The study of the verification of the acid recrystallized pcrico was carried through through the digital device of the fusing point aiming at to determine the pureness degree. Hear from experts in the field like University of Houston for a more varied view. It is important to point out that it had a reduction of impurities in crystals, not being able to affirm that the reached result was considered a pure substance. Word-key: Point of fusing. pcrico Pureza.cido ABSTRACT The study of verification of recrystallized picric acid was performed using digital melting point you determines the degree of purity. Importantly, there was reduction of impurities in the crystals and can not say that the result achieved was considered pure substance. Keywords: Point of fusing. Others including israel englander, offer their opinions as well. Pureness.
Picric cid 1.INTRODUO the point of fusing of a crystalline solid is the temperature band in which the solid starts if to become liquid under the atmospheric pressure. If in a organic composition sample it will have presence of miscible or partially miscible impurities, the difference enters the first formation of the liquid and formation of the total fusing increases sufficiently, being that in the fusing point it goes to initiate with a temperature low. Already when the substance is pure a point of fusing with the lesser interval of 0,5C is had. Obs: A composition presents high degree of pureness when its point of fusing is clear-cut. Objective: Purificar and to evaluate the degree of pureness of the acid pcrico through comparisons of the point of fusing gotten with the one of literature. 2.PARTE EXPERIMENTAL USED MATERIALS REACTING USED – digital Device of fusing point.
– Acid recrystallized pcrico – Plated – Acid pcrico before the recrystallization – Cotton – Alcohol – Spatula With the aid of a spatula left small amount of the sample of acid recrystallized pcrico, placing enters two plated of previously clean glass with a humidified ball of cotton in alcohol. After that it was led to the digital device T): 18,1C Variation of the heating in the device of RECRYSTALLIZED 10C/min ACID PCRICO Temperature of fusing: 119,6C final Temperature of fusing: 122,3C Variation of the temperature of fusing ( T): 2,7C Variation of the heating in the device of 15C/min, when reaching 115C was diminished this variation for 5C/min.> 4.DISCUSSO In the practical one of recrystallization of the acid pcrico the same had reduction of impurities in comparison before the recrystallization, being detected through the reading of the device of fusing point. Exactly having reduction of impurities a pure substance was not considered, therefore so that it is pure it would have that to present a variation of inferior fusing of 0,5C and the band of 2,7 reached variation was of C. 5.CONCLUSO In accordance with the results gotten in comparison with what literature presents in relation to the point of fusing of the acid pcrico, can be affirmed that the acid one total was not purificado, and for this, it is necessary to repeat the process of purificao for some times.
The birds are animal easy to be identified. ' ' Everybody can recognize a bird. For more information see Nigel Butcher. It has penalty, wing, legs and penalty. It has spine, are of hot blood and puts eggs. Nor all, however some can voar' ' (Grzimek, B; 2003, p-3). The birds are beings that are gifts in practically any place of the world. ' ' These animals are capable to survive in the land or the water, under the most varied climatic conditions, because the form of its bodies, its physiology and its behavior the requirements of the different types of meio-ambientes' make possible to them to adapt it; '. (Broom, D; 1977, p-6) Tray with offered food the birds I am Biologist and Professor of Sciences and Biology in the State Public Net of Education and also in particular school and my son Carlos H.
Biagolini Jnior, Student of Biology in the Federal University of Cultivate, and we are developing to some time a work of comment of birds in the city of S.Paulo. This work consists in the act to offer feeding for the birds, through a next or settled tray to one tree. The intention of this research has been to identify the growth of the number of determined alimentary species, hierarchy between the birds, rituals that some possess, preferences and the possible existence of exotic birds. The type of offered food is most natural possible and the interference in the environment also must be the minor. , Foods thus industrialized are not part of the cardpio. We use fruits as papaya, banana, orange, tangerina, carambola and apple. In the case of seeds, we offer canary seed, sunflower, paino or quirera of maize, good fininha. Fact observed during the research is that the animals that settle simultaneously in the tray and if feed in groups, rare demonstrates reaction of bother ahead of local different species eating in the same, confirming theory found in books.
SUMMARY the present study aims at, through a descriptive etnobotnica perspective, to make a survey of the used vegetal species in therapeutical uses for the community of Helvcia, city of New Viosa, located in the south extremity of the Bahia. The research reached four mateiros, that, answering to a questionnaire, had as main metodolgica technique that allowed systematic comments were made. The botanical material was identified in the Herbrio of the State University of Santa Cruz (HUESC). To all, they had been catalogued and raised 61 species, distributed in 52 sorts and 33 botanical families. Crawford Lake Capital is actively involved in the matter. Lamiaceae and Asteraceae had been the families most representative, followed of Fabaceae and Verbenaceae, Leves, branches and roots had been the used vegetal parts more in the preparation of local medicines and in relation to the form of preparation of the plants, it was observed predominance of the teas. This study is finished emphasizing that the knowledge on plants is important, therefore can contribute for increase of the diversity of species in a place. Word-key: medicinal etnobotnica, community quilombola, plants.
