How to Write a Dissertation or Thesis

From my Academic Writing Archives...

HOW TO WRITE A DISSERTATION
Simple Tips
By
VIKRAM KARVE

Art of Dissertation 
– Part 1

THESIS STATEMENT

I wrote a dissertation to earn my Masters Degree in Technology (M.Tech.) from IIT Delhi (1981-1983) 
– and one more – for my Post Graduation in Management in 1985. 

Of course – in my earlier days – I wrote a few seminar and project reports during my B. Tech. degree studies (1972-1977). 

Since then 
– I have supervised and guided dissertations – more than 45 – maybe 50 – chiefly for Masters Degrees in Engineering and Technology (ME / M. Tech.) – and also in Management Studies. 

Some students of mine thought it apt than I pen down a few tips on the art of dissertation 
– so here are I am – writing a few lines – on The Art of Dissertation.

In a nutshell 
– the Art of Dissertation comprises the following simple steps:

1. Select a dissertation topic in a subject that you are knowledgeable about.

2. Compose a thesis statement that only asks a single question.

3. Employ a research methodology process that is compatible with your dissertation study.

4. Present your data evaluation, analysis and interpretation in an accurate, succinct, logical, well-reasoned and lucid manner and write your dissertation report in a simple, coherent manner conforming to the prescribed style.

5. Conclude your dissertation by answering the thesis statement and, if pertinent, mention corollaries and consequences and possibilities and scope for future research work on the subject.

6. Impart the finishing touches to your dissertation report – definitions, references, bibliography, abstract, summary, acknowledgement, certificate, contents and title pages.

WHAT IS A DISSERTATION...?

A Thesis is a hypothesis or conjecture. 


The word "thesis" is coined from the Greek derivative of the word meaning "position", and refers to an intellectual proposition. 

A thesis may be an unproved statement, a hypothetical proposition, put forward as a premise.

A Dissertation is a lengthy, formal document that argues in defence of a particular Thesis. 

The term "Dissertation" is derived from the Latin word dissertātiō 
– meaning "discourse" – and is a document that presents the author's research and findings and, in most cases, is submitted in support of candidature for a degree or professional qualification. 

The research performed to support a thesis must be original and substantial. 

The dissertation must illustrate this aspect and highlight original contributions.

Your dissertation is your research which demonstrates your understanding of the subject in a clear manner. 


Therefore, it is imperative you find a topic that gives a clear picture of what you should write. 

Always ignore ambiguous and vague ideas. 

And, most importantly, choose an apt title – in fact, the title of your dissertation must fascinate you and entice your audience.
CHOOSE THE TYPE OF YOUR DISSERTATION

Dissertations are of two types – Empirical and Analytical.

Empirical Dissertations make propositions resulting from experiments, involving laboratory or field research.

Analytical Dissertations reflect propositions resulting from meticulous, pioneering and innovative analysis of previously published work.

WRITING YOUR DISSERTATION REPORT

A dissertation report may comprise the following main chapters:

1. Introduction- An overview of the problem; why it is important; a summary of extant work and, most important, the thesis statement.

2. Literature Review-the chapter that summarizes another work related to your topic.

3. Methodology-the part of the paper that introduces the procedures utilized for the research study and the conceptual model.

4. Data Presentation, Evaluation, Analysis and Interpretation -the chapter involves the presentation of computation values using statistical tools to support the claim.

5. Conclusion-the complete summary of the research findings.

Of course, you must include suitable pages for definitions, illustrations and graphs, footnotes and references, bibliography, abstract, summary, acknowledgement, certificates, contents and title pages.

Introduction

Dissertation writing chiefly involves the introduction, literature review, methodology and analysis chapters, and the others mentioned above. 


Having selected your dissertation topic, before you begin your dissertation you need to establish your thesis statement first. 


Thesis Statement

A thesis statement is simply a single sentence that provides the main intention of the research. 


The thesis statement will epitomize the scope of your study, give you an idea of what you want to prove and will pilot your research.

A good Thesis Statement must satisfy the following four criteria:

1. The thesis statement must state your position.

2. The thesis statement must be able to support a discussion.

3. The thesis statement must be specific about its position.

4. The thesis statement should only have one single idea of discussion.

You must ponder over the following points while writing the introduction to your dissertation:

Is there any need to this dissertation study...?

Why do it now...? 


Why do it here...? 

Why me...?

