A first comparison has been made between the pulse-shape discrimination characteristics of a novel He-4-based pressurized scintillation detector and a NE-213 liquicl-scintillator reference detector using an Am/Be mixed-field neutron and gamma-ray source and a high-resolution scintillation-pulse digitizer. In particular, the capabilities of the two fast neutron detectors to discriminate between neu
The global speed of change within the manufacturing industry forces companies to constantly improve production performance. In that effort, performance measures are critical for driving and managing production improvements. Two of the most commonly used measures in operations are productivity and overall equipment efficiency (OEE). However, the potential of using these measures as improvement driv
Using a novel dataset of regional GDP per worker from 1860 to 2009, this paper analyzes communalities in regional long-term growth trajectories for 24 Swedish regions. Wavelet Analysis and Principal Component Analysis are used to decompose regional growth trajectories and assess the extent that regional growth patterns share common trends and cyclical properties. The study found that regional grow
There is growing evidence of the importance of extramatrical mycelium (EMM) of mycorrhizal fungi in carbon (C) cycling in ecosystems. However, our understanding has until recently been mainly based on laboratory experiments, and knowledge of such basic parameters as variations in mycelial production, standing biomass and turnover as well as the regulatory mechanisms behind such variations in fores
The recently isolated anaerobic bacterium Caloramator boliviensis with an optimum growth temperature of 60°C can efficiently convert hexoses and pentoses into ethanol. When fermentations of pure sugars and a pentose-rich sugarcane bagasse hydrolysate were carried out in a packed bed reactor with immobilized cells of C. boliviensis, more than 98% of substrates were converted. Ethanol yields of 0.40
Cobalamins belong to the tetrapyrrole family of prosthetic groups(.) The presence of a metal ion is a key feature of these compounds. In the oxygen-dependent (aerobic) cobalamin biosynthetic pathway, cobalt is inserted into a ring-contracted tetrapyrrole called hydrogenobyrinic acid a,c-diamide (HBAD) by a cobaltochelatase that is constituted by 3 subunits, CobN, CobS and CobT, with molecular mass
Global patterns in soil, plant, and fungal stable isotopes of N (delta N-15) show promise as integrated metrics of N cycling, particularly the activity of ectomycorrhizal (ECM) fungi. At small spatial scales, however, it remains difficult to differentiate the underlying causes of plant delta N-15 variability and this limits the application of such measurements to better understand N cycling. We co
As an assignment in their course of Worldwide Religions, a group of Swedish High School pupils followed 12 biblical rules for two weeks, while another group from the same school just imagined the experience. Groups were asked to reflect and write down either how it was (experience) or how it would have been (imagine) to follow the rules. By applying a semantic test, based on a Latent Semantic Anal
New elasmosaurid plesiosaur specimens are described from the Early Maastrichtian of Angola. Phylogenetic analyses reconstruct the Angolan taxon as an aristonectine elasmosaurid and the sister taxon of an unnamed form of similar age from New Zealand. Comparisons also indicate a close relationship with an unnamed form previously described from Patagonia. All of these specimens exhibit an ostensibly
The implementation of gender fair language is often associated with negative reactions and hostile attacks on people who propose a change. This was also the case in Sweden in 2012 when a third gender-neutral pronoun hen was proposed as an addition to the already existing Swedish pronouns for she (hon) and he (han). The pronoun hen can be used both generically, when gender is unknown or irrelevant,
The aim of this paper is to investigate the spatial pattern of knowledge links in traditional, long-established, and less-research-intensive sectors and to contribute to a better understanding of the role of the regional innovation system (RIS) as space for knowledge-sourcing activities in such industries. Departing from conceptual work on the science, technology, and innovation (STI) and the doin
OBJECTIVE:: To compare employees' and managers' perceptions of implemented changes in an organizational-level workplace intervention. METHODS:: Nine departments participated in an intervention aimed at reducing adverse psychosocial work environment factors. On the basis of a prior risk evaluation, department managers were responsible for decisions and implementation of the intervention, that is, w
The coiled-coil protein DivIVA is a determinant of apical growth and hyphal branching in Streptomyces coelicolor. We have investigated the properties of this protein and the involvement of different domains in its essential function and subcellular targeting. In S. coelicolor cell extracts, DivIVA was present as large oligomeric complexes that were not strongly membrane associated. The purified pr
In Public Reading in Early Christianity: Lectors, Manuscripts, and Sound in the Oral Delivery of John 1-4 Dan Nässelqvist investigates the oral delivery of New Testament writings in early Christian communities of the first two centuries C.E. He examines the role of lectors and public reading in the Greek and Roman world as well as in early Christianity. Nässelqvist introduces a method of sound ana
Popular Abstract in Swedish Stamceller är unika celler som har möjlighet att både förnya sig själva och ge upphov till en mängd mogna celler. Den ultimata stamcellen är det befruktade ägget, som är den cell som efter omfattande celldelning kommer att ge upphov till alla vävnader och celler i den färdigutvecklade kroppen. Dessa celler kallas därför pluripotenta. Även i den färdigutvecklade kroppen Hematopoiesis is the process of blood formation that originates with the hematopoietic stem cell (HSC), a cell type that is responsible for the life-long supply of mature blood cells. HSCs are defined by their ability to self-renew as well as giving rise to differentiated cells of all blood lineages. Because of these features, HSCs are also the basis for bone marrow transplantation regimens for tr
