Entre nativos e exóticos: a mestiçagem na construção de uma nova identidade na caprinovinocultura dos sertões

In the Northeastern Semiarid of Brazil, dynamic among creators of goats and sheep native and exotic bring a range of meanings. In addition to actual trade disputes, conflicts are waged in the realm of ideas, revealing different values and interests around the racial origin of these animals. Between these two segments lies most of the small farmers and the traditional Semiarid sheep and goat raising, based on the use of animals breed, arising from the dynamics of spontaneous crossings, own extensive creations characterized by reduced control over the herds, state which shows a marked contrast to the first two segments. Given that their influence on a traditional creations can result in improved production of small farmers, linked to different social sector research and extension have turned their efforts to construct possible arrangements that are satisfactory to the reversal of historical problems of the region, especially the use of animal miscegenation as a strategy for change. It focuses on the work of these actors, the forms of interaction between them, fulfill the role that ideas, values and attitudes in the face of the possibilities for sheep and goat raising that region.

A formulação de uma corrente urbanística: uma (re)visita às teses de Anhaia Mello para São Paulo

The present article aims to elaborate an objective analytical panel, initially from the 1920- 1930 when Luiz Ignácio Romeiro de Anhaia Mello, cathedratic in the urban question, started to quote a series of authors and American plans as references to their reflections, mainly when the point was the verticalization or not at São Paulo City. From a broad bibliographic research with the systematization of the register from the debate between Anhaia Mello, this article intends to point out how the transposition of the urbanistic conceptions to the academic environment happened and, at the same time, the legal normatization of the São Paulo City that resulted in the creation of a draft of the regulations for use and occupation of the soil. The systematizations and analysis were based in a broad reading of the bibliography and documental sources that refer to the proposed theme. The books of the library of FAU-USP, specifically the one from SAGMACS – Sociedade de Análises Gráficas e Mecanográficas Aplicadas aos Complexos Sociais ( Society of Graphical Mechanical-Graphic Analysis Applied to Social Complexes) -, aiming to select papers and the collection of Anhaia Mello´s family, so that a reconstruction of the intellectual and professional journey of the Urbanism Professor. The systematization of the collected data and posterior comparison with the bibliographical study was fundamental for the reconstruction of the reflection of Anhaia Mello about the ways of the urban streets and roads at Sao Paulo City should be lead to on the middle of the XX century having as a guideline the debate between Anhaia Mello – very common on the 1950s for less important countries when dealing with the organization of the size of industrial metropolis. It was possible to identify the crystallization of one urbanistic proposal for the city: the from Anhaia Mello, that bet on the reversion of the metropolitan cycle by stopping the urban growth by the application of the theoretical conception of the garden city.

Effect of mechanical cycling on screw torque in external hexagon implants with and without platform switching

This in vitro study evaluated the effect of mechanical cycling on the torque of retaining screw in external hexagon implants with platform switching (PS), regular platform (RP) and wide platform (WP). A total of 30 specimens were equally divided into 3 groups: PS, PR and WP. Each specimen was prepared with implants: 3.75 x 10 mm for RP group and 5.0x10 mm for PS and WP groups and its respective abutment with 32 Ncm torque. All groups were subjected to 106 cycles with 100 N (corresponding to about 40 months of chewing). The results were obtained with the reverse torque of each specimen and data were evaluated using ANOVA and Tukey test (p<0.05). The PS group showed statistically significant difference in screw removal torque (30.06±5.42) compared with RP (23.75±2.76) and WP (21.32±3.53) (p<0.05) groups; the RP and WP groups showed no statistically significant difference between them. It was concluded that the PS group showed higher reverse torque value, suggesting lower susceptibility of the abutment screw loosening.

De um subproduto industrial para um produto destinado à alimentação animal: produção de biomassa bacteriana

