Mercury and stable isotope (δ¹³C and δ¹⁵N) trends in decapods of the Beaufort Sea

To date, limited data are available on mercury (Hg) concentrations in Arctic benthos. It is important that we establish baseline Hg concentrations in benthic communities to improve our understanding of Hg with...

Recruitment and sequencing of different degrees of freedom during pointing movements involving the trunk in healthy and hemiparetic subjects

 Previous studies have shown that in neurologically normal subjects the addition of trunk motion during a reaching task does not affect the trajectory of the arm endpoint. Typically, the trunk begins to move b...

Thermal and Electronic Properties of An AICoFeCr Approximant of the Decagonal Phase

We have studied the dependence versus nominal composition and temperature of the thermal conductivity in the AlCoFeCr system close to the region where an approximant of the decagonal phase forms. This compound...

Inverse resolution of the heat-transfer equation with internal heat source: Application to the quenching of steels with phase transformations

A method is described for calculating the time dependence of the temperature and heat flux (on heating and cooling) at the surface of a solid body. For a given ambient temperature and a known time-temperature ...

Techniques of Quenching

Immersion cooling, refers to direct cooling (usually by a liquid quench) of the metal from its heat austenitizing temperature to, or at least to near, ambient temperature. This is the most commonly used method...

Quench Cooling Optimisation for Aluminium Alloys

By numerical thermal and mechanical calculations (taking into account the variation of the thermophysical properties of the alloy with temperature), an optimum quench cooling path has been defined. Opposite to...
