The Ordinance on Occupational Safety and Health in Forestry proposes no more than 4 h of effective chainsaw work daily, while EU Directive 2002/44/EC an EAV 2.5 m/s2, ELV 5 m/s2. aim this paper was to compare assess the viability proposed restrictions. A case study Croatia including 91 felled processed trees, a detailed time study, vibration magnitude measuring European beech wet wood complianc...

A tanulmány a COVID-19 világjárvány következtében megváltozott felsőoktatási körülményekhez való alkalmazkodás egy Magyarországon kevéssé ismert komplex eszközét mutatja be, amely túlmutat hagyományos válság- és változásmenedzsment-megoldásokon, távolléti oktatás pedagógiai megfontolásain technológiai támogatásán egyaránt. Az eszköz kivételesen szűk határidővel létrehozott, mégis teljes oktatói...

A new family of NASA experimental aircraft (X-planes) is being developed to uniquely, yet synergistically tackle a wide class of technologies to advance low-cost, efficient access to space for a range of payload classes. This family includes two non-air-breathing rocket-powered concepts, the X-33 and the X-34 aircraft, and two air-breathing vehicle concepts, the scramjet-powered Hyper-X and the...

The importance of recycling end-of-life vehicles (ELVs) has been widely acknowledged as a means reducing ELV waste to the environment. This reduced environmental contributes achieving number UN SDGs, including creation sustainable cities. recovery secondary resources, such metals, from ELVs also reduces over-dependence on primary resources. promotes efficient resource utilization and conservati...

The automotive industry is frequently associated with high polluting manufacturing systems, which raise concern owing to the current environmental frame. For this reason, new alternative technologies lower impact have been proposed and tested, such as additive (AM). Since AM produce almost no waste, they can represent a huge opportunity for become greener. In sense, object of present review exp...

Since electric vehicle (ELV) deployment can contribute to overall renewable energy sources, exploration of the heterogeneous influence factors (HIFs) affecting willingness accept ELVs assist in realization sustainable development goals, particularly universal access affordable for all. In this research, we explored HIFs that individuals (WAELV) within an integrated decision-making (IDM) framewo...

Abstract Waste management is gaining crucial importance as recycling aims at transforming produced waste into value for the economy. As automotive industry growing fast worldwide, end-of-life vehicles (ELVs) attracts great research attention. Due to promulgated regulations, multiple players like last owners, manufacturers, treatment centres, and municipalities require a more cooperative engagem...

BACKGROUND Heart failure is accompanied by abnormalities in ventricular-vascular interaction due to increased myocardial and arterial stiffness. Galectin-3 is a recently discovered biomarker that plays an important role in myocardial and vascular fibrosis and heart failure progression. OBJECTIVES The aim of this study was to determine whether galectin-3 is correlated with arterial stiffening ...
