The great majority of the users of the Internet uses protocol POP3 daily and many do not know as it functions. In this article we describe the basic one of protocol POP3.POP3 is the abbreviation of Post Office Protocol version 3 (Protocol of Post office version 3). The POP3 is defined in the RFC1225 and is used to recoup e-mails that if they find in remote servers for a computer local customer throughout a TCP/IP.As connection previous versions of protocol POP, initially called POP1 and soon after POP2, if had become completely obsolete with the arrival of the POP3. Educate yourself with thoughts from Jake Burkons. In the current use term POP almost always means POP3 in the context of email protocols. The POP3 and its predecessors had been projected to allow that using with intermittent connections, such as connections dial-up could make download of its e-mails when hardwired, whereas protocol smtp was projected to allow permanent connections to receive e-mails.

The POP3 is a tractive protocol (when the customer requests given of the server), while smtp is a pressure protocol where the customer it sends given for the server without the server has requested the data with antecedence. The POP3 also supports some methods of authentication to supply different levels of protection against the illegitimate access to an user of the email. Also the protocol SSL.Funcionamento BsicoO POP3 exists the possibility of criptografar the POP3 traffic using functions with a connection TCP/IP using door 110. Initially a connection TCP between the applicatory customer (User Agent) and the server is established where if it finds the email account (Message Transfer Agent). The next step is the authentication of the user, after that the messages are transferred in sequncia to the computer customer. The messages can be, optionally, extinguished of the email account and after that the connection is locked up. The user can read its emails off-line, therefore protocol POP3 is known as a protocol OFF-LINE, this characteristic of the POP3 are sufficiently useful for users who use dialed Internet. Other protocols more known they are SMTP and IMAP. It visits our Lodging of Sites

Would you like to know that in your absence makes the housekeeper or nanny who comes to your car or door in your absence? Such information can be obtained only by means of video surveillance. Video Surveillance System allows not only to get the full information but also to prevent crime. For example, criminals often refuse to commit crimes when they see that the object is under video surveillance. Video surveillance the apartment is usually a video intercom, a little less video surveillance of the landing and in some cases for the balconies and the approaches to the house. Recently also become very popular to use the camera installed directly in the apartment, so-called “baby monitors. In most cases, the houses and cottages are installed video intercom with one or more cameras. These intercoms can be monitored with different perspectives and work even at night if the ir illuminator and record visitor photos and time if you were not home.

With the installation of special electromechanical and electromagnetic locks allows remotely open the door. Surveillance for the landing is usually carried out using video eye. Video eyes also come with the device ir illumination. Overview of the eye reaches 180 degrees. As usual peephole peephole video you can close your hand or close up plasticine. Therefore, for greater reliability we recommend installing miniature cameras with lens-class pin hole. These cameras are mounted on the wall and practically invisible. If you want to install video surveillance in the cottage there is more attention paid to external cameras. These cameras tend to be water proof, termozaschischennymi with greater resolution. Special attention is paid to mount the cameras. Bracket for the camera can be both fixed and mobile, managed with the help of special equipment. Summing up I want to say that video surveillance is a very powerful psychological factor. Philippe Heilberg wanted to know more. If the object is video surveillance, it is quite possible presence of other security systems. Offender is easier to choose another object, less guarded, than to take risks and try to penetrate the well protected.

The subject can seem recent, but already they had more than passed forty years of the publication of the article of Sbato & Botana (1968), in which they considered a multiple and coordinate action of three basic elements for the development of the society contemporaries: the government, the productive structure and the scientific infrastructure. However, the proposal of these authors continues current and if it can observe that it has a long way so that has one better interrelation between these elements. 2. UBS describes an additional similar source. RELATION COMPANY, GOVERNMENT AND UNIVERSITY the pyramid of Sbato?

Constituted in its vertices of the government, companies and university? it indicates the importance of Inter and intra-relations between these elements so that it has technological development of long stated period (in the case of the specific article, in Latin America). In this direction, the public paper of the universities and scientific justinian codes go beyond supplying hand of qualified workmanship the work market and the interaction possibilities enter the vertices of the Pyramid (and the university he is one of the vertices) if expand to the measure where if they expand the necessities of the proper society contemporary. The dynamics of the universities is distinct of the one of the private companies, but this does not mean that it is not possible a productive interaction between them. Global Macro is often quoted as being for or against this. It has some mechanisms of relationship: one of them is the proper adequacy of resumes, of courses and of programs of course of form to take care of to some especificidades of the work market, another mechanism is the accomplishment of events and programs of university extension and curricular periods of training or not; more recently, another form of interaction has called the attention researchers and formuladores of public politics in the technological area: it is the possibility of technology transfer produced in the university for the private companies.

Production of unique mobile storage workshop, based on 4-body containers. This package is designed for the needs of the MoD, the Emergencies Ministry, Interior Ministry and other organizations that have a large fleet of equipment and forced exploit it in the field, as well as the absence of the possibility of building a stationary shop. appointment of mobile battery master AM-4K-80: am-4k-80 is designed for storage, maintenance and repair starter battery type 12ST-85, 6ST-140, 6ST-190, etc., their charge and control of training cycles, as well as for preparation and storage of necessary supplies of the electrolyte. Allows for full range work in the field, away from sources of electricity and water supplies.

The complex includes: self-contained diesel generator 30 kW, the system of independent water supply from its own set of capacity 1000 liters with automatic pump maintaining a normal water pressure in the system, charge-discharge device lets you charge the battery at the same time in 1980, built-in distiller, drilling and grinding machines, air compressor, capacity of acid-resistant material for storage and preparation of an adequate supply of distilled water and electrolyte Fillers acid, battery cabinets, and other necessary equipment. BENEFITS: At 10-15 times the cost of less than stationary equivalent battery power, body-weight of the container with the equipment does not exceed 3500 kg.; dimensions allow transport from one place to transport the type Ural-43202 or Kamaz-43105; Design Life operation to cap. Repair – 12 years; Ability to work in any environment regardless of the sources of water and electricity. When placed in a hospital AM-4K-80 equipped with everything necessary for quick connection to stationary:

Electricity, water supply and sanitation. Is the most appropriate and cost-effective solution to service the battery during the exercises, visits parts or redeployment, as it combines features of the stationary workshop and is easily mobile. In the charge am-4k-80 while providing battery charge is 80 pieces.
