With 27 years experience as an external quality assurance control, the proficiency program coordinated by the Madrid Department of the INTCF and organized by the Spanish and Portuguese Speaking Working Group of the ISFG (GHEP-ISFG) offers its Basic l

In this paper a setup for detecting malfunctioning areas of MEAs in fuel cell stacks is described. Malfunctioning areas generate electric cross currents inside bipolar plates. To exploit this we suggest bipolar plates consisting not of two but of thr

Accurate external measurements are required in tomographic problems to obtain a reasonable knowledge of the internal structures. Crucial is the distribution of the external measuring points. We suggest a procedure how to systematically optimize this

A novel scheme for detecting inhomogeneous internal currents in a fuel cell stack is presented. In this paper the scheme is investigated for the case that the flow field plates consist of graphite. Then plates of high conductivity, e.g. aluminium bet

A novel tomographic scheme for analysing the state of any single membrane electrode assembly (MEA) in a stack is suggested. Plates of very high conductivity placed between every fuel cell and slitted in an appropriate manner cause surface currents at

We explore different designs to estimate both nuclear and mitochondrial human DNA (mtDNA) content based on the detection of the 5′ nuclease activity of the Taq DNA polymerase using fluorogenic probes and a real-time quantitative PCR detection syste

We present a study of 109 unrelated males from an Andalusian population (southern Spain) for minimal haplotype using in parallel the Y-Plex™ 6 STR kit (Reliagene Technologies) and amplification and typing protocols according to Elmoznino and Prinz

Here we present allele frequencies for 15 STRs determined in samples from unrelated individuals from Extremadura using the Profiler Plus™, COfiler™, SGM Plus™ and PowerPlex™ 16 multiplex systems. Detection was made by capillary electrophoresi

Electrolytes with high ionic diffusivity at temperatures distinctively lower than the presently used ones are the prerequisite for the success of, e.g., solid oxide fuel cells. We have found a promising structure having an asymmetric but superior ion

This year the annual GEP-ISFG proficiency test consisted of two practical and three theoretical exercises. The practical exercise included a deficiency maternity test for which blood samples from a woman and two alleged children were analyzed and a f
