Disaster victim identification is an important aspect of forensic odontology. Check them out! In the following videos, Dr David Sweet from the University of British Columbia will share about the role of a forensic dentist in identifying victims to bring closure to a case. Check out these interesting videos! The truth on how the victims are identified after a plane crash. In the article it is stated that usually using the fingerprint you can find the answer to most of the cases but when it comes to a plane crash it is not the best way as the fingerprints are usually lost. Thus, the bones comes in place in the invesrigation. There are many ways in identifying the age of a person. It will be a big help to investigation if ethnic origin of the death can be identified. Human teeth differ by little between ethnic groups.

Age Estimation in Forensic Sciences. PubMed Central. Alkass, Kanar; Buchholz, Bruce A. Age determination of unknown human bodies is important in the setting of a crime investigation or a mass disaster because the age at death, birth date, and year of death as well as gender can guide investigators to the correct identity among a large number of possible matches. Traditional morphological methods used by anthropologists to determine age are often imprecise, whereas chemical analysis of tooth dentin, such as aspartic acid racemization, has shown reproducible and more precise results.
In this study, we analyzed teeth from Swedish individuals using both aspartic acid racemization and radiocarbon methodologies.
Tool Kit for Deciphering the Microscopic Archaeological The reality. 10 Amino acid racemization dating Level 6: The whole dentin component of the tooth.
Age estimation remains one of the most challenging tasks in forensic practice when establishing a biological profile of unknown skeletonised remains. Morphological methods based on developmental markers of bones can provide accurate age estimates at a young age, but become highly unreliable for ages over 35 when all developmental markers disappear. This study explores the changes in the biomechanical properties of bone tissue and matrix, which continue to change with age even after skeletal maturity, and their potential value for age estimation.
As a proof of concept we investigated the relationship of 28 variables at the macroscopic and microscopic level in rib autopsy samples from 24 individuals. This method outstrips all existing age-at-death methods based on ribs, thus providing a novel lab based accurate tool in the forensic investigation of human remains. The present application is optimised for fresh uncompromised by taphonomic conditions remains, but the potential of the principle and method is vast once the trends of the biomechanical variables are established for other environmental conditions and circumstances.

First described more than two decades ago, microwave-assisted organic synthesis has matured from a laboratory curiosity to an established technique that today is heavily used in both academia and industry. One of the most valuable advantages of using controlled microwave dielectric heating for chemical synthesis is the dramatic reduction in reaction times: from days and hours to minutes and seconds.
As will be explained in this tutorial review , there are many more good reasons why organic chemists are nowadays incorporating dedicated microwave reactors into their daily work routine.

Establishing a baseline of natural climate variability over decade-to-century time scales requires a perspective that can be obtained only from a better knowledge of past variability, particularly that which precedes the pre-industrial era. Information revealing these past climate conditions is contained in historical records and “proxy” indicators.
The historical records of climate other than systematic weather observations, which began in the late s , while invaluable because of their scope and often uniquely relevant perspective, are usually limited to the last several hundred years see Chapter 2. The proxy indicators represent any piece of evidence that can be used to infer climate. Typically, proxy evidence includes the characteristics and constituent compositions of annual layers in polar ice caps, trees, and corals; material stored in ocean and lake sediments including biological, chemical, and mineral constituents ; records of lake levels; and certain historical documents.
Such proxy indicators can provide a wealth of information on past atmospheric compositions, tropospheric aerosol loads, volcanic eruptions, air and sea temperatures, precipitation and drought patterns, ocean chemistry and productivity, sea-level changes, former ice-sheet extent and thickness, and variations in solar activity—among other things. These records are particularly appropriate for detecting three manifestations of climate variability:.
