Exposure to moderate concentrations of tropospheric ozone impairs tree stomatal response to carbon dioxide

With rising concentrations of both atmospheric carbon dioxide (CO2) and tropospheric ozone (O-3), it is important to better understand the interacting effects of these two trace gases on plant physiology affecting land-atmosphere gas exchange. We investigated the effect of growth under elevated CO2 and O-3, singly and in combination, on the primary short-term stomatal response to CO2 concentration

Cultural identity? The Middle Neolithic Pitted Ware complex in southern Scandinavia

The aim of this short article is to question the archaeological classification of the Neolithic archaeological cultures, and to raise questions about how to understand the fragmentary material culture in terms of social agency and cultural expression. e settlement of Jonstorp in southern Sweden as a case of the south Scandinavian Pitted Ware complex presents theoretical and methodological implicat

QCD diffractive mechanism of exclusive W+W- pair production at high energies

We discuss new diffractive mechanism of central exclusive production of W+W- pairs in proton-proton collisions at the LHC. We include diagrams with intermediate virtual Higgs boson as well as quark box diagrams. Several observables related to this process are calculated. Predictions for the total cross section and differential distributions in W-boson rapidity and transverse momentum as well as WW

Sub-cycle control of attosecond pulse generation using two-colour laser fields

Strong field laser-matter interaction is intrinsically a sub-cycle phenomenon, which is clearly illustrated by the generation of attosecond pulses through the high-order harmonic process. Therefore, to control strong field processes the structure of the field driving the generation has to be controlled on a sub-cycle level. One approach is to use phase stabilized few-cycle driving pulses and vary

Measurement of visible cross sections in proton-lead collisions at root s(NN)=5.02 TeV in van der Meer scans with the ALICE detector

In 2013, the Large Hadron Collider provided proton-lead and lead-proton collisions at the center-of-mass energy per nucleon pair root s(NN) = 5.02 TeV. Van der Meer scans were performed for both configurations of colliding beams, and the cross section was measured for two reference processes, based on particle detection by the T0 and V0 detectors, with pseudo-rapidity coverage 4.6 < eta < 4.9, -3.

Writing Rights into Thailand's History with Photography

Photography is a recognized medium to spread information about atrocities and to raise awareness about human rights issues. Photography is also widely used by political actors and social move- ments to construct an image of themselves and their causes. The political potential of photography is closely connected to the role of the visual in the public. The language of photography is at the same tim

Laser-driven beams of fast ions, relativistic electrons and coherent x-ray photons

This thesis presents experimental results on the development and optimization of novel and highly compact sources of beams of fast ions, relativistic electrons and coherent x-rays, driven by intense laser-plasma interactions. The rapid development of high-power, short-pulse laser systems have made available peak powers reaching the petawatt regime and focused intensities reaching 10^21 W/cm2. Whe

Integral Identities for Passive Systems and Spherical Waves in Scattering and Antenna Problems

Popular Abstract in Swedish I avhandlingen presenteras nya teoretiska och experimentella metoder för att analysera spridning av elektromagnetiska vågor, framförallt med fokus på antenner och trådlös kommunikation. Oavsett det handlar om radio- och TV-sändningar, mobiltelefoni, trådlösa datornätverk, eller radar, så är antenner oumbärliga; de är nämligen länken mellan de elektromagnetiska vågorna oSum rules and physical limitations within electromagnetic theory and antenna theory have received significant attention in the last few years. However, the derivations are often relying on application specific and sometimes unsupported assumptions, and therefore a mathematically rigorous and generally applicable approach seems timely. Such an approach is presented in this thesis, along with exampl

Attitudes to health promotion interventions among patients in mental health services - differences in relation to socio-demographic, clinical and health-related variables

Background: Increasing evidence about the high social and economic costs of poor mental health has contributed to a growing recognition of the need for health promotion interventions in mental health services. In spite of this, little empirical research has been performed investigating patients' attitudes to health promotion interventions. Aims: The aim of the present study was to investigate diff

Novel Scabies Mite Serpins Inhibit the Three Pathways of the Human Complement System

Scabies is a parasitic infestation of the skin by the mite Sarcoptes scabiei that causes significant morbidity worldwide, in particular within socially disadvantaged populations. In order to identify mechanisms that enable the scabies mite to evade human immune defenses, we have studied molecules associated with proteolytic systems in the mite, including two novel scabies mite serine protease inhi

Stereoisomeric separation of derivatised 2-alkanols using gas chromatography – mass spectrometry: sex pheromone precursors found in pine sawfly species

Abstract in UndeterminedStereoisomers of long-chain secondary alcohols are used as sex pheromone precursors among pine sawflies and some species can be severe pine forest pests. To use their pheromone in environmentally friendly pest management, methods are needed that can determine the stereochemistry of the precursor alcohols. Combinations of 11 acid chloride derivatives and 10 GC columns were e

Experiences of physical activity during pregnancy in Danish nulliparous women with a physically active life before pregnancy. A qualitative study

Background: National guidelines recommend that healthy pregnant women take 30 minutes or more of moderate exercise a day. Most women reduce the level of physical activity during pregnancy but only a few studies of women's experiences of physical activity during pregnancy exist. The aim of the present study was to elucidate experiences and views of leisure time physical activity during pregnancy in

Included or excluded? The dual influences of the organisational field and organisational practices on new female academics

A number of measures have been taken by the society to ensure gender equality in higher education. Nevertheless, women still face great difficulties when pursuing an academic career. Our aim is to increase the understanding of how the society, conceptualised as the organisational field, interacts with organisational factors and personal actions as women try to establish themselves within academia.

Lean Service: A literature analysis and classification

The service sector in the USA accounts for 80% of gross domestic product. However, in spite of the pivotal role of the service sector in the US economy and its impact on daily life, the level of productivity in this sector has been much lower than that of the manufacturing area. This situation has been in existence for some time, but in the current context, there are growing external pressures to
