In the present study, PtRuCe/MWNTs nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (MOR). To characterize the nanocatalysts, TEM, XRD, EDS and XPS are investigated. Cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activ...

La langue noire villeuse est une condition bénigne. C'est une modification de la couleur de l'aspect de la langue qui devient noire, sale, avec des papilles filiformes allongées. Plusieurs facteurs sont impliqués: tabagisme, consommation excessive de café / thé, mauvaise hygiène bucco-dentaire, névralgie du trijumeau et certains médicaments. Nous rapportons un nouveau cas. Figure 1: langue noir...

Traditional economic analysis of markets with asymmetric information assumes that the uninformed agents account for incentives of the informed agents to distort information. We analyze whether investors in the stock market are able to account for such incentive distortions. Security analysts provide investors with information about investment opportunities by issuing buy and sell recommendation...

Lymphocytic hypothalamitis (LHT) is a rare disease characterized by pituitary dysfunction, autonomic instability, metabolic disturbances, and neuropsychiatric disorders. We report the case of a 30-year-old man found to have LHT that progressed despite treatment with methylprednisolone and intravenous immunoglobulin (IVIG). A literature review was conducted to identify prior studies pertaining t...

The present study records the first successful colonization of Mansonia annulata and describes colony maintenance with modification of rearing medium and host plants. Three species of Mansonia mosquitoes (Ma. uniformis, Ma. indiana and Ma annulifera) were successfully reared in ambient environments with adult emergence rates > 50%, while Ma. bonneae and Ma. dives yielded emergence rates > 30%. ...

A new method to estimate the moving-average (MA) coefficients of a stationary time series is proposed. The new approach is based on the modified Cholesky factorization of a consistent estimator of the autocovariance matrix. Convergence rates are established, and the new estimates are used in order to implement a MA-type sieve bootstrap. Finite-sample simulations corroborate the good performance...
