The lean stability limit of a prototype syngas burner is investigated. The burner is a three sector system, consisting of a separate igniter, stabilizer and Main burner. The ignition sector, Rich-Pilot-Lean (RPL), can be operated with both rich or lean equivalence values, and serves to ignite the Pilot sector which stabilizes the Main combustion sector. The RPL and Main sectors are fully premixed,

The functional organization of the hindlimb withdrawal reflex system was studied in the rat. For the reflex pathway to each muscle, a "mirror-image" relationship was found between the spatial distribution of sensitivity within its cutaneous receptive field and the pattern of cutaneous unloading ensuing on muscle contraction. Thus, the withdrawal movement pattern ensuing on contraction in a muscle

Collagen-induced arthritis (CIA) is a T cell-dependent autoimmune disease that serves as an animal model for human rheumatoid arthritis. CIA can be induced in H-2q mice by a single immunization with the cartilage-specific protein type II collagen (CII). This study has focused on CII immunity and tolerance with respect to the interactions between antigen, antigen-presenting cells and T cells. CIA-r

When simulating homogenous charge compression ignition or HCCI using one-dimensional models it is important to have the right combustion parameters. When operating in HCCI the heat release parameters will have a high influence on the simulation result due to the rapid combustion rate, especially if the engine is turbocharged. In this paper an extensive testing data base is used for showing the com

Popular Abstract in Swedish Strålningsterapi är en viktig metod för att behandla många cancertyper och man söker konstant efter olika sätt att förbättra användningen av joniserande strålning vid behandling. Radiobiologisk forskning för cancerterapi söker att förbättra vår förståelse för hur joniserande strålning verkar på olika livsformer. Idag finns det många sätt att utröna en behandlings inverkFor the development of a Single–Ion Hit Facility (SIHF) for living cells irradiation at the Lund Ion Beam Analysis facility (LIBAF), newly developed pre-cell detectors have been investigated. These detectors can determine the number of ions reaching the sample. Central to the thesis is their fabrication and characterization. Two different detectors ’ Design A and Design B’ were fabricated with thi

Desalination can be a cost-effective way to produce fresh water and possibly electricity. The Gaza Strip has had a complex hydro-political situation for many years. Gaza is bordered by the Mediterranean in the west, by Israel in the north and east and by Egypt in the south. Water and electricity consumption in the Gaza Strip is expected to increase in the future due to the increasing population.

In market-driven requirements engineering for platform-based development of embedded systems such as mobile phones, it is crucial to market success to find the right balance among competing quality aspects (aka nonfunctional requirements). This paper presents a conceptual model that incorporates quality as a dimension in addition to the cost and value dimensions used in prioritisation approaches f

Various papers described mesh morphing techniques for computational biomechanics, but none of them provided a quantitative assessment of generality, robustness, automation, and accuracy in predicting strains. This study aims to quantitatively evaluate the performance of a novel mesh-morphing algorithm. A mesh-morphing algorithm based on radial-basis functions and on manual selection of correspondi

This thesis is based upon four original papers describing the characterisation of mantle cell lymphoma (MCL) tumours and cell lines in comparison with different populations of normal B cells. Gene expression profiling, which were used in the studies, has during recent years developed as an important tool in characterisation of different types of malignancies. In this thesis, the technique is used

Modern military multi-role combat aircrafts need an emergency power system (EPU) to maintain back-up power supply for all normal and degraded flight modes. The reason for this requirement is that modern combat aircrafts are designed with built-in relaxed or negative stability. Inability of the Flight Control System to perform continuous, corrective control surface actuation, due to loss of power

Class switch recombination (CSR) diversifies antibodies for productive immune responses while maintaining stability of the B-cell genome. Transcription at the immunoglobulin heavy chain (Igh) locus targets CSR-associated DNA damage and is promoted by the BRCT domain-containing PTIP (Pax transactivation domain-interacting protein). Although PTIP is a unique component of the mixed-lineage leukemia 3

BACKGROUND: /st>This study was undertaken to compare the effects of general anaesthesia (GA) and spinal anaesthesia (SA) on the need for postoperative hospitalization and early postoperative comfort in patients undergoing fast-track total knee arthroplasty (TKA). METHODS: /st>One hundred and twenty subjects were randomly allocated to receive either intrathecal bupivacaine (SA group) or GA with tar

Recent studies indicate that the urokinase system could have an important role in atherogenesis and plaque rupture. The relationships among the soluble urokinase plasminogen activator receptor (suPAR), carotid plaque, and incidence of ischemic stroke and coronary artery disease (CAD) events were studied in a prospective cohort.

Ensuring occupants' safety in building fires is one of the most important aspects for fire safety engineering. Many uncertainties are inevitably introduced when estimating the occupant safety level, due to the high complexity of fire dynamics and the human behaviour in fires. Safety factor methods are traditionally employed to deal with such uncertainties. This kind of methods is easy to apply but
