The typical rotary screw compressor stage is made up of two rotating shafts, or screws. One is a female rotor and the other a male rotor. These two rotating components turn counter to one another (counterrotating). The two rotating elements are designed so that as they rotate opposite to one another their respective helix forms intermesh (see Figure 3-78). As with all rotary compressors, there are no valves. The gas is sucked into the inlet post and is squeezed between the male and female... 

Overthinning is also frequently responsible for running and sagging, which in turn promotes excessive pigment flotation. If application is by spraying, this can be countered by the use of thinners which evaporate quickly. In brushing, however, such thinners would cause dragging of the brush. If the evaporation rate of thinners is too fast, they may promote... 

Some experimenting nught be necessary if it turns out that quadratic terms such as improve the fit between the model and the data. However, the relevant point is that such a model is only a means to refine and speed up the process of finding optimal conditions. For this purpose it is counter-productive to try for a perfect fit, it might even be advantageous to keep the model simple and throw out all but the best five to 10 experiments, choose new conditions, and then return to the work bench. 

Carrier generators in molecular conductors have been associated for a long time to a partial charge transfer between the HOMO (or LUMO) electronic band and other chemical species. These systems are known as two-component molecular conductors. Tetrathiofulvalene derivatives are versatile systems for the formation of molecular organic conductors due to their electron donor capacity by transferring one u-electron from the HOMO orbital, and to their planar shape that promotes their stacking as a consequence of the n-n orbital overlap. The electronic properties of these salts are essentially determined by the packing pattern of the donor molecules which, in turn, depends on the counter-ion. 

The object is to determine not only whether the symptoms of a particular disorder of the CNS can be explained by the malfunction of a certain NT but whether drugs which are known to be effective in a disorder have a distinct effect on one NT system. These objectives are not unrelated since if a disorder is shown to be due to the increased activity of a particular NT then at least some drugs which are effective in its treatment could be assumed to work by decreasing the function of that NT. Similarly if a whole range of drugs are found to be effective in a certain disorder and all increase the activity of one NT then the disorder could in turn be due to a reduced function of that NT. Ideally one would hope to establish the NT malfunction that causes the disorder and then develop appropriate drugs to counter that malfunction and treat the disorder. In practice this has rarely happened, mainly because of the difficulty of establishing a true NT malfunction in humans.
