The frequency of parasitic contamination of public areas in the municipality of Pelotas, state of Rio Grande do Sul, Brazil, was studied between June 2010 and May 2011, when soil samples were collected from eight city squares. Out of 400 samples submitted to centrifugal floatation technique in solution of sodium dichromate with density of 1.35, 176 (44%) proved positive for at least one parasit...

Gas injection is widely used in secondary refining processes to homogenize chemical composition and temperature and to remove inclusions. It is an industrial requirement to minimize the size and concentration of inclusions in the product while minimizing production time to save energy and lessen refractory wear. Gas bubbling is effective to increase the cleanliness of steel mainly by two mechan...

A new anthelmintic drug Albenwas dazole (Zentel) was tested for its efficacy and tolerance in 100 children having single or mixed infestation with roundworms, hookworms, whipworms, pinworms and tapeworms. Their stools were examined by direct examination and by centrifugal floatation technique. The patients were observed carefully before and after treatment, for clinical efficacy, side effects o...

We demonstrate that superhydrophobic and superoleophobic nanocellulose aerogels, consisting of fibrillar networks and aggregates with structures at different length scales, support considerable load on a water surface and also on oils as inspired by floatation of insects on water due to their superhydrophobic legs. The aerogel is capable of supporting a weight nearly 3 orders of magnitude large...

gastrointestinal helminthes in domestic dogs in shiraz and the effect of age, sex, anthihelminth drugs, use of dog (pet or guard) and food on the infection rate were studied in 105 fecal samples.samples were collected directly from the rectum and examined by floatation method. data was analyzed by chi square test and fisher's exact test. no significant differences were found in male and fe...

Cryptosporidium sp. is a zoonotic intestinal protozoa in orangutans which transmitted through contaminated water (waterborne disease). This study aims to determine infects the sumatran orangutan (Pongo abelii) and bornean pygmaeus) North Sumatera Wildlife Park. The samples used were 3 fecal from different locations, two Medan Park one Pematang Siantar Animal Samples examined using floatation me...

The purpose of writing this review on floating drug delivery systems (FDDS) was to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. It is known that differences in gastric physiology (such as, gastric pH, motility) exhibit both intraas well as inter-subject variability demonstrating significant impact on gastric retention ti...
