Electrokinetically Driven Mixing in a Microchamber for Lab-on-a-Chip Applications Narayan Sundaram Abstract Micro-Total-Analysis-Systems (μTAS) have been the focus of recent world wide research due to their varied applications. Much of the motivation for the development of μTAS stems from applications in biotechnology and biomedicine. A typical μTAS device includes a number of functional units ranging from sample injection or ingestion, pre-concentration, mixing with reagents, chemical reactions, separation, detection, and possibly a chemical response. Mixing of constituents is one of the key functions desired of these systems for conducting analyses in a short span of time. The flow regime in these small devices (typical sizes 100μm) being predominantly laminar (Reynolds number, Re < 1), it becomes difficult to rapidly mix the constituent species. Hence for effective mixing, it is necessary to increase the Reynolds number and/or induce bulk motion such that the material interface between the components to be mixed is continously augmented. The method developed to induce such motion is by the application of an AC fluctuating potential field across a microchamber in which mixing is to be performed. The externally applied electric field applies a force on free ions in the charged Debye layer very close to the surface (1-10 nanometers) and induces a flow velocity which is proportional to the electric field. This applied fluctuating electric field gives rise to hydrodynamic instabilities which are responsible for increasing the material contact surface and hence augmenting the rate of mixing by an order of magnitude or more over pure diffusion. To further enhance mixing, microbaffles are strategically placed inside the microchamber and the mixing time was further decreased by a factor of two. Mixing was also studied in a neutral (no charge on the walls) microchamber. It was found that the mixing achieved in the absence of surface charge was comparable to the mixing achieved in the case with microbaffles. This work establishes that CFD is a useful tool that is capable of providing insight into the flow physics in devices with very small length scales. / Master of Science

The overall aim of this thesis was to characterize patient-physician communication in oncology care with focus on the content and quality of the consultations from the perspectives of patients, oncologists and observer. Further, the aim was to explore oncologists’ perceived barriers against psychosocial communication in out-patient consultations. Finally, the aim was to evaluate different methods for evaluating communication in this setting. Routine oncology out-patient consultations from two different hospitals were audio-recorded. After the consultations, patients and oncologists perceptions of the content and quality of the communication were assessed using a self-report questionnaire. A nation-wide survey was performed to assess oncologists’ perceived barriers against psychosocial communication. Finally, the audio-recorded consultations were used for evaluating inter-rater reliability and feasibility of two different communication analysis instruments. Patient-physician consultations in oncology care are focused on the physical aspects of disease and treatment, both in terms of how often these issues were discussed and in terms of the amount of time spent on discussing them. Psychosocial issues, such as the disease’s effects on patients’ emotional or social functioning, are not always discussed during consultations, and the time spent on such discussions is limited. When psychosocial issues are discussed during the medical consultations, they are most often patient-initiated. Reasons for why psychosocial aspects are seldom discussed during the medical consultations can be the barriers concerning this kind of communication perceived by a large majority (93%) of the oncologists. Barriers against psychosocial communication were identified at organizational levels (including guidelines, routines, and resources) and individual levels (including physicians’ knowledge and attitudes). Furthermore, this thesis shows that there are methods with high feasibility and reliability for evaluating the content of patient-physician communication, in large study samples in oncology care. The method (observation/self-report) and perspective (patient, physician, and observer) used when evaluating communication affects the results. This needs to be considered when choosing evaluation methods in intervention studies. There are reasons to continue to evaluate, promote and implement promising ways of achieving better communication in clinical practice. Research should focus on how to overcome barriers against psychosocial communication.

KISS (Kinematic Support System) is a locally developed gait analysis system at Middle East Technical University (METU), and the performance of the system was evaluated before as a whole. However, such evaluations do not differentiate between the efficacy of the data acquisition system and the model-based gait analysis methodology. In this thesis, kinematic results of the KISS system will be compared with those of the Ankara University based commercial VICON (Oxford Metrics Ltd., Oxford, UK) system, in view of evaluating the performance of data acquisition system and the gait analysis methodology separately. This study is expected to provide guidelines for future developments on the KISS system.

Population projection matrix (PPM) models are a central tool in ecology and evolution. They are widely used for devising population management practises for conservation, pest control, and harvesting. They are frequently employed in comparative analyses that seek to explain demographic patterns in natural populations. They are also a key tool in calculating measures of fitness for evolutionary studies. Yet, demographic analyses using projection matrices have, in some ways, failed to keep up with prevailing ecological paradigms. A common focus on long-term and equilibrium dynamics when analysing projection matrix models fits better with the outmoded view of ecosystems as stable and immutable. The more current view of ecosystems as dynamic and subject to constant extrinsic disturbances has bred new theoretical advances in the study of short-term &quot;transient&quot; dynamics. Transient dynamics can be very different to long-term trends, and given that ecological studies are often conducted over short timescales, they may be more relevant to research. This thesis focuses on the study of transient dynamics using population projection matrix models. The first section presents theoretical, methodological and computational advances in the study of transient dynamics. These are designed to enhance the predictive power of models, whilst keeping data requirements to a minimum, and borrow from the fields of engineering and systems control. Case studies in this section provide support for consideration of transient dynamics in population management. The second section applies some of these new methods to answer pertinent questions surrounding the ecology and evolution of transient dynamics in plants. Results show that transient dynamics exhibit patterns according to life form and phylogenetic history. Evidence suggests that this can be linked to the stage-structuring of life cycles, which opens up the possibility for new avenues of research considering the evolution of transient dynamics in nature.
