This thesis focuses on creating an application software for monitoring and analyzing changes in body surface temperature before and after exercise test by the means of contactless thermography. Initial, theoretical part of this thesis talks about principles and possible scenarios, in which one could employ infrared thermography followed by physiology of the exercise load and concludes with an observation of the changes in body surface temperature while focusing on the actions that take place during the exercise test. Practical part of the thesis comprises of the exercise test and building of the application software for the analysis of the acquired thermographic visual output. The application software offers 2 kinds of analyses: general and under-load, while it aims to provide evaluation in both cases based on user-selected areas of interest. Last chapter of this thesis includes final output with commentary and eventual usage of the under-load experiment and application software in practical use.

Title: Observing of the skeletal muscle shape changes depending on human body surface temperature Objectives: The aim of this work is to observe the cross-section changes of the m. rectus femoris depending on human body surface temperature changes. The cross section of the muscle was characterized by two dimensions: VDDM (ventrodorsal dimension of muscle) and LMDM (lateromedial dimension of muscle). The body temperature was affected by local positive and negative thermotherapy methods. Methods: The first part of the experiment focused on the selection of appropriate local positive and negative thermotherapy forms. Four of them were selected (two positive thermotherapy methods - Peat thermotherapy bags and infrared heater InfraPhil HP3616 and two negative thermotherapy methods - gel bag Cryoflex and Cryogen 3 device) for the main research. Twelve subjects participated on the main experiment. Selected local positive thermotherapy methods were applied on the centre of the subject's thighs, subsequently selected negative thermotherapy methods were applied. The body surface temperature was measured immediately before application, after 30 minutes of positive thermotherapy and after subsequent negative thermotherapy application. Ultrasound images of m. rectus femoris were taken at same time. VDDM and...

No. of bitstreams: 1 MicheleDFC_DISSERT.pdf: 920263 bytes, checksum: 53a2a3e4da4623de921e854a9507225d (MD5) Previous issue date: 2009-08-13 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Honeybees managed in semi-arid region were observed with the objective to determine the individual body surface temperature in different places, as well the heat loss by convection. The body surface temperature was measured with micro thermocouple type T touching in three different body region (the head, thorax and abdomen), its collected from four different places (beehive, hive entrance, foraging and watering place) in which they was arrested by the wings between thumb and forefinger for a few seconds, without causing any injury to the animal. The same time was made measurements of climatic variables. The convective heat transfer was estimated by the theory of convection from a horizontal cylinder. The results showed that had different among temperature surface in parts of the body and in different places. The thorax showed the hottest part of the body, then the head and abdomen was the coldest. In hive entrance the bee had the highest thorax temperature (36.6°C) due the shivering caused for flight muscles. Already, in watering place the surface temperature was the lowest in all parts of the body probably because almost always the body surface had wet by water, if not, at the time of measuring the bee regurgitated the liquid ingest in your body. When the bee was in beehive and in hive entrance (in conditions of low wind) the heat loss by convection increases from 0 to 7.5 W m-2 while increase in the gradient temperature from 0 to 10ºC, but when the wind was 1.0 ms-1 the heat loss by convection increases from 0 to 27.5 W cm-2. In bee hive when the black globe showed a temperature of 43°C, the body surface temperature of bee was 46°C, but when the black globe temperature increased 6°C, the body surface temperature lowered 3°C. These results clearly explain that the bee in a semi-arid region in individual or society has physiological and behavioral mechanisms to regulate their body temperature, but more studies are requires know the most efficient thermoregulatory processes. And climatic variations of the environment are crucially to their thermoregulatory behavior / Abelhas criadas em uma região semi-árida foram observadas com o objetivo de determinar qual a temperatura da superfície corpórea do individuo em diferentes lugares, além da sua perda de calor por convecção. A temperatura da superfície corporal foi medida com micro-termopar tipo T tocando em três diferentes regiões do corpo (cabeça, tórax e abdome) da abelha, sendo estas coletadas em quatro diferentes lugares: dentro da colméia, no alvado, forrageando e no bebedouro. Para a medição da temperatura da superfície corpórea, as abelhas tinham as asas presas pelo dedo polegar e indicador por alguns segundos e logo após eram soltas, sem causar nenhuma injúria ao animal. Ao mesmo tempo era feitas as medições das variáveis climáticas. A transferência de calor por convecção foi estimada aplicando-se a teoria da convecção em cilindros horizontais. Os resultados mostraram que houve diferença de temperatura de superfície entre as partes do corpo e nos diferentes lugares. O tórax apresentou a parte mais quente do corpo, seguido da cabeça e abdômen. A abelha no alvado apresentou a maior temperatura de superfície do tórax (36,6°C). Já, no bebedouro a temperatura de superfície foi a mais baixa em todas as partes do corpo. Provavelmente por apresentarem quase sempre a superfície do corpo molhada, se não, na hora da medição a abelha regurgitava a água ingerida no seu próprio corpo. Quando a abelha se encontrava dentro da colméia e no alvado a perda de calor por convecção aumentou de 0 a 7,5 W m-2 com o aumento no gradiente de temperatura de 0 a 10ºC, mas quando o vento foi de 1,0 m s-1 a perda de calor por convecção aumentou de 0 a 27,5 W m-2. Quando a abelha estava no interior da colméia e o globo negro apresentou uma temperatura de 43°C, a temperatura de superfície corpórea desta foi de 46°C, mas quando a temperatura de globo negro aumentou 6°C, a temperatura de superfície corporal da abelha baixou 3°C. Estes resultados explicam claramente que as abelhas em uma região semi-árida como indivíduo ou em colônia possuem mecanismos fisiológicos e comportamentais para regular sua temperatura corporal. E que as variações climáticas do meio ambiente são determinantes para o seu comportamento termorregulatório / 2017-05-16
