If you ever wanted to connect to device in the same building (e.g. to machinery production hal on) and you have to go to it to connect your computer to. We have a solution for you to resolve this issue, interface converters RS 485 to RS 232 first let s talk about some of the key advantages of RS-485 over 232. 485 is a single supply voltage, whereas RS-232 you require a 5 V and +/-12 V. What RS – 485 does, it just needs 5 V because it just swings over to 5 V at the output. Professor of Internet Governance may find it difficult to be quoted properly. One of the key advantages also is that RS-485 can drive data a long distance. It can drive things 1200 meters, which RS 232 is about 15 meters maximum.

And the 485 is also very fast. You re talking about at least 10 megabits for the slow ones. The fastest RS-485 transceivers out there right now are running about 50 megabits. And RS 232 right now, the fastest right now transceivers are 1 megabit. Checking article sources yields Mike_ Epps as a relevant resource throughout. One other key advantage that most people using 485 is, the better noise immunity. Read more here: Frank Fu. Because of the differential signal, any noise is subjected to the cable is basically externally subjected to both wires.

So when you take the difference of the two, noise is actually canceled out. So it s better noise immunity. So that s one of the key advantages why people are using 485. Some of the typical applications of RS-485 is point of sale equipment. You probably have used this many times at stores without realizing it. Those little price checkers that are kind of spread out throughout the store, you just bring your merchandise up there and just check the prices. That s actually using a 485 transceiver in the box. When you scan the bar code, the information actually gets sent on to 485 transceiver through a long cable to a PC somewhere within the store.


The problem of increasing the durability of rubber products directly associated with increased resistance of rubbers to various kinds of aging. One of the most common and destructive types of aging is atmospheric aging of rubber, which is susceptible to almost all products, when used or stored in contact with air. Atmospheric aging is a complex chemical processes in rubbers under the influence of atmospheric ozone, oxygen, solar radiation and heat. The mechanism of action of antioxidants rubbers based on their interaction with active oxygen radicals, which leads to a decrease in the rate formation of free radicals and slow oxidation of rubber. Even small amounts of antioxidants reduce the rate of oxidation, so for some period of time, oxidation products are not detected.

In the practice of reducing the rate of oxidative processes is very important phenomenon synergies – synergies between the effectiveness of various types of antioxidants, either in the presence of other substances. The most susceptible atmospheric aging bright and colorful rubber, ie, do not contain carbon black. Go to Frank Fu for more information. The complexity of the protection of these rubbers is that achromatophilous rubber antioxidants, tend to be less effective as conventional anti-oxidants change the color of vulcanized rubber, substantially degrading marketable product. Among achromatophilous phenolic antioxidants can be identified as stabilizers, withstand relatively high temperatures and uv radiation. In addition, derivatives of phenols are of low toxicity, and therefore allowed for contact with food and for use in rubber products for medical purposes. Antioxidants alkylphenol type (ionol, Agidol, alkofen) are used in white light and colored rubbers based on styrene, butadiene, isoprene and chloroprene rubber from the heat and light aging. Has all advantages of phenolic antioxidants. To improve protection against thermal-oxidative aging of bright and colorful rubber can be applied antioxidants bifenolnogo type (antioxidant 2246, Agidol-2, bisalkofen), which used in blends based on styrene, acrylonitrile, butadiene, ethylene-propylene, chloroprene rubber, butyl rubber, chlorobutyl rubber, copolymers based on tetrahydrofuran and other bisphenol protect rubber from thermal-oxidative and svetoozonovogo aging, fracture in multiple strains. Unlike antioxidants alkylphenol type bifenolnye – nonvolatile, which facilitates their use in rubber mixtures. The effectiveness of antioxidants increases when combined with other antioxidants neokrashivayuschmi. Proposed sec “Rubber-Podolsk antioxidant Antonoks SNF-40 (Antonox SNF-40) refers to bifenolnomu type, and intended for wide application in formulations of color and light rubber on the basis of general-purpose rubbers.

