Este artigo tem como objetivo analisar a reestruturação da produção agrícola na organização do espaço agrário brasileiro. O encaminhamento metodológico utilizado na elaboração deste trabalho foi a pesquisa bibliográfica e busca de informações e dados junto ao Ministério da Integração Nacional referentes à Política Nacional de Desenvolvimento Regional. O espaço agrário brasileiro tem passado por constantes transformações espaciais decorrentes da territorialização do capital, à luz do agronegócio da commodity soja, assim como tem ocorrido implicações decorrentes da reestruturação produtiva conformando e consolidando regiões. Tal situação é resultante de um conjunto de ações de gestores públicos, agroindústrias, produtores e empresas que prestam serviços à cadeia produtiva do agronegócio para garantir a materialidade da produção, circulação e venda da commodity soja.

O presente trabalho tem como objetivo central analisar o cerrado a partir da sua localidade. Bioma, domínio morfoclimático, território, várias são as denominações recebidas pelo cerrado. Apesar de todas essas denominações existe uma questão central na qual influencia de modo decisivo na sua atual configuração regional: a localização. Claro que não é o único fator para entendermos a devastação contemporânea, mas é um importante aspecto. Partindo daquilo que Alan Bourdin (2009) nos coloca a partir da questão local, podemos compreender que a centralidade e proximidade dos lugares dinâmicos do país contribuíram para sua ocupação e conseqüentemente sua modernização. A expansão econômica brasileira se dá de acordo com sua ocupação e essa se inicia no litoral. Portanto, as áreas mais centrais do Brasil só serão incorporadas pela economia nacional no inicio do século XX. Para entendemos o processo de modernização e povoamento tendo como base a localidade do Cerrado iremos abordar alguns assuntos, tais como: O processo de povoamento a partir da políticas públicas engendras pelo Estado brasileiro, o contexto internacional de expansão da agricultura, as técnicas modernas e a globalização.

O texto tem por objetivo explicar o desenvolvimento territorial brasileiro, analisando a modernização industrial em áreas do sertão. O trabalho levanta hipóteses explicativas sobre a industrialização e o papel do Estado, enquanto mentor e executor dos planos econômicos,  refletindo sobre a sua importância   em determinar a  estrutura da economia espacial. A despeito da relevância desta discussão não há estudos específicos realizados sobre a temática no espaço delimitado para análise. Para responder as questões, realizou-se revisão de literatura, visando o aprofundamento do debate teórico-conceitual, em seguida fez-se o levantamento de dados demográficos do Instituto Brasileiro de Geografia e Estatística (IBGE). A pesquisa buscou subsídios sobre a formação territorial, e as informações referentes à modernização industrial foram  coletadas no Centro das Indústrias de Feira de Santana (CIFS). O estudo está alicerçado na abordagem crítica, permitindo a leitura sobre a totalidade da produção econômica do espaço territorial brasileiro/latino-americano. Conclui-se que a modernização industrial no sertão brasileiro produz um desenvolvimento territorial tendo por base a ampliação tecnológica.

The creation of the Brazilian Program for the Modernization of the Horticulture by the Secretariat of Agriculture and Supplying of the State of São Paulo at CEAGESP, determined the standardization of fruit and vegetables in the follow aspects: degree of coloration, format, calibers, defects and packing. Therefore, the main goal of this research is to correlate the classification given by the Brazilian Program with the one used by the wholesalers at CEAGESP, verifying if the established norms are being fulfilled for cultivar Carmen and Debora (SAKATA SEED). The results showed, that for cultivar Carmem, for the averages of the observed values it does not move away from the norms created by the Program for sizes small and medium. However, for the case of cultivar Debora, the results showed differences between the adopted classifications. The tomatoes were devaluated, because had been commercialized below of the standardization indicated for the Brazilian Program.

Quality evaluation of classification was done in two fresh market tomatoes packing house, using electronically and mechanical equipments in two harvest periods, summer and winter seasons. The main goal of this work was to evaluate size and color grading conformity with the standards proposed by the Brazilian Program for Horticulture Modernization and size grading obtainded with the one established by the packer. The cultivar studied was Carmen. The results showed that there was no grade conformity with the fresh tomato quality standards proposed by the Brazilian Program for Horticulture Modernization. The grade conformity obtained when compared with the one programmed by the packer, was only for large sizes, in both equipments. The electronically equipment has presented better performance, over the mechanical, considering grading quality and fruits post-harvest quality. However, the electronically equipment must be constantly monitored to achieve efficiency and investment return. On the other side, for mechanical equipment it will be necessary to review the actual system of size grading, in order to follow the fresh tomato quality standards.

