The increasing volume of time-based generated data and the shift in storage technologies suggest that we might need to reconsider indexing. Several workloads like social and service monitoring often include attributes with implicit clustering because of their time-dependent nature. In addition, solid state disks (SSD) (using flash or other low-level technologies) emerge as viable competitors of...
“broussonetia papyrifera” (chinese mulberry) pollen is an important source of allergens in regions surrounding shanghai, china. to identify and purify major allergens from “b. papyrifera” pollen that reacted with serum antibodies from sensitized patients, “b. papyrifera” pollen was defatted, dried, and extracted proteins were separated using sp cationic exchange or q anionic exchange columns. s...
the aim of the present study was to find the best or optimum topology of six chicken populations, which were genotyped based on nine highly polymorphic microsatellite markers. to reach this goal, different genetic distances based on infinite allele model (iam), stepwise mutation model (smm) and drawing phylogentic trees on un-weighted pair-group method using arithmetic averages (upgma) method w...

for a graph $g$ with edge set $e(g)$, the multiplicative second zagreb index of $g$ is defined as $pi_2(g)=pi_{uvin e(g)}[d_g(u)d_g(v)]$, where $d_g(v)$ is the degree of vertex $v$ in $g$. in this paper, we identify the eighth class of trees, with the first through eighth smallest multiplicative second zagreb indeces among all trees of order $ngeq 14$.
we give sharp upper bounds on the zagreb indices and lower bounds on the zagreb coindices of chemical trees and characterize the case of equality for each of these topological invariants.
plantlet regeneration through indirect organogenesis of flame gold tree (koelreuteria elegans laxm.)
koelreuteria elegans, popularly known as “flame gold” is an ornamental tree. in vitro callus induction and regeneration from various explants (eaf segments and cotyledonary leaf) were studied on modified ms medium. the highest callus induction rate (80%) and multiplication was obtained in 2 mg/l 2,4-d from leaf segments. calli transferred in 1.5 mg/l bap resulted in efficient shoot regeneration...
