Espaço, tempo e contradições: do Banco Nacional de Habitação ao Programa Minha Casa, Minha Vida em Presidente Prudente/SP

The housing issue in Brazil is'nt a recent problem and has been discussed, worked and questioned in the institutional framework, especially with regard to the critical considerations on the topic and urban problems involved. We as milestones in the Brazilian housing policy the National Housing Bank - BNH, 1964, the height of the military regime in Brazil, and the Minha Casa, Minha Vida, in 2009. Both have questions that approach and distance themselves regarding changes in the Brazilian housing policy, where we have the emergence of new forms of knowledge production and housing consumption. Thus we have a number of advances in ways of acquiring social housing, even at different times, it is characterized as capitalist forms of this issue. Thus the spatial process of housing developments arising from these programs reflect the change in space - time that they lay down, turning the urban space of the cities in this case the city of Presidente Prudente / SP

A questão do voto para o adulto analfabeto ou pouco letrado

The Youth and Adult Education is a reality that still stands on the school benches of Brazil. Elderly people historically get more integration in the world when appropriate to the written code. One of the issues that touch this insertion is the right to vote and, more than that, the awareness of the vote of young and adult illiterate or poorly literate. Thus, this project aims to raise throug the point of view of this student how he see himself as voter and what is their role in the democratic consolidation of this act, even if he is in the condition of illiterate or poorly literate. Therefore, a qualitative approach to research will be conducted, in which individual audio recorded interviews will be held, later transcribed and the data will be analyzed in the light of the studied literature, based on the writings of Paulo Freire. Will participate as subjects Teachers of EJA and of study the students enrolled in the Education of Young Adults rooms on the city of Bauru. The results shown in interviews with the teachers confirmed the investigation of expectations in the study of Paulo Freire which has literacy training as part of the citizenship, the results allowed the construction of the profile of a group of students. We also concluded that it was possible to deconstruct the myth of non-political consciousness of the illiterate and the presence of dialogue in pedagogical practice enabling awareness of Educating

Estudo da utilização de ferramentas a base de nitreto de silício (Si3N4) e alumina (Al2O3) na usinagem do ferro fundido vermicular

Machining is one of the most commonly manufacturing processes used in the modern world, consuming millions of dollars annually. Because of this, it is crucial for the automotive industry to reduce costs on their heat-resistant alloy machining processes, such as compacted graphite iron (CGI), which has shown an increasing trend of its application in diesel engine blocks, brakes disks, among other applications, due to its superior mechanical properties to gray cast iron. Despite this advantage, its use is still limited due to its difficulty of machining, moreover, cutting tools are displayed as the main factor in increasing the machining cost. Seeking an alternative to a better machinability of CGI, this paper aims to study two types of ceramic tools developed in Brazil, and benchmark their performance by dry turning. For this, were used CGI class 450 and two tools: ceramic of silicon nitride (Si3N4) and alumina-based (Al2O3), with a cutting speed (Vc) of 300, 400 and 500 m / min; feed (f) of 0.2 mm / rev and depth of cut (ap) of 0.5 mm, using three replicates and starting with new cutting edges. The results showed that the Al2O3 tool had the best performance in Vc of 500 m / min, while the Si3N4 tool had the best results in Vc of 300 m / min. This can be explained by the tool of Si3N4 based include soft intergranular phase, called amorphous, while alumina has higher abrasion resistance due to its high refractoriness. The results make it clear that the tools have significant potential for machining of compacted graphite iron, being necessary a strict control of the cutting parameters used

A importância da mediação: a situação do professor mediador escolar e comunitário na Rede Estadual Paulista de Ensino

This study aims to analyze the implementation of mediation in the school environment of São Paulo State Education Network through the figure of Teacher School and Community Mediator (PMEC). Mediation arises, as an alternative and effective method for conflict resolution from existing interpersonal relationships at school. The methodology used was the exploratory and empirical research literature on the subject mediation and the analysis of the resolutions of the Secretariat of São Paulo State Education establishing the School Protection System (SPE) and made possible the performance of the PMEC within that environment. Authors like Bonafé-Schmitt (2010); Caetano, Freire and Ferreira (2009); Calcaterra (2002); Freire (2010); Jares (2002); Lederach (1996); Littlejohn and Domenici (1999); Morgado and Oliveira (2009); Torremorell (2008) and Vecchi and Greco (1999) were selected in order to provide greater familiarity with the subject mediation and conflict mediation later in the school environment. The concept of mediation, mediation templates and profiles of mediators will be explained as well as PMEC function features as regards the selection methods training main assisted cases, assignments that are stipulated by the guiding documents and what actually happens in daily practice verified the reports obtained through a semi-structured interview. Finally, we present the PMEC situation regarding the review by the leaders and attended school community and the acceptance of their work within that environment

