1. Thermal preferences and limits of Triatoma brasiliensis in its natural environment - Field observations while host searching
The goal of this work was to explore the thermal relationship between foraging Triatoma brasiliensis and its natural habitat during the hottest season in the state of Ceará, Brazil. The thermal profiles were determined using infrared analysis. Although the daily temperature of rock surfaces varied in a wide range, T. brasiliensisselected to walk through are

2. Ritmo circadiano de temperatura corporal no tuco-tuco (Ctenomys aff. knighti), um roedor subterrâneo sul-americano / Circadian rhythm of body temperature in the tuco-tuco (Ctenomys aff. knighti), a South-American subterranean rodent
Em mamíferos, a temperatura corporal (Tc) varia ao longo do dia, de forma rítmica, bem como a atividade locomotora. Essa ritmicidade diária é gerada endogenamente, por osciladores circadianos. Em geral, os valores mais elevados de Tc concentram-se nos mesmos horários em que há atividade locomotora. No entanto, variações diárias de Tc são observadas

3. Avaliação comportamental e fisiológica de suínos em baias individuais e gaiolas metabólicas. / Behavioral and physiological evaluation of swine in individual stalls and metabolic cages.
Two articles were made to assessed the behavioral and physiological parameters of pigs housed in individual stalls and metabolism cages. The first article was to evaluate the effects of period (before and during), type of housing (individual stall and metabolic cage) and feeding treatment (T1, T2, T3 and T4) in salivary cortisol concentrations. Was collected

4. Caracterização do perfil do ciclo sono-vigília em ratos sob dessincronização forçada / Characterization of sleep-wake cycle profile in rats under forced desynchronization
O comportamento circadiano associado ao ciclo diário de 24 horas deve-se à ação de um relógio circadiano que em mamíferos se localiza nos núcleos supraquiasmáticos do hipotálamo (NSQs). Sob condições experimentais em que ratos são submetidos a um ciclo claro-escuro (CE) simétrico de 22h (T22) as regiões ventrolateral (vl) e dorsomedial (dm) dos

5. Estudo da variabilidade circadiana da temperatura corporal e ciclo vigília-sono do estudante trabalhador noturno / Study of circadian variability of body temperature and sleep-wake cycle student night shift worker
Introdução: Devido à crescente industrialização da sociedade, torna-se cada vez mais comum o trabalho em turnos, bem como o desenvolvimento do trabalho noturno, porém com pronunciado efeito negativo no sono, desempenho e saúde. Objetivo: Investigar os padrões do ciclo vigília-sono e a ritmicidade circadiana da temperatura corporal periférica, atrav

6. A luz alem da visão : iluminação e sua relação com a saude e bem-estar de funcionarias de lojas de rua e de shopping centers em Porto Alegre / The light beyond vision : lighting and its relationship with health and well-being of employees at street and shopping mall retail stores in Porto Alegre
This work addresses the issue of non-visual impacts of human exposure to light, in an attempt to relate the quality of lighting to health, comfort, and well-being of female retail store employees. The sample for the cross-sectional study was randomly established with female volunteers. Three groups were selected: street retail stores with outside contact and

7. Ocorrência de fogachos e sua relação com os ritmos circadianos de temperatura periférica do punho, atividade/repouso e estados de humor em mulheres na pós-menopausa. / Hot flashes episodes and the circadian rhythms of wrist temperature, rest/activity and mood in post-menopausal women.
In this study we evaluated possible correlations between peripheral (wrist) temperature, rest/activity and mood circadian rhythms and the occurrence of hot flashes in post-menopausal women. Nineteen patients from Hospital das Clínicas de São Paulo had participated this study. The patients were separated in 2 groups: post-menopausal women with hot flashes (

8. Temporal organization in Pyrrhura lepida lepida / Organização temporal em Pyrrhura lepida lepida
The behaviours of many animals are organized in the rhythmic pattern as mechanism of the adaptation in a cyclical environment. The goal of this research was describe the daily distribution of the behaviors in Pyrrhura lepida lepida, to characterize your temporal organization. It was observed, individually, the behaviour of four birds that are living at the Z

9. Assistência clínica materna e neonatal às diferentes condições obstétricas em bovinos da raça Holandesa / Maternal and neonatal clinical assistance under distinct obstetrical conditions in Holstein cattle
The novel reproductive biotechnologies (ET, IVF and Cloning) require more accurate control of pregnancy and parturition, due to obstetrical problems as a result of the large offspring syndrome or reduced calf vitality associated with placental anomalies. Hence, the reduction in neonatal mortality is justifiable as research in this area progresses, aiming mat

10. Ritmo biolÃgico da temperatura corporal em preguiÃas (Bradypus variegatus)
Sloths are heterothermal mammals showing a mean Body Temperature (BT) of around 33ÂC, and behavioral responses possibly related with the light-dark cycle (LD) and ambient temperature. Reports on studies regarding BT rhythmicity during the 24h period are inconclusive. The aim of the present study was to characterize the biological rhythm of BT in Bradypus va

11. "Estudo da ocorrência de acidentes entre trabalhadores de uma indústria frigorífica do Estado de São Paulo" / "A study on the occurrence of accidents among workers at a meat packing industry in the State of São Paulo"
Meat packing work is marked by repetitive activities; intense work rhythm; environments with inadequate levels of illumination, noise and temperature; presence of dust; small spaces and frequent handling of cutting instruments. These characteristics make this activity exhausting and dangerous and, hence, an interesting object of study, but is socially releva

12. Circadian rhythms of body temperature in shift-workers at a coalface
Colquhoun, W. P., and Edwards, R. S. (1970).Brit. J. industr. Med.,27, 266-272. Circadian rhythms of body temperature in shift-workers at a coalface. The oral temperatures of a group of coalface workers were recorded daily at intervals during their period of work underground, over a three-week cycle of day, afternoon and night shifts. The basic mean circadia
