RP is also known in another term such as layer manufacturing, direct CAD manufacturing, solid freeform fabrication and rapid prototyping and manufacturing (RPM). From these several terms for RP it can be drawn that its basic principle is actually “additive manufacturing.” It is because the 3D object is being formed by building layer by layer through adding, depositing or solidifying one or more materials in a horizontal layer-wise process (Heynick and Stotz, 2006). Lam et al (2002) described the rapid prototyping (RP) as “the process of creating three dimensional (3D) objects through repetitive deposition and processing of material layers using computer-controlled equipment … based on the 2D cross-sectional data obtained from slicing a computer-aided design (CAD) model,” (49). ...
 The whole model is completed by printing successive 2D profiles on a fresh layer of powder. The profiles of each layer are joined using the printed binder and completed after the removal of the unbound powder and this has been used extensively for the fabrication of drug delivery devices (Wu et al, 1996). Tissue engineers soon caught up and started using 3DP to design and fabricate scaffolds (Wu et al, 1996). Developments include the use of the technology combined with salt leaching technique to fabricate polymeric scaffolds using copolymers of polylactide-coglycolide (PLGA, 85L:15G) and a suitable solvent. Cylindrical scaffolds (F O 8X7 mm) and managed to achieve interconnected porous channels of about 800 ?m and microporosities of 45–150 ?m by using salt leaching. They were able to attach large numbers of hepatocytes on the scaffolds. In a study that investigated cellular reactions to pore size and void fractions based on 3DP fabricated scaffolds, cell proliferation was observed on the scaffolds but varied between cell types and the experimental parameters. The scaffolds used in the experiment had varying pore sizes of 38–150 ?m and void fractions 75% and 90% (Zeltinger et al, 2001). RP is far different from traditional fabrication because this technology is only possible through the aid of the computer which controls all the mechanical system in fabricating 3D objects. Traditional fabrication technique could include solvent casting, gas foaming, fiber bonding/ meshes, phase separation, melt molding, emulsion freeze drying, solution casting, and freeze drying. ...Download file to see next pagesRead More

...?The Greatest Show on Earth: The Evidence for Evolution, Richard Dawkins Chapter 3-6 Chapter three and four continues the explanation regarding evolution and the order of things; his further address’s the idea of dating and why that dating is a positive approach. He first begins using the accepted technique of layer dating with regards to plant growth and sedimentary layering. So first we need to address the idea of tree rings and we can turn to a popular Christian apologetics website and a paper published there by John Woodrappe, M.A. Geology, B.A. Biology where he states that the science involved with ring width measurements currently that show tree rings occur no more than once a year, and as a result this is something...

...Material Handling Policy Development due: Identification of the Health Hazards Any individual working with industries that use sulphuric acid as their raw material or manufactures of the acid itself must understand the dangers linked it. Manufacturers are required to make health hazard information presented on the product tag and material safety data sheet (MSDS). Identification of these health hazards such as irritation of the skin informs the users of what to do and not to do in relation to chemical handling. It also helps in minimizing cases of employees exposing him/herself to these hazards unknowingly (Seufert, 2014). Identification of the methods used to protect the...

Additionally, high-cost products mean that the organization will patent their technology, thus, ensuring that no other products are made with the same features; hence, lowering the value of low-cost materials. Moreover, making low-cost products will mean more clean-up, replacement, which decreases customer loyalty towards the products making the low-cost products wasteful.

The innovation can be made at first twostages of carpet life cycle (i.e., Raw materials, processing the raw material). If we just have to educate farmers in the particular context. If farmers would be educated with regard to this technological advancement, we can directly start the life cycle for manufacturing of carpet from third stage (i.e., combine ingredients) and so on. ii. Technological advancement practicing: Researchers have now developed an enzyme-based biological technology that paves the way for manufacturing carpets that are much lighter, sustainable, biodegradable,...

... Question There are many theories put forward to explain the process of evolution. However, the theory acknowledged by majority scientists is then theory of natural selection. The theory of evolution dates back to the ancient times of philosophers such as Anaximander. In order to explain this theory, Charles Darwin introduced the aspect of natural selection. Natural selection acts to save and aggregate minor invaluable genetic changes (Vincent and Joel 56). Assume a member of the species created a practical focal point (it developed wings and figured out how to fly). Its posterity would inherit that preference and pass it on to their posterity. The inferior (distraught) parts of the same species would slowly vanish, leaving just... such as...

...Frederick Sanger It is obvious, that if you intended to indicate the contribution of a person in science and in the proposed list will be Frederick Sanger you will definitely choose him. Frederick Sanger was a British biochemist who won the Nobel Prize for Chemistry twice. This is already a considerable achievement. Dr. Sanger firstly became famous for his work that was dedicated to deciphering the structure of insulin. He was the first scientist who understood from which amino acids and in which order is composed the insulin hormone, which then became a salvation for millions of diabetics worldwide. Two fundamental studies carried out in 1951 and 1952 guaranteed him the first Nobel Prize in 1958. Nevertheless, the real glory... Sanger It is...
