Secondary Use of Laboratory data: Potentialities and Limitations

Standardizing clinical laboratory data for secondary use

Clinical databases provide a rich source of data for answering clinical research questions. However, the variables recorded in clinical data systems are often identified by local, idiosyncratic, and sometimes redundant and/or ambiguous names (or codes) rather than unique, well-organized codes from standard code systems. This reality discourages research use of such databases, because researcher...

Wet-STEM tomography: principles, potentialities and limitations.

The characterization of biological and inorganic materials by determining their three-dimensional structure in conditions closer to their native state is a major challenge of technological research. Environmental scanning electron microscopy (ESEM) provides access to the observation of hydrated samples in water environments. Here, we present a specific device for ESEM in the scanning transmissi...

Treatment of Textiles in Co2 – Potentialities and Limitations

While dyeing of poly(ethylene terephthalate) (PETP) fibres in supercritical carbon dioxide is now on its way to be transferred into the textile finishing industry to check the economic efficiency and practicability in an upscaled plant, dyeing of natural fibres such as cotton is still a problem. Within the paper an overview is given about the international stateof-the-art of dyeing technical (a...

Pulsed flows in flow analysis: Potentialities, limitations and applications.

In flow analysis, use of a steady and pulseless flow was considered essential for ensuring a reproducible handling of the flowing sample. To this end, peristaltic and syringe pumps have been the propelling device in the vast majority of the flow analysers. Recently, the number of applications involving pulsed flow has been increasing. Most of them refer to use of solenoid pumps, the essence of ...
