Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Earthquakes and robustness [PDF]

open access: yes, 2011
This guideline was prepared within the COST Action E55 "Modelling of the performance of timber structures" WG3 "Robustness of Structures". The main objective of the Action is to provide the basic framework and knowledge required for the efficient ans ...

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Automated Feature Extraction and Classification of Submerged Cultural Heritage Assets in the Puck Lagoon via Multisensor Remote Sensing

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This study presents a strong framework for the detection and classification of Submerged Cultural Heritage Assets (SCHA) in shallow marine environments using the integration of multibeam echosounder and airborne LiDAR bathymetry with object‐based image analysis and fuzzy logic–based classification.

Component method extension to steel beam‐to‐beam and beam‐to‐column knee joints under bending and axial forces

open access: yesJournal of Civil Engineering and Management, 2005
This paper presents an analysis of semi‐rigid beam‐to‐beam end‐plate bolted and beam‐to‐column end‐plate bolted knee joints that are subjected to bending and tension or compression axial force.

Weld size and resistance in rectangular hollow section T-joints

open access: yesHeliyon, 2023
When chord face failure occurs, one of the factors, which influence the resistance of the square hollow sections joint is the brace-to-chord width ratio of the joint. This includes the size of the weld connecting the two members.

Comparison of behaviour of laterally loaded round and squared timber bolted joints [PDF]

open access: yes, 2016
In the current European standards for design of timber structures, the issue of timber-to-timber joint type is addressed only to squared timber, which makes the pinpointing of the round timber bolted joints load carrying capacity near-unfeasible due to ...

Exploring the potential of ucuúba (Virola surinamensis) seed fat

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Ucuúba (Virola surinamensis) fat is an important income source for Amazonian communities. Local businesses typically process whole seeds for fat extraction; however, seed structural integrity may influence extraction efficiency and fat quality.
