The New Watt Balance Experiment at Metas
The kilogram is the last unit of the international system (SI) still based on a material artifact, the international prototype of the kilogram (IPK). The comparisons made in the last hundred years have clearly revealed a long term relative drift between the IPK and a set of copies kept under similar conditions. Since the long term stability is one of the major conditions set on the SI base unit...
متن کاملParallel Key Encryption for CBC and Interleaved CBC
In current day scenario, the need to protect information has become very important and hence the need for cryptographic algorithms is high. Here, we extend the parallel key encryption algorithm and bring out its full potential by implementing the various cryptographic modes such as cipher block chaining and interleaved cipher block chaining where commendable increase in efficiency and reduction...
متن کاملMetas Do Design Pedagógico: Um Olhar Na Construção De Materiais Educacio- Nais Digitais
Due to the expansion of the internet and digital technologies in several areas of today's society, an increase in the application of digital resources in Education has been verified. However, most of these digital educational materials (DEM) are developed from the simple digitalization of analogic educational materials, usually occurring an unbalance among technical, graphic and pedagogic facto...
متن کاملThe new METAS Watt Balance, Mark II
In the context of the future new definition of the mass unit, kg, a promising route to link the mass unit to a fundamental constant, the Planck constant h, is represented by the watt balance experiment. Since a number of years, the Federal Institute of Metrology is active in this field and published a first result with its Mark I experiment in 2011. To reach the target uncertainty of 2 parts in...
متن کاملCap-binding complex (CBC)
The 7mG (7-methylguanosine cap) formed on mRNA is fundamental to eukaryotic gene expression. Protein complexes recruited to 7mG mediate key processing events throughout the lifetime of the transcript. One of the most important mediators of 7mG functions is CBC (cap-binding complex). CBC has a key role in several gene expression mechanisms, including transcription, splicing, transcript export an...
