Using in situ surface-sensitive electron microscopy performed in real time, we show that the dynamics of micron-sized Ga droplets on Ga P(111) can be manipulated locally using Au nanoparticles. Detailed measurements of structure and dynamics of the surface from microns to atomic scale are done using both surface electron and scanning probe microscopies. Imaging is done simultaneously on areas with

Survival after childhood cancer has improved substantially over recent decades. Although cancer in childhood is rare increasingly effective treatments have led to a growing number of long-term survivors. It is estimated that there are between 300,000 and 500,000 childhood cancer survivors in Europe. Such good survival prospects raise important questions relating to late effects of treatment for ca

This article studies the Kyoto Protocol’s CDM as an example of hybrid governance, involving both public and private actors, and uses the concept of agency to explore the influence of public and private actors in the governance of the CDM over time. Even though public actors formally govern the CDM, the delegation of project implementation and supervision to private companies has created ample oppo

Glacial rebound modelling, to establish constraints on past ice sheets from the observational evidence of palaeo-shoreline elevations, is well established for the post- Last Glacial Maximum (post-LGM) period, for which the observational evidence is relatively abundant and well distributed spatially and in time. This is particularly the case for Scandinavia. For the earlier part of the glacial cycl

Due to its effects on the atmospheric lifetime of methane, the burdens of tropospheric ozone and growth of secondary organic aerosol, isoprene is central among the biogenic compounds that need to be taken into account for assessment of anthropogenic air pollution-climate change interactions. Lack of process-understanding regarding leaf isoprene production as well as of suitable observations to con

The structure, formation, and evolution of the Milky Way bulge is a matter of debate. Important diagnostics for discriminating between models of bulge formation and evolution include alpha-abundance trends with metallicity, and spatial abundance and metallicity gradients. Due to the severe optical extinction in the inner Bulge region, only a few detailed investigations of this region have been per

The morphological matrix is an important element of the engineering design methodology and is present in many textbooks. This method originally aimed at generating an exhaustive set of solutions for a given problem, by decomposing it into subproblems, finding solutions to each subproblem, and combining them. One issue associated with the morphological matrix has been the necessity to deal with the

Gold-bearing pyrite ores are refractory and must be pre-treated to break down the sulphides by oxidation. This is done usually by roasting, bacterial oxidation and smelting. Moreover, ores with high sulphur content require pre-treatment to prevent excessive chlorine consumption, an important source of pollution. The pyrite waste created in mining operation presents serious problems on the environm

Popular Abstract in Swedish Sår som inte läker utgör ett betydande problem för dem som drabbas och för sjukvården i stort. Utebliven eller defekt läkning är ofta ett led i en bakomliggande sjukdom som exempelvis diabetes, förlamningstillstånd eller olika bindvävs- och kärlsjukdomar. Förutom en mycket stor ekonomisk belastning för sjukvården, så innebär det ett stort fysiskt och psykiskt lidande föBackground: A large number of different wound coverings have been used in order to improve the wound microenvironment, and thus accelerate repair. Since almost two centuries, clinicians and researchers have developed techniques for skin transplantation. In the past several decades, growth factors have been used as tools for accelerating and modifying skin wound repair. The experimental work in thi

Investigating the vadose zone, the physics behind the temporal and spatial instabilities of flow (in unsaturated media) is still of question. Although chaotic approaches have been widely employed for identifying different surface hydrology processes, such as rainfall, runoff, lake volume, etc., they were not applied for subsurface systems as much. On this ground, the present study attempts to inve

After centuries of feudalism, the establishment of the Japanese parliament (the Diet) in 1890 marked a major turning point in Japanese history. Before 1890, politics as a subject of discussion was confined, more or less, to peer groups in Japanese society. In addition, at certain periods, movements promoting the spread of ideas were strictly controlled or even prohibited. Then came the new Diet,

This licentiate thesis examines the development of internationalization of production in Kazakhstan and its economic implications over the period 1991-2010. The main objectives of the thesis are to investigate the role of foreign investment and TNCs in the economic growth of Kazakhstan since its independence in 1991 and onward, to explore the motives that foreign enterprises have for investing in

Popular Abstract in Swedish Att gifta sig eller att vara med om en olycka är emotionella händelser som skapar våra mest livfulla och detaljerade minnen. Sådana minnen av händelser i tid och rum kallas generellt episodiska minnen. De flesta människor minns till exempel nästan exakt var de var när de hörde talas om terrorattackerna i New York 2001. De flesta av oss har nog redan glömt vad som hände The investigation of memory distortions provides insights into how memory normally works. Adopting a cognitive neuroscience perspective, the present thesis aimed at investigating memory distortions and the neural correlates of processes contributing to successful control of memory interference in healthy participants. All studies employed variations of the modified continuous recognition task. In

Popular Abstract in Swedish Denna avhandling handlar om en grupp narkotikamissbrukare som gjort självmordsförsök. Såväl självmord som självmordsförsök är betydligt vanligare bland narkotikamissbrukare jämfört med totalbefolkningen. Bland vårdade narkotikamissbrukare är det mellan 19 till 47 procent som gjort självmordsförsök. Det höga självmordsförsökstalet bland narkotikamissbrukare förklaras oftThe aim of this thesis is to describe suicide attempts in a group of drug abusers who previously had received treatment of their addiction. Another aim is to interpret and analyse the life situations that the individual associates with the suicide attempt. The dissertation is based on interviews conducted on two occasions with 92 drug abusers, 62 men and 30 women. The majority of the drug abusers

Background: The clinical management of patients with coronary artery disease (CAD) often involves a complex assessment of the extent and severity of changes in left ventricular (LV) myocardial perfusion, function and viability. We aimed to explore the feasibility of integrative quantitative representation of LV perfusion, function and viability in adjacent polar plots. In order to assess the clini

Studies were conducted to elucidate co-receptor spectrum and function of the inflammatory receptor, CMKLR1/ChemR23, which was recently identified as the receptor for the cystatin-like chemoattractant, TIG2, also named chemerin. An infection model was applied based on stably transfiected NP-2.CD4 host cells expressing various co-receptor constructs and exposed to panels of HIV-1, HIV-2 and SIV prim

In order to improve the surface quality of TC4 titanium alloy parts, the effect of grinding parameters on surface integrity must be known. In this research, an experimental analysis has been conducted to understand the effect of grinding parameters, including cutting velocity, feed rate, grinding depth and abrasive size, on material removal and surface integrity. Before conducting experiment, test

We present a study of high-order-harmonic generation (HHG) assisted by extreme ultraviolet (XUV) attosecond pulses, which can lead to the excitation of inner-shell electrons and the generation of a second HHG plateau. With the treatment of a one-dimensional model of krypton, based on time-dependent configuration interaction singles (TDCIS) of an effective two-electron system, we show that the XUV-

In this letter, the fading statistics of wireless channels in high-speed railway cutting scenarios are characterized based on measurements. A multiple scattering model called second-order scattering fading (SOSF) is used to model the small-scale fading considering the influence of cuttings and bridges. The SOSF model can offer the possibility of analytical estimation for different fading severitie

Diagnostic reference levels are the main and the most effective tools of optimization of the radiation protection of patients from medical exposure. Diagnostic reference levels should be established based on theresults of dedicated dose surveys, allowing evaluating typical patient dose distributions in a selected dose quantity for the selected X-ray examinations. The aim of the current study was t