A grande diversidade das atividades industriais ocasiona durante o processo produtivo a geração de resíduos sólidos, líquidos e gasosos, que podem poluir e/ou contaminar o solo, a água e o ar. Embora existam regulamentos para o descarte desses resíduos, a inobservância às regras, a ineficiência dos tratamentos despoluentes e a inoperância de órgãos fiscalizadores permitem que, ainda hoje, sejam lançados ao ambiente grandes cargas de poluentes. Isso se aplica às indústrias de alimentos de origem animal. Felizmente, a visão dos empresários do setor vem mudando, na medida em que a imagem de uma empresa que conta com produtos e processos ambientalmente responsáveis representa parte das estratégias competitivas atuais. O objetivo deste trabalho foi demonstrar como um efluente industrial pode ser transformado em matéria prima para a obtenção de um produto com valor comercial, utilizando tecnologias reconhecidas pela indústria e a atividade microbiana. O efluente foi obtido em indústria de abate e processamento de tilápias, apresentado (valores médios) pH = 9,4, DQO = 1.127 mg/L, óleos e graxas = 1.166 mg/L, nitrogênio total = 813 mg/L, coliformes a 30–35o C = 1,0x105 NMP/mL, coliformes a 45o C = 0,41 NMP/mL, bolores e leveduras = 4,6x103 UFC/mL e, ocasionalmente, contendo Salmonella sp e Aeromonas sp. Os tratamentos físicos aplicados ao efluente incluíram gradeamento, filtração (50µm) e pasteurização (65o C/30 min). O cultivo de Rubrivivax gelatinosus foi realizado sob anaerobiose em reatores de vidro durante 7 dias, em temperatura ambiente (30±5o C) e 2.000±500 lux. A recuperação da biomassa foi feita por filtração tangencial (0,2 µm; 1,5 bar), centrifugação (3.400 g/30 min; 5o C) e liofilização (-40o C) e a pulverização foi realizada manualmente. A produção de massa celular atingiu 0,18 g/L, com produtividade de 0,0634 g/L.dia. O processo promoveu redução de 52% na DQO, 48% em óleos e graxas e 22% no nitrogênio total, gerando um resíduo com pH 7,9, livre de bactérias patogênicas e, portanto, apto ao descarte. O produto obtido apresentou cor vermelho escuro (L = 22,42; C = 14,22; h = 25,48), 4,55% de umidade, 57,39% de proteína, 11,08% de extrato etéreo, 4,05% de matéria mineral, 3,03 mg/g de oxicarotenóides, 20,27 NMP/g de coliformes a 30–35o C, <1,0 NMP/g de coliformes a 45o C, 1,2x103 UFC/g de bolores e leveduras e ausência de microrganismos patogênicos. Essas características apontam para um potencial pigmentante e nutricional positivo no produto, que pode encontrar aplicação na produção animal, com segurança microbiológica. Dessa forma, fecha-se um ciclo autosustentável que pode ser adotado na própria fonte geradora do resíduo industrial, permitindo a reversão de gastos com tratamento despoluente em receitas advindas da comercialização de um novo produto.

O efeito do consumo abusivo de alvool no torque de remoção de implantes de titânio

Studies have reported that alcohol may lead to imbalance in bone formation and resorption, however, its effects on osseointegration of titanium implants continues to be an inconclusive subject. In this context, the aim of this study was to make a biomechanical evaluation of the effect of abusive alcohol consumption on the removal torque of osseointegrated titanium implants. Male Wistar rats (n=30) were divided into two experimental groups (15 each) receiving only water (Control) or 36% alcohol solution oral administration. Thirty days later, all animals were submitted to titanium implant (2.2 mm x 4 mm) placement in the right and left tibiae. The surgical alveoli were prepared with a 2 mm drill mounted in a counter-angle hand-piece (20:1 ratio, 35 Ncm torque at 1200 rpm) under abundant cooling. Five animals from each group were euthanized at 15, 30, and 60 days. Tibiae were submitted to reverse torque analysis. Data obtained were submitted to statistical analysis by the non-parametric Kruskal-Wallis and Dunn Tests (p < 0.05). Animals in the alcohol group presented lower removal torque values when compared with control group animals for all periods tested (p < 0.05). It can be concluded that abusive alcohol consumption can reduce the removal torque of titanium implants placed in rat tibiae, suggesting that alcohol may interfere in the osseointegration process of titanium implants.

Aspectos clínicos influentes no planejamento das próteses sobre implantes tipo overdenture e protocolo

The aim of his study was to review the current scientific literature in order to discuss the surgical, prosthetics and psychological/psychosocial aspects during the treatment planning of edentulous patients, when a total fixed prosthesis or overdenture is indicated. To identify studies to take part in this review, a search was conducted for the following databases: PubMed, Dentistry and Oral Sciences Source, Journals@Ovid, SpringerLink, Wiley Online Library, Nature (NPG), Oxford Journals. It was used as descriptors: total fixed prostheses and overdentures. Inclusion criteria were: clinical articles, clinical case reports, case series, literature reviews and systematic reviews that addressed the study and comparison of total fixed prostheses and overdentures for a surgical- prosthetic planning. Exclusion criteria were: laboratory and in vitro studies and those whose first language was not English or Portuguese. Of a total of 454 articles, after an analysis according to inclusion and exclusion criteria, 76 articles were selected. During an implantsupported prosthesis rehabilitation with dental in edentulous patients, the use of alternative procedures appear to be effective when compared to more invasive surgical techniques, and thus, the amount of dental implants possible to install associated with prosthetic issues such as lip support, smile line, quantity and quality of mucosa, phonetics, etc., will allow an appropriate treatment planning to each clinical case
