Elements emitted to the atmosphere are partly exported to more remote areas and contribute to the regional and territorial deposition rates. This study is based on the principle that carpet-forming bryophytes (pleurocarpic mosses) absorb elements and particles from rain, melting snow and dry deposition. We compare the concentrations of 60 elements in carpets of the forest moss Pleurozium schreberi

Four experimental methods were used to study the phase diagram, as well as the thermodynamic and structural properties of the binary system n-octyl alpha-D-glucoside water in the temperature range 25-130degreesC. Sorption calorimetry allows one to determine the activity of water and enthalpy of mixing as functions of water content at constant temperature, while DSC scans temperature at constant co

Discussion of aesthetics within a pedagogical context

The work presented deals with the characterisation and application of critical gels. In order to provide a theoretical foundation, the thermodynamics of the reversible swelling and shrinking behaviour of such gels is outlined. The temperature-sensitive poly(N-isopropylacrylamide) gel (NiPAAm) was chosen for experimental investigation. Dif ferent methods of producing the gel are described, and the

The main concern of the paper is to address some problems that arise when defining the concept of contrast and to clarify the relation between contrast and other concepts of information structure. As to the definition of the notion of contrast, we need to separate the semantic and pragmatic aspects of contrastiveness as well as identify different types within these two main categories. There is ab

New neurons are only generated in two places of the postnatal brain; the subventricular zone (SVZ) and hippocampus. The SVZ-derived cells specifically migrate to the olfactory bulb where they give rise to new interneurons. We have genetically manipulated the postnatal SVZ progenitor cells with the aim to direct them to a neuronal fate in the striatum. Our result showed that ectopic expression of t

This study aimed to investigate the presence of pain, pain duration, localization(s), intensity, type and pharmacological treatment among older adults living in sheltered accommodation or receiving rehabilitation, as well as the agreement between pain assessments performed by staff and the older adults. Twenty-nine randomly selected older adults (65+ years) and the staff who looked after them part

BACKGROUND: Previous studies have shown that short-term treatment with adrenocorticotrophic hormone (ACTH) has a strong and rapid lipid-lowering effect. In this long-term study of nephrotic patients with idiopathic membranous nephropathy, the influence of ACTH on the serum lipoprotein profile and glomerular function as well as the dose-effect relationship was investigated. METHODS: Fourteen patien

Popular Abstract in Swedish Med föreliggande avhandling vill jag belysa att Chrétien de Troyes Graalsaga, till skilnad från vad de åtskilliga kritiker har påstått, inte bygger på traditionella ridderliga värden, men väl avslöjar en problematisk ideologi. Denna ideologi prövas med hjälp av V. Jouves metod, som beskrivs i hans Poétique des valeurs. Graalsagans värden analyseras ur ett dubbelt perspThis dissertation aims at showing that Chrétien de Troyes' Conte du Graal does not, as often affirmed, uphold traditional chivalrous values, but discloses a problematic ideology, mostly as a result of multiple interactions at the textual level. In order to examine ideology, Le Conte du Graal is analysed in the light of the poetics elaborated by Vincent Jouve in his Poétique des valeurs (2001). Fol

A method for determination of the accessible volume fraction in gels as function of the molecular weight of the solutes is presented. The pore-size distribution is determined by measuring the rate of diffusion of a mixture of solutes into a gel using gel filtration for separation. The solutes, of various sizes, are detected by refractive index measurements. Two marker molecules (blue dextran and g

The photoreceptor cells of the nocturnal spider Cupiennius salei were investigated by intracellular electrophysiology. (1) The responses of photoreceptor cells of posterior median (PM) and anterior median (AM) eyes to short (2 ms) light pulses showed long integration times in the dark-adapted and shorter integration times in the light-adapted state. (2) At very low light intensities, the photorece

This study is based mainly on observations and interviews accomplished on two occasions with nursing assistants employed at two group living units for older people suffering from dementia in Sweden. The interviews and observations were carried out one year apart, before and after a project that also included supervision of managers and nursing assistants. I interviewed 12 nursing assistants, 8 of

During a validation process of the Swedish Knee Arthroplasty Register (SKAR), living registered patients were sent a questionnaire to ask if they had been reoperated on. This gave an opportunity to pose a simple four-point question with respect to patient satisfaction which 95% of patients answered. We analyzed the answers of patients operated on between 1981 and 1995 and found that only 8% of the

Vortices can form when finite quantal systems are set rotating. In the limit of small particle numbers, the vortex formation in a harmonically trapped fermion system, with repulsively interacting particles, shows similarities to the corresponding boson system, with vortices entering the rotating cloud for increasing rotation. For a larger number of fermions, N greater than or similar to 15, the fe

John Ternstedt (1844-1938) var en av de relativt få svenska präster som påverkades av Tübingerteologen J. T. Beck. Dessa kortfattade anteckningar innehåller inga teologiska analyser, men ger tydliga intryck av spiritualiteten i dessa kretsar med dragning åt mystik och distans till nyevangelismen. Vi får inblickar i såväl skolelevens som lantprästens tillvaro i en tid då präst och församlingsbor va

Airway mucus is regulated by many inflammatory mediators such as ILs, TNF-alpha, EGF, PGF2 alpha, LT, and so on. Recently, the relationship between membrane ion channel and Mucus production has been under investigation. The present study aimed to examine whether AQP5 was involved in modulation of mucin expression and secretion in airway submucosal gland cells (SPC-Al). A recombinant plasmid (pShAQ
