  • The electrospinning technique for the scaffolds designing utilizes the electrostatic force for the production of polymeric fiber ranging from nanoscale to microscale. This process is control by high intensity electric field between two electrodes having electric charges of opposite polarity. One electrode is placed in the polymer solution and other is placed in collector. Generally polymer solution is pumped as result in forming a drop of solution.

  • More than 200 polymers are used for electrospinning like silk fibroin (Zarkoob et al., 2004; Sukigara et al., 2003; Jin et al., 2004), collagen (Mathews et al., 2002), chitosan (Ohkawa et al., 2004), gelatin (Ma et al., 2005) etc. In the field of tissue engineering electrospinning technique is applied for the preparation of nanofiber scaffold design. The process is very versatile in terms of use of polymers, non-invasive and does not require the use of coagulation chemistry or high temperature for fiber generation.

  • Int J Adv Manuf Technol (2007) 34:496–515 DOI 10.1007/s00170-006-0628-x ORIGINAL ARTICLE A scaffolding architecture for conformal cooling design in rapid plastic injection moulding Received: 4 August 2005 / Accepted: 25 March 2006 / Published online: 8 June 2006 # Springer-Verlag London Limited 2006 Abstract Cooling design of plastic injection mould is important because it not only affects part quality but also the injection moulding cycle time. Traditional injection mould cooling layout is based on a conventional machining process.

  • Particulate leaching is one of the popular techniques that are widely used to fabricate scaffolds for tissue engineering applications (Ma & Langer, 1999; Lu et al, 2000). Salt, wax or sugars known as porogens are used to create the pores or channels. Here salt is grounded into small particles and those particles that have desired size are poured into a mold and filled with the porogen. A polymer solution is then cast into the salt-filled mold. After the evaporation of the solvent, the salt crystals are leached away using water to form the pores of the scaffold. The process...

  • This is because the extent of damage of the beam members using design solutions at 800 gal 2 at 350 girls, while the beam member by using design solution at 750 gal is not damaged until the seismic force at 800 gal. Since the repair beam member requires scaffolding and other construction works even if the damage is small, repair costs higher than for the column members.

  • A series of RNA-cleaving or DNA-cleaving DNAzymes have been obtained by in vitro selection. However, engineering an allosteric DNAzyme with dual RNA-cleaving and DNA-cleaving activities is very challenging. We used an in vitro-selected pistol-like (PL) DNAzyme as a DNA scaffold for designing a DNAzyme with dual catalytic activities.

  • Whereas test design, even when supported by tools, requires insight and ingenuity in similar measure to other facets of software design, test execution must be sufficiently automated for frequent reexecution without little human involvement. This chapter describes approaches for creating the run-time support for generating and managing test data, creating scaffolding for test execution, and automatically distinguishing between correct and incorrect test case executions.
