This work was to evaluate the catalytic properties Ru/Cobalt/SBA-15 catalyst for Fischer-Tropsch synthesis (FTS). The molecular sieve SBA-15 synthesized by hydrothermal method with rice husk ashes (RHA) and with tetraethyl orthosilicate (TEOS). The Ru promoted Co/SBA-15 catalyst was prepared by wet impregnation method and was characterized by X-ray diffraction, X-ray energy dispersion spectrophotometer, N2 adsorption-desorption, temperature-programmed reduction and transmission electron microscopy.

Este artigo tem por objetivo afirmar a importância dos estudos de memória para compreensão dos processos sócio-históricos contemporâneos, a partir da inserção, da permanência e da ampliação da participação de negros no percurso do subcampo esportivo do handebol, no ginásio desportivo Ronald da Silva de Carvalho (corpus empírico) da antiga Escola Técnica Federal do Maranhão (ETFMA), entre 1970 e 1980.

The Caruru-de-espinho (Amaranthusspinosus) is an edible plant belonging to the genus Amaranthus, and family Amaranthaceae, having high nutritional content, in addition to being the target of phytochemical studies. In view of this, the objective is to evaluate the phytochemical, protein and nutritional content of the spiny caruru (Amaranthusspinosus) harvested in a city in Bico do Papagaio, North of Tocantins, Brazil. This is a descriptive, experimental study.

Introdução: A Síndrome de Guillain-Barré (SGB) é uma neuropatia, de caráter autoimune, responsável por diminuição dos reflexos profundos e fraqueza motora progressiva. Nesse sentido, objetiva-se analisar e coletar dados da SGB induzida pela bactéria Campylobacter. Métodos: É uma revisão integrativa qualitativa e retrospectiva. Utilizaram-se as bases de dados PubMed, MEDLINE, Scielo, UpToDate, BVS e LILACS. Os descritores foram “Síndrome de Guillain Barré”, “Campylobacter jejuni”, “Epidemiologia” e “Manifestações Clínicas”, baseados nos Descritores em Ciências da Saúde (DEcS).

La La structure des macroinvertébrés et l’état de santé biologique des réservoirs n°2 de Ouagadougou et de Ziga ont été examinésdans cette étude. Pour ce faire, lesvariables physico-chimiques clés ont été mesurées in-situet les macroinvertébrés collectésselon la méthode d’échantillonnage multi-habitat à l’aide d’un filet troubleau de juillet à septembre 2020. Au total, 31 familles de macroinvertébrés dominés par des Insectes, suivi des Crustacées, des Mollusques et des Annélides, ont été rencontrés.

A Internacional Association for the Study of Pain (IASP), Define a dor como uma condição de difícil compreensão, sendo multifatorial. Alem disso, classifica-se a dor como aguda, quando há a sua prevalência por até três meses e a dor crônica quando a sua prevalência é continua.

Purpose: To evaluate all lymphoproliferative lesions of the orbital and adnexa diagnosed at our hospital during 11 years. Methods: Observational, Retrospective descriptive análisis. For statistical analysis we used SPSS package. Results: 74 cases with lymphoproliferative lesions of the orbital and adnexa were identified. 45 Female and 29 Male, with median age of 60 years. Most common presenting symptoms were increase of volumen and proptosis. Pathologic and immunohistochemistry diagnosis coincided in 71.6 % of cases. All specimens represented B cell non-Hodgkin’s lymphomas.

The suitability of an analytical method determines the characteristic performance of a method when it evaluates parameters such as selectivity, accuracy, precision and robustness. Thus, this research aims at describing the suitability of an analytical chromatographic method to determine metoprolol tartrate content in a coated tablet. This method has been considered accurate and robust since its results were recorded according to the recommended acceptance criteria (98-102%).

La educación es un campo en constante evolución, y en los últimos años, la neurociencia ha proporcionado valiosos conocimientos sobre cómo funciona el cerebro y cómo aprendemos. La integración de la neurociencia y la didáctica ha abierto nuevas perspectivas para mejorar las estrategias de enseñanza y promover un aprendizaje más efectivo. En este resúmen, exploraremos la relación entre la neurociencia y la didáctica, y cómo su integración puede beneficiar a estudiantes y educadores. Material dado en el programa de post doctorado en estrategias didácticas para la investigación científica.
