Introduction: The paper addresses the effect of a composite modifying mineral additive based on waste — tailings from Balkhash Mining and Processing Plant microsilica structural characteristics performance heavy concrete. Purpose study: We aimed to select optimal B25 B35 concrete mixes MV-D20 modified binder with in its composition evaluate Methods: In course study, standard methods were used d...

The effective ionic radii of Shannon & Prewitt [Acta Cryst. (1969), B25, 925-945] are revised to include more unusual oxidation states and coordinations. Revisions are based on new structural data, empirical bond strength-bond length relationships, and plots of (1) radii vs volume, (2) radii vs coordination number, and (3) radii vs oxidation state. Factors which affect radii additivity are poly...

In the present work bagasse (B) i.e waste of the sugar industry, was fed to Eisenia fetida with cattle dung (CD) support as feed material at various ratios (waste: CD) of 0:100 (B0), 25:75 (B25), 50:50 (B50), 75:25 (B75) and 100:0 (B100) on dry weight basis. Co-composting with cattle dung helped to improve their acceptability for E. fetida and also improved physico-chemical characteristics. Bes...

Three phenomena—the disparity between the assumed and observed attributes of economic man, the link between nature and artifacts, and the use of computers as a source of knowledge––fascinated Herbert A. Simon. He built a new paradigm for each field—bounded rationality to deal with the disparity, the science of the artificial as its link to nature, and artificial intelligence for creation of kno...

A great deal of work has been directed toward increasing the yield of penicillin in fermentations with Penicillium chrysogenum. The spectacular increase in yield which has been achieved has resulted, in the main, from two approaches. In the first approach, mutant strains of P. chrysogenum produced by spontaneous variation or by the action of mutagenic agents such as nitrogen mustard or ultravio...

We present a completed list of polynomial dominanting maps of C2 with branched value curve isomorphic to the complex line C, up to polynomial automorphisms. AMS Classification : 14 E20, 14 B25. 1. Let f : C −→ C be a polynomial dominanting map, Close(f(C)) = C, and denote by degf the geometric degree of f the number of solutions of the equation f = a for generic points a ∈ C. The branched value...

Human insulin-like growth factors I and II (hIGF-I, hIGF-II) are potent stimulators of cell and growth processes. They display high sequence similarity to both the A and B chains of insulin but contain an additional connecting C-domain, which reflects their secretion without specific packaging or precursor conversion. IGFs also have an extension at the C-terminus known as the D-domain. This pap...

The kinetic properties of the insulin receptor were studied in solution after its purification to homogeneity. Dissociation of 125I-labeled insulin at a 1:50 dilution was not first order; unlabeled insulin at physiological concentrations accelerated the dissociation rate with a maximal effect at approximately 17 nM. At higher concentrations, the unlabeled insulin slowed the dissociation rate. M...

We cross-correlate the optical catalogue of galaxies in the field of the Perseus cluster (Abell 426) with IRAS PSC sources. The optical catalogue comprises data on 660 galaxies brighter than B25 ≈ 19.5 (Brunzendorf & Meusinger 1999). A sample of 19 IRAS galaxies is found. According to their redshifts, 17 galaxies are likely members of the Perseus cluster, two are background galaxies. The sample...

Insulin is a major target of the autoimmune response associated with destruction of pancreatic beta cells in type 1 diabetes. A peptide that spans the junction of the insulin B chain and the connecting (C) peptide in proinsulin has been reported to stimulate T cells from humans at risk for type 1 diabetes and autoimmune diabetes-prone NOD mice. Here we show that proinsulin B24-C36 peptide binds...
