Contemporary francophone west African social movements in the rise of neo pan-africanism: a case study of y en a marre in Senegal.

The emergence of the Y en a marre movement in 2011 has reshaped the face of social activism in Francophone sub-Saharan Africa. In less than a decade of its existence, Y’en a marre has become iconic in Senegalese civil society and beyond. Their effective opposition to the Wade regime between 2011 and 2012 reverberated beyond the Senegalese border through their slogan “touche pas à ma constitution” (Do not touch my constitution), a rallying cry that young people in Burkina Faso and the Democratic Republic of Congo later appropriated, thus giving the movement a Pan-African platform. The birth of Y’en a Marre and its confrontation methods (street protests, verbal attacks via radio, TV, concerts, rap sons to name a few) enabled several important interrogations that this project aims at exploring. What triggers the formation of social movements in contemporary Senegal and Francophone West Africa? How does Y’en a Marre’s blueprint fit in the general struggle for Pan-Africanism today? How are music and art used to create a transnational solidarity against bad governance and foreign influence in West African affairs? This dissertation explores how contemporary social movements in Francophone West Africa are re-appropriating Pan-African principles to fight for democracy and good governance as well as to curb foreign influence in African affairs. This dissertation argues that such movements use various innovative means including music, visual art, social media, and street protests to draw popular support and foment resistance to confront regimes that fail to safeguard basic democratic principles, such as fair and transparent elections. In doing so, social movements in Francophone West Africa help foster a new era in the development of Pan-Africanism called “Neo Pan-Africanism” in which social activist and popular movements become one of the key driving forces of Pan-Africanism as a transatlantic movement and ideology. The dissertation also contends that the Y’en a marre movement is spearheading a new type of transnational collaboration partly grounded in popular culture (especially hip-hop), advocacy training and sometimes litigation, to enable social movements in West Africa to fight against common issues that pertain to the safeguard of their national sovereignties

Effets de la fertilisation organo- minérale sur la croissance et le rendement du « mil sanio » (Pennisetum glaucum L. R. Br) en Haute Casamance (Sénégal)

La présente étude vise à identifier le meilleur plan de fumure organominérale pour une bonne production en grains du mil Sanio au Sud du Sénégal. Un dispositif expérimental en split-plot avec 03 répétitions a été mis en place. Le facteur principal est la fertilisation minérale (FM) avec quatre niveaux (FM1, FM2, FM3 et FM4) et le facteur secondaire, l’amendement organique (AO) avec trois traitements (AO1, AO2 et AO3). Les résultats ont montré qu’à maturité les tailles des plantes les plus élevées ont été obtenues avec les apports AO3 (291,1 cm) et FM4 (284,2 cm). Le tallage le plus important a été noté avec le traitement FM4 (15 talles/poquet). Des gains respectifs de 26%, 32% et 56% du rendement en biomasse aérienne sèche sont obtenus avec l’augmentation des doses d’engrais minéral. Les rendements en grains les plus élevés sont obtenus avec les apports FM2 et FM4 avec des taux d’accroissements respectifs de 37,1% et 62,3% par rapport au témoin non fertilisé. Dans le cadre de l’amélioration durable de la productivité du mil sanio en Haute Casamance, l’association AO2 et FM2 d’engrais minéral serait une pratique à vulgariser. This study aims to identify the best organo-mineral fertilization plan for a good grain production of sanio millet. The experiment was laid out in a split-plot design with three repetitions. The main factor is the mineral fertilization (FM) with four levels (FM1, FM2, FM3 and FM4) and a secondary factor, the organic amendment (AO) with three treatments (AO1, AO2 and AO3). The results showed that at maturity the highest plant sizes were obtained with AO3 (291.1 cm) and FM4 (284.2 cm) inputs. The most important tillering was noted with the FM4 treatment (15 tillers / pouch). Increase respective of 26%, 32% and 56% of biomass production were obtained with the increase of the mineral fertilizer doses. The highest grain yields are obtained with the FM3 and FM4 inputs with respective growth rates of 37.1% and 62.3% compared to the control. In the context of the sustainable management of the productivity of the sanio millet in Casamance higher land, the the combination of AO2 and FM2 of mineral fertilizer could be advised to farmers

