Since the working environment act was passed in 1991 employers in Sweden are to plan and control the working environment conditions in workplaces. They are responsible for organized rehabilitation at the workplace including the development of rehabilitation plans and a plan for interventions in order for a sick-listed client to be able to return to work.The aim of this study was to describe employ
Summary. The reasons that inhibitory factor VIII antibodies develop in only a fraction of patients with haemophilia A remain unclear, but studies of genetically related subjects have indicated that the immunological outcome of replacement therapy is to a large extent determined by patient-related risk factors. Non-genetic factors will also influence the inhibitor risk, since events challenging the
The minimum edge dominating set (MEDS) is one of the fundamental covering problems in graph theory, which finds many practical applications in diverse domains. In this paper, we propose a meta-heuristic approach based on genetic algorithm and local search to solve the MEDS problem. Therefore, the proposed method is considered as a memetic search algorithm which is called Memetic Algorithm for mini
All languages borrow words from other languages. Some languages are more prone to borrowing, while others borrow less, and different domains of the vocabulary are unequally susceptible to borrowing. Languages typically borrow words when a new concept is introduced, but languages may also borrow a new word for an already existing concept. Linguists describe two causalities for borrowing: need, i.e.
The sFLASH project at DESY is an experiment to study direct seeding using a source based on the high-harmonic generation (HHG) process. In contrast to SASE, a seeded FEL exhibits greatly improved longitudinal coherence and higher shot-to-shot stability (both spectral and energetic). In addition, the output of the seeded FEL is intrinsically synchronized to the HHG drive laser, thus enabling pump-p
In this chapter, speech enhancement and echo cancellation for hands-free mobile telephony are discussed. A number of microphone array methods have been tested and results from car measurements are given. Traditional methods such as linearly constrained beamforming and generalized sidelobe cancelers are discussed as well as array gain optimization methods. An in situ calibrated method which gives a
Spectral properties of the weighted Laplace operator in the presence of fractal boundaries are numerically investigated for both Neumann and Dirichlet boundary conditions. This corresponds to the characterization of heat and mass transport in microchannels with irregular and rough surfaces induced by the microfabrication process. The axial velocity field with no-slip boundary conditions, represent
This work presents a digital calibration technique in continuous-time (CT) delta-sigma (Δ Σ) analog to digital converter. The converter is clocked at 144 MHz with a low oversampling ratio (OSR) of only 8. Dynamic element matching is not efficient to linearize the digital to analog converter (DAC) when the OSR is very low. Therefore, non-idealities in the outermost multi-bit feedback DAC are measur
Extensive diversity has been identified in the human heavy chain immunoglobulin locus, including allelic variation, gene duplication, and insertion/deletion events. Several genes have been suggested to be deleted in many haplotypes. Such findings have commonly been based on inference of the germline repertoire from data sets covering antibody heavy chain encoding transcripts. The inference process
In this work, we study the stationary structures and the breathing mode behavior of a two-dimensional self-bound binary Bose droplet. We employ an analytical approach using a variational ansatz with a super-Gaussian trial order parameter and compare it with the numerical solutions of the extended Gross-Pitaevskii equation. We find that the super-Gaussian is superior to the often used Gaussian ansa
Background: Palliative care focuses on identifying, from a holistic perspective, the needs of those experiencing problems associated with life-threatening illnesses. As older people approach the end of their lives, they can experience a complex series of problems that health-care professionals must identify and document in their patients’ records. Documentation is thus important for ensuring high-
Pancreatic cancer is known for its propensity to metastasize. Recent studies have challenged the commonly held belief that pancreatic cancer is a stepwise process, where tumor cells disseminate late in primary tumor development. Instead it has been suggested that pancreatic tumor cells may disseminate early and develop independently and in parallel to the primary tumor. Circulating tumor cells can
Background: Differences in stroke care and health outcomes between men and women are debated. The objective of this study was to explore the relationship between patients' sex and post-stroke health outcomes and received care in a Swedish setting. Methods: Patients with a registered diagnosis of acute intracerebral hemorrhage (ICH) or ischemic stroke (IS) within regional administrative systems (IC
In applications spanning from image analysis and speech recognition to energy dissipation in turbulence and time-to failure of fatigued materials, researchers and engineers want to calculate how often a stochastic observable crosses a specific level, such as zero. At first glance this problem looks simple, but it is in fact theoretically very challenging, and therefore few exact results exist. One
In 2015, LIBER commissioned the “Working group on Research and Education”. The goal was to collect best practices in library support to both education and research, in part by examining user survey data. As a first step the group started a European LibQUAL consortium, which was evaluated in 2016. As a second step, a survey sent to all 301 European LIBER university libraries asking questions pertai
Byggnadssektorn stod för 39 % av energi- och processrelaterade koldioxidutsläpp år 2018 och globala utsläpp från byggnader ökade med 2 % för det andra året i rad. Därför är det viktigt att ta fram lösningar på byggnadsdesign som minimerar klimatpåverkan från byggnader. Samtidigt som produktionen av bostäder och kommersiella byggnader måste vara kostnadseffektiv för att skapa boende och arbetsplatsThe building and construction sector accounted for 39% of energy and process-related carbon dioxide emissions in 2018 and global emissions from buildings increased by 2% for the second consecutive year. It is therefore important to find building design solutions that minimise the climate impact of buildings. At the same time, the production of residential houses and commercial buildings must be co
This paper addresses the problem of the detailed quality end-test of vacuum cleaner motors at the end of the manufacturing cycle. For the prototyping purposes a test rig has been constructed and is presented in short. The diagnostic system built hereto takes advantage of vibration, sound and commutation analysis as well as parity relation checks. The paper focuses on the sound analysis module and
P4 ATPase lipid flippases are ATP-driven transporters that translocate specific lipids from the exoplasmic to the cytosolic leaflet of biological membranes, thus establishing a lipid gradient between the two leaflets that is essential for many cellular processes. While substrate specificity, subcellular and tissue-specific expression, and physiological functions have been assigned to a number of t