Is the dissertation topic in my “comfort zone” 
– and am I thirsty for knowledge and passionate about it...?

Is there a problem...? 


What is it...? 

Why does it need to be solved...? 

Should I approach it empirically or analytically...?

What is my hypothesis...? 


Is it original, novel, new, innovative...?

Who will benefit from my dissertation work...? 


In what sense will they benefit...?

How will my contribution add to “commons”...?

What is going to be my methodology...? 

[modalities of data collection, evaluation, analysis, interpretation]

Are there any constraints or limitations in conduct of my proposed dissertation studies and research...?

Art of Dissertation – Part 2

REFERENCE CITATIONS

Whenever you use any words, ideas or information from any source in your dissertation, you must cite and reference those sources to acknowledge the contributions of others in your dissertation work.

Citations

Reference Citations may be included in the following forms:

1. Footnote Referencing in the text at the foot or bottom of the page.
2. Endnote Referencing or Citation-Sequence System collated and listed chronologically at the end of the text.
3. Bibliography

Citations serve inter alia the following purposes:

Establish credibility of the research.

Enable assessment of the quality and timeliness of the research.
Acknowledge the contributions of others and sources of information in your dissertation work.
Provide identification of material used in your research or quoted in your dissertation report.
Facilitate inclusion of material of supplemental value.
Intellectual Honesty.


REFERENCING [Footnotes and Endnotes]

In your dissertation you can do referencing using either Footnotes or Endnotes.

A Footnote is a bottom-of-the-page citation 
– whereas Endnotes are collected at the either at the end of the dissertation or at the end of each chapter.

Footnotes and Endnotes serve the same purpose. 


However, they are two different systems, so be consistent and use one of the two methods throughout your dissertation.

The advantage of footnoting is that readers can simply cast their eyes down the page to discover the source of a reference which interests them 
– but now-a-days Endnotes [References] at the end of the dissertation seem to be preferred.

References are to be sequentially numbered throughout your dissertation starting with 1, indicating the relevant number [note identifier] at the end of the pertinent sentence in the text, superscripted, or in brackets, and amplified by the citation either at the bottom of the page [footnote] or at the end of the dissertation [endnote]. 


The citation should provide the following bibliographic information:

1. Author(s) surname(s), first name(s) or initials
2. Name of the article, book or journal
3. Editors (if applicable)
4. Publishers Name and Location
5. Volume and Issue Number or month of publication (in case of a journal)
6. Year published
7. ISBN (if applicable)
8. The exact page numbers if your reference is a direct quotation, a paraphrase, an idea, or is otherwise directly drawn from the source. [p – page, pp – pages]

Titles of publications should be italicised, article titles should be enclosed between single quotation marks, and commas must be used to separate each item of the citation and end with a full stop.

Examples:

Book

1. Wilson B, ‘Systems, Concepts, Methodologies and Applications’, John Wiley and Sons, USA, 1984, p 29

Journal [article]

2. Steiner CJ, ‘Educating for Innovation and Management’, IEEE Transactions on Education, Vol 41, No. 1, Feb 1998, pp 1-7

Conference Proceedings [paper]

3. Sriram S and Karve VW, ‘Systems Cybernetic Re-engineering for Empowering Human Performance: A Soft Systems Dynamics Approach’, Proceedings of the International Conference on Cognitive Systems, Dec 1998, pp 723 – 739.

Internet Citations must include:

1. Name(s) of Author (s) / Editor (s)
2. "Title of Article, Web page or site" in quotation marks.
3. Name of sponsor of site or Title of Journal
4. Date of article, of Web page or site creation and latest update.
5. Access date (the date you accessed the Web page or site).
6. Complete Uniform Resource Locator (URL) in angle brackets.

Example:

Karve VW, ‘Ethics, Values and Technology’, in Cognitive Systems Review, July 2008, viewed on 21 August 2008 < Academic and Creative Writing Journal Vikram Karve >

Some Abbreviations in Referencing

ibid is used in consecutive references that refer to the same work, whether to the same or different pages.

Example: [the digits 1,2,3 are the footnote or reference numbers]

1. Karve V, ‘Appetite For A Stroll’, Cinnamon Teal, India, 2008, ISBN 9788190690096, p 15.

2. ibid [Please note that this refers only to page 15 of the above book and not to any other page of that book]

3. ibid, pp 29-34. [This still refers to Karve, but to pages 29-34]

op. cit. is used with non-consecutive references that refer to the same work but to different pages.

loc. cit is used with non-consecutive references that refer to the same work and to the same page or pages of that work.

