Quality and content of internet-based information on temporomandibular disorders.

Aims: To use a range of evaluation instruments to assess the content and quality of websites about temporomandibular disorders (TMD) and thereby provide guidance regarding the actual accuracy and comprehensiveness of the information of the sites.

Methods: Sixty-seven websites resulting from an Internet search with the word "TMD" were evaluated using Journal of the American Medical Association (JAMA), DISCERN, and Health on the Net (HON) criteria, along with an evaluation method to assess the scientific quality of the website contents. Results were compared according to reviewer, website type, and presence of HON seal.

Application of a peroxymonosulfate/cobalt (PMS/Co(II)) system to treat diesel-contaminated soil.

We investigated the feasibility of using peroxymonosulfate (PMS) with transition metals (PMS/M(+) system) for remediation of diesel-contaminated soils. To the best of our knowledge, this is the first attempt to apply a PMS/M(+) system for the treatment of diesel-contaminated soils. Two well-known transition metals, Fe(II) and Co(II), used to activate PMS including the effect of co-existence of counter anions (Cl(-) and SO(4)(2-)) were tested and it revealed that the most effective degradation of diesel was achieved with cobalt chloride.
