Sediment stratigraphy and diatom succession were studied in an 80.5-cm core taken from the deepest part of Third Sister Lake, a small kettle hole in a recently urbanized landscape of southeastern Michigan. Alternating light clay and dark organic bands documented sporadic inputs of clay from outside the basin during rain events, rather than annual laminations. Urban construction activity also di...

In order to illuminate the forming process of salted egg, the effects of the brine solution with different salt concentrations on the physicochemical properties, textural properties, and microstructures of duck eggs were evaluated using conventional physicochemical property determination methods. The results showed that the moisture contents of both the raw and cooked egg whites and egg yolks, ...

Through joined two sensitive methods solvation and cloud point extraction separated and determined micro amount of Ce(III) from aqueous solutions by using organic reagent 2,4-Dimethyl pentan-3-one (2,4-DMP) as extractant and non-ionic surfactant 1% TritonX-100 , the experimental study shows the solvation species of Ce+3 extracted into cloud point layer (CPL) have a wavelength for maximum absorb...

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 effect of dry salting during the cold-smoking process was evaluated on Atlantic salmon initially stored in refrigerated seawater (RSW) or ice. A 2D mathematical model developed from first principles, simulating heat and mass transfer at increasing duration. This validated using experimental values compared with empirical Zugarramurdi Lupín. predicted were used for water activity prediction ...

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...
