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...

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...

nanoparticles classified in 4 overall groups containing: metallic nanoparticles, ceramic nanoparticles, polymeric nanoparticles and semiconductor nanoparticles. these nanoparticles are used in some biomedical applications such as carrying medicine and photographing agents. with attention to different criteria which are both qualitative and quantitative, selecting the most suitable nanoparticles...

Le secteur de Kadruka, en Nubie soudanaise, recèle près deux douzaines cimetières néolithiques, datés du Ve millénaire av. J.-C. L’exploration cours site KDK 23 a d’ores et déjà livré plus 130 sépultures, individuelles hors doubles. Parmi le matériel souvent abondant associé aux défunts, neuf voire élaboré pour les funérailles, vases céramique tiennent une place singulière. Objets issus quotidi...
