Definition of Forensic Science

Forensics is a field of science dedicated to the methodical gathering and analysis of evidence to establish facts that can be presented in a legal proceeding. Though crime scenes and laboratories are perhaps, most often associated with forensics, there is also computer or network forensics, forensic accounting, forensic engineering and forensic psychiatry, among other specialized fields that are today an integral part of forensics. In the United States of America, forensics was a fairly obscure topic for the general public until the double-murder trial of Orenthal James Simpson in 1995. In the historic case that gripped the entire nation, weeks of testimony were heard on DNA blood evidence, shoeprint evidence, fiber evidence and other forensics. Since then, a bevy of forensics-based television shows have regularly topped the ratings, making it a household word.

Fingerprinting in Forensic Science

Fingerprints collected from a crime scene, or from items of evidence from a crime, can be used in forensic science to identify suspects, victims and other persons who touched the surface in question. Fingerprint identification emerged as an important system within various police agencies in the late 19th century. This system replaced anthropometric measurements as a more reliable method for identifying persons having a prior record, often under an alias name, in a criminal record repository. The science of fingerprint identification stands out among all other forensic sciences for many reasons because of its superiority and reliability.

Forensic Science Lesson Plans

A lesson plan is a teacher's detailed description of the course of instruction for an individual lesson. While there is no single way to construct one, most lesson plans contain some or all of the elements of the course. In today's modern teaching style, individual lesson plans are often inappropriate. Specific objectives and timelines may be included in the unit plan, but lesson plans are more fluid as they cater to the students needs and learning styles.

Solar System FAQs

The solar system form was formed about 4.5 billion years ago from a massive cloud. The massive cloud contained hydrogen, helium, and pinches of heavier elements such as oxygen, carbon, nitrogen, silicon, and iron. The materials in the massive cloud clumped together and the largest clump became a prostar. Compression of the prostar due to gravity caused the fusion of hydrogen into helium. This gave birth to the sun. In the inner hotter regions of the cloud, heavier elements of dust grains came together to form Mercury, Venus, Earth and Mars. In colder regions away from sun, frozen water, methane, and ammonia came together so quickly that their gravities attracted the nearby hydrogen and helium gases. These gases became the main ingredients in Jupiter, Saturn, Uranus, and Neptune.

The Centre Of Contemporary Cultural Studies

In the late 1970s the Centre of Contemporary Cultural Studies (CCCS), at Birmingham University, was involved in the publication of four major works.

Natural Gas Properties

Natural gas is a gaseous fossil fuel that has methane as its primary compound. It is derived from organic material that was deposited or buried under the earth, millions of years ago. It contains heavier gaseous hydrocarbons, like ethane propane, and butane as well as sulfur containing gases. Natural gas has certain properties that enable its use for industrial or domestic purpose. For instance, it contains non-poisonous ingredients that when inhaled gets absorbed into the blood.

Water Density

Water has incredible properties such as ice formation and gas formation depending on its temperature. However, water density is the most wonderful one.

Scientific Research Regarding Modern Material and Spiritual Sciences

Material Science can be defined as understanding the potentials of this material universe and then making apt use of them. On the other hand Spiritual Science deals with the advancement of our consciousness so as to attain eternal unlimited bliss (Ananda). Human beings need to pay heed to both these in a balanced manner. Based on spiritual tenets Vital Force consciousness is made balanced in an optimal fashion.

Types of Microscopes

Microscopes range from the simple single lens microscope to the sophisticated ones with imaging systems. Microscopes differ on the basis of their resolution, magnification, illumination method, type of image, field of view, degree of automation etc.

Surgical Microscopes

Surgical microscopes are one of the most exciting advancements in the surgical field. For more than half a century, surgeons around the entire world have been using surgical microscopes to perform intricate surgeries.

Biology: Insect Life-Cycles - The Mosquito - Culex pipiens

The mosquito (Culex pipiens) lays its eggs in stagnant water. The eggs stick together in a 'raft' and are buoyed up by the air trapped between them. The eggs hatch into larvae which escape into the water from the bottom of the egg cases.
