Due to an increasing incidence rate, the need for new effective methods for diagnosing cancer are of high importance. Studies have shown that circulating tumor cells, CTCs, have great potential as a diagnostic biomarker. Acoustophoresis is a label free method, capable of separating CTCs from red blood cells in a blood sample. In theory, this would enable better CTC detection than the gold standard
Environmental problems are said to be research dependent, as science is needed to identify phenomena such as climate change. New technological cures are however often characterised by both research dependence and scientific uncertainty. One example is Biofuels. A few years back they were seen as a sustainable solution to the transport sector's carbon dioxide emissions and oil dependence. Since
The Radio Frequency Identification (RFID) is quite a vast subject. It is used for so many different applications. The most developed area of research has first been to track animals. Nowadays, many pets have a chip hidden in their neck that permits to identify them very specifically as the information in the chip is unique. Some researches have then been oriented on the supply chain area. Unfortu
While many industrial processes have been thoroughly exposed to machine learning models, the realm of powder metallurgy is still underexplored. This thesis aims to investigate the potential for a machine learning model to predict the characteristics of metal powders after a reduction annealing process using time series process data from the furnace. A supervised learning model was developed to pre
One of the most interesting features of nuclei is the process by which specific configurations, manifest as collective rotational bands at intermediate spin values, gradually lose their collectivity and terminate in a non-collective state at the maximum spin which can be built within the configuration. Recent advances in both experiment and theory allow the study of this nuclear structure feature
This thesis examines how safety is governed in urban policy by analysing the municipality of Groningen’s renewed Actieplan Veilig Uitgaan 2025. Bacchi’s What is the problem represented to be? (WPR) approach is applied to deconstruct how the action plan represents safety as a governance problem, what assumptions make this representation possible, and what is left unproblematised. The analysis draws
Through practical experiments, edge-wear analysis, and the study of archaeological collections, the dissertation explores the complex relationship between style and function in a specific class of artifacts: the Neolithic axe. The results of the three-part approach described above, when applied for instance to thin-butted axes from the Funnel Beaker Culture, indicated that there was no clear-cut c
Popular Abstract in Swedish Paternalism i allmänläkarens vardag - om läkarens makt och patientens rätt till självbestämmande. I mitt vardagliga arbete som allmänläkare möter jag patienter med olika symtom och sjukdomar. Hur bör allmänläkaren förhålla sig till en patient som ställer krav på en åtgärd – en speciell undersökning, ett recept på en viss medicin eller ett intyg – som läkaren inte finneThe overall aim of this thesis was to identify and analyse situations raising the question of possible paternalism in everyday general practice in Sweden. Both questionnaires to a random sample of respondents and interviews have been used. The ethical awareness among GPs in Sweden and the variety of ethical issues, suggest that medical ethics is a subject of high relevance in general practice. Th
Sammanfattning-The use of hierarchical structures for providing excellent wireless connections for customers has attained growing attention. Models to investigate the QoS requirements rather quickly become complicated and hard to analyze. In the paper a first rough analytical approach for the answer is given. As the users devote more and more time to be connected through wireless connections, and
We present a detailed theoretical study of the electronic spectrum and Zeeman splitting in hole quantum wires. The spin-3/2 character of the topmost bulk-valence-band states results in a strong variation in subband-edge g factors between different subbands. We elucidate the interplay between quantum confinement and heavy-hole-light-hole mixing and identify a certain robustness displayed by low-lyi
We demonstrate a novel non-intrusive technique based on tunable diode laser absorption spectroscopy to investigate human maxillary sinuses in vivo. The technique relies on the fact that free gases have much sharper absorption features (typical a few GHz) than the surrounding tissue. Molecular oxygen was detected at 760 nm. Volunteers have been investigated by injecting near-infrared light fibre-op
Two main topics are dealt with in this thesis. Firstly, the performance of condensing boilers with finned tube heat exchangers and premix burners is evaluated. Secondly, ways of avoiding condensate formation in the flue system are evaluated. In the first investigation, a transient heat transfer approach is used to predict performance of different boiler configurations connected to different heati
The metallation of tetrapyrroles is believed to proceed via a sitting-atop (SAT) complex, in which some of the pyrrole nitrogen atoms are still protonated and the metal ion resides above the ring plane. No crystal structure of such a complex has been presented, but NMR and extended X-ray absorption fine structure (EXAFS) data has been reported for Cu2+ in acetonitrile. We have used density functio
We have employed time-resolved photoluminescence (PL) spectroscopy to study the impact of HfO2 surface capping by atomic layer deposition (ALD) on the optical properties of InP nanowires (NWs). The deposition of high-kappa dielectrics acting as a gate oxide is of particular interest in view of possible applications of semiconductor NWs in future wrap-gated field effect transistors (FETs). A high n
In order to correlate behavioural deficits to lesion size and to reveal possible functional asymmetries in the rat brain, locomotor activity, rotation and sensorimotor integration to touch were studied in spontaneously hypertensive rats (SHR) subjected to right or left middle cerebral artery occlusion. Control and infarcted rats showed no difference in locomotor activity. Infarcted rats tended to
The surrounding world, filled with objects, is the foundation of our actions, thoughts and emotions. Equally, we affect things and objects in our turn, through the interpretation and the significance we give them. In regard to old age, certain objects, as well as places, may become problematic. Some things lose their importance and fall out of use while others appear and become integrated in every
The mechanical failure of solid oxide fuel cell (SOFC) components may cause cracks with consequences such as gas leakage, structure instability and reduction of cell lifetime. A comprehensive 3D model of the thermal stresses of an anode-supported planar SOFC is presented in this work. The main objective of this paper is to get an interconnect optimized design by evaluating the thermal stresses of
Moderate to high palaeolatitudes recorded in mafic dykes, exposed along the coast of Bahia, Brazil, are partly responsible for some interpretations that the São Francisco/Congo craton was separate from the low-latitude Rodinia supercontinent at about 1050 Ma. We report new palaeomagnetic data that replicate the previous results. However, we obtain substantially younger U-Pb baddeleyite ages from f
