Journal of Cancer Therapy (JCT) , 2015, DOI: 10.4236/jct.2015.69088
Abstract: Background: We aim to review different factors associated with the relapse and the mortality in breast cancer patients in restricted-resource settings over a five-year period. Method: A retrospective cohort study including 133 women underwent breast cancer surgery was performed at the Surgical Oncology Unit of the Conakry University Hospital in Guinea. Socio-demographical characteristics, clinical information, treatment and data on relapse and survival were retrieved from medical files. Predictor factors of relapse were analyzed by using univariate and multivariate logistic regression. Factors associated with mortality were analyzed by Kaplan Meier survival and Cox models. Results: Breast cancer surgery was conservative in 13 cases (9.8%) and radical in 120 cases (90.2%). Five-year relapse was 33.8% ± 8.0% and the predictor factors of this relapse were age and stage III (p = 0.005). The overall 5-year mortality was 42.1% and the risk factors independently associated with death were body mass index (p = 0.01), origin of patients (p = 0.02), radiotherapy (p = 0.01) and cancer relapse (p = 0.001). Conclusion: The proportions of relapse and death were higher in breast cancer patients. The age and the stage of cancer at the time of surgery were the predictor factors of relapse. Body mass index, origin of patients, radiotherapy and cancer relapse were associated with death.

Open Journal of Radiology (OJRad) , 2018, DOI: 10.4236/ojrad.2018.83016
Abstract: Background: Tolosa Hunt Syndrome is an inflammatory condition of unknown etiology of the cavernous sinus and superior orbital fissure. Because of the difficulty in establishing histological evidence, his diagnosis is based on a set of arguments established by the International Headache Society. MRI allows indirect visualization of the granuloma and plays a key role in diagnosis and follow-up. Aim: To illustrate High-field MRI contribution in Tolosa-Hunt Syndrome (THS). Cases Presentation: Two patients, a 25-year-old female and a 40-year-old male were recruited in this retrospective case report study at the Radiology service of Fann University Hospital (Dakar Senegal). The first patient has been suffering from a right retro-orbital pain and diplopia for 2 months and the second from a painful oculomotor nerve palsy for 3 months. Blood tests, lumbar puncture, thyroid hormone levels and an infectious screen were done. Screening for converting enzymes, and serum antibodies were also done. They underwent a high field MRI (Siemens 1.5T) with T1, T2, FLAIR, T2*, diffusion B1000, TOF polygon, CISS 3D and T1 gadolinium sequences in the 3 planes space. No significant abnormality was detected in blood tests or CSF analysis. Screening for converting enzymes and serum antibodies screen were also negative. For each patient, MRI examinations showed a non tumoral thickening of the right cavernous sinus, suggesting a granulomatous involvement. Tolosa Hunt Syndrome was evoked firstly. They were put on corticotherapy at high doses with a spectacular regression of symptoms. The Criteria of the International Headache Society of THS were met in both patients. Conclusion: High-field MRI is a significant diagnostic tool in the assessment of painful ophthalmoplegia. It allows a direct visualization of the granuloma of the cavernous sinus and assesses its course throughout the disease.

International Journal of Geophysics , 2012, DOI: 10.1155/2012/603949
Abstract: We used sounding data of the Multidisciplinary Analysis of the African Monsoon experience in summer 2006 at continental and coastal sites of West Africa, respectively, to analyze the vertical profiles of relative humidity, temperature, dew point, and speed and wind direction for the JJAS rainy period. The vertical gradient method is applied to the profiles of some thermodynamic parameters estimated from sounding data to do a comparative study of the structure and thermal properties, moisture, and static stability of the atmospheric boundary layer of inland, coastal, and marine sites to show consistent differences related to geographic factors. In vertical profiles of relative humidity, the intensity is higher in Dakar than in Niamey particularly in the core of the season. There are dry intrusions in the low levels at the beginning and end of the season in Dakar, which do not exist in Niamey. The mixing layer on the continent during the day can reach a height greater than 1100 m, and the inversion layer height can exceed 1700 m. Therefore, the maximum thickness of the boundary layer is observed on the continent during the day, while at night the marine boundary layer is the thickest. The diurnal evolution shows that the mixing layer thickness decreases during the night over the continent but increases at the coast and at sea. In the night at the continental site there is a division of the mixing layer with a consistent residual mixing layer. Continental boundary layer is more unstable during the day, while at night it is the marine boundary layer that is more unstable than the coastal and inland ones.

