Effect of the washers on the bearing resistance of the bolted connections
IOP Conference Series: Materials Science and EngineeringAbstract Bolted connections are the most common method of joining thin-walled galvanized sheets on site. Small diameter bolts (M8, M10 or M12) and the corresponding nuts are used for this purpose. Washers should be provided both under the heads of the bolts and the nuts in case of a single shear connection with one row of bolts ...

Theoretical Evaluation of Moment Resistance for Bolted Timber Connections [PDF]
MATEC Web of Conferences, 2019 Timber construction is nowadays becoming more and more favorable due to multiple advantages. In this paper, the connection type and material of timber building were first highlighted. Then, the bolted joints with slotted-in steel plates were systematically tested and analyzed.

Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants
Advanced Science, EarlyView.This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

Advanced Science, EarlyView.The interfacial stability and activity of Ni‐Fe‐based AEMWE anodes can be directly enhanced by operando voltage‐cycling in a FeOOH‐containing electrolyte. This process simultaneously induces Ni oxidation and Fe incorporation, forming an integrated, porous (Fe, Ni)OOH layer with high conductivity and durability.

Advanced Science, EarlyView.A flexible PDMS‐LATP polymer‐ceramic membrane creates lithium‐ion “superhighways” for rapid and selective extraction from complex brines. The amorphous PDMS matrix suppresses nonselective leakage and stabilizes the ceramic network, while LATP provides preferential Li+ conduction.

Behaviour and design resistance of long bolts in tension
Journal of Constructional Steel ResearchLong bolts, also known as bi-directional bolts, have multiple applications in structural engineering, particularly as an instrumental part of the adaptability and reusability of steel members. Despite that, the long bolt design is not properly covered by current standards.
