Amilases e proteases constituem um dos principais grupos de enzimas industriais pelo seu amplo espectro de aplicações biotecnológicas. Elas podem ser obtidas a partir de fontes microbianas e com altos rendimentos por processos de fermentação em estado sólido (FES). Conhecer as características bioquímicas das enzimas é fundamental para adequação aos processos industriais. O objetivo do trabalho foi determinar a melhor temperatura para atividade das enzimas amilase e protease de Rhizopus oligosporus obtidas por fermentação em estado sólido utilizando farelo de trigo como substrato. Os melhores valores para atividade amilolítica e proteolítica foram obtidos nas temperaturas de 55 - 65 °C e de 50 - 60 °C, respectivamente. Estes resultados sugerem que as enzimas estudadas podem ser utilizadas em processos que empregam elevadas temperaturas.

El cuerpo presenta rastros de la historia y cultura de las sociedades por toda la historia de la humanidad. El presente estudio quiere, através de pesquisas sobre el cuerpo, entender como las modificaiones corporales han acompañado la historia del hombre, de las tribus antiguas hasta la atualidad y como son hoy los procedimientos de cambiar la forma física. Através de trabajo de campo conocer profisionales que hacen algunos tipos de modificaciones corporales y gente que las tienen en sus cuerpos, entender las razones para que cambien sus cuerpos permanentemente - en la mayoria de los casos - y como la idea de individualidad surge cuando se hace una marca personal en el cuerpo. Además, compreender el porque esas prácticas se están convirtiendo cada vez mas común en nuestra sociedade actual

Numerous studies in physical education and music's area have been conducted to improve the quality of life and health of people, all of them under physiological, psychological and social fields. Thus, when properly analyzed, both Areas are connected, because the movement itself, main subject of physical education, has a close proximity to the rhythm, an essential element of music. That's why it is important to discover the benefits of this relationship, because, in many of its practices, physical education makes use of music, for example, in aerobic gymnastic and dance classes. As a consequence, this study aims to investigate, through literature, the influence of music in physical activities and its imprinting in the states of mind and body of practitioners, as well as clarify the criteria for choice of songs that are used in such practice. This research occurred under literary explore, done through theoretical analysis of the thematic. At first place, a contextualization of the auditory system and its relationship with the music and the perception of sound were made, then the main theme was explored. The music, even before generate and influence motor and psychic movements in the human body, is already moving in space, because it is formed through vibrations of molecules. It is decoded first as a movement from the ears, and then decoded as sound, when in the brain. It is important to worry about sounds at high intensities and also with those which are outside the hearing thresholds within physical activities involving music, because they may be harmful to health and also to states of mind. As far as music and movement is concerned, they are closely linked, and the human being has an instinctive sense of rhythm that can be seen when listening to music, because the motor cortex is also activated. Therefore, it is important to work the sound and body movement together, because in practice they are inseparable and they contribute greatly to...

Soil tillage is one of the agricultural practices that may contribute to increase the loss of carbon through emission of CO2 (FCO2). The aim of this study was to investigate the effect of three soil tillage systems on FCO2, soil temperature and soil moisture in a sugarcane area under reform. The experimental area consisted of three tillage plots: conventional tillage (CT), conventional subsoiling (CS), and localized subsoiling (LS). FCO2, soil temperature and soil moisture were measured over a period of 17 days. FCO2 showed the highest value in CT (0.75 g CO2 m(-2) h(-1)). Soil temperature presented no significant difference (p > 0.05) between LS (26.2 degrees C) and CS (25.9 degrees C). Soil moisture was higher in LS (24%), followed by CS (21.8%) and CT (18.3%). A significant correlation (r = -0.71; p < 0.05) between FCO2 and soil temperature was observed only in CT. The conventional tillage presented a total emission (2,864.3 kg CO2 ha(-1)) higher than the emissions observed in CS (1,970.9 kg CO2 ha(-1)) and LS (1,707.7 kg CO2 ha(-1)). The conversion from CT to LS decreased soil CO2 emissions, reducing the contribution of agriculture in increasing the concentration of greenhouse gases in the atmosphere.

The goal of this paper was to determine the effects of seven diets with differents fatty acids sources in hematology of Nile tilapia before and after cold stimulus. Seven diets, with 3% of fatty acid source, were formulated: soybean oil (OS); fish oil (OP); beef tallow (SB) and mixtures of OS+OP; OS+SB; OP+SB e OS+OP+SB. Fish (112 male of Nile tilapia of 30,0 +/- 2,65g) were totally randomly distributed, with four replicates, into 28 plastic aquaria (40 L; 4 fish per aquarium). Fish were fed four times per day for 35 days. At 35th day and also after seven days cold stimulus blood was collected and the profile hematological was evaluated. Leucocytes numbers were reduced in fish fed a SB and fish oil combination diet and were highest in fish fed SB diet before cold stimulus. Plasma protein was reduced in fish fed soybean oil diets and highest in fishes fed a combination of soybean oil, fish oil and SB diets. Anything fatty acids source promotes effective changes in fish health and cold tolerance promotion. Cold don't drastically reduced fish general health status.