The synthesis and the reactivity of arene ruthenium oxalato complexes

This article outlines the reactions of the well known [RuCl(η6-p-cymene)]2(μ-η4-C2O4) and [RuCl(η6-p-cymene)(η2-dppm)][PF6] ruthenium complexes with C2O4(Me4N)2 in the mol ratios 1:1 and 2:1. While the 2:1 ratio reaction led to the sole and expected binuclear product {[Ru(η6-p-cymene)(η2-dppm)]2(μ-η2-C2O4)}[PF6]2, the reaction also afforded the unexpected mononuclear complex [RuCl(η2-C2O4)(η6-p-cymene)][Me4N]. This can also be obtained in improved yield by reacting [RuCl2(p-cymene)]2 with C2O4[Me4N]2 in a 1:1 mol ratio. Surprisingly, when [RuCl(η6-p-cymene)]2(μ-η4-C2O4) was reacted with an equimolar amount of the ligand dppm, the expected complex {[Ru(η6-p-cymene)]2(μ-η4-C2O4)(μ-dppm)}[PF6]2 was accompanied by [RuCl(η6-p-cymene)(η2-dppm)][PF6] in an inseparable solid mixture. KEY WORDS: Ruthenium, Arene, p-cymene, Mesitylene, Oxalate, bis-(Dipenylphosphino)methane  Bull.

Right-heart infective endocarditis: apropos of 10 cases

The prevalence and characteristics of right heart endocarditis in Africa are not well known. The aim of this study was to describe the epidemiological, clinical and laboratory profiles of patients with right-heart infective endocarditis. This was a 10-year retrospective study conducted in 2 cardiology departments in Dakar, Senegal. All patients who met the diagnosis of right heart infective endocarditis according to the Duke's criteria were included. We studied the epidemiological, clinical as well as their laboratory profiles. There were 10 cases of right-heart infective endocarditis representing 3.04% of cases of infective endocarditis. There was a valvulopathy in 3 patients, an atrial septal defect in 1 patient, parturiency in 2 patients and the presence of a pacemaker in one patient. Anaemia was present in 9 patients whilst leukocytosis in 6 patients. The port of entry was found to be oral in three cases, ENT in one case and urogenital in two cases. Apart from one patient with vegetations in the tricuspid and pulmonary valves, the rest had localized vegetation only at the tricuspid valve. However, blood culture was positive in only three patients. There was a favorable outcome after antibiotic treatment in 4 patients with others having complications; three cases of renal impairment, two cases of heart failure and one case of pulmonary embolism. There was one mortality. Right heart infective endocarditis is rare but associated with potentially fatal complications.Pan African Medical Journal 2015; 2

Détermination De La Dose Optimale D'engrais Minéral 15-15-15 Sur Cinq (05) Variétés De Maïs Doux (Zea Mays L. ssp. saccharata) Au Sénégal

The objective of this study is to assess the response of five varieties of sweet maize namely, Prime plus (V1), Shy 1036 (V2), Colombus (V3), GSS (V4), and JKMH-45 (V5) to three different doses of NPK (15-15-15) fertilizer: F1 (normal dose), F2 (75% of the normal dose) and F3 (125% of the normal dose). An experimental design in Fisher blocs with 15 treatments was established at the ISRA/CRA experimental station in Saint Louis (Senegal). The results have shown that 30 days after sowing (DAS), the varieties Colombus, GSS and JKMH-45 have had the highest heights with 32.75 cm, 31.85 cm and 31.46 cm, respectively with the F2 dose. The variety JKMH-45 has a greater height of the upper ear (89.39 cm) at 60 DAS and valorizes better the F2 dose (75% of the normal dose). The F3 dose increases less the plant’s height. A non-significant difference was observed among the 5 varieties used regarding the precocity. The variety V2 or Shy 1036 developed ears at first, but is not precocious compared to the variety V1 that not only shows earlier anthesis but also an appearance of darker hairs. The variety JKMH-45, although presenting darker hairs after the variety Prime plus, is the latest variety, earing at 57 DAS and with male and female anthesis appearing at 59 DAS and 63 DAS. This study can constitute a basic criterion in differentiating the sweet maize varieties in Senegal. It would also allow more financial saving on inputs and contribute to the maximization ofproduction if the choice of the variety is well done

