A method to enhance weak two-neutron exit channels in heavy-ion induced fusion-evaporation reactions is demonstrated with a data set from the NORDBALL detector array, True two-neutron events are enhanced in relation to spurious events from cross-talk by a factor of 30. In the process the peak-to-background ratio in the coincident gamma-ray spectra improves more than 3 times.
The interaction between the dye cis-bis(4,4‘-dicarboxy-2,2‘-bipyridine)-bis(isothiocyanato)-ruthenium(II), Ru(dcbpyH2)2(NCS)2, and nanostructured ZnO was investigated by photoelectron spectroscopy (PES) using synchrotron radiation. The results are compared with those of nanostructured TiO2 sensitized with the same dye, which to date is the most efficient system for dye-sensitized photoelectrochemi
A mixed initial-boundary value problem for a nonlocal, hyperbolic equation is analyzed with respect to unique solubility and causality. The regularity of the step response and impulse response (the Green functions) is investigated, and a wave front theorem is proved. The problem arises, e.g., at time-varying, electromagnetic, plane wave excitation of stratified, temporally dispersive, bi-isotropic
OBJECTIVE: To investigate if the preventive measures taken to reduce the occupational exposure to asbestos have resulted in a decreased incidence of pleural mesothelioma in Sweden. METHODS: The incidence of pleural mesothelioma between 1958 and 1995 for birth cohorts born between 1885 and 1964 was investigated. The cases of pleural mesothelioma were identified through the Swedish Cancer Register.
Probabilistic analysis is the usual starting point for sociotechnical risk assessments aimed at deciding whether or not a particular risk is acceptable. However, the available probabilistic evidence is usually insufficient as a basis for such decisions, and so the assessment has to be supplemented by a judgemental process of a more deterministic nature. This concluding phase in decisionmaking is e
1 We studied the effects of a thromboxane A2 receptor (TP receptor) antagonist, ICI-192,605 (0.5mgkg-', i.v.) and a selective thromboxane (Tx) synthetase inhibitor, OKY-046 (30mgkg-1, i.v.), on airway responses induced by leukotriene D4 (LTD4; 0.2 nmol) or prostaglandin F2a, (PGF2,; 20 nmol) instilled via the airways route to anaesthetized guinea-pigs. For a comparison, airway responses to a TxA2-
In this paper, a control strategy for introducing enhanced biological phosphorus removal (EBPR) in an alternating plant designed for enhanced biological nitrogen removal (EBNR) is presented. Alternating aerobic and anaerobic conditions to promote EBPR are provided by controlling the phases of the operational cycle, instead of a separate anaerobic volume. By utilising the control schemes already bu
We present a multiplexed and internally calibrated quantitative reverse transcription-PCR (QRT-PCR) assay to detect human glandular kallikrein 2 (hK2) and prostate-specific antigen (PSA) transcripts in blood samples from healthy subjects and prostate cancer (PC) patients. The assay detected 50 copies of hK2 and PSA mRNA, and 1 PSA- and 10 hK2-expressing LNCaP cells in the presence of 2.5 x 10(6) P
Helicobacter pylori causes gastritis, peptic ulcer disease and gastric cancer. The microbe is found in the gastric mucus layer where a pH gradient ranging from acidic in the lumen to neutral at the cell surface is maintained. The aim of the present study was to investigate the effects of pH on H. pylori binding to gastric mucins from healthy individuals. At pH 3, all strains bound to the most char
An important step towards understanding the function of olivo-cerebellar climbing fibres must be to clarify what they signal. We suggest that climbing fibres projecting to paravermal cerebellum mediate highly integrated sensorimotor information derived from activity in spinal withdrawal reflex modules acting on single forelimb muscles. To test this hypothesis, cutaneous nociceptive receptive field
In many downstream processes microfiltration (MF) is used as the first step to separate the micro-organisms from the product-containing broth. The transmission of proteins through these MF membranes is of great importance, especially when a protein is the desired product. Usually, the largest fraction of the proteins retained in the membrane during the separation of micro-organisms is retained in

OBJECTIVE: To determine the impact of improved glycemic control on the development and progression of retinopathy after the institution of insulin therapy in patients with type 2 diabetes and to assess the relation to IGF-1 and hemostatic variables. RESEARCH DESIGN AND METHODS: In a prospective observational study, 45 type 2 diabetic patients were examined at baseline and 1, 3, 6, 12, and 24 month
Background: No strawberry allergen has so far been identified and characterized. Methods: Serum samples were collected from patients with a suggestive case history of adverse reactions to strawberry and other fruits. Extracts from fresh and frozen strawberries were analysed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE), Western blotting and mass spectrometry. Patient blo
A multi-proxy palaeoecological investigation including pollen, plant macrofossil, radiocarbon and sedimentological analyses, was performed on a small mountain lake in the Eastern Pyrenees. This has allowed the reconstruction of: ( 1) the vegetation history of the area based on five pollen diagrams and eight AMS(14)C dates and ( 2) the past lake-level changes, based on plant macrofossil, lithologic
