Eutrophication of the Baltic Sea has in Sweden led to the initiation of government schemes aiming to increase wetland areas in agricultural regions and thereby reduce nutrient transport to the sea. Landowners play a significant role as providers of this ecosystem service and are currently offered subsidies to cover their costs for constructing and maintaining wetlands. We undertook a grounded theo
A search for squarks in R-parity violating super-symmetry is performed in e(+/-)p collisions at HERA using the H1 detector. The full data sample taken at a centre-of-mass energy root s = 319 GeV is used for the analysis, corresponding to an integrated luminosity of 255 pb(-1) of e(+)p and 183 pb(-1) of e(-)p collision data. The resonant production of squarks via a Yukawa coupling. lambda' is consi
This thesis aims to evaluate the situation for cyclists in Stellenbosch, one of the leading cities in South Africa when it comes to planning for cyclists. The current situation for cyclists in Stellenbosch will be evaluated in terms of level of service, accessibility and safety. Moreover, the purpose of this study is also to investigate if there are there any official policies or plans to improve
Parallel trade in the pharmaceutical industry is a complicated issue because it has connections with competition law, trade law, and intellectual property law. International exhaustion benefits consumers by promoting price competition. This is an extremely attractive argument. For several years, the parallel trade in pharmaceutical products has been an important issue for the European pharmaceutic
Aim: To investigate whether there is any pharmacokinetic rationale for the common practice of administering vincristine to adolescents at relatively lower doses than those to younger children. Methods: A total of 98 children, aged 1.3-17.3 y, with acute lymphoblastic leukaemia (ALL) were studied on day I of induction therapy. Plasma samples were drawn before and 10, 30, 360 and 1380 min after inje
The muscles of the pharynx are controlled by networks of neurons under the control of specific regions in the brain stem, which have been fairly well studied. However, the transmission between these neurons and the pharyngeal muscles, at the motor end plates, is less well understood. Therefore, an in vitro model for the study of neuromuscular transmission in the pharyngeal muscle of the mouse was
OBJECTIVES:: The aim of this study is to explore the long-term quality of life (QoL) in adults after surgery for Hirschsprung disease in childhood. PATIENTS AND METHODS:: Altogether 51 patients were operated for HD at our center during the period 1969 to 1989. In 2007, the validated instruments for assessing QoL, the SF-36 health survey and the Gastrointestinal Quality of Life Index (GIQLI), were
BACKGROUND: The importance of voltage-dependent conductances in sensory information processing is well-established in insect photoreceptors. Here we present the characterization of electrical properties in photoreceptors of the cockroach (Periplaneta americana), a nocturnal insect with a visual system adapted for dim light. RESULTS: Whole-cell patch-clamped photoreceptors had high capacitances and
Organisms appear opaque largely because their outer tissue layers are strongly scattering to incident light; strongly absorbing pigments, such as blood, typically have narrow absorbances, such that the mean free path of light outside the absorbance peaks can be quite long. As people cannot see through tissue, they generally imagine that tissues like the brain, fat, and bone contain little or no li
A sport-related concussion (SRC) is caused by a force transmitted to the brain during sports, and may lead to long-term disabilities and neurodegeneration. The underlying pathophysiological mechanisms causing persistent post-concussive symptoms (PPCS) lasting beyond the normal four-week period, have not been established. The aim of this thesis was to investigate mechanisms of persistent symptoms i
What is the role of deictic gestures in expressing affective valence, and can such gestures serve as an indicator of awareness in choice making? To examine this, we analyzed participants’ deictic gestures toward preferred and non-preferred picture alternatives in an experimental choice justification task. The task involved manipulation: in some trials, participants were presented with the rejected
Background: Tuberculosis (TB) disease has been associated with pregnancy complications. However, the potential impact of TB infection (TBI) on pregnancy outcome is unknown. To investigate this, we conducted a register-based study in immigrant women screened with QuantiFERON assays for TBI in antenatal care in Sweden. Methods: Women with history of immigration from TB-endemic countries were eligibl
