1 comments about Electrician's Technical Reference: Motors (Electricians Technical Reference).

1. I found this to be a readable, thorough text that adequately covers the subject. A fair number of pages at the end are devoted to reference material -- dimension tables and tables of typical values for real-world motors -- which I found valuable. Criticisms include proofreading - several equations substitute the number "12" for "I squared" which made for a real headscratcher until I figured it out. The line drawings that illustrate the text were apparently supplied by Siemens as this company's name appears prominently on them. This seems parochial to me and should have been edited out, or other illustrations used. I thought that the treatment of phase relationships and rotating magnetic fields was less than rigorous, taking a phenomenological approach rather than an analytical one. It would appear that any material requiring a knowledge of trig and calculus had been stripped out, which is unfortunate. Still, not a bad text overall.

5 comments about The Woodburner's Companion: Practical Ways of Heating With Wood.

1. In an age of rapidly rising energy costs for the homeowner, fresh attention is being given to heating alternatives to electricity and natural gas. Foremost among them is the woodburning stove and/or fireplace. Dirk Thomas is a Vermont chimney sweep how drew upon his many years of experience and expertise to write The Woodburner's Companion, a definitive "how to" manual and guide on the proper ways to utilize wood and fireplace stoves, boilers, furnaces, masonry heaters, and more. Thomas comprehensively covers such pertinent issues as the fuel value of various woods, how to purchase firewood, getting the most heat from what you buy, the environmental impact of woodburning, and a variety of chimney and flue arrangements for best efficiency. Curry provides specific emphasis on the safety issues involved with burning wood for fuel and heat. "Must" reading for the novice wood burner, The Woodburner's Companion will also offer considerable value for experienced woodburners with detailed discussions of woodstove installation, and American and Canadian building and fire codes.



2. If you operate a woodstove, you should have this book. It covers every topic the woodburner should read prior to purchasing, for installation and operation. The information on safety, cleaning and chimney problems is vital. The advice on buying wood will prevent a rip-off (very easily done in the cord wood biz). Woodstove manufacturers should ship this book with their stoves. Highly recommended.



3. In his earlier, complementary book "The Harrowsmith Country Life Guide to Wood Heat" Dirk Thomas lays out burning wood for heat from A to Z. Everything is covered from felling and limbing trees, using block and tackle to move them on any kind of surface, rigging up trucks to remove trees on hillsides, bucking wood, to installing stoves and chimneys. "The Woodburner's Companion" is more for the less adventurous homeowner who gets his wood ready-to-go or who is building a new house with woodburning in mind.
   As such the book is very useful. Heating values of wood, fuel, coal and the like are compared, stove installation and chimney maintenance are covered in some depth, and enlightening facts about clean burning and types of creosote are discussed. I especially value Thomas's remarks on the best way to keep a proper fire in a wood stove going, which is to neither frequently feed it all the time nor starve it down to embers.
   He covers types of chimneys, pros and cons of various materials, chimney cleaning techniques, and how best to handle fireplaces and fireplace inserts, as well as wood stoves and wood furnaces.
   This is a capable book whose information will get the novice off to a flying start and hone the woodburning skills of the veteran. It will enhance efficiency and safety in the home.



4. I found this book to have answered every question that can come to mind involving burning wood either as a primary source of heat or esthetic enjoyment. It is enjoyable reading as well as informative. I particularly enjoyed the pros and cons revealed about different methods of wood heat and also Dirk's subtle sense of humor in defending the burning of wood as an institution---as he so aptly states, it is defensible politically since no wars have been fought over wood (unlike oil), and if you have a wood spill, you're not looking at a major ecological catastrophe. It's not hard to see that Mr. Thomas likes his trade (chimney sweeping)and is the best choice to write a book of this nature. To all prospective readers: Enjoy!



