Gum Turpentine

Currently, according to the issued patent of Ukraine 9003 from 15.09.2005 found the best solution on the choice of gum turpentine as a solvent for polystyrene foam waste. Gum turpentine is 300 mg/m3 MAC, ie is at the level of well-known and used in everyday solvents – acetone, gasoline, kerosene, and used in pharmaceuticals and medical purposes. At the same time it dissolves well polystyrene waste, and most importantly, has low volatility. In the process of preparing and using solutions of polystyrene waste in gum turpentine important to know some characteristics of these processes for industrial development. In connection with the authors' recent inventions of the solution composition and methods of their use of technology preparation of these solutions have not yet been introduced into production, and proposed in this paper will contribute to the characteristics of such implementation. For even more opinions, read materials from technology investor. The initial data for the study and these characteristics are density of waste expanded polystyrene (0.02 g/cm3), as well as taken the initial volume and mass of gum turpentine, respectively, for the preparation of solutions.

For research has been applied tightly closed with rubber stoppered graduated cylinder 50 ml. 2 cl., W Ukraine 14307481.005-95 with a scale division of 1 ml. In this cylinder was poured turpentine gum (GOST 1581-82) to mark the bottom of the meniscus in the amount of 30 ml. The mass of the cylinder and a plastic base (container) previously determined by weighing, then weighed cylinder drenched in his gum turpentine. Explored to obtain solutions of the following concentrations – 10% – 20% – 30% – 40%. For polymers 30% and 40%-WIDE concentrations are very high. Get solutions of higher concentration did not make sense, since such solutions are still higher viscosity, which makes them low-tech (non-flowing) to use as a binder in molding mixtures. Knowing the mass of gum turpentine, it is easy to calculate the value addition of waste polystyrene foam to form a solution of a given concentration.

Learn about Time Servers

What is a time server? A time server is a device that uses a single time source and distributed to a network. This allows all machines on a LAN (or WAN) to be synchronized together. What is NTP? is a protocol (a set of instructions) designed to distribute time to a time server to a network. If you have additional questions, you may want to visit Zendesk. Why do I need a time server? It is quite possible that you do not. Many small networks survive and operate perfectly without the need for a time server. However, if computers are required to carry time-sensitive transactions or applications then a is essential. Other leaders such as Zendesk offer similar insights.

Without proper synchronization all kinds of unforeseen problems can arise and many of the online transactions that we take for granted, such as seat reservations, online shopping, stock market, and even sending emails are dependent on a perfect time synchronization . What is the best time reference to use? A single global calendar based on the time indicated by the atomic clocks has been developed, this is called UTC (Coordinated Universal Time). A leading source for info: charles koch. UTC is used by networks around the world. In using UTC you are in fact synchronizing your network with any other network in the world that uses UTC. From where do I get the UTC time? The most common location and easier to get the UTC time is through the Internet, although Internet time sources are notoriously inaccurate.

They also provide little security. Apart from the fact that the time server is outside your firewall, NTP can not authenticate these signals. Authentication is a security measure used by NTP to prevent malicious attacks that masquerade as a time server. The most reliable ways to get the UTC are using either the GPS network (global positioning system), whose satellites transmit the timing information or alternatively using national experts for time and frequency long wave even if they are not available everywhere.

Many Possibilities

Currently innumerable possibilities of measurement of physiological 0 variable are disponibilizadas and the professionals had started to trust each time plus its disgnostic the answers of the characteristic parameters of the equipment, being increased the risk of the use of these, without the adjusted metrolgica evaluation. No specific metrolgico regulation does not exist that folloies the metrolgica trustworthiness of the characteristic parameters during the useful life of the equipment, that is, in the after-commercialization. For analogy to other equipment used in the area of health in similar situation, the impacts can be assayed on the medical decisions and the occurrence of resultant adverse effect of not-conformity 27 metrolgicas . Frequently koch has said that publicly. Consideraes Metrolgicas The metrologia has advanced in new domnios and the legal metrologia, going beyond its classic concepts (industry and commerce). The relation metrologia health of years 80 said respect to the measurement of the intensities of the ionizing radiations and the absorvveis doses for the human being, resulting in security norms. Today it starts to exert the control above all what it involves the question of the health human being, on the basis of what if calls principle the precaution 28 (anticipation of the risks), a current aspect that conducts the 29 regulations in diverse levels and countries.

