Paving The Way For California's Asphalt Consumers

Written by Brett Lane

The California asphalt paving industry is ever-changing and in order to providerepparttar best services, asphalt paving companies are turning to new technologies to stay ahead ofrepparttar 136467 competition.

Asphalt technology in California has been changing sincerepparttar 136468 creation of Hot Mix Asphalt and will continue to change as time permits. Asphalt rubber pavement was introduced in 1991, which shocked many industry experts. Asphalt rubber pavement seemed promising to those inrepparttar 136469 industry who were ready for a change. Onrepparttar 136470 other end ofrepparttar 136471 spectrum were industry experts who thought thatrepparttar 136472 world wasn't ready for such technologies to be implemented.

In Tom Kuennens article titled, "Asphalt Rubber Makes a Quiet Comeback" shown in Better Roads Magazine, he describes rubber asphalt as, "a chemically reacted mix of liquid asphalt binder with 15 to 22% crumb rubber. The rubber is obtained from reclaimed tires, and added to liquid asphalt. It's reacted at elevated temperatures prior to being mixed with aggregate."

There are two types of asphalt rubber (wet process) are used in California. Type A- contains rubber only from ground tires, and Type B contains rubber from both ground tires and natural rubber. Caltrans seems to favor Type B binders because they have better resistance to reflection cracking and provide better stability. Rubber pavement disappeared for a few years due an increase in asphalt pavement technologies and a decrease in existing pavement costs associated with this form of material. Until recently, a number of important developments have helped propel asphalt rubber pavement to its current level of acceptance, including new tire-shredding technologies andrepparttar 136473 establishment of tire recycling facilities in every part ofrepparttar 136474 United States.

Stem Cell Breakthrough: Can You Now Make Your Own?

Written by David Lear

Overrepparttar past few years, stem cells have been getting a lot of attention. What makes them so interesting is their ability to stimulaterepparttar 136390 production of many types of healthy cells. That means that a single stem cell can turn itself into brain cells, liver cells, skin cells, pancreas cells, and so on.

In February of 2003, an article about stem cells was published inrepparttar 136391 Journal ofrepparttar 136392 American Medical Association (JAMA). A team of researchers at Johns Hopkins Medical Center reported, forrepparttar 136393 first time, that undifferentiated donor stem cells were able to crossrepparttar 136394 blood brain barrier and morph themselves into neuronal cells.

This was an especially important finding because, of allrepparttar 136395 cells inrepparttar 136396 body, neuron cells arerepparttar 136397 most advanced and complicated. This is significant because it means that if stem cells can morph themselves into brain neurons, then, chances are they can transform themselves into other types of cells too.

In a separate but related area of science, there is a growing body of evidence that a specialized area of nutrition called “glyconutrition” is very likely responsible for causingrepparttar 136398 body to manufacture its own stem cells from its own bone marrow. This research is being overseen by Dr. Reg McDaniel M.D. atrepparttar 136399 Fischer Institute.

Untilrepparttar 136400 JAMA article came out, Dr. McDaniel's team were in quite a quandary as to how people with varying neurological disorders such as Parkinson's, Alzheimer's, Children's Cerebral Palsy, Down's Syndrome, and Autism, were all experiencing increases in brain function when glyconutrients and other micronutrients were added to their diets.

Afterrepparttar 136401 initial discovery that stem cells stimulatedrepparttar 136402 growth of neuron cells, researchers wanted to know if these newly created neuron cells worked correctly. To do this, they turned their attention to children in comas. One was a boy who had been in a coma for three years. Glyconutrients were added to his feeding tube and within five days his doctor started seeing changes in his brain function.

All this is became even more noteworthy when it was discovered that this wasn't an isolated case. Other cases have been reported in which children have been awakened from long-term comas after receiving glyconutritional supplements introduced through feeding tubes.
