Bacterial chondronecrosis with osteomyelitis (BCO) is the most common cause of lameness in commercial broilers. Bacteria entering the blood via translocation from the respiratory system or gastrointestinal tract spread hematogenously to the proximal epiphyseal-physeal cartilage of rapidly growing femora and tibiae, causing BCO. We tested the hypothesis that rearing broilers on wire flooring sho...

The anti-skid resistance of six coatings (Alfa, Beta, Gamma, Lambda, Mu and Theta) designed for outdoor wood flooring were tested in chestnut (Castanea sativa Mill.) and pine (Pinus pinaster Ait.) using a Portable Skid Resistance Tester according to standard ENV 12633. Film thickness, coating retention level, and presence of mineral particles were determined for each coating. Furthermore, the l...

Ultraviolet light emitting diodes (UV-LEDs) have attracted great interest in recent years. They can be used to polymerize coatings, such as those used for prefinished wood flooring. In this project, two lamps were compared for their suitability to be used on a wood flooring finishing line: a UV-microwave and a UV-LED lamp. Low heat emission was found for the UV-LED lamp compared to the UV-micro...

In situ imaging nanoindentation was used to characterize the mechanical properties of pure paint films on eight types of plywood-based flooring with different wear resistance. Correlation between the mechanical properties of paint films and the wear resistance of wood-based floorings was investigated. The average modulus of elasticity (MOE) and hardness of the paint film tested were 3.33–5.77 a...

Recent recommendations for wood dust sampling include sampling according to the inhalable convention of International Organization for Standardization (ISO) 7708 (1995) Air quality--particle size fraction definitions for health-related sampling. However, a specific sampling device is not mandated, and while several samplers have laboratory performance approaching theoretical for an 'inhalable' ...

Parquet flooring is one of the most common types flooring, surface which can be covered with various coatings. To avoid possible damage to parquet during use, it necessary test surfaces before installation according non-standard and standard protocols. The present study provides an overview interactions between properties selected waterborne coatings (solids content, hardness, resistance cracki...

This chapter describes the development of material-specific estimates of changes in forest carbon storage in EPA's Waste Reduction Model (WARM). It summarizes the approach used to estimate changes in forest carbon storage in managed forests resulting from source reduction and recycling of wood and paper products. Forests absorb (i.e., sequester) atmospheric carbon dioxide (CO 2) and store it in...
