Timber spatial trusses using laminated veneer lumber

open access: yesJournal of Building Engineering
A simple and innovative preloaded dowel-nut connection is proposed for high-performance spatial structures made of Laminated Veneer Lumber (LVL). To demonstrate the connection feasibility, three prototypes were built with spruce LVL trusses connected at steel spheres: non-preloaded connections were used in prototype 1; conversely, a tightening torque ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

open access: yesThe Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Laminated veneer lumber (LVL) manufacturing using three hybrid poplar clones

open access: yesTurkish Journal of Agriculture and Forestry, 2012
Laminated veneer lumbers (LVLs) were manufactured from veneers of 3 rotary peeled fast growing hybrid poplar clones, I-214 (Populus xeuramericana), I-77/51 (Populus deltoides), and S.307-26 (Populus deltoides), with a phenol formaldehyde (PF) adhesive. Two Populus deltoides clones that are grown in Turkey were used for the first time in LVL production.

Marine silicon for biomedical sustainability

open access: yesBMEMat, EarlyView.
Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

Some technological properties of laminated veneer lumber produced with fast-growing Poplar and Eucalyptus

open access: yesMaderas: Ciencia y Tecnología, 2016
Fast-growing tree species are important due to their short growth time before they are harvested. Both the Poplar and Eucalyptus species are fast-growing trees.

Overcoming intranasal delivery barriers with ultrastable polyzwitterionic siRNA nanocages for enhanced glioblastoma therapy

open access: yesBMEMat, EarlyView.
A ROS‐responsive, zwitterionic nanocage enables stable, intranasal siRNA delivery to glioblastoma, promoting deep tumor penetration via non‐degradative pathways and trigeminal nerve transport. This platform achieves durable gene silencing and tumor suppression, offering a non‐invasive, storage‐stable strategy for treating glioma and other neurological ...

Performance of Laminated Veneer Lumber Panels from Fast-Growing Species with Different Layering Arrangements

open access: yesBioResources
This study investigated the effect of various layer arrangements and their impact on the properties of laminated veneer lumber (LVL). Seven different layer arrangements (CCCCCCC, DDDDDDD, PPPPPPP, CDDDDDC, CPPPPPC, CDDCDDC, CPPCPPC, CDCDCDC, CPCPCPC ...

Experimental and modelling buckling of wood-based columns under repeated loading

open access: yesEPJ Web of Conferences, 2010
Collapse of timber constructions can appear under the effect of load that exceeds the resistance of a carrying element or under the effect of a geometrical instability like buckling.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.
