No full textTUTELA DEL LAVORO E LIBERTA' D'IMPRESA NEI PROCESSI DI ESTERNALIZZAZIONE
No full textL’elaborato analizza le conseguenze lavoristiche della successione fra imprenditori, muovendo da una ricognizione delle varie tipologie di esternalizzazione con le relative esigenze e principali criticità.
L’indagine si concentra in primo luogo sul trasferimento d’azienda, esaminando la normativa e la giurisprudenza europee per passare poi alla disciplina di diritto interno, alle procedure sindacali e a uno specifico focus sul trasferimento delle aziende in crisi.
Successivamente l’autore si sofferma sull’appalto, prendendone in particolare considerazione gli indici di genuinità, i criteri di distinzione dalla somministrazione illecita di manodopera e la tutela delle maestranze in caso di avvicendamento fra imprese.
Da ultimo, la ricerca approfondisce le c.d. “clausole sociali”, sia di prima che di seconda generazione, valutandone la compatibilità con il diritto eurounitario e con la costituzione nonché riflettendo sui possibili rimedi in caso di loro violazione.The author analyzes the labour consequences of the succession between entrepreneurs, starting from a recognition of the various types of outsourcing with the related needs and main critical issues.
The survey focuses primarily on the transfer of businesses, examining European legislation and case-law and then moving on to internal legislation, trade union procedures and a specific focus on the transfer of companies in crisis.
The author then dwells on the contract, taking into account in particular the indications of authenticity, the criteria of distinction from the illicit administration of labour and the protection of workers in the event of turnover between companies.
Finally, the research deepens the "social clauses", both first and second generation, assessing their compatibility with European law and with the constitution and reflecting on possible remedies in case of their violation
Dysplasic femur in total hip replacement”, Abstract from the 2013 congress of the Italian hip society
No full textSuper computers in astrophysics and High Performance simulations of self-gravitating systems
No full textThe modern study of the dynamics of stellar systems requires the use of high-performance computers. Indeed, an accurate modelization of the structure and evolution of self-gravitating systems like planetary systems, open clusters, globular clusters and galaxies imply the evaluation of body-body interaction over the whole size of the structure, a task that is computationally very expensive, in particular when it is performed over long intervals of time. In this report we give a concise overview of the main problems of stellar systems simulations and present some exciting results we obtained about the interaction of globular clusters with the parent galaxy
IL FEMORE DISPLASICO NELLA PROTESIZZAZIONE DELL’ANCA Dysplasic femur in total hip replacement
No full textBackground. Total hip arthroplasty is actually the most common
solution for the treatment of hip dysplasia. Even if the anatomical
changes of the acetabular region are more often involved in
making this procedure challenging, also the dysplasic femur hasto be considered in a precise pre-operative surgical planning.
An increase of the femoral neck anteversion togheter with an
alteration of the inclination are the most common anatomical
femoral problems. A reduction in the diameter of the medullary
canal and a straightening of the proximal medial curvature of
the femur is also described. These anatomical alterations are
worse in the presence of an hip subluxation or luxation. Challenging
in THA can arise also after femoral osteotomies.
Aims. Aim of this work is to describe, following current issues
present in literature and authors personal experience, indications
and results in total hip arthroplasty in the presence of femoral
dysplasia.
Methods. A review of the literature and a retrospective revision
of our patients that underwent total hip arthroplasties in dysplasic
hips is described.
Results. From our experience on 56 femoral stems, an uncemented
cone-shaped stem is preferred even if anatomical stems were
also used in selected patients with a good outcome.
Conclusion. Since a wide variability across the anatomical
changes is present in different individuals, an accurate preoperative
CT scanning of the proximal femur has to be taken
for making a correct decision before an hip replacement for
dysplasic anomalies

Simulations of globular clusters merging in galactic nuclear regions
No full textWe present the results of detailed N-body simulations regarding the interaction of four massive globular clusters in the central region of a triaxial galaxy. The systems undergo a full merging event, producing a sort of 'Super Star Cluster' (SSC) whose features are close to those of a superposition of the individual initial mergers. In contrast with other similar simulations, the resulting SSC structural parameters are located along the observed scaling relations of globular clusters. These findings seem to support the idea that a massive SSC may have formed in early phases of the mother galaxy evolution and contributed to the growth of a massive nucleus
Ultra Low Carbon Vehicles: New Parameters for Automotive Design
No full textAs the influence of vehicle emissions on our environment has become better understood, the UK government has recently placed urgent emphasis on the implementation of low carbon
technologies in the automotive industry through: the UK Low Carbon Industrial Strategy. The overall objective is to offer big incentives to consumers and support for the development of infrastructure and engineering solutions. This scheme however does not consider how the development of functional and experiential user value might drive consumer demand, contributing to the adoption of low carbon vehicles (LCVs) in the mass market.
With the emergence of the North East of England as the UK’s first specialised region for the development of ultra-low carbon vehicles (ULCVs), ONE North East, as a development agency for the region's economic and business development, and Northumbria University Ideas-lab have supported a project to facilitate innovation through the collaboration of technology, research and development (R&D) and business. The High Value Low Carbon (HVLC) project aims to envisage
new user value made possible by the integration of low carbon vehicle platforms with new process and network technologies. The HVLC consortium represents vehicle manufacturers and their suppliers as well as technology based companies and through an ongoing process of design concept generation the project offers a hub for innovation led enterprise.
Whilst new technological developments in areas such as power generation, nano materials, hydrogen fuel cells, printed electronics and networked communications will all impact on future automotive design, the mass adoption of low carbon technologies represents a paradigm shift for the motorist. This paper aims to describe how the mapping of new parameters will lead to new transport scenarios that will create the space for new collaborative research on user experiences supported by innovative technologies and related services
N-body simulations of Globular Cluster-like systems
No full textThe dynamics of self-gravitating globular cluster-like systems, containing N = 10(5) stars, has been simulated for 6 - 10 crossing times. We followed the evolution of three different spherical systems. The first two are quasi-virialized clusters, (with and without the presence, in the centre of mass, of a black hole); the third case regards the initial violent collapse of a spherical system.The dynamics of self-gravitating globular cluster-like systems, containing N = 10(5) stars, has been simulated for 6 - 10 crossing times.
