Magnetic switching behavior for CoCrPt–SiO2 single layer media with oxygen contents (OCs) from 4% to 10% and recording layer thickness (tmag) from 2to27nm is investigated. Significant incoherent switching, caused by domain wall motion, and large ac

Recently a great deal of attention has been focused on giant magnetoresistance (GMR), especially in the coupled multilayer magnetic films. In this report, we show that GMR also exists in nanocomposite films. We have systematically studied the magneto

Summary Sulphur dioxide fumigation (0.34 ppm for 96 hand 0.51 ppm for 72 h) of young jack pine (Pinus banksiana Lamb.) seedlings produced needle tip burning and caused a reduction in their organic acid content. Quinic acid, the major component, decli

An ATPase preparation from pea cotyledon mitochondria was purified by protamine sulfate, ammonium sulfate precipitations, and preparative gel electrophoresis. The ATPase activity was dependent upon Mg2+ and stimulated by Na+ + K+. The optimum pH of t

Incorporation of [U-14C]leucine in jack pine (Pinus banksiana Lamb.) occurred mainly in the chloroplast and soluble cytoplasmic fractions. In the chloroplasts a major portion of the label was associated with the membrane-bound proteins. Fumigation of

Pine needle tissues were shown to incorporate acetate [1- 14 C] into phospho-, galacto- and neutral lipids. The major incorporation of the label among these lipids was always in the phosphatidyl choline (PC) fraction. The amount of label among the ot

Summary Peroxidase (EC 1.11.1.7) activity in jack pine (Pinus banksiana) and white birch (Betula papyri fera) seedlings increased greatly during aging of the foliar tissues. Fumigation of seedlings with SO, caused a marked increase in enzyme activity
