Glued-Laminated Timber Bridges
Glued-Laminated Timber Bridges Glulam design s are the most commonly used modern timber bridge designs The first glulam bridges were built in the mid-1940's. Since that time, they have become the most common type of timber bridge in both single and multi-span con figurations. Glulam beam bridges are completely prefabricated in modular compo nents and are treat ed with preservatives Wea llng surlac e ,r tsee Chapter 11) after fabrication.

Glulam Design Properties and Layup Combinations
GLULAM DESIGN PROPERTIES AND LAYUP COMBINATIONS ENGINEERED WOOD SYSTEMS WOOD The Miracle Material™ Wood is the right choice for a host of construction applications. It is the earth’s natural, energy efficient and renewable building material. Engineered wood is a better use of wood. The miracle in today’s wood products is that they make more efficient use of the wood fiber resource to make stronger plywood, oriented strand board, I-joists, glued laminated timbers, and laminated veneer lumber. That’s good for the environment, and good for designers seeking strong, efficient, and striking building design. A few facts about wood. I We’re not running out of trees. One-third of the United States land base – 731 million acres – is covered by forests. About two-thirds of that 731 million acres is suitable for repeated planting and harvesting of timber. But only about half of the land suitable for growing timber is open to logging. Most of that harvestable acreage also is open to other uses, such as camping, hiking, and hunting. Forests fully cover one-half of Canada’s land mass. Of this forestland, nearly half is considered productive, or capable of producing timber on a sustained yield basis. Canada has the highest per capita accumulation of protected natural areas in the world – areas including national and provincial parks. I We’re growing more wood every day. American landowners plant more than two billion trees every year. In addition, millions of trees seed naturally. The forest products industry, which comprises about 15 percent of forestland ownership, is responsible for 41 percent of replanted forest acreage. -

