The aim of this work is to evaluate the characteristics of activated and non-activated carbon obtained from carbon-enriched coal fly ashes (CECFA) from two different power stations to be used in the low temperature reduction of NO from stack gases. Carbon-rich fractions were obtained by mechanical sieving of fly ashes and by oil agglomeration. Activation of some samples was carried out in steam...

Separation of model mixtures of peptides/proteins carried out in a hydrophilically coated capillary in 10 mmol/l Tris and 75 mmol/l phosphate buffer containing 7.5% (w/w) Pluronic F127 copolymer (apparent pH 2.9) revealed that the separation is predominantly driven by the charge/mass ratio with little or no sieving effect. Using a coated capillary helped to remove current fluctuations that are ...

The increase in the incorporation of amino acids into protein in vitro by preparations obtained from protein-fed rats as compared with preparations obtained from carbohydrate-fed rats has been described previously. After molecular sieving through Sephadex G-25 of cell-free preparations, the difference in incorporating activity between the two types of rats was diminished in systems containing A...

Noncontiguous I/O access is the main access pattern in many scientific applications. Noncontiguity exists both in access to files and in access to target memory regions on the client. This characteristic imposes a requirement of native noncontiguous I/O access support in cluster file systems for high performance. In this paper, we address two main issues on supporting efficient noncontiguous I/...

Sieve is a device for separating wanted elements from unwanted material or characterizing the particle size distribution of sample, typically using woven screen such as mesh net. A lot sieve product that are in market money consuming. Skilled workers also required to operate product. Other than that, it big space install higher maintenance one problems user faces.
