Pressure Regulating Valve or commonly abbreviated to PRV is a component of hydraulic or pneumatic system that serves to adjust the fluid pressure of the high pressure system resources (such as pumps, compressors, or reservoir) to the low-pressure system. PRV is always in charge of maintaining fluid pressure value is lower than its supply pressure, therefore the pressure of the fluid before passing the PRV will always be greater than the pressure after passing through PRV. It can be said PRV serves to lower fluid pressure so that it meets system requirements specification, or also for the security and safety of use.
Broadly speaking there are two types of PRV when seen from operational systems, namely single stage and two-stage pressure regulator. The above picture illustrates a PRV system with only a single stage pressure regulator. The image appears on several major components such PRV inlet and outlet pressure gauge, diaphragm membrane, spring, poppet valve, as well as a lever to adjust the set point PRV working pressure. Pressure gauge serves as a good appointment fluid pressure value on the source side and the output side pressure of the PRV. Diaphragm function is to create a flexible working space in the PRV capable of changing volume. Two springs on the PRV system serves to generate pressure equilibrium, while Poppet valve serves to open and close the fluid flow.
The most fundamental difference of PRV with a two-stage pressure regulator as compared to the previous system is the two-stage system was used spring and diaphragm membrane that is more to create an equilibrium in the PRV chamber (chamber). At the time of the fluid pressure in the outlet room to fall, then spring 1 will suppress the diaphragm and poppet valve 1 so that a higher pressure fluid in the chamber will go into the outlet chamber. When the fluid pressure chamber drops because they have got into the room outlet, then the same process occurs in the spring 4 which will encourage the poppet valve 2 so that a higher pressure fluid went into the chamber. When the fluid pressure outlet is in conformity with the pressure set point was, the spring system will form an equilibrium so that both poppet valve will be fully closed.
A revolution in technology alternative back unsolved. A group of mechanical and Australian scientists have announced that they will soon be marketing a new technology in producing solar panels. The technology they create does not require a complicated way to produce solar panels, all they need is a printer! Yes, a printing machine that will quickly and cheaply can print solar panels onto the surface of any object, especially plastic! Naturally this innovation will decisively, sooner or later, push down the price of conventional solar panels are quite expensive because the manufacturing process is more complicated.
Research conducted by a combination of mechanical and scientists of this has been done down at least the last few years. One senior researcher mentioned that this new technology can easily print solar panels directly on the sheet of plastic or other material. In fact, it can also be printed directly onto electronic equipment sorts of laptops and smartphones, so they get a renewable energy source at any time.
We print it out on a plastic sheet is approximately equal to the process of printing banknotes. Connect it with other electronic equipment as well as easy as installing the battery. It’s very cheap! The interface is also quite different from the conventional silicon solar panels. He explained in more detail that the printed solar panels will appear transparent, thus making it very suitable to be applied to building homes and buildings.
Our next task is to improve the efficiency of the panel. We should be able to create a ‘printing ink’ which is able to absorb more solar energy. We are sure to be able to do in the next few years.
SpaceX, a private company engaged in the assembly of the spacecraft is planning to send a spacecraft named Red Dragon to Mars in early 2018. The company owned by Elon Musk has said openly will carry out further Mars exploration involving humans and no longer using robots someday. Although it has been stated that the company did not specify how many spacecraft that will be sent to Mars associated with this mission.
The spacecraft will be flown in from SpaceX to Mars, using the booster rocket Falcon Heavy. Falcon Heavy rocket is a newer version than the previous version of the Falcon 9 rocket that will first be tested for a launch capsule heading to Mars with no humans involved in it. When launching the capsule with heavy payloads landed well on Mars, then SpaceX will launch involving humans in it. In addition, if SpaceX is able to do that, then SpaceX was the first private airlines were able to land a spacecraft on another planet. The aircraft also will be used as a residence by the astronauts who went to Mars. SpaceX company also said that the Red Dragon is a spacecraft weighing 6,000 kg before sliding out of the earth. Then when it is outside the Earth’s atmosphere, some parts like a rocket booster will be released from the main spacecraft. Then one by one the other parts that are not needed will be released until finally landing on Mars successfully done so only in the form of capsules. At the time of landing is successful, the capsule has a weight of 3000 kg.
The landing propulsion machinery is a machine that allows landings efficiently to deliver cargo in bulk to the surface of Mars. This is one way that NASA still does not know how to do it. If not using the engine driving the landing capsule is definitely potentially suffered severe damage. It is caused by a very different atmosphere between the Earth possessed with Mars. The atmosphere on Earth thicker, thus allowing the capsule to be crash landed more slowly. Mars has only a much thinner atmosphere than Earth, so that the capsule would have the potential to experience a violent collision with the surface of Mars. To prevent conflicts, the driving engine landings can be controlled very necessary. Read more
In the future all electronic equipment will be designed to be thinner and thinner. There are even some electronics to be designed to be more flexible. The researchers made that all possible. The researchers have managed to create a display that is named Organic Light Emitting Diode (OLED).This display is very thin, flexible, and has a protective layer, thus enabling creation of electronic skin (e-skin) to detect the blood oxygen level, heart rate sensors e-skin for athletes and other applications.
OLED invention is intended to integrate electronic devices with a human body to increase or restore the function of the body, so in other words to be used as a biomedical application. The integration of electronic devices with a human body it is becoming a trend researchers around the world.In particular, the electronics that can be used must be thin and flexible to minimize the impact where they attach to the body. However, most of the devices developed so far require millimeter thickness and made of materials such as glass or plastic substrate with limited flexibility. Meanwhile, usually organic devices with micrometer-scale thin flexible yet stable enough to survive in the open air.
This research could also be directed towards the manufacture of mobile phones too. The advent of mobile phones have changed the way we communicate.While this communication tool designed to get smaller and smaller over time. But sometimes that is not practical is that device shall we take to use it. Would not it be more practical to use the device at all times attached to the body and can even show emotion or level of stress or anxiety us. Besides not having to carry the device at all times, at some point it might be to improve the way we interact with the people around us.

