Anticipatory Postural Adjustments and kinematic arm features when postural stability is manipulated

2018

International audience; Beyond the classical paradigm that presents the Anticipatory Postural Adjustments (APAs) as a manner to create forces that counteract disturbances arising from the moving segment during a pointing task, there is a controversial discussion about the role APAs to facilitate the movement and perform a task accurately. In addition, arm kinematics features are classically used to infer the content of motor planning for the execution and the control of arm movements, The present study aimed to disentangle the conflicting role of APAs during an arm-pointing task in which the subjects reach a central diode that suddenly turns on, while their postural stability was manipulate…

Development of an immunochromatographic assay based on carbon nanoparticles for the determination of the phytoregulator forchlorfenuron

2013

Rapid analytical methods enabling the determination of diverse targets are essential in a number of research areas, from clinical diagnostics to feed and food quality and safety. Herein, the development of a quantitative immunochromatographic assay for the detection of the synthetic phytoregulator forchlorfenuron (CPPU) is described. The competitive lateral flow immunoassay (LFIA) was based on the immobilization onto a nitrocellulose membrane of an ovalbumin-CPPU conjugate (test line) and on the use of an immunodetection ligand consisting of carbon nanoparticles labeled with an anti-CPPU monoclonal antibody through interaction with a secondary antibody. The presence of CPPU in horticultural…

The mechanically based non-local elasticity: an overview of main results and future challenges

2013

The mechanically based non-local elasticity has been used, recently, in wider and wider engineering applications involving small-size devices and/or materials with marked microstructures. The key feature of the model involves the presence of non-local effects as additional body forces acting on material masses and depending on their relative displacements. An overview of the main results of the theory is reported in this paper.

Kinetics of phase separation in thin films: Lattice versus continuum models for solid binary mixtures

2008

A description of phase separation kinetics for solid binary (A,B) mixtures in thin film geometry based on the Kawasaki spin-exchange kinetic Ising model is presented in a discrete lattice molecular field formulation. It is shown that the model describes the interplay of wetting layer formation and lateral phase separation, which leads to a characteristic domain size $\ell(t)$ in the directions parallel to the confining walls that grows according to the Lifshitz-Slyozov $t^{1/3}$ law with time $t$ after the quench. Near the critical point of the model, the description is shown to be equivalent to the standard treatments based on Ginzburg-Landau models. Unlike the latter, the present treatmen…

Anatomiczny spektakl w dawnej poezji erotycznej

2016

Artykuł stanowi próbę deskrypcji dawnych zabiegów medycznych, takich jak sekcja zwłok, w kontekście kulturowo-literackiego wydarzenia popularnego w XVI- i XVII-wiecznej Europie. W tekście przywołano genezę padewskich spotkań o charakterze theatrum anatomicum, z dokładnym opisem najważniejszych rytuałów, procedur oraz okoliczności w ich organizowaniu. Autorka, korzystając z bogatego studium Anny Wieczorkiewicz Muzeum ludzkich ciał oraz szkiców autorstwa Radosława Grześkowiaka zatytułowanych Amor Curiosus. Szkice o osobliwych tematach dawnej poezji erotycznej, buduje swój wywód na użytej w tych pozycjach naukowych nazwie „spektakl anatomiczny”. Pozwala to na zgłębienie dychotomii sensu tychże…

Univariate and multivariate properties of wind velocity time series

2009

We analyze the time series of hourly average wind speeds measured at 29 different stations located in Sicily, a region with a complex morphology. The investigation, performed from the univariate as well as the multivariate point of view, evidences that the statistical properties of wind at the single sites have features that are not reproduced by standard models and, thus, require specific modeling. Moreover, the synchronous evolution of wind velocity presents a cluster structure, obtained with different algorithms, that persists in the standard deviation too.

Wolność pracy jako przesłanka ograniczająca swobodę kontraktowania - wybrane problemy

2022

Zgodnie z art. 65 ust. 1 Konstytucji RP każdemu zapewnia się wolność wyboru i wykonywania zawodu oraz wyboru miejsca pracy. Wpływ wyrażonej we wskazanym przepisie wolności pracy na swobodę kształtowania umownych stosunków pracy jest wciąż otwartym polem do dyskusji prawniczej. W prezentowanym tekście autorzy zmierzają do rozstrzygnięcia, czy zasada wolności pracy może zostać uznana za przesłankę ograniczającą swobodę kontraktowania. Zagadnienie to, mające charakter dogmatyczny, poddane zostało analizie systemowej. Autorzy przyjmują, że z perspektywy stosunków prywatnoprawnych wolność pracy należy ujmować jako element obiektywnego, preferowanego porządku wartości społeczno-gospodarczych (zas…

Low mimosine content and nutrient-rich foliage of two Leucaena leucocephala varieties: a potential fodder resource in Mediterranean agroforestry syst…

2022

Leucaena leucocephala is worldwide used for wood production, reforestation and for feeding livestock. To assess the potential use of leucaena for animal nutrition, we analysed the composition of methanolic extracts of leaf samples of two varieties occurring in Sicily (Mediterranean area), also determining the presence of mimosine.
