High EGR rates combined with turbocharging has been identified as a promising way to increase the maximum load and efficiency of heavy duty spark ignition Natural Gas engines. With stoichiometric conditions a three way catalyst can be used which means that regulated emissions can be kept at very low levels. Most of the heavy duty NG engines are diesel engines which are converted for SI operation.

Abstract The objective of this investigation was to characterise the immunomodulatory or immunosuppressive effects of single drug treatment and the potential synergistic or additive effects of combined treatment with the focus on ciprofloxacin, thalidomide, mycophenolate mofetil, azathioprine, cyclophosphamide or leflunomide added to cyclosporin A (CyA). A rat cardiac transplant model was used to

The aim of the present doctoral thesis is to study and conceptualize juridification as a phenomenon. This aim comprises analyzing the theories through which juridification as an empirical development is interpreted. In this thesis juridification signifies displacements towards legal discourse. Juridification comes about when an issue that was previously dealt with within a cultural, ethical, polit

Popular Abstract in Swedish Det är känt sedan tidigare att komponenter från blodkärlets bindväv på olika sätt kan påverka sjukdomstillstånd som uppkommer i kärlväggen. En av dessa sjukdomar är ateroskleros (åderförkalkning), som genom sina följdsjukdomar (hjärtinfarkt, kärlkramp, stroke mm) utgör den vanligaste dödsorsaken i västvärlden. I den här avhandlingen studeras hur komponenter av kärlväggeThe composition of the vascular extracellular matrix (ECM) is altered during remodeling conditions such as atherosclerosis. The changed ECM regulates events that are important for the progression of disease including smooth muscle cell (SMC) behaviour and collagen fiber formation. The overall aim of this project was to relate changes in the composition of ECM in the arterial wall to processes duri

Sex pheromone communication and related physiological processes are regulated by circadian clock mechanisms in many moth species. This thesis includes studies of circadian rhythms in sexually relevant behaviours and communication in the Egyptian cotton leafworm Spodoptera littoralis, the turnip moth Agrotis segetum, the Indian meal moth Plodia interpunctella and the Mediterranean flour moth Ephest

In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration, is a frequent problem, which affects the result of the machining, and in particular, the surface finish. Tool life is also influenced by vibration. Noise in the working environment frequently occurs as a result of dynamic motion between the cutting tool and the workpiece. The research study inclu