Examples of Referencing
(the digits 4, 5, 6, 7, 8, 9 are footnote or reference numbers)

4. Senge P, ‘The Fifth Discipline’, Currency Doubleday, USA, pp 75-76.

5. Twiss BC, ‘Managing Technological Innovation’, Longman, UK, 1974, p 33

6. Senge, op. cit., pp 101-110 [Note that the footnote reference numbers to Senge are not consecutive and that different pages in his work are being cited].

7. Karve V, op. cit., pp 117-120. [Different pages of Karve (reference at serial 1 above) are being cited]

8. ibid [This refers to Karve, pp 117-120]

9. Twiss, loc.cit. [The reference is to Twiss page 33. Citation of any other page or pages would have entailed the use of op. cit, followed by the page number(s)]

When references are made to two or more books or papers of the same author, the abbreviations op.cit. and loc. cit. are not used in subsequent citations, in order to obviate confusion.

In referring to material contained in other pages of your own dissertation you may use the following abbreviations followed by the appropriate page number:

cf (confer) – compare
cf, ante (confer ante) – compare above
cf, post (confer post) – compare below
supra (above) – cross-reference to preceding matter
infra (below) – cross-reference to succeeding matter
et passim (and here and there) – matter referred is scattered in the dissertation.

Bibliography

A bibliography should generally contain all the sources cited in the dissertation and any other important references [books, journals and internet websites] that you have consulted during your research or used in preparing your dissertation.

Systematically list the various sources of information consulted or used in your dissertation [books, journals, internet websites, previous research work / dissertations] separately in alphabetical order of authors’ surnames in the same style as references.

The distinction between references and bibliography is that whereas references [footnotes and endnotes] cite authority for specific statements, the bibliography gives descriptions of entire works.

If a reader wants to consult a work referred to in a footnote, he/she turns to the bibliography for a full description of that work.

To end this article on a lighter note – let us have a quote:

PUNE Queen of the Deccan (An Attractive and Informative Book on Pune) - Book Review

Here is a Book Review I had written long back on a lovely book on Pune, once more, for you to read:

PUNE - Queen of the Deccan

(An Attractive and Informative Book on Pune)

Book Review
By
VIKRAM KARVE


Details of the Book:

Title: PUNE Queen of the Deccan
Authors: Jaymala Diddee & Samita Gupta 
Photographs: Sandesh Bhandare
Revised edition: 2013 
Published  by INTACH Pune Chapter
ISBN 81-901796-5-9
 
Book Review by Vikram Karve 

Pune is my hometown. 

I have lived in the heart of Pune, for most of my life, with intermittent breaks, on and off, ever since I was a small boy. 

I have read many books on Pune, and its history, in Marathi and in English.

But this book is the first definitive reference book on Pune I came across, and so, I have decided to tell you a little about it.
 
“PUNE Queen of the Deccan” is a superb book, very appealing at first sight, owing to its excellent get up and superior production values. 

The generous support given by Pune’s corporate sector is evident in the impressive quality of the book which at first glance attracts you to pick it up, enchants you as you browse and impels you to read it thoroughly.  

The authors say in the preface that writing this book was a journey of discovery for them.

Reading this delightful book was a journey of discovery for me too.

And so will it be for readers, especially for true blue Punekars, and also for the recent entrants to this glorious city, for whom this is must-reading in order to familiarize themselves with glorious history, culture and traditions of their new home.
 
This is no coffee table book, but a well-researched treatise, a significant piece of academic work, adorned with rare photographs, embellished with explanatory maps and informative sketches, written in easy readable style. 

While delving way back briefly into the hoary past, the authors comprehensively record the growth of Pune [earlier known as Poona ] over the last three and a half centuries.
 
Starting from ancient days, the authors chronologically trace the salient periods and cardinal events in the history of Pune. 

In engrossing storytelling style, the book enlightens the reader about the changing faces and fortunes, the ups and downs, the shifting geographical, spatial, architectural, military, economical, industrial, organizational, governmental, academic, cultural and demographical transformations of Pune, from a medieval town of indigenous origin to the chaotic metropolis of today.
 
The rare photographs and vivid maps enhance the value and joy of the fascinating journey through time. 

The quintessence of Pune, the “Peths”, their genesis and development, are covered in great detail, with which all Punekars identify even today. 

