BACKGROUND Total fertility rate (TFR) is high and at a static level for the last two decades in Bangladesh. Reduction of fertility by increasing contraceptives use could reduce maternal and neonatal mortality. To achieve the targeted contraceptive prevalence rate (CPR) of Family Planning 2020 (FP2020) Initiative, it is important to increase CPR in all regions of the country. However, it is lowe...

q-mode hierarchical cluster (hca) and principal component analysis (pca) were simultaneously applied to groundwater hydrochemical data from the three times in 2004: june, september, and december, along the ain azel aquifer, algeria, to extract principal factors corresponding to the different sources of variation in the hydrochemistry, with the objective of defining the main controls on the h...

Due to the stochastic nature of source, wind turbines operate under non-stationary conditions and extracted power depends non-trivially on ambient working parameters. It is therefore difficult establish a normal behavior model for monitoring performance turbine most employed approach be driven by data. The curve relation between intensity widely performance. On grounds above considerations, rec...

in this paper, multivariate calibration methods of partial least squares (pls) and principle component regression (pcr) were investigated in simultaneously determination of hydrazine (hz) and acetylhydrazine (ahz). the aforementioned methods are based on formation of the silver nanoparticles (agnps) from the reaction of hz and ahz with ag+ ions as oxidizing agent in the presence of citrate ions...
