Effect of Boron Doping on the Wear Behavior of the Growth and Nucleation Surfaces of Micro- and Nanocrystalline Diamond Films

2016

B-doped diamond has become the ultimate material for applications in the field of microelectromechanical systems (MEMS), which require both highly wear resistant and electrically conductive diamond films and microstructures. Despite the extensive research of the tribological properties of undoped diamond, to date there is very limited knowledge of the wear properties of highly B-doped diamond. Therefore, in this work a comprehensive investigation of the wear behavior of highly B-doped diamond is presented. Reciprocating sliding tests are performed on micro- and nanocrystalline diamond (MCD, NCD) films with varying B-doping levels and thicknesses. We demonstrate a linear dependency of the we…

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…

Układ częściowy obejmujący wierzytelności zabezpieczone rzeczowo a zawieszenie egzekucji z mocy prawa

2018

Niniejsze opracowanie odnosi się do problematyki wpływu otwarcia przyspieszonego postępowania układowego z układem częściowym na postępowanie egzekucyjne dotyczące wierzytelności zabezpieczonej rzeczowo na składnikach majątku dłużnika. Zaprezentowany zostanie pogląd prawny, i jego uzasadnienie, według którego, w przypadku gdy wierzytelność zabezpieczona rzeczowo na majątku dłużnika zostaje objęta układem częściowym wówczas egzekucja co do niej ulega bezwzględnemu zawieszeniu z mocy samego prawa (ipso iure)

Videowikis for improved problem-based collaborative learning: Engaging information systems science students

2013

The contemporary era of social media and web 2.0 has enabled a bottom-up on-line collaborative approach with easy content creation and subsequent knowledge sharing. The technically literate students of today and the changes in pedagogy towards a user-centred approach, where learners engage in the learning process by constructing new ideas and concepts based on their current or past knowledge facilitate the use of social media in learning environments. This paper describes the combination of a wiki and screen capture videos as a complementary addition to conventional lectures in an information management and information systems development course. The basis for our approach was collaborative…

Habitat area and local habitat conditions outweigh fragmentation effects on insect communities in vineyards

2022

Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limiting the distribution and dispersal of organisms. In a full-factorial experiment of a priori selected vegetated vineyard patches of differing size and fragmentation, we aimed to disentangle the effects of habitat area (area of vegetated vineyards), habitat fragmentation (number of vegetated vineyard…

Practice for determining friction in hydraulic winch systems

2020

This paper presents a method for estimating friction in hydraulic active heave compensated (AHC) offshore winches. The method is a two-step approach where the first step is to model the friction loss in the hydraulic motors based on data from the sub-supplier. The second step requires real-life testing, where the remaining friction losses in the winch system is identified and modeled. In this context, a practice is characterized by obtaining a friction loss estimation with the highest possible accuracy over the widest possible range of operating conditions with a limited amount of experimental work. The method benefits from the use of parametric models, sub-supplier data, and real-life meas…

Discorso turistico-enologico sull’aura in ‘Un’ottima annata’ di Ridley Scott

2023

This essay follows fits into an ongoing project dedicated to highlighting the rhetorical and ideological representations of food and wine in cinema It carries out a semiotic analysis of the film A good year (by Ridley Scott, with the aim of identifying the role that wine plays in it and in the touristic imaginary about it. The essay pursues this goal by facing the issue of authenticity in tour ism as posed by Culler and by reconstructing the implicit aesthetic and touristic theory on which the film may be positioned. Then, it proceeds by getting into a reconstruction of the ideologic role played by the settings and the spaces represented in it. A spatial dialectic among city and country get…
