Background: This paper presents a method to reduce radiation exposure during mammography by analysing the doses to ipsilateral and contralateral breasts and to adjacent organs by evaluating material-dependent shielding performance.  Materials and Methods: Six target-filter combinations (Mo-Mo, Mo-Rh, Rh-Rh, Rh-Mo, W-Mo, W-Rh) were tested by measuring the doses delivered to the breasts and adjac...

Cu(In,Ga)Se 2 (CIGSe) is a promising absorber material for thin‐film photovoltaic devices. A key procedure to achieve high efficiencies the application of alkali fluoride postdeposition treatments (PDT) CIGSe surface. While effects PDT on directly impacted front surface have been subject extensive studies, less known about impact deeply buried CIGSe/Mo interface. Exposing backside by stripping ...

Magnetic nanoparticles of iron oxide (Fe3O4 NPs) were prepared using a biosynthetic method to investigate their potential use as an adsorbent for adsorption Pb(II) and Cd(II) from the aqueous solution. The present study first time used magnetite leaf extract Portulaca oleracea removal metal ions. Characterizations Fe3O4 NPs (PO-Fe3O4MNPs) achieved by X-ray diffraction (XRD), field emission scan...

the electrocatalytic degradation of methyl orange (mo) on pbo2-tio2 nanocomposite electrodes was studied by cyclic voltammetry and bulk electrolysis. the results reveal that pbo2-tio2 nanocomposite electrodes possess higher oxygen evolution overpotential than pbo2 electrodes and the electrocatalytic degradation of mo on the electrodes is direct oxidation process. the influence of experimental p...

The bacterial flagellum is a motility organelle that consists of a rotary motor and a helical propeller. The flagella usually work individually or by forming a loose bundle to produce thrust. However, the flagellar apparatus of marine bacterium MO-1 is a tight bundle of seven flagellar filaments enveloped in a sheath, and it has been a mystery as to how the flagella rotate smoothly in coordinat...

The asymmetric unit of the title compound, [Mo(C(19)H(16)Cl(4)N(2)O(2))O(2)], comprises two independent mol-ecules (A and B). The geometry around the Mo(VI) atom is distorted octa-hedral in each complex mol-ecule, supported by two oxide O atoms and the N(2)O(2) donor atoms of the coordinating ligand. The dihedral angle between the benzene rings is 74.96 (11) Å for mol-ecule A and 76.05 (11) Å f...

Effects of fifteen particulate objects, fourteen metals and one non-metal on cell viability of osteoblast-like cells were studied in vitro, to determine whether an adverse effect on cells could be induced by the particulate ferm or soluble ions. The Al, Ti, Zr, Nb, Ta, Cr, Mo, and Fe particulates depressed cell viability at higher particulate concentrations, but their extracts yielded no effect...

Metal-on-metal (MoM) bearings have become popular due to a major advantage over metal-on-polymer bearings for total hip arthroplasty in that the larger femoral head and hydrodynamic lubrication of the former reduce the rate of wear. However, concerns remain regarding adverse reactions to metal debris including metallosis caused by metal wear generated at the taper-head interface and another mod...

The macrophage mannose receptor (MR) is a pattern recognition receptor of the innate immune system that binds to microbial structures bearing mannose, fucose and N-acetylglucosamine on their surface. Trypanosoma cruzi antigen cruzipain (Cz) is found in the different developmental forms of the parasite. This glycoprotein has a highly mannosylated C-terminal domain that participates in the host-a...
