Influence of Processing Parameters on the Surface Roughness of Solid Wood Cut by Abrasive Water Jet

The surface roughness of pine, beech, and oak wood cut in the abrasive water jet (AWJ) system was evaluated for different processing parameters. Wood specimens were prepared in thicknesses of 18, 36, and 54 mm in both tangential and radial directions. Then the specimens were cut, applying three different feed speeds (50, 100, and 200 mm/min), three different abrasive flow rates (200, 300, and 450 g/min), and two different cutting liquid pressures (300 and 380 MPa) with the AWJ system. The R-a and R-Z roughness values were higher in the tangential cut for pine and oak specimens and in the radial cut for beech wood. Roughness values increased in all specimens with increases in the AWJ feed speed and the wood thickness. In contrast, with increased amounts of abrasive, R-a and R-Z values of the specimens decreased and surface smoothness tended to increase. Roughness values of pine and oak specimens generally decreased due to the increase in liquid pressure. However, an increase in the roughness of the beech specimens was determined. As a result, the feed speed and wood thickness were the most influential parameters on the roughness of specimens. In contrast, the cutting direction and liquid pressure showed less importance on the roughness.Research Fund of Duzce UniversityDuzce University [BAP-2017.07.01.521]The authors are grateful for the support of the Research Fund of Duzce University, Grant No. BAP-2017.07.01.521.WOS:0005557911000062-s2.0-8508845193

Mechanical performance of hybrid Ilizarov frames containing full-threaded Schanz screws

WOS: 000245725900016PubMed ID: 17424695Modification of circular Ilizarov frames is necessary to overcome the difficulties in pin positioning due to unfavorable anatomic site or local soft-tissue conditions. Hybrid frame configurations consisting of half pins or full-threaded schanz screws are widely used in clinical practice. This study compared the mechanical performance of hybrid frames and a standard system. One standard and five modified hybrid systems were tested under axial compression, four-point bending, and torsional forces. Systems modified with full-threaded schanz screws showed a higher stiffness than half pin modifications and exhibited a similar mechanical performance of a standard system

Toxic epidermal necrolysis associated with radiotherapy and phenytoin in a patient with non-Hodking's lymphoma: A case report

WOS: 000408480200013PubMed ID: 26900363Toxic epidermal necrolysis (TEN) is a disease which is characterized by fever and desquamation of the skin and mucosal membranes. It is usually related with drugs, especially aromatic anticonvulsants which are recognized as the most common cause of this disorder. Cranial irradiation may act as a precipitating factor along with anticonvulsants for the development of TEN. We report a 28-year-old patient with central nervous system (CNS) relapsed non Hodgkin lymphoma (NHL) who developed TEN after cranial radiotherapy and concurrent phenytoin treatment.
