Besides the convenience of oral use, other benefits were achieved with the new drug, with faster therapeutic responses and increased survival, giving the CML similar characteristics as chronic diseases. In this scenario, there was another challenge, drug compliance, since a significant proportion of patients fail to ingest all the prescribed doses of imatinib. The concern was to optimize the adherence of CML patients, the hematology ambulatory at the Clinical Hospital of the Federal University of Goias (HC-UFG), led the authoress to create a film cartoon, as a pro-adhesion educational intervention model. To investigate the effectiveness of this new educational material, we used in 65 patients three adherence measures, two indirect (Morisky Test and Molecular Response [MR]) and direct (plasma dosage of IM), before and after the screening of film. In univariate analysis, from the Morisky Test, the film was striking, with increased adherent patients, which increased from 15 (23.1%) to 43 (66.1%). The results of MR showed an improvement trend after the movie, because the positive molecular response (major MR or complete MR) increased from 81.5% to 86.1%. Regarding the serum levels of IM, with daily doses of 400-800 mg IM, the premovie samples showed higher average than the post-movie (2473.16 ± 1049.55 ng/ml versus 1414.72 ± 715 73 ng/ml), with a variation coefficients interpatients of 43.4% and 50.6%, respectively. This high dispersion index found has been reported by other authors. By multivariate analysis, patients were divided into three groups. The first brought together compliant patients before and after the film with a good therapeutic response (major MR) after the intervention. It was: patients over 53 years old, females, with associated diseases before and after the treatment of CML that use more than two drugs in addition to imatinib. The second group was marked by the change of not adherence pre to adherence post-film. Its features were younger than or equal to 53, the absence of other disease before the CML, the use of less than two drugs and complete molecular response after the film. In the third group, we observed patients without molecular response before and after the educational intervention and no medication adherence after the film. They had in common their age (less than or equal to 53 years), and drug discontinuation due to adverse reactions. The last represents the set of patients resistant to the educational film, drawing attention to the fact that only one pro-adhesion method may be insufficient for all individuals. It is concluded that medication adherence was higher among patients older than 53 years, the educational film is an effective proadhesion assistance and continuing education, if combined with another method, it could help maintain or enhance the benefits achieved in this work. / O tratamento da leucemia mielóide crônica (LMC) mudou radicalmente com o advento do mesilato de imatinibe (MI). Além da comodidade do uso oral, outros benefícios foram alcançados com o novo fármaco, como respostas terapêuticas mais rápidas e aumento da sobrevida, dando `a LMC características semelhantes `as de doenças crônicas. Neste cenário, surgiu outro desafio, a adesão medicamentosa, pois uma proporção significativa de pacientes deixa de ingerir a dose prescrita de imatinibe. A preocupação em otimizar a adesão dos pacientes com LMC, do Ambulatório de Hematologia do Hospital das Clínicas da Universidade Federal de Goiás (HC-UFG), motivou a autora a criar um filme em desenho animado, como modelo de intervenção educativa pró-adesão. Para investigar a eficácia deste novo material educativo, empregou-se, em 65 pacientes, três medidas de adesão, duas indiretas (Teste de Morisky e Resposta Molecular [RM]) e uma direta (dosagem plasmática do MI), antes e depois da exibição do filme. Em análise univariada, pelo teste de Morisky, o filme foi impactante, com aumento dos pacientes aderentes, que passaram de 15 (23,1%) para 43 (66,1%). Os resultados da RM indicaram uma tendência de melhora após o filme, pois a resposta molecular positiva (RM maior ou RM completa) passou de 81,5% para 86,1%. Em relação `a dosagem sérica do MI, com doses diárias entre 400-800 mg de MI, as amostras pré-filme apresentaram média superior `as do pósfilme (2.473,16 ± 1.049,55 ng/ml versus 1.414,72 ± 715,73 ng/ml), com coeficientes de variação interpaciente de 43,4% e 50,6%, respectivamente. Este elevado índice de dispersão encontrado tem sido relatado por outros autores. Pela análise multivariada, os pacientes foram separados em três grupos. O primeiro, reuniu os pacientes aderentes antes e após o filme e com boa resposta terapêutica (RM maior) após a intervenção. Foram eles: os doentes com mais de 53 anos, do gênero feminino, com doenças associadas antes e após o tratamento da LMC e que usam mais de dois medicamentos além do imatinibe. O segundo grupo foi marcado pela mudança de não adesão pré para adesão pós-filme. Suas características foram idade menor ou igual a 53, ausência de outra doença antes da LMC, uso de menos de dois medicamentos e resposta molecular completa pós-filme. No terceiro grupo, observou-se pacientes sem resposta molecular antes e depois da intervenção educativa, bem como não adesão medicamentosa após o filme. Eles tinham em comum a idade, menor ou igual a 53 anos, e suspensão do medicamento por reação adversa. Estes últimos representam o conjunto de pacientes resistentes ao filme educacional, chamando atenção para o fato de que somente um método pró-adesão pode ser insuficiente para todos os indivíduos. Conclui-se que a adesão medicamentosa foi maior entre os pacientes maiores de 53 anos, que o filme educativo é uma intervenção pró-adesão eficaz e que a educação continuada, aliada a outro método, poderia ajudar a manter ou ampliar os benefícios conquistados neste trabalho.

