A series of diversely substituted chalcones derived from a quinoline scaffold, e.g.(E)-3-(2-chloroquinolin-3-yl)-1-(2-hydroxyphenyl) Water Bottle prop-2-en-1-one and its pyrimidine analogues e.g.2-[2-amino-6-(2-chloroquinolin-3-yl)-5,6-dihydropyrimidin-4-yl]phenols have been prepared by condensation of 2-chloro-3-formyl quinoline with differently s
Ligusticum sinense is a popular herb in Chinese medicine.The circular double-stranded complete chloroplast genome of L.sinense was 146,342 bp in length, exhibiting a typical quadripartite structure.It contained a large single-copy region (LSC) of 91,788 bp, a small single-copy region (SSC) of 17,618 bp and two identical inverted repeat (IR) regions
A regularized linear programming problem of finding permissible air pollution emission rates for multiple sources of a number of industrial plants is formulated in the paper.The objective of solving that problem is to obtain the maximum profit under Breast Pump Accessories emission rate limits and conditions of proportional distribution of permissi
This study focuses on a high-altitude long-endurance (HALE) joined-wing configuration UAV and completes a preliminary structural design based on aircraft design indices and the fundamental principles of aircraft structure design.Based on the preliminary structural design scheme and aerodynamic shape, a structural finite element model and a vortex l
