The authors develop a system of differential equations describing the motion of the structural system equipped with DFP bearings. The Runge-Kutta numerical method, specifically the ode15s function in MATLAB, was used to solve these equations. The results of the calculations provide a comparison of the damping efficiency of the structural system with and without the use of DFP bearings, assessing the effectiveness of vibration isolation during an earthquake, with three components X, Y, and vertical considered.

This thesis intends to develop application-level access control models to address several major security issues in enterprise environments. The first goal is to provide simple and efficient authorization specifications to reduce the complexity of security management. The second goal is to provide dynamic access control for Web service applications. The third goal is to provide an access control framework for Semantic Web services. In this thesis, an Authorization-Function-Based Role-based Access Control (FB-RBAC) model is proposed for controlling enterprise systems at the application level.

The broad aim of this research project is to optimize planned and emergency maintenance tasks and timings for tram tracks. Consistent with that broad aim, the following specific objectives are identified: Understand the factors affecting the degradation of tram tracks; develop a degradation prediction model for tracks as a function of the influencing factors; evaluate the time and type of maintenance required for deteriorated rail tracks.

Regulator of G-protein signaling (RGS) proteins were originally identified as negative regulators of G-protein-coupled receptor (GPCR) signaling via their GTPase-accelerating protein (GAP) activity. All RGS proteins contain evolutionarily conserved RGS domain; however, they differ in their size and regulatory domains. RGS1 and RGS10 are smaller than other RGS proteins, and their functions involve various inflammatory responses including autoimmune responses in both the periphery and the central nervous system (CNS). Neuroinflammation is the chronic inflammatory response in the CNS.

Regulator of G protein signaling (RGS) proteins are gatekeepers regulating the cellular responses induced by G protein-coupled receptor (GPCR)-mediated activation of heterotrimeric G proteins. Specifically, RGS proteins determine the magnitude and duration of GPCR signaling by acting as a GTPase-activating protein for Gα subunits, an activity facilitated by their semiconserved RGS domain. The R7 subfamily of RGS proteins is distinguished by two unique domains, DEP/DHEX and GGL, which mediate membrane targeting and stability of these proteins.

In recent years, legislative and market requirements have driven the need to reduce fuel consumption while meeting increasingly stringent exhaust emissions. This trend has dictated increasing complexity in automotive engines and new approaches to engine design. A key research objective for the automotive engineering community has been the potential combination of gasoline-engine specific power with diesel-like engine efficiency in a cost-competitive, production-feasible power train.

Stress-activated protein kinase (SAPK) signaling plays essential roles in eliciting adequate cellular responses to stresses and proinflammatory cytokines. SAPK pathways are composed of three successive protein kinase reactions. The phosphorylation of SAPK signaling components on Ser/Thr or Thr/Tyr residues suggests the involvement of various protein phosphatases in the negative regulation of these systems.

Thyrotropin-releasing hormone receptor (TRHR) has already been cloned in mammals where thyrotropin-releas-inghormone (TRH) isknowntoactasapowerful stimulator of thyroid-stimulating hormone (TSH) secretion. The TRH receptor of amphibians has not yet been characterized, although TRH is specifically important in the adaptation of skin color to environmental changes via the secretion of a-melanocyte-stimulating hormone (a-MSH).

Short-chaindehydrogenases/reductases (SDRs) are enzymes of great functional diversity. Even at sequence identities of typically only 15–30%, specific sequence motifs are detect-able, reflecting common folding patterns. We have devel-oped a functional assignment scheme based on these motifs and we find five families. Two of these families were known previously and are called
classical and
extended families, but they are now distinguished at a further level based on coenzyme specificities.

An RBCC (RING finger, B-box, and coiled-coil) protein was identified that belongs to the superfamilyof zinc-binding proteins and is specifically expressed in the gill of eel, Anguilla japonica. Euryhaline fishes such as eels canmigrate between freshwater and seawater, which is considered to be accomplished by efficient remodeling of the architecture and function of the gill, a major osmoregulatory organ.

Understanding peroxidase function in plants is complicated by the lackof substrate specificity, the highnumber of genes, their diversity in structure and our limited knowledge of peroxidase gene transcription and translation. In the present study we sequenced expressed sequence tags (ESTs) enco-ding novel heme-containing class III peroxidases from Arabidopsis thalianaand annotated 73 full-length genes identified in the genome.

Tumor necrosis factor (TNF)-related apoptosis inducing ligand (TRAIL) has been known to induce tumor-specific apoptosis and to share the structural and functional char-acteristics with the proteins of TNF family. Recently, the crystal structure of humanTRAIL showed that TRAIL is a homotrimeric protein whose subunits contain mainly b-sheets. We characterized the structural changes of recombinant human TRAIL induced byacidification and the biological implication of the structural characteristics at acidic pH in the interaction with the lipid bilayer. ...

14-3-3 proteins play an important role in a multitude of signalling pathways. The interactions between 14-3-3 and other signalling proteins, such as Raf and KSR (kinase suppressor of Ras), occur in a phospho-specific manner. Recently, a phosphorylation-independent interaction has been reported to occur between 14-3-3 and several proteins, for example 5-phosphatase, p75NTR-associated cell death executor (NADE) and the bacterial toxin Exoenzyme S (ExoS), an ADP-ribosyltransferase from Pseudomonas aeruginosa. ...

The different roles of ubiquinone-10 (UQ10) at the primary and secondary quinone (QAand QB) binding sites ofRho-dobacter sphaeroidesR26 reaction centres are governed by the protein microenvironment. The 4C¼O carbonyl group of QAis unusually strongly hydrogen-bonded, in contrast to QB. This asymmetric binding seems to determine their dif-ferent functions. The asymmetric hydrogen-bonding at QA can be caused intrinsically by distortion of the methoxy groups or extrinsically by binding to specific amino-acid side groups. ...

CYP73 enzymes are highly conserved cytochromes P450 in plant species that catalyse the regiospecific 4-hydroxylation ofcinnamicacid to formprecursorsofligninandmanyother phenolic compounds. A CYP73A1 homology model based on P450 experimentally solved structures was used to iden-tify active site residues likely togovern substrate binding and regio-specific catalysis. The functional significance of these residues was assessed using site-directedmutagenesis.
