This European Standard specifies a screening method for foods which contain DNA. It is based on micro-gel electrophoresis of single cells or nuclei to detect DNA fragmentation presumptive to irradiation treatment [1] to [8]. The DNA Comet Assay is not radiation specific, therefore, it is recommended to confirm positive results using a standardized method to specifically prove an irradiation tre...

This European Standard specifies a microbiological screening method for the detection of irradiation treatment of herbs and spices, using the combined direct epifluorescent filter technique (DEFT) and aerobic plate count (APC). The DEFT/APC technique is not radiation specific, therefore, it is recommended to confirm positive results using a standardised method (e.g. EN 1788, prEN 13751) to spec...

Tristel Sporicidal Wipes are chlorine dioxide-based disinfectant wipes for disinfecting non-lumened semi-critical medical devices. In this study, the mycobactericidal activity of this product was assessed by a modified version of the European Standard prEN 14563 carrier test under clean conditions against Mycobacterium avium. The chlorine dioxide concentration in the activated wipe was 200ppm. ...

The effect of annealing temperature (1000-1150 °C) on the microstructure evolution, mechanical properties, and pitting corrosion behavior of a newly developed novel lean duplex stainless steel with 20.53Cr-3.45Mn-2.08Ni-0.17N-0.31Mo was studied by means of optical metallographic microscopy (OMM), scanning electron microscopy (SEM), magnetic force microscopy (MFM), scanning Kelvin probe force mi...

Sugars are recognized as signaling molecules regulating the biosynthesis of secondary metabolites in plants. Here, a modulatory effect of sugars on dolichol and phytosterol profiles was noted in the hairy roots of Arabidopsis thaliana. Arabidopsis roots contain a complex dolichol mixture comprising three groups ('families') of dolichols differing in the chain-length. These dolichols, especially...

The formation mode of isolated austenite (IA) formed during high-temperature cooling and its effect on pitting corrosion resistance S32750 DSS were investigated. As the structure process after hot rolling in duplex stainless steel (DSS), precipitation can be considered as combined production temperature rates. IA generated at ferrite (α) grain boundaries or internal α performed K-S crystallogra...

This work describes an implementation of a proof-of-concept layer to export medical data from a health information system in a CEN prEN 13606 compliant format. The resulting EHR extracts are deposited in a local repository. The export-layer is based on Oracle PL/SQL and the PL/SQL DOM API. EHR extracts are described by means of two XML Schemas and are transformed into Archetype compliant EHR ex...

The antimicrobial efficacies of preparations for surgical hand antisepsis can be determined according to a European standard (prEN 12791 [EN]) and a U.S. standard (tentative final monograph for health care antiseptic drug products [TFM]). The U.S. method differs in the product application mode (hands and lower forearms, versus hands only in EN), the number of applications (11 over 5 days, versu...

This article highlights the most relevant aspects of new generation Eurocodes for assessment existing structures, and in particular those governing concrete structures. In this respect, Eurocode 0 will include a section (prEN 1990-2. Basis retrofitting structures: general rules actions) covering approach analysis that must be included type assessment, while 2 (prEN1992-1-1:2021 Design structure...
