Dental trauma is more common in young patients and its sequelae may impair the establishment and accomplishment of an adequate treatment plan. This paper reports a case of complicated crown-root fracture in a young adult that was treated using adhesive tooth fragment reattachment and orthodontic root extrusion. Considering the time elapsed to follow up, the fracture extension, the amount of rem...

In our previous paper [Watano S. et al., J. Powder Technology Japan, 37, 362-370 (2000)], a novel compaction tester was developed to quantitatively evaluate the water dispersion condition of a wet kneaded mass prepared by a paddle type kneader. It has been demonstrated that the physical properties of pellets prepared by extrusion granulation after the kneading can be well predicted by the press...

Cyanobacteria are an important source of natural products. In this article, we briefly review the responses of cyanobacteria to different stresses. Abiotic stresses (temperature, salt, heavy metals, metalloid and ultraviolet (UV) influence cell growth and metabolism in cyanobacteria. Salt stress is a major abiotic factor that decrease...

The work examines the process of cold three-dimensional stamping, which is a very effective method manufacturing blanks for machine parts. When using extrusion, high-cost stamping equipment wears out quickly and defects appear on finished products. development rational technological processes helps to solve tasks expanding possibilities extrusion by reducing specific force perceived punches, fi...

Abstract. Friction Stir Extrusion (FSE) is an innovative direct-recycling technology developed for metal machining chips. A rotating die plunged into a cylindrical chamber containing the material to be recycled during procedure. The die's stirring action causes strong bonding, enabling back extrusion of full dense rod. One technology's major flaws process' discontinuity, which limits volume ext...

AIM The aim of this study was to assess whether significant meniscal extrusion of more than 3 mm or of even lesser degrees of extrusion could be considered significant. We also aimed to determine the morphology of tears that are most likely to be associated with significant extrusion. Study design and material. The study was done retrospectively on a group of 202 patients (157 males and 45 fema...

The extrusion of section from round billet poses a great challenge for theoretical modeling of the process using upper bound method. The greatest difficulty in three-dimensional upper bound method is to determine kinematically admissible velocity field. The SERR (Spatial Elementary Rigid Region) technique is fairly applicable for analyzing extrusion of sections having re-entrant corners. A modi...

Abstract Extrusion method has been utilised in a variety of product-processing units such as metal casting and food processing. The process extruding is relatively fast reproducible, more importantly, can benchmark shear resistance extruded materials. These advantages have propelled researchers to practice the extrusion determine soil properties, e.g. Atterberg limits strength. Although mechani...
