Network security continues to gain relevance as the potential consequences of failure become more untenable. An inevitable side effect of the current expansion mode is the propagation of attack surfaces that has been engendered, requiring enterprises to look beyond prevention to face the reality of sec...
Metal-oxide-semiconductor field-effect transistors, also known as MOS semiconductor memory, was invented in 1959. This enabled the use of MOS transistors as elements for memory cell storage. MOS memory was cheaper and needed less power compared to magnetic-core memory. Bipolar memory, which used ...
Cole’s recent review of the efficacy of antidepressant drugs [1] suggests that we do not yet know whether the newer types of imipramine-like antidepressants are useful therapeutic agents. He also found little evidence in the literature for utility of the monoamine oxidase (MAO) inhibitors, and...
An experiment in the field can be conducted by adding nutrients to the crop at various rates. The resulting response ofyieldin relation to amounts of nutrients supplied will indicate the supplying power of the unfertilized soil in terms of bushels or tons of produce. If the increase in yield...
of deficiency must be determined, and the amount and kind of fertilizer needed for a given yield must be found. There is no substitute for detailed examination of plants and soil conditions in the field, followed by simple fertilizer tests, quick tests of plant tissues, and analysis of soils...

The static immersion test is a commonly used method to evaluate the release potential of the chemical components of solid materials. It can not only effectively solve the problem of water sample extraction in closed-pit mine goaves, but also facilitate the simulation of field conditions [16,17,...
