economic success has been accompanied by a variety of social strains. Some of these have been discussed in earlier issues of the "International Labour Review" by Louis Roussel. This discussion expands on Roussel's earlier treatment by focusing more specifically on several facets of the urban employment problem created by the rapid growth of Abidjan. Attention is directed to labor supply and employment, factors affecting migration, foreign Africans in the Ivory Coast labor force; the urban informal sector; urban infrastructure and development; social problems of population pressure; employment policy options (current government policies and other policy options); and general issues and policy alternatives (motivations for rural urban migration, smaller urban centers as alternative growth poles, and distributing the gains from development). Several essential features of the employment problem stem from the rural urban distribution of the workforce. The rural labor force, including temporary seasonal workers from the savannah countries to the north, remains more or less in balance with increasing rural employment opportunities, since the migration of Ivory Coast nationals to the cities is balanced by the inflow of foreign workers. In contrast, the influx of migrants into urban areas has led to a more rapid increase in the urban labor force than in urban employment, with a consequent rise in unemployment. In 1970 the Abidjan rate of open unemployment was probably around 20%. At this time, most people's idea of a desirable job is one in the formal sector of the urban economy. If there is to be any hope of an eventual balance between

Seven rapid diagnosis tests (RDTs) of HIV were evaluated by a panel group who collected serum samples from patients in Abidjan (HIV-1 = 203, HIV-2 = 25, HIV-dual = 25, HIV = 305). Kit performances were recorded after the reference techniques (enzyme-linked immunosorbent assay). The following RDTs showed a sensitivity of 100% and a specificity higher than 99%: Determine, Oraquick, SD Bioline, BCP, and Stat-Pak. These kits were used to establish infection screening strategies. The combination with 2 or 3 of these tests in series or parallel algorithms showed that series combinations with 2 tests (Oraquick and Bioline) and 3 tests (Determine, BCP, and Stat-Pak) gave the best performances (sensitivity, specificity, positive predictive value, and negative predictive value of 100%). However, the combination with 2 tests appeared to be more onerous than the combination with 3 tests. The combination with Determine, BCP, and Stat-Pak tests serving as a tiebreaker could be an alternative to the HIV/AIDS serological screening in Abidjan.

We described the use of antiretroviral drugs to prevent HIV transmission among children and adolescents victims of rape in Abidjan (Ivory Coast). We conducted a retrospective and descriptive study on children (0-9 years) and adolescents (10-19 years) victims of rape between 2000 and 2013. We analyzed the patients' socio-demographic characteristics and the modality of the chemoprophylaxis. We included 10 children and 89 adolescents in the study. The median age was 16 years old (3-19 years). The median time to consultation was 23.5 hours (5-152 hours). The antiretroviral chemoprophylaxis was administered to 92 patients (93%). No HIV and HBV seroconversion was observed after a 3-month follow-up. A better management of rape victims is required in Abidjan. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

This study was conducted from 2008 to 2013 to determine the animal health status of Ivory Coast and neighboring countries (Burkina Faso, Ghana, Togo and Benin) for African swine fever (ASF) and classical swine fever (CSF), and to assess the risk factors for ASF introduction in Ivory Coast. Ivory Coast had probably been free from ASF from 1998 to 2014 when it was re-introduced in this country. However, the ASF virus was found in all neighboring countries. In contrast, no evidence of CSF infection was found so far in Ivory Coast and neighboring countries. To assess the risk of ASF reintroduction in Ivory Coast, we surveyed 59 modern pig farms, and 169 pig owners in 19 villages and in two towns. For the village livestock, the major risk factor was the high frequency of pig exchanges with Burkinabe villages. In the commercial sector, many inadequate management practices were observed with respect to ASF. Their identification should enable farmers and other stakeholders to implement a training and prevention program to reduce the introduction risk of ASF in their farms. Copyright © 2016 Elsevier B.V.

STUDY'S AIM: This study aims a more efficient follow-up of the safety of medicines with human usage on the Ivory Coast territory. The structure responsible for pharmacovigilance in Ivory Coast i.e. DPM listed the medicinal alerts from 2001 till 2010. It emerges 237 medicinal alerts among which 145 stops of marketing, 55 withdrawals of lots, 33 information notes and 4 levying of suspension of medicines. These alerts result mainly from pharmaceutical companies (49%) and the French Drug Agency or ANSM (ex-Afssaps) (43%). They mainly concern drugs of infectious target (22%) and pneumology (18%) and their motivations are so much industrial with mainly commercial reasons (27%) as of pharmacovigilance dominated by unfavorable profit/risk connections. These results constitute an important database for the survey of the medicines market in Ivory Coast and an additional motivation to accelerate the implementation of a real national center of pharmacovigilance. © 2012 Société Française de Pharmacologie et de Thérapeutique.

The aim of the presented study was to investigate the mycotoxin exposure of Ivorian population related to the consumption patterns of maize, peanuts, millet, and cassava product (attiéké). Maize flour samples (n = 51) were purchased from all Abidjan local markets, in the south of Ivory Coast, and urine (n = 99) was collected during the same reference period (July-September 2011) from volunteers living in Abidjan and Daloa cities. Reversed-phase liquid chromatography coupled with electrospray ionization triple quadrupole mass spectrometry (LC-ESI-MS/MS) was used to analyze aflatoxins (AFB1, AFB2, AFG1, and AFG2), ochratoxin A (OTA), fumonisins (FB1, FB2), deoxynivalenol (DON), zearalenone (ZEA), and T-2 and HT-2 toxins in maize flour samples, and their relevant biomarkers (AFM1, DON, DON + de-epoxydeoxynivalenol (DOM-1), FB1, α-zearalenol (ZOL), β-ZOL, and OTA) in urine samples. Critical maize contamination was observed by AFs occurrence (total AFs 4.5 - 330.0 μg/kg) while OTA was found in 13% of samples analyzed. AFM1 was detected in 40% of urines samples (0.06 - 14.11 ng/ml), OTA in 37% (0.01 - 0.42 ng/ml), FB1 in 27% (0.07 to 15.31 ng/ml) and, DON was found in 21% of samples at levels up to 10.0 ng/ml. The correlation coefficients (R(2)) obtained by plotting the percentage of biomarker occurrence (positive samples) versus the frequency of food consumption revealed maize, peanuts, millet and attiéké were strongly linked to AFB1 and OTA exposure with values of R(2) ranged from 0.462 to 0.956. The present study provided data on mycotoxin risk in Ivory Coast, revealing a frequent co-exposure to the major mycotoxins such as AFs, OTA, and fumonisins, which appeared to be related to the frequency of peanuts, maize, millet and attiéké consumption.

Abidjan like numerous African cities is experiencing a significant and uncontrolled population growth. The annual growth rate is estimated at 3.99% by the National Institute of Statistics. This rapid population growth also generates growing needs in general and especially for drinking water and economic activities. In the District of Abidjan, groundwater comes from the Mio-Pliocene age aquifer called "Continental Terminal". This unconfined aquifer is the main source of water supply. Its lithology consists of four levels. Actually only the two upper levels outcrop and constitute the main part of the Continental Terminal aquifer. Some recent studies report a potential overexploitation and pollution of Abidjan groundwater (Jourda, 1986, Kouame 2007, Deh, 2013). This deterioration in water quality could be due to the release of domestic and industrial waste water, pesticide and fertilizer from crops and toxic waste sites containing high doses of organochlorines, of hydrogen sulfide and sulfides. This risk is also linked to the economic activities such as car workshops, gas stations and the sand exploitation in the lagoon. To observe the likely evolution of such contaminants in the subsurface and we developed hydrogeological models that couple groundwater flow and transport with FEFLOW software. The model is composed of a sandy layer where two constant hydraulic heads of 55 m and 0.2 m are imposed on the north and the south respectively. We carried out grain size analysis of some samples (E2, E3, E4, E5, and E6) which shows particle size ranging between 0.0001 mm and 8 mm. This grain size analysis performed by sieving underwater and laser indicates that these five soils are: loamy sand with traces of clay and gravel for E2 and E5; Sandy loam with traces of clay for E3; Sand with traces of clay and gravel for E4 and Sand with traces of silt and clay for E6. Their porosity and average values of permeability coefficient K measured in the laboratory range from 0.2 to 0

In the first half of the XXth century, while Upper-Volta (now Burkina Faso) was suffering a terrible epidemic of sleeping sickness, the French colonial administration encouraged the movement of people from Upper-Volta to Ivory Coast to meet their demands for labour. This led to the establishment of Mossi villages, such as those of Koudougou, in the Ivorian forest with populations originating from areas of Upper-Volta that were not only densely populated but also severely affected by sleeping sickness. Since 2000, most cases of sleeping sickness in the Koudougou district of Burkina Faso have been in people originally from Ivory Coast. Who are they? Where did they settle in Burkina Faso? Where do they come from in Ivory Coast? After having retraced the epidemiological history of Koudougou villages in Burkina Faso and Ivory Coast, the history of ten cases of sleeping sickness detected passively at Koudougou hospital since 2000 were analysed. All cases originated from the forest area of Ivory Coast. Understanding the spread of sleeping sickness between Burkina Faso and Ivory Coast will assist in the identification of areas of disease risk.

Fourteen Ivory Coast tektites exhibit a range of bulk indices of refraction of 1.5156 to 1.5217 ?? 0.0004 and of bulk specific gravities of 2.428 to 2.502 ??0.005. Seven of these Ivory Coast (IVC) tektites were analyzed for major and minor element content. Compared to tektites from other strewn fields, their SiO2 content is low (67.2-69.1 %), A12O3 relatively high (15.8-16.8 %), and total iron relatively high but with a more restricted range (6.3-6.8 % as FeO). Their lime content is low (0.71-1.35%) compared to Australasian tektites but their MgO CaO ratio (about 3.1) is unusually high. All other tektite groups have Na2O K2O ratios less than unity, but the Na2O K2O ratio of the IVC tektites is slightly greater than unity. Their K Rb ratios range from 200 to 256 and average 227, which is higher than those determined for Australasian tektites, but similar to some obtained for moldavites. The Li content (41-48 ppm) is about the same as that of the Australasian tektites, but the Cs and Rb are lower, being 1.9 to 2.9 and 57 to 86 ppm, respectively. The IVC tektites are high in Cr (260-375 ppm), Co (19-25 ppm) and Ni (101-167 ppm), and particularly in Pb (<10-18 ppm), Cu (13-21 ppm) and Ga (14-23 ppm). The high Cr Ni ratios of the IVC tektites (range 2-3.6) are similar to those found for australites, philippinites and thailandites, but not the javanites and indochinites. Evaluation of these and other reported data show that compositional similarities between the IVC tektites and green or black Bosumtwi Crater glasses strongly support the hypothesis of a common impact origin-i.e. the Bosumtwi Crater site. Comparison of the IVC tektite composition with those of returned lunar materials (gabbros, basalts, breccia and soils) do not support a lunar origin for the Ivory Coast tektites. ?? 1972.

Within less than a quarter century diabetes has become a health problem in developing countries. In Africa this metabolic disorder is found in a wide variety of sometimes atypical forms. The purpose of this study was to highlight the special epidemiological features of medically diagnosed diabetes in Ivory Coast. Data from the files of 10320 African patients who presented at a major national outpatient care centre between January 1, 1991 and December 31, 2000 were compiled and analyzed. Findings showed that morbidity gradually increased from 30 to 49 years then stabilized from 50 to 69 years with a higher rate in males between 30 and 49 years. One of the five national ethnic groups appeared to be most affected and two appeared to be relatively unaffected. On the basis of several criteria, 5968 patients were classified as type 1 in 11.8% of cases, type 2 without excess body weight in 48.7% and type 2 with excess body weight in 39.5%. The second of these identified groups was characterized by intermediate-discovered glycaemia and older age at diagnosis. Epidemiological features included age of occurrence and higher morbidity in young male patients, probable higher premature mortality, likely links with socio-cultural environmental factors and existence of two type 2 subgroups. This profile underlines the challenges of screening, management and prevention of diabetes in Ivory Coast.

Malaria serology test seems to have attracted very little interest in endemic countries such as Ivory Coast. However, this examination has been regularly performed in the parasitology laboratory at the Training and Research Unit of Medical Sciences in Abidjan. Our study aimed to highlight the contribution of malaria serology test in our endemic country context. We conducted a retrospective study of malaria serology test using Falciparum-Spot IF (bioMerieux) kit for the detection of IgG antiplasmodial antibodies. It included all malaria serology tests performed from January 2007 to February 2011 and whose results were available in the registry. In total, 136 patients were selected. The average age of patients was 36,3 years, ranging from 1 to 81 years, and sex ratio was 0,97. Indications for malaria serology test were varied and dominated by splenomegaly (49.3%), cytopenias (14.7%), indeterminate fever (13.2%). Almost all of the patients (98.5%) had antiplasmodial antibodies with high medium titer of 1057,35IU/ml. There was no link between age and Ab titer, which was higher in cytopenias, prolonged fevers and the splenomegaly. Malaria serology test seems to have attracted very little interest in routine clinical practice provided in our endemic area because, whatever the reason of the prescription, titers were high.

The sensitive negative thermal ionization mass spectrometry method was used for the measurement of concentrations and isotopic ratios of osmium and rhenium in four Ivory Coast tektites. These tektites have crustal major and trace element composition, as well as large negative epsilon(sub Nd)(-20) and positive epsilon(sub Sr)(+260 to +300) which are characteristic for old continental crust. Os concentrations ranging from 0.09 to 0.30 ppb were found, clearly much higher than average crustal values, Os-187/Os-186 ratios of about 1.2-1.7, and low Re-187/Os-186 ratios. These results show unambiguously the existence of a meteoritic component (on the order of 0.06%) in the Ivory Coast tektites. Low Re abundances are the result of fractionation of Re during the impact.

Fungal infections of the scalp commonly affect the pediatric population. These infections are caused by dermatophytes that are able to invade the keratinized structures of skin, hair, and nails. This study aimed to analyze the epidemiology of fungal scalp infections in southern Ivory Coast during 2008-2009. From October 2008 to July 2009, 17,745 children ranging in age from 4-16 years, attending urban and rural primary schools in seven towns in Ivory Coast, were examined clinically for tinea capitis. Hair stumps and scales were collected from children who showed symptoms suggestive of scalp ringworm. Samples were exposed to direct microscopic examination using 30% potassium hydroxide solution and cultivation on Sabouraud's dextrose agar with or without actidione. Of the 17,745 children who were clinically examined, a total of 2645 exhibited symptoms suggestive of scalp ringworm. Positive cultures for fungi were found in 2458, yielding an overall prevalence of tinea capitis of 13.9%. The majority of infections occurred in males (74.0%). The most commonly affected age group involved children ranging from 9-12 years (n = 1335, 54.3%), followed by those in the range of 4-8 years (n = 936, 38.1%). Trichophyton soudanense, Microsporum langeronii, and Trichophyton mentagrophytes were the most prevalent etiologic agents (56.7%, 21.4% and 19.7%, respectively). Other species were occasionally isolated, including Trichophyton violaceum (1.4%) and Trichophyton rubrum (0.8%). Epidemiological surveys are an essential tool for developing strategies for infection control. © 2013 The International Society of Dermatology.
Infrasound from lightning measured in Ivory Coast
NASA Astrophysics Data System (ADS)
Farges, T.; Matoza, R. S.
2011-12-01
It is well established that more than 2,000 thunderstorms occur continuously around the world and that about 45 lightning flashes are produced per second over the globe. More than two thirds (42) of the infrasound stations of the International Monitoring System (IMS) of the CTBTO (Comprehensive nuclear Test Ban Treaty Organisation) are now certified and routinely measure signals due to natural activity (e.g., airflow over mountains, aurora, microbaroms, surf, volcanoes, severe weather including lightning flashes, ...). Some of the IMS stations are located where worldwide lightning detection networks (e.g. WWLLN) have a weak detection capability but lightning activity is high (e.g. Africa, South America). These infrasound stations are well localised to study lightning flash activity and its disparity, which is a good proxy for global warming. Progress in infrasound array data processing over the past ten years makes such lightning studies possible. For example, Farges and Blanc (2010) show clearly that it is possible to measure lightning infrasound from thunderstorms within a range of distances from the infrasound station. Infrasound from lightning can be detected when the thunderstorm is within about 75 km from the station. The motion of the squall zone is very well measured inside this zone. Up to 25% of lightning flashes can be detected with this technique, giving better results locally than worldwide lightning detection networks. An IMS infrasound station has been installed in Ivory Coast for 8 years. The optical space-based instrument OTD measured a rate of 10-20 flashes/km^2/year in that country and showed strong seasonal variations (Christian et al., 2003). Ivory Coast is therefore a good place to study infrasound data associated with lightning activity and its temporal variation. First statistical results will be presented in this paper based on 3 years of data (2005-2008).

Following the sociopolitical unrest that occurred in Ivory Coast in 2002, 360,000 Burkinabe immigrants returned to Burkina Faso that was the epicenter of sleeping sickness last century and is now thought to be free of autochthonous transmission. The purpose of this study was to determine if the massive return of immigrants from human African trypanosomiasis (HAT) endemic areas of Ivory Coast to areas in Burkina Faso where the vector (tsetse fly) is currently present could lead to re-emergence of the disease. Risk areas for re-emergence were identified taking into account the number of returning immigrants, history of the disease, and presence of tsetse flies. Based on these criteria, study was focused on two villages, i.e., Folonzo and Gbalara, located in southern Burkina Faso near the Ivory Coast border. Study in these two villages consisted of characterization of the population (repatriates or not, origin, ...) and medical surveys to assess the presence/absence of the disease. Departure of some returning immigrants from areas including sleeping sickness foci in Ivory Coast (e.g. center west) confirmed the potential risk of re-emergence of the disease. Although no case of sleeping sickness was diagnosed, several serologically positive people were identified and will be followed up. This study failed to demonstrate a clear-cut correlation between massive population movements due to war and reemergence of sleeping sickness. However, this study may have been timed too soon after the return of immigrants to detect reemergence of HAT that could require several years.

The tonalitic gneiss of Balmer (TGB), in the SASCA area of south-western Ivory Coast, previously dated at 3141 ± 2 Ma using the single zircon evaporation method, is regarded as a relic of Archean rock within the Paleoproterozoic (Birimian) formation of the West African Craton (WAC). We present new geochronological data for the TGB using the laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) method. We obtain a U-Pb age of 3207 ± 7 Ma for abundant zircons extracted from the tonalitic gneiss, and interpret this age as that of the magmatic protolith because of the igneous-type homogeneous zircon population. Certain magmatic zircon edges and some round zircons define an upper intercept age of 3155 ± 17 Ma which could represent overgrowths during gneissification. It appears that the TGB was not affected by the events posterior to its genesis, i.e. the Liberian (2.9-2.7 Ga) and Eburnean (2.4-2.0 Ga) events. Additionally, the TGB proves to be a juvenile Leonian rock, as indicated by the Nd model age of 3456 Ma, and could also constitute the protolith of the granulitic grey gneisses and charnockites of the Man area, which are 150-400 Ma younger.

Since a half of century, the forest surface area of the South Ivory Coast has been decreased for the benefit of agriculture (15 000 km2 in 1993 versus 83 000 km2 in 1955-1958). This area also undergoes climate change. Vegetation cover has gradually changed from rainforests (C3 plants) to savanna (C4 plants) and agricultural plants. In the Abidjan area (5.00-6.00°N, 2.40-4.40°W), the mean rainfall amount and temperature value evolve during the 20th century (1912 mm/year and 26.3°C/year during the first decennial to 1613 mm/year and 26.9°C/year during the last ten years). The Paleoproterozoïc fractured bedrock (PB) and the Continental Terminal (CT) deposits groundwater are studied to show the climate change and deforestation effect on the area groundwater resources using stable isotopes (18O, 2H and 13C) contents, radiocarbon (14C) contents and chemical data on a set of 25 groundwater samples. The residence time of the groundwaters is estimated by the 14C using two models: (i) the model of well-mixed reservoir (WMR model) and (ii) the piston flow model (PF model). The range of the PB groundwater residence time (15 000 - 8 000 to ~ 300 - 100 a BP) for both models shows that the recharge has started at the beginning of the post-glacial period whereas the CT aquifer recharge is much more recent (from 300 a BP to today). The PB groundwater provides information about paleoclimatic conditions that occurred over the studied area during the late Pleistocene. It is demonstrated, through this study, that the evolution of vegetation cover (from forests to savanna and agriculture plants) is shown in groundwater by the trend in 13C content from old groundwater (confined bedrock groundwater: residence time of ~ 15 000 a BP) to the recent groundwater (unconfined bedrock groundwater and CT groundwater: residence times: ~ 300 a BP and lower than 100 a BP, respectively). The δ18O and δ2H values also increase with time from the beginning of the post-glacial period (~ 15 000 a BP

French troops were sent to the Ivory Coast on September 22, 2002 within the framework of Operation Unicorn in response to the political unrest. From September 22 to October 20, a total of 37 cases of malaria were reported, i.e., 35.7 cases per 1000 man-months. As of October 11, the central headquarters of the Armed Services Health Corps decided to use doxycycline as the exclusive agent for drug prophylaxis in military personnel on duty in the Ivory Coast and to enhance vector control measures. The incidence of malaria decreased to 2 cases per 1000 man-months at the sixth month. A recrudescence of malaria to 15 cases per 1000 man-months was observed with the rainy season in April. During this period one person presenting severe malaria with coma required emergency evacuation to France. In May 2003, several studies were undertaken to determine the factors that caused this recrudescence. These studies included surveys to evaluate awareness concerning malaria and monitor compliance with drug prophylaxis and tolerance of doxycycline, a case-control study to identify factors related to malarious episodes and an entomological study. Awareness of malaria was high with 75% of the 477 respondents stating that malaria could be transmitted by single mosquito bite. The case-control study showed a correlation between occurrence of malarious bouts and non-compliance with drug prophylaxis (p < 10(-5)). The odds-ratio was 3.05 (95% confidence interval, 1.52-6.14) for subjects claiming zero to one incident of non-compliance per week and 7.51 (IC95%, 3.24-17.40) for those claiming more than one incident of non-compliance per week. Tolerance of doxycyline was good since 72% of respondents reported no adverse effects. The main vector was Anopheles gambiae. The number of bites per man per night ranged from 25 to 2 and the number of infected bites ranged from 2 to 3 per week. Treatment was initiated promptly using quinine at a total dose of 25 mg/kg in 3 daily doses for 7 days by the

With more than 6 million inhabitants, Abidjan district faces tremendous difficulties in water supply. The aquifer of the Continental Terminal which is actually the only drinking water source of the city shows a decline of resources and water demand is increasing due to the population growth. Moreover significant evidences of chemical and biological pollution of the groundwater are observed The Aghien lagoon, the largest freshwater pool located near Abidjan, has been identified by the State of Côte d'Ivoire as a potential resource for the production of drinking water.. The main objective of this project is to assess the quantitative and qualitative capacity of the Aghien lagoon to complement the water supply of Abidjan city in the near future. The main components of the project are: • to assess the water budget of the lagoon and its tributaries, • to characterize the spatial and temporal variability of contaminant levels and fluxes from the tributaries toward the lagoon, • to assess the sustainability of the water resources (quantity and quality) of the lagoon according to land use changes in the catchments . The project started in January 2015. The first year was devoted to the set-up of hydro-meteorological gauges within the lagoon watershed. Three major tributaries of the lagoon are considered, the Mé (4000 km2), the Djibi (78 km2) and Bete (206 km2) rivers. Since the start of the project, bi-monthly hydrochemical sampling surveys have been carried out along the tributaries and in the lagoon. The data available from the surveys concern the physico-chemical parameters, trace elements, all the forms of nitrogen and phosphorus, organic carbon, suspended solids. The Djibi and Bete watersheds are partly urbanized while the Mé basin is mainly rural. Baseflow has been identified as the major contribution to streamflow at the annual scale. The Mé flows into a channel downstream to the Aghien lagoon but during the floods, water from the Mé River can flow up the

While Female Genital Cutting (FGM/C) is a deeply entrenched cultural practice, there is now mounting evidence for a gradual decline in prevalence in a number of geographical areas in Africa and following migration to non-practicing countries. Consequently, there is now a growing number of women with FGM/C who are raising 'uncut' daughters. This study used a qualitative methodology to investigate the experience of women with FGM/C raising daughters who have not been subjected to the ritual. The aim of this study was to shed light on mothers' perception of the meaning and cultural significance of the practice and to gain insight into their mothering experience of 'uncut' girls. To this end, in-depth interviews were conducted with fifteen mothers living in Abidjan, Ivory Coast and in Montreal, Canada (8 and 7, respectively). Thirteen mothers intrinsically refused to perpetuate FGM/C onto their daughters and two diasporic mothers were in favour of FGM/C but forewent the practice for fear of legal repercussions. Whether the eschewing of FGM/C was deliberate or legally imposed, raising 'uncut' daughters had significant consequences in terms of women's mothering experiences. Mothers faced specific challenges pertaining to community and family pressure to have daughters undergo FGM/C, and expressed concerns regarding their daughters' sexuality. Conversely, women's narratives were also infused with pride and hope for their daughters, and revealed an accrued dialogue between the mother-daughter dyad about cultural norms and sexuality. Interestingly, women's mothering experience was also bolstered by the existence of informal networks of support between mothers with FGM/C whose daughters were 'uncut'. These communities of mothers engaged in open dialogue about the consequences of FGM/C and offered reciprocal solidarity and support in their decision to forego FGM/C for their children. Women with FGM/C who are raising 'uncut' daughters in their homeland and in their country of

It is well established that more than 2,000 thunderstorms occur continuously around the world and that about 45 lightning flashes are produced per second over the globe. More than two thirds (42) of the infrasound stations of the International Monitoring System (IMS) of the CTBTO (Comprehensive nuclear Test Ban Treaty Organisation) are now certified and routinely measure signals due to natural activity (e.g., airflow over mountains, aurora, microbaroms, surf, volcanoes, severe weather including lightning flashes, …). Some of the IMS stations are located where worldwide lightning detection networks (e.g. WWLLN) have a weak detection capability but lightning activity is high (e.g. Africa, South America). These infrasound stations are well localised to study lightning flash activity and its disparity, which is a good proxy for global warming. Progress in infrasound array data processing over the past ten years makes such lightning studies possible. For example, Farges and Blanc (2010) show clearly that it is possible to measure lightning infrasound from thunderstorms within a range of distances from the infrasound station. Infrasound from lightning can be detected when the thunderstorm is within about 75 km from the station. The motion of the squall zone is very well measured inside this zone. Up to 25% of lightning flashes can be detected with this technique, giving better results locally than worldwide lightning detection networks. An IMS infrasound station has been installed in Ivory Coast for 9 years. The lightning rate of this region is 10-20 flashes/km2/year from space-based instrument OTD (Christian et al., 2003). Ivory Coast is therefore a good place to study infrasound data associated with lightning activity and its temporal variation. First statistical results will be presented in this paper based on 4 years of data (2005-2009). For short lightning distances (less than 20 km), up to 60 % of lightning detected by WWLLN has been one-to-one correlated

The exotic tick Rhipicephalus (Boophilus) microplus was discovered in Ivory Coast in 2007 and then gradually in other countries in West Africa. It is known to induce significant losses in farming and to replace other species of the same genus. In order to contribute to improve health and productivity of cattle in Ivory Coast regarding the emergence of this dreaded tick, a study was conducted to determine the current geographic distribution of the tick R. (B.) microplus and review cattle ticks in general. To this end, 23,460 ticks were collected from 180 farms located throughout the country. Ten species of ticks belonging to the genus Rhipicephalus (including those of the subgenus Boophilus), Hyalomma and Ambyomma were identified. It was found that the exotic tick R. (B.) microplus has invaded the entire Ivorian territory and is now the main cattle tick (63.6% of ticks collected), followed by Amblyomma variegatum that remains still dominant in the North. The population of indigenous species of Rhipicephalus (Boophilus) is in drastic decline.

It is well established that more than 2,000 thunderstorms occur continuously around the world and that about 45 lightning flashes are produced per second over the globe. 80 % of the infrasound stations of the International Monitoring System (IMS) of the CTBTO (Comprehensive nuclear Test Ban Treaty Organisation) are now certified and routinely measure signals due to natural activity (e.g., airflow over mountains, aurora, microbaroms, surf, volcanoes, severe weather including lightning flashes …). Some of the IMS stations are located where lightning activity is high (e.g. Africa, South America). These infrasound stations are well localised to study lightning flash activity and its disparity, which is a good proxy for global warming. Progress in infrasound array data processing over the past ten years makes such lightning studies possible. Assink et al. (2008) and Farges and Blanc (2010) show clearly that it is possible to measure lightning infrasound from thunderstorms within 300 km. One-to-one correlation is possible when the thunderstorm is within about 75 km from the station. When the lightning flash occurs within 20 km, it is also possible to rebuild the 3D geometry of the discharges when the network size is less than 100 m (Arechiga et al., 2011; Gallin, 2014). An IMS infrasound station has been installed in Ivory Coast since 2002. The lightning rate of this region is 10-20 flashes/km²/year from space-based instrument OTD (Christian et al., 2003). Ivory Coast is therefore a good place to study infrasound data associated with lightning activity and its temporal variation. First statistical results will be presented in this paper based on 10 years of data (2005-2014). Correlation between infrasound having a mean frequency higher than 1 Hz and lightning flashes detected by the World Wide Lightning Location Network (WWLLN) is systematically looked for.

Thirteen clay samples from four deposits in the Ivory Coast (West Africa) were studied using X-ray diffraction, thermogravimetric analysis and chemical analysis. Mineralogical, crystallographic and morphological characteristics of these samples are given. Kaolinite is the principal mineral but other minerals are present in small quantities: illite, quartz, anatase and iron oxides (oxides and oxyhydroxides). The crystallographic, morphological and surface characteristics are influenced by the presence of these impurities. In particular, the presence of iron oxides was associated with reduced structural ordering and thermal stability of kaolinite and increased specific surface area. These clays could be used in the ceramics industry to make tiles and bricks, and also in agronomy as supports for chemical fertilizers or for environmental protection by immobilising potentially toxic waste products.

