Two summertime days were investigated, 27 and 28 June 1973,
to observe the changes in the environment that led to the severe hailstorm
on 28 June in the National Hail Research Experiment (NHRE)
network, Colorado. Within the network thermodynamic analyses
revealed the 28th to have:
(1) Above-average low-level moisture.
This paper defends a reading of Hennan Melville's Moby-Dick that elevates
Ishmael's status from mere narrator of Ahab's tragedy to that of protagonist of his own
story, a novel of epistemological seafaring. As a metaphysical quester, Ishmael provides
the novel's only reliable and complex vision of the condition of man...
The lentil strain of pea seedborne mosaic virus, PSbMV-L, was
distinguished from the standard isolates of PSbMV by a natural inoculum
reservoir in lentil seed and by separate resistance genes in Pisum
and Lens. PSbMV-L was intermediate in symptom severity between the
standard and New Zealand isolates of PSbMV.
The purpose of this article is to explore student reasoning with regard to problems in logic, particularly those related to the Principle of Mathematical Induction (PMI). The five case studies presented build off of work done by other researchers, most notably Dubinsky and Harel, who both looked at how students'...
Zinc Sulfide (ZnS) thin film, with a wide band gap, has been used for many applications, such as buffer layer for CIGS solar cells, light emitting diodes and thin film electroluminescent devices.
In this work, ZnS thin films were prepared using two different deposition processes. In the first method, ZnS...
The rapid decline of marine ecosystems worldwide and the failure of traditional single species management pushed for the development of ecosystem-based conservation measures such as marine protected areas (MPA) to slow the loss of marine biodiversity. One approach to MPA creation advocates targeting marine megafauna (e.g., marine mammals, seabirds, sharks,...
As microelectronic parts trend smaller so do their solder joints. The surface finish on a copper pad is expected to become a significant part of the total solder joint volume and therefore affect mechanical properties of the smaller solder joints. Two sample geometries and four different surface finishes for tin-silver-copper...
The response of sweet corn (Zea mays L. var. rugosa cultivar
Jubilee) to 12 populations and four nitrogen rates was studied in a
field experiment. Populations ranged from 43, 904 to 329,800
plants/ha with nitrogen levels ranging from 0 to 224 Kg/ha. A systematic
spacing design was used. Plant height,...
Contamination of recreational and shellfish waters with fecal pollution is a
major water quality issue with associated economic impacts and human health risks.
Reliable fecal source identification and rapid, quantitative analyses are essential
components of risk assessment. Enteric bacteria that are endemic to specific hosts
have a potential role as...
