CELEBRITY OF THE MONTH
Sir Jagadish Chandra Bose
159th Birthday (30 November 1858 – 23 November 1937)
One of the Fathers of Radio Science

Jagdish Chandra was born on November 30, 1858. He was born in a Hindu Kayastha Bengali family. He was a polymath; a physicist, botanist, biologist, archaeologist and also a reputed writer of science fiction. He championed the investigation of radio and microwave optics, made an important contribution to plant science. He was the person who put India in the world map by his scientific flair and ingenuity. He is one of the most prominent first Indian scientists who proved by experimentation that both animals and plants share much in common. He demonstrated that plants are also sensitive to heat, cold, light, noise and various other external stimuli. His experiments on the quasi-optical properties of very short radio waves (1895) led him to make improvements on the coherer, an early form of radio detector, which have contributed to the development of solidstate physics. IEEE named him one of the fathers of radio science. On 29 March 1904 he became the first Indian to get a US patent, for his "detector for electrical disturbances".

PERSPECTIVE

An overview of white rust disease in Brassica: taxonomical, biochemical aspects and management approaches

Muhammad Asif, Muhammad SaqibMushtaq, Hina Firdous, Muhammad Mubashar Zafar, Ali Imran, Tanvir Ahmad, Hafiz Muhammad Arslan Abid, Hafiz Saad Bin Mustafa

Rapeseed (Brassica napus L.) belongs Brassicaceae family is the second most important oilseed crop in Pakistan after cotton. It contains 40-46% oil content and 22% protein. There are several factors which lowers seed yield like abiotic and biotic stresses. Alternaria blight and white rust diseases are the major threat for reducing Brassica seed yield in Pakistan

ANALYSIS

Assessment of physico-chemical parameters in the estuarine water of Devgad mangrove swamps, Maharashtra coasts

Nisha R Mugade, Jagdish B Sapkale

The present research work has attempted to analyse the physico-chemical parameters of estuarine water of Devgad mangrove swamps of coastal Maharashtra. Water samples were collected from mouth zone, middle zone and upstream zone of Devgad estuary for pre and post monsoon season.

RESEARCH

Estimation of chloride absorption in concrete cubes with finite moisture content

Balakrishna MN, Fouad Mohamad, Robert Evans, Rahman MM

The exposure of concrete infrastructures to chloride ions is the primary cause of premature corrosion of steel reinforcement. The intrusion of chloride ions, present in de-icing salts into reinforced concrete can cause steel corrosion if oxygen and moisture are also available to sustain the reaction

ANALYSIS

B. Feng’s theory - the prediction of mass spectrum of elementary particles and the confidence of at least 4-D space-time (Part I)

Zhen-hua Mei

Based on Einstein’s four-dimensional space time in general relativity and the symmetry principle, B. Feng created his theory in field of elementary particle physics. He proposed 16-regular polytope to express the symmetries of elementary particles’ manifold in 4-D space.