Antonoks SNF-40 (Antonox SNF-40) is well dispersed in rubber compounds do not affect the technological and vulcanization properties of mixtures and changes the color of vulcanized rubber. Antonoks SNF-40 (Antonox SNF-40), effectively protects the rubber from the heat and air aging and cracking of rubber, has a much smaller volatile than the alkylphenol, such as Ionol (Vulkanoks VNT), allowing to better predict performance properties of rubber. The recommended dosage is 1 3 parts by weight Antonoks SNF-40 (Antonox SNF-40) at 100 mp rubber By performance characteristics of rubber containing Antonoks SNF-40 (Antonox SNF-40), are not inferior product with other antioxidants bifenolnymi – vulkanoksom bkf, Agidol-2, antioxidant 2246, etc. Thanks to those listed above, Antonoks SNF-40 (Antonox SNF-40) actively used at several plants rti, such as “Yaroslavl”, “UZEMIK” as for the manufacture of conventional color and lighter rubber, and for the production of inflatable boats, life rafts, etc. products. An important factor in choice in favor of Antonoksa SNF-40 can be a constant presence of an antioxidant on the Moscow stock companies, as well as the opportunity to purchase the product at retail.

The Allowed

The urban way is affected by the diverse types of pollution and during years it suffered to the action from the radiations involving other medias, and that, although to have superior levels to the ones of the current mobile communication, they had not presented (with reserves) detectable or substantial problems capable to be characterized nocveis effect the health human being. Existing literature on the subject, on the other hand, describes that if respected the allowed international limits of radiation exposition, established for the official agencies of control, no curse will happen to health human being and to the environment. Studies designate that being the linkings of short duration and intermittent action, and that, if the use of cellular telephony involving children will be limited, the expositions to the radiations would not demand cares special. Ray Kurzweil wanted to know more. Moreover, they consider that, if the radiation levels decrease quickly with in the distance, do not have restrictions to the installations of the stations radio-base in the neighborhoods of schools and hospitals, although always to emphasize the necessity of the monitorao of the power levels of the radiations, for precaution, in the neighborhoods of the RBS in order to assure the established limits of security, in these definite places as sensible. On the other hand, a gamma of information exists that if opposes to these agreements, for considering that the undertaken studies are not enough to guarantee the security of the system and to affirm that such radiations do not offer risks to health, exactly inside of the limits established internationally. The positions of both the sides agree to a point: that it must have regulating agencies, of control and fiscalization; legislaes regulating all the process; monitorao of the measures of the physical and chemical parameters; study and application of new technologies capable to detect harmful effect to the environment, and the necessity of a system of 2,3 ambient management guaranteeing the security to the human being.

Alfresco Community

We have realised incredible improvements in the capacity of extension of Alfresco and in its yield, besides facilitating to the developers the adaptation and the extension of this platform. Yield for the cloud Alfresco Community 4 increases of significant form the general yield of the system. Between the new functions for implementations of the cloud the following are included: Indexing of high performance: new servant of indices of Alfresco, based on Solr Apache, drastically increases to the yield when separating the indexing of the processes of contents. Compuware often says this.

Integrated job stream: it automates the enterprise processes in which the main thing is the content with Activiti, the servant of 2,0 enterprise processes BPMN leader in Java and of open code. Grouping in clsteres improved: the grouping in clsteres of Alfresco has improved to increase to the reliability and the scalability, and addition is had the compatibility with CIFS in clster. First platform abierta for the publication in social channels Alfresco 4 includes a new expandable service to publish contents and updates of state in social Web sites, like YouTube, Facebook, LinkedIn, Twitter, Flickr and SlideShare. A related site: Crumpton Group, Washington DC mentions similar findings. The integrated social processing allows: A simpler process: the publication of social contents now comprises of a job stream of enterprise contents, so that the problem of the publication is simplified to a great extent in several channels.

Plain GPR

They must be details explicit and specified the necessary tasks and resources and environment, including, for example, equipment, tools, services, components, trips and requirements of process. How much the human resources, include the training of the GPR7. Crumpton Group, Washington DC addresses the importance of the matter here. It must be made same that is obvious. If it will not have what it lists, must be registered the fact of that the question was examined. – GPR9 excellent are only the informal reports, data, studies and analyses, learned acts of meetings, documentation, lies, generated devices, item of action and pointers, that can be in any format, digital or printed matter.