This article is a history of the field station Lamto, in Ivory Coast, which was created by French ecologists in 1962, after independence. It retraces the origins, the logics and the contradictions of an extraordinarily ambitious scientific project, which aimed at the systematic, holistic, quantitative and multi-disciplinary description of a unit of African nature - the savannah ecosystem. It explores how knowledge-making was articulated with work hierarchies and postcolonial politics, lifestyles, values and affects. It reconstitutes the political ecology of a research station in ecology, following in its residences, laboratories and open-air experiments the co-production of domesticity, nature, science and (post-)colonial situations.
Annual Movement Patterns of Endangered Ivory Gulls: The Importance of Sea Ice
Spencer, Nora C.; Gilchrist, H. Grant; Mallory, Mark L.
2014-01-01
The ivory gull (Pagophila eburnea) is an endangered seabird that spends its entire year in the Arctic environment. In the past three decades, threats from various sources have contributed to a >70% decline in Canada. To assess the annual habitat needs of this species, we attached satellite transmitters to 12 ivory gulls on Seymour Island, Nunavut in 2010, which provided up to four breeding seasons of tracking data. Analysis of migratory behaviour revealed considerable individual variation of post-breeding migratory route selection. Ivory gulls traveled a median of 74 days during post-breeding migration, but only 18 days during pre-breeding migration. In contrast to predictions, ivory gulls did not use the Greenland coast during migratory periods. Ivory gulls overwintered near the ice edge in Davis Strait, but also used the Labrador Sea in late February and March. We suggest that the timing of formation and recession and extent of sea ice plays a large role in ivory gull distribution and migratory timing. PMID:25551556

The aim of this study was to assess the biotope of the Cryptococcus neoformans/Cryptococcus gattii species complex from Ivory Coast, and clarify the possible epidemiological relationship between environmental and clinical strains. Samples from Eucalyptus camaldulensis (n=136), Mangifera indica (n=13) and pigeon droppings (n=518) were collected from different sites close to the living environment of Ivorian HIV patients with cryptococcosis (n=10, 50 clinical strains). Clinical and environmental strains were characterized by molecular serotyping and genotyping [RFLP analysis of the URA5 gene, (GACA)4, (GTG)5 and M13 PCR fingerprinting] and compared.Results/Key findings. Environmental strains were recovered only from the pigeon droppings. In vitro susceptibility profiles showed that all strains were susceptible to fluconazole, flucytosine and amphotericin B. All environmental strains consisted of C. neoformans (A, AFLP1/VNI), whereas clinical strains included C. neoformans (A, AFLP1/VNI), C. neoformans x Cryptococcus deneoformans hybrids (AD, AFLP3/VNIII) and Cryptococcus deuterogattii (B, AFLP6/VGII). Two patients were co-infected with both C. neoformans and C. neoformans x C. deneoformans hybrids. We noticed a low genetic diversity among the environmental samples compared to the high diversity of the clinical samples. Some clinical strains were genetically more similar to environmental strains than to other clinical strains, including those from the same patient. These results provide new information on the ecology and epidemiology of the C. neoformans/C. gattii species complex in Ivory Coast.

In the 1990s, defenders of "aids exceptionnalism" have promised that the inequities caused by HIV/AIDS could provide leverage in the care of other health issues later. Fifteen years later, this argument can be rethought at the light of the current context of hepatitis B virus (HBV) in Ivory Coast. In fact, in this country, the challenges caused by HBVecho those of HIV/AIDS fifteen years ago: high prevalence (8-10%), ignorance of the disease, and high cost of care. To this end, this article compares the role of private companies in the fights against HIV/AIDS in the 2000s and its role in the fight against HBV today. Although some private firms played a critical role in the promotion of universal access to ART, today, they are one of the few places where HBV screening, vaccination and treatment are offered in the country. HIV/AIDS opened the door for private companies to address other diseases through their health care systems. However, many challenges still need to be met: the absence of qualitative ongoing training for health professionals, illness representations and the costs of treatments, which are all related to the lack of international and national collective action. In Ivory Coast, at the early stage of the HIV/AIDS epidemic, national authorities took up the leadership in the fight against AIDS in West Africa, by developing extraverted strategies (Xth ICASA's organization, Unaids initiative hosting). The exceptional international mobilization and the creation of innovative funding mechanisms [International Therapeutic Solidarity Fund (ITSF), Global Fund (GM), and President's Emergency Plan for AIDS Relief (PEPFAR)] have facilitated easy access to ARV. Although 380 million people are infected by chronic HBV in the world, even so, international and national collective actions are fledgling and remained weak. Moreover, private firms have represented leverage for testing, treatment, and the provision of universal access to medication in the context of the HIV

Diseases always have a significant impact during military deployments. We evaluated the operational impact of health problems observed in a French infantry battalion (n = 690) during a 4-month assignment in Ivory Coast. In all, 55.7% of soldiers consulted at least once and sought care for 608 health problems. A total operational incapacity was observed in 22.2% of cases (7.6/1,000 person-days). The 5 diseases causing the greatest operational incapacity were diarrhea (2.1 days lost/1,000 person-days), musculoskeletal diseases and injuries (53.7 days), malaria (29 days), dental diseases (30.9 days), and fevers of undetermined origin (7 days). The incidence of diarrhea and skin infections was higher in rank-and-file troops than among noncommissioned officers. It was also higher during the mission's first month, when individual susceptibility to infections is suspected to be highest. Some diseases that are not serious nonetheless have a significant operational impact and should be better studied to determine preventive measures.
Dissecting the Illegal Ivory Trade: An Analysis of Ivory Seizures Data
Underwood, Fiona M.; Burn, Robert W.; Milliken, Tom

Reliable evidence of trends in the illegal ivory trade is important for informing decision making for elephants but it is difficult to obtain due to the covert nature of the trade. The Elephant Trade Information System, a global database of reported seizures of illegal ivory, holds the only extensive information on illicit trade available. However inherent biases in seizure data make it difficult to infer trends; countries differ in their ability to make and report seizures and these differences cannot be directly measured. We developed a new modelling framework to provide quantitative evidence on trends in the illegal ivory trade from seizures data. The framework used Bayesian hierarchical latent variable models to reduce bias in seizures data by identifying proxy variables that describe the variability in seizure and reporting rates between countries and over time. Models produced bias-adjusted smoothed estimates of relative trends in illegal ivory activity for raw and worked ivory in three weight classes. Activity is represented by two indicators describing the number of illegal ivory transactions – Transactions Index – and the total weight of illegal ivory transactions – Weights Index – at global, regional or national levels. Globally, activity was found to be rapidly increasing and at its highest level for 16 years, more than doubling from 2007 to 2011 and tripling from 1998 to 2011. Over 70% of the Transactions Index is from shipments of worked ivory weighing less than 10 kg and the rapid increase since 2007 is mainly due to increased consumption in China. Over 70% of the Weights Index is from shipments of raw ivory weighing at least 100 kg mainly moving from Central and East Africa to Southeast and East Asia. The results tie together recent findings on trends in poaching rates, declining populations and consumption and provide detailed evidence to inform international decision making on elephants.

Globally, activity was found to be rapidly increasing and at its highest level for 16 years, more than doubling from 2007 to 2011 and tripling from 1998 to 2011. Over 70% of the Transactions Index is from shipments of worked ivory weighing less than 10 kg and the rapid increase since 2007 is mainly due to increased consumption in China. Over 70% of the Weights Index is from shipments of raw ivory weighing at least 100 kg mainly moving from Central and East Africa to Southeast and East Asia. The results tie together recent findings on trends in poaching rates, declining populations and consumption and provide detailed evidence to inform international decision making on elephants.

Vavoua human trypanosomiasis focus, located 60 km north of Daloa (Ivory Coast Republic) is facing a period of hyperactivity. A medical survey has been conducted in 9 villages of this focus: 7.424 persons have been examined and 128 new cases diagnosed in the field after clinical and parasitological examinations. Indirect Fluorescence Antibody Test applied to dried blood blots, in the laboratory, revealed 266 immunological suspects to be reexamined. 185 suspects were reexamined, 104 of whom were diagnosed after tyrpanosomes had been found in blood or/and in gland juice. The microhaematocrit centrifuge technique gave good results. Most of the 232 new cases were in the classical first period (unaltered CSF). Authors are insisting on the importance of survey prospections allowing an early diagnosis of sleeping sickness and on the interest of an immunodiagnostic test in addition to classical techniques to diagnose asymptomatical forms.

In Ivory Coast, little is known about health needs and health access barriers among young people. The aim of this study was to describe health provision, health needs and barriers when seeking medical care, with an emphasis on sexual and reproductive health, and the acceptability of a medical examination for students attending their first year at the Houphouët-Boigny University, Abidjan, Ivory Coast. We conducted a representative cross-sectional study among second year students who were selected by two-stage equiprobable random sampling. In-depth interviews were conducted among students and the university health center staff. Five hundred and forty three students (322 men and 221 women) answered a questionnaire (participation rate 98.4%). Among women who ever had sex, 38.4% (95%CI [30.5%-47.0%]) had unmet contraception needs and 31.2% [23.7%-40.0%] had experienced an unwanted pregnancy. Fear about impaired fertility was the leading reason for non-use of hormonal contraception, the method of choice among most students. The main health problems among students, by order of frequency were malaria (54.3%), respiratory infection (44.6%), constipation (28.0%) and psychological problems (25.9%). High cost perception of services offered, despite their gratuity, were the main barriers against access to the university health center, indicating a lack of communication about this structure and its services. The majority of students favored the establishment of a medical examination during the first year at the university. Establishing a medical examination would improve health center visibility. The following services could be offered: (i) HIV, chlamydia and gonorrhea screening, (ii) hepatitis B virus screening and vaccination, (iii) provision and information about contraceptive methods, (iv) presentation of the university health center services. Dedicated spaces where students could have access to information about health-related topics (e.g. sexuality, nutrition, depression
Can We Sustainably Harvest Ivory?
Lusseau, David; Lee, Phyllis C
2016-11-07
Despite the 1989 ivory trade ban, elephants continue to be killed to harvest their tusks for ivory. Since 2008, this poaching has increased to unprecedented levels driven by consumer demand for ivory products. CITES is now considering the development of a legal ivory trade [1, 2]. The proposal relies on three assumptions: (1) harvest regulation will cease all illegal activities, (2) defined sustainable quotas can be enforced, and (3) we can define meaningful sustainable quotas that come close to the current demand. We know that regulation of harvest does not stop illegal takes. Despite whaling regulation after World War II, illegal whaling continued for decades [3]. The introduction of wolf culls in the US actually increased poaching activities [4], and one-off ivory sales in 1999 and 2008 did nothing to halt elephant poaching. Governance issues over the ivory supply chains, including stockpiling, make enforcing quotas challenging, if not impossible [5, 6]. We have not yet adequately assessed what could be a sustainable ivory yield. To do so, we develop a compartmental model composed of a two-sex age-structured demographic model and an ivory production and harvest model. We applied several offtake and quota strategies to define how much ivory could be sustainably harvested. We found that the sustainability space is very small. Only 100 to 150 kg of ivory could be removed from a reference population of 1,360 elephants, levels well below the current demand. Our study shows that lifting the ivory ban will not address the current poaching challenge. We should instead focus on reducing consumer demand. Copyright © 2016 Elsevier Ltd. All rights reserved.

The benthic macroinvertebrates of Aby lagoon (West Africa: Ivory coast) was studied during four seasons (high dry season, high rainy season, low dry season and low rainy season, respectively) from June 2006 to March 2007. The distribution of the benthic macroinvertebrates species was recorded at 13 stations on the whole of the lagoon. A total of 62 taxa of benthic macroinvertebrates belonging to 28 families and 10 orders were listed. The molluscs and crustaceans dominate qualitatively by adding up 51 and 24%, respectively of the total number of organisms. Five taxa (Corbula trigona (20%), Pachymelania aurita (12%), Clibernhardius cooki (7%), Oligochaeta (7%) and Crassostrea gasar (6%) accounted for 52% of total abundance. Classification analysis used to perform the characterisation of the lagoon on the basis of benthic macroinvertebrates showed the existence of four main clusters in which the seasonal pattern in benthic macroinvertebrates were very similar in the four seasons. In contrast the species richness and diversity indices were significantly different. Furthermore these indices where higher in the stations closer to the sea and surrounded by mangrove trees (southern area) compared to the inland ones.

Smoking promotes, among other health problems, the development of tuberculosis and the discovery of a case of tuberculosis can therefore be an opportunity for tobacco control interventions. We conducted a prospective study evaluating the knowledge of 37 Ivorian physicians (32 men and 5 women with 5 active smokers) on the relationship between smoking and tuberculosis and their attitudes to smoking tuberculous patients between February and August 2012 using an anonymous self-administered questionnaire. The response rate to the questionnaire was 88.1%. Among them, 70.3% of Ivorian physicians knew that smoking increased the incidence of tuberculosis, 75.7% said that forms of tuberculosis were more severe in smokers and about 27% thought that the cure rate of tuberculosis was lower in smokers. No significant difference was observed according to respondents' smoking status, or gender. Patients' smoking status was always assessed by 64.9% of physicians and by 78.4% in patients with tuberculosis, again not differing by physicians' smoking status or gender. The risks of smoking were always explained to patients with active pulmonary tuberculosis by 43.2% and benefits of stopping smoking ware always described in 35.1%. An intervention for smoking cessation was systematically offered to smokers having tuberculosis by 59.4% of physicians and 8.1% offered medication for smoking cessation. These results strongly support the need to reinforce physician behaviors to address smoking in patients with tuberculosis in Ivory Coast. Copyright © 2014 SPLF. Published by Elsevier Masson SAS.

The District of Abidjan, located on the coastal sedimentary basin south of Côte d'Ivoire (West Africa) covers an area of 2,1 km2. This sedimentary basin is composed of continuous groundwater aquifers in Quaternary, Tertiary and Upper Cretaceous rocks. Our study focuses on the unconfined Quaternary groundwater called the Continental Terminal which formations are composed mainly of lenticular stratification of coarse sands, clays, ferruginous sandstone and iron ore. This Continental Terminal aquifer is the main source of drinking water for the city of Abidjan. Indeed, the city of Abidjan is facing various pollution problems such as illegal dumping of household waste, waste oils garages, domestic and industrial wastewater, gas stations, public discharge Akouédo and the spill of approximately 500 tons of toxic waste from the ship "Probo Koala" the night of 19 August 2006. These toxic wastes have killed more than 10 people and several infections. The infiltration of these contaminants under the influence of rainwater in the basement is a serious threat to groundwater from the District of Abidjan especially as the rains are very strong in this part of the country. What would be the fate of pollutants such as organochlorines, hydrogen sulfide, sulfides and hydrocarbons contained in toxic waste, knowing that this aquifer is the main source of supply of drinking water to the city of Abidjan? It therefore seems necessary to study the vulnerability of groundwater of Abidjan District. The overall objective of this study is to assess the risk of groundwater contamination by organochlorines, sulfides, hydrogen sulfide and hydrocarbons. This project is to develop groundwater flow and contaminant transport models such as organochlorines models, hydrogen sulfide and sulfides with two digital codes, Visual Modflow and Feflow. Then several scenarios with different pollutants are finally made to realize maps of groundwater vulnerability from Abidjan to these contaminants.

The age determination of elephant ivory provides necessary and crucial information for all criminal prosecution authorities enforcing the Convention on International Trade in Endangered Species of Wild Fauna and Flora. The knowledge of the age of ivory allows to distinguish between pre-convention, hence legal material and ivory deriving from recent, illegal poaching incidents. The commonly applied method to determine the age of ivory is radiocarbon dating in the form of bomb pulse dating, which however will fade out soon. This work provides an enhancement of the radiocarbon dating method by supplementary determination of the isotope profile of 90-Sr and the two thorium isotopes 228-Th and 232-Th. This combined analysis allows for a precise and unambiguous age determination of ivory. We provided calibration curves for all involved radionuclides by analyzing ivory samples with known age and investigated a new method for the extraction of strontium from ivory.

Yellow fever remains one of the great burdens for public health in the endemic regions in Africa and South America. The under reporting of yellow fever cases in the respective regions and lack of international interest leads to an underestimation of the constant danger in these areas. Non-vaccinated travelers take a high risk without the effective protection of YFV 17D vaccination. Two YF cases were imported to Europe in the last 4 years. We characterized two yellow fever virus (YFV) isolates from severely infected patients coming back from Africa, Ivory Coast and The Gambia, by genome sequencing and phylogenetic analysis. The virus infections in different organs were analyzed with pathological, immunohistological, electronmicroscopical and quantitative real-time PCR methods. High virus loads in spleen and liver (2.4 x 10 (6) to 3 x 10 (7)GE/mL) demonstrated by real time PCR show massive virus replication leading to extraordinary progression of the disease in these patients. Immunohistological and electronmicroscopical analysis confirms virus particles in liver tissue. In all other organs no virus could be detected. A fast, specific and sensitive virus PCR detection is recommended for diagnostic of acute infections. The further sequence alignments show that the new isolates belong to the type II West African strain with great homology to over 40-year old YF isolates from Senegal and Ghana. The divergence observed was on average 3.3%, ranging from 0.0% to 5.0% in the coding region of Gambia 2001 strain and 2.9 %, ranging from 0.0% to 4.3% in the coding region of the Ivory C 1999 strain. Most mutations (5.0%/4.3%, respectively) occurred in the envelope protein.

Objectives To assess antibiotic susceptibility of community-acquired respiratory tract isolates from Ivory Coast, Kenya, Democratic Republic of Congo (DRC) and Senegal in 2011–14. Methods Bacterial isolates were collected and MICs determined using Etest® for all antibiotics except erythromycin, for which testing was by disc diffusion. Susceptibility was assessed using CLSI, EUCAST and pharmacokinetic/pharmacodynamic (PK/PD) breakpoints. For macrolide interpretation, CLSI breakpoints were adjusted for incubation in CO2. Results Susceptibility to penicillin (using CLSI oral or EUCAST breakpoints) was low among isolates of Streptococcus pneumoniae from the DRC and Kenya (17.4% and 19%, respectively) but higher among isolates from the Ivory Coast (70%) and Senegal (85.7%). Penicillin susceptibility using CLSI iv breakpoints was higher in all countries, but still only 69.6% in the DRC. Macrolide susceptibility (based on CLSI erythromycin disc diffusion breakpoints) was also low in Kenya (∼65%) but 87%–100% elsewhere. Haemophilus influenzae were only collected in the DRC and Senegal, with β-lactamase prevalence of 39% and 4%, respectively. Furthermore, β-lactamase-negative ampicillin-resistant (BLNAR) isolates were found in DRC (four isolates, 17%), but only two isolates were found in Senegal (by EUCAST definition). Amoxicillin/clavulanic acid in vitro susceptibility was 73.9% in the DRC and 100% in Senegal based on CLSI breakpoints, but this reduced to 65.2% in the DRC when BLNAR rates were considered. Clarithromycin susceptibility was >95% in both countries. Conclusions There was considerable variability in antibiotic susceptibility among the African countries participating in the surveillance programme. Thus, continued surveillance is necessary to track future changes in antibiotic resistance. Use of EUCAST versus CLSI breakpoints showed profound differences for cefaclor and ofloxacin against S. pneumoniae, with EUCAST showing lower susceptibility. PMID

Recent increases in ivory poaching have depressed African elephant populations. Successful enforcement has led to ivory stockpiling. Stockpile destruction is becoming increasingly popular, and most destruction has occurred in the last 5 years. Ivory destruction is intended to send a strong message against ivory consumption, both in promoting a taboo on ivory use and catalyzing policy change. However, there has been no effort to establish the distribution and extent of media reporting on ivory destruction events globally. We analyzed media coverage of the largest ivory destruction event in history (Kenya, 30 April 2016) across 11 nation states connected to ivory trade. We used an online-media crawling tool to search online media outlets and subjected 5 of the largest print newspapers (by circulation) in 5 nations of interest to content analysis. Most online news on the ivory burn came from the United States (81% of 1944 articles), whereas most of the print news articles came from Kenya (61% of 157 articles). Eighty-six to 97% of all online articles reported the burn as a positive conservation action, whereas 4-50% discussed ivory burning as having a negative impact on elephant conservation. Most articles discussed law enforcement and trade bans as effective for elephant conservation. There was more relative search interest globally in the 2016 Kenyan ivory burn than any other burn in 5 years. Ours is the first attempt to track the reach of media coverage relative to an ivory burn and provides a case study in tracking the effects of a conservation-marketing event. © 2018 Society for Conservation Biology.

An intergenic region V Mitochondrial DNA (mtDNA) 9 bp deletion located between the genes for tRNA{sup LYS} and cytochrome oxidase II was discovered in a small percentage of Nigerian and Ivory Coast natives. Previously this deletion has been described as Asian-specific and has been reported throughout the New World, Asia, S.E. Asia, and the Pacific Islands at frequencies ranging from 0% to 100%. In the New World and the Pacific Islands, the deletion is almost always accompanied by an Hae III restriction site gain at nt 16517. All 9 occurrences of the deletion observed in Africa (from four different populations)more » co-occur with the Hae III 16517 site gain, indicating that the African deletion probably shares a common origin with the deletion described as {open_quotes}Asian-specific{close_quotes}. The deletion was found in Benin and Sokoto, Nigeria in 2/54 Edo Bini, 1/2 Edo Ishan, 3/99 Hausa, 0/18 Fulani, and 0/16 other Nigerians. The deletion was also detected in 3/115 Ivory Coast natives from Abidjan. A 9 bp insertion (triplication) was observed in 1/115 Ivory Coast natives. The triplicated individual also possessed the Hae III 16517 site gain. The fragment containing the African deletion was sequenced and found to be identical in sequence to the Asian deletion region. D-loop sequence of nts 15975 to 00048 revealed that 2 of the 3 Ivory Coast deleted individuals and 1 of the 6 Nigerians deleted (Hausa) had a T-C transition at nt position 16189 which is common in New World-deleted individuals. These results raise the possibility that the occurrence of this deletion predates the separation of Asian and African populations from a common ancestral populations, or that the deletion has occurred more than once in human evolution. Either explanation requires that caution be exercised when using the 9 bp deletion as a population marker.« less
Geographic variation of stable isotopes in African elephant ivory

In 1989, the international community listed the African elephant in Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) thus prohibiting commercial ivory trade. Recent surveillance data show that the illegal trade in ivory has been growing worldwide. Long-term preservation of many of the African elephant populations can be supported with a control mechanism that helps with the implementation of remedial conservation action. Therefore, setting up a reference database that predicts the origin of ivory specimens can assist in determining smuggling routes and the provenance of illegal ivory. Our research builds on earlier work to seek an appropriate method for determining the area of origin for individual tusks. Several researchers have shown that the provenance of elephant ivory can be traced by its isotopic composition, but this is the first attempt to produce an integrated isotopic reference database of elephant ivory provenance. We applied a combination of various routine geochemical analyses to measure the stable isotope ratios of hydrogen, carbon, nitrogen, oxygen, and sulphur. Up to now, we analysed 606 ivory samples of known geographical origin from African range states, museums and private collections, comprising 22 African elephant range states. The isotopic measurements were superimposed with data layers from vegetation, geology and climate. A regression function for the isotope composition of the water isotopes in precipitation and collagen in ivory was developed to overcome the problem of imprecise origin of some of the sampled material. Multivariate statistics, such as nearest neighborhood and discriminate analysis were applied to eventually allow a statistical determination of the provenance for ivory of unknown origin. Our results suggest that the combination of isotopic parameters have the potential to provide predictable and complementary markers for estimating the origin of seized elephant ivory.

The objective of this study was to document the influence of pornography on the sexual behaviour of school children in the Cocody district of Abidjan, Cote d'Ivoire. This cross-sectional, descriptive and analytical study was conducted from October to November 2013 with pupils from four schools in Cocody, Abidjan. A total of 398 pupils (224 boys and 174 girls) were interviewed: 14.3% of them had access to pornography on internet or television. 52.8% (210) of the 398 pupils interviewed were sexually active at the time of the survey, 41.9% (88/210) of whom had at least two sexual partners. On bivariate analysis,access to pornography was statistically associated with being sexually active (OR= 2.61; 95%CI [1.41; 4.83]), early onset of sexual intercourse (OR= 2.38; 95%CI = [1.19; 4.76]) and multiples exual partners (OR== 6.09; 95%CI= [2.79; 13.3])Conclusion: The results of this study demonstrate that access to pornography had a negative influence on the sexual behaviour of school children in Abidjan (Côte d'Ivoire].

Chrysophyllum perpulchrum (Sapotaceae) is used in the traditional Ivory Coast pharmacopeia to cure fevers. The extract of C. perpulchrum used for this study was the powdered form obtained from the maceration of the dried plant bark in 96% methanol, followed by evaporation to dryness. In the present study, the antioxidative and radical-scavenging activities of the methanolic extract were studied with three standard biological tests: DPPH reduction, ferric thiocyanate (FTC) lipidic peroxidation inhibition and thiobarbituric acid reacting substances (TBARS). Gallic acid and quercetin were used as references. The total amount of phenolic compounds in the extract was determined by ultraviolet (UV) spectrometry and calculated as gallic acid equivalents. Catechin and two dimeric procyanidins were found to be the compounds responsible for the activities. They were chemically dereplicated in the extract by LC-MS. For quantitation purposes, they were isolated by successive chromatographic methods and characterized by mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectrometry. The quantities of these compounds in C. perpulchrum were 5.4% for catechin (P1), and 5.6 and 9.2% for dimers (compounds 2 (P2) and 3 (P3)), respectively. They displayed antioxidant activity with IC(50) values of 2.50 ± 0.15 µg/mL (P1), 2.10 ± 0.2 µg/mL (P2) and 2.10 ± 0.1 µg/mL (P3). The total extract, the active fractions and the pure compounds inhibited the lipid peroxidation by the FTC method and the TBARS method in the range of 60%. These values were comparable to those seen for quercetin.

Illegal trading of ivory is mainly responsible for the dramatic decline in elephant populations. Thailand is one of the largest laundering hotspots for African ivory, as the domestic Asian elephant ivory can be legally traded. So, to help combat ivory poaching and smuggling, an efficient method is needed to identify the elephant species from its ivory and ivory products. In this study, a mini-SNaPshot ® multiplex assay was developed and fully validated for the identification of confiscated ivory and low DNA template ivory products. Elephantid- and elephant species-specific mitochondrial single nucleotide polymorphisms (SNPs) were identified from 207 mammalian and 1705 elephant/mammoth cytochrome b sequence alignments. Seven informative SNPs were used for assay development. The assay unambiguously and accurately identified authentic elephant ivory and its species of origin on the basis of peak size and color observed in the haplotype profile. The assay was highly efficient for analysis of confiscated ivory and low-template ivory products with a 99.29% success rate (N=140). It was highly reproducible, exhibited no cross-reaction with eight other mammalian DNA; and had 100% identification accuracy. In addition, nested and direct PCR amplification were also compatible with the developed assay. This efficient assay should benefit wildlife forensic laboratories and aid in the prosecution of elephant-related crimes. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The DACCIWA (Dynamics-Aerosol-Chemistry-Cloud Interactions over West Africa) airborne field campaign was conducted in Southern West Africa in June/July 2016. Three European research aircraft (DLR - Falcon 20, SAFIRE - ATR 42 and BAS - Twin Otter) were deployed from Lomé/Togo and conducted research flights across Ivory Coast, Ghana, Togo and Benin. On board the DLR Falcon O3, SO2, CO, NO2 and aerosol fine mode particle number concentration and size distribution were measured during a total of 12 scientific flights. Until now only few airborne trace gas measurements were conducted in Southern West Africa. Therefore, this field experiment contributes to the knowledge of the chemical composition of the lower troposphere between 0 - 4 km. During several flights pollution plumes from major population centers - Lomé/Togo, Accra/Ghana, Kumasi/Ghana, and Abidjan/Ivory Coast - were probed below, inside and above clouds. Here, enhanced trace gas and particle concentrations were observed. In addition, plumes from biomass burning emissions were detected which were transported to West Africa. The composition of the pollution plumes are presented as well as transport pathways using HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectories) trajectory calculations. Ozone enhancements in the biomass burning pollution plumes of up to 70 ppb were observed compared to background concentrations of 30-40 ppb. Furthermore, HYSPLIT atmospheric dispersion simulations are used to estimate anthropogenic SO2 city emissions.

Microbial fermentation is an indispensable process for high quality chocolate from cocoa bean raw material. lactic acid bacteria (LAB) are among the major microorganisms responsible for cocoa fermentation but their exact role remains to be elucidated. In this study, we analyzed the diversity of LAB in six cocoa producing regions of Ivory Coast. Ribosomal 16S gene sequence analysis showed that Lactobacillus plantarum and Leuconostoc mesenteroides are the dominant LAB species in these six regions. In addition, other species were identified as the minor microbial population, namely Lactobacillus curieae, Enterococcus faecium, Fructobacillus pseudoficulneus, Lactobacillus casei, Weissella paramesenteroides and Weissella cibaria. However, in each region, the LAB microbial population was composed of a restricted number of species (maximum 5 species), which varied between the different regions. LAB implication in the breakdown of citric acid was investigated as a fundamental property for a successful cocoa fermentation process. High citrate lyase producer strains were characterized by rapid citric acid consumption, as revealed by a 4-fold decrease in citric acid concentration in the growth medium within 12h, concomitant with an increase in acetic acid and lactic acid concentration. The production of citrate lyase was strongly dependent on environmental conditions, with optimum production at acidic pH (pH<5), and moderate temperature (30-40°C), which corresponds to conditions prevailing in the early stage of natural cocoa fermentation. This study reveals that one of the major roles of LAB in the cocoa fermentation process involves the breakdown of citric acid during the early stage of cocoa fermentation through the activity of citrate lyase.

Despite continuous conservation efforts by national and international organizations, the populations of the three extant elephant species are still dramatically declining due to the illegal trade in ivory leading to the killing of elephants. A requirement to aid investigations and prosecutions is the accurate identification of the elephant species from which the ivory was removed. We report on the development of the first fully validated multiplex PCR-electrophoresis assay for ivory DNA analysis that can be used as a screening or confirmatory test. SNPs from the NADH dehydrogenase 5 and cytochrome b gene loci were identified and used in the development of the assay. The three extant elephant species could be identified based on three peaks/bands. Elephas maximus exhibited two distinct PCR fragments at approximate 129 and 381 bp; Loxodonta cyclotis showed two PCR fragments at 89 and 129 bp; and Loxodonta africana showed a single fragment of 129 bp. The assay correctly identified the elephant species using all 113 ivory and blood samples used in this report. We also report on the high sensitivity and specificity of the assay. All single-blinded samples were correctly classified, which demonstrated the assay's ability to be used for real casework. In addition, the assay could be used in conjunction with the technique of direct amplification. We propose that the test will benefit wildlife forensic laboratories and aid in the transition to the criminal justice system. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
Mapping the Elephants of the 19th Century East African Ivory Trade with a Multi-Isotope Approach
Lee-Thorp, Julia; Collins, Matthew J.; Lane, Paul J.

East African elephants have been hunted for their ivory for millennia but the nineteenth century witnessed strongly escalating demand from Europe and North America. It has been suggested that one consequence was that by the 1880s elephant herds along the coast had become scarce, and to meet demand, trade caravans trekked farther into interior regions of East Africa, extending the extraction frontier. The steady decimation of elephant populations coupled with the extension of trade networks have also been claimed to have triggered significant ecological and socio-economic changes that left lasting legacies across the region. To explore the feasibility of using an isotopic approach to uncover a ‘moving frontier’ of elephant extraction, we constructed a baseline isotope data set (δ13C, δ15N, δ18O and 87Sr/86Sr) for historic East African elephants known to have come from three distinct regions (coastal, Rift Valley, and inland Lakes). Using the isotope results with other climate data and geographical mapping tools, it was possible to characterise elephants from different habitats across the region. This baseline data set was then used to provenance elephant ivory of unknown geographical provenance that was exported from East Africa during the late nineteenth and early twentieth centuries to determine its likely origin. This produced a better understanding of historic elephant geography in the region, and the data have the potential to be used to provenance older archaeological ivories, and to inform contemporary elephant conservation strategies.

