Missing data is one of the main difficulties in working with fluviometric records. Database gaps may result from stations components problems, monitoring interruptions and lack observers. Incomplete series analysis generates uncertain results, negatively impacting water resources management. Thus, proper missing consideration very important to ensure better information quality. This work aims a...

Since the conjecture of Richards (2008), work by Cairns et al. (2016) and subsequent developments Boumezoued (2020), (2020) (2019), it has been acknowledged that observations from censuses have led to major problems reliability in estimates general population mortality rates as implemented practice. These issues mis-interpretation some key characteristics past decades, including ”false cohort e...

Monthly data on the $US/ECU exchange rate are analysed in light of the random walk hypothesis. A battery of tests, including procedures that are robust to conditional heteroscedasticity, are applied against linear alternatives to departures from the random walk. These tests are all based on the sample autocorrelations of the series of first differences of the logarithm of the monthly exchange r...

Methods We evaluated 83 consecutive patients with suspected PH referred for CMR between January 2009 and July 2010. Imaging was performed on a Philips 1.5T MRI scanner. Retrospectively gated cines of a short axis stack were obtained using SSFP (temporal resolution 25-40 ms). LGE images of the same views were obtained 10 minutes after infusion of Gd-DTPA (0.2 mmol/kg) using phase sensitive inver...

results there was a significant positive correlation between increase in the monthly average temperature, the number of rainy days, and the number of frost days with the number of rta (p < 0.05). increased monthly average relative humidity, evaporation, and number of sunny days were negatively correlated with the frequency of rta (p < 0.05). we also observed an inverse significant correlation b...
