Saying by words of an amateur, omitting unnecessary details, rapid prototype is a piece of pre-project information, sometimes a graphical model, including all necessary data to produce any type of product (be that a piece of machinery, or medical equipment) . Rapid prototyping is taking into account all possible advantages and disadvantages of the product, it can be used in any sphere, for example, engineering, machinery construction, architecture, medicine. Whatever we are talking about – creation of a plane, surgical bur, building of a museum – rapid prototyping will help to see the result beforehand, considering all disadvantages of the project and calculating everything to a fine art.

Simply speaking, rapid prototyping is a preliminary testing of any merchandise. Nothing can be sold or passed to the client until it is not checked, researched and properly analyzed. Everything must be taken into consideration and here it goes not only about desires and whims of a potential client, but also about reliability, efficiency of the product. Everything is important here and a lot of people are included in the process, programmers, and creators, people who test the merchandise and decide whether this product is good or not and what improvements in requires. And only after all these arrangements the merchandise can be actually approved and produced.

Usually rapid prototype looks like a small copy of the future project. If it goes about a building or an airplane it’s going to be the miniature including the most important details of the object to be created. The most positive side here is that a client can see and touch the object he or she is going to create. As all details cannot be drawn on the model, other important details the future construction cannot do without are usually displayed on the screen by means of projector.
There is a notion in prototyping called ‘hollow box’. It means that if there are some details that prevent the project being carried out fast and qualitatively, it mustn’t be included into the demo of the prototype model.

Prototyping has a number of advantages, such as:

1. A prototype helps to define the quantity of materials and components that will be needed for a project.

2. Creators can define the exact time needed to carry out the project and final functionality of the product.

3. It becomes possible to define the scope of the future project or application.

4. Prototyping makes it possible to implement technologies methods that haven’t been used in production before.

5. The product will be enhanced according to the prototype.

The presence of the client during the development of the project is a very important part of the success here. The clients can advice to change something if he keeps his eye on the process and make needed amends. Only on the assumptions of all these factors the success will be guaranteed.

Over the recent decades rapid prototype services managed with solving lots of tech problems. And rapid prototype might help you to. Please make sure to read more about the rapid prototype technology and how it helps.

Rapid prototyping is a method used in such spheres as concept designs and it is usually carried out in different applications. It can also be implemented in medicine, industry, engineering; actually, there is no limit to spheres where rapid prototypes can be used. To put it in simpler words, the starting point of rapid prototyping is the word simulation.

The process of rapid prototyping consists of several levels. The first one is creating graphical model on the worksheets or drawing boards. Then the project is demonstrated with the help of projector or other digital equipment. Planned surgical procedures involving computers reflecting the process which is going to take place can serve as an example here.

For example, if the brain surgery is going to be carried out, 3D application can help to model the result and doctors are able to program the needed shape of the scull. These arrangements can help to make the risk during the surgery much lesser than it could be without computers.
Modern epoch is the epoch of vectors, epoch of mathematically calculated number of images, processed by machines, image aberration or calculating error practically reduced to zero. Both in industry and engineering, and also in other mechanical spheres any material object is preliminary designed by means of rapid prototyping.

Rapid prototyping become more and more popular nowadays, first of all due to its flexible enormous capabilities and perspectives. Clients, using rapid prototyping can easily manage the needed materials without necessity to keep the bulk of papers and sketches, they can delete these material whenever they want, saving only the needed ones.

Rapid prototyping is not only reliable; it is the most suitable way of storing and processing than one could ever imagine. All rapid prototyping models are being created by means of 3D graphic manipulator, which makes them easy in processing, changing characteristics of the model, such as shape, size and other parameters. Moreover graphic rapid prototyping models are perceived better visually and mentally, as illustrative examples are always perceived better.

