Effects of Secondary Injection on the Cross Flow Induced Vibration of a Single Cylinder

Journal of King Saud University: Engineering Sciences, 1991
This paper represents an experimental investigation on the effect of a secondary injection in the vicinity of an elastically mounted smooth cylinder, on the flow induced vibration of such cylinder with the possibilities of using such injection for ...

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Relation between vibrotactile perception thresholds and reductions in finger blood flow induced by vibration of the hand at frequencies in the range 8–250 Hz

, 2014
Purpose: this study investigated how the vasoconstriction induced by vibration depends on the frequency of vibration when the vibration magnitude is defined by individual thresholds for perceiving vibration [i.e.

New developments in rain–wind-induced vibrations of cables [PDF]

, 2010
On wet and windy days, the inclined cables of cable stayed bridges can experience large amplitude, potentially damaging oscillations known as rain-wind-induced vibration (RWIV).

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Importance of Added Mass and Damping in Flow-Induced Vibration Analysis of Tubes Bundle: An Overview [PDF]

Mehran University Research Journal of Engineering and Technology, 2012
Flow-induced vibration is of prime concern to the designers of heat exchangers subjected to high flows of gases or liquids. Excessive vibration may cause tube failure due to fatigue or fretting-wear.

Characteristics and evaluation method of flow-induced vibration at tee connection caused by high velocity

Nihon Kikai Gakkai ronbunshu, 2014
In the process plant, random vibration excited by the turbulence generated at tee connection might cause problem such as piping damage. In general, the beam mode piping vibration is known to be excited when the internal flow of the piping is the severe ...
