OBJECTIVES In order to measure occupational exposure concentrations of ethyl tertiary-butyl ether (ETBE), we developed a diffusive sampling method for monitoring ETBE and performed an ETBE exposure assessment. METHODS The applicability of diffusive samplers was examined by exposing the samplers to ETBE vapor in test chambers. The personal exposure levels of workers and airborne concentrations...

This article presents the accounts of China’s Total Material Requirement (TMR) during 1995–2008, which were compiled under the guidelines of Eurostat (2009) and with the Hidden Flow (HF) coefficients developed by the Wuppertal Institute. Subsequently, comparisons with previous studies are conducted. Using decomposition, we finally examine the influential factors that have changed the TMR of Chi...

The phrase virtual source refers to two different techniques in this dissertation. In the first half of the dissertation, it refers to interferometry and in the second half it uses the concept of the synthetic aperture technique. In interferometry, a receiver is converted to a “virtual source”. In the synthetic aperture technique, a large “virtual source” is constructed by adding small sources....

Proteins within the living cell potentially possess different spatial localizations and a wide range of diffusivities . At one extreme, proteins may be essentially nondiffusive-that is, highly localized structural components of the cytoplasm and/ or nucleus, with very long or infinite residence-times. An extensive, proteinaceous cytomatrix network consisting ofthe polymerized proteins of microt...

We review recent developments in the theory of supermembranes and their relation to matrix models. Lecture presented at the Corfu Workshop, September 20 26, 1998, of the TMR Project Quantum Aspects of Gauge Theories, Supersymmetry and Unification (ERBFMRXCT960045), to appear in the proceedings.

This paper presents our industrial experience on the implementation of SpeedyDes3 encryption which is a speed up version of the Des3 encryption. This SpeedyDes3 encryption improves the standard Des3 encryption by means of speed and memory usage. Our SpeedyDes3 encryption is particular suitable for use/running in small systems. We have applied the SpeedyDes3 for the encryption of data in video p...
