The 2s and 2p photoelectron spectra have been measured for Na(+), Mg(2+), and Al(3+) ions in aqueous solution. In all cases, the 2s lines are significantly broader than the 2p features, which is attributed to a shorter lifetime of the respective 2s hole. Since intraionic Coster-Kronig decay channels from the (2s)(-1) state are closed for free Na(+), Mg(2+), and Al(3+) ions, this is evidence for an

Background: Hybridization and polyploidy are potent forces that have regularly stimulated plant evolution and adaptation. Dactylorhiza majalis s.s., D. traunsteineri s.l. and D. ebudensis are three allopolyploid species of a polyploid complex formed through unidirectional (and, in the first two cases, recurrent) hybridization between the widespread diploids D. fuchsii and D. incarnata. Differing c

Motivated by recent experiments in Bose-Einstein condensed atoms that have been confined in toroidal traps, we examine the stability of persistent currents in such systems. We investigate the extent that the stability of these currents may be tunable, and the possible difficulties in their creation and detection.

Background: Moths have evolved highly successful mating systems, relying on species-specific mixtures of sex pheromone components for long-distance mate communication. Acyl-CoA desaturases are key enzymes in the biosynthesis of these compounds and to a large extent they account for the great diversity of pheromone structures in Lepidoptera. A novel desaturase gene subfamily that displays Delta 11

CapsuleHouse Sparrow (Passer domesticus) populations in south Swedish farmland are not affected by supplemental winter feeding, irrespective of agricultural landscape type or presence of animal husbandry, although winter populations declined more in mixed farmland and when farms contained animal husbandry. AimsTo investigate whether food limitation of House Sparrow population size during the winte

Popular Abstract in Swedish Barn och ungdomar med hörselnedsättning har, i högre grad än jämnåriga kamrater utan hörselnedsättning, språkliga problem. Dessa problem märks när barnen gått några år i skolan och större krav ställs på deras läsförmåga och på deras förmåga att uttrycka sig i tal och skrift. Problemen kan yttra sig tidigt och på olika sätt, som svårigheter med att uttala och särskilja sThe aim of the present thesis was to explore reading comprehension and narration in children and adolescents with different degrees of hearing impairment (HI). In Study I, reading comprehension was investigated in 16 children with cochlear implants (CI), aged 7-13 years. Over 60% of the investigated children performed at the level of their hearing peers. Reading comprehension was better than expec

Surface ice in rivers and lakes buffers the thermal environment and provides overhead cover, protecting aquatic animals from terrestrial predators. We tested if surface ice influenced the behavior (swimming activity, aggressive encounters, and number of food items eaten) and stress level (coloration of eyes and body) of stream-living brown trout Salmo trutta at temperatures of 3-4 degrees C in ind

The report provides guidance on how to assure quality in fire safety analysis reports. The primary focus is on analyses in nuclear power plants but the report can also be used for other applications as the information can be seen as generic. The report provides a procedure to follow and targets at analytical fire safety engineering analyses. The report assumes that the reader is familiar with the

Activated sludge models (ASMs) have been widely used as a basis for further model development in wastewater treatment processes. Values for parameters to be used are vital for the accuracy of the modeling approach. A continuous stirred tank reactor (CSTR), as open respirometer with continuous flow for 20 h is used in ASMs. The dissolved oxygen (DO) profile for 11 days was monitored. It was found t

The surface emissions trap, an adsorption cloth developed for reducing emissions of volatile organic compounds and particulate matter from surfaces while allowing evaporation of moisture, was used to improve the indoor air quality of a school building with elevated air concentrations of 2-ethyl-1-hexanol. An improvement of the perceived air quality was noticed a few days after the device had been

Våra genomströmningsresultat visar på en markant positiv utveckling för varje år. Vi ställer oss frågan: Är det den allt större flexibiliteten som vi skapar inom våra kurser som kan vara motivet?

Rationale: As support in leading a meaningful and active life, a person with mental illness is often given the opportunity to attend a day centre. However, few studies have investigated the meaningfulness perceived by the person visiting a day centre. For such a purpose, a self-report instrument was developed. Aims: To explore whether perceived meaningfulness, as expressed in the recently develope

OBJECTIVE-Young children have an unacceptably high prevalence of diabetic ketoacidosis (DKA) at the clinical diagnosis of type I. diabetes. The aim of this study was to determine whether knowledge of genetic risk and close follow-up for development of islet autoantibodies through participation in The Environmental Determinants of Diabetes in the Young (TEDDY) study results in lower prevalence of D

This thesis is about the intersection between Corporate Social Responsibility and Supply Chain Management. I call this upstream CSR, the phenomenon that arises when an issue on a company’s CSR agenda becomes an issue for its sourcing and supply management operations. Upstream CSR as a phenomenon is not without controversies, but it also holds an important potential for reducing negative environm

We present the design and fabrication of a polymeric capillary fluidic interface fabricated by micro-milling. The design enables the use of glass capillaries with any kind of cross-section in complex microfluidic setups. We demonstrate two different designs of the interface; a double-inlet interface for hydrodynamic focusing and a capillary interface with integrated pneumatic valves. Both capillar

Milk with extended shelf-life can be produced by microfiltration (MF) and pasteurisation in a cascade arrangement. In a previous study, we have shown that back-pulsing can be used to reduce the energy requirement in the MF of defatted milk. In this study, the influence of back-pulsing on MF was investigated at higher milk fluxes than in a prior study. The MF experiments were performed in constant-

[1] A forward atmospheric transport modeling experiment has been coordinated by the TransCom group to investigate synoptic and diurnal variations in CO2. Model simulations were run for biospheric, fossil, and air-sea exchange of CO2 and for SF6 and radon for 2000-2003. Twenty-five models or model variants participated in the comparison. Hourly concentration time series were submitted for 280 sites

The Italian Sarcoma Group and the Scandinavian Sarcoma Group designed a joint study to improve the prognosis for patients with Ewing's family tumors and synchronous metastatic disease limited to the lungs, or the pleura, or a single bone. The study was opened in 1999 and closed to the enrollment in 2008. The program consisted of intensive five-drug combination chemotherapy, surgery and/or radiothe
