In Vitro Study on Bone Heating during Drilling of the Implant Site: Material, Design and Wear of the Surgical Drill
2020
Objective: An in vitro study was made to compare mean thermal variation according to the material, design and wear of the surgical drills used during dental implant site preparation. Material and methods: Three study groups (stainless steel drills with straight blades
COVID‐19 in older adults: What are the differences with younger patients?
2020
Aim The present study aimed both to gain knowledge on the distinctive clinical characteristics of older adults with coronavirus disease 2019 (COVID‐19), in comparison with those of younger patients, and to identify risk factors for mortality. Methods A retrospective observational study was carried out of patients consecutively admitted to Doctor Peset University Hospital, Valencia (Spain) for COVID‐19 from 11 March to 28 April 2020. Every case was diagnosed by reverse transcription polymerase chain reaction or by serology test to detect antibodies. Demographic details, clinical characteristics, laboratory findings on admission and complications of each case were collected from electronic me…
Comptabilité à base d'activités (ABC) et activités informatiques : une contribution à l'amélioration des processus informatiques d'une banque
2010
The aim of the paper is to describe the Activity-based Costing and Management methods applied in France. For that purpose, we use a literature review and a case study. In a first time, we analyse the origins of the methods and their diffusion. Then we present the French situation. Finally, we propose a case study that takes place in a French bank. Our paper shows that the ABC and ABM methods are as developed in France as in the Anglo-Saxon countries and that the methods are strategically oriented.
Perceived goal setting practices across a competitive season
2019
Goal setting is an effective and frequently used tool for performance enhancement in sports. However, in the previous studies, the focus has been on goal effectiveness among individual male athletes and at one point in time. Therefore, the purpose of this longitudinal study was to examine goal setting practices in women’s sport teams across a competitive season from players’ individual and team perspectives. A total of 146 female players representing 24 teams in ice hockey, ringette, or floorball completed three online surveys. Surveys focused on setting outcome, process, and performance goals, as well as evaluating the follow-through of setting goals and actually reaching these goals acro…

Going through the lockdown: a longitudinal study on the psychological consequences of the coronavirus pandemic
2021
Coronavirus 2019 pandemic lockdown in Italy lasted for 2 months, 1 week and 2 days. During this long period, one of the longest in Europe, the restrictions produced effects on people’s psychological well-being, with consequences that also continued after lockdown. The purpose of the study is to investigate these effects and how they changed in the general population over a period of time. We are also interested in exploring people’s post-lockdown anxiety and concerns. We conducted an online survey using snowball sampling techniques. The longitudinal study consisted of four administrations covering a period of 10 weeks between April (baseline) and June (last follow-up). Levels of anxiety and…

The interactive effects of various nitrogen fertiliser formulations applied to urine patches on nitrous oxide emissions in grassland
2017
AbstractPasture-based livestock agriculture is a major source of greenhouse gas (GHG) nitrous oxide (N2O). Although a body of research is available on the effect of urine patch N or fertiliser N on N2O emissions, limited data is available on the effect of fertiliser N applied to patches of urinary N, which can cover up to a fifth of the yearly grazed area. This study investigated whether the sum of N2O emissions from urine and a range of N fertilisers, calcium ammonium nitrate (CAN) or urea ± urease inhibitor ± nitrification inhibitor, applied alone (disaggregated and re-aggregated) approximated the N2O emission of urine and fertiliser N applied together (aggregated). Application of fertili…
On a nonlinear Schrödinger equation for nucleons in one space dimension
2021
We study a 1D nonlinear Schrödinger equation appearing in the description of a particle inside an atomic nucleus. For various nonlinearities, the ground states are discussed and given in explicit form. Their stability is studied numerically via the time evolution of perturbed ground states. In the time evolution of general localized initial data, they are shown to appear in the long time behaviour of certain cases.
