Published: February 2019

INTRODUCTION: High frequency jet (HFJV) and oscillatory (HFOV) ventilation were used to rescue newborns with congenital diaphragmatic hernia (CDH), who failed conventional mechanical ventilation (CV). Changes in ventilator settings and pulmonary gas exchange were evaluated following transition to high frequency ventilation (HFV). METHODS: Records of patients with CDH rescued with HFV prior to surgical intervention between 2006 and 2015 were reviewed. Mean airway pressure (Pāw) and arterial blood gases during CV and those obtained within the first hour of HFV were compared. A composite repeated measure analysis was performed to evaluate longitudinal and intergroup variances. RESULTS: Twenty-seven patients were rescued from CV, 16 by HFJV and 11 by HFOV. The two groups had similar gestational ages and birth weights. Prior to HFV, both groups had similar Pāw, PaCO2, FiO2 and PaO2. HFV was associated with a significant improvement in ventilation, and the rate of decrease of PaCO2 was no different between groups. There was a significantly higher increase in Pāw increase with HFOV compared to HFJV. CONCLUSIONS: In newborns with CDH rescued with HFV, ventilation improved but Pāw was significantly lower in patients supported with HFJV compared to HFOV.

The background of this researchwas by the fact that the role of youth in national development was still low becauseMuslims youth seemslike losing their way, experiencing stagnation of creativity, getting out of their natural rotation, and losing their role models in their lives.At this time many of the Muslims youth are ensnared by the globalization virus that eliminates the extraordinary youth figure throughout the history of Islam. Even that disseminated artists who are product of temporal world. The impact of losing role modelsis can be imitating bad Western culture.Start from hedonism, wasting money, dating. This research find the results if want to build the people and seek the return of the glory of Islam, Muslim youth will take that role. Youth's active role as a moral force is realized by developing ethical and moral aspects in acting on every dimension of youth life, strengthening faith and piety and mental-spiritual endurance, and increasing legal awareness. One day glory ofislam was an accumulative work between generations, the triumph of Muslims will never stand only with the blood of one young man, not only with the tears of a young man, not only with the idea of one young man, therefore what is needed by Muslims in the future was not a young man, but a youth union and movement that initiates the unity of Muslims

Introduction: Ionic liquids (ILs) have become a prospective candidate to replace the conventional electrolytes based on the volatile organic-solvents in lithium-ion batteries. However, the drawbacks of high viscosity and low ionic conductivity have restricted the high rate capacity and energy density in practical batteries. With the aims to resolve these problems and design a safe electrolytes with high electrochemical stability, mixtures of ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl) imide (EMITFSI) with different amounts of ethylene carbonate (EC) was prepared and characterized as electrolytes for Li-ion batteries.
Methods: In this work, we investigated four factors to demonstrate the performance of EMITFSI as electrolytes for Li-ion batteries. These factors include: thermal properties of mixed electrolytes (Mettler Toledo DSC1 Star -DSC, Q500-TGA), Conductivity (HP- AC impedance spectroscopy), Viscosity (Ostwald viscometer CANNON) and electrochemical window (cyclic voltammetry-MGP2 Biologic Instrument). All experiments were repeated three times with the exception of TGA-DSC methods.
Results: The study indicated that 20 % wt. ethylene carbonate (EC) when mixed with EMITFSI could significantly decrease the electrolyte viscosity while improving ionic conductivity and maintain similar electrochemical stability as pure ionic liquid. Lithium diffusion coefficient of mixed electrolytes was lower than commercial electrolytes based on conventional solvents, however, the thermal stability was enhanced.
Conclusion: EMITFSI can be used to replace conventional carbonate-based liquids as a high-performance electrolyte for Li-ion batteries.

