Optimization of the characteristic angles of both front and rear McPherson suspensions on a circular track using multi-body numerical simulation
2009
The research reported in this paper aims to simulate the road-holding of a virtual vehicle using multi-body simulation to estimate both the contact forces between the tyre and ground and the roll motion when cornering. Furthermore, the effect of the characteristic angles on the variation in the forces of the tyre in contact with the ground is studied to determine optimal values for these angles. Emphasis is placed on an average-class vehicle, of which both the external dimensions and mass are chosen appropriately, with a McPherson suspension mounted on both the front and the rear. The characteristic values of the camber and toe-in angles, in both the front and the rear, are optimized for m…
L'ANTICO CAMPANILE DELLA CATTEDRALE DI LECCE IN UN CONSULTO DEL 1574
2016
L'antico campanile della cattedrale di Lecce si trovava in una posizione diversa rispetto a quello esistente costruito nel 1658. La maestosa torre, con cinque ordini e una terminazione a corona, era collocata di fianco all'antica facciata principale della chiesa, sul lato sinistro. Nel 1574 a causa di numerosi crolli, gli amministratori della chiesa decisero di avvalersi del parere tecnico di tre professionisti: Padoano Schiero, Padoano Baxi e Gabriele Meschinello, chiamati ad esprimersi in merito alla pericolosità di tali crolli e allo stato della torre. Vennero prodotte tre relazioni tecniche i cui contenuti illustravano la necessità di demolire la torre al fine di scongiurare eventuali d…

Incidence, Medical Resource Utilisation and Costs of Hyperuricemia and Tumour Lysis Syndrome in Patients with Acute Leukaemia and Non-Hodgkin's Lymph…
2003
Hyperuricemia (HU) and tumour lysis syndrome (TLS) are complications of acute leukaemia and non-Hodgkin lymphoma (NHL) leading to increased morbidity and mortality. The objective of this study was to define incidence and calculate health care cost associated with HU and TLS. 788 acute leukaemia and NHL patients from Belgium, The Netherlands, Spain and UK were screened retrospectively for HU and TLS. Resource use related to HU and TLS was recorded and costs were calculated applying local unit costs. Results showed that HU occurred in 18.9% of patients, and 27.8% of them fulfilled TLS criteria. The cost of HU without TLS was 672 euros (SE 181), the cost of TLS 7,342 euros (SE 1,412). TLS requ…
Survey of Fertility Preservation Options Available to Patients With Cancer Around the Globe
2020
Purpose Oncofertility focuses on providing fertility and endocrine-sparing options to patients who undergo life-preserving but gonadotoxic cancer treatment. The resources needed to meet patient demand often are fragmented along disciplinary lines. We quantify assets and gaps in oncofertility care on a global scale. Methods Survey-based questionnaires were provided to 191 members of the Oncofertility Consortium Global Partners Network, a National Institutes of Health–funded organization. Responses were analyzed to measure trends and regional subtleties about patient oncofertility experiences and to analyze barriers to care at sites that provide oncofertility services. Results Sixty-three res…
On the Use of the Eddy Covariance Latent Heat Flux and Sap Flow Transpiration for the Validation of a Surface Energy Balance Model
2018
Actual evapotranspiration is assessed via surface energy balance at an hourly rate. However, a robust estimation of daily evapotranspiration from hourly values is required. Outcomes of surface energy balance are frequently determined via measures of eddy covariance latent heat flux. Surface energy balance can be applied on images acquired at different times and spatial resolutions. In addition, hourly actual evapotranspiration needs to be integrated at a daily rate for operational uses. Questions arise whether the validation of surface energy balance models can benefit from complementary in situ measures of latent heat flux and sap flow transpiration. Here, validation was driven by image ac…
Evaluation of Small Vase and Y-trellis Orchard Systems for Peach and Nectarine Production in Mediterranean Regions
2015
Two peach planting systems, Small Vase (SV) and Y-trellis (Y), were evaluated and compared in the Mediterranean settings of Southern Italy. The two orchards were located next to each other on relatively uniform soil and terrain, and the observations included two peach (âRich Mayâ and âSummer Richâ) and two nectarine (âBig Bangâ and âNectarossâ) cultivars. In the SV system, trees were spaced at 4.5 A 2.5 m (888 trees/ha), whereas in the Y system, trees were spaced at 5.5 A 2 m (909 trees/ha) and no canopy gap was left between rows. Yield per tree; fruit size grade; unit price of sold peaches for each size grade; materials, labor and associated costs for cultural management;…
An integrated approach for high spatial resolution mapping of water and carbon fluxes using multi-sensor satellite data
2012
In the last years, modeling of surface processes - such as water, energy and carbon budgets, as well as vegetation growth- seems to be focused on integrated approaches that combine aspects of hydrology, biology and meteorology into unified analyses. In this context, remotely sensed data often have a core role due to the cross-cutting impact of this novel source of spatially distributed information on all these research areas. However, several applications - such as drought monitoring, yield forecasting and crop management - require spatially detailed products at sub-field scales, which can be obtained only with support of adequately fine resolution remote sensing data (< 100 m). In particul…
Construction sequence analysis of long-span cable-stayed bridges
2018
Abstract In cantilever construction of long-span cable-stayed bridges the stressing sequence of stays is fundamental for establishing the final configuration of the bridge. The structural behaviour of these bridges is usually evaluated through a forward staged construction analysis, in which the values of the prestressing forces to be applied to stays are the main unknowns. A unified procedure for determining the initial cable forces and for analyzing the entire sequence is presented here, considering the geometric nonlinearity of stays through the Dischinger equivalent elastic modulus. The target is the simultaneous determination of the initial cable forces with the simulation of the const…
