The bicyclic keto-alcohol (1S,4R,6S)-bicyclo[2.2.2]octan-6-ol-2-one, (+)-3, self-assembles in the solid state through hydrogen bonds between the alcohol and the carbonyl groups creating supramolecular helices, without the aid of other forces such as pi-pi interactions to stabilise the superstructure. Furthermore, the bicyclic compound (4) although structurally quite different, in relation to (+)-3
A comprehensive set of 4He(,n) absolute cross-section measurements was performed at MAX-lab in Lund, Sweden. Tagged photons from 23
Abstract: Purpose – While the importance of measuring customer satisfaction levels is well established, less research exists on how organizations operationalize such knowledge. The purpose of this paper is to describe an action research (AR) case study resulting in a workshop model to operationalize the concept of value. The model facilitates organizational learning and mindset changes in order to
Popular Abstract in Swedish "Det var en gång en kung som aldrig gjorde något bra för sina undersåtar. Han gjorde faktiskt aldrig nånting. Det enda han ville var att äta och dricka, och berusa sig tillsammans med sitt hov. Under tiden svalt folket ihjäl." Anna frågar: varför kunde inte människorna äta hemma? "Tyst nu, och lyssna på fortsättningen…" (citat ur avhandlingen) Martina Camparts forskniAbstract The point of departure for this study is the author's experience as educator in a residential home for children (age 6-14) with social-emotional problems, in Italy, between 1980 and 1989. One important element of the pedagogical approach was the use of narratives (personal, of others, of fiction) to prompt children's interest/ motivation to reflect about issues of personal concern. A conv
In Escherichia coli the osmoprotective compound glycine betaine is produced from choline by two enzymes; choline dehydrogenase (CDH) oxidizes choline to betaine aldehyde and then further on to glycine betaine, while betaine aldehyde dehydrogenase (BADH) facilitates the conversion of betaine aldehyde to glycine betaine. To evaluate the importance of BADH, a BADH/CDH fusion enzyme was constructed an
In a search for β-delayed charged particles from 14Be we have obtained an upper limit on β-delayed greek small letter alpha particles, B(βgreek small letter alpha)<1.2×10−4, and found evidence for β-delayed tritons at intensity of 6×10−5
Popular Abstract in Swedish Demens är ingen enhetlig sjukdom utan ett syndrom dvs en beteckning på en grupp symtom, som beskriver en långvarig försämring av hjärnans psykiska funktioner. Demens kan ha olika klinik profil och orsakas av olika skador och sjukdomar. Den vanligaste demenssjukdomen är Alzheimers sjukdom. Kring denna sjukdom finns mycket forskning gjord. Vaskulär demens är den näst vanlDuring the period (1976-1995) a total of 175 consecutive patients (m 88/f 87) with neuropathologically verified vascular dementia (VaD) were examined. 22 patients with pure Alzheimer's Disease (AD) were also studied. All patients were diagnosed and followed at the Department of Psychogeriatrics (Lund University Hospital). The neuropathological examination revealed VaD, sometimes with additional co

Background: There is a shortage of reports on what potential recipients of implantable cardioverter-defibrillators ( ICDs) need to be informed about and what role they can and want to play in the decision-making process when it comes to whether or not to implant an ICD. Aims: To explore how patients with heart failure and previous episodes of malignant arrhythmia experience and view their role in
Of the sensory nervous system associated signal substances it is only calcitonin generelated peptide (CGRP) that is reliably associated with the degree of pain in the acute attacks of primary headaches. The treatment with triptans alleviates both the pain and the associated CGRP release, putatively via a presynaptic effect on the sensory nerves. The studies of opoids and other sensory neuropeptide

We have performed experiments where DKDP has been irradiated by short (100 fs), laser pulses. Subsequently X-ray pulses with a duration of 100 ps were used as a probe. Time-resolved X-ray diffraction enables monitoring of the transitions between the paraelectric and ferroelectric phases. By recording the intensity of a peak only present in the paraelectric phase, we observe indications of a phase-
Aryl iodides are important synthetic intermediates that can be transformed into tritium labelled compounds by metal-mediated hydrodehalogenation and also react in a number of important synthetic transformations. We present ICI/ln(OTf)(3) as a new reagent combination for mild iodination, suitable for acid-sensitive substrates such as carbohydrates. (c) 2005 Elsevier Ltd. All rights reserved.
By using the density matrix theory of interaction between light and matter, and relevant parameter calculations of the relaxation rate, the dipole matrix elements and the ion density for a three-level ladder model, we have discussed theoretically the possibility to realize electromagnetically induced transparency (EIT) in Er3+:YA1O(3) crystal.

Dijet cross sections as functions of several jet observables are measured in photoproduction using the HI detector at HERA. The data sample comprises e(+)p data with an integrated luminosity of 319 pb(-1). Jets are selected using the inclusive k(perpendicular to) algorithm with a minimum transverse energy of 25 GeV for the leading jet. The phase space covers longitudinal proton momentum fraction x
