the komshecheh barite-fluorite deposit is the product of epigenetic hydrothermal mineralizationin dolomitized limestone of middle triassic age. the deposit is structurally and lithologically controlled andoccurs predominantly as bedded stratabound replacement sheets, although the veins and solution-collapsebreccias constitute important modes of occurrence. brecciation, dolomitization, silicific...

abstractepidermal inclusion cysts are uncommon in the breast, but the consequences can besevere when these cysts occur in the breast parenchyma. here, we report two suchcases. the patient in case 1 was an 37-year-old woman with a 3-cm palpable mass inthe right breast. mammography revealed a round and smoothly outlined mass, whichindicated a benign tumor, and sonography showed an irregularly sha...

present study determines not only the total amounts of metals (cr, cu and pb) in superficial agricultural soil of sistan area in eastern iran, but also the chemical partitioning of these elements in seven statistically selected cases. the analysis was run for local soil, soil treated by non-contaminated organic, compost and chemical fertilizers as well as soil treated by metal-contaminated fer...

a 25 year-old construction worker underwent neck laceration following penetrating neck trauma in a falling incident. the 3rd tracheal ring was injured which was initially repaired and the patient was discharged in good general condition. (figure 1 shows the patient’s neck view after discharge from hospital).two months later the patient was again admitted due to provocative coughing and a metal ...

background enterococci have emerged as more virulent and multidrug-resistant in community and hospital settings. the emergence of vancomycin resistant enterococci (vre) in hospitals has posed a serious threat to public health. the widespread use of antibiotics to treat vre infections has resulted in the development of resistant forms of these organisms. conclusions among the nanoparticles, zno ...

In recent years, destructive earthquakes have shown the deficiencies of the existing buildings. One of the most effective mechanisms for dissipating the earthquake energy is inelastic deformation of the steel components. The objective of this research is to study the application of metallic dampers for dissipation of the earthquake energy and to investigate the behavior of concrete structures i...

Systematic changes in composition were employed to increase the notch toughness of a variety of Fe-based Bulk Metallic Glasses (BMGs). The Fe50Mn10Mo14Cr4C16B6 BMG possessed very high hardness (e.g. 12GPa) but very low notch toughness (e.g. 5.7MPam) at room temperature, consistent with fracture surface observations of brittle features. Many of the other Fe-BMG variants, created to change the Po...

In this manuscript, we introduce  a new class of fuzzy problems, namely ``fuzzy inclusion linear systems" and   propose a fuzzy solution set for it. Then, we present a theoretical discussion about the relationship between  the fuzzy solution set of a  fuzzy inclusion linear system and the algebraic solution of a fuzzy linear system. New necessary and sufficient conditions are derived for obtain...

although uncommon, different kinds of foreign bodies, most of which metallic, have been reported to enter the appendix. the present report describes a case with a metallic foreign body-induced appendicitis, and makes suggestion in regards to the diagnosis and management of the problem. a metallic foreign body was accidentally observed in the right lower quadrant region in an abdominal x-ray tak...
