The effects of clipping on the vigor of big game browse plants and related studies in the Arizona chaparrel

Creator:: Neff, Don J.
Abstract:: A five-year clipping experiment was conducted to determine maximum sustained utilization levels for three big game browse plant species in central Arizona. The three species were mountain-mahogany (Cercocarpus breviflorus) and desert ceanothus (Ceanothus Greggii) in the chaparral type, and cliff-rose (Cowania mexicana var. Stensburiana) in the pinyon-juniper type. Experimental treatments...

Survival and development of the flat-headed fir borer in forest residues as affected by host and microclimatic conditions

Creator:: Scott, Donald Wayne
Abstract:: The purpose of this study was to examine various host and microclimatic influences affecting the survival and development of the flatheaded fir borer, Melanophila drummondi (Kirby) in Douglas fir, Pseudotsuga menziesii (Mirbel) Franco residues. It also expands current knowledge of the biology, bionomics, life history, ecology, and biotic potential for...

The influence of mold contamination, processing and maturity on the volatiles of the strawberry, Fragaria ananassa Duch.

Creator:: Amos, James Franklin
Abstract:: The effects of mold level (Botrytis cinerea), processing method (fresh, individually quick frozen (IQF), frozen sugared sliced (FSS), freeze dried (FD), canned, and preserves), and maturity (underripe, normal, and overripe) and strawberry volatiles were analyzed by gas liquid chromatography (GLC) using on-column entrainment of headspace volatiles in aqueous extracts. Computerized...

Some complex numerical integrations of the Schwarz-Christoffel transformation and application to potential flow

Creator:: Wassmuth, Robert Henry
Abstract:: The Schwarz-Christoffel transformation is used to map simply connected polygons onto the upper half plane and can be applied to problems in which the validity of Laplace's equation is assumed. However the direct integration of the resulting complex integral is often not possible and some approximate method must be used....

A chorological analysis of the grass balds in the Oregon Coast Range

Creator:: Aldrich, Frank T.
Abstract:: Detailed phytosociological and physical data were gathered from six grass-fern balds in the Oregon Coast Range, Monmouth Peak, Grass Mountain, Prairie Peak, Roman Nose Mountain, Tyee Mountain, and Saddle Mountain. Panchromatic and color infrared air photography guided sampling within individual balds. The resultant floristic data was manipulated by a Braun-Blanquet...

Heat induced compounds in milk

Creator:: Scanlan, Richard A.
Abstract:: Milk, preheated at 82°C for 30 minutes, was heated to 146°C for four seconds (UHT-treated) and cooled to 5°C in a tubular heat exchanger. Immediately after heat treatment, 20 gallons of heated milk were vacuum distilled at 30°C in a semi-continuous, reduced pressure glass apparatus. Twenty gallons of non-heated milk...

Reducing sediment production from forest roads during wet-weather use

Creator:: Toman, Elizabeth Myers
Abstract:: Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...
