Drought is the most widespread climatic extreme that has negative impacts on ecohydrology. Studies have shown drought can cause certain degrees of disturbances to different ecohydrological variables, but duration and severity thresholds are sufficient changes in variables remain largely unknown. At same time, we should not ignore dynamic variation drought’s effect under condition climate change...

Analysis of trend in hydro-meteorological variables is extremely important for improving water resources planning and management. This study examines monthly rainfall temperature using the recently developed Innovative Trend Method (ITAM) Mann-Kendall (M-K) with Sen’s slope test. Record precipitation data was obtained from International Institute Tropical Agriculture (IITA) Ibadan, Nigeria peri...

The aim of the study was to determine functional relationships between composition of air spora and meteorological factors, using multivariate statistical technique: canonical correspondence analysis (CCA). Analyses were conducted for the data collected during the 4 year (2007-2010) and, in order to show the dynamics of such relationships, for each year separately. The CCA results indicated tha...

Background Statistical models are regularly used in the forecasting and surveillance of infectious diseases to guide public health. Variable selection assists determining factors associated with disease transmission, however, often overlooked this process is evaluation suitability statistical model transmission outbreaks. Here we aim evaluate several modelling methods optimise predictive Ross R...

Ozone concentrations are valuable indicators of possible health and environmental impacts. However, they are also used to monitor changes and trends in the sources of both ozone and its precursors. For this purpose, the influence of meteorological variables is a confusing factor. This study presents an analysis of a year of ozone concentrations measured in a coastal Spanish city. Firstly, the a...

The aim of this study was to determine whether meteorological factors are associated with the timing of either onset of labor with intact membranes or rupture of membranes prior to labor-together referred to as 'the initiating event' of parturition. All patients delivering at Evanston Hospital after spontaneous labor or rupture of membranes at ≥20 weeks of gestation over a 6-month period were s...
