Relations between Man and the Environment through the Analysis of the Symbolism of the Herbs and Trees in Caribbean Literature  [PDF]
Chali Jean-Georges
Open Access Library Journal (OALib Journal) , 2016, DOI: 10.4236/oalib.1102765
Abstract:
The question of representations of the forest world, trees and plants in the Caribbean literature is important in the understanding of the relationship between man and nature. This work deals with the study of literary texts which highlight this human-nature interaction serving as the writer’s base to establish the legitimacy of the literary discourse. It anchors this dialogue in reality and knowledge of the world which translates the relationship between man and his environment. The data recorded during this study allow us to develop this continuum between literature, the world perception in the oral tradition and biotope observation by the endogenous populations. The writer renders the syncretic dimension that serves as the basis of literary aesthetics through writing and the popular imagination.

Annales de Toxicologie Analytique , 2010, DOI: 10.1051/ata/2010001
Abstract: Objectif : La surveillance biologique et la recherche d’une exposition à des métaux ou à des métallo des font habituellement appel à leur dosage dans le sang et les urines. Cependant, en médecine légale, ces milieux ne sont pas toujours disponibles, il est de ce fait nécessaire d’utiliser d’autres prélèvements. Si les cheveux et les ongles sont des biomarqueurs permettant de mettre en évidence une exposition au long cours, ils peuvent être le siège d’une contamination externe. Aussi, il nous a semblé intéressant d’étudier la distribution des métaux dans les tissus. Méthode : à l’occasion d’une autopsie, nous avons réalisé le dosage de 34 éléments dans les principaux tissus : Li, Be, B, Al, V, Cr, Mn, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Rb, Sr, Mo, Pd, Ag, Cd, Sn, Sb, Te, Ba, La, Gd, W, Pt, Hg, Tl, Pb, Bi, U, chez 21 sujets des deux sexes agés de 19 à 57 ans. Les dosages ont été réalisés par plasma à couplage inductif équipé d’un détecteur de masse sur des échantillons congelés de divers organes : cerveau, c ur, rein, foie, poumon et muscle. Cinq cents milligrammes de tissus sont minéralisés à 70 °C avec de l’acide nitrique pur. Le minéralisat est dilué avant analyse (acide nitrique, butanol et triton) en présence d’étalons internes (indium et rhodium). Du foie de b uf d’origine chinoise dont les concentrations de métaux sont certifiées et des cheveux provenant de l’Institut national desanté publique du Canada comportant de nombreuses valeurs de référence ont été analysés. Les résultats obtenus dans les biopsies de foie et de peau dans un cas de fibrose systémique néphrogénique (FNS) sont présentés. Résultats : La linéarité est excellente dans une large gamme de concentrations avec une pente supérieure à 0,999 pour tous les éléments. Les limites de détection sont comprises entre 8 μg/g (U) et 30 ng/g (B). La fidélité intermédiaire et la reproductibilité sont respectivement inférieures à 5 % et 10 %. Tous les éléments présentent une distribution log-normale. La répartition de nombreux métaux est homogène dans les différents organes (B, U, Ni). Des concentrations élevées de Cd sont constatées dans le rein alors qu’elles sont beaucoup plus faibles dans les autres tissus. Les organes à fonction métabolique contiennent les teneurs les plus importantes de quelques éléments (Mn, Mo). Pour l’Al, les concentrations les plus fortes sont retrouvées dans le poumon, organe en contact avec le milieu extérieur. Ces résultats sont comparés aux rares données de la littérature. Le premier cas rapporté de NSF montre une teneur hépatique en Gd 20 000 fois plus élevée que celles
The experience of caring for a dying client with intellectual disabilities. A qualitative study with direct-caregivers  [PDF]
Hanneke J. W. Bulsink, Jean Jacques Georges
Open Journal of Nursing (OJN) , 2013, DOI: 10.4236/ojn.2013.38078
Abstract:

Background: Caregivers experience problems when caring for people with intellectual disabilities who are terminally ill. Aim: The aim of this study is to gain a deeper understanding of the experience of the caregiver when caring for a person with intellectual disabilities who is terminally ill and what influences this experience. Design: A qualitative research was carried out following the principles of Grounded Theory (GT) method, through fifteen interviews with caregivers in a living facility with continuous care. Results: The results show how caregivers strive to create meaningful moments for their client during the last period of his life. Since very few of the clients can clearly express their wishes and feelings, continuous observation is required of the caregivers for the interpretation of small signals of their clients. In that way, the appropriateness of their actions can be made certain. The results show that because of their involvement, caregivers are able to recognize clients’ signals. When a client is dying, the special atmosphere created on the ward contributes to coping with the situation and a positive experience. Conclusion: Direct-caregivers caring for a client with an intellectual disability who is terminally ill, experience an intense period of insecurity and also a special period meaningful when caring a dying client with intellectual disabilities. Their relationship with the client makes them to be more able to strive for client’s comfort. The results also show that some factors such as enough staff, clear and open communication with the physician and support of the manager contribute to the quality of palliative care on the ward.

