Abstract:

The different soil anti scourability in the lower reaches of the Yellow River leads to different scouring and retreating speeds, which has a great influence on river regime evolution. Through the incipient motion scouring test of cemented cohesive soil in the lower reaches of the Yellow River, the physical phenomena of the incipient motion of cohesive soil were expounded, the scouring rate of cohesive soil was calculated, and the relationship between the scouring rate and its influencing factors was established. The results show that when the moisture content of cohesive soil is 43%~61%, the s

Abstract:

The paper describes a method of scouring sheep wool using ultrasound.The inspiration to start work on the use of ultrasound in the process of scouring sheep wool was positive results that had already been achieved for alpaca wool. Due to the fact that sheep wool has many more impurites than alpaca wool, the scouring process is divided into two stages. The first involves the removal of faeces from the wool, which may be up to about 35% of the impurities of sheep wool, while the second stage involves the scouring cycle, wherein the remaining impurities are removed.

Abstract:

Bridge pier as a crucial part of a bridge is used for various marine and transportation purposes. Local scouring around the bridge pier is a prominent cause which leads to the failure of the bridge system. scouring around the bridge pier is caused due to the effect of vortices created by water current. To prevent scouring we have to design the countermeasures and also maintain the sediments which are erodible. This review examines both type of countermeasure devices. Measures such as to divert the flow or to strengthen the river bed. Use of slot can reduce the scouring to 20% and with combinat

The bio-scouring of cotton using protease and pectinase produced from Bacillus subtilis was investigated. Protease and pectinase were produced from Bacillus subtilis in a liquid medium using the submerged fermentation technique.

The optimum scouring temperature for both enzymes was between 40 °C and 50 °C, with pectinase bio-scoured fabric showing 15.5% weight loss while protease bio-scoured fabric had 14.3% weight loss.

Abstract Experimental tests were carried out to investigate the effective scouring parameters downstream from stepped spillways with different flow rates and step sizes. The results indicated that the flow regime plays an important role in scour-hole dimensions such that the minimum scouring depth happens in the nappe flow regime. Moreover, step size and tailwater depth are essential parameters for maximum scouring depth. Increasing tailwater depth from 6.31 cm to 8.54 cm and then to 11.82 cm decreases the scouring depth by 18.56% and 11.42%, respectively. These alterations also decrease the s

In recent years, heavy rainfall disasters have caused frequent damage to bridge piers due to scouring and have resulted in the fall of bridges in many areas in Japan. The objective of this study was to investigate the effect of local scouring around the downstream of the piers on the local scouring around the center of the river flowing at an angle to the piers. It was found that when the center of the river flows at an angle to the piers, the scouring area becomes wider from the upstream to the downstream of the piers because of the longer inhibition width of the piers positioned perpendicula

Abstract:

The use of protease in the raw wool scouring process was investigated. Both native protease and an enlarged protease prepared by chemical modification were used. It was demonstrated that enzymatic treatment with protease in the scouring process (bio-scouring) can achieve cleaning of the fibre and modification of the cuticle layer leading to shrink-resistance. A reduction of lipid content was found and led to an improvement in dyeability of the fibre.

Abstract This article uses the work of brand theorists and New Zealand–based cultural critics to examine the circumstances that created the “Hobbit Law,” a New Zealand law aimed at busting local film industry unions. Branding logics created a struggle for authenticity around the importance of Middle-earth to New Zealand's national identity in the twenty-first century. This hybrid identity was then articulated as something that stood against labor actions by film industry workers, culminating in citizen marches against local labor. It closes by exploring ways that the importance of the brand as

Abstract This experiment evaluated the impact of various dietary treatments on the growth and scouring of piglets post-wean and following an enterotoxigenic Escherichia coli F18 infection (ETEC). A total of 240 pigs (PIC 337 x 1050, Genus, Henderson, TN) were randomly assigned to 40 mixed-sex pens (6 pigs/pen) for a 6-wk experiment. At arrival, all pigs were genotyped for fucosyltransferase (FUT1). Pens were assigned to five dietary treatments: NC (standard nursery diet without Zinc or carbadox, 22.31% CP, 1.46 SID Lys in Period 1); PC (NC + 3,750 ppm zinc oxide and carbadox); LCP (NC with low

Abstract:

Starch sized 100% cotton woven fabrics need desizing, scouring and bleaching treatments prior to coloration and finishing. Traditionally, alpha-amylase-based enzymatic desizing and combined scouring and bleaching with an alkali, surfactant and H2O2 are used. Constant research is conducted on combining the desizing, scouring and bleaching processes into a single step by many researchers. This paper aims at combining enzymatic desizing and alkaline H2O2 scouring cum bleaching with a surfactant and stabilizer. The treatment resulted in efficient desizing, scouring and bleaching, leading to excell

Excellent performance is necessary for compressor blade when aircraft engine serves in harsh environment, where it will go through scouring from jet-stream and extraneous sand, shaking of blades and corrosion from corrosive medium, taking moisture, salt, SO2 for example. Due to the shortage of scouring resistant and anti-corrosion property, shedding of damaged coating is a fundamental reason for the breakdown of aircraft engine blades, which is also the technique bottleneck that hinders the engineering application of compressor blades.

Abstract:

Scouring is one of the important issues that caused damage to the structures. Failure due to local scour has inspired many researchers to study the cause of scouring and to predict the maximum scouring depth around the bridge pier. Numerical simulation is proposed as an effective tool for monitoring the depth of scouring to manage the stability and safety of the bridge. Flow-3D is an accurate, fast, proven CFD software that can solve the toughest free-surface flow problems. However, the guideline information of this software is limited.

Abstract:

In order to study the anti-scouring performance under the ecological concrete slope protection method, tall fescue was selected for vegetation experiments and anti-scouring experiments to analyze the effect of anti-scouring performance under different slope, different rainfall and different concrete thickness conditions, and concluded that the runoff erosion increases with the increase of slope and rainfall, while the concrete laying thickness has little effect on the runoff erosion. It also provides new research ideas and research directions for engineering applications.

In this paper, scouring shear failure theory is optimized based on the gangue slope near the thermal power field in Baiguo Town, Panzhou City, Guizhou Province. Based on the particle flow PFC (particle flow code) 3D fluid–solid coupling method, the scouring failure mechanism of ditch no. 5 of the gangue slope is comprehensively analyzed from the perspectives of the failure mode, displacement, motion track, and stress–strain. We consider the scouring shear theory in respect of (c, φ); this theory is dominated by two types of scouring intensity factors and can effectively explain the internal me
