Heat protection principles

Treatment principle Intensively clear heat, protect the body fluids and vent the pathogenic heat... 

The rate of heat transfer by radiation between two surfaces may be reduced by inserting a shield, so that radiation from surface 1 does not fall directly on surface 2, but instead is intercepted by the shield at a temperature Tsh (where 7, > T,h > T2) which then reradiates to surface 2. An important application of this principle is in a furnace where it is necessary to protect the walls from high-temperature radiation. 

Incidentally, there are customers who come and ask, I know you have stated in your Abs Max table that I shouldn t apply more than 24V to the device. But what if I apply 28V for just lms The principled answer to that is, you can t apply even 24.01V, for even 10-12 seconds The company officially doesn t stand by it. Yes, internally they do test at higher stress levels than published, and have also got various guard-bands present (for their protection and reputation). But remember you don t know what these are. Also, keep in mind that voltage overstress leads to almost instantaneous death, whereas current ratings are related more to internal heat buildup, so you can always exceed them somewhat for a short time. 

As soon as a treatment principle is established, the composition plan and treatment strategies can be arranged. For instance, to treat the syndrome of excess heat in the Lung and Stomach, one would first prescribe herbs that have sweet-cold, bitter-cold or salty-cold properties, and which have the functions of clearing heat and reducing fire in the Lung and Stomach. Second, herbs that are sweet and cold and that can nourish body fluids and protect the Yin, which has been severely consumed by the excess heat, should be selected. Herbs that can tonify the Qi should be selected if the Qi is weakened severely by the heat. Herbs that moderate the actions of the harsh herbs in the formula, and reduce their side effects, should also be added. 

Treatment principle Separate dampness and heat by dispersing, transforming, drying and draining damp-heat regulate the Qi protect and strengthen the function of the Spleen... 

A special short-lime performance of thermal insulation is the ablative protection on the bottom of asiroitautical capsules returning from outer space when they are heated to sudden high temperatures by impact with the atmosphere. As principles stated below indicate, ablation is the process of resisting heat flow by using absorplancc in changes of slate from solid to liquid and lo sapor of the ablative insulation, which is [hereby lost, so that a one-time or at most a lew times of exposure is practicable. 

An amino acid protected only at the N atom and a different amino acid in which only the C02H group is protected do not react with each other to form a peptide bond. On the contrary, they form an ammonium carboxylate in a fast acid/base reaction (Figure 6.29). Ammonium car-boxylates can in principle be converted into amides by strong heating. Thus, for example, in the industrial synthesis of nylon-6,6, the diammonium dicarboxylate obtained from glutamic acid and hexamethylenediamine is converted to the polyamide at 300 °C. However, this method is not suitable for peptide synthesis because there would be too many undesired side reactions. 

The methods that will be dealt with here are those used to obtain hydrocarbon vapours from this first phase. The treatment of plastic wastes of all sorts by pyrolysis, being still in its early stages, workers keeping practised procedures confidential, and often protects them by patents. As a consequence, this chapter deals exhaustively only with the procedures that have been personally tested and developed by the author. The general principle of polyolefin waste pyrolysis consists of heating plastic materials in isolation to a sufficient temperature such that the polymers decompose into small hydrocarbon molecules. 

I was struck by the great stability of the superconducting state, and it occurred to me that if nature wanted to protect the information contained, say, in the genetic code of a species against the ravages of heat and other external influences, the principle of superconductivity would be well suited for the purpose.
