Several destinations can be given as the final disposal of municipal solid waste, however the most appropriate is the one carried out in landfills. However, municipal solid waste is not always receiving an adequate form of final destination, being discarded in dumps, which are old and recurrent practices in Brazilian municipalities, which is based on the dumping of waste in inappropriate places and without any treatment, which has caused environmental, economic, social and public health impacts.

Importance of the forest sector in the potential of attracting people. In this work, a modification of Newton's gravitational model was performed to determine the attraction potential of people in cities. It was proposed to add weights, defined by variables that make up the agricultural sector, which allowed us to identify the importance of each sector segment. Through the proposed modeling, it was identified that the Nominal Value of Forest Production presented the greatest potential for attracting people in the municipalities of the Second Parana plateau region.

This article aimed to analyze the precipitations and flows of the Manacapuru Hydrographic Basin and possible hydrological impacts caused by the el Niňo and La Niňa climatic phenomena on it, with the objective of providing subsidies for the formulation of public policies for the management of water resources and policies that favor the development of the sustainable economic activities of the municipality.

Urban solid waste management (RSU) is one of the biggest challenges in city management, while demand for electricity increases worldwide. Economically viable, socially fair and environmentally balanced solutions to such challenges need to be sought. Waste can no longer be seen as rejecting and being seen as an energy resource. The generation of energy through landfill waste is an alternative to the installation of new plants for energy production, can reduce the emission of greenhouse gases and also generate new jobs in the process.

The article discusses the common errors, the misconceptions and the problems related to the topic of comparing fractions and methods of teaching them. The following research is based on the qualitative approach which aims at examining the existing problems and ways of addressing them. The researcher discovered the significance of the conceptual instruction of the concept itself and the usage of the research methods, while avoiding indoctrinating the subject and using the ritual approach.

This paper examines the technical efficiency of smallholder wheat producers in three districts of the Misrak Gojam zone of Amhara region, Ethiopia. Using two stage stratified simple random sampling design, 210 wheat producing households were randomly selected and studied. Cobb-Douglas Stochastic Frontier Model was fitted to estimate farm level technical efficiency and the associated efficiency scores. The analysis of technical efficiency determents was conducted employing both Maximum likelihood (ML) and quantile regression techniques (QR).

Brazil has the largest blackpopulation outside Africa and the second largest in the world, surpassed only by Nigeria. More than 40% of the Brazilian population corresponds to Afro-descendants. Genotyping of the CYP2D6 gene may serve as a predictive tool for the pharmacological effectiveness and / or toxicity of various drugs. However, due to the high cost of genetic testing, it is necessary to know the population frequencies in order to facilitate the development of clinical and laboratory strategies.

The objective is to elaborate a food product developed from Pacu carcass subjected to different processing techniques that may contain healthy components and that is environmentally correct. Fish stocks were developed from three different products, here named as in natura carcass, smoked carcass, and carcass residual biomass. The chemical composition, colorimetric and microbiological profiles, and sensory analysis were evaluated in these stocks. The sensory analysis was based on the evaluation of 66 trained tasters concerning sensory attributes and consumers’ acceptance.

Coriander and arugula are fast-growing, short-cycle herbaceous leafy vegetables. Organic fertilizers increase plant yields by providing nutrients, improving soil physical and biological properties.The objective of this work was to carry out a practical experience of agroecology at Dom José Tupinambá da Frota State College, Sobral, Ceará, Brazil. The study was conducted in a garden in the courtyard of the College. Coriander cultivation was carried out from August 24 to September 19, 2018, in three beds prepared with manual hoe. The total area of each flowerbed (5 m x 0.8 m) is 4 m2.

Increased morbimortality related to non-transmissible diseases and pharmacotherapy required a new attitude of the pharmacist and greater involvement in the prevention of negative clinical outcomes associated with the use (or non-use) medicines. For patients with chronic diseases such as multiple sclerosis (MS), the influence of treatment on quality of life (QOL) is acrucial determinant during therapy. The aim of the study was to identify the impact of NRM on QL of MS patients. Method: Cross-sectional, descriptive and analytical study of MS patients.
