Abstract:

We study the Galois module structure of some abelian extensions of an imaginary quadratic field. Our investigation is motivated by a well-known case in cyclotomic theory and work of M.J. Taylor. We consider extensions <i>N/L</i> where <i>N</i> (resp. <i>L</i> ) is the ray class field of conductor <i>lp<SUP>{m+r}</SUP> (resp. {it lp^{r} ) over some imaginary quadratic field ({it l} denotes an odd prime and {it p} belongs to a certain class of prime ideals). We also consider briefly the case where {it p} is composite. The object of study is O_N as a module over its associated order. We describe

Abstract:

Let Г be a metacyclic group of order pq with p and q prime. We shall show that the Г-cohomology and character of a Г-lattice determine its genus. Let N/L be a Galois extension with group Г, then U(_N), the torsion-free units of N, is a Г-lattice and the isomorphism Q o U(_N) = Q o ɅS(_oo) gives its character. In certain cases we can determine its cohomology and thus its genus; in particular, when = h(_N) = 1 and L = Q we show that the genus of U(_N) depends only on the number of non-split, ramified primes in N/L. We shall also investigate U(_N) in the factorizability defect Grothendieck group.

The technique of electron yield-EXAFS has been used to derive information about the different structures of amorphous films, formed anodically on pure aluminium when various electrolyte solutions are used.

The amorphous oxide produced in neutralised sodium oxalate gives an average Al-0 separation of 0.185 nm, while the porous oxides formed in strong aggressive electrolytes, chromic a

We have quantitatively demonstrated that the conductivity enhancement of thiophene–S doped rGO is not only caused by the more effective reduction induced by S doping, but also by the doped S atoms, themselves. Furthermore, we demonstrate that the S doping is more effective in enhancing conduct

The macrocyclic square planar nickel complex, [Ni II CR] 2+ , has been shown to be a useful DNA or RNA structure probe due to its highly site- and conformation specific ability to induce cleavage on exposed guanine residues via the formation of a direct guanine N7-Ni III bond. Since the postulated intermediate [Ni III CR] 3+ is unstable, the detailed mechanism is unknown. In this study, the nature of the interaction of NiCR 2+ and its oxidized products with biomolecules was investigated.

We initially explored whether MBP would have the same effect in the methylotrophic yeast Pichia pastoris , a popular eukaryotic host for heterologous protein expression.

Abstract:

Protein sequences contain the information in order for a protein to fold to a unique compact, three-dimensional native structure. The forces that drive protein structures to form compact folds are largely dominated by burial of hydrophobic amino acids, which results in non-specific packing of amino acid side-chains. The knob-socket model attempts to organize side-chain packing into tetrahedral packing motifs. This tetrahedral motif is characterized with a three residues on the same secondary structure forming the base of the tetrahedron packing with a side-chain from a separate secondary struc

Abstract:

The results presented here are concerned with questions of decomposability of multiplicative semigroups of matrices with nonnegative entries. Chapter 1 covers some preliminary results which become useful in the remainder of the exposition. Chapters 2 and 3 constitute an exposition of some recent known results on special semigroups. Chapter 2 explores conditions for decomposability of semigroups in terms of conditions derived from linear functionals and in Chapter 3, we give a complete proof of an extension of the celebrated Perron-Frobenius Theorem. No originality is claimed for the result

Abstract:

Cumulative effects, often minor individually but collectively significant, are continually being grappled with by researchers, policy makers and practitioners. Despite this the Canadian approach to cumulative effects assessment is thought by many to be ineffective. In this thesis I investigate the literature that surrounds cumulative effects and uncovered three distinct themes that occur chronologically: genesis, project-based approach and integration. During the genesis phase cumulative effects nomenclature, ideas and frameworks was created. The main theme of this era was to asses these effec

The purpose is to study the using electro spinning method and spin coating respectively to prepare different F8T2、PFO、P3HT、PCBM blended fiber structure. We use low molecular weight conductive polymer and we don’t use salt to fabricate electrospinning nanofibers.
