We prove that the projection map of an orientable sphere bundle, over a compact Riemann surface, of any homotopy type can be realized as a harmonic morphism with totally geodesic fibres.

Popular Abstract in Swedish Eftersom mer än 80% av världens samlade energianvändning är beroende av förbränning i någon form är vidare kunskap om förbränningsprocessen viktig. Fortsatt effektivisering av förbränningsprocessen är idag högaktuell för uppbyggnad av framtidens mer miljövänliga energisystem och för utvecklingen utnyttjas omfattande diagnostikarbeten. Inom området anses diagnostik med hThe thesis deals with the further development of pure rotational coherent anti-Stokes Raman spectroscopy (RCARS) for improving the capabilities of gas phase thermometry. The main effort has been to make the technique more robust when employed under a wide range of temperatures and operational conditions. A primary aim has been to investigate the impact of collisional broadening on N2 RCARS thermom

Research has been pointing out that productivity in the building industry is stagnant and in some cases declining. Poor productivity of craftsmen is one of the causes of cost and time overruns on building projects. Productivity of labour is particularly important especially in developing countries where most of the building work is still carried out on manual basis. The objective of this research

Central venous catheters are used in various hospital wards. An anterior-posterior chest X-ray is usually obtained soon after cannulation to assess the location of the catheter tip. This prospective clinical study was designed to determine the radiographic catheter tip position after central venous cannulation by various routes, to identify clinical problems possibly associated with the use of mal

In this fast communication, we examine non-parametric data-adaptive spatial spectrum estimation using an array of sensors. We derive a forward-backward (FB) version of the recent spatial APES (SAPES) beamformer, and show that the SAPES algorithm is robust to the case of pairwise coherent sources. Numerical simulations indicate that the proposed FB version of SAPES offers higher resolution than the

Recently, plasma soluble urokinase plasminogen activator receptor (suPAR) has gained interest as a marker of cardiovascular risk. suPAR is released through the cleavage of urokinase plasminogen activator receptor (uPAR), which is found in monocytes, activated T-lymphocytes and endothelial cells, all involved in atherosclerosis. suPAR levels have been well studied in plasma, but no studies have foc

The authors have made a genome-wide analysis of mutations in Src homology 2 (SH2) domains associated with human disease. Disease-causing mutations have been detected in the SH2 domains of cytoplasmic signaling proteins Bruton tyrosine kinase (BTK), SH2D1A, Ras GTPase activating protein (RasGAP), ZAP-70, SHP-2, STAT1, STAT5B, and the p85alpha subunit of the PIP3. Mutations in the BTK, SH2D1A, ZAP70

Solid waste became one of the major environmental problems in Jordan, which has been aggravated over the past 15 years by the sharp increase in the volume of waste generated as well as qualitative changes in its composition. The challenges face solid waste management (SWM) in Jordan are numerous. Financial constraints, shortage of proper equipment and limited availability of trained and skilled ma
