Drought is a climate phenomenon which might occur in any climate condition and all regions on the earth. Effective drought management depends on the application of appropriate drought indices. Drought indices are variables which are used to detect and characterize drought conditions. In this study, it was tried to predict drought occurrence, based on the standard precipitation index (SPI), usin...

This study provides a comprehensive evaluation of mean and extreme precipitation features over Aotearoa New Zealand (hereafter or NZ) in station data six merged satellite-gauge products, five reanalyses two situ gridded products period 10 years inclusive (2001–2010). All show similar pattern with clear maximum alpine regions. However, only the higher spatial resolution datasets capture details ...

Combination of electro-Fenton (EF) process with other advanced oxidation processes (AOPs) is found very much effective for water and wastewater treatment. The combined including sono-EF (SEF), photo-EF (PEF), electro-peroxone, ferrate-EF EF persulfate allow enhancing the mineralization efficiency treatment as well reducing operational cost toxicity treated wastewater. Even though, there are sev...

introduction spiral conveyors effectively carry solid masses as free or partly free flow of materials. they create good throughput and they are the perfect solution to solve the problems of transport, due to their simple structure, high efficiency and low maintenance costs. this study aims to investigate the performance characteristics of conveyors as function of auger diameter, rotational spee...

background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...
