Geologia e Mineralogia do Pegmatito Estanífero Cascavel, Mina Bom Futuro, Rondônia

A mina Bom Futuro situa-se na região centro-norte de Rondônia e inclui dois morros denominados de Palanqueta e Bom Futuro e as áreas aplainadas adjacentes. As principais lavras de extração de cassiterita ocorrem nos placeres circunvizinhos ao morro Bom Futuro, bem como nos depósitos primários situados no próprio morro. Esses depósitos primários restringem-se aos corpos de pegmatito formados em pelo menos dois eventos distintos. O pegmatito Cascavel pertence ao evento mais antigo e é composto por uma lente principal e um enxame de diques, veios e vênulas com atitude geral NNW/35oENE. Os corpos são maciços ou zonados, sendo que na lente principal foram reconhecidas três zonas distintas, sob a forma de leitos subparalelos entre si e com as paredes da lente. Do muro para o teto tem-se: zona do quartzo e topázio, zona do feldspato alcalino e Li-mica e zona granítica. Os minerais principais do pegmatito Cascavel são quartzo, feldspato alcalino (microclínio pertítico), topázio e Li-mica e os minerais subordinados ou acessórios são cassiterita, sulfetos (esfalerita, calcopirita, pirita, galena e estanita), zircão, monazita, wolframita, uraninita, columbita-tantalita e rutilo niobífero. O pegmatito Cascavel é do tipo complexo e pode ser incluído na família LCT dos pegmatitos a elemento-raro. O pegmatito Cascavel é de natureza subvulcânica e mostra relações espacial e temporal com os granitos peraluminosos tardios da Suíte Intrusiva Granitos Últimos de Rondônia.

Ocular ultrasonography and ultrasound biomicroscopy: applicability in clinical and ophthalmic surgery

With the advent of high frequency transducers, the use of ocular ultrasound has become widely used because it provides definitions of major ocular structures. This diagnostic tool is useful in the evaluation of ophthalmic injuries, and also used for qualitative and quantitative evaluation of intraocular and orbital lesions. It is a noninvasive, safe and fast, easy to use and can be performed in an awake animal. The ocular ultrasonography is indicated in cases of ocular opacity, when the ophthalmic examination cannot be done, and in eyes with ocular trauma or suspected orbital disease. Ultrasound biomicroscopy (UBM) is a diagnostic tool with high cost and sedation or general anesthesia is necessary, but has the advantage of evaluating structures poorly defined or visualized in the anterior segment of the eye. Therefore, this paper aims to show the importance of ocular ultrasonography and UBM to veterinary practitioners, and to demonstrate its advantages and indications in ophthalmic routine.

Alterações hematológicas associadas ao hifema em cães

Hyphema is an intraocular hemorrhage that can result from many ocular and/or systemic disorders. It is an important clinical sign, since it may appear in the initial stages of some diseases or haematological disorders, acting as an initial marker for early diagnosis. The hematologic disturbances that predispose animals to present hyphema are: Thrombocytopenia, von Willebrand Disease, Scott Syndrome, Disseminated Intravascular Coagulation and Hyperviscosity Syndrome due to Multiple Myeloma. Each of the differential diagnoses due to hematological changes from the appearance of hyphema in dogs shows clinical relevance and particular ocular signs

Piecewise Bounded Quadratic Systems in the Plane

In this paper we study the sliding mode of piecewise bounded quadratic systems in the plane given by a non-smooth vector field Z=(X,Y). Analyzing the singular, crossing and sliding sets, we get the conditions which ensure that any solution, including the sliding one, is bounded.

Mapeamento dos compartimentos de relevo do município de Estrela do Norte-SP e adjacências

The Geomorphology is to study the relevant object, which is the substrate where there are social relations, where society draws the natural resources for their survival and structure its immediate surroundings. In this context, the geomorphological map is currently considered as an important tool in landscape research. The landscapes of the city of Estrela do Norte-SP and surroundings consist mostly of geological substratum of sedimentary rock formations of Adamantina and Santo Anastácio (IPT, 1981a). Geomorphologically dominated by large reliefs of gently rolling hills tops and pedologicamente, the Oxisols and Ultisols Red-Yellow (Oliveira et al., 1999), which historically without proper management, formed a serious degradation of erosive framework in the study area. Thus, this study aimed to produce a map of the major compartments of the municipality Estrela do Norte-SP and surrounding areas, using techniques of digital stereoscopy. In relation to the procedures used in developing the mapping of geomorphological compartments, the main references were Tricart (1965) and Ross (1992). To prepare the mapping applied to refund technique - 3D through the ALOS / PRISM images...

Políticas públicas municipais de apoio a atividades econômicas em assentamentos rurais: uma análise em quatro municípios paulistas

This paper reports a master research that aimed to analyze the patterns of institutional relationships between local officials and communities of agrarian reform settlements in four counties of the State of São Paulo – Apiaí, Iaras, Promissão and Mirante do Paranapanema – particularly with regard to the types of support offered by the first to the economic activities in the settlements. In terms of methodology, we conducted a qualitative, exploratory and descriptive research, outlined in the format of multiple case study. Having like data sources the local officials responsible for institutional relations with the agrarian reform settlements, technicians agents of agencys linkeds to the land question, as INCRA and ITESP, and settled in leadership positions in rural settlements, we sought to evaluate the intensity, the types and quality of the (possible or actual) support offered by municipalities to economic activities inside the settlements. We sought to evaluate the results from theoretical lens formed around the notions of local development and the significance assumed by settlements in different locations. The results showed a fairly heterogeneous and, often, disparate in particular circumstances. It was evident, from the information collected, that a positive action of the municipal government in supporting the economic activities of the settlements is essential for the release of social energy based in settlements, enabling the realization of the "amalgam of possibilities" constructed from the implementation of rural settlements.
