Jan 07, 2021 In the present study, we are interested in investigating the relation between the pathogenicity of SRVs and the solvent accessibility of the residue undergoing variation. For this reason, we firstly computed Accessible Surface Area (ASA) values for all 1,285 protein chains included in the HVAR3D dataset using the DSSP program (Kabsch and Sander ...

Thus since 1 tonne of mill-run bagasse can be replaced by 0.173 tonne of fuel oil, worth US$ 80/tonne or again by 0.263 tonne of bituminous coal worth US$55/tonne, it can be said that bagasse is worth between US$ 13.8 and 14.5 per tonne (mill-run weight, 50 percent moisture content) and a figure of US$ 15 can be used as a rounded representative ...

The relationship between the amount of ATP on the sample and the RLU result reading on the luminometer is simple: The RLU reading is directly proportional to the amount of ATP collected from the sample. A high RLU reading indicates a large amount of ATP at the test location. This in turn indicates improper cleaning and the presence of contaminants.

One must not be afraid to use high rotational speeds. If e.g. an dissolver disc of 25 mm diameter is used, the DISPERMAT must be run at a rotational speed of 15.000 rpm in order to obtain peripheral velocities of 20 m/s. The final dispersion result is normally reached after 10 to 15 minutes.

Utilization of petroleum coke in the rejuvenating Nigerian metallurgical industry is currently satisfied by importation from more industrialized nations of the world such as the USA, Brazil and Venezuela where delayed coking plants operate and grow in number. The sad years of poor planning have revealed lapses in integration and synergic planning of our industrial complex.

The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill.
