Integrated Electronic Transport and Thermometry at milliKelvin Temperatures and in Strong Magnetic Fields [PDF]
We fabricated a He-3 immersion cell for transport measurements of semiconductor nanostructures at ultra low temperatures and in strong magnetic fields. We have a new scheme of field-independent thermometry based on quartz tuning fork Helium-3 viscometry ...

Reinvestigating the Parabolic-Shaped Eddy Viscosity Profile for Free Surface Flows
The flow in rivers is turbulent. The main parameter related to turbulence in rivers is the eddy viscosity, which is used to model a turbulent flow and is involved in the determination of both velocities and sediment concentrations.

Probing viscoelastic properties of a thin polymer film sheared between a beads layer and quartz crystal resonator [PDF]
We report measurements of viscoelastic properties of thin polymer films of 10-100 nm at the MHz range. These thin films are confined between a quartz crystal resonator and a millimetric bead layer, producing an increase of both resonance frequency and ...

Suspended Sediments in Environmental Flows: Interpretation of Concentration Profiles Shapes
In environmental flows, field and laboratory measurements of suspended sediments show two kinds of concentration profiles. For coarse sediments, a near-bed upward convex profile is observed beneath the main upward concave profile.

Thermal-electrical analogy and inertia for thermal performance of building envelops [PDF]
For transient thermal performance of building envelops adequate parameters are needed to capture the time lag and decrement factor. It is surprising that, in the formal electrical analogy, "inertia" is not represented by same components in fluid ...

The preservation of quartz grain surface textures following vehicle fire and their use in forensic enquiry [PDF]
During a terrorist trial, dispute arose as to whether the temperature produced in a car fire was sufficient to destroy quartz grain surface textures.

Polymorphism, superheating, and amorphization of silica upon shock wave loading and release [PDF]
We present a detailed and quantitative examination of the thermodynamics and phase change mechanisms (including amorphization) that occur upon shock wave loading and unloading of silica.

Using multiple measures of teaching quality to strengthen teacher preparation
We argue that teacher preparation programs considering approaches to assess teaching quality should choose measures that appropriately represent the complexity of teaching, have formative value in supporting teacher candidates develop as highly qualified
