Problems caused by dissolved organic matter (DOM) present in drinking water include its constituent compounds being precursors in the formation of disinfection by-products that pose risks to human health. The prediction of trihalomethanes (THM) formation is highly challenging due to a wide range of impacting factors, including the concentration and character of DOM, pH, temperature and the pres...

see [1, Thm. 6, p. 892], [6, Thm. 1, p. 288]. This theorem was a first impressive piece of evidence of the impact of distribution theory in its application to linear partial differential equations, and several different proofs of it were therefore devised in the subsequent years, see [3, Ch. X, and the historic notes in pp. 58, 59]. An elementary proof based on L2-theory was presented in [9]. F...

In this paper a general theory will be introduced that allows the description of a melodic surface i.e. a score-like representation of a melody in terms of local grouping, accentuation and metrical structures. Firstly, a formal model will be proposed that detects points of maximum local change that allow a listener to identify local perceptual boundaries in a melodic surface. The Local Botmdary...

The existence of trihalomethanes (THMs) in a drinking water plant of Nicaragua has been investigated in order to see whether the concentration exceeded the maximum contaminant level recommended by the environmental protection agency of the United States (USEPA) and the Nicaragua guidelines. The influence of pH, temperature, chlorine dose and contact time on the formation of THMs were studied. T...

The triple helix model (THM) studies the interactions between academia, industry, and government designed to promote entrepreneurship innovation in a knowledge-based society. This paper shows how agricultural extension works through THM for inclusive evaluate its effects on farmers. For this purpose, we analyze case of Cultiva UChile, technology transfer center led by University Chile that oper...

(THM) being used clinically as complementary medicine or alternative medicine is increasing. As well as this increase in popularity of THM in clinical situations, the co-administration of THM and drugs (manufactured chemicals) has also increased remarkably. Especially in cancer chemotherapy, it is true that the incidence of co-administration of THM and anticancer drugs is high. However, there i...

This study addresses the use of former gas storage facilities as short-term for renewable energy through power-to-gas (PtG) technology in Germany. Three test cases with coupled thermal-hydromechanical (THM) modelling were conducted to evaluate injection and production schedules. The operating rates controlled by upper lower limits wellbore pressure. maximum difference pore pressure effective st...
