The design of multi stage deep drawing processes requires the evaluation of many process parameters such as the intermediate die geometry, the blank shape, the sheet thickness, the blank holder force, friction, lubrication etc..These process parameters have to be determined for the optimum forming conditions before the process design. In general sheet metal forming may involve stretching drawin...

BACKGROUND The exact mechanisms of action responsible for the effectiveness of silicone gel dressings are unknown, although it has been proposed that static electricity generated by friction could be the reason for their anti-scarring effects. OBJECTIVE We compared the efficacy of a cushion of silicone filled with liquid silicone gel reported to induce greater negative static-electric charge ...

One method of constructing lightweight concrete floors in residential dwellings is to use a trapezoidal profile steel pan as a permanent form for a relatively thin pour of concrete. The resulting structure has enhanced stiffness to weight ratio due to the composite action between the steel and concrete, and the inherent improved stiffness of the profiled cross section. However the floor is stro...

Silicone thermoplastic sheeting has been used successfully in the management of hypertrophic and keloid scars resulting from thermal burn injuries. A technique is described that incorporates silicone thermoplastic sheeting for fabrication of a compression face mask. This technique combines the moldability of thermoplastic splinting materials with the therapeutic surface of silicone, yielding th...

To date, silicone gel and silicone occlusive plates are the most useful and effective treatment options for hypertrophic scars (surgical and traumatic). Use of silicone sheeting has also been demonstrated to be effective in the treatment of minor keloids in association with corticosteroid intralesional infiltration. In our practice, we encountered four problems: maceration, rashes, pruritus and...

The Louisiana Department of Transportation and Development (DOTD) has over 400,000 traffic signs in its inventory. These signs vary widely by their sheeting grade, age, color, orientation, and proximity to the roadway edge. In a typical year the DOTD replaces about 60,000 of these signs because they are beyond their service life or have been damaged. Currently, the DOTD does not have a systemat...

Many governments all over the world are trying to fulfill second basic need of shelter human being by affordable quality housing. Roofing is an important part building in structural, architectural and aesthetic point view. Due rapid increasing different types industry as well growing cities population, thin shell profiled steel sheet roofing element using for structural purpose. Its lightness, ...
