The role of gallery forests in maintaining Phlebotominae populations: potential Leishmania spp. vectors in the Brazilian savanna.

Background: Knowledge on synanthropic phlebotomines and their natural infection by Leishmania is necessary for the identification of potential areas for leishmaniasis occurrence.

Objective: To analyse the occurrence of Phlebotominae in gallery forests and household units (HUs) in the city of Palmas and to determine the rate of natural infection by trypanosomatids.

Methods: Gallery forests and adjacent household areas were sampled on July (dry season) and November (rainy season) in 2014.

A literature review about usability evaluation methods for e-learning platforms.

The usability analysis of information systems has been the target of several research studies over the past thirty years. These studies have highlighted a great diversity of points of view, including researchers from different scientific areas such as Ergonomics, Computer Science, Design and Education. Within the domain of information ergonomics, the study of tools and methods used for usability evaluation dedicated to E-learning presents evidence that there is a continuous and dynamic evolution of E-learning systems, in many different contexts -academics and corporative.

A children, teachers and designers as evaluators of usability of educational software.

This article sets out to discuss the results of evaluations of usability made by children, teachers and designers through methods targeted on their profiles and contexts of use. Based on a survey of methods for evaluating usability, a field study was conducted in which such users--stakeholders--explored the educational software called "Mundo da Criança" ("Child's World"). The focus of this study was the analysis of this system and principally of the appropriateness of methods as to the avenues they suggest such users and contexts might explore.

RBCS1 expression in coffee: Coffea orthologs, Coffea arabica homeologs, and expression variability between genotypes and under drought stress.

Background: In higher plants, the inhibition of photosynthetic capacity under drought is attributable to stomatal and non-stomatal (i.e., photochemical and biochemical) effects.
