A key feature of economic institutions is that they facilitate commercial transactions by reducing uncertainty and risk in markets. When trust and trustworthiness stem from confidence in community sanctions of norms, principal and agent relations are enforceable without resorting to legal rule

Summary. We assessed the reliability and construct validity of the Compatible MRI scale for evaluation of elbows, and compared the diagnostic performance of MRI and radiographs for assessment of these joints. Twenty-nine MR examinations of elbows from 27 boys with haemophilia A and B [age range, 5–17 years (mean, 11.5)] were independently read by four blinded radiologists on two occasions. Three c

Let us have an NLFSR with the feedback function g(x) and an LFSR with the generating polynomial f(x). The function g(x) is a Boolean function on the state of the NLFSR and the LFSR, at any time instance t. Whenever the LFSR has good statistical properties, it is used for controlling the randomness of the NLFSR's state machine. In this paper we define and study the general class of "Grain" family o

Popular Abstract in Swedish I min avhandling har jag sökt den kinesiska barnbokens litterära rötter.

In a placebo-controlled randomised single-blind long-term study with independent observer of chronic nociceptive low back pain, n=50, it was found

Popular Abstract in Swedish Venös trombossjukdom (blodpropp i ben och lunga) förekommer i en frekvens av ca 160 per 100.000 invånare och år i Malmö. Venös trombossjukdom är en av våra vanligaste sjukdomar. Bakgrunden till venös trombossjukdom är mångfacetterad och både ärftliga och förvärvade riskfaktorer bidrar till sjukdomen. Kända riskfaktorer är övervikt, immobilisering (ex gipsbehandling, slaActivated protein C resistance (APC resistance) is the most common hereditary condition associated with venous thrombosis. The syndrome known as APC resistance is perfectly linked to a mutation in the gene coding coagulation FV (FV:Q506) mutation changing Arg 506 to Gln in the APC cleavage site. APC-resistance is associated with a hypercoagulable state and life-long increased risk of thrombosis. A