East African elephants have been hunted for their ivory for millennia but the nineteenth century witnessed strongly escalating demand from Europe and North America. It has been suggested that one consequence was that by the 1880s elephant herds along the coast had become scarce, and to meet demand, trade caravans trekked farther into interior regions of East Africa, extending the extraction frontier. The steady decimation of elephant populations coupled with the extension of trade networks have also been claimed to have triggered significant ecological and socio-economic changes that left lasting legacies across the region. To explore the feasibility of using an isotopic approach to uncover a 'moving frontier' of elephant extraction, we constructed a baseline isotope data set (δ13C, δ15N, δ18O and 87Sr/86Sr) for historic East African elephants known to have come from three distinct regions (coastal, Rift Valley, and inland Lakes). Using the isotope results with other climate data and geographical mapping tools, it was possible to characterise elephants from different habitats across the region. This baseline data set was then used to provenance elephant ivory of unknown geographical provenance that was exported from East Africa during the late nineteenth and early twentieth centuries to determine its likely origin. This produced a better understanding of historic elephant geography in the region, and the data have the potential to be used to provenance older archaeological ivories, and to inform contemporary elephant conservation strategies.

The corollary of the concept of the "ivory tower", as reflected in the writings of Plato and Newman amongst others, was, paradoxically, the vital importance of the university for wider society. Nevertheless from the mid-twentieth century, the esteem in which a "liberal" university education was held was diminished by rising…

Among the earliest Homo sapiens societies in Eurasia, the Aurignacian phase of the Early Upper Paleolithic, approximately 40 000-30 000 years ago, mammoth ivory assumed great social and economic significance, and was used to create hundreds of personal ornaments as well as the earliest known works of three-dimensional figurative art in the world. This paper reports on the results of micro-PIXE/PIGE analyses of mammoth-ivory artifacts and debris from five major sites of Aurignacian ivory use. Patterns of variable fluorine content indicate regionally distinctive strategies of ivory procurement that correspond to apparent differences in human-mammoth interactions. Preserved trace elements (Br, Sr, Zn) indicate that differences at the regional level are applicable to sourcing Paleolithic ivory at the regional scale. © 2018 Wiley-VCH Verlag GmbH & Co.

The sacroiliac joint remains unknown in sub-Saharan Africa. Studies about the sacroiliac diseases are rare Aim : Describe the epidemiological, clinical, radiological and etiological characteristics of sacroiliac joint diseases in Abidjan Methods : Retrospective and descriptive study concerning 17 patients hospitalized from February 2003 to April 2010 in the department of rheumatology of university hospital center of Cocody (Abidjan) for buttock pain or others functional signs evoking sacroiliac joint which were attested by radiographic lesions. We were interested on the epidemiological, clinical and radiological characteristics and the etiologies in the sacroiliac disease. The hospital prevalence of sacroiliac diseases was 0.55% corresponding in 17 of 3067 rheumatological diseases. The female sex predominated (82.35%) and the mean age of 25.58 years. Gyneco-obstetric events were the predominant risk factors (47.05%). Sacroiliac damage was manifested by inflammatory pain (64.7%) localized at the buttock or lumbar spine, radiating to the thigh (52.9%) and was accompanied by functional disability (82.2%) and fever was not present every time (64.7%). The physical findings were the tripod sign positive (58.8%), the monopodal backing positive (41.2%) and palpation painful of sacroiliac joint. The standard radiograph revealed a blurring aspect and widening of joint space associated with demineralization (68.4%), a joint space narrowing and erosion of articular banks (23.5%). The etiologies found were bacterial arthritis (82.3%) mainly pyogenic (70.58%), osteoarthritis (11.7%) and ankylosing spondylitis (5.9%). Sacroiliac joint diseases are rare in rheumatology practice in Abidjan, concern younger subjects and are dominated by pyogenic sacroiliitis.

The serological HPV status of 35 patients with SCA (Hb SS), randomly chosen from a sickle cell clinic in rural south-west Togo and of 13 household members with normal haemoglobin type (Hb AA) was assessed. No difference in HPV-IgG seropositivity rate was found. In 30 urban hospital patients from Abidjan, Ivory Coast, who were in acute painful sickle cell crisis HPV-IgG seropositivity rate increased with age. In only one (HIV positive) patient HPV-IgM antibodies were detected. It is concluded that HPV-infection exists in West Africa (1) and that there is no evidence for increased seroprevalence in SCA (2). HPV does not seem to trigger acute painful crises in SCA (3). The age-specific HPV seropositivity increase in urban patients may be due to differing transmission rates in urban and rural areas.

From March to December 2001, an outbreak of yellow fever was observed in Cote d'Ivoire. Sentinel surveillance for hemorrhagic fever allowed detection of the first case in the Duekoue health district in the heavily wooded western part of the country. A weekly reporting system was established. For each suspected case recorded and reported to the Epidemiological Surveillance Department at the National Institute of Public Hygiene, a sample was collected and sent for confirmation at the Pasteur Institute of the Cote d'Ivoire. The outbreak progressed from West to East reaching Abidjan, the economic capital of the country located in the southeast. The epidemic emergency plan consisted of setting up a crisis committee to implement epidemiological, entomological and virological surveillance, mass vaccination campaigns in areas around confirmed cases, and vector control. A total of 280 cases were reported including 32 confirmed cases and 6 deaths. Eleven out of 62 districts were affected with most cases occurring in cities with more than 10000 inhabitants. Over 3.7 million persons were vaccinated for an overall coverage of 92.2% in the areas where campaigns were carried out. As a result of this outbreak, surveillance for potentially epidemic diseases has been reinforced and surveillance of viral transmission is now being considered. A vaccination program for adults has also been established.
Legal ivory trade in a corrupt world and its impact on African elephant populations.
Bennett, Elizabeth L
2015-02-01
Illegal hunting of African elephants (Loxodonta africana) for ivory is causing rapid declines in their populations. Since 2007, illegal ivory trade has more than doubled. African elephants are facing the most serious conservation crisis since 1989, when international trade was banned. One solution proposed is establishment of a controlled legal trade in ivory. High prices for ivory mean that the incentives to obtain large quantities are high, but the quantity of tusks available for trade are biologically constrained. Within that context, effective management of a legal ivory trade would require robust systems to be in place to ensure that ivory from illegally killed elephants cannot be laundered into a legal market. At present, that is not feasible due to corruption among government officials charged with implementing wildlife-related legislation. With organized criminal enterprises involved along the whole commodity chain, corruption enables the laundering of illegal ivory into legal or potentially legal markets. Poachers and traffickers can rapidly pay their way out of trouble, so the financial incentives to break the law heavily outweigh those of abiding by it. Maintaining reliable permitting systems and leak-proof chains of custody in this context is challenging, and effective management breaks down. Once illegal ivory has entered the legal trade, it is difficult or impossible for enforcement officers to know what is legal and illegal. Addressing corruption throughout a trade network that permeates countries across the globe will take decades, if it can ever be achieved. That will be too late for wild African elephants at current rates of loss. If we are to conserve remaining wild populations, we must close all markets because, under current levels of corruption, they cannot be controlled in a way that does not provide opportunities for illegal ivory being laundered into legal markets. © 2014 Society for Conservation Biology.

Carbon-14 measurements on 231 elephant ivory specimens from 14 large ivory seizures (≥0.5 ton) made between 2002 and 2014 show that most ivory (ca. 90%) was derived from animals that had died less than 3 y before ivory was confiscated. This indicates that the assumption of recent elephant death for mortality estimates of African elephants is correct: Very little “old” ivory is included in large ivory shipments from Africa. We found only one specimen of the 231 analyzed to have a lag time longer than 6 y. Patterns of trade differ by regions: East African ivory, based on genetic assignments of geographic origin, has a much higher fraction of “rapid” transit than ivory originating in the Tridom region of Cameroon-Gabon-Congo. Carbon-14 is an important tool in understanding patterns of movement of illegal wildlife products.

The illegal ivory trade recently intensified to the highest levels ever reported. Policing this trafficking has been hampered by the inability to reliably determine geographic origin of contraband ivory. Ivory can be smuggled across multiple international borders and along numerous trade routes, making poaching hotspots and potential trade routes difficult to identify. This fluidity also makes it difficult to refute a country's denial of poaching problems. We extend an innovative DNA assignment method to determine the geographic origin(s) of large elephant ivory seizures. A Voronoi tessellation method is used that utilizes genetic similarities across tusks to simultaneously infer the origin of multiple samples that could have one or more common origin(s). We show that this joint analysis performs better than sample-by-sample methods in assigning sample clusters of known origin. The joint method is then used to infer the geographic origin of the largest ivory seizure since the 1989 ivory trade ban. Wildlife authorities initially suspected that this ivory came from multiple locations across forest and savanna Africa. However, we show that the ivory was entirely from savanna elephants, most probably originating from a narrow east-to-west band of southern Africa, centered on Zambia. These findings enabled law enforcement to focus their investigation to a smaller area and fewer trade routes and led to changes within the Zambian government to improve antipoaching efforts. Such outcomes demonstrate the potential of genetic analyses to help combat the expanding wildlife trade by identifying origin(s) of large seizures of contraband ivory. Broader applications to wildlife trade are discussed.

To describe the organizational and operational capabilities of specialized centres for children with psychomotor disability in Abidjan, Republic of Côte d'Ivoire. This descriptive study was carried out from February to May, 2006 at the various specialized centres for children with psychomotor disability that exist in the district of Abidjan. The procedure comprised a clinical description of the disabled children admitted to these centres and an assessment of the centres' organization and operational capabilities. Six specialist centres for children with psychomotor disability were identified, namely the Infant Guidance Centre, the Awakening and Stimulation Centre for disabled Children, the "Sainte-Magdeleine" Centre, the Medical and Training Institute, the "Page Blanche" institute and the "Colombes Notre Dame de la Paix" Centre. Among the children, 97.15% were day patients, 66.37% were mentally challenged, 30.96% had psychomotor impairment and 2.66% had motor impairments. The level of organization varied but the centres nevertheless had operational administrative, medical and paramedical staff, despite the absence of certain specialties. However, the lack of personnel, equipment and infrastructure is hindering the delivery of adequate services to the children. In Abidjan District, reception centres for children with psychomotor impairments are essentially privately run. Organizational and operational performances were suboptimal, with a low carer-to-patient ratio. Reinforcement of the centres' operational capabilities appears to be necessary.

A fast, convenient way to determine the age of bones and ivories is important both in forensics and for classifying art objects in collections of art experts, restorers, art galleries and museums. Knowing the age of elephant tusks is also essential because there are many date-specific regulations of ivory trade. Radiocarbon dating is the standard method used to determine the age of organic materials, but it is expensive, time consuming, and damages the sample in the process. Raman spectroscopy is sensitive to rotational and vibrational molecular transitions, and also intermolecular vibrations. Therefore, it can provide information about sample make up, such as proteins and minerals, as well as detect spectral signatures associated with structural changes in molecules. Since Raman spectroscopy identifies the molecular bonds present in a sample, it is often used to determine its chemical composition. Bones and ivories contain two primary components: collagen and bioapatite. As the protein collagen deteriorates with time, its Raman signal decreases. The ratio of collagen-to-bioapatite peaks, therefore, is smaller in the older samples compared to the younger ones, providing a basis for sample dating. We employed Raman spectroscopy to non-destructively determine the age of several elephant tusk fragments. We have also used it to identify ivory imitations made of vegetable and plastic materials. Such materials have entirely different chemical composition, and their spectra are easily distinguished from those of bone and ivory. Peak fitting was employed to determine collagen and bioapatite components.

The lack of data on neonatal tetanus and children in university hospitals (UH) in Abidjan for over a decade has motivated the realization of this study. The objective of this study is to evaluate the morbidity and mortality related to neonatal tetanus (NT) and child tetanus (CT) in Abidjan University Hospital from 2001 to 2010. It is a retrospective study, multicenter analysis with records of newborns and children suffering from tetanus in the three UH of Abidjan. The collection and analysis of data were made by the SPHINX 4.5 and EPI.INFO 6.0 software. In ten years, 242 cases of tetanus (53 NT cases and 189 CT cases) were collected with a predominance of cases after the fifth year of life (59.5%). The incidence rate of NT was less than 1 case per 1,000 live births. All mothers of the newborns were inhabiting the city of Abidjan. Their median age was 19 years [16-32] and 64% were teenagers. Gateways were dominated by umbilical wounds (77.3%) in the NTand skin wounds (59%) in CT. The cure rate was 30.2% in the NT and 60% in the CT. Lethality was 60% for NT and 22% for CT with a positive correlation with young age (neonates: p = 4.10-7, age <5 years: p = 0.01), lack of intraspinal injection of tetanus serum (p = 8.10-6), the absence of conventional antibiotic therapy (p = 0.023), the existence of metabolic complications (p = 2.10-5), the score of ≥ 4 Dakar (p = 0.005). Tetanus remains a real morbidly cause among children in Abidjan University Hospital with high lethality. However, the incidence of NT seems consistent with the incidence threshold desired by WHO.

In 2004, an International Continental Scientific Drilling Program (ICDP) drilling project at the Bosumtwi impact crater, Ghana (10.5 km in diameter, 1.07 Myr old), was performed to study the sediments that fill the lake as well as the underlying impactites. In one (LB-05) of 16 cores drilled into the lake sediments, the zone between the impact breccias and the post-impact sediments was penetrated, preserving the final, fine-grained impact fallback layer. This ~30 cm thick layer contains in the top 10 cm “accretionary” lapilli, microtektite-like glass spherules, and shocked quartz grains. Glass particles -- mostly of splash form less than 1 mm size -- make up the bulk of the grains (~70-78% by number) in the coarser size fraction (>125 μm) of the top of the fallback layer. About one-third of all quartz grains in the uppermost part of the layer are shocked, with planar deformation features (PDFs); almost half of these grains are highly shocked, with 3 or more sets of PDFs. K-feldspar grains also occur and some show shock deformation. The abundance of shocked quartz grains and the average shock level as indicated by the number of sets of PDFs, for both quartz and K-feldspar, decrease with depth into the layer. The well-preserved glass spherules and fragments are chemically rather homogeneous within each particle, and also show relatively small variations between the various particles. On average, the composition of the fallback spherules from core LB-5B is very similar to the composition of Ivory Coast tektites and microtektites, with the exception of CaO contents, which are about 1.5 to 2 times higher in the fallback spherules. This is a rare case in which the uppermost fallback layer and the transition to the post-impact sediments has been preserved in an impact structure; its presence indicates that the impactite sequence at Bosumtwi is complete and that Bosumtwi is a very well-preserved impact crater.

For an efficient struggle against infectious diseases with epidemic potential, the Cdte d'Ivoire set up a precocious alert system in 2001 with a main objective: to detect epidemics of cholera, measles, yellow fever and meningitis and to provide necessary information for their control and their prevention. During the 2001 to 2005 period, the country was marked by military and political crisis which occurred in 2002; the country had to face up to a reappearance of cholera. How did it evolve in such a context? The question was to describe the performances of the system and the evolution of cholera from weekly data collected by the centers of epidemiological monitoring in health districts. The cases and declared deaths were compiled and the indicators of morbidity and mortality were then studied according to time site and individual features on the period of 2001 to 2005. From 2001 to 2005, 11,874 cases were notified with 564 deaths and a lethal rate of 4.7%. In 2001, from the initial source of infection, the civil jail, the epidemic of cholera disseminated itself through visitors in the whole city of Abidjan where 3250 cases were notified. Out of city, 20 outbreaks have been declared with a total of 3010 cases. The yearly highest impact, 37 living cases/100,000 inhabitants recorded in 2001, decreased regularly until 2005 with 0.2 living cases/100,000. After 2002, outbreaks were located mainly in the half south of the country which welcomed displaced populations from the north, preferably in transition or settling zones near the front line. The lethal rate in Abidjan (2.3%) was less important than that of other health districts (8.6%). The lethal rate globally increased as the impact decreased. Vibrio cholerae was responsible for the epidemics. The group of 15 years old and over was the most affected (12.69 living cases/100,000) whereas the highest lethal rate appeared in the group under 5 years old (6.6%).

Genotyping ivory samples can determine the geographic origin of poached ivory as well as the legality of ivory being sold in ivory markets. We conducted a series of experiments to determine where the DNA is most concentrated in ivory samples and how best to increase DNA yield from groups of samples likely to vary in DNA concentration. We examined variation in DNA amplification success from: the layer(s) of the tusk (cementum and/or dentine) being extracted, demineralization temperature and time, and the concentration of eluates. Since demineralization of the pulverized sample produces a pellet and supernatant, we also assessed DNA amplification success from the pellet, the supernatant, their combination, as well as variation in the respective amounts used for extraction. Our results show that the outer cementum layer of the tusk contains the highest concentration of DNA and should be separated and used exclusively as the source material of ivory processed for extraction, when available. Utilizing the combined demineralized lysate improves extraction efficiency, as does increasing demineralization time to 3 or more days, conducted at 4°C. The most significant improvements occurred for low template DNA ivory samples followed by medium quality samples. Amplification success of high quality samples was not affected by these changes. Application of this optimized method to 3068 ivory samples resulted in 81.2% of samples being confirmed for both alleles at a minimum of 10 out of 16 microsatellite loci, which is our threshold for inclusion in DNA assignment analyses.

In Abidjan, Côte d'Ivoire, 18% of men who have sex with men (MSM) are HIV-positive. Based on ethnographic research conducted among HIV peer educators and activists in Abidjan, I examine their narratives and hand-drawn maps of city space. I draw on a methodological process of map-making to examine research participants' evaluations of neighborhoods and link these evaluations to debates over national and cultural belonging in Côte d'Ivoire. I suggest a moral geography emerges from the maps and narratives and ask what the bioethical implications of moral geography are in the context of service delivery and activism among sexual minorities.

The illegal trade in elephant ivory is driving the unlawful killing of elephants such that populations are now suffering unsustainable reductions. The internet is increasingly being used as a platform to conduct illegal wildlife trade, including elephant ivory. As a globally accessible medium the internet is as highly attractive to those involved in the illegal trade as it is challenging to regulate. Characterising the online illegal wildlife (ivory) trade is complex, yet key to informing enforcement activities. We applied mark-recapture to investigate behaviour associated with the online trade in elephant ivory on eBay UK as a generalist online marketplace. Our results indicate that trade takes place via eBay UK, despite its policy prohibiting this, and that two distinct trading populations exist, characterised by the pattern of their ivory sales. We suggest these may represent a large number of occasional (or non-commercial) sellers and a smaller number of dedicated (or commercial) sellers. Directing resource towards reducing the volume of occasional sales, such as through education, would enable greater focus to be placed upon characterising the extent and value of the illegal, "commercial" online ivory trade. MRC has the potential to characterise the illegal trade in ivory and diverse wildlife commodities traded using various online platforms.

Tobacco smoking is a scourge that continues to increase in developing countries despite its known consequences. Is the population of the Ivory Coast sufficiently informed about the consequences of smoking? For this reason, we decided to evaluate the knowledge of the effects of smoking among the people of Abidjan. To evaluate the knowledge of the effects of smoking in the population of Abidjan. To relate this knowledge to the educational level and smoking status. We evaluated knowledge about smoking and its consequences as a function of educational level and smoking status in the population of Abidjan over the age of 15 years. This was undertaken in 3 months, from November 2005 to January 2006, in the two busiest communes in Abidjan. The minimum number of persons required was 1152 but, in fact, we interviewed 1409. The prevalence of smoking was 36.5% with a predominance of males (sex ratio = 3:11). They were mainly young with a mean age of 27.44 years. This population's main sources of information on the ill effects of smoking were the mass media. In general, the subjects did not have a good understanding of smoking and its consequences. With regard to the diseases related to smoking, bronchial carcinoma and cardiovascular disorders were the best known, in 53.1 and 18.1%, respectively. With regard to the components of tobacco, nicotine was the best known (92.6%). Knowledge was related to the level of education: the subjects of a higher educational level were the most knowledgeable about the consequences of smoking. As a result, these subjects were less attached to smoking than the less educated. The consequences of smoking are poorly understood by the general population. With regard to the level of education, the better educated had a better understanding of the effects of smoking and were also those who smoked the least. Copyright 2010.

Illegal wildlife trade has reached alarming levels globally, extirpating populations of commercially valuable species. As a driver of biodiversity loss, quantifying illegal harvest is essential for conservation and sociopolitical affairs but notoriously difficult. Here we combine field-based carcass monitoring with fine-scale demographic data from an intensively studied wild African elephant population in Samburu, Kenya, to partition mortality into natural and illegal causes. We then expand our analytical framework to model illegal killing rates and population trends of elephants at regional and continental scales using carcass data collected by a Convention on International Trade in Endangered Species program. At the intensively monitored site, illegal killing increased markedly after 2008 and was correlated strongly with the local black market ivory price and increased seizures of ivory destined for China. More broadly, results from application to continental data indicated illegal killing levels were unsustainable for the species between 2010 and 2012, peaking to ∼ 8% in 2011 which extrapolates to ∼ 40,000 elephants illegally killed and a probable species reduction of ∼ 3% that year. Preliminary data from 2013 indicate overharvesting continued. In contrast to the rest of Africa, our analysis corroborates that Central African forest elephants experienced decline throughout the last decade. These results provide the most comprehensive assessment of illegal ivory harvest to date and confirm that current ivory consumption is not sustainable. Further, our approach provides a powerful basis to determine cryptic mortality and gain understanding of the demography of at-risk species.

Osmium isotope data had shown that Ivory Coast tektites contain an extraterrestrial component, but do not allow distinction between chondritic and iron meteorite contamination. PGE abundances of Ivory Coast tektites and impactites and target rocks from the Bosumtwi crater, the source crater of the Ivory Coast tektites, were all relatively high and did not allow to resolve the presence, or identify the nature, of the meteoritic component. However, Cr isotope analyses of an Ivory Coast tektite yielded a distinct 53Cr excess of 0.30+/-0.06, which indicates that the Bosumtwi impactor was an ordinary chondrite.

International wildlife crime is burgeoning in this climate of global trade. We contend that the most effective way to contain this illegal trade is to determine where the wildlife is being removed. This allows authorities to direct law enforcement to poaching hot spots, potentially stops trade before the wildlife is actually killed, prevents countries from denying their poaching problems at home, and thwarts trade before it enters into an increasingly complex web of international criminal activity. Forensic tools have been limited in their ability to determine product origin because the information they can provide typically begins only at the point of shipment. DNA assignment analyses can determine product origin, but its use has been limited by the inability to assign samples to locations where reference samples do not exist. We applied new DNA assignment methods that can determine the geographic origin(s) of wildlife products from anywhere within its range. We used these methods to examine the geographic origin(s) of 2 strings of seizures involving large volumes of elephant ivory, 1 string seized in Singapore and Malawi and the other in Hong Kong and Cameroon. These ivory traffickers may comprise 2 of the largest poaching rings in Africa. In both cases all ivory seized in the string had common origins, which indicates that crime syndicates are targeting specific populations for intense exploitation. This result contradicts the dominant belief that dealers are using a decentralized plan of procuring ivory stocks as they became available across Africa. Large quantities of ivory were then moved, in multiple shipments, through an intermediate country prior to shipment to Asia, as a risk-reduction strategy that distances the dealer from the poaching locale. These smuggling strategies could not have been detected by forensic information, which typically begins only at the shipping source.

Background Currently, there is a significant lack of knowledge concerning urban malaria patterns in general and in Abidjan in particular. The prevalence of malaria, its distribution in the city and the fractions of fevers attributable to malaria in the health facilities have not been previously investigated. Methods A health facility-based survey and health care system evaluation was carried out in a peripheral municipality of Abidjan (Yopougon) during the rainy season of 2002, applying a standardized Rapid Urban Malaria Appraisal (RUMA) methodology. Results According to national statistics, approximately 240,000 malaria cases (both clinical cases and laboratory confirmed cases) were reported by health facilities in the whole of Abidjan in 2001. They accounted for 40% of all consultations. In the health facilities of the Yopougon municipality, the malaria infection rates in fever cases for different age groups were 22.1% (under one year-olds), 42.8% (one to five years-olds), 42.0% (> five to 15 years-olds) and 26.8% (over 15 years-olds), while those in the control group were 13.0%. 26.7%, 21.8% and 14.6%, respectively. The fractions of malaria-attributable fever were 0.12, 0.22, 0.27 and 0.13 in the same age groups. Parasitaemia was homogenously detected in different areas of Yopougon. Among all children, 10.1% used a mosquito net (treated or not) the night before the survey and this was protective (OR = 0.52, 95% CI 0.29–0.97). Travel to rural areas within the last three months was frequent (31% of all respondents) and associated with a malaria infection (OR = 1.75, 95% CI 1.25–2.45). Conclusion Rapid urbanization has changed malaria epidemiology in Abidjan and endemicity was found to be moderate in Yopougon. Routine health statistics are not fully reliable to assess the burden of disease, and the low level of the fractions of malaria-attributable fevers indicated substantial over-treatment of malaria.

Demand for ivory and expansion of human settlements have resulted in a rapid decline in the number of elephants. Enforcement of local and international laws and regulations requires identification of the species from which any ivory, or ivory products, originated. Further geographical assignment of the dead elephant from which the ivory was taken can assist in forensic investigations. In this study, a real-time PCR assay using melt curve analysis was developed and fully validated for forensic use. The presence or absence of three Elephantidae-specific and elephant species-specific melting peaks was used to identify the elephant species. Using 141 blood and ivory samples from the three extant elephant species, the assay demonstrated very high reproducibility and accuracy. The limit of detection was as low as 0.031ng of input DNA for conventional amplification and 0.002ng for nested amplification. Both DNA concentrations are typically encountered in forensic casework, especially for degraded samples. No cross-reactivity was observed for non-target species. Evaluation of direct amplification and nested amplification demonstrated the assay's flexibility and capability of analyzing low-template DNA samples and aged samples. Additionally, blind trial testing showed the assay's suitability application in real casework. In conclusion, wildlife forensic laboratories could use this novel, quick, and low-cost assay to help combat the continuing poaching crises leading to the collapse of elephant numbers in the wild.

Illegal wildlife trade has reached alarming levels globally, extirpating populations of commercially valuable species. As a driver of biodiversity loss, quantifying illegal harvest is essential for conservation and sociopolitical affairs but notoriously difficult. Here we combine field-based carcass monitoring with fine-scale demographic data from an intensively studied wild African elephant population in Samburu, Kenya, to partition mortality into natural and illegal causes. We then expand our analytical framework to model illegal killing rates and population trends of elephants at regional and continental scales using carcass data collected by a Convention on International Trade in Endangered Species program. At the intensively monitored site, illegal killing increased markedly after 2008 and was correlated strongly with the local black market ivory price and increased seizures of ivory destined for China. More broadly, results from application to continental data indicated illegal killing levels were unsustainable for the species between 2010 and 2012, peaking to ∼8% in 2011 which extrapolates to ∼40,000 elephants illegally killed and a probable species reduction of ∼3% that year. Preliminary data from 2013 indicate overharvesting continued. In contrast to the rest of Africa, our analysis corroborates that Central African forest elephants experienced decline throughout the last decade. These results provide the most comprehensive assessment of illegal ivory harvest to date and confirm that current ivory consumption is not sustainable. Further, our approach provides a powerful basis to determine cryptic mortality and gain understanding of the demography of at-risk species. PMID:25136107

The dried endosperm of the seed of Phytelephas sp is widely used for artisanal work in the Amazon region due to its favorable mechanical properties and pleasant appearance that resemble elephant ivory. While the seeds have enjoyed popularity and limited use by selected industries (e.g., military uniform buttons and piano keys) and handicraft applications, little is known about the mechanical properties and structure of this sustainable material. This work is the first to characterize the dried Jarina endosperm and to investigate its functionality as a viable substitute for elephant ivory. Structural analysis of typical seeds reveals the prevalence of tubules that align in rings and radiate from the (usually hollow) core of the seed. This seed, in the absence of a reinforcement structure or mineral phase, possesses mechanical properties slightly inferior to elephant ivory and selected plastics, while retaining the visual appeal of a naturally occurring material. A synthetic structure inspired on the seed is created and suggestions for further development are discussed.

Air quality observations in the major cities of South-Western Africa still remains few with regards to economic growth and the large increase in the urban population. The main cities lying on the Gulf of Guinea experiences low air quality because of the contribution of local emissions and advection of pollutants from the African continent. We present in this paper new observations acquired from February 2015 to March 2017 in the major cities of Cotonou (Bénin) and Abidjan (Côte d'Ivoire). The PM2.5 mass concentration and carbon composition (elemental and organic carbon) were recorded on a weekly basis at 4 different locations representative of major emission sources, i.e. traffic emission, domestic fire and waste burning. Additionally, the aerosol optical depth (AOD) was also recorded daily inside and outside the cities. We observe large similarly between both cities. The mean PM2.5 concentration of around 30 µg.m-3 is coherent with previous studies for sub-Saharan western Africa and is 3 times higher than the concentrations recommended by the World Health Organization. The sampled collected at the domestic fire site shows a large pollution by smoking activity with an average concentration of 145 µg.m-3, nearly 5 times the traffic background. The seasonality of PM2.5 is affected by the contribution of desert dust and biomass burning emissions that is clearly observed from the AOD time series. We observe that dust events contribute sporadically to large amount of PM2.5, above 100 µg.m-3, during the dry seasons. Moreover, the biomass burning activity is also maximum before and during the dry season and contributes to increase the PM2.5 concentration. Low PM2.5 observed during the minor dry season can be explain by an enhancement of the atmospheric dispersion due to the increase in the wind intensity and the absence of biomass burning activity. We observe a significant difference in the carbonaceous aerosols between the traffic site in Abidjan and Cotonou. The

The Zoo National d'Abidjan (Abidjan Zoo) in Côte d'Ivoire, West Africa, holds the world's largest captive population of African slender-snouted crocodiles (Mecistops cataphractus, formerly Crocodylus cataphractus), at 36 adults, 16 yearlings, and 23 hatchlings. Twelve yearling and 12 adult slender-snouted crocodiles at the Abidjan Zoo were restrained for physical exam, body condition scoring, and venipuncture in September 2015. Blood samples collected from the supravertebral venous sinus were analyzed using a handheld blood analyzer (Abaxis® I-stat, Abaxis, Inc., Union City, California 94587, USA) with Chem8+ cartridges (CLIAwaived, Inc., San Diego, California 92130, USA). The adult crocodiles appeared in good general health and demonstrated blood values similar to those of other reptiles. The yearlings had low, ionized calcium values and low hematocrit and hemoglobin levels compared with the adult crocodiles and to other crocodile reference ranges. These findings may dramatically improve the health of the crocodiles and help to ensure a thriving captive population of this critically endangered species.