Introduction The term boundary layer was first introduced in the literature by Prandtl and Lustig [1]. Since then, many authors such as Turner [2], Monin [3], Zeman [4] and more, recently, Cushman-Roisin and Beckers [5] have studied the detailed description. The atmospheric boundary layer (ABL) has been variously defined, but it is commonly recognized as the lower part of the atmosphere, which is strongly influenced by the presence of the earth’s surface and responds to surface forcing with a timescale of about one hour or less. The ABL is the place where many processes, such as turbulence, friction, dispersion, energy dissipation, and wind shear occur. These processes are poorly parameterized in atmospheric models. Several ABL studies have focused on the turbulence but also on the mixing process triggered by significant warming or cooling [6]. Within the ABL, the transport of various quantities (heat, pollution, moisture, momentum, etc.) is mainly
Pyramidal and Granule Cells Distribution through Hippocampal Fields: An Index for Sensory Information Processing  [PDF]

Abstract: Background: This work aims at investigating the histology of hippocampus formation as structural model of information processing. The study addressed the question whether the pattern of cellular type distribution within hippocampal fields could be used as support of information processing in the hippocampus. Method: Pyramidal-shaped neurons presenting both cytoplasm and nucleus outlined clearly were measured systematically on brain slides, using a light microscope connected to a microcomputer equipped with a scanner software for measuring particles. Morphological types of cells were identified following class sizes and their distribution determined through hippocampal fields. Results: A battery of statistical tests: Sturges’ classification, class sizes distribution around overall mean, Bartlett’s sphericity test, principal components analysis (PCA) followed by correlations matrix analysis and ANOVA allowed two cellular groups to be identified in the hippocampus: large and small pyramidal-shaped cells. Conclusion: The results show that sensory information processing in the hippocampus could be built on two classes of pyramidal neurons that differed anatomically with probably different physiological functions. The study suggests combination ensembles clustering large and small pyramidal cells at different rates, as fundamental signaling units of the hippocampus.
Multi-Scale Characteristics of Precipitation and Temperature over West Africa Using SMHI-RCA Driven by GCMs under RCP8.5  [PDF]

American Journal of Climate Change (AJCC) , 2017, DOI: 10.4236/ajcc.2017.63024
Abstract: In this paper, we use simulations from the Swedish Meteorological and Hydrological Institute (SMHI) regional climate model (RCM) version 3.5 (SMHI-RCA3.5) following a multi-GCM boundary forcing approach. The model is run at a horizontal resolution of 50 km on the CORDEX-AFRICA domain. Key characteristics of precipitation, mean temperature and its extremes (minimum and maximum temperature) have been investigated over West Africa and on 3 designed sub-domains, the Sahel (SAH), the Senegal-Gambia (SEN) and the Gulf of Guinea (GOG). The analysis covers a historical period 1981-2005 and two future time slices, an intermediate term (IT) 2031-2055 and a fat term (FT) 2071-2095, under the Representative Concentration Pathways 8.5 (RCP8.5). The regional climate model RCA, forced by the reanalysis ERA-Interim, 6 CMIP5 GCMs and their ensemble, reproduces realistically the climatology of precipitation and temperatures over West Africa. Compared to observed datasets GPCP for precipitation and CRU for temperature, the ensemble outperforms both other GCMs and the verification model (ERA-Interim). The major biases in precipitation are the early onset over the Sahel and the little dry season (LDS), from mid-July to mid-September over the Gulf of Guinea, and a few models either overestimate and/or reflect rather poorly. The strong warming in extreme temperatures (minimum and maximum) combined with the drying mainly over Western Sahel (SEN) found in this study will very likely impact notably a vital sector like agriculture, both during the near and far terms.
Imagination and Thematic Reality in the African Novel: A New Vision for African Novelists  [PDF]
Abdoulaye Hakibou
Advances in Literary Study (ALS) , 2018, DOI: 10.4236/als.2018.61002
Abstract: The present study on the topic “Imagination and thematic reality in the African novel: a new vision to African novelists” aims to show the limitation of the contribution of the African literary works to the good governance and development process of African countries through the thematic choices and to propose a new vision in relation to those thematic choices and to the structural organisation of those literary works. The study is carried out through the theory of narratology by Genette (1980) and the narrative study by Chatman (1978) as applied to the novels by Chinua Achebe, essentially on the notion of order by Genette and the elements of a narrative by Chatman. It is a thematic and structural analysis that helps the researcher to be aware of the limitation of the contribution of African fiction to the good governance of African States and their real development, for the reason that themes and the structural organisation of those works are past-oriented. In such a context, readers are supposed to decode the different messages so as to put forth the necessary behaviour from the depicted ones. But, when one compares the literary effort of the novelists with the actual positive change, one realises that the gap is still obvious. This brought the researcher to the proposal of a new thematic orientation that does not depict societal misbehaviour but rather builds an ideal society in which the character embodies what the African society should be, African society which is here our particular concern so as to be able to make up the challenge of globalisation. This is not to deny the “fictionality” of the novels, but to reinforce it with stories that are not only past-oriented. This change may constitute a new source of attraction for African future literary works.
Le Musée de la culture juive de Bratislava et les implications postcommunistes de son développement institutionnel The Israeli Philosophy and the War The Museum of Jewish Culture in Bratislava and the Post-communist Implications of its Institutional Development