Remember you will Hoverboard? Skateboard without wheels that floated above the ground? Or also Water Flyboard, other extreme sports. Not yet old extreme sport is booming, there are already competitors are even crazier. Introduce Flyboard Air, a new extreme sport which is currently still in the testing phase.
Air Flyboard if observed at a glance may work similar to Water Flyboard. But you need to know that Flyboard water use turbojet engine to produce lift that is great. If Water Flyboard very limited with the water suction hose length, then Flyboard Water may only be limited by one thing, the courage of the riders. Yes, the flying apparatus is claimed to be able to fly up to 10,000 feet or the equivalent of more than 3,000 meters!
The use of a jet engine makes Flyboard Air works similar to an airplane. Needed space for the fuel, combustion air, and that certainly is the stability of the rider. It appears also sport this new tool more widely used on the surface of the water, I suspect this was done because the hot air in the combustion engine Flyboard jet is definitely more secure if it is disposed on the surface of the water rather than on land.

The pacemaker is one of the emergency safety equipment. While this tool is very reliable for any emergency medical condition but this tool does have some limitations, including the failure of its parts and the risk of infection by viruses that come from the patient’sbody. Pacemakers must also undergo regular checking process and must be replaced periodically.Based on the background of this issue, a group of scientists trying to create a biological pacemaker that is expected to replace the electronic pacemaker role in the future.
One of the researchers, the biological pacemaker consists of electrically active cells that can be functionally integrated with the heart and give a naturalheart rate without requiring the presence of foreigners in the heart of the hardware.Theoretically, the approach to create a biological pacemaker is to transform stem cells into a special pacemaker commonly found in the sinoatrial node of the heart.Cells specialized pacemaker successfully created will then be transplanted into the patient’s heart to restore a normal heartbeat function. Another approach that can be used is by changing other cells in the heart, such as cells in the fibroblasts (connective tissue of the heart) and turn them into pacemaker cells.
So far the research is still tested on animals but has not really produced anything considered to be applied in human clinical therapy. Researchers still need to understand the mechanisms of control and maintenance of pacemaker cells that have been produced.In addition, the researchers found it necessary to develop a method of cell transplantation pacemaker in certain parts of the heart. Biological pacemaker should really be prepared in such a way with the higheststandards. Due to the failure of the pacemaker even for a moment can be very harmful to the patient’s life.

Sure military world is in need of technology that can make them invisible. Technology like this is in the development stage and answer that allows to realize it is a nano-technology. The robe has a total thickness of only 80 nanometers. Composed of magnesium fluoride coating of 50 nano meters, the surface is covered by nanoantena made of very thin gold block 30 nano meters thick and have a variety of sizes. Nanoantena is used to bend the light, so that objects that are covered by this cloak will not be visible. This robe can adjust to the environment. That is just one of the nanotechnology developed for military purposes incognito.
Nanotechnology both created for the purpose of the military is a robot chameleon disguises. The chameleon skin color trying to adjust the color in the environment. Technology like this can be used by the military to disguise with their surroundings. This discovery will continue to be developed, so that one day can be fused perfectly to the surrounding environment. Nanotechnology could one day be blended at vest military defense.
The chameleon robot can produce a color change by utilizing the interaction between nano-scale structures in the electric field. The skin of the robot consists of sheets of glass edge of each sheet of glass there are some holes. Each hole has a diameter of 50 nm, and in it is inserted gold nano. When light hits the gold nano structure, it will make little bumpy electrons, determines how much light is reflected, how much is absorbed, causing the sheets of glass become discolored. But the lack of a robotic chameleon that can only detect basic colors like red, green, and blue, because of the limited ability of current sensors for detecting color. Read more

Space is a secret that is always interesting to learn. We all know that the outside world we live in is a lot of planets that are part of our solar system. We know of the existence of other planets but do not know what the planet. Starting from Albert Einstein’s theory of relativity theory about the speed of light and is supported by the theories advanced as Warp theory of space-time, the curiosity of the room space will increase. Therefore, the scientists plan to create the most sophisticated spacecraft that can realize the desire to explore space. Spacecraft embodiment is described in the epic science fiction that explore space.
The following spacecraft is a spacecraft from time to time and is the best design of the future, among other things:
- USS Enterprise NX-01 is an aircraft that was launched early in 2151 in the Star Trek prequel. This aircraft is a spaceship Earth with speeds exceeding the speed of light, Warp 5.
