We have prepared and studied a new class of anion conducting membrane materials functionalized with N-spirocyclic quaternary ammonium (QA) cations formed via cyclo-quaternization reactions involving pyrrolidine, piperidine and azepane, respectively. These groups were introduced in pairs, adjoined through fused phenyl rings along poly(arylene ether sulfone) backbones. Despite their bulkiness, the b

The diversity and abundance of wild insect pollinators have declined in many agricultural landscapes. Whether such declines reduce crop yields, or are mitigated by managed pollinators such as honey bees, is unclear. We found universally positive associations of fruit set with flower visitation by wild insects in 41 crop systems worldwide. In contrast, fruit set increased significantly with flower

Here we present the results of a study of the electronic structure using the resonant inelastic scattering process at the F 1s photoabsorption edge in LiF and O 1s edge of MgO crystals. In case of excitations in the sub-threshold region, the Raman-type linear dispersion of X-ray fluorescence peak was observed for the studied compounds. In LiF, the narrowing of the X-ray fluorescence peak is observ

Dijet events in photon-proton collisions in which there is a large pseudorapidity separation, Deltaeta > 2.5 between the two highest E-T jets are studied with the H1 detector at HERA. The inclusive dijet cross sections are measured as functions of the longitudinal momentum fractions of the proton and photon which participate in the production of the jets, x(p)(jets) and x(gamma)(jets) respectively

Popular Abstract in Swedish Spel om pengar har blivit ett utbrett fenomen i Sverige under 1990-talet, med spelbutiker, spelhörnor i varuhusen, spelmaskiner och spel med kort och på roulette på pubar, pizzerior och restauranger, samt spel på Bingo-Lotto hemma i vardagsrummet. Förutom den ökade tillgången till legala spelformer blir det allt vanligare med spel i miljöer och sammanhang där det inte fGambling has become widely accepted in Sweden during the 1990s, with betting shops, gambling machines and casino-like gambling in pubs and restaurants, as well as Bingo-Lotto in our living rooms. Beyond the expansion in availability of legal gambling opportunities, the most notable change is the shift from gambling in specific venues to gambling in a much wider range of social settings. The conseq

Popular Abstract in Swedish Gangesfloden i Varanasi (Indien) anses samtidigt vara fullkomligt ren och svårt förorenad, beroende på vem som definierar dess egenskaper, brahminska religiösa specialister eller vetenskapligt orienterade miljöaktivister. Medan kontroversen fortgår, försöker några hinduiska religiösa ledare att anpassa sina traditioner till de nya miljöparadigmen, och deras förhållningsWhether the Ganges river in Varanasi (India) is pristinely pure or heavily polluted depends on by whom it qualities are defined, the Brahmin religious specialists in the city or the science oriented environmentalists. While the controversy continues, some Hindu religious leaders are searching for ways to adjust their respective traditions to the environmental paradigms, an initiative that reflects

Asthma is characterized by an airway remodeling process involving altered extracellular matrix deposition such as collagen, fibronectin and proteoglycans. Proteoglycans determine tissue mechanical properties and are involved in many important biological aspects. Not surprisingly, it has been suggested that proteoglycan deposition may alter airway properties in asthma including airway hyperresponsi

The effect of pulsed electric field (PEF) pretreatment on solid-liquid expression from potato tissue was studied on individual parenchyma tissue samples for different PEF intensities, varying relative deformations and deformation rates. The yield increased with relative deformation. The yield at any given relative deformation increased with increased PEF intensity and decreased deformation rates.

Rapporten behandlar utformning av anslutningen mellan yttervägg och platta på mark samt dess inverkan på fukttillståndet i syllar av främst trämaterial. Undersökningen omfattade dels fältmätningar och dels koretiska beräkningar, dessutom gjordes en del laboratorieförsök. Rekommendationer för utformning.

Taxa within the Dactylorhiza incarnata/maculata species complex form a diploid and tetraploid complex. The genetic variation revealed by molecular markers indicate that this is a young complex and that polyploidization may be an ongoing process; most, if not all, of the polyploid taxa may have evolved after the last ice age. This conclusion is supported by 1) a close correspondence in general dist

Responses to isotonic quick release of AC-stimulated smooth muscle strips from rabbit urinary bladder were analysed. Releases were performed at the peak of contraction and at a preset tension level in the contraction and relaxation phase. In other expts. responses at 37 degrees C and 27 degrees C were compared. The length response always consisted of 3 parts: (1) elastic recoil, (2) rapid length c
