A detector system for studying nuclear reactions relevant to Single Event Effects

We describe a device to study reactions relevant for the Single Event Effect (SEE) in microelectronics by means of 200A and 300AMeV, inverse kinematics, Si + H and Si + D reactions. The work is focused on the possibility to measure Z = 2-14 projectile fragments as efficiently as possible. During commissioning and first experiments the fourth quadrant of the CELSIUS storage ring acted as a spectrom

Emergence of a Welfare State - Social Insurance in Sweden in the 1910s

Two important dimensions of the Swedish social insurance system are those of universality (encompassing the entire population) and of compensation for loss of income. The decisions basic to the Swedish social insurance system and thus to the Swedish Welfare State were made during the 1910s. A universal pension insurance system was decided upon in 1913. This was the world's first universal public i

Helicity dependence of the (gamma)over-right-arrow (p)over-right-arrow -> n pi(+) pi(0) reaction in the second resonance region

The helicity dependence of the total cross section for the (γ) over right arrow(p) over right arrownpi(+) pi(0) reaction has been measured for the first time at incident photon energies from 400 to 800 MeV The measurement was performed with the large acceptance detector DAPHNE at the tagged photon beam facility of the MAMI accelerator in Mainz. This channel is found to be excited predominantly whe

The HCCI Engine – High Load Performance and Control Aspects

Popular Abstract in Swedish Förbränningsmotorer används på flera platser i samhället där energi behöver göras tillgänglig i form av mekaniskt arbete eller elektrisk energi. Den kanske mest kända tillämpningen är som kraftkälla i en personbil. Förbränningsmotorerna har givetvis ett antal fördelar som bidragit till deras popularitet och omfattande användning - lågt pris, kompakthet, driftsäkerhet ocCurrent combustion engines provide excellent performance for vehicle propulsion and power generation. However, recent demands from society ask for higher efficiencies and lower emissions. These requirements are hard to meet with current technology and call for new solutions. Homogeneous Charge Compression Ignition, HCCI, offers a potential to combine high efficiency with very low emissions. It op

Responsive polymer gels: Double-stranded versus single-stranded DNA

Cross-linking of polyelectrolytes such as DNA gives gels that are osmotically highly swollen but contract upon addition of electrolytes and, in particular, upon association of oppositely charged cosolutes with the polyelectrolyte chain. The deswelling behavior of cross-linked DNA gels thus reflects the DNA-cosolute interactions and provides a basis for the development of responsive DNA formulation

A database of exposures in the rubber manufacturing industry: Design and quality control

The concerted action EXASRUB was initiated to create a database management system for information on occupational hygiene measurements that could be used to develop exposure models in the European rubber manufacturing industry. Quality of coding was assessed by calculating percentages of agreement and Cohen's kappa statistics (kappa) for an intra- and inter-centre recoding of randomly selected sub

Contractile response in isolated human groin lymphatics

Lymphatics from the human superficial groin removed at operation in 21 patients (one with lymphedema) were examined in vitro. Histochemically no nerves were identified with either specific catecholamine fluorescence or immunoreactivity to tyrosine hydroxylase or dopamine beta-hydroxylase. Ring preparations of the lymphatics were mounted in tissue baths and isometric induced contractions were recor

Electrochemical investigation of cellobiose dehydrogenase from new fungal sources on Au electrodes

Following previous electrochemical investigations of cellobiose dehydrogenase (CDH), the present investigation reports on the initial screening of the electrochemistry of three new CDHs, two from the white rot basidiomycetes Trametes villosa and Phanerochaete sordida and one from the soft rot ascomycete Myriococcum thermophilum, for their ability to directly exchange electrons with 10 different al

Phenotypic expression of the complete type of X-linked congenital stationary night blindness in patients with different mutations in the NYX gene

Purpose: To describe the clinical phenotype of the complete type of X-linked congenital stationary night blindness (CSNB1) with different types of mutations in the NYX gene. Methods: The clinical and genetic data from 18 male patients with eight different mutations from two ophthalmological institutes were reviewed. The variability in refractive error, reduced visual acuity and full-field electror

Shears band in the Sn-105 nucleus

The structure of Sn-105 has been investigated through the Cr-50(Ni-58, 2pn) reaction at a beam energy of 210 MeV. In addition to an extension of the spherical level scheme, a regular sequence of dipole transitions has been found. The experimental results are in agreement with the prediction of Tilted Axis Cranking calculations, which satisfactorily explain the properties of the band.
