Erratum After the publication of this article [1] it was noticed that Table 3B was misaligned. In Table 3B in both the PDF and online versions: Mexican Americansthe numbers "135, 236, Ref, 41, 330, Ref" should be shifted to the right (i.e., "135" should read under MetS "Yes" column; "236" under MetS "No" column; "Ref" under "PR" column for MetS ; "41" under CVD risk (>15%) "Yes" column; "330" u...

a column of alumina modified with sodium dodecyl sulfate (sds) and dimethylglyoxime (dmg) was prepared for the preconcentration of trace nickel from water samples for flame atomic absorption spectrometry (faas) determinations. under optimized conditions (ph=7.0; flow rate: 20 mlmin-1) nickel was retained on the column. the nickel collected on the column was eluted with 5 ml of 1 m nitric acid. ...

Let p1, p2,..., pn be a sequence of n pairwise coprime positive integers, and let P = p1p2...pn. Let 0, 1, ...,m − 1 be a sequence of m different colors. Let A be an n ×mP matrix of colors in which row i consists of blocks of pi consecutive entries of the same color, with colors 0 through m − 1 repeated cyclically. The Monochromatic Column problem is to determine the number of columns of A in w...

Now and then, we see discussions or debates about orchestration versus choreography. Often, it’s no more than the standard ‘my technique is better than your’s’, talking but not listening approach. Or, it’s focused on a simplified differentiation between BPEL and WS-CDL aimed at making sense of why we have so many different standards (good question). Here, the typical line is that BPEL is for or...

Detailed examination of the midbrain Edinger-Westphal (EW) nucleus revealed the existence of two distinct nuclei. One population of EW preganglionic (EWpg) neurons was found to control oculomotor functions, and a separate population of EW centrally projecting (EWcp) neurons was found to contain stress- and feeding-related neuropeptides. Although it has been shown that EWcp neurons are highly re...

In this study, liquid-liquid extraction process in a Kuhni extraction column was modeled and simulated. A non-equilibrium dynamic model was developed for modeling liquid-liquid extraction processes based on a rate-based model. The model equations are inclusive of partial and ordinary differential equations which were discretized in column height direction. The population balance model was used ...

background: streptokinase is a potent activator of plasminogen to plasmin, the enzyme that can solubilize the fibrin network in blood clots. streptokinase is currently used in clinical medicine as a thrombolytic agent. it is naturally secreted by β-hemolytic streptococci. methods: to reach an efficient method of purification, an immunoaffinity chromatography method was developed that could puri...

background: cytoadherence of plasmodium falciparum - infected red blood cells to endothelial cells is an important mechanism for parasite survival and a major trigger for diseases pathology. here, we de­scribe a new adhesion assay in which different cell types (cho, cho/cd36 and cho/icam-1) are at­tached to cytodex beads in a mini-column format to measure the relative sizes of various binding s...

to examine how water retention characteristics in a landfill environment change as a result ofsolid waste settlement and to derive the evolution of pore size distribution, a lab scale long column experiment was carried out at two different time periods while keeping all the other characteristics constant. two columns, column 1 and column 2, were used in the study. the log normal distribution mo...
