Spam and phishing emails are not only annoying to users, but are a real threat to internet communication and web economy. The fight against unwanted emails has become a cat-and-mouse game between criminals and people trying to develop techniques for detecting such unwanted emails. Criminals are constantly developing new tricks and adopt the ones that make emails pass spam filters. We have devel...

We present a method for DNA extraction from peripheral blood using sugar, commercial detergent, and sodium salt. Our method is simple, fast, and inexpensive; its qualitative parameters do not significantly differ from the standard salting-out procedure.

The aim of this study was to compare different DNA-extraction methods and selective enrichment broths for their effectiveness to detect Salmonella Typhimurium in artificially inoculated swine feces samples (100 CFU/ g) by polymerase chain reaction. After enrichment in Rappaport-Vassiliadis, selenite cystine or MüllerKauffmann tetrathionate, aliquots were used for DNA extraction by three differe...

The effects of cosolvents on the solubility and hydration of small nonpolar solutes in solution has been investigated using a combination of molecular dynamics simulation and Widom particle insertion calculations. Results were obtained for helium, neon, argon, and methane solutes in solutions of sodium chloride, ammonium sulfate, calcium chloride, ammonium acetate, tetramethylammonium chloride,...

Sodium chloride salting-in and microwave irradiation were combined to drive thermolysin molecules into mesoporous support to obtain efficiently immobilized enzyme. When the concentration of sodium chloride was 3 M and microwave power was 40 W, 93.2% of the enzyme was coupled to the support by 3 min, and the maximum specific activity of the immobilized enzyme was 17,925.1 U mg(-1). This was a 4....

Duck eggs are an animal food that can be consumed. In community life, generally there two ways of salting, namely the first with water, salt, and bricks. The process mixing water salt still uses manual method, by hand. Salt is a major factor in salting which functions as preservative to prevent spoilage eggs, thereby increasing their shelf life. order become salted general, preservation. method...
