Pecuária e agroindústria de exportação na Amazônia: dinâmicas e perspectivas

Este trabalho tem por objetivo analisar a dinâmica recente da pecuária da Amazônia. A chegada da agroindústria de exportação esta promovendo uma revolução na pecuária regional, em termos de transformações técnicas para oferecer matéria prima de qualidade e com preços competitivos. Mas a principal mudança pode ainda ocorrer na questão ecológica que envolve a atividade na região, uma vez que a agroindústria de exportação representada pela empresas JBS, Bertin, Minerva, Marfrig e Independência, tem submetido a produção de carne bovina da região às exigências do mercado internacional: a certificação de um produto “legal”, sem dar origem a desmatamentos. O resultado pode ser uma redução no desmatamento e um aumento de produtividade via incorporação de novas tecnologias na pecuária.

Influence of the resistance training on heart rate variability, functional capacity and muscle strength in the chronic obstructive pulmonary disease

Background. The chronic obstructive pulmonary disease (COPD) is associated with the strength and resistance decreasing in addition to the dysfunction on autonomic nervous system (ANS). The aerobic training isolated or in association with the resistance training showed evidence of beneficial effects on an autonomic modulation of COPD; however, there are no studies addressing the effect of isolated resistance training.Aims. This study aims at investigating the influence of resistance training on an autonomic modulation through heart rate variability (HRV), functional capacity and muscle strength in individuals with COPD.Design. Clinical series study.Setting. Outpatients.Population. The study involved 13 individuals with COPD.Methods. The experimental protocol was composed by an initial and final evaluation that consisted in autonomic evaluations (HRV), cardiopulmonary functional capacity evaluation (6-minute walk test) and strength evaluation (dynamometry) in addition by the resistance training performed by 24 sessions lasted 60 minutes each one and on a frequency of three times a week. The intensity was determined initially with 60% of one maximum repetition and was progressively increased in each five sessions until 80%.Results. The HRV temporal and spectral indexes analysis demonstrates improvement of autonomic modulation, with significant statistical increases to sympathetic and parasympathetic components of ANS representing by SDNN, LF and HF. In addition, it was observed significant statistical increases to shoulder abduction and. knee flexion strength and functional capacity.Conclusion. The exclusive resistance training performed was able to positively influence the autonomic modulation; in addition it promoted benefits on cardiorespiratory functional capacity and strength benefits in individuals with COPD.Clinical Rehabilitation Impact. This study could contribute to clinical and professionals researchers that act with COPD, even though the resistance component of pulmonary rehabilitation presents consensual benefits on several healthy indicators parameters. There is no evidence about the effects on HRV before. Moreover, this study showed, on clinical practice, the HRV uses as an ANS activity on sinus node evaluation and highlights further importance on scientific context.

A filosofia do direito no sistema filosófico hegeliano

The Hegelian philosophy is presented as a progress in relation to other philosophies and it offers to take in itself all the other demonstrations. Thereby, Hegel intends to carry out his philosophical effort towards the establishment of a philosophical system. It is a comprehension recognized and exposed by Hegel in his doctoral thesis, i.e., that philosophy only becomes possible as a system. In this sense, the treatment dispensed to each one of his works necessarily evokes a relationship with all other. An work taken in isolation gets the feeling that something else should be presented, however, every work written by Hegel also contemplates a relation with his other works. In this sense, the objective here is to considerate Hegel’s Philosophy of Law in his philosophical system seeking to explicit its specific place, as well as its transit among the works of the thinker as a whole. The Philosophy of Law finds its particular moment in the ambit of the objective spirit or during the subjective spirit’s effectuation. However, it is assumed here the perspective that the Philosophy of Law represents, as the objective spirit does, a moment of mediation as well as a there-being whereby the absolute spirit’s effectuation would happen. Furthermore, Hegel’s Philosophy represents the presentation of what he considers as extremely important in philosophy, that is precisely, the need to sublate the separation between man and the world. It is not enough for Hegel, the affirmation of the being and the thinking in itself, but it is required to confirm them in their being other that will be evinced being itself. Thus, Philosophy is given as a reconstruction or as the factual knowledge as a science ceasing to be so only love of learning. This means in other words that philosophy deals with the world, in the world and for the world being much more than a speech to the world to be the talk of the world itself. If philosophy is the owl of Minerva who always arrives late, she does it for the reasons of the other to be recognized.

