Multiple Pulse Amperometry-An Antifouling Approach for Nitrite Determination Using Carbon Fiber Microelectrodes.

Nitrite is a ubiquitous pollutant in modern society. Developing new strategies for its determination is very important, and electroanalytical methods present outstanding performance on this task. However, the use of bare electrodes is not recommended because of their predisposition to poisoning and passivation.

A pairwise alignment algorithm which favors clusters of blocks.

Pairwise sequence alignments aim to decide whether two sequences are related and, if so, to exhibit their related domains. Recent works have pointed out that a significant number of true homologous sequences are missed when using classical comparison algorithms. This is the case when two homologous sequences share several little blocks of homology, too small to lead to a significant score.

How to convince your manager to invest in an HIS preimplementation methodology for appraisal of material, process and human costs and benefits.

Investing in information technology has become a crucial process in hospital management today. Medical and administrative managers are faced with difficulties in measuring medical information technology costs and benefits due to the complexity of the domain. This paper proposes a preimplementation methodology for evaluating and appraising material, process and human costs and benefits.

Activity modelling for assessing the usability of telematics applications in healthcare.

With the development of Telematics Applications in Healthcare, it becomes obvious that the success of these services is tightly linked with their usability and their acceptance by users. That is why Users Requirements Analysis appears as an essential step before implementation of new computer services. In many cases, particularly when doctors are directly involved in the management of information, there is a strong interaction between their usual activity and the new tasks implied by the computer.

[Amalgamated and reinforced bone powder graft in the correction of the nasal ridge].

A number of surgical procedures have been described to correct irregularities of the consequences of excessive resection of the nasal ridge. Among these procedures the authors propose a bone powder graft mixed with tissue glue and reinforced with surgicel. The graft is in the form of a sheet of variable thickness which is malleable and can be perfectly shaped to fit the nasal ridge.