Profil epidemiologique de l’epilepsie chez des patients atteints de troubles du spectre de l’autisme: Etude de 45 cas a Dakar (Senegal)

Description: Troubles du spectre de l’autisme (TSA) et épilepsie peuvent coexister chez une même personne constituant des facteurs de mauvais pronostic bilatéraux. Objectif:  Décrire les éléments sociodémographiques de patients atteints de TSA et étudier les aspects clinico-paracliniques et évolutifs des épilepsies chez ces patients. Patients et Méthodes:  Etude transversale et descriptive au service pédopsychiatrique du CHNU Fann, avec analyse des dossiers, via un questionnaire standardisé, de tous les patients suivis entre Janvier 2004 et Septembre 2018 pour TSA avec ou sans épilepsie. Résultats:  Quarante-cinq patients avec TSA colligés, avec une fréquence de l’épilepsie de 37,8%. L’épilepsie avait débuté avant l’âge de 5 ans dans 94% des cas. Les crises étaient généralisées (58,8%), essentiellement motrices tonico-cloniques (80%), ou focales (35,3%), avec une fréquence de 2 crises/jour à 1 crise/semaine. L’EEG de veille et sommeil montrait des anomalies majoritairement frontales dans 60%, et centro-pariétales dans 26,6% des cas. L’imagerie cérébrale était normale dans 93,9% des cas, et les potentiels évoqués auditifs (PEA) normaux dans 87,2% des cas. La prise en charge était multidisciplinaire pour les TSA (neuropsychologique, psychomotrice, orthophonique) et médicale, essentiellement (82,4%) en monothérapie pour l’épilepsie. Les médicaments antiépileptiques utilisés étaient le valproate de sodium (58,8%) et le phénobarbital (17,6). Le niveau d’instruction était bas avec 40% de non-scolarisés et 55,6% au primaire. Seuls 6,7% étaient autonomes et 20 patients nécessitaient une aide quasi-constante. Conclusion: La prévalence de l’épilepsie chez les patients atteints de TSA varie suivant les études. Une prise en charge globale et multidisciplinaire de l’épilepsie et des TSA améliore les troubles de comportement.   English Title: Epidemiologic profile of epilepsy in patients with autism spectrum disorders: study of 45 cases in Dakar (Senegal) Description: Autism spectrum disorders (ASD) and epilepsy can coexist in the same person, which are factors of bilateral poor prognosis. Purpose: To describe the socio-demographic profile of ASD patients and to study the clinical, paraclinical and evolutive aspects of epilepsy among them. Patients and methods: We did a cross-sectional and descriptive study in the department of child psychiatry of Fann university hospital in Dakar. We analyzed patients’ files followed between January 2004 and September 2018 for autism’s spectrum disorders with or without epilepsy. We used a standardized survey with several items. Results: Forty-five patients with ASD were collected, with an epileptic frequency of 37.8%. Epilepsy had started before the age of 5 years in 94% of cases. Seizures were generalized (58.8%), mainly tonico-clonic (80%), or focal (35.3%), with a frequency of 2 seizures per day to 1 seizure per week. The awake and sleep EEG showed abnormalities mostly in frontal area in 60%, and centro-parietal in 26.6%. Brain imaging was normal in 93.9%, and auditory evoked potential (AEP) normal in 87.2%. Management was multidisciplinary for ASD (neuropsychological, psychomotor, speech therapy) and medical, mainly (82.4%) monotherapy for epilepsy. The main molecules were: sodium valproate (58.8%) and phenobarbital (17.6). The level of education was low with 40% of students out of school and 55.6% in primary school. Only 6.7% were self-reliant and 20 patients needed almost constant assistance. Conclusion: The prevalence of epilepsy in patients with ASD varies according to the studies. The global and multidisciplinary management of epilepsy and ASD improves behavioral disorders
