With the decline in concentrations of suspended particulate pollution in Greater London the association seen in the 1950s and early 1960s between daily mortality and air pollution in the conurbation is no longer apparent. Associations between unusually cold weather and short-term increases in mortality have been noted; there appears to be a tendency for influenza epidemics to follow cold spells.

in this paper the changes in the heat capacity of cooling towers has been investigated as a result of injecting combustion products of boilers. in the tower, the air is re-heated through mixing with hot flue gas after passing through the heat exchangers. as a result of this process, the draft of the cooling tower is increased. the additional produced draft depends on the ambient temperature and...

The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with different values of yield stress and plastic viscosity were tested in a concrete truck. The measurements made with the truck were based on the ty...

BACKGROUND Chilblains are quite often seen in various parts, in particular cold weather areas of Pakistan. Unfortunately, no studies have so far been carried out in Pakistan, to determine epidemiological aspects of chilblains. The objective of this study was to see the epidemiological patterns of chilblains at a moderately cold weather station. METHODS The study was conducted at Dermatology o...

The paper presents the brief information on particular results of experimental study focused to the problems of behavior of structural plated components made of fiber-cement-based materials and used in building constructions, exposed to atmospheric physical effects given by the weather changes in the summer period. Weather changes represented namely by temperature and rain cause also the change...

PURPOSE To examine seasonal variations in urinary symptoms in Korean men with lower urinary tract symptoms and benign prostatic hyperplasia (LUTS/BPH). MATERIALS AND METHODS Records were obtained from a consecutive database of LUTS/BPH patients from March 2010 to February 2014. A total of 1,185 patients were suitable for analysis. The International Prostate Symptom Score (IPSS), uroflowmetric...

BACKGROUND Projected increases in weather variability due to climate change will have severe consequences on human health, increasing mortality, and disease rates. Among these, cardiovascular diseases (CVD), highly prevalent among the elderly, have been shown to be sensitive to extreme temperatures and heat waves. OBJECTIVES This study aimed to find out the relationship between daily temperat...

In some occupations it is hard to protect the hands against the severe weather conditions in wintertime due to the requirement to maintain manual dexterity. Decrease in temperature of the hands increases risk of cold injury and deteriorates muscle function and manual dexterity, which in turn decreases productivity. A series of field and lab studies were performed to investigate cold stress and ...
