a 48 year old patient was candidate for anterior mandibular reconstruction by 2 fixtures of branemark implant. residual infection lead to removal of one of the implants from the extracted tooth socket. afterwards, 2 fixtures of bonefit was inserted adjacent to previously placed branemark implants and final prosthesis were loaded in a joint cemented and screwed design.

Background: Phenol as an aromatic hydroxyl compound are considered as a priority pollutant.  Because of their stability, solubility in water and high toxicity had health important. Methods: In the present experimental study, electrocoagulation reactor by iron electrodes are used in the presence of hydrogen peroxide to phenol removing from aqueous solutions. Effects of variables including ...

Abatement: A measure or set of measures designed to permanently eliminate lead-based paint hazards or lead-based paint. Abatement strategies include the removal of lead-based paint, enclosure, encapsulation, replacement of building components coated with lead-based paint, removal of lead-contaminated dust, and removal of lead-contaminated soil or overlaying of soil with a durable covering such ...

batch experiments were conducted to study the adsorption behaviors of lead ion (pb2+) onto ferrihydrites prepared using three different procedures which were characterized  by textural analysis (bet). the adsorption removal of pb2+ by the three ferrihydrites (called fh-1, fh-2 and fh-3, respectively) were compared, and fh-3 shows fast adsorption kinetics as well as high adsorption capacities, t...

the expensive nature of metal ions detoxification from wastewater have restricted the use of conventional treatment technologies. cheap, alternative measures have been adopted to eliminate metal contamination, and adsorptions using agricultural adsorbents seem to be the way forward. the use of agricultural adsorbents for cadmium (ii), copper (ii) and lead (ii) ion removal has gained more intere...
