background: chlorophenols are classified as priority toxic pollutants. these acidic organic compounds present a serious potential hazard for human health and aquatic life. chlorophenols accumulate in water, soil and air due to high stability, and impart an unpleasant taste and odor to drinking water and can exert negative effects on different biological processes. among the different methods of...

abstract the supracondylar process is a beak-like bony projection that arises from the anteromedial surface of the humerus. the process has rarely been associated with compression of the median nerve and seldom requires treatment. we report a case of a supracondylar process that caused tenting of the median nerve with elbow extension and pronation.

Mining, discovering, and integrating process-oriented services has attracted growing attention in the recent year. Workflow precedence graph and workflow block structures are two important factors for comparing and mining processes based on distance similarity measure. Some existing work has done on comparing workflow designs based on their precedence graphs. However, there lacks of standard di...

We consider P λ,τ policy of a dam inwhich thewater input is an increasing Lévy process. The release rate of the water is changed from 0 toM and fromM to 0 M > 0 at the moments when the water level upcrosses level λ and downcrosses level τ τ < λ , respectively. We determine the potential of the dam content and compute the total discounted as well as the long-run average cost. We also find the st...

CEP www.cepmagazine.org October 2005 25 The design of a chemical process involves synthesis and analysis. Process synthesis is the overall development of a process flowsheet by combining individual steps (equipment and operating conditions) into an optimal arrangement. Process analysis breaks down the flowsheet to evaluate the performance of each individual element as well as how the overall pr...

We introduce an ACP-style discrete-time process algebra with relative timing, that features the empty process. Extensions to this algebra are described, and ample attention is paid to the considerations and problems that arise when introducing the empty process. We prove time determinacy, soundness, completeness, and the axioms of standard concurrency. 1991 Mathematics Subject Classification: 6...
