Plasmids, the circular DNAs shown in Fig. 1, are generally used for non-viral gene delivery. However, there are two major problems with most methods for delivering DNA to cellular chromosomes using plasmids, the most common form of non-viral gene delivery. First, expression of transgenes from plasmids is brief due to l...

One of the first machines to incorporate a D-shaped plasma was the JET, which began its design work in 1973. This decision was made both for theoretical reasons as well as practical; because the force is larger on the inside edge of the torus, there is a large net force pressing inward on the entire reactor. The D-shap...

Streamflow is measured as an amount of water passing through a specific point over time. The units used in the United States are "cubic feet per second", while in most other countries "cubic meters per second" are utilized. There are a variety of ways to measure the discharge of a stream or canal. A stream gauge provid...
