Plants CAM? What they are plants CAM? Plants CAM, or better, plants MAC are plants that possess the call Acid Metabolism of the Crassulceas whose acronym is MAC and has its correspondent in English CAM (Crassulacean Acid Metabolism). Therefore, more correct of what to call them plants CAM would be to say plants MAC. However, generally, these plants are called plants CAM. Plants CAM are vegetal suitable superiors barren climates e, therefore, they open its estmatos only during the night. Which would be the advantage of this? Opening estmatos only during the night, that is, at moments where the relative humidity of air is well bigger, due to lesser temperature, the plants save water at the same time that they obtain to absorb carbon dioxide (CO2). This carbon dioxide quickly is carboxilado and transformed into a called molecule of 4 carbons oxaloacetato that, later, is transformed into malato. This last one, in turn, is directed to vacolo where he remains stored. To the dawn, these plants close its estmatos thus preventing great losses of water that occur very in dry climates, but, the same, this closing provoke the stoppage of the acquisition of atmospheric Co2.

In this direction, all the malato that was produced during the night, passes, during the day, to be decarboxylated, liberating, in the gas form, all the Co2 acquired during the night and that, in this manner, it passes to be transformed into organic composites (triose fosfato) in the cycle of Calvin as makes a plant C3 or C4. After this, these trioses will be used for the production of sugars (sacarose and starch). It perceives that plants CAM secularly separate the phase of acquisition of Co2 of the atmosphere (night), of the phase of transformation for organic composites (day). Already the C4 plants separate, space, these phases, therefore the first one occurs in the cells of mesofilo and second in the cells of the vascular beam of the case. Plants CAM, for opening its estmatos only during the night, in contrast of the C3 and C4 that open the same ones during the day, save very more water.

As already mentioned, this is an adaptation of the plants the barren environments. Plants as the cactis are typical examples of plants CAM. Many bromlias also possess this type of fotossinttico metabolism.

Rui Barbosa was the main editor of the Great Letter. According to Nassif (2005), it is important to notice that, beyond bigger jurist of its time, Rui Barbosa it had economic knowledge surprising, as if it can confer in the document ' ' Organization of the Republicanas&#039 Finances; ' , presented in November of 1890 in the National Congress. Not but it dominated the main theories economic as it had a minute knowledge of the main institucional aspects of the economy and the North American federalism. The justifications had taken that it to stimulate the monetary expansion had theoretical bedding. It supported who if could not mere evaluate the monetary politics by means of the sum of money in circulation, since he has left of it was empoado. He had the necessity, then, to inject in the economy currency that circulated. At the time, the monetary emissions obeyed the standard-gold; if it only could emit having the corresponding gold ballast. Rui faced this ortodoxia and authorizeed the emission lastreada in public headings, with the objective to finance the production and to help to esterilizar the public debt. This theoretical position brought innumerable admirers to it, between which Stolen Celso, for who the speculation of the economic depression was an event to the part, without relation with the economic policy of Rui Barbosa. Beyond acts of Deodoro ministry, and of periodicals of the time, two recent workmanships are excellent to reevaluate the paper of Rui Barbosa in the period: ' ' The Economic depression, Anatomy of a Brasileira&#039 Bubble; ' , of Ney Oak (former-president of the Stock exchange of Rio De Janeiro), that esmia the used financial tools in the economic depression, and ' ' The Financial Crisis of the Abolio' ' , of the brasilianista John Schultz, who advanced in direction to the identity of the foreign capitals in the country, greater has left of which: ' ' Brazilian capital clandestino' '.

The architecture cause perplexity also for the inconsistency of its capacity to generate the happiness becomes that it attractive for us. The houses can inviting in them to use to advantage them with a mood that we do not obtain to evoke. The architecture noblest can to the times make little for us of what a nap to the afternoon or an aspirina (OF BOTTON, 2006:17). The author suggests despite the architecture cause perplexity for the unconsciousness of its capacity to generate the happiness becomes that it attractive for we, beyond transmitting messages moral, instead of dictating laws. Of this form, the architecture invites in them, and it does not command, to follow its example. One in the ways that determined construction it possesss of being convidativa and instigante is in the mixture of elements that assist in the dither of its aesthetic one. In accordance with Szabo (1995), one of the main elements of the project architectural pointed for architects and theoreticians of the architecture it consists of the use of the light.

The author affirms that the paper of the light in the architecture possesss distinctive character and exceeds the higienicista, quantitative question mere, contributing with its intrinsic characteristics and quality in the creation of the space. The author still cites celebrates it phrase of Le Corbusier, who defines the architecture as ' ' wise, correct and magnificent game of the volumes congregated under luz' '. The narrow relation enters the light with the space justifies the importance of the illumination in the history of the architecture. Such relevance is observed in all the rupture moments that the architecture promoted, being the present light always in these marcantes periods. Second Stolen (2005) the light, of subtle form, it appears indirectly as an ethical and aesthetic position in the movements architectural. Trapano and Bastos (2006) affirm in a similar way that the perception of the forms of the architecture is disclosed by the light, that the architecture are capable to sculpture the light.

This structure, formed for diverse nets of communication, demands Mathematical Modeling, Specification, Regulation and many other pursuings of the Area of Electric-Electronics Engineering and the Engineering of Telecommunications. The Analysis of Fourier became it indispensable tool in the treatment of many obscure points of the Modern Physics, of the Theory of the Communication, Linear Systems, and many other branches of Science. Thus being, the central objective of the present work is to the same study some applications of the Transformed one of Fourier into the Principles of Communication, being distinguished in the main body of the Analysis of Signals, some Ideal Forms of Modulation, Transmission without Distortion and Filters. INTRODUCTION As already was observed and salient in the Summary, the Analysis of Fourier became it mainly indispensable tool in almost all the branches of Accurate Sciences and in the diverse areas of Engineering. Our concern in the choice of the subject was to congregate some subjects well current and to use the Transformed one of Fourier as basic tool to attack them. Also, we summarize the importance of famous ‘ ‘ funo’ ‘ delta of Dirac in the Appendix. We detach in a global vision the Random theory on Linear Systems and Processes.

On the other hand, considering that the Theory on Principles of Communication is one it disciplines basic and essential in the formation of the current engineer, we look for to contribute and to help to supply a necessity of the market of books in Portuguese Language, clear form and with all the pertinent demonstrations, having conscience that the subject is vastssimo. Remembering, despite, with the fast result of the technological progress, the diverse areas of lesser Engineering are converging and are each time the differences between them; the collection of data, transport, storage and processing of information made with that Disciplina Principles of Communication if became a necessity in the Courses of Engineering. The market of work in Telecommunications has promoted seminaries and courses for the good formation of hand of specialized workmanship and research directed toward this area. We must emphasize, still, that some Courses Technician have an introduction to this discipline. In this in case that, it competes to the professor making of this Monograph a plastic and alive organism; it competes to it choosing, as the direction of the Course, what it can make and what can leave according to make, what can put in front or postpone, peculiar conditions of its pupils.
