This study focuses on optimization and validation of an Ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method for simultaneous analysis of 11mycotoxins: Aflatoxin B1, T-2 Toxin, Ochratoxin A, Deoxynivalenol and Zearalenone in wheat matrix. Sample extraction and cleanup procedure is based on a single extraction step using acetonitrile/water/acetic acid mixture...

In archived samples from the German environmental specimen bank (ESB) organotin compounds including tributyltin (TBT) and triphenyltin (TPT) as well as their potential degradation products were quantified. Muscles of bream (Abramis brama) sampled in the period 1993-2003 from the rivers Rhine, Elbe, Saale, Mulde, Saar, and from Lake Belau (period 1988-2003) were analyzed by gas chromatography/at...

Historically, economic changes have negatively affected the nursing workforce in Ontario. The trend towards part-time and casual employment emerged from healthcare restructuring in the 1990s. The severe acute respiratory syndrome (SARS) outbreak in 2003 alerted the Ontario government to the issue of part-time and casual nursing. In 2007, the Nursing Graduate Guarantee (NGG), a health human reso...

Wide distribution of chlorinated paraffins in the environment has already been demonstrated in several studies; however, information about their levels in the Central Europe is still very limited. First study focused on the SCCP contamination of the Czech aquatic environment have been performed recently, and its results motivated the authors to analyze sediments from a wide set of the Czech riv...

The GridTrust Security Framework (GSF) offers security and trust management for the next generation Grids (NGG). It follows a vertical approach for Grid security from requirements level right down to application and middleware levels. New access control models for collaborative computing, such as the usage control model (UCON), are implemented for securing the Grid systems. The GSF is composed ...

Data and information in the development of digital technology have an important role. Every activity or that uses is related to data information, so security confidentiality are very important. To maintain confidentiality, protection with cryptographic techniques needed. Cryptographic encryption, which where process scrambling carried out hiding a key system, while decryption changing condition...

In this article we present some weaknesses in the RC4 cipher and their cryptographic applications. Especially we improve the attack described in [2] in such a way, that it will work, if the weak keys described in that paper are avoided. A further attack will work even if the first 256 Byte of the output remain unused. Finally we show that variants of the RC4 algorithm like NGG and RC4A are also...
