Lifelong Learning in Seniors in the Perspective of the Neuro- and Psychosocial Concept
2019
Niezwykle istotne z perspektywy procesów zachodzących we współczesnym społeczeństwie jest całożyciowe uczenie się. Obecnie idea uczenia się przez całe życie, w obliczu konsekwencji starzenia się społeczeństwa, nabiera nowego znaczenia, gdzie nadrzędnym celem staję się optymalizacja aktywności społecznej oraz polepszenie jakości życia osób starszych. Proces przyswajania wiedzy związany jest z możliwościami mózgu człowieka, gdzie w wyniku starzenia się, organ ten również przechodzi fazę atrofii (starzenia się mózgu). Jednym ze sposobów przeciwdziałania tego niekorzystnego procesu jest właśnie lifelong learning, czyli całożyciowe uczenie się. Idea edukacji osób starszych aktualnie znajduje się…
A Cohesive-frictional Grain-boundary Technique for Microstructural Analysis of Polycrystalline Materials
2018
The development of a 3D microstructural model for the analysis of degradation and failure in polycrystalline materials is reviewed in the present chapter. The material is explicitly modelled at the grain level, using integral equations in conjunction with a phenomenological crystal plasticity framework for the bulk grains, and with cohesive-frictional laws to represent inter-granular micro-cracking processes. The method allows to capture the initiation, development and coalescence of damage or plasticity at the aggregate scale. The formulation’s key feature is the representation of the mechanical problem in terms of inter-granular variables only, which allows to reduce the computational cos…
Rheological Properties of Different Film Blowing Polyethylene Samples Under Shear and Elongational Flow
2005
Summary: The rheological behavior of polyethylenes ismainly dominated by the molecular weight, the molecularweight distribution and by the type, the amount and thedistribution of the chain branches. In this work a linearmetallocenecatalyzedpolyethylene(m-PE),abranchedme-tallocene catalyzed polyethylene (m-bPE), a conventionallinear low density polyethylene (LLDPE) and a low densitypolyethylene (LDPE) have been investigated in order tocompare their rheological behavior in shear and in elonga-tional flow. The four samples have similar melt flow indexand in particular a value typical of film blowing grade.The melt viscosity has been studied both in shear and inisothermal and non-isothermal elonga…
Le pont des Grilles de la Basse-Seille (fin XIVe siècle), ancienne porte d’eau de l’enceinte urbaine de Metz
2017
The bridge des Grilles de la Basse-Seille is one of the last vestiges of the medieval fortification in Metz. It is one of rare examples of fortified bridge in France. Built in the end of the 14th century, it is backfilled in 1911 and only its upper section is visible. An archaeological and historic study was made in 2011 to understand the configuration and the functioning of the bridge in the Middle Ages.
The effect of inbreeding rate on fitness, inbreeding depression and heterosis over a range of inbreeding coefficients
2014
Understanding the effects of inbreeding and genetic drift within populations and hybridization between genetically differentiated populations is important for many basic and applied questions in ecology and evolutionary biology. The magnitudes and even the directions of these effects can be influenced by various factors, especially by the current and historical population size (i.e. inbreeding rate). Using Drosophila littoralis as a model species, we studied the effect of inbreeding rate over a range of inbreeding levels on (i) mean fitness of a population (relative to that of an outbred control population), (ii) within‐population inbreeding depression (reduction in fitness of offspring fro…
COMPUTATIONAL HOMOGENIZATION OF POLYCRYSTALLINE MATERIALS WITH PORES: A THREE-DIMENSIONAL GRAIN BOUNDARY FORMULATION
2012
In this study, the influence of porosity on the elastic effective properties of polycrystalline materials is investigated using a 3D grain boundary micro mechanical model. The volume fraction of pores, their size and distribution can be varied to better simulate the response of real porous materials. The formulation is built on a boundary integral representation of the elastic problem for the grains, which are modeled as 3D linearly elastic orthotropic domains with arbitrary spatial orientation. The artificial polycrystalline morphology is represented using 3D Voronoi Tessellations. The formulation is expressed in terms of intergranular fields, namely displacements and tractions that play …
Transcranial Magnetic Stimulation Trains at 1 Hz Frequency of the Right Posterior Parietal Cortex Facilitate Recognition Memory
2021
Neuroimaging, neuropsychological, and brain stimulation studies have led to contrasting findings regarding the potential roles of the lateral parietal lobe in episodic memory. Studies using brain stimulation methods reported in the literature do not offer unequivocal findings on the interactions with stimulation location (left vs. right hemisphere) or timing of the stimulation (encoding vs. retrieval). To address these issues, active and sham 1 Hz repetitive transcranial magnetic stimulation (rTMS) trains of 600 stimuli were applied over the right or left posterior parietal cortex (PPC) before the encoding or before the retrieval phase of a recognition memory task of unknown faces in a grou…
Cīņa par varu Krievijas postimpērijas Rietumu perifērijā, 1917-1920
2015
"Cīņa par varu Krievijas postimpērijas Rietumu perifērijā (1917–1920): teorētiskās un historiogrāfiskās problēmas” ir pētīts, kā mūsdienu vēstures literatūrā ir problematizēta cīņa par varu reģionā starp Baltijas jūru un Melno jūru (Somijas, Igaunijas, Latvijas, Lietuvas, Polijas, Baltkrievijas, Ukrainas teritorijās) periodā no carisma krišanas 1917. gada pavasarī līdz Polijas un Padomju Krievijas pamiera noslēgšanai 1920. gada rudenī. Darbs ir veikts, salīdzinoši analizējot priekšvēsturi cīņai par varu Krievijas postimpērijas Rietumu perifērijā, historiogrāfijā ietvertās cīņu definējošās koncepcijas, kā arī cīņas sekas un nozīmi jeb pēcvēsturi.

Improved Maximum Strength, Vertical Jump and Sprint Performance after 8 Weeks of Jump Squat Training with Individualized Loads
2016
The purpose of the study was to determine the effects of 8 weeks of jump squat training on isometric half squat maximal force production (Fmax) and rate of force development over 100ms (RFD100), countermovement jump (CMJ) and squat jump (SJ) height, and 50 m sprint time in moderately trained men. Sixty eight subjects (~21 years, ~180 cm, ~75 kg) were divided into experimental (EXP; n = 36) and control (CON, n = 32) groups. Tests were completed pre-, mid- and post-training. EXP performed jump squat training 3 times per week using loads that allowed all repetitions to be performed with ≥90% of maximum average power output (13 sessions with 4 sets of 8 repetitions and 13 sessions with 8 sets o…
