Instant Light

A volume of sixty Polaroid photographs of the late Russian filmmaker's friends and family consists of images taken between 1979 and 1984 in his native land and Italy, where he spent time in political exile. Original.

The existence and competition of trees and shrubs to sustain and put forth growth under varied environmental conditions is dependent on the interactions that occur between the plant metabolic processes and the prevailing environmental conditions. In order to understand the productivity of trees and shrubs, it is a prerequisite to know the experimental techniques of these vital processes. This volume provides a comprehensive presentation of this topic. The first part of this book deals with various aspects of experimental ecophysiology and recent research results of studies on plant pigments, epicuticular wax, leaf nutrients, carbon fixation, all supported by literature. The second part of the volume describes various laboratory techniques such as diffusion, imbibition, calorimetry, atomic absorption, mineral nutrition, nutrition analysis of forage, litterfall chemistry, nutrient cycle, etc. The third and fourth parts deal with advances in the techniques in the development of ecophysiology. The book will serve as an important handbook and resource for students, faculty and teachers, technicians, and researchers and scientists involved in forest science dealing with ecophysiology and biochemistry of woody and crop plants.

This book is a comprehensive guide to the theory and practice of lighting. Covering the physics of light production, light sources, circuits and a wide variety of lighting applications, it is both suitable as a detailed textbook and as thoroughly practical guide for practising lighting engineers. This fourth edition of Lamps and Lighting has been completely updated with new chapters on the latest lamp technology and applications. The editors ahve called upon a wide range of expertise and as a result many sections have been broadened to include both European and US practice. The book begins with a description of the fundamentals of light, vision, colour and measurement. Part II, the main section of the book, deals with lamps and control equipment and includes descriptions of all lamp types in use today. Part III on lighting covers both interior and exterior applications.

This book goes right to the heart of what every professional and student needs to know above all - how to effectively meet real-world lighting design challenges.

The technique of chlorophyll fluorescence has a relatively short history, beginning with the observations by Kautsky (Kautsky and Hirsch, 1931). Since that time there have been several· reviews devoted to the subject, with most of them highly theoretical (Bohlar-Nordenkampf and Oquist, 1993; Dau, 1994; Schreiber et aI. , 1994). There have also been many books devoted to generalized spectrophotometric and microscopic fluorescence techniques. However, to the best of our knowledge there has not been a book completely devoted to the practical applications and uses of chlorophyll fluorescence in plant biology. As techniques mature, applications multiply and so do their potential advantages. The chlorophyll fluorescence technique is maturing as can be seen in the increasing numbers of publications that are devoted to its use. Therefore, we considered that now was a good time to compile the existing knowledge for the applied use of this technique and provide a single volume to which a novice or experienced user could refer. Highly trained experts in the field of photobiology have primarily used the chlorophyll fluorescence technique in the past. In that work, understanding the mechanisms and controls of the photosynthetic processes was the main focus of activity and discussion. Much of the equipment used was highly specialized and expensive, or in some cases one-of-a-kind lab designed units. However, the development of several reliable commercially available chlorophyll fluorescence monitoring instruments has changed the potential user base for the technique.

The four-volume set LNCS 14442 -14445 constitutes the proceedings of the 19th IFIP TC 13 International Conference on Human-Computer Interaction, INTERACT 2023, held in York, UK, in August/September 2023.
