Proposal of a Framework to Assess International Aid Projects Implementation Readnesss: Important Factors to Consider During the Analysis
Bangaly Kaba,Koffi N’Da
Communications of the IBIMA , 2009,
Abstract: Project management is used as the main tool for administering aid in developing nations. Unfortunately, the success rate of development aid projects is relatively low. Several explanations have been given for these failures. Clarke (1999) emphasizes the necessity of using instruments and techniques to increase a project’s chance of success. As current techniques do not always meet the specific needs of development aid projects, particularly in the African context, we identify some important factors that should be taken into account to assess the likelihood of success of these projects before they are implemented.
Influence du braconnage sur le comportement de fuite du bubale (Alcelaphus buselaphus major Pallas, 1766) dans la zone de Warigué en C te d\'Ivoire: implication pour l\'organisation d\'une chasse sportive
DA Koffi, I Kone, Y Tano
Sciences & Nature , 2008,
Abstract: Le bubale Alcelaphus buselaphus major est une grande antilope fréquemment rencontrée dans la zone de Warigué, au nord de la C te d\'Ivoire. Le comportement de fuite, un indicateur de l\'état de frayeur des animaux a été décrit dans différentes zones à intensités de braconnage variables.. Il en ressort que les bubales ont une plus grande distance de fuite dans les zones de forte pression de braconnage que dans les zones non braconnées ou de faible pression de braconnage. Par contre dans les zones d\'intense activité de braconnage les bubales sont observables beaucoup plus près (120 mètres) que dans les zones de faible pression de braconnage (plus de 240 mètres). Pour échapper au braconnage, les bubales se laissent plus facilement découvrir en zones très braconnées, mais fuient très loin à la vue des observateurs. Dans ce contexte, la pratique de la chasse sportive sur le site requiert un équipement approprié, notamment des armes de longue portée et une approche de chasse à l\'aff t. Hartebeest (Alcelaphus buselaphus major) is a big antelope frequently met in the zone of Warigué in the north of Ivory Coast. Flight behaviour an indicator of fear in animals, was described in various zones with variable poaching intensity. Our results reveal that hartebeests have a longer flight distance in areas with huge poaching pressure than areas without or with low pressure. On the other hand in areas with intense poaching activity, these animals are observed much closer (120 meters) that in areas of low pressure (more than 240 meters). To avoid poaching, hartebeests are more easily let discover in poaching areas but flee very far human presence is detected. That is why practice of hunting game on the site will require suitable equipments in particular weapons with long range, and an approach of hunting by shooting from hides.
Alimentation à base de produits du papayer et maturation ovocytaire chez Achatina fulica (Bowdich, 1820) en C te d'Ivoire

Tropicultura , 2004,
Abstract: Diets Based on Papaya and Oocyte Ripening by Achatina fulica (Bowdich, 1820) in Ivory Coast. The gardens snail, Achatina fulica (Bowdich, 1820) is a species recently introduced in Ivory Coast but of which the crop (the collection) and consequently, its consumption is growing within the population. Its breeding becomes imperative. In experimental breeding condition out of the ground diets based on papaya (R1: leave; R2: fruit; R3: leave + fruit) are (quantity of laid eggs) and tiny (presence in more or less larger number of ripe oocytes in the ovotestis) observations show that R3 regime is the most appropriate. It could be then recommended as diet to those who would like to breed this species.

Abstract: Costal Upwelling Impact on the Abundance and Sizes of Blue Marlins (Makaira nigricans, Lacepède, 1802) Captures by Artisans Fishers in the Offing of Ivory Coast. This study concern blue marlins (Makaira nigricans, Lacepede 1802) landed by sea artisan fishers in Abidjan port (Ivory Coast) from February 2006 to January 2007. During the Great Warm Season (GWS) March-April-May, the surface temperature average is 28.61 °C. With a Fishing Effort (FE) of 3,874 canoes; 285 blue marlins have been landed. Their weigh average is 77.70 kg with a Capture by Unit Effort (CPUE) of 5.62 kg. During this warm season, 187 blue marlins (65.61 %) have their sizes between 105 and 200 cm against only 98 (34.39%) which exceeds 200 cm. During the Great Cold Season (GCS) july-august-september, the average temperature is 25.58 °C. With 7,338 canoes (FE) went in sea, 244 fishes have a average weigh of 140.36 kg and a CPUE of 4.23 kg. During this upwelling period, only 43 M. nigricans (17.62%) have their size between 105 and 200 cm, against 201 (82.38%) which measure more than 200 cm. Therefore these two seasons, sizes and weights variance analyze with the Test-t show respectively a p-value highly significant (p- value = 2,255 x 10 -15 < 5%) et (p- value = 7,508 x10 -12 < 5%).

American Journal of Analytical Chemistry (AJAC) , 2018, DOI: 10.4236/ajac.2018.97027
Abstract: This study aims at exploring arsenite (As (III)) removal from water using naturally available rocks (laterite, sandstone and shale) in C?te d’Ivoire. The study focused on the adsorbent dose, operating pH, contact time, initial arsenite concentration, and modelisation on the removal of arsenite by performing batch adsorption experiment with well water. The optimal dosage related to an initial As (III) concentration of 5 mg/L was about 50, 75 and 145 g/L for laterite, sandstone and shale respectively. Laterite has a better adsorption capacity in comparison to sandstone and shale. On the other hand, kinetic study reveals that the equilibrium times are 5 h for laterite, 3 h for sandstone and 8 h for shale. Results showed that laterite, sandstone and shale could remove the arsenic in groundwater at initial arsenic concentrations below 5 mg/L, satisfying the World Health Organization (WHO) standard for drinking water. Moreover, kinetics study showed that the overall adsorption rate of arsenite was described by the pseudo-second-order kinetic model.

Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.62023
Abstract: In the framework of liberalization policies, a market information service (SIM) was created in 2008 in Togo. This public service entrusted in collecting and disseminating information about the mercurial of agricultural products aimed to improve the spatial integration of agricultural markets through the development of arbitrage. This paper assesses the impact of price dissemination on the spatial integration of maize markets. To this end, the weekly retail maize prices collected from 13 markets for the period without service (2003-2007) and the period with service (2008-2012) are considered. The results show that the impact of price dissemination on the spatial integration of maize markets is mitigated. By reference to Lome, neither rural markets nor northern markets have significantly improved their level of long-term and short-term spatial integration. To improve the efficiency of the service, it is necessary to understand the need of the sector’s stakeholders in order to revise the current format of the market information service.

Theoretical Economics Letters (TEL) , 2017, DOI: 10.4236/tel.2017.72017
Abstract: This paper assesses firstly the impact of the level and the composition of public expenditures on growth and secondly the link between public investment and private investment in Togo. For this purpose, a neoclassical growth model and a private investment model were estimated using Two-Stage Least Squares. The findings highlight that during the period 1980-2013, the composition of public expenditures, contrarily to the level, had significant effect on economic growth. In fact, the public consumption had a negative impact whereas public investment had a positive impact on growth. Moreover, the study finds out that increasing public expenditures involves crowding-out effect on private investment. In the light of the results, the paper invites the Togolese government to change the composition of public expenditures by giving priority to the investment with careful arbitrage between private and public expenditures.

Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.513122
Abstract: A study on some physico-chemical and biological variables of water quality was conducted on a coastal river in Ivory Coast. It’s the first assessment on water quality state. Those coastal rivers actually play an important role in the physical, biological and hydrological exchange between lagoons and the sea. Unfortunately, they are not taken into account by the national monitoring for water quality (RNO-CI). The samples were collected along Boubo River body through three stations, in the south of Cote d’Ivoire, during two years. Results show sharp fluctuations of the concentration N-NO3- nitrate, N-NH4+ ammonium and chlorophyll a with more than 20% variation. However, small fluctuations were noted for temperature, pH and conductivity with 4% - 20%. Measures are generally inferior to the threshold for hazardous water class. But respective average concentrations of N-NO3-, P-PO43-, COD and BOD5 are above natural water threshold, representing 67% of the analyzed samples of P-PO43- and 100% of the other. These results show that the river is not exempt of pollution: 0.2 mg/l of P-PO43- and 0.9 mg/l of N-NO3- are the limits of appropriate siege for the proliferation of invasive aquatic plants (IAP).

World Journal of Cardiovascular Diseases (WJCD) , 2017, DOI: 10.4236/wjcd.2017.79027
Abstract: Objective: To determine the prevalence of the use of traditional medicine in?hypertensive patients and to identify the socio-demographic characteristics of these patients. Materials and Methods: This is a single cross-sectionalstudy with descriptive purpose that was carried out over a 4 month-period, from 1 January 2017 to 30 April 2017, in the outpatient department of the Heart Institute of Abidjan. It involved patients who consulted during this period for high blood pressure. An informed questionnaire was submitted to patients. A pre-test was performed on 20 patients prior to the start of the survey. Results: The prevalence was 34%, with a slight male predominance (52.4%). The average age of our patients was 51.7 years ± 20 years. Males (52.4%) and females (47.6%) were roughly in the same proportions in our study with a slight male predominance. Patients with a higher level of education used traditional medicine in 30.6% that is about one third of the cases. Nearly one third of the patients had a monthly income above 300,000 FCFA (28.5%). Almost half of the patients (45%) had social insurance coverage. Conclusion: The use of traditional medicine by hypertensive patients is a practice that exists and is growing rapidly. The profile of hypertensive patients using traditional medicine can be summarized as a young subject, a male with a higher education level, a high monthly income and social coverage. It is the place to insist on the therapeutic education of our hypertensive patients only way for a good control of the blood pressure figures.

Abstract: Objective: To describe the epidemiological and etiological features of heart failure with preserved ejection fraction in our context. Materials and Methods: This is a retrospective study that was carried out over a 12-monthperiod, from 1 January 2015 to 31 December 2015, in the hospitalization department of the Heart Institute of Abidjan. It was about patients hospitalized for heart failure who had received a dose of NT-proBNP and who had had an electrocardiogram, and a Doppler echocardiography. Heart failure with preserved ejection fraction (HFPEF) was defined from the symptoms and signs of heart failure, the level of NT-proBNP and from echocardiography data based on the left ventricular ejection fraction (LVEF) > 50%, the dilatation of the left atrium. The diastolic dysfunction of the left ventricle was assessed by the ratio E/E’ > 13. We defined as heart failure with decreased ejection fraction (HFDEF) symptoms and signs of heart failure and left ventricular dysfunction LVEF < 40%. A computer file was completed. It included epidemiological and etiological data. Results: The study involved sixty-four patients with heart failure with preserved ejection fraction out of 257 patients with heart failure that is a prevalence of 25%. The mean age was 57.3 ± 16 years. There was a male predominance that is 52% of cases. Congestive heart failure was predominant in 67%. NT-proBNP levels were 365 pg/ml on average. The average length of stay was 5.5 ± 3.1. Intra-hospital deaths were 4.6%. The etiologies are dominated by high
