Mean values of dynamic (dMOE) and static modulus of elasticity (sMOE) of B. augustifolia wood obtained were 6.908 ± 0.7525 GPa and 6.9148 ± 0.5870 GPa, respectively. Analysis done showed no significant difference between the values from the two methods while regression model was significant with 0.65 coefficient of determination. Strong correlation of 0.81 was observed between the dMOE and sMOE. Meanwhile, wood density had a correlation of 0.73 and 0.50 with dMOE and sMOE respectively.

Students taking a course in wood protection used a VR device to explore the distribution of silica in satinay and copper in pine. Students were surveyed to assess their views on the system as a learning tool. The results showed that students were very positive about the VR system, and they frequently commented that the system was better than traditional methods at aiding understanding of wood structure/protection.

The effect of inorganic filler on elastic and strength properties, dimensional stability and formaldehyde emissions was investigated. The results demonstrated that the addition of filler in amounts up to 10 wt-% in surface layers does not significantly affect mechanical properties. Further increase in filler addition above 10 wt-% resulted in a nearly linear decrease in bending properties and increase in water uptake, however did not significantly affect dimensional stability and formaldehyde emissions.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2020-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1735753","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45803563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Significant positive correlation coefficients were found between the stress-wave velocity of standing trees and MOE (r = 0.776) and MOR (r = 0.702) of this lumber. The dynamic Young’s modulus of the logs also correlated significantly with MOE (r = 0.745) and MOR (r = 0.584) values.

For each cultivar, two trees were harvested per station; crosscut into bolts then peeled 1.4 mm thick for one tree and 3 mm thick for the other one: in total, 80 trees were sampled. The veneers were used to make 160 boards using 2 adhesives: polyvinyl acetate (PVAc) and melamine-urea-formaldehyde (MUF). These boards were then cut into standardized samples for non-destructive and destructive mechanical tests. The properties of plywood were characterized by measuring their density, modulus of elasticity and modulus of rupture. The results showed that poplar plywood properties could be influenced by adhesive and veneer thickness. The cultivar and soil effects were never relevant. A tight correlation was found between destructive and non-destructive modulus of elasticity tests.","PeriodicalId":14414,"journal":{"name":"International Wood Products Journal","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2020-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/20426445.2020.1735729","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45964993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most effective use is to grow ornamental plants. When betel trunks are used for planting the irrigation nutrients will not flow out quickly. When the root of the plant is gradually extended, the humus fibre of the trunk is closely combined with the root and forms an excellent planting environment.

Analysis indicated that the cross-linking species in these hardeners was 2,5-dihydroxymethyl furan linked to carbohydrate chains. The extracts obtained in comparison to paraformaldehyde cured adhesives in equal proportions (10%) show that the ‘biohardener’ had properties for adhesive and eco-friendly applications.
