By using the criterions of sensibility of IUPAC, we had determinad the sensibility far chromic (III) and (VI) from solution of its differents salts. We found that ion chromic (VI) in the form ion chromate is much sensible than chromic (III).

The aim of this study was to evaluate diets enriched with vitamin E and organic selenium on the productive performance and meat quality of rainbow trout (Oncorhynchus mykiss). The study was carried out in the fish farm «El Ingenio» in Huancayo, Peru with 4200 juvenile trout (164 g of body weight) during 40 days. A basal diet (treatment 1), two levels of vitamin E (25 and 50 ppm) and three levels of organic selenium (0.15, 0.25 and 0.35 ppm) were used. In the study, 600 trout were assigned per each of the seven treatments, using three repetitions per treatment (n=200) in a completely randomized design. Body weight gain, feed conversion ratio, and protein efficiency ratio were evaluated. Besides, in the frozen meat content of vitamin E, selenium and total volatile basic nitrogen, and the oxidation state were determined. Data was processed by the analysis of variance, the Tukey multiple c...

El estudio se hizo en el Centro Piscícola «El Ingenio» en Huancayo, Perú, con 4200 truchas juveniles (164 g de peso) durante 40 días. Se trabajó con una dieta basal (tratamiento 1), dos niveles de vitamina E (25 y 50ppm y tres niveles de selenio orgánico (0.15, 0.25 y 0.35 ppm). Se asignaron 600 peces por cada uno de los siete tratamientos y se tuvo tres repeticiones por cada uno (n=200)en un diseño experimental completamente al azar. Se evaluó la ganancia de peso, conversión alimenticia y eficiencia proteica. Además, se determinó el contenido de vitamina E, selenio, nitrógeno de bases volátiles totales y el estado de oxidación en el filete congelado. Los datos se ...

Mixed norms that promote structured sparsity have numerous applications in signal processing and machine learning problems. In this work, we present a new algorithm, based on a Newton root search technique, for computing the projection onto the l ?,1 ball, which has found application in cognitive neuroscience and classification tasks. Numerical simulations show that our proposed method is between 8 and 10 times faster on average, and up to 20 times faster for very sparse solutions, than the previous state of the art. Tests on real functional magnetic resonance image data show that, for some data distributions, our algorithm can obtain speed improvements by a factor of between 10 and 100, depending on the implementation. © 2019 Society for Industrial and Applied Mathematics.

The research “socioeconomic process and setting of territory evaluation in the province of Picota, Department of San Martín. 2012” has been executed with the purpose of evaluating the socioeconomic processes and of identifying the reasons that motivated the use and occupation of the territory. At the same time the purpose is to determine the zones of the current use generated by the anthropic activities processes and conditions that allowed to elaborate a database from field exists to ten districts of the Provinceswith the geographical application of information systems. For the visual analysis, one used the satellite images Landsat TM-5-2005, 2007 and 2099, likewise one used other sources of primary information for the identification and evaluation of activities. The reasons of the use and territory occupation identified are: Alternative cult...

Background: Different antigens are needed to characterize Plasmodium falciparum infection in terms of seroreactivity and targets for invasion inhibition, in order to guide and identify the proper use of such proteins as tools for the development of serological markers and/or as vaccine candidates. Methods: IgG responses in 84 serum samples from individuals with P. falciparum infection [classified as symptomatic (Sym) or asymptomatic (Asym)], or acute Plasmodium vivax infection, from the Peruvian Amazon region, were evaluated by enzyme-linked immunosorbent assays specific for a baculovirus-produced recombinant protein P. falciparum Merozoite Surface Protein 10 (rMSP10) and for non-EGF region selected peptides of PfMSP10 selected by a bioinformatics tool (PfMSP10-1, PfMSP10-2 and PfMSP10-3). Monoclonal antibodies against the selected peptides were evaluated by western blotting, confocal mi...

The measurement of recent malaria exposure can support malaria control efforts. This study evaluated serological responses to an in-house Plasmodium vivax Merozoite Surface Protein 8 (PvMSP8) expressed in a Baculovirus system as sero-marker of recent exposure to P. vivax (Pv) in the Peruvian Amazon. In a first evaluation, IgGs against PvMSP8 and PvMSP10 proteins were measured by Luminex in a cohort of 422 Amazonian individuals with known history of Pv exposure (monthly data of infection status by qPCR and/or microscopy over five months). Both serological responses were able to discriminate between exposed and non-exposed individuals in a good manner, with slightly higher performance of anti-PvMSP10 IgGs (area under the curve AUC = 0.78 [95% CI = 0.72–0.83]) than anti-PvMSP8 IgGs (AUC = 0.72 [95% CI = 0.67–0.78]) (p = 0.01). In a second evaluation, the analysis by ELISA of 1251 plasma...
