The study of Birimian granitoids is of great importance because it allows us to understand the architecture of the West African crust and the processes that shaped it. In order to contribute to the improvement of knowledge on the geodynamic context of the emplacement of certain granitoids of the West African craton, this article addresses some essential problems of the Birimian, namely distinguishing the real nature of the magmas and the mechanisms that generated this Birimian crust. On the West African craton, there are intrusive granites in volcano-sedimentary furrows, in meta-sedimentary basins and granites that form batholiths separating these structures. To provide an answer to this scientific concern, we conducted a comparative study of the granitoids of the Comoé basin (Tiassalé region) and those of the large batholith of Ferkessédougou (Daloa region). From this study, it appears that these Birimian granitoids have been identified as granites, granodiorites and tonalites in the Tiassalé region while in Daloa, they are assimilated to anatexites and granites. They present very diverse aspects and contexts of emplacement: the granitoids of the Comoé basin have characteristics of type I granite, indicating direct crystallization of mantle magmas in a syntectonic emplacement, while in the Daloa region, some granitoids are magmatic, others migmatitic or metasomatic, reflecting a certain complexity relating to their genesis.

Hippopotamus bites are rare in medical consultations, despite several studies exposing their aggressive character. A case of a hippopotamus bite on the shoulder of a fisherman has been reported. In addition to the osteoarticular aspect representing a therapeutic problem, the infectious aspect was marked by sepsis, with a death in less than 48 hours. Based on this observation, a protocol for the initial management of large animal bites was submitted.

This study endeavour assesses agromorphological likeness between initial introductions and regenerated accessions at the International Coconut Genebank for Africa and the Indian Ocean (ICG-AIO) based in C?te d’Ivoire. Ten couples of parental (G0) and regenerated (G1) accessions of Tall coconut palms were analyzed using Principal Component Analysis (PCA) and Multiple Analysis of Variance (MANOVA) from 26 agromorphological characters. The main results showed a relative decrease in the expression of the phenotypical traits concerning the component of the fruit, height and vigor of the stem and yield of bunches and fruits after one regeneration cycle. But, a high proportion (69%) of studied characters from leaf, inflorescence and nut components showed likeness between G0 and G1 accessions. After one regeneration cycle, the controlled pollination method guarantees significant conservation of the expression of the majority of agromorphological traits. Consequently, regenerated accessions of Tall coconut palms can be used to pursue research and development programs in C?te d’Ivoire.

Study of Formic and Acetic Acids in the Air of Humid Savannah Case of Lamto (Côte d’Ivoire)

Atmospheric and Climate Sciences 2016年第2期6卷 254-266页

From January 1995 to December 2004, 860 rainwater samples were collected in the humid savannah of Lamto. Using the Henry’s law, we determined the content of formic and acetic acids in the air based on their concentrations in rainwater. The annual partial pressure of both formic and acetic acids over the decade is variable. It covers a range of 0.003 (1998) to 0.21 ppbv (1996) and 0.27 (1999) to 0.47 ppbv (1996) for formic and acetic acids respectively. Also, the partial pressure in the dry season is higher than that in the wet season. This difference is related to the enrichment of the organic acid content in the air by the various sources that produce these acids. One of the main sources of increment in organic acid is biomass burning. This biomass burning contributes between 21% and 51% to the formation of the two acids in the humid savannah of Lamto. Ultimately the average annual organic acidity varies from 40% to 60% over the ten years period.

