An invertebrate nerve cell preparation, the lobster stretch receptor neuron, was investigated with respect to maintenance of its resting voltage, intracellular ion concentrations and excitability using voltage clamp technique and ion-selective microelectrodes. It was found that the resting voltage (-65 mV) of microelectrode impaled cells is caused by (a) a homogenous population of K+ channels whic
This chapter reflects on how experiences from aural-based musical practice, especially 'chordal thinking', may influence and facilitate pianists' interpretation of musical scores.
The acoustic field generated by flow unsteadiness in a model annular gas turbine (GT) combustion chamber is determined using a hybrid approach. In the flow solver the semi-compressible Navier-Stokes equations are resolved using LES as turbulence model. The acoustic solver is based on an inhomogeneous wave equation, where the instantaneous source terms are computed from the LES data in each time-in
Popular Abstract in Swedish I avhandlingen beskrivs och analyseras den svenska dagspressens hantering av doping och dopingöverträdelser inom internationell elitidrott. Artiklarna studeras med hjälp av följande tre frågeställningar: (1) Vad utmärker medieinnehållet om sport och doping? (2) Vilken bild av den sociala ordningen skymtar fram i detta mediematerial? (3) Vad berättar medieskandaler kringThe study analyses how the Swedish press dealt with doping and transgressions of the doping rules within international professional sports between 1996 and 2004. Three main research questions have been used in the research process: (1) What characterizes these media texts about sports and doping? (2) How is the social order pictured in the media texts? (3) What do media scandals about sport stars
In sociology, new institutionalists led the revival in interest in institutions in organizational theory and economic sociology by shifting the focus of causal reasoning from agent-centric studies of economic and organizational actors to the relationship connecting the firm with its institutional environment. We suggest a multilevel causal model incorporating the connection between the subinstitut

Respiratory minute volumes and instantaneous breath flow rates were measured in 8 subjects during treadmill work using (a) a particle filter respirator(Sundstroem SR200) and (b) a control breathing mask (Metamax I, Cortex). Work comprised five consecutive bouts of walking at 5 km/h with an increase in elevation of the treadmill by 5 % every 5 minutes. Minute ventilationincreased in a curvilinear m
A technique has been developed to measure the absolute OH concentration at atmospheric pressures by using a combination of direct absorption and laser-induced fluorescence (LIF) detection. The technique is independent of collisions, because it uses laser beams in a bi-directional configuration, thereby eliminating collisional quenching. The absolute OH concentration is measured spatially resolved
Iterative learning control (ILC) is used as a means for task execution of a time sub-optimal trajectory. The use of cascaded ILC procedures in a robot application is experimentally shown to drastically enlarge the region of convergence and efficiently compensate for unmodeled dynamics in the motion system.
We study the well known linear consensus algorithm by means of a LQ-type performance cost. We want to understand how the communication topology influences this algorithm. In order to do this, we recall the analogy between Markov Chains and electrical resistive networks. By exploiting this analogy, we are able to rewrite the performance cost as the average effective resistance on a suitable network
To obtain knowledge about combustion mechanisms operating in the ammoxidation of toluene, the formation of carbon oxides was studied over a Ti02(B)-supported vanadium oxide catalyst with monolayer loading. The partial pressures of reactants were varied and kinetic rate expressions, completely describing experimental data, were derived. A comparison of the expressions obtained with those for the fo
