The epidermal growth factor receptor (EGFR) and the estrogen receptor (ER) modulator Amplified In Breast cancer-1 (AIB1) have been reported to be of importance for the prognosis of breast cancer patients. We have analyzed AIB1 and EGFR by immunohistochemistry in primary breast cancers (n = 297) arranged in a tissue microarray in order to predict outcome after adjuvant endocrine therapy with tamoxi
This thesis measures cost efficiency in the production of health care and social services in Sweden. The object of analysis is not provider efficiency, but instead the relative efficiency of political organizations or different contractual arrangements. The thesis focuses on: 1) the measurement of cost efficiency, 2) the investigation of potential trade-offs between quantity of health care service
Novel magneto-resistive memory effect is demonstrated, which appears in lithographically patterned Y-shaped, three-terminal nanostructures, consisting of three nanowires joined in one point, formed in the epitaxial layer of a ferromagnetic (Ga, Mn) As semiconductor. The effect, in which the zero-field resistance of a pair of nanowires depends on the direction of the previously applied magnetic fie
A transceiver suitable for devices in wireless body area networks is presented. Stringent requirements are imposed by the high link loss between opposite sides of the body, about 85 dB in the 2.45 GHz ISM band. Despite this, minimum physical size and power consumption are required, and we target a transceiver with 1 mm2 chip area, 1 mW active power consumption, and data rate 250 kbit/s. The receiv
Methanol oxidation to formaldehyde was studied over a series of Fe-Mo-O catalysts with various Mo/Fe atomic ratio and the end compositions Fe2O3 and MoO3. The activity data shows that the specific activity passes through a maximum with increase of the Mo content and is the highest for Fe2(MoO4)3. The selectivity to formaldehyde, on the other hand, increases with the Mo content in the catalyst. A s
The classical Stern-Gerlach experiment is analyzed with an emphasis on the spin dynamics. The central question asked is whether there occurs a relaxation of the spin angular momentum during the time the particle passes through the Stern-Gerlach magnet. We examine in particular the transverse relaxation, involving angular momentum exchange between the spin of the particles and the spins of the magn
Nielsen RE, Levander S, Thode D, Nielsen J. Effects of sertindole on cognition in clozapine-treated schizophrenia patients. Objective: To assess the cognitive effects of sertindole augmentation in clozapine-treated patients diagnosed with schizophrenia. Cognition is secondary outcome of the trial. Method: A 12-week, double-blinded, randomized, placebo-controlled, augmentation study of patients tre
Reflective writing enhances personal and professional development. It is essential for the teachers to be familiar with the students' perceptions to improve the students' learning. Our aim was to deepen the understanding of the medical students' perceptions of the studies and the coming profession.
Pluralistic ignorance is a socio-psychological phenomenon that involves a systematic discrepancy between people’s private beliefs and public behavior in certain social contexts. Recently, pluralistic ignorance has gained increased attention in formal and social epistemology. But to get clear on what precisely a formal and social epistemological account of pluralistic ignorance should look like, we
We have investigated a large set of individual wurtzite/zinc-blende GaAs heterojunction nanowires using transmission electron microscopy (TEM), photoluminescence (PL), and cathodoluminescence (CL). In several cases we have combined PL and TEM on the same wire. We find a fairly deep emission that shows a strong blueshift with increasing excitation power density. By using a variety of experiments we
Organic phosphorus (P) compounds represent a major component of soil P in many soils and are key sources of P for microbes and plants. Solution NMR (nuclear magnetic resonance spectroscopy) is a powerful technique for characterizing organic P species. However, P-31 NMR spectra are often complicated by overlapping peaks, which hampers identification and quantification of the numerous P species pres
The ATLAS liquid argon calorimeter has been operating continuously since August 2006. At this time, only part of the calorimeter was readout, but since the beginning of 2008, all calorimeter cells have been connected to the ATLAS readout system in preparation for LHC collisions. This paper gives an overview of the liquid argon calorimeter performance measured in situ with random triggers, calibrat
Fresh water from Lake Svartsjon, Sweden, was collected and four fractions were prepared: (1) adsorption on DEAE, (2) flocculation with Ca2+, (3) co-precipitation with Fe hydrous oxide and (4) co-precipitation with Mn hydrous oxide. The plutonium level in the lake is 65 fg/l (222 mu Bq/l), measured by ICP-QMS and ICP-SFMS. Pronounced accumulation in fractions (1) (34%) and (2) (66%), combined with
OBJECTIVE - Our aim was to characterize familial risks for type 2 diabetes by the type and number of affected family members, including half-siblings, adoptees, and spouses, to quantify risks and estimate the contribution of environmental effect. RESEARCH DESIGN AND METHODS - Families were identified from the Multigeneration Register, and type 2 diabetic patients were obtained from the Hospital Di
In many vertebrate radiations, food partitioning among closely related taxa is a key factor in both the maintenance of species diversity and the process of diversification. We compared diet composition and jaw morphology of 18 New Zealand triplefin species (F. Tripterygiidae) to examine whether species have diversified along a trophic axis. These fishes predominantly utilised small, mobile benthic
A series of palladium(II) and platinum(II) complexes ([PdCl2(J003)] (1), [PdCl2(W001)] (2), [PtCl2(J003)] (3) and [PtCl2(W001)] (4), where J003 = the Josiphos ligand (R)-1-[(S)-2-diphenylphosphino)ferrocenyl]ethyldicyclohexylphosphine and W001 = the Walphos ligand (R)-1[(R)-2-(2'-diphenylphosphinyl) ferrocenyl]ethyldo(bis-3,5-trifluoromethylphenyl)phosphine), were prepared from the reaction of the
Using diluted methane/air mixtures in internal combustion engines has a potential of reducing emissions and increasing efficiency. However, the ignition systems used today show difficulties igniting lean mixtures. For this purpose a new high frequency (HF) ignition system using pulse generators and a resonance circuit to achieve a controlled number of sparks during a controlled period of time has
This paper presents the design of an embedded automated digital video surveillance system with real-time performance. Hardware accelerators for video segmentation, morphological operations, labeling and feature extraction are required to achieve the real-time performance while tracking will be handled in software in an embedded processor. By implementing a complete embedded system, bottlenecks in
In recent times, archaeological documentation strategies have been considerably improved by the use of advanced 3D acquisition systems. Laser scanning, photogrammetry and computer vision techniques provide archaeologists with new opportunities to investigate and document the archaeological record. In spite of this, the amount of data collected and the geometrical complexity of the models resulting
Hemolytic uremic syndrome (HUS) is the most common cause of acute renal failure in children in the western world. HUS is characterized by the triad of hemolytic anemia, thrombocytopenia and renal failure. There are two main subtypes of HUS; typical or D+ (D stands for diarrhea) HUS associated with enterohemorrhagic E. coli (EHEC) infection, which accounts for about 90% of all HUS cases, and atypic
