The neutral–neutral reaction of the cyano radical, CN(X S), with ethylene, C2H4(X Ag), has been performed in a crossed molecular beams setup at two collision energies of 15.3 and 21.0 kJ mol to investigate the chemical reaction dynamics to form vinylcyanide, C2H3CN(X A8) under single collision conditions. Time-of-flight spectra and the laboratory angular distributions of the C3H3N products have...
Entrance, Exit and Exclusion: Labour Market Flows of Foreign-born Adults in Swedish ‘Divided Cities’
Entrance and exit effects for a viscoelastic liquid displacing a simple liquid through a contraction
This paper applies method of continuous-time random walks for pedestrian flow simulation. In the model, pedestrians can walk forward or backward and turn left or right if there is no block. Velocities of pedestrian flow moving forward or diffusing are dominated by coefficients. The waiting time preceding each jump is assumed to follow an exponential distribution. To solve the model, a second-or...
The rate coefficient for the important interstellar reaction between CN and has been calculated 22 as a function of temperature between 10 and 300 K. The potential surface for this reaction has been determined through ab initio quantum chemical techniques ; the potential exhibits no barrier in the entrance channel but does show a small exit channel barrier, which lies below the energy of reacta...
In Gram-negative bacteria, lipid modification of proteins is catalysed in a three-step pathway. Apolipoprotein N-acyl transferase (Lnt) catalyses the third step in this pathway, whereby it transfers an acyl chain from a phospholipid to the amine group of the N-terminal cysteine residue of the apolipoprotein. Here, we report the 2.6-Å crystal structure of Escherichia coli Lnt. This enzyme contai...
In this paper combined Brayton–Rankine cycle was mathematically simulated. In the Matlab program package an adequate numerical procedure has been developed to determine the maximum thermal efficiency of the combined cycle limited by the temperature of exhaust gases at the entrance of the gas turbine and the temperature of the condensation of water vapour in the steam condenser. Furthermore, add...
Electrical injuries are devastating and are difficult to manage due to the complexity of the tissue damage and physiological impacts. A paucity of literature exists which describes models for electrical injury. To date, those models have been used primarily to demonstrate thermal and morphological effects at the points of contact. Creating a more representative model for human injury and furthe...
