Both forms express the same physical principle. When applying the integral form, it is important to remember that the enclosing surface A must be closed; it encloses a finite volume V of the space through which the fluid flows. Some parts of the boundary surface may consist of real material...
Being able to focus on your science, rather than experimental set-up through ready-to-use application-specific method templates for common experiments, means that next break-through is closer than ever before...
Other typical assumptions include that there is no external friction (e.g., air resistance), and that external factors such as gravity can be ignored; however, this will depend on the specific case. One example of a mass-spring-damper system is an engine mount with dampers to reduce ...
The algorithms correct multiple spectra by identifying peaks that are common to all and, from those, computes a spectrum-specific correction. We show that these algorithms increase comparability within large datasets of spectra, facilitating comparative analysis, such as machine learning....

(MS)-based methodologies, these methods are less sensitive, specific and cannot perform simultaneous detection of multi-class plant hormones, thus, they have been phased out with modern approaches [20]. MS detection equipped with chromatographic techniques are the most widely used analytical approaches...
Conclusions Our results in principle accord with the notion that non-synonymous substitutions causing radical amino acid changes are more efficiently removed by selection in large populations, consistent with nearly neutral theory. These findings have implications for the use of d N /d S and sug...

An interface is designed in-house to extend the simulation to MWD calculation. Given a specific MWD curve as the...
specific amino acids.52In microorganisms, metabolic labeling can be achieved by simply adding salts of15N, and the organisms use the15N to make new amino acids and proteins. Heavy isotopes have been incorporated into a wide variety of organisms, includingSaccharomyces cerevisiae,Caenorhabditis elegans,...