Designing rapid prototyping models takes not only much time, but it also requires a long-lasting and organized teamwork, which is the greatest part of success here. Rapid prototyping has begun the part of any high-precision process or mechanism, the creation and future profitability of which must be thoroughly considered and predesigned which is the aim of the rapid prototyping itself. Usage of rapid prototyping in medicine (especially in surgery) is also of great importance, taking into account that it can help a number of people’s lives.

Together with modern world and technologies, rapid prototyping continues to develop and improve. Despite the necessity to spend money on it, huge organizations and corporations cannot do without this modeling system, which becomes more and more efficient each day.

The word ‘Sustainable’ appears to be the buzz word of the early Twenty-First century. It’s increasingly used by politicians and the government, business and marketing, media and entertainment and ordinary, everyday people. It is used in all kinds of discussion and debate, policy and purpose, subject and science.

Increasingly used is the term ‘Sustainable Living’ and for a really good reason.

The best definition of Sustainable Living I have come across is; “Sustainable living is fundamentally the application of sustainability to lifestyle choice and decisions. Sustainability itself is expressed as meeting present ecological, societal, and economical needs without compromising these factors for future generations. Sustainable living can therefore be described as living within the innate carrying capacities defined by these factors. “ See Earthhuddle.com for a diagram which will enable a better understanding of this definition.

There are several other definitions of sustainable living that may be easier for some to understand. For example, sustainable living is “a lifestyle that can be sustained without exhausting natural resources. That is: living simply and efficiently, and making everything we do use last as far as possible and achieve as much as can be achieved”. Whilst this definition of sustainability is quite acceptable, it does tend to focus on the environmental or ecological aspects solely and does not address society and the economy, topics that must be included in today’s world if we are to be truly sustainable.

The expression “sustainable living” has arisen quite rapidly as a result of the present economical, social and environmental challenges we must face. Many words and phrases have arisen with this, such as sustainable living, sustainable practices, sustainable housing, sustainable development, sustainable energy, sustainable business, sustainable agriculture, sustainable forestry, the list goes on. All these are enormously important to the overall sustainability and sustainable living dimension and there are many individual articles written about these topics.

Sustainable living is absolutely essential. History has shown us that cultures collapse and disappear when they are no longer sustainable. However, with reckless overuse of the word or phrase by politicians, business, media and the likes, are we in danger of abusing the word so much that it loses its value, importance and impact? Is the word ‘sustainable’ becoming unsustainable?

Sustainable Living or sustainability is a subject we must all familiarize and educate ourselves and others about. Sustainability affects every level of organization, from the local family to the whole planet. It encompasses all challenges facing us. It is something we must strive towards for the survival of humankind as we know it.

Self sufficiency is an important term to understand as well, for self sufficiency – the ability to provide for your own needs without depending on others – is an extremely important strategy to achieving sustainability. It is sobering to realize that self sufficiency and sustainable living are necessities of life for 80% of the world’s population. These people are considered by many westerners as being the poorest of people living on the planet. Does this mean we have to become poor as well? The simple answer is no. See our article “The Self-Sufficient Manager” on Earthhuddle.com

Sustainable Living, in summary, is a beautiful thought. It brings thoughts of community, happiness, independence, health, beauty, harmony, prosperity, and will give us all a bright future. Let’s all do our little bit to educate ourselves and understand the little things we can all do on our healthy quest for Sustainable Living.

Reading is one of the oldest cultural pursuits known to man. It hasn’t altered significantly for hundreds of years. There have been developments in the technology used to publish, handwritten manuscripts were superseded by the printing press, handset type gave way to computerised printing presses – but basically we read words that were printed on paper. However, it does appear as if there is set to be a major change in reading thanks to the development of electronic books readers.

Devices such as the Amazon Kindle reader allow readers to download books electronically and read them on the reader itself. There are no printing, no ink and no physical product distribution costs. All of this means that e-books are not only cheaper to buy but more environmentally friendly as well.

