The dynamics of circulant and near-circulant systems
Acta Mechanica, 1978Point mass systems in which the interaction matrix is a symmetric circulant occur in a wide variety of physical situations. In many cases also the interaction matrix, while not being a circulant, may differ only slightly from one. The dynamics of both exact and near-circulant systems are analysed in the present paper.

Hydromechanical simulation of systemic circulation
Medical & Biological Engineering, 1974A hydromechanical model is developed for the simulation of the arterial systemic circulation. The geometry and elastic properties of arteries, the pulse-rate and stroke volume of the left ventricle, the design of peripheral resistances and the viscosity of the model fluid are approximated to physiological conditions.

Circulating immune complexes in systemic amyloidosis
Clinical Immunology and Immunopathology, 1981Abstract Serum immune complexes were measured in patients with immunocytic amyloidosis (8 patients), reactive amyloidosis (6 patients), and amyloidosis secondary to familial mediterranean fever (11 patients). 125 I-C lq -binding method and 4% PEG precipitation methods were employed for immune complex determinations.

Effect of Dilazep on Coronary and Systemic Circulations
Pharmacology, 2008In order to assess the effects of dilazep on central hemodynamics and regional flows, 0.2 mg/kg of the drug were administered intravenously to 6 open-chest anesthetized dogs. Hemodynamic and flow measurements were performed under control conditions, and approximately 5, 10 and 25 min after treatment.

On the Solution of Circulant Linear Systems
SIAM Journal on Numerical Analysis, 1987The paper presents efficient methods for the solution of linear systems having circulant (banded circulant, block circulant) coefficient matrices. The proposed methods are more efficient than Toeplitz type methods and are based on the fast Fourier transform as well as the circulant factorization of ''banded'' circulant matrices.

Andrea Cesalpino and systemic circulation
Annales Pharmaceutiques Françaises, 2004Although since the publication of the De motu Cordis in 1628 the majority of historians have considered William Harvey the discoverer of the blood circulation, a minority of authors have tried to show that the laurels belong instead to Andrea Cesalpino (c.1520-1603).
