Ground vibration from traffic is a source of nuisance in urbanized areas. Trenches and wave barriers can provide mitigation of vibrations, but single barriers need to have a large depth to be effective - especially in the low-frequency range relevant to traffic-induced vibration. Alternatively, periodic repetitions of mass, stiffness or both in an infinite structure lead to so-called stop bands in
Aims: To study the number, outcome and reasons for prenatal diagnosis (PND) and how it has affected the incidence of haemophilia, the number of siblings and the number of potential carriers in the families. Study Group: Women in SWE, compromising over 95% of total, who underwent PND of haemophilia during the years 1970-2010. A total of 46 women were identified who together underwent 79 PND procedu
Background-Diabetes mellitus (DM) and cardiovascular disease are associated with dyslipidemia, but the detailed lipid molecular pattern in both diseases remains unknown. Methods and Results-We used shotgun mass spectrometry to determine serum levels of 255 molecular lipids in 316 controls, 171 DM, and 99 myocardial infarction (MI) events from a cohort derived from the Malmö Diet and Cancer study.
OBJECTIVE: To compare the effects of care based on comprehensive geriatric assessment (CGA) as a complement to usual care in an outpatient setting with those of usual care alone. The assessment was performed 36 months after study inclusion.DESIGN: Randomized, controlled, assessor-blinded, single-center trial.SETTING: A geriatric ambulatory unit in a municipality in the southeast of Sweden.PARTICIP
Under electrochemical polarization, many electrocatalysts can undergo oxidation that alters their reactivity and can lead to restructuring and dissolution. In this context, the structure-property relationships of electrocatalysts, as well as their kinetics and dynamic behaviour, are still poorly understood. This knowledge gap mainly relies on the limitations of many traditional spectroscopic and s
A study of optical and transport properties of semiconductor quantum well structures subjected to nanoimprint lithography (NIL), with its pressure and temperature cycles, has been undertaken to ascertain if this lithography technique induces detrimental changes in these properties of the active layers over a range of pressures and temperatures, typically used in this printing process.

delta C-13 values of numerous limestone samples from Katian (Upper Ordovician) successions in Oklahoma and the Upper Mississippi Valley document the presence of at least three of the four positive excursions that have been recognized in the lower-middle Katian interval in the Cincinnati region in Ohio. Kentucky, and Indiana. A comparison with Estonia reveals that five out of the six positive excur
Mucosal tissues contain large numbers of memory CD4(+) T cells that, through T-cell receptor-dependent interactions with antigen-presenting cells, are believed to have a key role in barrier defense and maintenance of tissue integrity. Here we identify a major subset of memory CD4(+) T cells at barrier surfaces that coexpress interleukin-18 receptor alpha (IL-18Rα) and death receptor-3 (DR3), and d
BACKGROUND: Metformin use has been associated with improved survival in patients with different types of cancer, but research regarding the effect of metformin on cutaneous melanoma (CM) survival is sparse and inconclusive.OBJECTIVES: To investigate the association between metformin use and survival among patients with CM and diabetes.METHODS: All adult patients with a primary invasive CM between
We have performed extensive investigations of laser-induced fluorescence in animal and human tissue aimed at instant tissue characterization. Autofluorescence, as well as specific fluorescence from HPD/DHE and other photosensitizers, has been utilized. The studies have been focused on the demarcation of malignant tumours and atheroscleortic plaques. A nitrogen laser or an excimer-pumped dye laser
Biochemical signs and severity of symptoms of primary hyperparathyroidism (pHPT) differ among patients, and little is known of any coupling of clinical characteristics of nonfamilial pHPT to genetic abnormalities in the parathyroid tumors. Mutations in the recently identified MEN1 gene at chromosome 11q13 have been found in parathyroid tumors of nonfamilial pHPT. Using microsatellite analysis for
Background: Pesticides and metals may disrupt thyroid function, which is key to fetal brain development. Objectives: To evaluate if current-use pesticide exposures, lead and excess manganese alter free thyroxine (FT4), free triiodothyronine (FT3), and thyroid stimulating hormone (TSH) concentrations in pregnant women from the Infants' Environmental Health Study (ISA). Methods: At enrollment, we de
Allogeneic hematopoietic cell transplantation (allo-HCT) is an effective immunotherapeutic approach for various hematologic and immunologic ailments. Despite the beneficial impact of allo-HCT, its adverse effects cause severe health concerns. After transplantation, recognition of host cells as foreign entities by donor T cells induces graft-vs.-host disease (GVHD). Activation, proliferation and tr
This paper gives an overview of some feedback & control systems at Synchrotron SOLEIL that are in use or in development today. Beam stability is crucial and adressed in all SOLEIL aspects; Fast Orbit Feedback is a multi-input multi-output control system made to stabilize beam position perturbations in the low- & high frequency band. In addition, active RF cavities are used to maintain stab
The Multi-Blade is a boron-10-based gaseous detector developed for neutron reflectometry instruments at the European Spallation Source in Sweden. The main challenges for neutron reflectometry detectors are the instantaneous counting rate and spatial resolution. The Multi-Blade has been tested on the CRISP reflectometer at the ISIS Neutron and Muon Source in the UK. A campaign of scientific measure
Background: Atopic eczema (also known as eczema) is a chronic, inflammatory skin condition that often afflicts patients’ health and well-being. The Harmonising Outcome Measures for Eczema (HOME) initiative recommends that ‘long-term control of eczema’ is measured in all clinical trials 3 months or longer in duration. However, little has been published on what eczema control means to those living w
BACKGROUND: Oesophageal perforation is a rare but life-threatening condition with a significant morbidity and mortality. In this retrospective, nationwide study, the results of oesophageal perforation are reported for a well defined cohort, with special emphasis on the incidence, aetiology and results of surgical treatment.MATERIAL AND METHODS: 29 consecutive patients (16 males) were diagnosed wit
The nuclear stellar disc (NSD) is a flattened high-density stellar structure that dominates the gravitational field of the Milky Way at Galactocentric radius $30\, {\rm pc}\lesssim R\lesssim 300\, {\rm pc}$. We construct axisymmetric self-consistent equilibrium dynamical models of the NSD in which the distribution function is an analytic function of the action variables. We fit the models to the n
