Popular Abstract in Swedish Denna avhandling undersöker dagvatten som en resurs i svensk urban miljö. Fokus har varit öppna dagvattensystem för flödeskontroll och uppsamlingssystem för regnvatten. För att analysera realiserandet av öppna dagvattensystem, presenteras två fallstudier; Augustenborg i Malmö och Bäckaslöv våtmark i Växjö. De kvarhållande och fördröjande effekterna som uppnås med gröna This thesis investigates the beneficial use of stormwater in Swedish urban environments. The focus has been on open stormwater systems for source control, as well as rainwater collection systems. To analyse the implementation of open stormwater systems, two case studies are presented: Augustenborg in Malmö and Bäckaslöv wetland in Växjö. The retention and detention effects of green-roofs have been

An experimental study of a glow plug engine combustion process has been performed by applying chemiluminescence imaging. The major intent was to understand what kind of combustion is present in a glow plug engine and how the combustion process behaves in a small volume and at high engine speed. To achieve this, images of natural emitted light were taken and filters were applied for isolating the f

Allt sedan 1989 har vi i den södra sjukvårdsregionen gett en 20-poängskurs i grundläggande forskningsmetodik. Vår målsättning har varit att ge många läkare en basal vetenskaplig skolning till glädje för den vardagsnära kvalitetsutvecklingen och verksamhetsuppföljningen, men också att stimulera enstaka läkare till att påbörja en regelrätt forskarutbildning. Vi har genom åren presenterat utvecklingeAt the Department of Community Medicine at Lund University we have given courses in basic research methodology since 1989. The course has yielded 20 points of university credit, the equivalent of one full-time semester of studies, and it has been run part-time, covering one and a half years. Our aim has been to provide a large number of physicians with basic training in research methods, and to st

The purpose of this publication was to present and evaluate the methods for reference dosimetry in the epithermal neutron beam at the neutron capture therapy facility at Studsvik. Measurements were performed in a PMMA phantom and in air using ionization chambers and activation probes in order to calibrate the epithermal neutron beam. Appropriate beam-dependant calibration factors were determined u

A previous study showed that vibratory stimulation of neck muscles in humans induced short-latency electromyographic (EMG) activation of lower leg muscles, producing postural reactions at the feet. These findings indicated that cervical proprioception contributes to stabilization of stance through rapidly integrated pathways. However, as vibration may excite both proprioceptive and vestibular affe

Den amerikanska bidragsreformen 1996 var den mest omvälvande socialpolitiska händelsen i USA sedan 1930-talet. Ändå har det talats ganska tyst om den – i Sverige. I denna artikel diskuteras utfallet av reformen med hjälp av några nyutkomna böcker, dels Howard Kargers och David Stoesz’ stora lärobok om amerikansk socialpolitik, dels Jeffrey Groggers och Lynn Karolys ambitiösa utvärdering av utvärde

A fast spectral approximation of a narrow-band computer model is proposed for prediction of thermal radiation in a generally nonisothermal and nonhomogeneous combustion environment. The approximation is made by assuming each discretized spatial element along a line of sight to be locally "gray" within each small narrow-band spectrum interval. For each spatial element, the local equivalent spectral

5-Hydroxytryptamine has been suggested to be a mediator in peripheral cold-induced vasospasm. In order to investigate the contribution of different 5-hydroxytryptamine receptor subtypes in the contractile response during cooling, segments of subcutaneous hand veins obtained from 50 patients undergoing hand surgery were examined in vitro in organ baths. The temperature in the bath was initially 37

It is argued that the so-called fitting attitude- or buck-passing pattern of analysis may be applied to personal values too (and not only to impersonal values, which is the standard analysandum) if the analysans is fine-tuned in the following way: An object has personal value for a person a, if and only if there is reason to favour it for a’s sake (where “favor” is a place-holder for different pro

The large body of recently measured energies and electromagnetic properties of high-spin states in the Z = 40-45, N = 46-50 isotopes is consistently accommodated in the shell model using empirical and schematic two-body matrix elements in the (1g(9/2), 2p(1/2)) model space. In particular, we test the purity of seniority, the effects of an enlarged model space (including the 1f(5/2), 2p(3/2) orbits

Neurogenesis and angiogenesis are stimulated by a number of antidepressant treatments, and cellular plasticity has emerged as a phenomenon with great relevance to the etiology and treatment of depression. In paper I we characterize how ECS-induced endothelial cell proliferation leads to vascularization of the adult rat hippocampus. In the molecular layer of the hippocampus a series of 10 ECS-treat

The Bremmer series is used to reduce a complex scattering problem to a sequence of simpler single-scattering problems. In the Bremmer series, the wave equation is first decomposed into a coupled system of one-way wave equations. The system is then decoupled into a sequence of one-way wave equations with a fixed-point iteration. In this paper, a left-symbol representation of the decomposition opera

Background: Two contradictory hypotheses have been proposed to explain the relationship between allergic conditions and malignancies, the immune surveillance hypothesis and the antigenic stimulation hypothesis. The former advocates that allergic conditions may be protective against development of cancer, whereas the latter proposes an increased risk. This relationship has been studied in several c

Objective. CHEK2* 1100delC is a frame-shifting germ-line mutation which abolishes the function of cell-cycle-checkpoint kinase 2 (chk2) and hence impairs the cells' response to DNA damage. This variant occurs in approximate to 1% of the general Western population but has been reported to be more common among patients with breast and prostate cancer. The aim of this study was to investigate the sig
