    Spatial Vectorcardiography presents a review of two kinds of vectorcardiograms: axonocardiograms and stereo cardiograms. All the vectorcardiograms are provided and have to be confronted with the respective electrocardiograms, which should be considered as the code for estimating the significance of the spatial presentation. The text is organized into two parts. Part I begins with some general remarks on spatial vectorcardiography. This is followed by discussions of vectorcardiographs devices (axonocardiograph and stereocardiograph); graphical representation of axonocardiograms and stereocardiograms; and arrangement of plates. Part II presents a collection of axonocardiograms, stereocardiograms, and electrocardiograms. The material of this book was contributed by the Department of General and Experimental Pathology and the Cardiological Centre at the Clinical Hospital No. 1, by the II Clinic of Surgery, III Clinic of Internal Diseases and II Clinic of Pediatrics, Medical School in Wroclaw, by the I Clinic of Internal Diseases, Medical School in Wroclaw, by the I Clinic of Internal Diseases, Medical School in Cracow, and by the III Clinic of Internal Diseases, Silesian Medical School in Bytom.

    Modern Russian Stress is a translation from the Russian dealing with pronunciation of Russian words. This guide to pronunciation, particularly on the correct stress given to the modern spoken Russian word, covers the laws of orthoepy. Orthoepy concerns the principles ensuring the unity of sounds that are recognizable in a particular language. This book analyzes stress in the spoken word in terms of either the sense-group or the breath group. The speaker uses specific intonation and pauses which make the words recognizable. Stress is a word indicator. This guide explains the different ways of stressing a word-syllable, such as the dynamic stress, musical stress, and quantitative stress. This book gives additional attention to the fixed and free stresses. In the Russian language, stress has no fixed position and can occur at any syllable or morphological element of the word, or can shift positions depending on the word use. This book also explains the sound structure and form of certain words. It analyzes stress when found in nouns, verbs, participles, and adjectives, and weak or unstressed words when located in prepositions, conjunctions, pronouns, numerals, linking-verbs, modal verbs and parenthetic verbs. An important part of this guide is the glossary that includes several thousands of Russian words that are usually mis-stressed. This guide can be useful to the student learning elementary Russian, and for migrants and overseas workers who know a little Russian.

    • English
    Chronic Radiation Hazards: An Experimental Study with Fast Neutrons describes a large-scale experiment on the hazards to be expected from low and very low levels of chronic irradiation by fast neutrons. Fast neutrons may be an environmental hazard around nuclear reactors and some machines for accelerating particles, and it is therefore of practical as well as academic importance to get some idea of the likely ill-effects of chronic irradiation by fast neutrons. The book is organized into four parts. Part I describes the experimental design, including factors such choice of animal, choice of dose rate, observation of radiation effects, dose measurements, and energy of the neutrons. Part II deals with the measurement of fast neutron dose. Topics discussed include Interaction of neutrons with light elements; energy absorption due to fast neutrons; energy absorption due to gamma rays; and ionization-dose and ionization-flux relations for fast neutrons. Part III discusses the results of fast neutron irradiation while Part IV covers the relative biological efficiency of fast neutrons and gamma rays for chronic exposures.