In this work the model ASAM is enriched with new eddy viscosity based dynamic Smagorinsky subgrid-scale models. Therefore the model is more physically based to study atmospheric flow configurations at several atmospheric scales with main focus to urban scale flow with building-resolved resolution. The implemented dynamic procedures work well and showed good agreement to literature data. In a convective atmospheric boundary layer (ABL) the dynamic Smagorinsky coefficient reaches maximum values of 0.15 and decreases towards the surface or in stable stratified flow regimes. Vertical profiles of the Smagorinsky coefficient in a diurnal cycle of ABL depict typical behaviour of the dynamic Smagorinsky coefficient in near surface flow, free-stream, or stable stratified flow. Furthermore a modified inflow generation approach is proposed to produce fully turbulent flow fields. To modify a mean flow turbulent fluctuations are generated by superposition of sinusoidal and cosinesoidal modes. Due to the implementation of this inflow method the model ASAM has the ability to reproduce a given wind field with information from its mean wind speed and their fluctuation energy spectrum. The model configuration developed in this work is able to reproduce flow structure in a complex urban geometry. The Mock Urban Setting Test (MUST) experiment represent an urban roughness geometry by placing 120 shipping containers ordinary arranged in an array. The used building-resolved resolution is able to capture dynamic flow structures like specific wake flow, recirculation regions or eddy detachment. The dynamic fluctuating behaviour of the wind velocity components is reproduced by the model with regard to peak magnitudes and their temporal occurrence. Satisfying agreement is found between tracer gas dispersion field measurements and the model results by capturing the fluctuating concentration magnitude and in some extend the mean values.:1 Introduction 1 2 Fundamentals of Large-Eddy Simulation in atmospheric boundary layers 7 2.1 The atmospheric boundary layer . . . . . . . . . . . . . . . . . . . . . 7 2.2 Atmospheric turbulence . . . . . . . . . . . . . . . . . . . . . . . . . 8 2.3 Basic equations of LES . . . . . . . . . . . . . . . . . . . . . . . . . . 9 3 Subgrid-scale modelling 15 3.1 Eddy viscosity subgrid-scale models . . . . . . . . . . . . . . . . . . . 15 3.1.1 Smagorinsky subgrid-scale model . . . . . . . . . . . . . . . . 16 3.1.2 Dynamic Smagorinsky subgrid-scale model . . . . . . . . . . . 18 3.1.3 Scale-dependent dynamic Smagorinsky subgrid-scale model . . 23 3.2 Implementation in the All Scale Atmospheric Model (ASAM) . . . . . 26 3.2.1 General description of ASAM . . . . . . . . . . . . . . . . . . 26 3.2.2 Subgrid-scale modelling in ASAM . . . . . . . . . . . . . . . . 27 3.3 Applications to meteorological situations . . . . . . . . . . . . . . . . 37 3.3.1 Stable and unstable stratified atmospheric boundary layers . . 37 3.3.2 Flow over periodic sinusoidal hill . . . . . . . . . . . . . . . . 49 4 Generation of turbulent inflow conditions 51 4.1 The necessity of turbulent inflow . . . . . . . . . . . . . . . . . . . . 51 4.2 Synthetic turbulent inflow generation method . . . . . . . . . . . . . 53 4.3 Implementation . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 55 4.4 2D simulation results . . . . . . . . . . . . . . . . . . . . . . . . . . . 57 5 Mock Urban Setting Test Experiment (MUST) 65 5.1 Micro-scale urban simulation . . . . . . . . . . . . . . . . . . . . . . . 65 5.2 Description of the experiment . . . . . . . . . . . . . . . . . . . . . . 68 5.3 Wind tunnel measurenments of MUST . . . . . . . . . . . . . . . . . 70 5.4 Numerical MUST simulation with ASAM . . . . . . . . . . . . . . . . 72 5.4.1 Choice of initial condition . . . . . . . . . . . . . . . . . . . . 75 5.4.2 Results of simulating case 2682353 . . . . . . . . . . . . . . . 81 5.4.3 Results of simulating case 2681829 . . . . . . . . . . . . . . . 98 5.4.4 Case resume . . . . . . . . . . . . . . . . . . . . . . . . . . . . 109 6 Summary and outlook 111 6.1 Summary . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 111 6.2 Outlook . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 114 7 Bibliography 117 List of Figures 127 List of Tables 135 Acronyms 137 Nomenclature 139 Acknowledgement 143 List of Publications 145

In this thesis, we have evaluated a stochastic Lagrangian model for computing particle deposition rates with prospects to use for atmospheric deposition applications.  The model is one-dimensional and models the particle dynamics in the boundary layers near walls and obstacles by simulating the coherent turbulent structures and Brownian motion governing the wall-normal transport. The deposition model is used with a hybrid deterministic/stochastic particle dispersion model governing the dynamics in the turbulent bulk flow. We used a steady-state RANS k-ϵ turbulence model to simulate the turbulent fluid flow in a neutral atmospheric boundary layer (ABL) using the with inflow boundary conditions by Richards & Hoxey (1993). The turbulence model is solved with the SIMPLE algorithm using the OpenFOAM software. The mean-field characteristic of the turbulent flow in the computational domain is exported and used for the particle model. The particle model is a Lagrangian Langevin-type model, consisting of a system of stochastic differential equations. The particle model was solved using a weakly first order a-stable scheme. We evaluated the deposition model by computing the deposition rate for a range of particle sizes and compared our results with collected experimental wind tunnel data. The numerical experiment was done in a computational domain based on the ABL model by Hargreaves & Wright (2007), a rectangular domain with a logarithmic wind profile. We used a particle source near the inflow boundary with an instantaneously release at the initial time. Results showed disagreement with the experimental data and was only valid for medium sized particles. However, time restrictions led to the analysis being cut short and only a single simulation was conducted. A definite conclusion on the suitability of the method could not be made based solely on this single results. Some uncertainties were identified and discussed for further potential work on the evaluation of the method. However, one conclusion was drawn on the performance of the method. The computational cost was concluded to be too high with the first order particle scheme used and higher order schemes is required for any practical use of the method for atmospheric deposition applications.

