50 – Román-Jordán, E., García Esteban, L., de Palacios, P., García Fernández, F. Wood anatomy of Cupressus and its relation to geographical distribution. IAWA Journal. 37(1): 48-68.

The wood anatomy of 14 species of Cupressus was studied to determine whether there is a pattern of wood anatomical diversity between the species from the North and Central American (western) region and the Eurasian (eastern) region. Xanthocyparis vietnamensis and Chamaecyparis nootkatensis (syn. Xanthocyparis nootkatensis) were also studied to compare […]

Comparison of modelling using regression techniques and an artificial neural network for obtaining the static modulus of elasticity of Pinus radiata D. Don. timber by ultrasound. Composites Part B: Engineering. 96:112-118.

The traditional regression method was compared with an artificial neural network for obtaining the static modulus of elasticity (MOEstatic) of Pinus radiata timber using the dynamic modulus of elasticity determined by ultrasound in the first case and ultrasonic wave propagation velocity in the second case […]

47 – García Esteban, L., Simón, C., García Fernández, F., de Palacios, P., Martín-Sampedro, R., Eugenio, M.E., Hosseinpourpia, R. Juvenile and mature wood of Abies pinsapo Boissier: sorption and thermodynamic properties. Wood Science and Technology. 49(4): 725-738.

For industrial processes, it is important to study the hygroscopicity and thermodynamic properties of juvenile and mature wood. Samples of Abies pinsapo Boiss. collected in the natural areas of the species in Spain were used to study these properties in both types of wood. The equilibrium moisture contents were obtained, and the 15, 35 and 50 ºC isotherms were plotted following […]

46 – Simón, C., García Esteban, L., de Palacios, P., García Fernández, F., Martín-Sampedro, R., Eugenio, M.E. Thermodynamic analysis of water vapour sorption behaviour of juvenile and mature wood of Abies alba Mill. Journal of Material Science. 50(22):7282-7292.

The hygroscopicity and thermodynamic properties of juvenile and mature wood of Abies alba Mill. were studied through the 15, 35 and 50 °C sorption isotherms. The Guggenheim, Anderson and de Boer-Dent model was used to fit the isotherms. The thermodynamic parameters were obtained from the sorption isotherms by applying the integration method of the Clausius–Clapeyron equation […]

 For the first time, the wood anatomy of Tetraclinis articulata (Vahl) Masters has been studied using representative samples from its natural distribution area in Spain, in Sierra de Cartagena (Region of Murcia). Mature wood was collected from five individuals representative of the forest stand and their anatomy was compared with other genera of the Cupressaceae […]

Fossil woods of the genus Protocupressinoxylon Eckhold are reported from the Lower Cretaceous (upper Aptian e lower Albian) of Casal do Estortiga, near Santa Catarina da Serra, Lusitanian Basin, western Portugal. The three silicified specimens show up to 7-mm-thick-walled, rounded to polygonal tracheids; homogeneous rays, separated by 2 e 8 cell rows […]
