from december 1990 to june 1992 in ahwaz, capital of khoozestan province, 1333 patients referred to khoozestan parasitology center, in 29 cases of whom cryptosporidium pallium was detected. all infected patients were less than eight years of age. the parasite was most prevalent in the 0-1 year old age group. though some c. parvlil1l infected cases harboured giardia lamblia, there was no relatio...

To accurately calculate heat, air and moisture (HAM) transfer in building envelopes, appropriate boundary conditions need to be specified. A previous study by Salonvaara and Karagiozis showed that calculations of moisture content in brick cladding could differ up to thirty times in magnitude when using different weather data sources. This study aims to investigate the effect of using urban (dow...

BACKGROUND AND OBJECTIVES Changes in relative humidity, along with other meteorological factors, accompany ongoing climate change and play a significant role in weather-related health outcomes, particularly among children. The purpose of this review is to improve our understanding of the relationship between ambient humidity and child health, and to propose directions for future research. MET...

BACKGROUND Temperature and humidity have been reported to influence the results of whole blood glucose (WBG) measurements. METHODS To determine whether patient WBG values were affected by seasonal variation, we conducted a retrospective analysis of 3 years' worth of weekly averages of patient WBG in five Edmonton hospitals. RESULTS In all five hospitals, the winter WBG averages were consist...

Weather variations have clear associations with the epidemiology of dengue fever and populations of Aedes aegypti mosquitoes. Data on humidity associations, however, lags with respect to its effect on host-biting, nectar-seeking and survival. This experimental study on Ae. aegypti, sourced from the arid tropics, investigated the effect of low and high relative humidity and diet in relation to h...

BACKGROUND/AIM To investigate the seasonal variations of the incidence of renal colic by a computerized analysis of cyclic climatic features. METHODS 1,163 consecutive patients with acute renal colic were studied. Eigendecomposition and signal reconstruction of district temperature and humidity were performed to establish any cyclic variation. Average temperatures and humidity values were cal...

Legionnaires' disease (LD) is an acute form of pneumonia, and changing weather is considered a plausible risk factor. Yet, the relationship between weather and LD has rarely been investigated, especially using long-term daily data. In this study, daily data was used to evaluate the impacts of precipitation, temperature, and relative humidity on LD occurrence in Taiwan from 1995-2011. A time-str...

The creation of small and cheap sensors promoted the emergence of large scale sensor networks. Sensor networks allow monitoring a variety of physical phenomena, like weather conditions (temperature, humidity, atmospheric pressure ...), traffic levels on highways or rooms occupancy in public buildings. Some of the sensors produce large volume of data such as weather temperature. These data shoul...

The use of evolutionary algorithms for calculation of the optimal control of the states of a greenhouse system will be presented. The integrated model employed (greenhouse climate, crop growth, outside weather conditions and control equipment) predicts temperature, air humidity and CO2 concentration in a time interval of 15-60 minutes (short time-scale model). The paper presents the optimizatio...
