Evaluation of the antimicrobial potential of actinomycetes isolated from mangrove soils in the municipality of São João de Pirabas, Pará, Brazil

The present work aimed to characterize mangrove-derived actinomycetes strains isolated from São João de Pirabas mangrove in Pará State of Brazil and evaluate their antimicrobial action against clinical importance bacteria. Sixteen isolated actinomycetes strains were evaluated by their morphology and biochemical features and antibacterial activity against Staphylococcus aureus, Escherichia coli, Klebsiella sp. and Enterococcus faecalis.

Nitretação de aço inoxidável martensítico (aisi 4120) por descarga luminosa

In the present work was investigated nanoscale tribo-mechanical properties of martensitic stainless steel (AISI 420) subjected to nitriding by glow discharge (DL). Martensitic steels have been previously heat-treated in 1025 °C with subsequent rapid cooling in oil. The samples have been nitrided using the following parameters of temperature (°C) – time (h): 350/6, 400/6 e 450/6. The treatments were held in atmospheres of N2/H2 in the proportions of 20%-80% (in volume).

Pandemic and covid-19: a mathematical analysis of the (un) predictability of cases in the state of amazon

The pandemic of COVID-19 began in May 2020, as declared worldwide by the World Health Organization (WHO), with approximately 589,680,368 cases and 6,436,519 deaths from the disease being confirmed by the year 2022. In Amazon, up to August 14, 2022, 14,249 Covid-19 deaths have been recorded, 342 this year alone. This is an epidemiological study of a quantitative nature, in the application of mathematical models for event prediction and management in health services.

Development of a cereal bar containing the plant pereskiaacuelata miller

The Pereskiaacuelata plant has high nutritional value in its leaves, being rich in proteins, vitamins and minerals. The present work had as objetive develop a cereal bar containing the Pereskiaacuelata plant. The leaves of P. aculeata were dried and crushed in a knife mill and then the powder obtained from the plant was used in the preparation of the cereal bar, along with oat bran, rice flakes, sucrose syrup and honey.

Análise temporal do uso e ocupação do solo na zona de amortecimento da reserva biológica do jaru, rondônia

As unidades de conservação têm como principal função a conservação da biodiversidade, atuando como barreira para conter a degradação ambiental, entretanto, para que as unidades possam ser totalmente protegidas, é necessário o controle das atividades realizadas no entorno, a fim de evitar que impactos negativos atinjam a unidade. Portanto, o objetivo do trabalho foi realizar análise temporal do uso e ocupação do solo na zona de amortecimento da Reserva Biológica do Jaru, Rondônia.

Tool for automated planning of medium voltage networks considering the expansion of photovoltaic distributed generation

This paper deals with the general status of the rural Indian women and the Awareness of women Policies in rural areas and impact of women Policies on rural women. Women Plays vital role in our Indian Society. Rural women play a key role in supporting their households and communities in achieving food and nutrition security, generating income, and improving rural livelihoods and overall well-being. They contribute to agriculture and rural enterprises and fuel local and global economies. In concern Government has taken so many Programmes and Policies for women empowerment.

Unsteady mhd free convective fluid flow embedded in a porous medium with heat source in the presence of soret and radiation effects

The present research paper aims to study the effect of soret and radiation effects on an MHD convective fluid flow embedded in a porous medium with heat source. Dimensional non-linear coupled differential equations transformed into dimensional less by introducing similarity variables Time-dependent suction is assumed and the radiative flux is described using the differential approximation for radiation. The Galerkin finet element method is used to solve the equations governing flow.

Os possíveis riscos ao desenvolvimento fetal provocado pelos medicamentos usados no tratamento emgestante com epilepsia- uma revisão

Introdução: A epilepsia é um termo que engloba múltiplas anormais do comportamento cerebral, que se repetem espontaneamente. Significa repetição de crises epilépticas, que não são provocadas. Este artigo buscar aprofundar o conhecimento com relação aos fármacos usados no tratamento das crises epilépticas, principalmente em gestantes com relação a possíveis complicações morfológicas e fisiológicas para o desenvolvimento do feto. Objetivo: Conhecer os possíveis riscos ao desenvolvimento fetal provocados pelos medicamentos usados no tratamento em gestante com epilepsia.

Projetos e programas de atividade física para idosos em universidades públicas brasileiras: um olhar a partir de seus coordenadores

O objetivo deste estudo foi investigar e descrever as percepções dos coordenadores dos programas de atividade física ofertados para idosos nas universidades públicas brasileiras de diferentes regiões, identificando semelhanças, diferenças e destacando indicadores para formulação de futuras propostas. Realizou uma pesquisa qualitativa, exploratória e descritiva. De um universo de 109 universidades públicas brasileiras, coletaram-se dados por meio de instrumento online com uma amostra de 54 coordenadores.

In what direction is humanity evolving?

The elements that make up some systems are competing with each other for resources. Following the path of ending this struggle, evolution strengthens the reliability of the existence of these systems. This is how the Metazoa and Metaphyta evolved. Therefore, they thrive on the Earth. The development of human societies is a special case of the evolution of systems that have improved the reliability of their existence by stopping the struggle between elements of which they consist. The engine of this struggle is atavistic instinct of selfishness.
