SolWat is a hybrid photovoltaic (PV) and photochemical technology, which integrating PV module water disinfection reactor on top of it, was developed to meet the needs safe drinking-water electricity in developing countries. This paper assessed effects electrical performance integrated into system regarding different hydraulic retention times (HRT) technologies. With this aim, several tests wer...

The proposed model is based on the measurement of the retention times of 346 tryptic peptides in the 560- to 4,000-Da mass range, derived from a mixture of 17 protein digests. These peptides were measured in HPLC-MALDI MS runs, with peptide identities confirmed by MS/MS. The model relies on summation of the retention coefficients of the individual amino acids, as in previous approaches, but add...

The retention behavior of molecular species of phosphatidylcholine (PC) is studied by reversed-phase (RP) ion-pair high-performance liquid chromatography (HPLC). Mobile phases contain tetraalkyl ammonium phosphates (TAAPs) in methano-acetonitrile-water. The stationary phase is alkyl-bonded silica. Competitive interactions of TAAPs, analyte solutes, and an RP-HPLC column result in reduced retent...

Objectives To investigate mortality in men admitted to hospital with acute urinary retention and to report on the effects of comorbidity on mortality. Design Analysis of the hospital episode statistics database linked to themortality database of the Office for National Statistics. Setting NHS hospital trusts in England, 1998-2005. Participants All men aged over 45 who were admitted to NHS hospi...

Quantitative structure-retention relationship (QSRR) analysis is a useful technique capable of relating chromatographic retention time to the chemical structure of a solute. A QSRR study has been carried out on the reversed-phase high-performance liquid chromatography retention times (log tR) of 62 diverse drugs (painkillers) by using molecular descriptors. Multiple linear regression (MLR) is u...
