Avaliação microbiológica da superfície muscular de carcaças ovinas durante as operações de abate em matadouro

In order to evaluate the hygienic-sanitary conditions of lamb carcasses for human consumption, this study aimed at quantifying populations of indicator microorganisms, such as: mesophiles and psychrotrophs, molds and yeasts, Escherichia coli, Staphylococcus spp. and at identifying pathogenic microorganisms (Salmonella sp. and Listeria spp.). The study was conducted in one lamb slaughterhouse located in the State of São Paulo. Swab samples were collected from muscle surface of forequarter and hindquarter regions of 30 half-carcasses after skinning, evisceration and washing processes. Population counts were between the following values in log10: 2,00 ± 0,32 and 2,59 ± 0,76 UFC/cm2 for mesophiles; 1,52 ± 0,98 and 2,35 ± 1,17 UFC/cm2 for psychrotrophs; 0,75 ± 0,87 and 1,23 ± 0,97 UFC/cm2 for molds and yeasts; 0,00 ± 0,00 and 0,31 ± 0,84 NMP/cm2 for Escherichia coli and 1,75 ± 0,71 and 1,95 ± 0,68 UFC/cm2 for Staphylococcus spp. Salmonella sp. and Listeria spp. were not detected from any of the sampled points. These results indicate the necessity to improve the hygienic-sanitary conditions.

Boas práticas de laboratório e biossegurança: prevenção dos riscos ergonômicos

El control de los riesgos ergonómicos es parte del paquete de medidas de Buenas Prácticas de Laboratorio y Bioseguridad. De este modo, la mala postura, la iluminación o ventilación inadecuadas , prolongada jornada de trabajo, la monotonía y la actividad repetitiva, intensa rutina, el control de la productividad , el estrés y el trabajo por la noche son factores a los riesgos ergonómicos. Como se relacionan a los elementos físicos y de organización también pueden interferir con la comodidad y la salud del personal de laboratorio. Riesgos ergonómicos no sólo pueden generar trastornos psicológicos y fisiológicos que causan graves daños a la salud, sino también comprometer la productividad del laboratorio y reducir el equipo de seguridad , ya que producen cambios en el cuerpo y el estado emocional, tales como trastornos o lesiones relacionadas con el cansancio físico producido por el trabajo repetitivo, dolor muscular, alteraciones del sueño, diabetes, trastornos de los nervios , la taquicardia , las enfermedades del aparato digestivo (gastritis y úlcera ), tensión, ansiedad, problemas de espalda y la hipertensión. En este trabajo se propone una secuencia de actividad laboral (gimnasia) en el intervalo de tiempo pequeño, respetando las instalaciones y el espacio físico disponible en el ambiente del trabajo, como una estrategia para mejorar la calidad de vida laboral, para aumentar la productividad, mejorar la disposición a trabajar y para aumentar el conocimiento del cuerpo y de la interacción social.

Início de ativação muscular de estabilizadores primários e a capacidade física para avaliar estabilização lombo-pélvica

Introduction: Due to the high incidence of low back pain without apparent cause, different approaches to evaluate the lumbar instability has been proposed, such as surface electromyography to determine pre-activation and the ability of lumbar stabilization through functional physical assessment. In this context, the objective of this study was to evaluate the early activation of the primary stabilizing muscles in subjects without low back pain, with different physical abilities function (CFF). Method: Study participants were 20 subjects with 19.8 ± 1.4 years, 55.7 ± 8.8 kilos, 1.66 ± 0.08 m, of both sexes. The subjects underwent six Tests Physical Function (TFF) and the Test of Fast Moving Flexion Arm (TMRFB) to capture the electromyographic activity of the lumbar multifidus muscles (LM) and internal oblique - lower fibers (HI). Were assigned weights for each functional test and the result of the physical capacity of the final functional subject ranged from 0 to 100%. In the analysis of TMRB was considered the onset time of activation between the ML and HI. Results: Regarding TFF 2 (10%) subjects were considered to have normal physical capacity, 6 (30%) with good physical ability and 12 (60%) with regular physical capacity or poor. As for TMRFB average values of initiation of muscle activation in 75% of subjects were within the limits to characterize the condition of pre-muscle activation. Conclusion:The results obtained in the TFF were low compared with the CFF of asymptomatic subjects evaluated. This fact does not mean that the condition of stabilization of the subject is appropriate. However, the results obtained in the electromyographic examination to suggest that 25% of asymptomatic subjects tested did not have a proper condition of lumbar stabilization.

Força muscular e massa corpórea de ratos Wistar

The use of rats in studies that seek to monitor the effects of physical exercise is fairly common, even in works that make use of overload. However, the correct determination of the training load is critical to success of studies. Thus, with the objective of verifying the correlation of total body mass of the rats with their respective strength, and the correlation of the 1RM test with test repetitions, 40 rats, 90 days old and weighing average 0,49 pounds underwent a program of adaptation to the water and then were subjected to tests to determine the maximal and submaximal loads. After measuring the total body mass and maximal and submaximal strenght, it was possible to observe directly proportional relationship between maximum strenght and total body mass of 0.97 (P ≤ 0.01), being the maximum muscle strength equivalent to 109% of the total body mass. Between muscle strength and mass submaximal muscle strength was also found direct correlation between the variables, allowing to conclude that the submaximal strength test and total body mass are effective tools in determining the training load of rats.

Influence of wood moisture content on modulus of elasticity on tension paralllel to the grain of brasilian species

Periodically, when necessary, standard documents are revised in order to analyze inconsistencies and to include considerations according new realities verified. In this sense, aiming to quantify the wood moisture content influence on modulus of elasticity, it was applied tension tests parallel to the grain for six specimens of different strength classes of wood, considering nominal moisture of 12, 20, 25, and 30% in Brazil. The present paper examine the adequacy of the current Brazilian standard ABNT NBR7190:1997, in review, about the adoption of a first degree equation to describe the influence of wood moisture content for timber structures design. It was obtained a new first degree equation which leads to statically equivalent estimations when compared with results by ABNT NBR7190:1997 equation. However, as recommendations it could be maintain the current expression for the next text of the referred document review, without prejudice to statistical significance of the estimates.
