The influence of adrenaline, nor-adrenaline, and acetylcholine on the electrocardiogram of the isolated perfused guinea-pig heart.
Bengt Johansson,Aado Vendsalu +1 more
TL;DR: The effect of increasingly large doses of adrenaline, nor-adrenaline, and acetylcholine on the electrocardiogram of the isolated, perfused guinea-pig heart was studied before and after administration of dibenamine and atropine.
Proceedings ArticleDOI
In-Cycle Closed Loop Control of the Fuel Injection on a 1-Cylinder Heavy Duty CI-Engine
TL;DR: In this article, a real-time combustion control system using an FPGA is presented, where the feedback used for the controller is the heat release, which is calculated by a proportional controller which is initiated after the start of the second injection.
Journal ArticleDOI
Exercise Training Adds Cardiometabolic Benefits of a Paleolithic Diet in Type 2 Diabetes Mellitus.
Julia Otten,Jonas Andersson,Jens Ståhl,Andreas Stomby,Ahmed Saleh,Maria Waling,Mats Ryberg,Jon Hauksson,Michael Svensson,Bengt Johansson,Tommy Olsson +10 more
TL;DR: Exercise training plus a Paleolithic diet reduced myocardial triglycerides levels and improved left ventricle remodeling in overweight/obese subjects with type 2 diabetes mellitus.
Proceedings ArticleDOI
Wavelet Analysis of In-Cylinder LDV Measurements and Correlation Against Heat-Release
TL;DR: In this paper, wavelet analysis was used to calculate turbulence and mean velocity levels for LDV measurements made in a four valve spark ignition engine and five different camshafts were tested, and they produced significantly different flow behaviour.
Journal ArticleDOI
Properties of liquid ionization chambers at LDR brachytherapy dose rates
TL;DR: Properties such as sensitivity, general recombination and reproducibility of liquid-filled parallel-plate ionization chambers for dosimetry in low-dose-rate brachytherapy radiation fields have been evaluated and an electric field strength of 300 kV m-1 was found to be optimal.
