The markers and colored buoys serve as the "traffic signals" that direct boats to safety. Lateral navigation markers and non-lateral markers of the US Aid to navigation System must be learned for all operators. A green-lighted buoy marks the border/edge of the channel on the operators' port (left side) as the boat enters from open sea. The odd number 3 signals your direction and distance in returning from open sea( as the number increases).
The two major contribution in forensic science made by Hans Gross are the following:
1. He is one of the founders of criminalistics for his research on the subject and the release of his book criminal investigation in 1891. The book was the first of its kind to be published which helps establish the science of forensics especially in terms of a cross transfer evidence from criminal to the victim.
2. He detailed the assistance that investigators could expect from the fields of microscopy, chemistry, physics, mineralogy, zoology, botany, anthropometry and fingerprinting. He later introduces the forensic journal, which improves methods of scientific crime investigation.
