An extensive search of published research and review articles indicates that enhancing the sensitivity and resolution of capillary electrophoresis (CE) is a very active area of interest. This review focuses on developments and applications in this field over several years, especially from 2009-present. It first reviews developments in the fields of online sample preconcentration and highly sens...

We present a detailed analysis of the loss performance in an optical buffer having access to a single outgoing channel. Such a system consisting of a number of fiber delay lines differs significantly from a conventional electronic buffer, in that only a discrete set of delays can be realized for contention resolution. This leads to an underutilization of the channel capacity, which reduces over...

Polylactic acid (PLA) fiber, also known as corn fiber, is made of corn and other grains through fermentation, polymerization and spinning. Thus it is biodegradable and environmentally friendly. Three kinds of buffer solutions with PH values of 4, 7.2 and 11 were made for the investigation of the degradation properties of PLA. The experimental results showed that the degradation of polylactic ac...

Diafiltration is term used reflecting tangential flow filtration (TFF) method of “washing” or removing a permeable molecule (impurities, salts, solvents, small proteins, etc) from a solution in an accelerated method when compared to dialysis tubing. By selecting the appropriate membrane(s), it can also be used to exchange buffers, narrow particle size distributions, modify salt concentrations o...

introduction: to examine the long-term effects of normal saline and a synthetic tissue fluid (phosphate buffered saline, pbs) on mineral trioxide aggregate (mta). materials and methods: root-ends of twelve extracted human teeth were resected; root-end cavities were prepared and filled with mta. samples were randomly divided into two groups of six each. teeth in group i were placed in normal sal...

The technology of flash memory SSDs (solid state drives) which are increasingly adopted in a wide spectrum of storage systems has the potential of changing the database architecture and principles. With the high random access speed and high IOPS of the SSD, this paper describes a secondary buffer pool & readahead solution based on OLTP for MySQL InnoDB which can reduce I/O requests & latency an...

The studies were made using cyclic voltammetry on a glassy carbon electrode in aqueous solution containing phosphate buffer solution as supporting electrolyte. The purpose of the investigation was to carry out a quantitative detailed study of the electrochemical oxidation of catechol in the presence of 4, 4-bipyridine in aqueous solution. The electrooxidation of catechol produces a very reactiv...

This paper introduces a linear programming (LP) technique that performs ratedistortion based optimization for constrained video coding. Given the assumption of piecewise linear and convex rate-distortion functions, LP is used to generate optimal solutions for the minmax problem under VBR buffer constraints. The LP solution for this problem avoids an explicit search for the minimum distortion va...

For all measurements (UV-Vis and electrochemistry), the unmodified SiNPs were used as received and diluted to the desired concentration with ultrapure water from Millipore featuring a resistivity of not less than 18.2 MΩ.cm. The following procedure was used for modifying the SiNP with catalase: 79.5 L of SiNPs were added to 119.7 L of water. Next, 20 L of bovine catalase from stock solution ...
