DIET TECHNOLOGY, HOW TO MAINTAIN YOUR BODY BY DAILY DIET.


                         Investigators need to date objecLSO understand what happened around them and when it happened It also helps in understanding a particular object was used. Such investigations are taken by scholars studying historical civilizations, rocks, ancient cultures or crime investigators etc. Many techniques are used in various ancient natural objects and artifacts. Various methods are based on radioactivity One method is radiocarbon dating Radiocarbon, or Carbon 14, is a form of the element. It is unstable and weakly radioactive, The stable forms are Carbon 12 and Carbon 13.


                       Carbon 14 constantly takes form and then changes in the upper atmosphere. Plants and animals take in Carbon 14 whole their lifetimes. When they die, they stop exchanging Carbon and their Carbon 14th start to decrease ata rate determined by the law of radioactive decay. This method is designed to measure this leftover radioactivity. By knowing how much Carbon 14 is left in a sample, the age of the organism, when it died, can be known as archaeo magnetic dating. This is the name of the Earth Tree ring dating is another useful technique Every year changes occur within a tree by factors like ne rain, etc. These changes could be seen in form of ring patterns in the tree trunks, These techniques used in a date fingerprint in this technique.


SUSPECT IDENTIFICATION:- 

                 Whether you watch detective serialin TV, you must have seen DNAs samples being YESerialin TV, you must have seen DNA samplesbeing Imatched. What is ths dna analysis: And why do TV shows find it interesting and effective to use? Fictional characters like Father Brown, Sherlock Holmes and Byomkesh Bakshi have become famous for their skills in identifying criminals without any technology. But today, investigators rather use loESOTHE * technologies to detect culprits The most popular and accurate of them are DNA analysis.


                        DNA is the most basic biological content that every human has has. Every cell in a human being has thousands of DNA strands This DNA is unique Every person has a unique 'DNA fingerprint. This fingerprint can be identified using any available evidence like blood, saliva, etc. Even a single hair is sufficient to identify the DNA fingerprint. It is transferred on sheets in form of barcode patterns Police use these to match them to the suspects. DNA can not be faked. Therefore, it is the most scientific and effective instrument to use in identifying suspects. That's why investigators prefer using this technique Other effective methods are also used in suspect identification. Photo composites arecreated using special software Physical Evidences Bite marks are also useful in identifying the culprits using their dental records.