Newspapers and magazines can be sent wirelessly to your Kindle reader.Currently Amazon have the only reader device with wireless connectivity – but Sony will be releasing their own wireless reader – the Sony Daily Edition reader – before the end of 2009. Other manufacturers, such as Apple, Samsung and Plastic Logic, have new readers either due for release in the near future or in development.

In the academic publishing world, normally thought of as very conservative, electronic textbooks have already been introduced. A number of colleges and universities have teamed up with Amazon, to take advantage of the large format Kindle DX’s suitability to display text with graphics and pictures. In California, Governor Arnold Schwarzenegger has announced that his state will make free electronic textbooks available to students. This program has already commenced, having been launched for selected academic subjects in the Fall of 2009.

Meanwhile, in Washington, the New Democratic Leadership Council issued a white paper entitled “A Kindle In Every Backpack”. The report called for the free issue of electronic textbooks to students as a way of both cutting costs and keeping textbooks more up to date.
Even the way that we borrow library books may soon change. Sony’s Daily Edition reader will incorporate software which, when used in conjunction with local libraries, will allow members to download electronic books “on loan”. At the end of the loan period the e-book will simply delete itself from the reader.

It seems that almost every aspect of reading and publishing – normally thought of as a very conservative and traditional area – is undergoing a major transformation. Electronic book readers, and the e-books which are stored and read using them – seem to be an idea whose time has come. The financial benefits, the environmental benefits and the added convenience for the end user seem set to ensure that these readers will become an integral part of everyday life in the near future.

Would you like a closer look at those beautiful birds soaring above your cottage? You could pull out those dusty binoculars in the basement, or you could get an up-close look with a spotting scope.

These compact telescopes allow you to see images at a distance with unbelievable clarity. Whether you’re a devout bird watcher, have an interest in amateur astronomy, or are going on vacation and want to get up close and personal with the gorgeous scenery, spotting scopes can definitely enhance your experience.

vision scopes
A scope for spotting is well suited for such activities as long distance birdwatching and nature study, telephotography and scenic observing. Although binoculars are a good option if you are not going to be a great distance from the subject, the clarity you get with vision scopes is so good that you’ll be able to see fine markings that you would not be able to see through a pair of binoculars.

Ideally, the objective lens should be at least 60 mm in diameter to provide a bright image. When choosing a scope for spotting, quality optics should be your prime consideration. Beyond that, portability is important. For example, if you plan on doing a lot of hiking, then you should choose a spot scope that is as light as possible.

To change magnification according to your needs, scopes have interchangeable fixed-length eyepieces or a single zoom eyepiece. With a vision scope, the observer can start with a low power magnification and then switch to a higher power as required.

optics scope
Zoom lenses change magnification power from 20 x to as high as 60 x with a single, simple adjustment. However, as with binoculars, scopes do not perform well in dim light. The image also becomes shakier as you increase magnification. Nowadays, many mid-priced scopes have excellent zoom lenses giving sharpness and clear images.

There are now a number of waterproof models available to choose from as well. If you are interested in amateur astronomy, which is a method of obtaining photos using a digital camera through a spotting scope, then select one that allows for the attachment of a 35mm camera body.

A tripod for spotting scopes is one of the best accessories that you can buy. Scope mounts stabilize your image and allow you to wait for your subject without putting the scope down. This is a great feature for bird watchers and hunters.

Since most scope users will need to be mobile, choose a tripod that is lightweight, is easy to adjust and has a flip-lock design. You should also make sure that it is sturdy and will not tip in high winds or on rough terrain.

amateur astronomy
The most expensive spotting scopes are not always the best. High priced models may not have the best optics. Choose the scope with the features and performance you and your budget will be comfortable with – but don’t go cheap either.

Don’t make any impulse purchases and know exactly what you need before you even go into the store.

It’s probably not unreasonable to say that we’re all much more environmentally conscious these days. It seems improbable that we are about to turn into a country of eco-warriors overnight, but most people are quite willing to make a little effort to be more environmentally friendly. It is actually a whole bunch of little changes by a large number of people that tends to make the difference. The good news is that you can be more environmentally conscious whilst saving both time and money.

