Clinical Behavior of Ceramic, Hybrid and Composite Onlays. A Systematic Review and Meta-Analysis
2020
A systematic review and meta-analysis was performed to analyze the survival of onlay restorations in the posterior region, their clinical behavior according to the material used (ceramic reinforced with lithium disilicate, conventional feldspathic ceramic or reinforced with leucite; hybrid materials and composite), possible complications, and the factors influencing restoration success. The systematic review was based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) statement, without publication date or language restrictions. An electronic search was made in the PubMed, Scopus, Embase, and Cochrane databases. After discarding duplicate publications and stu…
Clinical Behavior of Short Dental Implants: Systematic Review and Meta-Analysis
2020
Short implants are an increasingly common alternative to other surgical techniques in areas where bone availability is reduced. Despite the advantages they offer, a variety of biological repercussions have been described in the literature that can even lead to the loss of these. The aim of this systematic review and meta-analysis was to analyze the impact of the use of short implants on their survival and on peri-implant bone loss, evaluating the influence that length, diameter, and crown-to-implant ratio (C/I) have on these parameters. This systematic review was based on guidelines proposed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). An electronic se…
Particle tracking in a gap of aquatic vegetation meadow
2009
Aquatic vegetation considerably affects the flow field in water bodies, with influence increasing as the depth decreases. As a consequence, vegetation also affects suspended particle transport. In inshore sandy beds less than 40 m deep of the Mediterranean Sea, meadows of Posidonia oceanica are widespread. This plant is constituted by a tuft of very thin and flexible ribbon-like leaves about 1 cm wide and up to 1.5 m long; the meadow areal density can reach 1000-1200 plant/m2. Frequently, such meadows are not continuous but vegetated areas alternate with sand strips (“gaps”). The presence of such discontinuities noticeably affects the flow field and gaps can actually act as particle traps. …
Forming ideal public-private partnerships for export practices : case exporting Resource Wisdom
2017
Vaikuttavien julkisen ja yksityisen sektorin vientikumppanuuksien muodostaminen : tapaustutkimus: Resurssiviisaus vientituotteeksi. Väestönkasvu ja urbanisaatio luovat kestävyyshaasteita, mutta myös mahdollistavat uuden liiketoiminnan ja kestävän kehityksen esiinmarssia. Tämä Pro gradu –tutkielma tarkastelee, miten kestävän aluekehityksen mallia, Resurssiviisautta, voidaan hyödyntää suomalaisten yritysten vientitukena julkisen ja yksityisen sektorin yhteistyöllä. Tutkimus keskittyy tämän yhteistyön muodostamiseen, sen johtamiseen ja ohjaamiseen kuin myös oikeaoppiseen yhteistyön hallinnointiin. Näitä aspekteja tarkastellaan etenkin kaupallisessa vientitarkoituksessa. Pro gradua varten haast…
Les outils d'intelligence territoriale pour les acteurs de terrain à Seraing: entre appropriation des méthodes et acquisition de compétences
2005
Asbl Optim@ leads an experience of participative observation in Seraing since 1998. The complexity of the problems met by the population and the professional division into sectors justified this participative approach. This one concerns the economic, social and human global nature of the territory. It leans on a wide partnership of local actors: professionals, inhabitants and decision-makers. It uses at this end the method of territorial intelligence CATALYSE created by the research team ThéMA-MTI and developed with numerous members of the REIT. The results obtained in terms of interdisciplinary dialogue between inhabitants, professionals and decision-makers; allow identifying axes about th…
Sustainable Fertilization in Medicinal and Aromatic Plants
2015
The nutrient level in the soil is one of the most investigated aspects of agricultural research, also including research into Medicinal and Aromatic plants. The effect of fertilization has been studied in detail for many species, with contrasting results as concerns above all the qualitative aspects of production. Generally speaking, an increased level of nutrients induces an enhancement of plant biomass, but when the goal of cultivation is different from herbage yield, i.e. when a special plant part (seeds, or roots, or flowers) is of interest, or when the quality features are especially important, the outcome of fertilization may be dramatically different. A fine-tuned fertilization pract…
What Can You Achieve in Eight Years? : A Case Study on Participation, Effectiveness, and Overall Impact of a Comprehensive Workplace Health Promotion…
2019
Objective: To investigate participation and effectiveness of a multiyear comprehensive workplace health promotion (WHP) program. Methods: Participation and effectiveness data came from employer and vendor systems. Health data came from health risk assessments (HRA) and biometric screenings. Participation and effectiveness were analyzed using descriptive analyses, T-tests and Mann-Whitney U tests where appropriate. Overall impact was assessed using the PIPE Impact Metric. Results: 86% of employees completed the HRA and 80% the biometrical screenings. Annual participation rate was 24%, and total reach was 58%. The portion of successful participants was 23% in 2010–2013 and 18% in 2014–2017. P…
Balitsky-Kovchegov equation
2011
In high-energy particle physics the energy evolution of various quantities can be calculated from the Balitsky-Kovchegov (BK) equation. Depending on the frame that is used to describe the process, the BK equation can be seen to describe either the energy evolution of the virtual photon wave function or the gluon distribution function of a hadron. In this work the BK equation is derived at leading logarithm accuracy from QCD and solved analytically in some special cases. In order to derive it the quantum field theory on the light cone is introduced. Part of the higher order corrections to the BK equation, namely the running strong coupling constant and the kinematical constraint effects, are…
Stationary and Nontationary Response Probability Density Function of a Beam under Poisson White Noise
2011
In this paper an approximate explicit probability density function for the analysis of external oscillations of a linear and geometric nonlinear simply supported beam driven by random pulses is proposed. The adopted impulsive loading model is the Poisson White Noise , that is a process having Dirac’s delta occurrences with random intensity distributed in time according to Poisson’s law. The response probability density function can be obtained solving the related Kolmogorov-Feller (KF) integro-differential equation. An approximated solution, using path integral method, is derived transforming the KF equation to a first order partial differential equation. The method of characteristic is the…
