Volatile compounds of eight pear varieties were isolated and identified by
GC/MS. A total of 112 components were identified from headspace of intact fruits,
including 47 compounds reported for the first time in pear. The volatile profiles of
these pear varieties were characterized by esters, alcohols, hydrocarbons, aldehydes
and ketones....
Powder injection molding (PIM) is a net fabrication technique that combines the
complex shape-forming ability of plastic injection molding, the precision of die-casting,
and the material selection flexibility of powder metallurgy. For this
study, the design issues related to PIM for fabrication of thin-walled high-aspect
ratio geometries were investigated. These...
This research is aimed at obtaining a better understanding of the impact of the use of collaborative and simulation sessions for learning lean principles and methods. Study participants were enrolled in a Lean Manufacturing System Engineering (IE436/536) course at Oregon State University or at three other business and engineering universities...
Adult onset progressive alopecia and leukotrichia developed in 2 registered black Angus cows, aged 6 and 7
years. Histopathologic findings in skin were prominent melanin clumping and degeneration of matrix cells with formation
of giant multinucleate cells within hair bulbs, accompanied by peribulbar melanin incontinence and fibrosis and dystrophic
hair...
Water in 70 percent of the cities in the United States is hard enough that softening is either required or recommended. It is estimated that approximately 30 percent of all homes in the United States use water softeners. Water softeners, the cation exchange types suited for residential use, exchange sodium...
This research has focussed upon both the in vitro and in vivo characterization
of the recycling pathway leading from 5'-deoxy-5'-methylthioadenosine
to methionine in fruit. In addition to contributing towards polyamine
biosynthesis and other important cellular functions, in plant tissues
these events also serve to generate the hormone ethylene. A broad...
Ovipositional behavior of the codling moth, Laspeyresia pomonella (L.), on several varieties of apples and pears grown in the Pacific Northwest was investigated during the spring/summer of 1979. Field studies showed that early in the season more eggs were laid on the Bosc variety than on several other apple and...
