The physical properties of polycrystalline materials depend on their microstructure, which is the nano- to centimeter scale arrangement of phases and defects in their interior. Such microstructure depends on the shape, crystallographic phase and orientation, and interfacing of the grains constituting the material. This article presents a new non-destructive 3D technique to study centimeter-sized b

The unified knowledge on power converter design and manufacturing technology establishes a powerful tool, where the cost and topology realization can be analyzed simultaneously. This paper collects the design practice and cost estimation of various components in a power electronics converter and unites that to a choice of the assembling and manufacturing processes and resulting cost of the complet

The spectrum argument purports to show that the better-than relation is not transitive, and consequently that orthodox value theory is built on dubious foundations. The argument works by constructing a sequence of increasingly less painful but more drawn-out experiences, such that each experience in the spectrum is worse than the previous one, yet the final experience is better than the experience

Eco-labelled seafood is an important tool to promote sustainable development in fisheries. A price premium on eco-labelled seafood signals a return on investment in sustainable fishing methods, providing an incentive for fishers to adopt such methods. This paper investigates whether Swedish fishermen gained a price premium from participating in the Marine Stewardship Council (MSC)-certified Swedis

Disability insurance (DI) beneficiaries lose part or all of their benefits if earnings exceed certain thresholds (“cash-cliffs”). This implicit taxation is considered the prime reason for the low number of beneficiaries who expand work and reduce benefit receipt. We analyse a conditional cash programme that incentivises work related reductions of disability benefits in Switzerland. Four thousand D

The dependency of the atmospheric boundary layer (ABL) characteristics on the ABL's height is investigated by using large eddy simulations (LES). The impacts of ABL's height on the wind turbine (WT) power production are also investigated by simulating two subsequent wind turbines using the actuator line method (ALM). The results show that, for the same driving pressure forces and aerodynamic rough

Nationalekonomiska institutionen delar Finansinspektionens oro för hushållens höga skuldsättning och de negativa effekter dessa kan få på samhällsekonomin i framtiden. Institutionen ställer sig emellertid inte bakom förslaget om ett skärpt amorteringskrav. Hushållens växande skulder är orsakade av låga räntor Amorteringskravet är förvisso en metod för att motverka de låga räntornas effekt på skuld

Skull base tumors comprise different pathological entities, making establishment of management guidelines challenging. All trials to define the ideal outcome measurement which can be reflected on treatment and prognosis improvement, are not conclusive with a lot of methodological criticism.In this thesis, I took vestibular schwannoma (homogenous pathology, different skull base approaches, may affe

A metric analysis on hulled barley grain from the Iron Age regional centre of Uppåkra and surrounding sites in southern Sweden has identified a variation in the size of the grain found on these archaeological sites. Large, high-quality grain was found more frequently at Uppåkra when compared to sites in the surrounding area, where smaller grain was more frequent. The observed large grain found at

Advanced Parkinson's disease (APD) is characterized by increased functional disability, caused by motor complications, the presence of axial symptoms, and emergent disease- and drug-related non-motor symptoms. One of the advanced therapies available is intrajejunal infusion of levodopa/carbidopa intestinal gel (LCIG); however, patient selection for this treatment is sometimes difficult, particular

Differentiated cells can be reprogrammed through the formation of heterokaryons and hybrid cells when fused with embryonic stem (ES) cells. Here, we provide evidence that conversion of human B-lymphocytes towards a multipotent state is initiated much more rapidly than previously thought, occurring in transient heterokaryons before nuclear fusion and cell division. Interestingly, reprogramming of h

We can trace the beginnings of our knowledge of early Upper Paleolithic (Aurignacian) use of fire to the pioneering 1910–1911 excavations at Abri Blanchard undertaken by Louis Didon and Marcel Castanet. At Blanchard, the excavators recognized and described fire structures that correspond in many ways to features excavated more recently in Western and Central Europe. Here, we address the issue of h

The Just-in-Time production system, or lean production system, tries to achieve a continuous flow of production, thereby reducing the inventories of materials, works-in- process and finished products. As a result only minimum levels of inventories exist in the various layers of the supply chain. Under this situation, the major earthquake followed by the tsunami on March 11, 2011 in Eastern Japan,

In the present study, neuronal and Schwann cell marker proteins were used to biochemically characterize the spatiotemporal progress of degeneration/regeneration in the silicone chamber model for nerve regeneration. Rat sciatic nerves were transected and the proximal and distal stumps were inserted into a bridging silicone chamber with a 10-mm interstump gap. Using dot immunobinding assays, S-100 p
