The initiation of ice in an isolated orographic wave cloud was compared with expectations based on ice nucleating aerosol concentrations and with predictions from new ice nucleation parameterizations applied in a cloud parcel model. Measurements of ice crystal number concentrations were found to be in good agreement both with measured...
During the Ice in Clouds Experiment–Layer Clouds (ICE-L), aged biomass-burning particles were identified within two orographic wave cloud regions over Wyoming using single-particle mass spectrometry and electron microscopy. Using a suite of instrumentation, particle chemistry was characterized in tandem with cloud microphysics. The aged biomass-burning particles comprised ~30%–40% by number...
During the Ice in Clouds Experiment‐Layer Clouds (ICE‐L), dry lakebed, or playa,
salts from the Great Basin region of the United States were observed as cloud nuclei in
orographic wave clouds over Wyoming. Using a counterflow virtual impactor in series with
a single‐particle mass spectrometer, sodium‐potassium‐magnesium‐calcium‐chloride
salts were identified as...
Ice concentrations in orographic wave clouds at temperatures between −24° and −29°C were shown to be related to aerosol characteristics in nearby clear air during five research flights over the Rocky Mountains. When clouds with influence from colder temperatures were excluded from the dataset, mean ice nuclei and cloud ice...
This work details the development of 3D printed TPU pneunet actuators for use in apple picking for agricultural soft robotics. These actuators increase the force capabilities of soft pneunets and simplify manufacturing. Grippers based on these actuators are ideal for apple picking because they are compliant, yet exert sufficient force...
This 1957 progress report will be concerned with results of the use of herbicides on pole beans, sweet corn, and table beets in trials at Corvallis. The plots were evaluated for effectiveness of weed control by these herbicides as well as their effects on yield. These results are to be...
This thesis is based on a two-part study that analyzes the cultural and linguistic characteristics of the Hawaii student population at Oregon State University (OSU). I designed and conducted a survey among Hawaii students at OSU. Then I interviewed ten Hawaii students who self-identified as Hawaii Creole English (a.k.a. Pidgin)...
