Multiple sequence alignment is an essential tool in many areas of biological research, and the accuracy of an alignment can strongly affect the accuracy of a downstream application such as phylogenetic analysis, identification of functional motifs, or polymerase chain reaction primer design. The heads or tails (HoT) method (Landan G, Graur D. 2007. Heads or tails: a simple reliability check for...

We present the results from the analysis of the composite spectrum of five near-IR luminous (K < 20) galaxies at z ∼ 2. Several of the strongest absorption lines are present in the merging galaxy NGC 6090 UV spectrum and are not present in the spectra of Lyman Break Galaxies at z ∼ 3. They were identified as SiIII 1296, CIII 1428, SiII 1485, and Fe ∼1380 Å which are photospheric lines typical o...

In this paper, we produced hemicellulosic hydrolysate from corncob by tetrabutylammonium hydroxide (TBAH) extraction and dilute acid hydrolysis combined, further evaluating the feasibility of the resultant corncob hemicellulosic hydrolysate used in xylitol production by Candida tropicalis. Optimized conditions for corncob hemicellulose extraction by TBAH was obtained via response surface method...

Ethylene phytic acid and unsaturated itaconic could be copolymerized in-situ cross-linked on the cotton fabrics to enhance flame-retardant crease-proofing properties. Natural was modified with glycidyl meth-acrylate characterized by IR, 1H NMR, TG. The IR indicated that new characteristic absorption peaks appear near 1720 c/m, 1470 1380 1002 c/m for molar ratios acid: methacrylate of 1:3 or 1:6...

During the steelmaking process, a great amount of slag is generated as by-product. Vanadium-bearing slags are classified hazardous and require special handling storage due to toxicity vanadium pentoxides. At same time, such valuable sources for recovery vanadium. The present work reviews investigations on from CaO-SiO2-FeO-V2O5 thin film under neutral oxidizing conditions in temperature range 1...
