Deposição de nutrientes na carcaça de girinos de rã-touro

The objective of this work was to determine nutrient deposition on the carcass of bullfrog (Lithobates catesbeianus) tadpoles using a nonlinear model. A total of 2,700 tadpoles with an average weight of 0.039 g were used. Commercial ground feed containing 55% crude protein was offered ad libitum. The animals were weighed and evaluated every ten days for analysis of crude protein, ether extract, water, and mineral salt contents. The parameters of the Gompertz model were estimated by the modified Gauss-Newton method, and the deposition rates (g per day) over time were calculated by the resulting equation. The values found for the parameters of the Gompertz equation, used to describe nutrient deposition on tadpole carcass, showed biological interpretation. Maximum deposition rate (t*) was observed on the 36.2331th day for protein, on the 37.1420th day for water, on the 35.2971th day for mineral salt, and on the 41.3547th day for fat. Nutrient intake from the diet is higher than the deposition rate on the tadpole carcass.

Implantação iônica por imersão em plasma e deposição de filmes finos poliméricos provenientes da mistura hexametildisilazano/argônio

Thin polymeric films deposited by plasma are very atractive for many industrial and scientific applications, in areas such as electronics, mechanics, coatings, biomaterials, among others, due to its favorable properties such as good adhesion to the substrate, high crosslinking, nanomectric thickness, homogeneity, etc. In this work, thin films were deposited by plasma immersion ion implantation and deposition technique from a hexamethyldisilazane/argon mixture at different proportions. These films were subjected to several characterizations, such as, contact angle, which presented values near to 100 degrees, surface energy, with values near to 31 mJ/m2, hardness with values between 0.7 and 2.6 GPa, thickness from 100 to 200 nm, refractive index from 1.56 to 1.64, molecular structure presenting the following functional groups in the infrared spectra region: CHx from 2960 to 2900 cm-1; Si-H around 2130 cm-1; CH3 in Si-(CH3)x around 1410 cm-1; CH3 in Si-(CH3)x in 1260 cm-1; N-H around 1180 cm-1; CH2 in Si-CH2-Si bonds around 1025 cm-1; Si-O in Si-O-Si from 1020 to 1100 cm-1; Si-N in Si-H-Si bonds around 940 cm-1; CH3 in Si-(CH3)3 in 850 cm-1; Si-C bonds in Si-(CH3)2 around 800 cm-1; and Si-H in 680 cm-1 . From these characterizations, it was possible to conclude that the concentration of argon or hexamethyldisilazane in the mixture changed the resulting polymer

Análise da deposição de filmes finos semicondutores de GaN e GaN e Ga1-xMnxN preparados por sputtering reativo

Thin films of Ga1-xMnxN have great interest in its potential for control of electron spin (spintronics), in most cases this material is synthesized by techniques that have a high degree of control the deposition parameters, such as molecular beam epitaxy (MBE) and deposition of metalorganic chemical vapor deposition (MOCVD). The sputtering technique is an alternative route to produce such materials. Here we study the film deposition Ga1-xMnxN by reactive sputtering technique and apply enhancements such as a glove box, a residual gas analyzer and temperature control system, in order to growth films epitaxially using an analysis of the preconditions of films analyzed by spectroscopic techniques and microscopic. These procedures helped to improve the technique of deposition by cleaning substrates in an inert environment, and by the analysis of trace gases and heating the substrate holder as explained in the literature. Through the applications and comparisons it can be pointed out that the technique has the advantage of its simplicity and relatively low cost compared to MBE and MOCVD, but produces polycrystalline material

O futebol sobre a ótica do tema transversal trabalho e consumo

The cross-cutting themes, which are characteristic express concepts and values of citizenship and correspond to important and urgent issues to society, should be treated within the school context , for all disciplines . Just like football, specific content of physical education, which most often is approached only by the technical and tactical aspects. The aim of this study was to analyze football from the perspective of labor and consumption and to propose activities for teachers to this content and theme in physical education classes. We investigated, in particular, the influence brands, media and the effect of the globalization phenomenon in this sport, and later thematic activities. The methodology used was qualitative type, which is from a thick description of the details about the situation analyzed and evaluated. In the first step a literature survey was conducted to understand and analyze the topic of this work. In the second, the activities were prepared, with the teacher ways to treat football from the perspective of labor and consumption from the themes presented in the goal. The activities were directed to students in the 9th grade of elementary school. It is expected that with the study, football can be see addition to the procedural dimension in class and the teacher values the critical training, and labor relations and consumption Football and any other content of school physical education. Activities that assist teachers in their future projects, jobs and classes. It is also hoped that the sport can be studied and understood both historically and critically in Brazil, the football country