Journal of Geoscience and Environment Protection (GEP) , 2017, DOI: 10.4236/gep.2017.513005
Abstract: Sustainable management of Ivory Coast’s freshwater reserve at a catchment scale is an essential way in the policies of land use sustainable management. Thus, the implementation of physical conceptual semi-distributed SWAT model required a good knowledge of the watershed and a large number of physic-chemical data available that have been prior adapted to Ivory Coast’s climatic and soil conditions. The whole simulation span was divided into calibration set (1982-1986) and validation set (1987-1990). The SUFI-2 algorithm was used for parameters optimization. The sensitivity analysis focused on 8 parameters related to runoff, soil, evaporation, main channel and groundwater. The performance criteria were based on the P-factor, R-factor and the two objective functions which are Nash-Sutcliffe coefficient and the coefficient of determination. Although Taabo river basin like African basins suffers from a significant lack of data, the objective functions showed the robustness of the model to climate variability. The calibration launched during a wet period gave objective functions higher than 0.7 while validation performed in less humid period gave performance criteria around 0.6. During the simulation period, Taabo river basin daily green water ranged from 0.044 to 50.257 mm/day with a total average of 3,090.9 mm per year. As for blue water, it is ranged from 0.032 to 0.552 mm/day with an annual total average of 29.19 mm.

Open Journal of Social Sciences (JSS) , 2016, DOI: 10.4236/jss.2016.410013
Abstract: The purpose of this study is to identify and analyze the social representations of primary school teachers in Gabon on the teaching of physical education (EPS). This qualitative study carried on 54 teachers (38 women and 16 men) focused on the school district of the Estuary. The studied variables were the professional training, knowledge of official texts, teaching materials used, the role of EPS in primary school, educational practices and evaluation of EPS of primary school in Gabon and challenges for the teaching of EPS. The results obtained indicated: 1) the scarcity of training and educational support (70% of reports); 2) ignorance of official teaching texts of the EPS in the primary division (88.9% of reports); 3) the presence of a monthly annual programming for teaching the discipline for +68.6% of teachers; 4) inadequate sports infrastructure, educational materials and documentation; 5) respect of the regulatory texts (64.8% of teachers); 6) lack of teaching method for the teaching of EPS (80% of sales); 7) non-participation in the competitions organized by FEGASS. These results show that in Gabon, the teaching of physical education and sports of primary cycle reveals many difficulties compared to other disciplines.

