Tipburn is a widespread physiological disorder of cabbage and
lettuce, caused by calcium deficiency. Symptoms of tipburn are
necrosis on margins of outer and inner head leaves in lettuce,
whereas in cabbage it is only on margins of inner leaves. Tipburn
on outer leaves may develop early, but symptoms remain...
For ras gene mutation analysis in the rainbow trout (Oncorhynchus
mykiss) model system, a partial trout ras sequence was identified
using the polymerase chain reaction (PCR). Two synthetic
oligonucleotides based on rat K-ras gene sequence were used as
primers for the PCR procedure. A 90 base pair (bp) sequence,
referred...
The pore size distribution of several battery separators were
determined experimentally by mercury penetration method using the
Aminco-Winslow porosimeter. The performances of the separators under
electrolyte penetration were also studied. The results of electrolyte
penetration revealed that the degree of penetration was affected
by the anions of the entrained salts...
Swiss needle cast (SNC) is a foliage disease of Douglas-fir caused by Nothophaeocryptopus gaeumannii, an Ascomycete fungus (Mycosphaerellaceae) that causes growth reductions in Douglas-fir plantations across the Pacific Northwest. Epidemiology of the fungus is generally well known in plantation trees, but the relationship between disease expression and foliage nutrition and...
An experimental study was made of acoustic switching of
pneumatic turbulence amplifiers. The development of fluidic devices
was generally reviewed, and the operation of the pneumatic turbulence
amplifiers made for testing was described. The characteristics
of the turbulence amplifiers were experimentally determined
and found to be typical for this type...
DNA from the human squamous carcinoma cell line, SK-MES-1, and the
plasmids, pUC EJ6.6 containing H-ras oncogene, pSVc-mycl containing
cellular myc gene, pNRSac containing N-ras oncogene, pBR SV containing
SV40 virus DNA, pSV2-neu containing neu oncogene and pSV2-neo
containing neomycin resistant gene were used to transform Balb serum-free
derived mouse...
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...
The major limiting factor of DRAM access time is the low transconductance of the
MOSFET's which have only limited current drive capability. The bipolar junction
transistor(BJT) has a collector current amplification factor, β, times base current and is
limited mostly by the willingness to supply this base current. This collector...
This thesis examines the influence of Christian missions on Yung Wing (1828-1912) during the nineteenth century, when China was beginning to encounter the West. Yung was the first Chinese graduate student to enter an American institution of higher education (Yale College, 1854). As a Westernized Christian intellectual, he strove to...
An aqueous solution of technical glyphosate [N-(phosphonomethyl)
glycine] was applied in homogeneous sprays of 120, 180 and 300 μm
droplets to seedlings of a bush type green bean (Phaseolus vulgaris
L. 'OSU 1604') at a carrier rate of 20 1/ha. At each droplet size
all combinations of 3 dosage levels...
