The sensitivity of the rat submaxillary gland was examined 3-4 weeks after either parasympathetic decentralization or sympathetic decentralization or denervation. The threshold doses for secretion of saliva of parasympathomimetic (methacholine) and sympathomimetic (noradrenaline, adrenaline, phenylephrine and isoprenaline) drugs were estimated and the amount of saliva secreted in response to supra

Patients attending the emergency room with acute asthma, participating in a study comparing salbutamol (albuterol in the United States) via a dry powder inhaler (Turbuhaler) with pressurized metered-dose inhaler (pMDI), were included in this 1-week follow-up study with the aim of assessing whether inhaled budesonide via Turbuhaler may be an alternative to prednisolone tablets after an acute asthma

A number of optically pure 1,3-diols have been synthesized and used as catalysts in the asymmetric addition of diethylzinc to aromatic aldehydes. Enantiomeric excesses of up to 92% of (R)-1-phenylpropan-1-ol were obtained with anisylbicyclo[2.2.2] octanediol (14) as a catalyst. Using 2-picolylbicyclo[ 2.2.2] ocatanediol (16) as the catalyst resulted in a reversal of the stereoselectivity, yielding

We present new synthetic broad-band photometric colors for late-type giants based on synthetic spectra calculated with the PHOENIX model atmosphere code. The grid covers effective temperatures T-eff = 3000... 5000 K, gravities log g = - 0.5... + 3.5, and metallicities [M/H] = + 0.5... - 4.0. We show that individual broad-band photometric colors are strongly affected by model parameters such as mol

Popular Abstract in Swedish I denna avhandling studeras skolsituationen för elever med båda föräldrarna födda utomlands. Samband mellan elevernas bakgrund, övriga faktorer som i tidigare forskning visat sig betydelsefulla och skolresultat identifieras och analyseras. Studien utgår från de data som insamlades inom ramen för "Det nationella programmet för utvärdering", som genomfördes 1992. UtvärderThe overall purpose of this study was to provide knowledge about the school situation of pupils in Sweden whose parents were both born abroad. The connections between the pupils’ background, other factors shown to be significant in earlier studies, and school results have been identified and analysed. The study was based on the data compiled as part of the National Programme of Evaluation, which w

A direct search has been made for magnetic monopoles produced in e(+)p collisions at a centre of mass energy of 300 GeV at HERA. The beam pipe surrounding the interaction region in 1995-1997 was investigated using a SQUID magnetometer to look for stopped magnetic monopoles. During this time an integrated luminosity of 62 pb(-1) was delivered. No magnetic monopoles were observed and charge and mass

Screening women for lower genital tract infection with Chlamydia trachomatis is important in the prevention of pelvic inflammatory disease, ectopic pregnancy and infertility. This systematic review aims to state clearly which of the available diagnostic tests for the detection of C. trachomatis would be most effective in terms of clinical effectiveness. The review included all studies published fr

PURPOSE: A spin-echo diffusion-sensitized pulse sequence using high gradients (23 mT/m) is introduced. MATERIAL AND METHODS: In order to minimize motion artefacts, velocity-compensating gradients, ECG-triggering and post-processing with phase correction and raw data averaging using navigator echoes was performed. The in vitro ratio of diffusion coefficients for water and acetone was determined and

As part of a project aimed at developing models for photosystem II (PSII) in green plants, we have prepared a series of model compounds (7, 8, and 13). In these compounds, a photosensitizer, ruthenium(II) tris(bipyridyl) complex (to mimic the function of P-680 in PSII), was covalently linked to a manganese(II) ion through different bridging ligands. The structures of the compounds were characteriz

Most of the world's energy generation is based on fossil fuels such as coal and oil, which already today but even more in the future, will cause various problems. One issue is their limited availability, which stands in conflict to the increasing global energy consumption. Another problem is the carbon dioxide generation caused by burning fossil fuels for energy production, and is thought to be on

This paper describes a methodology for measuring theological flow properties in-line, in real-time, based on simultaneous measurements of velocity profiles using an ultrasound velocity profiling (UVP) technique with pressure difference (PD) technology. The methodology allows measurements that are rapid, non-destructive and non-invasive and has several advantages over methods presented previously.