For example, Carnegie Melon University conducted a study recently and concluded that shopping online is better for the environment than the traditional method of buying from retail outlets. The purchase of a flash memory stick was used as one example and it was discovered that the traditional retail method had an environmental impact which was 35% greater than making the exact same purchase on the internet.

A similar study – carried out by CleanTech this time – noted that the carbon footprint of a standard printed book was 7.5 kg of CO2 during the course of its life. However, this figure was multiplied by a factor of two if the customer got into their car, drove to the store, purchased the book and then drove home again rather than having it delivered by mail.

Approximately 65% of the emissions generated by traditional shopping methods are a direct result of the customer’s transport to the store and home again.

Shopping online and choosing postal delivery is not only better for the environment – it will save you time and you will often find what you’re searching for at a cheaper price. You can increase the environmental benefits even more simply by choosing the right type of product.

For example, if you opt to buy electronic books as opposed to the conventional printed type, you will save on paper, ink and the energy used in the printing and binding process. As a rule, electronic books cost less than the printed versions – plus you save on gas. You can even subscribe to get newspapers and magazines delivered to e-book readers like the Amazon Kindle reader every day.

Likewise, if you decide to download music to your PC or mp3 player, you will save on CDs, packaging and distribution emissions. Downloading movies, which you can now do from Amazon, iTunes and a number of other sites also has both environmental and financial benefits.

So when it comes to buying online, why not adopt a two pronged attack. Firstly, if you can avoid a trip to the store in your car by buying online then that will usually be a good option. Secondly, if you can swap downloadable products for physical ones then not only will you be doing your bit for the planet – but you will save time and money into the bargain.

The electronic book reader market may still be in its infancy but the early signs are that it is going to be a lucrative and fiercely contested marketplace. At the moment Amazon is dominating with the Kindle reader family. However, many of Amazon’s competitors have new readers in development, a lot of which are scheduled to launch before the end of 2009 or in early 2010.

For instance, the launch of the new Sony Daily Edition reader has now been set for December this year. The price will be $399 and it will have a bigger display than the Kindle 2 at 7” wide, which will include touch screen control, something that the current Kindles don’t have.

It will also have wireless connectivity – even if only to the Sony bookstore – provided by AT&T. Visitors to the Sony store will be able to access their local library’s collection of e-books using Overdrive “Library Finder” digital distribution software. Using a valid library card it will be possible for users to download e-books to their reader. These will expire at the end of the “loan”.

Looking at the device specification, it does ]spin]appear that|seem very much as if|look like[/spin] Sony has an excellent opportunity to catch up on Amazon. The wireless connectivity, with no monthly fees, has been a notable shortcoming of the Sony readers on offer to date. The touch screen technology is something that Amazon does not, currently at least, offer and will be seen as a positive advantage in favour of Sony by many.

Aside from the technological aspects of the various readers on offer, the choice and type of e-books available will be a significant factor in future. Amazon has a vast collection of e-books available at their online store. However, these are all proprietary to the Kindle reader. Sony, along with other reader manufacturers have made much of their “open policy”, the ability to read a variety of different e-book formats and this will also be a key factor in the development of the e-book marketplace.

For the moment, it appears that Sony and Amazon are going to slug it out. However, there are a raft of other competitors who will be launching new readers fairly soon. Apple will release a tablet PC, Plastic Logic have confirmed a 2010 launch for their virtually indestructible reader, and others such as iRex and Samsung are also working hard to ensure that they get their share of the future market.

Increased competition and choice is always beneficial for consumers. It’s to be hoped that prices will fall as the number of competitors increases and that, eventually, some common electronic publishing format will be defined as the industry standard in the near future.

Portable e-book readers have been available for a decade now – although you could be forgiven for thinking that they just recently exploded onto the scene in 2009. The Franklin eBookMan, released in 1999, is widely held to be the first dedicated electronic book reader – although it should be noted that there were some earlier devices, the Apple Newton is sometimes referred to in this context, which some may consider to be e-book readers.

