Abstract Araucarioxylon Kraus is a widely known fossil‐genus generally applied to woods similar that of the extant Arau‐ cariaceae. However, since 1905, several researchers have pointed out this name an illegitimate junior nomenclatural synonym. At least four generic names are in current use for fossil wood type: Agathoxylon Hartig, , Dadoxylon Endl. and Dammaroxylon J. Schultze‐Motel. This problem inconsistent application compounded by fact type represent wide range plants including basal...
Tensile strength perpendicular to the plane of board (also known as Internal Bond—IB), determined in accordance with standard EN 319, is one most critical properties particleboard quality control. Given need for efficient, rapid methods assess IB industrial contexts, artificial neural networks (ANN) have been used a predictive modelling tool. However, main limitations these techniques absence estimates associated uncertainty their predictions. The present study addresses this shortfall by...
The physical properties (specific gravity, moisture content, thickness swelling and water absorption) mechanical (internal bond strength, bending strength modulus of elasticity) were determined on 93 Spanish-manufactured standard particleboards different thicknesses selected randomly at the end production process. testing methods corresponding European standards (EN) used, except in case absorption tests, for which Spanish UNE was used. values obtained entered into an artificial neural...
Abstract The bonding quality test is one of the most important all tests performed on plywood, because it determines suitability boards for use in type exposure they are intended for. Because this involves aging pretreatment, results not available <24–97 h after manufacture, depending board, and therefore any error manufacturing process detected until 1–4 days later. To solve time problem, an artificial neural network was developed as a predictive method to determine board through other...
Hardwoods are complex heterogeneous and orthotropic structures that have evolved to the present day, adapting successive climate episodes prosper on Earth. Attributing a specific functionality individual hardwood elements is difficult because of their interconnection in this three-dimensional network. However, tree physiology research helping enhance knowledge field. This work short review possible functionalities elements, some cases supported by experimentation others comparative anatomy....
The main objective of this study was to identify differential anatomical features between Ulmus pumila L. and minor Mill. clones resistant Dutch elm disease U. susceptible disease, with a focus on the intervascular pits medullary rays. Resistant elms showed lower mean values than for pit membrane diameter, aperture area, abundance per vessel-wall ray width, tangential area. A principal component analysis parameters measured revealed slight differentiation species but clearly grouped...
Following the traditional methods of preparation and description wood at microscopy level, 352 descriptions woods conifers were made. For characterisation each a multiple entry key was prepared, with total 81 features divided into four groups: tracheids 29 features, axial parenchyma 8, rays 37 resin canals 7.
Abstract The conifer forests of the Mediterranean Basin have been subjected to overuse by humans since ancient times. Some species survived in inaccessible refuges but ranges other greatly reduced effects clearance for agriculture, livestock raising, illegal felling and, some cases, fire. firs are no exception and now exist only as relict species. Abies pinsapo is an example, with surviving three enclaves southern Spain two northern Morocco. Until mid 20th century A. were subject major...
Abstract The hygroscopicity and thermodynamic properties of juvenile Pinus sylvestris L. wood taken from the submerged piles a bridge built in 1903 over Jiloca River, Spain, were compared with corresponding values same species recently cut trees. 35°C 50°C isotherms plotted subsequently fitted using Guggenheim-Anderson-Boer-Dent method, isosteric heat sorption was obtained through integration method Clausius-Clapeyron equation. by means hysteresis coefficients. Infrared spectra recorded to...
Neural networks are complex mathematical structures inspired on biological neural networks, capable of learning from examples (training group) and extrapolating knowledge to an unknown sample (testing group). The similarity wood structure in many species, particularly the case conifers, means that they cannot be differentiated using traditional methods. use can effective tool for identifying similar species with a high percentage accuracy. This predictive method was used differentiate...
