calligraphy in plaster molding has long been a unique platform for professional designers and decorative calligraphers due to the ease of molding the plaster and the longevity of the work. since the origin of the kufi alphabet used in plaster inscriptions is simplekufi, it is generallybelieved that the common letters must be drawn alike. however, as exemplified in the phrase under study, the mo...

prostatic intra-epithelial neoplasia (pin) is considered a precursor of invasive carcinoma, characterized by proliferation and anaplasia of cells lining prostatic ducts and acini. in this study, we applied the pin grading system on one-hundred cases of prostatic carcinoma and one-hundred cases of benign prostatic hyperplasia, then compared the results. 74% of prostatic carcinoma and 51 % of pro...

in this paper the traditional covering plaster of masonry buildings is supplied with polypropylene and steel fiber to enhance their seismic behavior. the plaster mix proportion is determined by some initial mortar tests. also, one story, single span masonry building specimen plastered with different mortars is tested on a shaking table 8 times under a seismic input and the performance of the sp...

PURPOSE To review the infection rate in 43 patients who underwent percutaneous Kirschner wire fixation for distal radius fractures. METHODS Records of 13 men and 30 women aged 25 to 86 (mean, 49) years who underwent closed reduction and percutaneous Kirschner wire fixation for unstable distal radius fractures were reviewed. Each fracture was fixed with 2 to 3 wires of 1.6-mm diameter. Kirschn...

An inner tube was inflated and then surrounded with plaster wool and plaster-of-Paris bandages. The plaster and the wool were next progressively divided. There was no significant reduction of the pressure inside the tube until both the plaster and the wool had been divided and separated from the inner tube along the entire circumference. These findings demonstrated that wool and plaster applied...

The physical properties of plaster bandages are a very important factor in achieving the basic functions of immobilization (maintaining bone fragments in the best possible position), which directly affects the speed and quality of fracture healing. This paper compares the differences between the physical properties of plaster bandages (mass, specific weight, drying rate, elasticity and strength...

Acrylic processing of waxed-up dentures is considered to be a crucial and technique-sensitive procedure. Polymethylmethacrylate (PMMA) has become the most commonly used material for denture bases since its introduction in 1937. The advantages of PMMA include excellent esthetic properties, adequate strength, low water sorption, low solubility, lack of toxicity, facility of repair, and constructi...

Orthopaedic casts are used to treat fractures, provide pain relief and support, and correct deformities (RCN 2000, Larsen 2002, Dandy and Edwards 2003, Nielsen and Ricketts 2005). Several different types of material are available for orthopaedic casts, including plaster of Paris, semi-rigid non-fibreglass (softcast), and a variety of resin-based synthetic materials such as rigid fibreglass. Pla...

OBJECTIVES To compare traditional plaster casts, digital models and 3D printed copies of dental plaster casts based on various criteria. To determine whether 3D printed copies obtained using open source system RepRap can replace traditional plaster casts in dental practice. To compare and contrast the qualities of two possible 3D printing options--source system RepRap and commercially available...