A non-relational database was developed at JSC Element for the recording operating parameters of GTE and systems during the test flight. The database is modernized version of one which is a part of the GTE test bench. The purpose of the database is the recording and analysis of GTE and systems operating parameters. The parameters are measured (collected) with multiple frequencies in range from fractions of Hz to tens of kHz. Number of recorded operating parameters is 1000+. Correspondingly the database file is huge and may reach tens of Gbytes. Number of different parameters recording frequencies is 10…20 (e.g. 20 parameters – 10 Hz, 30 parameters – 50 Hz, 20 parameters – 10000 Hz). Data reading and chart displaying should be possible as right after the test flight as just in parallel with database recording. There should be no significant delays in getting the data displayed independently from the zoom level chosen. The user should see the result in time comparable with time of the displayed chart perception making the user feel the smooth application operating and not interrupting the process of test flight result comprehension – main purpose of our product.However, min-max chart displaying (minimal and maximal value are found to render one-pixel vertical lines) requires processing of all the data for the corresponding time interval. Correspondingly, time to process data depends on that. In order to provide data quickly on user’s actions the sample is read according to the chart horizontal resolution. Then whole the data is processed in background mode to build min-max chart. This dual approach allows to surf the database quickly losing no details when the surfing is stopped.Modern computers and SSD drivers provides high I/O performance. However huge files can be neither quickly read nor stored in RAM. Therefore, to read data in parallel with the recording only the choice is to store the data blocks which are either indexed by the time stamp or fixed size. Our solution is based on fixed size approach with the constant offset of each parameter storing. Size of the block is calculated as least common multiple of all the frequencies the parameters are recorded with. According to our statistic the disk usage rate is 95%. As result the time to display the sample for 2000 timestamps is less than 0.5 sec independently for the database size and the displayed duration of the test flight.

The article presents a mapping of tachyon energy in the form of quantum-energy interaction of baryon and tachyon quanta on the basis of the quantum-gravitational approach. A baryon quantum means a portion of the already known baryonic substance with the interaction transmission rates equal to or less than the speed of light, and under a tachyon quantum means a portion of a previously not observed substance – the "dark" mass with interaction rates greater than the speed of light. On the basis of such assumptions, and also with the use of the basic laws of classical mechanics and the first two principles of thermodynamics, quantum-energy models have been developed in the work that allowed all the physical parameters of micro- and nanoparticles, such as masses, densities and temperatures, interaction transmission rates etc. to be represented in a form of their energy equivalents: Екб, Епб, Ект, Епт, ΔЕб and ΔЕт. With the help of such models it has been established the following:– the tachyon quantum actually possesses all the signs of matter, that is, it has mass, density, and all other physical parameters;– regarding the energy properties, that is, the kinetic and potential energies, the tachyon quantum exceeds the baryonic quantum by about 70 ± 100 orders of magnitude, that is, it has colossal energy, which is usually called as tachyon energy.The proof of the proper use of quantum-energy models for estimating the parameters of tachyon energy carriers in this paper was done in the way of comparing the values of known physical constants (normal pressure, normal temperature, normal molar volume, Loschmidt number, Boltzmann constant, Stefan-Boltzmann constant and universal gas constant) with their numerical values, obtained experimentally by different researchers at different times.This opens up opportunities for a comprehensive study of the properties and particles of the "dark" mass and its energy capabilities.

The questions associated with improvement of efficiency of aircrafts and engines manufacture are considered. In the given context when new aircraft engines are developed, the growth of a share of easy materials such as heat resistant titanium alloys is observed. This is explained by successful complex of physical-mechanical properties, where the mechanical properties to weight ratio is the principal ones. It is noticed, that serial production’s technology of such alloys has high power inputs (double vacuum arc re-melting) and requires a strict composition control of alloying elements, impurities and uniformity of their distribution in the ingot structure. Significant difficulties are attributed to multi-stage deformation processing of large-tonnage ingots from multi-doped titanium alloys, such as ВТ8 alloy. This processing is needed in the operation chain for obtaining the small-sized rod-shaped half-products for production of GTE series blades billets. For elimination the shortcomings of serial technology, such as a large number of operations, the application of the powder metallurgy methods (PM) with technical-economical advantages is offered. The analysis of research results of composition, structure and physical-mechanical properties of an experimental alloy as ВТ8 shows that it is possible to gain the half-finished products of multi-doped titanium alloys with controlled chemical composition after sintering by methods of powder metallurgy. Mechanical properties of such alloy are approximated to serial alloy ВТ8 and thus it is permitted to use the experimental alloy as ВТ8 as constructional material for components which are not subjected to impact and cyclic loadings at the work temperatures like for serial alloy prototype. Received alloy is differed by presence of residual porosity and structure typical for two-phase sintered titanium alloys. For reducing of experimental alloy as-ВТ8 to requirements of the normative documentation (ND) for serial alloy ВТ8 and further implementation, investigation of influence of deformation processing on its structure and mechanical properties was carried out.

