The marine environment harbors a large proportion of the total biodiversity on this planet, including the majority of the earths’ different phyla and classes. Studying the genomes of marine organisms can bring interesting insights into genome evolution. Today, almost all marine organismal groups are understudied with respect to their genomes. One potential reason is that extraction of high-quality
Objectives: To evaluate the feasibility in a pilot study of in vitro endothelialisation of PTFE grafts used as interposition arteriovenous fistulas in uraemic patients. Methods: Autologous saphenous vein endothelial cells were harvested and cultured on PTFE grafts in seven patients undergoing maintenance haemodialysis. The patients had several previous failures of vascular access sites. The patien
Introduction Anal fistula is an abnormal tract with an external and internal opening that cause leakage, discomfort, and occasionally pain. Surgery is standard treatment, but recurrence and anal incontinence is common. The objective of the study was to analyze resource use, costs and sick leave for newly diagnosed patients with anal fistula in Sweden. Methods The study was based on register data f
Objective To compare the Danish Emergency Process Triage (DEPT) with a quick clinical assessment (Eyeball triage) as predictors of short-term mortality in patients in the emergency department (ED).Methods The investigation was designed as a prospective cohort study conducted at North Zealand University Hospital. All patient visits to the ED from September 2013 to December 2013 except minor injurie
In this work, laser-based diagnostic techniques were developed and applied to investigate soot formation in small-scale laboratory burners as well as in practical combustion devices. Quantitative 2D laser-induced incandescence (LII) measurements often use a cylindrical lens to shape the beam and illuminate the planar region of interest. The varying laser fluence and sheet width in the imaged flame
This thesis proposes approaches and models to increase the energy saving of the User Equipment (UE) in Long-Term Evolution (LTE) and 5G. The focus is mainly on Discontinuous Reception (DRX), the UE energy saving mechanism that was first introduced in LTE and will play an important role in 5G too.In this thesis, we take two main approaches. The first approach is based on joint optimization of DRX a
We report on a calculation of ε′K/εK at next-to-leading in the 1/Nc expansion and to lowest order in Chiral Perturbation Theory. We discuss the short-distance matching, the scale and scheme dependence as well as the long-distance short-distance matching. We include the two known chiral corrections to our result and discuss further order p4 corrections to it.
Numerical evidence for a nonvanishing 0++ glueball mass in three-dimensional SU(2) is presented. By using a long-distance correlation Monte Carlo method we obtain m0++ = (4.7±1.2)√σ in the β-range 4.0-6.5. The measurements are consistent with 1/β-scaling. The relevance of this result for SU(2) in four dimensions at finite temperature is briefly discussed.
A sensitive and fast method for hydrogen analysis has been developed. The method is based on a technique where a proton beam of a few MeV impinges on the target and the elastically scattered proton and the recoiling target hydrogen nucleus are detected in coincidence. The method makes use of the difference in time of flight and requires no energy determination. The system consists of two thin, lar
There is a scarcity of instruments for assessing opportunities for residentswith psychiatric disabilities to engage in meaningful home-based activities.We thus developed the Perceived Meaning of Activity in Housing (PMA-H),containing four subscales (activity opportunities, social interaction, developingas a person, and organization and planning). The aim of the study was to investigate the content
We study the conditions required to make the two-Higgs-doublet-model (2HDM) scalar potential stable up to the Planck scale. The lightest CP-even scalar is assumed to have been found at the LHC and the alignment limit is imposed in view of the LHC Higgs data. We find that ensuring stability up to scales 1010GeV necessitates the introduction of a soft breaking parameter in the theory. Even then, som
The ice giants Uranus and Neptune are the least understood class of planets in our solar system but the most frequently observed type of exoplanets. Presumed to have a small rocky core, a deep interior comprising ∼70% heavy elements surrounded by a more dilute outer envelope of H 2 and He, Uranus and Neptune are
With the promise of increased responsiveness and robustness of the emerging 5G technology, it is suddenly becoming feasible to deploy latency-sensitive control systems over the cloud via a mobile network. Even though 5G is herald to give lower latency and jitter than current mobile networks, the effect of the delay would still be non-negligible for certain applications.In this paper we explore and
The adipocyte hormone leptin regulates body weight in mice by decreasing food intake and increasing energy expenditure. Whether leptin is of physiological importance for these processes in humans is, however, not clear. We therefore studied the relation between leptin and habitual food intake in 64 healthy postmenopausal women. Dietary habits were assessed with a modified diet history method. Body
A potentiometric enzyme electrode is described for monitoring reactions in organic solvents. By use of an enzyme deposited on magnetic particles which are attracted to the tip of the electrode by means of a magnetic field, it is possible to produce an electrode in which the enzyme can easily be exchanged. As an example, studies of the chymotrypsin-catalyzed ester synthesis in diisopropyl ether and
A new aid to perimetric analysis, the Glaucoma Hemifield Test, primarily evaluates up-down differences in automated static visual field tests. We analyzed the visual fields of 163 eyes of 163 normal subjects and 77 eyes of 77 patients with glaucoma diagnosed on bases other than perimetry using the Glaucoma Hemifield Test and a similar, previously developed, hemifield analysis method. The performan
Resultatet av studien visar att det finns komparativa skillnader på tre olika nivåer. (1) På den nationella nivån framhålls den för arbetstagaren extensiva svenska arbetsrätten och den generösa sjukförsäkringen som potentiella orsaker till att sjukfrånvaron är högre i Sverige än i Danmark. (2) På den organisatoriska nivån konkluderas att de svenska organisationerna har starkare tonvikt på hälsa oc
The high-temperature oxidation of stainless-steel parts poses significant problems in power generation, chemical processing, and heat exchanger industries. Stainless steel grades such as austenitic AISI 316L, 310S, and ferritic 430 commonly used in industries undergo carving of oxide scales which diminishes spatial quality, increases corrosion, and reduces thermal conductivity. This thesis focuses
