Liver with a 3D printer. Innovative method of Polish student

Jan Witowski, a medical student at the Jagiellonian University, has developed an innovative, probably the cheapest in the world printing method 3D liver models. Printed copies are already helping in surgery patients. Operations with the use of 3D printed models are rare liver. The obstacle is primarily just the high cost.

Student from Krakow hopes that through his method manages to popularize 3D prints of the liver, which serve the medicine and will assist during the operation.

Polish model - 500 zł - 120 EUR foreign - several thousand zł - a few thousand EUR

Prints 3D models of organs, to facilitate diagnosis and surgery of the patient, increasingly used in medicine. But prints are rare liver. - The liver is a complex organ anatomically and print it is also complicated. The cost of production of one model of a 400-500 zł, while the other, the foreign models - several thousand. zł - says Jan Witowski.

Low production costs organ scheme by the Polish project arise primarily from printing capabilities in the average 3D printer. Foreign models are designed so that their print specialist is needed, the way the machine.

Expensive printer use to print primarily resins (transparent, colored, flexible) - thanks to all models come with the printer. According to the draft Vitovskoho plastic model elements (corresponding to the inside of the liver) are printed separately and then "flood" the corresponding silicon (which takes the shape of the liver).

He found a material which replaces resin

Polish student was able to find a material that is transparent (the model of the liver must be transparent, would see the internal structure of the organ) and was replaced by a transparent resin in expensive printers. - Selected by silicone us great works, so we can get past a very expensive machine and use ordinary printers that can literally put on the desk - he explains.

- Our solution is not nothing worse than much more expensive, the proposed abroad - provides Witowski.

For now, the model is used at the University Hospital in Krakow, but interest in it is growing among Polish and foreign surgeons. The invention now writes a specialist foreign press.

The precise location of the affected tissue

Liver 3D model accurately reproduces the structure of the patient's organ, thereby allowing physicians during surgery more accurately than CT scans to find altered tissues, including tumors, the position of which is sometimes difficult to detect using standard imaging methods.

- With great enthusiasm we approach this type of models, because they let preoperatively explain some of the intricacies of anatomy that can surprise us during surgery. With such prints, we know that the structure of the organ, which facilitates the planning and conduct of operations - says dr. Michał Pędziwiatr, a surgeon at the University Hospital in Krakow.

As he explained, the primary indication for liver metastases of other cancers (especially colorectal cancer) to this organ. The doctor added that there are not many places in Poland, which deal with the operations of the liver and therefore "it seems that the number of patients requiring surgery is greater than the number of places where you can perform these operations."

And why I write about it, but because when I started with the first gain some information about 3D printing is a thinker, with some incredible things is that in Poland there for maybe 50 years. It was in January or February of this year. Today, we have the end of May and it turns out that a student from Krakow away from Lancut about 190 km any discovered a new way to print liver model using a 3D printer. This is getting to be quite real. But it does not end. It turns out to be after reading the first few sentences that the student is a person who went to high school in Lancut that is in my hometown. and that to me is just so amazing.

In the US, vehicle printed in 3D

Electrical, printed in 3D vehicle conquers the US market

Local Motors Company, which created the world's first 3D car, unveiled Olli - equipped with the latest technology, electric vehicle that runs without a driver.

Olli was presented during the opening ceremony of the new building Local Motors in National Harbor, Maryland. Using an application like Uber and Lyft, customers can order a car to get to your destination.

Advanced technology

Bus, IBM Watson technology uses the Internet of Things, is equipped with 30 built-in sensors throughout the vehicle, which collect data allowing to take quick decisions. Sensors can be added and adjusted continuously. They can also take into account the local needs of passengers. The vehicle is equipped with a device that turn text into speech so that it can be interaction between the vehicle and passengers. The bus will also be able to answer questions how it works, where he was going and how it makes decisions. Olli can even tell you about the places through which a passes and also recommend local sights and best restaurants. The vehicle can accommodate up to 12 people. His track the environmental impact is negligible.

- Olli offers a smart, safe and sustainable transport solutions - said John B. Rogers, CEO and co-founder of Local Motors. - We are curious what the community will do with such advanced technology - he added.

Olli has a unique assembly process. Individual parts of the bus are created in the local 3D printing, and then assembled by specialists of Local Motors. The printing process takes approx. 10 hours, and the installation of about an hour. Production of the following vehicles Olli held at the headquarters of Local Motors Near Phoenix.

Bright future

Local Motors Micro plans to build hundreds of factories worldwide that produce vehicles designed to meet local needs. Such factories occupy little space, consume less energy and materials. Interest in the technology has already reported 50 countries.

