7—THE PROGRESSIVE DETERIORATION OF TEXTILE MATERIALS PART I: CHARACTERISTICS OF DEGRADATION

K. Slater1986-03-01Journal of the Textile Institute

Textile materials deteriorate, during their useful life, by being subjected to the effects of many degradative mechanisms. Sunlight, weathering, laundering or dry-cleaning treatments, abrasion, perspiration, and other such unavoidable sources of fibre damage all exert their toll on physical or chemical properties to c…

Optical monitoring of nonquarterwave stacks

C. J. van der Laan1986-03-01Applied Optics

The planning of an optical monitoring process for nonquarterwave stacks, using standard equipment for turning value monitoring, is a rather complicated procedure. It is shown that by using a computer program together with some simple rules the planning becomes a more straightforward task. Detailed examples are present…

A simple method to heparinize biological materials

Yasuharu Noishiki、Teruo Miyata1986-03-01Journal of Biomedical Materials Research

A new method was developed inducing antithrombogenicity to biologic materials. A basic protein, protamine, was used to increase heparin binding to collagenous materials. Protamine sulfate solution was poured into a collagen-rich material (porcine ureter). The protamine adsorbed to the collagen was then cross-linked to…

Localized Corrosion of Iron in Alkaline Sulfide Solutions: Iron Sulfide Formation and the Breakdown of Passivity

José Vera、S. Kapusta、Norman Hackerman1986-03-01Journal of The Electrochemical Society

The breakdown of passivity of iron in alkaline sulfide solution is a two‐step process. The first step involves the nucleation of mackinawite patches at faults in the oxide film and their subsequent growth by dissolution of the oxide. The second step is associated with the growth of pits under these patches. At higher…

Silver-enhanced colloidal gold as a cell surface marker for photoelectron microscopy.

G. Bruce Birrell、D.L. Habliston、Karen K. Hedberg 等 4 位作者1986-03-01Journal of Histochemistry & Cytochemistry

Colloidal gold labeling in conjunction with silver enhancement was investigated as a labeling technique for photoelectron microscopy (PEM). PEM uses UV-stimulated electron emission to image uncoated cell surfaces, and markers for cell surfaces need to be sufficiently photoemissive to be clearly visible against this ba…

Small Signals, Large Signals, and Saturation in Generator Modeling

S.H. Minnich1986-03-01IEEE Transactions on Energy Conversion

Test and analytic results from recent EPRI-sponsored programs are organized to explain insights into generator modeling. It is shown how small-signal tests and analysis are related to the nonlinear incremental properties of rotor iron. Changes in rotor circuit topology caused by rotation are identified. The large-sign…

Effect of Soil Organic Matter Accumulation on Potassium and Ammonium Quantity‐intensity Relationships

V. P. Evangelou、A. D. Karathanasis、R. L. Blevins1986-03-01Soil Science Society of America Journal

Abstract Quantity‐intensity ( Q/I ) relationships for potassium (K + ) and ammonium (NH 4 + ) in a Maury silt loam soil (fine‐silty, mixed, mesic, Typic Paleudalfs) under long‐term conventional and no‐tillage management were investigated to determine changes in solute‐soil interactions brought about by differential or…

Halide formation and etching of Cu thin films with Cl2 and Br2

Seongju Park、T. N. Rhodin、L. Rathbun1986-03-01Journal of Vacuum Science & Technology A Vacuum Surfaces and Films

Etching mechanisms of Cu thin films under the exposure of an argon ion beam and halogen molecules (Cl2, Br2) were examined in a UHV system using a quartz crystal oscillator and x-ray photoelectron spectrometer. Chlorine exposure at room temperature produced a very stable chlorine overlayer on the Cu surface. The passi…

Adsorption of Bacterial Surface Polymers to Attachment Substrata

James H. Pringle、Madilyn Fletcher1986-03-01Microbiology

SUMMARY: Extracellular polysaccharide (EP) and lipopolysaccharide (LPS) were isolated from three strains of Pseudomonas fluorescens (a wild-type and two mutants) and the adsorption isotherms (relationship between amount of polymer adsorbed and bulk liquid concentration of polymer in solution) of these polymers to hydr…

van der Waals induced dipoles

Bruno Linder、Robert A. Kromhout1986-03-01The Journal of Chemical Physics

Expressions are derived for calculating the induced dipole moment of an arbitrary molecule A interacting with an arbitrary system B through first- and second-order Coulomb interaction. The theory is formulated in terms of linear and quadratic charge-density susceptibilities and takes account of charge penetration but…

Metastable water at subzero temperatures

Felix Franks1986-03-01Journal of Microscopy

SUMMARY The origins of physical and chemical metastability in aqueous systems are discussed with particular reference to supersaturated solutions, i.e. those where eutectic phase separation does not normally occur. Such solutions are characterized by high viscosities, and under conditions of rapid cooling to the glass…

Amino acid sequence of the phosphorylation site of yeast (Saccharomyces cerevisiae) fructose-1,6-bisphosphatase.

Judith Rittenhouse、Peter B. Harrsch、J N Kim 等 4 位作者1986-03-01Journal of Biological Chemistry

Fructose-1,6-bisphosphatase from the yeast Saccharomyces cerevisiae has properties similar to other gluconeogenic fructose-1,6-bisphosphatases, but an unusual characteristic of the yeast enzyme is that it can be phosphorylated in vitro by cAMP-dependent protein kinase. Phosphorylation also occurs in vivo, presumably a…

Effect of Nucleation on Transformation Toughening

John C. Lambropoulos1986-03-01Journal of the American Ceramic Society

A simple model is presented to account for the effect of martensitic nucleation in ZrO 2 particles on theoretical predictions of toughness enhancement during transformation toughening. The model allows for shear and volumetric strain contributions during nucleation, whereas only volumetric strain contributes to toughn…
