Record catch of rock perch, Epinephelus fasciatus by bottom trawling off Ratnagiri
A productive fishing ground for rock perch (Epinephelus fasciatus) was located off Ratnagiri between 17 degree 00' to 17 degree 10' N latitude and 72 degree 20' to 72 degree 30' E longitude, around a depth of 96m during November, 1983. An average catch of 2 ton/hr. was recorded. Length frequency studies of E. fasciatus indicate the probability of a nursery ground consisting of three brood stocks. Hydrographic studies of the ground revealed that the bottom water was oxygen deficient below a strong thermocline extending from 15-75 m depth with the recorded bottom temperature amounting to 20.5 degree C
Calibrations of hydro-acoustic instruments onboard FORV Sagar Sampada
Calibration is carried out to keep up the precision of the instruments by
determining their calibre. CaUbration of hydro acoustic equipments onboard FORV
Sagar Sampada was carried out periodically and the performance records were
maintained. Deviation and the deficiencies were noted down for applying the correction
while interpreting the output of the instruments
Proceedings of the Second workshop on scientific results of FORV Sagar Sampada
Since inception in 1984, the Fisheries and Oceanographic Research Vessel
Sagar Sampada, with sophisticated modern facilities onboard, has undertaken more
than 140 cruises all over the Indian Ocean primarily in our Exclusive Economic Zone
for fishery and oceanographic survey. Scientists from many institutions have made
use of this facility to explore the resource potential in our sea and to understand its
correlation with the environmental parameters. These survey and exploration efforts
are continuing.
This volume contains many papers which are the outcome of research work carried
out onboard 'Sagar Sampada' during last five years (1989-1993) and presented in a
Workshop to evaluate the scientific work. About 60 papers, included in this volume,
bring out the results pertaining to environmental assessment, hydrology, productivity
estimates, fishery resources availability, fishing technology, pollution monitoring etc.
These relate mainly to the Arabian Sea, Bay of Bengal and Lakshadweep, Andaman
and Nicobar Islands groups in the EEZ of India. These efforts along with other
mission-oriented cruises have yielded valuable information on the fishery resources
and their distribution in space and time
Carbon Nanotubes Generated from Polyphenyl Acetylene
The carbonization of polyphenyl acetylene in alumina matrix yields uniform, cylindrical, monodisperse carbon nanotubes with outer diameter almost equal to pore diameter of the alumina membrane used. The electrochemical characteristics reveal that the charge transfer at the composite electrode based on carbon
nanotube might be higher compared to that of planar graphite, glassy carbon and composite electrode based
on commercially available Vulcan XC72R carbon. Pt-Ru nanoparticles are highly dispersed inside the tube
with an average particle size of 1.7 nm as revealed by HR-TEM images
Manual / Issue 3 / Circus
Manual, a journal about art and its making. Circus. The third issue centers on the theme of Circus. Includes analyses of various pieces in the museum\u27s archive, a fold-out poster by Jim Drain, and a selection of artworks owned by the museum that loosely address said theme.
Softcover, 62 pages. Published 2014 by the RISD Museum. Manual 3 (Circus) contributors include Gina Borromeo, Alison W. Chang, Michelle Clayton, Jim Drain, Daniel Heyman, Andrew Martinez, Ellen McBreen, Thangam Ravindranathan, Rebecca Schneider, Susan Smulyan, and Gwen Strahle.https://digitalcommons.risd.edu/risdmuseum_journals/1002/thumbnail.jp
Why are MD simulated protein folding times wrong?
The question of significant deviations of protein folding times simulated using molecular dynamics from experimental values is investigated. It is shown that in the framework of Markov State Model (MSM) describing the conformational dynamics of peptides and proteins, the folding time is very sensitive to the simulation model parameters, such as forcefield and temperature. Using two peptides as examples, we show that the deviations in the folding times can reach an order of magnitude for modest variations of the molecular model. We, therefore, conclude that the folding rate values obtained in molecular dynamics simulations have to be treated with care
A patient-derived explant (PDE) model of hormone-dependent cancer
Breast and prostate cancer research to date has largely been predicated on the use of cell lines in vitro or in vivo. These limitations have led to the development of more clinically relevant models, such as organoids or murine xenografts that utilize patient-derived material; however, issues related to low take rate, long duration of establishment, and the associated costs constrain use of these models. This study demonstrates that ex vivo culture of freshly resected breast and prostate tumor specimens obtained from surgery, termed patient-derived explants (PDEs), provides a high-throughput and cost-effective model that retains the native tissue architecture, microenvironment, cell viability, and key oncogenic drivers. The PDE model provides a unique approach for direct evaluation of drug responses on an individual patient's tumor, which is amenable to analysis using contemporary genomic technologies. The ability to rapidly evaluate drug efficacy in patient-derived material has high potential to facilitate implementation of personalized medicine approaches.Margaret M. Centenera, Theresa E.