High-Yielding and Carotenoid-Rich Clones Identification among Thirty-One Cassava Clones with Colored Flesh

引用

American Journal of Plant Sciences 2021年第9期12卷 1445-1458页

作者： N’Zue Boni Coulibaly Idriss Koudous koffi Kouamé Guillaume Essis Brice Sidoine Dibi Konan Evrard Brice Sie raoul Sylvère Centre National de Recherche Agronomique (CNRA) Baouké C&#244 te d’Ivoire Université Nangui Abrogoua UFR Sciences de la Nature Unité de Phytotechnie et Amélioration Génétique Abidjan 02 C&#244te d’Ivoire

Cassava is the second most important food crop produced and consumed in Côte d’Ivoire, after yam. White-fleshed varieties, which are low in total carotenoids, are widespread, while coloured-fleshed varieties (yellow to orange), carotenoid-rich, are rare. However, the consumption of carotenoid-rich cassava varieties could help to alleviate health problems related to vitamin A deficiency. This study aims to identify high agronomic performance, carotenoid-rich and versatile cassava varieties among 31 clones introduced from IITA. They were compared to three controls, Bocou2, Yacé and Bonou2, according to agronomic and technological parameters. Results found that out of the 31 clones, six (I082425, I084157, I084563, I085894, I083774 and I070520) were more productive than the control Bocou2 (46.01 ± 14.88 t·ha-1);the clone I083774 had the highest yield (55.88 ± 6.16 t·ha-1). Twenty-one clones had dry matter contents, ranging from 37% to 41%, significantly similar to Yacé control (42.70%). Thirteen clones had highest total carotenoid contents than the control Bocou2. Clones I084157 and I082425 recorded the highest total carotenoid contents with 17.57 ± 1.92 and 18.39 ± 1.19 μg·g-1 respectively. Overall 31 tested clones were fibrous to varying degrees while 27 clones had mild or neutral post-cooking flavours and 17 clones had poor cooking. The clone I084157 is the best compromise of agronomic and technological desired traits.

Background: Dysmenorrhea is a common symptom of gynecology that causes social and economic disruption in the lives of women who suffer from it. But many of them consider it inevitable and do not consult a health worker. Knowing the factors associated with this condition could help reduce its frequency and impact. Objective: To determine the prevalence and factors associated with dysmenorrhea in Benin in 2017. Method: This was a cross-sectional, descriptive and analytical study from 17 April to 17 May 2017. It involved 822 women aged 15 to 44 selected by a cluster sampling technique. Information on socio-demographic characteristics, functional signs, and medical care was collected using questionnaires. The relationship between these factors and dysmenorrhea was analyzed using the chi2 test. The protocol was accepted by the ethics

Morphological Diversity within <i>Pterocarpus erinaceus</i>Poir. (Fabaceae), an Overexploited Species in the Savannahs of Côte d’Ivoire

引用

American Journal of Plant Sciences 2019年第9期10卷 1675-1688页

作者： Koudougnon Alice Estère Goba Léonie Clémence Kouonon Kouamé Guillaume koffi Béket Sévérin Bony Issoumaila Diomandé raoul Sylvère Sié Laboratoire de Biologie et Amélioration des Plantes UFR Sciences of Nature Université Nangui Abrogoua Abidjan Cote d’Ivoire

Pterocarpus erinaceus is a high socio-economic tree of African savannahs. It is overexploited due to technological qualities of its wood, forage value and medicinal uses. The main objective of this study is the assessment of the morphological variability within this species in Cote d’Ivoire, in sight of rational management. Fourteen morphological traits were used to appraise the variability within 144 trees in production from six sites (Yalo, Moyenne Marahoué, Kahanso, Kouassi-Ndawa, Ouarigué and Téguirdouo). The results indicate that the variability reaches 6.60 for the height of the fruit and 45.99 for the weight of the fruit. The results reveal also that there are three morphological groups of P. erinaceus in Cote d’Ivoire. Of the four traits that revealed a distinction among the three morphotypes, only the width of leaves and the number of leaflets enabled their complete distinction. Trees of group 1 have long leaves with a high number of leaflets and large fruits. Trees of group 2 have small leaves with a reduced number of leaflets and large fruits. Then trees of group 3 have intermediate value of width of leaves and number of leaflet and small fruits. The three morphological groups could be useful for varietal selection of P. erinaceus in Cote d’Ivoire.
