Supported aqueous phase catalysis
… describes a novel family of catalysts denoted Supported Aqueous Phase Catalysts (S.A.P.C.). These catalysts consist of a water-soluble organometallic complex supported in a thin film of water residing on a high surface area hydrophilic solid; the reaction takes place at the water-organic …

Towards computer supported cooperative design
… after over a decade of developments in Computer Supported Cooperative Work, the state-of-the-art in collaborative technology does not fully support such activities. Two substantial case studies are presented. The first draws upon fieldwork with designers at a large, distributed engineering design …

Supported Programming for Beginning Developers
<p>Testing code is important, but writing test cases can be time consuming, particularly for beginning programmers who are already struggling to write an implementation. We present TestBuilder, a system for test case generation which uses an SMT solver to generate inputs to reach specified lines in …

Examining Community Integration of Individuals With Psychiatric Disabilities Residing In Supported and Non-Supported Housing
… integration experiences of individuals living in supported housing with the experiences of individuals living in non-supported housing (i.e., housing that is not attached to rehabilitative services). To achieve this goal, the NoCS study employed a mixed-methods design (qualitative and …

Enhanced structural characterisation of supported catalysts
… characterisation of the size and shape of carbon supported nanoparticle catalysts. Both monometallic (Pt or Au) and bimetallic (PtPd) catalysts were studied. In the first results chapter the strengths and weaknesses of various structural characterisation methods, TEM, XRD and EXAFS were explored. …

Scripts for Computer-Supported Collaborative Learning
Using computers as tools to mediate collaborative learning has had a profound impact on how we construct and communicate knowledge today. Computer interfaces have not been genuinely designed, however, to support collaborative knowledge construction. This study shows how computer interfaces can be …

Seismic Behavior of Pile -Supported Bridges
… interaction in seismic analysis of pile-supported bridges. The proposed model is applied to perform seismic performance evaluation of the Cairo Bridge for different excitation intensities and to identify an appropriate retrofit strategy for the bridge. Applications of the pile group model …

Coworker involvement in supported employment programs
… instrument to measure co-worker involvement in supported employment settings. Entitled the Co-worker Involvement Instrument, the scale assesses the presence of six co-worker roles (associating, training, befriending, evaluating, advocating, and information giving) and three variables influencing …

Structured assessment of pile supported piers
Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering; and, (S.M.)--Massachusetts Institute of Technology, Dept. of Ocean Engineering, 1999.

Mechanical Behavior of Posterior Implant Supported Restorations
… of different CAD/CAM customized implant-supported restorations using two materials, monolithic zirconia and monolithic lithium disilicate and using two crown designs, hybrid-abutment-crowns and hybrid-abutments with separate crowns. Thirty-two implants were embedded perpendicularly in an …

SOLID-SUPPORTED PORPHYRINS FOR CATALYSIS AND SENSING
… study was performed and the achieved data supported the occurrence of a radical mechanism mediated by putative nitrene radical cobalt intermediate1. Unfortunately, the grafting step of cobalt porphyrin onto CC sheets was unsuccessful therefore the synthesis of azobenzene under heterogeneous …

Systemic Evaluation Methodology for Technology Supported Learning
Developments in information and communication technologies have opened up new possibilities for organising and supporting learning activity. Appropriate evaluation methodology is required to help practitioners understand how and why their implemented learning designs work, so that they can improve …

Polymer-supported reagents for disinfection of water
A macroporous poly(styrene-co-divinylbenzene) resin having redox N,N-dichlorosulfonamide group, was modified for use in small-scale chlorination of potable water. The resin was synthesized via sulfonyl chloride by modification of the strong acid cation exchange resin, Amberlyst-15. The products …

A computational study of supported rhodium catalysts
… of heterogeneous catalysts based on rhodium supported on a metal oxide (-Al2O3). Two different methodologies were used. The first methodology uses a periodic model and a plane-wave basis set to solve the Schrödinger equation in the framework of Bloch’s theorem. The optimised structures of …
