Today the organization, the employers and employees must be more flexible and always adapt to a changing environment. The purpose of my study is to investigate how managers interact with their employees and how they use their leadership in an international organization. In order to achieve this I have conducted qualitative interviews with six managers within the same department and international c
In architecture and urban geography, discussions on repair, maintenance and adap5ve re-usehave emerged as a crucial intellectual terrain. Temporal aspects of how the urban fabric isused have also emerged as an issue worth theore5cal and empirical a=en5on. Latching ontothese themes, we will present work tracking the history of conten5on around the publiclyowned mee5ng and arts venue in Lund’s Peopl
The properties of the basic building blocks of nuclear matter, the quarks, and their interactions are not known in detail, largely because observations are complicated by the confinement of quarks in composite particles. New insights can be gained from the study of nuclear matter in a deconfined phase, like the form of matter that the Universe consited of early in its evolution according to the Bi
Traditionally the predominant generation has been large synchronous generators providing the system inertia. Nowadays when wind power and other non-synchronously connected units displaces this synchronous generation, the system inertia is reduced. Hence higher rate of change of frequency and larger frequency deviations are expected. This thesis deals with the impact on rate of change of frequency
Accurate calculation of energies for protein reactions is a hard problem. There are many reasons for wanting to calculate these energies, e.g. ligand design and the study of enzyme reactions. There are two major problem involved in these kinds of calculations. First, the large number of local minima in proteins introduces uncertainties when studying single structures. Second, the size of proteins
Since the metal oxide catalysts used in many chemical processes show very high selectivity for the products aimed at, both today and in the future, they play a key role in the environmentally and economically sustainable production of chemical intermediates. Two processes of this sort have been studied in the thesis: the ammoxidation of propane and propene over a Mo-V-Nb-Te-oxide catalyst and the
In generally accepted and applied flamelet combustion models, a turbulent flame is mainly assumed distorted by the large-scale turbulence eddies, whereas small-scale turbulence effects on the local flamelet structures are neglected. However, in a lot of industrial applications rather high turbulent intensities are often imposed, which induce turbulence scales at ranges smaller than the flame thick
This thesis is based on a study of Roman glass vessels found on non-Roman/native sites - chiefly of Roman Iron Age date (AD 0-400) - beyond Hadrian’s Wall in northern Britain. Roman glass vessels have been discovered on 60 sites in total, the majority of which are settlements of various types, and only a minor part are graves. As a consequence of this, the greater part of the material is strongly
The aim of this thesis was to describe the metabolism and to develope methods for biological monitoring for two organic acid anhydrides (OAAs), namely hexahydrophthalic anhydride (HHPA) and methylhexa-hydrophthalic anhydride (MHHPA). The OAAs are reactive, low molecular weight chemicals used in vast quantities in the industry. Many OAAs, including HHPA and MHHPA, are potent IgE sensitisers inducin
This thesis investigates the opportunity of wireless multi-gigabit per second communication at the millimeter-wave (mmW) frequencies around 60 GHz by using impulse radio and nanoelectronics. Today most wireless communication take place in the microwave region, where several different systems and applications are crowding the narrow-band channels. Complicated schemes are applied in order to avoid i
The present thesis is concerned with the theoretical study of x-ray photoemission spectra from clean and adsorbate-covered metal surfaces. The main tool is ab initio density functional (DFT) total energy calculations. The first part gives an overview of the theoretical treatment of x-ray photoemission with our present contributions highlighted, and an introduction to DFT theory and computational t
Prostate cancer is one of the major causes of cancer related deaths in men in Europe and the United States. In this doctoral thesis, radioimmunoimaging and -therapy of prostate cancer was investigated pre-clinically by targeting the human kallikrein-related peptidase 2 (hK2) with radiolabelled monoclonal antibodies. hK2 is an antigen that is over-expressed in prostatic neoplasms and is closely rel
Patients suffering from renal failure must remove extracellular water and waste products from their body in order to survive. One way of doing this is by treatment with peritoneal dialysis (PD). During PD treatment the abdominal cavity is filled and drained continuously with one to three liters of dialysis solution, often containing glucose, which act as an osmotic agent. Glucose creates a pressur
The old, world-wide phenomenon of playing board games has received little attention among scholars studying the ancient cultures. This thesis collects and analyses game-related material from Bronze Age Crete, defines the field of research and provides a framework with definitions and typologies. A further goal is to use the results of the analyses to extend beyond the archaeological material and e
Heat processing of vegetables involves the use of temperatures above the physiological limit which affect the cellular structures of the tissue and induce a series of events at cell level that will in turn be reflected in the transport properties of the tissue. One of the most important cellular structures from the mass transport point of view is the cell membrane since it represents the physical
In this thesis effects of liming on ectomycorrhiza have been studied in relation to effects on root colonization, fungal growth and nutrient uptake. In field experiments the effects of liming on ectomycorrhizal colonization of root tips were variable, possibly due to different soil types and climatic variations. However, a changed mycorrhizal community structure could be detected. Laboratory studi
Lymphocytes are important mediators of adaptive immune responses. Naive T lymphocytes circulate in the blood and lymph between different secondary lymphoid organs in search for their specific antigen. Upon activation, lymphocytes change their expression of adhesion molecules and chemokine receptors and become able to enter non-lymphoid tissues where they take part in fighting infections. Selective
The enzyme magnesium chelatase inserts magnesium into protoporphyrin IX (Proto) to produce to magnesium protoporphyrin IX, the first unique intermediate of the chlorophyll biosynthetic pathway. Magnesium chelatase is composed of three distinct proteins termed I (molecular weight ~40 kDa), D (~70 kDa) and H (~140 kDa). Defining the individual properties and structure of the magnesium chelatase comp
Based on the discovery of a new amino acid transport system in Langerhans cells (LC), various aspects concerning the L-dopa uptake mechanism into human epidermal LC and the energy metabolism of epidermis have been examined and subsequently characterised. The system lacks any characteristics of other described amino acid transport systems in other cell types. The Falck/Hillarp histofluorescence met
This thesis is a description of how knowledge of atomic physics can be used in a stellar spectrum analysis. Stellar investigations are spectroscopically performed based on wavelengths, intensities and spectral line structure. Properties such as isotopic shifts, hyperfine structure, Zeeman effect, line blending and spectral line broadening are investigated in stellar spectra to improve results of a