Olli will be used on local public roads in Washington and at the end of 2016 years in the Miami-Dade County (county in Florida) and Las Vegas (state of Nevada). Currently, Miami-Dade County is testing a pilot program in which several autonomous vehicles will be used for public transport around Miami.

- Improved stability of local transport networks within the broader order to create sustainable cities within Miami-Dade County and improving the quality of life of residents is our top priority - said Carlos Gimenez, Mayor of Miami-Dade. He admitted that the county needs to do more to improve transport in the region and the use of autonomous vehicles is a big step in the right direction.

What is 4D Printing? - the next step for the development of 3D printers

For several years, we have witnessed the dynamic development of the technology  of 3D printing . We admire the fruits begotten thanks to her. This technique has great potential and could revolutionize the entire mechanics, medicine, space exploration and many other fields. And although it seems that we are still at the beginning of this road,  scientists  already are wondering what will happen next. And what will happen? Well, 4D Printing, naturally.

4D printing, or ... what?

Two-dimensional and three-dimensional printing no longer need to explain to anyone unless - in the first case we are dealing with a flat image, the second: with the spatial structure. So how can you go beyond these limits, in other words: So what is the printing technique 4D?

In print 4D fourth dimension is time. The effect of a printer is not a specific subject, but the band material, which later was formed in such a way as to turn into a predetermined object (shape).

Quoting New Scienctis:  "4D printing technique consists of printing objects in 3D, which then change their shape over time, and may move in a manner that mimics the natural processes" . Usage? It should be mentioned first of all three areas: construction,  medicine  and  space exploration .

How it's working?

All components needed to complete the final object are created using a 3D printer. Items are designed in such a way to fit as many elements in the smallest space. To do this, scientists use their knowledge, among other things,  the curve Hilbert . Thanks to this fact impossible to create a large object in a small printer, and this is one of the biggest advantages of this technique.

The printed intermediate objects have selected all the fold - upon exposure to water moving parts bend and twist to form the final construction. 

Another vision 4D Printing

Jennifer Lewis of Harvard University wants to simplify the process. -  "We decided to take a cue from nature and we looked at the complex shapes in the modified natural architectures, such as flowers."

The team led by z Lewis tried to emulate the characteristics of plant cells that contain cellulose fibers governing the extent of their movement. Researchers admixed such fibers (wood pulp) with a polyacrylamide hydrogel - gelatinous substance expanding in water. As a result, an item printed using a 3D printer with the addition of this mixture can only get longer, but do not grow on the sides.

The team of researchers also developed a mathematical model, which makes it possible to print objects with different types of folds, and even curved shapes. -  "We can program the bending, twisting, wrinkling"  - says Lewis.

To test their technique, a team of scientists has printed two flowers, which on the surface look the same, but under the influence of water develop in different ways. They tried to faithfully reproduce the specificity of orchids. The results - as most satisfactory. 

Anyway, see for yourself in the video published on the Harvard channel on YouTube:

What's next?

It is hard to predict exactly what will aim towards the development of 4D technology. However, you can take it for granted that this development shall be advanced. But we know what plans has a team of researchers from Harvard Unwiersytetu.

The team would like to use its technology in tissue engineering. An attempt will be to supplement the structure of living cells and ultimately breed new bodies. If it succeeds, we may be witnessing another revolution in medicine, this time in transplantation. It remains perhaps therefore no longer just keep our fingers crossed. 

And why am I writing about? A no because I can not hide that when printing in 4D will be used largely possibilities of 3D printers which again expands the possibilities of our company or The GCC Group

Installing the GCC portfolio Coin second part - the transfer of Coins project portfolio

In a previous post I described installations and synchronization GCC Coin wallet. Today, I'll show how to pass Coins from our offices that we have in the project portfolio. But to transfer these Coins first for safety we should set a password to our portfolio so that no one else could get to him.

1. For this purpose, the top menu select the command of our portfolio settings , and select the drop down menu from the top of the first command  Encrypt Wallet . 
2. It appears to us a window where we give the password twice that will be cushioned our portfolio and press the button OK .
3. When you press OK, you receive us another window where there is a warning about this to remember their passwords because when her forget it lose located on the Coins. Therefore, write down the password somewhere and let's keep it in a safe place for everyone. If we are already behind, click OK and go to the next step.
4. Here comes another message to us about the fact that all copies made against collateral portfolio will be useless. Therefore, let us remember that after the opening of our securitized portfolio perform a new backup.

Since our portfolio is already secure, now we can start to move our Coins.

