Polished white

The polished white rice that is an important staple food for a large section of the human population is obtained by milling paddy rice. It is first dehulled to yield the following fractions (approximate proportions in parentheses) brown rice (80%) and hulls (20%). The brown rice is then milled to yield rice... 

The problem of the Holocaust Survivor Syndrome received international attention at the time of the Wuppertal trial. Medical sources told me that the Ukrainian-American psychiatrist Dr. 0. Wolansky was one of the leading experts on this subject today, and I was referred to a seminar he had given on this subject on January 25, 1993, at a Congress held in the Polish Consulate in New York and attended by 150 Polish, White Russian and Ukrainian physicians. To quote an excerpt ... 

Figure 23B presents IR transmission spectra for (5) an optically pure and mechanically polished white diamond disc, (6) an undoped and polished (both sides) Si substrate, and (7 and 8) moderately and heavily boron-doped microcrystalline diamond thin films deposited on the undoped Si. The white diamond is relatively free of structural defects and chemical impurities. There is reduced transparency between 2500 and 1500 cm due to the two-phonon absorption. Diamond films with more... 

FIG. 23. Transmission spectra for different materials in the (A) UV/Vis and (B) IR regions of the electromagnetic spectrum. The electrodes in (A) are (1) a thin film of ITO on quartz, (2) a thin film of boron-doped nanocrystalline diamond on quartz, (3) a thin film of mechanically polished and boron-doped diamond on an optically pure, white diamond substrate, and (4) a free-standing, boron-doped, and mechanically polished diamond disc. The electrodes in (B) are (5) an optically pure and mechanically polished white diamond disc, (6) an undoped and polished (both sides) Si substrate, and (7 and 8) moderately and heavily boron-doped microcrystalline diamond thin films deposited on the undoped Si.

Polished white rice is made from this cleaned rice by additional treatment of the kernels with talc (a magnesium silicate) and 50% glucose solution. This imparts a glossy, transparent coating to the kernels. 

Dr. Eijkman then began a series of experiments that led to the first clear concept of disease due to nutritional deficiency. He fed polished white rice to chickens, pigeons, and ducks. They developed the paralysis that he had observed previously, then recovered when he fed them natural (unmilled) rice. Birds fed whole rice remained well. 

Sake or rice wine is a noncarbonated alcoholic beverage widely consumed in Asia, mainly Japan. This alcoholic spirit contains from 14% to 16% ethanol and is produced from refined rice. In Japan alone, more than 1.5 million kiloliters of sake is produced annually (Yoshizawa and Kishi 1987). For sake production, four basic raw materials are used refined polished white rice water an Aspergillus oryzae culture, commonly known as Koji-kin and yeast. 

White rice Rice obtained after dry milling of rough rice. The paddy rice is first dehulled, and the resulting brown rice is next decorticated and polished. White rice is free of glumes, pericarp, germ, and the alenrone layer. It basically consists of starchy endosperm. 

CoAsS, are also used as sources. The ore is roasted and Co is precipitated as the hydroxide and then reduced to Co with carbon (hep below 417 - C, cep to m.p.). The metal is silvery white and readily polished. It dissolves in dilute acids and is slowly oxidized in air. Adsorbs hydrogen strongly. The main use of cobalt is in alloys. Cobalt compounds are used in paints and varnishes, catalysts. Cobalt is an essential element in the diet. World production 1976 32 000 tonnes metal. 

Nickel is silvery white and takes on a high polish. It is hard, malleable, ductile, somewhat ferromagnetic, and a fair conductor of heat and electricity. It belongs to the iron-cobalt group of metals and is chiefly valuable for the alloys it forms. 

As vitamin Bg is mainly located in the germ and aleurone layer in cereal grains polishing for the production of flour removes a substantial portion. White bread is therefore a poor source unless fortified. Some nonedible yeasts contain up to 38 mg/100 g dry weight vitamin B, the highest level of the natural sources (4,27). As a rule, these amounts are too low for cost-effective isolation. 

Tin oxide is a pure white powder. Mixed with water, glycerol, or alcohol into a paste, it is used for polishing teeth and metallic restorations.

Glass-reinforced aluminum foil with either a bright polished or white lacquer surface is utilized with most types of insulant. Primarily it is used as a vapor control layer or as a means of upgrading the fire properties of plastic foams, but it does give a semi-decorative finish to the insulation. It is therefore often use where the insulation is open to view but located away from direct risk of mechanical damage. 

The key properties here are hardness and wear resistance, ability to. stand minor knocks and dents without cracking and resistance to various domestic chemicals. These vary with type of appliance, e.g. detergent solutions are important for washing machines, while a fridge will be required to withstand fruit juices, ketchup and polishes. Good colour and appearance in white and mainly pastel shades will be expected. Corrosion resistance is required, especially for washing machines, and domestic appliances frequently have to withstand humid conditions in kitchens. 

Elder has a hard white wood that is resilient yet easy to hollow out. Carpenters have long employed it, enjoying its close grains and the fact that it polishes easily. The wood has a pleasant musky smell. The wood has also been used for fishing rod parts, fishing floats, needles for net weaving, shoemaker s pegs, combs, bows, skewers and small toys.
