Biosensors are analytical devices being approachable for multiple analytes assay. Here, biosensors with intercepted acetylcholinesterase (AChE) or butyrylcholinesterase (BChE) are presented as tool for assay of anticholinergic compounds such as pesticides, nerve agents and some natural toxins. Principle of assay is based on evaluation of cholinesterase activity and its pertinent decrease in pre...

We investigate the number of speakers and the amount of data that is required for the development of useable speakerindependent speech-recognition systems in resource-scarce languages. Our experiments employ the Lwazi corpus, which contains speech in the eleven official languages of South Africa. We find that a surprisingly small number of speakers (fewer than 50) and around 10 to 20 hours of s...

This paper explores the use of perturbation in designing multiperformer or multi-agent interactive musical interfaces. A problem with the multi-performer approach is how to cohesively organize the independent data inputs into useable control information for synthesis engines. Perturbation has proven useful for navigating multi-agent NIMEs. The author’s Windtree is discussed as an example multi-...

Heat-assisted magnetic recording (HAMR) is expected to be a realistic next-generation technology for increasing the density of hard disks. However, layer heated above Curie temperature, and, as result, lubricant desorbed from disk by decomposition and evaporation, which causes problem it adheres air-bearing surface (ABS) smear. In this study, pyrolysis gas chromatography/mass spectrometry (Py-G...

The field of peer-to-peer reputation systems has exploded in the last few years. Our goal is to organize existing ideas and work to facilitate system design. We present a taxonomy of reputation system components, their properties, and discuss how user behavior and technical constraints can conflict. In our discussion, we describe research that exemplifies compromises made to deliver a useable, ...

A simple method for the preparation of cis-dichloro(1,4,7-triazacyclononane)platinum(II), cis-Pt(tacn)Cl(2) is presented, together with the results of screening the compound against the K-562 (leukemia) and SK-OV-3 (ovarian) human cancer cell lines. While the compound shows no activity against K-562 cells, there is evidence for some cytotoxicity against SK-OV-3. The compound is much less effect...

This study's objective was to assess the usability of the epilepsy history module of the electronic patient record, developed at Beaumont Hospital, and to identify opportunities for improvement. Observation, interview and document analysis methods were used. Results indicated that the module was useable but the design did not work as well in practice as anticipated by theory. The next iteration...

dialysis-cryoprotected crystals were flash-cooled [1], using a nitrogen stream at about 105K. Using our in-house X-ray equipment for the vault crystals, we can observe diffraction strength, but we cannot collect diffraction data. In-house, the best of the C2 form crystals resulted in articulated but unresolved diffraction lunes. Only a few percent of the tested vault crystals have produced usea...

We consider a highly unconventional approach to generating muon and antimuon bunches for a neutrino factory or muon collider: electronpositron annihilation just above muon-antimuon threshold. This approach can produce low-emittance bunches at high energy, easing the muoncooling and acceleration challenges in such facilities. However, the small (< 1μb) useable production cross section means that...

Heating tomato fruit (Lycoperiscon esculentum) for 48 h at 38 degrees C prevented chilling injury from developing after 21 d at 2 degrees C, whereas unheated fruit developed high levels of injury. Although the overall protein pattern as seen by Coomassie blue staining was similar from heated and unheated fruit, some high- and many low-molecular-mass proteins were observed in the heated fruit th...
