Evaluation of the Photocatalytic Activity of a Cordierite-Honeycomb-Supported TiO Film with a Liquid-Solid Photoreactor.

Anatase nanoparticles in suspension have demonstrated high photoactivity that can be exploited for pollutant removal in water phases. The main drawback of this system is the difficulty of recovering (and eventually reusing) the nanoparticles after their use, and the possible interference of inorganic salts (e.g.

[Algorithms for the evaluation of chemical risk: the Piedmont Region's experience].

The programme InfoRisk, proposed by the Piedmont Region in 2002, has been an important reference point for the evaluation of chemical risk, both for companies and the regional prevention system alike. Nowadays, it is still considered necessary to take advantage of simple methods for the evaluation of this risk. However, the Piedmontese model requires some modification so as to keep it in line with the national and international rules and regulations governing the question and to find some solutions to problems that have arisen in its practical application.

CT findings in primary pulmonary lymphomas.

Purpose: To describe the CT findings of pathologically confirmed primary pulmonary lymphomas.

Materials And Methods: The CT examinations of 11 patients with pathologically proven primary pulmonary lymphoma (9 BALT lymphomas and 2 non-BALT lymphomas) were retrospectively reviewed by three radiologists. Evaluated findings included morphology (consolidation, mass, nodule), number and distribution of lesions.

Low dose CT in early lung cancer diagnosis: Prevalence data.

Purpose: Lung cancer has a high mortality rate and its prognosis largely depends on early detection. We report the prevalence data of the study on early detection of lung cancer with low-dose spiral CT underway at our hospital.

Materials And Methods: Since the beginning of 2001, 519 asymptomatic volunteers have undergone annual blood tests, sputum tests, urinalyses and low-dose spiral CT.
