Non-invasive Investigations of Paintings by Portable Instrumentation: The MOLAB Experience.

The in situ non invasive methods have experienced a significant development in the last decade because they meet specific needs of analytical chemistry in the field of cultural heritage where  artworks are rarely moved from their locations, sampling is rarely permitted, and analytes are a wide range of inorganic, organic and organometallic substances in complex and precious matrices. MOLAB, a unique collection of integrated mobile instruments, has greatly contributed to demonstrate that it is now possible to obtain satisfactory results in the study of a variety of heritage objects without sampling or moving them to a laboratory. The current chapter describes an account of these results with particular attention to ancient, modern, and contemporary paintings. Several non-invasive methods by portable equipment, including XRF, mid- and near-FTIR, UV-Vis and Raman spectroscopy, as well as XRD, are discussed in detail along with their impact on our understanding of painting materials and execution techniques. Examples of successful applications are given, both for point analyses and hyperspectral imaging approaches. Lines for future perspectives are finally drawn.

The unification model: a collaborative effort.

The Rush unification model unites clinical practice with nursing education. In this system, nursing faculty possess joint responsibilities to the college of nursing and to a specific unit in the medical center. Collaboration among managers, clinical specialists, educators, and researchers leads to achievement of unit, college, and departmental goals. The collaborative process among the leadership group members in the medical intensive care unit, consisting of the unit leader, the assistant unit leader, the clinical nurse specialists, and the practitioner-teachers, is described in detail to show how utilization of the skills and strengths of each team member increases the benefits to the unit and the patient.
