Pine Tar & Wood Protection Asphalt & Roof Care
PINE TAR & WOOD PROTECTION ASPHALT & ROOF CARE PINE TAR NAture’s own wood PROTECTION Pine tar has been used in Scandinavia for hundreds of years to protect and preserve wooden buildings, boats, jetties and eve- ryday items. As well as protecting wooden structures against rot, natural tar is also mildly antiseptic. This characteristic means that pine tar is used in a number of different pharma- ceutical and veterinary products for treating skin complaints. It is therefore a common ingredient in skin ointments, soap and shampoo, etc. For a long time pine tar was one of Sweden’s most important export items. A protective oil – direct from the forest Pine tar is a viscous blackish-brown liquid consisting of vola- tile terpene oils, neutral oils, resin acids and fatty acids. It’s the combination of these substances that allows mediaeval wood- en buildings that have been regularly treated with pine tar to still stand today. The proportion of these constituents varies in different tar qualities, depending on the type of wood, its age and the part of the tree used. Historically, resin-rich pine stumps have always been considered to give the best pine tar, as resin contains substances that protect the living tree from rot, insect infestation and so on. Since it has become harder to get hold of stumps, tree trunks and branches are now used to a greater extent. Aromatic and easily soluble Pine tar is transparent in thin layers and has a natural aromatic scent. It’s pretty much fully soluble in alcohol and turpentine, as well as almost completely compatible with fatty oils. -

West Virginia's Forests
West Virginia’s Forests Growing West Virginia’s Future Prepared By Randall A. Childs Bureau of Business and Economic Research College of Business and Economics West Virginia University June 2005 This report was funded by a grant from the West Virginia Division of Forestry using funds received from the USDA Forest Service Economic Action Program. Executive Summary West Virginia, dominated by hardwood forests, is the third most heavily forested state in the nation. West Virginia’s forests are increasing in volume and maturing, with 70 percent of timberland in the largest diameter size class. The wood products industry has been an engine of growth during the last 25 years when other major goods-producing industries were declining in the state. West Virginia’s has the resources and is poised for even more growth in the future. The economic impact of the wood products industry in West Virginia exceeds $4 billion dollars annually. While this impact is large, it is not the only impact on the state from West Virginia’s forests. Other forest-based activities generate billions of dollars of additional impacts. These activities include wildlife-associated recreation (hunting, fishing, wildlife watching), forest-related recreation (hiking, biking, sightseeing, etc.), and the gathering and selling of specialty forest products (ginseng, Christmas trees, nurseries, mushrooms, nuts, berries, etc.). West Virginia’s forests also provide millions of dollars of benefits in improved air and water quality along with improved quality of life for West Virginia residents. There is no doubt that West Virginia’s forests are a critical link to West Virginia’s future. -

(DGEBA) Epoxy Resin with Maleated Depolymerised Natural Rubber
eXPRESS Polymer Letters Vol.2, No.4 (2008) 302–311 Available online at www.expresspolymlett.com DOI: 10.3144/expresspolymlett.2008.36 Modification of (DGEBA) epoxy resin with maleated depolymerised natural rubber K. Dinesh Kumar1,2, B. Kothandaraman1* 1Department of Rubber and Plastics Technology, MIT campus, Anna University, Chennai-6000 44, India 2Current address: Rubber Technology Centre, Indian Institute of Technology, Kharagpur-721302, India Received 30 December 2007; accepted in revised form 13 March 2008 Abstract. In this work, diglycidyl ether of bisphenol A (DEGBA) type epoxy resin has been modified with maleated depolymerised natural rubber (MDPR). MDPR was prepared by grafting maleic anhydride onto depolymerised natural rub- ber. MDPR has been characterized by Fourier transform infrared (FT-IR) spectroscopy and nuclear magnetic resonance spectroscopy. MDPR was blended with epoxy resin at three different ratios (97/3, 98/2 and 99/1), by keeping the epoxy resin component as the major phase and maleated depolymerised natural rubber component as the minor phase. The reac- tion between the two blend components took place between the acid/anhydride group in the MDPR and the epoxide group of the epoxy resin. The proposed reaction schemes were supported by the FT-IR spectrum of the uncured Epoxy/MDPR blends. The neat epoxy resin and Epoxy/MDPR blends were cured by methylene dianiline (DDM) at 100°C for three hours. Thermal, morphological and mechanical properties of the neat epoxy and the blends were investigated. Free volume stud- ies of the cured, neat epoxy and Epoxy/MDPR blends were correlated with the morphological and mechanical properties of the same systems using Positron Annihilation Lifetime Studies. -
New Insurance for Newbuildi