Today, the most famous reader, and the undisputed (but not unchallenged) market leader, is the Amazon Kindle reader. Amazon can justifiably claim to have made a huge contribution to the development of the electronic book market. They are, of course, far from alone and there are something like a dozen other companies with portable readers available – including Sony, iRex, Plastic Logic and Samsung. Apps are available for the Apple iPhone and Apple are expected to release a tablet based PC by the end of 2009 (or possibly early in 2010) which would be ideal for reading electronic books.

Apart from the development work being carried out by major electronics manufacturers, there are a number of other initiatives ongoing which serve to promote the cause of electronic books.

For example, Governor Arnold Schwarzenegger recently announced that the state of California would commence supplying free downloadable electronic textbooks for students in the fall of 2009. Whilst Governor Schwarzenegger did not specifically refer to the Amazon Kindle, a new paper issued by the New Democratic Leadership Council – a Washington think tank established in 1985 which has Hilary Clinton as a member – did. Entitled “A Kindle In Every Backpack” the report suggests that each of America’s K-12 school children be supplied with a free electronic book reader which would be used to access digital academic textbooks.

It does very much appear that the concept of portable electronic book readers is an idea whose time has come. The technology is, if not fully complete, at least developed to an acceptable level. The infrastructure is there – both Amazon and Google have very large libraries of electronic books. The political will seems to be growing and the academic establishment is rapidly getting behind the concept.

At this time there is, understandably perhaps, a strong focus on the technology and the functionality of the reader devices. However, it’s worth speculating as to what all of this could mean for the future of books, reading and publishing in general. Here are just a few future possibilities:

Traditional book publishing patterns – hardback followed by paperback a few months later – will evolve. Electronic books will offer a low cost method to release new books and will be used to test the market.

Electronic book readers provided based upon cell phone pricing models. A low initial price is subsidised by a monthly subscription – or possibly a minimum number of books purchased per annum.

Electronic book readers given away free (or heavily discounted) to customers willing to enter in to a long term newspaper, magazine, stock feed or blog subscription.

Free books to download – but with adverts every few pages. We could possibly even see hyperlinks from naturally occurring but commercially attractive keywords in the text to advertiser’s offers. [Amazon already have a large number of free Kindle books available – and Google have a giant library of public domain titles on offer]

Free readers issued by the government to school children and students.

Free readers given to students by universities as an incentive to enrol with them. [This is already happening in August 2009].

The main derivative of antimony metal is antimony trioxide. This product has many uses including as a flame retardant synergist, a catalyst, a clarifying agent, an opacifier, or a white pigment. Because there are so many applications you will find that the industries using it are just as varied. You can find antimony used in the plastics industry, textiles, glass making, paint, construction materials, and porcelain and enamel.
Antimony oxide is a flame retardant synergist so it cannot be used by itself as a flame retardant. The antimony works in combination with a halogen flame retardant. To achieve the same amount of fire protection you only need to use half as much halogen if you include the antimony synergist. Many different kinds of materials use the antimony/halogen combination for flame retardant additives. Some of the most common plastics are high impact polystyrene (HIPS), ethylene propylene diene M- class rubber (EPDM), polyethylene (PE), epoxies, polypropylene (PP), polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), polyurethanes, and phenolics. Plastics companies use many additives like antimony trioxide fire inhibitor synergist in a variety of ways. You can buy antimony trioxide in large supersacks or multi-walled paper bags of various sizes. Other packaging options include drums or kegs. You will find that the halogen flame retardant is packaged the same way. If industrial hygiene is a concern, you can find some companies that will sell you a liquid dispersion that includes both already mixed in the right ratios.
The glass industry also uses antimony oxide as a clarifying agent. Many glass manufacturers purchase antimony oxide clarifying agent to help with the quality of their product. Clarifying agents are what makes it possible to have clear glass. The bubbles, inclusions, and colors that the glass maker does not want in the final product are removed by adding the antimony during the meltdown process. If there was no clarifying agent, the natural impurities in sand would turn glass light green or light blue. Some clarifying agents have problems of their own because over time they react with ultraviolet light, but antimony trioxide is not one of these. One example is with manganese oxide which turns the glass purple over time as it starts to break down.
Antimony is also used as a catalyst in the polymerization of polyethylene terephthalate or PET.The polymerization of polyethylene terephthalate or PET requires a catalyst and antimony is used for that purpose as well. PET is what is used to make water bottles or other containers. The material used for this purpose in generally of a higher purity than the material used for flame retardant or glass clarifying applications. Many manufacturers use this catalyst because the cost/performance ratio is very good. Other catalysts may work better than antimony but not enough because they are still too expensive.
One final use of antimony trioxide is as a pigment. It can be used as an opacifier for the porcelain and enamel industries often. Companies can purchase antimony is many ways like as a large particle size antimony trioxide and as a result it is used in many final products. No matter who you are or what you do, the chances of you coming in contact with a product that contains antimony or was made with antimony in the process are extremely high every day of your life.

