Assessment of Economic Viability of Different Agroforestry Systems in Giri Catchment, Himachal Pradesh
Not AvailableIn Himachal Pradesh, 80 percent of its total population lives in villages. Their economy is depends on agriculture,
horticulture and animal husbandry. The practice of pure agriculture in HP is sufficient for the inhabitants to sustain only
their food requirements but, for other needs peoples are forced to exploit forests. The present investigation was carried
out in Giri catchment in located between 30O 33’ 48’’ and 31O 16’ 08’’ N latitude and 77O 02’ 32’’ to 77O 38’ 22’’ E longitude
in Himachal Pradesh. The net returns from agroforestry systems decreased, though statistically insignificant, in the
order agrisilviculture system (277415.00 Rs. ha-l yr-1) > agrisilvihorticulture system (270747.00 ` ha-l yr-1) >
agrihortisilviculture (269033.00 ` ha-l yr-1) > agrihortisilviculture (225880.30 ` ha-l yr-1) systems. The benefit-cost ratio in
silvipasture system was significantly higher (3.34) than all other systems and it decreased in the order: S6 (2.53) > S4 (2.38)
> S3 (2.17) > S1 (2.10) > S1 (1.87).Not Availabl
Medium modification of the shape of small-radius jets in central Pb-Pb collisions at root s(NN)=2:76 TeV
Abstract: We present the measurement of a new set of jet shape observables for track- based jets in central Pb-Pb collisions at √sNN = 2.76 TeV. The set of jet shapes includes the first radial moment or angularity, g; the momentum dispersion, pTD; and the differ- ence between the leading and sub-leading constituent track transverse momentum, LeSub.
These observables provide complementary information on the jet fragmentation and can constrain different aspects of the theoretical description of jet-medium interactions. The jet shapes were measured for a small resolution parameter R = 0.2 and were fully corrected to
particle level. The observed jet shape modifications indicate that in-medium fragmentation
is harder and more collimated than vacuum fragmentation as obtained by PYTHIA cal- culations, which were validated with the measurements of the jet shapes in proton-proton
collisions at √s = 7 TeV. The comparison of the measured distributions to templates for
quark and gluon-initiated jets indicates that in-medium fragmentation resembles that of quark jets in vacuum. We further argue that the observed modifications are not consistent with a totally coherent energy loss picture where the jet loses energy as a single colour charge, suggesting that the medium resolves the jet structure at the angular scales probed
by our measurements (R = 0.2). Furthermore, we observe that small-R jets can help to
isolate purely energy loss effects from other effects that contribute to the modifications of the jet shower in medium such as the correlated background or medium response
