Participant observation in logistics research: Experiences from an RFID implementation study
Purpose – The purpose is to describe the advantages, challenges and uncertainties of collecting and analyzing data using participant observation in logistics research. Design/methodology/approach – Experiences from a participant observation study of an interorganizational RFID implementation in an international environment are presented and reflected on. The RFID implementation included complex in

Structure of wobbling excitations in Lu-163
Using a many-particles plus rotor model, wobbling excitations built on top of a triaxial superdeformed band in Lu-163 are investigated. By extracting all parameters for the rotor from a mean field calculation a good correspondence with calculations based on the random-phase approximation is achieved.
Cost/benefit aspects on thromboprophylaxis
Several studies have shown thromboprophylaxis of any kind to be more cost-effective than no prophylaxis or general diagnostic surveillance and selective treatment. Little has been written on low molecular weight heparins from the cost-effectiveness point of view. This preliminary study shows low molecular weight heparin to be more cost-effective than standard low-dose heparin in most situations of
CONTECVET : A validated Users Manual for assessing the residual service life of concrete structures
This manual has been produced by the Swedish partners within the Innovation project CONTECVET (IN30902I). The chaper “General Introduction” is produced by the British partner BCA. The lead in drafting this report was taken by Lund Institute of Technology. The project has been co-ordinated at European level by BCA and at national level by GEOCISA in Spain and CBI in Sweden.
On the experimental validation of a non-linear shaft damping model
This paper presents an experimental validation of a proposed non-linear damping model for shaft torsional vibration studies, compared to the linear viscous damping model. Nine different shaft configurations were used. The deflection of each shaft exhibiting free vibration was measured for a period of one minute and the signal component at the natural frequency of torsion was found. The experiments
Sulfonylurea-Mediated Stimulation of Insulin Exocytosis via an ATP-Sensitive K(+) Channel--Independent Action.
Several reports indicate that hypoglycemic sulfonylureas augment Ca(2+)-dependent insulin secretion via mechanisms other than inhibition of the ATP-sensitive K(+) channel. The effect involves a 65-kd protein in the granule membrane and culminates in intragranular acidification. Lowering of granule pH is necessary for the insulin granule to gain release competence. Proton pumping into the granule i
Two chromones from Peperomia vulcanica
Two chromones: 5-hydroxy-2-(14'-(E)-nonadecenyl) chromone (1) and 5-hydroxy-2-[12'-(3",4"-methylenedioxyphenyl)dodecanyl] chromone (2), together with six known compounds have been isolated from Peperomia vulcanica Baker & C. H. Wright (Piperaceae). Their structures were determined by spectroscopic analysis including 2D NMR techniques.
Glucose Inhibition of Glucagon Secretion From Rat alpha-Cells Is Mediated by GABA Released From Neighboring beta-Cells.
Search for an LSP gluino at LEP with the DELPHI detector
In some supersymmetric models, the gluino ((g) over tilde) is predicted to be light and stable. In that case, it would hadronize to form R-hadrons. In these models, the missing energy signature of the lightest supersymmetric particle is no longer valid, even if R-parity is conserved. Therefore, such a gluino is not constrained by hadron collider results, which looked for the decay (g) over tilde -

Intracellular and interstitial expression of Helicobacter pylori virulence genes in gastric precancerous intestinal metaplasia and adenocarcinoma
Gastric intestinal metaplasia (IM) and gastric cancer are associated with Helicobacter pylori, but the bacterium often is undetectable in these lesions. To unravel this apparent paradox, IM, H. pylori presence, and the expression of H. pylori virulence genes were quantified concurrently using histologic testing, in situ hybridization, and immunohistochemistry. H. pylori was detected inside metapla
High-spin Spectroscopy of 63Ga and 65Ga
High-spin states in the nuclei Ga-63 and Ga-65 were studied following the reaction S-32 + Ca-40 at a reaction energy of 125 MeV and using the GASP gamma -ray spectrometer in combination with the ISIS charged-particle detector system. In addition to low-lying negative-parity states with single-particle character, rotational-like cascades built on the 9/2(+) and 19/2(-) states have been observed in

Shape coexistence at high spin in the N = Z+2 nucleus Se-70
The nucleus Se-70 was studied using the Ca-40(Ca-40, 2alpha2p) reaction at a beam energy of 185 MeV. Gamma rays were measured with the EUROBALL III spectrometer. The known positive-parity bands have been extended and one new band of positive parity and two of negative parity have been identified. These bands are interpreted in terms of the cranked Nilsson-Strutinsky approach. Calculations suggest
LD-isoenzym i uterusaspirat potentiell markör för endometriecancer. Utredning av postmenopausal blödning kan bli enklare och billigare
n diagnosing endometrial carcinoma in women with postmenopausal bleeding analysis of lactate dehydrogenase, LD, isoenzymes in uterine aspirates appeared to have 100 per cent sensitivity and negative predictive value combined with high specificity and positive predictive value. Determination of the LD-profile is suggested as a marker for endometrial carcinoma in women with postmenopausal bleeding.
Women With Irritable Bowel Syndrome and Their Perception of a Good Quality of Life.
Irritable bowel syndrome has a negative impact on a person's quality of life, but only a few existing studies have been based on patients' own perceptions. This study therefore aimed to collect information on the view of female patients with irritable bowel syndrome regarding what constitutes a good quality of life for them and to create a healthcare model for these patients. For the study, 30 wom
