To the chagrin of his American comrades, Washington Irving would spend much of his life in Europe as a writer and cross-cultural explorer, including a stay in the halls of the Alhambra. This experience led to the completion of Tales of the Alhambra (1832), a collection of sketches, anecdotes, and...
The tosylhydrazones of 2-heptanone, 4,4-dimethy1-2-
heptanone, 6-heptyn-2-one and 4,4-dimethy1-6-heptyn-2-
one were synthesized and decomposed under a variety of
reaction conditions: dry lithium and sodium salt pyrolyses,
sodium methoxide thermolyses in diglyme and photolyses of
the lithium salt in tetrahydrofuran. The saturated analogues
2-heptanone tosylhydrazone and its 4,4-dimethyl
isomer afforded the...
Background
The National Science Foundation (NSF) has funded multiple research projects dedicated to the development of research and evidence based instructional strategies in an effort to improve the state of science, technology, engineering and math (STEM) education in the US. These efforts have led to an abundance of research based...
A field experiment designed to test the hypothesis that infragravity and lower frequency waves influence the patterns of erosion and deposition on the beach foreshore has been carried out. The data show coherent fluctuations in the foreshore sediment level which can be related to low frequency wave motions. The fluctuations...
Determining the performance characteristics of various ocean wave energy converters (OWEC) has proven to be difficult due to problems replicating a baseline motion profile in the ocean or wave tank to compare these devices. The linear test bed seeks to mechanically simulate the relative linear motion between the active components...
Oceanic plateaus are regions of overthickened oceanic crust and are often thought to form from the interaction of mantle plumes with oceanic lithosphere. These regions can cover vast areas of the ocean basins and represent a highly elevated magmatic flux relative to normal mid-ocean ridge spreading. Oceanic plateaus are considered...
We identify all translation covers among triangular billiards surfaces. Our main tools are the J-invariant of Kenyon and Smillie and a property of triangular billiards surfaces, which we call fingerprint type, that is invariant under balanced translation covers.
A rapid gas liquid chromatographic method was adapted to processed
Dungeness crab for the determination of basic and neutral
volatiles. Methylamine, dimethylamine, and trimethylamine were
measured in processed Dungeness crab for the first time. Generally,
the range for trimethylamine was 42 ppm for frozen crab to 700 ppm
for iced...
Interviewing eighteen older parents (aged 65 and older) with two or more children for this project established support for the emotional experience of intergenerational ambivalence. Seventy-five parent-child relationships were discussed. Two major themes arose over what healthy, independently living parents feel ambivalent about in their relationships with their midlife children....