Resíduos de antibióticos e antiparasitários em alimentos de origem animal

O Brasil é considerado um grande produtor e consumidor de carnes, leite e alimentos de origem animal e os medicamentos veterinários têm sido amplamente utilizados na criação dos animais destinados ao consumo humano, com o intuito de prevenir o aparecimento de doenças e também como promotores de crescimento. Os fármacos utilizados para esta finalidade, no entanto, podem ocorrer nos alimentos derivados desses animais tratados, com conseqüências sobre a saúde humana. Além das substâncias utilizadas intencionalmente, a contaminação ambiental ou a presença de contaminantes em rações constitui uma fonte potencial de compostos cuja concentração no alimento final processado pode exceder os limites de segurança estabelecidos para garantir a saúde humana. Com o intuito de promover maior segurança alimentar, no Brasil, foram estabelecidos os programas PNCRC e o PAMVet, que são responsáveis pelo monitoramento da presença de substâncias ilegais (como os antimicrobianos nitrofuranos) e também, visam o controle do Limite Máximo de Resíduos (LMR). O objetivo do presente trabalho é reunir e discutir as informações sobre os principais resíduos e contaminantes de medicamentos veterinários em alimentos de origem animal no Brasil, assim como as publicações referentes às avaliações mais recentes desses produtos alimentícios presentes no mercado brasileiro. Estas informações serão utilizadas para novas discussões relacionadas ao uso adequado de medicamentos veterinários e à proposição de estudos de farmacocinética que poderão fundamentar o estabelecimento do período de carência para esses produtos farmacêuticos.

Utilização de métodos não invasivos para avaliação da segurança de fitocosmético contendo extrato de goiaba para aplicação tópica

É bem conhecido que uma das consequências causada pela radiação ultravioleta gerada pela luz solar é o fotoenvelhecimento e o desenvolvimento de cânceres cutâneos por meio da ação dos radicais livres gerados sobre a pele. A utilização de uma formulação de uso tópico pela população que auxilie na prevenção do envelhecimento precoce e de doenças causadas pelos radicais livres à pele humana seria de grande valia, trazendo benefícios estéticos, que influenciariam diretamente a saúde psicológica do usuário e preveniriam a fotocarcinogênese. Este fato se torna ainda mais importante em um país tropical como o Brasil, onde a incidência de radiação UV é bastante elevada, assim como o desenvolvimento de cânceres de pele na população. Devido às evidências encontradas em estudos prévios que indicam o potencial antioxidante da goiaba, esta pesquisa teve por objetivo desenvolver estudos para avaliação da segurança in vitro e in vivo de fitocosmético antioxidante através da avaliação do potencial mutagênico em cepas de Salmonella typhimurium, além de avaliar seu potencial irritativo e alergênico na pele de voluntários saudáveis. Para isto foi utilizado o método de Ames, amplamente utilizado para esta finalidade, em que o extrato de Psidium guajava L. foi considerado não mutagênico para todas as cepas avaliadas e foi possível constatar que o extrato promoveu efeito antimutagênico moderado apenas na cepa TA 100. No ensaio para avaliação do potencial irritativo e alergênico realizado in vivo, foi comprovada a ausência de potencial irritante e alergênico de fitocosmético. Desta forma, os estudos realizados indicam a segurança em utilizar o extrato de Psidium guajava L. como antioxidante de uso tópico.

Compostos bioativos dos alimentos e atenção farmacêutica: uma revisão de literatura no quadro da osteoartrite

O Brasil tem passado por uma revolução demográfica importante e, com o crescente número de adultos e idosos, há também o aumento do aparecimento de doenças crônicas não transmissíveis relacionadas ao envelhecimento. Um exemplo é a osteoartrite, uma doença degenerativa, que acomete diferentes articulações do corpo e atinge com mais frequência a população acima de 50 anos de idade. O tratamento farmacológico da doença visa aliviar os sintomas de dor e inflamação com a administração de anti-inflamatórios e analgésicos que apresentam muitos efeitos adversos. Como alternativa para auxiliar o tratamento da osteoartrite, podem ser utilizados compostos bioativos dos alimentos, também chamados nutracêuticos. É reconhecido cientificamente que alguns compostos bioativos presentes nos alimentos possuem, além de sua capacidade nutricional, um papel importante para a prevenção e tratamento de alguns estados clínicos. Este estudo busca analisar, por meio de uma revisão bibliográfica, os benefícios de quatro nutracêuticos, quando utilizados no tratamento da osteoartrite. Dentre os nutracêuticos pesquisados, estão o ácido ascórbico, os insaponificáveis de abacate e soja, a vitamina D e o ômega 3, que auxiliam no tratamento do quadro inflamatório e na reparação da cartilagem danificada. Uma nova perspectiva no auxílio do tratamento da osteoartrite impõe ao farmacêutico adquirir um conhecimento interdisciplinar que possa contribuir para a orientação e informação de pacientes no exercício da atenção farmacêutica, a fim de sanar possíveis dúvidas dos pacientes sobre tais compostos e melhorar o aproveitamento do tratamento na melhoria de sua qualidade de vida.

