Commissioning of ADAC Pinnacle for IMRT utilizing solid compensators

Creator:: Brumley, Willis E.
Abstract:: Use of solid compensators is a very effective means of implementing IMRT on any linear accelerator. The standard practice has been IMRT delivery using accelerators equipped with multi-leaf collimators (MLC’s). Truth is the addition of MLC’s to an accelerator is quite expensive. Previous studies have shown solid compensators to have...

Vitamin E effects on sterility of White Leghorn males following prolonged vitamin E deficiency

Creator:: Friedrichsen, Janet Valerie
Abstract:: One group of four adult White Leghorn male chickens was fed a diet containing 7.3% linoleic acid and 32.4 mg/ kg of added vitamin E (group IV) for 50 weeks which was designated as the positive control. A second lot (group I) containing 14 males received the same level of...

Estimates of genetic variance and heterosis in F₁ winter x spring barley crosses (Hordeum vulgare, L.)

Creator:: Harrabi, Moncef Mohamed
Abstract:: Four winter and four spring barley cultivars along with their F₁ hybrids were grown on the Hyslop Agronomy Farm near Corvallis, Oregon, a high rainfall site (over 1000 mm annually) located in the Willamette Valley. The experiment consisted of four replications. Ten seeds of each F₁ and parents were seeded...

Association of selected traits with visual selection for yield in wheat (Triticum aestivum, L. em Thell.)

Creator:: Marciniak, Michael E.
Abstract:: Visual selection for grain yield may be a limiting factor in identifying superior yielding genotypes in a breeding program. This investigation was conducted (1) to compare the effectiveness of visual selection for grain yield by three selector groups representing different levels of plant breeding experience, and (2) to examine the...

Response of winter wheat (Triticum aestivum L. Em. Thell) to nitrogen and chloride fertilization in the presence of take-all root rot (Gaeumannomyces graminis var. tritici Walker)

Creator:: Maatougui, Mohamed El Hadi
Abstract:: Response from nitrogen and chloride fertilization was measured in field experiments on winter wheat (Triticum aestivum L. Em. Thell. var. 'Stephens' and 'Yamhill') grown in western Oregon in an environment with a range of susceptibility to take-all root rot (Gaumannomyces graminis var. tritici Walker). Cropping sequences and expected disease severity...

Effects of three herbicides on yields of five cultivars of winter wheat (Triticum aestivum L. em Thell)

Creator:: Yahyaoui, Amor
Abstract:: With the development of new selective herbicides and the frequent change in commercial wheat cultivars, information is needed as to the possible interaction between cultivars and herbicides. The responses of five genotypically diverse wheat cultivars (Bezostaya, Daws, Maris Hobbit, Stephens and Yamhill) to diuron [3-(3,4-dichloropheny1)-1,1- dimethylurea], diclofop methyl 2-[4-(2,4-dichlorophenoxy)phenoxy] propanoate...

Association between length of grain filling period and grain yield in two wheat populations (Triticum aestivum L. em Thell.)

Creator:: Min, Hwang Kee
Abstract:: The objective of this study was to determine interrelationships among agronomic traits in early and late maturing populations. Two populations were obtained from the crosses, Roussalka/Tesopaco 76 and Yamhill/Aspen. Seeds were space planted with split plot design and nine agronomic traits were observed. In comparative studies between early and late...

Photographic analysis of buoyant stack plumes in a laboratory model of the turbulent mixed layer

Creator:: Hukari, Neil F.
Abstract:: Four buoyant plumes were produced within a laboratory convectively mixed layer from a source height of about z[subscript s] = 0.15 h, where h is the height of the convectively mixed layer. The projected images of these plumes in the X-Z plane were analyzed using a densitometer (photomultiplier tube) to...

Estimates of heterosis in winter/winter, winter/spring, and spring/spring crosses of barley (Hordeum vulgare L.)

Creator:: Oakley, Stephen Roland
Abstract:: Previous work indicated a substantial heterotic expression for grain yield existed within winter/spring hybrids of barley, This research was a continuation for the comparison of the expression of heterosis within winter/spring hybrids to the heterotic effect produced among the winter and among the spring parents. The F₁ and F₂ progenies...
