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...

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...

AIMS To examine the potential impact of climate variability on the transmission of Ross River virus (RRv) infection, and to assess the difference in the potential predictors of RRv incidence in coastline and inland regions, Queensland, Australia. METHODS Information on the RRv cases notified between 1985 to 1996 was obtained from the Queensland Department of Health. Climate and population dat...

Due to the relevance of the internal boundary conditions and the lack of specific data for the Scottish context, an exploration of the internal environment of traditional dwellings is needed. In this study the indoor climate of 24 properties with different levels of insulation and air-tightness was analysed using a combination of quantitative and qualitative data. Temperature and relative humid...

This paper reports a highly economical and accessible approach to generate different discrete relative humidity conditions in spatially separated wells of a modified multi-well plate for humidity assay of plant-pathogen interactions with good throughput. We demonstrated that a discrete humidity gradient could be formed within a few minutes and maintained over a period of a few days inside the d...

Objective: To evaluate the effect that seasonality has on the occurrence of respiratory symptoms in a Brazilian city with a tropical climate. Methods: This was a cross-sectional study, in which data related to subjects who sought outpatient treatment at a primary health care clinic in the city of Goiânia, Brazil, were correlated with daily meteorological data. Over a one-year period, all the pa...