The Aquamog was created in the early 1980’s by Aquatics Unlimited (AU). The McNabb family founded AU in the 1970

Both Tom and Dave McNabb created the Aquamog brand and line of equipment throughout the 1980s and 1990s while with AU. Tom continued the Aquamog line into the new century with the addition of the MarshMog. Tom’s new company Clean Lakes, Inc. located in Martinez, California and Dave’s company DK Environmental in Lafayette, California have been working together on the Aquamog CCX project for about ten years and in February 2009 the Aquamog CCX was introduced into the Aquamog family.

The machine know by a few as the swamp cutter; swamp rig; cookie cutter; tule cutter; various other names was in “no name land” so to speak. It did not fit the mold of first aquamogs as being a multi-purpose aquatic maintenance machine. But is has now worked its way into the Aquamog family of machines.

With ten years of testing and rigorous evaluation Tom and Dave thought that the machine without a name had finally proven itself as a true aquamog. The Aquamog CCX had meet all the critical challenges to become an Aquamog. The Aquamog CCX-238 has now passed all the tests and is ready to stand side by side with the rest of the Aquamogs.

What makes the Aquamog CCX special is its ability to get into places that can not be reached by the MarshMog or the Aquaomg PRX-163 and Aquamog SRX-109. In addition it has been found that the Aquamog CCX system of removing aquatic emergent vegetation such as cattails and bulrush can be performed in a fraction of the time and more efficiently than with the other aquamogs. This equates to a savings for clients and users of the machines.

Like with the other Aquamogs the McNabb’s have a unique way of naming the aquamogs after their best attributes. The Aquamog CCX-238 is no different. The Aquamog CCX-238 gets its name from the 238 horse-power Detroit engine that it has humming under the back hood. The CCX stands for “Cookie Cutter eXtraordinaire”. The “Cookie Cutter” part of the name was picked due to its ability to cut channels through any type of aquatic emergent vegetation with easy, just like a cookie cutter through dough.

The following is a list of some of the other aquamog names and how they where derived.

Aquaomg PRX-163 - 163 Horse Power and PRX stands for “Power Rig eXtraordinaire”
Aquamog SRX-109 - 109 Horse Power and SRX stands for “Small Rig eXtraordinaire”
HarborMog HRX-109 109 Horse Power and HRX stands for “Harbor Rig eXtraordinaire”
Aquamog WRX-225 225 Horse Power and WRX stands for “Walking Rig eXtraordinaire”

So you see it was only fitting to give the Aquamog CCX-238 is proper name. All of the aquamogs that where made by the McNabb’s will be featured over the next few months in a series at www.aquamogs.com. Please check those site for more information on the other Aquamogs and projects that they have done all over the world.
