Biomass is a renewable energy source, its use has received great attention due to environmental considerations and the increased need for energy worldwide, is clean and emit low greenhouse gas emissions compared with fossil fuels. The bark of cashew nuts (CCC), waste from the processing of almonds, which is excessively generated in our state and has not been administered correctly, so it is wasting its full potential, i.e., the main source for generating energy from biomass is in the waste. However, the use of agro industrial wastes energy is obtained by performing the archaic form of direct burning in ovens and chairs. Through the biomass gasification, process which converts the waste gas with an energy properties. We studied the conditions for utilization of biomass in order to obtain the best thermochemical conversion of biomass (direct combustion, pyrolysis and gasification). Had the opportunity to know the full operation of the gasifier, the phases of operation (heating, drying, pyrolysis and gasification) and to influence and select the ideal operating conditions. Applying methods of thermodynamic analysis and energy found in the literature and using data collected from tests performed in the fluidized bed gasifier installed was possible to determine the efficiency and potential (energy available and dissipated) of the gasifier. © 2015 IEEE.

The genus Lippia (Verbenaceae) comprises about 200 species of pantropical distribution. Lippia gracilis Schauer, popularly known as the mountain balm, is an aromatic plant, native of northeastern Brazil, used in folk medicine as an antiseptic and to treat dermatitis. Although cytogenetic serve as a tool in taxonomy rate, cytogenetical studies of genus Lippia are restricted. Given the above, the present study aimed to determine, at the first time, the chromosome number of copies of L. gracilis, and thereby contribute to a better taxonomic understanding of this genus. In this sense root tips collected from newly planted specimens were pretreated with a solution of 2mM 8-hydroxyquinoline for 4 hours, fixed in Carnoy 3:1 (ethanol: acetic acid) for 24 hours and stored in the same fixative for later analysis. The roots were hydrolyzed in 5N HCl for 20 minutes and the slides, prepared by squashing in acetic acid (45%) and stained with 2% Giemsa. The best metaphases were photographed and pointed to the chromosome number 2n = 24. Moreover, were observed metacentric and submetacentric chromosomes. Because there are several chromosome numbers in the genus, from n=10 to n=30, and as the same is little known cytogenetically, f more comprehensive cytogenetic studies are necessary, involving a larger number of species, so these data may help to clarify taxonomic inconsistencies in the family Verbenaceae.

The aim of the present research was to perform a discreet choice preference analysis model and assess the oilseeds offer, through Stated Preference data, considering that the Brazilian Law 11.097/2005 establishes compulsory introduction of biodiesel in the Brazilian energy matrix, guaranteeing its demand. Descriptive survey methodology was used. The universe of this study comprised median and small national producers, adding up to a sample of 114 valid answered questionnaires. Quantitative model with Stated Preference Analysis of data treatment was used. Among the main results of this study, it was possible to verify that the most important attributes were economic return and existence of satisfactory national technical assistance. The variable extracted oil content is presented as unimportant to national producers' choice. A suggestion for further studies is the application of similar researches to other Brazilian cities and States. Source


The paper discusses the current challenges encountered in caring for children with mental health problem in the context of the Family Health Strategy (FHS). Therefore, this study sought to understand how the matrix support (MS) has been used as a tool for care of children with mental health problems in the Family Health Strategy. Interviews were conducted with professionals involved in the work of MS in mental health in the FHS and relatives of children seen by this form of mental health care. The narratives were analyzed by Paul Ricoeur's Hermeneutic- Phenomenology approach. When questioned about cases of child seen at matrix support, it was discussed, even with some controversy, almost no attention to this age group. Therefore, it was realized that not only the issue of child mental health is still poorly studied, but its population is not perceived in the context of the FHS. At the same time, the mother's difficulty in exposing the children's mental health problems in the context of the FHS has also inhibited the care for this population. Moreover, little training in child mental health of health workers has become an obstacle to the effectuation of care for children. Thus, these issues must be discussed and addressed effectively, so that, as recommended to adults, children with mental health problems can be cared for in a comprehensive way, being, however, observed differences in their development and needs.
