Lymphome CĂ©rĂ©bral Primitif (LCP) du Sujet ImmunocompĂ©tent: A Propos dâUn cas Ă lâHĂŽpital National de Niamey (HNN)
Le Lymphome CĂ©rĂ©bral Primitif (LCP) du sujet immunocompĂ©tent est une entitĂ© rare des lymphomes Non Hodgkiniens en gĂ©nĂ©ral et des tumeurs cĂ©rĂ©brales en particulier. Il est caractĂ©risĂ© par sa sĂ©vĂ©ritĂ© clinique, mais aussi son mauvais pronostic. Nous rapportons un cas de LCP chez un sujet immunocompĂ©tent diagnostiquĂ© au service de neurologie et pris en charge au service dâOnco-hĂ©matologie de lâHĂŽpital National de Niamey.
Primary Cerebral Lymphoma (PCL) of the immunocompetent subject is a rare feature of non-Hodgkin's lymphoma in general and brain tumors in particular. It is characterized by its clinical severity, but also its poor prognosis. We report a case of LCP in an immunocompetent subject diagnosed in the neurology department and managed by Onco-hematology at the National Hospital of Niamey

Gestion intégrée de Maruca vitrata (FABRICIUS, 1787) et Megalurothrips sjostedti (TRYBOM, 1908), deux insectes ravageurs majeurs du niébé au Niger
Le niĂ©bĂ©, Vigna unguiculata (L.) Walp. est la principale lĂ©gumineuse cultivĂ©e au Niger. Câest une culture dâimportance Ă©conomique, sociale et alimentaire. Sa productivitĂ© est faible eu Ă©gard entre autres Ă la forte pression des bioagresseurs. La gestion intĂ©grĂ©e des ravageurs est lâune des stratĂ©gies adoptĂ©es pour accroĂźtre la productivitĂ© du niĂ©bĂ©. Lâobjectif de lâĂ©tude est de proposer un systĂšme de gestion intĂ©grĂ©e de Maruca vitrata et de Megalurothrips sjostedti, principaux ravageurs du niĂ©bĂ© au Niger. Lâessai est conduit sur deux diffĂ©rentes variĂ©tĂ©s du niĂ©bĂ©: la TN5-78 et la KVX908-1. Le dispositif expĂ©rimental utilisĂ© est un split plot avec quatre traitements et quatre rĂ©pĂ©titions. Le rĂ©sultat du suivi des effectifs des deux insectes a montrĂ© une prĂ©dominance de Megalurothrips sjostedti par rapport Ă Maruca vitrata sur la TN5-78 (607,25 et 15,25 individus, respectivement). Il en est de mĂȘme sur la KVX908-1, avec respectivement 307,25 et 17,5 individus. La comparaison de la densitĂ© des populations des ravageurs Ă©tudiĂ©s, montre quâelle est plus faible dans les parcelles traitĂ©es au Super-Diforce par rapport aux parcelles traitĂ©es avec le Neem et la prĂ©paration virale (MaviNPV). Dans lâensemble, le dispositif permet de rĂ©duire de façon significative la densitĂ© de Maruca vitrata et de Megalurothrips sjostedti. LâefficacitĂ© de la stratĂ©gie se traduit par lâobtention des rendements de 1,02 Ă 2,169 t/ha pour la variĂ©tĂ© TN5-78 et 1,96 Ă 3,06t/ha pour la KVX908-1.Mots clĂ©s : Lutte intĂ©grĂ©e, Maruca vitrata, Megalurothrips sjostedti, Vigna unguiculata, MaviNPV, Neem, insecticide chimiqu
EFFECT OF CUTTING HEIGHTS AND MINERAL NPK AND/OR BIOFERTILIZATION TREATMENTS ON MORINGA OLEIFERA, L. PLANTS
This study was conducted in Hort. Dept., Fac. Agric., Minia Univ. in the two successive seasons of 2015 and 2016 on Moringa to study the effect of cutting heights (10, 20, 30 and 40 cm) and fertilization on yield productivity and chemical constituents of the plants.
