Background/Aims: Increasing evidence suggests a link between brain-derived neurotrophic factor (BDNF) and suicidal behaviour (SB). Furthermore, decreased peripheral BDNF levels have been associated with clinical symptoms in various psychiatric disorders as well as with personality dimensions in healthy individuals. However, the relationship between BDNF and psychopathology is poorly investigated r

Little is known about the hemodynamic response to exercise in heart failure patients at various ages before and after heart transplantation (HT). This information is important because postoperative hemodynamics may be a predictor of survival. To investigate the hemodynamic response to HT and exercise, we grouped our patients based on preoperative age and examined their hemodynamics at rest and dur

Popular Abstract in Swedish ”Practice variation” I den kliniska vardagen ser man ofta slående variationer i handläggningsrutiner mellan läkare och vårdcentraler utan att detta kan förklaras av skillnader i sjuklighet hos patienterna. Dessa oförklarade skillnader benämns ”practice variation” och beror på lokalt förankrade rutiner ofta etablerade sedan länge. De är sällan vetenskapligt underbyggda u

Monitoring low molecular weight heparins (LMWH's) in the perioperative period is prudent in patients at high risk of coagulative complications, especially when the patient has an epidural catheter requiring withdrawal, which is associated with the risk of spinal haematoma. The aim of this study was to evaluate the in vitro dose-responses of two different LMWH's on two different viscoelastic haemos

The impact echo (IE) method is widely used in non-destructive testing of concrete plate like structures but has proved difficult to apply on asphalt pavements. Observed low IE resonance amplitudes on asphalt have been attributed to larger material damping but the present study shows that it may also be an effect from a larger Poisson's ratio. The IE frequency corresponds to the stationary resonanc

We review Buchler and Colangelo's result that leading divergences at any loop order can be calculated using only one-loop calculations and we provide an alternative proof. We then use this method to calculate the leading divergences of and thus the leading logarithmic corrections to the meson mass in the massive $O(N)$ nonlinear sigma model to five-loop order. We also calculate the all-loop result

We extend our earlier work on the massive O(N) non-linear sigma model to other observables. We derive expressions at leading order in the large N expansion at all orders in the loop expansion for the decay constant, vacuum expectation value, meson meson scattering and the scalar and vector form factors. This is done using cactus diagram resummation using a generalized gap equation and other recurs

One option for coping with wasteful uses of fresh water in landscape irrigation is to use the treated greywater(GW). In the present study, an evaluation of a simple treatment system for reusing GW to irrigate green areas,trees, and ornamentals all over the campus in Tafila Technical University (TTU), Jordan, is presented. After 12 months of using the treatment system, the necessity for using fresh

Syftet med uppsatsen är att med hjälp av historiska data från perioden december 1996 – december 2010 testa en portföljvalsmodell kallad The Permanent Portfolio (TPP) på den svenska marknaden. Modellen går ut på att placera tillgängligt kapital i fyra lika stora delar över fyra olika tillgångsslag. Dessa fyra tillgångslag är aktier, statsobligationer, guld och kontanter. I uppsatsen gestaltas dessa

I ett samhälle med ökad globalisering blir regler angående den internationella privat- och processrätten allt viktigare. Denna uppsats behandlar lagvalsregler, vilka går att finna i Romkonventionen. Romkonventionens huvudregel är lagvalsfrihet. Det finns dock bestämmelser i konventionen som inskränker denna möjlighet. Artikel 7 rörande internationellt tvingande regler är ett exempel på detta och ä

This report contains a description of the fire safety situation of Holmagården, which is a residence for elderly with special needs, in Svedala, Sweden. The purpose is to evaluate the personal safety in case of fire where concern has taken to the health status of the individuals at Holmagården. Three different fire scenarios have been the starting direction for modelling and calculating. To estima
