    Abstract: A study was conducted to investigate the capacity of Tanzanian kaolin-feldspar blends on water defluoridation. Five adsorbents of kaolin-feldspar blends were prepared at different ratios, namely; 1:0, 1:1, 1:2, 2:1 and 0:1.The prepared adsorbents were activated at 60°C and then characterized by XRD and XRF. Mineralogical results showed that kaolin ... Show More

    Abstract: The betacarotenes rate in a V volume extracted on unrefined palm oil by acetic acid solvent was given by dosage with hydrofluoric acid. This dosage of betacarotenes by hydrofluoric acid was investigated like a process. We used Statistical Process Control SPC to exploit the dosage results in V volume and we noticed that these data follow a normal di... Show More

    Abstract: The theoretical study on the molecular structure of a serie of p-aminophenyl benzene-fused bis tetrathiafulvalenes is presented. Optimized geometry of the title compound was calculated using DFT method at the level of B3LYP theory and 6-31G(d,p) basis set. The HOMO and LUMO analysis were used to determine the charge transfer within the molecule and... Show More
