Updated Italian checklist of Tenuipalpidae with description of a new species and new worldwide records of the genus Cenopalpus (Pritchard et Baker)
No full textThe family Tenuipalpidae includes agricultural pests that have garnered extensive attention from the global research community. Despite the economic importance of tenuipalpids, due to their ecology and global trade of the infested plants, there has not been any corresponding and comprehensive research on these mites in Italy in recent decades. This study aimed to determine the species composition of tenuipalpid mites in Italy, update the Italian checklist for the taxon, and include new records and host plant associations of the genera Brevipalpus Donnadieu and Cenopalpus Pritchard and Baker worldwide. The study found several new records of tenuipalpid species in Italy, including four Cenopalpus and two Brevipalpus species. Additionally, one new species Cenopalpus ulmifolius De Giosa, Ochoa et de Lillo was added to the list. The research also incorporated new records of Cenopalpus species in different countries and several new host plant associations and the description of novel taxonomic characters were present for the Cenopalpus species studied during this work, since they were the most abundant tenuipalpid collected in the sampled areas. The study’s findings are crucial for developing effective management for tenuipalpid mites, understanding the fauna composition, and constructing preparedness strategies for quarantine purposes

Topology Optimization of a Femoral Stem in Titanium and Carbon to Reduce Stress Shielding with the FEM Method
No full textArthroplasty is commonly performed to treat advanced osteoarthritis or other degenerative
joint conditions; however, it can also be considered for young patients with severe joint damage that
significantly limits their functionality and quality of life. Young patients are still at risk of aseptic
mobilization and bone resorption due to the phenomenon of stress shielding that causes an uneven
distribution of tensions along the femoral contact surface prosthesis. This phenomenon can be limited
by choosing the material of the prosthesis appropriately or by varying its stiffness, making sure that
its mechanical behavior simulates that of the femur as much as possible. The aim of this study is to
evaluate the mechanical strength of a prosthesis optimized both in shape and material and compare
the results with a standard titanium prosthesis. Methods: Through three-dimensional modeling
and the use of finite element method (FEM) software such as ANSYS, the mechanical behavior of
traditional prosthesis and prosthesis optimized topologically respecting the ASTM F2996-13 standard.
Results: With topological optimization, there is a stress reduction from 987 MPa to 810 MPa with a
mass reduction of 30%. When carbon fiber is used, it is possible to further reduce stress to 509 MPa.
Conclusions: The reduction in stress on the femoral stem allows an optimal distribution of the load
on the cortical bone, thus decreasing the problem of stress shielding
Stochastic modelling and statistics of polymer crystallization process
No full textCrystallization of polymers is modelled as a spatially structured process consisting of a nucleation phase and a growth phase. A counting process approach together with methods of stochastic geometry leads us to the evolution equations of the relevant quantities of the process. In particular we provide local and global convergence of the stochastic growth process to its expected value, thus justifying the use of deterministic models to predict the results of real experiments. Estimates of the relevant parameters of the process are obtained via the maximum likelihood method, and also by a nonparametric method based on the estimation of the hitting function of the associated Boolean model. Asymptotic properties of the estimators are given and computer experiments are reported to show their qualitative behaviour, as a function of the available volume and of time
Conventional data display and implications for the interpretation of seismic profiles: a discussion on the ViDEPI seismic database offshore Apulia (southern Italy)
No full textThe present paper analyses old seismic profiles and exploration well logs, from the marine zones B, D and F (offshore the Apulia region, southern Italy), included in the Visibility of Petroleum Exploration Data in Italy (ViDEPI) project. The public seismic profiles available from this project present several limitations since basic information for an accurate geological interpretation are missing, such as the basic shape of the seismic wavelets and the seismic polarity. In this study, a review of the basic pulse shape and polarity of seismic wavelets, as well as the shape and polarity of principal reflectors, has been addressed. With the purpose of revealing the shape and polarity of the seismic profiles from the marine zones B, D and F, the seismic pattern of the reflectors at the sea floor has been analysed. Finally, lithostratigraphic and sonic logs have been used to identify abrupt interval velocity variations between different lithostratigraphic successions, resulting in a geological meaning of the principal reflectors
Basic data visualization in vintage seismic profiles: indications for the interpretation of the ViDEPI database (offshore Puglia, southern Italy)
No full textThe Visibility of Petroleum Exploration Data in Italy (ViDEPI) project represents a freely accessible valuable resource for the research community. However, seismic profiles available from this project present several limitations because information such as the basic shape of the seismic wavelets and the seismic polarity are not available. In this study, using subsurface (i.e., 2D seismic profiles) data related to the Marine Zones B, D and F (offshore Puglia) a review of the basic pulse shape and polarity of seismic wavelets, as well as the shape and polarity of principal reflectors has been addressed. Moreover, borehole data (i.e., lithology and sonic logs) have been used to identify abrupt average velocity changes linked to different lithostratigraphic successions recorded as dominant high-amplitude reflectors
