Book excerpt: Many books cover the determination of rate constants under different experimental conditions and different chemical composition of the reaction mixture in their formal treatment of thermal kinetics. However, most textbooks are limited to simple mechanisms. In contrast, analogous treatment of photochemical reactions is limited to the publication of special reactions and investigations. Therefore, this book is aimed at providing an overall description of formal photokinetics covering a wider scope than the usual books on kinetics. This volume attempts to provide a concise treatment of both thermo- and photochemical reactions by means of generalised differential equations, their set-up in matrix notation, and their solution by a formalism using numerical integration. At a first glance this approach might be surprising. However, apart from the argument that the didactics of thermal reactions are easier to handle than those of kinetics, the book provides additional reasons in support of this approach. Therefore, the formalism derived allows the evaluation of photochemical reactions, which are superimposed thermal reactions taking into account that the amount of light absorbed varies during the reaction. Because of this, any approximation, either by using total absorbance or negligible absorbance, will cause considerable errors even for simple reactions. The approach chosen to transform the axis of the radiation time into a new variable that includes the photokinetic factor proves that formal kinetics can be applied to thermal and photochemical reactions as well, and even allows the handling of solutions that cannot be homogenised or solid samples in which the concentration varies locally. By using this approach to introduce partial photochemical quantum yields even complex mechanisms can be determined quantitatively. A large number of examples for different mechanisms and an introduction to many spectroscopic and chromatographic methods suitable for photokinetic analyses are provided to enable the reader to carry out a step-by-step evaluation of his own measurements. To reduce the number of formula in some chapters an appendix has been included which contains a detailed description of the calculus of some essential examples. For the convenience of the reader the following has been included: • A large number of examples describing the use of formula • A detailed description of the procedure for applying photokinetics to complex consecutive photoreactions • An Internet address where the reader can find a tutorial for this procedure:http://www.barolo.ipc.uni-tuebingen.de/tele/photokin/ • A simple macro to help in programming his own evaluation procedure.

Book excerpt: Recently there have been major developments in the experimental techniques available for the study of the primary events following the absorption of ultra-violet and visible radiation by biological systems. These techniques, which include absorption, emission, resonance Raman, electron spin resonance, nuclear magnetic resonance and photoacoustic spectroscopies, can be used to study the fate of transient species with lifetimes ranging from seconds to nanoseconds and extending in some cases, such as laser flash photolysis, to pico 12 15 (10- S)- and even femtoseconds (10- s). In parallel with these developments there has been a dramatic increase in the use of light in medicine via the direct photochemical alteration of endogenous molecules (phototherapy) or via the photoactivation of drugs in the skin or other tissue (photochemotherapy). Thus neonatal hyperbili rubinaemia can be routinely treated by phototherapy and psoriasis is frequently treated by PUVA photochemotherapy. A promising new photo chemotherapy used the phototoxicity of porphyrin drugs activated by red light to destroy solid malignant tumors. While some of the overall qualitative effects of such treatments are known, only recently have we begun to understand the associated molecular mechanisms. The primary molecular processes involve short-lived species. The pur pose of this Advanced Study Institute was to review some newer experi mental techniques for the study of such species, the application of these techniques to biological and medical systems and to examine the value of such information in phototherapeutic situations.

Available in PDF, EPUB and Kindle. Book excerpt: This unabridged work includes a previously distributed DICTIONARY OF LATVIAN PROVERBS, making it unique and more attractive than similar publications. A translating dictionary, like this one, is a practical dictionary that translates words in existing texts. It does not, as a rule, provide descriptions or explanations, nor does it set norms of how words should be spelled. The aim of dictionary users can be either to understand the source language (the language of the headwords) or to translate it into the target language(the language of the translation equivalents). The user’s first language can be either the source language or the target language. This makes for four possible types of interlingual dictionaries (descriptive, prescriptive, or translating). Existing Latvian-English dictionaries indicate that they are intended for users whose first language is Latvian and whose purpose is to translate it into English. This dictionary is intended primarily for users whose first language is English and who wish to understand texts written in Latvian. This, of course, does not preclude Latvian speakers from using it to translate from Latvian into English, i.e., to produce English texts. English-speaking Latvians may, in fact, find it helpful for accurate and natural translation. Other features of this dictionary are: the number of entries(over 106,000), which is more than double that of any other Latvian-English dictionary; the use of American rather than British English; an extensive coverage of technical terms from all fields of science and technology; the comprehensive inclusion of spelling variants; and the inclusion of colloquialisms, common speech words, vulgar terms, slang, barbarisms, selected regionalisms and terms found in folkloric language. The entries of this dictionary were collected from various extant monolingual and bilingual Latvian dictionaries, general and specialized: spelling dictionaries, technical dictionaries, etymological dictionaries, general encyclopedias, periodical literature, and many Latvian speakers. Of the latter, I want to single out the contribution of the late sea captain, Inats Lejnieks. In his time, the captain had commanded full-rigged sailing ships with Latvian crews, and he supplied the Latvian equivalents of the names of sails and principal ropes, spars, and part of the hull. I was fortunate to have captain Lejnieks share his expertise with me as this material was not available anywhere else.
