Raja Rao’s novel Kanthapura (1938) is the first major Indian novel in English. It is a fictional but realistic account of how the great majority of people in India lived their lives under British rule and how they responded to the ideas and ideals of Indian nationalism. The book has been considered by many to be the first classic modern Indian writing in English and is thought of as one of the best, if not the best, Gandhian novels in English.

Magnetic Resonance Imaging (MRI) is a medical imaging technique used in radiology to visualize internal structures of the body in detail. MRI makes use of the property of nuclear magnetic resonance (NMR) to image nuclei of atoms inside the body. An MRI scanner is a device in which the patient lies within a large, powerful magnet where the magnetic field is used to align the magnetization of some atomic nuclei in the body, and radio frequency fields to systematically alter the alignment of this magnetization. This causes the nuclei to produce a rotating magnetic field detectable by the scanner— and this information is recorded to construct an image of the scanned area of the body.

Fully mature or ripe grapes contain about an equal concentration of glucose and fructose, which are the simple sugars yeast ferment to form alcohol and carbon dioxide. Ripe grapes contain ~ 20% of glucose. During ripening the sucrose molecules are hydrolyzed (inverted) by the enzyme invertase into glucose and fructose. By the time of harvest, between 15-25% of the grape will be composed of simple sugars. Both glucose and fructose are six-carbon sugars but three, four, five and seven-carbon sugars are also present in the grape. At time of harvest, there is usually an equal amount of glucose and fructose molecules in the grape; however, as the grape over ripens the level of fructose will become higher.

Throughout most of the history of Western science, all scientific literature was written in Latin. Only recently has it been written in spoken languages like English. The use of Latin names has remained so that scientists that speak different languages can understand what they are talking about. Another reason is that many plants and animals have common names that differ by region. Having a Latin name avoids confusion among scientists.

Murmurs are pathologic heart sounds that are produced as a result of turbulent blood flow that is sufficient to produce audible noise. A functional murmur or “physiologic murmur” is a heart murmur that is primarily due to physiologic conditions outside the heart, as opposed to structural defects in the heart itself. Murmurs may also be the result of various problems, such as narrowing or leaking of valves, or the presence of abnormal passages through which blood flows in or near the heart. Such murmurs are known as pathologic murmurs.
