1. Wright PS. in 1984 stated that there is sufficient evidence available for use of soft liner but because of its inadequate physical properties the use of soft liner is limited. The objectives of the study were: 1. Clinical success of the available soft liner material and their retrospective study. 2. The collection and measurement of data relating to a group of wearing soft-lined mandibular dentures for edentulous patients. 3. A three year longitudinal study of the clinical success of both…

Frank’s creation. The men behind the machine include roboticists Matthew Godden and Richard Walker: Alexander Seifalian is a professor of Nanotechnology and Regenerative Medicine at University College London. Seifalian created Frank’s organs using a polymer that is specifically designed to build implantable organs. created Frank’s artificial organs. Frank was created to resemble the University of Zurich’s psychology professor, Dr. Bertolt Meyer. Dr. Meyer was chosen as the human model for Frank…

Today in the multicultural society of the world, “Art is considered to be a powerful source to express a meaning or idea to an audience”, according to Jack Hanley, of Jack Hanley Gallery in New York. It is this meaning or idea that communicates to a viewer the individual artist’s intentions, beliefs, physical art making and unique ideas that are carried out. Two artists and their works that reflect this communication and consist of a range of different mediums include Lin Onus’s work’s “Fruit…

Matthew Wood Rough Draft Gene doping is defined as “The transfer of polymers of nucleic acids or nucleic acid analogues” by the WADA (World Anti-Doping Agency). Essentially gene doping is modification of a person’s genes in order to improve how they perform. This can be done several ways, however the most common method is the use of a vector. The gene that is to be inserted into the host is placed inside the capsule of a virus. The virus is able to spread throughout the tissue to be…

-Film coating involves the deposition of a thin film of polymer surrounding the tablet core It involves the conversion of a viscous liquid into a visco‐ elastic solid as a result of continual solvent evaporation Reasons for coating tablets: ¥ To protect tablet core from environment (e.g. light or moisture)…

Styrene (St, 99%) and methyl methacrylate (MMA, 99%) were obtained from Aldrich company. These monomers were first dried over calcium hydride, were purified by being passed through a column of basic alumina, and were distilled under reduced pressure. Ethyl 2-bromoisobutyrate (EBIB, 98%), copper (I) bromide (CuBr, 99%), copper (I) chloride (CuCl, 99%), and other chemical reagents were procured from Aldrich company and used as received. N-methylbis[2-(dodecylthio)ethyl]amine (SNS) was synthesized…

2. Materials and Methods: The keratin was extracted from Chicken feather which were collected from the local market of Raipur (21.14°N 81.38°E) Chhattisgarh, India. The 91% food grade alginate (sodium salt form) was purchased from Loba Chemie. The β-mercatpoethanol (mol. wt. 78.13) from LOBA Chemie, sodium dodecyl sulfate (SDS) (mol. wt. 288.38) and urea (mol. wt. 60.06) was purchased from Merck, and ethanol was purchased from Sigma-Aldrich. Antimicrobial strain of gram negative bacteria…

taken on creating the product and packing everything. The handle-grip is a simple three part piece presented wrapped by protective foam. You’ve a clamp, a grip and a wrist-strap, very much like the original S1. The clamp G1, which is made of an ABS polymer with metal inserts and rubber pads, is the same as the original, with the adjustable mechanism and rubber pads that allow it to fit virtually any mobile device. The difference, though is that the grip H1, which is bigger and makes it easier to…

Today I will be writing about the protein that I was assigned which was Structural Protein. What is your protein? What are they used for? They are used to build structural components of the body such as bones and cartilage. They are mostly found in larger cells. These proteins provide keratins, actin and support. I will be talking about why this protein is important and what does it do. The shape of a protei determines its function and there also a lot of different levels. An example of the…

The clear waters and sunny skies of Hawaii drifted out of sight as the plane back in route to New Jersey parted clouds during its ascent. When leaving an extraordinary location, it is typical for a melancholy feeling to arise, due to the realization that reality is eagerly awaiting our return. For many, leaving a beautiful island too soon or having their attendance at an international chemistry conference be cut short would bring these emotions. However, everything else seemed trivial upon…
