In this paper we will discuss the technical issues related to creating microbeams of heavy ions (e.g. iron) at energies higher than at existing microbeam facilities (up to 3 GeV/nucleon) and related to developing an electronic position sensitive detector for heavy ions with a position resolution better than 1 micrometer. The experimental requirements define microbeams to be beams which will hav...

Two hundred and one strains of Staphylococcus aureus isolated from in-patients and out-patients were examined for sensitivity to antibiotics, heavy-metal ions and ethidium bromide and for phage-typing pattern. Heavy-metal ion resistance was less frequent than reported in previous studies and was as frequent in penicillinase non-producing as producing strains. 'Methicillin-resistant' strains wer...

keep in mind the importance of cadmium, cobalt and nickel ions as environmentally and economically strategic heavy metals, the application of two acidic extractants, named bis(2-diethylhexyl)phosphoric acid (dehpa) and 2-thenoyltrifluoroacetone (htta), was assessed for the extraction-recovery of these ions from leached solution of spent rechargeable ni-cd batteries. the conditions for leaching ...

Introduction: Today, bottled waters have attracted the assurance of consumers as one of the important drinking water supply resources, such that in some regions, the use of bottled waters has replaced the drinking water distribution system. The present study was carried out with the aim of measuring and determining the heavy metals in bottled water across a number of brands produced in Iran and...
