Statistical analysis of climatological data to characterize erosion potential : 6. joint precipitation and freezing events in eastern Oregon/Washington

Creator:: Istok, Jonathan D., Brown, Barbara G., Boersma, Larry, Katz, Richard W., and Murphy, Allan H.
Abstract:: When precipitation falls on frozen soil, serious soil loss can occur. In order to assign realistic probabilities to the occurrence of this condition for use in predicting erosion rates over long time periods, a technique for combining characteristics of precipitation and air temperature records is applied to hourly wet season...

A multiprocessor node for communication and control

Creator:: Atluri, Venkata Ram
Abstract:: This paper describes the design and implementation of "A multiprocessor node for communication and control" (MPCC). MPCC is a high speed, high performance local area network capable of performing real time control tasks. This is achieved by the concurrent operation of two 8051 microcontrollers, a dual port RAM and the...

Nitrate-nitrogen accumulation in the surface soil during the fallow period under different precipitation levels and tillage systems

Creator:: Senel, Atila Huseyin
Abstract:: The effects of different fallow moisture levels and tillage systems on the amount of nitrate-nitrogen accumulation in the 0-30 cm soil profile were studied. Fallow moisture treatments simulating typical dry, normal and wet precipitation cycles were established on trial plots. Data were obtained for nitrate-nitrogen, soil moisture and nitrogen mineralization...

Design and application of a microcomputer automated multielement flame atomic fluorescence instrument

Creator:: Neyzari, Shahrokh Ghaffari
Abstract:: An automated multielement flame atomic fluorescence (AF) spectrometer based on microcomputer control was constructed to determine four elements simultaneously. The instrument employs a multiple exit slit monochromator where the light from various exit slits is directed to a single detector with a mirrored funnel. Each element is excited to fluoresce...

Analytical and mechanistic studies of the chemiluminescence oxidation of hydroxy-containing compounds

Creator:: Vasquez de Montalvo, Socorro I.
Abstract:: This thesis is concerned with the development and use of routine analysis techniques based on chemiluminescence (CL) detection for: 1) ethanol in gin down to the 0.3% (v/v) level; 2) the antioxidants propyl gallate and BHA in lard to levels as low as 0.3 and 0.2 mg/L, respectively; 3) pyrogallol...

CTD observations in the coastal transition zone off Northern California from R/V Wecoma: July to August 1988

Creator:: Fleischbein, Jane, Schramm, Richard E., Huyer, Adriana, Kosro, P. Michael, Cowles, Tim, Krefft, Kevin, and Paulson, Clayton
Abstract:: Wecoma cruise W8807A was conducted in late July and early August 1988 as part of the Coastal Transition Zone project. CTD observations were made over a standard grid in the coastal transition zone off northern California between 37°N and 39.5°N that was occupied repeatedly during June, July and August; this...

Towed thermistor chain observations in JASIN

Creator:: Baumann, R. J., Paulson, Clayton A., and Wagner, J.
Abstract:: Observations of temperature and pressure between 10 and 70 m depth were taken with a towed thermistor chain during late August and early September, 1978, about 400 km northwest of Scotland as a part of the JASIN Experiment. The chain was usually towed at a speed of 3 mis around...

Evaluation of finite element techniques for soil reinforcement applications

Creator:: Berg, Ryan Robert
Abstract:: A literature review and a computer study are conducted to identify the requirements of finite element programs for the specific use of discrete analyses of reinforced soil structures. The utility of six commercially available programs are appraised with respect to the identified requirements. The results of the study are directed...