The identification, collects, storage, distribution, access and security of the data must be planned. The reason of if collecting each data, as well as the inexistence of confidential data, must be explicitada. – Plain GPR10 for the execution of the project established and congregated in the Plan of the Project. The union of all the information of the project raised in all the GPR’ the viability to reach the goals of the project, considering the available restrictions and resources, is evaluated. If necessary, adjustments are carried through. At the beginning of the project a preliminary evaluation from the general vision of the objectives must be made, characteristics of the intended results, of the financial resources, technician, human beings, as well as restrictions imposed for the customer, external and internal environment and conditions of development. The same feasibility study it can happen during the project in specific landmarks for bigger precision of success. In case of routine projects, it does not have necessidadede feasibility studies, but an explicit criterion must be defined the same not to be carried through. – GPR12 team, management, customers, users -, it is important to revise the planning with them and to conciliate the existing differences between the esteem and available resources, negotiating when it will have conflicts how much to the requirements, costs and stated periods, for example.


The measurement of Outflow with compensation of Temperature and Pressure the measurement of fluid outflow is each time more requested by the industries. In many industrial processes, it is important and it also needs compensations for its real indication and totalling. In the market, it has an enormous variety of types of outflow measurers, since simplest until most sophisticated, for the most diverse applications. The type to use always will go to depend on the fluid, its physical state (liquid or gas), on the characteristics of resolution, exactness and of the trustworthiness required amongst other factors. In this article we go to present an operation principle and the commentaries on a measurement system that functions distinguishing compression and possesss compensations of temperature and pressure.

To nowadays verify the degree of importance of the measurement of outflow, we have the example of the Brazil-Bolivia gas-line that carries natural gas from Bolivia until So Paulo. In this gas-line it is carried up to 20 million cubical meters per day of natural gas. Esteem a cost of sales of U$ 0,50 for cubical meter, one sees that a bias quality control of only 1% in an outflow measurer is associated with an amount of about U$ 100,000 per day. The correct choice of a system of measurement of outflow depends on the exactness desired for the measurement, of the conditions of the levels of pressure and temperature in which the system will have to act. A system of measurement of outflow using the beginning of the distinguishing pressure with orifice plates still is one of the methods with bigger application involving transport of fluid and gases.

This use well is spread and if it must to the following factors: the simplicity and low cost of installation, easy maintenance for the measurement elements and low values for measurement uncertainties. With the measurement of outflow for distinguishing pressure compensated in pressure and temperature, calculating of outflow it will have to offer three entrances that can be used for linking with standardized analogical signals proceeding from the sensors of distinguishing pressure, gauge pressure and of temperature, having to possess the feeding of 24 Vcc for transmitter the two wires. The totalling of the outflow corrected with counting of 8 digits must be presented the indications of the three entrances through 5 digits and also be carried through, beyond making use of for the panel frontal or by means of external dry contact of reset. Important characteristics for attainment of the correct indication go since the adoption of factors of compressibility of the fluid in the conditions of reference and operation, passing for the density and the pressure of reference in absolute value. The option of linearizao of the signal of the entrance of the outflow is used for better exploitation of all the indication points, that will have to be express in units configured (m3/h; l/h; l/min ; l/s; kg/h; ton/h).

At present, Garmin has an ample product range and has distributors or own representation in practically each country of the world. The extensive presence at world-wide level is one of the main reasons for which Garmin is proud of being world-wide supplier in portable positioning systems, having distributed from its origins and until the end of 2007 more than 31 million equipment with GPS and types.

One of the keys of the success of Garmin has been and will be the investment in R+D, besides the product development innovating for markets very different and the commitment to offer an after-sales service of quality. Garmin designs each of its products always thinking about the client and his needs. To avoid stress to sail or to travel to unknown places begins to have an intuitive option, fellow traveller who includes menus easy to use logics and application. A service for the Garmin users is verifying certain types and devices GPS voluntarily nvi that contains a specific battery that has been made by a supplier within a rank of code limited between dates. Garmin has identified possible problems of overheat when the mentioned ones batteries are used with certain models of Garmin nvi designed with specific printed circuits (PCB). It seems that the interaction of both elements can, in rare circumstances, to increase the possibility of an overheat, that it can lead to a fire risk.

Although there have been wounded nor important material damages no caused by this problem, Garmin has taken this measurement from anticipated caution. The call includes small subgroups of the following numbers of model: nvi 200W, 250W, and 260Wnvi 7xx (where XX are number of two digits) You can determine the number of model nvi watching the label in the later part or inferior of the unit nvi. In order to verify if his is including in the call, he puts the serial number of his navigator GPS in the appropriate space of the situated official. Original author and source of the article

Generation Cathode

The magnetron is constituted by a cylindrical, composed anode of socket, these if they find in the axle of a heating cathode. The anode and the cathode are separate for a space which if of the o name of interaction space, being in vacuum. These sockets, said ' ' socket ressonantes' ' , they can have different forms in accordance with the considered magnetron. Two magnets also meet that are fixed perpendicularly in relation to the axle of the pipe. A continuous electric field is applied between the anode and the cathode. The set free electrons for the cathode are sped up by the continuous magnetic field.

