In this paper, a technique for calibrating a camera using a planar calibration object with known metric structure, when the camera (or the calibration plane) undergoes pure translational motion, is presented. The study is an extension of the standard formulation of plane-based camera calibration where the translational case is considered as degenerate. We derive a flexible and straightforward way
Nuclear spin relaxation is a powerful method for studying molecular dynamics at atomic resolution. Recent methods development in biomolecular NMR spectroscopy has enabled detailed investigations of molecular dynamics that are critical for biological function, with prominent examples addressing allostery, enzyme catalysis, and protein folding. Dynamic processes with similar correlation times are of
In this investigation, we have collected family-structured data from a partly self-compatible, outcrossing population of Brassica cretica to estimate and compare the effects of one-generation selfing on different types of characters. Inbreeding not only depressed characters that should be positively correlated with fitness irrespective of habitat, e.g. germinability, leaf number and inflorescence
Objective: To study the association between mode of delivery and neonatal outcome in singleton pregnancy with breech presentation and preterm birth, due to premature tabour (PTL) and/or preterm premature rupture of the membranes (pPROM). Design and methods: Information on preterm (gestational week 25-36) singleton births in breech presentation in Sweden during 1990-2002 was obtained from the Swedi
The mechanism of formation of two different cubic mesoporous silica materials formed with Pluronic triblock copolymers is investigated with in situ time-resolved small-angle synchrotron X-ray scattering, in situ time-resolved H-1 nuclear magnetic resonance, and time-resolved transmission electron microscopy. The materials studied are the micellar cubic (Im (3) over barm) SBA-16 formed with Pluroni
Popular Abstract in Swedish Nästan 35% av den totala avrinningen i Gula floden härstammar från dess källområde och vattenförsörjningen nedströms är därför beroende av de rådande förhållandena i detta område. Minskad vattenföring i floden på grund av klimatförändringar förväntas leda till negativa konsekvenser för de 110 miljoner invånarna i avrinningsområdet och problem uppstår för såväl jordbrukeThe source region of the Yellow River contributes about 35% of the total water yield in the Yellow River basin playing an important role for meeting the downstream water resources requirements. The declining water availability caused by climate change in the source region of the Yellow River is expected to have severe repercussions for the 110 million basin inhabitants in terms of water resources
SNAP-25 is important for Ca(2+)-dependent fusion of Large Dense Core Vesicles (LDCVs) in insulin-secreting cells. Exocytosis is further enhanced by cAMP-increasing agents such as GLP-1 and this augmentation includes interaction with both PKA and cAMP-GEFII. To investigate the coupling between SNAP-25 and cAMP-dependent stimulation of insulin exocytosis we have used capacitance measurements, protei
The importance of the nurse's role in the management of patients with type 2 diabetes has long since been emphasized. The aim of this study was to test the hypothesis that a structured organization of type 2 diabetes care, with a diabetes nurse working more independently of the general practitioner, has a significant impact on the patient's self-management and quality of care. The test consisted o
Bone-metastatic, castration-resistant prostate cancer (bmCRPC) represents a lethal stage of the most common noncutaneous cancer in men. The recent introduction of Radium-223 dichloride, a bone-seeking alpha particle (α)-emitting radiopharmaceutical, demonstrates statistically significant survival benefit and palliative effect for bmCRPC patients. Clinical results have established safety and effica
Cancer of unknown primary (CUP) is a fatal disease diagnosed through metastases. It shows intriguing familial clustering with certain defined primary cancers. Here we examine whether metastatic location in CUP patients is related to primary non-CUP cancers in relatives based on the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for CUP patients defined by metastatic
This thesis deals with signatures in sediments on Earth related to the L-chondrite parent body break-up event at 470 Ma. The aim of this thesis is twofold: (1) investigate if the increased flux of extraterrestrial material to Earth, following the disruption of the L-chondrite parent body included larger, asteroid-sized bodies (2) try to develop new methods and tools for finding and classifying rel
The radiative lifetimes of the states in the (n=5-8) 3snp P-1(1) sequence of neutral magnesium were investigated using time-resolved laser-induced fluorescence. Excitation from the 3s2 S-1(0), ground state was performed using VUV radiation, which was produced by resonant sum-difference frequency mixing in a krypton gas cell. We find tau(n=5): 54(3) ns, tau(n=6): 140(10) ns, tau(n=7): 290(20) ns, t
Highly excited 2P levels in alkali atoms were populated using a multi-step excitation, involving a tunable dye laser. The hyperfine structure of the 9 2P level in 87Rb and the 11, 12 2P levels in 133Cs was determined with optical double resonance.
BACKGROUND: Huntington’s Disease (HD) is a hereditary, progressive neurodegenerative disorder characterised by both neurological and systemic symptoms. In HD, immune changes can be observed before the onset of overt clinical features raising the possibility that immune markers in plasma could be used to track disease progression. It has previously been demonstrated that a widespread, progressive i
Written French is known as a deep orthography, presenting important differences between the spoken and written language systems, especially as far as morphology is concerned. This exploratory study of subject-verb agreement in number illustrates the long and laborious differentiation process of spoken and written French in child learners. The focus of the study is the L2 child, who learns to speak
