Long-term emission sampling validation for PCDD/Fs control of compliance to permitted Emission Limit Values at a large sinter plant.

Continuous sampling of emission into air of dioxins has been one of the targets of Directive 2010/75/EU Of The European Parliament And Of The Council on industrial emissions (Integrated Pollution Prevention and Control, IED Directive) since year 2010. The present research was aimed at verifying the applicability of a long-term sampling system at the sinter plant of a large steel works in Taranto, Southern Italy, and to perform its validation compared to the standard reference method. Automated long-term samplings of 15 and 30 d were performed in parallel with manual short-term sampling, the latter with a frequency of two per week.

Inferomedial displacement of the meniscal free fragment: MR findings.

Purpose: To define the accuracy of Magnetic Resonance (MR) in the diagnosis of inferomedial displacement of the meniscal fragment.

Materials And Methods: The MR examinations of the knee performed between December 2002 and April 2004 on 676 patients (mean age 32 years) with knee trauma and subsequently subjected to arthroscopy were retrospectively reviewed to assess the presence of bucket-handle meniscal tear and inferomedial displacement of the meniscal free fragment. The MR examinations were performed using a superconductive 0.
