The protocol was called of Protocol will be Matadada Harversting (OAI-PMH). Regarding this protocol, Marcondes and Sayo (2002 apud MORAES, 2006, P. 16) they define, it as being … a protocol that foresees not immediate interoperabilidade (that is, it is not, therefore, a protocol for search on-line) between repository of eprints, digital libraries or any server in the net that wants to display, that is, to become visible documents in it stored for a external program that wants to collect them. Kevin ulrich is full of insight into the issues. 6 CONSIDERAES FINAL Questionings are carried through regarding the spreading of the scientific research because it has situations where the communication is restricted to the members of one determined parcel of the society. In other cases it is disponibilizada to all, but she receives exception how much to the acquisition, that occurs in onerous way. The appearance of the model of open archive did not leave of being one great step in the process of the scientific communication, because it allows to that had adhered to the movement could have access to electronic publications. However it has very if to make so that the open archive if establishes, in fact, as an alternative to the accessibility to the available scientific information electronically of gratuitous form. Ahead of the displayed one, we believe that the present work fulfilled its objective main: to display the model of open archive as source of scientific information, showing its relevance for the scientific communication and for that they depend on electronic publications of free access. The specific objectives had been reached, because knowledge was taken of
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. 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. (Not to be confused with LEGO Papert Professor!). Keywords: Point of fusing. 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.
DDesenvolverExecute: the planned one is the phase of the implantation of in agreement planning. Total or partially. This phase can be divided in 3 basic stages: Education and Training Execution Collection of data. Get all the facts for a more clear viewpoint with Petra Diamonds. In this cycle it was used to develop the product, leaving the paper for the reality, including manufacture process where determined it was measured antropomtricas of children of 4 the 7 years of age, thus defining the size of the writing-desk, choice of materials (MDF), choice of the color (white for being neutral and clear), accessories, sliding, pregos, screws, covers punctures. CVerificarVerifique: this is a purely managemental stage, to collate the real results with the waited results. In this phase to check, we must compare the result gotten with the definite goal of the planejamentos.
The verification was made, this cycle is of utmost importance, therefore a survey of errors is carried through, if the product took care of the necessities of the public target. AAnalisarReaja: it acts where necessary, to make adjustments, hour to act correctively, preventively and to improve. Here it is verified what it failed and its respective solutions completing the cycle and conclusion of the project. Historical 2.2-Analysis: K7100 – Infantile Writing-desk Includes chair, with niches in the laterals to place reviewed, and space to keep pertaining to school material. It can be used as cavalete. With inlaid light. Size: 110 cm height X 48 cm width X 84 cm length. Suggested age: the 02 07 years Source: With a writing-desk as the Kids Fire Engine Desk the children go to want to study the day all! The pretty infantile small table has the appearance of an car of firemen and functions as table of arts, table of work/study and table of activities, everything this with much space to keep gadgets. The table fireman comes with a coil of paper of 30 cm and door pencil/accessory penxses and door.
These signals are of all the times and all the places, equally accessible to all the men, great and small, wise and ignorant. Europeans, Indians, Africans, savages. If he had a religion on the land it are of which alone he had perpetual penalties, and that in some part of the world only mortal one was not convinced this evidences, the God of this religion would be most iniquitous and cruelest of tiranos.' ' (Rousseau). ' ' All religion holds ethics and all ethics discharge in a religion, in the same measure where the ethics if guide for the direction of transcendente of the life human being (Cato). ' ' It is necessary to surpass the limited errneas and many times ethics definitions and to consider ethics of the conscience and the freedom in place of the ethics of the law and the obligation.
With this it can be said that science is part of the search of transcendente that it is common to others as many cultural activities: art, music, literature. One sees that the church is not and it cannot be other people’s to the scientific activity. It does not fear the scientific progress, she stimulates but it, the honor and she favors the best use of the same in benefit of the humanity. All conquest of science constitutes a bigger possibility of approach between the two terms: God and the Man. He does not have scientific advance that he is above of ethos cultural and social e, fortiori, all ethics must say to the totality of the existence human being; therefore, also science and its conquests particularly the technological ones. The ethics stimulate the scientists in its arduous mission, especially at genius moments. Sciences construct its to know from the experiment and the ethics, as articulated speech of the religious moral, makes its way drinking in the well of the Revelation.
