Weitere Fakten zu POM
Hohe Festigkeit und hervorragend zerspanbar
Polyoxymethylene (POM) sind technische Thermoplaste, die durch Co-Polymerisation von Formaldehyd entstehen. Wegen ihrer chemischen Struktur werden POM-Kunststoffe häufig auch als Polyacetale bezeichnet. Sie besitzen eine hohe Kristallinität und zählen zu den steifesten und festesten thermoplastischen Kunststoffen bei gleichzeitig guter Zähigkeit, Oberflächenhärte und niedrigen Reibwerten. Polyoxymethylene werden häufig als Präzisionsteile in der Feinwerktechnik verwendet und dienen als Substitute für Metalle.

Excellent advice
Format: Paperback
I've been working in College Student Affairs for almost 10 years (admissions & academic advising.) I bought this as a gift for my godson, who was a sophomore in high school at the time. I chose this book because it didn't put pressure on kids to pick the big name school with the highest price tag they were accepted to. It gave good advice bout finding out and figuring out what schools would be a good "fit" for them. It also had some good advice about taking & prepping for the SATs - which made it a good choice fod my godson even though he is a couple years away from filling out his applications!

Highly Recommended
Format: Paperback
Superb book that eased my parental anxieties and has proven very helpful to my college-applicant daughter. Even though it was published in 2011, it is *not* dated (something I worried about). Sure, it will probably need an update by 2020 or so, but most of the info is not very time-sensitive to begin with.

Good place to start
Format: Paperback
I am an independent college adviser based in California and I recommend this book to my clients but only at the very beginning of the process (mostly to the parents of rising high school freshmen and sophomores).
This book is a good place to start especially for many of the foreign educated or immigrant families, who are new to the US College Admission process. The parents do tell us that the book loses its effectiveness once they gain knowledge of the process and/or they begin working one-on-one with an independent and/or become more conscious about meeting the high school counselors early in the process.
I personally like the fact that once this book is overviewed by the families, we can spend more time addressing specific concerns and giving more customized advice. As a result we only need quarterly meetings and these meetings are extremely targeted.
The problem with this book though is it reads like a huge information session by colleges. Those of you who have attended some of the information sessions will know what I mean. The insights provided by the deans and admission officers of various colleges sound somewhat like a "sales pitch" at times and at other times are misleading. I also recommend my students to keep their knowledge up to date by referring to various free resources such as Nancy Griesemer's educational articles in Washington Examiner Online, or the Choice Blog. I spend considerable time volunteering my services at a high school in a mixed/low income neighborhoods; I wish the price had been more reasonable considering that this is a basic book.
Lastly as members of NACAC (National Association of College Admission Counseling), all of us in the admissions field (College Admission Officers, High School Counselors, and Independent Counselors) subscribe to certain codes of ethics and one of the Statements of Good Practice says this about Fairness and Equity: We believe our members have a responsibility to treat one another and students in a fundamentally fair and equitable manner. Unfortunately, Ms. Mamlet and Ms. VanDeVelde do a great disservice by being disrespectful to a large community of Independent College Advisers, many of whom are needed when the high school counselors are juggling with case loads of 200-300 students each and are unable to keep up with the changing scene of college admissions (either due to the lack of funding or time). Gone are the days when people went to some "quack-independents" who promised admissions to Ivy Leagues--sure there are some of those but if families are careful in their research, they will soon find out that these Independents do not belong to any authentic professional organizations such as the NACAC, HECA or IECA. Most students who come to the authentic professionals are motivated to find their right fit college, explore their own strengths and weaknesses and find the best match for their talents, interests and financial situation. Most independents offer services that are reasonably priced. If Ms. Mamlet and VanDeVelde show more commitment to researching folks on the other side of the spectrum, I am sure that their book will be more enlightening.

Best College Info Book Ever!
Format: Paperback
I have read dozens of college-related books in the past 4 years, and this one ranks the highest by far. Written by industry experts and the authors got a lot of top talent to contribute. Full of real-life advice and useful information that is actually true (I fact-checked this against some other info).
I read parts of it out loud to my junior on the plane en route to a college tour, and she actually listened! Humor is always appreciated, and these authors use it without going overboard.
Great information, well-presented. A must-read!

A Must-Read for College (and Even High School) Students
Format: Paperback
First of all, this book really cuts to the point. If you are skilled with skim-reading, you can get this book in about 2 1/2 to 3 hours.
Second, while these strategies are currently untested by me, they seem really practical. Rather than saying "study" or "write paper" or "take test", Dr. Newport lays down specific, useable guidelines for all areas that are intended to cut down on time spent on schoolwork. This helps you with more time to have fun, do extracurricular activities, or work 60 hours a week (like I will soon be doing).
Third, this is THE anti-procrastination book, although I don't get the concept of starting term papers a month before they're due as the examples did. The whole concept behind this book is making sure you've got as little work going as possible that takes as little time as possible. Doing things upfront will ease your load later when the assignments and papers start rolling in and out.
There are only a couple of issues I have with the book.
1) Dr. Newport almost makes the use of personal laptops compulsory in college. I get why it would be such an asset, but for some of us it is more of a liability than an asset. I really believe one can get through college without a laptop at a much smaller personal expense than the costs of buying a laptop/accessories, printer, ink, etc. If you already bought one, that's one thing, but if you haven't, why do you need one? Just use pen/paper and the computer labs' computers and printers. With the printers, odds are you're paying the same amount for 1000 pages that you would for toner (paper is free with the way they price it), and you don't have to drop the cost upfront, but pay as you need the printer. Financially, you're better off skipping the personal printer.
2) He didn't discuss what format to purchase textbooks, but considering he was so insistent on portability, I would probably haphazard a guess that a hard copy is the only way to go. Sure it may be expensive, but what if your Kindle or iPad gets stolen?
Overall, highly, highly recommended. Get this for your child as an early (or very early) graduation present. Teaching them these things will save them a lot of headaches later on.
One last note: This book is not for the lazy. If you aren't willing to do the work, don't expect this book to help. However, if you're someone like me who's sick of lazy and wants to convert, this book IS for you!