5. I have burned wood in a woodstove for years, but there was a lot that I didn't know, especially regarding chimney safety. I will be having my chimney inspected for cracked flue tiles, since I know that there was once a chimney fire (before my time). I don't want to endanger my family to save a few bucks. Thank you, Dirk, for writing such a clear and sensible guide. I expect that more people will be using wood to heat their homes as fuel and electricity costs continue to rise. This book is well worth buying as a reference and guide to safely useing a woodstove or fireplace.

5 comments about Introductory Circuit Analysis (9th Edition).

1. Hello to everyone who reads my review of this book. First of all for those of you who will need a TI-86 calculator which this book calls for, dont worry about because doesnt even tell you how to use it for certain applications such as Super Mesh, Method Analysis and so on. I had to go to a student who was in a College Algebra class to learn how to use this calculator for this book! Second my professor shows better examples on solve the problems in the book which the book makes it so confusing. You have to ask the professor to show several examples to learn what the book is covering. I would suggest to professors and the Director/Chairman as a student, look for a book that you can use in the class other than this where students can learn from and not become so confused over the material to where almost every student in the class has to ask the professor several questions about the topic and meet with him one on one. I am speaking for other students by the way. I am also helping the professors also. Get a book that students can learn from instead of a one on one discusssion with the professor. Some thing else other than this book! Thanks for your time reading my review. ~Scott~



2. First of all,this is the best introductory book I have ever read. Boylestadt does an excellent job of getting to the point on the subjects he talks about.The tools he explains in network theorems are very good for the ones who wish to bone up on their skills. You might want to have some other books that explain the subject a little simpler,but you have to work any way to get at that knowledge level.This is a good class room book where one is in a group and can communicate the thoughts they have leaned from the book.
   This book is not about devices such as transistors and diodes but its about how accurately you can analyze the circuit. On top of that every mistake he makes in one edition,he corrects it in another edition. So you can guess that this book is pretty good.You don't necessarily have to have a TI-86,but it makes the work flow pretty easily.You need to know what an integrand sign means but for the most part it is a very readable book.
   Boylestadt has books out on devices,too. If it's like this book
   you know its very knowledgable.



3. Is there a reason that the experiments that are suppose to accompany the 11ed book are based off the 10ed book?



4. Okay, I'll be the first to admit that I'm not the brightest bulb in the pack, but I'm not really that dim either. I thought I was the only one that didn't understand how they get from the example problems to the end-of-chapter problems until I read several reviews from others who had the same problem.
   
   My instructor keeps telling everyone that has problems in the class, "Wait until you get to Digital Fundamentals - that will really give you trouble." Hmm, I've had DF and earned an A. Yes, I had to study and work hard at it, but at least I was able to understand getting from point A to point D!
   
   At this juncture it is either get out while I can, without a grade penalty, or hope that I can catch up by going thru other books. I have ordered other books, but will be trying this class again next semester. I wish I had known at the beginning of the semester that I would need further texts to fill in the blanks!



5. Boylestad is still alive??
   I just ask that, tongue-in-cheek, to point out that this book has been around a long time. I used this book in a couple of college Circuit Analysis classes (1 Semester DC, 2nd Semester AC) in 1977. I had already had 2 years of electronic tech (okay, vocational school) during high school so I had no problem with this book whatsoever, it just built on what I already knew.
   But... several people in the class who were new to electrical fundamentals had significant problems with learning the material from this book. In the accompanying lab class I was excused from most of the labs and spent most of my time helping other students with their labs and tutoring them to help them understand the material that they were not absorbing from the textbook. I just took a look at a pirated copy of this book that I found online and the presentation is basically that same as it was 31 years ago, so I am not surprised that some people still have problems. After I graduated from college I came across a used circuit theory book by Floyd, which was incredibly clear in its presentation, so I grabbed that book for my reference shelf, and Mr. Boylestad's book went in the dumpster. Oh, as I recall, the beginning of the AC section was especially terse and difficult for the students; Boylestad's presentation of the j-operator math made a simple subject seem difficult.

1. I knew nothing about wiring or electricity before I read this book. It was very easy to understand and covered everything very well. The wording is not too difficult to comprehend. I reccomend this book for expirienced as well as inexpirienced electricians.
