Structural Analyses of Murine Histocompatibility Antigens
<p>The major histocompatibility antigens are the predominant cell surface molecules recognized by the immune system in the rejection of grafts between individuals of the same species. The genes coding for the histocompatibility antigens are extremely polymorphic; the products of different alleles …

Structural analyses of the ribosome by hybrid approach
… MDFF in two regards, first by incorporating structural symmetry information into the fitting protocol and second by the use of a so-called implicit solvent model. In pursuit of the needed methodological development we participated in the Cryo-EM Modeling Challenge 2010, competing with the …

The Heme -Copper Oxidoreductase Superfamily: Genomics and Structural Analyses
… qNOR, sNOR, eNOR and gNOR) based on enzymatic, structural, genomic, and phylogenetic information. Molecular modeling was then used to characterize the structural properties of the individual families. We predict that the C-type oxygen reductases contain a histidine-tyrosine crosslinked cofactor …

Functional and structural analyses of an olfactory receptor from Drosophila melanogaster
In insects, olfaction is mediated by a large family of integral membrane proteins, called olfactory receptors (ORs), that mediate the transduction of odorant binding into a neuronal signal. A functional assay for insect ORs was developed utilising calcium imaging in Sf9 cells. The Drosophila …

STRUCTURAL ANALYSES OF TRANSCRIPTION FACTOR/DNA COMPLEXES: NFI-X AND NF-Y
… is transferred to biological functions. TF structural analysis is the key to understanding their DNA-binding mode and for the design of specific inhibitors. In this context, the present PhD project focuses on two TFs: (1) NFI-X, a TF with unknown structure that binds to the palindromic motif …

Structural Analyses of Wind Turbine Tower for 3 kW Horizontal Axis Wind Turbine
<p>Structure analyses of a steel tower for Cal Poly's 3 kW small wind turbine is presented. First, some general design aspects of the wind turbine tower are discussed: types, heights, and some other factors that can be considered for the design of wind turbine tower. Then, Cal Poly's wind turbine …

Structural Analysis of Bacillus subtilis Spore Peptidoglycan During Sporulation
… in wild type and many mutant strains. These analyses showed little correlation between the degree of spore PG cross-linking and core dehydration. However, these studies only examined the structure of PG from dormant spores and did not allow for the structural analysis of spore PG during …

High-resolution microwave spectroscopy of several weakly bound complexes.
… The weakly-bound complexes included the two structural isomers of N₂O-HF, the planar bent asymmetric N₂O-HCN complex, the planar bent asymmetric N₂O-HCl complex, and the "stacked" H₂S-SO₂, and H₂S-CO₂ complexes. In all of the cases with the exclusion of the CpNiNO molecule, additional …

A Unified Overlapping Finite Element Formulation
… but also in three-dimensional linear structural analyses. Particularly, the thesis includes the first study on the modal and mode superposition solutions using overlapping finite elements. Illustrative example solutions show that the new discretizations are very promising in reducing …

The crystal and molecular structures of some bioinorganic compounds
In this thesis are presented the results of X-ray structural studies of seven metal-containing crystalline compounds. In some cases, the ligands associated with the metals are themselves biologically active; in other cases, the compound as an entity, rather than any constituent, is of direct or …

Structural insights into conformationally-gated reactions catalyzed by thiamine pyrophosphate-dependent enzymes
… two central metabolites. This thesis presents structural analyses of three TPP-dependent enzymes. Most interestingly, each mechanism of three proteins studied contains a gated step that is drastically accelerated by 3-5 orders of magnitudes through conformational changes. 1-deoxy-D-xylulose …

Formulações semi-empíricas para o colapso hidrostático bi-simétrico de dutos flexíveis
… loads such as the hydrostatic pressure. The structural analyses of those pipes performed by a tridimensional solid model based on the Finite Element Method (FEM) demands a big computational effort due, to among others reasons, the complexity of it cross section. In this work it is developed …

Design of test bench apparatus and preliminary weight reduction strategy for an active knee prosthesis
This thesis presents the design and structural analyses of an experimental test bench for the characterization of an active biomimetic knee prosthesis currently being developed by the Biomechatronics research group at MIT Media Laboratory. Finite element analysis (FEA) is conducted to determine the …

THE TECTONIC EVOLUTION OF THE HATAY OPHIOLITE OF SOUTHEAST TURKEY
A combination of palaeomagnetic and structural analyses have been used to constrain rotations in the Hatay (Kizildag) ophiolite of southeast Turkey in the eastern Mediterranean region and to produce a tectonic model for its evolution. The ophiolite comprises part of a prominent chain of southern …

Structural and Molecular Mechanisms of Centrosome Assembly and Strength
… by PLK-1. Thus, phosphorylation induces a structural opening of SPD-5 that primes it for assembly. Multimerization of SPD-5 is driven by interactions between multiple dispersed coiled-coil domains. Structural analyses of a phosphorylated region (PReM) in SPD-5 revealed a helical hairpin …

Broken-formations of the Pulaski thrust sheet near Pulaski, Virginia
… broken-formations are distinguished from rocks structurally higher on the sheet and from rocks of the underlying Saltville sheet by (1) a sharp increase in the variability of fold and fault styles, (2) greater ranges in fold plunges and dips of axial surfaces, (3) a low degree of preferred …