First edition: 2006 Author: Tinde van Andel Illustrator: Bertha Valois V. Design: Eva Kok Translation: Ninette de Zylva (editing) Printed by: Digigrafi, Wageningen, the Netherlands ISBN Agromisa: 90-8573-027-9 ISBN CTA: 92-9081-327-X Foreword Non-timber forest products (NTFPs) are wild plant and animal pro- ducts harvested from forests, such as wild fruits, vegetables, nuts, edi- ble roots, honey, palm leaves, medicinal plants, poisons and bush meat. Millions of people – especially those living in rural areas in de- veloping countries – collect these products daily, and many regard selling them as a means of earning a living. This Agrodok presents an overview of the major commercial wild plant products from Africa, the Caribbean and the Pacific. It explains their significance in traditional health care, social and ritual values, and forest conservation. It is designed to serve as a useful source of basic information for local forest dependent communities, especially those who harvest, process and market these products. We also hope that this Agrodok will help arouse the awareness of the potential of NTFPs among development organisations, local NGOs, government officials at local and regional level, and extension workers assisting local communities. Case studies from Cameroon, Ethiopia, Central and South Africa, the Pacific, Colombia and Suriname have been used to help illustrate the various important aspects of commercial NTFP harvesting. -
Review of Smoke Taint in Wine: Smokederived Volatile Phenols And
Krstic et al. Review of smoke taint in wine 537 Review of smoke taint in wine: smoke-derived volatile phenols and their glycosidic metabolites in grapes and vines as biomarkers for smoke exposure and their role in the sensory perception of smoke taint M.P. KRSTIC1, D.L. JOHNSON2 and M.J. HERDERICH2 1 The Australian Wine Research Institute,Victorian Node, Mooroolbark, Vic. 3138, Australia; 2 The Australian Wine Research Institute, Urrbrae, SA 5064, Australia Corresponding author: Dr Mark Krstic, email [email protected] Abstract In recent years, the exposure of vineyards and grapes to smoke from bushfires and controlled burn events has in some instances resulted in wines described as smoke tainted. Such wines are characterised by undesirable sensory characters described as smoky, burnt, ash, smoky bacon, medicinal and ashtray. This review summarises the knowledge about the composition of smoke from forest and grass fires, describes relationships between smoke exposure of vineyards and smoke taint in wine, and outlines strategies for managing and reducing the risk to producing smoke-affected wines. The sensitivity of grapes and vines at different phenological stages to the uptake of contaminants from smoke, especially smoke-derived volatile phenols, is outlined, and the pathways for entry and metabolic transformation of volatile phenols are discussed. The potential for translocation of phenolic contaminants within the grapevine and the differences in uptake of smoke contaminants of different grape cultivars are also discussed, along with preliminary work on dose/response relationships regarding concentration and duration of exposure and subsequent expression of smoke taint in wine. The chemical basis of smoke taint in wine is described, and the relationship between volatile phenols from combustion of wood/lignin and their glycosides, and sensory panel ratings of smoke attributes in affected wines is discussed. -
(Acacia Mangium) and Sengon (Falcataria Moluccana) Smoked Wood1
J. Korean Wood Sci. Technol. 2020, 48(1): 1~11 pISSN: 1017-0715 eISSN: 2233-7180 https://doi.org/10.5658/WOOD.2020.48.1.1 Original Article Color Change and Resistance to Subterranean Termite Attack of Mangium (Acacia mangium) and Sengon (Falcataria moluccana) Smoked Wood1 Yusuf Sudo HADI 2,†⋅Muh Yusram MASSIJAYA2⋅Imam Busyra ABDILLAH2⋅ Gustan PARI3⋅Wa Ode Muliastuty ARSYAD3 ABSTRACT1) Indonesian log production is dominated by young trees harvested from plantation forests. The timber contains of sapwood and juvenile wood, which are not resistant to termite attack. Smoking treatment can enhance wood resistance to termite attack, but it also changes the color. Specimens of mangium (Acacia mangium) and sengon (Falcataria moluccana) wood were exposed for 1, 2, and 3 weeks to smoke produced from the pyrolysis of salam (Syzygium polyanthum) wood. The color change of the wood was measured using the CIELab method. In addition, wood specimens were exposed to subterranean termites (Coptotermes curvignathus Holmgren) under laboratory conditions. Untreated and imidacloprid-preserved wood samples were also prepared for comparison purposes. The results showed that the color of smoked wood differed from that of untreated wood, and the color change for sengon was greater than for mangium. In addition, the 1-week smoking period changed the wood color less than the 2- and 3-week periods, which did not differ. Imidacloprid-preserved wood had distinctive color changes compared to untreated wood. Untreated mangium wood had moderate resistance to subterranean termite attack (resistance class III), while sengon had very poor resistance (resistance class V). Salam wood smoke enhanced wood resistance to termite attack, and smoke treatment of 1 week for mangium and 2 weeks for sengon resulted in the wood becoming very resistant (resistance class I). -
Smoke Flavourings
SMOKE FLAVOURINGS Prepared at the 57th JECFA (2001) and published in FNP 52 Add. 9 (2001), superseding tentative specifications prepared at the 55th JECFA (2000) and published in FNP 52 Add. 8 (2000). An ADI of “Provisional acceptance” was established at the 31st JECFA (1987). SYNONYMS Wood smoke flavour, Smoke condensate DEFINITION Complex mixtures of components of smoke obtained by subjecting untreated hardwoods to (a) pyrolysis in a limited and controlled amount of air, (b) dry distillation between 200o and 800o, or (c) superheated steam between 300o and 500o. Source materials must not contain detectable amounts of pesticides, wood preservatives, or other extraneous matter that may result in hazardous constituents in the wood smoke. The major flavouring principles of Smoke Flavourings are carboxylic acids, compounds with carbonyl groups and phenolic compounds. During manufacture, wood smoke is subjected to an aqueous extraction system or to distillation, condensation, and separation for collection of the aqueous phase, which serves to remove hazardous constituents, such as polycyclic aromatic hydrocarbons. The aqueous smoke fraction containing water-soluble constituents may be diluted with water or be extracted with an edible vegetable oil to produce a smoke flavouring with higher levels of non- polar constituents that may be further extracted using food-grade substances, such as propylene glycol or aqueous solutions of polysorbates. Commercial products may also contain additives such as emulsifiers, antifoaming agents, and gums. Smoke flavourings may also be prepared in dry form with the addition of carriers, such as yeasts, flours, salt, phosphates, carbohydrates, and anti-caking agents. These specifications apply only to the water-soluble distillates of condensed wood smoke, their aqueous/vegetable oil or polysorbate extracts and concentrates of these. -

LITERATURE AND REFERENCES Project co-funded by the European Union (ERDF, IPA funds) 1. INTRODUCTION Riparian forests are habitats serving multiple functions for flora, fauna and humans. In the past century, around 90% of the original Danube wetlands have been lost due to human activities. Today, most of the last remaining large-scale floodplain forest complexes are protected by the Danube Protected Areas, famous for their richness in biodiversity. Riparian forests are of great ecological importance, playing an important role in both nature and human populations.