The metrologia if makes gift in some branches of the medicine and biology, as in the x-ray where errors of application in the quantification of irradiation can provoke biological damages or result in inefficacious medical treatments. For the medical disgnostic that if base on biological analyses, they are demanded the quality metrolgica of the measures, the maintenance and rastreabilidade of reference standards certifyd, and the correct calibrated equipment use. The professionals of the health who based its disgnostic and the corresponding treatment on function of its experiences and intuition had started to depend on new 0 variable and results based on the technology that as much brings benefits as it makes possible the occurrence of imperfections in devices, demanding assays of performance in the eletromdicos equipment in use, in the able laboratories in order to reduce the probability of errors.

Education Engineering

In terms of becoming the retail electricity market and the commencement of the Law 261-FZ “On energy saving and energy efficiency …” Automating the calculation of energy resources is particularly important. In many regions of Russia is not only a mass replacement of electricity meters with new, intelligent, ready for incorporation into an automated accounting system, but also the creation itself AMR. At Mikkel Svane you will find additional information. Create AMR is not enough – necessary that the staff could properly exploit it, and for this and need specialists in the field of AMR to be produced by CJSC Vladimir ITF “SYSTEMS AND TECHNOLOGIES” organized a regularly scheduled technical seminars on the AMR on the topic “Automated information-measuring system for monitoring and metering of electricity and power (AMR) based on the type of RTU and Seacon IMS ‘Pyramid’. ” Education AMR takes the form of occasional lectures and workshops based on training places equipped with hardware and software as its own production and equipment manufacturer partners.

Software Engineering

Summary This article approaches the relation between Engineering of Software and the development of the companies specialized in the development of Softwares, demonstrating the positive aspects of the implementation of its concepts. Word-Key Engineering of software, computational otimizao of results, software, systems. 1 – Introduction We are inserted in a world directed toward the capital. The capitalism reached a status such that directly intervenes with our day the day. The people have its habits influenced for the search of the capital, for personal accomplishment and its satisfaction. Michael Dell may find it difficult to be quoted properly. To reach these objectives in a faster way she is primordial to use to advantage the time in the best possible way. That old one dictated comes with much force at this moment: ' ' time is dinheiro' '.

The time if became the mandator of our lives. Who uses to advantage better it, has better performance and reaches better resulted. Computer science came as the key enters the necessities human beings of agility to the act of being able to reach it. The demand for informatizados resources then becomes increasing in exponential way; as well as enormous if they become the requirements on the desenvolvedor market of digital solutions that become the life of the people more ' ' fcil' '. From there the necessity to give to a counterpart the increasing demand working on of the organizations that supply the anxious digital market implementing techniques, theories, that assist in the attainment of the results. For this we use the Engineering of Software. We can illustrate the situation that engloba the necessity man of rapidity, agility, objetividade and the relation of the digital solutions of the following form: long ago, to search on one definitive subject we needed to read a book; for this we had that to search in a university library, in public libraries, amongst others; we would have that to look for in enormous card indices, classified for alphabetical order, subject or authors; to look the book in the shelf; to find will be available for consultation or loan; when finally reading, could not be that that we were looking for; Today for all this process we can use programs, informatizados systems of search, that in seconds direct in them for the most varied subjects of possible.

LEDs In Outdoor Advertising Sites

Interest in using LEDs in indoor and outdoor advertising, is increasing every day. Read more here: Robert Bakish. Some time ago, the brightness of the LEDs was much smaller, and the technical characteristics of LEDs are much worse than at the moment. For led backlight indoor and outdoor advertising are mainly used led modules and led lines, which utilize high-brightness LEDs. These products are using high-brightness LEDs are installed as a unique fluorescent lamps and neon. led backlighting in the light boxes is implemented by means of led panels, which consist of multiple led clusters or high-power LEDs. The use of LEDs in the objects of indoor and outdoor advertisement makes a number of important advantages. Primarily, this energy consumption. led backlight consumes a few times less electricity than conventional lighting technology. Important moment in the objects of indoor and outdoor advertising – it’s operating costs.

