Title of Document: Chemotherapeutic Treatment Options to Manage Xylella fastidiosa in Shade Trees Darren DeStefano Master of Natural Resource Sciences 2005 Directed By: Associate Professor Joseph Sullivan Natural Resource Sciences and Landscape Architecture Xylella fastidiosa is a fastidious, xylem-limited, broad spectrum, bacterial plant pathogen native to the Americas, causing substantial eco...

One-sided information makes a misleading impact. It must therefore be requisitely holistic. Information from an assessment of the creditworthiness of an enterprise is the same case. But the requisite holism is much less easy to attain than one-sidedness. Therefore this contribution explains creditworthiness assessment and puts it in the shade of our version of systems thinking. We find that it ...

Soil organic C (SOC) and total soil N (TSN) sequestration estimates are needed to improve our understanding of management influences on soil fertility and terrestrial C cycling related to greenhouse gas emission. We evaluated the factorial combination of nutrient source (inorganic, mixed inorganic and organic, and organic as broiler litter) and forage utilization (unharvested, low and high catt...

Design experiences can provide valuable opportunities for learners to improve their understanding of both science content and scientific practices. However, the implementation of design-based science learning (DBSL) in classrooms presents a number of significant challenges. In this article we present two significant challenges, bridging the design-science gap and overcoming time and material co...

The behavioural responses to light in the ciliate Paramecium bursaria Focke, which normally contains hundreds of the symbiotic green alga Chlorella in its cytoplasm, were analysed quantitatively to clarify the mechanisms governing photoreception in the cell. P. bursana was found to possess three kinds of photoreceptor systems for (1) the step-up photophobic response (system I), (2) the step-dow...

This article is focused on the infrared heating of shell metal moulds and optimization of temperature field on the surface of the mould. The upper part of the mould is heated by infrared heaters, and after the required temperature is attained the inner part of the mould is sprinkled with special PVC powder. The moulds are made of aluminium or nickel alloys. The described mathematical model allo...

This study developed an analytical procedure based upon a spectral unmixing model for characterizing and quantifying urban andscape changes in Indianapolis, Indiana, the United States, and for examining the environmental impact of such changes on land urface temperatures (LST). Three dates of Landsat TM/ETM+ images, acquired in 1991, 1995, and 2000, respectively, were tilized to document the hi...

Understanding howmoose (Alces alces (L., 1758)) are affected by temperature is critical for determiningwhy populations have recently declined at the southern extent of their North American range.Warm-season heat-stress thresholds of 14 and 20 °C are commonly used to study moose, but the variable response of free-ranging moose to temperatures above these thresholds suggests thatmoosemay bemore t...

Pinus halepensis Mill. is a Mediterranean pioneer forest species with shade intolerance features. The 15 purpose of this study is to better understand how stand fertility and allelopathic properties of adult trees influence 16 shade acclimation of saplings. Crown growth and morphological plasticity were studied under different light, 17 fertilization, and allelopathic conditions in a nursery ex...
