Singleand three-layer mixed hardwood oriented strandboard (OSB) with various wood fines contents and panel densities were manufactured using phenol-formaldehyde (PF) resin as binder. The effects of fines level and density on the panel properties were studied. Mathematical models based on lamination theories were used to predict properties of three-layer panels, including effective modulus (EM),...

This article argues that it is doubtful that the fivefold increase in maximum fines under New Zealand’s Health and Safety in Employment Amendment Act 2002 will be successful in providing suitable precautionary incentives. Expected penalties remain at relatively low levels, with the continued use of capped fines along with substantial margins for deterrence of the most serious cases. On average,...

Instruments for optical fiber measurements, such as the Fiber Quality Analyzer (FQA), are widely used to measure various properties of pulp samples. For the evaluation of market pulps, the pulp properties of interest are fiber length, coarseness, and fines content. Fiber length and coarseness are often used to determine which pulps are suitable for producing particular products. The objectives ...

A mobile, low-field nuclear magnetic resonance (NMR) sensor for onboard, inline detection of catalytic fines in fuel oil in the shipping industry is presented as an alternative to onshore laboratory measurements. Catalytic fines (called cat fines) are aluminosilicate zeolite catalysts utilized in the oil cracking process at refineries. When present in fuel oil, cat fines cause abrasive wear of ...

The scope of this study is to enhance the industry understanding of the sustainable utilization of quarry dust, and to identify any gaps in current knowledge. The term sustainable utilization implies the use of quarry dust to their full potential to meet the needs of the present, while at the same time conserving natural resources and finding ways to minimize the environmental impacts associate...
