    AMERICA'S FIRST ASPHALT PAVEMENT
    July 29, 1870

    Was laid in Newark, N.J. Previously, coal tar was used for many pavements laid in the 1860s. The first recorded asphalt pavement in the U.S. was a sand mix placed in front of the City Hall in Newark, N.J., in 1870. Edmund J. DeSmedt, a Belgian chemist (who became the inspector of asphalt and cements for the District of Columbia) held a U.S. patent for this asphalt paving method, granted on 31 May 1867. In that century most roads, even in cities, were wide dirt pathways, severely affected by weather. Smooth surfaced asphalt roads originally were for the benefit of bicyclists. By 1904, only 141 miles were surfaced, but commonplace by 1916. Natural asphalt deposits were originally used, but almost all of the asphalt used commercially is now made from petroleum.

    THE FIRST IRON LUNG
    July 29, 1927 - United States

    (Electric Respirator) was installed at Bellevue hospital in New York for the post war polio epidemic. The first iron lung was developed at Harvard University by Phillip Drinker and Louis Agassiz Shaw built with two vacuum cleaners. The iron lung is a negative pressure machine which surrounds the patient's body except for the head, and alternates a negative atmospheric pressure with the ambient one, resulting in rhythmic expansion of the chest cage (and thus inhalation) in response to the negative extra thoracic pressure. During periods of ambient extrathoracic pressure, the lungs deflate. This type of machine is rarely used today.

ARTICLE INFORMATION :

Natural, safe ways to preserve dental health and oral hygiene.

ARTICLE CONTENT :

HOLISTIC DENTISTRY People often talk about preventative medicine and mention, quite rightly, the need for correct diet, exercise and certain nutritional supplements. But many pathogens and subsequent conditions can originate in the area of the mouth. Whilst the enzymes contained in the mouth's saliva are powerful enough to fight off many toxins, they cannot eradicate all unwelcome visitors. In addition, many people have amalgam fillings which contain mercury. If this mercury leaks into the body's system there can be a host of unpleasant consequences, the most common among them being Candida.

As mercury is essentially a poison, any presence of it in the blood can also increase the workload of the liver, which again may have a number of ramifications. Dentists who embrace a natural approach to oral hygiene and dental health are, in general, in the minority. The field of complementary medicine can provide a huge number of options for the dentist seeking to augment his approach and achieve a higher degree of efficiency. From homeopathy to natural detoxification products, most holistic dentists have found that introducing natural medicinal regimes into their practices has paid dividends.

One particular practice,in Bedfordshire, England, has been utilizing this approach now for almost twenty years. The Luton Holistic Dental Practice use everything from homeopathy to herbal formulas to augment their natural, mercury-free approach to dentistry. Their main dentist, Thomas Nyerges, says, 'We have noticed that recovery time and general response to treatment is remarkably improved when we include natural medicinal supplements as a part of overall treatment.'There are, additionally, numerous testimonials extolling the benefits experienced after mercury removal. Little by little other mainstream dentists are now also beginning to incorporate a more natural approach to treatment, good news for everyone who dreads those visits to the big leather chair!
