The denture, which he disinfects the gums, and printed on a 3D printer

Prostheses with pre-loaded medicines will help effectively and continuously to decontaminate the oral cavity.

Nearly two-thirds of people who wear dentures are faced with an unpleasant problem of infections that cause redness, swelling of the mouth, unpleasant smell and inflammation, sometimes accompanied by fever.

This kind of mucosal lesions called thrush and treated, usually with antifungal drugs and antiseptic solutions for rinsing. In addition, people have to constantly clean and disinfect the dentures.

However, there is an option much easier. A team from the University of new York at Buffalo have presented the first set of teeth, is provided with a drug delivery system. And create a prosthesis that will disinfect the gums was helped by the three-dimensional printing technology.

According to scientists, these prostheses are created individually, based on the impression of the jaw of the patient. Material for this is polymethyl methacrylate – acrylic resin, which is often used in dentistry.

Thus in the lower part of the prosthesis (which is adjacent directly to the gums) are microscopic capsules of a biodegradable polyester called polycaprolactone. These pods are filled with an antifungal drug – amphotericin B.

In the printing process, the capsule protects the drug from heat, and then, in the process of wearing a prosthesis, it collapses and the drug is released.

It is clarified that, depending on the condition of the mouth and immunity of the patient, the prosthesis can be download you need a number of capsules with a drug. The most appropriate "pave" capsules one layer. The researchers experimented with one, five and ten layers of microcapsules. It turned out that the last two were not so effective: the more additional layers, the worse the porous structure passed the released drug.

The team also tested their design strength. Method of bending test (flexural strength testing) showed that, compared with conventional dentures, the printing strength is below 35%, however, none of the samples during the tests is not broken and not cracked.

As the authors note, innovative methods will help patients to save a lot of time and money. But, most importantly, the development will effectively and continuously to decontaminate the mouth and prevent the development of dangerous diseases. This is especially important for elderly and disabled people who have limited movements or are not able to conduct regular preventative treatment with conventional dentures.

In addition, the production of classical dental prosthesis may take from several days to several weeks, while a 3D printer will print its equivalent faster.

However, the work is not yet complete: the engineers plan to enhance the mechanical strength of the printed prostheses, and also to test different methods of recovery in case of failure.

By the way, according to experts, for the same technology to create other medical devices loaded with drugs. This can be, for example, plaster bandages, prostheses or stents (scaffolds for regulation of the width of a hollow organ or part of the artery, bowel, esophagus, etc.).

Learn more about dentures a new generation is covered in the article, which is presented in the publication Materials Today Communications.

By the way, earlier it was mysoulmate about other interesting solutions in the field of dentistry. For example, a new peptide toothpaste that restores enamel and heal cavities in teeth, as well as on the nanoparticles, which will replace the dentists scalpels.

Astronomers tell about geomagnetic situation for May holidays

Yandex.Direct

In May, 2 magnetic storms are expected, however, for May holidays no changes in the geomagnetic situation are expected.

This was reported by the Laboratory of X-ray Astronomy of the Sun of the Lebedev Physical Institute of the Russian Academy of Sciences (FIAN).

In general, solar activity in May will be weakened. Thus, from May 1 to May 8, from May 9 to May 16 and from May 29 to May 31, no changes in the geomagnetic situation are expected.

“The probability of formation of large centers of activity on the Sun is only 5%, which with a high probability means almost complete absence of solar flares,” the Laboratory said.

Two magnetic storms can occur on May 7-8 and May 17-18 – during these periods the Earth will pass through the solar wind regions.

How successful were the Galaxy S9 and S9 +. Answer in figures

Samsung introduced a new generation of flagships in late February. Galaxy S9 and S9 + were protected against water, advanced cameras with adjustable iris, slow motion pictures and AR Emoji, which could be much better. Smartphones are sold for more than a month, so you can sum up the result of their popularity.

