A survey of trichothecenes, zearalenone and patulin in milled grain-based products using GC-MS/MS.
2013
An analytical protocol based on QuEChERS and gas chromatography-tandem mass spectrometry (GC-MS/MS) was successfully applied for the determination of trichothecenes, patulin and zearalenone in 182 milled grain-based samples. The analytical method was validated following the SANCO 1495/2011 document. LOQs were lower than 10μgkg(-1) for the selected mycotoxins. Recoveries of fortified cereals ranged between 76-108% and 77-114% at 20 and 80μgkg(-1), respectively, with relative standard deviation lower than 9%. More than 60% of the samples analysed showed deoxynivalenol contamination, followed by HT-2 toxin and nivalenol with frequencies of 12.1% and 10.4%, respectively. Co-occurrence of mycoto…
Occurrence and co-occurrence of Fusarium mycotoxins in wheat grains and wheat flour from Romania
2017
Abstract In this study, the presence of fourteen Fusarium mycotoxins, legislated by the European Union – deoxynivalenol, zearalenone, HT-2 and T-2 toxins (EC/1881/2006; 2013/165/EU), or non-legislated (five trichothecens and five “emerging” mycotoxins), was evaluated in 31 whole unprocessed wheat samples and 35 white wheat flour samples from different areas of Romania. For this purpose, a validated multi-mycotoxins liquid chromatography tandem mass spectrometry method was applied. Seventy three percent of the analyzed samples contained at least one mycotoxin. The highest occurrence was for enniatin B, 71% of the analyzed samples being positive (21–407 μg kg−1). Regarding the legislated myco…
The birth and youth of Compositio Mathematica: ‘Ce périodique foncièrement international’
2006
The journal Compositio Mathematica was founded by Luitzen E. J. Brouwer to counter his dismissal from the Mathematische Annalen in 1928. In spite of the economic crisis, Brouwer succeeded in finding a publisher (Noordhoff), an editorial board and subscribers. The founding took place at the time of the rise of the Third Reich, which caused problems of a political nature. The German editors followed Ludwig Bieberbach in 1934 when he left the board because Brouwer refused to dismiss the Jewish editors. After a period of flourishing, the publication was suspended at the beginning of the occupation of Holland in 1940. The post-war restart of the journal led to a painful conflict between Brouwer …
Influence of prebiotics, probiotics and protein ingredients on mycotoxin bioaccessibility
2015
The aim of this study was to investigate the influence of prebiotic compounds (cellulose and inulin), food ingredients (milk whey, β-lactoglobulin and calcium caseinate) and several probiotic microorganisms on the bioaccessibility of beauvericin (BEA), enniatins (ENs A, A1, B, B1), deoxynivalenol (DON) and zearalenone (ZEA) present in wheat crispy bread produced with wheat flour previously fermented with F. tricinctum, F. culmorum and G. zeae. The bioaccessibility of mycotoxins was determined by a dynamic simulated gastrointestinal digestion system, imitating the human digestive physiological conditions of the gastrointestinal tract. Mycotoxins were determined in the simulated intestinal fl…

Who Moves to Depressed Regions? An Analysis of Migration Streams in Finland in the 1990s
2002
Depressed regions typically lose a large number of migrants but simultaneously are destination regions for some migrants. This study analyzes those people who decided to move to depressed regions in Finland in 1993-1996. The analysis is based on a 1 percent sample drawn from the Finnish longitudinal census. The results show that migration into depressed regions is also a selective process. Return migration is only one part of this migration. However, the more educated an individual is, the more likely she or he is to move to a flourishing region. The process of concentration of human capital is reinforced by interregional migration.
Rheological Evaluation of Some Commercial Xylanases
2011
The arabinoxylans play and the xylanases play an important role breadmaking. For a better selection of xylanases, it is necessary to understand how they work in breadmaking. At the same activity, the xylanases have different effect on dough rheology. The xylanases activity measured through birch xylan hydrolysis it is not correlated with extensographic effects. Weak but better correlations were observed when the xylanase activity was measured as the ability to decrease the viscosity of soluble wheat arabinoxylans solution.
Industrial application of selected lactic acid bacteria isolated from local semolinas for typical sourdough bread production
2016
Abstract Four obligate heterofermentative lactic acid bacteria (LAB) strains (Weissella cibaria PON10030 and PON10032 and Leuconostoc citreum PON 10079 and PON10080) were tested as single strain starters, mono-species dual strain starters, and multiple strain starter for the preparation and propagation of sourdoughs for the production of a typical bread at industrial level. The kinetics of pH and TTA during the daily sourdough refreshments indicated a correct acidification process for all trials. The concentration of lactic and acetic acid increased consistently during fermentation. The resulting molar ratios between these two organic acids in the experimental trials were lower than those o…
Human Resources Management Practices Perception and Extra-Role Behaviors: The Role of Employability and Learning at Work
2021
Human Resource Management (HRM) processes are considered the beating heart of any successful organization. Recently, several studies have highlighted how organizations can use commitment-oriented HR practices to generate organizational and individual effectiveness. The aim of this study was to verify whether the perception of HRM practices could be able to elicit extra-role behaviors and, at the same time, whether this relationship could be mediated by employability and learning conditions. The analyses were carried out on a sample of 1219 Italian workers using Structural Equation Models. The structural model yielded good fit indices and the results showed a significant and positive effect …
