To investigate the factors regulating concentration of particulate iodine (PI) in seawater, it was measured two Pacific coastal areas adjacent to Japan (offshore Aomori and offshore Fukushima) seasons (May October) along with parameters such as organic carbon (POC) nitrogen (PON), dissolved (DI), phytoplankton pigments. The observed PI concentrations ranged from 0.0068 2.2 nmol L−1, uncertain s...

As a sequel to a recent work we consider the generalized stress concentration factor, a purely geometric property of a body that for the various loadings, indicates the ratio between the maximum of the optimal stress and maximum of the loading fields. The optimal stress concentration factor pertains to a stress field that satisfies the principle of virtual work and for which the stress concentr...

The concentration method of edge detection was developed to compute the locations and values of jump discontinuities in a piecewise-analytic function from its first few Fourier series coefficients. The accuracy and characteristic features of the resulting jump approximation depend on Fourier space “filter” factors known as concentration factors. In this paper, we provide a flexible, iterative f...

To clarify the significance of increased blood sialic acid in atherosclerotic cardiovascular disease, we investigated the relationship between serum sialic acid level and atherosclerotic risk factors such as serum uric acid, fasting blood glucose, systolic and diastolic blood pressure, atherogenic index, and white blood cell count. By simple regression analysis, the serum sialic acid level was ...

Hollow sections are most suitable for welded connections between members. The welding procedure is fairly straightforward in RHS, because they do not require profiling which is necessary for circular hollow sections. Although many multiplanar and uniplanar joints in structures are present, limited evidence is available for the fatigue behaviour of joints made of rectangular hollow sections. Thi...

Darunavir is an efficacious drug; however, pharmacokinetic variability has been reported. The objective of this study was to find predisposing factors for low darunavir plasma concentrations in patients starting the once- or twice-daily dosage. Darunavir plasma concentrations from January 2010 till December 2014 of human immunodeficiency virus-infected individuals treated in the outpatient clin...

Background. Patients afflicted with Alzheimer's disease (AD) exhibit a decrease in the cerebrospinal fluid (CSF) concentration of the 42 amino acid form of beta-amyloid (Abeta(42)). However, a high discrepancy between different centers in measured Abeta(42) levels reduces the utility of this biomarker as a diagnostic tool and in monitoring the effect of disease modifying drugs. Preanalytical an...

The concentration of protein in the cerebrospinal fluid (CSF) is about 0.5 per cent that of plasma. This difference in concentration is generally considered (1) to be dependent upon the blood-CSF barrier. The normal concentration gradient of protein from a low level in the ventricles, 6 to 15 mg. per cent, to an intermediate level in the cisterna magna, 15 to 25 mg. per cent, to the highest lev...
