Effects of Collars on Scour Reduction at Bridge Abutments [PDF]

open access: yes, 2010
Bridge failures are generally resulted from scour of the bed material around bridge piers and abutments during floods. In this study, scour phenomenon around bridge abutments and collars, located at abutments as scour countermeasures, were experimentally

Identification of Dynamic Characteristics of Bridge Crossing Sungai Simpang Kiri Using Free Vibration Analysis

open access: yesMATEC Web of Conferences, 2016
This paper presents a free vibration analysis (FVA) of a reinforced concrete bridge crossing Sungai Simpang Kiri, located at Batu Pahat. The bridge consists of three simple spans with a total length of 70meter (20 m + 30 m + 20 m).

Oral Motion‐Powered Smart Dental Implant Abutment for In Situ Antibacterial and Cell Adhesion Through Piezoelectric Effect

open access: yesAdvanced Science, EarlyView.
We proposed a method based on the piezoelectric effect and fabricated an implant abutment on the basis of piezoelectric ceramic. Under physiological occlusal pressure, the oral motion‐powered smart dental implant abutments interacted with water and oxygen, promoting the formation of reactive oxygen species and achieving a synergistic and highly ...

COMPUTATIONAL SIMULATION OF SEDIMENT MOTION STABILITY PROCESS ON BRIDGE ABUTMENT DUE TO CRIB PLACEMENT (CASE STUDY: HARAPAN RIVER, JAYAPURA REGENCY)

open access: yesRudarsko-geološko-naftni Zbornik
Erosion occurs when the flow of velocity in a channel exceeds the threshold velocity that causes the bed material to move. This phenomenon is observed in the Harapan River, resulting in significant impacts, such as riverbed lowering and narrowing due to ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus

open access: yesThe Anatomical Record, EarlyView.
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Effect of surface treatments on the retention of implant-supported cement-retained bridge with short abutments: An in vitro comparative evaluation

open access: yesThe Journal of Indian Prosthodontic Society, 2018
Statement of Problem: In clinical situations, short implant abutments create lack of retention with overlying cemented prosthesis. Aims: The aim of this study is to evaluate the impact of different surface treatments on the retention of implant-supported

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Heat transfer model verification for thermal monitoring system of integral bridges

open access: yesActa Polytechnica CTU Proceedings, 2022
Thermal actions considered on abutments of integral bridges by the European standard (Eurocode 1) might be in variety of certain situations underestimated. Based on this assumption, thermal monitoring system has been designed and installed into structure

Knotless Suture Staple Remplissage for Hill‐Sachs Lesions in the Beach Chair Position

open access: yesArthroscopy Techniques, EarlyView.
Abstract The addition of remplissage to arthroscopic Bankart repair in the presence of a Hill‐Sachs lesion can help decrease recurrence of anterior shoulder instability. The remplissage procedure often involves passage of suture from anchors in the Hill‐Sachs lesion to the extra‐articular side of the shoulder capsule followed by knot tying.
