Efficacy of entomopathogenic fungi for control of the cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae)

Creator:: Snelling, Jane E.
Abstract:: The cabbage maggot, Delia radicum (L.) (Diptera: Anthomyiidae) is a serious pest of cruciferous crops (i.e. broccoli, cabbage, turnip, rutabaga) in North America and Europe (Coaker and Finch, 1971; Whistlecraft et al., 1985). The adult flies lay eggs around the base and in cracks at the soil surface around wild...

Genetic analysis of interactions between the plant hormones auxin and ethylene

Creator:: Barckley, Kristi K.
Abstract:: Auxin and ethylene regulate many important aspects of plant growth and development and are essential to the plants survival. They help regulate such diverse processes as cell elongation, growth of adventitious roots, fruit growth, germination, and a variety of other processes. Few studies have examined how the hormones auxin and...

Does teacher-child relationship quality predict observed child engagement of teacher?

Creator:: McClain, Joanna L.
Abstract:: The quality of relationships in early childhood have lasting effects on children’s academic and behavioral success. Teacher report is the most widely used measure to assess the quality of the teacher-child relationship, however teachers are often biased by the child’s behavior. Observed quality of the relationship may illustrate differences in...

Biological control of insects using entomopathogenic nematodes

Creator:: Bezdek, Tanya M.
Abstract:: Biological control is the action of predators, parasitoids, or pathogens to maintain a pest organism's population at lower numbers than would occur in the absence of the agent. Entomopathogenic nematodes can be used as biological control agents for insect pests. These nematodes infect insects and release a toxic bacterium that...

Evaluating desiccated cyanobacteria Aphanizomenon flos-aquae for use as a biofertilizer on Swiss Chard

Creator:: Turk, Douglas E.
Abstract:: Non-toxic species of desiccated blue-green algae, or cyanobacteria, may offer potential for use as a fertilizer on irrigated crops. Here, the non-toxic cyanobacteria species Aphanizomenon flos-aquae (AFA), collected from Upper Klamath Lake, Oregon, was evaluated for use as a biofertilizer in a controlled experiment on Swiss chard “Bright Lights” (Beta...

Bacteria in Milk

Creator:: Jackson, Laura Estella and Hess, Ruth Jeannette
Abstract:: "Bacteriology is such a broad subject that a life-time spent in its perusal would fail of an entire knowledge of the subject, so the authors have chosen a field which is certainly one that ought to interest every individual because it pertains to milk, one of the most important foods...

What Disrupts Cycles of Poverty? Examining the Effect of Family Background and Educational Attainment on Receiving Public Assistance with Multivariate Regression

Creator:: Vargas, Patricia I.
Abstract:: Understanding poverty as a state of being poor with regard to concretely being unable to meet basic needs such as water, food, clothes, shelter, and essential services (e.g., sanitation, health, and education), its concerted study in the United States not only stands tandem with constitutionally upheld values such as equality...

Constraining the origin and influence of andesite in the Purico ignimbrite, N. Chile

Creator:: Lapinski, Sarah L.
Abstract:: A feature of large continental magmatic systems is voluminous dacite ignimbrites erupted from upper crustal magma reservoirs. In the Altiplano Puna Volcanic Complex (APVC) of the Central Andes, a major ignimbrite and caldera plateau, magma systems are found to be long-lived and remarkably homogeneous requiring that they be maintained by...

Comparison of the Accuracy and Applicability of Forebody Wake Effect Models for Parachute System Design

Creator:: Kemling, Gabriel H. and Blunck, David L.
Abstract:: The forebody wake effect (FWE) is important to consider when designing parachute systems because it can affect parachute performance. Parachutes work by altering the aerodynamic properties of an attached forebody to control a descent. The FWE can reduce parachute drag, causing the system to descend faster than desired. This drag...
