Question

Match the technique given in column I with its relation to column II correctly.

Answer 1

A Ultrasound - 4 (s) Lead zirconate

B Endoscopy - 3 (r) Tubular abnormalities

C Hallucinogen - 2 (q) Bhang and charas

D Bloch and Purcell - 1 (p) NMR

Ultrasound is a type of imaging. It uses high-frequency sound waves to look at organs and structures inside the body. Health care professionals use it to view the heart, blood vessels, kidneys, liver, and other organs. During pregnancy, doctors use ultrasound to view the fetus.

Lead zirconate titanate is an intermetallic inorganic compound that shows a marked piezoelectric effect, meaning that the compound changes shape when an electric field is applied. It is used in a number of practical applications such as ultrasonic transducers.

Endoscopy is a nonsurgical procedure used to examine a person's digestive tract. Using an endoscope, a flexible tube with a light and camera attached to it, your doctor can view pictures of your digestive tract on a color TV monitor. It helps in diagonosing tubular abnormalities.

A hallucinogen is a psychoactive agent which can cause hallucinations, perceptual anomalies,etc.

Hallucinogens are a class of drugs that cause hallucinations—profound distortions in a person’s perceptions of reality.

Bhang -These are large green leaves and flowering shoots of either the male or the female plants. In most of the recipes, only the leaves are used. Bhang is not used for smoking. It is used to make beverages such as Thandai, Lassi, and Halwa. Bhang can also be used in making Vegetable Pakora. The problem is that oil used for frying becomes laced with the narcotic chemical.

Charas is the resin extracted from the top leaves and unfertilized flower of young female plant. The leaves and flowers are rubbed in the hands. The resin stuck to the hand is collected.

The Nobel Prize in Physics 1952 was awarded jointly to Felix Bloch and Edward Mills Purcell "for their development of new methods for nuclear magnetic resonance imaging.

Edward M. Purcell first observed nuclear magnetic resonance (NMR) in 1945 at the MIT Radiation Laboratory.

Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy, is a research technique that exploits the magnetic properties of certain atomic nuclei. This type of spectroscopy determines the physical and chemical properties of atoms or the molecules in which they are contained.
