Study of the hadronic current in the neutrino interactions of the OPERA experiment
(Universita degli studi di Salerno, 2013-04-22)The OPERA experiment was designed to observe the appearance of the vr in a pure beam ofvll (CNGS). The evidence ofthe appearance signal is provided by the detection of the daughter particles produced in the decay of ... -
In silico study of protein-protein interactions
(Universita degli studi di Salerno, 2013-01-30)Protein-protein interactions are at the basis of many of the most important molecular processes in the cell, which explains the constantly growing interest within the scientific community for the structural characterization ... -
Memetic algorithms for ontology alignment
(Universita degli studi di Salerno, 2013-04-24)Semantic interoperability represents the capability of two or more systems to meaningfully and accurately interpret the exchanged data so as to produce useful results. It is an essential feature of all distributed and ... -
Design, synthesis and biological evaluation of new non-nucleosidic inhibitors od DNA methyltransferases
(Universita degli studi di Salerno, 2013-04-03)The inactivation of tumor suppressor genes, which often results from epigenetic silencing associated with DNA hypermethylation, plays a pivotal role in the development of most forms of human cancer. Moreover, there are ... -
Some group properties associated with two-variable words
(Universita degli studi di Salerno, 2013-04-03)Let w(x; y) be a word in two variables and W the variety determined by w. In this thesis, which includes a work made in collaboration with C. Nicotera [5], we raise the following question: if for every pair of elements ... -
