BACKGROUND The recently launched Pneumo Rischio eHealth project, which consists of an app, a website, and social networking activity, is aimed at increasing public awareness of invasive pneumococcal disease (IPD). The launch of this project was prompted by the inadequate awareness of IPD among both laypeople and health care workers, the heavy socioeconomic burden of IPD, and the far from optima...
With ongoing climate change, analysis of trends in maximum annual daily river flow is interest. Flow magnitude and timing during the year were investigated this study. Observations from 11 unregulated rivers northern Sweden analysed, using extreme-value distributions with time-dependent parameters. The Mann–Kendall test was used to investigate possible trends. statistics revealed no significant...
In recent decades, an increase in the number of extreme flood events as well drought has been observed Slovenia. This rise need for a comprehensive analysis trends discharge data series. study, statistical seasonal and annual mean, maximum, low values were investigated using Mann Kendall test. The results show temporal spatial variability discharge. general, decreasing trend water quantities ri...
Abstract In this study, the runoff data from 12 representative stations in Yellow River 2005 to 2020 is utilized, and Mann-Kendall trend test used examine changes observed of River. The results show that annual has grown upper reaches gradually reduced along river flow direction. It because mainly affected by precipitation human activities. addition, mutation each hydrological station not consi...
A new nonparametric test for two sample problem based on order statistics is suggested. This test can be successful in the case of small samples. The probabilities of the statistic are given. Comparisons with KolmogorovSmirnov, Mann Whitney-Wilcoxon, and Wilks’ empty block test for small sample sizes are made by the simulation.
Three timescale i.e. monthly, seasonal and annual rainfall data of Bundelkhand region, Central India, was analyzed for 40 years (1981-2020). The mean average the region ranges between 657.7 mm 1146.4 studied period with month August receiving highest amount rainfall. receives about 90 % its during South West Monsoon from June to September. Temporal trend different analysed using nonparametric M...
This analysis was conducted on 31 synoptic stations in Iran. Initially, the Mann-Kendall test was administered in order to analyse the trend of alterations of these two components over time and the results suggest that 16% of the stations show significant relationship with annual precipitation (positive and negative). More stations showed significant relationships between sunspots and minimum a...
