Filed under: Society — Tags: — Ralph C Dreher @ 1:55 AM

The Nobel prize achievers of 2013 in different categories were announced last month. These prizes are given by the Royal Swedish Academy of sciences annually in memory of Alfred Nobel to organizations and individuals who make significant contribution to Physics, Chemistry, Literature, Peace and Medicine.

Nobel Prize Winners, 2013 in Various Categories
Following are the 2013 Nobel prize winners in various categories:

1) Nobel Peace Prize
The 2013 Nobel Prize was given to The Organization for the Prohibition of Chemical Weapons OPCW based in Netherlands for its outstanding performance and efforts in eliminating chemical weapons. These global weapons help in deploying worldwide teams to identify if all the nations have signed the treaty are disclosing all the chemical weapons and if possessing them, destroying both the weapons as well as manufacturer sites.

2) Nobel Prize in Chemistry
This award was given to three scientist from US – Michael Levitt, Martin Karplus and Arieh Warshel for developing multi-scale computer models for complex chemical system. These computer can predict chemical reactions that are used in creating new drugs and other tasks. This approach was the combination of classical and quantum Physics.

3) Nobel Prize in Physics
Nobel prize in Physics 2013 went jointly to Francois Englert from Britain and Peter W Higgs from Belgium for Theoretical discovery of a mechanism which contributed to our understanding of the origin of mass of subatomic particles that also got recently confirmed by discovering the predicted fundamental particle through CMS and ATLAS experiments at CERN’s Large Hadron Collider.

4) Nobel Prize in Literature
The 2013 Nobel Prize in Literature was given to Alice Munro from Canada for mastering contemporary short story. She is 82 years old author, and is known for her famous stories like ‘The Moons of Jupiter’, ‘The Progress of Love’ and ‘Runaway’.

5) Nobel Prize in Physiology or Medicine
The 2013 the Nobel Prize in Medicine was given jointly to US based researchers, James Rothman, Randy Schekman and Thomas Suedhof for extensive efforts and work on the cell organizing its transport system. They helped in better understanding of tiny bubbles and vesicles that deliver cargo within a cell to right place and right time as any disturbance in this system can lead to neurological diseases, immunological disorders or diabetes.

6) Nobel Prize in Economics
The Nobel Prize in Economics was honored and shared between three Americans, Eugene Fama and Lars Peter Hansen from University of Chicago and Robert Shiller from Yale University for their performance of creating a deeper knowledge of how the prices in the market move.

The three economists have worked on methods that have been found useful in assessing the prices of financial assets over a period of time. They also have invented methods how price of financial assets can be measured. (more…)

Recent Advancements in Dental Technology

Filed under: 2013 — Tags: — Ralph C Dreher @ 6:10 AM

Dentistry is a field where technical advances happen continuously. This makes dentistry a challenging, exciting and a rewarding profession. Advancements and new technologies in dental field make dental procedures more comfortable, efficient and durable. In this article, we will discuss in this article the recent developments in dental technology.

Recent advancements in Dental Technology

Dental lasers/Diagnodent
Diagnodent is a new technology for detecting cavities early. It makes use of laser technology for identifying and detecting early signs of cavities/tooth decay. Some of the hidden cavities can be detected with the help of this tool, which sometimes x-rays might not show up in results clearly. Diagnodent enables dentists to perform treatment in its early stage.

Intra oral camera
Using intra oral camera, a clear picture of inside of the mouth is made visible to the patient. These cameras create high quality images. The images are used to give a clear state of oral health. It helps in building trust through visual communication.

Air abrasion
Air abrasion helps in removing the decayed tooth without anesthesia. Moreover, it can help remove old filling in the tooth but metallic restorations like amalgam fillings can’t be removed with the help of air abrasion.

Digital x-rays
This is one of the latest developments in dentistry. Many dentists are switching to digital x-rays, as these x-ray instruments give more accurate image and better results than traditional x-rays instruments do. Digital x-ray machines make use of digital technology rather than a film. Then the images are directly sent to the computer instead getting it developed in a dark room.

CT scans
CT scans are now used in modern dentistry. Dentists use this scan when performing implant surgery to view jawbone. This scan helps the dentists give the exact image when placing restorative devices. Sometimes, CT scans are used for the patients having impacted tooth, thus help in determining appropriate course of treatment.

Sedative dentistry
In modern dentistry, oral sedation is replacing traditional method of numbing the mouth. In this type of sedation, no needles are used. There are three types of sedation used:

  • Oral sedation
  • Inhalation sedation
  • Intra venous (IV) sedation

Oral sedation is easily administered. It requires swallowing a pill. In inhalation sedative method, a small mask that supplies oxygen and nitrous gas is placed on the nose throughout the treatment. After the treatment is completed, nitrous oxide is turned off and just oxygen will be supplied till the patient feels completely normal.

IV sedation is given through veins. As IV sedation has quick effects, many patients prefer for this kind of sedation.

Field of dentistry has come a long way from the use of traditional and manual dental instruments to more advanced and computerized equipment. These advancements are likely to help dentists do their job more efficiently, and are equally likely to benefit people with dental issues. (more…)
