The tof-guard neuromuscular transmission monitor and its use in horses

Quando da utilização de bloqueadores neuromusculares, já foi enfatizado na literatura médica humana, que é de vital imporância a monitoração do bloqueio neuromuscular e que estes agentes nunca devem ser utilizados sem a mesma. O objetivo deste estudo foi o de avaliar o uso do monitor da transmissão neuromuscular TOF-Guard em eqüinos. Para tanto, doze eqüinos foram separados aleatoriamente para receberem como bloqueadores neuromusculares o pancurônio ou o atracúrio. Todos os eqüinos foram pré-medicados com romifidina, induzidos com diazepam e quetamina e mantidos com halotano. Foi administrado o atracúrio ou o pancurônio, seguindo-se a apnéia e início da ventilação mecânica controlada. O tempo entre a administração do relaxante muscular e a obtenção de um bloqueio máximo (T1=0), o retorno do T1 para 25% e da razão do TOF para 0,7 e o tempo do retorno do T1 de 25 para 75% foram mensurados. Concluiu-se que é de grande importância a monitoração do bloqueio neuromuscular quando da utilização de um bloqueador neuromuscular não-despolarizante, uma vez que ela torna o ato anestésico e cirúrgico mais seguro, com a utilização de doses adequadas que inviabilizam a superficialização do bloqueio durante o procedimento cirúrgico. O monitor TOF-Guard mostrou ser uma boa opção para a monitoração do bloqueio neuromuscular em eqüinos.

Utilização de água pluvial para fins não potáveis: análise do atendimento da demanda pelo método de eficiências para dimensionamento de reservatório para diferentes regimes pluviométricos brasileiros

Brazil has about 12 % of a life´s essential resource: the superficial fresh water of the planet. However, today it is possible to observe the bad management of this resource, generating serious consequences on the quality that results in the loss of the use´s availability. In this scenario, the catchment of rainwater for undrinkable use is an alternative that has been broadly studied for the scientific community. When planning a system of rainwater catchment, the sizing of the required volume of the tank that will keep the water has a fundamental importance for the project, seeing that the supersizing of the tank can bring high costs and the undersizing can bring shortage in the water supply. This paper used a methodology based on two concepts: the harvesting efficiencies and the attending efficiencies of the system. This method takes as principle that exist a perfect demand that minimize the repayment time, condition that happened when the efficiencies are equal. Brazilian’s cities with different weathers and different rainfalls where chosen to simulate the attending for different demands for a typical residence. The data where parameterized according to the roof area and the number of residents, that way is possible that a future conference can be easily done and it also ensure results closer to the reality. The results showed that cities with a lower period of drought, even those with high level of rainfall on the raining mouths, have lower potential of water supply. The cities where the rainfall is more constant and also more high, even small roofs areas and small tank´s volumes – about half of the size compare to the cities with less propitious conditions – can generate high levels of water saving. With an eye to promote the environmental sustainability, the investment on projects for the catchment of rainwater is a good alternative

Sobre as considerações de uma concepção de um projeto de um forno cerâmico

The current competitiveness of the market has generated the need to minimize the cost of production companies in any field of activity, aimed at reducing the cost of production, the cost of purchasing and manufacturing processes interruption of manufacturing processes for possible maintenance. In this sense, companies are seeking methods to improve and streamline their production line. In ceramics industries, cooking the pieces is the portion of the production process that influences the total costs. The oven construction and maintenance represent a large portion embedded in the cost of the final ceramic product. The proposal for a type of oven for baking the parts that takes into account a better burning process, knowledge of the causes of disease and cost analysis of purchasing both of the constituent materials and labor for its construction, can be significant importance to the composition of final product costs or time analysis of ROI. It is proposed a streamlined design of an oven that takes into account the positive characteristics of the furnaces already built and that the experience has endorsed, and also others that are added at the end, lead to a reduction in production cost, the cost income and the number of pathologies arising from wear of the furnace along the lifespan. Therefore, according to the experiences gained over the years in the construction of furnaces and experience of manufacturing of ceramic, it is proposed a project that has an oven improvement over those now being built and that include, among other topics, economy in fuel burning, streamlining the building process