Data on sales of Galaxy S9 and S9 + were shared by Canalys employees. The new flagships did not set a record, but they did not lose to the previous generation either. It is reported Phone Arena.

Within a month, Samsung sold 8 million Galaxy S9 and Galaxy S9 +. The figure coincides with the results of the S8 line and lags behind the popularity of the flagships in 2016. For the same period, Samsung sold more than 9 million Galaxy S7 and Galaxy S7 edge.

At the same time, analysts predict an improvement in the situation. According to their version, within a year Samsung will sell 45 million Galaxy S9 and S9 +. This will overtake S8 and S8 + at least 4 million devices.

Thus, the Galaxy S9 did not become the leader of the domestic race of Samsung. Think about the reasons for this situation can be in the official telegram-chat AndroidInsider.

Rocketplanes for science and battles: Soviet orbital fighter

Soviet rocketplanes and cosmoplanes were to not only explore the depths of space and fly to other planets, but also to fight with the probable enemy in the orbital and suborbital space.

These projects have largely outpaced their time and have not been implemented, but documents from declassified archives today allow us to appreciate the courage and originality of Russian design ideas.

At the turn of the 1950s-1960s, when cosmonautics was taking its first steps, there were more questions than answers in the development of near-Earth space. One of the most serious problems to be solved by designers was the safe return of astronauts from orbit.

Descent along the ballistic trajectory gave an overload of about 10 g, which created enormous loads on the human body. As is now known, the final part of the flight Yuri Gagarin performed outside the descent vehicle. The first cosmonaut was ordered at a certain altitude to leave the ball of the “East” and land on a parachute – for fear that he could not bear the overload of ballistic descent.

Do not fall, but fly

The rocket system of the “Kozhukh” system

The rocket-fighter is made on combined technology. Thermal protective casing in the form of a “capsule” includes a winged descent vehicle. The height of combat use is 300-1900 km. The starting weight is 1200 kg. It is put into orbit by the UR-500 missile. On board are 8 “space-to-space” shells. Before descent from the orbit, the combat unit separates, after passing through the main heat flows, a heat-shielding shell is fired and the apparatus with the cosmonaut on board lands on the aircraft type.

As practice has shown, the trained organism is able to withstand these overloads. But let’s not forget that cosmonautics in the midst of the Cold War developed primarily with an eye to combat use. A likely scenario of a global conflict could require simultaneously a large number of pilots of military spacecraft, and there would simply not be enough time to carefully select and train cosmonauts. It was necessary to develop a more gentle way of descent from orbit and landing.

One such method is the creation of a descent vehicle with a planning capability, or with aerodynamic quality. The idea of ​​a planning spacecraft, or a rocketplane, was widely used and was the basis of projects developed both in the USSR and in the USA (for example, the Dyna Soar project).

The advantage of the device with aerodynamic quality is not only in reducing overloads, but also in the ability to maneuver during descent, which provides a more accurate landing. The development of this topic also opened the possibility of creating maneuvering warheads and orbital / suborbital bombers, at hypersonic speeds and high altitudes overcoming enemy air defenses.

Rocketplanes for science and battles: Soviet orbital fighter (10 photos)Rocketplanes for science and battles: Soviet orbital fighter

A lot of work on the topics “Rocketplanes” and “Kosmoplans” was carried out in the early 1960s at the Joint Design Bureau 52 (now FSUE “NPO Mashinostroenia”), founded and headed by the then outstanding Soviet designer VN. Man. In the description of the draft design stored in the OKB-52 archive, the following definition is given: “A rocketplane is a reusable spacecraft capable of flying in outer space that can reach orbital I and II cosmic flight speeds, using for control of the flight path as gas-dynamic , and aerodynamic forces and capable of making significant maneuvers in space and atmosphere and landing at a given point on the earth’s surface. “

The projected missileplanes were divided into two functional groups: military and research. The group of military rocketplanes was divided into high-orbit and low-orbit.

