Potential of vermicomposting with mixtures of animal manure and vegetable leaves in the development of Eisenia foetida, microbial biomass, and enzymatic activity under semi-arid conditions.

Vermicomposting is the bio-oxidation and stabilization of organic matter involving relationships between the action of earthworms and microorganisms and the activation and dynamics of several enzyme activities. Semi-arid farmers to make (extra) money and organic production, produce their vermicompost using plant residues and animal manure, but there is no information about the final product generated. Thus, this study aimed to analyze the potential of vermicomposting with mixtures of animal manure and vegetable leaves in the development of Eisenia foetida, microbial biomass, and enzymatic activity in the semi-arid region, Brazil.

Prevalence of dyslipidemia in children from 2 to 9 years old.

Objective: Analyze the occurrence of dyslipidaemia and associated factors in children aged 2 to 9 years.

Method: Cross-sectional study, carried out with 700 children, in a region of Northeast Brazil. For comparison of means, Student's t test was used; and, for the comparison of medians, the Mann-Whitney test.

Temporal decomposition sampling and chemical characterization of eucalyptus harvest residues using NIR spectroscopy and chemometric methods.

Near-infrared (NIR) spectroscopy and chemometric methods were used to predict the chemical properties of decomposing eucalyptus harvest residues to better understand the decomposition process of these materials. Leaves, twigs, branches, and bark from a decomposition experimental set up in commercial plantations were sampled for one year. The contents of carbon (C), nitrogen (N), extractives (EX), acid-soluble lignin (SL), Klason insoluble lignin (KL) and holocellulose (HC) were determined by the reference method in the collected samples.

Training and knowledge of professionals of the health family team on reporting mistreatment of children and adolescents.

Objective: To analyze training and knowledge of professionals in the Family Health Team on reporting the mistreatment of children and adolescents.

Methods: Cross-sectional study carried out in three municipalities of Ceará State, Northeast Brazil, from January to April 2012. The research included 51 professionals: physicians (9), nurses (26), and dentists (16) who worked in the Family Health Strategy.