OBJECTIVE: The aim of this study was to evaluate the capacity of potassium oxalate, fluoride gel and two kinds of propolis gel to reduce the hydraulic conductance of dentin, in vitro. MATERIAL AND METHODS: The methodology used for the measurement of hydraulic conductance of dentin in the present study was based on a model proposed in literature. Thirty-six 1-mm-thick dentin discs, obtained from extracted human third molars were divided into 4 groups (n=9). The groups corresponded to the following experimental materials: GI-10% propolis gel, pH 4.1; GII-30% propolis gel; GIII-3% potassium oxalate gel, pH 4,1; and GIV-1.23% fluoride gel, pH 4.1, applied to the dentin under the following surface conditions: after 37% phosphoric acid and before 6% citric acid application. The occluding capacity of the dentin tubules was evaluated using scanning electron microscopy (SEM) at ×500, ×1,000 and ×2,000 magnifications. Data were analyzed statistically by two-way ANOVA and Tukey's test at 5% significance level. RESULTS: Groups I, II, III, IV did not differ significantly from the others in any conditions by reducing in hydraulic conductance. The active agents reduced dentin permeability; however they produced the smallest reduction in hydraulic conductance when compared to the presence of smear layer (P<0.05). The effectiveness in reducing dentin permeability did not differ significantly from 10% or 30% propolis gels. SEM micrographs revealed that dentin tubules were partially occluded after treatment with propolis. CONCLUSIONS: Under the conditions of this study, the application of 10% and 30% propolis gels did not seem to reduce the hydraulic conductance of dentin in vitro, but it showed capacity of partially obliterating the dentin tubules. Propolis is used in the treatment of different oral problems without causing significant great collateral effects, and can be a good option in the treatment of patients with dentin sensitivity.

OBJECTIVE: The aim of the present study was to verify the torque precision of metallic brackets with MBT prescription using the canine brackets as the representative sample of six commercial brands. MATERIAL AND METHODS: Twenty maxillary and 20 mandibular canine brackets of one of the following commercial brands were selected: 3M Unitek, Abzil, American Orthodontics, TP Orthodontics, Morelli and Ortho Organizers. The torque angle, established by reference points and lines, was measured by an operator using an optical microscope coupled to a computer. The values were compared to those established by the MBT prescription. RESULTS: The results showed that for the maxillary canine brackets, only the Morelli torque (-3.33º) presented statistically significant difference from the proposed values (-7º). For the mandibular canines, American Orthodontics (-6.34º) and Ortho Organizers (-6.25º) presented statistically significant differences from the standards (-6º). Comparing the brands, Morelli presented statistically significant differences in comparison with all the other brands for maxillary canine brackets. For the mandibular canine brackets, there was no statistically significant difference between the brands. CONCLUSIONS: There are significant variations in torque values of some of the brackets assessed, which would clinically compromise the buccolingual positioning of the tooth at the end of orthodontic treatment.

Angle Class III malocclusion has been a challenge for researchers concerning diagnosis, prognosis and treatment. It has a prevalence of 5% in the Brazilian population, and may have a genetic or environmental etiology. This malocclusion can be classified as dentoalveolar, skeletal or functional, which will determine the prognosis. Considering these topics, the aim of this study was to describe and discuss a clinical case with functional Class III malocclusion treated by a two-stage approach (interceptive and corrective), with a long-term follow-up. In this case, the patient was treated with a chincup and an Eschler arch, used simultaneously during 14 months, followed by corrective orthodontics. It should be noticed that, in this case, initial diagnosis at the centric relation allowed visualizing the anterior teeth in an edge-to-edge relationship, thereby favoring the prognosis. After completion of the treatment, the patient was followed for a 10-year period, and stability was observed. The clinical treatment results showed that it is possible to achieve favorable outcomes with early management in functional Class III malocclusion patients.
