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.

The comments of scientists and managers of water resources management have recently emphasized that water is very precious to serve and develop socio-economic. Therefore, the use of Artificial Intelligence (AI) technology, especially Artificial Neural Network (ANN) to manage water resources and forecast the hydrological variables for river basins is essential.

Vehicle Routing Problem has been a classic optimization deadlock, which has been present in operational research for the last 50 years. It aims to find solutions to minimize distances to be covered in delivery demands. Over time and considering the development of logistics, some variants have emerged, such as Last Mile Delivery. These comprise the final stretch, from the regional distribution center to the end user.
