Objective. To compare the effect of intraarticular injections of hyaluronan and placebo (vehicle, saline) in patients with knee pain on exertion and with joint cartilage abnormalities. Methods. Fifty-two patients with arthroscopically verified deep cartilage fissures and villus-like flakes in the symptomatic knee were randomly assigned to receive intraarticular injections of 2.5 ml of either hyalu
This study uses a discontinuity in the Swedish tertiary eligibility requirement to estimate the probability of enrolling in tertiary education, and the payoff thereof. Regression discontinuity results, show that achieving tertiary eligibility in upper-secondary education, increases the probability of enrolling in tertiary education by around 10–15 and 7 percentage points for students who enrolled
This paper presents a preliminary method developed for improved decision-support based on probabilistic methods for risk assessment using building performance simulations. The aim of the method is to support the decision-maker in all stages of the building process when deciding on the design of a building by including uncertainties and quantifying; the probability of fulfilling objectives; energy
The Zumaya section, northern Spain, is a suitable candidate to define the Global Stratotype Section and Point for the base of the Selandian Stage (Palaeocene) because of its excellent accessibility, exposure and stratigraphic continuity. Uncertainties exist, however, with regard to the stratigraphic horizon where to place the Danian/Selandian (D/S) boundary. Five potential stratigraphic horizons (
Det civilprocessuella regelverket ska slita tvister mellan enskilda rättssubjekt. Härvid ska regelverket erbjuda enskilda en möjlighet att realisera sitt rättsanspråk och därigenom erhålla rättsskydd. För att kunna göra detta ska regelverket se till att processen genomförs på ett säkert, snabbt och billigt vis. Detta kan också uttryckas som att vissa krav på rättssäkerhet och processekonomi ställsThe procedural rules within civil law are supposed to resolve disputes between individual legal entities. To this effect the rules are supposed to offer individuals a possibility to realize their legal claims and thereby receive legal protection. In order to do this the procedural rules need to ensure that civil law cases are conducted in a reliable, quick and inexpensive manner. Another way to ex
Since the collapse of the Bretton Woods system, the system of fixed exchange rates amongst principal industrial countries, in the early 1970s, a new era began, introducing the floating exchange rate regime. Since the inception of the floating rate regime, the general interest in forecasting exchange rate movements has grown considerably. Yet, forecasting the exchange rate is extremely difficult, a
Personlig varumärkning är ett koncept som innebär att varumärken och dess image till stor del identifieras med en person. Personliga varumärken kommer med stora fördelar, exempelvis att en djupare relation etableras mellan organisation och konsument, vilket kan vara svårt att uppnå för en mer opersonlig organisation. Däremot kommer det även med större risker, som att organisationen och personen ba
Around the world, the treatment of food waste is a major administrative and environmental problem throughout the food supply chain. Beijing, as any other mega city, is facing vast issues of sustainable food waste treatment in addition to efforts for food waste reduction. Presently the majority of Beijing's food waste is treated together with the mixed residual waste in landfills (53%) and inci
The production cross-section of a top quark in association with a W boson is measured using proton–proton collisions at s√=8TeV. The dataset corresponds to an integrated luminosity of 20.2fb−1, and was collected in 2012 by the ATLAS detector at the Large Hadron Collider at CERN. The analysis is performed in the single-lepton channel. Events are selected by requiring one isolated lepton (electron o
Current research on enzyme based electrochemical biosensors deals essentially with the same target analytes as was at focus in the early days of biosensor research, that is those within the clinical/medical, food/agriculture, and environmental fields [1•–13]. However, there has been substantial progress through the years and progress continues, as resumed in Figure 1A. One of the major differences
In this study we tried to explore available usability criterions. We wanted to see if they can be used for mobile phone. In order to investigate the usability of mobile phones we looked closer at both literature in the HCI field and also conducted interviews with the usability expert, user tests and surveys with mobile phones end users. During our research we noticed that designers need to take co
Alkyl glycosides were synthesised from starch and alcohols using Aspergillus oryzae a-amylase as catalyst. In the degradation of starch by a-amylase, the alcohols competed with water as glycosyl acceptors. In the reaction with methanol, methyl maltoside and methyl maltotrioside were the main alcoholysis products. Conversion of 45 g/1 starch in 30% methanol resulted in a product mixture containing