This study was carried in the intensive care units of Abidjan university hospitals and in the herpetology department of Pasteur Institute between January 2001 and April 2003. The purpose was to identify ophidian species that were dangerous for man and to document cases of snakebite in Abidjan. The study was carried out in two phases, i.e., collection and identification of snake species followed by review of case records involving snake envenomation at Cocody and Treichville university hospitals. A total of 5 snake families, 14 genera and 17 species including some that were dangerous for man were identified. All species except Naja nigricollis live in forest areas. Most snakebites led to simple clinical signs that regressed within 72 hours with only symptomatic treatment. However, a few cases required immunotherapy. Traditional methods of snakebite treatment were used for first line treatment in 50% of cases.

This paper critically reviews an experience of health cooperation in an hospital of a rural area of Ivory Coast. This particular situation is analysed in the more general frame of health problems in low-income countries and may suggest priorities for international health cooperation. The analysis of the main causes of avoidable death in poor countries does indicate targets and tools of intervention. In this case, the target was the reduction of infant mortality from anaemia of different origin and from HIV-1 mother-to-infant transmission. The major tool for intervention was the partnership between an Italian teaching and research hospital and the African hospital, with the catalyst of a non-governmental organisation. This paper analyses the different levels at which cooperation developed in this project, from sheer economic support to the implementation of disease-oriented twinning programs that can improve health care and strengthen research capacity on both sides. Besides, medical, ethical and social implications of the ongoing cooperation program are discussed, with particular reference to the problems of preventing mortality from severe anaemia (diet fortification in children and pregnancy and transfusional guidelines in severe malaria) and of preventing mother-to-child neonatal transmission of HIV-1 infection (counselling and testing pregnant women for HIV-1, nevirapine administering to the mother and the baby and breast-feeding).

In the framework of the Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) project, the tropospheric chemical composition in large cities along the Gulf of Guinea is studied using the Weather and Research Forecast and CHIMERE regional models. Simulations are performed for the May-July 2014 period, without and with biomass burning emissions. Model results are compared to satellite data and surface measurements. Using numerical tracer release experiments, it is shown that the biomass burning emissions in Central Africa are impacting the surface aerosol and gaseous species concentrations in Gulf of Guinea cities such as Lagos (Nigeria) and Abidjan (Ivory Coast). Depending on the altitude of the injection of these emissions, the pollutants follow different pathways: directly along the coast or over land towards the Sahel before being vertically mixed in the convective boundary layer and transported to the south-west and over the cities. In July 2014, the maximum increase in surface concentrations due to fires in Central Africa is ≈ 150 µg m-3 for CO, ≈ 10 to 20 µg m-3 for O3 and ≈ 5 µg m-3 for PM10. The analysis of the PM10 chemical composition shows that this increase is mainly related to an increase in particulate primary and organic matter.

Air quality degradation is a major issue in the large conurbations on the shore of the Gulf of Guinea. We present for the first time PM2.5 time series collected in Cotonou, Benin, and Abidjan, Côte d'Ivoire, from February 2015 to March 2017. Measurements were performed in the vicinity of major combustion aerosol sources: Cotonou/traffic (CT), Abidjan/traffic (AT), Abidjan/landfill (AL) and Abidjan/domestic fires (ADF). We report the weekly PM2.5 mass and carbonaceous content as elemental (EC) and organic (OC) carbon concentrations. We also measure the aerosol optical depth (AOD) and the Ångström exponent in both cities. The average PM2.5 mass concentrations were 32 ± 32, 32 ± 24 and 28 ± 19 µg m-3 at traffic sites CT and AT and landfill site AL, respectively. The domestic fire site shows a concentration of 145 ± 69 µg m-3 due to the contribution of smoking and roasting activities. The highest OC and EC concentrations were also measured at ADF at 71 ± 29 and 15 ± 9 µg m-3, respectively, while the other sites present OC concentration between 8 and 12 µg m-3 and EC concentrations between 2 and 7 µg m-3. The OC / EC ratio is 4.3 at CT and 2.0 at AT. This difference highlights the influence of two-wheel vehicles using gasoline in Cotonou compared to that of four-wheel vehicles using diesel fuel in Abidjan. AOD was rather similar in both cities, with a mean value of 0.58 in Cotonou and of 0.68 in Abidjan. The seasonal cycle is dominated by the large increase in surface mass concentration and AOD during the long dry season (December-February) as expected due to mineral dust advection and biomass burning activities. The lowest concentrations are observed during the short dry season (August-September) due to an increase in surface wind speed leading to a better ventilation. On the other hand, the high PM2.5 / AOD ratio in the short wet season (October-November) indicates the stagnation of local pollution.

To compare the spontaneous cocoa bean fermentation process carried out in different cocoa-producing regions, heap and box (one Ivorian farm) and box (two Brazilian farms) fermentations were carried out. All fermentations were studied through a multiphasic approach. In general, the temperature inside the fermenting mass increased throughout all fermentations and reached end-values of 42-48 °C. The main end-products of pulp carbohydrate catabolism were ethanol, lactic acid, acetic acid, and/or mannitol. In the case of the fermentations on the selected Ivorian farm, the species diversity of lactic acid bacteria (LAB) and acetic acid bacteria (AAB) was restricted. Lactobacillus fermentum and Leuconostoc pseudomesenteroides were the predominant LAB species, due to their ethanol and acid tolerance and citrate consumption. The levels of mannitol, ascribed to growth of L. fermentum, were fermentation-dependent. Also, enterobacterial species, such as Erwinia soli and Pantoea sp., were among the predominating microbiota during the early stages of both heap and box fermentations in Ivory Coast, which could be responsible for gluconic acid production. Consumption of gluconic acid at the initial phases of the Ivorian fermentations could be due to yeast growth. A wider microbial species diversity throughout the fermentation process was seen in the case of the box fermentations on the selected Brazilian farms, which differed, amongst other factors, regarding pod/bean selection on these farms as compared to fermentations on the selected Ivorian farm. This microbiota included Lactobacillus plantarum, Lactobacillus durianis, L. fermentum, Lactobacillus mali, Lactobacillus nagelii, L. pseudomesenteroides, and Pediococcus acidilactici, as well as Bacillus subtilis that was present at late fermentation, when the temperature inside the fermenting mass reached values higher than 50 °C. Moreover, AAB seemed to dominate the Brazilian box fermentations studied, explaining higher acetic

In temperate regions, influenza epidemics occur in the winter and correlate with certain climatological parameters. In African tropical regions, the effects of climatological parameters on influenza epidemics are not well defined. This study aims to identify and model the effects of climatological parameters on seasonal influenza activity in Abidjan, Cote d'Ivoire. We studied the effects of weekly rainfall, humidity, and temperature on laboratory-confirmed influenza cases in Abidjan from 2007 to 2010. We used the Box-Jenkins method with the autoregressive integrated moving average (ARIMA) process to create models using data from 2007-2010 and to assess the predictive value of best model on data from 2011 to 2012. The weekly number of influenza cases showed significant cross-correlation with certain prior weeks for both rainfall, and relative humidity. The best fitting multivariate model (ARIMAX (2,0,0) _RF) included the number of influenza cases during 1-week and 2-weeks prior, and the rainfall during the current week and 5-weeks prior. The performance of this model showed an increase of >3 % for Akaike Information Criterion (AIC) and 2.5 % for Bayesian Information Criterion (BIC) compared to the reference univariate ARIMA (2,0,0). The prediction of the weekly number of influenza cases during 2011-2012 with the best fitting multivariate model (ARIMAX (2,0,0) _RF), showed that the observed values were within the 95 % confidence interval of the predicted values during 97 of 104 weeks. Including rainfall increases the performances of fitted and predicted models. The timing of influenza in Abidjan can be partially explained by rainfall influence, in a setting with little change in temperature throughout the year. These findings can help clinicians to anticipate influenza cases during the rainy season by implementing preventive measures.

To determine HIV prevalence and associated risk factors among men who have sex with men (MSM) in Abidjan, Côte d’Ivoire. We conducted a cross-sectional RDS survey of MSM in Abidjan from October 2011 to February 2012. Eligibility criteria included age ≥ 18 years and having had oral or anal sex with another man in the last 12 months. Weighted data analysis was conducted with RDSAT and SAS. We enrolled 603 participants, of whom 601 (99.7%) completed the questionnaire and 581 (96.7%) consented to HIV testing. HIV population prevalence was estimated as 18.0% (95% CI: 13.0-23.1); 86.4% (95% CI: 75.1-94.9) of HIV-positive MSM were unaware of their serostatus. In multivariable analysis, adjusting for age, education, and income, HIV infection was associated with unprotected sex at last sex with a woman, more than two male anal sex partners in last 12 months, inconsistent condom use during anal sex with a man, self-perceived risk of HIV, history of forced sex, history of physical abuse due to MSM status, and not receiving last HIV test result prior to study. HIV prevalence among MSM in Abidjan is more than four times as high as that of general population men. MSM engage in high-risk sexual behavior and most HIV-positive MSM are unaware of their serostatus. Greater access to HIV prevention, care, and treatment services targeted to MSM is necessary.

Novel psychoactive substances or 'legal highs' can be defined as psychoactive substances that have been developed to avoid existing drug control measures. Consistency of name, but with change in the content of the product, may cause harm. This could result in clusters of users being poisoned and developing unexpected physical and psychiatric symptoms. We describe such an event and the clinical phenotypes of a cluster of patients poisoned with a novel psychoactive substance in 'ivory wave' and analyze data from the National Poisons Information Service (NPIS) to estimate use across the United Kingdom. In addition, the likely active ingredient in this cluster of 'ivory wave' poisonings was identified. An analysis of consecutive patients attending the Royal Infirmary of Edinburgh emergency department in July and August 2010 with self-reported 'ivory wave' use was performed. Over a similar time frame, poisons enquiries regarding 'ivory wave' to the UK NPIS, by telephone and via the internet-based TOXBASE(®) poisons database ( www.toxbase.org ), were analyzed. A sample of 'ivory wave' powder and biological fluids from poisoned patients were investigated to determine the active ingredient. Thirty four emergency attendances due to 'ivory wave' toxicity were identified. The mean +/- SD (range) age was 28.6 +/- 7.8 (16-44) years. Patients demonstrated a toxidrome which lasted several days, characterized by tachycardia (65%), tachypnoea (76%), dystonia (18%), rhabdomyolysis (96%), leucocytosis (57%), agitation (62%), hallucinations (50%), insomnia (32%) and paranoia (21%). Enquiries to NPIS suggest that 'ivory wave' poisoning occurred throughout the United Kingdom. A sample of 'ivory wave' powder was analyzed and found to contain desoxypipradrol, which was also identified in biological fluids from 4 out of 5 patients tested. A cluster of cases presenting after use of a novel psychoactive substance was identified in Edinburgh and desoxypipradrol was identified as the likely

Macroscopic, periodic, dark and bright patterns are observed on sections of elephant tusk, in the dentin part (ivory). The motifs—also called Schreger pattern—vary depending on the orientation in the tusk: on sections perpendicular to the tusk axis, a checkerboard pattern is present whereas on sections longitudinal to it, alternating stripes are observed. This pattern has been used to identify elephant and mammoth ivory in archeological artifacts and informs on the continuous tissue growth mechanisms of tusk. However, its origin, assumed to be related to the 3D structure of empty microtubules surrounded by the ivory matrix has yet to be characterized unequivocally. Based on 2D observations of the ivory microtubules by means of a variety of imaging techniques of three different planes (transverse, longitudinal and tangential to the tusk axis), we show that the dark areas of the macroscopic pattern are due to tubules oblique to the surface whereas bright areas are related to tubules parallel to it. The different microstructures observed in the three planes as well as the 3D data obtained by SR-μCT analysis allow us to propose a 3D model of the microtubule network with helical tubules phase-shifted in the tangential direction. The phase shift is a combination of a continuous phase shift of π every 1 mm with a stepwise phase shift of π/2 every 500 μm. By using 3D modeling, we show how the 3D helical model better represents the experimental microstructure observed in 2D planes compared to previous models in the literature. This brings new information on the origin of the unique Schreger pattern of elephant ivory, crucial for better understanding how archaeological objects were processed and for opening new routes to rethink how biological materials are built.

A survey of achievement in primary education in the Ivory Coast shows that the results of girls are inferior to those of boys in all subjects and at all levels of schooling. Concerning the learning of French (the language of instruction in the Ivory Coast), the situation differs from that observed in a number of industrialised countries, where the performance of girls is generally superior to that of boys in subjects linked to language learning. On the other hand, it conforms to the situation observed in other developing countries, where boys most frequently show superior results. This pattern of results suggests that the differences in achievement between the sexes are of a cultural origin. Analysis of factors associated with these differences in the Ivory Coast seems to confirm this hypothesis: First, society in the Ivory Coast attaches less importance to the educational achievements of girls than of boys. Girls go to school less often than boys or leave school more readily than boys. They less often express the desire to continue their studies beyond the primary school.

The ivory gull (Pagophila eburnea) is a circumpolar marine bird which has recently been listed as an endangered species in Canada. To determine whether contaminants may be playing a role in the population decline of this species, ivory gull eggs collected in 1976, 1987 and 2004 from Seymour Island in the Canadian Arctic were analyzed for organochlorines, polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and non-ortho PCBs. This study also provides the first account of polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDs) and polybrominated biphenyls (PBBs) in ivory gulls. The most quantitatively abundant legacy organochlorines found in the ivory gull eggs were p,p'-DDE, SigmaPCB and oxychlordane. Concentrations of the organochlorines analyzed either decreased or showed little change between 1976 and 2004. Concentrations of SigmaPCDD in ivory gull eggs were greater than SigmaPCDF, and the non-ortho PCBs (primarily PCB-126) contributed the largest fraction to the total TEQ value in all years sampled. Concentrations of PCDDs, PCDFs and SigmaTEQ decreased from 1976 to 2004. In contrast, concentrations of the PBDEs steadily increased between 1976 and 2004 driven primarily by increases in BDE-47. Although concentrations of the persistent chlorinated compounds (i.e. organochlorine pesticides, PCBs, PCDDs, PCDFs) reported in this study were below published toxicological threshold values for eggs of wild birds, we cannot rule out the possibility of synergistic/additive, sublethal effects. Very few studies have been carried out to evaluate the exposure-effect relationship of the persistent brominated compounds in avian species. Given the scarcity of information on toxicity threshold levels for PBBs and PBDEs in avian species, coupled with the trend toward increasing concentrations in ivory gulls, continued monitoring and further toxicological studies of these compounds are warranted.

The objective of this project is to carry out a comparative analysis of two urban environments with remote sensing and Geographic Informations Systems, integrating multi-source data. The city of Abidjan (Cote d'Ivoire) and Montreal Island (Quebec) were selected. This study lies within the context of the strong demographic and space growths of urban environments. A supervised classification based on the theory of evidence allowed the identification of mixed pixels. However, the accuracy of this method is lower than that of the bayesian theory. Nevertheless, this method showed that the most credible classes (maximum believes in "closed world") are most probable (maximum probabilities) and thus confirms the bayesian maximum-likelihood decision. On the other hand, the contrary is not necessarily true because of the rules of combination. The urban cover map resulting from classification by the maximum likelihood method was then used to determine a relation between the residential surface and the number of inhabitants in a sector. Moreover, the area of green spaces was an input data (environmental component) for the Urban Development Indicator (IDU), the elaborated model for quantifying the quality of life in urban environment. Moreover, this indicator was defined to allow a total and efficient comparison of urban environments. Following a thorough bibliographical review, seven criteria were retained to describe the optimal conditions for the populations well-being. These criteria were then estimated from standardized indices. The choice of these criteria is a function of the availability of the data to be integrated into the GIS. As the criteria selected have not the same importance in the definition of the quality of urban life, one needed to rank by the method of multicriteria hierarchy and to normalize them in order to join them together in only one parameter. The composite indicator IDU thus obtained allowed to establish that Abidjan had an average development in

Savannas currently occupy a fifth of the earth's land surface and are predicted to expand in the next few centuries at the expense of tropical forests, mainly as a result of deforestation and human fires. Can such a vegetation trend impact, through changes in plant Si cycling, the lithogenic silicon (LSi) release into soils (through chemical weathering) and the net dissolved Si (DSi) outputs from soils to stream water (through chemical denudation)? The first step of an investigation requires quantifying the net Si fluxes involved in the plant/soil system. Here, a schematic steady-state Si cycle, established for a tropical humid savanna (Lamto, Ivory Coast) that developed on a ferruginous soil and is subjected to annual fires, is presented. Erosion was assumed to be insignificant. LSi and biogenic Si (BSi under the form of phytoliths) pools were measured, and Si fluxes were estimated from Si concentrations and mass balance calculation. Identification of plant and soil phytoliths indicated that the soil BSi pool is in equilibrium with the current BSi input by the savanna. In the soil column, mixing between a young rapidly recycled BSi pool and an old stable BSi pool is attested by a mixing line equation. Storage of the old BSi pool is assimilated as a BSi output from the plant/soil system. A BSi output additionally occurs after annual fires, when ashes are exported. Both BSi outputs decrease as much the BSi dissolution. In order to uptake constant DSi flux, the savanna increases by three to eight times the net LSi release, depending upon the post-fire ash exportation scenario. A comparison between savanna and rainforest Si cycles that maximizes the differences in plant/soil systems and minimizes differences in climate is presented. The comparison revealed that BSi storage is higher in the savanna soil than in the rainforest soil, mainly due to BSi production that is twice higher in the savanna (127 vs 67 kg/ha/yr). The resulting LSi release that is enhanced by plant

The burden of dengue in Africa is not well understood. A prospective study was conducted in Abidjan, Côte d'Ivoire from December 2011 to December 2012 to estimate the proportion of dengue and malaria cases among febrile patients during a period when dengue was not known to be circulating in the region, and to describe the clinical and virological characteristics of laboratory-diagnosed dengue cases. Blood samples were taken from febrile patients (body temperature ≥ 38°C) at two study sites. Patients with fever lasting more than 7 days, with fever of known origin and with jaundice were excluded. Thick blood film tests, ELISA for anti-dengue IgM and reverse transcription-PCR (RT-PCR) were performed. A total of 812 patients were enrolled (51.7% male [48.3% female]; 46.4% aged <10 years) of whom 796 (98.0%) provided IgM ELISA and RT-PCR data, and 807 (99.4%) had thick blood film results. Three (0.4%) patients had laboratory-diagnosed dengue (one with DENV-3 serotype), none of whom were diagnosed clinically, and 234 (28.8%) had confirmed malaria. This study suggests that dengue virus circulates in Abidjan outside an epidemic and that there should be an increase in awareness of dengue as a possible diagnosis in cases of undifferentiated fever. These results stress the importance of implementing laboratory capacity to assess dengue burden in Africa. © The Author 2015.

Mercury (Hg) is increasing in marine food webs, especially at high latitudes. The bioaccumulation and biomagnification of methyl mercury (MeHg) has serious effects on wildlife, and is most evident in apex predators. The MeHg body burden in birds is the balance of ingestion and excretion, and MeHg in feathers is an effective indicator of overall MeHg burden. Ivory gulls (Pagophila eburnea), which consume ice-associated prey and scavenge marine mammal carcasses, have the highest egg Hg concentrations of any Arctic bird, and the species has declined by more than 80% since the 1980s in Canada. We used feathers from museum specimens from the Canadian Arctic and western Greenland to assess whether exposure to MeHg by ivory gulls increased from 1877 to 2007. Based on constant feather stable-isotope (δ13C, δ15N) values, there was no significant change in ivory gulls' diet over this period, but feather MeHg concentrations increased 45× (from 0.09 to 4.11 µg g−1 in adults). This dramatic change in the absence of a dietary shift is clear evidence of the impact of anthropogenic Hg on this high-latitude threatened species. Bioavailable Hg is expected to increase in the Arctic, raising concern for continued population declines in high-latitude species that are far from sources of environmental contaminants.

Repellents in the form of dermal pomades are recommended as a protection against awakening and bedtime mosquito bites. If synthesis repellents are available, they are nevertheless not common and the prices remain out of reach for the communities concerned. The people therefore have to resort more and more to traditional concoctions, some of which have been shown to be effective. After demonstrating that oil-based formulations (lotions, creams, pomades) of Cocos nucifera (coconut), Elaeis guineensis (oil palm) and Carapa procera (gobi) were effective against mosquitoes, it became necessary to study the impact of the two excipients used in their manufacture, on the effectiveness of the repellents. Experiments were carried with Anopheles gambiae and Aedes aegypti under lobaratory conditions and any other mosquitoes collected under field conditions in Ivory Coast. The laboratory results indicate that the average protection times obtained with formulations with karite nut butter as excipient (54.8 +/- 37.0 mn and 74.6 +/- 26.4 mn respectively on An. gambiae and Ae. aegypti) are higher than those recorded with vaseline as excipient (respectively 42.7 +/- 30.0 mn and 60.8 +/- 33.9 mn). On the other hand, under field conditions, the biting rate percentage reduction obtained with the products with karite nut butter and vaseline excipient were similar (respectively 29.8% and 35.9% for all mosquitoes collected and 45.7% and 47.4% against An. gambiae). Nevertheless, the use of karite nut butter on repellent products should be encouraged because its sale price is very lower (10 time less) than the vaseline's.

Antique objects are known to have been brightly colored. However, the appearance of these objects has changed over time and paint traces are rarely preserved. The surface of ivory objects (8th century B.C., Syria) from the Louvre museum collection (Paris) have been non-invasively studied by simultaneous particle-induced X-ray emission (PIXE) and Rutherford and elastic backscattering spectrometry (RBS/EBS) micro-imaging at the AGLAE facility (C2RMF, Paris). Qualitative 2D chemical images of elements ranging from Na to Pb on the surface of the ancient ivory carvings provide evidence of lost polychromy and gilding. Quantitative PIXE data of specific areas allow discrimination between traces of sediments and former polychromy. Different shades of blue can be differentiated from particular Pb/Cu ratios. The characterization of gilding based on RBS data demonstrates the exceptional technological skills of the Phoenician craftsmen supposed to have carved the Arslan Tash ivories. More precise reconstructions of the original polychromy compared to previous studies and a criterion for the authentication of ancient gilded ivory object are proposed. Copyright © 2015 Elsevier B.V.

An immunization coverage survey was conducted among children aged 12-59 months in a suburban neighbourhood in Abidjan. The objective was to determine the complete immunization coverage, the reasons for non-vaccination and factors influencing the immunization status of children. The method of exhaustive sampling enabled us to interview the mothers of 669 children using a questionnaire. Overall vaccination coverage was 68.6% with 1.2%, with 1.2% of children never having received vaccine. The logistic regression analysis showed that the level of education, knowledge of the immunization schedule and the marital status of mothers, as well as the type of habitat, were associated with full immunization of children. These determinants must be taken into account to improve vaccination coverage.

Since 2008, several outbreaks of yellow fever and dengue occurred in Abidjan, the economic capital of Côte d'Ivoire. A better knowledge of the biology of Aedes aegypti populations, the main vector of yellow fever and dengue viruses, is necessary to tailor vector control strategies implemented in the city. This study was designed to determine some biological parameters, occurring during the life cycle of two morphological phenotypes of Ae. aegypti larvae. Mosquitoes were sampled in a suburb of Abidjan (Treichville) using the WHO layer-traps technique. Biological parameters were studied in laboratory under standard conditions of temperature (27°C ± 2°C) and relative humidity (80% ± 10%). Our results indicated that the mean eggs laid by females from 'brown larvae' (BL) (85.95, 95% confidence interval (CI 95%) 78.87-93.02) was higher than those from 'white larvae' (WL) (64.40%, CI 95% 55.27-73.54). The gonotrophic cycle was 3 and 4 days in females from BL and WL, respectively. The overall yield of breeding mosquitoes from BL (63.88%, CI 95% 62.61-65.14) was higher compared with those of mosquitoes from WL (59.73%, CI 95% 58.35-61.12). The sex ratio (male/female) was 0.95 and 1.68 in Ae. aegypti populations from BL and WL, respectively. Females from BL lived slightly longer than those from WL (t = -2.332; P = 0.021). This study shows that Ae. Aegypti populations from BL and WL present different biological parameters during their life cycle. This could have an implication on their ability to transmit human disease viruses such as dengue and yellow fever. Further molecular studies are needed to determine genetic divergence between these Ae. aegypti populations.

Operational upper-air stations are very sparsely distributed over West Africa, resulting in the necessity to enhance radiosonde observations for the DACCIWA (Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa) experimental period during June-July 2016. Building on the AMMA (African Monsoon - Multidisciplinary Analyses) experience, existing infrastructures, as well as human networks, the upper air network was successfully augmented to a spatial density that is unprecedented for southern West Africa. Altogether, more than 750 experimental radiosondes were launched at seven stations in three countries along the Guinea Coast. From its outset, the DACCIWA radiosonde campaign had three pillars: (a) enhancing soundings at operational or quiescent AMMA radiosonde stations; (b) launching sondes at DACCIWA supersites and two additional DACCIWA field sites; and (c) collecting standard and - if possible - high-resolution data from other operational RS stations. In terms of (a), it was found during preparing recce visits to West Africa, that the AMMA-activated stations of Cotonou (Benin) and Abuja (Nigeria) were operational though almost "invisible" on the World Meteorological Organisation's Global Teleconnection System (GTS). These and other AMMA legacies facilitated the implementation of enhanced, four-times daily soundings at Abidjan (Ivory Coast), Cotonou and Parakou (both Benin). Two well-instrumented DACCIWA ground sites at Kumasi (Ghana) and Savé (Benin) performed 06 UTC soundings, being enhanced to four-times daily ascents during fifteen Intensive Observing Periods (IOPs). In addition, research staff and students from the Karlsruhe Institute of Technology (KIT) and African partners conducted up to five-times daily soundings at Lamto (Ivory Coast) and Accra (Ghana). Almost all of the experimental DACCIWA ascents were submitted to the GTS in real time and assimilated at least at three European numerical weather prediction centres that helped to improve their

This study is a contribution to the WP2-DACCIWA program with the aim to characterize particulate pollution on domestic fire site, traffic sites and waste burning site of two West-African capitals (Abidjan, Cote d'Ivoire and Cotonou, Benin) and to study aerosol biological impacts on lung inflammation. Such an impact is still largely unknown, especially for the particles emitted by intense African traffic sources and domestic fires. In this context, fundamental research of this study is centered on the following key scientific question: what is the link between aerosol size differentiated composition and inflammation markers for the main combustion sources prevailing in South West Africa during dry and wet seasons? To tackle this question, intensive campaigns in Abidjan and Cotonou have been conducted in July 2015, January and July 2016, and January 2017. In this paper, we will present our first results for the campaign of January 2016. In terms of aerosol size differentiated composition, main aerosol components (mass, black carbon, organic carbon, water soluble particles ...) were measured. We may notice that PM measured for all the sites is generally higher than WHO norms. Organic carbon and dust particles are the two more important contributors for the ultra-fine and fine particle sizes with more organic carbon in Abidjan and dust particles in Cotonou respectively. In terms of in vitro biological studies on sampled aerosols on these sites, size-fractionated PM from the different sampling sites were compared for their ability to induce a proinflammatory response characterized by the release of the cytokine IL-6 by human bronchial epithelial cells. PM from waste burning site did not induce significant IL-6 release whatever the size fraction whereas PM from domestic fire were the most reactive especially the ultra-fine fraction. Ultra-fine particles from traffic (Abidjan and Cotonou) always induced a dose-dependent IL-6 release. A tentative cross-analysis between

School-based HIV/AIDS science education has the potential to impact students when integrated into the science curriculum. However, this mixed method study shows that school-based HIV/AIDS science education is often not infused into career subjects such as science education but integrated into civics education and taught by teachers who lack the skills, knowledge, and the training in the delivery of effective school HIV/AIDS education. Since science is where biological events take place, it is suggested that HIV/AIDS science merits being taught in the science education classroom. This study took place in nine public middle schools within two school districts in Abidjan, Ivory Coast, one major urban city in the southern region. The study utilized triangulation of multiple data sources---both qualitative and quantitative. To substantiate the claims made in this study, a range of qualitative methods such as field notes and individual interviews with 39 teachers, 63 sixth grade students, 8 school administrators, and 20 community elders were used. For the quantitative portion 140 teachers and 3510 sixth grade students were surveyed. The findings from the study prioritize science education that includes HIV/AIDS science education for all, with emphasis on HIV/AIDS prevention in Ivory Coast. The factors that influence the implementation of HIV/AIDS curricula within the Ivorian sixth grade classrooms are discussed. Interview and survey data from students, teachers, school administrators, and community elders indicate that in the Ivorian school setting, "gerontocratic" cultural influences, religious beliefs, personal cultural beliefs, and time spent toward the discourse on HIV/AIDS have led to HIV/AIDS education that is often insufficient to change either misconceptions about HIV/AIDS or risky practices. It was also found that approaches to teaching HIV/AIDS does not connect with youth cultures. By reframing and integrating current HIV/AIDS curricula into the science

Fossil fuel and biofuel emissions of gases and particles in Africa are expected to significantly increase in the near future, particularly due to the growth of African cities. In addition, African large savannah fires occur each year during the dry season, mainly for socio-economical purposes. In this study, we will present the most recent developments of African anthropogenic combustion emission inventories, stressing African specificities. (1)A regional fossil fuel and biofuel inventory for gases and particulates will be presented for Africa at a resolution of 0.25° x 0.25° from 1990 to 2012. For this purpose, the original database of Liousse et al. (2014) has been used after modification for emission factors and for updated regional fuel consumption including new emitter categories (waste burning, flaring) and new activity sectors (i.e. disaggregation of transport into sub-sectors including two wheel ). In terms of emission factors, new measured values will be presented and compared to litterature with a focus on aerosols. They result from measurement campaigns organized in the frame of DACCIWA European program for each kind of African specific anthropogenic sources in 2015, in Abidjan (Ivory Coast), Cotonou (Benin) and in Laboratoire d'Aérologie combustion chamber. Finally, a more detailed spatial distribution of emissions will be proposed at a country level to better take into account road distributions and population densities. (2) Large uncertainties still remain in biomass burning emission inventories estimates, especially over Africa between different datasets such as GFED and AMMABB. Sensitivity tests will be presented to investigate uncertainties in the emission inventories, applying methodologies used for AMMABB and GFED inventories respectively. Then, the relative importance of each sources (fossil fuel, biofuel and biomass burning inventories) on the budgets of carbon monoxide, nitrogen oxides, sulfur dioxide, black and organic carbon, and volatile

