Wandering effect

Chemical reactions form the heart of chemistry. And there is no more important aspect of chemical reactions than the energy effects that are caused. You will realize this if you let your thoughts wander between the warmth the little child in the fable derived from the combustion...

It was nearly two years before we could begin to put our plans into effect. Late in August of 1969 fate turned me from hash smuggler to fugitive when one of my Bombay-to-Aspen shipments fell into the hands of U. S. Customs. I went undergroud and wandered throughout Southeast Asia and Indonesia, viewing... 

Dennis and Vanessa were called out of the hut, and they agreed that the effect was remarkable. I wandered away as they began to speculate on the causes—the time of day, the light conditions, optical illusions, and all the rest. I seemed to have no heart for these arguments each time they broke out, I found myself with some deep, inner assurance that the situation was moving forward just as it should and that everyone was playing a part and doing it very well. 

The appearance of an electron on a level A denotes the transition of the chemisorbed particle C from a state of weak to a state of strong acceptor bonding with the surface. This may be effected in two ways, as is seen from Fig. 10 by a free electron of the conduction band falling onto level A or by an electron of the valence band being thrown onto level A. The removal of an electron from the level D denotes the transition of the chemisorbed particle C from a state of weak to a state of strong donor bonding. This may also be effected in two ways by the recombination of an electron of level D with a free hole wandering in the valence band or by the ejection of this electron from level D into the conduction band. 

Technically this means rather more than bad conductor . Metals conduct electricity because some of their electrons come free of their parent atoms and are at liberty to roam through the material. Their motion corresponds to an electrical current. A semiconductor also has wandering electrons, but only a few. They are not intrinsically free, but can be shaken loose from their atoms by mild heat some are liberated at room temperature. So a semiconductor becomes a better conductor the hotter it is. Metals, in contrast, become poorer conductors when hot, because they gain no more mobile electrons from a rise in temperature and the dominant effect is simply that hot, vibrating atoms obstruct the movement of the free electrons. 

The naphthol (60) is a representative of a class of compounds termed development inhibitor release couplers. Phenylmercaptotetrazole is released from this coupler during dye formation. The thiol can then inhibit development within the layer in which it is formed thereby causing a beneficial effect which is displayed in the form of a sharper image. Where the thiol wanders into an adjacent layer and causes inhibition of development some correction for the unwanted absorption of the image dye can be achieved (69MI11401). 

QUALITATIVE COMMENTS (with 50 mg) My tongue feels as if I had eaten hot food. Overall 1 gotup to a plus 1, and found the effects to be completely benign. I wandered about within the Graves exhibit at the Oakland Museum but there seemed to be only minor enhancement of the visual input. ...

When the dose goes above 500 to 1000 meg the effects can be very alarming. I have seen people get up and lunge around the room, falling over furniture, babbling incomprehensible nonsense and knocking their heads into walls. Several people have tried to wander out of the house. When the experience is over, they have no memory of any of this. In fact, they usually remember very different events. To an... 

Research discussed in this paper continues our concern with the use of periodic operation to increase catalyst activity. Questions addressed are 1) can periodic operation improve activity in a "hydrogenation" reaction which does not appear to proceed via a redox mechanism 2) will "resonance" effects be observed 3) will non-uniform, but still periodic, concentration square waves be more effective than uniform square waves and 4) will the behavior under periodic operation of a fixed bed reactor with relatively large conversion differ significantly from the behavior in a differential reactor Because hot spot location and magnitude depend on feed conditions, periodic operation should cause the hot spot to wander and should diminish its magnitude. This supposition was examined experimentally in our study.
