The restrictions enacted during lockdown to limit the spread of the novel coronavirus (SARS-CoV-2) have led to changes in people's lifestyle habits. In Italy, these restrictions have dramatically changed the way people work and spend their leisure time, also with repercussions on diet and physical activity. An anonymous survey was disseminated via ...

In the presented work, tribological interactions of tetrahedral amorphous carbon (ta-C) coatings with variations of sp3 content have been systematically studied in the boundary lubrication regime with emphasis on fatty acid-based lubricants. Manifold phenomena regarding wear and friction have been observed that exceed the conventional understanding...

AbstractThe life characteristics of Al–Si–Y and Ni–Cr–Al–Y coatings during oxidation in air at 1050°C are studied. Yttrium is shown to be absent in the solid solution of the phase components of both coatings; in the case of the Ni–Cr–Al–Y coating, yttrium, which falls into the coating as a component drop-phase sparks, negatively affects the heat re...

This study identifies the effects of transitions in caregiving status on depressive symptoms among middle-aged or older adults who care for family members with limitations in activities of daily living (ADL). Data were collected from the 2006-2018 Korean Longitudinal Study of Aging. A total of 7817 subjects were included. On the basis of their care...

The aim of this work was to monitor the mechanical behavior of 316L stainless steel produced by 3D printing in the vertical direction. The material was tested in the "as printed" state. Digital Image Correlation measurements were used for 4 types of notched specimens. The behavior of these specimens under monotonic loading was investigated in two l...

The article presents the effect of the processing parameters on tribological properties of aluminum oxide coatings Al2O3 doped with fullerene-like tungsten disulfide (IF-WS2) by design of experiment (DOE). Anodic oxidation of aluminum alloy was carried out in a ternary solution of SAS (sulfuric, adipic and oxalic acids) with IF-WS2. The thickness, ...

For the past two decades, there has been a growing interest in the application of in vitro embryo production (IVP) in small ruminants such as sheep. To improve efficiency, a large number abattoir-derived ovaries must be used, and long distances from the laboratory are usually inevitable when adult animals are used. In that scenario, prolonged sheep...

Skozi magistrsko delo najprej spoznamo poliuretane. Najprej se seznanimo z njihovo zgodovino, torej kako je prišlo do sinteze prvih poliuretanov, in nato z osnovno kemijo, predvsem poliuretanskih pen in nanosov. Po predstavitvi osnovne kemije poliuretanov so predstavljene glavne surovine, ki se uporabljajo v proizvodnjah teh polimerov (izocianati i...

Preventing bacterial colonization on scaffolds while supporting tissue formation is highly desirable in tissue engineering as bacterial infection remains a clinically significant risk to any implanted biomaterials. Elemental selenium (Se0) nanoparticles have emerged as a promising antimicrobial biomaterial without tissue cell toxicity, yet it remai...

The performances of titanium dioxide (TiO2) thin films used in photoelectrochemical applications (solar cells, water splitting, photocatalysis, etc) highly depend on their morphology and interface. In this work, we describe a straightforward strategy for designing conductive carbon-coated TiO2 porous layers allowing for the tuning of interfacial ch...
