Metal forming processes, compared with machining ones, reduce production steps and increase manufacturing speed in addition to saving raw material. In this paper, forming process of column of a steering mechanism is investigated by finite element analyses and experimental tests; and optimum die design parameters are found. Forming process parameters including die opening angle, bearing length, ...

five cases of giant cell tumor of the lower end of radius are reported. three of the patients were women and two were men, the youngest of the patients was 18 years old and oldest 37 years. en bloc resection followed by reconstructive procedures were performed in three of the cases with good results.

Euclidean distance matrices (EDM) are symmetric nonnegative with several interesting properties. In this article, we introduce a wider class of called generalized (GEDMs) that include EDMs. Each GEDM is an entry-wise matrix. A not unless it EDM. By some new techniques, show many significant results on can be extended to matrices. These contain about eigenvalues, inverse, determinant, spectral r...

Produktionen mit komplexen Materialströmen lassen sich ohne Materialflusssimulation – im Folgenden Simulation genannt nicht Detail analysieren oder verbessern. Der für Simulationen typischerweise hohe zeitliche Aufwand hindert Unternehmen am profitablen Einsatz. Das Tool „Miori Production Control“ unterstützt die Analyse komplexer Produktionszusammenhänge durch den Vergleich von unterschiedlich...

This paper analyses the contribution of food processing industries in Spanish regional development. The agrofood industry is one of the most important industrial sectors in Spain and, in recent years, it has been an important component in the development of rural áreas. Factors affecting the location of food industries and changes taking place after accession to the European Community (EC) are ...

In this research, optimization process of axisymmetric extrusion dies is proposed. Plastic zone is analyzed using finite element method in the Eulerian system with flow formulation. The die profiles are defined by Bezier curves with six control points. Two effective functions are considered in this research; standard deviation of the strain rate and the rate of energy consumption during extrusi...

It is well known that approaching death accelerates cognitive decline. The converse issue, that is, the question of whether rapid declines in cognitive ability are risk factors for imminent death, has not been investigated. Every 4 years between 1983 and 2003, we gave 1,414 healthy community residents who were aged between 49 and 93 years the Heim AH4-1 test of fluid intelligence. A modified An...

Sensitivity analysis » The results of one way sensitivity analysis are shown in Fig 3. ICUR was most sensitive to the cost of Gefitinib. Other important parameters identified include PD to Die rate, SD to PD rate and utilites values for all the responses. Varying the PFS HR for CP also affected the ICUR. Characteristic Gefitinib (N=124) Age – Mean (± SD) 67.2 ± 10.4 Male 20.2 % Female 79.8 % Me...

introduction: distal radius fractures are a common traumatic injury, particularly in the elderly population. in the present study we examined the effectiveness of ultrasound guidance in the reduction of distal radius fractures in adult patients presenting to emergency department (ed). methods: in this prospective case control study, eligible patients were adults older than 18 years who presente...
