We study dissipative properties of the motion of a slow nuclear collective variable weakly coupled to a complex quantum environment formed by the fast nucleonic degrees of freedom. The fast quantum mechanical subsystem is treated within the random matrix approach, where the complexity of the nucleonic degrees of freedom's motion can be changed by a parameter from regular to fully chaotic.

OBJECTIVE—Glucagon-like peptide 1 (GLP-1) is an incretin that augments insulin secretion after meal intake and is developed for treatment of type 2 diabetes. As a novel therapeutic agent, characteristics of its β-cell effects are important to establish. Previously, β-cell effects of GLP-1 have been characterized in humans during graded intravenous infusions of glucose, whereas its effects after mo

To increase the pace of development and deployment of new services and applications in telecommunication networks, new service architectures have been proposed. Parlay/OSA is one of the proposals that has aroused most attention. By providing network functionality via Application Program Interfaces (APIs), Parlay/OSA facilitates creation of telecommunication services and applications for independen

Oxidation of coproporphyrinogen III to coproporphyrin III is found in extracts of Escherichia coli cells containing the Bacillus subtilis HemY protein (M. Hansson and L. Hederstedt, J. Bacteriol. 176, 5962-5970). We have analysed whether this activity is due to the heterologous expression system, since it in vivo would lead to disruption of the heme biosynthetic pathway. B. subtilis hemY was fused

Culture filtrates of the nematophagous fungi Verticillium chlamydosporium and V. suchlasporium growing on colloidal chitin showed increasing chitinolytic activity and production of two (32- and 43-kDa) main proteins. Maximum activity was found 18-20 days after inoculation, but V. suchlasporium always displayed higher activity. Zymography of such filtrates on carboxymethyl-chitin-Remazol brilliant

Recent studies of semen quality in men from the general population gave rise to the hypothesis of an East-West gradient in semen quality in the Nordic-Baltic area, with the highest sperm counts in Estonia, Lithuania and Finland, and the lowest in Denmark (30% difference in mean concentration). Genetic, lifestyle-related and environmental factors - alone or in combination - were suggested to be res

We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLID experiment using a polarised beam at SLC. The measurements include cross-sections, for

We are reporting about a scintillating fibre tracking detector which is proposed for the precise determination of the absolute luminosity of the CERN LHC at interaction point 1 where the ATLAS experiment is located. The detector needs to track protons elastically scattered under mu rad angles in direct vicinity to the LHC beam. It is based on square shaped scintillating plastic fibres read out by

Gonyostomum semen (Raphidophyceae) is today one of the most common flagellates in humic lakes ill Sweden and appears regularly in 30% of these lakes. The first mass development of this alga was recorded in 1948 in Lake Helgasjon, South Sweden. In this paper the life cycle of Gonyostomum is described for the first time. During the winter Gonyostomum survived as resting cysts on the surface of the b

Recent advances in technology, including computerized analysis, have renewed interest in pharyngeal manometry. Simultaneous fluoroscopy and videography have been recommended by many authors. This article reviews the history of pharyngeal manometry and highlights some of the technical difficulties involved. We also report the current status of the simultaneous technique and summarize our own result

The aim of this article is to contribute to the development of the domain analytical approach by using tools from the theory of professions. This is accomplished by showing how the symbolic values of professional information can create, sustain, and alter professional interests, power relations, and occupational identities. By taking this approach, the importance of considering the issues of power

The radiobiological effect of intracellularly localised radionuclides emitting low energy electrons (Auger electrons) has received much attention. Most in vivo studies reported have been performed in the mouse testis. We have investigated the rat testis as an in vivo radiobiological model, with sperm-head survival, testis weight loss and also alteration in the blood plasma hormone levels of FSH an