The stock market has proven to offer satisfactory means of raising capital for public companies. One behaviour that rather frequently can be observed is that companies on the stock market are becoming the subject of so-called takeover-offers. Immediately upon the commencement of a takeover-process the board of directors of a target-company is responsible for certain obligations stipulated in the legal framework for the stock market. An obligation of quite substantial significance for the shareholders in the target-company is the board of directors’ duty to make a statement on the takeover-offer. Since the said statement is of such significance for the shareholders, the question arises whether the board of directors can be held liable for irresponsible statements with regards to an imminent takeover-offer. This thesis aims to answer this question whilst examining closely related questions such as which obligations the board of directors has when making a statement on a takeover-offer as well as what basis of liability is applicable to the board of directors. Due to the nature of the Swedish capital market regulation the thesis also aims to illustrate and problematize the relationship between legislation and what is commonly referred to as self-regulation. By the means of a legal dogmatic method the thesis concludes that the boards of directors in some cases are liable for their statements on a takeover-offer. The conditions for which a basis of liability is applicable differs depending upon which ground of liability is chosen to establish said liability, this circumstance turns out to be of critical importance in a procedural sense. Although the basis of liability differs from one another the thesis displays that legitimate reasons speak for basing a claim for damages on the rule regarding tortious liability that the Swedish Supreme Court (Högsta domstolen) has developed. In addition to how the board of directors can be held liable the research has also demonstrated the importance of the statements the board of directors make on a takeover-offer. This provides support to the belief that the board of directors should be able to be held responsible for careless statements with regards to an impending takeover-offer. Furthermore, the research shows that a lack of distinct conjunction between self-regulation and legislation could generate an inconsistent construction of what the content of the current law is at any given time.

The atmospheric boundary layer (ABL) is the lowest layer of the atmosphere where surface effects are felt on time scales of about an hour. While its properties are determined by the surface characteristics, season and synoptic conditions, they in turn determine convective cloud properties and are required for the representation of cloud processes in atmospheric models. Further, interaction of the ABL with the surface layer of the ocean is a key component of ocean-atmosphere coupling. ABL characteristics over ocean surrounding the sub-continent become very important for understanding the monsoon processes during the monsoon season because the roots of many monsoon systems, that give rain to India, are over there. In this thesis data used are from three major field experiments namely the Bay of Bengal Monsoon Experiment (BOBMEX, 1999), Arabian Sea Monsoon Experiment (ARMEX, in two phases, ARMEX-I during 2002 and ARMEX-II in 2003), and Continental Tropical Convergence Zone (CTCZ) experiment (Pilot in 2009) which were carried out under the Indian Climate Research Programme (ICRP). While there have been few studies on ABL characteristics for individual cruises, a comprehensive study considering all available radiosonde data from the above cruises has been missing. This study fills this gap and focuses on the vertical structure of ABL using more than 400 high resolution Vaisala GPS radiosonde data collected over Bay of Bengal and Arabian Sea. The study attempts at first to look at the ABL characteristics of individual cruises and then compare and contrast them over the Bay of Bengal and Arabian Sea. ABL height Hm, estimated by using virtual potential temperature (θv) profile, shows diurnal variation during weak phase of convection while maximum in early morning during active phase of convection. Different variables i.e. moist static energy (h), specific humidity (q), convective available potential energy (CAPE), virtual potential temperature (θv) and equivalent potential temperature (θe) also differ during weak and active convection periods. Conserved variables mixing line approach gives the height up to which ground thermals penetrate in the vertical. This height, denoted by MH that represents the actual ABL height, is 2-3 times larger than Hm when shallow convective clouds are present. In general both Hm and MH are 20-30% larger over Arabian Sea compares to that over Bay of Bengal. Comparison of surface convective available potential energy (CAPE) and equivalent potential temperature (θe) between normal and deficit monsoon years shows that convective instability was as large in deficit years. This means that dynamic and not thermodynamics, controlled the occurrence of convection.
