Relevance and Future Significance to Forensic Sciences: M-Vac is a valuable tool to forensic investigators as it can dramatically improve the chance of generating a DNA profile. This makes it particularly relevant and valuable to forensic scientist. While there are already promising research studies conducted on this technology, further research on M-Vac is necessary to demonstrate its effectiveness as well as make it more popularized in society. While researchers are already beginning to move towards the M-Vac ways of conducting investigations, it is necessary that more research be conducted on this product to ensure that investigators know that this product is available to them and effective. Also, developing innovative research on this tool
. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique, there has been a large number of individuals released or convicted of crimes based on DNA left at the crime scene. DNA is the abbreviation for deoxyribonucleic acid.
Nowadays, DNA is a crucial component of a crime scene investigation, used to both to identify perpetrators from crime scenes and to determine a suspect’s guilt or innocence (Butler, 2005). The method of constructing a distinctive “fingerprint” from an individual’s DNA was first described by Alec Jeffreys in 1985. He discovered regions of repetitions of nucleotides inherent in DNA strands that differed from person to person (now known as variable number of tandem repeats, or VNTRs), and developed a technique to adjust the length variation into a definitive identity marker (Butler, 2005). Since then, DNA fingerprinting has been refined to be an indispensible source of evidence, expanded into multiple methods befitting different types of DNA samples. One of the more controversial practices of DNA forensics is familial DNA searching, which takes partial, rather than exact, matches between crime scene DNA and DNA stored in a public database as possible leads for further examination and information about the suspect. Using familial DNA searching for investigative purposes is a reliable and advantageous method to convict criminals.

Once a crime has been committed the most important item to recover is any type of evidence left at the scene. If the suspect left any Deoxyribonucleic acid (DNA) at the crime scene, he could then be linked to the crime and eventually charged. A suspect’s DNA can be recovered if the suspect leaves a sample of his or her DNA at the crime scene. However, this method was not always used to track down a suspect. Not too long ago, detectives used to use bite marks, blood stain detection, blood grouping as the primary tool to identify a suspect. DNA can be left or collected from the hair, saliva, blood, mucus, semen, urine, fecal matter, and even the bones. DNA analysis has been the most recent technique employed by the forensic science community to identify a suspect or victim since the use of fingerprinting. Moreover, since the introduction of this new technique it has been a la...

Section 8 of the Safety, Health and Welfare at Work Act (2005) puts requires safe systems of work to be developed by the employer. Section 19 of the Act requires the employer to conduct a risk assessment of work activities, including infectious diseases and Schedule 3 of the Act provides the general principles of prevention to ensure the safety of employees in the workplace. The Safety, Health and Welfare at Work (Biological Agents) Regulations require that where vaccines are available, employers must offer vaccination, free of charge, to employees who are at risk of occupational exposure to biological agents such as TB.

Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
Forensic science has paved the way to a new world of technological advancements in solving crime, through DNA analysis, new technology such as M-Vac, improving systems such as CODIS and other investigative methods. As forensic science technology advances, the chance of an individual being able to commit a crime and walk away free without leaving any trace of evidence will lessen. While forensic science has its limitations, it can be the only way to provide an accurate account of what actually occurred at some crime scenes.
Forensic science has now been recognized as an important part of the law enforcement team to help solve crimes and cold cases. The advances in technology are being used each day and we must continue to strive to develop better advances in this field. The recent discovery of using DNA in criminal cases has helped not only positively identify the suspect, but it has helped exonerate hundreds of innocent individuals. “With new advances in police technology and computer science, crime scene investigation and forensic science will only become more precise as we head into the future.” (Roufa, 2017) Forensic science and evidence helps law enforcement officials solve crimes through the collection, preservation and analysis of evidence. By having a mobile crime laboratory, the scene gets processed quicker and more efficiently. Forensic science will only grow in the future to be a benefit for the criminal justice
The process of gathering evidence largely depends on the role of discretion by the police. Once police have decided to pursue a reported crime, they then begin the process of gathering evidence. To ensure that the process of gathering evidence is lawful, the police must follow the procedure outlined in the Evidence Act 1995 (NSW), which describes the manner in which evidence can be collected. This act imposes certain limits on the way police can gather evidence and the types of evidence that can be used. The Act is able to protect the rights of citizens by making it a requirement for the police to gain necessary legal documentation, such as search warrants, in order to obtain some types of evidence and thus, protects the rights of ordinary systems. In more recent times, the use of technology has come to play a major role in the gathering of evidence and with this comes complications in the law. New technologies in relation to the criminal investigation process are mainly in reference to DNA evidence, genetic material that can place a suspect at the scene of a crime. The introduction of DNA evidence into the criminal investigation process has been extremely effective in achieving justice, as it is able to secure convictions. Initially, there were some setbacks to the use of DNA evidence
The indoor environment-first and foremost the indoor environment needs to be safe, and it needs to be all inclusive. This means that every child, no matter their age race, ethnicity, gender or abilities or special education needs, can all play. When considering the layout of the indoor area it needs to be spacious and it needs to accommodate children continuous change of interests and abilities so that children are able to grow and learn. If the indoor environment stayed the same each day, children would not be stimulated, they would get bored and they would not develop their learning. Furthermore, the environment needs to be of the highest quality, the toys need to be safe, and good enough to situmulate the childs brain. these toys need to
