Over the last century nighttime minimum temperatures have been increasing at a faster rate than daily maximum temperatures. This warming trend has caught the attention of climatologists and agricultural scientists as they attempt to address the potential effects of elevated nighttime minimum temperatures on the health of these crops, which are so important to the U.S. economy. In this study, te...

BACKGROUND A survey was conducted of 26 physician offices and the County Health Department to determine the quality of vaccine storage. METHODS All refrigerators were examined for secure electrical supply, firmly shut door, storage of inappropriate items, and expired vaccines. A maximum-minimum thermometer was then placed in the middle of the storage area for 24 hours, and temperatures were r...

We investigate the new definition of the ordered dynamics proposed in [4]. We show that this definition leads to several properties. In particular we give necessary and sufficient conditions which indicate when a transformation preserves the dynamics of the regional maxima. We also establish a link between the dynamics, minimum spanning trees, and component trees.

This paper deals with the analysis of temperatures in a group 36 African countries. By looking at maximum, minimum and range (the difference between maximum minimum) using long memory model based on fractional integration cointegration, we first show that all series display pattern, significant positive time trend 29 countries for 33 ones. Looking range, estimated value order is smaller than on...

Rwanda has experienced high temperature rising phenomena over the last decades and hence, highly vulnerable to climate change. This paper examined spatial temporal variations of daily maximum minimum surface air (Tmin Tmax) diurnal range (DTR). It studied variables at monthly, seasonal annual time-scales from 1961 2014. The study applied various statistical methods such as ordinary least-square...