Utilização de trocadores de calor de placas em espiral em processos da indústria siderúrgica

Stricter environmental policies are shown necessary to ensure an effective pollutant emission control. It is expected for the present year of 2015, that Brazil will assume, at the 21th United Nation's Climate Change Conference (COP21), implementation of commitment to a low carbon economy. This positioning affects the industrial environment, so that is deemed necessary to search for new technologies, less aggressive to the environment, so the adequacies to the new emission policies do not cause a negative effect on production. Almost all of the processes performed in the steel industry demand burning fuel and, therefore, flue gases are sent to the atmosphere. In this present work is discussed the utilization of heat exchangers so, by recovering part of the available heat from the flue gases of certain industrial process, the combustion air is preheated. The combustion air preheat results in less energy requirement, i.e., less need of fuel consumption and, in addition, minor amount of pollutants to be emitted. Due to better fitting to the process, it is studied the utilization of spiral plate heat exchangers. The heat exchanger dimensioning is made by an iterative method implemented in the software Microsoft Excel. Subsequently are analyzed the gains in terms of process's thermal efficiency improvement and the percentage of fuel saving. The latter implies in reduction of the same percentage of greenhouse gases emission

Obtenção e caracterização de nanocelulose a partir de fibras de Chorisia speciosa St. Hil

Natural fibers have been highlighted as a renewable material that can replace materials from oil and its derivatives. In this context, Brazil becomes the perfect setting because of the diversity of fibers found in its territory, such as sugarcane, sisal, rice, cotton, coconut, pineapple, among others. The paineiras (Chorisia speciosa St. Hil) are typically Brazilian trees, which produce paina as fruit. These fruits are still little studied as a source of lignocellulose by research groups. This project aimed obtaining and characterization of cellulose nanofibers from the fibers from the paina fibers. Obtaining nanocellulose is practically made through simplified chemical processes. First, was performed out pre-treatments to removal of waxes, lignin and hemicellulose. The first stage of pre-treatment was carried out by alkaline aqueous solution of sodium hydroxide (NaOH) at 5wt%, where the fibers were under constant agitation for 1h at 70°C. Through alkali treatment it was possible to remove most of the lignin, hemicellulose, waxes and extractives. After the alkaline treatment was done bleaching with an aqueous solution of sodium hydroxide (NaOH) to 4wt% and hydrogen peroxide (H2O2) to 24wt% 1:1 during 2h with constant stirring to 50 °C. Through bleaching was possibe to remove residual lignin, and got cellulose with 72% of crystallinity. Nanocellulose of paina fibers was extracted using different conditions of acid hydrolysis with sulfuric acid (H2SO4) to 50wt%. After acid hydrolysis, the suspensions were centrifuged during 30 min and dialyzed in water to remove excess acid until neutral pH (6-7). Then the suspensions were passed by ultrasonification in an ultrasound 20 kHz during 1h in an ice bath. Untreated, alkalinized and bleached fibers as well as cellulose nanoparticles were characterized by the techniques of thermogravimetry ... (Complete abastract click electronic access below)

Estudo da viabilidade da implantação de frotas de veículos elétricos e híbridos elétricos no atual cenário econômico, político, energético e ambiental brasileiro

Currently there are two car models that use electricity in their propulsion systems, the electric vehicle and the hybrid electric vehicle. The electric vehicles are classified as vehicles that use electric motors in their propulsion system and batteries as a power source, on the other hand, the hybrid vehicles are classified as vehicles that use both electric motors and internal combustion engines in their propulsion system, using both batteries and líquid fuels as a power source. The main goal of this work is to analyze the characteristics of electric and hybrid electric vehicles and demonstrate the unfeasibility of the electric vehicle in the current economic, political, energetic and environmental brazilian scenario, for this purpose it was realized a study about the current brazilian situation regarding to electricity generation, current conservation status of road network, lack of electrical infrastructure for charging batteries, national lithium reserves, environmental characteristics, tax incentives, economic scenario, oil market and political positioning related to the implantation of electric or hybrid electric fleets in nacional territory. The operational characteristics analysis of electric and hybrid electric vehicles in this current scenario leads to the conclusion that currently a growth of electric vehicles fleets on a national scale is totally impractical in the Brazil, Thus, the introduction of green vehicles probably will occur primarily with hybrid electric models, motivated mainly due the bigger autonomy of this models compared to electric models, lower cost of hybrid electric models compared to electric models, factors related to the lack of recharging infrastructure and also factors related to political positioning
