2 μm average sized silicon powder was nitrided with 90% N₂/10% H₂ in a
fluidized-bed reactor, operated at 1200°C, 1250°C and 1300°C. To fluidize silicon
powder, alumina particles with an average size of 300 μm were used as an inert fluidizing
conditioner. The feasibility and operating conditions of the fluidization...
Pacific whiting (Merluccius productus) is the most abundant
groundfish species off the California, Oregon and Washington Coasts.
The fish are mainly used as a raw material for the production of surimi.
However, it is not economically wise to depend only on one product.
There is a need to diversify the...
The goal of this thesis was to determine the physiological mechanisms that link adverse preplanting treatments of Douglas-fir, such as exposure and root pruning, to the phenomenon of transplanting shock. The objective of experiments 1 and 2 was to measure the effect of exposure and pruning on the physiology and...
