We studied and quantified the elimination of sunflower oil from a wastewater influent using a biological treatment by activated sludge. Estimation of the biodegraded material was obtained doing a mass balance, and we conducted a follow-up of the different operational parameters and design. We delivered information about the operation of a system for treatment by activated sludge fed with an inf...

A CULTURE of a new Salmonella type of organism was received during August, 1952; it had been isolated from several patients suffering from food poisoning at Seremban, Malaya (Robinson, T. M., 1952, personal communication). On desoxycholate-citrate agar this organism produced non-lactose fermenting colonies typical of the Salmonella group. It is a Gram-negative, motile rod with the following bio...

background & aim: according to the increase in diseases such as diabetes and obesity, using of saccharose alternatives for producing of low-calorie and sugar-free alternatives, are taken into consideration of researchers and industrialists. among them, steviosidewith the 300 times more sweetness than saccharose has special place, due to is a natural. the aim of this study is optimizing of stevi...

Micrometer size activated porous carbon spheres doped with nitrogen and sulfur (NSAPC) are synthesized hydrothermally by using saccharose as the precursor l-cysteine doping agent, followed KOH activation. These possess a high specific surface area (SSA) porosity (mainly microporous) suitable for efficient charge storage. Additionally, significantly changes chemistry. When tested electrode mater...