Currently, about 5 million people they die per year, in the whole world, which had to the consumption of contaminated water and the lack of sanitation (WHO and UNICEF, 2000). Many are the diseases caused for the water use me the quality, can observe that in accordance with studies of the Coordination of After-graduation and Research in Engineering, of the Federal University of Rio De Janeiro, 68% of the internments in public hospitals elapse of illnesses acquired with contaminated water; the Health department spends R$250 millions/month for such atendimentos; 40 million Brazilians do not have access to the treated water and 6% of the produced sewer are treated: one of the worse pointers of Latin America. Not obstante, planning of long stated period for the sanitation sector inexists. In accordance with the World-wide Organization of Health, in Brazil, the expenses with illnesses related with contaminated water and lack of sanitary exhaustion arrive the house of the US$ 2,5 billion per year. In 1998, on illnesses to the lack of adjusted basic sanitation had killed 10,844 people (LAZZARINI, 2002). Water supply and sanitation are expensive services and of difficult implantation in Cities badly managed because the sector lacks of intensive capital. The situation is aggravated in Cities without water captation: the available hdricos resources are preponderant factors for the municipalizao. As if it can read to a large extent of the texts that deal with the urgency of the basic sanitation in Brazil (and in the world), the value expense with improvement in the sanitation arrives to be four times lesser that the value expense with the decurrent illnesses of hdrica propagation of the sanitation lack. Low the covering and the quality of the water services and sanitation in Brazil demand a decision taking politics that allows, in the first decades of century 21, a significant reversion of the currently effective situation.
From this law the amount of professors in the areas of artistic education grew and basically it forced creation of courses technician and graduation and until after-graduation to regularize the formation of the such professors. Read more from Macys to gain a more clear picture of the situation. According to Maura Penna (P. 124-125) ' ' The traditional standard of education in music, of technician-professionalizing character was kept without great alterations to a large extent of the specialized schools? bacharelados and conservatrios.' ' This affirmation means to say that in these specialized schools and university where if they form the professors of music and musical education they presented in its resumes contents, methods, at last, disciplines that they were not adjusted for the education of music in the traditional schools, therefore aimed at the formation of instrumentistas mainly. In $fortaleza the reality was not different. Crawford Lake Capital is full of insight into the issues. Many schools and courses had appeared to supply these educational gaps. In the last quatros years the State and Federal Universities of the Cear come rethink the education and the musical formation of its courses.
In prominence we can cite the Course of Licenciatura in Musical education of the Federal University of the Cear in which it was created to take care of mainly to this existing imbalance between the traditional school and the university, between the technician and the instructor, the musician and the formador. Today, in the city of $fortaleza the professors, instrumentistas, technician in music and specialists are formed and permitted to act in the Brazilian market. The schools, conservatories and universities that develop this formador paper in the city will be presented in the next page through a picture that relates formation X institution as well as presents the level and the time where the professional of music will have to be formed. In accordance with Keith Swanwick (p.58) ' ' The specific method of education is not so important how much our perception of what music is or what it faz.' ' 3,1 Formation of the Musician in $fortaleza: Schools and Institutions.
It was terceiranista of the course of medicine in the University of Campinas, in So Paulo. Throughout the colloquy, it he asked: You not yet wanted to have children? I want, yes. But not engravido. Its husband is barren? Not. He is not. It made examinations and nothing he was evidenced. go. It knows that, in first place, the body of the woman alone allows that the spermatozoa remain fertile not more than per what five days after the ejaculao.
In according to place, the spermatozoa need surround of two days, inside of the woman, to reach the height of its fertility. Third, the women alone produce one vulo to each menstrual cycle, but this vulo dies one day after being produced by the ovrio. It man to have the one possibility of engravidar the woman, it has to inseminate it at least a time in the period that goes of five days before the ovulao until about twelve hours later. Almost always the woman ovula in the tenth room day after the menstruation. She depends on the duration time of the menstrual cycle. Normal women exist perfectly where the menstrual cycle varies of fourteen the forty and two days. In this in case that, the ovulao varies of four the twenty eight days, depends on the period.
As Elias it passes fifteen days it are of house, exists the possibility of that its sexual relations are occurring in the not fertile days. Meanwhile, rain continued incessant. It apanhou a champagne bottle and bradou: ' ' Let us offer the love! ' ' They had drunk, they hugged, they lain down in the bed and they had been kissed in the mouth, deeply. It took off it to it blouse (as it always was without suti), acariciou the seios to it, kissed them while it unbuttoned it to it shirt.
