The near-infrared spectrum of upsilon Sagittarii has been registered using the SOFIN high resolution spectrometer on the Nordic Optic Telescope, La Palma. For the first time 4f-5g transitions of Fe II in any astrophysical spectrum have been identified. Optical region spectra with the high resolution SOFIN spectrograph have been analysed for determination of elemental abundances and spectral line i

Popular Abstract in Swedish Avhandlingens titel: Självskadebeteende bland ungdomar: resultat från tvärsnitts- och longitudinella studier i svenska skolor. Självskadebeteende bland ungdomar (exempelvis när någon skär, bränner eller slår sig själva, eller avsiktligt åsamkar sig direkta skador på något annat sätt) har uppmärksammats som ett växande problem under de senaste årtiondena. Kunskap om omfaSelf-injury in adolescents (e.g. when individuals cut, burn, hit or otherwise deliberately cause themselves direct injury), has gained recognition as a potentially important mental health problem during the past decade. Relatively little has been known about the scope and characteristics of this behavior in Swedish adolescents. This thesis consists of three studies that in different ways explore

Abstract in UndeterminedWe examined how hypnotizability, dissociation, alterations in consciousness, belief in success, and previous psi experiences related to performance in a ganzfeld psi task. High (n = 14) and low (n = 12) hypnotizables participated in 2 sessions. The first included measures of dissociation and alterations in consciousness during ganzfeld, whereas the second consisted of a tel

Procedures for sample clean-up and concentration in Capillary Zone Electrophoresis (CZE) have been developed for determination of drugs in biosample s. An on-capillary concentration technique based on enhanced field strengths, the double stacking procedure is introduced. This procedure allows for concentrationg all cations in the sample several hundred times essentially without loss of separation

This paper investigates the use of corpora, with a specific focus on concordances,in teaching and learning as a foreign language in classrooms in Vietnam. Students who used concordances obtained more correct answers than those who did not, and they could develop activeness in exploring words structures and grammatical rules.

Shallow lakes such as Lake Krankesjön are characterized by their extended littoral zones, usually covered by submersed and emergent vegetation. In paper 1, I investigated the relationship between turbidity and macrophyte growth (Chara spp.) during spring and summer in Lake Krankesjön and found that the colonization of the lake bed by macrophytes was dependent on turbidity on a non-linear way. Also

Microstructural evolution during the early stages of ageing (less than one hour) in a Ni-Cr-Fe based superalloy Inconel 718 (IN718) has been investigated using Small-Angle X-ray Scattering (SAXS). The effects of precipitate kinetics on the precipitate size distribution are compared indirectly with SAXS measurements by using Vickers microhardness data. The microhardness increased after 4 min of age

Super-obesity, a body mass index>50 kg/m(2), is difficult to treat. Many studies have focused on the anatomic changes of the intestines; the physiologic background is not clearly identified. It is established that Roux-en-Y gastric bypass (RYGB) augments secretion of glucagon-like peptide-1 (GLP-1), peptide tyrosine tyrosine (PYY), and insulin, but other aspects of gut hormone cell function in the

The purpose of this study was to determine whether administration of postoperative antibiotics affects the incidence of complications after primary cleft palate repair in a developing area.

The ability to control the movement of nanoparticles remotely and with high precision would have far-reaching implications in many areas of nanotechnology. We have designed a unique dynamic magnetic field (DMF) generator that can induce rotational movements of superparamagnetic iron oxide nanoparticles (SPIONs). We examined whether the rotational nanoparticle movement could be used for remote indu

The liver is a critical organ for regulation of energy homeostasis and fatty liver disease is closely associated with obesity and insulin resistance. We have previously found that lingonberries, blackcurrants and bilberries prevent, whereas açai berries exacerbate, the development of hepatic steatosis and obesity in the high-fat (HF)-fed C57BL/6J mouse model. In this follow-up study, we investigat

The aim of this study was to employ an experimental protocol for in vivo evaluation of sols of 5 wt.\% poly(ethylene glycol) (PEG) in phosphate buffered saline (PBS) as artificial vitreous substitutes. A 20 gauge pars plana vitrectomy and posterior vitreous detachment were performed in the right eye of 8 pigmented rabbits. Approximately 1 mL of the viscoelastic PEG sols were then injected into the
