BACKGROUND In the early stages of Pandemic (H1N1) 2009, border control measures were taken by quarantine stations to block the entry of infected individuals into Japan and community containment measures were implemented to prevent the spreading. The objectives of this study were to describe these measures and the characteristics of infected individuals, and to assess the measures' effectiveness...

background: forecasting of air pollutants has become a popular topic of environmental research today. for this purpose, the artificial neural network (aan) technique is widely used as a reliable method for forecasting air pollutants in urban areas. on the other hand, the evolutionary polynomial regression (epr) model has recently been used as a forecasting tool in some environmental issues. in ...

one of the major issues of increasing agricultural production, is adaptation of technology to specific climatic variables in cultivated areas. knowing the weather and climatic condition and periodic yearly and multi-year changes of meteorological phenomena and deviations from normal values ​​are of major requirements of modern agriculture. in this study, daily, monthly and annual weather data o...

simultaneous heat and water model (shaw) is based on the assimilation rate of melting and/or freezing of the accumulated snow as well as melting of ice in soil. the main objective of this study was to evaluate applicability of shaw model in determining maximum depth of frost penetration in soils in some typical climates of iran. to this end, the daily data of air temperature, soil temperatures ...

An Analysis of Covariance (ANCOVA) was used to derive the influence of the meteorological variability on the daily maximum ozone concentrations at 12 low-elevation sites north of the Alps in Switzerland during the four seasons in the 1992–2002 period. The afternoon temperature and the morning global radiation were the variables that accounted for most of the meteorological variability in summer...

In thee meteorological observation points were installed identical weather stations and a network infrastructure were created to receive and record the environmental parameters at every minute. A series of six out of forty-four parameters relating air, and solar radiation were taken into the analysis. The inference between observed data in three different locations was analyzed in order to find...

GPS observables taken from light-weight GPS buoys more than 80 km from the GPS reference stations have been analysed using different noise models in the parameter estimation process. The time series solution of the GPS buoy positioning have been used to extract values of oceanic variables (sea level, tides and waves) and tropospheric information. These variables are compared with data from mode...

In previous work a model was developed to predict the annual average cumulative distribution of the effective earth radius factor, the k-factor, for telecommunications applications in South Africa. Long term meteorological radiosonde data from eight stations were used for this purpose. In this paper, the model is used to predict the cumulative effective earth radius, or k-factor, distribution f...
