Study of mechanical properties and mass transfer of agglomerated cork stoppers for sparkling wine conservation.
2019
The agglomerated cork stopper plays a key role in the preservation of sparkling wines because the gas exchanges (CO2 and O2) between the wine and the external environment depend on the stopper. The objective of this work is to determine the mechanical and barrier properties of agglomerated cork stoppers in order to identify the formulation parameters that can impact these properties, and highlight several critical points, which must be controlled during the process.The characterization of the agglomerated cork structure has revealed a large intergranular porosity, which is greatly reduced when smaller cork granules are used and when the cork is compressed in the bottleneck.The study of the …
Radial electron fluence around ion tracks as a new physical parameter for the detection threshold of PADC using Geant4-DNA toolkit
2018
International audience; The detection threshold of poly(allyl dyglycol carbonate), PADC, for C ions is determined as 55 eV/nm in stopping power, which is significantly higher than that for proton and He ions. The stopping power is not a universal parameter for expressing the detection threshold of PADC. A new physical parameter of Radial Electron Fluence around Ion Tracks, REFIT, is proposed to describe the detection threshold of PADC. It is defined as the number density of electrons passing through the surface of a cylinder of a certain radius that is co-axial with the trajectory. Furthermore, preliminary calculations are presently being performed using the Monte Carlo simulation code of G…
Atoms embedded in an electron gas: Phase shifts and cross sections
1983
The Fermi-level scattering phase shifts and the transport cross sections are reported for atoms embedded in a homogeneous electron gas. The applications of the results are discussed, using the electronic stopping power for slow ions and impurity resistivity as examples. Peer reviewed
Sustainable design: study of the life cycle assessment of the production and packaging of wine
2003
The object of the study is the identification of the factors that interact with the environment during the production and the packaging of wine. For this aim is use an Economic Input-Output Life -Cycle assessment (EIO-LCA) and I-LCA database to access both the direct and indirect effects of supply chain on the environment and economy. In this phase is examines the impact on the environment by different types of packaging, and transport, the comparisons are made analyses energy, materials consumption and emissions in the environment.
Applicability of the STOPP/START criteria to older polypathological patients in a long-term care hospital
2017
Objectives To analyse the applicability of the STOPP/START criteria as a tool to identify patients with potentially inappropriate medications (PIM) during pharmaceutical validation of prescriptions in a long-term care hospital, to identify risk factors for PIM and to characterise the physiological systems and drugs more frequently associated with these PIM. Methods An interventional, prospective and longitudinal study was conducted in polypathological patients aged >65 years. Usual pharmaceutical care and the STOPP/START criteria were used to identify PIM and to plan pharmaceutical interventions at admission. At discharge, the discharge summaries were reviewed using the STOPP/START criteria…
Progrip self-gripping mesh in Rives-Stoppa repair: Are there any differences in outcomes versus a retromuscular polypropylene mesh fixed with sutures…
2017
Highlights • The Rives-Stoppa technique is an excellent repair in midline incisional hernia. • Prospective comparative analysis between retromuscular Self-gripping mesh and PPL fixed with sutures. • Self-gripping mesh is related to less postoperative pain the first 48 h after repair. • There were more postoperative hematomas in Non-Progrip group. • There were no differences in hernia recurrence in both groups.
Early virologic response with pegylated interferons
2004
Abstract Recently, 12-week evaluation of viral response has been recommended as a means of reducing antiviral treatment morbidity and costs. The development of early stopping rules relies on an important assumption: rules must minimise discontinuation of treatment in patients who might ultimately respond after completion of the full course of therapy. Minimising loss of potential responders is the most important clinical goal in defining an early stopping rule because it provides the most sustained virological responders. This definition of the rule relies on maximising the negative predictive value. Conversely, rules that select patients based on optimising the positive predictive value pr…
Experiencing studies at the University of Joensuu - Modelling a student cohort's satisfaction, study achievements and dropping out
2001
The purpose of the study was to examine a student cohort's study experiences and emotions, satisfaction with the learning environment and changes in them during the four years of studies, on the one hand, and the influence of these factors and some background variables on learning outcomes and retention of studies, on the other. In addition, we wanted to find out how students' commitment to their studies and their study orientations influence the overall satisfaction and drop-out rates in different fields of education. The design and the problems were based on the previous research reviewed in the theoretical part and on the practical reasons to develop higher education policies. The answer…
Energeettisten protonien jarruuntuminen nestemäisessä vedessä
2011
Tämän työn tarkoituksena oli mitata protonien jarruuntumiskyky nestemäisessä vedessä energia-alueella 4 - 20 MeV. Työssä käytettiin micro channel plate -pohjaisia lentoaikailmaisimia. Lopputulosten suhteelliset virheet vaihtelivat välillä 2,0 - 16,5 % mediaanin ollessa 4,2 % ja keskiarvon 5,3 %. Saadut tulokset olivat hyvässä sopusoinnussa ICRU:n raportin numero 49 antamien simuloitujen arvojen kanssa. Energialtaan 4 - 16 MeV protonien mitatut jarruuntumiskyvyt poikkesivat noin yhden prosentin tai vähemmän simuloiduista arvoista. Energia-alueella 16 - 20 MeV protonien mitatut jarruuntumiskyvyt olivat noin 4 - 8 % suuremmat kuin ICRU:n antamat simuloidut arvot. Mitattuja arvoja verrattiin my…
Mejora de la prescripción en mayores de 65 años tras la detección de prescripciones potencialmente inapropiadas u omitidas utilizando los criterios S…
2016
Introducción: Los ancianos sufren un mayor número de patologías y utilizan un mayor número de fármacos, estando polimedicados en muchas ocasiones, por lo que lo que existe más posibilidad de tener prescripciones potencialmente inapropiadas (PPI). De hecho, hay muchos estudios donde se evidencia que en este grupo de población aparece una elevada cantidad de PPI en su farmacoterapia. Objetivos: Estudiar: el perfil de los medicamentos prescritos, la prevalencia de medicamentos UTB, PPI y prescripciones potencialmente omitidas (PPO). Analizar los posibles factores de riesgo (edad, sexo, número de fármacos prescritos y nivel de Agrupador de Riesgo Clínico) y principios activos que los provocan. …
