The interaction between large hydrophobic and hydrophilic surfaces in aqueous solution is investigated, using Metropolis Monte Carlo simulations and density functional theory. Special attention is devoted to the solvation force and its dependence on the nature of the solvent-solvent and solvent-surface interactions. In order to facilitate simulations of surface forces in aqueous systems, methods
This paper proposes a method for multi-loop PI controller design which can achieve dominant pole placement for two input two output processes. It is an extension of the original dominant pole design (PID Controllers: Theory, Design, and Tuning, Instrument Society of America, Research Triangle park, NC, 1995.) for SISO systems. Unlike its SISO counterpart, where the controller parameters can be obt
Objective The effect of salt restriction on blood pressure is under intense debate. We tested the effect of 100 mmol salt reduction on ambulatory blood pressure (ABP) in 46 Swedish individuals, 39 of whom completed the study, using a double-blind, placebo-controlled, crossover design. Furthermore, we tested whether the basal plasma concentration of renin or N-terminal atrial natriuretic peptide (N
Objectives: At the request of the European Commission and in the framework of the European Machinery Directive, research was performed in five different laboratories to develop specifications for surface temperature limit values for the short-term accidental touching of the fingertip with cold surfaces. Methods: Data were collected in four laboratories with a total of 20 males and 20 females perfo
The molecular self-diffusion in concentrated aqueous mixtures based on an oppositely charged po ymer-surfactant pair has been investigated by NMR pulsed field gradient techniques. The investigated structures were an ordered cubic Pm3n phase (ca. 50 wt % water) and a disordered micellar phase, both containing cetyltrimethylammonium (CTA(+)) micelles with mixed acetate (Ac-) and polyacrylate (PA(-))
By collecting distances from the literature, a set of 73 planetarynebulae with mean distances of high accuracy is derived. This sample isused for recalibration of the mass-radius relationship, used by manystatistical distance methods. An attempt to correct for a statisticalpeculiarity, where errors in the distances influences the mass-radiusrelationship by increasing its slope, has been made for t
Popular Abstract in Swedish Osteoporos (benskörhet) innebär att såväl bentätheten som skelettets hållfasthet minskar, vilket leder till ökad risk att få frakturer (benbrott). Osteoporos är en folksjukdom, där frakturerna medför stora kostnader såväl för individen som för samhället. De frakturer som räknas som osteoporosfrakturer är i första hand de som drabbar höft, bäcken, axel, handled och kota.Hip fracture is the most severe clinical manifestation of bone fragility. Hip fracture predominantly affects an already frail population and is associated with multi-cause morbidity and high mortality. Improved knowledge of long-term outcome is essential in order to improve future care and prevention of both fracture and its complications. In this thesis, all hip fracture patients during 1984-198
Objective. Anterior cruciate ligament (ACL) rupture involves an increased risk of osteoarthritis. The purpose of this study was to explore changes in cartilage thickness over 5 years after ACL rupture. Methods. A total of 121 young active adults (ages 18-35 years; 26% women) from the Knee ACL, Nonsurgical versus Surgical Treatment (KANON) study, who had acute traumatic rupture of the ACL were stud
Research has shown that families experience poor involvement in needs assessment of older people while little is known about municipal care managers' views of family participation. The aim was to explore how municipal care managers view families' participation in and influence on needs assessment of older people receiving public home help. Individual interviews (n = 26) were conducted with care ma
Bed material agglomeration was studied experimentally in a fluidized-bed biomass combustor, Four biomass fuels, four bed materials, three bed additives, and three NOx additives were tested in a temperature range of 670-870 degreesC and at two pressure levels of 1.0 and 1.5 MPa. Two types of agglomeration were observed, a homogeneous and a heterogeneous type. The first occurred at low temperature a
Popular Abstract in Swedish Mycken möda har under de senaste årtiondena lagts ner på forskning om försurande utsläpp och dess skadliga effekter på skogar, vattendrag och människor. Kritiska belastningsgränser, i folkmun kallat "vad naturen tål", har tagits fram och använts i europeiska förhandlingar om utsläppbegränsningar. För skogsekosystem baseras de kritiska belastningsgränserna för försurandeAcidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.g. for Swede
BACKGROUND: The transport of large proteins across the glomerular capillary wall (GCW) may increase several fold in glomerular diseases. The occurrence of IgM in urine is a consequence of the presence of large defects or shunts in the GCW, whereas albuminuria is probably a result of an altered charge- and size-selectivity of the GCW. In order to examine whether patho-morphological differences infl
The most important issue in this dissertation will be a discussion concerning metal age flint use in Scania. Since flint tools from the Bronze and Iron Ages and Medieval times have rarely been examined, there are few general guidelines in typology or morphology. It is quite clear that conversions of existing Stone Age typological schemes are unsuitable when one intends to study the often simple an
Individuals with a dismissing-avoidant pattern of attachment are assumed to repress anxiety-related signals, a disposition hypothesized to interfere with facial mimicry and emotional contagion. Further, they are assumed to have one internal working model associated with anxiety, operating out of awareness at early, automatic stages of information processing, and another positive model operating at
A farm systems mass-balance calculation model, FARMFLOW, was applied to a case study comparing organic and conventional management of a Swedish experimental dairy farm, Ojebyn. Parameterisation of the model is implemented using detailed field data from the Ojebyn farm where the two management systems have been run parallel for more than 11 years. Simulations were made to compare the stocks, flows
An integrated process for purifying a 6.1 kilo base pair (kbp) plasmid from a clarified Escherichia coli cell lysate based on an ultra/diafiltration step combined with polymer/polymer aqueous two-phase system and a new type of chromatography is described. The process starts with a volume reduction (ultrafiltration) and buffer exchange (diafiltration) of the clarified lysate using a hollow fibre me
Smooth muscle cell (SMC)-specific deletion of transforming growth factor beta (TGF-beta) signaling would help elucidate the mechanisms through which TGF-beta signaling contributes to vascular development and disease. We attempted to generate mice with SMC-specific deletion of TGF-beta signaling by mating mice with a conditional ("floxed") allele for the type 11 TGF-beta receptor (tgfbr2(flox)) to
The objective of this paper is to provide a general account of value relations. But it takes its departure is a special type of value relation, parity. The notion of parity is due to Ruth Chang. According to her, two items may be evaluatively comparable even when neither is better than, worse than, or equally good as the other. There is a fourth kind of comparability: being on a par. Recently, Jos
