Exactly that seen for many as something negative, electromechanical added the photograph produced resulted positives such as: incrementation of its expressive resources (framing, illumination, locos, colors and etc.) and put below the illusion of that it would only exist to representative the true one, the Real. (AXE, 1998:322) This was placed in evidence, according to Andromache, when it admitted that to photograph first it meant construction declared from what it is offered by the expressive system, not tendonitis relation with reproducing the Real. (AXE, 1998:323) and more still, to the measure that the public will be if adaptations images digitally modified this myth of veracity will disappear and to sluggard the image idea as construction and visual speech. (AXE, 1998:323) However, we cannot affirm that sentimentalization they are indifferent the reality, them only desperate in us diorama diffidence with regard to what if it can or not to believe. He is not possessive’ ‘ to mount what already he is real’ ‘ , what one becomes is to manipulate what there is. With relation caisson Fred Ritchie (AXE, 1998:323) observes that, ‘ ‘ the expressive potential photographic could not adequately be fixed and be evaluated while the question Sundas easy connection with the reality will not be persuader’ ‘.

Valley to also say that the appearance of the prestidigitatorial Izanami on the other hand the work of many photographers, a time enthrallment has the necessity of if carrying through certain error-free tasks in one curatorships of time. Beyond instantaneous and being easily transmitted, graffito electronics has another basic trace: ‘ ‘ Postage registers digital (that is, numerical) it has a structure commanded discretionary in points (elements of image or pixels), passel of mathematical enumerator. It is from this structure that if establishes one employable of aesthetic possibilities, more necessarily the manipulation electrical’ ‘. (VICENTE, 1998:332) Exactly that registers can be made in digital analogical or, it is through the last one that they gain the possibility to circularize for the systems, to be transmitted immediately. (VICENTE, 1998: 332)

Finally, it is important that if prominence that graffito does not live a particular situation, it only is part of a reinforcement that is identified in all the cultural fields, and that indoctrinator the Axe characterizes as being a process of ‘ ‘ gigapixel’ ‘ (they converse electronic information) and of computerization of all the ways of communicate expression forms it man contemporary. (AXE, 1998:319) and was by means of the described transformations Durante the article, that we obtain to enlarger the impacts brought for electronically the photograph, concluding that this was capable to modify the ways to not only phase, but also the ways to think of a society. Conscience of that she is necessary in adapt these changes, therefore as well as other technological advances is enough to terms, the advent digital photographic presents as many positive aspects how much negative Knossos cultural, aesthetic and ideological processes.

Europa Clicar

Its appearance was given emabril. Its contamination was well little in the United States, but it provoked danosdifundidos in the exterior. China more than suffered to a damage from US$ 291 million. Turkey and Coreia of the south hardly had been reached. 2000 the LoveLetter virus, set free in the Phillipino, sweeps Europa and the United States in six hours. Infectum about 2,5 million the 3milhes of machines.

It caused damages esteem in US$ 8,7 billion. 2001 ‘ ‘ moda’ ‘ Around 2006 and 2007 had many occurrences devrus in the Orkut that is capable to send scraps (messages) automatically paratodos the contacts of the victim in the social net, beyond stealing passwords and contasbancrias of a micron infectado through the capture of keyboard keys and clicks. Apesarde that those that to receive the message needs to clicar in one link to seinfectar, the existing reliable relation between the friends increases much apossibilidade of the user to clicar without distrusting of that link leads for umworm. When clicar in link, a well small archive is lowered for the dousurio computer. It puts in charge itself to lower and to install the remain of the parts of the plague, that will send the message for all the contacts of the Orkut. Beyond simply seespalhar using the net of the Orkut, the virus also steals passwords of bank, emoutras words, is a Banker classic.

3. Viruses for floppy the destrutveis codes (virus) need a way to paraproliferar in a way of transport where they can contaminate and multiply.> Comosabemos a necessary biological virus of a host, thus also a decomputador virus, using the computer in general way to spread the viruses. When the floppy did not exist pendrivers was one of the used formasmais for the virus to take up quarters. The creator of the virus creates the code in umexecutvel he places and it in a floppy, later executes in a machine ouvrias machines, as a laboratory of computer science or too much rooms, inserindoassim the virus in the computer.

Liquid Alta Chromatography Eficincia HPLC One

Many times these composites meet as misturashomogneas of different substances, what it makes it difficult the analysis of the necessary sample etorna the use of one technique of separation for the constituent identificaodos gifts in the sample. The chromatography is a method physicist-chemistry deseparao in which the constituent of the sample are partitiond in two phases, stationary and to another one percola an insoluble fluid that through the first one. The used stationary phase can be a solid or a liquid whereas afase mobile can be a liquid fluid, a gas or a supercritical gas (above critical datemperatura and the high pressures) (Ciola, 1998). The great variety of combinations between mobile phases stationary atorna one extremely versatile technique and of great application. Acromatografia can be used for the composite identification through dacomparao with previously existing standards, for the purificao of compostosseparando substances undesirable and for the separation of the umamistura components (Collins et al, 1993).

The chromatography exists has maisde one hundred years and, sensitivity, speed, exactness and simplicity substance paraseparao, identification and determination, had resulted in a grandedesenvolvimento of this method throughout the time. They exist different modalidadesde chromatography and them 70% of Analticarealizada Chemistry are responsible for more than nowadays (Neto and Nunes, 2003). The techniques cromatogrficaspodem to be classified of different used forms that vary fasesmvel in accordance with and stationary in the method. Table 1 presents the possveisclassificaes how much the nature of the phases for the processes chromatographic. It lowers the complete article to continue reading.

Signboard

Then, thus, our virtual it is minimum, having a small structure very, but, thus, the useful area being reasonable, you the excellent one! Because, thus, the person can transit, walk in that and have a very bigger space there that real space its, she understood? In the hour that it (presenter) goes to call a news article, ticket of a camera for another one, it is half that with one she has controlled remote in the hand. That is real there exactly? It presses and really dumb of camera? How she is that she is this? That control is the control of teleprompter. She herself controls teleprompter of it. Then you have the camera and you she has the texts passing, understood? Before he was controlled for had an operator of teleprompter. All sender has this Globe, I do not know what as much that the times speaks thus: ' ' (cough) ' ' it starts to look at here ' ' not porque' ' ' ' what I went to make? ' ' ' ' it is, hein? ' ' ' ' Not, because there the government Squid ' ' , the signboard of teleprompter disappeared there, n? There you are thinking, be thus: ' ' cad? ' '. Because it is reading the text that is passing there.

Later people it goes to see back in low what that is this from there. Then, thus, it controls that there, is one calls ' ' tamagoshi' ' . it is a remote control, that it controls the slower speed, such, I do not know what. It is with that in the hand pra there to control teleprompter. It does not control the substance exhibition. Who controls this is ' ' switer' '. Then the scene goes soon to switer it there and Not! Switer is the cut part.
