On the effectiveness of different additives and concentrations on the re-building of the molecular structure of degraded polyethylene

2006

Mechanical recycling is an easy and economic way to re-use plastic waste as secondary materials, but, in general, their properties are worse with respect to the reclaimed materials and the virgin polymer. The aim of this work was to study the effect of concentration and reaction kinetics of two additives, an ethylene-co-glycidyl methacrylate (Lotader) and a hydroxylamine derivative (CGX), in the re-building of a degraded polyethylene. CGX is a nitroxyl radical generator able to form branching in polyolefins while the epoxy groups of Lotader can react with the functional groups present in the recycled polyethylene. The results indicate that the CGX has a higher reaction rate than Lotader, pr…

Realization of polyaspartamide-based nanoparticles and in vivo lung biodistribution evaluation of a loaded gucocorticoid after aerosolization in mice

2016

Abstract In this study, novel polymeric nanoparticles (NPs) were developed and their potential as carriers for beclomethasone dipropionate (BDP) into the lung after aerosolization was demonstrated by in vivo studies in mice. In particular, these NPs were obtained starting from two polyaspartamide-based copolymers which were synthesized by chemical reaction of α,β-poly(N-2-hydroxyethyl)- dl -aspartamide (PHEA) and its pegylated derivative (PHEA-PEG2000) with poly(lactic acid) (PLA). To obtain nanosized particles, the high pressure homogenization (HPH)—solvent evaporation method was followed by using an organic phase containing both PHEA-PLA and PHEA-PEG2000-PLA (at a weight ratio equal to 1:…

The temporal variation in Siberian flying squirrel (Pteromys volans) population size

2011

Human land use causes declines of natural populations, for example, by loss of habitat area. Additionally, habitat fragmentation can cause the population size to decline more than is expected based on the area lost. Some ecological processes, such as demographic stochasticity and Allee effect, can expose already small populations to further decline. The endangered Siberian flying squirrel (Pteromys volans) has suffered from intensive forestry in Finland. In this thesis I estimated the size and growth rate of a local flying squirrel population living in nest boxes in Alavus using 15-year mark-recapture data. I regressed the estimated population size against habitat availability to detect rel…

Comparative Genomics Between

2018

Yeasts belonging to the Saccharomyces genus play an important role in human-driven fermentations. The species S. cerevisiae has been widely studied because it is the dominant yeast in most fermentations and it has been widely used as a model eukaryotic organism. Recently, other species of the Saccharomyces genus are gaining interest to solve the new challenges that the fermentation industry are facing. One of these species is S. kudriavzevii, which exhibits interesting physiological properties compared to S. cerevisiae, such as a better adaptation to grow at low temperatures, a higher glycerol synthesis and lower ethanol production. The aim of this study is to understand the molecular basis…

Mater semper certa est ? Passé, présent, avenir d'un adage, Actes du colloque de Dijon des 24-25 novembre 2016, K. Fiorentino et A. Fiorentino (dir.)…

2018

International audience; La preuve de la filiation maternelle, résumée par l’un des adages les plus connus en droit de la famille, Mater semper certa est, a pendant longtemps semblé être une évidence voulue par la nature, donc ne posant que peu de problème juridique, à l’inverse de la paternité. Pourtant, l’évidence a-t-elle toujours été aussi flagrante ? Pourquoi ressentir le besoin de forger un adage ? Quelle fut sa valeur et a-t-il toujours parfaitement reflété la réalité ? Force est de constater que si la maternité est certaine, la preuve de celle-ci se heurte à plusieurs difficultés tant matérielles que processuelles. Il s’agit donc ici de s’interroger sur la place accordée en droit à l…

Multidimensional Prayer Inventory: Psychometric Properties and Clinical Applications

2022

Prayer is one of the most important aspects of religious/spiritual life. The psychological literature has identified various types of prayer and a few methods for measuring it. The Multidimensional Prayer Inventory (MPI) has received much attention from researchers since it allows for the capture of the most universal forms of prayer, characteristic of the Judeo-Christian tradition: Adoration, Confession, Thanksgiving, Supplication, and Reception. The aim of this article was to examine psychometric properties and clinical applications of the Polish MPI. In four studies, we established the internal structure of the MPI using Principal Component Analysis (PCA, study 1) and Confirmatory Factor…

The New Nino Capability Index for Dynamic Process Capability Analysis

2015

The process capability analysis is a crucial activity to evaluate if the process outcome meets the design specifications. Classically, such analysis is performed by verifying the in-control condition of the process and evaluating suitable capability indices, by assuming the process in-control steady-state condition. However, the in-control period of the process characterizes only a part of the system functioning cycle, the one with the lower defective rate. In particular, the system functioning cycle is also characterized by the out-of-control period, during which a greater defective rate is produced, and such increasing is not considered by the widely adopted capability indices. As consequ…

Absorption of European Funds by Romania During 2014-2020

2021

Abstract The time span between 2014 and 2020 constitutes a new, multi-annual financial framework. During this time, by negotiating with the European Union, Romania received financing through 5 major types of funds which were part of the European Structural Investments Funds (ESIF) and which were structured in six major Operational Programs, the most consistent of which is POIM - The Major Infrastructure Operational Program (MIOP). Within this financial framework, Romania needs to improve its absorption of funds based on the experience gained in the previous framework, with regards to issues like bureaucracy, corruption, lack of qualified personnel for the implementation of projects, the tra…