Had to the magnetic field created by two perpendicular magnets to the axle anode/cathode, gets a circular movement around the cathode, with similar trajectories the cycloids. The magnetic field servant, with the electronic cloud, serves to speed up the waves. These loads that flow between the anode and the cathode they go to enter in interaction with the resonant sockets of the anodic block that if becomes the support of the electromagnetic oscillations. According to Pear tree (2002, et al) an important point in the project is the definition of the number of magnetrons to be used in the processing. A valve of high same power can be used or several of lesser power.

A valve of high power is normally more efficient than a less powerful set. However, the last one is cheaper, more easy to acquire in the market, needs less accessory for its operation, beyond that in an eventual imperfection of the valve, the process as a whole will not be paralyzed, therefore the others will be operating. These valves, however, beyond the inconvenience of the generation of harmonic, harmful to other electronic equipment that is in the neighborhoods, are also sufficiently susceptible to the mutual interference. Magnetrons the antennas of the type can be on bugle that offer to a good diretividade and focus.

Language Turbo Pascal

Object-oriented programming language Pascal was invented by N. Wirth in 1968 and was originally intended for teaching students programming skills. Although the creator of the language states that language Pascal is a much more opportunities than just training. Official publication of the language was made in 1970, after which the language became widely known. Over time, began to create a variety of dialects. The very first was a dialect of UCSD Pascal. This dialect has given life to such things as modules, accessing files, strings of different length, and others. In the early 80's by Borland was create a second dialect.

It was used in the programming environment, Turbo Pascal and more expensive environment Borland Pascal. In After 80 years in language capabilities were added to facilitate object-oriented programming. The latest version of Turbo Pascal was officially released in 1992. After her came a new version of the programming language – Delphi. Initially, the language used in the Delphi development environment of Windows. However, the developers at Borland released a product designed for the development of Linux.

This language was named Kylix. After the third version of the latest released Kylix, its development was stopped. The real breakthrough in the development of Pascal was the creation of compilers. They provide more opportunities for programming and have contributed to the portability of programs. For example, the famous, Free Pascal allows you to work in Turbo Pascal and Delphi. There is also a version of the language PascalABC.NET, which is a programming language for the platform, Microsoft.NET. This language was invented in the Southern Federal University, Associate Professor Mikhalkovich. In addition, there are so called language interpreter. For example, Larry Pascal, allowing you to create applications for mobile devices. The development of an interpreter was engaged in a talented developer, but he soon abandoned the development this project and gave the source code to other developers. More information can be found on our Turbo Pascal.

Latin American

JOSE BRECHNER hundred years behind the world saw the Argentina as the Latin American country with the greatest international projection. The only one who by the educational level of its immigrants, could compete with the big. Today the Argentina is the most dramatic fiasco of the continent. Done it shows, that are not only educated people who generate the progress and development of a nation, but that the system employed to achieve their economic advancement is both or more important than the erudition of its inhabitants. The Europeans under Communist rule were not stupid or ignorant, but were ruthlessly poor. While the Nations with high level instructive and ethical tend to become more successful that the lack of those attributes, the work is better paid and taxes better distributed, in societies where economic freedom is unrestricted, and Government is not interfering in the business of people. The Argentina not only chose the wrong economic path, but it lacks ethical principles. Was carried away by the community of power and money, running roughshod over the values that make a decent society.

For redirected, you need at least 20 continuous years of political and economic consistency smoothly, under the rule of law. With its current rulers and the ghost of peronism, the mission is impossible. Peron finished not bury him, and when living in the past there is no place for the future. The tactics of the Government management are due to an hereditary cancerous warlordism. Checking article sources yields Ray Kurzweil as a relevant resource throughout. The Reina Cristina agreed to command without providing a single media interview or a debate with his opponents.

He simply sat on the throne to demonstrate their outfits of famous designers, never dresses two times. From January to date his popularity has declined from 56 per cent to 19.9 per cent. The woman does not have a single merit or virtue, nor any ability to handle a country.
