Abstract:

The road is an infrastructure that is often passed by the community. If there is damage, it will significantly disrupt community activities; for example, road conditions become jammed. This is necessary for the Public Works and Spatial Planning Office of the City of Cirebon to handle the road repairs, but in carrying out repair planning, there are obstacles, one of which is the difficulty in determining priority for road repairs with limited funds from the center. This research decision support system using the Promethee II method aims to find accurate results that are useful in determining pr

Abstract:

Ankle sprains can lead to chronic lateral ankle instability caused by an injured anterior talofibular ligament (ATFL), and surgery is often required when conservative treatments fail. BROSTROM surgery is considered the gold standard and has a definite curative effect. Advancements in arthroscopic surgery and improvements in implanted anchors have led to an increase in ATFL repairs using arthroscopic surgery. Arthroscopic AFTL repair is less invasive, and patients could experience faster recovery compared to open AFTL repair. To simplify the complicated suture-passing processes in arthroscopic

This will slow down the work process because UPT MR will carry out another evaluation which will then be reported to Deputy Director 2 for improvements.

Abstract:

Flush repairs to military aircraft are expected to become more prevalent as more thick skin composites are used, particularly on the surface of the fuselage, wings and other external surfaces. The use of these repairs, whilst difficult to manufacture provide an aerodynamic, ???stealthy??? finish that is also more structurally efficient than overlap repairs. This research was undertaken to improve the design methodology of scarf repairs with reduced material removal and to investigate the damage tolerance of scarf repair to low velocity impact damage.

Abstract:

Repairs of gas turbine buckets (blades) are currently limited to the upper tip region of the airfoil where operating stresses are commonly low. This limitation is predicated upon the use of low strength welding filler materials and the use of high energy welding processes such as gas tungsten arc welding (GTAW). When bucket damage is located within parts of the airfoil subjected to higher stress levels, buckets are often scrapped or replaced, costing utilities/independent power producers millions of dollars. Advanced repair techniques which allow repairs at higher stress regions of the bucket

Abstract:

More than 57.2 million episodes of musculoskeletal injuries were recorded in 2004 in the United States, costing the US economy more than $254 billion [1, 2]. Approximately 45% of these are tendon, ligament and joint capsule related injuries [3]. Tissue engineering approaches have emerged as an attractive alternative to conventional and oftentimes ineffective treatment methods. Implanting MSC-seeded collagen tissue engineered constructs (TECs) in the central defects of patellar tendon (PT) has significantly improved repair biomechanics compared to natural healing as well as acellular repairs in

Abstract:

Leaking gas industry valve stem seals are recognized as a substantial source of atmospheric methane, which is a greenhouse gas. Newly proposed regulations include methane alongside volatile organic compound emissions, with leak detection and repair requirements. If a leak is identified a first attempt at repair must occur no later than five calendar days after identification, or else be justifiably delayed. The objective of this report is to review valve technology and methods used to address in-situ valve stem leak repair that offers an economical solution with reduced service disruption. A w

This report presents a review of flexible pavement pothole-patching materials, equipment, and techniques within Illinois Department of Transportation as well as other transportation agencies in the United States. The research team conducted a literature review to examine recent studies and available state department of transportation guidance on pothole patching. Overall, this review revealed a lack of recent studies on this topic, and a greater need for them. The review also revealed that most states do not have centralized guidance for pothole repair best practices. The researchers also met

Full text

Abstract:

Cellulosic-coated electrodes (primarily AWS EXX10-type) are traditionally used for "stovepipe" welding of pipelines because they are well suited for deposition of pipeline girth welds and are capable of high deposition rates when welding downhill. Despite advances in mechanized welding technology, development of low-hydrogen self-shielded flux-cored arc welding (FCAW) consumables, and substantial improvement of basic-coated low-hydrogen vertical-down shielded metal arc welding (SMAW) electrodes, manual pipeline welding using cellulosic-coated electrodes is still widely utilized throughout the

Abstract:

Population growth, urbanisatioon, and production-consumption patterns linked to a linear economy have resulted in a continuous increase in solid waste generation (UNEP. 2016). The construction sector, significantly contributing to GDP globally, is responsible for producing a specific type of solid waste known as Construction and Demolition Waste (CDW). CDW stems from excavation, construction, demolition, repairs, or improvement activities in buildings or civil works (Ministry of Environment and Sustainable Development, 2017a). Globally, approximately 10 billion tonnes of CDW are generated annu

Full text

Abstract:

The effectiveness of different coating removal techniques during investigative excavations was studied by a combination of laboratory testing and field investigation. During repair and investigative pipeline digs, a disproportional amount of time and effort is often spent removing old existing coating so as not to damage the pipe underneath. The necessity for examining the steel surface under the coating requires careful but thorough coating removal or else the important features on that surface will be lost. The objectives of this work were the following: Determine the relative effectiveness

Abstract:

The main focus of this research paper is on-media axon branching and adhesion investigation of neurons as stimulated by modulated potentials on micro-patterned gold substrate. Due to the prolonged and inefficient procedures of nerve repair, it is essential that we effectively incorporate different parameters and techniques as well as investigate cell-cell and cell-substrate interactions to explore new boundaries. This could lead to more operational options for nerve regeneration. Initially, the behavior of cell growth is first observed. 3T3 and Neuro2A cells are grown according to specific pro

Abstract:

Federal regulatory standards require repair of dents with depths exceeding 6% of the pipeline diameter and for dents exhibiting signs of mechanical damage interacting with secondary features. However, leaks have been known to occur at dents with depths less than 3% of the pipe diameter and dents interacting with secondary features have been known to survive in service for extended periods of time. With the improvement in ILI technologies, there is an increase in detection of shallow dents and shallow dents interacting with corrosion features and a large population of these features exist curre

This project analyzed public willingness to raise transportation revenues, public priorities for transportation spending, and public preferences for transportation revenue types using recent household travel surveys for the small urban areas of Billings and Missoula. The share of the public willing to pay more taxes or fees for transportation improvements was 44% in Billings and 36% in Missoula (including neutral or undecided responses). This level of public support for increased transportation revenues is perhaps higher than generally perceived by leaders reluctant to publicly support a gas t
