Tannin-containing woods can also suffer from dark-brown stains produced by alkali, usually from a concrete or a detergent source. Conversely, fair-faced concrete can be similarly stained by the run-off water from unprotected hardwood surfaces. Some woods, e.g. afzelia, ayan and idigbo, give yellow contaminating dyes with alkaline detergents and should not be used in washrooms and kitchens. 

Many bacteria perform services we find useful and even necessary, although we rarely take note of them. Some bacteria participate in the decomposition of dead plants and animals and so help recycle chemicals that are otherwise locked away from the living world. Some are sources of antibiotics that have revolutionized the treatment of infectious disease in the past fifty years. Others are responsible for nitrogen fixation, converting relatively inert atmospheric nitrogen into biologically useful ammonia—a conversion that is not simple in the chemical laboratory. Still other bacteria are indispensable in the world s kitchens, for without them there would be no cheese or yogurt, nor any of hundreds of other traditional milk products. We could not enjoy pickles or sauerkraut, and...

At the same time that gifts of natural foods mark and cement relationships between close friends and relatives, they also illuminate a more profound set of relationships between nature and people. In this relationship, nature becomes personified as the caretaker, nurturer, and provider of the people who inhabit it. A conversation among several of luliia s closest friends in the Nadezhda community captures these sentiments beautifully. The conversation took place while we were seated around the tiny table in luliia s dacha kitchen, enjoying her freshly baked blueberry pastries, freshly picked tomatoes and cucumbers, tea, and other snacks.

BY NOW THE fair had ended, and the village street beyond my room was quiet except for the occasional flurry of conversation, the movement of sheep or goats, the squabble of hens, and the insistent striking of the clock. Meanwhile, they were still bottling fruit in the kitchen, and I was half stifled by the smell of boiled sugar.

Compared with other subjects, chemistry is commonly believed to be more difficult, at least at the introductory level. There is some justification for this perception for one thing, chemistry has a very specialized vocabulary. However, even if this is your first course in chemistry, you already have more familiarity with the subject than you may realize. In everyday conversations we hear words that have a chemical connection, although they may not be used in the scientifically correct sense. Examples are electronic, quantum leap, equilibrium, catalyst, chain reaction, and critical mass. Moreover, if you cook, then you are a practicing chemist From experience gained in the kitchen, you know that oil and water do not mix and that boiling water left on the stove will evaporate. You apply chemical and physical principles when you use baking soda to leaven bread, choose a pressure cooker to shorten the time it takes to prepare soup, add meat tenderizer to a pot roast, squeeze lemon juice over sliced... 

Catalytic or flameless combustion of hydn en exhibits many advantages in comparison with flame combustion. It occurs at low temperatures (ambient - 800 K), is safe and leads to a very high conversion of the burning gas (99.9 %). The NOX formation which usually occurs in conventional combustion at temperatures of about 1700 K, is here almost completely suppressed. The catalytic combustion in diffusion burners (Fig. 7-2) occurs in the presence of small amounts of Pt or Pd catalysts. It is adequate, e.g., for kitchen appliances such as cooker, oven, water heater, space heater. Drawbacks are the possible non-uniformity of the temperature distribution at die catalyst surface, rapid changes in the operational state, and relatively small heat flux densities [47]. 

Wohler tells an amusing story of Berzelius s conversion to Davy s theory. In 1823 he was working in Berzelius s kitchen-laboratory and the cook, Anna Sundstrom, cleaning some apparatus, remarked that it smelt of oxymuriatic acid. Berzelius, to the surprise of Wohler, said Listen Anna, you must not say oxymuriatic acid any more, you must say chlorine that is better. ... 

For a variety of reasons, in part convenience and in part dietary preference, the conversion of oils to fats has become a major industry. The process is called hardening of oils and involves die catalytic reduction (Section 5.8) of some or all of an oil s carbon-carbon double bonds. In practice, the degree of hardening is carefully controlled to produce fats of a desired consistency. The resulting fats are sold for kitchen use (as Crisco , Spry , and others). Margarine and other butter substitutes are produced by partial hydrogenation of polyunsaturated oils derived from corn, cottonseed, peanut, and soybean oils. To the hardened oil are added )3-carotene (to give it a yellow color and make it look like butter), salt, and about 15% milk by volume to form the final emulsion. Vitamins A and D may be... 

While fixing sausage in the kitchen—the guts are cleaned and sticks are pushed through them to turn them inside out, long rods—a conversation came up in the kitchen.
