Myth or Legend? Shark Deterrent Technology. Hear The Facts. You Decide

With such heated debate about the conservation of sharks, and the natural desire for safety in our waters, the use of electronic shark deterrent devices has become a necessary conversation that we simply must have. There is much speculation about the offered products, and for those that have that amphibious streak, there are a few pressing questions that are being asked: Does shark deterrent technology actually work? How does it work? And does it attract sharks and then deter them? Could an electronic deterrent device, such as Shark ShieldFREEDOM7, be thenewfound legend in our waters? Firstly, a shark deterrent has to be one that has the capability of producing a low frequency that disturbs the electro reception in a shark. Here is where the scientific hat must be worn, because to understand how the deterrent technology works, there has to be some understanding of what we are trying to deter, and for that matter, protect. All Chondrichthyans: sharks, rays, skates and chimeras, have Ampullary receptors in their heads, these are broadly tuned to low-frequency fields of

Interesting Facts About Robotics

Introduction: Robots are not a new idea, they have been around for age groups. In 1939, the first humanoid robot was created. It actually spoke over 700 words and appeared in a movie in the 1960s. There has been death by robot as well; in 1981 a Japanese worker in the Kawasaki factory was crushed by a robotic arm. The term "robotics" refers to the technology that has the main purpose in creating the mechanical intelligent agents called robots. Keywords: robots, science fun, human being The term "robot" was first coined by Czech writer Karel Capek in his play R.U.R. while term "robotics" was first coined by Isaac Asimov in his 1941 science fiction short-story "Liar!".The great Leonardo Da Vinci has predicted the creation of robots in future. At first mechanics was the great force behind the development of robots but as the science became more technologically advanced mechanics was replaced with electronics. The first digital and programmable robot was invented by George Devol in 1954 and is famous under the name of Unimate. RoboCup World Championship (the soccer games with robots) which started in 1997 is often used as a testing ground regarding the robot's dynamics and holy grail of robotics is to improve AI intelligence, particularly to create robots that would be able to integrate knowledge and put information into context so that they could make decisions in a split second.

The original idea behind creating robots was to use them do the work of humans, particularly hard work or work in a dangerous environment. Robots which must work instead of humans require some way to manipulate objects; pick up, modify, destroy, or otherwise have an effect and so far the science is finding it very hard to recreate human moves in robots. The current existing robots can walk or run but this movement doesn't look that similar to humans and it also uses great deal of energy which means that robotics needs to make future robots more energy efficient. Most today's mobile robots have wheels instead of legs. Today's robots are used for various purposes all the way from vacuuming floors, mowing lawns, cleaning drains to investigating other planets, building cars, as well as being used in military operations. Asia is believed to have more than half of all the robots in the world (particularly Japan that has over the 30% of all the robots in the world). There are some people who believe that the future development in robotics will cause big unemployment because robots would be able to do the skilled work better than humans, not to mention the fact that they would likely be more than able to exceed the capability of workers to perform most jobs.

Today Today, there are robots everywhere. They are used in the army to scout for bombs in war zones. They also fly over war zones to detect where enemies are located. Robots are used in factories as well to do repetitive jobs like tightening tire nuts on a car assembly line. Robots are also used in the medical field to do delicate surgery and can even be controlled from across the country. Interesting Comment The founder of a robotics institute predicts, in the next 4 years, humans will be having intimate contact with robots. He also believes that in 2040, robots are going to be their own species, with feelings and emotions. Conclusion: Through this article I am going to tell that, the future world is going to be run by robots.

What Secrets Can Numerology Reveal

Numerology is a very ancient teaching that consists of learning all about the numbers associated with your name and date of birth. The information found in numerology can be linked to your destiny, personality, your karma, the issues you have and the timing associated with your life.The formula for determining what your specific number are is simple. You can take the numbers in your birthdate and add them together. For instance, July 23, 1947 (07231947) adds up to 33. This is your master number. You then add the 3 plus 3 (6), which is your learning lesson number for this lifetime.What does that mean? Being a number 6 means that you are here to learn to be a teacher, a counselor, a speaker or a very responsible person whose purpose is to look out for other people. There is also a lot of artistry or creativity in this type of person. It could be a person with a social cause, (example: the 1960's was all about causes…getting out to vote, passing medicare) If your learning lesson number is 6 you might relate to the 1960's.

