Perfil epidemiológico dos pacientes internados na unidade de tratamento de queimaduras do Hospital Estadual de Bauru

Burns are frequent accidents, and they are among the major causes of morbidity and mortality in our society. In Brazil, statistical data on such lesions are relatively scarce, and they are concentrated in a few treatment centers. Data on such accidents allow for specific care to be timely and properly taken in order to provide patients with a better prognosis, in addition to enabling the development of prevention programs as well as fire-prevention safety laws. To characterize the epidemiological profile of users at the Burn Treatment Unit of Bauru State Hospital. Collection of epidemiological data through the e-pront system and from charts of burned inpatients from April 2005 to April 2010. During the studied period, 906 hospitalizations of burned patients occurred, with an annual average of 181.2 individuals. Their mean age was 28.4 years, with a predominance of males. The mean hospitalization period was of 27.6 days, with a median of 16 days and a maximum of 216 days; 14.7% developed to death, with the highest mortality rate in the first two weeks of hospitalization. Second-degree burns were the most frequent; 36.8% of the patients burned less than 10% of their body surface, and there was a gradual frequency reduction when a larger burned surface was taken into account; the greater the affected areas, the higher the number of deaths; 91% resulted from thermal agents, 6% from electric and 2% from chemical agents; scalding was the major cause among all agents, followed by alcohol associated with fire and direct flame. The major area affected areas were the upper limbs. The study shows the need for educational and preventive measures, particularly for the young adult population, by means of educational programs and prevention campaigns

Proteção de sistemas eletricos industriais: relés e suas aplicações em subestações

Electrical installations in industries involving high currents and voltages considered. On the other side is the common appearance of electrical failures, caused by human error, defects in electrical equipment or electrical installation aging itself. These failures are varied, those with the highest rate of occurrence and cause much damage to electrical installations, are overcurrent and overvoltage. Therefore there is a need to project a system that can detect and minimize possible effects caused by faults in electrical installations industries. Protection systems in electric industries emerge as an alternative to control especially voltage and current magnitudes. Engineered based on the functions of the relays, protection systems are an indispensable tool for any industrial substation. But the project of such systems becomes increasingly more complex, due to technological development. Electrical equipment not develop at the same speed that the protective devices (relays), making it indispensable knowledge of integration of technologies

Proposta de um dispositivo para ajuste automático da altura de uma cama hospitalar

This paper proposes a mechanical device to adapt a simple model of hospital bed used in the Emergency Department at Santa Casa of Guaratinguetá, allowing the bed’s height adjustment with electromechanical drive. This adaptation aims to introduce improvements in the routine work of nurses and reduce ergonomic problems stemming from repetitive strain during the transfer of patients to stretchers and wheelchairs, as well as providing more comfort to the bedridden patient. The device is mainly composed of: an electric induction motor used to drive the engine, a steel spindle with square thread, which allows axial displacement of the bed, a transmission system with pulleys and belt, which transmits power supplied by the motor to the spindle. The mechanism allows the height of the bed is regulated between 400 and 800 mm. The estimated implementation cost of this proposal is lower than the acquisition cost of a commercial hospital bed with the same features, which confirms the feasibility of the proposed solution

Análise da viabilidade econômica na implantação de inversores frequência em sistemas de bombeamento

The present work aims to conduct a study of the economic feasibility of the implementation of variable frequency inverters in pump systems with variable flow rates. The concern with the reduction of energy expenditure in industries raised in 2001 due to the energy crisis that hit Brazil at that time, forcing industries to reduce their electric costs under penalty of fines if this were not done (MOREIRA, 2008). Frequency inverter is an electronic device that allow greater control in the operation of pumping systems and also a reduction in electrical consumption, being a viable solution to achieve a reduction in energy consumption. For the development of this work, approaching important topics in pumping systems was necessary in order to make a correct choice of hydraulic pumping and also other components responsible for the operation of the system , such as electric motors and frequency inverters. In the case study, a theoretical analysis of the behavior of electrical consumption in systems with variable flow rates was performed, comparing when the system is operated via frequency inverters and when the system is operated without such a device. As expected, the result of the implantation of the device was quite satisfactory, and the primary goal of reducing energy expenditure was achieved. Also important to highlight the environmental issue of this work, as all forms of energy production affects nature in some way, achieving a reduction in consumption also contributes indirectly in environmental conservation

Utilização da instrumentação virtual em Labview para criação da interface gráfica do amplificador lock-in utilizado em estudos fisiológicos a partir da comunicação via porta serial