Metodologia para determinação de volume de detenção em pequenas bacias urbanas: o caso do córrego Wenzel, Rio Claro/SP

With the accelerated urbanization process of Brazil from the 50s, there was a disorderly occupation of spaces and consequent soil sealing. Unlike this growth, the support capacity of urban environments has not evolved in the same way, generating negative environmental impacts to the citizens. Among these impacts are the effects of flooding. In order to minimize the negative effects of extreme precipitation over cities, the government invests in corrective measures, like compensatory techniques on urban drainage, which have as a basic principle the retention and infiltration of the rainfall, dampening the peak flow and runoff. An example of applying these techniques in urban areas are the detention basins, commonly called large pools. The hydraulic design of these structures is dependent of complex data and variables, and projects involving small areas generally use simplified methods for defining the reservoirs volume of the storage (Tassi, 2005). One of these methods is presented in this study, which relates to the percentage of soil sealing to the specific storage volume (m³/ha) in combination by applying the hydrological model of the Rational Method and analyzing regional rainfall and soil occupation over the basin. Within this context, the basin of the Wenzel stream, which is located amidst the urban area of Rio Claro/SP, also presents the problems related to human occupation in its valley. Thus, by the method presented has been adjusted a curve correlating the percentage of impermeable area and the specific volume of a detention basin. For the current situation of Wenzel Basin with 82% of impermeable area, and return period of 10 years, the specific volume is 262.1 m³/ha. The presented method is consistent with the results of other studies in the area, and the expression obtained allows estimating the volume of storage required to match hydrograph pre and post-occupancy. It presents itself as a useful tool in the planning stage of...

Proposta de captação de água de chuva de para fins não potáveis em projetos residenciais

Water is an economic, strategic and social valuable resource of the utmost importance to society. This renewable natural resource is increasingly scarce with the growing of populations, industries and agriculture, in addition to the pollution surface and underground water and the waste have aggravated this situation. Investments in the sector of water resources so that this resource meets in quantity and quality the demand from its multiple uses, represent a significant portion of national and regional budgets. Therefore, the use of alternative sources of water capture can reduce the pressure on conventional public water supply systems. In this work was designed and executed a rain water collection system to a residence in the city of Barueri (SP), which can be applied to other residences. In this system, the rooftop of the residence was used as the waterproof and capture area. The gutter and the PVC conductors were used for driving the water to two connected reservoirs. The stored water was designed to address activities that are not potable, such as washing clothes and external areas and garden irrigation. The system showed economic viability, with 34-month return of investment time, wherein after that period, in addition to environmental and social benefits derived from the implementation of the project, the economy made with the payment of public supply rates should be considered. This rainwater capture system is inexpensive and uses materials available in the market. Therefore, its application to a greater number of households should be encouraged as a measure of sustainable water management

Estudo da viabilidade de produção da peça alimentação/ladrão para banheiras

The product development field daily works in the chase of new materials and technologies that fulfills the requirements of the consumer market. So, projects are developed in order to theoretically predict what will actually happen. The production of household appliance is not different. To provide a pleasant bath to the costumer, the manufacture of a bathtub counts on many components. With this in mind, this work goal is to study the possibility of production by plastic injection of the assembly water source/overflow pipe used in bathtubs and compare its production cost with the cost of the assembly acquired from third parties. The injection process is widely used on the world stage because of its numerous advantages, however, due to the high cost of the molds, it is important to estimate the time required for the return of the initial investment. To do this, a model was designed to examine its dimensions and then initiate the study of the possibility to inject the components with the available injection machine and the production cycle. With the results, it was found that there was a reduction in the cost of the finished assembly, but a very long time to return the initial investment due to the current financial scenery of the country
