BACKGROUND/AIM The aim of this study was to reveal the tetanus immunization status of diabetic patients and to determine whether diabetic patients with foot ulcers have different TIG levels. MATERIALS AND METHODS A cross-sectional study was designed that included diabetic patients with foot ulcers (n = 30) and diabetic patients without ulcers (n = 30). The groups were compared for serum TIG l...

Minor problems arising from optimizations by welding of fixed prostheses frameworks can be identified by macroscopic and microscopic visual inspection. The purpose of this study was to highlight the visible discontinuities present in the laser welds of dental Ni-Cr alloys. Ni-Cr base metal alloys designated for fixed prostheses manufacture were selected for the experiments. Using cast plates, p...

A multi-response optimization problem was developed in search of an optimal parametric combination to yield favorable bead geometry of bead-on-plate weldments produced by submerged arc welding. Taguchi’s L25 orthogonal array design was employed to optimize the results within experimental limits. The objective functions were selected in terms of responses of bead geometry, viz. height of reinfor...

This study investigates a parametric multi-objective optimization of the Tungsten Inert Gas-Metal Gas (TIG-MIG) hybrid welding AISI 1008 mild steel joints. A combined grey relational system theory and Taguchi method was used for process towards achieving set parameter that maximizes both ultimate tensile strength 0.2% yield structural applications. An L-9 orthogonal array based on adopted exper...

The main components of the LHC, the next world-class facility in high-energy physics, are the twin-aperture highfield superconducting cryomagnets to be installed in the existing 26.7-km long tunnel. After installation and alignment, the cryomagnets have to be interconnected. The interconnections must ensure the continuity of several functions: vacuum enclosures, beam pipe image currents (RF con...

Arc welding is an important joining process widely used in many industrial applications including production of automobile, ships structures and metal tanks. In welding process, the moving electrode causes highly non-uniform temperature distribution that leads to residual stresses and different deviations, especially buckling distortions in thin plates. In order to control the deviations and in...

Microplasma welding is a less expensive alternative to laser welding in dental technology. The aim of the study was to highlight discontinuities present in the microplasma welded joints of dental base metal alloys by visual analysis. Five base metal alloys designated for fixed prostheses manufacture were selected for the experiments. Using these plates, preliminary tests were conducted by micro...