Salivary cortisol response to concurrent strength and high-intensity aerobic exercise: a pilot study

Aim. The aim of this pilot study was to compare strength performance and salivary cortisol levels response during a single strength session, and a strength session after 30 min of high-intensity aerobic exercise (concurrent condition).Methods. Saliva was collected from 7 male subjects, before and after all exercise bouts, and the maximum number of repetitions (MNR) and total volume (TV) in the different conditions assessed.Results. The MNR and TV were reduced in concurrent condition compared with control condition. Strength exercise in the concurrent condition induced higher salivary cortisol in relation to strength exercise or to and high-intensity aerobic exercise, separately.Conclusion. The different salivary cortisol profile in response to concurrent exercise reflects the faster reactivity of the hypothalamic-pituitary-adrenocortical system in this circumstance.

Urbanização de favelas: da espontaneidade à cidade formal

O presente Trabalho Final de Graduação analisou projetos de urbanização de favelas em paralelo com algumas urbanizações feitas nos tecido das cidades medievais que também possuem um traçado inicial de origem espontânea. A partir dessa análise, a pesquisa teve como objetivo a busca de experiências técnicas e de gestão, a partir de bases bibliográficas e visitas em campo, nesses locais de diferentes contextos e, a partir disso, discutir soluções urbanísticas que foram bem‐resolvidas ou dificuldades encontradas nas intervenções. A metodologia empregada para a análise baseou‐se na revisão bibliográfica através das bibliotecas da Universidade Estadual Paulista, da Universidade de São Paulo e do Centro de Documentação da Câmara Municipal de Évora, além do acesso a bibliotecas digitais, como a Base Dedalus da Universidade de São Paulo, a Biblioteca Digital da Universidade Federal de Minas Gerais, a BAE da Universidade Estadual de Campinas, a Minerva da Universidade Federal do Rio de Janeiro, a BU da Universidade Federal de Santa Catarina, BIB da Universidade de Évora e a Biblioteca Nacional de Portugal. Os resultados que foram obtidos buscaram responder perguntas como: quais as questões interessantes a se considerar a partir da análise do projeto – técnicas e de gestão? No caso das favelas, quando houve a remoção, isso foi feito por motivos técnicos pertinentes? E a questão da acessibilidade diante de casos de uma ocupação em encostas com acessos perpendiculares às curvas de nível? Como tornar o local acessível a todos? Isso já foi alguma vez pensado e solucionado? Quais as situações que devem ser observadas para se determinar se deverá ter ou não uma realocação das famílias? A partir dessa avaliação buscou‐se criar, ainda que minimamente, subsídios teóricos para novos projetos de urbanização e entender a efetiva importância sociológica na construção do “habitat humano”

Mapeamento geológico-geontécnico de trecho da estrada vicinal na Serra de Itaqueri, Charqueada (SP)

