Excitation and emission polarization dependence of fluorescence intensity of single LH2 complexes from Rhodopseudomonas acidophila 10050 and Rhodobacter sphaeroides is reported. The results are presented as two-dimensional polarization plots and interpreted in terms of tilted light harvesting complexes indicating that sample preparation leads to partially oriented LH2 cylinders. An alternative exp
The diffusion of digital technologies has strongly affected the way scholars and researchers use and perceive the archaeological information detected during the field investigation process. Archaeologists are still only beginning to realize the full potential of these applications beyond the attraction of providing visually engaging documentation and focus on the analytical and interpretive power.
This chapter deals with the depictions of movement of violence in key narratives in Roman historiography.
In the humanitarian aid context, the availability of essential commodities in the right quantities and at the right time and place is crucial for the survival of beneficiaries. In order to avoid the risks associated with a limited supplier base, non-profit organizations are increasingly becoming aware of the need to diversify their supply base and to include the for profit, or corporate sector. Si
Popular Abstract in Swedish Mer än 75 % av energianvändningen i världen kommer idag från förbränning av fossila bränslen, biobränslen och avfall. Trots att alternativa energikällor är på framfart kommer förbränning stå för den största andelen av världens energianvändning även de kommande decennierna. Tyvärr medför förbränning flera negativa konsekvenser, såsom ökad koldioxidhalt i atmosfären och uLaser-induced incandescence, LII, is a laser-diagnostic technique that can be used to measure the volume fraction and the sizes of soot particles suspended in a gas, such as within a combustion process or in its exhausts. The technique is based on the facts that the time-decay of the radiation from laser-heated soot particles is directly related to the particle size in the probed volume, and that
Cigarette smoke exposure is well known to cause cardiovascular and airway diseases, both of which are leading causes of death and disability in the world. However, the molecular mechanisms that link cigarette smoke to cardiovascular and airway diseases are not fully understood. Vascular and airway hyper-reactivity plays an important role in the pathogenesis of cardiovascular and airway diseases. R
This book chapter examines the rapidly expansion of various neospiritual and science-like practices currently mobilized in late modern Swedish pursuits of identity, meaning, and health. The focus is on the emergence and marketing of new entrepreneurs who have established themselves as “therapists” or “coaches”, promoting personal development, and how they organize their own systems of training and
Book abstract: The book reviews recent observations of non-evolved and evolved binary populations in clusters and the field with special emphasis on statistical biases, incompleteness and distribution functions. Different binary types are considered: cataclysmic variables, super-soft X-ray sources, double degenerate binaries, Algol-type binaries, Be binaries, X-ray binaries, and Wolf-Rayet binarie
Atherosclerosis involves the formation of inflammatory arterial lesions and is one of the most common causes of death globally. It has been evident for more than 20 years that adaptive immunity regulates the magnitude of the atherogenic proinflammatory response. T cells may also influence the stability of the atherosclerotic lesion and thus the propensity for thrombus formation and the clinical ou
BACKGROUND: The aim of this study was to investigate, in an experimental survival model, the functional and morphologic results of lung transplantation using lungs from non-heart-beating donors. METHODS: Left lungs, topically cooled to 25 degrees C for 2 hours in situ after 5 minutes of circulatory arrest followed by 26 minutes of unsuccessful cardiopulmonary resuscitation, were transplanted into
OBJECTIVES: To standardise the colorimetric assay based on 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) for the rapid detection of rifampicin-resistant Mycobacterium tuberculosis in clinical practice and to evaluate the assay on a collection of 92 clinical isolates. DESIGN: The Bactec method was used as the reference method. Rifampicin was used for the susceptibility testing
Prior work on an engine combustion network Diesel fuel injector led to the conclusion that under Diesel engine conditions (combustion chamber pressure and temperature) the jet was transitionally supercritical; meaning that the core of the jet would be condensed liquid while the edge of the jet would be supercritical. We report initial experiments aimed at observing the thickened turbulent mixing l
Popular Abstract in Swedish Olyckor i järnvägssektorn kan ge upphov till katastrofala konsekvenser. I första hand kan människors liv och hälsa drabbas, men allvarliga konsekvenser kan även uppstå för samhället i stort. Detta beror på att järnvägssystemet, liksom en rad andra infrastruktursystem är väsentliga för att vårt moderna samhälle ska fungera. Under de senaste decennierna har dessa system bIn recent decades, the Swedish railway system has faced substantial deregulations. As a result, management of risk is often carried out in settings involving multiple stakeholders having various roles, mandates, and viewpoints on risk, and where no single stakeholder has the superior authority. In order to manage risks in this type of multi-actor setting, the traditional elements of risk assessmen
Type 1 diabetes involves the specific destruction of the pancreatic islet β-cells, eventually resulting in a complete dependency of exogenous insulin. The clinical onset of diabetes is preceded by the appearance of autoantibodies against β-cell antigens. The human leukocyte antigen (HLA) region is the single most important genetic determinant of Type 1 diabetes susceptibility, yet variability in t
This paper explores the bearing had by Aymara notions of spirit loss on contemporary indigenous discourses of colonialism and decolonization and discusses the dynamics of cross-fertilization between “traditional” curing practices and cosmology on the one hand and indigenous ethnopolitical activism and discourse on the other.
