Summary: In this study, a sensor was developed to measure the heat capacity of the skin. The sensor consists of a thermopile equipped with a programmable thermostat and can measure the heat capacity on a 4 cm(2) skin area. The heat capacity of the skin varies in different regions and is mainly determined by the water content of the tissue.

Summary: European anchovy and sardine are crucial for the marine ecosystem in the Northwestern Mediterranean Sea, but concerns over their stock status are rising. Fatmeter measurements are strongly correlated with calorimetry ED for sardine, providing a faster and suitable method to evaluate the energy content of both species.

Summary: This study improves the calibration process of a calorimetric sensor for medical application through the use of localized constants models and suitable experiments. A new method of operation is proposed that allows measurement to be performed with the sensor applied on the skin. The operation and calculation methods were validated by simulations, leading to successful measurement of heat capacity and equivalent thermal resistance in the human body.

Summary: A novel dual-condenser heat pipe PV/T system is proposed and the heat transfer limit mathematical model is established. The effects of operating temperature, evaporator inclination, evaporator size, and height difference on the system are analyzed. The experimental results show that as the temperature increases, the system's heat transfer limits in heating and hot water modes increase significantly, while the boiling limit, capillary limit, and sonic limit are influenced by other factors.

Summary: The purpose of this study was to evaluate regional differences in cutaneous warmth and hotness thresholds in response to radiant heat exposure. Measurements were taken on 17 body regions, and it was found that the forehead, lower back, and palm had the highest warmth thresholds, while the foot and sole had the lowest values. It was also observed that thermal thresholds from radiant heat exposure were lower than those from conductive heat exposure.

Summary: This paper outlines the development of a finite element human thermoregulatory model using an anatomically and geometrically correct human body model. The model simulates thermal responses through a passive and active system, providing insight into human thermoregulatory responses to non-uniform and transient environments. Comprehensive validation shows predictions are accurate and acceptable, with comparisons of predicted temperatures at 29 sites with measured values in comfort, hot, and cold conditions.

Summary: Heat stress and its induced heat strain cause significant economic losses in the dairy industry each year. Advances in sensor and wireless transmission technologies have enabled the automatic measurement of body surface temperature and respiration rate in dairy cows, allowing for early detection of heat strain. Efforts are being made to develop meaningful thresholds for early detection based on physiological and environmental indicators, with a focus on the customization of thresholds according to influencing factors for increased precision.

Summary: Metabolic rate is crucial for human thermal comfort, and it varies between children, adolescents, and adults, influenced by age and gender. Males generally have higher metabolic rates, which increase with age and activity levels. Standards should incorporate specific metabolic data for children and adolescents to optimize thermal environment design in schools.

Summary: This study determined the energy contents of hybrid rye fed to growing pigs, and investigated the effects of particle size on energy values. Results showed that finely ground hybrid rye had higher digestible energy and metabolizable energy compared to coarsely ground hybrid rye, while net energy only showed a slight improvement.

Summary: This study investigates the thermal probing depth of a skin calorimeter to measure the heat capacity and thermal resistance of a 4 cm2 skin region. The results show that the thermal penetration depth is mainly determined by the period of the thermal excitation. Measurements on the left wrist of a healthy 64-year-old male subject indicate that the heat capacity in both the dorsal and volar zones is of the same order of magnitude, with an initial value of 4 J/K and exponential increase up to 7 J/K over time. The thermal resistance also increases exponentially with time, ranging from 27 to 36 K/W for the volar zone and 32 to 45 K/W for the dorsal zone.

Summary: This study focuses on synthesizing silica encapsulated paraffin phase change materials (PCMs) and their applications in cement-based systems. The paraffin droplets are successfully encapsulated into nano-sized capsules through one-pot in-situ hydrolysis and subsequent polycondensation. The resulting nanoencapsulated PCMs (NEPCMs) have distinct core-shell structures and spherical geometry. The NEPCMs show high encapsulation ratio and efficiency, as well as excellent latent heats of melting and solidification. The findings demonstrate that the addition of NEPCMs to cement can reduce the temperature rise during the heat of hydration, making them reliable high thermal energy storage materials for concrete and building materials.
