As a consequence, in the past fifty years, there has been a paradigm shift in our interpreting the life process. In the process, modern biology had acquired a truly interdisciplinary character in which all streams of sciences have made monumental contributions. Because of such rapid emergence as a premier subject of teaching and research; a necessity to restructure classical teachings in biology was recognised by the academics worldwide. In tune with such trends, the academic leadership of Jawaharlal Nehru University conceptualised the School of Life Sciences as an interdisciplinary research/teaching programme unifying various facets of biology while reflecting essential commonality regarding structure, function and evolution of biomolecules. The School was established in 1973 and since offering integrated teaching and research at M. Sc/ Ph.D level in various sub-disciplines in life sciences. Since inception, it remained dedicated to its core objectives and evolved to be one of the top such institutions in India and perhaps in South East Asia.

Through this exhibition, we supported the Year of Water initiative as observed by the Government of Karnataka. It also featured H2O Today, a popular traveling exhibition by the Smithsonian Institution. We encouraged visitors to explore the collective experiences of water and refIect on future challenges through a range of dynamic exhibits and workshops. We presented 15 exhibits spread across three floors of Bangalore International Centre, which examined the role of water in our lives, beyond the value that we derive from it. These exhibits were brought to life through 45 connected programmes such as workshops, lectures, master classes, film screenings and musical performances. Participants engaged with the latest research and thinking on water, and examined its cultural significance, by interacting with scholars and artists from around the world. We also provoked them to begin a dialogue on water as an urgent concern for the city of Bengaluru, and global challenge of the Anthropocene. Ice Painting by Dorota Borowa.

  • Vol: Ii (1938) of “Flora of Assam”
    Plant Archives Vol. 14 No. 1, 2014 pp. 87-96 ISSN 0972-5210 AN UPDATED ACCOUNT OF THE NAME CHANGES OF THE DICOTYLEDONOUS PLANT SPECIES INCLUDED IN THE VOL: I (1934- 36) & VOL: II (1938) OF “FLORA OF ASSAM” Rajib Lochan Borah Department of Botany, D.H.S.K. College, Dibrugarh - 786 001 (Assam), India. E-mail: [email protected] Abstract Changes in botanical names of flowering plants are an issue which comes up from time to time. While there are valid scientific reasons for such changes, it also creates some difficulties to the floristic workers in the preparation of a new flora. Further, all the important monumental floras of the world have most of the plants included in their old names, which are now regarded as synonyms. In north east India, “Flora of Assam” is an important flora as it includes result of pioneering floristic work on Angiosperms & Gymnosperms in the region. But, in the study of this flora, the same problems of name changes appear before the new researchers. Therefore, an attempt is made here to prepare an updated account of the new names against their old counterpts of the plants included in the first two volumes of the flora, on the basis of recent standard taxonomic literatures. In this, the unresolved & controversial names are not touched & only the confirmed ones are taken into account. In the process new names of 470 (four hundred & seventy) dicotyledonous plant species included in the concerned flora are found out. Key words : Name changes, Flora of Assam, Dicotyledonus plants, floristic works.

The experiments were performed under constant light (ca. 500 lux) and temperature (about 20 °C) conditions. The period of the leaflet was then around 5 min. Leaflets moving up and down in a magnetic field of approximately 50 mT flux density increased the period by about 10% due to a slower motion in the “up” position. Since during this position a rapid change of the extracellular potentials of the pulvinus occurs, it is proposed that the effects are mediated via the electric processes in the pulvinus tissue.
