Investigation Of Hydrocarbon Phytoremediation Potential Of Lupinus Chamissonis In Laboratory Microcosms, Wendy Martin, Yarrow M. Nelson, Kenneth Hoffman

Civil and Environmental Engineering

Controlled laboratory microcosms were used to research the phytoremediation potential of lupines (Lupinus chamissonis) for hydrocarbon-contaminated groundwater at a former oil field near Guadalupe, California. During oil production in the Guadalupe Oil Field, a kerosene-like hydrocarbon mixture was used as a diluent to improve the flow of the heavy crude oil. Leaking tanks and pipes resulted in diluent contamination in the soil and groundwater. Native plant species were planted at a pilot-scale field site to investigate the feasibility of using phytoremediation to remediate the groundwater contamination. In the field, biological and hydrological factors make it difficult to determine the specific …

A New Method For Melt Detection On Antarctic Ice-Shelves And Scatterometer Calibration Verification, Lukas Brad Kunz

Theses and Dissertations

Ku-band dual-polarization radar backscatter measurements from the SeaWinds on QuikScat scatterometer and microwave radiometer measurements from the Special Sensor Microwave/Imager (SSM/I) are used to determine periods of surface melt and freeze in the Antarctic ice-shelves. The normalized radar backscatter (sigma-0) and backscatter polarization ratio (PR) are used in the maximum likelihood estimation of the ice-state. This method is used to infer the daily ice-surface conditions for 25 selected study points located on the Ronne, Ross, Larsen, Fimbul, Amery, and Shackleton Ice-shelves. The temporal and spatial variations of the radar response are also observed for various neighborhood sizes surrounding each given …

Department of Geological and Mining Engineering and Sciences Publications

Pinatubo's 15 June 1991 eruption was Earth's largest of the last 25 years, and it formed a substantial volcanic cloud. We present results of analysis of satellite-based infrared remote sensing using Advanced Very High Resolution Radiometer (AVHRR) and TIROS Operational Vertical Sounder/High Resolution Infrared Radiation Sounder/2 (TOVS/HIRS/2) sensors, during the first few days of atmospheric residence of the Pinatubo volcanic cloud, as it drifted from the Philippines toward Africa. An SO₂-rich upper (25 km) portion drifted westward slightly faster than an ash-rich lower (22 km) part, though uncertainty exists due to difficulty in precisely locating the ash cloud. …

Processing And Optimization Of Natural Fiber Reinforced Composites Using Date Palm Fibers, Khalifa Musabbeh Suwaidan Hamad Al-Kaabi

Theses

During the last twenty years, ecological concerns have resulted in a renewed interest in natural materials. Composite materials usually depend on using man-made fibers as the reinforcing element. The possibility of using natural fibers instead of synthetic fibers is gaining acceptance among users. This work aims to investigate the possibility of extracting natural fibers from date palm trees to be used as reinforcement with polymeric materials. The objective was achieved by characterizing fibers through different chemical, physical and mechanical tests and using different treatment methods in order to modify the fiber properties.

The Use Of Monitoring Data And Geologic Documentation As A Basis For Defining Rock Mass Behavior Types For Tunnelling, Edward A. Button, Wulf Schubert, Gunter Riedmueller

International Conference on Case Histories in Geotechnical Engineering

The use of geodetic surveying to measure the absolute 3-D tunnel displacements has provided new opportunities to evaluate the system behavior and interpret the rock mass behavior associated with tunneling. For a meaningful case history evaluation it is necessary to have consistent and quality documentation covering the excavation and support sequence, the geological conditions, as well as the displacement measurements. Combing this data allows the rock mass behavior type to be evaluated. In contrast to many available rock mass characterization or classification procedures, the procedure introduced by the Austrian Society for Geomechanics within the Guideline for the Design and Construction …
