Short clinical crowns (SCC) ' treatment considerations and techniques

2012

When the clinical crowns of teeth are dimensionally inadequate, esthetically and biologically acceptable restoration of these dental units is difficult. Often an acceptable restoration cannot be accomplished without first surgically increasing the length of the existing clinical crowns; therefore, successful management requires an understanding of both the dental and periodontal parameters of treatment. The complications presented by teeth with short clinical crowns demand a comprehensive treatment plan and proper sequencing of therapy to ensure a satisfactory result. Visualization of the desired result is a prerequisite of successful therapy. This review examines the periodontal and restor…

Second Language Interference during First Language Processing by Arabic-English Bilinguals.

2017

The research investigated whether a bilinguals’ second language (L2) is activated during a task involving only the first language (L1). We tested the hypothesis that the amount of L2 interference can vary across settings, with less interference occurring in testing locations where L2 is rarely used. In Experiment 1, we compared language processing for 50 Arabic–English bilinguals tested in Saudi Arabia and 49 Arabic–English tested in the United States. In the task, participants viewed a picture and judged whether a phoneme presented over headphones was part of the L1 picture name. The results showed no effect of testing location on processing. For both groups of bilinguals, we observed L2 i…

Reinforcement Efficiency of Cellulose Microfibers for the Tensile Stiffness and Strength of Rigid Low-Density Polyurethane Foams

2020

Rigid low-density closed-cell polyurethane (PU) foams are widely used in both thermal insulation and structural applications. The sustainability of PU foam production can be increased by using bio-based components and fillers that ensure both enhanced mechanical properties and higher renewable material content. Such bio-based foams were produced using polyols derived from rapeseed oil and microcrystalline cellulose (MCC) fibers as filler. The effect of MCC fiber loading of up to 10 wt % on the morphology, tensile stiffness, and strength of foams has been evaluated. For estimation of the mechanical reinforcement efficiency of foams, a model allowing for the partial alignment of filler fibers…

Experimental analysis of "bovedas tabicadas"

2012

A particular type of vaulted structures, known as bóvedas tabicadas (Catalan vaults), made with alternate layers of bricks and mortar and characterized by a very low thickness in comparison to the other two dimensions, are studied. The research has been faced under the historical aspect as well as under the mechanical one, developing experimental and numerical analysis regarding real existing structures. In particular, the experimental analysis, performed by effecting compression and bending tests on samples taken from a real structure, has been devoted to the constitutive material identification and the characterization is made by considering the material as an ideal homogeneous; further e…

Real-time data processing in the ALICE High Level Trigger at the LHC

2019

At the Large Hadron Collider at CERN in Geneva, Switzerland, atomic nuclei are collided at ultra-relativistic energies. Many final-state particles are produced in each collision and their properties are measured by the ALICE detector. The detector signals induced by the produced particles are digitized leading to data rates that are in excess of 48 GB/$s$. The ALICE High Level Trigger (HLT) system pioneered the use of FPGA- and GPU-based algorithms to reconstruct charged-particle trajectories and reduce the data size in real time. The results of the reconstruction of the collision events, available online, are used for high level data quality and detector-performance monitoring and real-tim…

Career development and transitions of athletes : the International Society of Sport Psychology Position Stand Revisited

2020

This paper is a comprehensive update of the International Society of Sport Psychology (ISSP) Position Stand on career development and transitions of athletes issued a decade ago (Stambulova, Alfermann, Statler, & Côté, 2009, ISSP Position Stand: Career development and transitions of athletes. International Journal of Sport and Exercise Psychology, 7, 395–412.). A need for updating the 2009 Position Stand has grown out of the increasing inconsistency between its popularity and high citation, on the one hand, and its dated content that inadequately reflects the current status of athlete career research and assistance, on the other. During the last decade, sport psychology career scholars work…

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…

Voluntary Imitation in Alzheimer’s Disease Patients

2016

International audience; Although Alzheimer's disease (AD) primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients' behavior. The aim of the present study was to investigate whether voluntary motor imitation, i.e.…
