Removable part

These should be operated 50 times and removable parts inserted and withdrawn 25 times each. 

The interlocks should be set in the intended position to prevent operation of the switching device and insertion or withdrawal of the removable parts. Fifty attempts must be made to operate the switching device and removable parts inserted and withdrawn 25 times each. 

Multi-fuel operation with coal-firing equipment is more difficult to achieve, partly because the grate obscures some of the boiler heating surfaces and partly due to the volume that it also occupies. Systems do exist for this requirement, but changeover is not as instant as oil and gas, as it is normally necessary to remove part of the coal-firing equipment. 

All electrical energy fed to the room will appear as heat. This presents a load to the plant unless power is conveyed out of the room by cable or hot items are physically removed. Parts of some large computers are cooled by a direct supply of chilled water presenting a load on the refrigeration plant but reducing the load on the airside. Cold outside conditions will result in some of the internal load being met by fabric loss. 

An early effort using this approach in Guinea-pigs reported variable results — attributable to incomplete nerve sectioning (Planel, 1953). Sectioning procedures may also produce some unwanted effects as intracranial nerve section will remove part of the animal s N. terminalis sensory capability (Devitsina and Cherova, 1992). 

The best known application of PCMs for transport or conservation of materials at a constant temperature are containers with removal parts containing a PCM (usually water, nowadays many other products) that must be kept in the refrigerator before use, and that keep a low temperature in the container for a period of time (Figure 161). 

In fact, the availability of the stream with a concentration below the environmental limit, removes part of the... 

A water-alone monolayer potential above the pzc is in accordance with an absolute work function measurement for the water monolayer on Pt(lll) of 4.8 eV (29). Comparing this to the hydrogen electrode (4.7 eV below vacuum (30) for the normal hydrogen electrode NHE) corrected by 7x0.059 V for a nominaI pH 7 yields a water-alone mono-layer potential of +0.5 V vs. RHE at pH 7. This lies 0.3 V above our proposed pzc of 0.2 V RHE. This relatively high apparent potential of the water monolayer has been noted previously (Sass, J.K., private communication), and has raised concern about the relevance of the UHV monolayer to real electrochemical conditions, since most electrochemical measurements of the pzc of polycrystalline Pt have been closer to 0.2 V than to 0.5 V (31). By showing that the water monolayer lies above, not at, the pzc, the present H.+H-O data remove part of the apparent discrepancy between the electrochemical and UHV results. If future UHV work function data show a large ( 0.3 V) decrease in the water monolayer work function upon addition of small (<20X saturation) amounts of hydrogen, all of the apparent discrepancy could be quantitatively accounted for. 

In the manufacture of Labneh and other Middle Eastern fermented milks, the fermented product is concentrated by removing part of the serum (whey). This was done traditionally by stirring the yoghurt and transferring it to muslin bags to partially drain. Concentration can now be achieved by ultrafiltration, before, but preferably after, fermentation. 

Purification of Ammonium (Sodium, Potassium) Chloride. Prepare a saturated solution of ammonium chloride at 60 °C, taking 50 ml of water and the calculated amount of salt for this purpose. Heat the solution almost to boiling, filter it through a funnel for hot filtration, pour the filtrate into a porcelain bowl, put it on a water bath, and evaporate it up to half of the initial volume. Why is it necessary to remove part of the water by evaporation in this experiment ... 

D) pH value. Cool the filtrate from opn C to RT, transfer it to a 1000ml volumetric flask and dilute to the mark. Remove part of soln and det its pH by means of a standardized pH meter... 

A conceptually simple way of changing surface properties is to remove parts of it. These methods are summarized as etching techniques [407,444], In particular in microfabrication etching techniques are essential. Etching techniques are characterized by several properties ... 

Chocolate has antioxidant properties for low-density lipoproteins and hence could prevent heart disease. Foods and beverages derived from cocoa beans have been consumed by humans since 460 a.d. Cocoa pods from the cocoa tree (Theobroma cacao) are harvested and the beans removed and fermented. Dried and roasted beans contain about 300 chemicals including caffeine, theobromine, and phenethylamine. Chocolate liquor is prepared by finely grinding the nib of the cocoa bean and is the basis for all chocolate products. Cocoa powder is made by removing part of the cocoabutter from the liquor. Bittersweet chocolate, sometimes called dark chocolate, contains between 15 and 60% chocolate liquor, the remainder being cocoa butter, sugar, and other additives. Milk chocolate is the predominant form of chocolate consumed in the U.S. and typically contains 10 to 12% chocolate liquor. 

As well as their function in binding to antigen, immunoglobulins have other roles within the immune system that necessitate interactions with other proteins such as those of the complement and phagocytic systems. In techniques such as immunofluorescence or in in vivo applications, these interactions can be problematic but can be solved by the use of selective proteolysis to remove parts of the molecule. The polypeptide chains making up the IgG molecule... 

The problem with working with separatory funnels is that the separation is generally not complete. Each component has an equilibration concentration in each layer. If we were to draw off the bottom layer and dry it to recover the red dye, we would find it still contaminated with the other component, the blue dye. Repeated washings with fresh lower layer would eventually leave only insignificant amounts of contaminating red dye in the top layer, but would also remove part of the desired blue compound. Obviously, we need a better technique to achieve a complete separation. 

The question of the contribution of the benzene rings to the indigo chromogen led to a search for the basic chromophore. Consecutively removing parts of the mesomeric system leaves a cross-conjugated structure 7 that, as the basic chromophore, still exhibits the typical deep color and redox properties of indigo.

Gases that are used in a polyurethane factory include nitrogen, butane, or LPG for heating, and oxygen and acetylene for welding. Compressed air is used to remove parts from molds and can be generated on site with a small compressor. 

Another example is the injection moulding of a pail, where the injection takes place at the bottom. The most removed part, the brim of the pail, will solidify first, thus impeding the shrinkage of the remaining part, in particular of the bottom. The bottom is, therefore, heavily stressed and may spontaneously break in shock loading. A better construction of the mould can prevent this drawback, namely by making the bottom not flat but somewhat hollow, so that the stresses easily disappear by a minor deformation of the bottom. 

Although the lifetimes are equal, the induced redistribution of the energy removes part of it from the initially excited state, producing the fluorescence quenching. Its relative quantum yield is... 

Aside from the expression of histidine mutations that are easily detected, other properties have been built into the Salmonella strains by mutation to increase their sensitivity. The strains cure defective in DNA excision repair (uvrB). In this case, the increased sensitivity probably is due to the failure to remove some DNA adducts that could lead to mutation. The strains also possess a mutation (rfa) that removes part of the lipopolysaccharide barrier of the bacterial cell wall and thereby makes the cells more permeable to some chemicals. Finally, Salmonella strains TA98 and TA100 contain the R-factor plasmid pkMIOl,277 which increases sensitivity probably by increasing the activity of an error-prone DNA-repair system.
