Aim of study: This study aimed to improve some physical, mechanical properties, and fire resistance wood-plastic composites (WPCs) with short glass fiber reinforcement (SGFR). Materials Methods: The WPCs were reinforced different ratios (SGF). effect on the water absorption (WA), thickness swelling (TS) as physical flexural strength, modulus elasticity, tensile strength properties determined. p...

Urea-formaldehyde is one of the commonly used resin types in particleboard industry. In this study, effect nanofibrillated cellulose (NFC) and titanium dioxide (TiO2) addition formulation urea formaldehyde on physical, mechanical, morphological properties samples was investigated. The NFC (0.5% 1%) TiO2 (0.5%, 1%, 2%) were added to 10% adhesive formulation. Two different pressure times, 4 8 min...

One of the most persistent problems with mechanically densified wood is its inherent dimensional instability. The effects of heat post-treatment on the changes in spring-back (SB), compression ratio recovery (CRR), thickness swelling (TS), and water absorption (WA) of newly-tested Uludağ fir (Abies bornmuelleriana Mattf.) and black poplar (Populus nigra L.) wood samples that had been thermo-mec...

Most of the irrigated agricultural regions in Europe are supplied by surface irrigation networks managed by local water authorities (WAs). Under such conditions, WAs are not able to fully monitor water usage and farmers have an information advantage vis-a-vis the WA. This results in the water authority suffering ‘pricing failure’ if it decides to apply an incentive pricing strategy (tariffs pro...

The present research investigates the mechanical and physical properties of recycled aggregate concrete (RAC) modified with micro-silica (MS) tire steel fiber (RTSF). Natural coarse aggregates (NCA) were completely replaced by (RCA) to prepare RAC. High-strength RAC mixes prepared replacing 5% 10% Portland cement MS. With each level MS, RTSF was incorporated as 0%, 0.5%, 1 2% volume fraction. I...

partial replacement of formaldehyde with furfural in the urea-formaldehyde resin on the formaldehydeemission, physical and mechanical properties of particleboard was investigated. the modulus ofrupture (mor), modulus of elasticity (moe), internal bond (ib), water absorption (wa), thicknessswelling (ts) and formaldehyde emission (fe) of poplar particleboards made with the modifiedresins were mea...

BACKGROUND As Western Australia's (WA) government enacts shark bite mitigation, the personal risk of shark bite in WA has not been studied. AIMS Model the risk of large (>3m) white shark bite (Carcharodon carcharias, LWS) in southwest WA. METHOD An observational study inclusive of 1 January 1974 to 31 December 2013 was conducted. Analysis of prey abundance, location, water temperature, and ...

The aim of this study was to analyze the long-term color stability of eight self-adhesive composite resin cements (SACRCs) after storage in diverse media for up to one year. 480 discs (diameter: 12 mm/thickness: 1.0 ± 0.05 mm) were fabricated (n = 60/SACRC): (1) BeautyCem (BEA); (2) Bifix SE (BIF); (3) Clearfil SA Cement Automix (CLE); (4) RelyX Unicem 2 Automix (RXU); (5) SeT (SET); (6) SmartC...