Análise dos efeitos das deformações estruturais sobre a transferência transversal de carga em um veículo do tipo fórmula SAE submetido a uma aceleração lateral constante

This paper studies the frame deformations on a formula SAE vehicle in steady-state cornering and its influence on the lateral load transfers and, consequently, on the tires normal loads due to the applied lateral load. For a vehicle with a perfect rigid frame, the vehicle mass, the position of the center of gravity and the suspensions are the only factors responsible for the load distribution between the tires. When the frame deformations are no longer negligible, the frame deformations affect the loaddistribution between the tires. The frame flexibility turns it able to behave as an additional set of springs to the suspension system, thus changing the behavior of the set. This paper describes howit happens and suggests ways to minimize this phenomenon

Tema transversal saúde na escola: diagnóstico e possibilidades

Introdução: A sociedade brasileira tem sofrido grandes transformações nessas últimas décadas e o papel da escola e sua importância também. Com a queda da Ditadura Militar, que vigorou de 1964 até 1985 e com a promulgação da Constituição da República em 1988, que teve como um dos objetivos principais a inclusão social, entre outras iniciativas no âmbito das políticas educacionais, foi dado início à elaboração dos Parâmetros Curriculares Nacionais, cuja primeira publicação se deu em 1997. Assim, além das disciplinas tradicionais como: Língua Portuguesa, Matemática, História, Ciências Naturais, Geografia, Artes e Educação Física, a escola também deveria trabalhar os chamados Temas Transversais: Meio ambiente, Ética, Pluralidade Cultural, Saúde, Orientação Sexual e Trabalho e Consumo, temas esses, que devem permear toda a prática educativa. Como será que as escolas vêm desenvolvendo a proposta de Temas Transversais? Será que a saúde é uma preocupação? Se a resposta for afirmativa, de que modo ela vem sendo conduzida? Objetivo: Baseado nos Parâmetros Curriculares Nacionais, este trabalho pretendeu avaliar a importância do tema transversal Saúde, bem como investigar os impactos desse documento na educação escolar do ensino fundamental. Metodologia: Para tanto, serão realizadas pesquisas bibliográficas e também documentais da escola, como o projeto político pedagógico e os livros didáticos utilizados. Conclusões: As conclusões elencadas neste trabalho são que o tema transversal Saúde é pouco trabalhado no ensino fundamental, devido, entre outros fatores, ao despreparo do professor e a concepção equivocada que ainda há nos educadores relacionando saúde às doenças e à higiene unicamente

Estudo da deposição de energia das radiofrequências através do método das diferenças finitas dependentes do tempo Monografia

Radiotherapy in veterinary practice is already known and widely distributed in large specialized centers of developed countries. In early 2000, there were about 30 radiotherapy equipment specifically designed for the veterinary clinic in the United States. In Brazil, the veterinary radiotherapy is still confined to research in universities, where most of the procedures is radiation therapy performed with superficial x-ray machines, with a voltage between 50 and 150 kVp, focus-distance surface (DFS) between 20,0cm and 40,0cm. As that occurs in human medicine, new research strengthens the development and prospects for the use of radiotherapy as a safe option for treating cancer in animals. This paper presents a methodology for calculating the exposure time for superficial radiotherapy procedures in veterinary medicine for small animals (dogs and cats). The dosimetric parameters of X-rays are determined using a spreadsheet tool for Microsoft Office Excel, developed in this paper for a device Dermopan 2, Veterinary Hospital of UNESP in Araçatuba. Using the worksheet helps the veterinarian to determine the time of exposure to radiation determined for each clinical case, optimize the workflow for professionals in veterinary radiotherapy procedures, which often lack the medical physics in team and at the time of radiotherapy. The correct use of spreadsheet decreases the chances of errors in dose rates of radiation, providing a higher quality of care
