METHODS AND TECHNIQUE FOR THERMOPOWER AND ELECTRICAL CONDUCTIVITY MEASUREMENTS OF THERMOELECTRIC MATERIALS AT HIGH TEMPERATURES [PDF]

Научно-технический вестник информационных технологий, механики и оптики, 2015
The principles and methods of thermopower and electrical conductivity measurements at high temperatures (100 – 1000 K) are reviewed. These two properties define the so-called power factor of thermoelect ric materials.

Effects of oxidation and hot corrosion in a nickel disc alloy [PDF]

, 2008
This paper describes work to study oxidation and hot corrosion damage in nickel disc alloy RR1000. Oxidation damage has been characterised via mass change data from thermogravimetric analyses at temperatures from 700 to 800 ºC and cyclic oxidation ...

The development of advanced creep constitutive equations for high chromium alloy steel (P91) at transition stress range [PDF]

Creep damage is a time-dependent deformation in metals under a constant stress at high temperature condition. Since the 1980s, high chromium alloy steel P91 (9%Cr-1%Mo-0.25%V) is highly demanded in high temperature industries (Saha, 2003).

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

FEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