Read the book, acquaint yourself with Pune’s military legacy and history, its battles and trials and tribulations, like the plundering and ravaging by conquerors, the terrible pestilent plague epidemic, the devastating floods of 1961 when the Panshet dam burst, the modernization and development through the ages, study the maps, have a look at the photographs, observe the architecture of the wadas, the temples, and take a walk through the heart of Pune, and see for yourself how his enhances your understanding of Pune’s rich heritage and legacy. 
 
The advent of the British led to the establishment of Poona Camp, the cantonment. 

This resulted in a geographical and cultural divide, and someone wrote: “…There are Poonas almost as far removed from each other as the North and South poles”. 

This divide was evident till recently, certainly in the nineteen sixties (1960s), when I was a small boy living in Sadashiv Peth.

But now everything has changed, and barring a few remnants of the glorious past, when Pune had such sobriquets like “Pensioners’ Paradise”, “Oxford of the East”, “Queen of the Deccan”, in contrast, today the entire Pune is one huge unplanned overcrowded polluted urban conglomeration and concrete jungle, with chaotic traffic, getting worse day by day, its infrastructure unable to keep pace with the rapid expansion. 

Have a look at the photographs of Main Street, East Street and Poona Camp [pp 156 – 165], Poona Railway Station [pp 177- 178], Mandai [p 188], Ganeshkhind Avenue[p203], the Peths[208] and the maps on p64, p172, p176, p258 and p262 and you will see what I mean.
 
I wish the authors had also written a chapter on the culinary history of Pune, telling us a bit about the traditional foods that evolved in the Maharashtrian city; the advent, and symbiosis and nurturing of Mughlai, Deccani, Irani, Parsi and other delightful cuisines, and about the famous landmark eateries in Pune City and Camp, many of which are disappearing day by day, unable to withstand the onslaught of “liberalisation”. 

I do feel that the evolution of cuisine is a very important aspect of the history and culture of a city and Pune certainly has a delicious repertoire of a variety of unique and exciting foods.
 
I thoroughly enjoyed reading this engrossing and educative book. 

The first-rate design, attention to detail, attractive illustrations and engaging writing style ensure a compelling and delightful reading experience.

At times, it is unputdownable.   
 
I earnestly commend this book. 

I am glad I read it. 

The authors, photographer, collators, designers, editors, and all those who contributed to, and were involved in, the production of this masterpiece deserve congratulations for their creativity and praiseworthy efforts.

“PUNE Queen of the Deccan” is must-reading for all true blue Punekars, students of humanities and architecture, and new entrants to Pune, especially the students and IT professionals, who wish to learn of the rich heritage of their new home, and I feel that this book will be a worthy addition to your bookcase and reference shelves of all libraries.

Book Review : EMC for Product Designers by Tim Williams

I had been invited to deliver a lecture on ElectroMagnetic Interference and ElectroMagnetic Compatibility abbreviated as EMI / EMC. 

This gave me a chance to brush up my rusty knowledge.

Here are a few book reviews I had written earlier when I used to regularly teach this subject at the Post-Graduate Level and conduct specialized training on EMI / EMC too during my faculty days at IAT later known as DIAT Deemed University and MILIT located in the hills of Girinagar near Pune.

This is Part 3 in this series.

BOOK REVIEW
Most of us consider a number of factors, exoteric and esoteric, while designing or selecting our homes and in the configuration of the numerous modern technological devices and domestic appliances, most of them electrical and electronic, especially in location of various rooms and in deciding where to place these appliances.

Recently I saw a programme on TV where a Vastu Shastra expert was advising viewers not only regarding the various aspects of designing and building living environments that are in harmony with the physical and metaphysical forces but also specifying optimal locations and layouts for various electrical and electronic appliances and devices in both residential homes and workplaces.

I listened with intriguing interest as he gave precise directions and specified exact locations for positioning of Televisions, Computers, Communication Devices, Microwave Ovens, Music systems and other appliances, and fascinated by the congruence between principles and aspects of Vastu and Electromagnetic Compatibility (EMC) and wondered whether the expert in reality was actually an EMC Design Engineer in addition to being a Vastu Shastra Specialist.

When you design or select or configure your house or office I am sure you consider various aesthetic, architectural, financial, utilitarian, geographical, interior and exterior design and other practical aspects, maybe even incorporate the principles of Vastu Shastra and Feng Shui etc.

