Introduction: The issue of the influence external factors such as meteorological conditions on dynamics coronavirus pandemic is extremely relevant, since understanding physical foundations any process helps predict its results in specific and, to a certain extent, manage it. Objective: In order assess effect relative humidity incidence COVID-19, we analyzed opinions international scientific com...

one of the most main head in governments is to achieve the energy for their countries. as the fossil sources are at their ends and also they cause greenhouse emission and environment pollution, shifting to renewable sources of energy is an indispensable alternative for most countries. the sun is the most important renewable energy source. to assessment reachable solar radiation in mashhad from ...

Environmental irritants are important risk factors for skin diseases, but little is known about the influence of environmental factors on eczema incidence. In this time-series study, our objective was to examine the associations of environmental factors with outpatient visits for eczema. Daily outpatient visits between 2007 and 2011 (1826 days) were collected from Huashan Hospital in Shanghai, ...

The aim of this study was to determine the independent effects of climatic factors: rainfall, temperature and relative humidity, on the occurrence of dengue hemorrhagic fever (DHF) in Thailand after adjustment for cyclical pattern. Data regarding monthly DHF reported cases by province, monthly rainfall, rain-days, average daily maximum temperature, average daily minimum temperature and average ...

The investigation into airborne fungal spore concentrations was conducted in Szczecin (Poland) between 2004 and 2009. The objective of the studies was to determine a seasonal variation in concentrations of amerospores on the basis of meteorological parameters. The presence of spores in Szczecin was recorded using a volumetric method. Fungal spores were present in the air in high numbers in late...

In present world, inequality and uncertainty is high in section of agriculture production and food security of a great amount of people in developing countries is not supplied. Based on studies of international organizations, about a third of produced food for human consumption in worldwide is lost or wasted. While in developing countries, there is price enhancement, decrease in access to healt...

The paper deals with the relationship betweeen the water content of washed Serratia marcescens and the thermodynamic activity of water, a,, over the range 0 < a, < 1.0. Two overlapping types of measurement are used: osmotic water exchange and water-vapour sorption. The data are given in terms of the equation w = Bm-' where w is water content, m is external osmolality (actual or effective, depen...

Wall constructions have the capacity to contribute passive regulation of indoor Relative Humidity. This property, referred as moisture buffering, is linked hygroscopicity materials, which allows materials store and release from surrounding air, depending on Humidity levels. Laboratory testing procedures, based a step-response method, were introduced quantify buffering. The step response method ...
