WebNon-invasive flow measurement with the FLUXUS G ultrasonic measuring system proved to be the ideal solution. Since clamp-on transducers are simply mounted on the outside of the pipe, there is absolutely no risk of contamination and modifications made to the measuring point do not have any effect on the production process.

WebThe strength of a barrier to gene exchange, whether due to a physical obstacle or to genetic incompatibility, can be measured by a quantity B. This has the dimensions of distance, and can be thought of as the length of habitat which would pose the same obstacle to the steady flow of a neutral allele. Web'Gene flow' means the movement of genes. In some cases, small fragments of DNA may pass from one individual directly into the germline of another, perhaps transduced by a …

Web19 apr. 2024 · Gene flow is the directional movement of genetic material from one population to another resulting from seed and pollen dispersal over space and time. For a given pair of populations, rates of historic gene flow in each separate direction can be estimated from allele frequency data (SI Appendix, Fig. S1) (e.g., refs. 19, 20). WebGet started with gene expression using q PCR. One of the most widely used methods for analyzing gene expression is qPCR, also called real-time PCR. qPCR is performed as a one step or two step process. One‑step qPCR requires converting the RNA into DNA (called cDNA), then measuring the resulting cDNA concentration. All of this is done in a single tube.