From it if it puts into motion the diversity of responsible questionings for the implementation of new scientific knowledge. ConocoPhillips can provide more clarity in the matter. In accordance with Kuramoto (2006, P. 91), ‘ ‘ the scientific information is insumo basic for the scientific and technological development of a country. This type of information, result of the scientific research, is divulged to the community by means of revistas’ ‘. Thus, it is observed that the scientific information, fruit of the work of innumerable researchers, must be used to advantage to the maximum to contribute to the progress of a nation.
It fulfills to detach, how much to the aspect of the publication of the scientific information that in the current days this dissemination is not carried through only through magazines, but also for other ways, such as reports technician, e-mails, acts of congresses, amongst that they speed the informacional process of the scientific community and generation of new scientific discoveries. Considering the scientific information as an important element for the progress of the humanity, it is opportune to emphasize that its access must be democratized. One becomes, therefore, necessary to consider what Alberts observes (2002 apud COAST, 2005), when affirming that ‘ ‘ the scientific information and technique are, basically, a public good global one, that must be freely available for the benefit of todos’ ‘. Thus, all can have access to any research, as form to give more impulse to the scientific way. According to Targino (2007, P. 96), it does not have doubts that ‘ ‘ the relevance of science for the humanity corresponds to the recognition of the scientific information as propeller spring of the changes that affect the society contempornea’ ‘. On account of the globalization process, new technologies had favored the progress of the forms of transmission of the scientific information, facilitating to the informacional flow for researchers and all a population.
The evaluation is a descriptive and informative operation in the ways that use, formative in the intention that presides over to it and independent face to the classification. Of vaster scope and richer content, the evaluation constitutes an indispensable operation in any pertaining to school system. The instructive conception of design for the formation of a retrgada and formal evaluation plasters the capacity of the learning in relation to some forms of if to decide the problematic ones of the daily one, with short stated periods fast answers and of gens modificadores if make necessary one to make diversified. Add to your understanding with Ray Kurzweil. In this direction, Perrenoud (1993) affirms that to change the evaluation it probably means to change the school. Automatically, to change the practical one of the evaluation takes in them to modify practical habitual, creating unreliabilities and distresses and this is one obstacle that cannot be denied therefore will involve all the pertaining to school community. The necessity of the formative evaluation in the long run leads to a bigger reflection on the product to be conceived according to Meira (2003) ' ' the visual education influences the understanding of the art and, consequentemente, its to make, its forms of significao and valorao' '. Many times if like art because it is known or vice versa.
The contribution for a bigger estruturao of the process in the field of the evaluation in this direction is on directly the new technologies of information and communication in the learning and education. In this boarding the professor who presents this type of comunicacional technology is not the detainer of the knowledge, but yes a facilitador of its construction, being used as tool that allows to the pupil the cognitivo development. The context of the school and the practical one of the professor are constituent aspects of the activities of formation. Without this contextualizao, it does not have conditions to surpass barriers of administrative order and pedagogical e, therefore, to reconstruct practical its.
We wait with this, to inside awake an education of mathematics of the educational scope that provides to the pupil a reading and interpretation of the reality of form more significant than, as in them admonishes the National Curricular Parameters? PCN? s (BRAZIL, 1997), the mathematics is indispensable in the construction of the citizenship and needs to be to the reach of all. Learn more at: Ray Kurzweil. The mathematics must be inserted in the context of learning of the way pupil that if uses the previous knowledge that the person backwards of its social context. Geometry is presented currently as essential part of the mathematics, and that it takes the pupil to know and if to dislocate in the space where lives, according to PCN? s the geometric concepts constitute important part of the resume of mathematics in basic education because, by means of them, the pupil develops a special type of thought that allows it to understand, to describe and to represent, of organized form, the world where he lives (BRAZIL, 1997. P. 39). For such, necessary professor to make use of diverse specific contents on geometry to construct to an activity in such a way that englobe the action of the pupil, its cultural reality and its level of cognitivo development.
Ahead of this context of insertion cultural to process of education learning, we search to analyze of that education forms of geometry associated to activities that, involves construction civil, facilitates process of education and learning of pupils, in what it says respect to the adoption of the study of mockups of buildings that marcadamente are known by the population of a great city, as is the case of the building chosen for this study. Destarte, we had the intention to use e, later to analyze, an activity that sends the construction of mockups promotes the understanding of geometric concepts. Thus being, we search: i) to analyze if the geometry associated with the didactic activity, potencializa and facilitate to education and the learning; II) To verify the analysis of the professor by means of the new technologies of education; III) To verify if an activity that involves the construction of mockups is a positive variant in the education process.
