Summary: This study investigates the skin temperature in older adults at rest and after acute exercise, and assesses the influence of sex and cardiorespiratory fitness (CRF) on skin temperature. The study finds that sex has a specific effect on resting skin temperature in older adults, and there is a significant association between increases in lower limb skin temperature and CRF.

Summary: The study evaluated cattle thermal comfort in agroforestry systems, verified spatiotemporal variations of infrared temperature, and tested the potential of infrared thermography as a tool for assessing animal thermal comfort indices in agroforestry systems. Results showed that the environment inside agroforestry systems is not uniformly comfortable for cattle, with the system having the lowest shade availability accumulating the most heat. Weak to strong associations were identified between infrared variables and thermal comfort indices, demonstrating the utility of infrared thermography in assessing thermal comfort indices and onset of animal thermal stress.

Summary: In this study, three models of IRT cameras were compared for skin temperature assessment before and after exercise. The E60bx camera had slower data processing and lower perceived effort, while the C2 and FlirOne cameras underestimated temperature compared to the E60bx. It is recommended to use mean temperature for measurement and caution when using different camera models in a study.

Summary: This systematic review analyzed studies measuring skin temperature (Tsk) of individuals with spinal cord injury (SCI) during or after exercise and identified different cooling strategies. The results showed that contact thermometry and the use of ice vests and water spray are effective in reducing Tsk and decreasing the risk of heat stroke during exercise.

Summary: This study proposes a method to predict occupants' thermal state by utilizing infrared thermography, computer vision, and machine learning. By measuring the distribution of skin temperatures on specific areas of the face and hands, and using temperature differences within and between these areas, the effects of calibration drift in thermal infrared cameras are eliminated. The results show that these measurements accurately predict occupant thermal state.

Summary: Infrared thermography (IRT) can be used to assess thermal comfort inside buildings. Different IR cameras and ambient conditions impact the resolution and definition of the thermal images. There is a linear correlation between IRT results and the thermal comfort index for different facial regions. The average facial temperature can be used as an indicator for the determination of thermal comfort.

Summary: Animal flight consumes metabolic energy at a higher rate and dissipates most of it as heat. During flight, heat is dissipated through forced convection, while during rest, the head and trunk are the main areas involved in heat dissipation. The surface temperature of the legs increases with flight duration. The methodology developed in this study can be used to assess the impact of climate change on bird behavior.

Summary: The objective of this study was to evaluate the temperatures on the sole of the foot after a 10-km run using two models of socks with different weave separations. Results showed that both models of socks led to an increase in temperature, but the one with narrower weave separation had higher temperature under the first metatarsal head.

Summary: Buildings consume a large amount of energy for maintaining the thermal comfort of occupants. Real-time thermal comfort assessment is important for optimizing occupants' comfort and conserving energy. Existing studies mainly focus on assessing current thermal comfort, but in transient thermal environments, it is crucial to understand the real-time thermal sensation trend. This study investigates a novel thermal sensation index that considers the occupant's current thermal sensation trend.

Summary: Older adults, especially those with dementia, present challenges in accurately measuring thermal comfort. The Predicted Mean Vote and Adaptive Comfort methods have potential for application in older populations, but further research and improvements are needed. Long wave infrared thermography shows promise in measuring thermal sensations in older adults, but feasibility studies are required before practical deployment.

Summary: A novel method for assessing broiler pecking force data during feeding was presented in this study. The smart feeding unit prototype efficiently collected, processed, and classified signals to continuously evaluate feed intake and generate information for estimating broiler performance. The average broiler pecking force, feed intake per pecking, and pecking rate were determined with the help of the prototype.

Summary: This study tested the impact of rearing-environment enrichment on broiler movement using computer vision-based indexes. The results showed that the simultaneous application of cluster and unrest indexes could monitor broiler movement under different environmental conditions. The study highlights the importance of considering environmental complexity in future computer-vision-based monitoring and alert systems for detecting heat stress in broiler production. More research is needed to evaluate the potential positive impact of environmental enrichment in poultry production, and recalibration of the computer vision system may be necessary for large group settings.

Summary: The objective of this study was to investigate chick vocalization during social isolation and different flock sizes. The results showed that chicks emitted different sounds and expended varying amounts of energy depending on their isolation or group status and the size of the flock. The most accurate classifier to predict flock density was found to be the Random Forest model.

Summary: Brazil is a major producer and exporter of pig and broiler meat. This study aims to optimize the growth curve model parameters for pigs and broilers through the use of a hybrid metaheuristic algorithm (SAGAC). Results show that the SAGAC algorithm provides better predictive data on pig and broiler production consistency compared to previous estimations. The use of SAGAC can optimize production planning and minimize costs.

Summary: The study investigated the impact of pre-incubation ascorbic acid (AA) injection in fertile eggs incubated at high temperatures on the performance, carcass yield, and intestine morphology of broilers reared under heat stress. The results showed that egg incubation at 39 degrees C, with or without AA injection, did not improve the broilers' heat adaptation.

Summary: The study analyzed the behavioral sequences of broilers in different temperature environments, finding that under thermal stress, birds exhibited shorter behavioral sequences with more frequent lying down and eating behaviors, while under thermoneutral conditions, they showed more varied behavioral activities to ensure the welfare of the birds. The research identified temporal relationships between thermal stress and broiler behavior, underscoring the importance of further investigations into the use of temporal behavior sequences in environmental management for broilers.
