Volar and dorsal mid-shaft forearm plating using DCP and LC-DCP: interference with the interosseous membrane and forearm-kinematics.
2010
Purpose To clarify if dorsal plate osteosynthesis of the forearm shaft is associated with impingement of the interosseous membrane (IOM) and if rotational kinematics of the forearm are influenced. Background Forearm fractures are treated by separate incisions. Osteosynthesis via one approach in proximal forearm fractures was associated with higher rates of synostosis. It has been claimed that this is due to IOM impingement. Materials and methods 16 forearms of fresh frozen cadavers were dissected until only radius, ulna and the IOM remained. To preserve physiological forearm rotation, the elbow joint, the distal radio-ulnar joint and the carpus remained intact. In group 1, LC-DC and DC plat…
Navigated percutaneous screw fixation of the pelvis with O-arm 2: two years' experience.
2020
Aim To evaluate the case series of the patients operated with percutaneous fixation by the navigation system based on 3D fluo-roscopic images, to assess the precision of a surgical implant and functional outcome of patients. Methods A retrospective study of pelvic ring fractures in a 2-year period included those treated with the use of the O-Arm 2 in com-bination with the Stealth Station 8. Pelvic fractures were classifi-ed according to the Tile and the Young-Burgess classification. All patients were examined before surgery, with X-rays and CT scans, and three days after surgery with additional CT scan. The positioning of the screws was evaluated according to the Smith score, the outcome wi…
Influence of grape transport and destemming systems on the quality of Chardonnay wines
2016
The winemaking technology plays a very important role in enology as it directly influences the characteristics of wine. In particular, grape transport and destemming are critical steps in winemaking for the wine quality. The aim of this study was to compare two different processing lines of Chardonnay grapes to evaluate their effects on the quality of the final product. In particular, grapes receiving, transporting and destemming were performed using different machines in order to evaluate their influence on the quality of Chardonnay wines. The use of a receiving hopper equipped with a belt conveyor, followed by a destemmer equipped with partially coated rubber beaters, allowed to obtain Ch…
Effectiveness of interceptive treatment of class III malocclusions with skeletal anchorage: A systematic review and meta-analysis
2017
Recently, new strategies for treating class III malocclusions have appeared. Skeletal anchorage appears to reduce the dentoalveolar effects while maximising the orthopaedic effect in growing patients. The purpose of this systematic review and meta-analysis is to examine the effectiveness of bone anchorage devices for interceptive treatment of skeletal class III malocclusions. Searches were made in the Pubmed, Embase, Scopus and Cochrane databases, as well as in a grey literature database, and were complemented by hand-searching. The criteria for eligibility were: patients who had undergone orthodontic treatment with skeletal anchorage (miniplates and miniscrews). Patients with syndromes or …
Simultaneous Vehicle and Crew Routing and Scheduling for Partial- and Full-Load Long-Distance Road Transport
2013
AbstractThis paper studies a simultaneous vehicle and crew routing and scheduling problem arising in long-distance road transport in Europe: Pickup-and-delivery requests have to be fulfilled over a multi-period planning horizon by a heterogeneous fleet of trucks and drivers. Typically, in the vehicle routing literature, a fixed assignment of a driver to a truck is assumed. In our approach, we abandon this assumption and allow truck/driver changes at geographically dispersed relay stations. This offers greater planning flexibility and allows a better utilization of trucks, but also creates intricate interdependencies between trucks and drivers and requires the synchronization of their routes…
Type II Odontoid Fracture: a case series highlighting the treatment strategies
2019
Background: A type II odontoid fracture, if unstable, can cause spinal cord damage. In this case, it is essential to choose the correct treatment—but the issues of what the correct treatment is and which of the different surgical options is best are quite controversial. In this paper we present strategies for treatment of type II odontoid fracture. Materials and Methods: Thirty consecutive cases of type II odontoid fracture were treated at the Division of Neurosurgery at Villa Sofia Hospital in Palermo (23 cases) and at the Neurosurgical Clinic, University Hospital of Palermo (seven cases), from January 2011 to August 2016. Four patients were treated with external immobilization. Twenty-six…

Making WiFi work in multi-hop topologies: Automatic negotiation and allocation of airtime
2015
We propose a solution for mitigating the performance impairments of CSMA/CA protocols in multi-hop topologies based on the dynamic adaptation of the contention process experienced by nodes in a wireless network. A distributed protocol is used to negotiate the channel airtime for a node as a function of the traffic requirements of its neighbourhood, taking into account bandwidth reserved for the control operations. A mechanism is provided for a node to tune its contention window depending on its allocated airtime. Different from previous schemes, a node's contention window is fixed in size unless the traffic requirements of its neighbourhood change. The scheme is implemented on legacy commer…
Performance analysis in sport: Contributions from a joint analysis of athletes’ experience and biomechanical indicators
2011
The purpose of this study was to test the usefulness of combining two types of analysis to investigate sports performance with the aim of optimizing it. These two types of analysis correspond to two levels of athletes’ activity: (a) their experiences during performance and (b) the biomechanical characteristics of their movements. Rowing served as an illustration, and the activity of one female crew member was studied during a race. Three types of data were collected: (a) audiovisual data recorded during the race; (b) verbalization data obtained in interviews conducted afterward; and (c) biomechanical data. The courses of experience of the two rowers during the race were reconstructed on the…
Affective, Social, and Cognitive Outcomes During a 1-Year Wintering in Concordia
2016
International audience; This study investigated time patterns and the relationships between perceived stress, recovery, control, attention lapses, and defense mechanisms (DM) during a 12-month wintering in Concordia polar station with an international crew of 14 volunteers. This ICE (Isolated, Confined, Extreme) environment induced some stress, mainly in the social dimension and showed relationships (a) between DM and both stress and recovery and (b) between recovery and perceived control, highlighting the roles of DM and control in psychological adaptation. These results offer additional insights into the affective, social, and cognitive processes involved in adaptation. The findings sugge…
