In the year 1679, Antonie Van Leeuwenhock made a groundbreaking discovery - the presence of spermatozoa in semen. This revelation marked a significant milestone in the understanding of human biology.
Fast forward to 1492, Christopher Columbus, a European explorer, embarked on his first voyage to the Americas, where he discovered the island of Hispaniola. Upon landing, he encountered the indigenous Taíno people, marking the beginning of a new era in human history.
Moving on to a different field, we delve into the world of physics. In explosions, damage is primarily caused by shock waves, intense flame, and the force of projectiles or missiles.
E.R. Henry penned down 'Classification and Uses of Fingerprints', a book that has played a crucial role in the field of criminalistics, which can be defined as the application of Forensic Science to criminal investigations.
In the realm of biology, Heme, a molecule found in Red Blood Cells (RBCs), plays a vital role in carrying Oxygen (O) and Carbon Dioxide (CO) to and from cells.
Hyrtl's law states that the body of the sternum in male is more than twice the length of the manubrium.
In the field of chemistry, the internal standard used for the determination of alcohol by head space gas chromatography is N-propanol. In prompt Neutron Activation Analysis (NAA), gamma rays are detected.
The cephalic index, a measure used in anthropology, is calculated by the formula Maximum breadth of the skull/Maximum length of the skull×100.
In the world of forensic science, the first technique that was adopted for DNA analysis was RFLP (Restriction Fragment Length Polymorphism). An AK-47 rifle can fire both semi and fully automatic.
The order of increasing frequency of occurrence of fingerprint patterns is Arch, Whorl, Loop. Restriction enzymes, essential tools in molecular biology, cut DNA at specific sites.
At a scene of explosion, damage to nearby trees such as broken branches and shed leaves is often due to shock waves. In criminalistics, conduct money is given to offset expenses incurred by a witness.
In the compound microscope, an object placed just beyond the lower focal point of the objective lens forms an enlarged real image within the lower focal plane of the ocular.
In the microcrystal tests for drug analyses, some tests can be confirmatory in the hands of an experienced microscopist. The law that governs gas-liquid chromatography is Henry's Law.
In Walker's test, acetic acid vapors convert nitrites into nitrous acid. McNaughten's rule, included in S. 84 IPC, refers to the criminal responsibility of the mentally ill.
Beer's law is a limiting law as it describes absorption behaviour only of dilute solutions. Rape cases should preferably be tried by a woman judicial officer according to S.26 (a) CrPC.
In some instances, the consistency of paint is adjusted by solvent. In forensic science, the first technique adopted for DNA analysis was RFLP (Restriction Fragment Length Polymorphism).
