CAN J ANESTH 55: 8 www.cja-jca.org August, 2008 ment with a bolus, followed by continuous infusion of naloxone, and tracheal intubation was not needed. Subsequent testing of the PCA determined that, when the door of the PCA was closed, due to a defect in the pump, there was unintended pressure on the free flow protection device which allowed for free flow. This defect was not visible to the nak...

Sintering of nanosilver paste has been extensively studied as a lead-free die-attach solution for bonding semiconductor power chips, such as the power insulated gated bipolar transistor (IGBT). However, for the traditional method of bonding IGBT chips, an external pressure of a few MPa is reported necessary for the sintering time of ~1 h. In order to shorten the processing duration time, we dev...

A high-speed processor for the recognition and location of object features is presented. The svstem is equipped with a powerful coprocessor to compute the normalized cross-correlation. An application in industry demonstrates the systems benefits. Flexible systems for industrial automation dema~d sophisticated techniques for visual observation of the scene. Completeness checks, alignment and gau...

Nitrophorins represent a unique class of heme proteins that are able to perform the delicate transportation and release of the free-radical gaseous messenger nitric oxide (NO) in a pH-triggered manner. Besides its ability to bind to phospholipid membranes, the N-terminus contains an additional Leu-Pro-Gly stretch, which is a unique sequence trait, and the heme cavity is significantly altered wi...

Two methods of attaching fluidic interconnects are presented. By using gold to gold fusion bonding and copper to gold fusion bonding, micro-scale tubes are attached to a MUMPS fabricated fluidic channel. The fusion bonding is done by resistively heating a gold layer on top of the poly 2 layer, so that the gold melts. A range of different heater geometries is presented. The tensile and shear str...

There has recently been considerable interest in the use of lexically-based statistical techniques to resolve prepositional phrase attachments. To our knowledge, however, these investigations have only considered the problem of attaching the first PP, i.e., in a [V NP PP] configuration. In this paper, we consider one technique which has been successfully applied to this problem, backed-off esti...

Given any connected, open 3-manifold U having finitely many ends, a non-compact 3-manifold M is constructed having the following properties: the interior of M is homeomorphic to U ; the boundary of M is the disjoint union of finitely many planes; M is not almost compact; M is eventually end-irreducible; there are no proper, incompressible embeddings of S ×R in M ; every compact subset of M is c...

Enteropathogenic Escherichia coli and enterohemorrhagic E. coli are diarrheagenic bacterial human pathogens that cause severe gastroenteritis. These enteric pathotypes, together with the mouse pathogen Citrobacter rodentium, belong to the family of attaching and effacing pathogens that form a distinctive histological lesion in the intestinal epithelium. The virulence of these bacteria depends o...

Attaching monothiolated DNA to silver nanoparticles has been achieved at pH 3.0 in 30 minutes and difficulties associated with DNA attachment to AgNPs at neutral pH have been revealed by studying DNA adsorption kinetics.

Attaching dialkylaminomethyl arms to commercial phenolic oxime copper extractants yields reagents which transport base metal salts very efficiently by forming neutral 1:1 or 1:2 complexes with zwitterionic forms of the ligands.