High-orbit rocketplanes were to operate in orbits with altitudes of 150-5000 km and be used to intercept, identify and destroy space targets (satellites and military stations), defeat strategically important land and sea targets, conduct operational and strategic reconnaissance from space and organize an early warning system PRO of the country on the launch of enemy ballistic missiles.

Low-orbital rocketplanes were supposed to be used at altitudes of 50-80 km, where at hypersonic flight speeds it is still possible to effectively use aerodynamic forces to control the flight path. According to the design of the designers, high speed and the ability to maneuver widely with orbits gave the low-orbital missileplane the advantage of a small vulnerability from the enemy’s ABM. Such vehicles were intended for use as bombers and reconnaissance vehicles, and also as a special vehicle.

After passing through the main heat flows, the thermal protection container (casing) continues to move along its own trajectory, characteristic of the “capsule” with low AK. The sketch shows the return scheme of the spaceplane AK-3. Before descending to the ground, the unit shoots a block with a marching engine.

If we consider that according to one of the projects in the spaceplane the use of a nuclear engine was supposed (the nuclear reactor heats hydrogen, which acts as a working fluid and, expanding, creates a reactive thrust), it is obvious that the designers faced the problem of how to prevent the reactor from dropping to Earth.

It was believed that the problem can be solved by driving a block of propulsion engines into outer space due to its own thrust. After separation of the engine, the ship opens a braking hub made of thin plates of refractory metals. The umbrella is designed to remove heat from the compressed air flowing around the ship. Then the thermo-casing is fired, and the winged descent vehicle leaves for the aircraft landing.

The diagram clearly shows the entire process of the descent of the spaceplane from near-earth orbit, from the separation of the engine to the landing of the cruise vehicle.

The manned orbiter fighter of satellites consists of a returnable to the ground of the planning device of the “cone” system and a dropping combat compartment. The body of the planning part consists of three hermetic compartments: bow, cockpit, steering. The starting weight is 14 tons. It is put into orbit by the UR-500 missile. The height of combat use is up to 3000 km. The control room and power supplies are located in the instrument compartment. The cabin has a two-channel optical system for target and orientation selection, a control panel, a pilot-cosmonaut power supply system, a radio telephone line “Zarya”, a television camera.

The cabin has two side windows for visual observation of outer space and a hatch for landing the pilot-cosmonaut.

In the combat compartment there are 12 “space-to-space” shells, a propulsion system with rigid and soft stabilization systems, an antenna and radar equipment. Type of landing – parachute.

Since the “space-to-space” shells were located in the stern, the pilot was aiming at the target with the help of a special optical system that allows to look “behind the back”.

May 10, 1960 representatives of the OKB-52, headed by V.N. The people were summoned to the Kremlin for a report. The report was attended by NS. Khrushchev, as well as supervising at the time the defense industry LI. Brezhnev, USSR Defense Minister R.Ya. Malinovsky, chairman of the military-industrial commission DF. Ustinov.

Chelomey outlined the proposals of OKB-52 on the creation of interplanetary and near-Earth space vehicles and accelerating rockets for them. The proposals included the development of a spaceplane for a flight to Mars and Venus, which, upon return, could land at a given point on the Earth, as well as the creation of manned and unmanned rocketplanes for near-Earth flights.

After 11 days, the report was presented at a meeting of the Scientific and Technical Council of the State Committee of the USSR Council of Ministers for Aviation Technology, which was attended by leading Soviet aircraft designers – Tupolev, Myasishchev, Mikoyan, Lyulka and others. And on June 23, the resolution of the Central Committee of the CPSU and the Council of Ministers of the USSR was issued with the instruction of OKB-52 to develop space vehicles based on the proposals.

At the same time, the need for descent from the orbit on the wing became the subject of serious discussions in the engineering and design environment. Whereas V.N. Chelomey believed that behind the winged descent vehicles the future, representatives of other design bureaux and institutions showed great caution in this matter. V.A. Polyachenko remembers the discussion that took place between Chelomey and Korolev at a meeting with Ustinov. Korolev acknowledged that the descent vehicle, built on a winged scheme, can be indispensable, for example, when landing on Mars.

