through this article, the distribution of air pollutants in tehran have been simulated based on wind patterns with and without the presence of synoptic by tapm (a meso-scale model). the simulation covers three horizontal resolution domains 30, 15 and 5 kilometers. the pollutants chosen for this are co and pm10 and wind data is 10 meter height level. the result has shown that the model simulated...

mean tropical state driving El Niño events for this analysis. Table 1 shows that knowledge of these quantities averaged over a 50-year window is not sufficient to determine the ENSO variability over the same window–developing more sophisticated metrics is a crucial goal of the proposed research. Nonetheless, simple lag-correlation analysis of NINO3 index and eastern Pacific thermocline depth (l...

Inhibition of Clostridium perfringens germination and outgrowth by salts of organic acids such as sodium lactate, sodium acetate, buffered sodium citrate and buffered sodium citrate supplemented with sodium diacetate was evaluated during continuous chilling of ground turkey. Turkey breast meat was injected with a brine-containing NaCl, potato starch and potassium tetra pyrophosphate to yield fi...

5) Two metrics were evaluated to determine trends over the past twenty years. The first metric is the Accumulated Cyclone Energy (ACE) index, which is the maximum sustained wind speed squared at six-hour intervals. ACE represents an approximation of the kinetic energy generated by a tropical cyclone. ACE correlates globally at 0.97 with Emanuel’s PDI index which is the wind speed cubed at six-h...

Abstract In this paper, the effect of microstructure a thick-walled rotor shaft for wind turbines on fracture toughness properties has been investigated. The relevant nodular cast iron grade EN-GJS-600-3 was processed using chill casting technology. Due to different solidification conditions over wall thickness, heterogeneous microstructures were formed. To illustrate influence gradient caused ...

ion links and index linksThe classes may form a structured hierarchy, in which the different levelscorrespond to the level of detail of the case descriptions. Riesbeck and Schank[5] distinguish two types of link between classes and their specializations:abstraction links and index links. A subclass connected by an abstraction linkprovides additional detail to its superclass,...

Chills (goose bumps) have been repeatedly associated with positive emotional peaks. Chills seem to be related to distinct musical structures and the reward system in the brain. A new approach that uses chills as indicators of individual emotional peaks is discussed. Chill reactions of 95 participants in response to seven music pieces were recorded. Subjective intensity as well as physiological ...
