A study was made of the damped oscillations in fibre length that are observed when isolated muscle fibres from the frog are released during the plateau of an isometric tetanus to shorten against a constant load (force clamp recording) near the isometric level (temperature, 1.0-11.0 C; initial sarcomere length, 2.25 m). 2. The oscillatory length changes of the whole fibre were associated with simil

Changes in the composition of carrot cell wall proteins were investigated, associating metabolic changes during long-term storage with changes in mechanical properties. Harvested carrots accumulate an antifreezing protein in their cell walls reaching a maximum level after 12 weeks of storage at 0°C, followed by a gradual decrease. During the same period of time, there is a decrease in the slicing

Sub-picosecond laser pulse driven localization of electronic excitation energy is suggested for a biological chromophore complex. Based on an exciton model of the photosynthetic core antenna PSI of Synechococcus elongatus the shape of the respective laser pulse is calculated using optimal control theory combined with a density matrix theory accounting for energy relaxation and dephasing caused by

Lifetimes of high spin states in the three A = 89 isobars Nb-89, (89)MO and (TC)-T-89 have been measured via the Recoil Distance Doppler Shift technique and the fusion evaporation reactions Ni-58(Cl-35, xnypz alpha) at 120 MeV beam energy. Reduced transition probabilities for about 50 gamma transitions were extracted. The experimental branching ratios in Mo-89 and reduced transition probabilities

Tidal marshes have recently been shown to be important biogenic Si recycling surfaces at the land-sea interface. The role of vegetation in this recycling process has not yet been quantified. In situ and ex situ decomposition experiments were conducted with Phragmites australis stems. In a freshwater tidal marsh, litterbags were incubated at different elevations and during both winter and summer. B

In sheep's fescue, Festuca ovina, genes coding for the cytosolic enzyme phosphoglucose isomerase, PGIC, are not only found at the standard locus, PgiC1, but also at a segregating second locus, PgiC2. We have used PCR-based sequencing to characterize the molecular structure and evolution of five PgiC1 and three PgiC2 alleles in F. ovina. The three PgiC2 alleles were complex in that they carried two

I samband med att Kvinnofridsreformen i Sverige 1998 uppdrog regeringen åt brottsoffermyndigheten att undersöka mörkertalet i fråga om mäns våld mot kvinnor som ett komplement till den officiella statistik som brottsförebyggande rådet normalt svarade för. Ansvaret för studien tilldelades Eva Lundgren, professor i sociologi och Gun Heimer, överläkare och chef för RiksKvinnoCentrum. Tillsammans med

The structure of nuclei far from beta-stability lines is expected to show various interesting and exotic phenomena, due to the unique features: (a) the presence of nucleons with very small binding energies and largely extended wave-functions; (b) large difference between the Fermi levels of protons and neutrons; (c) exotic ratios of the proton to neutron numbers for a given mass number. Among the

The project developed by three institutions in Denmark and Sweden –Malmoe School of Education, City Archives of Malmoe and the Cultural History Workshop in Denmark– uses the methods of oral history as an instrument in the production of historical awareness. It tries to elaborate multiple histories at several levels –nation, regional, local; ethnicized and gendered, social and political history– th

Popular Abstract in Swedish Syftet med denna avhandling är att undersöka mötet mellan den kyrkliga överheten och de olika lokalsamhällena sådant som det tog sig uttryck vid de kyrkliga visitationerna. I fokus står biskopsvisitationerna men även de visitationer som prostarna genomförde tas upp till behandling. Undersökningsområdet är Växjö stift och den tidsmässiga avgränsningen är 1650-1760. De frThe aim of this thesis is to investigate the encounter of the ecclesiastical authorities with the local community, as reflected in the church visitations. The focus is on the bishops' visitations, but there is also a brief examination of the deans' visitations, which are used for a comparison of the two types of inspections. The geographical limit of the study is the diocese of Växjö in southern S

Objectives. To estimate the point prevalence (p.p.) of Wegener's granulomatosis (WG), microscopic polyangiitis (MPA), polyarteritis nodosa (PAN) and Churg-Strauss syndrome (CSS) within a defined population in southern Sweden. Method. A cross-sectional p.p. study using multiple sources for case identification. The study area, a healthcare district around the city of Lund in southern Sweden (Mellers

New methods for spectrophotometric alkalinity measurement, dissolved hydrogen monitoring and for obtaining a fingerprint of the microbial community were evaluated as tools for process monitoring in anaerobic digestion. The anaerobic digestion process was operated at organic loading rates of 1.5, 3.0 and 4.5g volatile solids l-1d-1 and subjected to pulse loads of carbohydrate, lipid, protein and a

Chromosomal rearrangements involving chromosome bands 12q13-15 are very frequent findings in benign solid tumors, and recently, the primary molecular target for these aberrations was identified as the gene HMGIC. However, mutations in this gene have also been observed in nonneoplastic tissues. In a previous study, we reported breakpoints within HMGIC of synovia affected by osteoarthritis (OA) in t

The ubiquitin E3 ligase Cbl has been shown to negatively regulate tyrosine kinase receptors, including the stem cell factor receptor/c-Kit. Impaired recruitment of Cbl to c-Kit results in a deregulated positive signalling that eventually can contribute to carcinogenesis. Here, we present results showing that Cbl is activated by the SFKs (Src family kinases) and recruited to c-Kit in order to trigg
