The importance of the multiphase fluid dynamics for fouling mitigation in MBR systems has been widely acknowledged with air sparging having been applied commercially for about 20 years. However, the effects of air scouring are still not fully understood since the transient orthogonal and parallel flows as well as turbulent eddies created by bubbling generate complex hydrodynamic flow fields in ...

The recent challenge in textile supply chain management is the development of collaboration network which accommodates diverse concerns of various participants while explicitly recognizing interdependencies and promoting effective relationship management. This study is designed to suggest a collaboration network model for textile industry and apply it to establish a desirable framework for the ...

one of the most concerning issues for researchers is to predict the shape and dimensions of the scour pit nearhydraulic structures such as the base of bridges, weirs, valves and stilling basins due to both financial and humanhazards induced by destruction of the structure. as the scour issue has its own complexity in relation to themultiplicity of effecting factors on it, in this study therefor...

Submarine pipelines are appropriate method for transmission of oil and gas from sea bed. Free spans may occur due to the natural uneven seabed or by under-scouring. Vortex Induced Vibration (VIV) can happen in such free spans at high Reynolds number. Resonance occurs if the frequency of vortex shedding is close to the pipeline’s natural frequency leading to its fatigue that can break the pipeli...

During the past 15 years NASA has taken the lead role in exploiting the benefits of textile reinforced composite materials for application to aircraft structures. The NASA Advanced Composites Technology (ACT) program was started in 1989 to develop composite primary structures for commercial transport airplanes with costs that are competitive with metal structures. As part of this program, sever...

This study constructs a digital elevation model of the coastal waters Shandong Peninsula using GIS-based interpolation methods to investigate 15-year characteristics seabed scouring and siltation. It utilizes depth data Peninsula’s offshore area between 2004 2006 2017 2019. The results indicated that coastal-water is characterized by integral siltation local point scouring. In addition, northwe...

Two textile research projects (one completed and one ongoing) are described, where physical inspirational tools are developed and tested with the aim of stimulating textile creativity and invention, i.e. the use of textile materials in new kinds of products, thus bringing textiles into new contexts. The first research project (completed) concerns how textile designers use new responsive materia...

BACKGROUND AND SUMMARY Thousands of workers are engaged in textile industry worldwide. Textile industry involves the use of different kinds of dyes which are known to possess carcinogenic properties. Solvents used in these industries are also associated with different health related hazards including cancer. In previous studies on textile and iron industries, the authors have reported genotoxic...
