Modellering av virkninger p氓 skogsektoren av 酶kt bruk av skogbasert bioenergi i Europa og syd-酶stlige USA
The European Union (henceforth, EU) is now well on track to meet the 2020 targets for renewable energy production and consumption, and recently a new 2030 Framework for climate and energy has been proposed. The forest sector is supposed to make a significant contribution towards meeting green economy objectives. Moreover, it is of high interest to
analyze the potential impacts of EU鈥檚 renewable energy directive (RED 1 and the ongoing RED 2) on the forest sector in Europe and overseas.
In order to examine global challenges regarding energy, climate change, ecological impacts, technology developments and sustainable use of land and natural resources in the upcoming circular bioeconomy era (EEA 2018), improved analysis tools are required. The utilization of Forest Sector Models (henceforth, FSMs), linking forestry and forest industry activities, has been found useful for assessing the interplay between forest resources and forest commodity markets, accounting for competition and synergies between different uses of wood.
This thesis investigates the impacts of increased use of wood-based bioenergy on forest resources and markets of forest and wood products, and explores the strengths and weaknesses of FSMs.Unia Europejska (odt膮d UE) jest na dobrej drodze, aby osi膮gn膮膰 wyznaczone na 2020 rok cele w zakresie produkcji i zu偶ycia energii odnawialnej. Tak偶e ostatnio, nowe ramy klimatyczne i energetyczne zosta艂y zaproponowane na rok 2030. Zak艂ada si臋, 偶e sektor le艣ny1 ma znacz膮co przyczyni膰 si臋 do osi膮gni臋cia cel贸w zielonej gospodarki. Ponadto niezwykle istotne jest przeanalizowanie potencjalnych skutk贸w unijnej dyrektywy w sprawie energii odnawialnej (RED 1 i trwaj膮ca RED 2) na sektor le艣ny w Europie i za granic膮.
Aby zbada膰 globalne wyzwania dotycz膮ce energii, zmian klimatu, skutk贸w ekologicznych, rozwoju technologii oraz zr贸wnowa偶onego u偶ytkowania zasob贸w l膮dowych i naturalnych w nadchodz膮cej erze biogospodarki o obiegu zamkni臋tym (EEA 2018), potrzebne s膮 ulepszone narz臋dzia analityczne. Wykorzystanie modeli sektora le艣nego (odt膮d MSL), 艂膮cz膮cych dzia艂alno艣膰 w zakresie le艣nictwa i przemys艂u drzewnego, okaza艂o si臋 przydatne do oceny wzajemnych zale偶no艣ci mi臋dzy zasobami le艣nymi a rynkami surowca drzewnego, z uwzgl臋dnieniem konkurencji i synergii mi臋dzy r贸偶nymi zastosowaniami drewna.
Niniejsza praca dotyczy wp艂ywu zwi臋kszonego wykorzystania bioenergii, opartej na drewnie, na zasoby le艣ne i rynki surowca drzewnego oraz analizuje mocne i s艂abe strony MSL
The EU Bioeconomy: Supporting an Employment Shift Downstream in the Wood-Based Value Chains?
Monitoring employment in the European wood-based bioeconomy requires reliable, consistent, and comparable statistics across subsectors and over time. Statistics concerning employment in wood-based industries - the main component of the forest-based bioeconomy - must be processed carefully to cope with differences in definitions and estimation methods. In addition, specific methods must be applied to estimate wood-based employment in sectors including also non-wood activities. In this study, we first delineate the boundaries of the wood-based bioeconomy, and then create a harmonised time series on employment for the identified sectors. Finally, we estimate the share of wood-based employment along the value chain in all sectors using wood. According to the results, forestry and extended wood-based value chains employed 4.5 million people in the EU-28 in 2018. Employment in wood-based value chains decreased between 2008 and 2013 in the aftermaths of the financial crisis. Continuously decreasing employment - most apparent in the manufacture of solid wood products and pulp and paper - results from increasing productivity and a decreasing demand for graphic paper. Further, most of the wood-based employment in the EU takes place in downstream parts of value chains, although the weight of the primary sector is still high in some Eastern European countries
Modelling forest sector impacts of increased use of wood-based bioenergy in Europe and US South

Identification and In Silico Characterization of a Novel COLGALT2 Gene Variant in a Child with Mucosal Rectal Prolapse
Rectal prolapse is influenced by many factors including connective tissue dysfunction. Currently, there is no data about genetic contribution in the etiology of this disorder. In this study, we performed trio whole-exome sequencing in an 11-year-old girl with mucosal rectal prolapse and her parents and sibling. Genetic testing revealed a novel heterozygous missense variant c.1406G>T; p.G469V in exon 11 of the COLGALT2 gene encoding the GLT25 D2 enzyme. Sanger sequencing confirmed this variant only in the patient while the mother, father and sister showed a wild-type sequence. The pathogenicity of the novel variant was predicted using 10 different in silico tools that classified it as pathogenic. Further, in silico prediction, according to Phyre2, Project HOPE, I-Mutant3.0 and MutPred2 showed that the missense variant can decrease protein stability and cause alterations in the physical properties of amino acids resulting in structural and functional changes of the GLT25D2 protein. In conclusion, the present study identifies a previously unknown missense mutation in the COLGALT2 gene that encodes the enzyme involved in collagen glycosylation. The clinical features observed in the patient and the results of in silico analysis suggest that the new genetic variant can be pathogenic
