Background and purpose: Bottled water is widely packaged and distributed in PolyethyleneTerphthalate (PET) bottles with plastic caps. Plastic materials in bottles, and other additives such as heavy metals, can leak into water during manufacturing or storage process in different ambient conditions. The main objective of this study was to investigate the effect of sunlight and environmental tempe...
Flowering is the primary trait affected by ambient temperature changes. Plant microRNAs (miRNAs) are small non-coding RNAs playing an important regulatory role in plant development. In this study, to elucidate the mechanism of flowering-time regulation by small RNAs, we identified six ambient temperature-responsive miRNAs (miR156, miR163, miR169, miR172, miR398 and miR399) in Arabidopsis via mi...
phospho sulfonic acid (psa) synthesized as an environmentally safe and efficient solid acid catalyst, and it used for the synthesis of several 2-disubstituted benzimidazoles, 2-substituted benzoxazoles, and 2-substituted quinoxalines in ethanol as a green solvent at ambient temperature is described. (i) a very simple, green and efficient procedure for the synthesis of benzimidazole and also benz...
Background: The objective of this studywas to investigate the effect of high and moderate summer ambient temperatures on testicular structures and endocrine profile of developing ram lambs. Materials and Methods: Twenty fall-born ramlambswere randomly divided into two groups: animalswere kept outdoor (n = 10) under ambient temperature (31-50°C) or maintained indoor (26-32°C) from May to October...
We have examined the interaction of photoperiod and temperature in regulating the parr-smolt transformation and its endocrine control. Atlantic salmon juveniles were reared at a constant temperature of 10 degrees C or ambient temperature (2 degrees C from January to April followed by seasonal increase) under simulated natural day length. At 10 degrees C, an increase in day length [16 h of light...

Dried blood spots (DBS) are an alternative specimen type for HIV drug resistance genotyping in resource-limited settings. Data relating to the impact of DBS storage and shipment conditions on genotyping efficiency under field conditions are limited. We compared the genotyping efficiencies and resistance profiles of DBS stored and shipped at different temperatures to those of plasma specimens co...
The combination of emulsified diesel and low temperature combustion (LTC) technology has great potential in reducing engine emissions. A visualization study on the spray and combustion characteristics of water emulsified diesel was conducted experimentally in a constant volume chamber under conventional and LTC conditions. The effects of ambient temperature on the evaporation, ignition and comb...
SHUM, A., G. E. JOZ-INSON, AND K. V. FLATTERY. rnfruenca of ambient temperature on excretion of catecholamines and matab elites. Am, J. Physiol. 216(5) : 1164-1169. 1969.-The study demonstrates the influence of ambient temperature on the excretion of epinephrine, norepinephrine, and their major metabolites. As a result of this work it is concluded that norepinephrine secretion increases in a co...
