Super-ambient temperature gas phase photocatalysis
… gas reaction was probed further as a function of temperature, where Arrhenius kinetics are applied, and as a function of reactant concentration, where Langmuir-Hinshelwood kinetics are observed.</p>

Analysis of building's response to diurnal variation in ambient temperature
… nodes necessary to understand the influence that ambient temperature has on a building's interior air temperature. The simple case of a wall of homogeneous material is modeled as an electrical system: the building walls are modeled as resistors capacitors, the ambient temperature as the sinusoidal …

The effects of ambient temperature variations on structural dynamic characteristics
… and analytical investigation of the effects of ambient temperature variations on the dynamic characteristics of a thin, square steel plate. The modal properties of the plate with two different boundary conditions and at temperatures above and below standard room temperature are examined. In …

PEO-PPO-PEO Surfactant Mixtures as Templates for Silicas With Very Large Cylindrical Mesopores at Ambient Temperature and With Helical Mesopores at Sub-Ambient Temperature
… (SBA-15) of uncommonly large pore diameter at ambient temperature. Comparable silica was synthesized with and without temperature control. Additional adjustments to experimental parameters, including reduction of the relative amount of framework precursor used in the synthesis, led to the …

Modeling Ambient Temperature Affected Photovoltaic Inverter IGBT Lifetimes With Rainflow Analysis
… of IGBTs in PV inverters. Specifically, ambient temperature, solar irradiance, and load demand for a duration of a year were considered in modeling for a chosen integrated gate bipolar transistor (IGBT) from International Rectifier. Two cases were considered in the modeling, yielding …

Survival of encapsulated probiotic bacteria during storage at low water activity at ambient temperature
… bacteria for 10 weeks of storage at 25oC (ambient temperature) at low water activities (aw). Three probiotic bacteria (Bifidobacterium animalis ssp. lactis Bb12, Bifidobacterium longum and Lactobacillus acidophilus) and one strain of most sensitive lactic acid bacteria (L. lactis ssp. …

Influence of ambient temperature on sleep, body temperature, and thermoregulation after phentolamine in rats
Item marked as restricted to the 'UIUC Users [automated]' Group (id=2) by Howard Ding (hding2@illinois.edu) on 2011-05-07T14:51:58Z Item is restricted indefinitely.

Intermediate vapor bypass: A novel design for mobile heat pump at low ambient temperature
… capacity drop was noticed at extremely low ambient temperature, mainly due to low operating pressure in the outdoor evaporator. Decreasing suction density along with dropping evaporating temperature and suction pressure led to much lower refrigerant mass flow rate with maximum compressor …

A one-step ambient temperature ferrite process for treatment of acid mine drainage waters
… unlikely. Ferrite formation at elevated temperatures (>65°C) is well established and has been successfully used in Japan to remove dissolved metals from laboratory wastes. The challenge insofar as massive volumes of AMD are concerned is to form ferrites at ambient temperatures. A second …

Effects of ambient temperature on mechanisms of pathogen transmission in house finches (Haemorhous mexicanus)
Ambient temperature is an important abiotic factor shaping the process of pathogen transmission because of its effects on hosts, pathogens, and interactions between them. However, most experimental studies demonstrating the effects of temperature on transmission remain correlative and often exclude …

The influence of spatiotemporal variation in ambient temperature on the ecology and physiology of birds
Ambient temperature has profound effects on the ecology, physiology and distribution of organisms. Ambient temperature regimes vary across spatial and temporal scales and understanding how organisms cope with this variation is a primary goal of ecological and evolutionary physiology. An emerging …

The effects of water ingestion on high intensity cycling performance in a moderate ambient temperature
… the ~1.7 l/h sweat rates, the rises in rectal temperature (~36.6° to 38.3°C) or the ratings of perceived exertion in the two trials. Ingestion of ~1.5 l of fluid produced an uncomfortable stomach fullness and reduced the distance covered in 1 h from 43.1 ± 0. 7 to 42.3 ± 0.6 km (P<0.05). Thus, …

Ambient Temperature Effects on Metabolism and Body Composition in Torpid Bats (Myotis Lucifugus and Pipistrellus Subflavus)
… factors. An inverse relationship between temperature and stable populations of M. sodalis has been observed within hibernacula. An increase in cave temperature should result in an increase in metabolic rate during torpor. Without the ability to minimize metabolic needs, irreplaceable …
