Avaliação cinemática em cães: revisão

Kinematics is the geometry of motion, including displacement, speed and acceleration, without considering the forces acting over a body. The use of kinematics is still very limited when we are evaluating dogs because of the high cost of the equipment, but the information obtained is objective and precise, what is essential for a trustful evaluation. Taking all this into consideration, this evaluation will describe some researches that used the method, specifying the final objective for each of them. By this analysis, we can conclude that kinematic studies, according to the characteristics of dog races, are necessary to explain how body structure and conformance may affect the function. Besides that, according to normative patterns of a population it is possible to study some diseases and treatment evolution

Avaliação econômica de diferentes composições veiculares empregadas no transporte rodoviário de madeira: estudo de caso

Transport is one the essential services for the development of most economic activities. In the forestry sector, the main transport used to carry wood from the forest to local consumption is road. The transport increases the producing costs of wood and may be responsible of a high percentage in the final price of the wood sold in the industry. To reduce the company’s costs and increase the efficiency of forest production those transport activities must be analyzed and improved. In that context, an economic analysis is the main objective of this work, evaluating three different types of log transport from a sawmill in São Paulo´s Southwest region. For this, a data collection was done to compound the costs and the incomes of timber transport, and that way, to do the economic analyses of each transport. The monitoring activities were done in the second 2013 half-year and the research achieved economic viability results utilizing tools and methods of Economic Engineering

Avaliação do efeito do tratamento com surfactante químico e Pseudomonas aeruginosa LBI na toxicidade de solo contaminado com óleo lubrificante usado

Petroleum and its subproducts are considered a treat for the environmental quality because of the many environmental accidents that may occur during exploitation, transport and storage. A common remediation technique used in the contaminated areas is based on the use of surfactants, mainly the chemical ones, because they have low production costs. In the other hand, some microorganisms have indicate capacities of producing surfactants that emulsify substances and as result, offer a bigger contact surface for the microbiota degradation. This biossurfactants stand out in comparison with the chemical surfactants because they present lower micelar concentration values, are more tolerant for temperature and pH variation, because they are biodegradable, have low toxicity, higher emulsification and hydrocarbon solubilization index. In this way, after the surfactant application, a toxicity evaluation have to be made to identify the treatment effects. In soil, the activity of some microbial enzymes can show the environmental behavior of the contaminant under different treatment conditions. Dehydrogenase is one example of those enzymes that can demonstrate indirectly the effect of the pollutant on the soil microorganisms. The aim of this paper was to evaluate the toxicity after the addition of a surfactant and/or Pseudomonas aeruginosa LBI in soil contaminated by a mineral automotive lubricant. The previous mentioned bacteria are a potential biossurfactant (rhamnolipid) producer. In order to evaluate the toxicity, the dehydrogenase test was run. In this test, trifeniltetrazolium compound (TTC) after utilized as an electron acceptor, turns into trifenil formazan (TPF), that can be indirectly quantified using the absorbance measured by the spectrophotometer UV-visible. In this way, it was possible to quantify the dehydrogenase activity from the contaminated soil samples... (Complete abstract click electronic access below)

Desenvolvimento e caracterização de sistemas líquido-cristalinos acrescidos de geoprópolis (Melipona scutellaris): avaliação da bioadesividade

A alta incidência da cárie no Brasil vem despertando muito interesse para estudos que visem combatê-la. Tem-se observado a procura pela utilização de produtos naturais (plantas medicinais e resinas) que buscam atividade contra a principal bactéria causadora da cárie, que é o Streptococcus mutans, entre estas a geoprópolis (Melipona scutellaris). Todavia, apesar de os estudos mostrarem ação destes produtos de origem animal contra este micro-organismo, muitas vezes a baixa substantividade (bioadesão) deste material ao substrato determina uma baixa efetividade. Este estudo promoveu o desenvolvimento de um sistema líquido cristalino objetivando aumento da substantividade da própolis. Foram desenvolvidos sistemas constituídos por dispersão de quitosana, ácido oleico e álcool cetílico propoxilado e etoxilado (Procetyl® AWS), de acordo com o diagrama de fases ternário. Foram selecionadas 3 formulações, as quais foram submetidas a ensaios de microscopia de luz polarizada, análise de textura, bioadesão e reologia. Os resultados mostraram que os sistemas são viáveis para incorporação do extrato de própolis, aumentando sua bioadesão em ensaios in vitro

Avaliação do desempenho ambiental da produção canavieira com colheita mecanizada: contribuição à implantação de um sistema simplificado de gestão ambiental da propriedade

The consuming of the natural resources in the agricultural sector does not represent only one external factor of the productive process, but also it implies in a bigger cost for the production, justified for this environmental degradation. In view of the necessity of evaluating the sustainment of the agricultural businesses, the use of performance indicators if makes of extreme importance. The measurement of the support through environmentalindicators is one of the most accepted forms of performing the evaluation of one given agricultural activity. In this context, the Base System for Eco-certification of Agricultural Businesses (Eco-cert Rural) developed by the Embrapa Environment at Jaguariúna/SP, has for purpose to present a method of evaluation of the agricultural businesses, not only of the point of view of the ecological performance, as well as considering the social, economic and organizational aspects. Through the analysis of the performance of the activity and the regularization of the disconformities found, it makes possible the eco-certification of the activities in the varied existing protocols, offering technologies designed to the sustainable development of the agricultural businesses. Using Eco-cert.Rural, this work evaluated the contribution of the use of mechanized harvest in sugar cane handling, front to the traditional system of manual harvest, using the fire. In the Sugar Cane Activity General Performance Index, Agrícola Rio Claro scored 2,08 of a maximum of 15. Amongst all the indicators, those wich reached performance worse had been related to the Use of Energy and the Income, by increasing fossil fuel consumptiom, and implying income concentration due to resignations of rural workers. However, the improvements on the environment quality by supressing manual harvest through fire are very significant. Beyond the great reduction in...(Complete abstract click electronic access below)

