During botanical studies conducted in Thiruvannamalai District of Tamil Nadu State, India as a part of compilation ofthe district flora, Tinospora sinensis (Lour.) Merr. was collected from Javvadhu ('Javadi') hills. It is a Red Listed medicinal plant which also forms an addition to the Flora of Tamil Nadu. It is presented here in detail with nomenclature, description, distribution data, threat status and medicinal information.

The invention of computer as well as information and communication technology has brought in many changes all over the world in all the fields. It has not left the medical field; there is a big revolution in the health care profession. Many new concepts have evolved in health care profession like telemedicine, electronic health record, health management information system, open access system, new publishing models etc. The clinicians and the scientists are not well informed about this development in India and the infrastructure is also not fully equipped in India. The librarians also find it very difficult to cope up with this situation. This paper deals with the challenges faced by the medical librarians. It also gives few resources that provide health science information.Keywords

Photovoltaic (solar) cells are gaining more popularity as an important source of energy. Photovoltaic power generation employs solar panels comprising a number of cells containing a photovoltaic material. The photovoltaic effect is the creation of a voltage in a material upon exposure to light. A wide variety of cell materials and designs are now in production, including thin film devices whose performance is monitored by Spectroscopic Ellipsometry (SE). The experimental next-generation cells such as organic thin films, promise low production cost and ease of manufacturing. Regardless of the material used, most solar cell designs rely on thin films, and the natural choice for studying and monitoring the performance of these films is Spectroscopic Ellipsometry. This paper reviews the current and emerging applications of SE to different solar cell films, structures and devices, production of energy from solar cells.Keywords

The present study was envisaged mainly to ascertain the influence of aquaculture on salinization of coastal groundwater resources in the Cuddalore district of Tamil Nadu located between 11°30'N–11°20'N and 79°38'E–79°48'E. Watershed-based multidisciplinary approach combining GIS and Remote Sensing, and hydro-geochemistry has been applied. The land-use study revealed that though aquaculture was initiated after 1991, the groundwater quality in some locations showed elevated total dissolved solids and electrical conductivity content during that time itself, supporting the fact that aquaculture has been initiated in in situ saline area. Land-use change dynamics showed no defined relationship between area of culture and the groundwater quality, indicating that there was no salinity build-up due to shrimp farming. Besides major chemical compositions, the hydro-geochemical analysis using Chadha’s plot suggests that reverse ion exchange is dominant in the study area due to the natural geological condition and it controls the groundwater quality rather than sea water incursion to a large extent. Thus these analyses clearly bring out the fact that shrimp farming is not the main reason for the source of salinity in the study area.Keywords
