Every year lots of black tea (Camellia sinensis (L.) Kuntze) residue will produce in the factories. These residue are unusable whereas the bio active compounds can be extracted and used in the drag and food industries. Due to mentioned problems, this project was conducted years 2011 - 2012 with the aim to make a study on consecutive isolation of all bio active compounds from tea residu...

In this paper we first show that standard BP algorithm cannot yeild to a uniform information distribution over the neural network architecture. A measure of sensitivity is defined to evaluate fault tolerance of neural network and then we show that the sensitivity of a link is closely related to the amount of information passes through it. Based on this assumption, we prove that the distribu...

Purified BLRV RNA was converted to cDNA and cloned into pT7T3 19U phagemid. The nucleotide sequence of a putative bean leafroll luteovirus coat protein gene was determined from the clones pBL9, pBL29 and pBL32 by the chain termination method (1). Sequence analysis reveals a 588 bp open reading frame and an internal 426 bp ORF (Fig. 1). The large ORF is equivalent to a protein of Mr 21.98 kDa, t...

Cloned DNA copies of rotavirus genomic segment 6 from simian 11 (subgroup 1) and human strain Wa (subgroup 2) rotaviruses have been used to determine the nucleotide sequences of the gene that determines viral subgroup specificity. Both genomic segments are 1,356 nucleotides in length and possess 5'- and 3'-terminal untranslated regions of 23 and 142 nucleotides, respectively. The inferred amino...

MOTIVATION Partially and wholly unstructured proteins have now been identified in all kingdoms of life--more commonly in eukaryotic organisms. This intrinsic disorder is related to certain critical functions. Apart from their fundamental interest, unstructured regions in proteins may prevent crystallization. Therefore, the prediction of disordered regions is an important aspect for the understa...

We reported previously that 933W repressor apparently does not cooperatively bind to adjacent sites on DNA and that the relative affinities of 933W repressor for its operators differ significantly from that of any other lambdoid bacteriophage. These findings indicate that the operational details of the lysis-lysogeny switch of bacteriophage 933W are unique among lambdoid bacteriophages. Since t...

‎In a real Hilbert space‎, ‎an iterative scheme is considered to‎ ‎obtain strong convergence which is an essential tool to find a‎ ‎common fixed point for a countable family of nonexpansive mappings‎ ‎and the solution of a variational inequality problem governed by a‎ ‎monotone mapping‎. ‎In this paper‎, ‎we give a procedure which results‎ ‎in developing Shehu's result to solve equilibrium prob...

The amino acid sequence of the cyanogen bromide fragment 5 of streptococcal proteinase has been determined. This fragment comprises residues 130 to 253 of the proteinase chain. Six tryptic peptides were isolated from maleylated cyanogen bromide fragment 5, and their alignment was obtained by the overlap of chymotryptic peptides. Sequence analysis of tryptic, chymotryptic, and thermolysin peptid...
