R. D. Shull National Institute of Standards and Technology, Gaithersburg, MD 20899-0001, USA The paper presents a theoretical analysis of elastic magnetic small-angle neutron scattering (SANS) due to the nonuniform magnetic microstructure in nanocrystalline ferromagnets. The reaction of the magnetization to the magnetocrystalline and magnetoelastic anisotropy fields is derived using the theory ...

BACKGROUND Exposure to combustion-derived fine particulate matter (PM) is associated with increased cardiovascular morbidity and mortality especially in individuals with cardiovascular disease, including hypertension. PM inhalation causes several adverse changes in cardiac function that are reflected in the electrocardiogram (ECG), including altered cardiac rhythm, myocardial ischemia, and redu...

The anodic stripping voltammetry at a carbon paste electrode modified with thiol terminated self-assembled monolayer on mesoporous silica (SH-SAMMS) provides a new sensor for simultaneous detection of lead (Pb2+) and mercury (Hg2+) in aqueous solutions. The overall analysis involved a two-step procedure: an accumulation step at open circuit, followed by medium exchange to a pure electrolyte sol...

40 : 40 : 20, respectively. Factor T was purified by eluting with acetonitrile water 60 : 40. The purified antibiotics precipitated from the elutes after elimination of the acetonitrile under vacuum.GE2270factors were obtained as white powders showing HPLCretention times and molecular weights reported in Table 1. Factor T showed UV spectra with ^MCl 250, 280 (sh), 345 (sh); ^maxN KOH 240 (sh), ...
