Breaking teeth

A method of assuring nearly perfeet tooth eontaet is to mateh-lap the gear teeth after nitriding. Lapping eliminates the break-in period, whieh otherwise takes from 70 to 120 hours. It is during the break-in period, that tooth surfaee distress usually oeeurs. 

Sodium carbonate peroxide is added to peroxide toothpaste as a whitener. It breaks down into sodium carbonate (washing soda) and hydrogen peroxide. The hydrogen peroxide bleaches the teeth and kills germs. 

Adhesiveness, defined as the work necessary to overcome the attractive forces between the surface of the sample and the surface of other materials with which the food comes into contact, e.g. tongue, teeth, palate, etc. (Szczesniak, 1963), is given on the texturometer curve by the negative force area, representing the work needed to pull out the plunger from the sample. This parameter s value may be considered an evaluation of stickiness of jelly. Fracturability, also called brittleness, is given by the measure (%) of the plunger path into the jelly when it breaks. 

Plastic acrylic denture teeth are made by injection or transfer molding. Acrylic teeth have a higher strength than porcelain teeth and break less readily. However, they resist cold flow, have greater water absorption, and have higher wear rate than porcelain teeth. 

By convention, numbers, 9 or less and all numbers at the start of a sentence are written in letters, while numbers of 10 and above are written as figures. Rules, however, are made to be broken. Figures are read more easily and quickly than words, particularly by nonnative English speakers, so a case can be made to break this rule (even if it does cause grinding of the teeth by some purists). An acceptable compromise maybe to use figures in the study plan (which needs to be easily and rapidly understood by the technicians) and letters in the report text. 

There is a truism athletes face often without realizing it. You are what you absorb, not just what you eat. When you eat whole /complete protein source food such as round steak, your teeth grind up the fibers into smaller pieces. If you do not chew your food, digestive enzymes /juices fail to access enough area of these fibers to fully break them down. Less area exposed, less digestion, less amino acids to supply growth and repair. 

Figure 9.11 Diagram of a Bauer attrition mill. Configuration shown is used for fine milling degerminated residue. With wider spacing of interlocking teeth and no impact ring, it is used for degermination (first-break) milling.

Small amounts of silver are used in a variety of other products. For example, it is used in dental amalgams. An amalgam is an alloy in which mercury is one of the metals used. Silver amalgams work well for filling decayed teeth. They are non-toxic and do not break down or react with other materials very readily. Silver is also used in specialized batteries, cell phone covers, circuit boards, and Radio Frequency Identification Devices (RFIDs). 

This brings to mind a classic news account of a rape, sfere the word rape was in comrron use. IIe beat her up, zeeked her teeth out, threw her downstairs, breaking her g, and then attacked her . 

Approximately 30-40% of snake species produce some type of buccal toxins or venom. The major adaptive functions of venoms and buccal toxins in snakes have been associated with food acquisition, defense, and predigestion of prey items. Venomous species possess specialized structures (venom glands or Duvernoy s glands), which produce venom or toxins and enlarged teeth or fangs, which inject or introduce the venom into the prey item. Venom contains enzymes and proteins that break down cellular structures and interferes with critical functions such... 

The first MDF was made using particleboard equipment. The fibre was dried and mixed with resin in a particleboard blender. The product had excellent properties, but there were dark areas of varying sizes in the panel that on analysis were shown to have a resin content two or three times the average. These clumps of resin-rich fibre - known as resin spots - were sometimes sufficiently hard as to break saw teeth or to form lumps under overlays. A range of techniques was adopted to break up these lumps, including attrition mills, but with limited success. 

Zinc is in each of the following enzymes and plays an important part in the enzyme function. Alcohol dehydrogenase detoxifies alcohol. Carbonic anhydrase deposits calcium on bones and teeth. Carboxypeptidase breaks down proteins. Zinc activates an RNA-synthesizing enzyme and is a cofactor for the enzymes that make and break down collagen.
