In silico evaluation of the thermal stress induced by MRI switched gradient fields in patients with metallic hip implant [PDF]

open access: yes, 2019
This work focuses on the in silico evaluation of the energy deposed by MRI switched gradient fields in bulk metallic implants and the consequent temperature increase in the surrounding tissues. An original computational strategy, based on the subdivision

Temperature Gradient Generation and Control [PDF]

open access: yes, 2008
In today’s microfluidic technology, electrokinetic transport is used to perform many chemical and biological analyses in lab-on-a-chip devices, such as clinical diagnoses, DNA scanning, cell manipulation, cell patterning, and molecular detection. Due to the presence of an electrical potential gradient in electrokinetic transport, Joule heating is a ...

Cave airflow mechanism of a crevice-type cave: A case study from Czechia

open access: yesInternational Journal of Speleology, 2020
At present, crevice-type caves are investigated mainly by means of geomorphic and geophysical methods. Microclimatic research of this type of caves is underrepresented and is often limited to temperature and humidity measurement only.

Temperature gradient driven lasing and stimulated cooling

open access: yes, 2012
A laser can be understood as thermodynamic engine converting heat to a coherent single mode field close to Carnot efficiency. From this perspective spectral shaping of the excitation light generates a higher effective temperature on the pump than on the ...

Effect of defects on the motion of carbon nanotube thermal actuator

open access: yesNanotechnology Reviews, 2019
Using molecular dynamics simulations, we investigate the movement behavior of double-walled carbon nanotube containing single atom vacancy defect and Stone–Wales defect. The carbon nanotube thermal actuator consists of a short outer tube and a long inner

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Selected, optimum, pessimal and tolerant temperatures in cladocera Simocephalus vetulus (O.F. Müller, 1776)

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2015
Temperature election and avoidance are investigated in Simocephalus vetulus (O.F. Müller 1776), caught during the vegetative season in the littoral of the Rybinsk Reservoir.
