Tables Of Spectral Lines Of Neutral And Ionized Atoms by A. R. Striganov; N. S. Sventitskii

In this post, we will see the book Tables Of Spectral Lines Of Neutral And Ionized Atoms by A. R. Striganov; N. S. Sventitskii.

About the book

Born in the Kalinin region in 1907 and a graduate of Moscow State University, Prof. Striganov currently heads the Atomic Spectroscopy Laboratory at the I. V. Kurchatov Institute of Atomic Energy and is a member of the Committee on Spectroscopy of the Academy of Sciences of the USSR. His research focuses on methods of atomic emission spectrum analysis, optical spectra studies, hyperfine structure of heavy element spectra, and spectroscopic diagnosis of plasmas.

The original Russian text was published by Atomizdat in Moscow in 1966 and has been updated by the authors for this edition. Last-minute additions and corrections have been incorporated into the tables for convenience, prioritizing content over typographic aesthetics. The tables of Spectral Lines of Neutral and Ionized Atoms were first published in Moscow in 1966, and for this Plenum Press edition, corrections have been made, and additions based on journal articles have been included. Notably, additions have been made for spectra such as Li, C I, NI, N IV, and N V.

Previously neglected spectra, like those of N IV, N V, 0 IV, 0 V, and 0 VI, have now been studied more extensively in the laboratory. The American edition of the book incorporates precise values for these spectra, drawing from recent comprehensive papers refining the system of energy levels and expanding the classified lines in various regions of the spectrum. While retaining certain lines from earlier sources, the authors calculated wavelengths based on the refined energy levels. The book aims to provide useful data on the spectra of 22 elements for physicists and engineers.

బంగారు తాళం అనే బురతీనా సాహసకృత్యాలు (The Little Golden Key Or Adventures Of Bratino In Telugu ) by అలెక్సీ టాల్స్టాయ్ (A. Tolstoy)

In this post, we will see the book బంగారు తాళం అనే బురతీనా సాహసకృత్యాలు (The Little Golden Key Or Adventures Of Bratino In Telugu ) by అలెక్సీ టాల్స్టాయ్ (A. Tolstoy).


About the book

ముందుమాట

నేను చిన్న పిల్లాడిగా వున్నప్పుడు – యెప్పుడో, చాలా చాలా కాలంకితం – నా దగ్గర పినోచ్చియో లేదా చిన్న కొయ్య బొమ్మ” అనే పుస్తకం వుండేది. (ఇటాలియన్ భాషలో కొయ్య బొమ్మకి బురతీనొ అంటారు.)

బురతీనా సాహస కృత్యాల గురించి నేను నా స్నేహితులకి, మగపిల్లలకీ ఆడపిల్లలకీ, చెబుతూ వుండేవాణ్ణి. కాని ఆ పుస్తకం పోయింది. అంచేత ఆ పుస్తకంలో లేని రకరకాల సాహస కృత్యాలు చేర్చి కథని మార్చిమార్చి చెప్పేవాణ్ణి.

బాలలూ, యిప్పుడు యెన్నో యేళ్లు గడిచేయి. నా జ్ఞాపకాలు బురతీనా మీదకి మళ్లుతున్నాయి. అంచేత ఆ చిన్న కొయ్య బొమ్మ అతి సాహస కృత్యాల గురించి మీకు చెప్పాలని తీర్మానించుకున్నాను.

Foundations Of The Theory Of Plasticity by L. M. Kachanov

In this post, we will see the book Foundations Of The Theory Of Plasticity by L. M. Kachanov.


About the book

This book is based on lectures on the theory of plasticity delivered by the author at the Mechanics-Mathematics Faculty of the University of Leningrad. The author has not attempted to provide an exhaustive treatment of the entire theory of plasticity. The book primarily focuses on the plastic deformation of metals at normal temperatures, particularly in relation to questions of the strength of machines and structures. Its main objective is to offer a straightforward explanation of the fundamental equations of plasticity theory and the most well-developed methods for solving them, as well as to discuss issues characterizing the special nature of the plastic state and the variety of mechanical problems involved.

The second edition has undergone significant revisions to reflect important developments in the theory in recent years. More emphasis has been placed on yield surfaces and the associated yield law, and the chapters on plane stress and the axisymmetric problem have been expanded. The section on extremum principles and energetic methods of solution has been extensively rewritten. Additionally, a new chapter on the theory of shakedown, which is significant in understanding the role of varying loads in the onset of rupture, has been included. Progress in the model of a rigid-plastic body in dynamic problems over the last decade has led to some additions in Chapter XI.

To prevent the course from being overloaded with unnecessary details, some of the more difficult problems have been omitted from the second edition, and the chapters on the stability of equilibrium and composite plastic media have been abbreviated.

