A study on the carotenoids of wild-type and mutant strains of the alga, Scenedesmus obliquus

Creator:: Williams, Janet Lynn
Abstract:: The primary objective of this thesis is to study, characterize and compare four types of Scenedesmus obliquus pigment mutants with the wild-type strain. The specific nature of the carotenoids synthesized in both heterotrophically and myxotrophically-grown cells, Hill reaction activity, photoreduction activity, and total photosynthetic activity of these cells are examined....

Characterization of strains of Scenedesmus resistant to the herbicide DCMU, (3-(3,4-dichlorophenyl)-1,1-dimethylurea)

Creator:: Smith, Muriel K.
Abstract:: Three DCMU resistant mutants of the green alga Scenedesmus obliquus D₃ are characterized. The mutants exhibit a ten fold greater resistance to DCMU than the wild type strain; this is comparable to the level of DCMU resistance detected in other DCMU resistant algae. In whole cell reactions, as well as...

The carotenoids and membrane polypeptides of the light harvesting complex of mutants of Scenedesmus obliquus deficient in chlorophyll

Creator:: Maggard, Sharon P.
Abstract:: The photosynthetic activities, the pigmentation and the chloroplast membrane polypeptides of several mutants of the green alga, Scenedesmus obliquus, with complete or limited deficiencies in the light-harvesting complex of photosystem II are characterized and compared to those of the normal phenotype.. The principal phenotype examined in this study, K0 -9,...

Spinach peroxidase and the photo-oxidation of manganese by isolated chloroplasts

Creator:: McKenna, John Michael
Abstract:: Manganese has been known to be essential for photosynthesis for almost 30 years. Subsequent experimentation indicated a definite function for manganese in oxygen evolution. However, the mode of action of manganese and further localization of its site of action have not been determined. Ten years ago it was demonstrated that...

Assessing the Thermal Sensitivity and Stormflow Response of Headwater Stream Temperatures: A Seasonal and Event-scale Exploration in Northern California, USA

Creator:: Wissler, Austin D.
Abstract:: Mountainous headwater streams make up ~80 % of stream length globally and are strongly connected with catchment hillslopes and riparian areas, which can influence water quantity, quality, and availability for downstream uses. Accordingly, effective management of headwater streams and riparian zones to maintain desired ecosystem services downstream is critical, particularly...

Field and laboratory strength analysis of a forest road in NW Oregon and its association with the formation of ruts

Creator:: Bord, Andrea J.
Abstract:: A one-mile section of a newly constructed forest road in Northwest Oregon was analyzed for various aspects of subgrade and surface strength and their association with the formation of ruts during the first hauling season. Field and laboratory tests were completed on the road and the road materials to determine...

Using Acoustic Measurements and Inventory Data to Estimate Stiffness in Standing Douglas-Fir Trees

Creator:: Delgado Trejo, Jorge Luis
Abstract:: Total US lumber production in 2011 was 77.9 million cubic meters. Its primary use was for housing and construction. There is a growing concern that the structural properties for wood are being reduced as trees are harvested at much younger ages as the wood supply shifts from older to younger...

Recursive least-squares smoothing with constant or factorial weights

Creator:: Bishop, Chester Oliver, Jr.
Abstract:: This thesis develops recursion formulas for least-squares data smoothing with regard to four classes of functions: linear, quadratic, exponential and trigonometric, which in a linear fashion involve 2, 3, 2 and 2 parameters respectively. The term recursion implies here that the estimates for the parameters of the preceding fit are...
