Abstract:

The aims of this thesis are to develop and validate a robust and efficient algorithm for the numerical solution of the equations of General Relativistic Hydrodynamics, to implement the algorithm in a computationally efficient manner, and to apply the resulting computer code to the problem of perturbed Bondi-Hoyle-Lyttleton accretion onto a Kerr black hole. The algorithm will also be designed to evolve the space-time metric, and standardised tests will be applied to this aspect of the algorithm. The algorithm will use up-to-date High-Resolution Shock-Capturing numerical schemes that have been d

Excess thermodynamic properties have been determined for several binary liquid mixtures with the aim of testing various thermodynamic theories and postulates. Excess molar enthalpies, HEm, have been determined using an LKB flow microcalorimeter and excess molar volumes, VEm, have been determined using an Anton Paar vibrating tube densitometer. The activity coefficients at infinite dilution ƴ∞₁₃, have been determined using an atmospheric pressure gas-liquid chromatograph. The excess molar enthalpies and the excess molar volumes have been measured at 298.15 K for systems involving the bicyclic c

Abstract:

Non-covalent interactions taking place in solution are essential in chemical and biological systems. The solvent environment plays an important role in determining the geometry and stability of interactions. This thesis examines aromatic stacking interactions, alkyl-alkyl interactions, edge-to-face aromatic interactions, halogen bonds and hydrogen…hydrogen interactions in solution. Chapter 1 briefly introduces the different classes of non-covalent interactions, in addition to the state-of-the-art models and methods for investigating these weak interactions. The chapter finishes with a focus on

Water has, however, been a mystery for many years due to the large number of unusual chemical and physical properties, e.g. decreased volume during melting and maximum density at 4 °C. The origin of the anomalies behavior is the nature of the hydrogen bond.

Abstract The correct three dimensional structures of proteins are essential for their ability to function properly. Proteins start to fold as soon as they are synthesized in the ribosomes from activated amino acids. Many secreted, cell-surface, secretory pathway and endoplasmic reticulum (ER) lumenal proteins have in their amino acid sequence cysteine residues which form intra- and intermolecular disulfide bridges that stabilize the overall fold of the proteins and protein complexes. The formation of correct disulfide bonds is a complex process which takes place within the ER. Protein disulfi

Gas-phase thermolysis is a long-known and well established method for the preparation of reactive species. It is, however, limited to relatively volatile substances, which are easily vaporised. In the present work, the solution-spray technique for preparative scale was developed. With this technique, it is possible to subject low-volatile substances, which hardly vaporise even under high-vacuum conditions, to gas-phase thermolysis. By utilising oil nozzles used in heating and burner systems, it was possible to integrate a stable solution-spray into the existing flash-vacuum-pyrolysis system. T

Spherically symmetric adiabatic accretion on to a BH is described by the accretion branch of Bondi solutions (Bondi 1952), because the BH acts like a mass sink. On the other hand, stars like NSs and white dwarfs (WDs), have surface and hence the infalling matter has to slow down at the surface. Due to the

This dissertation explains the puzzling negative relationship between changes in stock volatility and credit spreads of corporate bonds. This relationship has been encountered in some empirical studies but has remained unexplained in the theoretical literature, which unanimously suggests the opposite relationship.

On the one hand, higher asset volatility corresponds to lower future volatility of the firm's investments and lower credit spreads if the firm can r

The mass loss of reinforcement caused by corrosion not only reduces cross sectional area of the reinforcement but also the bond between the steel reinforcement and surrounding concrete. By reducing the bond between the reinforcement and surrounding concrete, at serviceability limit state, corrosion may lead to an increase crack width and deflection, while at the ultimate limit state it may lead to reinforcement debonding.

Abstract:

Strengthening of concrete structures with a new concrete layer has been commonly used for columns, beams and slabs. This technique is economic and efficient for structural strengthening since it uses the same base materials, steel and concrete. It is usually applied on the compressed face of the concrete element due to concrete’s recognized behaviour under compression, posing several challenges to control cracking and resistance when applied on the tensile face. Strengthening of concrete structures with a new concrete layer applied on the tensile face requires controlling the debonding p

Abstract:

Spin crossover (SCO) active metal complexes are highly versatile materials thanks to their sensitivity to tiny physical or chemical environmental changes. This property makes them very useful for a wide range of applications: employable for experimental studies as molecular switches or for theoretical studies investigating the M-L bonds. In both cases, these studies aim to develop strategies of predictably tuning them. Chapter One. An introduction to the SCO phenomenon: from gradual to cooperative SCO; various methods of monitoring the SCO transition. A summary of some literature examples

Abstract:

Thesis titled, “Design, Synthesis and Conformational Analysis of Hydrogen Bond Surrogate (HBS) Stabilized Helices in Natural Sequences. Helically Constrained Peptides for Potential DNA-Binding”, describes the development of a novel covalent hydrogen bond surrogate (HBS) model and its incorporation in short (4-8 residues) unstructured peptide sequences with coded amino acids, through a facile solution phase synthetic method (SPSM), to constrain them into α- helical conformations with highest known stabilities and helicities. The synthetic protocol was developed for mass scale combinatorial synt

Abstract:

We firstly numerically recalculate the Ricci tensor of non-stationary axisymmetric space-times (originally calculated by Chandrasekhar) and we find some discrepancies both in the linear and non-linear terms. However, these discrepancies do not affect the results concerning linear perturbations of a Schwarzschild black hole. Secondly, we use these Ricci tensors to derive the Zerilli and Regge-Wheeler equations and use the Newman-Penrose formalism to derive the Bardeen-Press equation. We show the relation between these equations because they describe the same linear perturbations of a Sch

Celem rozprawy doktorskiej było przestawienie, co współczesna krystalografia może wnieść do badań minerałów o różnym stopniu wykształcenia, jakości kryształów. Badałem trzy rodzaje minerałów: (i) alumohydrokalcyt o słabo rozwiniętych igiełkowych kryształów (ii) minerały grupy czewkinitu, złożone roztwory stałe, często również metamiktyczne oraz (iii) fluoryt, którego kryształ był niemal doskonałej jakości.<br>The PhD dissertation presents what modern crystallography can deliver to the studies of minerals. Three types of minerals were studied (i) alumohydrocalcite of poorly developed tiny needl
