Some aspects of Western religious thought and man's use of land

Creator:: Bryant, Robert Edman
Abstract:: This study examines a limited number of selected themes in Judeo-Christian, or Western, religious thought and their implications for man's use of land, with the objective of discovering the influence of Western religion on attitudes toward nature and land. Five themes are examined: dominion of man; stewardship; contempt for, and...

Differential transmission of strawberry mottle virus by Chaetosiphon thomas Hille Ris Lambers and Chaetosiphon fragaefolii (Cockerell)

Creator:: Eulensen, Gustav Egon
Abstract:: The transmission of strawberry mottle virus (SMV) to Fragaria vesca L. by Chaetosiphon thomasi and C. fragaefolii was studied to determine differences between the two species. Acquisition, inoculation, and retention phases of transmission were described. In all phases, C. fragaefolii was found to be the more efficient vector. Mean transmission...

Life history of the Obscure Root Weevil, Sciopithes obscurus (Horn), on rhododendron

Creator:: Bell, Harry Thomas
Abstract:: The life history of the Obscure Root Weevil, Sciopithes obscurus (Horn), on Rhododendron was studied at four sites in the Willamette Valley. This research was conducted in an effort to provide information necessary to develop adequate methods to control this Curculionid pest on Rhododendron in the Willamette Valley. Five larval...

Examination of factors affecting larval mortality of the black vine weevil, Otiorhynchus sulcatus Fab., on container grown rhododendrons

Creator:: La Lone, Ralph Stanley
Abstract:: Two types of exogenous mortality factors, density-independent and density-dependent, were identified for the black vine weevil, Otiorhynchus sulcatus Fab., developing on container grown rhododendrons. The addition of the insecticide acephate, (O.S.- Dimethyl acetylphosphoramidothioate, Orthene®)75S) to the rhizosphere of rhododendrons in which larval O. sulcatus develop was categorized as a density-independent...

Aphid age and in-vector virus concentration as factors influencing pea enation mosaic virus transmission by the pea aphid

Creator:: Suharto, Hendarsih
Abstract:: The relationship between pea enation mosaic virus (PEMV) and aging pea aphids was studied. Although this research initially emphasized the relationship between the decline in the rate of PEMV transmission and the 'concentration of PEMV within pea aphids, aphid age was found to be the principle factor influencing transmission. Enzymelinked...

Aspect-dependent variations in regolith creep revealed by meteoric ¹⁰Be

Creator:: West, Nicole, Kirby, Eric, Bierman, Paul, and Clarke, Brian A.
Abstract:: Although variations in insolation and emergent feedbacks among soil moisture, vegetation, and soil cohesion are commonly invoked to explain topographic asymmetry that depends on aspect, few studies have directly quantified the efficiency of regolith transport along hillslopes of opposing aspect. We utilize meteoric ¹⁰Be concentrations in regolith (n = 74)...

A reconstruction of changes in land use/land cover in Vermont relative to sensitivity of surface waters to acidic deposition

Creator:: Clarke, Sharon Elaine
Abstract:: Patterns of land use/land cover explain some of the spatial variability in sensitivity of surface waters to acidic deposition. Historic changes in land use/land cover may further explain some of the spatial variability. A map of land use/land cover changes needs to be compiled before this relationship can be analyzed....

The design, construction and calibration of a low-energy, low exposure-rate ionization chamber

Creator:: Clarke, Arthur Porter
Abstract:: A low-energy, low-exposure-rate, guarded-field ionization chamber system with a sensitive volume of approximately 1040 cm³ and an exposure-rate range from 60 mR/h to less than 0.5 mR/h was designed, constructed and calibrated. The calibration was effected by constructing and calibrating a 60 cm³ volume transfer chamber of similar design against...

A study of the whole job (multi-position) approach as compared to the traditional (single-position) approach in the development of arc welding skills

Creator:: Stemmer, Roland Clarke
Abstract:: The major consideration of this study was the testing of the superiority of the whole or part method for developing basic arc welding skills. Data were also generated which facilitated investigation of: (1) the relationship of welding skill development to cognitive attainment of welding information as measured by welding proficiency...
