OBJECTIVE The study aimed to assess bronchopulmonary dysplasia (BPD) as a predisposing factor for alteration in the psychomotor development index (PDI) in premature infants and verify the incidence of neuromotor alterations at 6 months corrected age. METHOD This was a prospective cohort study that followed the neuromotor development of 152 very low birth weight premature infants, with psychom...

Chemical weathering indices are commonly used for characterizing weathering profiles by incorporating bulk major element oxide chemishy inlo a single metric for each sample. Generally, on homogeneous parent rocks, weathering indices change systematically with depth. However, the weathering of heterogeneous metamorphic rocks confounds the relationship between weathering index and depth. In this ...

River regulation is challenging when there diverse upstream and downstream interest, leading to regional international conflict. However, quantifying the upstream-downstream flow regime changes their causes are given less consideration in river basin. In this study, we presented three new ratios for downstream-upstream low contribution (DUL), high ratio (DUH), meteorological-hydrological drough...

This research paper reveals lithology some major elements content (SiO2, Al2O3, TiO2, Fe2O3, MgO, K2O, Na2O, MnO P2O5) core sediments their distribution along depth Chemical Index Alteration (...

Wettability alteration has been a sophisticated issue for scientists and reservoir engineers since early 20th century; thus, many investigations have been carried out to determine wettability and enhance it to ideal conditions, which leads to improvement in oil recovery. Dilute surfactant flooding has been approved as one of the noteworthy methods in chemical flooding. Several petroleum reservo...

Geometallurgy tries to predict the instability the behavior of ores caused by variability in the geological settings, and to optimize the mineral value chain. Understanding the ore variability and subsequently the process response are considered to be the most important functions of an accurate geometallurgical study. In this paper, the geometallurgical index is presented as a new tool to...
