Transparencies transparency speak

In situ UV-visible spectroscopy monitors the energy of electrons within the analyte. While, strictly speaking, all materials change their UV-visible spectrum in accompaniment with electrode reactions (they are said to be electrochromic), the majority of these changes are not discernible by the human eye, and therefore may not be useful to the analyst. Electrodes must be optically transparent for in situ work, with the most commonly used being a thin film of the semiconductor, indium-tin oxide, on glass. 

It seems that we re always in the middle of an election. And elections mean speeches stump speeches, impromptu speeches, TV speeches, speeches after dinner, speeches in schools, and speeches in malls. With the prevalence of standup public speaking in the political arena, it would be easy for the new engineer to become confused and assume that the same mode is commonplace in business communication. The truth is that it is the rare businessperson today who gives a stand-up speech, at least for everyday business matters. With the advent of overhead projectors and transparencies, businesspeople stopped giving speeches and started making presentations talks supported by projected visual material. The advent of laptop computers, LCD (liquid-crystal display) projectors, and powerful presentation software has advanced this trend. 

To get in the mood to speak transparency, I find it useful to grab The Wall... 

Don t fidget with transparencies or laptops while you speak. 

It may he remembered that Pliny speaks of the uses of glass for imitating precious stones, and that he also remarks that there are hooks, the authors of which I refrain from mentioning, which give instructions how to stain crystal in such a way as to imitate emeralds and other transparent stones. . . and there are no frauds which bring greater profits. ... 

Emulsions made by agitation of pure immiscible liquids are usually very unstable and break within a short time. Therefore, a surfactant, mostly termed emulsifier, is necessary for stabilisation. Emulsifiers reduce the interfacial tension and, hence, the total free energy of the interface between two immiscible phases. Furthermore, they initiate a steric or an electrostatic repulsion between the droplets and, thus, prevent coalescence. So-called macroemulsions are in general opaque and have a drop size > 400 nm. In specific cases, two immiscible liquids form transparent systems with submicroscopic droplets, and these are termed microemulsions. Generally speaking a microemulsion is formed when a micellar solution is in contact with hydrocarbon or another oil which is spontaneously solubilised. Then the micelles transform into microemulsion droplets which are thermodynamically stable and their typical size lies in the range of 5-50 nm. Furthermore bicontinuous microemulsions are also known and, sometimes, blue-white emulsions with an intermediate drop size are named miniemulsions. In certain cases they can have a quite uniform drop size distribution and only a small content of surfactant. An interesting application of this emulsion type is the encapsulation of active substances after a polymerisation step [25, 26]. 

Gases and liquids are partly transparent to thermal radiation. Therefore emission and absorption of radiation takes place inside the gas or liquid space. In gases and liquids emission and absorption are volumetric effects. In contrast, on the surface of a solid object, radiation is completely absorbed within a very thin layer (a few micrometres). Radiation from the interior of a solid body does not penetrate the surface, emission is limited to a thin surface layer. It can therefore be said that emission and absorption of radiation by a solid body are surface effects. This means that it is allowed to speak of radiating and absorbing surfaces rather than correctly of radiating solid bodies. 

If a thing is deprived of its heat, then is there no motion in it. In the order of Nature the father changes into the son, which means that the Spiritual is materialized, and the Volatile made permanent or that Sun and Moon have come home. Of these two planets SENIOR speaks also I am a hot and dry Sun, while thou, LUNA, art cold and moist, and when we shall rise in the order of our most ancient nobility, a burning light will be poured into us. Whereby he is indicating that through the knowledge and mastery of the ancients the renewals of the moistures will be received, and Sun and Moon become transparent. 

Using a computer projection panel combined with an overhead projector eliminates the need to create transparencies or worry about picking up the wrong one while speaking. A press of a button on the computer mouse can kev the appropriate image during a presentation. A speaker can commit an entire visual presentation to a computer disk and revise it for later presentations. 

If you need to use a complex visual aid, build from a simpler one. The first page of a flip chart could include a simple chart, the second page could include a more detailed version of the same chart, and so on. Some speakers show a transparency with parts left out and then add the parts while speaking or else add additional transparencies as overlays.
