We examined the composition and structure of forest communities in a 3700 ha watershed in relation to environmental gradients and changes in land management practices. We identified four mixed-conifer forest types dominated by different combinations of Abies concolor, Picea pungens, Pinus ponderosa, Populus tremuloides, and Pseudotsuga menziesii, and a(More)
Premium wine production is limited to regions climatically conducive to growing grapes with balanced composition and varietal typicity. Three central climatic conditions are required: (i) adequate heat accumulation; (ii) low risk of severe frost damage; and (iii) the absence of extreme heat. Although wine production is possible in an extensive climatic(More)
A pre-requisite in the setting and enforcement of regulatory limits for exposure to thorium in the workplace is that thorium and its progeny can be accurately measured. Literature surveys have shown that the majority of thorium measurements were performed using either a radiochemical technique, such as alpha or gamma spectroscopy, or ICP-MS. For many(More)
The monitoring of radionuclides in the nuclear industry has been recognized as the most straightforward way of assessing health and safety issues associated with the exposure of the workforce to potentially harmful radiation doses. Much of this is achieved by measurements in the workplace itself and by the bioassay and monitoring of workers in the industry.(More)
The increasing demand for universities to produce engineers from diverse backgrounds has brought about the need for special programs that encourage the recruitment and retention of underrepresented groups. The Women in Applied Science and Engineering (WISE) Program at Arizona State University provides summer recruiting programs that serve to bridge(More)
