Abstract:
An attempt is made to study the possible relationship between the process of upwelling and zooplankton biomass in the shelf weters along the south west coast of India between Cape comorin and Ratnagiri based on oceanographic and Zooplankton
data collected by the erstwhile FAO/UNDP Pelagic Fishery Project,Cochin between 1973 and 1978. Different factors such as the depth from which the bottom waters are induced upwards during the process of upwelling,the depth to which the
bottom waters are drawn, vertical velocity of upwelling and the resultant zooplankton productivity were considered while arriving at the deductions.
Except for nutrients and phytoplankton productivity, for which simultaneous data is lacking, all the major factors were taken into consideration before cocluding- xon positive/negative correlation.

Abstract:
On line isotope separation techniques (ISOL) for production of ion beams of short-lived radionuclides
require fast separation of nuclear reaction products from irradiated target materials followed by a transfer into
an ion source. As a first step in this transport chain the release of nuclear reaction products from refractory
metals has been studied systematically and will be reviewed. High-energy protons (500 - 1000 MeV) produce
a large number of radionuclides in irradiated materials via the nuclear reactions spallation, fission and
fragmentation. Foils and powders of Re, W, Ta, Hf, Mo, Nb, Zr, Y, Ti and C were irradiated with protons
(600 - 1000 MeV) at the Dubna synchrocyclotron, the CERN synchrocyclotron and at the CERN PS-booster
to produce different nuclear reaction products.
The main topic of the paper is the determination of diffusion coefficients of the nuclear reaction products
in the target matrix, data evaluation and a systematic interpretation of the data. The influence of the ionic
radius of the diffusing species and the lattice type of the host material used as matrix or target on the
diffusion will be evaluated from these systematics. Special attention was directed to the release of group I, II
and III-elements. Arrhenius plots lead to activation energies of the diffusion process.
The purpose of this study was to evaluate the content growth of institutional repositories (IR) in
South India and analyse the type-wise growth of items available in these IRs and also discuss the
traits and trends exposed by them.
With the help of Registry of Open Access Repositories and Directory of Open Access
Repositories (OpenDOAR), 39 repositories were located in south India. From these, Personal
websites, the IRs that are currently not working and the repositories used for journal archiving
were excluded. A total of 22 operational IRs at 21 institutions were identified for the study.
Within a 15 month period, the data were collected from the 22 IRs twice for monitoring content
growth.
The content of nearly all IRs have grown over the 15 month period, and the overall content
growth rate was 7.82 per cent. Journal articles were the important content type of IRs, while
thesis and conference papers were the next common. Moreover, item monographs exhibited the
highest growth rate. Other categories, conference proceedings, and conference papers also
exhibited a high growth rate. The present study revealed that Indian repositories were actively
engaged in data curation activities, depositing a wide variety of items in their respective IRs.
Overall, South Indian repositories exhibited a slow growth rate and tended to become inactive.
Most South Indian Universities had not constituted the IRs, which led to the dominance of
English language material in these IRs.
The study was conducted only in South Indian IRs.
This is the first study in India, attempting to determine the type-wise growth of items in IRs.

The purpose of this study was to identify the digital curation practices in Institutional
Repositories (IRs) in South India.
A voluntary survey was conducted among the IR managers of 23 South Indian IRs, and the
response rate was 87%.
This study found that the active participation of South Indian IRs was only seen in a few digital
curation activities. However, Of the 33 digital curation activities analyzed, the active
participation of IRs was only seen in ten digital curation activities. The performance of
preservation activities was extremely low, and disagreements were recorded by the survey
participants towards several digital curation activities. The most disagreed digital curation
activities were emulation and cease data curation. All the participants had assigned metadata and
allowed file download in their IRs. Raman Research Institute had provided a good number of
digital curation services in their IR.
This is an in-depth study investigating the digital curation practice currently underway in South
Indian IRs, and the researcher could not find similar studies in this niche.