But if we are talking about near-Earth flights, then “it is expensive to drag wings into space.”

OKB-52 developed many variants of winged vehicles, however, due to the difficulties in creating heat protection, this direction was the least developed.

The sketches include a missile with a detachable warhead, as well as suborbital winged aircraft for flights of 8,000 km and 40,000 km.

According to the sketch, such suborbital rocketplanes are taken to the flight path with the help of the first stage, which starts from the airfield by airplane type, and then independently returns to the place of basing. Suborbital missiles were designed in particular to transport personnel and cargo to virtually anywhere in the world.

Their other purpose is scouts and bombers.

The Fate of a Dream

Rocketplanes for science and battles: Soviet orbital fighter (10 photos)The Fate of a Dream

But 20 years later, with the first space shuttle Columbia, it was proven that descent from orbit using aerodynamic forces has the right to exist. We returned to the idea of ​​winged descent in the USSR, creating the “Energy-Buran” system as a result. But in the early 1960s, the development of OKB-52 was much ahead of its time and could not be implemented on the basis of the then technologies. March 21, 1963 OKB-52 made a test of the M-12, which was a cone with tail boom. During the tests the device collapsed.

One of the possible causes of failure is the complete combustion of rudders in dense layers of the atmosphere. By the mid-1960s, the theme of spaceplanes and rocket planes was virtually closed.

However, there is no reason to consider it a “dead-end branch”. The performed calculations in the field of aerodynamics and thermodynamics became a logical step for the OKB-52 on the way to the creation of devices that actually worked in orbit, for example, the orbital manned military station Almaz, the progenitor of Soviet orbital stations.

Work on a rocket-carrier for rocket-propelled vehicles led to the creation of a powerful UR-500, better known as the “Proton” and still faithfully serving Russian and world cosmonautics. OKB-52 returned to the theme of the winged descent in the 1970s, having started designing the LCS (light space aircraft), in fact a two-seater “shuttle”.

The Soviet leadership made a choice in favor of a heavy and roomy Burana.

Scientists have made the top-8 space threats to humanity

Scientists have made the top-8 space threats to humanity

Scientists have made a rating of the eight most dangerous for life on Earth, space phenomena.

The first place in the top 8 space threats to mankind is blown up by the explosion of the Sun, which will destroy our planet. However, according to experts’ forecasts, this will happen only after 5 billion years – there is nothing to be afraid of today’s man.

On the second place on the danger to life on Earth – the descent of our planet from its orbit. The Earth will begin to move away from the Sun, as a result of which a new ice age will come.

The third place is occupied by asteroids. According to one hypothesis, it is because of them that dinosaurs disappeared.

Another danger is the wandering black holes, which in our galaxy there are about 10 million. This phenomenon can absorb the Earth as it approaches its orbit.

In the fifth place – gamma-ray bursts that will occur after the transformation of a dying star in the constellation of Sagittarius into a supernova. Such radiation can destroy all life on Earth, but it will happen in the very distant future – in the next few hundred thousand years.

The last three places in the rating are occupied by the collision of the Earth with another planet (this is how the Earth and the Moon formed about 4.5 billion years ago), aliens and comets.

Dentures taught to adapt to “touch” under human movement

Dentures taught to adapt to "touch" under human movementAadeel Akhtar et al. / Science Robotics, 2018

People who use prostheses with a “touch” — that is, able to convey a sense of touch using electrical stimulation of the skin, at a disadvantage due to the fact that this feedback not only depends on touch, but also on the electrical conductivity of the skin and the characteristics of the contacts. American scientists have developed an algorithm that continuously monitors contact of the electrodes and adjusts the stimulation level so that the sensitivity remained at the same level, according to an article published in the journal Science Robotics.

