4.With over 10 years of manufacturing experience, Yuh-Dak, an active market player, has developed and produced high-precision machines that are customized to market trends and easy to maintain.
5.Dranchuk Abu Kassem model (DAK model) is the most frequently used for calculating gas compressibility factor. Its application showed that the method was not accurate enough for calculating the compressibility of high pressure gas.
6.The degrading rate of 50 mg/kg MP in non-sterile and sterile soil of chemotaxis mutant DAK is about 20%～30% lower than that of wild-type bacterial DLL-1.Lose of chemotaxis in DLL-1 would decline its degradation ability of MP. It was demonstrated that chemotaxis plays an important role in the in-situ biodegradation of pesticides.
