Some topics in the theory of generalized fc-groups
(Universita degli studi di Salerno, 2011-02-15)A finiteness condition is a group-theoretical property which is possessed by all finite groups: thus it is a generalization of finiteness. This embraces an immensely wide collection of properties like, for example, ... -
Steganographic methods for information hiding in MS-Office files
(Universita degli studi di Salerno, 2013-04-20)The simplest container of digital information is “the file" and among the vast array of files currently available, MS-Office files are probably the most widely used. These files, starting from MS-Office 2007, respect the ... -

(Universita degli studi di Salerno, 2013-01-30)This PhD work describes the development of different Michael and Michael type processes employing different bifunctional organocatalysts. All the processes studied involved a non-covalent activation of the substrates ... -
Stereoselectivity in asymmetric processes and molecular assemblies
(Universita degli studi di Salerno, 2020-02-19)The aim of this thesis was to explore different areas of organic chemistry in which the stereocontrol in the design of chemical processes and/or molecular assemblies is necessary. Therefore, the stereoselectivity in ... -
Stochastic diffusion processes with jumps for cancer growth and neuronal activity models
(Universita degli studi di Salerno, 2015-05-22)In the last decades, great attention has been paid to the description of bio- logical, physical and engineering systems subject to various types of jumps. A jump, or catastrophe, is considered as a random event that ... -
Stochastic processes governed by the generalized telegraph process and by Brownian motion and their applications
(Universita degli studi di Salerno, 2021-06-18)The aim of this research thesis is to broaden the treatment of stochastic processes derived from the telegraph process and Brownian motion. First, the classical telegraph process is presented. The Kolmogorov equations ... -
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 ... -
Superconductivity in S/F hybrids: a Scanning Probe Microscopy study of orbital interaction
(Universita degli studi di Salerno, 2016-04-14)In the framework of the Ginzburg-Landau (G-L) theory [1], conventional superconductors are classified in type I and type II, based on the value the G-L parameter... [edited by author] -
Supercritical assisted processes for the production of biopolymeric micro and nanocarriers
(Universita degli studi di Salerno, 2015-04-20)This work provides an innovative point of view on obtaining nanoparticles by supercritical fluids. Supercritical fluids have already been exploited in the production and processing of micro or sub-micro particles, but the ... -
Supported gold nanoparticles as promising catalysts in sustainable organic synthesis
(Universita degli studi di Salerno, 2021-03-23)Gold nanoparticles (AuNPs) emerged as very promising catalysts in a lot of organic reactions and industrial applications. These catalysts are in fact capable of catalysing chemical processes under mild conditions ... -
Supporting learning activities in virtual worlds: methods, tools and evaluation
(Universita degli studi di Salerno, 2013-02-27)Continuing advances and reduced costs in computational power, graphics and network bandwidth let 3D immersive multi‐user Virtual Worlds (VWs) become increasingly accessible while offering an improved and engaging quality ... -
Supramolecular Scaffolds for Biomimetic Catalysis
(Universita degli studi di Salerno, 2018-03-02)This PhD thesis is concerned with the design, synthesis and the characterization of supramolecular scaffolds for biomimetic catalysis. Development of new organocatalytic systems based upon well-designed calix[4]arene ... -
Sustainable catalysis by polymer supported gold nanoparticles
(Universita degli studi di Salerno, 2016-03-16)Gold Nanoparticles are nanomaterials whose properties are completely different from the ones of the bulk material. Nowadays many chemists have been using them as catalysts which work under mild conditions and respect the ... -