Geological-geotechnical problems affecting escarps as well as embankment and fill slopes of roads and motorways may generate different types of unsteadiness, which are mainly arisen from the deficient knowledge about the physical environment. This results in unsuitable engineering projects and inadequate executions, which can be worsened by an occasional inappropriate maintenance of the construction. A geologically-geotechnically characterization of escarps and slopes is crucial in order to prevent these problems. This work deals with a geological-geotechnical study of 1:10.000 scale mapping in a stretch of a local road (CHQ-40) at the Serra de Itaqueri, Charqueada town, State of São Paulo. The stretch is known by several physical problems as erosion and mass movement. The methods of study were based on an integrative analysis of the diverse elements of the physical environment by using aerial photographs - to obtain the physiographic compartmentalization of terrain units - as well as field work - to accomplish the evaluation of the units by employing sketch lists. To achieve this, we selected several techniques in order to identify and classify different types of existing problems as erosion, landslide in embankments and fill slopes, rockfall, block rolling, among others. We also included the analysis of soil horizon, thickness and composition. The geological-geotechnical mapping resulted in six units: 1- Sandstones in cuesta’s backhill; 2 – Basalts in cuesta’s front; 3- Sandstones in cuesta’s front; 4 – Talus and colluvial deposits at cuesta’s foothill; 5- Sandstones of the Piramboia Formation in hillside; and 6 – Colluvial soil in the hill top. A characterization of the geological-geotechnical units is detailed, coupled to the cartographic material. Other cartographic products elaborated for this study included 1:10.000 maps of hypsometry, slope and curvature

The influence of different implant surfaces on osseointegration in diabetes: a systematic review of the literature

AIM: The aim of this study was to evaluate, through a systematic review of the literature, the effects of different implant surface modifications on osseointegration in diabetic subjects. METHODS: A search was performed of the PubMed database, using a combination of the following keywords: “Implant surface” OR “Dental implants” AND “Diabetes” OR “Hyperglycemia”. Papers published in English between January 1960 and November 2013 were selected. All experimental models were considered in this search, but case reports and in vitro studies were excluded from this review. RESULTS: The initial search identified 182 articles. After reading the titles and abstracts, 39 articles were selected for full reading. Finally, 4 papers were selected after evaluation of all the papers, and these papers are discussed in this review. Due to the methodological heterogeneity of the selected studies, it was not possible to perform a meta-analysis of the data. CONCLUSION: It can be concluded that although the benefits of surface modifications present in individuals with diabetes have biological plausibility, there is little evidence of the benefits of these modifications.

Treatment of severe facial asymmetry secondary to osteochondroma of the mandibular condyle: case report

Osteochondroma (OC) is the most common benign tumor of long bones. However it is rarely found in the facial skeleton, being the coronoid process and mandibular condyle the most affected sites in this region. It basically consists in bone growth covered by cartilage. The etiology is still controversial: neoplastic, developmental, reparative and traumatic origins have been discussed in literature. The treatments of these lesions include total condylectomy or local resection of the lesion. This paper aims to report a case of a patient with history of trauma and possible fracture of the mandibular condyle in childhood, which in youth developed dentofacial deformity with severe facial asymmetry. The treatment consisted of resection of lesion both with maxillary and mandibular osteotomies associated with graft from the iliac crest bone. Actually, the patient is with a favorable aesthetic, without functional deficit and absence of lesion’s recurrence.

Immunoexpression of angiogenesis and proliferation markers in patients treated with cyclosporin A

In the present immunohistochemical study, the expression of vascular endothelial growth factor, nitric oxide synthase 1 and 3, and Ki-67 in the gingival tissues of renal transplant patients treated with cyclosporin A was assessed. Gingival overgrowth (GO) frequently occurs in transplant patients receiving immunosuppressive drugs such as cyclosporine and this gingival inflammation might play an important role in the pathogenesis of drug-induced GO. Twenty-eight human gingival biopsies were taken from healthy patients with chronic periodontitis (N.=14 control group), and from renal transplant recipients treated with cyclosporin A (N.=14 test group). The retrieved specimens were immunohistochemically processed and stained for vascular endothelial growth factor, nitric oxide synthase 1 and 3, and Ki-67. The levels of vascular endothelial growth factor, nitric oxide synthase 1 and 3, and Ki-67 were found to be significantly different among groups (P>0.001), with patients treated with cyclosporin A showing higher levels of all the analyzed markers compared to control group. In summary, the data from this pilot study suggests that the investigated factors have a role in the inflammation processes associated to immunosuppressive therapy. However, further studies with a larger sample population need to be conducted for an exhaustive knowledge of the mechanisms leading to GO.
