Previous animal models of heat stress have been compromised by methodologies, such as restraint and anesthesia, that have confounded our understanding of the core temperature (T(c)) responses elicited by heat stress. Using biotelemetry, we developed a heat stress model to examine T(c) responses in conscious, unrestrained C57BL/6J male mice. Before heat stress, mice were acclimated for >4 wk to ...

BACKGROUND The electron transport chain, Rubisco and stomatal conductance are important in photosynthesis. Little is known about their combined responses to heat treatment at different temperatures and following recovery in grapevines (Vitis spp.) which are often grown in climates with high temperatures. METHODOLOGY/FINDINGS The electron transport function of photosystem II, the activation st...

GIBBS, C. L., AND W. R. GIBSON. Energy production of t-at soleus muscle. Am. J. Physiol. 223(4): 864-871. 1972.-A thermopile was used to record the heat production of rat soleus muscles, weighing between 16 and 96 mg, at 27 C. The muscles were subjected to isotonic and isometric tetani, 2 set in duration, and the stimulus frequency was 30 Hz. As well as recording initial energy production, reco...

Expander who drives a electromotor to generate electricity is the core of low-temperature waste heat recovery equipment. At present, domestic expanders on waste heat recovery system mostly come from exploration, research and improvement on the existing models of screw expanders and scroll expanders, which has complex structures and high costs. Against the shortcomings above, we researched and d...

Predicted global climate change threatens the distributional ranges of species worldwide. We identified genes expressed in the intertidal seagrass Zostera noltii during recovery from a simulated low tide heat-shock exposure. Five Expressed Sequence Tag (EST) libraries were compared, corresponding to four recovery times following sub-lethal temperature stress, and a non-stressed control. We sequ...

This work considers improving the heat recovery of an existing heat exchanger network (HEN) while minimizing the total annualized cost of the retrofit design. The focus is on stepwise approaches that generate, starting from the base case network, a candidate retrofit HEN at each step in order to sequentially retrofit the HEN topology while permitting user intervention during the resolution proc...

We used a canine model of airway reactivity to examine the role of airway heat flux in the response to dry air challenge. Airflow-induced bronchospasm (AIB) was assessed by measuring collateral system resistance (Rcs) with a wedged bronchoscope technique in anaesthetized mechanically ventilated dogs. We manipulate post-challenge airway heat flux by exposing peripheral airways to cool dry air (2...

Residential domestic hot water (DHW) energy consumption represented 16% of the EU household heating demand in 2013. Due to the improvement of the building envelop, it is expected to increase significantly, with values between 20% to 32% in single family buildings, and between 35% to almost 50% in multifamily buildings. Currently, this energy is lost to the environment after its use, but it can ...

Heat stroke (HS) is a serious civilian and military health issue. Due to the limited amount of experimental data available in humans, this study was conducted on a mouse mathematical model fitted on experimental data collected from mice under HS conditions, with the assumption there is good agreement among mammals. Core temperature (T(c)) recovery responses in a mouse model consist of hypotherm...

This study investigated (1) the susceptibility of Bacillus anthracis (Ames strain), Bacillus subtilis (ATCC 19659), and Clostridium sporogenes (ATCC 3584) spores to commercially available peracetic acid (PAA)- and glutaraldehyde (GA)-based disinfectants, (2) the effects that heat-shocking spores after treatment with these disinfectants has on spore recovery, and (3) the timing of heat-shocking ...
