Immunocompetence benefits animal fitness by combating pathogens, but also entails some costs. One of its main components is fever, which in ectotherms involves two main types of costs: energy expenditure and predation risk. Whenever those costs of fever outweigh its benefits, ectotherms are expected not to develop fever, or even to show hypothermia, reducing costs of thermoregulation and divert...

A homeothermic animal maintains a balance between its heat production and the physical processes of heat exchange with its environment by regulating its physiology and behavior. The complexity of heat transfer is beyond comprehension, but the characteristics of heat transfer for different animals in different habitats can be determined through analytical procedures. For example, evaporation los...

This study aims at performing grain scaled energy balance in mechanically-loaded aluminum polycrystal specimen. Two complementary imaging techniques were used in order to investigate the so-called material thermomechanical behavior: Digital Image Correlation and InfraRed Thermography to investigate respectively the kinematic and the thermal response of the material and, combining these two tech...

The thermal history of Earth, after the initial period of global magma ocean, is governed by the balance of surface heat loss and internal heat generation. An initially hot Earth has been gradually cooled down with time because, for most of Earth’s history, surface heat loss has been greater than internal heat supply by radiogenic isotopes. This simple energy balance places firstorder constrain...

[Purpose] This study aimed to determine the impact of aerobic exercise on aerobic capacity, balance, and treadmill time in patients with thermal burn injury. [Subjects and Methods] Burned adult patients, aged 20-40 years (n=30), from both sexes, with second degree thermal burn injuries covering 20-40% of the total body surface area (TBSA), were enrolled in this trial for 3 months. Patients were...

Energy taken up by light absorption of the leaf pigments is transformed in the process of the photosynthetic quantum conversion into photosynthesis, chlorophyll fluorescence and thermal dissipation. The mostly inverse correlation between chlorophyll fluorescence and photosynthetic activity has been extensively studied in the past, whereas only few studies dealt with the thermal dissipation. In ...

Activated carbon is known to adsorb aqueous Hg(II). MPAC (magnetic powdered activated carbon) has the potential to remove aqueous Hg to less than 0.2 μg/L while being magnetically recoverable. Magnetic recapture allows simple sorbent separation from the waste stream while an isolated waste potentially allows for mercury recycling. MPAC Hg-removal performance is verified by mercury mass balance,...

The present study compared simple thermal indices and the indices derived from energy budget models in the northwest of Iran. For this purpose, the air temperature, solar radiation, relative humidity, cloud, cover and wind speed of 13 meteorological stations in the northwest of Iran during the  the period of 1986 to 2007 were selected for comparison. The results which were extracted using Biokl...
