The paper discusses the so-called adverbial use of the wh-pronoun was (‘what’), which establishes a non-standard interrogative construction type in German. It argues that the adverbial use of was (‘what’) is based on the lexical properties of a categorically deficient pronoun was (‘what’), which bears a causal meaning. In addition, adverbial was (‘what’) differs from canonical argument was (‘wh...

AbstractPiping has been a documented cause of collapse multiple tailings dams, hydraulic structures and natural slopes. Important limitation the existing piping criteria for sloped ground i...

Throughout many parts of the world, cast iron pipe has been and continues to be used for utility piping (water sewage) gaseous media piping. Gray is known have a limited life in service but often left place beyond its reasonable life. Therefore, end then defined as rupture or crack subsequent leak, at an unpleasant time with results. The controlling mechanism involved dependent graphitic corros...

Nowadays, production control problems have been widely studied and a lot of valuable approaches are implemented. This talk addresses the problem of tracking the uncertain demand in case of uncertain production speeds. The uncertainties are described by deterministic inequalities and the performance is analyzed in the from of worst-case scenarios. First, simple mathematical models are introduced...

In addition to leachate and gas emission analysis, temperature variations in municipal solid waste landfills are routinely monitored for safety and health reasons, such as the increased production of biogas or the danger of spontaneous combustion phenomena if the temperature exceeds 70– 75◦C. The increasing constraints on greenhouse gas emissions and the convenience of fuel and heat recovery ha...