This work presents the development of a graphical interface to the Lock-in Amplifier, which is used in physiological studies on the motility of the gastrointestinal tract in rats and signal processing. With a simple and low cost instrumentation, the resources offered by the virtual interface of LabVIEW software allows the creation of commands similar to the actual instrument that, through communication via standard serial port, transmits data between a PC and peripheral device performing specific and particular needs in the amplifier. Created for the lock-in amplifier model SR830 Stanford Research Systems, the remote manipulation gives the user greater accessibility in the process of configuration and calibration. And, since the software is installed, there is the advantage of eliminating the need of purchase new devices to upgrade the system. The commands created were made to perform six basic modifications that are used in routine of the Biomagnetism Laboratory. The instrumentation developed has the following controls: Amplitude, Frequency, Time Constant, slope low pass filter, sensitivity and offset

Avaliação da auto-suficiência energética de reatores anaeróbicos aplicados ao tratamento de resíduos de uma cervejaria em escala piloto

This project aimed to analyze the feasibility of the methane yield associated to the anaerobic digestion of brewery residues, checking whether the energetic balance of the system is favorable. The methane yield efficiency was calculated for the parameters of two papers that treated solids with a particle-size <1mm. Theses solids are not degraded in conventional treatment systems. Calculations were based in the reactions of anaerobic degradation of the macromolecules that compose brewery residues, considering the theoretical production and the effective production of methane. The results were 50.44% and 52.86%. Regarding to the energy balance of the anaerobic treatment, we noted the high influence of the selection and operating regime of electrical equipment over the potential energy. The best situation, in which the energetic self-sufficiency was reached, was observed when using the mixer under an intermittent regime (1min/h), without employing the heating recirculator, for the maximum organic loading of 4.0 gVS/L.day (days 248-258). In this case, the system would generate an amount of energy equal to 0.0356 kWh/day, able to overcome the energy required by the equipment in about 6.5 times. Moreover, we also noted the interference of the application of different solid loadings in the reactors, once the application of the higher organic load generated 5 times more energy than the application of the smaller one

Análise do consumo de energia elétrica e da eficiência energética em uma indústria de processamento de madeira

In the industries of wood processing (sawmills), where timber is sawn in equipment such as band saws, circular saws, trowel, thicknessers, among others, that mechanically transform this resource and use of electric motors, which are not unusually poorly scaled working or overloaded, often a factor that is not found in these industries and has fundamental importance in the production process is energy efficiency that is achieved by both technological innovation and through all the practices and policies that aim to lower energy consumption, lowering energy costs and increasing the amount of energy offered no change in generation. For both during the design of an electrical installation, both overall and in various sectors of the installation, investigations are necessary, considerations and uses of variables and factors that put into practice the theme of energy efficiency. Therefore, in this paper, these factors were calculated and analyzed for a wood processing industry (sawmill) in the municipality of Taquarivaí - SP, namely: active power, power factor, demand factor and load factor. Where they were small in relation to the literature, these events that occur when devices are connected at the same time and due to the conditions of processing the wood, where the engines have large variations in electricity consumption during the unfolding of the same, due to efforts with the load and idle moments between each machining operation in the equipment

Acupuntura veterinária em pequenos animais

Acupuncture is one of the oldest forms of treatment, which is based in the grounds of Traditional Chinese Medicine. Despite the ancient history, it’s not completely widespread in Brazil, neither so comprehensive in veterinary medicine as used in humans. The technique of inserting needles into acupuncture points, can also be stimulated by heat, electrical stimulation or implants of metal, is mainly focused on neuromuscular disorders in small animals. The difficulty of comprehension of language and the lack of cientific bases restricted the possible applications of acupuncture. This work will address some of the clinical situations this complementary treatment can act, such as neurological, cardiorespiratory, reproductive, gastrointestinal, immunological, and postoperative intensive care

Proposta de uma metodologia de rebobinamento para converter motor de indução trifásico em monofásico

This paper proposes the conversion of a three-phase induction motor into single phase through rewinding its stator. It presents a methodology to calculate this rewinding process considering the constructive parameters of the, such as number of slots and number of poles, for instance. The operating principles of DC motors are highlighted to introduce the logic involved in the calculation of lap and wave windings. The construction of the stator three-phase induction motor generally uses the lap winding, which is also used in single phase to perform the conversion. The rewinding process is widely used for reconstruction of industrial and residential electric motors that have suffered damage or present flaws with use. Therefore, many three-phase electric motors that are discarded or disposed of could be recovered by the method described in this work for a purpose that contributes to energy efficiency or simply saving resources in single-phase uses
