The science and management of environmental- and water-related issues requires an interdisciplinary approach, as recognized by funding agencies, consulting firms, and public organizations. In their role of preparing students for productive professional careers, academic institutions should be able to train students in interdisciplinary approaches, but complications exist in current academic environments that make interdisciplinary education especially challenging. We provide a vision of interdisciplinary graduate education in water and environmental resources in 2050 after presenting a brief assessment of current issues in interdisciplinary education. © 2010 ASCE.

As part of an extensive University - K-12 partnership program in STEM (science, technology, engineering and math) disciplines, more than 20 faculty members at Clarkson University have developed and taught summer institutes and workshops for area middle and high school teachers. The goals of these interventions are to provide rigorous and state-of-the-art STEM content knowledge, to model effective and active teaching strategies, and to prepare the teachers to bring the new STEM content into their classrooms. The 5-day summer institutes provide rigorous content and hands-on activities for the teachers. The objective of this paper is to describe the development and assessment of the institutes. The design of the institutes was based on educational research that has documented key features of professional development and careful evaluation of prior professional development activities in the region. The optimal partnership was defined as one where teachers partner with working scientists, mathematicians, and engineers who have sophisticated equipment in laboratory work space, computing facilities and other resources of higher education. During the past two years, approximately 250 individuals attended 22 institutes;some of the teachers attended multiple offerings. The efficacy and impact of these institutes has been assessed through pre- and post content knowledge or capability tests, evaluation forms, and peer-review of lessons developed as an outcome of the institutes. For all institutes, evaluations indicated a statistically significant increase in STEM content knowledge and evaluations were remarkable. The transfer of this knowledge by the teachers into classroom lesson plans and activities, and the peer review of that outcome are on-going. © American Society for engineering Education, 2010.

This research aimed to investigate the potential of partial substitution of cement raw meal with grinding sludge as an alternative raw material in Portland cement clinker production. Cement raw mixtures with up to 3% raw mix replacement were put through a burning process in a high-temperature furnace. One reference and three modified mixtures, containing 1, 2 and 3% dry weight of grinding sludge were examined. XRF analysis results showed that CaO, SiO2, A12O3 and Fe2O3 in ordinary cement raw meal were within typical concentration ranges. The grinding sludge had high concentrations of iron, cadmium, chromium and nickel and was consequently classified as a hazardous waste. High Fe2O3 made the grinding sludge a good candidate for alternative raw material. Higher replacement of grinding sludge was found to improve burnability, reduce formation of major of cement compositions (dicalcium silicate, C2S and tricalcium aluminate, C3A), lower in silica and alumina ratios, but promote the formation of tricalcium silicate (C3S) and tetracalcium aluminateferrite (C4AF). Microstructural analysis of the synthesized Portland clinker revealed that the grinding sludge promoted formation of secondary C2S as well as caused color change of C3S. Thai regulatory leaching procedure was performed on the synthesized clinker and mortar samples. The concentrations of heavy metals in the leachate were found below the limits. Moreover, the maximum substitution of grinding sludge was found to be 2% of grinding sludge. Thus, this sludge has potential applications as an alternative raw material in cement production. © 2010 Asian Network for Scientific Information.

A hierarchical set of kinetic models were proposed and discussed for simulation of autocatalytic decomposition of cumene hydroperoxide (CHP) in cumene at low temperatures. The hierarchy leads from a formal model of full autocatalysis, which is based on conversion degree as a state variable, through a two-stage autocatalytic concentration-based model to a meticulous multi-stage model of the reaction. By the ForK (Formal Kinetics) and DesK (Descriptive Kinetics) software, developed by ChemInform Saint Petersburg (CISP) Ltd., the related kinetic parameters and their significance have also been estimated and elucidated. Through this best-fit approach, it is possible to formulate a systematic methodology on the kinetic studies for thermal decomposition of typical organic peroxides with autocatalytic nature, specifically at low temperature ranges. © 2009 Akadémiai Kiadó, Budapest, Hungary.

