The purpose was to gain information about the determinants of student behavior with respect to laboratory (lab) and non-laboratory (non-lab) science learning activities. Fishbein and Ajzen's (1975) theory of reasoned action was used to investigate students' salient beliefs, correlations between determinants of intention, and the relative weights of determinants of...
Radish anthocyanin extract has potential as a natural colorant because of
its pigment stability and attractive red hue. Presence of undesirable aroma
compounds could limit its applications in foods. The pungent principle of
radish, 4-methylthio-3-butenyl isothiocyanate (MTBI), is produced
enzymatically upon cell injury from its glucosinolate precursor, 4-methylthio-3-butenyl glucosinolate (MTBG),...
Despite many investigations genotype by environment interaction remains
one of the least understood factors in plant improvement. Understanding genotypic
differences responsible for such interactions could assist in making more informed
breeding decisions. The components of yield being less complex than grain yield
per se may be useful for selection to...
Cataract is a leading cause of blindness throughout the world, yet the fundamental biochemical causes are unknown. A rodent model of the biochemical processes is selenite cataract. This cataract shows some of the features of human cataracts such as increased lens calcium, proteolysis of proteins, and insolubilization leading to lens...
Recombinant human calpain-5 was expressed in insect cells using a baculovirus system. The expressed calpain-5 was purified by both traditional chromatography and by affinity-column chromatography. Both methods yielded active protease. Calpain-5 displayed very limited hydrophobicity. This indicated that calpain-5 is not a membrane binding protein. Calpain-5 had pI of 8.3....
Jointed goatgrass (Aegilops cylindrica Host; 2n=4x=28; CCDD) is an
agriculturally important species both as a weed and as a genetic resource for
wheat (Triticum aestivum L.; 2n=6x=42; AABBDD) improvement. In order to
better understand the evolution of this species, the diversity of Ae. cylindrica
was evaluated along with its progenitors,...
Pacific whiting (Merluccius productus) is the most abundant
groundfish species off the California, Oregon and Washington Coasts.
The fish are mainly used as a raw material for the production of surimi.
However, it is not economically wise to depend only on one product.
There is a need to diversify the...
Physical, chemical and sensory attributes were
examined on canned green beans (Oregon 1604) of sieve sizes
3 & 4 and 5 & 6 after one and three months of storage at
room temperature (RT). The green beans subjected to
different pre-blanch conditions in water (T1t1: 160°F - 30
min.; T1t2:...
Static ultra-high pressure (200, 270, and 340 MPa) and sinusoidal and
step-pressure (0-270 MPa) pulses were compared by determining their effects on
bacteria and yeast survival counts. Samples were commercial pineapple chunks
used as is and fresh cut pineapple and pineapple juice inoculated with
Saccharomyces cerevisiae 2407-1a. Surviving bacteria and...