Advances in Physical Education (APE) , 2016, DOI: 10.4236/ape.2016.64040
Abstract: The aim was to assess effects of the rainy ambiance on body weight, haemodynamic and thermoregulatory parameters in Congolese football players during a competition season. Thirty two football players of first division participated in this survey. The mean age was 22.0 ± 1.7 years. They have been divided in 2 teams: team 1 (n = 16) and team 2 (n = 16). The level of practice was comparable between topics of the 2 teams. The team 1 has been opposed to the team 2 during 6 friendly meetings in rainy and non rainy ambient. Variations of body weight, blood pressure, rectal temperature, coetaneous temperature and internal temperature have been measured before and after every meeting. The results indicate significant variations of body weight between the 2 groups: -5.7% in rainy ambient versus -4.79% in non rainy ambient. The higher variations were recovered at players evolving in the middle of the land, notably in the compartment 2: -6.6% in rainy ambient versus -3.9% (non rainy ambient). Him of it was in the same way for systolic arterial pressure (p < 0.05), diastolic arterial pressure, pulse pressure, the higher variations (p < 0.05) were recovered at the level of compartment 3 (rainy ambient). The rectal temperature, as for it, underwent some meaningful variations (p < 0.05), the superior gaps being recorded at soccer doing meetings in rainy ambient: Δθrect = 7.7% versus 3.2% (no rainy ambient). With regard to the coetaneous temperature, the variations observed between the two teams during matches were 5.5% for the team 1 and 8.9% for team 2 during rainy weather versus 5.6% and 5.7% during no rainy weather. As for the internal temperature, it varied respectively from 5.3% and 8.9% in rainy weather for the 2 teams, whereas the rates of variation amounted to 5.6% and 5.8% in no rainy weather. The humidity of air, the rainwater in which evolves the player, has some specific influences on the physiological adaptations at football players in equatorial environment. In conclusion, these data must challenge trainers, the technical settings of clubs and the Congolese Federation of Soccer, in the setting of the organization and the scheduling of the championship and the various tournaments.
Relationship between Climate and Groundwater Recharge in the Besseke Watershed (Douala – Cameroon)  [PDF]
Feumba Roger, Ngounou Ngatcha Benjamin, Tabue Youmbi Jean Ghislain, Ekodeck Georges Emmanuel
Journal of Water Resource and Protection (JWARP) , 2011, DOI: 10.4236/jwarp.2011.38070
Abstract: In Douala, economic capital of Cameroon, annual rainfall and temperature from its meteorological station (latitude: 4o00'N; longitude: 9o43'E; elevation: 5.0 m) were obtained and analysed to investigate the impact of climate variability on groundwater recharge. The climate shows a strong evidence of changes towards persistent weather conditions. The region is mainly characterized by a mean inter-annual temperature of 27.4oC and influenced by the mount Cameroon (4095 m in elevation). A recent decrease in mean annual rainfall occurred since 1982. The average annual rainfall which was 4200 mm with about 220 days of rainfall from 1917 to 1937 has moved to 4049 mm for the period 1937-1957, to 3826 mm for the period 1968-1988 and to 3619 mm for the period 1971-2001. Between, 1997 and 2007, the total number of days of rainfall has not exceeded 220 (193 days of rainfall in 1998 and 216 days of rainfall in 1999). By using Gauss law on 31 years (1971-2001) of annual rainfall, one note that the value 2850 mm has 20% of luck to be not observed and the value 4219 mm has 20% of luck to be exceeded. Douala already suffers from water shortage not because of decrease of rainfall but due to quality of underground water and salty taste of the main river catched for water supply. Moreover, precipitation is considered as the main replenishment source of all water resources in the study area (watershed of Besseke). The calculated interannual groundwater recharge rate (potential recharge, not necessarily real) is about 9% compared to the interannual total precipitation received by this area located closer the Atlantic Ocean (Gulf of Guinea). Groundwater discharge from the aquifer occurs between November and March.
Evaluation of Groundwater Suitability for Domestic and Irrigational Purposes: A Case Study from Mingoa River Basin, Yaounde, Cameroon  [PDF]
Tabue Youmbi Jean Ghislain, Feumba Roger, Wethe Joseph, Ekodeck Georges Emmanuel, De Marsily Ghislain
Journal of Water Resource and Protection (JWARP) , 2012, DOI: 10.4236/jwarp.2012.45031
Abstract: A baseline study involving analyses of subsurface water samples from the Mingoa river basin (longitude: 11°30′E; latitude: 3°52′N) in migmatitic complex in Yaounde Cameroon (central Africa) was carried out to assess their suitability for drinking, domestic and agricultural purposes. Study results show that pH is ranged between 5.1≤ pH ≤ 5.8 and then, induces acidic waters. Groundwater samples are generally characterized by low conductivity values, of which 100% are within the range (55 ≤ EC ≤ 1500 μS/cm). The mean values of the major cations (Ca2+, Mg2+, Na+, K+) and anions (SO42– , Cl, HCO3 ) are all within the World Health Organization (WHO) standards. Two of the springs sampled have nitrate (NO3 ) contamination. Even though contamination and acidic waters exist in some of the springs, the majority of the springs are excellent for agricultural and domestic purposes. Assessment of the groundwater for agricultural irrigation revealed two main categories. These are low salinity-low sodicity (C1-S1) and medium salinity-low sodicity (C2-S1), using the US Salinity Laboratory (USSL) classification scheme. As much as all of the samples plotted in the “excellent to good” and “good to permissible” categories on the Wilcox diagram. The groundwater in the study area may therefore be regarded as good for irrigation activities. The major identifiable geochemical processes responsible for the evolution of the various ions are mineral weathering, chemical reactions and anthropogenic activities.
Nanotechnologies and Ethical Argumentation: A Philosophical Stalemate?  [PDF]
Georges A. Legault, Johane Patenaude, Jean-Pierre Béland, Monelle Parent
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.31004
Abstract:

When philosophers participate in the interdisciplinary ethical, environmental, economic, legal, and social analysis of nanotechnologies, what is their specific contribution? At first glance, the contribution of philosophy appears to be a clarification of the various moral and ethical arguments that are commonly presented in philosophical discussion. But if this is the only contribution of philosophy, then it can offer no more than a stalemate position, in which each moral and ethical argument nullifies all the others. To provide an alternative, we must analyze the reasons behind the prevailing individual and cultural relativism in ethics. The epistemological investigation of this stalemate position will guide us to the core problem of the relation between theory and action (“Part 1: From a conceptual to a speech act analysis of moral arguments”). The stalemate can be overcome from a pragmatic philosophical standpoint, which combines epistemology, philosophy of language—that is, the philosophy of speech acts—and practical reasoning—that is, reasoning about decision-making (“Part 2: Moral argumentation from a pragmatist perspective”). From this philosophical standpoint, it will be possible to show how philosophy can accompany and support the development of nanotechnologies (“Part 3: Philosophy and the evaluation of the development of nanotechnologies”).
