Amostragem de poluentes particulados emitidos pela queima de biomassa em correntes confinadas

It is clear today the ever-accelerating search for new fuels that will eventually replace those that will survive in our society, which are fossil fuels. For this reason, a fuel used since the dawn of humanity and much studied since then, considered the generator of clean, renewable energy, can earn more and more space in the power generation sector, which is biomass. We performed two experiments with two different types of biomass, one from the Amazon rainforest and other pine and eucalyptus as waste from the sawmill UNESP Itapeva. In the first experiment, conducted at the Laboratory of Combustion and Propulsion INPE Cachoeira Paulista were conducted three tests in a chimney with a fan creating forced ventilation, where the biomass was burned and deposited on a support beneath the hood. In the second experiment was conducted to analyze the emission of particulate matter using biomass (waste) from the sawmill on the campus of UNESP experimental Itapeva the burning of it in a burner for heating water for a wood oven. In these experiments we used a particle called DATARAM4 sampler that is capable of sampling both outdoors and inside of pipelines, which is the focus of this work. With this equipment it was possible to measure the concentration of particulate matter in all the firings as above, and compare them to levels acceptable in the current law, always trying to analyze the so-called fine particles, which are those with diameters less than 2.5 μm. Using data obtained from the equipment was also possible to evaluate the diametral distribution of particulate matter in question, and verify which phases of the flares in the concentration and the diameters of the particles are the most critical. In this work we concluded that in all firings conducted concentrations of particulate matter were higher than that allowed by the law, and the diameters were found that are more harmful to human health

Expectativas de pais, professores e crianças acerca da escolarização no contexto das camadas populares

In regards to the context of the schooling for less the most favored, the school did not appear as intellectual instrument, and yes as prerequisite to take care of to the new requirements of the work market that if modernized the great social changes together with. The school, in turn, if puts in charge them to know scientific, and, for times, them norms of effective behavior in the society and the familiar group, them feelings and moral values, in a transposition of the “cultural capital” and it “capital stock” that passed by generations. This work, therefore, had as objective to study the expectations of schooling of the child in pertaining to school age, in the universes of the family and the school, from the speech of the agents of this process (parents, responsible, professors and the children) and of some practical educative referring to the schooling of the child, leaving of estimated of that the school is a democratic space, with equality of rights and the duties. Mediated for cultural a historical boarding, one searched to interpret the pertaining to school and familiar context of the participants, by means of a counterpoint with the studied bibliography, being this presented throughout the work. The research was of qualitative character, the data had been collected by means of comment in two classrooms, one of the third and one of the room year. Half-structuralized interviews had been made, that had been recorded e, later, transcribing. The environment of the research was a public school of the basic education of a city of the interior of the State of São Paulo, that received children proceeding from families of the urban popular classrooms. The results of the analysis of the data point that the professors present a vision of ideal model of family and pupil that does not correspond to the reality of the context of these and of the new nomenclatures of the familiar order...

Estudo da influência das resinas termofixas uréia formaldeído (UF) e melamina formaldeído (MF) nas características físicas e mecânicas de painéis MDF

Thermosetting resins are very important in the production of MDF panels. They act as an adhesive in the process of compacting and consolidating the fiberboard. Thermoset resins commonly used in this process are based resin urea formaldehyde (UF) and melamine formaldehyde (MF). The first has a higher demand due to its low cost and good performance in meeting the specifications and standards. The second has a high cost compared to MF resin, but adds greater value to the MDF panel, because it gives greater moisture resistance. The process of manufacture of MDF boards was briefly presented in this study to facilitate the understanding of the work. Samples of thermosetting resins (UF and MF) were subjected to physical-chemical seeking to relate these results to the technological performance presented by their respective samples of MDF boards. Two other samples of MDF panels were subjected to physical and mechanical tests. Results were analyzed and related to the award of their respective thermoset resin. Instruments like Dahmos Trend Manager ® and Grecon Dax 5000 and TG - DSC analysis were used in this study to assist in the analysis of the results. It was observed that the results of the analysis of thermosetting resins were within the specified. Such resins do not directly influence the technological tests provided by the MDF panels, but it has been found that the process variables such as humidity and fiber production rate interfere with the performance of the resin accelerating the reaction and therefore their influence on the physical-mechanical properties of the panels MDF. Samples of MDF panels with UF and MF met all the specifications required by the Brazilian standard with regard to the technological quality. The increased demand for UF resin market is justified by the service specifications...

Diga-me quem tu és: o léxico-marketing na publicidade e o comportamento de gêneros sociais

It is unanimous among lexicologists that lexical units present deep marks in the representativeness of cultural and behavioral issues. Thus, some scholars have been proposing methodologies in order to enable the verification, scientifically, of mechanisms to systematize the lexicon within a specific time/space. In this way, it would be possible to promote discussions about its relations with social matters. These lexical contents can be analyzed, for instance, in the publicity having in mind its power of extending the desires of its receiver/customer to the acquisition of products/services since it is a media outlet that provide aids, by means of verbal texts produced by advertising editors, in order to deal with issues of our society, as those related to female and male genders. From all of this, the present article aims at organizing lexical items in market segments, here referred to lexicon-marketing, so as to make possible observation of social behaviors in the universes of both women and men.

Disparos: ensaios sobre fotografia de guerra

Once the choices set involved in the selection of compositional techniques of a photography is mediated by ideological universes, this final project aims to analyze the photographic coverage of the World War II presented in the brazilian publication Revista da Semana during the period in which Brazil was part of the conflict (1942 to 1945). We study the different composition techniques used and the different effects of meaning articulated by these techniques. Thus, our goal is to see how the repetitions are articulated and the translations of meaning in photojournalistic composition from its narrative structure, that is, their way of coded organization. For this, we used the analysis methodology proposed by Umberto Eco on the rhetoric of the image, involving the five levels of photography decomposition (ie iconic levels, iconographic, tropological, topic and enthymematic). We will analyze these images from the perspective of the effects of meaning that the composition techniques to engender glimpse which were woven meanings to this event in that specific space, and which were mediated discourses of Brazilian participation in the conflict

Chitosan-alginate membranes accelerate wound healing

The purpose of this study was to evaluate the efficacy of chitosan-alginate membrane to accelerate wound healing in experimental cutaneous wounds. Two wounds were performed in Wistar rats by punching (1.5 cm diameter), treated with membranes moistened with saline solution (CAM group) or with saline only (SL group). After 2, 7, 14, and 21 days of surgery, five rats of each group were euthanized and reepithelialization was evaluated. The wounds/scars were harvested for histological, flow cytometry, neutrophil infiltrate, and hydroxyproline analysis. CAM group presented higher inflammatory cells recruitment as compared to SL group on 2nd day. On the 7th day, CAM group showed higher CD11b+ level and lower of neutrophils than SL group. The CAM group presented higher CD4+ cells influx than SL group on 2nd day, but it decreased during the follow up and became lower on 14th and 21st days. Higher fibroplasia was noticed on days 7 and 14 as well as higher collagenesis on 21st in the CAM group in comparison to SL group. CAM group showed faster reepithelialization on 7th day than SL group, although similar in other days. In conclusion, chitosan-alginate membrane modulated the inflammatory phase, stimulated fibroplasia and collagenesis, accelerating wound healing process in rats.
