B. Medium preparation and sterilization: A 450-liter fermentor was filled to 190 liter with water containing Sigma corn steep liquor (600 g-3.0 g/l) and MAZU 204 antifoam (10 ml-0.05 ml/l). This solution was sterilized for 60 minutes at 121° C., and then cooled to 36° C. The ...
For each metabolite, we calculated the temporal variation, using the coefficient of variation (CV): $$ \mathrm{C}\mathrm{V} = \sigma /\mu, $$ where σ and μ are the standard deviation and mean of the measurements across the time points respectively. AP-MALDI of intracellular metabolites...
What is claimed is: 1. A compound of the following Formula (I), a pharmaceutically acceptable salt thereof: in the formula, R1 is a hydrogen atom, methyl, or a halogen atom; R2 is a hydrogen atom; a straight or branched C1-C6 alkyl group unsubstituted or substituted with a straight or...
Process gps data and calculate night/day, delta in time, and calculate hours in the cosine of radians - we will see what this does below. gps.1 <- gps %>% mutate(ID = paste(species, id), .before = date.time) gps.1 <- gps.1 %>% mutate(Hour = hour(date.time.mst), Min =...
If you have special package requirements, we will pack as required, but the fees will be paid by customers. 10. Q: How to keep your equipment from corrosion? A: We use the world-famous paint, like SigmaCoatings, PainBow,etc. What's more, we paint...