5. After re-opening the wallet click on to get the GCC. This card is on the left side of the window of our portfolio. This is the panel that is responsible for sending Coins the wallet.
6. Here is located the address of our portfolio. It is very important and we will use it every time when you'll want to put some Coins our portfolio. It is something like your bank account number with the bank transfers. You have to be very careful how it was served to all.
7. For this purpose, a button Coppy Address .. when you press this button, we are sure that our address has been copied to clarifying and completely.
8. Then we enter our page GCC and log in to your administration panel. and our office, select the tab Wallet Verification that will be used to forward Coins.
9. A window will open as shown below. At this point we paste our address book that kopiowaliśmy in step 7. These are some of the major actions in the transfer of our Coins so let's do it all very carefully.
10. Now we go back to our portfolio. Click the Sign Message.
    
11. We show us another window in which to press the Sign Message or we sign our message. If your wallet is protected by a password, we can expect the appearance of the message to enter the password
12. At this point we enter our username by which you log on to our website GCC.
13. Here is our address book which was mentioned earlier. If you have not copied it on the GCC side, we can do it now.
14. In this field, we generated code by which we confirm the transaction. We need to copy it.
15. In the next step, again we go to the page and place the GCC Sign Code paste the copied code from the portfolio confirming the transaction.
16. the next step after re-checking is to accept our transaction with the blue button.
17. We opened another window on our website GCC. This field is our address book. We see it again and if the error repeat previous points already with the correct data. If everything is OK to proceed to the next step. 
18. At this point we give the number Coins that we want to transfer the portfolio. we do not need to transfer all at once. We can use transactions as the first test and send only a few Coins and then if the first succeeds done a complete transfer.
19. When everything is ready, click the button PAYOUT .
20. We show us another window on our website. Here we can still recall our transaction and leave our Coins in our office. If everything is OK it idziemy.dalej.
21. Now we go to our e-mail address and open the message that came to us from GCC Group. This is a security which by the end we have an impact on whether our Coins reach our portfolio. If you want to transfer them to confirm this operation by clicking the highlighted link. If not, just do not let us do just skontaktujmy the GCC Group.
22. After accepting e-mail messages of no return, and we commissioned the transaction will be executed. We'll see it on our website. Now we have to just wait for the posting of our operation that can take up to 14 days.
23. Now we have to check periodically whether our Coins already reached the wallet. For me, it took about 3 days. Well, we have completed our action Coins on the portfolio and we can dig.
24. Now only the last thing I check the status of a transaction on our website. After posting on the portfolio transaction status changed to paid. 

And this is the end of our transfer Coins the wallet. Now we just have to wait until Coins start to dig in and do not forget to do some backups of our portfolio.

Installing the GCC portfolio Coin Part I - installation and synchronization

Hello
Because at the moment in the GCC a lot of people moving their Coins portfolios decided to describe step by step how to do it. Because the material is pretty much decided to divide it into two separate posts. One in which only write about how to download and install the wallet. 

1. First we enter the page  https://www.thegcccoin.com and press the Download or download.
2. We opened another window shown below.
1. Here, we charge for portfolio websites.
2. The portfolio of the operating systems Windows
3. Wallet system MAC ,
4. The portfolio of the operating system LINUX .
3. If you select a portfolio of browser it appears to us in the 3 position portfolio option to go to the browser. In the other three cases will be available under the number 3 download option. I chose because your system portfolio, therefore, I click the Windows download.
4. Window will appear to download below. Select Save.
5. This step is quite simple when you select to save, click OK and accept our decision.
6. Now we need to find where he enrolled in our file. In my case, it is standard in the Download directory. Each of you should have selected a default folder for saving files downloaded from the web. In each of the systems may be called differently. the file will look like in the picture below and will be packed.
7. After unpacking we will file directory from which you can choose selected number 7 icon. When you click run our portfolio.
8. Below I presented the figure of the first launch of our portfolio. It looks quite nice. Strip marked with the number 8 is progress our portfolio of synchronization with the network.
9. This icon shows us the quality of the network connection the better will be the quality, the better for us.
10. Another icon shows us the status of the synchronization network portfolio. If the synchronization process is complete icon should light up in blue. Of course, after each power may take some time to ignite the wallet icon because first must connect to the network.
11. On the picture below, we see a good connection to the network, which will allow us to as stable as digging. This connection should be as powerful.
12. so it looks like the portfolio of sync icon with the network after its completion. In my case, it took less than an hour, but it can drag it to a few hours depending on the network connection you have, and what network traffic because it may be that at the same time synchronization is running on a large number of devices.

In this post is enough. after these operations should be synchronized portfolio. The next step is to move your Coins from the project in the portfolio, but more on that in the next post.

What can GIFT CERTIFICATE GCC Group

Today we will show something to a point I did not appreciate, and it turns out that this is one of the most interesting options that provides us Back Office Group is a panel of GCC. GIFT CERTIFICATE . What's this? It is simply a gift that you can buy your friend or family, for example, also to celebrate a birthday or holidays or without any occasion.

