When conducting laser based diagnostics in combustion environments it is often desirable to obtain temporally resolved information. This can be due to several factors such as combustion taking place in a turbulent flow field, flame propagation from a spark plug in an initially quiescent combustible mixture, or rapid, multi-point fuel consumption in a homogeneous charge as a result of compression i

The aim of this study was to evaluate the effects of one year of systematic clinical supervision, and supervised individually planned care on the mood and general behavior of patients with dementia in relation to their cognitive function and level of confusion. The intervention was carried out in a ward devoted to the care of patients with severe dementia (EW), with a similar ward (CW) where no ch

Species undergoing ontogenetic diet shifts face a risk of resource competition that delays transitions between feeding stages. Such ontogenetic bottlenecks are common in piscivorous fish because competition with future prey may retard growth and prevent a size advantage. In pikeperch (Stizostedion lucioperca), year class strength of 0+ cohorts is highly variable and positively related to early ons

Many birds feed on submerged macrophytes during a temporally discrete period every year, for instance during migratory stopover or at the wintering grounds. Hence, seasonal herbivory is a common feature of the life cycle in many aquatic macrophytes. We are interested in the effect of Bewick's swans (Cygnus columbianus bewickii) feeding on the tubers of fennel pondweed (Potamogeton pectinatus) in t

Virtual reality (VR) has provoked enormous interest in the medical community. In particular, VIR offers therapists new approaches for improving rehabilitation effects. However, most of these VR assistant toots are not very portable, extensible or economical. Due to the vast amount of 3D data, they are not suitable for Internet transfer. Furthermore, in order to run these VR systems smoothly, speci

A high through-put miniaturised separation-quantification method for the heterocyclic aromatic amine 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) in urine was developed. The limit of detection was of 0.65 fmol (0.14 pg) injected or 65 pM. Heterocyclic aromatic amines are mutagenic and carcinogenic compounds formed at low levels in protein-rich food during cooking. Due to the low concentr

1. The time course and kinetics of force development following activation by opening of L-type Ca2+ channels was investigated using photodestruction of the Ca2+ channel blocker nifedipine in smooth muscle from the guinea-pig taenia coli. 2. In muscles activated using high K+ and Ca2+ and subsequently inhibited with nifedipine, photodestruction of the drug using a strong ultraviolet light flash ini

Popular Abstract in Swedish Fasoxidbränsleceller (eng. SOFC) är en keramisk bränslecellstyp som arbetar vid höga temperaturer. Genom att utnyttja energin hos avgaserna från en SOFC i en annan kraftvärmeprocess kan man erhålla ett s.k. hybridsystem som når höga verkningsgrader. Ett koncept som studerats i denna avhandling är en SOFC i kombination med en gasturbincykel (SOFC/GT). Eftersom bränslecelSolid oxide fuel cells (SOFCs) are a ceramic type of fuel cell operating at elevated temperatures. By utilising the thermal energy from the SOFC in a heat engine, a hybrid cycle with high performance can be achieved. One promising concept is a pressurised SOFC in combination with a recuperated gas turbine cycle. The fuel cell, being the more efficient power generator of the two, represents the maj

Objective: To investigate prolactin levels and related side effects in 128 men and 90 women initially treated with risperidone. Method: Patients initially treated with risperidone were followed over 5 years, during which 45% were switched to other antipsychotic drugs. Results: Initially, prolactin levels were fivefold the norm in women, and threefold in men. Diagnosis did not affect the prolactin

Transplantation of cells and tissues to the mammalian brain and CNS has revived the interest in the immunological status of brain and its response to grafted tissue. The previously held view that the brain was an absolute "immunologically privileged site" allowing indefinite survival without rejection of grafts of cells has proven to be wrong. Thus, the brain should be regarded as a site where imm

Benzimidazole units have been grafted onto a polysulfone (PSU) backbone via long alkyl thio–ether chains using a two-step procedure. In the first step, lithiated PSU was reacted with 10-undecenoyl chloride to graft PSU with undecenoyl side chains. The second step involved a free-radical thiol–ene coupling reaction between the C=C bonds of the pendant undecenoyl chains and 2-(2-benzimidazolyl)ethan

Background: Non-concordance with medication remains a major public health problem that imposes a considerable financial burden on the health care system, and there is still a need for studies on correlates of non-concordance. Our first aim is to analyse whether any of the individual characteristics age, educational level, financial strain, self-rated health, social participation, and trust in the
