An efficient metal free protocol has been developed for the synthesis of benzylic esters via a cross dehydrogenative coupling (CDC) involving alkylbenzene(s) as a self- or as a cross-coupling partner(s) via the intermediacy of Ar-COOH and the benzylic carbocation obtained from the other half of the alkylbenzene; both symmetrical as well as unsymmetrical esters can be prepared using Bu4NI and TBHP.

One of the efforts to minimize impact detergent waste pollution is by adsorption using coffee dregs and coconut adsorbents. The purpose this study was determine optimum mass grounds pulp as adsorbents, compare effectiveness their absorption in decreasing levels Linear Alkyl Benzene Sulfonate, isotherm models. This research conducted batches with variations each adsorbent, namely 1 gram, 2 grams...

Emerging pollutants have been ubiquitously found in environmental compartments, while there is scarce information about these substances and their effects on health status wild terrestrial mammals. Bat species are very sensitive animals to any changes the environment considered one of best bioindicators quality wildlife. To acquire a better knowledge exposure animals, multiclass method proposed...

The shifted number system is presented: a method for detecting and avoiding error producing carries during approximate computations with truncated expansions of rational numbers. Using the shifted number system the high-order lifting and integrality certification techniques of Storjohann 2003 for polynomial matrices are extended to the integer case. Las Vegas reductions to integer matrix multip...