To fully compensate the loss of the hand is extremely important that the prosthesis could not just freely make complex movements, but also to give the person feedback. There are already prosthetics that can convey sensation through an implanted or applied to the arm electrodes with electrical pulses corresponding to touches of the prosthesis. The prostheses attach to the skin electrodes are more comfortable, but they have a significant disadvantage — perceived feedback from the prosthesis depends on the contact between the electrodes and the skin, and can vary in case of partial disconnection of the electrode or sweating.

A group of scientists from the University of Illinois at Urbana-Champaign under the guidance of Timothy Bretl (Timothy Bretl) in 2014 developed a model describing the dependence of the intensity of electrical stimulation required to maintain stable sensitivity, characteristics of the electrodes are in contact with the skin. In particular, it implies that energy of the stimulating pulse and the phase of the charge (the product of the current on time pulse) are linearly dependent on the contact impedance between electrodes and skin at a constant sensitivity level.

Dentures taught to adapt to "touch" under human movement

Diagram of nerve stimulation electrodes

Now scientists have experimentally tested the model on the volunteers and also created an algorithm that allows to maintain a constant level of perceived feedback from the prosthesis, changing the characteristics of the stimulating pulses. During the first experiment on 10 volunteers, scientists change the characteristics of the contact electrodes and, since the current density is increased, the stimulation level is increased. Volunteers adjust the current level so that the feeling matched the original. Thus, scientists have obtained the dependence between the intensity of the pulse, the level of contact and sensitivity among different research participants, and was able to confirm his model. The authors claim that their model describe the experimental data better than models from other studies.

After this, the researchers created an algorithm to automatically adjust the level of stimulation under the contact between the electrodes and the skin, which may vary in everyday movements. The researchers tested its effectiveness in two patients with amputated below the elbow of the right arm and prostheses that convey sensations from the fingers touch to the objects. They were asked to perform three exercises, during which the hands are constantly moving: climbing stairs with railings, nailing and exercise on the elliptical trainer. After exercise, subjects were told that sensitivity is lost at the electrodes that are not managed by the algorithm, and on the contrary preserved from those through which the stimulation adjusted by the algorithm.

In 2016 the American scientists have created a prosthetic arm and a neural interface that allowed a paralyzed man to handle the items. Unlike many prosthetic arms, it connects not to the peripheral nerves of the hand, but directly to the cortical area of the brain responsible for tactile sensitivity in the hand.

Experts: You can hack your computer through PDF files

Experts found a new vulnerability in the computer security system. It turns out that you can hack a PC through PDF-files, having registered in them the function of remote access.

Experts: You can hack your computer through PDF files

Experts believe that hackers use PDF files to break into computers. As an experiment, specialists created a file with remote access and external insert functions. When you open the document, algorithms without the user’s knowledge send a request to a remote SMB server, which allows you to enable authentication using NTLM hashes. Thus, the hacker accesses the user information through the server.

Experts report that often cybercriminals use Windows programs to send files containing SMB requests. In early 2018, hackers used a Word file that, without the knowledge of the user, downloaded malicious software and sent the user’s passwords to the server. Now the danger is represented by PDF files with Go To functions Remote and Go To Embedded.

Dmitry Rogozin outlines the timing of a new breakthrough in cosmonautics

In the summer of this year, the second stage of reforming the rocket and space industry will begin. This was recently announced by Deputy Prime Minister Dmitry Rogozin, who oversees the military and space industry in the government

At the first stage there was a reorganization of the enterprises of the industry, which now are subordinated to a single center in the person of the state corporation "Roskosmos". Now, Rogozin explained, "Roscosmos" it is necessary to determine the unified technical policy of the structures included in it, and not simply to manage their shares.