The Western clawed frog, Xenopus tropicalis, is a highly promising model amphibian, especially in developmental and physiological research, and as a tool for understanding disease. It was originally found in the West African rainforest belt, and was introduced to the research community in the 1990s. The major strains thus far known include the Nigerian and Ivory Coast strains. However, due to its short history as an experimental animal, the genetic relationship among the various strains has not yet been clarified, and establishment of inbred strains has not yet been achieved. Since 2003 the Institute for Amphibian Biology (IAB), Hiroshima University has maintained stocks of multiple X. tropicalis strains and conducted consecutive breeding as part of the National BioResource Project. In the present study we investigated the inbreeding ratio and genetic relationship of four inbred strains at IAB, as well as stocks from other institutions, using highly polymorphic microsatellite markers and mitochondrial haplotypes. Our results show successive reduction of heterozygosity in the genome of the IAB inbred strains. The Ivory Coast strains clearly differed from the Nigerian strains genetically, and three subgroups were identified within both the Nigerian and Ivory Coast strains. It is noteworthy that the Ivory Coast strains have an evolutionary divergent genetic background. Our results serve as a guide for the most effective use of X. tropicalis strains, and the long-term maintenance of multiple strains will contribute to further research efforts. PMID:26222540

The deep penetration of mobile phones offers cities the ability to opportunistically monitor citizens' mobility and use data-driven insights to better plan and manage services. With large scale data on mobility patterns, operators can move away from the costly, mostly survey based, transportation planning processes, to a more data-centric view, that places the instrumented user at the center of development. In this framework, using mobile phone data to perform transit analysis and optimization represents a new frontier with significant societal impact, especially in developing countries. In this paper we present AllAboard, an intelligent tool that analyses cellphone data to help city authorities in visually exploring urban mobility and optimizing public transport. This is performed within a self contained tool, as opposed to the current solutions which rely on a combination of several distinct tools for analysis, reporting, optimisation and planning. An interactive user interface allows transit operators to visually explore the travel demand in both space and time, correlate it with the transit network, and evaluate the quality of service that a transit network provides to the citizens at very fine grain. Operators can visually test scenarios for transit network improvements, and compare the expected impact on the travellers' experience. The system has been tested using real telecommunication data for the city of Abidjan, Ivory Coast, and evaluated from a data mining, optimisation and user prospective.
Usefulness of routine preoperative testing in a developing country: a prospective study

Introduction The assessment of anesthetic risks is an essential component of preoperative evaluation. In developing world, preanesthesia evaluation may be challenging because patient's medical history and records are scare, and language barrier limits physical examination. Our objective was to evaluate the impact of routine preoperative testing in a low-resources setting. Methods Prospective observational study performed in a French forward surgical unit in Abidjan, Ivory Coast. 201 patients who were scheduled for non urgent surgery were screened with routine laboratory exams during preoperative evaluation. Changes in surgery were assessed (delayed or scheduled). Results Abnormal hemoglobin findings were reported in 35% of patients, abnormal WBC count in 11,1% of patients, abnormal platelets in 15,3% of patients. Positive HIV results were found in 8,3% of cases. Routine tests represented 43,6% of changes causes. Conclusion Our study showed that in a developing country, routine preoperative tests showed abnormal results up to 35% of cases, and represented 43,5% of delayed surgery causes. The rate of tests leading to management changes varied widely, from 0% to 8,3%. These results suggested that selected tests would be useful to diagnose diseases that required treatment before non urgent surgery. However, larger studies are needeed to evaluate the cost/benefit ratio and the clinical impact of such a strategy. PMID:26516395

Twenty two distinct bacteriophages were isolated from sewage water from five locations in the city of Abidjan, Côte d'Ivoire over a two-year period, using a collection of Pseudomonas aeruginosa strains with diverse genotypes. The phages were characterized by their virulence spectrum on a panel of selected P. aeruginosa strains from cystic fibrosis patients and by whole genome sequencing. Twelve virions representing the observed diversity were visualised by electron microscopy. The combined observations showed that 17 phages, distributed into seven genera, were virulent, and that five phages were related to temperate phages belonging to three genera. Some showed similarity with known phages only at the protein level. The vast majority of the genetic variations among virulent phages from the same genus resulted from seemingly non-random horizontal transfer events, inside a population of P. aeruginosa phages with limited diversity. This suggests the existence of a single environmental reservoir or ecotype in which continuous selection is taking place. In contrast, mostly point mutations were observed among phages potentially capable of lysogenisation. This is the first study of P. aeruginosa phage diversity in an African city and it shows that a large variety of phage species can be recovered in a limited geographical site at least when different bacterial strains are used. The relative temporal and spatial stability of the Abidjan phage population might reflect equilibrium in the microbial community from which they are released. PMID:26115051

Assigning African elephant DNA to geographic region of origin: Applications to the ivory trade
Wasser, Samuel K.; Shedlock, Andrew M.; Comstock, Kenine; Ostrander, Elaine A.; Mutayoba, Benezeth; Stephens, Matthew
2004-01-01
Resurgence of illicit trade in African elephant ivory is placing the elephant at renewed risk. Regulation of this trade could be vastly improved by the ability to verify the geographic origin of tusks. We address this need by developing a combined genetic and statistical method to determine the origin of poached ivory. Our statistical approach exploits a smoothing method to estimate geographic-specific allele frequencies over the entire African elephants' range for 16 microsatellite loci, using 315 tissue and 84 scat samples from forest (Loxodonta africana cyclotis) and savannah (Loxodonta africana africana) elephants at 28 locations. These geographic-specific allele frequency estimates are used to infer the geographic origin of DNA samples, such as could be obtained from tusks of unknown origin. We demonstrate that our method alleviates several problems associated with standard assignment methods in this context, and the absolute accuracy of our method is high. Continent-wide, 50% of samples were located within 500 km, and 80% within 932 km of their actual place of origin. Accuracy varied by region (median accuracies: West Africa, 135 km; Central Savannah, 286 km; Central Forest, 411 km; South, 535 km; and East, 697 km). In some cases, allele frequencies vary considerably over small geographic regions, making much finer discriminations possible and suggesting that resolution could be further improved by collection of samples from locations not represented in our study.

OBJECTIVE: To demonstrate the feasibility, from the public health standpoint, of preventing mother-to-child transmission of human immunodeficiency virus type 1 (HIV-1) in Africa. METHODS: Voluntary counselling and HIV serotesting were routinely provided in four health centres in Abidjan, Côte d'Ivoire, for six months in 1998-99. Peripartum treatment with zidovudine and alternatives to breastfeeding were provided free to HIV-infected women. FINDINGS: Of the 4309 pregnant women in the study who attended their first antenatal care visit, 3756 benefited from individual counselling and pretesting (87.2%), and 3452 (80.1%) agreed to undergo HIV serotesting. Overall HIV prevalence was (12.89%) and 5% for women aged under 18 years. Among the 2998 HIV-negative women, 71% returned for their test result, whereas only 60% of the 445 HIV-positive women did so. A total of 124 HIV-positive women were informed of their serostatus and the possibility of preventing mother-to-child transmission of HIV; 100 started treatment and 80 completed zidovudine prophylaxis. At 6 weeks of age, 36 of the 78 liveborn children were being breastfed (46%), two were being mixed-fed and 41 (52%) were being artificially fed. CONCLUSIONS: In Abidjan, voluntary counselling and HIV testing with a view to preventing mother-to-child transmission was feasible in antenatal care units and was well accepted by pregnant women. An insufficient proportion of women returned to obtain their test results. This was especially so among HIV-positive women, the target group for preventing mother-to-child transmission of HIV. Additional staff were required in order to offer voluntary counselling and HIV testing to the study women. Close supervision and strong commitment of health workers were essential. Alternatives to breastfeeding were effectively proposed to HIV-positive women, with active follow-up of children and clinical, nutritional and social support. PMID:11477967

Atmospheric aerosols were sampled on filters to the air near ground level over the Ivory Coast and the Gulf of Guinea. Several elements were measured of filters by neutron activation and gamma spectrometry. Correlation thats applied to these elements allow them to be classified in groups of common origin. Study of the sampling collected over the Ivory Coast, along a''North- South'' axis, showed an increase of the concentrations of the terrestrial elements, as one passes from the coast to the north of the country. However, no particular increase of the concentrations was observed, to ground level air, when passing frommore » one side of the intertropical front to the other. In the air above the land, concentrations of marine aerosols decrease from the coast forth, especially near it. Daily variations may be noticed for all the elements The experiments performed in marthe atmosphere, over the Guif of Guinea, show that a high number of the elements measured are of terrestrial origin.

To evaluate the attitude of pregnant women towards HIV testing in two cities of West Africa: Abidjan, Côte d'Ivoire and Bobo-Dioulasso, Burkina Faso. In the context of a clinical trial to prevent HIV vertical transmission, HIV counselling and testing was offered systematically to women attending antenatal clinics. Informed consent was obtained and test results were given anonymously. Multiple logistic regression was performed to identify factors associated with refusal for testing and failure to return for test results. A total of 9724 pregnant women were interviewed from January 1995 to September 1996. In Abidjan (n=5766) and Bobo-Dioulasso (n=3958), 78 and 92.4% of the women consented to HIV testing, respectively, and 58.4 and 81.8% of them returned for the test results disclosure, respectively. In the two sites, the counsellors themselves and high educational level of the women appeared to be related to refusal of the test, whereas last trimester gestation was associated with failure to return for test results. In Abidjan, foreigners and employees were more likely to refuse testing, and HIV-infected women were three times less likely to return for results than uninfected women. Future implementation of interventions to reduce vertical transmission of HIV that require antenatal HIV testing and counselling will have to solve issue of acceptability of HIV testing by pregnant women.

Rapid urbanization is a key driver of the unique set of health risks facing urban populations. One of the most critical health hazards facing urban women is intimate partner violence (IPV). In post-conflict urban areas, women may face an even greater risk of IPV. Yet, few studies have examined the IPV experiences of urban-dwelling, conflict-affected women, including those who have been internally displaced. This study qualitatively examined the social and structural characteristics of the urban environment that contributed to the IPV experiences of women residing in post-conflict Abidjan, Côte d'Ivoire. Ten focus groups were conducted with men and women, both internally displaced (IDPs) and non-displaced. Lack of support networks, changing gender roles, and tensions between traditional gender norms and those of the "modern" city were reported as key contributors to IPV. Urban poverty and with it unemployment, food insecurity, and housing instability also played a role. Finally, IDPs faced heightened vulnerability to IPV as a result of displacement and discrimination. The relationship between economic strains and IPV are similar to other conflict-affected settings, but Abidjan's urban environment presented other unique characteristics contributing to IPV. Understanding these factors is crucial to designing appropriate services for women and for implementing IPV reduction interventions in urban areas. Strengthening formal and informal mechanisms for help-seeking, utilizing multi-modal interventions that address economic stress and challenge inequitable gender norms, as well as tailoring programs specifically for IDPs, are some considerations for IPV program planning focused on conflict-affected women in urban areas.

A cost effectiveness study was conducted with the main objective to assess the operational costs of a vaccination campaign against yellow fever organised and implemented in Abidjan from September 21st to October 2nd, 2001. The study was carried out from the perspective of the health authorities. Data was collected retrospectively on all information related to resources needed and required activities. The justification of the monetary value of resources was provided with written proof and receipts as well as other supporting documents. The coverage achieved was 91.33% with 2 584 360 doses of vaccine having been administered. Spending on vaccines and vaccine supplies amounted to 1 123 177 128 FCFA; the average cost per dose was 539.40 FCFA. Human resource costs amounted to 2590 people who were mobilized for a total cost of 125 678 400 FCFA. The total operational cost of the vaccination campaign was 1 394 010 829 FCFA. Vaccines and supplies were the largest item of expenditure, or 80.57% of the total spent. The results of this study could serve as a tool for decision-making related to funding a vaccination campaign. Taking account of these results could contribute to the development of strategies to effectively reduce the operational cost of a vaccination campaign.

A child's multiple disabilities have a major impact on families in both developed and developing countries. In Côte d'Ivoire, very few data are available concerning the real experiences of families of children with multiple disabilities. The objective of this study was to improve our knowledge of the impact of children with multiple disabilities on families in Côte d'Ivoire. A qualitative study was conducted among the families consulting the Child Guidance Centre of the National Institute of Public Health in Abidjan. Data were collected in May 2015 by semi-structured individual interviews with mothers of children with multiple disabilities. Twenty mothers of multiply disabled children between the ages of 2 and 14 years were interviewed. The child's multiple disability was found to have a negative impact on finances, health, and social life. Health check-ups, treatment and transport are the main additional costs. Mothers suffer from insomnia, fatigue, back pain and anxiety and were often held responsible for their child's disability. A disabled child was a source of discord in several couples and a cause of school drop-out in some families.This study partially addresses the experiences of families with children with multiple disabilities. It confirms the results of several other studies, highlighting the vulnerability and social dysfunction of these families. The presence of a child with multiple disabilities in a family is a source of psychological, financial and social upheaval. This study raises questions about the impact of multiple disabilities on the whole family and a more detailed analysis of economic aspects.

Men who have sex with men (MSM) are at high risk of HIV. Few data are available on MSM and HIV-related risk behaviors in West Africa. We aimed to describe risk behaviors and vulnerability among MSM in Abidjan, Cote d′Ivoire. We conducted a cross-sectional respondent-driven sampling survey with 601 MSM in 2011–2012. Sociodemographic and behavioural data as well as data related to emotional state and stigma were collected. Population estimates with 95% confidence intervals were produced. Survey weighted logistic regression was used to assess factors associated with inconsistent condom use in the prior 12 months. Most MSM were 24 years of age or younger (63.9%) and had attained at least primary education (84.4%). HIV risk behaviors such as low condom and water-based lubricant use, high numbers of male and female sex partners, and sex work were frequently reported as well as verbal, physical and sexual abuse. Inconsistent condom use during anal sex with a male partner in the prior 12 months was reported by 66.0% of the MSM and was positively associated with history of forced sex, alcohol consumption, having a regular partner and a casual partner, having bought sex, and self-perception of low HIV risk. MSM in Abidjan exhibit multiple and frequent HIV-related risk behaviors. To address those behaviours, a combination of individual but also structural interventions will be needed given the context of stigma, homophobia and violence. PMID:24959923

Poaching of elephants is now occurring at rates that threaten African populations with extinction. Identifying the number and location of Africa’s major poaching hotspots may assist efforts to end poaching and facilitate recovery of elephant populations. We genetically assign origin to 28 large ivory seizures (≥0.5 metric tons) made between 1996 and 2014, also testing assignment accuracy. Results suggest that the major poaching hotspots in Africa may be currently concentrated in as few as two areas. Increasing law enforcement in these two hotspots could help curtail future elephant losses across Africa and disrupt this organized transnational crime. PMID:26089357

Ochratoxin A (OTA) is a mycotoxin produced mostly by several species of Aspergillus and Penicillium. OTA is nephrotoxic in all animal species in which it has been tested and is cancerogenic in rodents. It is associated with Balkan endemic nephropathy. It is naturally present in many crop products such as cereals (barley, wheat, maize) and dried fruits, spices, coffee, wine, olives, and cocoa. The aim of this study was to assess the contamination of three Ivoirian spices with OTA (ginger, chili, and pepper) widely consumed by the population. A total of 90 spice samples (ginger: n = 30; chili: n = 30; pepper n = 30) was taken from various sales outlets of Abidjan. OTA was quantified using an HPLC apparatus coupled with a fluorimetric detector. The chili and ginger samples were contaminated with OTA at a mean concentration of 57.48 ± 174 and 0.12 ± 0.15 μg/kg, respectively. No contamination of the pepper samples was detected. Eight (26.67 %) of the chili samples exceeded the maximum limit of 15 μg/kg established by European regulation. These results should serve as an alert on the risk to the consumer population of these products that are highly contaminated with OTA.

This work is part of the DACCIWA FP7 project (Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa) in the framework of the Work Package 2 Air Pollution and Health
. This study aims to characterize urban air pollution levels through the measurement of NO2, SO2, NH3, HNO3 and O3 in Abidjan, the economic capital of Côte d'Ivoire. Measurements of inorganic gaseous pollutants, i.e. NO2, SO2, NH3, HNO3 and O3 were performed in Abidjan during an intensive campaign within the dry season (15 December 2015 to 16 February 2016), using INDAAF (International Network to study Deposition and Atmospheric chemistry in AFrica) passive samplers exposed in duplicate for 2-week periods. Twenty-one sites were selected in the district of Abidjan to be representative of various anthropogenic and natural sources of air pollution in the city. Results from this intensive campaign show that gas concentrations are strongly linked to surrounding pollution sources and show a high spatial variability. Also, NH3, NO2 and O3 gases were present at relatively higher concentrations at all the sites. NH3 average concentrations varied between 9.1 ± 1.7 ppb at a suburban site and 102.1 ± 9.1 ppb at a domestic fires site. NO2 mean concentration varied from 2.7 ± 0.1 ppb at a suburban site to 25.0 ± 1.7 ppb at an industrial site. Moreover, we measured the highest O3 concentration at the two coastal sites of Gonzagueville and Félix-Houphouët-Boigny International Airport located in the southeast of the city, with average concentrations of 19.1 ± 1.7 and 18.8 ± 3.0 ppb, respectively. The SO2 average concentration never exceeded 7.2 ± 1.2 ppb over all the sites, with 71.5 % of the sampling sites showing concentrations ranging between 0.4 and 1.9 ppb. The HNO3 average concentration ranged between 0.2 and 1.4 ppb. All these results were combined with meteorological parameters to provide the first mapping of gaseous pollutants on the scale of the district of Abidjan using geostatistical

In April 2008, Abidjan was again faced with another case of yellow fever after the epidemic of 2001 causing mass immunization campaign. In order to evaluate the extent of amaril virus circulation and the risk for local people, an entomological investigation was carried out by the Ministry of Health and Public Hygiene of Côte d'Ivoire. At "Entent" area of Treichville, Breteau index was estimated at 34, recipient index at 20% and house index at 25%. Those indexes were respectively 53, 21 and 31% at "Vridi canal" of Port Bouet. In the both neighborhood, Aedes aegypti accounted for more than 80% of mosquitoes caught and more than 90% of mosquitoes adults obtained from larval breeding. This new situation of epidemic risk could be explained by several factors including the reception of 70% of forced migration people caused by the crisis in the country occurred in 2002, the probable drop of preventive immunization, the environment deterioration creating of more breeding sites of Ae. aegypti.

Objectives To assess condom use and prevalence of sexually transmitted infections (STI) and HIV among male sex workers (MSW) in Abidjan, Côte d'Ivoire. Methods A cross-sectional survey was conducted between October 2007 and January 2008 among MSW attending a sex worker clinic in Abidjan. A short questionnaire was administered in a face-to-face interview, and the participants were asked to provide a urine sample for STI testing and to self-collect transudate of the gingival mucosa for anonymous HIV testing, using a rapid test. A rectal swab for STI testing was taken by a physician. Molecular amplification assays were performed for the detection of Chlamydia trachomatis, Neisseria gonorrhoeae and Trichomonas vaginalis. Results 96 MSW participated in the survey, their median age was 27 years and the median duration of sex work was 5 years. Consistent condom use with clients during the last working day was 86.0%, and consistent condom use with the regular partner during the last week was 81.6%. HIV infection was detected in 50.0% of the participants. The prevalence of N gonorrhoeae was 12.8%, chlamydia infection was present in 3.2% and T vaginalis in 2.1% of the study participants. Conclusions HIV and STI rates found in this study confirm the high risk and vulnerability status of MSW in Côte d'Ivoire. There is a definite need for studies exploring risk and risk perceptions among MSW in more depth and for services tailored to their needs, including developing and validating simple algorithms for the diagnosis of STI in MSW and men who have sex with men.

Le craton ouest-africain et le bouclier guyanais: un seul craton au Protérozoïque inférieur?

Caen-Vachette, Michelle
Geochronological and paleomagnetism data for southern West African craton and Guyana shield in South America, are concordant and suggest the existence of a large unit grouping them during Archean and Lower Proterozoic times. The paleomagnetism data allow to put on a single line, the Zednes (Mauritania), Sassandra (Ivory Coast) and Guri (Venezuela) fault zones, the mylonites of which were dated 1670 Ma. This age reflects the end of the eburnean-transamazonian shearing tectonic, which affected the large West Africa-Guyana unit. This line separates the western Archean domain from the eastern lower Proterozoic one; thence it is possible to correlate the Sasca (Ivory Coast) and Pastora (Venezuela) areas. Archean relics have been found in mobile pan-african-bresiliano zones which surround the Precambrian cratons; this fact suggests the existence of still more extended Archean craton than defined above.

Human conflict generally has substantial negative impacts on wildlife and conservation. The recent civil war (1995-2006) in the Democratic Republic of Congo (DRC) resulted in a significant loss of wildlife, including elephants, due to institutional collapse, lawlessness and unbridled exploitation of natural resources such as minerals, wood, ivory and bushmeat. We used data from distance sampling surveys conducted before and after the war in a protected forest, the Okapi Faunal Reserve, to document changes in elephant abundance and distribution. We employed Generalized Additive Models to relate changes in elephant distribution to human and environmental factors. Populations declined by nearly fifty percent coinciding with a major increase in elephant poaching as indicated by reports of ivory trade during the war. Our results suggest that humans influenced elephant distribution far more than habitat, both before and after the war, but post-war models explained more of the variation. Elephant abundance declined more, closer to the park boundary and to areas of intense human activity. After the war, elephant densities were relatively higher in the centre of the park where they were better protected, suggesting that this area may have acted as a refuge. In other sites in Eastern DRC, where no protection was provided, elephants were even more decimated. Post-war dynamics, such as weakened institutions, human movements and availability of weapons, continue to affect elephants. Survival of remaining populations and recovery will be determined by these persistent factors and by new threats associated with growing human populations and exploitation of natural resources. Prioritizing wildlife protection, curbing illegal trade in ivory and bushmeat, and strengthening national institutions and organizations in charge of conservation will be crucial to counter these threats.

Human conflict generally has substantial negative impacts on wildlife and conservation. The recent civil war (1995-2006) in the Democratic Republic of Congo (DRC) resulted in a significant loss of wildlife, including elephants, due to institutional collapse, lawlessness and unbridled exploitation of natural resources such as minerals, wood, ivory and bushmeat. We used data from distance sampling surveys conducted before and after the war in a protected forest, the Okapi Faunal Reserve, to document changes in elephant abundance and distribution. We employed Generalized Additive Models to relate changes in elephant distribution to human and environmental factors. Populations declined by nearly fifty percent coinciding with a major increase in elephant poaching as indicated by reports of ivory trade during the war. Our results suggest that humans influenced elephant distribution far more than habitat, both before and after the war, but post-war models explained more of the variation. Elephant abundance declined more, closer to the park boundary and to areas of intense human activity. After the war, elephant densities were relatively higher in the centre of the park where they were better protected, suggesting that this area may have acted as a refuge.

The high-arctic Ivory Gull (Pagophila eburnea) has recently undergone a sharp decline in numbers, and in Canada it is listed as "Endangered" under the Species-At-Risk Act. To test for circumpolar genetic distinctiveness, we examined 264 bp of the mtDNA Control Region Domain I from 127 museum specimens collected during the breeding season from northern Canada, Greenland, and Norway, and during the non-breeding season from adjacent overwintering grounds in Canada, Greenland, and a disjunct area in Alaska adjacent to the Bering Sea. Partition of genetic variance according to various phylogeographic and breeding ground models indicates no strong population structure, except that Alaska birds are consistently differentiated from other locations, and there are significant temporal shifts in haplotype frequencies. The evidence suggests that Ivory Gulls in Canada, Greenland, and Norway are a single genetic entity, in contrast to Alaska birds, which may represent a distinctive Siberian population.

Uncertain sightings and the extinction of the Ivory-billed Woodpecker.
Solow, Andrew; Smith, Woollcott; Burgman, Mark; Rout, Tracy; Wintle, Brendan; Roberts, David

The extinction of a species can be inferred from a record of its sightings. Existing methods for doing so assume that all sightings in the record are valid. Often, however, there are sightings of uncertain validity. To date, uncertain sightings have been treated in an ad hoc way, either excluding them from the record or including them as if they were certain. We developed a Bayesian method that formally accounts for such uncertain sightings. The method assumes that valid and invalid sightings follow independent Poisson processes and use noninformative prior distributions for the rate of valid sightings and for a measure of the quality of uncertain sightings. We applied the method to a recently published record of sightings of the Ivory-billed Woodpecker (Campephilus principalis). This record covers the period 1897-2010 and contains 39 sightings classified as certain and 29 classified as uncertain. The Bayes factor in favor of extinction was 4.03, which constitutes substantial support for extinction. The posterior distribution of the time of extinction has 3 main modes in 1944, 1952, and 1988. The method can be applied to sighting records of other purportedly extinct species. ©2011 Society for Conservation Biology.
Modélisation à long terme et optimisation du stock d'énergie des installations solaires autonomes

A sizing approach of storage capacity for autonomous solar system has been developed by analyzing the difference between solar radiation input and energy demand on long-term periods. This approach has been implemented using series of daily global irradiation data recorded or generated on a horizontal surface in the meteorological stations of Abidjan (Ivory Coast), Algiers and Tamanrasset (Algeria) and Carpentras (France). The obtained results show that for an energy demand equaling the pluriannual mean of solar irradiation a storage of several months is needed to obtain the autonomy of solar systems located in Algiers, Carpentras and Tamanrasset. It should be too expensive investment to set-up such solar systems in these locations. Therefore, the size of the storage is minimized by using a non-zero initial energy storage and reducing the energy demand. This procedure show that it is possible to provide every day a programmed energy using autonomous solar systems which are competitive economically. Une approche de dimensionnement de la capacité de stockage des installations solaires autonomes a été développé. Elle est basée sur l'analyse de la différence entre l'énergie incidente et la consommation requise. Cette méthode a été mise au point à partir de données journalières d'irradiation globale enregistrées ou reconstituées sur plan horizontal dans les stations météorologiques d'Abidjan (Côte d'Ivoire), d'Alger et de Tamanrasset (Algérie) et de Carpentras (France). Pour une demande énergétique correspondant à la production moyenne pluriannuelle d'énergie solaire, les résultats montrent qu'un stockage de plusieurs mois est requis pour garantir l'autonomie de fonctionnement des installations solaires implantées à Alger, Carpentras et Tamanrasset. L'autonomie ainsi obtenue n'est pas économiquement rentable. Aussi, la taille du stockage a été minimisée en utilisant un stock initial d'énergie au démarrage de l'installation et en r

HIV vulnerability and the erasure of sexual and gender diversity in Abidjan, Côte d'Ivoire.
Thomann, Matthew
2016-01-01
In the fight against concentrated HIV epidemics, men who have sex with men (MSM) are often framed as a homogeneous population, with little attention paid to sexual and gender diversity and its impact on HIV vulnerability. This article draws on ethnographic research conducted in Abidjan, Côte d'Ivoire among les branchés - a local term encompassing several categories of same-sex desire and practice. In the context of increased HIV prevention programming targeting Ivoirian sexual and gender minorities, such diversity is effectively erased. This obfuscation of difference has particularly negative impacts for travestis, who may be at higher risk for HIV infection, though research and prevention efforts in which they are grouped with 'MSM' render them underrepresented and make their vulnerability difficult to quantify. Branchés whose class and/or ethnic backgrounds compound their stigmatised status as sexual and gender minorities also bear the burden of this exclusion. Furthermore, some branchés deploy 'MSM' as a form of self-identification, further complicating who such categories represent. By highlighting the ways in which constructions of gender and sexuality within HIV/AIDS programming obscure complex social realities, I aim to reorient thinking around the development of purposeful HIV programming that engages the complexity of sexual and gender minority experience.

To update full time educated youth data on smoking prevalence related to gender and to assess perception and behaviour related to smoking, we have led a self-administrated question-study from January to June 2002 in Abidjan with students from 8 to 22 years old. Our population was divided in 3 groups: T1 (812 years), T2 (13-17 years) and T3 (18-22 years). The size of each group has been determined using the smoking estimated rate in each of them. 2742 students had returned a well-full questionnaire, with the following rates, expressed by mean and standard deviation in%: a total smoking rate at 7.9 +/- 0.5, with statistic difference between boys and girls (11 +/- 0,8 versus 3,7 +/- 0,5; p<0.001). This rate increased with age: 3.7 +/- 0.8 in T1; 12.9 +/- 1.0 in T2 and 17.1 +/- 1,1% in T3. Globally, the rate was 0.7 +/- 0.2 for regular smokers (>or=1 cigarette/day) (10% of C.D.T.) and 1.7 +/- 0.2% for ex-smokers. 99.2% of current smokers used cigarettes only. On average, the tobacco consumption was 3.4 cigarettes/day. In non-smokers group, 88% had respiratory symptoms linked to smoke exposure, with 17% of major dyspnea. Non smokers reported public places as the most frequent (66.7 +/- 1.3%) and the highest long time exposure (44.3 +/- 1.9%) places to second hand smoke. A similar smoking prevalence between asthmatics and non-asthmatics subjects, and between sporty type and non sporty type subjects, suggested that students had superficial knowledge or under assessment on smoking detrimental effect. However, their perception of smoking health hazard was sufficient to give 95 +/- 1% favourable opinions on necessary smoking place regulations and 85 +/- 1% favourable opinions on tobacco product advertising ban. The epidemiological and behaviour information given by this study might contribute to the development of a national youth tobacco control program, provided a complementary national survey would be led including non educated youth.

Violence is a human rights violation, and an important measure in understanding HIV among female sex workers (FSW). However, limited data exist regarding correlates of violence among FSW in Côte d'Ivoire. Characterizing prevalence and determinants of violence and the relationship with structural risks for HIV can inform development and implementation of comprehensive HIV prevention and treatment programs. FSW > 18 years were recruited through respondent driven sampling (RDS) in Abidjan, Côte d'Ivoire. In total, 466 participants completed a socio-behavioral questionnaire and HIV testing. Prevalence estimates of violence were calculated using crude and RDS-adjusted estimates. Relationships between structural risk factors and violence were analyzed using χ tests and multivariable logistic regression. The prevalence of physical violence was 53.6% (250/466), and sexual violence was 43.2% (201/465) among FSW in this study. Police refusal of protection was associated with physical (adjusted Odds Ratio [aOR]: 2.8; 95% confidence interval [CI]: 1.7 to 4.4) and sexual violence (aOR: 3.0; 95% CI: 1.9 to 4.8). Blackmail was associated with physical (aOR: 2.5; 95% CI: 1.5 to 4.2) and sexual violence (aOR: 2.4; 95% CI: 1.5 to 4.0). Physical violence was associated with fear (aOR: 2.2; 95% CI: 1.3 to 3.1) and avoidance of seeking health services (aOR: 2.3; 95% CI: 1.5 to 3.8). Violence is prevalent among FSW in Abidjan and associated with features of the work environment and access to care. These relationships highlight layers of rights violations affecting FSW, underscoring the need for structural interventions and policy reforms to improve work environments, and to address police harassment, stigma, and rights violations to reduce violence and improve access to HIV interventions.

