Processing of bulk metallic glass (BMG) foams, using melt infiltration techniques, is reported for the first time. Foaming methods based on infiltration of two types of pattern materials are described: investment of a continuous refractory yielding very low relative density structures (5% dense relative to the BMG), and investment of a discontinuous refractory pellet bed yielding higher relativ...

Peripheral blood leukocytes (PBL) from myeloma patients were studied for their capacity to lyse plasma cells from myeloma patients, benign monoclonal gammopathy (BMG) patients, and nonneoplastic disease patients. Plasma cells were isolated from bone marrow, labeled with 51Cr, and cultured with PBL isolated from patients with myeloma, BMG, or nonneoplastic disease, as well as normal individuals....

Processing of foams from bulk metallic glass (BMG) alloys, using melt infiltration techniques, is reported for the first time. Foaming methods based on infiltration of two types of pattern materials are described: investment of a continuous refractory yielding very low relative density structures (5% dense relative to the BMG), and investment of a discontinuous refractory pellet bed yielding hi...

PURPOSE To compare Buccal Mucosa Graft with Penile Skin Flap techniques in the management of anterior urethral diffuse strictures longer than 3 cm. MATERIALS AND METHODS Thirty seven patients with a mean age of 28.5 (range 5 to 50) years had been treated by these two techniques using the ventral onlay patch from February 1997 to March 2002. Patients' follow-up included physical examination, h...

By restricting the dilated deformation, surface modification can stimulate multiple shear banding and improve the plasticity of bulk metallic glasses (BMGs). Aimed at modifying the surface of BMGs by thin layers, a crystalline Ni coating with ultrafine grains was coated on the surface of a Ti-based BMG by electroless plating. With a thickness of about 10 μm, the prepared thin coating could effe...

The Piedade Granite (approximately 600 Ma) was emplaced shortly after the main phase of granite magmatism in the Agudos Grandes batholith, Apiaí-Guaxupé Terrane, SE Brazil. Its main units are: mafic mineral-rich porphyritic granites forming the border (peraluminous muscovite-biotite granodiorite-monzogranite MBmg unit) and core (metaluminous titanite-bearing biotite monzogranite BmgT unit) and ...

Introduction . Articular cartilage has a limited intrinsic capacity for repair, therefore, methods to repair or reconstruct osteochondral defects have been sought by many labs (). The search for the ideal cellular matrix has resulted in the development and testing of both artificial and natural scaffold materials(). Current cellular scaffolds, however, are limited by the presence of inflammator...

many investigators use bone matrix gelatin for bone induction but it is used rarely for repair of teeth defects. this study was designed to evaluate secondary dentin formation by endochondral bone matrix gelatin (e-bmg) in rabbit. e-bmg was prepared from tibia and femur of 4 deutsche-poland rabbits with average ages of 4-6 months. the prepared e-bmg was implanted in right incisor teeth pulps of...
