We show the annual climatology of the diurnal cycle, stratified by opaque cloud, using the full hourly resolution of the Canadian Prairie data. The opaque cloud field itself has distinct cold and warm season diurnal climatologies; with a near-sunrise peak of cloud in the cold season and an early afternoon peak in the warm season. There are two primary climate states on the Canadian Prairies, se...

Our aim is to provide an observational reference for the evaluation of the surface and boundary layer parameterizations used in large-scale models using the remarkable long-term Canadian Prairie hourly dataset. First we use shortwave and longwave data from the Baseline Surface Radiation Network (BSRN) station at Bratt’s Lake, Saskatchewan, and clear sky radiative fluxes from ERA-Interim, to sho...

Carleton (1) established that high temperature has caused 59,300 suicides during 1987–2013 in India and for temperatures above 20 °C, a 1 °C increase in a single day’s temperature causes ∼70 suicides in the country. The author argues that high temperature stimulates suicides through a crop-damaging agricultural channel as the temperature deviations above the 20 °C threshold in growing season ar...

Oviposition is a major event in the life history of mosquitoes, shaping both individual fitness and vectorial capacity. Several exogenous factors have been shown as important for the dynamic forcing of oviposition at finely (hourly) and coarsely (monthly or season to season) grained temporal scales. However, field studies addressing the interplay of weather factors on oviposition dynamics at th...

background: benzene is one of the most widely used volatile organic compounds showing severely adverse effects on human health. removing benzene from the airflow or controlling its amounts, is one of the issues put to discussion in the field of environmental engineering. the objective of this study was to examine the efficacy of the ultraviolet-c (uv-c) radiations on removing benzene from the a...

To assess the ability of the nose to warm and humidify inhaled air, we developed a nasopharyngeal probe and measured the temperature and humidity of air exiting the nasal cavity. We delivered cold, dry air (19-1 degrees C, <10% relative humidity) or hot, humid air (37 degrees C, >90% relative humidity) to the nose via a nasal mask at flow rates of 5, 10, and 20 l/min. We used a water gradient a...

OBJECTIVE To investigate the effects of fine particulate matter emitted through biomass burning on hospitalizations for respiratory diseases in children living in Manaus, Northern Brazil. METHODS Descriptive study with ecologic time series design carried out in Manaus from 2002 to 2009. Hospital admission data were obtained from the Unified Health System database. PM2.5 levels were estimated ...

The present experiment was performed with the aim of investigating the effect of season on behavioral activities of donkeys during the rainy and harmattan seasons in the Northern Guinea zone of Nigeria. Sixteen apparently healthy donkeys were used as subjects and divided into four groups based on age. During each season, behavioral activities of each donkey were evaluated for three weeks using ...

HIMMELFARB, PHILIP (University of Massachusetts, Amherst), HAMED M. EL-BISI, R. B. READ, JR., AND WARREN LITSKY. Effect of relative humidity on the bactericidal activity of propylene oxide vapor. Appl. Microbiol. 10:431-435. 1962.-Because of the low toxicity of its breakdown product, propylene oxide (PO) vapor will play an increasingly important role in the preservation of foods. It is therefor...

In a previous paper Hey and Maurice (1968) have reported the effect of changes of relative humidity on the heat production and heat loss in normal naked babies in a specially constructed metabolic chamber under controlled environmental conditions. In order to evaluate the clinical relevance of these observations we have studied the control of relative humidity that could be achieved in three co...