Below I will present step-by-step how to do it:

1. After logging in to our office OFFICE we go to the tab as shown below.

   

2. The next step is to select from the drop down menu options GIFT CERTIFICATE .
3. Shows us the page as in the picture below: In position No. 3 we have given information about the state of our funds in your account in the GCC Group.
4. In the next step, select the 3D pack we want to give to a person. Availability packet is dependent on having an amount of the measures described in the preceding paragraph. 
5. This field is very important here give an email address of the person you want to make a gift. If you leave it blank this certificate will be sent to our e-mail address and we ourselves will be able to give it to someone else.
6. The next field is the acceptance of 3D package purchased. By pressing this button simply buy the certificate.
7. We buy a separate certificate to pay for the shipment. Here you can choose the type of delivery that previously purchased for our partner. From what I know the costs of delivery must purchase a separate invoice or we go again points 1 to 3 and then go directly to step 7
8. In turn choose the country to which the consignment to be sent.
9. This last field enter your e-mail information which has come to take out a certificate of delivery.
10. Once we have everything ready as in point number 6 accept.
11. Presented below screen shows us the number we received our certificate after pressing the button BUY . The same certificate will be sent to our address an e-mail to the e-mail address that we gave when buying a particular 3D package. 
    
12. pressing the button we return to our office

On the part of the person who wants to buy a gift that so many can not even just that in an e-mail to the person for whom the certificate is purchased should precaution enter your registration link and describe it to use when registering for the program.

Now, what should a person do who get a gift from you?

13. A person endowed by our certified after opening their e-mail address will receive a message as shown below.
    
14. After opening the message we will see information about who bought you for a certificate and certificate number or the most important. This number will then be used for the purchase of a 3D after registration.                                                       
15. Message with the same information that is, with the certificate number will also be sent to the person who bought us a gift 3D package.
    
16. here you will find the e-mail address of person to whom the certificate was salted out /

To go to the registration it is best to open the referral link sent a separate message from your sponsor. It is true that this can be done directly from the email, but despite multiple trips me up attempts failed. I will not describe here since the beginning of the registration process, I will just post a link to the appropriate registration in the GCC Group .

17. After registration we enter into your office and you move tab invoice. appears below. In place of the 17 specified number of copy number of the certificate obtained in an e-mail.
    
18. In the next step comes alive button USE located next to the inscribed certificate. A window will appear as shown below.
    
19. In the open window after making sure that all is well accept the use of the certificate by clicking Save Changes .
20. The last step is to re-check after a few minutes of our invoice tab should look like. 
    
    invoice payment status changes to Gift Certificate and operations can be considered complete.

And what are the advantages of doing so:

• Someone we can make a very nice gift that some time may be really valuable,
• if we are people and we trust that they will pay us the cost of the purchased certificate is in my opinion the fastest way to accept payment by GCC Group. In my case, it took maybe 30 minutes, and was registered my account and I had paid the fees and extra points PVC.

What this course GCC Coin?

Today, some thoughts on the current value of the GCC COIN . Well, looking at the short reviews Coin as cryptocurrency we can certainly observe certain trends and what? A no such that up to a point that is until the end of the promotion or to 7 April 2017, the value of Coina steadily increased, reaching a maximum at the point of even 0.40 euros per 1 Coin .  After the end of the promotion takes place today fall in the value of the currency. At the time of writing this post when it is formed at around 0,021 euros. 

Many people are starting to say that the GCC Coin is a scam or some; SHITCOIN '. And why this is happening. Or maybe because it is the new currency at the beginning of its path and its value can not be measured in real terms by the end. 

In one of the first posts on the GCC Group. I wrote about the beginnings of Bitcoin. Then I found an article in which they wrote that the first transaction made using the first cryptocurrency  pizza was purchased for Bitvoinów 10000,00. If we wanted to spend today 10000,00 Coins for pizza after the current value would cost 210 euros. Now the question is how many pizzas you could buy for that price? Personally, I think that the start of our GCC currency is better than the first one. 

I think that now is the perfect time to encourage the purchase 3D packages because currently only receive them mighty Coins . The person deciding to purchase today can hardly have much to lose and profits in a few years could be considerable.

According to me, a lot of people wanted to quickly earn selling Coins at a price of 0.3 euros or 0.4 and reaching 300 or 400 percent profit. Those who had the Coins lot certainly something earned thus brought into a large sell-off of our cryptocurrency 

What can I say? I personally do not intend to sell their coins because I believe that for some time, but a lot of their value will increase. It all depends on how they will be put into circulation and how many things can be bought with it. And these things are dependent also already from the community of GCC. 

According to me, the less Coins will be more expensive to dig this will be their value. We now need to show all the possibilities Coin and where we can or will soon be able to use it. And certainly the potential is huge because it is behind a very innovative technology.