Single center

In recent years, according to experts, domestic space exploration is in an upward trend. Promising projects are being actively implemented that confirm the status of Russia as the leading space power. In particular, a whole family of launch vehicles is being developed, such as "Angara", and a range of missiles "Union". In the arsenal – several dozen modern space vehicles for both scientific and military purposes. The constellations of satellites for remote sensing of the Earth and for communications have been formed. A full-fledged satellite navigation system GLONASS has been built and is functioning stably. In many respects this is connected with the improvement of the quality of the scientific and technical base. Analysts come to life in the industry associated with the appointment of Dmitry Rogozin curator of space programs. It is he who is considered the initiator of large-scale transformations in the industry. Assessing the results of the first stage of space reforms, experts first of all note the fact that Roskosmos has become an independent structure responsible for the execution of state orders. The conclusion is confirmed by the results of the work of the state corporation for 2017: 20 successful launches, including commercial launches from spaceports "Baikonur", "Plesetsk" and from the Guiana Space Center (Kuru); 4 launches of transport manned ships "MS Union" and 3 launches of transport cargo ships "Progress MC" under the ISS program; launch of spacecraft "Canopus-B-IR", for the first time equipped with domestic production equipment, which makes it possible to detect even small fires on the Earth’s surface. In addition, last year it was possible to reduce the accident rate of launch failure by 0.2% compared to 2016 and by 2.1% compared to 2015.

Mars is getting closer

Dmitry Rogozin outlines the timing of a new breakthrough in cosmonautics

The second stage of the reform of the space industry, in fact, has already begun. In particular, it was announced about the plans for forming on the basis of the RKK "Energy" Holding, which will continue to create a superheavy carrier rocket. Personally, the president of Russia personally announced her tests. According to Vladimir Putin, the missile will be able to deliver to the low Earth orbit from 80 to 140 tons of payload. "The first test is planned in 10 years", – assured the president. At the end of October 2018, the RKK "Energy" should submit a draft of the missile. For these purposes, Roskosmos is going to allocate 1.6 billion rubles. At the same time, a special launch complex will be created at the Vostochny Spaceport. Experts believe that if the project is successfully implemented, Russia will take the leading position in the world in the exploration of outer space, since the space truck will provide flights to Mars, Jupiter and the Moon. The volume of useful cargo for delivery to the Earth’s satellite will be 20 tons, and in the future, 27 tons. The lunar program is designed until 2030. According to Dmitry Rogozin, "we are going to send the station in 2019 "Luna-25", which is a "small landing module". "Further stations will follow, including those that will work in the Moon’s orbit, a landing module that will sink to the ground, enter the layer of regolith-lunar soil", – the curator of the program explained. In 2022, Russian cosmonauts are scheduled to fly to the Moon as part of an international crew.

Leadership will not be given up

The Vice Prime Minister does not doubt the successes of Russian space programs. He recalled that the ongoing reform – "it is the consolidation of the entire industry, the elimination of parallelism, the creation of equal conditions for public and private companies that can participate in space activities, and this development of international programs". For his part, Rogozin assured that all key Roskosmos enterprises can continue to rely on government support. In addition, the industry itself earns money for its development, for example, the export of Russian jet engines for space purposes. According to the deputy chairman of the government, the sale of engines developed in 1970-1990 allows Russia to build their modern analogues – including the RD-191 engine, as well as modernize old ones. Rogozin cited the example of RD-171, which "will be used to create a medium-range missile "Soyuz-5", the same engines in a more modernized form will be used to create a superheavy rocket". International cooperation is not hindered even by sanctions. So, Roskosmos participates in a large-scale English project OneWeb to put into orbit about 700 satellites to provide high-speed Internet. Last year, the corporation even signed an agreement on the creation of a joint venture with the British. Therefore, everything that Western publications write about "the end of Russian space", Dmitry Rogozin calls "stupidities" and yet does not see in the world worthy competitors. "We are not going to give you anything. Dreaming", – he said recently. At the same time, the Deputy Prime Minister stressed that Russia, in order to maintain its leadership, is ready for any challenges in space.
