Unusual landing of Sardinella longiceps at Pamban in Ramanathapuram district, Tamil Nadu
On 09-05-2007, 1000 kg of Sardinella longiceps was
landed in a single unit of Choodai Valai (Sardine
gillnet), operated near Thangachimadam, in Palk Bay,
at a depth of 10 meters. The net was operated from a
Vallam fitted with an inboard engine, at a distance of 5
km. from the shore, with the help of 3 persons
Fishing methods in coral reef areas of the Gulf of Mannar
Fishing methods being practised in the reef areas
of the Gulf of Mannar for finfishes are trawling,
gillnetting, fishing by hooks and lines and traps. Out of
these, the most important device is trawling by which
the most diverse and the highest quantity of finfishes
are being landed from coral reef areas in this region
Studies of transverse and longitudinal relaxations of Mn in molecular cluster magnet MnAc
The transverse and longitudinal relaxation rates 1/ and 1/ of
Mn in molecular cluster magnet MnAc have been measured al low
temperatures down to 200mK and in the fields upto 9T. Both of 1/ and
1/ exhibit remarkable decreases with decreasing temperature and with
increasing field, with the relative relation . In the
analysis, we adopt a simple model that the thermal fluctuation of the cluster
spin =10 associated with the spin-phonon interactionis, is only due to the
excitation to the first excited state from the ground state with the average
life-times and (). We show that
1/ is interpreted in terms of the strong collision regime as given by
1/, and that 1/ is understood by the high-frequency limit based
on standard perturbation treatment for the step-wise fluctuating field, thus
being proportional to 1/.Comment: 12 pages, 11 fugures, revtex
Results of the mother oyster culture and pearl production in Pinctada fucata (Gould) in the inshore waters of the Gulf of Mannar and Palk Bay
It is established experimentally that the inshore areas of the Gulf of
Mannar and Palk Bay bordering Mandapam Camp can profitably be
used for mother oyster culture and cultured pearl production.
The depth of the inshore waters of the Gulf of Mannar is
comparatively deeper where the raft culture can be adopted from
November to May. whereas, the nearshore waters of Palk Bay is shallow where rack can be used to farm the oysters from June to October, thus a continued farming is
possible in all months in a calender year.
Though the hydrological and environmental conditions of both the
seas are almost same, it is found that Gulf of Mannar is better suited
for mother oyster culture as indicated by the better growth rates
of spat and oysters. If farming is done properly,
high survival rates of spat, mother oysters and implanted oysters can
be achieved with an enhanced rate of production of better quality
cultured pearls
Hatchery seed production and nursery rearing of Indian pearl oyster Pinctadafucata (Gould) under onshore and offshore conditions at Mandapam, Tamil Nadu
A full fledged pearl oyster hatchery was established at R.C. of
CMFRI, Mandapam Camp along with a temperature controlled micro algal
culture laboratory. The hatchery house four 5 ton capacity circular FRP
tanks for storage of filtered sea water and 28 nos of 1.5 ton rectangular FRP
tanks for larval rearing. A central drain of 80 m length connects the
hatchery to the sea. Sea water supply is effected through 7.5 and
10 HP pumps connected to sedimentation tanks, ground level
sumps and to overhead tank. Two sand filters were erected for
effective filtering of sea water. Aeration is provided with air blowers
and air compressors. The annual production capacity is estimated to be
2.8 million spats. Induced spawning and larval rearing gave encouraging
results and 0.7 million spats were produced during June-August 1997
Walk to me when I smile, step back when I’m angry: emotional faces modulate whole-body approach–avoidance behaviors
Facial expressions are potent social cues that can induce behavioral dispositions, such as approach–avoidance tendencies. We studied these tendencies by asking participants to make whole-body forward (approach) or backward (avoidance) steps on a force plate in response to the valence of social cues (happy or angry faces) under affect-congruent and incongruent mappings. Posturographic parameters of the steps related to automatic stimulus evaluation, step initiation (reaction time), and step execution were determined and analyzed as a function of stimulus valence and stimulus–response mapping. The main result was that participants needed more time to initiate a forward step towards an angry face than towards a smiling face (which is evidence of a congruency effect), but with backward steps, this difference failed to reach significance. We also found a reduction in spontaneous body sway prior to the step with the incongruent mapping. The results provide a crucial empirical link between theories of socially induced action tendencies and theories of postural control and suggest a motoric basis for socially guided motivated behavior
Negative Regulation of Interferon-β Gene Expression during Acute and Persistent Virus Infections
The production of type I interferons (IFNs) in response to viral infections is critical for antiviral immunity. However, IFN production is transient, and continued expression can lead to inflammatory or autoimmune diseases. Thus, understanding the mechanisms underlying the negative regulation of IFN expression could lead to the development of novel therapeutic approaches to the treatment of these diseases. We report that the transcription factor IRF3 plays a central role in the negative regulation of interferon-β (IFNβ) expression during both acute and persistent (chronic) virus infections. We show that the degradation of IRF3 during acute infections, rather than the activation of transcriptional repressors, leads to the down regulation of IFNβ expression. We also show that the block to IFNβ expression in mouse embryonic fibroblasts that are persistently infected with Sendai virus (SeV) correlates with the absence of transcriptionally active IRF3. Remarkably, ongoing protein synthesis and viral replication are required to maintain repression of the IFNβ gene in persistently infected cells, as the gene can be activated by the protein synthesis inhibitor cycloheximide, or by the antiviral drug ribavirin. Finally, we show that the SeV V protein inhibits IRF3 activity in persistently infected cells. Thus, in conjunction with the known interference with STAT1 by the SeV C protein, both IFN activation and its signaling pathways are blocked in persistently infected cells. We conclude that the transcription factor IRF3 is targeted for turnover and inactivation through distinct mechanisms from both the host cells and virus, leading to the inhibition of IFNβ gene expression during acute and persistent viral infections. These observations show that IRF3 plays a critical role, not only in the activation of the IFNβ gene, but also in the controlling the duration of its expression. (284 words
