The idea that the physical properties of cuticular lipids affect cuticular permeability goes back over 65 years. This proposal has achieved textbook status, despite controversy and the general lack of direct supporting evidence. Recent work supports the standard model, in which lipid melting results in increased cuticular permeability. Surprisingly, although all species studied to date can synt...

The activity of Aspergillus orzae nuclease S1 on DNA has been investigated under varying pH and metal ion conditions. Nuclease S1 was found to preferentially digest denatured DNA. With native DNA as substrate the enzyme could only digest the DNA when caffeine was added to the reaction mixture. The enzyme was more active in sodium acetate buffer (pH 4.5), than in either standard saline citrate (...

Metals and alloys in amorphous state are promising for the use as structural functional materials due to their superior properties related absence of such defects grain boundaries dislocations. Obtaining requires quenching from liquid with a high cooling rate. In conventional technologies, this is reason considerable size limitation hindering application alloys. Additive manufacturing (AM) free...
