Goat fish resources of India with special reference to its occurrence in the shrimp trawlers at Sakthikulangara and Cochin Fisheries Harbour
The goatfishes or red mullets of the family Mullidae form one of the important ground fish resources along the Indian coasts. A comparative study in the catch indices points out that an annual average of 3,700 t were landed along the east coast during the period 1978â'87 accounting to more than 70% of the total goat fish landings from the seas around India. The percentage composition analysis at Cochin Fisheries. Harbour indicated highly fluctuating trend in the monthly catches were recorded and tabulated. Upeneus vittatus was the predominant species recorded in both centers during the period of observation

Precision Measurement of the Mass Difference
We have measured the vector-pseudoscalar mass splitting , significantly more precise than the previous
world average. We minimize the systematic errors by also measuring the
vector-pseudoscalar mass difference using the radiative
decay , obtaining
. This is
then combined with our previous high-precision measurement of
, which used the decay . We also
measure the mass difference MeV, using the
decay modes of the and mesons.Comment: 18 pages uuencoded compressed postscript (process with uudecode then

Observation of a New Charmed Strange Meson
Using the CLEO-II detector, we have obtained evidence for a new meson
decaying to . Its mass is
{}~MeV/ and its width is ~MeV/. Although we do not
establish its spin and parity, the new meson is consistent with predictions for
an , , charmed strange state.Comment: 9 pages uuencoded compressed postscript (process with uudecode then

Surface chemical and color characterization of juvenile tectona grandis wood subjected to steam-drying treatments
ArtĂculoThe color of Tectona grandis wood is an attribute that favors its commercialization, however, wood
color from fast-growth plantation trees is clear and lacks uniformity. The aim of this work is to
characterize steamed teak wood by means of the Fourier transform infrared spectroscopy (FTIR)
and L a b color systems. Two moisture conditions (green and 50%) and two grain patterns (°at
and quarter) of boards were analyzed through the application of diÂźerent steaming times (0, 3, 6, 9,
12, 15 and 18 h). The FTIR results showed that the bands at 1158, 1231, 1373 and 1419 cm 1 did not
show any change with steaming, whereas the bands at 1053, 1108, 1453, 1506, 1536, 1558, 1595,
1652, 1683, 1700 and 1733 cm 1 presented a decrease in the intensity with the steaming time. The
band at 1318 cm 1 was the only one that increased. Lightness (L ) was the most aÂźected parameter,
followed by yellowness (b ), while redness (a ) showed the smallest change. Surface color change
( E ) presented the lowest value between 3 h and 6 h of steam-drying in the boards with °at grain,
whereas for boards with quarter grain, the smallest E value was obtained after 18 h of steaming
Search for CP Violation in the Decay Z -> b (b bar) g
About three million hadronic decays of the Z collected by ALEPH in the years
1991-1994 are used to search for anomalous CP violation beyond the Standard
Model in the decay Z -> b \bar{b} g. The study is performed by analyzing
angular correlations between the two quarks and the gluon in three-jet events
and by measuring the differential two-jet rate. No signal of CP violation is
found. For the combinations of anomalous CP violating couplings, and , limits of \hat{h}_b < 0.59h^{\ast}_{b} < 3.02$ are given at 95\% CL.Comment: 8 pages, 1 postscript figure, uses here.sty, epsfig.st
Production and Decay of D_1(2420)^0 and D_2^*(2460)^0
We have investigated and final states and
observed the two established charmed mesons, the with mass
MeV/c and width MeV/c and
the with mass MeV/c and width
MeV/c. Properties of these final states, including
their decay angular distributions and spin-parity assignments, have been
studied. We identify these two mesons as the doublet predicted
by HQET. We also obtain constraints on {\footnotesize } as a function of the cosine of the relative phase of the two
amplitudes in the decay.Comment: 15 pages in REVTEX format. hardcopies with figures can be obtained by

Search for supersymmetry with a dominant R-parity violating LQDbar couplings in e+e- collisions at centre-of-mass energies of 130GeV to 172 GeV
A search for pair-production of supersymmetric particles under the assumption
that R-parity is violated via a dominant LQDbar coupling has been performed
using the data collected by ALEPH at centre-of-mass energies of 130-172 GeV.
The observed candidate events in the data are in agreement with the Standard
Model expectation. This result is translated into lower limits on the masses of
charginos, neutralinos, sleptons, sneutrinos and squarks. For instance, for
m_0=500 GeV/c^2 and tan(beta)=sqrt(2) charginos with masses smaller than 81
GeV/c^2 and neutralinos with masses smaller than 29 GeV/c^2 are excluded at the
95% confidence level for any generation structure of the LQDbar coupling.Comment: 32 pages, 30 figure
