In an earlier paper we reported on a new septum magnet design with a magnetic flux filter [1]. Now the first septum magnet is in operation as in injection septum magnet for the MAX I storage ring. We dcscribe the actual mechanical construction and the field measurements of the new magnets. The fine Structure of the septum nose needed several trials in the construction until we found the final solu

Today, as a rule, the most cost-effective way to remove nitrogen from municipal wastewater is the biological method based on nitrification and subsequent denitrification. All biological systems may be affected by toxicants, and biological nitrogen removal is no exception. An investigation of influent wastewaters from 109 Swedish municipal wastewater treatment plants was accomplished. Inhibitory s

The thesis focuses on the numerical simulation of the flow field in gas turbine burners. Due to tougher and tougher requirements on low levels of emission of pollutants there is a need for new combustion technologies. In gas turbines one method to attain low pollutant levels is the use of lean premixed combustion. However, in lean combustion, problems related to the flame stability can arise. Swi

A selective pressurized liquid extraction (SPLE) procedure capable of performing simultaneous extraction and clean-up has been demonstrated for multi-residue analysis of organochlorine pesticides (OCPs) in soil. The final method was performed at 100 degrees C for 3 x 10 min using acetone/n-heptane (1:1, v/v). Florisil was placed inside the extraction cell downstream the sample to remove interferin

Relativistic energy projectile fragmentation of Pb-208 has been used to produce a range of exotic nuclei. The nuclei of interest were studied by detecting delayed gamma rays following the decay of isomeric states. Experimental information on the excited states of the neutron-rich N = 126 nucleus, Pt-204, following internal decay of two isomeric states, was obtained for the first time. In addition,

The purpose of this study was to define the bone metabolic properties during the postfracture period in elderly women with hip fracture. Osteocalcin (Oc), a marker of bone formation, was measured in 58 women with hip fracture (77 +/- 7 years) admitted to the hospital from their own homes. Serum samples were taken on average 5 h (range 1-21) from fracture and at follow-up, on average 4.6 months lat

Nuclear shell model calculations based on a modified harmonic-oscillator potential result in amazingly stable triaxial nuclear shapes. Major gaps in the single-particle energy spectra at proton number 71 and neutron number 94 combine constructively at low and intermediate rotational frequencies. At high frequencies, gaps at proton number 72 and neutron number 97 combine in an equally favourable wa

I denna avhandling används samtalsanalys (”conversation analysis”) för att studera ”riskstrategier” i samtal mellan lärare, elever och föräldrar i grundskolan. Materialet består av 80 samtal som insamlats vid två olika tidpunkter: 45 st. inspelade 1992–93 (kvartssamtal, eller den mer formella benämningen enskilda samtal) och ytterligare 35 st. inspelade 2004 (utvecklingssamtal, den benämning som gIn this thesis, conversation analysis (CA) is applied to study “risk strategies” in parent-teacher-student conferences in the Swedish nine-year compulsory school. The material consists of 80 conferences collected at two different points in time: 45 from the period 1992–93 (at that time called kvartssamtal, lit. “quarter of an hour conference”) and another 35 collected in 2004 (at the present time,

The aims of this study were to describe which self-care, productivity, and leisure occupations individuals with multiple sclerosis (MS) perceive as difficult to perform on admission to rehabilitation and the individuals' own perception of the importance of, performance of, and satisfaction with these occupations. Whether the reported self-care, productivity, and leisure occupations were related to

The presence of different isoenzymes of phosphatidylinositol 4-kinase in isolated rat liver plasma membranes and their further distribution in plasma membrane domains was examined. Both wortmannin-sensitive and -insensitive PtdIns 4-kinase activities were detected in highly purified plasma membranes obtained by aqueous two-phase affinity partitioning. The wortmannin-sensitive enzyme was identified

Incubation of cultured bovine vascular smooth muscle cells (VSMC) with forskolin increased cAMP as measured by an increase in cAMP-dependent protein kinase (PKA) activation (PKA ratio). Forskolin also produced a concentration- and time-dependent increase in activity (3-5-fold within 15 min) of a PDE4 (cAMP-specific cyclic nucleotide phosphodiesterase). The increase in PDE4 activity was not affecte

Objective. Most risk factors are similar for abdominal aortic aneurysm (AAA) and atherosclerosis, e.g. smoking, male gender, age, high blood pressure, hyperlipidemia. Diabetes mellitus however, is a risk factor for atherosclerosis, but diabetic patients seldom develop AAA. The reason for this discrepancy is unknown. Increased aortic wall stress seems to be all etiologic factor in the formation, gr

The paper deals with traffic recovery in IP/MPLS network carrying traffic of different priority classes. Two off-line network design problems are presented employing two different recovery mechanisms – single backup path and failure-dependent backup path protection. Also, two routing strategies are studied in this paper. A network design problem with failure-dependent path protection mechanism com

We present an experimental study of hard x rays produced in laser-produced plasmas. The laser used is a 1 kHz system, delivering 0.7 mJ for 25 fs onto a solid target. The x-ray spectrum was measured with calibrated germanium detectors, allowing a very good estimate of the absolute number of photons emitted from the plasma over a wide energy range; from 7 keV to 0.5 MeV. Assuming a bi-Maxwellian el
