In Ihis paper finite elemenl approximations of a one-dimensional nonlinear boundary-value problem in finite elasticity are considered. Under reasonable conditions on the form of the constitutive equations, it is shown that optimal rates of convergence can be obtained in W~.A criterion for the monolonicity of the stress operator is estahlished. In addition, L,,-estimates are also derived. A nume...

The flocculation tests currently used for the serodiagnosis of syphilis involve the use of an aqueous emulsion of cholesterol, beef heart lecithin, and cardiolipin which undergoes aggregation when treated with Wassermann antibody (1). The r81e of cholesterol in ihis reaction has been depicted as providing a particulate surface which enhances the visibility of the aggregates formed by the antige...

A periodic, hard-lheaded assessment of technology has become a routine and plrofitable exercise for most of the large industrial enterprises of the nation. Otur methiods for securing energy, for example, whethier from fossil fuels or atoms or straighlt from the stLin, are subjected to regular review by panels of experts, in and otut of government, in order to make forecasts for the future and a...

BACKGROUND The presence of anti-parvovirus B19 (B19V) IgM against viral capsid proteins (VP1 and VP2) has long been used to detect recent infection. The utility of antibodies directed against B19V NS1 protein has received less attention as a serological indicator of recent infection, although anti-B19V NS1 IgG has been associated with persistent infection. OBJECTIVES To elucidate the role of ...

We present a kinematic analysis program for spatial higher pairs whose parts rotate around or translate along fixed spalial axes. The part geometry is specified in a parametric boundary representation consisting of planar, cylindrical. and spherical patches bounded by line segments and circular arcs. The program consis[S of two pans: contact curve computation and configuration space computation...

36 systemic lupus erythematosus patients with native DNA binding activity (nDNA-BA) in the serum and subepidermal immunoglobulin deposits were studied to determine the relationship of the immunoglobulin (Ig) class distribution of serum nDNA-BA to the clinical characteristics of their disease and to the Ig class present at the dermal-epidermal junction (DEJ). The patients with predominantly (86-...

How health is defined and assessed is a priority concern for Indigenous peoples due to considerable health risks faced from environmental impacts to homelands, and because what is "at risk" is often determined without their input or approval. Many health assessments by government agencies, industry, and researchers from outside the communities fail to include Indigenous definitions of health an...

GEORGE VAUGHAN, aet. 36, whose occupation is that of an extra-tide waiter at the Custom House, in the month of July last, while making a sudden exertion with Ihis right arm, felt (as he expressed it) something snap below the collar bone, attended with a slight degree of pain. In a day or two afterwards, he perceived a small tumor on the fore part of the chest, about an inch and a half below the...

BACKGROUND Despite the decline in childhood caries prevalence, seen particularly in 1980s, in recent years there have been reports that the declining trend has stopped or even reversed in some countries. The aim of the study was to analyse data from previous epidemiological studies on early childhood caries in the Czech Republic, conduct a secondary analysis of trend in dental caries prevalence...
