Background: Dizziness is the most common symptom in elderly patients and has been identified as a risk factor for falls. While BPPV is the most common cause of dizziness among elderly, multisensory deficits is the second, with visual, vestibular and proprioceptive reduced function. Asymmetric vestibular function is overrepresented in elderly persons with hip fractures and wrist fractures and can b
Transcriptional factors of the GntR family regulate numerous physiological and morphological processes in response to the nutrient state of bacterial cells. The number of GntR transcriptional factors in genomes of soil-dwelling actinomycetes is one of the highest among bacteria, reflecting both the large size of their chromosomes and the complex ecological niche that they occupy. However, very lit
In this study, a potentiometric glucose biosensor was fabricated by immobilization of glucose oxidase on to zinc oxide nanowires. Zinc oxide nanowires with 250-300 nm diameters and approximately 1.2 mu m lengths were grown on the surface of silver wires with a diameter of 250 mu m. Glucose oxidase (GOD) was electrostatically immobilized on the surface of the well aligned zinc oxide nanowires resul
Fischer-Tropsch (FT) synthesis is an important process in the manufacturing of hydrocarbons and oxygenated hydrocarbons from mixtures of carbon monoxide and hydrogen (syngas). The reduced iron catalyst reacts with carbon monoxide and hydrogen to form bulk Fe5C2 Hagg carbide (chi-HC) during FT synthesis. Arguably, chi-HC is the predominant catalyst phase present in the working iron catalyst. Deacti
Phosphonated polymers with a well-defined molecular weight, composition, and architecture have been prepared via ring opening metathesis polymerization (ROMP) of diethyl phosphonate norbornene imides at room temperature for the first time. ROMP gave a broad range of phosphonated homopolymers, statistical, diblock and triblock copolymers based on poly(norbornene imide)s with low polydispersity (1.0
Background A minority of patients with adult acute lymphoblastic leukemia who relapse are rescued. The aim of this population-based study was to assess the results of reinduction treatment and allogeneic stem cell transplantation in patients in second complete remission. Design and Methods Between 2003-2007, 76 adults (<66 years) with relapsed acute lymphoblastic leukemia (Burkitt's leukemia exclu
It is now widely accepted that globular cluster red giant branch (RGB) stars owe their strange abundance patterns to a combination of pollution from progenitor stars and in situ extra mixing. In this hybrid theory a first generation of stars imprints abundance patterns into the gas from which a second generation forms. The hybrid theory suggests that extra mixing is operating in both populations a
The overall aim of this thesis was to elucidate fathers’ experience of becoming parents of a pretermborn infant as well as their experience in the years after their infant’s birth. A further aim was to describe the context of neonatal care by investigating trends in outcome during a ten-year period in the southern region of Sweden. In total twenty-one fathers were interviewed at three different ti
We used novel Global Positioning System-based satellite telemetry to reconstruct daily time budgets on travelling days of a long-distance migrant, the Osprey Pandion haliaetus, to reveal how landscape affects migratory performance. We compared daily travel routines between the Ospreys' passage of Europe and the Sahara. In Europe, where feeding habitat is abundant, Ospreys fed both before-after fli
In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 (2-state) convolutional encoder with generator matrix G(D)=(1 1+D) when used to communicate over the binary symmetric channel. Their formula was later extended to the rate R=1/2, memory m=2 (4-state) convolutional encoder with generator matrix G(D)=(1+D^2 1+D+D^2) by Lent
The growth of Mn nanostructures on a 1D grating of silicon nano-ribbons is investigated at atomic scale by means of scanning tunneling microscopy, low energy electron diffraction and core level photoelectron spectroscopy. The grating of silicon nano-ribbons represents an atomic scale template that can be used in a surface-driven route to control the combination of Si with Mn in the development of
I lavbulletinen 2014:2 skrev Ulf om en skånsk hotspot för stenlavar och rapporterade också om en obestämd Lecidea. Den har nu blivit bestämd till L. variegatula och det visade sig att det var en ny art för Norden. Här beskrivs den kortfattat än en gång.
Interventions enabling aging individuals to fulfill their plastic potential promise to postpone, attenuate, or even reverse the adverse effects of senescent brain changes on cognitive abilities and everyday competence in old age. Based on an overview of the concept of plasticity in lifespan development, we selectively review evidence from cognitive intervention studies and conclude that most of th
The Gaia-ESO survey is a large public spectroscopic survey aimed at investigating the origin and formation history of our Galaxy by collecting spectroscopy of representative samples (about 105 Milky Way stars) of all Galactic stellar populations, in the field and in clusters. The survey uses globular clusters as intra-and inter-survey calibrators, deriving stellar atmospheric parameters and abunda
Effective attractions between colloidal particles bearing a grafted poly(ethylene glycol) (PEG) layer in water have been studied and quantified by measurements of the collective diffusion coefficient and by quantitative analysis of small-angle neutron scattering (SANS) data. Results for the collective diffusion coefficient in the dilute limit indicate that effective attractions develop gradually a
The studies in this thesis are based on questions raised in the clinical setting. Perioperative myocardial ischemia occurs more often than recognized. This may lead to myocardial infarction, increased morbidity, mortality, and health care costs. In the first study, myocardial metabolism was investigated before, during, and after 30 min of regional coronary artery occlusion, utilizing the microdi