To evaluate patients wearing hearing aid at the International Center of Auditory Correction in Abidjan. It is a descriptif and transversal study from 07/01/99 to 06/30/10. We have included the files of patients completely filled. We have studied the indications, prosthetics gains and the satisfaction after hearing aid. We have achieved 536 files. The average was 36 years. The indications have been in 76.1% cases of sensorineural hearing loss. The hearing loss has been associated in 13.2% cases to language disorder. For all patient we have noticed bilateral hearing loss in 496 cases (92.5%). The behind the ear aids have been chosen in 69% cases. The type was analogical or digital respectively in 65% and 35% des cas. The prosthetic pure tonal gain was more than 30 dB in 66.8% cases and the prosthetic speech reception threshold gain more than 30 dB in 55.3% cases. The patients have been respectively satisfied less satisfacted, no satisfacted in 68.47%, 22.76% and 8.7% cases. The hearing aids have improved the audition in most of the indications. The proportion of patients satisfied was proportionally equivalent to the audiometric results.

Poor micronutrient intakes are a major contributing factor to the high burden of micronutrient deficiencies in Côte d’Ivoire. Large-scale food fortification is considered a cost-effective approach to deliver micronutrients, and fortification of salt (iodine), wheat flour (iron and folic acid), and vegetable oil (vitamin A) is mandatory in Côte d’Ivoire. A cross-sectional survey on households with at least one child 6–23 months was conducted to update coverage figures with adequately fortified food vehicles in Abidjan, the capital of and largest urban community in Côte d’Ivoire, and to evaluate whether additional iron and vitamin A intake is sufficient to bear the potential to reduce micronutrient malnutrition. Information on demographics and food consumption was collected, along with samples of salt and oil. Wheat flour was sampled from bakeries and retailers residing in the selected clusters. In Abidjan, 86% and 97% of salt and vegetable oil samples, respectively, were adequately fortified, while only 32% of wheat flour samples were adequately fortified, but all samples contained some added iron. There were no major differences in additional vitamin A and iron intake between poor and non-poor households. For vitamin A in oil, the additional percentage of the recommended nutrient intake was 27% and 40% for children 6–23 months and women of reproductive age, respectively, while for iron from wheat flour, only 13% and 19% could be covered. Compared to previous estimates, coverage has remained stable for salt and wheat flour, but improved for vegetable oil. Fortification of vegetable oil clearly provides a meaningful additional amount of vitamin A. This is not currently the case for iron, due to the low fortification levels. Iron levels in wheat flour should be increased and monitored, and additional vehicles should be explored to add iron to the Ivorian diet. PMID:27384762

In Côte d'Ivoire, the prevalence of malnutrition among children younger than 5 years exceeded 5% in 2011 and was thus considered serious. This overall prevalence may nonetheless mask differences and specificities between regions and municipalities. This study sought to determine the prevalence and risk factors of malnutrition among children in this age group in a semi-urban area of Abidjan. This exhaustive, descriptive, cross-sectional survey took place from May 6 to July 31, 2010. The children's nutritional status was determined according to the WHO criteria. Univariate and multivariate analysis of factors associated with malnutrition (social and demographic characteristics, immunization status, children's eating practices, and household characteristics) were studied. We visited 668 households and recruited 809 children. The prevalence of malnutrition was 22.5%. Multivariate analysis showed that the introduction of porridge after 6 months halved the risk of malnutrition. Risk tripled for children whose father's occupation did not guarantee a regular income. Among the factors highlighted by this study, dietary practices seem the most amenable to corrective action. For example, the adoption of outreach programs by the Maternal and Child Protection services could improve nutritional practices in households.

Nearly half of the total area of the Republic of Ghana is covered by sedimentary rocks. These rocks are found mainly in four different parts of the country: Tano basin, Keta basin, Voltaian basin, and the continental shelf. Because oil seeps in saturated superficial sands were found in the Tano basin, efforts to find oil in Ghana started as far back as 1896 in this basin, which is located at the extreme southwestern part of Ghana and has an area of 1165 km/sup 2/ (450 mi/sup 2/). The Keta basin, located at the extreme southeastern part of Ghana, has anmore » area of 2200 km/sup 2/ (850 mi/sup 2/). The continental shelf of Ghana is at the southern part of the country and has an area of 27,562 km/sup 2/ (10,640 mi/sup 2/). The possibility of finding oil and/or gas at the extreme western part of the continental shelf cannot be overemphasized. The expansive Voltaian sedimentary basin, located in the central part of Ghana, covers an area of about 103,600 km/sup 2/ (40,000 mi/sup 2/). Although no trace of hydrocarbon was found in the only well that has been drilled so far in this basin, the presence of traces of bitumen in some parts of the basin indicates that, despite of its age, the basin might prove to be an oil province. The recent discovery of oil in the Ivory Coast means that it is possible to find oil or gas in Ghana, inasmuch as Ghana's petroleum potential is closely associated with that of the Ivory Coast basin, which extends for 560 km (300 mi) along the entire Ivory Coast and persists eastward into Ghana for an additional 320 km (200 mi), terminating in the area directly west of Accra.« less

The thermal resource off the Ivory Coast is quite good for OTEC purposes. There are consistently large ..delta..T (surface temperature--temperature at depth) values throughout the year. The mean ..delta..T at 1000 meters is approximately 22/sup 0/C. A mean annual ..delta..T of 20/sup 0/C can be reached at a depth of only 600 meters. The thermal resource for the coldest month of the year is also adequate at 600 meters. Water 1000 meters deep is available within 35 kilometers from the shore. The waters south of the Ivory Coast do not have a particularly good mixed layer depth. Strong winds andmore » tropical storms are a rare occurrence. Similarly, the sea and swell conditions do not present a problem for OTEC development in this area. Currents are generally moderate, although occasional periods of weak currents less than 1/4 knot can be expected. The consistently large thermal resource without major environmental problems recommends this location as a potential OTEC site.« less

A prospective study was carried out from 2010 to 2012 at the Hôpital Général d'Abobo (HGA) in Abidjan, in order to determine the impact of infectious and parasitic diseases on child cognitive development. Blood samples were examined by means of thick drop and blood smear; as for stool by direct examination and concentration by formalin-ether method. We evaluated the prevalence, the parasite load of malaria and gastrointestinal parasites; then we investigated the risk factors for these disorders. Overall, 331 pregnant women in the last trimester of their pregnancy were enrolled. The plasmodic index was 3.9% with infestation specific rates of P. falciparum from 100%. Concerning digestive protozoa, it has been observed 71.3% of nonpathogenic, against 9.7 % of pathogens, either an overall prevalence of 51.4% of digestive parasites. The calculated average parasitic loads revealed 3089.2 tpz/μl of blood (95 % CI: 591.1-5587.3) for malaria, 6.5 eggs per gram of stool (95 % CI: 0.4-13.4) for intestinal helminths and one parasite by microscopic field for protozoa (common infestation). It has been shown that the occurrence of malaria has been linked to the non-use of impregnated mosquito nets (x 2 = 0.012; p = 0.018), not to age. No link could be established between the presence of digestive parasites and the age of pregnant women, or socioeconomic conditions (level of education, profession, type of toilet). Malaria is less common in pregnant women while the rate of digestive parasites remains high.

We studied the frequency of documentation of disclosure of HIV status in medical charts and its correlates among HIV-infected adolescents in 2009, in Abidjan, Côte d'Ivoire. The PRADO-CI is a cross-sectional study aimed at studying HIV-infected adolescents' social, psychological, and behavioural difficulties and their determinants in Abidjan, Côte d'Ivoire. In this study, we present specific analyses on disclosure. All HIV-infected adolescents aged 13-21 years and followed at least once in 2009 in two urban HIV-care centres in Abidjan (Cepref and Yopougon Teaching Hospital) were enrolled in the study. Standardized data were extracted from medical records to document if there was notification of disclosure of HIV status in the medical record. Frequency of notification of HIV disclosure was estimated with its 95% confidence interval (CI) and correlates were analyzed using logistic regression. In 2009, 229 adolescents were included: 126 (55%) males; 93% on antiretroviral therapy (ART), 61% on cotrimoxazole prophylaxis. Their median age was 15 years at the time of the study. Among the 193 patients for whom information on HIV status disclosure was documented (84%), only 63 (32.6%; 95% CI=26.0-39.3%) were informed of their status. The proportion of adolescents informed increased significantly with age: 19% for 13-15 years, 33% for 16-18 years and 86% for 19-21 years (p <0.0001). Adolescents on ART tended to be more likely to be informed of their HIV status (34.5%) than those not treated (13.3%) (p=0.11). Those on cotrimoxazole were significantly more likely to be informed (39.6%) than those not (21.9%) (p=0.01). Disclosure was significantly higher in adolescents with a history of ART regimen change (p=0.003) and in those followed in the Cepref (48.4%) compared to the Yopougon Teaching Hospital (24.8%), (p=0.001). In multivariate analyses, disclosed HIV status was significantly higher in those followed-up in the Cepref compared to the other centre: adjusted odds ratio

This image of Antarctica shows the Bryan Coast (lower left), the English Coast (lower central), Alexander Island (middle right), the Fallieres Coast (top right), and the Bellingshausen Sea. The entire continent has been dedicated to peaceful scientific investigation since 1961, with the signing of the Antarctic Treaty.The waters surrounding Antarctica are intensely cold. Salt water freezes at -2C, allowing sea ice to form. The middle left portion of the image shows quite a lot of sea ice in the Bellingshausen Sea. During the Antarctic winter, when data for this image was acquired, Antarctica doubles in size to about 28.5 million square km (or about 11 million square miles), and temperatures in the -60C range are common.This true-color image was compiled from MODIS data gathered March 29, 2002.

The authors used computed tomography (CT) to assess and categorize the topography of ischemic strokes (IS) among blacks living in Abidjan, the commercial and administrative center of Côte d'Ivoire, in West Africa. This retrospective study analyzed CT data of patients admitted to the Sainte Anne Marie Polyclinic (the principal private hospital in the country) and to the neurology department of the university hospital center in Cocody, from January 1, 2000, to December 31, 2001. The study included patients who met World Health Organisation criteria for stroke and had CT performed during the hospitalization for this stroke. We examined CT data to find early and late signs of IS, analyze lesion diameter (15 mm cutoff used to distinguish infarcts from lacuna), and determine their topography (cerebral arterial territory and localization, that is, brain lobes, basal ganglia and posterior cerebral fossa). We included 260 subjects (58% males) with a median age of 45 years (range: 20-80 years). CT findings were abnormal for 224 patients with infarcts (72.7%), lacuna (27.3%), or both (8%). As reported elsewhere, the anterior arterial territory was most often affected (83.9%) with a middle cerebral artery lesion in 79.4% of patients. Posterior territory (16.1%) lesions and lacuna were probably underestimated because CT exploration is reported to be less useful for this area than for the carotid area. On the other hand, CT diagnoses infarcts more easily than it does lacuna. CT was normal for 36 patients although performed no more than 3 days after IS. These patients did not undergo CT angiography, which might have shown cerebral artery occlusion. Our study included IS of all types and typography. Stroke registries in Africa would provide useful data for better assessment of prevalence for specific topographic and etiologic types of stroke.

On August 2006, a cargo ship illegally dumped 500 t of toxic waste containing high concentrations of hydrogen sulphide in numerous sites across Abidjan. Thousands of people became ill. Seventeen deaths were associated with toxic waste exposure. This study reports on environmental and health problems associated with the incident. A cross-sectional transect study was conducted in five waste dumping site areas. Of the households, 62.1% (n = 502) were exposed to the effects of the pollutants and 51.1% of the interviewed people (n = 2,368) in these households showed signs of poisoning. Most important symptoms were cough (37.1%), asthenia (33.1%), pruritus (29.9%) and nausea (29.1%). The health effects showed different frequencies in the five waste impact sites. Among the poisoned persons, 21.1% (n = 532) presented symptoms on the survey day (i.e., 4 months after incident). Transect sampling allowed to determine a radius of vulnerability to exposure of up to 3 km from the point of toxic waste disposal. The area of higher vulnerability is influenced by various environmental factors, such as size and severity of pollution site, duration of toxic waste pollution on the impact site and locally climatic conditions. The surveillance of effects on environment and human health is warranted to monitor the development.

The Republic on the Ivory Coast in Africa is profiled in a Dec. 1987 publication of the U.S. State Department. The geography of the country is described as generally flat, with dense forests in the west, scrub savannah stretching in a narrow strip along the coast midway to Ghana, and a tropical forest and a savannah lying inland. A brief history of the country prior to and during its experience as a French colony is also included. The country's 1986 population of 10.2 million contains more than 60 ethnic groups; literacy rate is 35%, life expectancy is 52 years, and the 1983 infant mortality rate was 121/1,000. Per capita income in 1986 was $921. Petroleum is a natural resource but thus far its exploitation has been financially disappointing. Agriculture produces 25% of the country's gross domestic product, while the food, processing, and textile industries produce 20%. Political conditions have been relatively stable since the Ivory Coast gained its independence from France in 1960. The publication also describes the country's government structure, political conditions, national defense system, and foreign relations policy. It includes general information for travelers to the country and lists principal government officials and U.S. officials to the country as of date of the publication. A bibliography and map are also provided.

Hepatitis B and HIV infection are two viral infections that represent real global public health problems. In order to improve their management, some hypotheses suggest that genetic predispositions like ABO and Rh blood groups would influence the occurrence of these diseases. The aim of the present study was to examine the association between ABO and Rhesus blood groups and the susceptibility to HIV infection and hepatitis B. We conducted a cross-sectional and analytical study in a population of voluntary blood donors in the Blood Transfusion Center of Abidjan. All blood donors who donated blood between January and June 2014 were tested for HBs antigen and anti-HIV antibodies (ELISA tests) and were ABO typed. The total number of examined blood donors during this period was 45,538, of which 0.32% and 8.07% were respectively infected with HIV and hepatitis B virus. O-group donors were more infected than non-O donors. Our study is an outline concerning the search for a link between ABO and Rh blood groups and hepatitis B and HIV infection. Further studies should be conducted to confirm the interaction between these two infections and contribute to the search for new therapeutic approaches.

Patent ductus arteriosus surgery is well documented. Hospital Mortality has reduced to almost 0%. Yet, with adults, this surgical cure is likely to be difficult and require some technical skills A retrospective study of surgical procedures and results after surgery of patent ductus arteriosus (PDA) in adults. Since 1978 to 2000 we have reported 16 operated cases. The average age was 22.5 years. There was female predominance with a sex ratio of 2.3/1. All patent ductus arteriosus had been confirmed by two dimensional echocardiography (2D echocardiography) and cardiac catheterization. All hemodynamic types of Nadas classification were observed. Double or triple ligation supported on Teflon felt was the most frequent technique used (69%). This technique gave good results in view of the absence of hospital mortality and only 1 case of recanalisation after a long follow up of all patients from 1 - 7 years (mean 5 years). Double or triple ligation on Teflon felt according to Wright technique is a good technique.

In late 1994 and early 1995, Ebola (EBO) virus dramatically reemerged in Africa, causing human disease in the Ivory Coast and Zaire. Analysis of the entire glycoprotein genes of these viruses and those of other EBO virus subtypes has shown that the virion glycoprotein (130 kDa) is encoded in two reading frames, which are linked by transcriptional editing. This editing results in the addition of an extra nontemplated adenosine within a run of seven adenosines near the middle of the coding region. The primary gene product is a smaller (50-70 kDa), nonstructural, secreted glycoprotein, which is produced in large amounts and has an unknown function. Phylogenetic analysis indicates that EBO virus subtypes are genetically diverse and that the recent Ivory Coast isolate represents a new (fourth) subtype of EBO virus. In contrast, the EBO virus isolate from the 1995 outbreak in Kikwit, Zaire, is virtually identical to the virus that caused a similar epidemic in Yambuku, Zaire, almost 20 years earlier. This genetic stability may indicate that EBO viruses have coevolved with their natural reservoirs and do not change appreciably in the wild. Images Fig. 2 Fig. 3 PMID:8622982

Various studies on African solidarity, survival strategies and the 'therapy man agement group' [J. M. Janzen (1978) The Quest for Therapy in Lower Zaire, Berkeley, Los Angeles & London: University of California Press] have suggested that institutionalized relationships in the form of networks or groups afford an individual access to resources, also in case of illness. My study reconsiders these arguments in ethnographic research about everyday illness management. It focuses on a heterogeneous urban neighbourhood in Abidjan and analyses who offers help to whom, and what kind of help people offer to one another. The findings show that social networks play an important but at the same time restricted role in illness management. The main source of assistance in response to affliction is household members. Apart from emotional and moral support, relatives living outside the household and non-kin play only a minor role. The social network offers help only sporadically, and very often the sick person has to ask friends and family several times before she or he receives financial or practical support. The emphasis given to social networks in the existing literature is often overestimated, at least in the case of illness. These findings implicate the importance of strengthening informal and formal security systems, especially in an urban context of economic hardship and political insecurity.

In dental health care, the application of ultrashort laser pulses enables dental tissue ablation free from thermal side effects, such as melting and cracking. However, these laser types create undesired micro- and nanoparticles, which might cause a health risk for the patient or surgeon. The aim of this study was to investigate the driving mechanisms of micro- and nanoparticle formation during ultrashort pulse laser ablation of dental tissue. Time-resolved microscopy was chosen to observe the ablation dynamics of mammoth ivory after irradiation with 660 fs laser pulses. The results suggest that nanoparticles might arise in the excited region. The thermal expansion of the excited material induces high pressure in the surrounding bulk tissue, generating a pressure wave. The rarefaction wave behind this pressure wave causes spallation, leading to ejection of microparticles.

A cross-sectional descriptive study was conducted from medical data of inpatients with tetanus in the Department of Infectious and Tropical Diseases of the University Hospital of Treichville in Abidjan from January 2003 to December 2007. In five years, 221 cases of tetanus have been hospitalized. The tetanus gateway was found in 188 patients (85%). Tetanus gateway linked to care was found in 22 patients (11.7%). Acts of care in question were intramuscular injections (10 cases) and operative procedures (12 cases). Concerning medical care by intramuscular injection, quinine (four cases), sulfadoxine-pyrimethamine (one case), and long-acting penicillin (one case) were the identified drugs. The operative procedures mainly involved were skin sutures (nine cases), cures of hernia (two cases), and flattening of Fournier's gangrene (one case). The average incubation period was 9.5 days. The invasion lasted for an average of 1.8 days. On admission, tetanus was immediately generalized for all patients with the presence of paroxysms in 20 patients (90.9%). The lethality of tetanus related care was 54.5%. The death rate in the first 48 hours of hospitalization was estimated at 83.3%. The average length of hospital stay was 14.6 days. Health workers should be involved in the prevention of tetanus in improving the quality of care and especially in reducing intramuscular injections. Also, any patient not immunized against tetanus should receive anti-tetanus serum and an update of its tetanus vaccine before any invasive procedures.

The response to HIV must be based on all situations of risk and vulnerability related to sexual behavior. Sexual practices of women who have sex with other women to HIV described in his study come within this framework. This transversal and descriptive study on the sexual practices of 150 women who have sex with other women to HIV was conducted from July to September 2010 in Abidjan. Mean age of the respondents was 26.6 years. Among them, 21.3% was illiterate, 41.4% had no earned income and 57.3% was Christians. At the time of data collection, the majority (70.7%) did not know their HIV status. The analysis of sexual practices has found 13.3% of lesbians, bisexual, 36% and 50.7% of women who say they are lesbian even if they have had sex with men. Women who have sex with other women had sexual risk behavior. It was mostly the non-systematic use of the condom during sexual relation (60%). Among the 26.7% of respondents who had lesbian practices with penetration, 40% took no precaution to prevent HIV and other sexually transmitted infections. Taking into account these results could help to develop specific strategies to promote responsible sexual practices among women who have sex with other women.

Despite the importance of beans as food, few studies are conducted to control their contamination by persistent organic pollutants (POPs), compounds of great importance because of their toxicity and tendency to accumulate in food chains. In order to evaluate the human exposure to POPs by the consumption of beans a monitoring programme was conducted on polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) residues in samples coming from Italy, Mexico, India, Japan, Ghana and Ivory Coast. All beans were extracted with an accelerated solvents extractor in triplicate; the clean-up step was done with a Florisil column; identification and quantification was carried out using a TSQ Quantum XLS Ultra GC-MS/MS in selected reaction monitoring mode. Results revealed concentrations of ∑PAHs ranged from 7.31 µg kg -1 to 686 µg kg -1 , ∑PCBs between 1.85 µg kg -1 and 43.1 µg kg -1 and ∑OCPs ranged from 1.37 µg kg -1 to 71.8 µg kg -1 . Our results showed that beans coming from Ivory Coast are the most exposed to the risk of contamination by all the pollutants investigated. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

In South-West of Burkina Faso, palm wine is produced by spontaneous fermentation of the sap from a specific palm tree Borassus akeassii and plays an important role in people's lives. Saccharomyces cerevisiae is the main agent of this alcoholic fermentation but little is known about the diversity of the isolates from palm. In this work, 39 Saccharomyces cerevisiae strains were isolated from palm wine samples collected from 14 sites in Burkina Faso, as well as 7 isolates obtained from sorghum beer (Dolo) from 3 distant sites. Their diversity was analyzed at 12 microsatellite loci, and compared to the genotypes obtained for other African yeast populations isolated from Cocoa hulks from Ghana, sorghum beer from Ivory Coast, palm wine from Djibouti Republic, and to our database of strains from miscellaneous origins (bread, beer, wine, sake, oaks…). The ploidy of these strains has been assessed as well by flow cytometry. Our results show that B. akeassii palm wine contains a specific yeast population of diploid strains, different from Dolo produced in the same area and from other palm wine strains from Ivory Coast, Nigeria, or Djibouti Republic. In contrast, Dolo strains appeared as a group of related and mainly tetraploid strains despite being isolated from different countries. Copyright © 2015 Elsevier B.V. All rights reserved.
Aperçu de precambrien de côte d'Ivoire: geologie-metallogenie

Angoran, Y.; Kadio, E.
The Ivory Coast is situated at the southern limits of the West African Craton and constitute a part of the 'Dorsale de Man'. The precambrian rocks occupy 97% of the superficial area of the country and include rocks of two orogenic episodes: the Liberian (3000-2580 Ma) and the Eburnian of lower Proterozoic (2400-1550 Ma). Liberian Orogeny, which is the most ancient, consists of gneisses, amphibo-pyroxinites, fine-grained itabirites and coarse-grained ferruginous quartzites. The aluminous gneisses, amphibo-pyroxinites and ferruginous quartzites are supracrustals that have been transformed by a high grade Catasonal metamorphism resulting in highly folded rocks. The Liberian plutons are infracrustals consisting of complex basic and ultrabasic rocks, migmatites, charnockites and granites associated with magmatites. This Liberian complex is intruded by some dolerites (2200 Ma), and kimberlites with diamond (2210-2500 Ma) which have been eroded to produce Birrimian placer deposits of Tortiya and Birrim in Ghana. The eburnian geosyncline consists of alternating subparallel intrageosynclines and intrageanticlines. The volcano-sedimentary complexes were intruded by eburnian plutons of 2100-1550 Ma. About 20 different types of mineralisations are common within the Pre-Cambrian rocks of the Ivory Coast and they are of Archaen to lower Proterozoic age. Examples of these mineral concentrations are cited in this paper.

Four-cutter molecular polymorphism of Adh and P6, and chromosome inversion polymorphism of chromosome II were investigated in 95 isogenic lines of an Ivory Coast population of Drosophila melanogaster, a species assumed to have recently spread throughout the world from a West African origin. The P6 gene showed little linkage disequilibrium with the In(2L)t inversion, although it is located within this inversion. This suggests that the inversion and the P6 locus have extensively exchanged genetic information through either double crossover or gene conversion. Allozymic variation in ADH was in linkage disequilibrium with In(2L)t and In(2R)NS inversions. Evidence suggests either that inversion linkage with the Fast allele is selectively maintained, or that this allele only recently appeared. Molecular polymorphism at the Adh locus in the Ivory Coast is not higher than in North American populations. New haplotypes specific to the African population were found, some of them connect the ``Wa(s)-like'' haplotypes found at high frequencies in the United States to the other slow haplotypes. Their relation with In(2L)t supports the hypothesis that Wa(s) recently recombined away from an In(2L)t chromosome which may be the cause of its divergence from the other haplotypes. PMID:8349110

2009-01-01
In the nights of 19 to 21 August, 2006, highly toxic waste products were dumped at various sites in Abidjan, and numerous cases of poisoning were reported to the health authorities, who were unprepared for such a problem. The research group on Environment and Health in Urban Environment from the Swiss Center of Scientific Research and its partners at the Swiss Tropical Institute undertook this study whose objectives were to: describe the epidemiologic profile of the people poisoned; identify the main clinical symptoms and the risk factors for poisoning; and recommend steps to attenuate the effects and to prevent intermediate- and long-term consequences. This cross-sectional study examined the populations living around the discharge sites (n=6). The sample size was calculated at 619 people per site, to identify a 1% risk and a standard error of 0.4%, because of variability of the human impact factor at the different sites. Households were chosen at each site by the transect technique. Six teams, each including a physician, a public health agent and a local guide collected the data, after specific training. A pilot investigation made it possible to validate the final questionnaire. Of 4573 people surveyed, 4344 people, about 95%, were home during the toxic waste discharge. In all, 2369 (51.8%) had signs of poisoning. Sex, district of residence, and presence at home at the time of the discharge were all statistically related to poisoning. The distribution of poison victims according to health centre shows that 1297 people (64.4%) visited a health center AA(3/4) 615 of them (about 47.4%) a public or official centre, and 778 (about 60%), an unofficial centre; 379 (29.2%) were managed by an NGO, 159 individuals (12.3%) by mobile units, 63 individuals (4.8%) by the unofficial public health centre, and 35 (2.7%) at an unspecified site. Of those who sought care, 673 people (about 51.8%) received a medical prescription, and 815 (or 62.7%) had been given the drug directly

We histopathologically examined gonads and chemically determined organotin compounds in tissues of the ivory shell, Babylonia japonica. Imposex (a superimposition of male-type genital organs on females) occurred in approximately 80–90% of B. japonica specimens that we examined, with the penis and vas deferens both well developed. No oviduct blockage by vas deferens formation was observed. Ovarian spermatogenesis and suppressed ovarian maturation were observed in the females that exhibited imposex, although no histopathological abnormalities were found in males. Tissue distributions of organotin compounds [tributyltin (TBT), triphenyltin (TPhT), and their metabolites] were different for butyltins and phenyltins; a remarkably high accumulation of TBT was observed in the ctenidium, osphradium, and heart, whereas high concentrations of TPhT were detected in the ovary and digestive gland. More than one-third of TBT accumulated in the digestive glands of both males and females, followed by the testis, ctenidium, muscle, and heart tissues in males and in the muscle, ovary, ctenidium, and head tissues (including the central nervous system ganglia) in females. In both males and females, more than half of total TPhT accumulated in the digestive glands, followed by the gonads. The next highest values were in the muscle, ctenidium, and heart tissues in males and in the muscle, oviduct, and head tissues in females. Both TBT and TPhT concentrations in the gonads were positively correlated with penis length in females. Our findings strongly suggest that reproductive failure in adult females accompanied by imposex, possibly induced by TBT and TPhT from antifouling paints, may have caused the marked decline of B. japonica populations in Japan.

We histopathologically examined gonads and chemically determined organotin compounds in tissues of the ivory shell, Babylonia japonica. Imposex (a superimposition of male-type genital organs on females) occurred in approximately 80-90% of B. japonica specimens that we examined, with the penis and vas deferens both well developed. No oviduct blockage by vas deferens formation was observed. Ovarian spermatogenesis and suppressed ovarian maturation were observed in the females that exhibited imposex, although no histopathological abnormalities were found in males. Tissue distributions of organotin compounds [tributyltin (TBT), triphenyltin (TPhT), and their metabolites] were different for butyltins and phenyltins; a remarkably high accumulation of TBT was observed in the ctenidium, osphradium, and heart, whereas high concentrations of TPhT were detected in the ovary and digestive gland.

[Secondary bone cancer in the Ivory Coast. Apropos of 40 cases].
Leleu, J P; Seka, R; Dechambenoit, G; Soubeyrand, J; Beda, Y B
1983-01-01
From the statistics dealing with cancer yielded in the Internal Medicine Department, Treichville Hospital, secundary bone cancer appears with a low percentage. The short expectation of life and the reluctance of African patients to report to the hospital must be considered to appreciate these data. Most often, at their admittance, cases show numerous and large metastasises. Bone tumors related to a primitive liver cancer are rare. More often, metastasises in prostate cancer may be observed. They are generally osteocondensing. Breast cancer is, for its frequency, ranking just after it. In one third of the cases, the origine has not been cleared out.

Congenital abnormalities constitute one of the major causes of infant mortality, particularly in developing countries. The aim of this study was to describe the epidemiology of congenital anomalies in Cote d'Ivoire. It was a multicentric study of three academic hospitals and the Heart Institute of Abidjan over 10 years. The epidemiologic Data concerned the Parturients, the annual frequency of congenital abnormalities. Distribution of the congenital abnormalities according to the organs, overall mortality and lethality of congenital abnormalities were evaluated. Over 10 years, 1.632 newborns with 1.725 congenital anomalies were recorded. Frequency was 172.5 congenital anomalies per annum. Parturients were less than 35 years in 33% of cases, multigravida in 20%, multiparous in 18% and had a low socio economic status in 96% of cases. Prenatal diagnosis of congenital anomalies was performed in 1.5%. Congenital anomalies were orthopedic in 34%, neurological in 17%, gastrointestinal in 15%, facial in 11.5%, parietal in 13%, urogenital in 9% and cardiac in 0.5% of cases. The overall mortality rate of congenital anomalies was 52% and gastroschisis was the most lethal disease with 100% mortality. This descriptive study reveals the low socio economic status of Parturients with congenital anomalies and their poor prenatal diagnosis. These factors explain the very high mortality of congenital anomalies due to a delay management in our country in which medical expenses were borne by parents and where technical platforms remain obsoletes for good resuscitation and neonatal surgery.