Abstract: The central idea and the purported role which organize the work of a given Jewish museum clearly refer to the issues occupying its surrounding society with the greatest intensity or, alternatively, to the theme that could have the best chance of being digested by that society. Such issues may include the thematization of anti-Semitism or of the Holocaust, or may have a cultural mediating role. To what extent can we find a reflection of the Central-European Jewry’s multi-layered process of self-definition in the work of the Museum of Jewish Culture in Bratislava after 1989? Furthermore, to what extent does this process of self-definition follow the historical image conceived in the consciousness of the surrounding societies? What are the social conditions, the historical precursors and the future perspectives of these self-reflections? These are the questions to which I purport to find an answer in my article.
ROLUL POLITICILOR SOCIALE IN STATUL BUNASTARII
Cecilia DEME
Revista Transilvan? de ?tiin?e Administrative , 2006,
Abstract: One of the most controversial topics in the field of social policies is the future of the welfare state. Despite opinions that predict the “crisis” of the welfare state, one thing is for sure: It still remains the only suitable model for many states worldwide. Since the Second World War – when major welfare policies throughout Europe and USA started to develop – Romania has been a country where welfare was associated with the communist regime. After the changes that occurred in 1989 this topic was forgotten by the newly elected government. The wrong and inefficient economic measures, together with the carelessness of the succeeding Romanian governments led to an incomplete and poor social protection system.
The Management of KG Schools: The Case of Dilla University Community School  [PDF]
Dejene Deme Megersa
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1101538
Abstract: The purpose of this paper was to explore the management of kindergarten school of Dilla University with reference to the learning environment and the kind of pedagogy employed. To examine the issue under consideration, the study was guided by qualitative case study. Semi-structured interview was the dominant data collection tool. On the basis of their contributions to the study six participants were selected purposefully. The central research questions were, “To what extent the learning environment of Dilla University KG school is conducive to serve its purpose? What pedagogical challenges and opportunities are in place in the management of the school?” The study found that the learning environment is not child friendly. Besides, the play-oriented child driven pedagogy is not yet adequately materialized. More specifically, the study revealed that there was unfavorable learning environment; poor commitment; lack of supervisory support; absence of trainings and re-trainings; and inappropriate mode of assessment. In light of the findings there is a need for adequate pre-service and ongoing trainings to the practitioners. Besides, the supervisory practices should be handled by professionally competent supervisors. Finally, the creation and development of a playful and child-oriented learning environment have been proposed, along with suggestions for further empirical exploration.