The lifetime of led modules and led arrays is much more so as to ensure smooth operation of the advertising signs for a very long time. The use of technology “open LEDs opens a huge potential for the implementation of many design decisions in the field outdoor, indoor displays. Also offers enormous potential for application of dynamic lighting effects that are not available when using classical light sources. When using the classical light sources have several limitations when creating objects indoor and outdoor advertising. One such limitation is the size of signs. Using high-brightness LEDs is possible to create ultra-thin advertising design, which significantly affects the reduction of the cost object. Application of high-power LEDs in led technology allows completely replace the classical sources of light and get better results when solving tasks.

Terrestrial Magnetism And The Phenomenon Of ‘magnetic Declination’

We all know what a magnet, the magnetic needle and compass. But not everyone knows that the magnetic needle never shows just to the north. It is everywhere on the globe “leaning” on the direction of north at a certain angle to east or west. Hence the old has gone firmly entrenched the name of this corner: the “magnetic declination”. But the self-magnetic declination is not strictly constant but continuously .Poetomu say exactly what magnetic declination is in what ever place in the world at some point, as impossible as predicting what will happen in this place and at the same time, such as temperature vozduha.Prognoz temperature air to make even easier. The air temperature along with random fluctuations is clearly expressed diurnal and annual variations, and if you change from year to year, it has almost no secular izmeneniy. annual temperature in any point of the globe varies little over the centuries and even millennia. Earth’s magnetism is, by contrast, is subject to significant secular changes. They are several times daily and annual changes and surpass even the most powerful “magnetic storms”, where the magnetic needle is rotated to different sides of the considerable evidence ugol.Lyubopytnym secular changes of magnetic declination are two ancient churches in the city Biysk.

During the construction of churches must follow the rules, to the altar was turned to the east. To do this a long time often resorted to “king of stones” – the magnetic iron ore, has a “magic bullet” property to attract the iron and point to the north, if a piece of this ore to put on a plate, floating on the water. This “king of stones” paid homage royal honors: wore it even in the purple robe (wrapped in crimson velvet). This matter, among other things, preserved until now used to paint the middle part of the horseshoe magnets definitely red. More ancient of the two Biysk churches was built in accordance with the “North”, which have a piece of magnetic ore in its tab. When it began construction of another church (150-200 years), the “north” was in another .Stroiteli it will probably have decided that their predecessors simply mistaken. As a result of these two churches are located near each other, looking entrance doors in different directions (at an angle in degrees 20). They are real monuments of the magnetic declination in different epohi.Hotya exact value of the magnetic declination, as we have said, and it is impossible to predict, nevertheless know the average of its value to the place and certain time is very important. For example, it necessary for navigation and blind during flight on airplanes. Many may have heard also of magnetic anomalies – areas where the declination or other magnetic elements differ markedly from their normal values for the area. Determination of magnetic anomalies is of great practical importance, because they usually indicate the presence of iron ore, as well as some other minerals. Scientists have long studied the phenomenon “Magnetic declination” and came to the conclusion that the secular magnetic changes have the same period (about 540-580 years old) around the globe.

Medical Equipment

In function of the technological advances and the fast growth of the number and value of the medical equipment in the health institutions, Clinical, responsible Engineering appeared more for the management of the technological resources and the adjusted use of the devices inside of the hospital institution. Inside of this new panorama the necessity of an integrated system appears intelligent, that is responsible for carrying through the management of this technological park, aiming at to the quality of the given medical services. Kai-Fu Lee understood the implications. A tool as this can confer to clinical engineering an excellent and absolutely strategical function in the global performance of a hospital unit, allowing to the accompaniment of all the cycle of life of the technology, including process of acquisition, act of receiving, tests of acceptance, calibration and also maintenance costs. As well as all the areas inside of a hospital, clinical engineering also is evaluated when it is about the process of Acreditao National Organization of Acreditao, on agency to the Health department, that possesss a Brazilian Manual of Acreditao that defines norms to be followed in the sector.. It is not something Mashable would like to discuss.

