8He-6He: a comparative study of electromagnetic fragmentation reactions

Dissociation of a 227 MeV/u 8He beam in a lead target has been studied in a kinematically complete experiment. The results are compared with similar data from the well-known halo nucleus 6He. Coulomb–nuclear interference in the inelastic channel gives evidence for a Iπ=1− resonance in 8He at Ex=4.15 MeV. The deduced B(E1) value of 0.38±0.07 e2 fm2 indicates a uniform distribution of the four neutr

Starch in Processed Potatoes -Influence of Tuber Structure, Thermal Treatments and Amylose/Amylopectin Ratio

Popular Abstract in Swedish Potatis är ett av våra viktigaste baslivsmedel, men erbjuder trots det stor variation. Traditionella recept varvas med nya innovationer i hushåll och restauranger, och inom livsmedelsindustrin processas potatisen till en rad olika produkter. Från traditionell kokt potatis med sås inom husmanskosten har våra matvanor förändrats radikalt. Ökade krav på snabb och enkel tilThe potato is one of our most important food crops, being sold in its natural state or processed into a wide range of products. Starch, by far the most abundant component in the tuber, is greatly affected by heat processing. Therefore it is logical to study starch thermal properties within the tuber tissue, although most previous studies have focused on starch-water model systems. One of the main

A Current Swedish Survey on Attitudes to Science-and-Religion

Artikeln presenterar resultat från en enkätundersökning bland 2000 personer bosatta i Sverige. I enkäten ställdes bland annat frågor om synen på förhållandet mellan naturvetenskap och religion. Resultaten ger vid handen att man uppfattar naturvetenskap och religion som kompletterande varandra, och att denna uppfattning är vanligare med högre utbildning. Uttalade ateister uppfattar i hög utsträckni

Challenges in Designing Resilient Socio-technical Systems: A Case Study of Railway Tunnel Projects

This paper presents a case study of decision-making at the design stage of a socio-technical system where resilience at the global level of the system was constrained by the local perspectives adopted by the different stakeholders. The study is based on interviews with key decision-makers involved in the design stage of six railway tunnel projects in Sweden. The results show that differences in ro

Core-Level Expansion of Compressed Test Patterns

The increasing test-data volumes needed for the testing of system-on-chip (SOC) integrated circuits lead to long test-application times and high tester memory requirements. Efficient test planning and test-data compression are therefore needed. We present an analysis to highlight the fact that the impact of a test-data compression technique on test time and compression ratio are method-dependant a

ACOUSTOELASTIC EFFECTS ON THE NATURAL FREQUENCIES OF PRE-STRESSED CONCRETE BEAMS

Abstract in Undetermined Pre-stressed concrete is used to increase the load capacity in many civil engineering structures. There is a need for non-destructive methods to estimate the potential loss of pre-stress in these structures. In this study we investigate the acoustoelastic effect on the natural resonance frequencies of a pre-stressed concrete beam. Measured resonant frequencies increase wit

The Plasminogen Activation System in Human Endometrium and Endometrial Cancer; Function, Tissue Localization and Prognostic Importance

Popular Abstract in Swedish I avhandlingen studeras plasminogenaktiverings-systemets (PA-systemets) komponenter i livmoderslemhinnan. PA-systemet reglerar omvandlingen av plasminogen till plasmin. Plasminogen är ett inaktivt enzym som finns överallt i kroppsvätskor samt i kroppens olika organ. Aktiveringen katalyseras av aktivatorer, antingen urokinase plasminogen activator (uPA) eller tissue plasThe release of urokinase plasminogen activator (uPA) from endometrial stromal cells decreased after progesterone stimulation, due to upregulation of PA inhibitor 1 (PAI-1) and uPA receptor (uPAR). Subsequently, the uPA:PAI-1 complex was internalized and degraded via uPAR. Predecidual cells in the late secretory phase expressed PAI-1 and uPAR, supporting a specific role for predecidual cells in the

Analysis of Fire Scenarios in Order to Ascertain an Acceptable Safety Level in Multi-Functional Buildings

The construction of multifunctional buildings has increased over the last years as well as the threat level considering antagonistic events. This presents challenges for the fire safety in these types of buildings since the protection objectives needs to be more focused on the functions the buildings are providing. Further the antagonistic exposures might present more challenging fire scenarios. A

Cystatin C functions in vitro and in vivo. Studies on target enzyme inhibition by cystatin C variants and cystatin C deficient mice.

Popular Abstract in Swedish Studier av cystatin C's funktion in vitro och in vivo.Cystatin C variants with Arg8, Leu9 and/or Val10 replaced by Gly residues were produced by site-directed mutagenesis and E. coli expression. Their interactions with the target proteases, cathepsin B, L, H and S, were studied in vitro in order to provide basic structure-function information of use in the design of specific inhibitors for therapeutic use. Val10 was shown to be the most contributing

Biofuels for Transport in Australia

In Australia, policy at the National and State levels induces and blocks the development of biofuels. There is no strong, integrated and consistent policy framework. The market for biofuels lacks momentum and confidence of investors is weak. Current capacity is not utilised. Expansion is not expected before 2015.

Optimal stochastic discrete time–frequency analysis in the ambiguity and time-lag domain

In stochastic time-frequency analysis, the covariance function is often estimated from only one observed realization with the use of a kernel function. For processes in continuous time, this can equivalently be done in the ambiguity domain, with the advantage that the mean square error optimal ambiguity kernel can be computed. For processes in discrete time, several ambiguity domain definitions ha

Reframing the Multilevel Triple Helix in a Regional Innovation System: A case of systemic foresight and regimes in renewal of Skane’s food industry

Most organizational findings on Triple Helix modes of interaction have originated in studies of high-tech sectors and emergent industries, whereas low-tech sectors and mature industries to a less extent have been explored in the Triple Helix literature. A foresight initiative aiming at an enhanced renewal of the mature food industry in the region of Skane, was conducted 2006-2007. Findings from th