In recent years a great worldwide interest has arisen for the development of new technologies that enable the use of products with less environmental impact. The replacement of synthetic fiber plants is a possibility very important because this fiber is renewable, biodegradable and few cost and cause less environmental impact. Given the above, this work proposes to develop polymeric composites of epoxy resin and study the behavior of these materials. Both, the epoxy resin used as matrix in the manufacture of sapegrass fiber composite, as tree composites formed by: epoxy/unidirectional sapegrass long fiber, 75% epoxy/25% short fiber, by volume, and 80% epoxy/20% short fiber, by volume, were characterized by bending, and the composites produced with short fibers random were inspected by Optical Microscopy and Acoustics Inspection (C-Scan). For the analysis of the sapegrass fiber morphology, composites 75% epoxy/25% short fiber (sheet chopped) and 80% epoxy/20% short fiber images were obtained by optical microscope and the adhesion between polymer/fiber was visualized. As results, the flexural strength of composites epoxy/unidirectional long fibers, 75% epoxy/25% short fiber and 80% epoxy/20% short fiber were 70.36 MPa, 21.26 MPa, 25.07 MPa, respectively. Being that composite showed that the best results was made up of long fibers, because it had a value of higher flexural strength than other composites analyzed

Avaliação do efeito da gastrectomia na motilidade e no esvaziamento gástrico em ratos por biosusceptometria de corrente alternada

The study of gastrointestinal tract (GIT) functions is necessary due to the increasing number of pathologies associated with it. Directly influencing the quality of life, the gastrointestinal tract provides a number of parameters that, when analyzed, allow us to describe its dysfunctions. Thus, many techniques can be combined to obtain these properties related to the GIT. However, these techniques are often invasive, require surgery, catheter insertion, or to build a temporal model of these functions, require the sacrifice of animals in a series of data collection. The technique used in this study has the advantage of having a low operating cost, being free of ionizing radiation, non-invasive and is known as biosusceptometry AC (BAC), used to evaluate the properties of the GI tract by monitoring the position and concentration of materials magnetically marked. The sensor consists of two pairs of coils, one reference and one for detection. A fixed base line separates the sensing and reference coils, and also functions as support for the instrumentation. It is also important to note that the detection coils are arranged in a first order (subtraction) gradiometric way. The objective of this study was to analyze the effects of gastrectomy in gastric emptying and gastrointestinal transit time of solid food in rats using a BAC system associated with magnetic markers. To realize this study was constructed a dedicated BAC sensor, built to analyze these GIT properties. Data acquisition was obtained by aligning the magnetic sensor with the stomach and colon of the animal at pre-determined intervals. Thus, when approaching the magnetic material of the sensor, the balance created between the two sides of the sensor is broken. This imbalance can be measured, digitized and acquired. Tracer was used as a ration magnetically marked with ferrite... (Complete abstract click electronic access below)

Biosusceptometria de corrente alternada para avaliação do trânsito gastrintestinal de alimentos líquidos em ratos

The gastrointestinal tract is the main route of nutrients absorption and drugs delivery. Is important to know the parameters related to the tract, like gastric emptying and gastrointestinal transit, in order to better understand the behavior of different kind of meals or drugs passing through the GIT. Many techniques are used to study these parameters, such as manometry, scintigraphy, phenol red, activated charcoal and carbon-13 reading. However, these methods use radiation, are invasive and require animal sacrifice. As an alternative proposal, the Alternate Current Biosusceptometry (ACB), a magnetic technique, has proved to be effective for these studies with small animals, in a noninvasive way, low cost, radiation free and avoiding the animal death. Associating the ACB to magnetic micro or nanoparticles used as tracers, it is possible to observe the meal behavior inside of the GIT. Focusing meanly on liquid meals digestion, this paper had the objective to evaluate the efficiency of the ACB technique in gastric emptying and gastrointestinal transit evaluation of liquid meals in rats. To perform the experiments, magnetic nanoparticles (ferrite, MgFe2O4) were used on a 1,5 ml solution introduced by gavage on similar weight and age rats. The sensor made by 2 pairs of coils, capable of generating and detecting magnetic fields, creates a field on the interest place and when this field is in contact with the marked meal, it changes, resulting on a variation of the measured voltage. The voltage variation is analyzed and is obtained a particle concentration on the interest region. The results showed that is possible to apply the ACB technique on the GIT evaluation of liquid particles digestion, gastric emptying and meal cecum arrival time curves were obtained and from that, is possible to observe a pattern of gastrointestinal transit. Both mean process time values were acquired, proving the technique capability of ...