Data indicated that cut plant at 10 cm was superior than other treatments on increasing branch numbers, fresh and dry weights/plant/cut and total yield/plant/season, as well as, total carbohydrates, protein and vit. C %. All used six fertilization treatments significantly increased all vegetative growth parameters and chemical constituents as compared with control. The best treatments were NPK (100 %) and bio. + 75 % NPK.
It could be recommended to cut Moringa oleifera at 10 cm above soil surface and fertilizing plants with bio. + 75 % NPK dose to obtain a good production biomass and high quality

Peste des petits ruminants (ppr) thermotolerant vaccine production and delivery through a public-private partnership in the Sahel: The case of Mali
Instabilities in extreme magnetoconvection
Thermal convection in an electrically conducting fluid (for example, a liquid
metal) in the presence of a static magnetic field is considered in this
chapter. The focus is on the extreme states of the flow, in which both buoyancy
and Lorentz forces are very strong. It is argued that the instabilities
occurring in such flows are often of unique and counter-intuitive nature due to
the action of the magnetic field, which suppresses conventional turbulence and
gives preference to two-dimensional instability modes not appearing in more
conventional convection systems. Tools of numerical analysis suitable for such
flows are discussed
Correction: Technical efciency in banks: a review of methods, recent innovations and future research agenda
Reversible and Irreversible Interactions of Poly(3-hexylthiophene) with Oxygen Studied by Spin-Sensitive Methods
Understanding of degradation mechanisms in polymer:fullerene
bulk-heterojunctions on the microscopic level aimed at improving their
intrinsic stability is crucial for the breakthrough of organic photovoltaics.
These materials are vulnerable to exposure to light and/or oxygen, hence they
involve electronic excitations. To unambiguously probe the excited states of
various multiplicities and their reactions with oxygen, we applied combined
magneto-optical methods based on multifrequency (9 and 275 GHz) electron
paramagnetic resonance (EPR), photoluminescence (PL), and PL-detected magnetic
resonance (PLDMR) to the conjugated polymer poly(3-hexylthiophene) (P3HT) and
polymer:fullerene bulk heterojunctions (P3HT:PCBM; PCBM =
[6,6]-phenyl-C61-butyric acid methyl ester). We identified two distinct
photochemical reaction routes, one being fully reversible and related to the
formation of polymer:oxygen charge transfer complexes, the other one,
irreversible, being related to the formation of singlet oxygen under
participation of bound triplet excitons on the polymer chain. With respect to
the blends, we discuss the protective effect of the methanofullerenes on the
conjugated polymer bypassing the triplet exciton generation
Technical efficiency in banks: a review of methods, recent innovations and future research agenda
Technical efficiency in banking is a critical aspect of the financial industry and has been widely studied using various measurement techniques. This systematic literature review offers a comprehensive examination of 305 studies on the application of technical efficiency measurement techniques in both Islamic and conventional banking sectors from 1989 to 2019. Our comprehensive analysis not only provides a broad view of the efficiency measurement literature but also outlines a future research agenda. Despite the extensive research in this field, several issues remain unresolved, including inputâoutput selection, a comparison of efficiency between Islamic and conventional banks, limited cross-country studies, and a lack of exploration into the impact of regulation and Shariah principles. To address these gaps, this review highlights the most commonly used methods, variables, and findings and provides three key recommendations for future research. Three key themes emerge from our examination. First, there is a need to better understand and the application of new frontier techniques other than the traditional methods, which currently dominate the existing literature. Second, the intermediation approach is the most frequently used in variable selection, thus more studies with comparative findings with applications of production and value-added approaches are suggested. Third, the most frequently used input variables are âlaborâ, âdepositsâ and âcapitalâ, whilst âloansâ and âother earning assetsâ are the most popular output variables. We recommend three vital directions for future research: (i) non-interest expenses to be included amongst the inputs, while non-interest income should be added to the list of outputs, especially when estimating efficiency scores of Islamic banks. (ii) The impact of environmental variables such as, inter alia, Shariah principles, country-specific factors, and management quality is suggested to be considered simultaneously in models measuring and comparing the efficiency of Islamic and conventional banks. (iii) The selection of performance metrics employed should be expanded to include both the standard efficiency scores and the Malmquist Total Factor Productivity Index (TFP). The paper concludes with research needs and suggests directions for future research
