Abstract:

As the number of calling ships in container terminals rises, waterways in some harbors have become the major constraint to the overall performance of the ports service. By constructing anchorages, the congestion that happens frequently in harbor can be effectively eased, thus the traffic capacity is greatly enhanced. The purpose of this paper is to study the impact of anchorage number on waterway traffic capacity and provide theoretical foundation when deciding the anchorage scale. A simulation method with consideration of anchorages is adopted to analyze the vessels entering and departing pro

Introduction. Direct, rigid indirect, and nonrigid indirect absolute anchorages using temporary anchorage devices (TADs, mini-implants/miniscrews) can provide promising opportunities for challenging, yet common, orthodontic tooth movements such as molar protraction. Rigid rectangular wire and ligature wire are the most common methods of attaching a tooth to a miniscrew in indirect anchorages. We aimed to provide a comparison of the rigidity of the connecting wire in terms of stress on the miniscrew, the anchorage loss, and the risk of root resorption using finite element analysis (FEA).

Abstract:

Anchorage control is one of the most essential keys for success in clinical orthodontics. Anchorage loss is a primary concern associated with orthodontic procedures. Numerous devices have been proposed and used for over a century to get the appropriate anchorage. Extraoral anchorages such as headgears or facemasks are the most effective tools but are limited because their effectiveness depends on patient compliance. Using skeletal anchorage, such as Temporary Anchorage Devices (TADs), to retract anterior maxillary teeth is an old technique developed in 1945. Despite their small diameter and sh

Facemasks using tooth-borne anchorages have been used primarily for the treatment of Class III malocclusion with maxillary undergrowth. However, when using a tooth as an anchorage, if the stability of the tooth used as an anchor is weak, the anchoring function may fail as the tooth tilts. Meanwhile, the use of skeletal anchorages such as implants, mini-implants, and mini-plates has been claimed to minimize the side effects of using dental anchorage.

Combined with the calculation results, the analysis on the mechanical characteristics is carried on by building the finite element model of rock bolt crane girder with different anchorage length of bolt. The analysis results indicate that the bearing characteristics of rock bolt crane girder are not improved significantly with the increase of anchorage length when the anchorage length of bolt exceed

Abstract:

In this study, we proposed a novel composite anchorage that considers the anchoring performance and dimension simultaneously. The design concept of this composite anchorage was first introduced, followed by comparison with the traditional inner-cone bond-type anchorage and traditional composite anchorage through theoretical and experimental methods. Then, a parametric study was conducted to determine the influence of different parameters on the anchoring performance, and the optimal design parameters were recommended according to the finite element (FE) and test results. Finally, the practicab

Abstract:

Gripping prestressed carbon fiber-reinforced polymers (CFRPs) in structural strengthening applications is challenging due to CFRPs’ susceptibility to lateral loading. This paper presents a reliable and reusable wedge anchorage for gripping CFRP plates that are 50 mm wide and 1.2 mm thick. The cylindrical anchorage, which is 75 mm long and 76.2 mm in diameter, consists of an external steel barrel, two internal steel wedges, and two soft copper sleeves. The barrel-wedge interface is designed using an innovative arc–linear configuration, through which the desired stress distribution is attained,

ABSTRACT In recent times, the use of miniscrew implants to obtain absolute anchorage has gained momentum in clinical orthodontics as rigid anchorage modality. Miniscrew implants offers many advantages when used as temporary anchorage devices like, easy placement and removal, immediate loading, can be used in a variety of locations, provide absolute anchorage, economic and requires less patient cooperation. This makes them as a necessary treatment option in cases with critical anchorage that would have otherwise resulted in anchorage loss if treated with conventional means of anchorage. The aim

Abstract:

The anchorage of structures is a crucial element of construction, both for humans and animals. Spiders use adhesive plaques to attach silk threads to substrates. Both biological and artificial adhesive structures usually have an optimal loading angle, and are prone to varying loading situations. Silk anchorages, however, must cope with loading in highly variable directions. Here we show that the detachment forces of thread anchorages of orb-web spiders are highly robust against pulling in different directions. This is gained by a two-step back-and-forth spinning pattern during the rapid produc

ABSTRACT Efficient anchorage control is one of the important requisites for successful orthodontic treatment. The conventional means of anchorage control have been the use of transpalatal /lingual arch and palatal button but disadvantage is they do not provide absolute anchorage. Though the use of headgear provide efficient anchorage control, the patients are not compliant in using a headgear. Orthodontic implants have provided us with noncompliant and efficient means of anchorage control. This article traces the journey of development of implants as temporary anchorage devices.

Abstract:

Splitting grouting is widely used to reinforce unfavorable soil stratum. Inclined steel grouting pipe is a type of structure which can achieve splitting grouting in soil stratum. It has been successfully utilized in argillaceous sandstone stratum, but its application in loess stratum has rarely been studied directly. This research aims to compare and analyze the bearing capacity and effective anchorage lengths of inclined steel grouting pipes with anchorage lengths of 6 m, 9 m, and 12 m. Firstly, bearing capacity of inclined steel grouting pipe was compared with that of ordinary grouting pipe.

Abstract:

ABSTRACT To ensure successful treatment and to prevent undesired tooth movements, it’s essential to manage reciprocal forces effectively. Anchorage control becomes particularly crucial in cases involving extractions, where it can help prevent unwanted tooth movement. However, during treatment, there’s a risk of anchorage loss, which can undermine the treatment objectives. Therefore, it’s imperative to monitor molar movement and assess for anchorage loss throughout treatment.

<strong><em>Background:  </em></strong><em>An adequate anchorage is often challenging in orthodontics and dentofacial orthopedics. The ability to control all the aspects of tooth movement is limited. The inadequate mechanical system to control anchorage leads to anchorage loss of the reactive unit. The conventional; Extraoral (headgear) and Intraoral (transpalatal arch) anchorage system is doubtful in providing absolute anchorage. Therefore, the need for orthodontic treatment that maximizes anchorage control and minimizes patient compliance requirements has led to the development of impla

Abstract The passive safety of the vehicle is ensured by designing optimized restraint systems to protect the occupants during the accident. The safety-belts have the role of restraining the occupants of the car on the seat during an impact or in the event of a rollover. Their retention prevents or minimizes the impact between the occupants and the interior components of the passenger compartment. Two simplified models of seat structures are proposed to determine the strength of the safety-belts anchorages. The test of the anchorage for safety-belts of the two seat models is performed in accor