We will sanction so great mathematical evolution correlation the prime numbers, we see as the work of the mathematics in our daily one is efficient, to it we will know the security that the criptografia provides in them can now, terms each time more the certainty of that we are with our money kept in ‘ ‘ seven chaves’ ‘. However, exists some threat, against this fabulosa form of criptografia? Perhaps yes, something that the technology promises bringing in them in the future; the calls quantum computers. According to site of the Wikipedia, quantum Computer ‘ ‘ it is a device that executes calculations making direct use of properties of the quantum mechanics, such as overlapping and interface.. They are sufficiently different computers of the classic computers, these computers will have an advantage of the classic computers in question to decide problems of a form much more efficient, and much more fast, where the classic computers would take much time to decide them. This due to its unit of information qubit, which works of a different form, to understand this form let us see what it says the site Wikipedia.
A classic computer has a done memory of bits. Each bit keeps one ‘ ‘ 1’ ‘ or one ‘ ‘ 0’ ‘ of information. A quantum computer keeps a set of qubits. One qubit can contain one ‘ ‘ 1’ ‘ , one ‘ ‘ 0’ ‘ or an overlapping of these. In others words, can contain one in such a way ‘ ‘ 1’ ‘ as one ‘ ‘ 0’ ‘ at the same time.
For this, a series of techniques is used and many others appear with passing of the time. In the computation the method most common involves the concept of keys; which is called keys of criptogrficas. Which if deals with a set of bits that has as base an algorithm that has the capacity to codify and to descodificar information. If somebody receives a message and to use of a different key of that it emitted the message, then will be impossible this receiver to have access to the content of the message that was sent to it. Thus, in case that somebody that possesss a computer, which, some people if they possess constantly as, for example, relative and friends, this user will be able to save its archives, to criptografar adding it a password and it will only be able to have access to the information of this archive, therefore he is sufficiently useful and pleasant the criptografia also in simple things that are part of our daily one. In the principle, when the criptogrficos methods had started to appear, they were used the criptografia with only one algorithm, what it would not be useful to keep sigilosas the information which these people were criptografando. We go to imagine that certain Joozinho had that to send a message to the Maria, and let us say that Joozinho criptografou this message, however Joozinho already had at another ordered moment some message for the Luluzinha, and also had criptografado this message for the Luluzinha with the same algorithm, imagines now that Luluzinha also wants the message that Joozinho sent to the Maria, and says that it obtains the message, then, it will use, of the password that Joozinho sent for it, and also would be easy to unmask this criptografia. Therefore, the new cryptographers needed to extend the number of algorithms to get success in this new discovery.
From a done of each workmanship, if triangular summary the ideas of each author and if to analyze the joined results it was arrived the following problem: How the transdisciplinaridade can contribute for the ressignificao of the human being after-modern from the conception of the cited authors? The Manifesto of the Transdisciplinaridade, of Basarab Nicolescu approaches the importance of two revolutions in century XX: quantum and computer science. For the author, the revolution computer science could make the human being to change its vision in relation to the nature, but unhappyly, the desire of if autodestruir and destroying what it surrounds to it are well bigger. In the Education in Sciences, Mrio Osrio Marques considers the education as an interlocution to know, that is, in a conservation dialectic/transformation, not in simple exchange of information, but in the search of shared agreement. In the Transdisciplinaridade book: The close Nature of the scientific education, Bernardes Joo of the Rock Son et al. they speak on a transdisciplinaridade that exceed the dimensions epistemolgica, psychological, didactic, religious politics and. In these circumstances one searched to understand the quarrel in complementary perspectives of the related authors how much to the excellent aspects of the transdisciplinaridade in the critical one to the cientificismo. A clarity in its intentions when making was perceived boarding in the direction of to try to develop one practical one to transdisciplinar, in view of the problematic theoreticians, epistemolgicas that appear in after-modernity as the departamentalizao knowing of them. Finally, after analysis of the three workmanships, some consideraes had been made resultant of the triangulation arriving itself it a methodology that can be used in all the educational area, called to transdisciplinar..