A lattice Boltzmann method (LBM) on high performance computing (HPC) environments for three-dimensional shallow water flow fields is developed. Recently, the LBM has become an attractive numerical method to solve various fluid dynamics phenomena. However, LBM has not been extensively applied to shallow water equations. The shallow water equations have wide applications in ocean and hydraulic engineering which can benefit from the advantages of the LBM. The standard LBM for two dimensional shallow water flows is extended to three dimensional flows by solving the multilayer shallow water equations. LBM is an attractive method for solving the multilayered shallow water equations because the extension to a multilayer formulation is straight forward and all simplicities and advantages of the LBM are retained. The performance of the LBM for the multilayer shallow water equations is investigated and optimized in HPC environments. We numerically demonstrate the applicability of the LBM in three dimensional shallow water flows and the LBM performance using OpenMP. © 2009 ASCE.

Styrene is an important chemical in the petrochemical industry. In recent years, there have been sporadic releases, runaway reactions, fires, and thermal explosion accidents incurred by styrene and its derivatives worldwide. The purpose of this study was to estimate the impact of styrene and its derivatives of α-methylstyrene (AMS) and trans-β-methylstyrene (TBMS) contacting with benzaldehyde. Experiments were carried out to evaluate the thermokinetic parameters estimated by differential scanning calorimetry (DSC) and thermal activity monitor III (TAM III). TAM III was used to determine the fundamental thermokinetics under various isothermal temperatures, 80, 90 and 100C. This autocatalytic reaction was demonstrated in thermal curves. After styrene was contacted with benzaldehyde, the exothermic onset temperature (T 0) and the total heat of reaction (Q total) were altered by DSC tests. When benzaldehyde is mixed with AMS and TBMS, the reaction time will be shorter but the enthalpy reduced, as revealed by TAM III tests. As AMS and TBMS, respectively, were contacted with benzaldehyde, both exothermic phenomena were changed during the reaction excursion. According to the results of this research, an operator should dictate the oxygen concentration in order to avoid any potential hazards during handling and transportation. © 2009 Akadémiai Kiadó, Budapest.

In petrochemistry, dicumyl peroxide (DCPO) is used in various resins for improving physical properties, which was produced by cumene hydroperoxide (CHP) with oxidization reaction, redox reaction, and dehydration reaction. The reactant, CHP, is a typical organic hydroperoxide and has been intrinsically unstable and reactive due to its bivalent -O-O- structure which can be broken readily with bond-dissociation energy. This sequence on sensitive study aimed at the thermal hazard evaluation for the reactive and incompatible characteristics of CHP mixed with various inorganic alkaline solutions. Differential scanning calorimetry (DSC) and vent sizing package 2 (VSP2) were used to analyze the thermal hazards and runaway reaction of redox system, such as decomposition of CHP in cumene solution and CHP react with inorganic alkaline solutions, exothermic onset temperature, peak power, heat of decomposition of dynamic scanning tests, adiabatic self-heating rate, pressure rise rate, maximum temperature, maximum pressure of reaction system, etc. The results of the tests have proven helpful in establishing safe handling, storage, transportation, and disposal guidelines. © 2009 Akadémiai Kiadó, Budapest.

To take an advantageous stance in the recent competition of semiconductor industries, companies have made efforts to invest terms of technological advancements. From 1993 to 2006, enormous fire accidents occurred in three national science parks in Taiwan. This research focused on whether the very early smoke detection apparatus (VESDA), could adequately assist the emergency response center (ERC) members to take actions when alarm occurs. Besides, the research also analyzed every VESDA alarm that happened from 2004 to 2006 for the purpose of increasing ERC personnel's experience and coordinating ERC with departments of safety management, environmental protection, facility engineering, and equipment sections together to investigate better solutions to related problems.
