The efficiency of grading classes and strength classes was compared, depending on the type of log from which the material was obtained. Evaluating the strength properties of structural timber produced in Poland by means of visual grading, as well as tests of mechanical properties can determine the distribution of specimens according to strength classes. The research results may contribute to a more rational selection of round timber in terms of its anticipated structural applications.

Besides, the effect of the technical-technological parameters, namely, feed speed and depth of cut on the particle size distribution, was also investigated, By Richard Kminiak, Lubos Kristak and Roman Reh, Technical University in Zvolen, Martin Kučerka and Alena Očkajová, Matej Bel University, Petar Antov, University of Forestry in Bulgaria, Tomasz Rogoziński, Poznan University of Life Sciences, Marta Pędzik, Poznan University of Life Sciences and Wood Technology Institute in Poland

Professional software solutions such as AutoPanelSizer help to minimise waste and optimise workflows. By Thomas Reuke, senior software developer, Fraunhofer SCAI

Quantitative data were collected in a survey of robotised production line operators working in the furniture sector in Lithuania. As predicted, the results revealed that job insecurity had a negative impact on happiness at work as a higher-order construct and all of its dimensions.

In connection with the results obtained, the improved technology for the production of furniture boards for the manufacture of moisture-resistant wood products is proposed.

Much of the work has been completed in conjunction with the U.S. Department of Agriculture, Forest Service, Forest Products Laboratory as well as the Agricultural Research Service with the overall intent of improving lumber and wood products standards and valuation. Thus, the future impact of NDE needs to be strengthened. By R Dan Seale, Rubin Shmulsky and Frederico Jose Nistal Franca, Forest and Wildlife Research Center, Mississippi State University
Read more...The built environment is one of the greatest contributors to carbon emissions, climate change, and to the unsustainable pressure on the natural environment and its ecosystems. The use of more timber in construction is one possible response, but a global encouragement of such a strategy raises some difficult questions. Existing evidence points indeed towards timber as the lower carbon option when modelled through life cycle assessment without having to draw on arguments around carbon storage, although issues remain. By Jim Hart and Francesco Pomponi, Edinburgh Napier University

These days, one must also consider market conditions and must be prepared to face the worst due to COVID 19 pandemic. There still seems to a lot of scope left for the improvisation and development of the Edge materials, machine design, quality, workability, feasibility and various other aspects involved in the trade.

In addition, the association of CP to process flows would be a preventive measure leads to a new connection between process optimisation and environmental performance.

However, the economic value of how site-specific ecological conditions interact with other functions provided by the forest. As a result, a numerical discrete dynamic optimisation model was constructed to estimate the economic value of site quality, taking into account its interaction with timber value and carbon sequestration, in Swedish forests.