But do you give even a fleeting consideration to Electromagnetic Compatibility (EMC)?

In today’s world with the increasing use of electrical, communication, electronic and information technologies we are under continual exposure to Electromagnetic Field (EMF), both inside and outside our homes, in our workplaces and even in the open wherever we go, radiating from radiating from electricity power lines, household wiring, microwave ovens, computers, monitors, televisions, communication devices, cellular phones, electrical, electronic and IT appliances.

“Electro-pollution” is an increasingly serious form of Environment Pollution and merits serious consideration, as much as, if not more than, other well-known forms of pollution.

Electro-pollution seems to be omnipresent. 

Apart from hazards to our health, Electromagnetic Interference (EMI) is detrimental to the proper functioning of most electrical, electronic, IT, ITES, ICT, communication and technology-based systems and may cause malfunctions and even potentially disastrous and fatal accidents.

The book being reviewed – EMC for Product Designers by Tim Williams – is one of the most comprehensive reference books I have read on the subject of the Design Management aspects of Electromagnetic Interference and Electromagnetic Compatibility [EMI / EMC].

The book comprises sixteen chapters arranged in three parts:

1. Legislation and Standards

2. Testing

3. Design

The author lucidly covers most micro and macro aspects of EMC Management in meticulous detail.

The logical sequence of topics, clear diagrams, tables and illustrations facilitate easy understanding of this complicated subject.

The Design Checklist, interesting Case Studies and useful mathematical formulae in the appendices and the extensive bibliography add value to this reference book.

Whilst the earlier chapters provide an excellent understanding of the EMC Standards and the basic theoretical principles of EMI / EMC, the “meat” of the book lies in the chapters on Systems EMC and EMC Management which encapsulate all relevant facets of EMC in a holistic manner.

I wish the author had included a detailed chapter on Electromagnetic Health Hazards and mitigation techniques. 

Electromagnetic Pollution (Electropollution) the most vital topic concerning all human beings seems to have not been accorded the due importance it deserves and I hope the author presents a more holistic and systemic view of EMC and includes a comprehensive chapter on pertinent aspects of Bio-electromagnetics, Thermal and Athermal EMR Hazards and their mitigation in the next edition.

I recommend this book – it is an excellent reference book for Electrical, Electronic, Telecommunication and IT Engineers and Managers, Designers, Students and practicing professionals in the field of EMI/EMC and a useful addition for all engineering and technical libraries.

EMI EMC RADHAZ - Biological Effects of Microwaves - Book Review

ELECTROMAGNETIC INTERFERENCE AND COMPATIBILITY (EMI / EMC)
Reference Literature Survey 
Book Review : Biological Effects of Microwaves by S Baranski and P Czerski

I have been invited to deliver a lecture on ElectroMagnetic Interference and ElectroMagnetic Compatibility abbreviated as EMI / EMC. 


I have decided to speak on the topic of RADHAZ also known as Electromagnetic Pollution (or Electropollution).

This gives me a chance to brush up my rusty knowledge and let me begin by going through a few book reviews I had written earlier when I used to regularly teach this subject at the Post Graduate Level and conduct specialized training on EMI / EMC during my faculty days at IAT later called DIAT Deemed University and MILIT located in the hills of Girinagar near Pune

So, Dear Reader, in case you are interested in this topic of Electromagnetic Pollution and its manifestations, do read on:

BOOK REVIEW

Biological Effects of Microwaves by S Baranski and P Czerski
(A seminal reference book on Electropollution Effects)

The Book

Title: Biological Effects of Microwaves
Authors: S Baranski and P Czerski
Published by: Dowden, Hutchinson and Ross, Inc., Stroudsburg, Pennsylvania, U.S.A. (1976)
Pages: 234
ISBN: 0-87933-145-3

Book Review by Vikram Karve
               
Electromagnetic Radiations emanating from various communication systems and devices like Radio and TV broadcasting, satellite communication, cell phone and mobile phone transmitter towers, microwave ovens and electrical and electronic appliances have now become an unavoidable area of our life. 

Today, especially in modern urban life, we are surrounded by electromagnetic radiation.

Microwaves constitute a significant part of electromagnetic radiations and contribute to “electro-pollution” as research indicates that microwaves affect living organisms. 

The book ‘Biological Effects of Microwaves’ by S. Baranski and P. Czerski presents the detailed research work done in this field and is one of the earliest books on the subject.  

