Résumé :

This study describes a detailed investigation of quantifying key micro-structural parameters of the unconsolidated granular media and their relationship with the grain shape factors calculated from micro-CT images. These parameters are combined with the contact based effective medium models to calculate the elastic properties of the constituent grains after utilising stress dependent ultrasonic velocities of the samples. Thus developed techniques produce good results for mono-mineral quartz sands and one of the poly-mineral rock powder.

The purpose of this study was to investigate four in-service physics teachers&rsquo<br>beliefs related to Turkish High School Physics Curriculum (THSPC) and to what extent these beliefs are reflected in their instructional practices. Data were collected through interviews, classroom observations and an open-ended questionnaire. Teachers&rsquo<br>responses to interview questions showed that they believed that teaching physics according to the THSPC helped students use their skills, become interested in physics lessons, relate physics to their daily life and have a permanent knowledge.

I then motivate and define a non-relativistic formulation (NRQCD) of the theory. I discuss the mechanics of the extraction of numbers from numerical simulations, and present general arguments as to the expected form of these data. I present results and details of their extraction from simulations of heavy-heavy and heavy-light mesons using NRQCD. I compare these results with those from other calculations an

Résumé :

In a process called 'base rivalry', irreparable mutations are provoked in the replication of monotonous sequences, which depend on the cell temperature, the cell viscosity and monotonous sequence length. This explains the very long monotonous sequences and very long DNAs that occur over long evolutionary epochs. Presumably, base rivalry (with tautomerism or too low cell viscosity) also provokes the formation of tumors and the emergence of dangerous viral mutations.

Résumé :

In a previous publication [1] the author described the base rivalry in monotonous DNA sequences and their effect on the DNA repair mechanism. As described in the article, during the monotonous sequence replication, energies appear theoretically to increase with a progressive replication fork up to the quantum mechanical energy level n=2 because of the base rivalry, and these rivalry energies affect the bond strength between the complementary bases. If there is a tautomeric base pair in the replication position where the rivalry energy is large enough, then in this position an irreparable muta

Physics education is facing a crisis of meaning: students can “plug” numbers into formulas, but research shows they do not give much meaning to physical concepts. This thesis explores how the cultural context of physics education, in particular the mind/body cartesian split, contributes to a loss of meaning. Drawing from sensory scholarship, cognitive linguistics, feminist critiques of science, her own teaching experience and education research on student misconceptions and intuitive knowledge, the author challenges the mind/body dichotomy by exploring how the body can make sense of the physic

These expressions, which are given in terms of input see-saw parameters, provide a useful guide for unified model building. We then evaluate these formulae in the cases of CSD and PCSD for two numerical GUT inspired models in order to measure the effect of NLO and NNLO corrections.

We study the small-z limit of the structure functions for deep inelastic scattering in Quantum Chromodynamics. The standard approach to this process, based on the DGLAP equations, runs into difficulties in the small-x region due to the higher order corrections becoming large. As an attempt to overcome these obstacles we reinterpret the small-z limit in terms of high energy asymptotics. The relevant high energy formalism is developed in terms of Reggeon Field Theory, which leads to the BFKL equation for the scattering amplitude. These results are reviewed fully, for completeness.

Two assumptions pervade contemporary metaphysics: that there is a fundamental level to reality, and that physics will one day describe it. In the first part of this thesis, I consider whether physics may have a greater role for fundamentality metaphysics than that which it is typically accorded. In particular, I consider whether physics might contribute not just to questions of the content of an assumed fundamental level, but to the existence of such a level itself. I argue that if we are to use physics to do such a thing, it must be through what I call the 'internal' approach, in which fundam

Equipped with the philosophical background we then propose a mathematical realization by representing the dynamics with a non-trivial elementary embedding from the mathematical universe to itself.

However, the benefit of including inclusive-jet cross-section data from ATLAS in global fits is only significant if the jet energy scale (JES) can be constrained to ~1% at high pT.

Résumé :

Inspired by the recast of the quantum mechanics in a toposical framework, we develop a contextual quantum mechanics via the geometric mathematics to propose a quantum contextuality adaptable in every topos. The contextuality adopted corresponds to the belief that the quantum world must only be seen from the classical viewpoints à la Bohr consequently putting forth the notion of a context, while retaining a realist understanding. Mathematically, the cardinal object is a spectral Stone bundle Σ → B (between stably-compact locales) permitting a treatment of the kinematics, fibre by fibre and full

Résumé :

During the twentieth century, particle physics developed into a cornerstone of modern physics, culminating in the Standard Model. Even though this theory has proved to be of extraordinary power, it is still incomplete in several respects. It is our aim in this bachelor thesis to discuss some possible theories beyond the Standard Model, the main focus being on Grand Unified Theories, while also taking a look at attempts of further unication via discrete family symmetry. At the heart of all these theories lies the concept of local gauge invariance, which is introduced as a fundamental principle,
