CRYO-ENGINEERING IN THE NUCLEAR ROCKET PROGRAM [PDF]
, 1963 Among the many remarkable technological achievements which have enriched our lives in the years since World War II, few have been more exciting to the imagination than the recent spectacular developments in the field of rocketry. Rocket systems are now available, as we all know, with sufficient power to permit mankind to take an initial step toward an ...

Resource redeployment as an entry advantage in resource‐poor settings
Strategic Management Journal, EarlyView.Abstract Research Summary Scarcity of productive factors poses a challenge for firms entering underdeveloped regions. We theorize that incumbent firms can overcome scarcity of skilled human capital in local labor markets by redeploying workers from existing units.

Small, EarlyView.A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...
