In this study stool samples from dyspeptic patients and healthy subjects were used for detection of specific Helicobacter pylori antigens and DNA by immunoenzymatic test (PPHpSA) and semi-nested PCR (ureA-PCR), respectively. The H. pylori status was estimated by invasive endoscopy-based rapid urease test and histology or noninvasive urea breath test (UBT), and by serology (ELISA, Western blot). Th

Calculated absorbed dose distributions from tangential irradiation of the breast have been compared with TLD measurements in a anthropomorfic body-shaped phantom which has gone through all phases of the radiation treatment planning cycle, including mapping of electron densities with a CT scanner, simulation of beam set-up and several treatments with an accelerator. The absorbed doses, measured in

UV-B treatment of thylakoid membranes or fractions derived from them accelerates the first rise (Fo---Fi phase) of variable fluorescence and slows down the second (Fi---Fm) rise. This can be observed for all membrane fractions but to different extents. The grana fraction is affected more by the UV-B treatment than are the intact thylakoids and the stroma lamella fraction. An exogenous electron acc

A search for events containing an isolated electron or muon and missing trans verse momentum produced in e(+/-)p collisions is performed with the H1 and ZEUS detectors at HERA. The data were taken in the period 1994-2007 and correspond to an integrated luminosity of 0.98 fb(-1). The observed event yields are in good overall agreement with the Standard Model prediction, which is dominated by single

The last decades have seen a strongly increasing use of computers for modeling larger and more complex systems. This has been made possible by a combination of increasing computer power and easy-to-use graphical modeling environments and libraries of components. An important class of systems are described by initial value problems for dynamical systems, and the increasing size and complexity imply

Popular Abstract in Swedish Kostfiber visar på gynnsamma effekter på blodsockersvar, inflammationsmarkörer och blodfetter utifrån tre humanstudier som genomfördes i detta arbete. I en av studierna analyserades blod och urin med metabolomik. Det är en metod där man analyserar alla små molekyler (metaboliter) som finns i provet med hjälp av vätskekromatografi kopplat till masspektrometri. Med hjälp It is well-known that dietary fibre can have a positive effect on the development of lifestyle-dependent diseases such as cardiovascular disease and type 2 diabetes. However, the effect may be different for different kinds of fibre and different sub-populations at risk. Therefore, the effects of three different kinds of fibre on postprandial and long-term response in healthy subjects were investig

We identified clusters of atypical sensory functioning adults with ASC by hierarchical cluster analysis. A new scale for commonly self-reported sensory reactivity was used as a measure. In a low frequency group (n = 37), all subscale scores were relatively low, in particular atypical sensory/motor reactivity. In the intermediate group (n = 17) hyperreactivity, sensory interests and sensory/motor i

In the context of Internet of Things (IoT), the research of this dissertation is concerned with the development of applications for end-user devices, i.e. devices through which the end-user directly interacts with systems. The complexity of such applications is partly due to network intricacies, and partly because GUI (Graphical User Interface) development is generally complicated and time consumi

The paper compares PM10 concentrations in railroad environments with EU air quality standards and characterizes particle concentrations and particle properties in relation to train traffic. The results show that PM10 concentrations in ground-level railroad environments do not exceed the EU directive 24-h limit value, while on the platforms of the two subterranean stations PM10 concentrations were

Sammanfattning Vid alla frågor om vårdnad, boende och umgänge ska principen om barnets bästa vara avgörande. Det framgår av 6 kap. 2a § föräldrabalken, FB. Relevant när frågan om ändring i vårdnaden uppstår är även bestämmelsen i 6 kap. 5 § andra stycket FB. Bestämmelsen har ändrats flera gånger under 2000-talet i syfte att stärka barnperspektivet. Av gällande lydelse framgår att föräldrars förmåg

Despite a recent interest among geographers and planners in experiments in and on the city, urban experimentation has yet to be examined critically. This thesis takes on the challenge by conceptualizing the place experiment as hermeneutical, transformative, co-creational and geographically bounded, and further by examining the strategic use of place experiments in municipal urban planning. The the

Skattelagstiftning styrs av principer, som ibland kan säga emot varandra och då behöva vägas mot varandra. I förarbeten redogör lagstiftaren för hur denna bedömning ser ut, och det är möjligt att genom förarbeten analysera vilka principer lagstiftaren behandlar, hur de behandlas och hur de vägs mot varandra. Det finns olika sätt att dela in skatterättsliga principer; ett sätt är att dela in dem i Tax law is governed by principles, that sometimes may contradict each other and then need to be weighed against each other. In preparatory works the lawmaker gives their account for how the assessment of principles looks like, and it’s possible through preparatory works to analyse which principles the lawmaker considers, how they’re considered, and how they’re weighed against each other. There are

A control system for pneumatic variable valve actuation has been designed, implemented and tested in a single cylinder test engine with valve actuators provided by Cargine Engineering AB. The design goal for the valve control system was to achieve valve lifts between 2 and 12 mm over an engine speed interval of 300 to 2500 rpm. The control system was developed using LabView and implemented on the

The ATP- and UTP-sensitive P2Y2 receptor which mediates both contractile and mitogenic effects has recently been shown to be upregulated in the synthetic phenotype of the vascular smooth muscle cell (VSMC). Using a competitive RT-PCR we demonstrate that the P2Y2 receptor mRNA is increased by fetal calf serum and other growth factors in a MAPKK-dependent way. This was confirmed at the functional le

A technology was developed to embed nm-sized metallic features in close vicinity to semiconductor heterostructures, which allows a direct integration of resonant tunneling diodes (RTD) inside the channel of permeable base transistor. A AlGaAs/InGaAs based RTD was grown by molecular beam epitaxy (MBE), with peak current density either 70 or 120 kA/cm². A fundamental oscillation frequency
