profiles are encrypted sets of numbers that reflect a person’s DNA makeup‚ which can also be used as the person’s identifier. DNA profiling should not be confused with full genome sequencing. It is used in‚ for example‚ parental testing and rape investigation. Although 99.9% of human DNA sequences are the same in every person‚ enough of the DNA is different to distinguish one individual from another. DNA profiling uses repetitive ("repeat") sequences that are highly variable called variable number

An Exploration of the investigations used to diagnose stroke Methods Used to Diagnose a stroke There are many different tests that can be carried out to help diagnose a stroke. The main way in which they are found is by using brain imaging so that they are able to pick up any visual issues. Brain imaging allows the doctors to understand whether the stroke was ischemic or hemorrhagic. It also allows them to determine how severe it was. Those who have suffered from a stroke must have a brain scan within

Medieval Catapult Investigation I decided to think outside the box for this assignment and have the mindset to try and create a model of a medieval catapult for not only the enjoyment of building it but the understanding of what it was like to live in an era before technology‚ electricity‚ advanced tools and appliances. Trying to figure out what these times were like I tried to create my model to mimic methods used in this era using recycled hard wood‚ soft wood and twine to create an aged look

Contamination can occur by either the number of personnel at the scene or the environmental conditions. When dealing with a death investigation it might be hard to prevent the amount of personnel. The first ones to arrive on the scene would be the first responders‚ along with paramedics‚ then followed by the investigators‚ coroner or medical examiners‚ at times the prosecuting attorneys