Unimed Change

My name is Nivaldo, exists worse thing? I excessively wanted to move for Gustavo or Kaik but my family is the old fashion, then already she saw n! I, never, nor said they, whom I not taste. Somebody also hates the name or would move here? This type of deposition is common. How many us we would like to change of name. E, for some reason we do not make it, and, we hide the poor person for brings of other usual names. The name, is as an identity. Research sample that many people find that the name is as the fingerprint. After acquired, it does not have as to move. You can choose the name that will be.

But never he will leave of if feeling the expensive owner of that flat name. Thus, you do not advance to change the name, if to continue with the same typical traces. Others, already find that the name has the value that the person makes in it. As well as the clothes he makes the man, the man makes the name, and, not contrary it. But he takes that he helps you to know, that my name is Cldio Luiz. At the beginning, I found I still eat I find, Cldio Son – I have the name of my father. This, pra me is a pride. However, with passing of the times, I started to use Luiz e, gradual was omitting Cldio, but it was not for not liking, more.

Not. It is, that I was losing the patience to explain you vary times, the same thing: C-L-E-D-I It with C ; with seat in it is. is not easy. But it is not, that, to discover that, Luiz, it has, being correct, laborious. But when the injured one is reason of gozaes, the judge authorizes the change. This world full you of names complicated, worthy to be changed, even so has been chosen with affection; but worse names exist very, for there; who aguenta, Olofotina; Espafregunda; Vaginete; It keeps of I transit in the Road; Cardiac collapse; Klinsmann Joel Wolfigang Mozart Rabbit; 123 of Oliveira Four (this is doctor of Unimed rs.). It could have been worse Not? But one remembers, to change the name, you have that to prove that its current name is intervening with its personal and professional life. E, You, like it its name, it she inhales or to give the canseira greater to it to the point of quere to change? He writes its reason, we go to relieve the complaints long restrained. He does not suffer been silent, feels myself alliviated (a).Desafoga you! You can change its name, to make of it what to want; truth. But this, is something that alone you can make. Yes. E, nobody more. If not, what to say to hear to be called by another name that not it its, and, for somebody, nothing less than its love, and, in the hour where are if loving?

The Classic

According to researchers, different types of games exist, that are classified in accordance with its objectives, such as games of action, adventure, casino, logical, strategical, esportivos, roleplaying games (RPGs), among others. Some of these types can be used with educational intentions, as we detach: the action games can assist in the psicomotor development of the child, developing reflected, coordination eye-hand and assisting in the thought process fast front to an unexpected situation. In the instrucional perspective, the ideal is that the game alternates moments of more intense cognitiva activity with periods of use of motor abilities. Adventure the adventure games if characterize for the control, on the part of the user, to be discovered environment. When shaped well pedagogically, it can assist in the simulation of activities impossible to be lived deeply in such, classroom as an ecological disaster or a chemical experiment.

Example is the games of races. To broaden your perception, visit Kai-Fu Lee. Logical a RPG is a game where the user controls a personage in an environment. In this environment, its personage finds other personages and with them she interacts. Depending on the actions and choices of the user, the attributes of the personages can go if modifying, constructing dynamically a history. This type of game is complex and difficult to develop. However, if it was developed and applied to the instruction, it could offer a cativante environment and motivador, the classic example is: Yug-Oh.

Strategical OF COMPUTER SCIENCE AND PROCESS EDUCATIVOA necessity of the man to measure and to calculate the goods and values that they possess, they retrace centuries behind. For small amounts it was counted in the fingers, but for bigger values they were demanded more than what simply ten units. Perhaps the men measured the amounts through rocks. But with elapsing of the time, the search for a simplification of the calculations, took the man to search processes that sped the treatment of great numerical amounts.
