Warmth

For the examination of the applied metallic or ceramic layer, the test object is heated up from the outside The heat applying takes place impulse-like (4ms) by xenon-flash lamps, which are mounted on a rack The surface temperature arises to approx 150 °C Due to the high temperature gradient the warmth diffuses quickly into the material An incorrect layer, e g. due to a delamiation (layer removal) obstructs the heat transfer, so that a higher temperature can be detected with an infrared camera. A complete test of a blade lasts approximatly 5 minutes. This is also done automatically by the system. In illustration 9, a typical delamination is to be recognized. 

Fig. 1. Schematic of the cross section of a mammal s skin. The relative size and function of the parts depend on the species and breed of the animal. For goats, where the wool or hair is sparse because it is not needed for warmth, the skin is dense to provide protection for sheep protected primarily by heavy wool, the skin contains more oil (sebaceous) glands to lubricate the wool for catde, both the hair and the heavy hide stmcture protect the animal (3).

Finishing of Wool. Wool (qv) competes for markets where warmth, wrinkle recovery, and abiUty to set in creases are important. Wool problems relate to shrinkage, particularly to its tendency to felt. This is caused by scaly stmcture, which tends toward fiber entanglement when wet and subjected to mechanical action. In order to compensate for this tendency, wool needs to be set and also made shrinkproof if it is to be laundered. 

Thickness. Because two fabrics that have identical weight per unit area values may have widely varying bulks, the specification of thickness is essential for properly characterizing a fabric. Fabric thickness has been shown to be direcdy proportional to thermal insulation, or warmth (121). Fabric warmth is the result of the entrapment of air between fibers and yams. A thicker fabric in general allows an increased amount of entrapped air and thus is warmer. 

Resilience of textile fabrics when compressed in the bent state is related to wrinkle resistance and retention of shape, drape, and hand. Resilience is an important parameter for evaluating blankets, wearing apparel in which warmth is a factor, pUe fabrics including carpets, and bulk fiber utilization in mattresses, cushions, etc. The general method for determining compressional resilience is to compress and unload the material cycHcahy, creating a plot of compressive force versus fabric thickness. 

The main agents of these losses are the microbes and small animals, such as springtails and mites, that inhabit the soil. These feed on organic matter that contains carbon and nitrogen and produce carbon dioxide and ammonium ions as waste products. Other bacteria convert the ammonium to nitrate. Like most of us, these organisms are most active when the conditions suit them best, and their preferred options are warmth and moisture. In early autumn, the soil is still warm... 

In the event of frost-bite do not rub the affected area but immerse rapidly in warm water and maintain general body warmth. 

The sensation of warmth or coldness is caused by temperature. Adding heat to a substance not only raises its temperature, but also produces changes in several other qualities. The substance expands or contracts its electric resistance changes and in the gaseous form, its pressure changes. Five different temperature scales are in use today Celsius, Fahrenheit, Kelvin, Rankine, and international thermodynamic. 

The temperatures monitored in Fig. 5.2 are used by the brain to regulate shivering, blood flow to the skin, and sweating. The sensed temperatures also contribute to our overall feelings of warmth and other thermal sensations. 7 hermal sensation (TS) can be predicted over a wide range of activities (0.8 to 4 met) from simple deviations in the mean body temperature (T j,) from the mean bodv temperature when the person feels neither warm or cool but neutral (Fig. 5.2). 

Equivalent warmth An early UK thermal comfort scale devised by Bedford. 

Warmth The state or quality of the body being warm it is not necessarily a state of thermal equilibrium. 

Hand-wftrme, /. heat (or warmth) of the hand, -werfer, m. (Mil.) mortar, -werk, n. handicraft, trade guild, -werker, m. mechanic, artisan, workman. 

Andrei Sakharov was born in Moscow, Russia, to a family of the intelligentsia on May 21, 1921. His father, Dmitri, taught college physics and wrote textbooks and popular science books. Sakharov studied at home until the seventh grade. Dmitri, a man of warmth and culture, was his first physics teacher. 

This organization of the information was quite an aid in his quest for warmth. However, as tree limbs and broom handles became scarce, the child tried to find a regularity that would guide him to new burnable materials. Looking at the pile of objects that failed to burn and comparing it with the pile of objects that would burn, the child noticed that a regularity appeared. He proposed a possible generalization. ... 

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... 

We do not need a hand lens to feel the energy of light rays. Just remember those lazy afternoons you spent last summer soaking up the warmth of the sun. The afternoon pleasure... 

Nicotinic acid may cause nausea, vomiting, abdominal pain, diarrhea, severe generalized flushing of the skin, a sensation of warmth, and severe itching or tingling. 

We love the sun. We complain about rainy days, and we look forward to summers at the beach. But we hate sunburns, wrinkled skin, and melanomas. All of those nasty things are the result of the ultraviolet rays that come with the warmth and light of sunshine. 

The predominant feature of Thomsen s disease is severe myotonia, worse in the cold and early morning than later in the day or in the warmth, unassociated with significant muscle weakness, degeneration, or other severe pathology. Myotonia is particularly common in ocular muscles, and muscles of the arms and legs. Onset is typically during childhood.
