Aims: The aim of the study was to screen the Enterobacteriaceae flora of meat for the presence of bacteria harbouring the Yersinia high-pathogenicity island (HPI). Methods and Results: Bacteria from 29 meat and 29 liver samples were isolated on violetred bile glucose agar. A total of 197 isolates were screened for the presence of the irp2 gene, encoded within the HPI, by PCR. One isolate that was

Objective: To discover a possible absorption and/or secretion of enterostatin into the circulating blood, as well as to compare the levels of circulating enterostatin after high-fat feeding and low-fat feeding. Research Methods and Procedures: Using a specific enzyme-linked immunosorbent assay, plasma enterostatin levels were determined after feeding a high-fat, a high-fat/sucrose, or a low-fat me

Lake Poopo, within the large Altiplano basin of Bolivia, is connected upstream to Lake Titicaca and downstream to the salares, the big salt fields. Small changes in precipitation and river inflows strongly affect the extent of the lake surface area. For times when there are no satellite images, it is difficult to determine the extent of the lake from observations. Water balance computations were p

Object: The aim of the present study was to investigate the pattern of non-fatal heroin overdoses for men and women in Sweden, a country with late onset of heroin use. Material: Subjects were recruited through the Syringe Programme and the Addiction Centre in Malmoe. A total of 149 subjects were interviewed, 108 men and 41 women. They were asked about their social situation, experienced and obser

Popular Abstract in Swedish I den här avhandlingen beskrivs några nyutvecklade tekniker för att mäta lungfunktion på såväl möss som människor. Varför behöver vi fler sätt att mäta hur lungorna fungerar? En anledning är att ju tidigare man upptäcker att något är fel med luftvägarna eller lungorna desto större är chansen att en behandling eller livsstilsförändring ska vara effektiv. Ett exempel är sIn this thesis we explore and further develop several techniques used in the animal laboratory as well as in the clinical setting. In particular, we expand the understanding and usefulness of plethysmographic techniques in small rodents. Study I shows that the pressure signal from an un-restrained plethysmograph (UP) depends largely on heating and humidification of the inhaled air. This brings int

Purpose: To evaluate a new letter matching visual acuity (VA) chart (the KM chart) for children aged 5-7 years, designed as a Monoyer-based chart, in order to obtain a better consistency between school and preschool VA recordings. Methods: Visual acuities were assessed using three methods: the HVOT, KM and Monoyer charts. Comparisons were made between the KM method versus the HVOT and Monoyer meth

Popular Abstract in Swedish Mycken möda har under de senaste årtiondena lagts ner på forskning om försurande utsläpp och dess skadliga effekter på skogar, vattendrag och människor. Kritiska belastningsgränser, i folkmun kallat "vad naturen tål", har tagits fram och använts i europeiska förhandlingar om utsläppbegränsningar. För skogsekosystem baseras de kritiska belastningsgränserna för försurandeAcidification caused by emissions of Nitrogen and Sulphur and associated adverse effects on forest ecosystems has been an issue on the political agenda for decades. Temporal aspects of soil acidification and/or recovery can be investigated using the soil chemistry model SAFE, a dynamic version of the steady-state model PROFILE used in critical loads assessment on the national level, e.g. for Swede

The aim of the study was to highlight the experiences and expectations of Swedish parents with respect to general parental education within child healthcare. Interviews were carried out with 25 parents who had attended education sessions. With a few exceptions the fathers did not take part, and those mothers who did comprised a relatively highly educated group; their views therefore predominate in

A kinetic model of the fermentative production of lactic acid from glucose by Lactococcus lactis ssp. lactis ATCC 19435 in whole-wheat flour has been developed. The model consists of terms for substrate and product inhibition as well as for the influence of pH and temperature. Experimental data from fermentation experiments under different physical conditions were used to fit and verify the model.

Jalil Haidar (född i Baghdad 1945, är sedan 1991 bosatt i Malmö)arbetar med ett sparsmakat språk befriat från äldre tiders retorik. Hans texter är täta och intensiva under en skenbar enkelhet. Bakom diktningen ligger ett engagemang i mänsklighetens och poesins vilkor, en strävan efter människans frihet och en bättre framtid.

We present a flexible and efficient program package written in C++, PROFASI, for simulating protein folding and aggregation. The systems are modeled using an all-atom description of the protein chains with only torsional degrees of freedom, and implicit water. The program package has a modular structure that makes the interaction potential easy to modify. The currently implemented potential is abl

The long-range, pheromone-mediated, flight behaviour of male moths under natural and mating disruption conditions was monitored by means of harmonic radar. Individual male turnip moths, Agrotis segetum (Denis & Schiffermüller) (Lepidoptera: Noctuidae), tagged with radar transponders, were released and tracked in plots with or without disruptive doses of sex pheromone. In addition, male attract

Dramatic swings in the North Atlantic oscillation (NAO) during the 1990s motivated the authors to build a statistical model of NAO impacts on hydropower production and energy markets in Scandinavia. Variation in the NAO index is shown to explain 55% of the variance of streamflow in Norway and up to 30% of the variance in Norway's hydropower output. It is also possible to identify the influence of

In a prospective study we tested the hypothesis that a cry from an infant can be used as part of an instrument to measure pain. Ten healthy newly born infants were subjected to painful stimuli on four occasions during their first year of life. The sound of the crying was analysed with regard to duration. With the help of a sound spectrogram, the fundamental frequencies of the first five crying sou

Popular Abstract in Swedish Inbyggda styrsystem finns idag överallt omkring oss. Moderna bilar, cd-spelare och mobiltelefoner är bara några exempel på produkter som inte skulle fungera utan datorbaserade reglersystem. Dock karaktäriseras dessa system ofta av begränsade beräkningsresurser, till följd av tillverkarnas behov att minimera produktionskostnaden. Samtidigt vill man införa mer och mer funThis thesis deals with methods for handling resource constraints in embedded control systems and real-time computing systems. By dynamic feedback-based resource scheduling it is possible to achieve adaptability andincreased performance for these systems. A feedback scheduling strategy is presented, which uses feedback from plant states to distribute computing resources optimally among a set of co
