The mass timber industry offers a compelling pathway for low-carbon structural systems in buildings, replacing carbon-intensive materials like concrete and steel with sustainably forested wood. However, conventional connections construction are largely made of metallic materials, such as screws, nails, plates. In contrast, joinery, or geometrically interlocking all-timber connections, is global...

Fatigue of a composite girder according to Eurocode 4 is carried out on the decisive shear connector. It not taken into account that an internally highly statically indeterminate system in which failure dowel does necessarily lead girder. This applies particular dowels are characterised by crack propagation phase with high residual load-bearing capacity damaged dowel. In own small part and test...

In Portland cement concrete (PCC) pavements, tie bars are commonly used at longitudinal construction joints (LCJs) to prevent the lanes from separating. Meanwhile, increase in multiple due greater traffic volumes has raised concerns about potential cracking; this led use of dowel instead LCJs. However, there is a paucity studies focused on comparison between behaviors pavement based restrained ...

STATEMENT OF PROBLEM The in vitro effectiveness of a uniform circumferential ferrule has been established in the literature; however, the effect of a nonuniform circumferential ferrule height on fracture resistance is unknown. PURPOSE This in vitro study investigated the resistance to static loading of endodontically treated teeth with uniform and nonuniform ferrule configurations. MATERIAL...

Under visual guidance, subjects reached for and manipulated an object that varied in weight and surface texture (slipperiness). The manipulatory action was either grasping, lifting, or posting in a slot. The task was constrained or unconstrained with respect to speed, grasp pattern, and contact force. Initiation time (pre-reach), movement time (reach), and post-contact errors were measured, to ...

Understanding the dispersion processes within marshes is important to assess their filtering abilities and their ecological limits. A laboratory experiment was designed to study the influence of marsh vegetation on longitudinal dispersion. The flow through vegetation was modeled by a recirculating current going through an array of wooden dowels in a 24 m long flume. The longitudinal dispersion ...

STUDY DESIGN  Retrospective case series. OBJECTIVE  To assess fusion rates in patients with sacroiliac joint (SIJ) pain following a minimally invasive technique using fibular dowel allograft. METHODS  Thirty-seven consecutive patients (mean age: 42.5 years [range, 23-63 years]) with SIJ pain treated with 38 minimally invasive elective SIJ arthrodeses were retrospectively reviewed using char...

Substrate vibrations are important in social and ecological interactions for many insects and other arthropods. Localization cues include time and amplitude differences among an array of vibration detectors. However, for small species these cues are greatly reduced, and localization mechanisms remain unclear. Here we describe a method of simulating the vibrational environment that facilitates i...