It will prove helpful for the biologists, physicians, physicists as well as budding and practicing electronic and electrical engineers.

The content of the book is organized in seven chapters.

Chapter number one is the ‘introduction’ with the subject. 

At the beginning of this chapter the authors make our concepts clear about the important terms like microwave radiation, ionizing radiation, non ionizing radiation and radio-protection. 

Before dealing with the microwaves we must know about the electromagnetic radiation spectrum.

There are figures, illustrations and tables describing the electromagnetic radiation spectrum, the wavelengths (cm), energy (eV) of different waves like radio-frequencies  microwaves, visible light, UltraViolet Rays, X rays and Gamma rays and explaining some examples of typical uses of equipment generating radio-frequency and microwave radiation.

This chapter explains the uses of different ranges of frequencies, their respective applications, their occupational exposure and some examples of potential exposure (i.e. general population hazards). 

This chapter also explains the theory and working of various microwave transmitter valves such as magnetron, klystron – Reflex Klystron and multi-cavity Klystron and Travelling Wave Tube  (TWT) briefly with their schematic representations.

The second chapter is about the ‘Physical Characteristics of Microwaves’. 

This chapter is designed in such a fashion that the reader who wants to enter in this field but have forgotten some of the basic concepts of physics related to the microwaves. 

This chapter is important and helpful to grasp the further concepts. 

It includes the basic phenomenon of formation of electromagnetic wave, set of parameters that characterize the electromagnetic waves such as frequency, velocity, wavelength, Electric and magnetic field vectors, relation between the two and the characteristic impedance. 

Coaxial transmission line, coaxial cable and waveguide are also explained to understand how the waves are propagated.

After getting introduced with the microwaves and going through their physical characteristics, in the third chapter we study the interaction of microwaves with the living systems. 

Biologists and physicians studied the interaction of microwaves with the living systems and they came to the result which had three phenomena like penetration of microwaves into a biological target and their propagation within it, secondly the primary interaction of microwaves with living matter and the secondary effects induced by the primary interaction. 

The three layered semi-infinite slab model of a biological target (which is made up of skin, fat and muscle) illuminated by simple wave front is explained and may be used for solving various problems relative to the medical use of shortwave and microwave diathermy. 

In the later subsections primary and secondary effects of microwave interaction are studied. 

There are illustrations of the primary and secondary effects of microwaves on different levels of organizations ranging from molecular level to highly organized living systems.

The fourth and the most praiseworthy chapter of this book is titled ‘Biological effects of Microwaves (Experimental Data)’. 

It presents the collection data found in literature on experimental facts and observations on biological effects of microwaves. 

Various results of experiments done on different animals like mice, dog, rats, guinea pigs and cat are illustrated. 

Effects of microwaves on nervous system, cardiovascular effects, effects on endocrine and metabolic effects, effects on genital system, foetal development, chromosomal effects, possible genetic effects and cellular effects, effects on internal organs like abdominal cavity, chest and digestive track, effects on blood and the blood forming system, cataractogenesis are presented with experimental details. 

In the last section of the chapter some comments on experimental studies on the interaction of microwaves with living systems are done which are very useful while doing such experiments.

Chapter Five is about the ‘health status of personnel occupationally exposed to microwaves and the symptoms of microwave overexposure’. 

In this chapter the outcome experiments and conclusions of literature survey of various authors are given. At the end of the chapter the main points which are the outcome of all the survey of the literature are collected.

Microwaves are the boon for the mankind and improve our quality of  life in so many ways and it is prudent to be aware of the hazards and adopt safety standards to protect ourselves as well as the environment form the adverse effects of microwaves. 

Chapter Six is about the ‘Safe exposure limits and prevention of health hazards’ with analysis on the safe exposure limits of microwaves. 

The basic principles which may be used while determining the safe exposure limits are elucidated. 

At the end of the chapter suggestions for prevention of health hazards are given which are very much important while dealing with the microwaves.

The seventh and last chapter of the book summarizes the work presented in the previous chapters and the important developments in the field till the writing of this book. 

The authors suggest integrated coordinated interdisciplinary efforts of biologists, physicians, physicists and electronic engineers. 

The authors have done extensive literature survey for this book and cite more than 600 references which may prove helpful for the reader for further studies in this subject. 

This book was published in 1976. Though not a recent publication, this book is a seminal work and an important book of reference literature in its area and will prove useful for those who are doing research in this field.
