Background: The role of temperature changes, as an environmental risk factor, in the human health status has been investigated in recent studies. Accordingly, the present two-year study was conducted to evaluate the incidence of myocardial infarction (MI) in warm and cold seasons in Ali-ibn Abi Talib Hospital, Rafsanjan, Iran. Materials and Methods: In this descriptive and cross-sectional st...

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.

Habitual physical activity is an important determinant of health, yet many people are considered to be inactive. Identification of the obstacles to greater participation is necessary for the development of strategies to overcome those obstacles. The weather has been identified as a perceived barrier to participation in physical activity, but exactly which adverse weather conditions are most imp...

Extensive literature is available on the development of an economic approach to value weather data and analysis of the cost-benefit characteristics of alternative meteorological data acquisition systems. However, to determine the economic value of a specific set of meteorological data is still a very complex task. Because the data is used in wide variety of weather forecasting processes, which ...

INTRODUCTION Provision for the safety and health care of persons attending mass-gathering events presents unique challenges to organizers. This study was designed to determine the factors that contribute to patients seeking medical care during these events. METHODS We performed a retrospective review of patient care records for visits that occurred during race weekends at the Kansas Speedway ...

[1] Atmospheric phase delays are considered to be one of the main performance limitations for high-quality satellite radar techniques, especially when applied to ground deformation monitoring. Numerical weather prediction (NWP) models are widely seen as a promising tool for the mitigation of atmospheric delays as they can provide knowledge of the atmospheric conditions at the time of Synthetic ...

The local abundance of Culex mosquitoes is a central factor adding to the risk of West Nile virus transmission, and vector abundance data influence public health decisions. This study evaluated differences in abundance estimates from mosquitoes trapped using two common methods: CO2-baited CDC light traps and infusion-baited gravid traps in suburban, Chicago, Illinois. On a weekly basis, the two...

In China, 260 million people migrate to cities to realize their urban dreams. Despite that these migrants play an important role in the rapid urbanization process, many of them fail to settle down and eventually leave the city. The integration process of migrants thus raises an important issue for scholars and policymakers. In this paper, we use Shanghai as an example to investigate migrants’ b...

Atmospheric water vapour (AWV) plays an important role in the pursuit of weather research, in particular extreme weather phenomena. Conventional atmospheric sounding methods including radiosonde and water vapour radiometer (WVR)) have the disadvantages of low spatial or temporal resolutions or high cost. As an emerging remote sensing approach of AWV, GPS is an ideal complement due to its unique...