Hot isostatic pressing processing results in a remarkable improvement of the impact strength. Authors should be pointed out that application of additive technologies in the manufacture of aerospace parts requires extensive research&development works, and testing efforts to confirm repeatability of alloy characteristics. A mandatory procedure of the production process and material approval shall be conducted to ensure compliance with aircraft flight safety standards and regulations.

The control panel allows performing all technological operations for start/stop of two AI-450M turboshaft engines, helicopter remote control along seven channels (using seven servo-amplifiers/servomotors). It is indicated that the main means of automation of the rig is the PTC-MSB-2 program-technical complex. The basic elements and principles of operation of the hardware of PTC-MSB-2 are described. PTC-MSB-2 hardware consists of two hierarchical levels: the lower and the upper. Lower level consists of the cabs of the communication device with the object. The upper level of the PTC is two workstations (WS1 and WS2) and matrix printer. The software tools of PTC-MSB-2, their main functions and features of functioning are considered in detail. It is noted that the Running the software components is possible when the individual measuring channels fail, and when the WS2 fails. At the same time, the functions of the failed components are terminated.The goals of the modernization of the PTC-MSB-2 are listed, the principles for the implementation of algorithms for emergency protection and automation of helicopter resource testing are described. The chosen principle of automation of cyclic tests is based on the concepts of test mode, test cycle and test stage. There is a normal and emergency interruption of the test cycle. With a normal interruption, it is possible to resume the test stage from the next test cycle. The features of testing automation in regular and abnormal situations are briefly described.
IFLA Statement on Net Neutrality and Zero-rating: At the backstage of the problem
Authors: Savitskaya T. E. 
Published: February 2019

The article analyzes the IFLA Statement on Network Neutrality and Zero-rating adopted on August 15, 2016 at the meeting of the World Library and Information Congress of the 82nd IFLA Conference inColumbus,USA, its importance for the international library community, as well as the socio-economic and cultural context, which was due to its adoption. Speaking in defense of network neutrality and against the practice of the zero-rating, IFLA designated a zone of latent for that period conflict of commercial interests of Internet providers and rules of equal access of the user to all types of content without speed and additional fee. Conflict this year later, in 2017, became public in the period of active struggle against the abolition of the principle of network neutrality in theUnited States.The market rate of traffic, the green light of which was opened as a result of the cancellation of network neutrality in theUnited Stateson December 14, 2017 by the Federal Communications Commission, is particularly sensitive for libraries with limited funding, unable to pay for high-speed Internet. In addition to paid access to broadband Internet, the obvious danger for libraries is the practice of zero rating, providing free and unlimited traffic in the framework of popular social networks or package tariff plans from large corporations, which leads to the monopolization of the information market by the largest IT corporations and the further marginalization of libraries.The displacement of cultural and educational institutions as a non-profitable sector on the roadside negatively affects libraries as providers of access and as creators of Internet content; strikes both on the acquisition of funds, and on the maintenance of readers of high-quality noncommercial information. As natural opponents of progressing monetization, the Library's networks favor the interpretation of the Internet as a public service, a publicly available public resource with a transparent and stable tariff, legislatively protected from attempts by providers to receive super-profits.
