CELEBRITY OF THE MONTH
Chandrasekhara Venkata Raman
128th Birthday, (7 November 1888 – 21 November 1970)
Raman Effect; Raman Scattering

Chandrasekhara Venkata Raman was born at Trichinopoly in Southern India on November 7th, 1888. He was an Indian physicist whose work was influential in the growth of science in the world. He was the recipient of the Nobel Prize for Physics in 1930 for the discovery that when light traverses a transparent material, some of the light that is deflected changes in wavelength. This phenomenon is now called Raman scattering and is the result of the Raman Effect. He was the first Asian and first non-White to receive any Nobel Prize in the sciences. Before him Rabindranath Tagore had received the Nobel Prize for Literature in 1913. He became Professor at the Indian Institute of Science at Bangalore (1933-1948). Raman retired from the Indian Institute of Science in 1948 and established the Raman Research Institute in Bangalore, Karnataka a year later. He also founded the Indian Journal of Physics in 1926, of which he is the Editor. Raman sponsored the establishment of the Indian Academy of Sciences and has served as President since its inception.

SURVEY

A Survey of Traditional Medicinal Knowledge for the Treatment of Asthma, Cold, Cough, Fever, Jaundice and Rheumatism of Santal Tribal Practitioners of Chapai Nawabganj District, Bangladesh

Moriom Jamila, Mahbubur Rahman AHM

A Survey of traditional medicinal knowledge for the treatment of asthma, cold, cough, fever, jaundice and rheumatism of Santal tribal practitioners of Chapai Nawabganj district, Bangladesh was carried out. The information presented in this paper was gathered by field visit, participatory observation, group discussion and interviews with questionnaires in the year July 2013 to June 2015 after frequent field visit in the study area.

ANALYSIS

Guards of Vehicles need to Guard their Health

Vara Saritha, Manoj Kumar Karnena

It has become inevitable for the consumers to look beyond the traditional retail stores towards organized outlets with changing retail scenario, which led to packed consumers with overcrowded parking in the cellars of many malls. The overwhelming flow of vehicles release great concentrations of pollutants like oxides of carbon monoxide, nitrogen, respirable particles, sulfur dioxide, hydrocarbons and lead and into the areas whose dispersion is lesser resulting in health effects.

Common natural waves in dissipative inhomogeneous plane bodies

Safarov Ismail Ibrahimovich, Teshayev Mukhsin Khudoyberdiyevich, Akhmedov Maqsud Sharipovich, Boltaev Zafar Ihterovich

In this paper the distribution of natural waves in dissipative neodnorodnonyh flat bodies. Wave motion is described by linear integral-differential equations. Solving this problem, we obtain the relationship between the velocity of the wave and its length. The problem of this kind is of great interest to geophysicists in the field of engineering and construction.

THESIS

Synthesis, characterization and biological activities of Tricyclohexyltin (IV) complexes with various oxygen donor Ligands

Lala Rukh

Tricyclohexyltin(IV) complexes have been synthesized by reacting various oxygen donor ligands with Cy3SnCl in 1:1/1:2 M/L ratio in anhydrous methanol under reflux conditions. The ligands and synthesized organotin(IV) complexes have been characterized by elemental analysis, FT-IR, 1H NMR spectroscopy and semi-empirical analysis.

Synthesis, spectroscopy and biological activities of homobimetallic complexes with the ligand having O- and S-donor sites

Mudassir Jabeen

Homobimetallic complexes of organotin(IV) with oxygen and sulphur donor ligand have been synthesized at room temperature under stirring conditions by using R2SnCl2 (R = Me, n-Bu) and R3SnCl (R = Me, n-Bu, Ph) in 1:1 molar ratio. The synthesized complexes have been characterized by elemental analysis, IR and multinuclear NMR (1H, 13C) spectroscopy.
