This step-by-step Pocket Guide will teach you how to draw stunningly beautiful perspectives, complete with reflections and shadows. The Pocket Guide to Perspective uses a simple, step-by-step method to help readers understand the basic concepts of perspective construction. Readers will learn to build one-point, two-point, and multi-point perspectives as well as reflections and shadows in perspective. This small pocket guide is compact and focused. Whether you’re at your desk or out and about, it is useful reference to bring along for both students and professionals alike.

This volume collects the papers presented at the "Specialists' Meeting on Nuclear Level Densities", held in Bologna 15 - 17 November, 1989, which gathered most of the scientists working in the field. The papers cover all the major aspects of the level density problem both from the theoretical and the experimental viewpoint, including the subject of partial level densities. In particular, moment method, collective vector method, interacting boson model, static path approximation and combinatorial approach are discussed. Effects of the residual interactions and nuclear structure are also addressed, giving a state-of-art reveiw of our present knowledge on nuclear level densities.
