Whereas Hannay used a flame-heated tube, Moissan applied his newly developed electric arc furnacein which an electric arc was struck between carbon rods inside blocks of lime. The contraction generated by the cooling supposedly produced the high pressure required to transform graphite into diamond. Moissan published his work in a series of articles in the s.

Add another 15 varieties to the growing list of recalled pet foods. The company said it took that action late Friday after tests revealed traces of a melamine derivative in the Chinese rice protein concentrate the company received from its supplier, Cereal Byproducts of Illinois. Cereal Byproducts on May 4 recalled the rice protein concentrate it received f Nestle Purina PetCare Co.

The company said some of the cans might be contaminated with melamine, the toxin suspected of causing the pet illnesses. No dry products are involved. No cat products are involved. One of my dogs is currently in the hospital because her kidneys are failing.

Sophie is only 6 months old and is very ill," she told ConsumerAffairs. This has caused me a great deal of stress, time off work, money and possibly the lives of my animals. Joanne of Bentleyville, Penn. When her cat refused to eat the Iams Select Bites pouches Joanne brough home, she let her border collie eat them.

The dog died a slow death from kidney failure. The following day I tried the food again with the cat but again he would not eat it so again I gave it to the dog. I had no idea that I thought the food was a treat for my dog was actually poison.

I feel I poisoned one of my family," Joanne said in a complaint to ConsumerAffairs. I will never do that again. The food included wheat gluten from the same supplier that Menu Foods used. The Food and Drug Administration -- and an outside laboratory -- announced on Friday that tests found a chemical called melamine in samples of the tainted pet foods involved in the recall.

Cornell University officials also confirmed they found melamine -- used in floor tiles, kitchenware, and fire retardant fabrics -- in the urine and kidney of a sick cat.

Henderson said the melamine-tainted wheat gluten came from a new supplier, who imported the ingredient from China. We continue to engage in the highest levels of monitoring and testing in the pet food industry. These tests will be expanded as a result of this experience. The federal agency is now investigating whether that contaminated ingredient was used to make any dry pet foods.

When asked if pet owners could be feeding unsafe food to their animals, Sundlof said: My sense is that we have gotten most of it under control.

But the FDA said its tests -- and those by the outside lab -- did not reveal the rat poison in the recalled pet food.

Or in the wheat gluten. The FDA said today that it has found no indication the contaminated ingredient is in any food humans eat. The agency said it would alert the public if it found melamine in any other foods.

The FDA said it has received calls from more than 8, veterinarians and pet owners. The majority of those deaths -- 88 -- involved cats. The remaining five deaths did not list a species. In addition, VIN said its members have seen cases of kidney failure since Menu Foods announced its massive recall on March 16, The Web site PetConnection.

Veterinarians, however, warn that animals do not show symptoms until about 70 percent of the kidney function is lost. Hood, president of ConsumerAffairs.

The person, who spoke on the condition of anonymity because he or she was not authorized to talk to the media, said the investigation could be civil or criminal in nature. Earlier this week, a consumer in Evansville, Ind.

A urinalysis is a group of physical, chemical, and microscopic tests. The tests detect and/or measure several substances in the urine, such as byproducts of normal and abnormal metabolism, cells, cellular fragments, and bacteria..

Urine is produced by the kidneys, two fist-sized organs located on either side of the spine at the bottom of the ribcage.

A synthetic diamond (also known as an artificial diamond, cultured diamond, or cultivated diamond) is diamond produced in an artificial process, as opposed to natural diamonds, which are created by geological processes.

Synthetic diamond is also widely known as HPHT diamond or CVD diamond after the two common production methods (referring to the high-pressure high-temperature and chemical.

In contrast to research using biochemistrygeneticsor molecular biologywhere mutagenesis can provide a new version of the organism, cell, or biomolecule of interest, chemical biology probes systems in vitro and in vivo with small molecules that have been designed for a specific purpose or identified on the basis of biochemical or cell-based screening see chemical genetics.
