MORPHOLOGICAL AND STRUCTURAL ASPECTS USING ELECTRONIC MICROSCOPY AND IMAGE ANALYSIS OF IRON POWDERS OBTAINED BY WATER ATOMIZATION PROCESS

Quality of metal powders depends on manufacturing process and heat treating parameters. Among the physical, mechanical and structural characteristics of powders, the average particle size, size distribution, particle sha...

INVESTIGATION OF OPTICAL PROPERTIES OF Sb₂S₃ THIN FILMS

Thin films of SbS have been deposited by vacuum evaporation technique onto highly cleaned glass substrates under vacuum of the order 10 torr. The structure of the films was determined by their X-ray diffraction patterns...

Z-VALUED FUNCTION ON SEMIGROUPS, Z-VALUED SEQUILINEAR FORMS

USE OF THE MEDIAN IN THE ANALYSIS OF EXPERIMENTAL DATA

The concept of median is defined. The advantage of the median in special cases and the comparison with the classical arithmetical mean and weighted mean are presented. The case of discrepant results is analyzed. The calc...

INTER-ELEMENT RELATIONSHIPS FOR SOILS AROUND A FERROUS METALLURGICAL PLANT

The main objective of this paper is to establish inter-element relationships for soils around the Iron and Steel Integrated Works (ISIW) at Galati, Romania, using Energy Dispersive X-Ray Fluorescence (EDXRF) atomic techn...
