Track clustering with a quantum annealer for primary vertex reconstruction at hadron colliders
Clustering of charged particle tracks along the beam axis is the first step
in reconstructing the positions of hadronic interactions, also known as primary
vertices, at hadron collider experiments. We use a 2036 qubit D-Wave quantum
annealer to perform track clustering in a limited capacity on artificial events
where the positions of primary vertices and tracks resemble those measured by
the Compact Muon Solenoid experiment at the Large Hadron Collider. The
algorithm, which is not a classical-quantum hybrid but relies entirely on
quantum annealing, is tested on a variety of event topologies from 2 primary
vertices and 10 tracks up to 5 primary vertices and 15 tracks. It is
benchmarked against simulated annealing executed on a commercial CPU
constrained to the same processor time per anneal as time in the physical
annealer, and performance is found to be comparable for small numbers of
vertices with an intriguing advantage noted for 2 vertices and 16 tracks
Significance of radiation heat transfer on cooling performance of transformer radiator
The article demonstrate significance
of radiation heat transfer on cooling
performance of radiators used in power
transformers with air natural cooling
configuration using analytical calculations
and computional fluid dynamics
simulations on two different case
studies. Convective and radiative heat
transfer mechanisms are modelled on
a single radiator and a good agreement
with the experimental measurement
results is observed. The radiation contributes
21.3 % of total heat dissipation
and thus has a significant impact on
overall heat dissipation and cannot be
neglected. This study will be useful –
for the transformer designer – to point
on the relevance of the radiative heat
transfer in cooling
Reductive Biotransformation of Ethyl Acetoacetate: A Comparative Studies using Free and Immobilized Whole Yeast Cells
Bioreduction of ethyl acetoacetate with free and immobilized yeast whole cell was achieved by using water and sucrose combination. After detachment from immobilized beads under basic condition, the corresponding ethyl(S)-(+)-3-hydroxybutanoate was isolated with 98 to 100% yield. Immobilized beads of yeast whole cell were prepared at different temperature which affects the morphology and physiology of the beads for the diffusion of the enzyme, which shown the maximum conversion of the substrate to products as compared to the free yeast whole cell
Technology transfer in pharmaceutical industry- A Review
The objective of this review article is to study how technology is transferred in pharmaceutical industry. The article attempts to discuss about the technology transfer process, importance of technology transfer, reasons for using technology transfer, policy approaches of technology transfer, effective factors in technology transfer, Facets of technology transfer, goals of technology transfer, steps involved in technology transfer, barriers of technology transfer and the issues involved in the technology transfer in the pharmaceutical industry. The transfer may be said to be successful if the receiving unit and the transferee can effectively utilize the technology for business gain. The transfer involves cost and expenditure that should be agreed by the transferee and transferor. The success of any particular technology transfer depends upon process understanding or the ability to predict accurately the future performance of a process
Green Approach in Click Chemistry
The aim of the topic on click chemistry is used to synthesize various derivatives of 1, 2, 3-triazol-1-yl piperazine, 1, 2, 3-triazol-1-yl quinoxaline, one pot 1,2,3-triazole and bistriazole. These various synthesized compounds were biologically active such as antimicrobial, anti-oxidant, anticancer, antiviral, anti HIV and antitubercular activates. The heterocyclic compounds which are pharmacological active were synthesized by the Cu (I)-catalyzed Huisgen 1, 3-dipolar cycloaddition is a major example based on the click chemistry philosophy. The click chemistry in a broad sense is about using easier reactions to make compounds for certain functions of drugs. The click chemistry used as a green synthesis, because it allows the basic principles of green chemistry given by Anastas and Warner
