Measurements of the stoichiometry of silicon nitride films as a function of the number of incident ions using heavy ion elastic recoil detection (ERD) show that beam-induced nitrogen depletion depends on the projectile species. the beam energy, and the initial stoichiometry. A threshold stoichiometry exists in the range 1.3 > N/Si greater than or equal to 1, below which the films are stable agains

Background Smoking is known to cause chronic inflammatory changes in the bronchi and to contribute to airway hyper-reactivity, such as in bronchial asthma. To study the effect of smoking on the endothelin system in rat airways, bronchial segments were exposed to DMSO-soluble smoking particles (DSP) from cigarette smoke, to nicotine and to DMSO, respectively. Methods Isolated rat bronchial segment

Denna rapport i Kyrkohistorisk årsskrift, som jag sedan 2001 redigerar, redovisar LUKA:s utvidgade verksamhet med årliga arrangemang som LUKA-dagen i mars och Arkivens dag i november, skriftutgivning (Bibliotheca Historico-Ecclesiastica Lundensis samt Meddelanden från Kyrkohistoriska arkivet i Lund. Ny följd), nya frågelistor till alla Svenska kyrkans församlingar, till församlingarna i vissa stif

Aim: Palivizumab (Synagis(R)(R)) was registered in Sweden in 1999 for prophylaxis against respiratory syncytial virus (RSV) in premature infants. The high costs and the limited knowledge of the efficacy of this substance have led to debate about how and when it should be used. National guidelines for the use of palivizumab in Sweden were constructed in the year 2000. The aim of this study was to e

This paper reviews decision support methodologies that can be applied to treatment plants. Case studies of decision support systems (DSS) that have been developed and used or trialled are presented below. These include rule-based systems and systems based on digraphs of cause-and-effect relationships. Detection examples on real plant data are presented, in one case using direct measurements and si

In the beginning of 1990s preparations were underway in Sweden to enact a law aimed at making accounting on personnel in the annual reports compulsory. An official investigation resulted in a special report on how to design and report on it. The expectations and the discussions that followed resulted in considerable voluntary implementation of “personnel economics reports” or “human resources acco

A cheap value-added product, the protein fraction of barley spent grains is proposed as a source of a potential and economical cultivation medium. We showed that medium composed of protein fraction extract allows the isolation of actinobacteria, especially Streptomyces, from soil samples, and enhances the sporulation. It was used for the screening and production of the biologically active substanc

The relationships between, on the one hand, burnout, empathy and sense of cohoerence (SOC) and, on the other, personality traits were investigated, together with the effects of systematic clinical supervision on these phenomena among Swedish district nurses. The results in the supervisory group (n = 21) were compared with those of a comparison group (n = 12) in a quasi-experimental design. Persona

By providing the Lund Model fragmentation process with a quantum-mechanical framework we extend the results of previous work to situations where there are very many identical bosons. We investigate the features of the weight distributions in some detail and in particular exhibit three-particle BE-correlations, the influence on the rho-spectrum and the difference between charged and neutral pion co

High resolution electron energy loss spectroscopy has been used to determine how NH3 adsorbs on the Si(100)2 × 1 surface at 300 K. We find that the NH3 molecules dissociate into NH2 and H on adsorption. Combination bands, overtones and double losses for the Si---NH2 group are observed. An anneal to 800 K is sufficient to dissociate the adsorbed NH2 groups while the majority of the Si---H bonds rem

The protochlorophyll(ide) present in primary roots of dark-grown corn (Zea mays) seedlings has an in vivo absorption maximum at 634 nm. Red light converts the pigment to chlorophyll(ide) a with an absorption maximum at 675 nm.

In a replicated field experiment we studied the effects of natural densities of two exotic consumers, the predatory and herbivorous signal crayfish (Pacifastacus leniusculus) and the predatory rainbow trout (Oncorhynchus mykiss), on multiple trophic levels of a pond community. The goals were to: (1) determine the individual and combined effects of predators on macroinvertebrates, macrophytes, and

The accuracy and precision of holographic interferometry as a method to measure diffusion coefficients in gels are investigated both experimentally and theoretically. The standard deviations in the experimentally determined diffusion coefficient for ethanol in 4% (w/v) agarose gel were 3.3% for diffusion into the gel and 6.1% for diffusion out of the gel. These are in good agreement with the stand

Cytogenetic studies of Ph-positive leukemic patients and their parents have indicated that chromosome 22 involved in the formation of the t(9;22) is of maternal origin, whereas chromosome 9 is preferentially of paternal origin. These data have suggested that the two genes BCR and ABL, which become fused through the translocation, might be imprinted, ie expressed in a parental-specific manner. Rece
