Biological effects of radiofrequency fields: Testing a paradigm shift in dosimetry

Specific absorption rate Abstract: Biological effects have been reproducibly reported in rodents exposed to radiofrequency fields (RF) without significant change of the body temperature. These observations ...

Investigation of migrating substances from textile used as food contact material

this issue, migration experiments were carried out using food simulants. Consequently, the bread bag was brought into contact with the simulants for bread using accelerated time and temperature ...

Development of a sample preparation method for the GC-analysis of e-cigarette refill liquids

limit the transfer of the matrix to the column. The headspace temperature was chosen in  order to obtain an optimal transfer of the target components to the headspace with minimal transfer of the matrix ...

The Use of Tenax® as a Simulant for the Migration of Contaminants in Dry Foodstuffs: A Review

come into contact with food specifies the use of the adsorbent poly(2,6‐diphenylphenylene oxide) or Tenax® as a simulant for dry foodstuffs. Already in 2010, Tenax® migration profiles in the temperature ...

A simple dilute-and-shoot method for screening and simultaneous quantification of nicotine and alkaloid impurities in electronic cigarette refills (e-liquids) by UHPLC-DAD

excluded. In addition, small changes to the column temperature, pH and molar concentration of the mobile phase buffer were deliberately introduced in order to assess the robustness of the method. Only ...

European all-cause excess and influenza-attributable mortality in the 2017/18 season: should the burden of influenza B be reconsidered?

using the FluMOMO algorithm, incorporating influenza activity based on clinical and virological surveillance data, and adjusting for extreme temperatures. Results Excess mortality was mainly attributable ...

Occurrence and identification of spore-forming bacteria in skim-milk powders

representative of the various tests. Of the isolates identified, 68% were  Bacillus licheniformis, a facultative anaerobe that can survive and grow at mesophilic and thermophilic temperatures, making it difficult ...
