European Union law enforces labeling of products containing above 0.9% of GMO. The aim of this study was detection and quantification of genetically modified rape in feedingstuffs. Both the qualitative and quantitative analysis was based on Real Time PCR method. Amongst 432 examined samples of feed, 56 contained GM rape line GT73. Only in 8 of them did the content of GM rape exceed 0.9%. The source of GT73 rape contamination was rapeseed meal imported to Poland from the eastern countries, mainly Ukraine, which was confirmed in shipping documents attached to the samples. The efficient monitoring of GMO, especially for rape, is very important, because of the high possibility of contamination of traditional crops with GM varieties

Based on the European regulation, the Czech Association of Breweries and Malthouses recommends 2.5 mg/kg as maximum permitted concentration of melamine for beer, barley, malt, hop, and their products. For this reason, the first analytical method for melamine determination in beer and beer-type beverages was developed. The sample preparation included ion-exchange solid-phase extraction and subsequent derivatization with BSTFA. Qualitative and quantitative analysis was performed by gas chromatography with tandem mass spectrometry. Validation parameters of the method, such as limits of detection and quantification were 0.1 mg/L and 0.4 mg/L, respectively. Extended uncertainty of the final method was evaluated to 0.1 mg/L. The method was applied on twenty samples of beer lagers, or other beer styles; all had the level of melamine under the limit of quantification (< 0.4 mg/L).

In this paper I analyze Swahili conditional constructions via corpus analysis. Previous works on Swahili conditional markers categorize ki as a high possibility marker and ikiwa as a low possibility marker. In this corpus based study, I show that Swahili conditional markers cannot be imbued with specific pragmatic implicatures. Further, I extend the analysis to include the relationship between the protasis and apodosis and how this relationship impacts the choice of Swahili conditional markers. Qualitative and quantitative analysis of the results indicate that both ki and ikiwa may be used in conditionals with a high as well as neutral possibility of realization. However, the conditional conjunction ikiwa significantly differs from the ki conditional morpheme in the analysis based on the relationship between the protasis and apodosis. While ki is more frequently used in content and speech act conditionals, ikiwa is more frequently used in epistemic conditionals. The study is also extended to include the Swahili subjunctive morphemes nge, used in conditionals with a low possibility of realization (hypotheticals) as well as counterfactuals, and ngeli/ngali, predominantly used in counterfactuals.