Team Göteborg I We will soon complement the products we have by adding an insurance that specifi cally targets the needs of shipowners with newbuildings on order. Our fi rst contact with owners has traditionally been when they have started to look for suppliers of H&M, P&I Cover for liabilities in respect and FD&D insurances. We do in some cases cover FD&D for newbuildings and of superintendents and for the crew whilst travelling to and from the shipyard just prior to delivery. We feel that owners need to start looking at their insurable interests long other shipowners’ personnel before delivery, as there are risks relating to the newbuilding that could affect attending at newbuildings owners adversely. Only a few owners currently do this. Our Newbuilding Risks Insurance is one product and it encompasses three areas: 1.

HOW THE INDUSTRY 4.0 COULD AFFECT THE SHIPBUILDING WORLD Rodrigo Pérez Fernández, [email protected], correspondence author SENER, Madrid/Spain. C/ Severo Ochoa, 4 - 28760 Tres Cantos - Madrid (Spain) Abstract The marine structures are developed with Computer Aided Design (CAD) platforms, but every day we are looking for integrated development of the product involving all its Life Cycle. CAD system integrated with Product Lifecycle Management (PLM) and from the PLM we can conceive all the design but also control the production and include the use of the vessel. The PLM can contain information of all systems of the vessel and also all its components. If the components are designed for the Internet of Ships (IoS) it will have technology that allows to share their situation, diagnosis, functionality with the PLM system which distributes the initial design. The PLM system can use this information for knowing whether they are working properly or if we can improve its performance. It is also possible to identify whether it is necessary to make maintenance of the object or if it is necessary to replace it because its life ends or because it's working wrongly. It will be possible to determine and evaluate its performance comparing to other similar components or comparing to it different operating periods. It will also be possible to know how their performance affects the functioning of the whole product, i.e., the vessel. Furthermore, if the connection of the objects is realized with its PLM, it would be possible to record their history status, make change tracking, and know what is its function or its performance after realizing programmed maintenance. -

Education Roadmap for Mining Professionals
Education Roadmap for Mining Professionals December 2002 Mining Industry of the Future Mining Industry of the Future Education Roadmap for Mining Professionals FOREWORD In June 1998, the Chairman of the National Mining Association and the Secretary of Energy entered into a compact to pursue a collaborative technology research partnership, the Mining Industry of the Future. Following the compact signing, the mining industry developed The Future Begins with Mining: A Vision of the Mining Industry of the Future. That document, completed in September 1998, describes a positive and productive vision of the U.S. mining industry in the year 2020. It also establishes long-term goals for the industry. One of those goals is: "Improved Communication and Education: Attract the best and the brightest by making careers in the mining industry attractive and promising. Educate the public about the successes in the mining industry of the 21st century and remind them that everything begins with mining." Using the Vision as guidance, the Mining Industry of the Future is developing roadmaps to guide it in achieving industry’s goals. This document represents the roadmap for education in the U.S. mining industry. It was developed based on the results of an Education Roadmap Workshop sponsored by the National Mining Association in conjunction with the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, Office of Industrial Technologies. The Workshop was held February 23, 2002 in Phoenix, Arizona. Participants at the workshop included individuals from universities, the mining industry, government agencies, and research laboratories.
