Attosecond dynamics of electron wave packets in intense laser fields

We use a train of sub-200 attosecond extreme ultraviolet (XUV) pulses with energies just above the ionization threshold in argon to create a train of temporally localized electron wave packets. We study the energy transfer from a strong infrared (IR) laser field to the ionized electrons as a function of the delay between the XUV and IR fields. When the wave packets are born at the zero crossings o

Fusion enligt ABl 14:8 - en skatte-, bolags, och redovisningsrättslig studie

Summary in English This dissertation bears the title "Fusions as defined by the Swedish Companies Act 'ABL' of 1975 (14:8) - a study of tax, corporation and accountancy legislation". The dissertation constitutes a study of fusions from the perspective of (as the title suggests) taxation, corporation and accountancy legislation. The Swedish Companies Act (ABL) includes rules concerning two forms o

The brief study aims to identify the genesis of the first dramatic protagonist Mihail Sebastian imagined, both the autobiographical and the literary earlier experiences and expressions of his playwriting philosophy of the evasion, a philosophy that is to be regarded as a prototype for his future drama. For this a rather exhaustive synthesis of the critical references is required as well as a minut

Oxidation of Pyrite by Acidianus brierleyi: Importance of Physical Contact Between the Pyrite and the Microorganisms

Experiments were done in order to study the thermophilic archaebacterium Acidianus brierleyi during oxidation of pyrite (FeS2). The microorganisms were grown both separated from the pyrite by a membrane and in close contact with the pyrite. From the results it can be concluded that direct contact is needed for good growth of the strain studied. The obtained results indicated that the direct contac

Magnetic properties of GaMnAs single layers and GaInMnAs superlattices investigated at low temperature and high magnetic field

Magnetotransport properties of GaMnAs single layers and InGaMnAs/ InGaAs superlattice structures were investigated at temperatures from 4 K to 300 K and magnetic fields up to 23 T to study the influence of carriers confinement through different structures. Both single layers and superlattice structures show paramagnetic-to-ferromagnetic phase transition. In GaMnAs/InGaAs superlattice beside the Cu

Two- and three-body correlations: breakup of halo nuclei

Nuclear knockout reactions at relativistic energies provide a sensitive tool to determine the ground state properties of nuclei close to the drip line. Studies with kinematically complete measurements reveal the initial correlations in the reacting systems and yield spectroscopic information on the continuum states populated in the decay channel. The coincident data of charged fragments and neutro

Partitioning of hydrophobic amino acids and oligopeptides in aqueous two-phase system containing self-aggregating block copolymer - Effects of temperature, salts and surfactants

The partitioning of hydrophobic amino acids and oligopeptides in the Pluronic P105-dextran-water system has been studied. Pluronic P105 is a member of a family of triblock copolymers with the structure PEO-PPO-PEO, where PEO is poly(ethylene oxide) and PPO poly(propylene oxide). The partitioning was studied for tryptophan, phenylalanine and di- and tri-peptides composed of these amino acids at 5 a

Teaching Top Down Design of Analog/Mixed Signal ICs Through Design Projects

This paper describes a project course that focuses on the design of analog and mixed signal circuits through a systematic top down design flow. In the project, the student will be involved in the planning, modeling, circuit level design, physical level implementation and measurement verification of for example a successive approximation (SA) ADC or a class-D audio amplifier. Throughout the project

Diabetes och tobak - dubbla hot mot hälsan

Smoking is a serious risk factor for cardiovascular disease, retinopathy, and nephropathy in patients with diabetes. Furthermore, epidemiological studies have shown that heavy smokers run an increased prospective risk of developing type 2 diabetes, probably due both to the fact that smoking is a marker for an unhealthy lifestyle and that smoking via nicotine may deteriorate glucose metabolism by n

Tubular repair of the median or ulnar nerve in the human forearm: a 5-year follow-up.

The long-term outcome from silicone tube nerve repair was compared with the outcome from routine microsurgical repair in a clinical randomized prospective study, comprising 30 patients with median or ulnar nerve injuries in the distal forearm. Postoperatively, the patients underwent neurophysiological and clinical assessments of sensory and motor function regularly over a 5-year period. After 5 ye

Geographical variation in incidence of prostate cancer in Sweden - Survey from the National Prostate Cancer Register

Objective. To investigate the geographical variation in prostate cancer incidence in Sweden, in particular the incidences of screening-detected tumours and curative treatment of prostate cancer. Material and methods. Data were retrieved from the National Prostate Cancer Register of Sweden for all cases of prostate cancer diagnosed in the year 2000-01. There were a total of 14 376 cases of prostate

Upconversion dynamics in Er3+-doped YAG

Green, blue, violet and ultraviolet upconversion luminescence is reported at room temperature in a YAG: 10.5% Er3+ crystal pumped by one-colour (647 nm) and two-colour (647 + 618 nm) laser excitation. The upconversion mechanism was studied by means of time-resolved luminescence spectroscopy and the energy flow pathways are described. Based on the results it appears that energy transfer upconversio

Lärares förtroendearbetstid

Popular Abstract in Swedish Det övergripande området för min studie är lärararbetet. Initialt riktar jag blickarna mot lärare som verkar i den svenska grundskolan. Den övergripande forskningsfrågan lyder: Hur är lärararbetet? Även om det i grundad teori framstår som önskvärt att forskaren ska ge sig ut på fältet utan förutfattade idéer och perspektiv som tvingar data in i förutbestämda analyser, gThe aim of this study is to generate a grounded theory about the work done by teachers. The initial area of data collection was the work done by teachers in their non-regulated hours, in which the teachers are expected to carry out professional activities like planning, preparation, correcting and spontaneous contacts with students, parents and colleagues. Data was collected and analysed according

Replication and construct validation of the Barrow Neurological Institute Screen for Higher Cerebral Function with a Swedish population.

A Swedish translation of the Barrow Neurological Institute Screen for Higher Cerebral Functions was administered to 52 normal control subjects and 36 patients with well-documented brain dysfunction. Findings replicated those reported in American samples. Level of performance was strikingly similar between Swedish controls and American controls, especially in individuals between 15 and 39 years.

The aim of this study was to assess the frequency and prognostic value of TP53 gene somatic mutations in non-small cell lung cancer. The study group included 240 NSCLC patients who underwent pulmonary resection at the Department of Thoracic Surgery, Medical University of Gdansk. Tumour samples were evaluated for the presence of TP53 gene mutations in exons 5-8. In 157 cases SSCP method was used as

Analysis of 5-hydroxy-N-methyl-2-pyrrolidone and 2-hydroxy-N-methylsuccinimide in plasma

A method for the determination of 5-hydroxy-N-methyl-2-pyrrolidone (5-HNMP) and 2-hydroxy-N-methylsuccinimide (2-HMSI) in plasma was developed. 5-HNMP and 2-HMSI are metabolites to the widely used organic solvent N-methyl-2pyrrolidone (NMP). The 5-HNMP and 2-HMSI were purified from plasma by C8 solid phase extraction, derivatised by bistrimethylsilyl trifluoroacetamid, and analysed by gas chromato
