Abstract

Preliminary study of the ultramafic suite of rocks emplaced concordantly in the Proterozoic supracrustals of the southern Rajasthan (Aravalli Supergroup) indicates their komatiitic nature. Though the diagnostic spinifex texture is not observed in the highly serpentinised and metamorphosed ultramafics, the amygdaloidal structure and the previously reported igneous joints provide textural evidences for the extrusion of the ultramafic lava. The altered ultramafics still retain certain chemical signatures (high MgO and Mg-No., low Ti0₂, Al₂O₃and alkalis) of standard komatiites.

Abstract

Agriculture is an important sector where majority of women labour force is engaged and because of using age old tools and implements most of their tasks are tedious monotonous and drudgery prone. Researchers of ICAR institutes effort in introducing various time and energy saving tools to relieve their drudgery in agricultural work has been proven effective in many times. Present study in OFT form is an effort to assess the impact of improved garden tools i.e. Garden rack, Circular blade weeder and hand fork on economic viability and physiological workload of women in comparison with traditional age old tools Kuhrpi and Hoe conducted in 5 districts of Assam comprising 40 beneficiaries and 40 non-beneficiaries. Result revealed that less time required in all selected activities by using improved garden tools resulted less labour cost than simple Hoe and Khurpi. Moreover, differences of energy expenditure (both by using improved garden tools and traditional Kuhrpi and Hoe) in same activities indicates it helps in reducing physiological fatigue. Opinion perceived by farm women of using such tools is highly acceptable than Hoe and Khurpi.

Abstract

Serendipity, in various shades of semantic legitimacy, is abundantly evident in history of drug discovery. In the present era, although new concept of rational drug design has been introduced even then, lots of drugs have arisen, and continue to arise, from chance observation and correct scientific methods. Chance does not produce drugs; but where chances have played a pivotal role in drug discovery, the event may be considered as serendipitous.

Keywords

Discovery, Serendipity, Penicillin.
