The ability to reproduce a specified head-on-trunk position can be an indirect test of cervical proprioception. This ability is affected in subjects with neck pain, but it is unclear whether and how much pain or continuous muscle contraction factors contribute to this effect. We studied the influence of a static unilateral neck muscle contraction task (5 min of lateral flexion at 30% of maximal vo

CO oxidation over Pd(100) and Pd75Ag25(100) has been investigated by a combination of near-ambient-pressure X-ray photoelectron spectroscopy, quadrupole mass spectrometry, density functional theory calculations, and microkinetic modeling. For both surfaces, hysteresis is observed in the CO2 formation during the heating and cooling cycles. Whereas normal hysteresis with light-off temperature higher

It is well established that high ambient heat could cause congenital abnormalities resulting in miscarriage or stillbirth among certain species of mammals. However, this has not been systematically studied in real field settings among humans, despite the potential value of such knowledge for estimating the impact of global warming on the human species. This study sought to test the hypothesis that

Medical students’ access to clinical supervision when rotating through hospital workplaces and the quality of that supervision are and have been an area of growing professional and societal concern. Increased training measures targeted at supervising physicians have been suggested to address this issue. Traditionally, such training has focused on offering physicians opportunities to develop as sup

The aim of the Massive Open Online Course (MOOC) ‘Work and Technology on Human Terms’ was to be a modern, highly accessible study material in Ergonomics/Work science to contribute to safer and healthier workplaces. The course targets engineering students, but also students in economics, human relations, physiotherapy, occupational health, as well as professionals. The purpose of this paper is to d

Cancer är den näst vanligaste dödsorsaken i världen idag och en tredjedel av Sveriges befolkning blir diagnosticerade med cancer under sin livstid. Av alla cancerfall i Sverige, så är prostatacancer den vanligaste och bröstcancer den näst vanligaste, medan hos enbart kvinnor så är bröstcancer den vanligaste med 29,2 % av cancerfallen. Överlevnaden efter en cancerdiagnos har i Sverige ökat sedan 70Cells are commonly used in research to evaluate toxicity and efficiency of drugs. However, to further increase the usefulness of cells as well as the understandings of effects of different interventions, new methods must constantly be developed and refined. Today, many assays use end-point analysis of large populations of cells, to evaluate the research question. However, there are many cases when

BACKGROUND: Critically ill newborn infants undergo a variety of painful procedures or experience a variety of painful conditions during their early life in the neonatal unit. In the critically ill paediatric and neonatal population, clonidine is prescribed as an adjunct to opioids or benzodiazepines aiming to reduce the doses of these drugs that are required for analgesia or sedation, or to facili

Glacier retreat caused by global warming alters the hydrological regime and poses far-reaching challenges to water resources and nature conservation of the headwater of Yangtze River, and its vast downstream regions with dense population. However, there is still lack of a robust modeling framework of the “climate-glacier-streamflow” in this water tower region, to project the future changes of glac

The lengths of fallows have decreased in many parts of the Sahel due to agricultural expansion, which can have negative impacts on crop production when few other ways to improve soil fertility exist. However, the dynamics of agricultural expansion may change because of the changing role of agriculture in society due to increased livelihood diversification outside of agriculture. The results of thi

Aim: To investigate patterns of somatic inpatient ICD-10 diagnoses in people with intellectual disabilities (ID) 55 years and older in relation to age over an 11-year period, and to compare these patterns with a general population sample. Method: The study was based on Swedish national registers. The ID group (n=7936) comprised people who were aged 55 or above in 2012. They were age- and sexmatche

Membrane technology, i.e., ultrafiltration and nanofiltration, is growing in popularity, as it is a space efficient alternative for surface water treatment. Two types of hollow fiber membranes were tested in a fully equipped and automated pilot at a Swedish water treatment plant. Raw water was treated by a nanofilter and by coagulation before an ultrafilter. Operation parameters recorded during th

A methodology for studying change processes in working life combining computer-aided planning and cooperation in project groups is evaluated. The methodology is applied and studied in a planning workshop with representatives from manufacturing industries—managers, production engineers, supervisors as well as shop floor workers—and from health-and-safety agencies utilizing the methodology for plann

Ambient fine particulate matter PM2.5 (particles with a diameter smaller than 2.5 μm) has been associated with cardiovascular and respiratory morbidity and mortality. It has been shown that biomass burning for heat production purposes can generate large amounts of fine particles. Thus characteristics of particle emissions from biofuel combustion may be important in the assessment of health effects

Popular Abstract in Swedish I denna avhandling studeras ledningsförmågan hos nanometer-stora kvantprickar tillverkade i halvledarmaterial. Halvledare är material vars ledningsförmåga ligger någonstans mellan ledare (metaller) och isolatorer. I halvledare kan ledningsförmågan ändras med elektriska fält, vilket har möjliggjort utvecklandet av halvledartransistorn. Utvecklandet av halvledartransistorThis thesis focuses on electron transport in single and double quantum dots defined in low-dimensional, narrow-band-gap III-V semiconductor materials. Fabrication schemes are presented for defining single and double quantum dots in lateral InGaAs/InP heterostructures, either by a combination of etching and local gating or solely by local top gating. The quantum dots are here electrostatically conf

Bone marrow transplantation (BMT) is a conceptual and elegant example of stem cell therapy, rendered possible by the dual capacity of hematopoietic stem cells (HSCs) to self-renew and differentiate. These defining features ultimately ensure the production of all blood cell lineages and simultaneous maintenance of the stem cell pool, thereby maintaining lifelong homeostasis.