It is assumed that the reader is acquainted with the basic concepts of strength of materials and the theory of elasticity. To facilitate study, passages that may be omitted on first reading have been indicated in small type or marked with asterisks.

The list of references is not exhaustive. Special lists are provided to assist in navigating the extensive literature on the theory of plasticity, which includes books and review articles containing supplementary references.

The author acknowledges readers who pointed out defects in the first edition and expresses gratitude to A.A. Vakulenko, A.I. Kuznetsov, V.I. Rozenblyum, and G.S. Shapiro for their valuable comments on the manuscript. A.I. Kuznetsov also reviewed the proofs, and the author extends sincere thanks to him for a number of important corrections.

Translation from the second revised edition into English was provided by Multilingua Scientific Translations.

Brazing And Soldering Of Metals by N. F. Lashko; S. V. Lashko-Avakyan

In this post, we will see the book Brazing And Soldering Of Metals by N. F. Lashko; S. V. Lashko-Avakyan.

About the book

Soldering of metals and alloys, together with furnace welding, represents one of the oldest methods of securing a permanent joint between different parts. In order to distinguish fusion welding from other welding methods devised at the end of the last century, this method has been termed “soldering” by N.N. Benardos. Some basic principles of soldering laid down in ancient times and still applied today have proved to be insufficient for securing many kinds of permanent joints required for modern machinery building.

The intention of the authors of the present study has been to present known data on soldering processes in the light of their own experience as well as in the light of the general knowledge of the physical and chemical processes of soldering. The authors do not pretend to have given an exhaustive treatment of all the problems involved and admit that many of them still remain questionable.

The first section of the book deals with the distinguishing features of the design of soldered joints. Some problems concerning the interaction of liquid solders with the parts to be soldered, their crystallization, and internal structure of the soldered seam and its influence on the quality of the resulting connections are treated in the second section. Characteristic features of crystallization occurring in the soldered seam, as well as of the internal structure of the latter, have been published earlier in the authors’ study, “Physical Metallurgy of Welding”. In the third section, problems are examined connected with the selection of solders and fluxes required.

The fourth section deals with the basic methods of soldering, which are determined by the methods of heating the parts to be soldered and of removal of scale and oxide films, as well as by the methods of preparing solders. In the fifth and last section, essential features of soldering various alloys to different kinds of base metal are described.

Equazioni Della Fisica Matematica by A. N. Tichonov; A. A. Samarskij

In questo post vedremo il libro .


A proposito del libro

Le questioni della fisica matematica sono strettamente legate allo studio dei processi fisici più disparati nel cui novero rientrano fenomeni studiati in idrodinamica, teoria della elasticità, elettrodinamica ecc. I problemi matematici che sorgono in questo caso contengono numerosi elementi comuni e costituiscono l’oggetto della fisica matematica. Il metodo di indagine, che caratterizza questa branca scientifica, è sostanzialmente matematico. Tuttavia l’impostazione dei problemi della fisica matematica, strettamente connessa allo studio di problemi fisici, ha dei tratti specifici.

La cerchia di questioni inerenti alla fisica matematica è estremamente ampia. Nel presente volume sono trattati problemi di fisica matematica che conducono ad equazioni alle derivate parziali. Abbiamo cercato di subordinare la scelta e l’esposizione del materiale alle proprietà caratteristiche dei processi fisici tipici, per cui la disposizione del materiale corrisponde ai tipi fondamentali di equazioni.

Lo studio di ciascun tipo di equazioni inizia dai problemi fisici elementari che conducono alle equazioni del tipo considerato. Un’attenzione particolare viene prestata all’impostazione matematica dei problemi, all’esposizione rigorosa dei metodi di soluzione dei problemi elementari e all’interpretazione fisica dei risultati ottenuti. Ogni capitolo contiene problemi il cui scopo principale è quello di acquisire esperienza pratica. Alcuni problemi presentano di per sé interesse fisico rilevante. Alla fine di ciascun capitolo sono date appendici contenenti applicazioni dei metodi descritti nel testo alla soluzione dei problemi più disparati della fisica e della tecnica e una serie di esempi che escono dai limiti dei problemi trattati nel testo. La scelta di questi esempi potrebbe, ovviamente, essere diversa.

Il libro contiene soltanto parte del materiale trattato nel corso di metodi della fisica matematica, senza considerare la teoria delle equazioni integrali e i metodi variazionali. I metodi approssimati sono esposti in modo non sufficientemente completo. Il libro è basato su lezioni tenute per un decennio da A. N. Tichonov alla facoltà di fisica dell’Università di Mosca.
