nematicide, D-D(1,2-dichloropropane1,3dichloropropene), resulted in the greatest flowering with the controls giving the lowest (Table 2). The less effective nematicide, ethoprop (O-ethyl S,S-dipropyl phosphorodithioate), had an intermediate effect on flowering. In these tests, flowering was positively correlated with yield and negatively related to soil nematode populations and root-gall indice...

We introduce differentiable stacks and explain the relationship with Lie groupoids. Then we study S-bundles and S-gerbes over differentiable stacks. In particular, we establish the relationship between S-gerbes and groupoid S-central extensions. We define connections and curvings for groupoid S-central extensions extending the corresponding notions of Brylinski, Hitchin and Murray for S-gerbes ...

In this chapter we give a categorical definition of the integral cohomology ring of a stack. For quotient stacks [X/G] the categorical cohomology ring may be identified with the equivariant cohomology H∗ G(X). Identifying the stack cohomology ring with equivariant cohomology allows us to prove that the cohomology ring of a quotient Deligne-Mumford stack is rationally isomorphic to the cohomolog...

This paper discusses the modeling of the flue gas flow in industrial ducts and stacks using artificial neural networks (ANN’s). Based upon the individual velocity and other operating conditions, an ANN model has been developed for the measurement of the volume flow rate. The model has been validated by the experiment using a case-study power plant. The results have shown that the model can larg...

in this paper, the development of a new potassium carbonateon alumina support sorbent prepared byimpregnating k2co3 with an industrial grade of al2o3 support was investigated. the co2 capturecapacity was measured using real flue gas with 8% co2 and 12% h2o in a fixed-bed reactor at atemperature of 65 °c using breakthrough curves. the developed sorbent showed an adsorptioncapacity of 66.2 mgco2/...

To thoroughly study the extinguishing effect of a high-pressure water mist fire system when transformer occurs, 3D experimental model is established in this work by employing Fire Dynamics Simulator (FDS) software. More specifically, setting different parameters, process with presence both diverse ambient temperatures and sprinkler laying conditions simulated. In addition, employed implementati...
