Welding metods of wood and wood panels
, 2015 Zavarivanje drva je jedna od novijih disciplina čiji je cilj spajati drvo i drvne ploče bez upotrebe ljepila ili nekog drugog vezivnog sredstva. Zavarivanjem dolazi do povećanja temperature koje se javlja kao posljedica trenja i tlaka.

Australian Journal of Politics &History, EarlyView.ABSTRACT This article explores Australian media commentary on white Rhodesians migrating to Australia, focusing on the period of Malcolm Fraser's prime ministership (1975–1983). The main argument is that the Australian media debates about whether to classify white Rhodesians as ‘migrants’ or ‘refugees’ were not merely semantic but reflected a deeper ...

Occupational exposure to metal welding and cataract: A systematic review and meta‐analysis
Acta Ophthalmologica, EarlyView.Abstract Background Metal welding generates ultraviolet radiation (UVR) of cataractogenic wavelengths, and UVR emitted during welding has been associated with cataract formation, but results from prior studies are conflicting. Methods We conducted a systematic review and meta‐analysis of epidemiological studies addressing associations between ...

Chemical investigations on the thermal behaviour of wood during friction welding
Friction welding is a new technology in the course of which wood pieces are subjected to circular or linear movements in a welding machine. The wood in the contact zone is heated and melted.

Influence of the Depth of Friction-welded Dowels on the Strength of Rotary Welded Joints
BioResourcesOne of the important factors in rotary welding is the depth of welding of the dowel as well as the direction of welding of the dowel. In the studied interval (welding depth of 15 to 30 mm), the pull-out force increased when welding the dowel parallel to ...

The development of iron British piers in the XIX century. The discovery of new materials
Materiales de Construccion, 2011 In this article, the authors study the decadence of wood piers along XIX century, mainly because of problems inherent to the attacks of invertebrates. Soon, the wood structures will be substituted by iron ones, appearing two extraordinary materials, cast

When Jobs Change: Skills Mismatch and the Value of Training
British Journal of Industrial Relations, EarlyView.ABSTRACT This article examines the impact of rapidly changing skill requirements on skills mismatch in Europe and the role of training in mitigating adverse effects. Using data on approximately 70 million online job vacancies, we estimate the extent to which occupational skill requirements changed between 2019 and 2023 across European Union (EU ...