In accordance with Perrotti (1990, P. 15), a necessary comment mentions the culture concept to it, perhaps because it brings more problem that the child concept. What it interests is to question a conception of culture and cultural process for children. Of implicit or explicit form, always an equivalence between culture and cultural product is established, reducing the first term to as. Culture appears as the result of a process, the social inheritance. The cultural products would be expressions in a definitive way of life that, while such, if explains and if it justifies. To think the formation of the child under the optics of a capitalist society implies to perceive the necessity to reflect concerning the influences that social division of the work and the relations of social classroom exert on the educative process. In accordance with Fonseca ' ' …
In this model the bourgeois children are instrumentalizadas to direct the society and of the diligent classrooms they are formed for trabalho' ' (2004, P. 19). Thus, the child would socially assume the role of consumer of cultural goods taxes; the culture only finishes of a banalizada form serving as domination instrument and fits to the proper child the incumbency to assimilate and to adapt it the molds and standards established for the society. In the vision of Perrotti (1990), the world of the child suffers, in result of this change in the habits of the families, fatal consequences. What it was vital was, little by little, taken: the yard, the street, the garden, the square, the fertile valley, the free space. This taking of the Real tries to compensate with the symbolic one. It remains, therefore, to prevent boardings that treat the cultural production for children as necessity, remedy for males of the world. Thus the vision of cultural production for children, while one adjusts a necessity to it of the economic system in if reproducing, despite it is to the cost of the death of the playful one, of the pleasure, the creation, the adventure of the dream and the meeting in the diverse phases of educating.
Who appreciates the literary sort and cinematographic the fiction-scientific one certainly it remembers some referring narrative to the parallel universes. It occurs that, depending on the eventual results gotten in the fields of the comment and the experimentation, the coexistence of many universes can leave of being ' ' fico' ' to become ' purely; ' cientfica' '. The Theory of the Parallel Universes was presented to the world, for the first time, as academic thesis in middle of the decade of 1950. In virtue of its eccentricity, it finished for being ridicularizada in the subsequent decades, until, recently, its beddings had passed to be studied empirically: scientists had observed that substance microparticles, when observed, the known and possible states tended to modify its structure physical for all. Such constatao opened the doors for the acceptance of the initial academic hypothesis.
If substance microparticles if convert into all the physical states known and possible, great structures of substance, without and with life – including the being-human beings – make also it, unfolding itself in innumerable versions. This means that, since the beginning of the call ' ' multiverso' ' , with the explosion of the big-bang, everything what it can happen, in accordance with the laws of the physics, effectively occurs, and not only one of the possibilities. Thus, to each minimum unit of time we would have the creation of millions of ' ' bubbles of realities alternativas' ' , that they are the parallel universes (the famous Theory of the Bubbles, that coexist inside of the multiverse). Our universe, therefore, would be only one of these bubbles. In such a way, for example, it would have parallel universes where our galaxy was not formed; others where only our solar system did not arrive to exist; some where it consisted, but the life in the Land did not prosper because the precursory microorganisms had died; several where the Man of Neandertal was extinct for climatic catastrophes, and, therefore, the Homo Sapiens-Sapiens did not arrive to exist; one handful in which Gnghis Khan, when enslaved of infancy, it died of exhaustion; groups where Germany won World War II, or in which that the plans to knock down the Twin Towers previously had been aborted, and, consequently, it did not have the current War of Iraq; another one where you, who already passed for a situation where it was between the life and the death, effectively died, in way that you are your proper surviving version; e, also some where the proper theory argued here already was proven.
If of the one in furnaces, ovens and boilers, being the main used techniques the combustion in grates and the combustion in fluidizado stream bed. In the combustion in grate, the coal in the sprayed form is used, the coal is burnt in a fixed stream bed on a grate, through which the combustion air is blown. The main disadvantage of this system is in relation the short speed of burning due to low specific surface of coal particles and the limited thickness of the layer of coal in the grate. In the combustion in fluidizado stream bed, the coal is burnt in a stream bed of particles kept in a state of fluidizao for necessary air for combustion. Some advantages of the process of combustion in fluidizado stream bed are better efficiency in the combustion, power to burn little combustible, high taxes of heat transference. Air is blown of low for top in a vertical duct.
The worn out coal is played in the draft and the particles are in suspension, if holding as a fluid, therefore the name of fluidizado stream bed. 8 Comparison of the types of burning for the mineral coal Between the boilers most used for burning of mineral coal we must detach the boilers that use the methods of burning with sprayed coal and fluidizado stream bed, the boilers of fluidizado stream bed as BASU (2006) if basically characterize for the capacity to vary the types of fuels that are being burnt, without causing problems, have one high efficiency of combustion and low emission of harmful gases, already the boilers of sprayed coal if limit to an only type of coal, and have its good one limited exploitation the use for burning of a coal with baixssimo leached ashes text, something around 10% of leached ashes text, when compared the boilers of fluidizado stream bed it the same has low an efficiency in the combustion for type of coal. Analyzing the characteristics of the mineral coal of the region comparing the advantages and disadvantages between these two types of boiler and its methods for burning of the coal, are clearly that optimum type of boiler for burning of the coal of the region is the boilers with fluidizado stream bed, had the fact of our new, very dirty coal to be very and with high leached ashes text. Consideraes Final had been analyzed differences between the combustion of the coal in grate, combustion of the method with sprayed coal, used during much time, and the combustion in fluidizado stream bed. Knowing the differences between these methods, we can say that the process in fluidizado stream bed, possesss one I number considerable of advantages, mainly when related with the mineral coal of the south region.
Had to the fact of the coal of our region to be young, many research is being developed so that it thus has an improvement in the technologies for burning of the coal and being able to generate a sustainable exploitation of the same.