Another example we can take is a person whose learning lesson numer is seven. This number means that you are here to develop your higher mind and the truth. You like to uncover the truth and present it. You need to be around smart people or you will become bored. You are a teacher in many respects. You may lean towards being a researcher or detective.Where Does Ancient Numerology Come From?The first numerology schools you hear about were started by Pythagoras around 635 BC. In these circles it is believed that the soul literally names itself and imprints the name upon the parents subconscious to give to you at birth. It is a pre-structured event. Most people realize this, when they reach the age of 45-50 and know they need to do something different in their lives, so they change their jobs completely.

Here are some famous people who have four as their life path number . These obviously are people who love to produce, are very detail oriented and structured:Donald TrumpOprah WinfreyAngelina Jolie is one of the most famous fives who have to experience a lot of change and freedom in their lives. Tom Cruise is a very famous six. One couple that we know quite well, Tom Cruise, who is a six and Katie Holmes, whol is a one seem to show that certain numbers can be harmonious together.If you are just beginning to look into numerology, you should learn your learning number by adding the numbers in your birth date, and then you should take apart your name because all of the clues of who you are and where you are coming from are all there. You can discover what you really want and should be doing in your life.

3D-Printing Human Tissue

3D printing use has been expanding in recent years. From art to science, this growing industrial revolution aided in making many new developments, including two ones that may have helped the medical industry. Reconstructed ears from a 3D printer Ear reconstruction is one of the hardest surgeries to do. The problem is making the ear. You can thank the ear cartilage's uniqueness for that. It needs to be soft and flexible, but still have strength and form. Any replacements done often look unnatural and do not provide a good redirection of sound to the eardrum. Scientists have been exploring ways to better provide children born with congenital deformity microtia or people who suffered some type of ear loss with real, quality ears. A team at Cornell University may have found just that. Professor Lawrence Bonassar and his colleagues found a way to make ears more lifelike. He began his research with his 5-year-old twin daughters. They first scanned the girls' ears to create a digital mold. A 3D printer then printed it. A gel made of living cells was injected into the mold. The ears were finally removed and some trimming took place. The quickness itself may be one of the best parts of this process. It takes less than 48 hours to fully complete the ear.

The molding, half a day, and the printing, a full day, are the culprits behind the time. Either way the 2 days is a far better time than traditional practices where rib cartilage is used to make fake ears. The traditional way also does not create a custom ear for the individual which many have commented on. Surgeons' main worry is whether the body will accept the new part. A rejection could cause an internal battle inside the recipient and another surgery will need to be scheduled. No one wants that. With the 3d printer being added into the equation, the research team at Cornell can now focus on growing human ear cartilage cells. They have custom molds so there is no need to remove any other rib cartilage from the patient or use some type of foam. If the cells can be made similar to the body's previous ones, then it will a rejection of the ear will be less likely. This is a great advance in science but do not expect real-looking fake ears any time soon. The Cornell group needs to do some experimentation and if all goes well, we could see a release in 3 years. A more important organ is printed Your heart has one of the hardest jobs in your body; it beats all-day, every day. Any sort of stoppage will result total body shutdown.

Electrical current provides the stimulation the heart needs to contract. If there is any type of irreparable damage to the heart and it stops, doctors will replace it with an artificial one. A new "artificial heart" has been recently designed and printed. OK the print isn't really a heart for a human. It's more or a robotic heart. Artists and designers can use the heart, a biologically-driven actuator, to simulate a pulse in an inanimate object. Peter Walters and his colleagues from the University of the West of England in Bristol, UK invented the device. They used the photo-polymer jetting technique developed by Stratasys. Walters added yeast to provide the electricity needed to cause the beat. Maybe a real artificial heart could be printed one of these days. A brave new world Hopefully other professors or people in general will be inspired by the two creations. Either you can look at the medical side and try to emulate current procedures or you can look at it from a new use of the printer. Let's try to make as many 3D printing achievements as we can in the upcoming years to make the world a better place.
