Microscopic Study on the Composites of Wood and Polypropylene*1
「森林総合研究所研究報告」(Bulletin of FFPRI),Vol. 1, No. 1 (No.382), 115-122, March, 2002 論 文(Original Article) Microscopic Study on the Composites of Wood and Polypropylene*1 FUJII Tomoyuki*2 and QIN Te-fu *3 Abstract Optical and scanning electron microscopies coupled with a thin-sectioning method and a chemical treatment to remove cell wall material were adopted to investigate morphologically the dispersion of wood fillers and the interface between the wood and polypropylene (PP) matrices in injection-molding composites. Wood fillers were well dispersed in PP matrix with a tendency toward longitudinal and concentric orientation. The interface between wood and PP was well illustrated by the chemical digestion method. It was demonstrated with this method that PP can penetrate into macro-cavities such as fiber lumina inside wood particles through cracks of inter- and intra-wall fractures and comprises a three-dimensional network within the particles and also connecting to PP matrix outside. Wood fillers were always completely isolated and covered by PP probably owing to their high wetability at their interface, although this did not directly result in stiff chemical bonding. This suggests that the chemical bonding of wood fillers and PP matrix is more important for the improvement of the adhesion properties than the surface compatibility. Keywords: composite wood, polypropylene, morphology, SEM, optical microscopy Introduction is that the resulting composites usually have a significantly reduced impact and tensile strength due to poor adhesion There has recently been a dramatic increase of interest between the hydrophilic filler material and hydrophobic in using biomass such as wood fibers, oil palm fibers and thermoplastic. -

Internationales Holzbau-Forum IHF 2017 Overview of Baltic Forest and Wood Industry | I. Erele, H. Välja, K. Klauss 3 Overview of Baltic Forest and Wood Industry We can certainly call Baltic states the land of forests. Almost every inhabitant is related to forest, forestry and forest products in one or another way. Since long ago wood has been used in heating, construction, production of furniture and other household items. Today forest sector and its wood processing industry have developed into one of the most important sectors of the regional economy. And despite the fact that it occupies only 4,1% of the EU's territory, the commercial forest stock accounts for 6,3% of the EU. Forest has deep roots into Baltic States culture traditions, as well as provides opportunities for spending free time in forest hunting, in sports activities or picking berries and mush- rooms. And furthermore, there are large nature values in our forests that in some cases are unique not only on European, but also global level. However, it’s not an opportunity because it’s simply here. The forest that grows by itself represents beautiful nature values, but it becomes „the green gold” because we have learned to use and manage it wisely – by protecting nature values, by securing resources for national growth and contributing to the wellbeing of our society. -
Wood Industry Report
Wood Industry Report Submitted by Tim Jenks Prosperity Region 3 Wood Industry Proposed Five Year Action Plan Introduction The Wood Products Industries form a broad sector of business activity in Northern Michigan, and particularly in the eleven counties of Region 3. An MSU Extension study in 2012 described the forest industry as “Michigan’s third largest manufacturing sector,” supporting “about 136,000 jobs and adding $17 billion to Michigan’s economy.” (MSUE, 2012) While timber harvests could increase somewhat above their current levels, the greatest opportunity for economic growth lies in the added value provided by manufacturing wood products. Timber harvest, sawmill operations, and wood products manufacturing represent traditional industries for the people of this area of Michigan. The sector offers long- term sustainability, opportunities for positive environmental impact, and lifestyle compatibility. The actions proposed in this section will work to stabilize and maintain the existing industry, as well as to promote the establishment and growth of new entrepreneurial businesses. Overview of the Wood Products Industry Sector The “Wood Industry” sector includes a supply chain of related goods and services, ranging from harvesters to cut the trees to skilled crafts who create finished products. In addition, the sector supports large trucking operations, heavy equipment for harvesting and loading, maintenance services, and other support businesses. Harvesters Harvesters comprise a number of small businesses with a large investment in capital equipment. They sometimes own “tree farm” land, but more often bid on contracts to cut timber, either in behalf of a sawmill, or to sell independently to a sawmill. Northern Michigan’s forest lands – including extensive Federal and State holdings – continue to experience net growth every year. -

His research shows that inherited DNA differences are the major systematic force that make us who we are as individuals. The DNA Revolution, namely using DNA to predict our psychological problems and promise from birth, calls for a radical rethink about what makes us who we are, with sweeping—and no doubt controversial—implications for the way we think about parenting, education and the events that shape our lives.

INTRODUCTION The Framework Convention of the United Nations on Climate Change is an attempt to deal with the problems of the greenhouse effect, that is the increase of the global average temperature at the Earth surface, due to the growing concentration of some gases in the atmosphere, such as carbon dioxide from fossil fuels combustion. Its objective is to restrict the concentration of those greenhouse gases in the atmosphere to levels below those, which could cause possible climate change and undue interference with existing ecosystems. Except for the major oil producers, almost all countries, in Rio de Janeiro, signed the Convention in 1992. Besides the UN Convention, there exists since 1988, an intergovernmental group of experts – IPCC (The Intergovernmental Panel on Climate Change), in charge of evaluating scientific literature worldwide on the subject of global warming, and of producing a summary report of the findings. -
Adaptive Model Building Framework for Production Planning in the Primary Wood Industry
Article Adaptive Model Building Framework for Production Planning in the Primary Wood Industry Matthias Kaltenbrunner * , Maria Anna Huka and Manfred Gronalt Institute of Production and Logistics, Department of Economics and Social Sciences, BOKU–University of Natural Resources and Life Science, Feistmantelstrasse 4, 1180 Vienna, Austria; [email protected] (M.A.H.); [email protected] (M.G.) * Correspondence: [email protected] Received: 29 October 2020; Accepted: 23 November 2020; Published: 26 November 2020 Abstract: Production planning models for the primary wood industry have been proposed for several decades. However, the majority of the research to date is concentrated on individual cases. This paper presents an integrated adaptive modelling framework that combines the proposed approaches and identifies evolving planning situations. With this conceptual modelling approach, a wide range of planning issues can be addressed by using a solid model basis. A planning grid along the time and resource dimensions is developed and four illustrative and interdependent application cases are described. The respective mathematical programming models are also presented in the paper and the prerequisites for industrial implementation are shown. Keywords: production planning; sawmill; modelling framework; mathematical programming; integrated planning 1. Introduction In production planning, the quantities to be produced are planned taking into account capacities, processes, the availability of raw materials and demanded products. In the primary wood industry, logs are used as raw materials in sawmills and processed into many intermediate products for further processing. These value-adding processes are usually carried out at one location. Three different value-added stages—sawing, drying and planing—are performed by a sawmill. -
