A novel electrochemical cell has been designed and built to allow for in situ energy-dispersive X-ray diffraction measurements to be made during reduction of UO2 to U metal in LiCl-KCl at 500°C. The electrochemical cell contains a recessed well at the bottom of the cell into which the working electrode sits, reducing the beam path for the X-rays through the molten-salt and maximizing the signal...

tepe sagzabad, a site situated on the qazvin plain of north-central iran, was excavated from 1970 to 1998 by the institute ofarchaeology of tehran university. recent excavations by h. tala’i (1997-1999) yielded some metal artifacts dating to theearly iron age. ten of these copper-based samples were investigated using inductively coupled plasma optical emissionspectroscopy (icp-oes), scanning el...

In this paper, Computer Aided Designing (CAD) in conjunction with Rapid Tooling is applied to design and produce forming tools (punch and die) for stretch-formed jewelry (generated on thin sheet metal on top of which jewelry patterns are raised with forming tools by stretching the sheet metal beyond its elastic limit. The work presents a parametric voxel based CAD paradigm for modeling of such ...

aim and background: the present study aimed to determine the relationship between role clarity and job adjustment among staff of isfahan university of medical sciences. this objective was followed regarding the impact that awareness of staff in organizational and vocational tasks and roles could have on their job adjustment. methods and materials: in a cross-sectional study, 242 staff of isfaha...

Improving the efficiency of technological tillage methods is primarily associated with developing existing tools and creating new types working for machines. Tillage improvement depends on correct choice most energy-efficient belonging to same class process. This research aims develop scientific baselines choosing different structural designs based criteria power consumption quality shallow til...

Abstract This paper explores the possibilities to use laser-based additive processes make, surface treat and repair/remanufacture tools, dies molds for cold working, hot injection molding. The failures encountered in these applications are described. materials used conventionally laser accounted for. properties of made by Laser-based Powder Bed Fusion (L-PBF) as good some cases better than thos...