Whereas the coronary artery disease death rate has declined in high-income countries, the incidence of acute coronary syndromes (ACS) is increasing in sub-Saharan Africa, where their management remains a challenge. To propose a consensus statement to optimize management of ACS in sub-Saharan Africa on the basis of realistic considerations. The AFRICARDIO-2 conference (Yamoussoukro, May 2015) reviewed the ongoing features of ACS in 10 sub-Saharan countries (Benin, Burkina-Faso, Congo-Brazzaville, Guinea, Ivory Coast, Mali, Mauritania, Niger, Senegal, Togo), and analysed whether improvements in strategies and policies may be expected using readily available healthcare facilities. The outcome of patients with ACS is affected by clearly identified factors, including: delay to reaching first medical contact, achieving effective hospital transportation, increased time from symptom onset to reperfusion therapy, limited primary emergency facilities (especially in rural areas) and emergency medical service (EMS) prehospital management, and hence limited numbers of patients eligible for myocardial reperfusion (thrombolytic therapy and/or percutaneous coronary intervention [PCI]). With only five catheterization laboratories in the 10 participating countries, PCI rates are very low. However, in recent years, catheterization laboratories have been built in referral cardiology departments in large African towns (Abidjan and Dakar). Improvements in patient care and outcomes should target limited but selected objectives: increasing awareness and recognition of ACS symptoms; education of rural-based healthcare professionals; and developing and managing a network between first-line healthcare facilities in rural areas or small cities, emergency rooms in larger towns, the EMS, hospital-based cardiology departments and catheterization laboratories. Faced with the increasing prevalence of ACS in sub-Saharan Africa, healthcare policies should be developed to overcome the multiple

Low molecular weight flavan-3-ols are thought to be responsible, in part, for the cardiovascular benefits associated with cocoa powder and dark chocolate. The levels of epicatechin and catechin were determined in raw and conventionally fermented cacao beans and during conventional processing, which included drying, roasting, and Dutch (alkali) processing. Unripe cacao beans had 29% higher levels of epicatechin and the same level of catechin compared to fully ripe beans. Drying had minimal effect on the epicatechin and catechin levels. Substantial decreases (>80%) in catechin and epicatechin levels were observed in fermented versus unfermented beans. When both Ivory Coast and Papua New Guinea beans were subjected to roasting under controlled conditions, there was a distinct loss of epicatechin when bean temperatures exceeded 70 °C. When cacao beans were roasted to 120 °C, the catechin level in beans increased by 696% in unfermented beans, by 650% in Ivory Coast beans, and by 640% in Papua New Guinea fermented beans compared to the same unroasted beans. These results suggest that roasting in excess of 70 °C generates significant amounts of (-)-catechin, probably due to epimerization of (-)-epicatechin. Compared to natural cocoa powders, Dutch processing caused a loss in both epicatechin (up to 98%) and catechin (up to 80%). The epicatechin/catechin ratio is proposed as a useful and sensitive indicator for the processing history of cacao beans.

Drought settled over West Africa's Ivory Coast region when wet season rains came late in 2007. Instead of beginning in February, the rainy season didn't start until March, and steady rains didn't start until late March, said the Famine Early Warning System Network. Though the rain had started to alleviate the drought, vegetation was still depressed in parts of Cote d'Ivoire (Ivory Coast) between March 22 and April 6, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured the data used to make this image. The image shows current vegetation conditions compared to average conditions recorded since 2000. Areas where plants are growing more slowly or more sparsely than average are brown, while areas where vegetation is denser than average are green. The brown tint that dominates the image indicates that plants through most of the country are more sparse than normal. Among the crops affected by the lack of rain was West Africa's cocoa crop. About 70 percent of the world's cocoa comes from West Africa, and Cote d'Ivoire is a top grower, said Reuters. Cocoa prices climbed as the crop fell short. Farmers called the drought the worst in living memory, Reuters said. The delay in rainfall also led to water shortages in parts of Cote d'Ivoire, according to the United Nations Office for the Coordination of Humanitarian Affairs.

Macroeconomic policy requirements may limit the capacity of national and international policy-makers to allocate sufficient resources for scaling-up access to HIV care and treatment in developing countries. An endogenous growth model, which takes into account the evolution of society's human capital, was used to assess the macroeconomic impact of policies aimed at scaling-up access to HIV/AIDS treatment in six African countries (Angola, Benin, Cameroon, Central African Republic, Ivory Coast and Zimbabwe). The model results showed that scaling-up access to treatment in the affected population would limit gross domestic product losses due to AIDS although differently from country to country. In our simulated scenarios of access to antiretroviral therapy, only 10.3% of the AIDS shock is counterbalanced in Zimbabwe, against 85.2% in Angola and even 100.0% in Benin (a total recovery). For four out of the six countries (Angola, Benin, Cameroon, Ivory Coast), the macro-economic gains of scaling-up would become potentially superior to its associated costs in 2010. Despite the variability of HIV prevalence rates between countries, macro-economic estimates strongly suggest that a massive investment in scaling-up access to HIV treatment may efficiently counteract the detrimental long-term impact of the HIV pandemic on economic growth, to the extent that the AIDS shock has not already driven the economy beyond an irreversible 'no-development epidemiological trap'.

Simian immunodeficiency viruses (SIVs) are found in an extensive number of African primates and humans continue to be exposed to these viruses by hunting and handling of primate bushmeat. Full-length genome sequences were obtained from SIVs derived from two Colobinae species inhabiting the Taï forest, Ivory Coast, each belonging to a different genus: SIVwrc from western red colobus (Piliocolobus badius badius) (SIVwrcPbb-98CI04 and SIVwrcPbb-97CI14) and SIVolc (SIVolc-97CI12) from olive colobus (Procolobus verus). Phylogenetic analysis showed that western red colobus are the natural hosts of SIVwrc, and SIVolc is also a distinct species-specific lineage, although distantly related to the SIVwrc lineage across the entire length of its genome. Overall, both SIVwrc and SIVolc, are also distantly related to the SIVlho/sun lineage across the whole genome. Similar to the group of SIVs (SIVsyk, SIVdeb, SIVden, SIVgsn, SIVmus, and SIVmon) infecting members of the Cercopithecus genus, SIVs derived from western red and olive colobus, L'Hoest and suntailed monkeys, and SIVmnd-1 from mandrills form a second group of viruses that cluster consistently together in phylogenetic trees. Interestingly, the divergent SIVcol lineage, from mantled guerezas (Colobus guereza) in Cameroon, is also closely related to SIVwrc, SIVolc, and the SIVlho/sun lineage in the 5′ part of Pol. Overall, these results suggest an ancestral link between these different lentiviruses and highlight once more the complexity of the natural history and evolution of primate lentiviruses.

Animal-source foods are important causes of food-borne illness, and milk and dairy products can contain pathogenic microorganisms. We conducted a stochastic assessment of the risk of ingesting milk contaminated with specific microbial pathogens (Escherichia coli, Staphylococcus aureus, and Enterococcus spp.) in Abidjan, Côte d'Ivoire. We carried out structured interviews and focus group discussions with farmers (n = 15), vendors (n = 17), and consumers (n = 188) to characterize dairy production systems and milk consumption behavior. Microbiological sampling was conducted at different points between milking and sale. A risk model was developed, and the risk of consuming contaminated raw milk was estimated by Monte Carlo simulation. The investigation into local raw milk consumption patterns showed that the proportion of raw milk consumption was 51.6% in people who consume milk. The probability of ingestion of marketed raw milk that failed to meet standards for this group of bacteria was 29.9% and about 652 consumers per day were estimated to ingest contaminated milk. Microbiological tests from the farm showed that 7.2% of samples taken from milkers' hands, 4.4% of water samples (water used to rinse milk containers or milking utensils (calabash, plastic bottle, filters, buckets), 4.4% of environmental samples (air pollution), 13.2% of samples from milking utensils, and 4.9% of samples from cows' udders were contaminated with one or more of these pathogens. About 624.6 L of marketed raw milk would need to be discarded per day if discarding milk was chosen as the option of risk reduction. The destruction of this milk would result in a potential loss of Euro623.9 per day for all producers. The risk of human illness from consumption of raw milk could be mitigated by raising awareness about heat treatment of milk and good hygiene practices in the dairy chain.

Two science-arts approaches are emerging as effective means to convey "futurethinking" to learners: systems gaming and experiential futures. FutureCoast exemplifies the latter: by engaging participants with voicemails supposedly leaking from the cloud of possible futures, the storymaking game frames the complexities of climate science in relatable contexts. Because participants make the voicemails themselves, FutureCoast opens up creative ways for people to think about possibly climate-changed futures and personal ways to talk about them. FutureCoast is a project of the PoLAR Partnership with a target audience of informal adult learners primarily reached via mobile devices and online platforms. Scientists increasingly use scenarios and storylines as ways to explore the implications of environmental change and societal choices. Stories help people make connections across experiences and disciplines and link large-scale events to personal consequences. By making the future seem real today, FutureCoast's framework helps people visualize and plan for future climate changes. The voicemails contributed to FutureCoast are spread through the game's intended timeframe (2020 through 2065). Based on initial content analysis of voicemail text, common themes include ecosystems and landscapes, weather, technology, societal issues, governance and policy. Other issues somewhat less frequently discussed include security, food, industry and business, health, energy, infrastructure, water, economy, and migration. Further voicemail analysis is examining: temporal dimensions (salient time frames, short vs. long term issues, intergenerational, etc.), content (adaptation vs. mitigation, challenges vs. opportunities, etc.), and emotion (hopeful, resigned, etc. and overall emotional context). FutureCoast also engaged audiences through facilitated in-person experiences, geocaching events, and social media (Tumblr, Twitter, Facebook, YouTube). Analysis of the project suggests story

Background Chloroquine (CQ) was the main malaria therapy worldwide from the 1940s until the 1990s. Following the emergence of CQ-resistant Plasmodium falciparum, most African countries discontinued the use of CQ, and now promote artemisinin-based combination therapy as the first-line treatment. This change was generally initiated during the last decade in West and Central Africa. The aim of this study is to describe the changes in CQ susceptibility in this African region, using travellers returning from this region as a sentinel system. Methods The study was conducted by the Malaria National Reference Centre, France. The database collated the pfcrtK76T molecular marker for CQ susceptibility and the in vitro response to CQ of parasites from travellers’ isolates returning from Senegal, Mali, Ivory Coast or Cameroon. As a proxy of drug pressure, data regarding CQ intake in febrile children were collated for the study period. Logistic regression models were used to detect trends in the proportions of CQ resistant isolates. Results A total of 2874 parasite isolates were genotyped between 2000–2011. The prevalence of the pfcrt76T mutant genotype significantly decreased for Senegal (from 78% to 47%), Ivory Coast (from 63% to 37%), Cameroon (from 90% to 59%) and remained stable for Mali. The geometric mean of the 50% inhibitory concentration (IC50) of CQ in vitro susceptibility and the proportion of resistant isolates (defining resistance as an IC50 value > 100 nM) significantly decreased for Senegal (from 86 nM (59%) to 39 nM (25%)), Mali (from 84 nM (50%) to 51 nM (31%)), Ivory Coast (from 75 nM (59%) to 29 nM (16%)) and Cameroon (from 181 nM (75%) to 51 nM (37%)). Both analyses (molecular and in vitro susceptibility) were performed for the 2004–2011 period, after the four countries had officially discontinued CQ and showed an accelerated decline of the resistant isolates for the four countries. Meanwhile, CQ use among children significantly deceased in this

Two field studies to assess the health implications for farmers applying two different formulations containing organophosphorus (OP) pesticides to cotton by hand-held ULV are described. The first study, carried out in the Ivory Coast, involved the application of an endrin/DDT/methylparathion (MEP) formulation in an aromatic hydrocarbon solvent. The second study took place in Indonesia with a 20% monocrotophos formulation in a mixture of a glycol and a glycol ether. Both studies were carried out under actual field conditions. The purpose of the studies was to get a good assessment of the health hazards of the particular formulation, used under the specific circumstances and agronomic requirements of the area of application and taking into account all local, climatic and cultural conditions that could be of possible influence. The results showed that in both studies skin exposures took place during application and especially during handling, filling and cleaning, and that inhalation of spray mist was negligible. Absorption was confirmed by the presence in urine of metabolites of endrin and methylparathion in the Ivory Coast study, and of dimethyl phosphate in the Indonesia study. No clinical signs or symptoms of intoxication were discovered in either study, nor were inhibitions of cholinesterase (ChE) activity of health significance established under the conditions of the studies. In addition, various practical aspects such as choice of apparatus, of formulation, the application procedures etc. are discussed.

This MODIS true-color image, acquired March 4, 2002, shows a phytoplankton bloom along the coast of Namibia. Phytoplankton is a microscopic organism that utilizes chlorophyll, which sunlight reflects off of to create this intense blue-green color in the water. Also prominent in this image is the Skeleton Coast Game Park, which runs along Namibia's northern coast and here glows a beautiful coral-orange color.

Background Retracing the genetic histories of the descendant populations of the Slave Trade (16th-19th centuries) is particularly challenging due to the diversity of African ethnic groups involved and the different hybridisation processes with Europeans and Amerindians, which have blurred their original genetic inheritances. The Noir Marron in French Guiana are the direct descendants of maroons who escaped from Dutch plantations in the current day Surinam. They represent an original ethnic group with a highly blended culture. Uniparental markers (mtDNA and NRY) coupled with HTLV-1 sequences (env and LTR) were studied to establish the genetic relationships linking them to African American and African populations. Results All genetic systems presented a high conservation of the African gene pool (African ancestry: mtDNA = 99.3%; NRY = 97.6%; HTLV-1 env = 20/23; HTLV-1 LTR = 6/8). Neither founder effect nor genetic drift was detected and the genetic diversity is within a range commonly observed in Africa. Higher genetic similarities were observed with the populations inhabiting the Bight of Benin (from Ivory Coast to Benin). Other ancestries were identified but they presented an interesting sex-bias. Whilst male origins spread throughout the north of the bight (from Benin to Senegal), female origins were spread throughout the south (from the Ivory Coast to Angola). Conclusions The Noir Marron are unique in having conserved their African genetic ancestry, despite major cultural exchanges with Amerindians and Europeans through inhabiting the same region for four centuries. Their maroon identity and the important number of slaves deported in this region have maintained the original African diversity. All these characteristics permit to identify a major origin located in the former region of the Gold Coast and the Bight of Benin; regions highly impacted by slavery, from which goes a sex-biased longitudinal gradient of ancestry.

Chapter 9: The rock coast of the USA
Hapke, Cheryl J.; Adams, Peter N.; Allan, Jonathan; Ashton, Andrew; Griggs, Gary B.; Hampton, Monty A.; Kelly, Joseph; Young, Adam P.
2014-01-01
The coastline of the USA is vast and comprises a variety of landform types including barrier islands, mainland beaches, soft bluffed coastlines and hard rocky coasts. The majority of the bluffed and rocky coasts are found in the northeastern part of the country (New England) and along the Pacific coast. Rocky and bluffed landform types are commonly interspersed along the coastline and occur as a result of relative lowering of sea level from tectonic or isostatic forcing, which can occur on timescales ranging from instantaneous to millenia. Recent research on sea cliffs in the contiguous USA has focused on a broad range of topics from documenting erosion rates to identifying processes and controls on morphology to prediction modelling. This chapter provides a detailed synthesis of recent and seminal research on rocky coast geomorphology along open-ocean coasts of the continental United States (USA).

Statistics of rocky coast erosion and percolation theory
NASA Astrophysics Data System (ADS)
Baldassarri, A.; Sapoval, B.
2012-04-01
The dynamics of rocky coasts is an erratic phenomenon featuring numerous small erosion events, but sometimes large dramatic collapses. In this sense, its study should not limit or rely on average erosion rates. Recent studies, based on historical as well as recent data, have indicated that the frequency of magnitude of erosion events display long tail distribution, similar to what observed in landslide. In other words the time evolution of a coast morphology does not enter the classical category of Gaussian process, but rather that of critical systems in physics. We recently proposed a minimal dynamical model of rocky coast erosion which is able to reproduce the diversity of rocky coast morphologies and their dynamics. This model is based on a single, simple ingredient, the retroaction of the coast morphology on the erosive power of the sea. It follows from the idea that erosion can spontaneously create irregular seashores, but, in turn, the geometrical irregularity of the coast participates to the damping of sea-waves, decreasing the average wave amplitude and erosive power. The resulting mutual self-stabilization dynamics of the sea erosion power and coastal irregular morphology leads spontaneously the system to a critical dynamics. Our results indicate then that rocky coast erosion and the statistical theory of percolation are closely related. In this framework, the sometimes fractal geometry of coastlines can be recovered and understood in terms of fractal dimension of the external perimeter of a percolation cluster. From a more practical point of view, the analogy with percolation interfaces means that the coast constitutes a strong, but possibly fragile, barrier to sea erosion, emerging from a self-organised selection process. Accordingly, the effect of a slow weathering degradation of the rocks mechanical properties, as well as other perturbations from natural or human cause, can trigger random and large erosion events difficult to predict and control.

Background Mitochondrial toxicity was described in infants exposed to long-term antiretroviral regimens (ARVs) containing nucleoside analogues for the prevention of mother-to-child transmission of HIV (PMTCT). We measured the serum lactate levels in children born to HIV-1 infected (HIV+) African women receiving short-term ARV PMTCT regimens. Methods A prospective study was conducted in women-child pairs from the third trimester of pregnancy to three months of life. The exposed group was formed by children exposed in utero to nucleoside analogue ARVs, zidovudine (ZDV) or ZDV + lamivudine (3TC) from 32–36 weeks of amenorrhea until delivery. All these women received nevirapine single-dose (NVPsd) at the beginning of labor. The children received ZDV during the first 7 days of life and a NVPsd at day 3. The control group was formed by infants born to HIV+ women who had received NVPsd only and not exposed to nucleoside analogue ARVs. Serum lactate levels were measured at 4, 6 and 12 weeks of life by Cobas Integra 400™. Results A total of 836 blood samples from 338 infants were collected (262 exposed and 76 controls). Median lactacidemia was 1.8 mmol/l, Interquartile Range [1.2–2.7 mmol/l]). Overall serum lactate levels ≥2.5 mmol/l, defining hyperlactatemia were observed in 39 of the 292 infants who had at least two serum lactate measurements, 13.4%, 95% confidence Interval [9.6–17.8%]. The three-month period prevalence of hyperlactatemia did not differ between the exposed group (13.1%) and the control group (14.3%) (p=0.84). All serum lactate levels returned to normal values in all subsequent samples No case of symptomatic hyperlactatemia was detected during the study period. Conclusion Increased lactate levels were identified equally in infants whose mother received a short-term of nucleoside analogues or NVPsd for PMTCT. Although not rare, hyperlactatemia was not related to short-term exposure to nucleoside analogue ARVs PMID:16950945

Tsunami Risk for the Caribbean Coast

2004-12-01
The tsunami problem for the coast of the Caribbean basin is discussed. Briefly the historical data of tsunami in the Caribbean Sea are presented. Numerical simulation of potential tsunamis in the Caribbean Sea is performed in the framework of the nonlinear-shallow theory. The tsunami wave height distribution along the Caribbean Coast is computed. These results are used to estimate the far-field tsunami potential of various coastal locations in the Caribbean Sea. In fact, five zones with tsunami low risk are selected basing on prognostic computations, they are: the bay "Golfo de Batabano" and the coast of province "Ciego de Avila" in Cuba, the Nicaraguan Coast (between Bluefields and Puerto Cabezas), the border between Mexico and Belize, the bay "Golfo de Venezuela" in Venezuela. The analysis of historical data confirms that there was no tsunami in the selected zones. Also, the wave attenuation in the Caribbean Sea is investigated; in fact, wave amplitude decreases in an order if the tsunami source is located on the distance up to 1000 km from the coastal location. Both factors wave attenuation and wave height distribution should be taken into account in the planned warning system for the Caribbean Sea.

The total dietary fiber, sugar, protein, lipid profile, sodium, and energy contents of 11 raw cashew kernel (Anacardium occidentale L.) samples from India, Brazil, Ivory Coast, Kenya, Mozambique, and Vietnam were determined. Total fat was the major component accounting for 48.3% of the total weight, of which 79.7% were unsaturated FA (fatty acids), 20.1% saturated FA, and 0.2% trans FA. Proteins, with 21.3 g/100 g, were ranked second followed by carbohydrates (20.5 g/100 g). The average sodium content was 144 mg/kg. Fourteen FA were identified among which oleic acid was the most abundant with a contribution of 60.7% to the total fat, followed by linoleic (17.77%), palmitic (10.2%), and stearic (8.93%) acids. The mean energy content was 2525 kJ/100g. Furthermore, the sterol profile and content, amino acids, vitamins, and minerals of four raw cashew kernel samples from Brazil, India, Ivory Coast, and Vietnam were determined. β-Sitosterol with 2380 ± 4 mg/kg fat was the most occurring sterol. Glutamic acid, with 4.60 g/100 g, was the amino acid with highest presence, whereas tryptophan with 0.32 g/100 g was the one with lower presence. Vitamin E with an average contribution of 5.80 mg/100 g was the most abundant vitamin. Potassium with a mean value of 6225 mg/kg was the mineral with highest amount in cashew samples.
Exploring universal patterns in human home-work commuting from mobile phone data.
Kung, Kevin S; Greco, Kael; Sobolevsky, Stanislav; Ratti, Carlo
2014-01-01
Home-work commuting has always attracted significant research attention because of its impact on human mobility. One of the key assumptions in this domain of study is the universal uniformity of commute times. However, a true comparison of commute patterns has often been hindered by the intrinsic differences in data collection methods, which make observation from different countries potentially biased and unreliable. In the present work, we approach this problem through the use of mobile phone call detail records (CDRs), which offers a consistent method for investigating mobility patterns in wholly different parts of the world. We apply our analysis to a broad range of datasets, at both the country (Portugal, Ivory Coast, and Saudi Arabia), and city (Boston) scale. Additionally, we compare these results with those obtained from vehicle GPS traces in Milan. While different regions have some unique commute time characteristics, we show that the home-work time distributions and average values within a single region are indeed largely independent of commute distance or country (Portugal, Ivory Coast, and Boston)-despite substantial spatial and infrastructural differences. Furthermore, our comparative analysis demonstrates that such distance-independence holds true only if we consider multimodal commute behaviors-as consistent with previous studies. In car-only (Milan GPS traces) and car-heavy (Saudi Arabia) commute datasets, we see that commute time is indeed influenced by commute distance. Finally, we put forth a testable hypothesis and suggest ways for future work to make more accurate and generalizable statements about human commute behaviors.
Retro-action model for the erosion of rocky coasts
NASA Astrophysics Data System (ADS)
Sapoval, B.; Baldassarri, A.
2009-12-01
Rocky coasts are estimated to represent 75% of the world’s shorelines [1]. We discuss various situations where the formation of rocky coast morphology could be attributed to the retro-action of the coast morphology on the erosive power of the see. In the case of rocky coasts, erosion can spontaneously create irregular seashores. But, in turn, the geometrical irregularity participates to the damping of sea-waves, decreasing the average wave amplitude and erosive power. There may then exist a mutual self-stabilization of the waves amplitude together with the irregular morphology of the coast. A simple model of such stabilization is discussed. It leads, through a complex dynamics of the earth-sea interface, to the spontaneous appearance of an irregular sea-shore. The final coast morphology is found to depend on the morphology/damping coupling of the coast and on the possible existence of built-in correlations within the coast lithologic properties. This is illustrated in the figure. In the limit case where the morphology/damping coupling is weak and when the earth lithology distribution exhibit only short range correlations, the process spontaneously build fractal morphologies with a dimension close to 4/3 [2]. It is shown that this dimension refers to the dimension of the so-called accessible perimeter in gradient percolation. However, even rugged but non-fractal sea-coasts morphology may emerge for strong damping or during the erosion process. When the distributions of the lithologies exhibit long range correlations, a variety of complex morphologies are obtained which mimics observed coastline complexity, well beyond simple fractality. On a somewhat different perspective, the design of breakwaters is suggested to be improved by using global irregular geometry with features sizes of the order of the wave-length of the sea oscillations.

Satellite chlorophyll off the British Columbia Coast, 1997-2010

We examine the spatial and temporal variability of satellite-sensed sea surface chlorophyll off the west coast of North America from 1997 to 2010, with focus on coastal British Columbia. The variability in surface chlorophyll is complex. Whereas the spring bloom generates the highest phytoplankton concentration for coastal Alaska, the north and east coasts of Haida Gwaii, Queen Charlotte Sound, the Strait of Georgia, and coastal Oregon and California, it is the fall bloom that normally generates the highest concentration for the west coast of Vancouver Island, Juan de Fuca Strait, and the west coast of Washington. The highest satellite-sensed chlorophyll concentrations occur in the Strait of Georgia, where mean values are at least 2 times higher than elsewhere in the northeast Pacific. Moreover, the annual average surface chlorophyll concentration increased significantly in the Strait of Georgia during this period, with highest concentration observed during the near neutral ENSO conditions of the spring of 2007. The next highest concentrations occur off southwest Vancouver Island but have no statistically significant trend. The lowest average peak chlorophyll concentration is observed off Southern California. The timing of the highest chlorophyll concentration is latest off the coast of Washington and earliest off the coast of Southern California. Small increasing concentration trends are observed off the Washington and California coasts.

A robust update on the latest ocean governance developments in the West Coast region of the U.S. will be provided, highlighting implementation of the National Ocean Policy and ongoing dialog among federal, state and tribal entities and coastal stakeholders at a range of scales. The link between ecosystem-based management (EBM) as a guiding principle and meaningful management outcomes will discussed, guided by the latest ocean policy priorities from local, state, tribal and regional scales in the West Coast. The West Coast Regional Planning Body has been recently initiated under the framework provided by the National Ocean Policy, bringing together a formal partnership of state and tribal governments with federal agencies in a way never before achieved in the region. The newly reformed West Coast Ocean Partnership builds upon efforts of the West Coast Governors Alliance on Ocean Health to continue to address priority ocean policy topics, while other regional efforts are identifying data, science and tools to support an EBM approach. All of these will be discussed in detail, providing both up-to-date reports on the latest West Coast activities, while illustrating lessons learned from past regional efforts and exactly how EBM has been effectively integrated. The West Coast of the U.S. is a unique region in terms of geographic scale, governance structure and history of innovative ocean management approaches. Using opportunities provided by recent state, tribal, regional and national policy initiatives, the West Coast has undertaken a range of activities to better coordinate ocean management while enhancing dialogs to support it. This presentation will provide a concise summary of current efforts, demonstrating how policy is being translated into significant action and highlighting opportunities to build on successful outcomes to date.

In order to better understand the regional trends of change along the California coast, the U.S. Geological Survey is quantifying both sandy shoreline change and coastal cliff retreat for the state. The resulting database was used to examine the dynamics of the beach/cliff system. We found inconsistent evidence of a relationship between rates of cliff retreat and shoreline change on the spatial scale of 100-km cells. However, when the data are correlated within individual regions, a strong relationship exists between the geomorphology of the coast and the behavior of the beach/cliff system. Areas of high-relief coast show negative correlations, indicating that higher rates of cliff retreat correlate with lower rates of shoreline erosion. In contrast, low- to moderate-relief coasts show strong positive correlations.

Geographic signatures of North American West Coast estuaries

West Coast estuaries are geologically young and composed of a variety of geomorphological types. These estuaries range from large fjords to shallow lagoons; from large to low freshwater flows. Natural hazards include E1 Niños, strong Pacific storms, and active tectonic activity. West Coast estuaries support a wide range of living resources: five salmon species, harvestable shellfish, waterfowl and marine birds, marine mammals, and a variety of algae and plants. Although populations of many of these living resources have declined (salmonids), others have increased (marine mammals). West Coast estuaries are also centers of commerce and increasingly large shipping traffic. The West Coast human population is rising faster than most other areas of the U.S. and Canada, and is distributed heavily in southern California, the San Francisco Bay area, around Puget Sound, and the Fraser River estuary. While water pollution is a problem in many of the urbanized estuaries, most estuaries do not suffer from poor water quality. Primary estuarine problems include habitat alterations, degradation, and loss; diverted freshwater flows; marine sediment contamination; and exotic species introductions. The growing West Coast economy and population are in part related to the quality of life, which is dependent on the use and enjoyment of abundant coastal natural resources.

Coastal areas are staggering under an onslaught of human activity. We are presently in the process of destroying 70 percent of the world`s 600,000 square kilometers of coral reefs, an ecosystem containing some 200,000 different species and rivaling tropical rain forests in biodiversity. A combination of pollution, habitat destruction, and gross overfishing has led to the collapse of major fisheries and paved the way for malnutrition and disease in regions where people fish for subsistence. Globally, little is being done to manage the crisis of our coasts. Management strategies, if they exist at all, often deal with economic development alongmore » a wafer-thin strip of coastal land. Resource degradation is ignored, and watershed management is mostly rhetoric. Although some 55 countries have drawn up coastal management plans, only a handful have been properly implemented. Coasts must be managed in an integrated manner that takes into account the full range of human activities. Initiating this process is costly, time-consuming, and difficult. Yet we have more than three decades of accumulated experience to draw on.« less

In August 2006, toxic wastes were discharged in the district of Abidjan, causing important health consequences in many households in the area. In order to appreciate the socio-economic impact of the consequences of toxic waste discharge on the households and of the measures taken by the authorities to deal with this catastrophe, and to appreciate the spatial extent of the pollution, we undertook a multidisciplinary transversal investigation at the sites of discharge of oxic waste, from October the 19th to December the 8th, 2006, using a transect sampling methodology. This paper presents the results related to the socio-economic aspects of the survey while the environmental and epidemiological results are presented in two other published papers. The socioeconomics investigation, conducted using a questionnaire, concerned 809 households across the various sites of discharge of toxic waste. More than 62% of households had at least one person who had been affected by toxic waste (affected households). 62.47% of these households were in Cocody district (with 2 sites and 4 points of discharge), 30.14% in Abobo district (with 2 sites and 3 points) and 7.39% in Koumassi district (with 1 site and 1 point). To escape the bad smell and the nuisance, 22.75% of the 501 "affected" households had left their houses. To face the health consequences generated by the toxic waste, 30.54% of the "affected" households engaged expenses. Those were on average of 92 450 FCFA (€141), with a minimum of 1 000 FCFA (€1.5) and a maximum of 1500000 FCFA (€2.287), in spite of the advertisement of the exemption from payment treatment fees made by the government. The decision of destroying cultures and farms near the points of discharge of the toxic products in a radius of 200 meters, taken by the authorities, touched 2.22% of the households. For these households, it did nothing but worsen their state of poverty, since the zone of influence of the toxic waste went well beyond the 200 meters

Many arctic coastal systems are experiencing altered thermal and hydrological regimes. Of particular note within the High Arctic is Svalbard, a region undergoing a distinct and sustained rise in mean annual temperatures. Hornsund, at the southern tip of the Svalbard archipelago, is situated at the northern extreme of the North Atlantic current and as such provides a site of unique climate sensitivity with a concentration of geomorphic processes. There is a paucity of studies achieving sufficient resolution to account for geomorphic behaviour and over timescales that allow climatic conditioning to be considered. This research utilises high resolution multiscale surface monitoring and characterisation to quantify and model both contemporary and relic cliff responses in order to revisit one of the first quantitative studies, undertaken almost sixty years ago, on the rates and intensities of rock coast change. The fragmentation and failure in contemporary coastal cliff responses reflects a decrease in the overall rates of change relative to historic rates during a period that has seen the loss of an icefoot that regularly lasted until late summer and a transition to open water coastal dynamics. To investigate the drivers of rock degradation and failure, thermal analyses that characterise both spatial and temporal patterns across and within the rock coast have been used to indicate a potential shift in process activity zones. The significance of localised influences such as storm influences, iceberg influxes and topographic shading highlights some considerations for the development of broader scale models of rock coast evolution.

