The teaching posture is a significant variable in the processes developed in a didactic session, being contemplated as an object of studies in a teaching methodology born at the Federal University of Ceará and which presents solutions to problems related to the way knowledge is formed by the student from of the teacher's actions. In this article, as part of the results of the thesis work, we discuss the origin and theoretical development of this scientific method applied to the classroom and it's influence and transformation in the production of knowledge for the teacher's work.

World tobacco production has stagnated periodically, ranging from 6 to 6.5 million tonnes in the last five years. The Balkan countries, including Macedonia, along with Greece, Bulgaria and Turkey, are the largest producers and exporters of quality oriental tobacco in the region. Tobacco production in the EU is based on certain EU regulations conceptualized as the Common Agricultural Policy (CAP). From 2007 to today, there have been major changes in EU policy on tobacco production, leading to a sharp decline in production in all member states, and especially in neighboring Greece.

Installation of ground wires is the basic method for protection of an OHL against lightning. Back-flashovers are the most frequent kind of trip outs in the case when an OHL is equipped with ground wires. At medium voltage OHL with high tower footing impedance almost every lightning strike to the line causes a trip out. The secondary effect of the lightning stroke became the major concern due to strong magnetic field around the downward conductor connecting the lightning rod to the grounding system.

The aim of this study is to find out the effect of different intensities of aerobic exercises on selected physiological variables among diabetic patients. Randomly selected 60 (N=60) diabetic patients whose blood glucose levels were more than 140 mmHg and who were undergoing treatment for diabetics in Government General Hospital, Nagercoil were treated as subjects for this study. They were randomly assigned into four groups consisting of 15 in each group.

Avaliaram-seas propriedades mecânicas de duas misturas asfálticas, uma confeccionada com vidro pulverizado no moinho de alta energia (CA-VID), e a outra composição com o fíler tradicional (CA-REF), visando suaaplicação em camadas de pavimento. Determinou-se a resistência à tração por compressão diametral (RT) e o módulo deresiliência (MR).

A gestão ambiental no setor madeireiro se caracteriza por práticas sustentáveis no sentido de reduzir e controlar os impactos ambientais causados pelas indústrias desse setor, sobretudo em relação ao gerenciamento e descarte ambientalmente adequado dos seus resíduos. Esta pesquisa teve como objetivo analisar a gestão ambiental como fator de minimização dos impactos ambientais em empresas do setor madeireiro do município de Cacoal/RO. Para tanto, realizou-se a pesquisa em 2 (duas) empresas do setor madeireiro do município.

This work presents an empirical methodology for comprehensive measurement of innovation in companies with a database bias. The structure focuses on what is necessary to obtain a competitive advantage and the factors considered important for a company to remain active, which were found on extensive literature. This developed structure identifies, through scoring, the degree of innovation of a company, showing a correlation between data processing and the degree of innovation on the companies.

Contemporary, Ethiopia is razed with various civil resistance, street blocked and small scale conflicts, all in all chaos form every corners of the country. Some of the conflicts are due to the recent national political reform introduced by the current Ethiopian prime minister, as it is seen in the case of Somali and Oromiaregional States. Others are due to path-dependent questions for equitable economic benefit, the demand for state infrastructure and actual state somatic presence.

Neste trabalho prova-se a viabilidade econômica da transformação e da reciclagem de resíduos de demolição de concreto, em comparação à aquisição de agregados convencionais. Grande parte dos resíduos de construção e demolição são agregados de classe A e tem seu descarte em não-conformidade com a Resolução no. 307, de 5 de julho de 2002 do Conselho Nacional do Meio Ambiente - CONAMA. Assim, os resíduos de construção e demolição são misturados e encaminhados junto com os agregados residuais, em forma de entulho, para o aterro sanitário de Manaus.

Diversos fatores impactam no aumento das doenças crônicas não transmissíveis (DCNT) e, consequentemente, na mortalidade mundial. Devido a isso, os pacientes acometidos por tais doenças fazem uso de diversos medicamentos de elevado custo que são disponibilizados pelo componente especializado da assistência farmacêutica (CEAF) de forma segura e eficaz. O objetivo desse estudo foi traçar um perfil farmacoterapêutico de usuários cadastrados em CEAF em uma cidade no interior do Nordeste/Brasil.
