We report stenting of coarctation of an angulated right circumflex aortic arch (RCAA) using four Cheatham Platinum stents in a child with Goldenhar syndrome. Difficulties in measuring the accurate length of the curved and narrowed transverse aortic arch marked discrepancy between the luminal diameters of the long narrow transverse arch and wide descending thoracic aorta, increased displacement ...
The structure of an actively transcribing complex, containing yeast RNA polymerase II with associated template DNA and product RNA, was determined by electron crystallography. Nucleic acid, in all likelihood the "transcription bubble" at the active center of the enzyme, occupies a previously noted 25 A channel in the protein structure. Details are indicative of a roughly 90 degrees bend of the ...
[1] We perform two-dimensional dynamic models of strike-slip faults with a change in strike (a bend) over multiple earthquake cycles to examine the long-term effects of nonplanar fault geometry. A viscoelastic model (a proxy for off-fault deformation and tectonic loading) is introduced for the interseismic process to avoid pathological stress buildup around the bend. A finite element method wit...
A numerical experiment is carried out to study the suitability of two-dimensional (2D) depth-averaged modeling for bend-flow simulation, in which the geometry of the studied channel is rectangular. Two commonly used 2D depth-averaged models for bend-flow simulation are considered in this study of which the bend-flow model includes the dispersion stress terms by incorporating the assumption of s...
Using video recordings we have completed the first kinetic analysis of mushroom stem gravitropism. The stem became gravireceptive after completion of meiosis, beginning to bend within 30 minutes of being placed horizontal. Stem bending first occurred in the apical 15% of its length, then the position of the bend moved rapidly towards the base, traversing 40% of stem length in 2.5 h. Meanwhile, ...
Green synthesis of metal nanoparticles (NP) has emerged as a recent trend in green chemistry. However, their potential the field agriculture is yet underexplored. In this study, silver (Ag NPs) were synthesized by using fruit juice and peel extract Citrus maxima (Burm.) Merr. reducing capping agent. The nano-primed seeds Zea mays, Glycine max, Cicer arietinum showed enhanced germination rate up...
