By an Arnold cell technique, the diffusion coefficients of propanol
and methanol in mixtures of air and argon system have been determined.
The carbon tetrachloride-air system was also studied to verify
the reproducibility of the experimental method.
The diffusion coefficients were compared with experimental
values when available and with values...
Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...
Hydrocarbon solvents are widely used in the production of paints, adhesives, dyes, polymers, plastics, textiles, printing inks, agricultural products and pharmaceuticals. While the neuropathic potential of aliphatic solvents was shown in the 1970s, little is known about the neuropathic potential of aromatic solvents. The present study examines such solvents, 1,2-diethylbenzene...
Objective:
To evaluate the effect of Nelumbo Nucifera leaf water extract (NNLE) on insulinoma (RIN) cells induced by interleukin-1ß (IL-1ß) and interfer-on-g (IFN-γ), and injured pancreatic ß-cells induced by Streptozotocin (STZ) in rats.
Methods:
The anti-oxidative effects of NNLE were assessed using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and nitric oxide (NO) scavenging assays....
Escherichia coli double-strand uracil-DNA glycosylase (Dug) was purified to apparent homogeneity from bacteria that were defective in uracil-DNA glycosylase (Ung). After cloning the dug gene, recombinant Dug was overexpressed, purified, and characterized with respect to activity, substrate specificity, product DNA binding, and mechanism of action. Purified Dug excised both uracil...
The contributions of Korean immigrant-owned fashion companies (KIOFCs) are increasing in the U.S. fashion industry. This study explored more deeply how KIOFCs can obtain competitiveness in the fiercely competitive fashion market. Specifically, this study 1) described the prominent characteristics of KIOFCs in the Los Angeles area, 2) investigated the multidimensional...
The demand for portable electronic systems and the continued
down-scaling of device dimensions resulted in rapid improvement in
the performance of integrated systems. Several low-voltage design
techniques have been proposed to operate analog circuits with sub-1V
supply. However, these techniques require higher power consumption
to achieve large dynamic range while...
The photodebromination of selected bromoarenes has been studied at 300 nm
to determine the the possible mechanistic pathways leading to product.
Irradiation of 4-bromobiphenyl (BpBr) at this wavelength leads to the product
biphenyl. The quantum yield of intersystem crossing (0.98) and quenching
studies with cis-1 ,3-pentadiene suggest that the reaction...
This paper is a study of the design of an integrated MOS addressing
circuit by using the modified two-phase dynamic shift register. This modified circuit is compared to the conventional two-phase
dynamic SR and discussed briefly. The resulting circuit shows
several advantages to improve the essential conditions of integrated
circuit...
The effect of increased egg consumption on plasma
cholesterol levels and its distribution among lipoproteins and
Apolipoprotein A-I/A-II ratios of high density lipoprotein
subfractions in individuals who did and did not demonstrate response
in plasma cholesterol levels was studied in 20 healthy middle-aged
men (30-55 years of age) for three...