Exploration in central and southern Africa continued to expand during 1980. The greatest concentration of activity was in Nigeria. However, there was considerable increase in the level of exploratory work in Cameroon and Congo. Significant new finds have been made in Ivory Coast. Geological and geophysical activity was carried out in 18 of the countries, with those in the western part having the largest share. Seismic work involved 225 party months of operation. Most of this time was spent on land, but marine operations accounted for 73,389 km of new control. Gravity and magnetic data were recorded during the marinemore » surveys, and several large aeromagnetic projects were undertaken to obtain a total of 164,498 line km of data. Exploratory and development drilling accounted for a total of 304 wells and 2,605,044 ft (794,212 m) of hole. The 92 exploratory wells that were drilled resulted in 47 oil and gas discoveries. In development drilling 89% of the 212 wells were successful. At the end of the year, 27 exploratory wells were underway, and 34 development wells were being drilled for a total of 61. Oil production from the countries that this review covers was 918,747,009 bbl in 1980, a drop of about 9% from the previous year. Countries showing a decline in production were Nigeria, Gabon, Cabinda, and Zaire. Increases were recorded in Cameroon, Congo, and Ghana. A new country was added to the list of producers when production from the Belier field in Ivory Coast came on stream. 33 figures, 15 tables.« less

UNAIDS has launched an 'HIV Drug Access Initiative' in the Ivory Coast, Uganda, Chile, and Vietnam; the pilot project will attempt to improve access to HIV drugs. Public and private sector efforts will be coordinated. The Glaxo Wellcome, Hoffman-La Roche, and Virco pharmaceutical companies will participate. Each country will 1) adapt its present system with regard to HIV and 2) establish both an HIV drug advisory board and a non-profit company which will import the drugs. Health ministries within each country will be required to find sources of funding for the programs. Uganda will probably use funds from its sexually transmitted disease (STD) program, which is supported by the World Bank; the Ivory Coast will combine corporate contributions, new tariffs, and non-profit insurance system monies into a 'solidarity fund.' UNAIDS funds will be used for oversight and evaluation. UNAIDS also released a review of 68 studies which examined the impact of sex education on the sex behavior of young people; it indicated that, in 65 of the studies, sex education did not increase the sexual activity of youth. UNAIDS concluded that quality programs helped delay first intercourse and often reduced the number of sexual partners, resulting in reduced rates of STDs and unplanned pregnancy. UNAIDS further concluded that effective sex education should begin before the onset of sexual activity, and curriculums should be focused. Openness in communicating about sex should be encouraged, and social and media influences on behavior should be addressed. Young people should be taught negotiating skills (how to say 'no' to sex and how to insist on safer sex).

Sub-Saharan Africa (SSA) has been undergoing a devastating economic recession forcing the need for structural adjustment programs (SAP's) to correct many of the economic imbalances, but the effects of SAP's have been to destroy rather than to adjust, making the situation worse than ever. Budgets for social welfare expenditures have been depleted and entire families cannot plan a day ahead. The last thing SSA needed was AIDS to add to the region's poverty and misery. The transmission of AIDS has been facilitated by 2 movements: 1) urbanization and 2) spatial migration from the rural areas to the urban. Some other routes that facilitate the transmission of AIDS in SSA are: 1) returning migrants or people with long-term jobs from countries such as Burkina Faso returning to the Ivory Coast; 2) the truck drivers on the highways; 3) prostitution such as in the Ivory Coast with the rich coffee or cocoa planters; 4) multiple sex partners; 5) wars of liberation such as in Angola; and 6) vertical transmission between mother and child. The SAP's have further increased the transmission of AIDS because of the poverty of the region. For example, some of the immediate effects of SAP's have been intensification of migration for economic reasons, destruction of the traditional family and the growth of urban prostitution. Demographic effects of AIDS has been the increase in mortality. It is important that future surveys on AIDS in SSA should be the responsibility of African researchers to ensure that they do not also become "prophets of apocalypse" as have many researchers from the West. These African led surveys and outcomes should become the basis of an AIDS IEC program.
A numerical retroaction model relates rocky coast erosion to percolation theory
NASA Astrophysics Data System (ADS)
Sapoval, B.; Baldassarri, A.
2011-12-01
Rocky coasts are estimated to represent 75% of the world's shorelines [1]. We discuss various situations where the formation of rocky coast morphology could be attributed to the retroaction of the coast morphology on the erosive power of the see. In the case of rocky coasts, erosion can spontaneously create irregular seashores. But, in turn, the geometrical irregularity participates to the damping of sea-waves, decreasing the average wave amplitude and erosive power. There may then exist a mutual self-stabilization of the waves amplitude together with the irregular morphology of the coast. A simple model of such stabilization is discussed. It leads, through a complex avalanche dynamics of the earth-sea interface, to the spontaneous appearance of an irregular sea-shore. The final coast morphology is found to depend on the morphology/damping coupling of the coast and on the possible existence of built-in correlations within the coast lithologic properties. In the limit case where the morphology/damping coupling is weak and when the earth lithology distribution exhibit only short range correlations, the process spontaneously build fractal morphologies with a dimension close to 4/3 [2]. This dimension refers to the dimension of the accessible perimeter in percolation theory. However, even rugged but non-fractal sea-coasts morphology may emerge for strong damping or during the erosion process. When the distributions of the lithologies exhibit long range correlations, a variety of complex morphologies are obtained which mimics observed coastline complexity, well beyond simple fractality. This approach, which links erosion of rocky coasts to percolation theory, provide a natural frame to explain the frequent field observation that the statistics of erosion events follow power law behavior. In a somewhat different perspective, the design of breakwaters is suggested to be improved by using global irregular geometry with features sizes of the order of the wave-length of the

A conflict model for the international hazardous waste disposal dispute.
Hu, Kaixian; Hipel, Keith W; Fang, Liping
2009-12-15
A multi-stage conflict model is developed to analyze international hazardous waste disposal disputes. More specifically, the ongoing toxic waste conflicts are divided into two stages consisting of the dumping prevention and dispute resolution stages. The modeling and analyses, based on the methodology of graph model for conflict resolution (GMCR), are used in both stages in order to grasp the structure and implications of a given conflict from a strategic viewpoint. Furthermore, a specific case study is investigated for the Ivory Coast hazardous waste conflict. In addition to the stability analysis, sensitivity and attitude analyses are conducted to capture various strategic features of this type of complicated dispute.

In tropical areas measles cases often are under-reported but the authors comment here two epidemics which had at first been considered as outbreaks of measles but were not. The first epidemic resembled a Chikungunya virus outbreak with important rashes, hyperthermia and pain attacks and was due to Igbo-Ora arbovirus. In the second epidemic children were having rashes with hyperthermia and adenopathy evoking rubella. The authors consider the possibility of over-reporting in view of the surveillance of measles, the target-disease in EPI (Expanded Programme on Immunization). This hypothesis is confirmed by the distribution of reported cases at national level with a high rate of out-season cases and among adults.
Rock coasts and seabird breeding sites : a common optimization
NASA Astrophysics Data System (ADS)
Marie, Eveillard-Buchoux
2014-05-01
The North-West coasts of Europe support a lot of part of Northern hemisphere breeding seabirds. In that context, Scotland has a preponderant place and Brittany has southernmost limit of these species areas, for most of them. Outside the breeding season these species live mainly on the open sea and when they do visit the land to breed, they nest on a specific sites : almost all the time they breed on the rock coasts, often on seacliffs. This specific habitat are defines by geomorphological characteristics which offer special forms of the coast. The forms of rock coasts are originally and different because of several proprieties of geology, of lithology, of structures. Breeding seabird, occupying these sites, reveals, in a new light, the richness of these forms and the originals geographic location of the coastline : seabirds prefer nest in exposed coastline like rock caps, rocky points or islands. Seabirds and rock coasts are research topics in environmental geography since several years. However, these combination studies is a new approach in this field and enlargement in the heritage field allows supplement scientific approach. For example, it show that in most important touristic sites, environmental protection measures focused on landscape, habitat or bird, but much more rarely on rock coasts for these intrinsic values. Indeed, in Brittany or in Scotland, seabirds are often stars species in lot of coastal nature reserves, where they're considered like greater ecological heritage. We could see it in touristic promotion field : bird is everywhere, cliff is mostly kept in the dark, as well in leaflets as in speech visitor's guides - without, for example, as a part of this landscape. In all cases, combination of these two heritages is extremely rare. Yet, this current research illustrates the interest and the issue of development of this comparative approach seabirds / rock coasts for optimization of nature tourism and geotourism.

It has been hypothesized that individuals adapted to conditions near the speciesâ range edge, may increase the likelihood that the species will persevere under changing climatic conditions (Rehm et al. 2015). The southern coast redwood (Sequoia sempervirens (D. Don) Endl.) forests vary from more northern redwood forests in terms of stand...
Uptake and elimination of poliovirus by West Coast oysters.
Di Girolamo, R; Liston, J; Matches, J
1975-02-01
Accumulation of poliovirus Lsc-2ab by West Coast oysters was determined by using a stationary seawater system, and depuration was determined by using both stationary and free-flow systems. Results indicate that these shellfish have the same pattern of accumulation and localization of viruses as do East Coast species. However, uptake appeared to occur more rapidly than described for East Coast shellfish. There appeared to be a gradual diffusion of virus from the digestive area into the body. Depuration was found to occur more rapidly and completely under free-flow conditions than in a stationary system.

Red tides (algae) bloomed late this summer along a 300-mile stretch of Texas' Gulf Coast, killing millions of fish and shellfish as well as making some people sick. State officials are calling this the worst red tide bloom in 14 years. The algae produces a poison that paralyzes fish and prevents them from breathing. There is concern that the deadly algae could impact or even wipe out this year's oyster harvest in Texas, which usually peaks during the Thanksgiving and Christmas holidays. The red tides were first observed off the Texas coast in mid-August and have been growing steadily in size ever since. Red tides tend to bloom and subside rapidly, depending upon changes in wind speed and direction, water temperature, salinity, and rainfall patterns (as the algae doesn't do as well in fresher water). This true-color image of the Texas Gulf Coast was acquired on September 29, 2000, by the Moderate-resolution Imaging Spectroradiometer (MODIS) flying aboard NASA's Terra spacecraft. The red tide can be seen as the dark reddish discoloration in the ocean running southwest to northeast along the coast. In this scene, the bloom appears to be concentrated north and east of Corpus Christi, just off Matagorda Island. The image was made at 500-meter resolution using a combination of MODIS' visible bands 1 (red), 4 (green), and 3 (blue). The city of Houston can be seen clearly as the large, greyish cluster of pixels to the north and west of Galveston Bay, which is about mid-way up the coastline in this image. Also visible in this image are plumes of smoke, perhaps wildfires, both to the north and northeast of Houston. For more information about red tides, refer to the Texas Red Tide Web site.

Intra-seasonal sea level variability along the west coast of India
NASA Astrophysics Data System (ADS)
Dhage, Laxmikant; Strub, P. Ted
2016-11-01
The importance of local versus distant forcing is studied for the wind-driven intra-seasonal (30-120 day) sea level anomaly (SLA) variations along the west coast of India. Significant correlations of altimeter-derived SLA on the west coast are found with the mid-basin SLA east of Sri Lanka and SLA as far as Sumatra and the equator, with increased lags, connecting with the remote forcing from the equator in the form of reflected Rossby waves. The highest correlations between SLA on the west coast and winds are found with the winds at the southern tip of India. Coherence calculations help to identify the importance of a narrow band (40-60 day) for the interactions of winds with the intra-seasonal SLA variations. A multivariate regression model, along with the coherences within this narrower band, suggest the lags of SLA on the west coast with winds to range from 0 to 2 days with the local forcing to 11-13 days with the forcing along south east coast of India. Hovmöller diagrams illustrate the propagation of signals by estimating phase speed for Rossby waves (57 cm/s) across the Indian Ocean from Sumatra and Coastal Trapped Waves (CTWs) along the west coast of India (178 cm/s). Propagation from the south-east coast of India is not as robust as Rossby waves from Sumatra.
On burst-and-coast swimming performance in fish-like locomotion.
Chung, M-H
2009-09-01
Burst-and-coast swimming performance in fish-like locomotion is studied via two-dimensional numerical simulation. The numerical method used is the collocated finite-volume adaptive Cartesian cut-cell method developed previously. The NACA00xx airfoil shape is used as an equilibrium fish-body form. Swimming in a burst-and-coast style is computed assuming that the burst phase is composed of a single tail-beat. Swimming efficiency is evaluated in terms of the mass-specific cost of transport instead of the Froude efficiency. The effects of the Reynolds number (based on the body length and burst time), duty cycle and fineness ratio (the body length over the largest thickness) on swimming performance (momentum capacity and the mass-specific cost of transport) are studied quantitatively. The results lead to a conclusion consistent with previous findings that a larval fish seldom swims in a burst-and-coast style. Given mass and swimming speed, a fish needs the least cost if it swims in a burst-and-coast style with a fineness ratio of 8.33. This energetically optimal fineness ratio is larger than that derived from the simple hydromechanical model proposed in literature. The calculated amount of energy saving in burst-and-coast swimming is comparable with the real-fish estimation in the literature. Finally, the predicted wake-vortex structures of both continuous and burst-and-coast swimming are biologically relevant.

Follicular aspiration versus coasting for ovarian hyper-stimulation syndrome prevention
Bushaqer, Nayla J.; Dayoub, Nawal M.; AlHattali, Khalsa K.; Ayyoub, Hisham A.; AlFaraj, Samaher S.; Hassan, Samar N.
2018-01-01
Objectives: To compare follicular reduction prior to human chorionic gonadotropin (HCG) trigger and coasting in terms of ovarian hyper-stimulation syndrome (OHSS) reduction, pregnancy, and cancellation rates in in vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI) cycles. Methods: This study was designed as a prospective study. The setting was the IVF unit at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia. A total of 39 patients undergoing IVF/ICSI cycles, who were at risk of OHSS, 20 were put into a coasting group and 19 had follicular reduction instead. This occurred between October 2010 and January 2011. Our main outcome was OHSS reduction. Results: Six (30%) women developed OHSS in the coasting group and 2 (10.5%) women developed OHSS in the follicular group (p-value=0.235). The pregnancy rates in the cycles were similar for both groups: 4/20 (20%) in the coasting group and 3/19 (15.8%) in the follicular group (p-value=1.000). The cancellation rate of the cycles was similar for both groups, 6/20 (30%) in the coasting group and 1/19 (5.3%) in the follicular group (p-value=0.09). The median number of punctured follicles was significantly lower in the follicular group (16 follicles, interquartile range (IQR)=21-12) compared to the coasting group (29 follicles, IQR=37.8-19.8, p-value=0.001). The retrieved, fertilized, and cleaved oocytes, as well as the number of embryos transferred, were similar amongst both groups. Conclusion: There was no difference between follicular reduction prior to HCG and coasting, in terms of OHSS reduction, pregnancy, and cancellation rates in both the IVF and ICSI cycles.

Influence of sea ice on Arctic coasts
NASA Astrophysics Data System (ADS)
Barnhart, K. R.; Kay, J. E.; Overeem, I.; Anderson, R. S.
2017-12-01
Coasts form the dynamic interface between the terrestrial and oceanic systems. In the Arctic, and in much of the world, the coast is a focal point for population, infrastructure, biodiversity, and ecosystem services. A key difference between Arctic and temperate coasts is the presence of sea ice. Changes in sea ice cover can influence the coast because (1) the length of the sea ice-free season controls the time over which nearshore water can interact with the land, and (2) the location of the sea ice edge controls the fetch over which storm winds can interact with open ocean water, which in turn governs nearshore water level and wave field. We first focus on the interaction of sea ice and ice-rich coasts. We combine satellite records of sea ice with a model for wind-driven storm surge and waves to estimate how changes in the sea ice-free season have impacted the nearshore hydrodynamic environment along Alaska's Beaufort Sea Coast for the period 1979-2012. This region has experienced some of the greatest changes in both sea ice cover and coastal erosion rates in the Arctic: the median length of the open-water season has expanded by 90 percent, while coastal erosion rates have more than doubled from 8.7 to 19 m yr-1. At Drew Point, NW winds increase shoreline water levels that control the incision of a submarine notch, the rate-limiting step of coastal retreat. The maximum water-level setup at Drew Point has increased consistently with increasing fetch. We extend our analysis to the entire Arctic using both satellite-based observations and global coupled climate model output from the Community Earth System Model Large Ensemble (CESM-LE) project. This 30-member ensemble employs a 1-degree version of the CESM-CAM5 historical forcing for the period 1920-2005, and RCP 8.5 forcing from 2005-2100. A control model run with constant pre-industrial (1850) forcing characterizes internal variability in a constant climate. Finally, we compare observations and model results to
Transformation of model data to information - experiences with coastDat
NASA Astrophysics Data System (ADS)
Meyer, E.; Weisse, R.
2016-02-01
The idea of coastDat is to improve the data base in sparse observational marine regions and to increase data homogeneity and consistency. In doing so long-term historical model data of e.g. wind (e.g. storms), wind wave and tide surge hindcasts are developed and proofed for regions like North Sea and Baltic Sea. These data-sets are available in hourly resolution and highly spatial resolution to simulate the marine environment from 1948/1958 up to now. Scenarios of potential future developments in a changing climate are also available. The coastDat data sets are used for applications e.g. offshore wind industry (design & logistics), risk analysis and analysis of pathways of energy transition. More than 80 stakeholders have used coastDat data sets. They are composed of science networks (31%), economic actors (45 %) and administrating policy actors (14%). The idea of coastDat is compatible in other coastal regions. Also coastDat is suitable as an information base in order to develop possible future adaptation measures. Here the data set and the history are briefly described, validation is reviewed, and an overview about recent uses of the data is provided.

Background In resource-limited settings where nevirapine-containing regimen is the preferred regimen in women, data on severe adverse events (SAEs) according to CD4 cell count are limited. We estimated the incidence of SAEs according to CD4 cell count and identify their risk factors in nevirapine-treated women. Methods All HIV-infected women who initiated nevirapine-containing regimen in the MTCT-Plus operational program in Abidjan, Côte d'Ivoire, were eligible for this study. Laboratory and clinical (rash) SAEs were classified as grade 3 and 4. Cox models were used to identify factors associated with the occurrence of SAEs. Results From August 2003 to October 2006, 290 women initiated a nevirapine-containing regimen at a median CD4 cell count of 186 cells/mm3 (IQR 124-266). During a median follow-up on treatment of 25 months, the incidence of all SAEs was 19.5/100 patient-years. The 24-month probability of occurrence of hepatotoxicity or rash was not different between women with a CD4 cell count >250 cells/mm3 and women with a CD4 cell count ≤250 cells/mm3 (8.3% vs. 9.9%, Log-rank test: p = 0.75). In a multivariate proportional hazard model, neither CD4 cell count >250 cells/mm3 at treatment initiation nor initiation NVP-based regimen initiated during pregnancy were associated with the occurrence of SAEs. Conclusion CD4 cell count >250 cells/mm3 was not associated with a higher risk of severe hepatotoxicity and/or rash, as well as initiation of ART during pregnancy. Pharmacovogilance data as well as meta-analysis on women receiving NVP in these settings are needed for better information about NVP toxicity. PMID:20576111

Coast Guard Assists with Mapping of Great Lakes Ice
1976-11-21
A group of Coast Guard seamen leave their ship to verify ice formations on the Great Lakes as part of an joint effort with the National Aeronautics and Space Administration (NASA) Lewis Research Center and the National Oceanic and Atmospheric Administration. The regular winter freezing of large portions of the Great Lakes stalled the shipping industry. Lewis began working on two complementary systems to monitor the ice. The Side Looking Airborne Radar (SLAR) system used microwaves to measure the ice distribution and electromagnetic systems used noise modulation to determine the thickness of the ice. The images were then transferred via satellite to the Coast Guard station. The Coast Guard then transmitted the pertinent images by VHF to the ship captains to help them select the best route. The Great Lakes ice mapping devices were first tested on NASA aircraft during the winter of 1972 and 1973. The pulsed radar system was transferred to the Coast Guard’s C-130 aircraft for the 1975 and 1976 winter. The SLAR was installed in the rear cargo door, and the small S-band antenna was mounted to the underside of the aircraft. Coast Guard flights began in January 1975 at an altitude of 11,000 feet. Early in the program, teams of guardsmen and NASA researchers frequently set out in boats to take samples and measurements of the ice in order to verify the radar information.
The influence of pigmentation patterning on bumblebee foraging from flowers of Antirrhinum majus
NASA Astrophysics Data System (ADS)
Whitney, Heather M.; Milne, Georgina; Rands, Sean A.; Vignolini, Silvia; Martin, Cathie; Glover, Beverley J.
2013-03-01
Patterns of pigmentation overlying the petal vasculature are common in flowering plants and have been postulated to play a role in pollinator attraction. Previous studies report that such venation patterning is significantly more attractive to bee foragers in the field than ivory or white flowers without veins. To dissect the ways in which venation patterning of pigment can influence bumblebee behaviour, we investigated the response of flower-naïve individuals of Bombus terrestris to veined, ivory and red near-isogenic lines of Antirrhinum majus. We find that red venation shifts flower colour slightly, although the ivory background is the dominant colour. Bees were readily able to discriminate between ivory and veined flowers under differential conditioning but showed no innate preference when presented with a free choice of rewarding ivory and veined flowers. In contrast, both ivory and veined flowers were selected significantly more often than were red flowers. We conclude that advantages conferred by venation patterning might stem from bees learning of their use as nectar guides, rather than from any innate preference for striped flowers.

Background In Côte d’Ivoire, a TB prison program has been developed since 1999. This program includes offering TB screening to prisoners who show up with TB symptoms at the infirmary. Our objective was to estimate the prevalence of pulmonary TB among inmates at the Correctional and Detention Facility of Abidjan, the largest prison of Côte d’Ivoire, 16 years after this TB program was implemented. Methods Between March and September 2015, inmates, were screened for pulmonary TB using systematic direct smear microscopy, culture and chest X-ray. All participants were also proposed HIV testing. TB was defined as either confirmed (positive culture), probable (positive microscopy and/or chest X-ray findings suggestive of TB) or possible (signs or symptoms suggestive of TB, no X-Ray or microbiological evidence). Factors associated with confirmed tuberculosis were analysed using multivariable logistic regression. Results Among the 943 inmates screened, 88 (9.3%) met the TB case definition, including 19 (2.0%) with confirmed TB, 40 (4.2%) with probable TB and 29 (3.1%) with possible TB. Of the 19 isolated TB strains, 10 (53%) were TB drug resistant, including 7 (37%) with multi-resistance. Of the 10 patients with TB resistant strain, only one had a past history of TB treatment. HIV prevalence was 3.1% overall, and 9.6%among TB cases. Factors associated with confirmed TB were age ≥30 years (Odds Ratio 3.8; 95% CI 1.1–13.3), prolonged cough (Odds Ratio 3.6; 95% CI 1.3–9.5) and fever (Odds Ratio 2.7; 95% CI 1.0–7.5). Conclusion In the country largest prison, pulmonary TB is still 10 (confirmed) to 44 times (confirmed, probable or possible) as frequent as in the Côte d’Ivoire general population, despite a long-time running symptom-based program of TB detection. Decreasing TB prevalence and limiting the risk of MDR may require the implementation of annual in-cell TB screening campaigns that systematically target all prison inmates. PMID:28759620

In this paper the authors report on recent radar measurements taken during the month of October 1994 with the LDG HF radar in the Ivory Coast, Africa as part of the International Equatorial Electrojet Year. The purpose of this experimental effort in part was to study the effects of thunderstorms on the ionosphere. At the same time, the authors decided to carry out a set of experiments of an exploratory nature to look for echoes that could potentially arise from ionization produced in the mesosphere. The two leading candidates for producing transient ionization in the mesosphere are meteors and high-altitudemore » discharges. Each is discussed in the context of these measurements.« less
Zhamanshin and Aouelloul - Craters produced by impact of tektite-like glasses?
NASA Technical Reports Server (NTRS)
O'Keefe, John A.
1987-01-01
It is shown that the enhanced abundance of siderophile elements and chromium in tektite-like glasses from the two impact craters of Zhamanshin and Aouelloul cannot be explained as a result of contamination of the country rock by meteorites nor, probably, comets. The pattern is, however, like that found in certain Australasian tektites, and in Ivory Coast tektites. It is concluded, in agreement with earlier suggestions by Campbell-Smith and Hey, that these craters were formed by the impact of large masses of tektite-like glass, of which the glasses which were studied are fragments. It follows that it is necessary, in considering an impact crater, to bear in mind that the projectile may have been a glass.

This paper reports on horizontal drilling in the Cretaceous Austin chalk of Texas which dominates news of U.S. Gulf Coast horizontal action. In spite of a significant decline in horizontal drilling in Texas-the Texas Railroad Commission reported a 15 unit decline in the number of permits to drill horizontal wells during the third quarter-operators in East and South Texas continue to expand plays and develop new ones. The Cretaceous Bruda may be gaining some respect as a horizontal target in Texas. Elsewhere on the Gulf Coast, Mississippi soon will see more action on the horizontal drilling front.

Intensification of upwelling along Oman coast in a warming scenario

The oceanic impact of poleward shift in monsoon low-level jet (MLLJ) is examined using a Regional Ocean Modeling System (ROMS). Two sets of downscaling experiments were conducted using ROMS with boundary and initial conditions from six CMIP5 models. While outputs from the historical run (1981-2000) acts as forcing for the first, the second uses RCP8.5 (2080-2099). By comparing the outputs, it is found that Oman coast will experience an increase in upwelling in tune with MLLJ shift. Consistent with the changes in upwelling and zonal Ekman transport, temperature, salinity, and productivity show significant changes near the Oman coast. The changes in MLLJ causes the coastal wind to angle against the Oman coast in such a fashion that the net upwelling increases in the next century and so does the marine productivity. This study contrasts the general view of weakening of upwelling along the Arabian coasts due to the weakening of monsoon winds.
Probabilistic estimation of dune retreat on the Gold Coast, Australia
Palmsten, Margaret L.; Splinter, Kristen D.; Plant, Nathaniel G.; Stockdon, Hilary F.
2014-01-01
Sand dunes are an important natural buffer between storm impacts and development backing the beach on the Gold Coast of Queensland, Australia. The ability to forecast dune erosion at a prediction horizon of days to a week would allow efficient and timely response to dune erosion in this highly populated area. Towards this goal, we modified an existing probabilistic dune erosion model for use on the Gold Coast. The original model was trained using observations of dune response from Hurricane Ivan on Santa Rosa Island, Florida, USA (Plant and Stockdon 2012. Probabilistic prediction of barrier-island response to hurricanes, Journal of Geophysical Research, 117(F3), F03015). The model relates dune position change to pre-storm dune elevations, dune widths, and beach widths, along with storm surge and run-up using a Bayesian network. The Bayesian approach captures the uncertainty of inputs and predictions through the conditional probabilities between variables. Three versions of the barrier island response Bayesian network were tested for use on the Gold Coast. One network has the same structure as the original and was trained with the Santa Rosa Island data. The second network has a modified design and was trained using only pre- and post-storm data from 1988-2009 for the Gold Coast. The third version of the network has the same design as the second version of the network and was trained with the combined data from the Gold Coast and Santa Rosa Island. The two networks modified for use on the Gold Coast hindcast dune retreat with equal accuracy. Both networks explained 60% of the observed dune retreat variance, which is comparable to the skill observed by Plant and Stockdon (2012) in the initial Bayesian network application at Santa Rosa Island. The new networks improved predictions relative to application of the original network on the Gold Coast. Dune width was the most important morphologic variable in hindcasting dune retreat, while hydrodynamic variables, surge and

The United Stated Geological Survey (USGS) Multi-Hazards Demonstration Project (MHDP) is preparing a new emergency-preparedness scenario, called ARkStorm, to address massive U.S. West Coast storms analogous to those that devastated California in 1861-62. Storms of this magnitude are projected to become more frequent and intense as a result of climate change. The MHDP has assembled experts from the National Oceanic and Atmospheric Administration (NOAA), USGS, Scripps Institute of Oceanography, the State of California, California Geological Survey, the University of Colorado, the National Center for Atmospheric Research, and other organizations to design the large, but scientifically plausible, hypothetical scenario storm that would provide emergency responders, resource managers, and the public a realistic assessment of what is historically possible. The ARkStorm patterns the 1861 - 1862 historical events but uses modern modeling methods and data from large storms in 1969 and 1986. The ARkStorm draws heat and moisture from the tropical Pacific, forming Atmospheric Rivers (ARs) that grow in size, gain speed, and with a ferocity equal to hurricanes, slam into the U.S. West Coast for several weeks. Using sophisticated weather models and expert analysis, precipitation, snowlines, wind, and pressure data the modelers will characterize the resulting floods, landslides, and coastal erosion and inundation. These hazards will then be translated into the infrastructural, environmental, agricultural, social, and economic impacts. Consideration will be given to catastrophic disruptions to water supplies resulting from impacts on groundwater pumping, seawater intrusion, water supply degradation, and land subsidence. Possible climate-change forces that could exacerbate the problems will also be evaluated. In contrast to the recent U.S. East and Gulf Coast hurricanes, only recently have scientific and technological advances documented the ferocity and strength of possible future

Due to their genetic proximity, chimpanzees share with human several diseases including bacterial, fungal and viral infections, such as candidiasis, acquired immune deficiency syndrome (AIDS), Ebola virus disease. However, in its natural environment, chimpanzees are tolerant to several pathogens including simian immunodeficiency virus (SIV), virus related to human immunodeficiency virus (HIV) that contribute to the emergence of opportunistic diseases such as microbial infections. Twenty seven species of plants consumed by chimpanzees were evaluated for their antimicrobial potential against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Candida albicans, Candida tropicalis and Candida glabrata using the agar diffusion technique and micro-dilution in 96-well plates. In total 132 extracts (33 dichloromethane, 33 methanol, 33 ethyl acetate and 33 aqueous) were tested. The results showed that 24 extracts (18 %) showed activity against bacteria and 6 extracts (5 %) were active against yeasts. The minimal inhibitory concentrations (MICs) values of active extracts ranged between 23 and 750 μg/ml for bacteria and between 188 and 1500 μg/ml for yeasts. Tristemma coronatum was the most promising on the studied microorganisms followed by Beilschmiedia mannii. The extracts of the two plants indicated by chimpanzees have potential for antimicrobial use in human.

Engineering geomorphology on the coast: lessons from west Dorset
NASA Astrophysics Data System (ADS)
Brunsden, Denys; Moore, Roger
1999-12-01
The central aim of this paper is to describe the general context in which an applied geomorphological investigation for a management project on a Heritage coast will be set. We attempt to show how the decisions may be affected by historical legacies and public or administrative attitudes. Modern attitudes to the coast in Great Britain are summarized in the light of recent studies by the Department of the Environment and the Ministry of Agriculture, Fisheries and Food. The Dorset coast in southwest England is used to illustrate the main points. The paper describes the coastal features, explains the historical legacy of use, and examines problems of contemporary coastal management. The paper concludes with a consideration of the natural geomorphological principles of landscape design which might be employed as part of the guiding concepts.
