Periodic Table

Periodic system of elements (Mendeleev) – classification of chemical elements, allowing them to reveal the dependence of various properties on the atomic mass (more precisely, the number of protons in an atomic nucleus). The system is designed Russian chemist Mendeleev in the years 1869-1871 based on open them in 1869, the periodic law and is its graphic expression. Filed under: NY Museums . Total invited several hundred variants of the image of the periodic system (Analytical curves, tables, geometric figures, etc.). In the modern version of the system is assumed mixing elements in the two-dimensional table in which each column (number of columns is 8) determines the basic physico-chemical properties, and the rows represent the periods, to some extent similar to each other. The original work was titled Mendeleev as "Experience of elements based on their atomic weight and chemical similarity. According to legend, the idea of such a system came to him in a dream, but we know that once asked how he discovered the periodic system, Mendeleev said: "I'm over it, maybe twenty years of thought, and you think: sitting and suddenly Done.

German L. Meyer in 1864 on the basis of data on atomic weights suggested a table showing the ratio of atomic weights for several characteristic groups of elements. Many, especially in Germany, and believe it discoverer of the system – in 1870 he published his table of elements, developed, apparently independently of Mendeleev. Not to be confused with copyright, most students of the Western world are studying this system simply as "periodic system of elements", without mentioning the name of the discoverer. The essence of the discovery is that with increasing atomic weight of the chemical element of its properties do not change monotonically, but periodically. After a certain number of different properties of elements arranged in increasing atomic weight, the properties begin to repeat.

For example, sodium, like potassium, neon like argon, while gold is similar to silver and copper. Of course, the properties are not repeated exactly, are added to them and change. Subsequently, it became clear that the periodicity of the system elements is determined not by atomic weight, and the nuclear charge or atomic number of which depends on the structure and the filling of electronic shells of an atom of the element (atomic orbitals).

Leo Castelli (1907-1999) was until the fifty years which in United States is considered a typical European: dilettante, fond of social life than to work, womanizer and adventurer. But then opened its store in SoHo in New York City and became the Gallery: the man who gave entity and body to pop-art, the standard bearer of minimalism and conceptual art, which discovered to Jasper Johns, Lichtenstein, Pollock, Rauschenberg or Warhol. The host of the key holidays, art dealer of the artists who had a European who reigned for four decades in New York, and from there retook Europe with a satellite network of galleries. For more information see shimmie horn. Annie Cohen-Solal arrived in New York at the end of the 1980s, in time for fall fascinated by the spell of this enigmatic man, which held long talks, supplemented with testimony of relatives, wives and ex, children, artists, collaborators, friends and adversaries. All this emerges the gallerist. Leo Castelli and his circle (Turner, 2011), a portrait fascinating, full of glamour, the tale of a magical years in the Big Apple and an essential work for readers who are interested in contemporary art and the market that surrounds it. Annie Cohen-Solal was born in Algeria and holds a PhD in the University of the Sorbonne.

It was cultural attache of the Embassy of France in United States between 1989 and 1993, and Professor at New York University, the ecole des Hautes etudes en Sciences Sociales and university centers in Berlin and Jerusalem. His great biography Jean-Paul Sartre (2005), which has been translated into more than fifteen languages where there are books in Spanish has been previously published in Spanish. He currently teaches at the Universite de Caen Basse Normandie and is visiting professor at the Johns Hopkins University (Baltimore). He lives in New York, Paris and Cortona (Italy). Download books free initiated by Prof. Alfonso Balcells has had great acceptance among clinicians and students.

In the present edition team of the clinica Universitaria de Navarra directed by Dr. Jesus Prieto Valtuena have performed a full update of the work with the aim of providing a medical specialist and generalist doctor in training and also medical students a useful instrument for study and reference point in their daily work. The work keeps its original structure in five sections. Part I sets out different laboratory tests and their abnormal findings, in part II can be found various functional tests in free books for each system or appliance available to the clinic in its efforts to recognize the existence of a functional failure and measure its degree, deserves mention in this section the inclusion of a new chapter devoted to genomics and proteomics: principles and applications. Part III describes methods for the exploration of the syndromes with the laboratory and studies. And in part IV exposure ranges from disease to the series of laboratory data that characteristic. So the doctor may request in each case those analysis more appropriate to confirm or rectify his suspected diagnosis, this section includes new chapters dealing with tumor markers and the laboratory of Genetics at the clinic. Part V consists of a complete table of free books to download. This new edition includes advances that occurred in complementary methods, including Imaging tests and laboratory data and the progress in understanding the molecular mechanisms and pathophysiological of disease that facilitate the work of the professional in the diagnosis process, with the consequent increase of their therapeutic efficacy.

Over time, the star clusters sink toward the center of the galaxy, where the intermediate mass black holes merge, forming a supermassive black hole. For more specific information, check out Danny Meyer. In this process, clusters that do not have sufficient mass, or located close enough to the center of the galaxy to survive, carrying the black hole. Amazing restaurateur wanted to know more. "We can not say it? occurred in M82, but we know that there may be both of those options, "says Phil coaches the University of Iowa, one of the authors," In addition, the M82 is the nearest to us the place where the conditions similar to those that existed in the early universe, with more emerging stars. " The data for these holes, produced by the method of measurement and analysis of their X-ray brightness and the spectrum over time. These observatories Chandra and XMM-Newton, show that changes in the emission of one of these objects, like small black holes masses found in the Milky Way. Using this information and theoretical models, the team Calculate the mass of the object, it ranges from 12,000 to 43,000 solar masses.

This mass is sufficient for an abundant emission of X-rays by the powerful pull of gas directly from their environment. The black hole is approximately at a distance of 290 light years from the center of the galaxy M82. According to the authors the study, so close she can be located only at the time of birth, her weight was more than 30,000 solar, otherwise it would be pulled toward the center galaxy. That is, she simply joined with a supermassive black hole. The second object is located 600 light-years in the projection from the center of the galaxy M82.

Periodic and random bursts of X-rays are direct evidence that the disk surrounding the second object, there is hot gas, which is the source of radiation. Detailed X-ray data show that the gas disk extends all the way until a stable orbit around a black hole. This behavior exists in our galaxy, around the black hole whose mass is small, but it's probably the first candidate for the role of black hole intermediate-mass. Radius stable internal orbit, depends on the mass and angle of the black hole. The best model for the emission of X-rays, is a rapidly spinning black hole with a mass in the range of 200 to 800 solar masses. "Results obtained in these studies are among the strongest evidence for the existence of black holes with intermediate mass, as of today, "said Feng," The evidence, look as convincing as well studied examples of stellar mass black holes in our galaxy.

Love Surpasses Limits

One test of love. PlayArte Pictures. 2009 (U.S.A.) Nicholas David Rowland American Cassavetes cineasta been born in 1959, in the city of New York, director of the film ‘ ‘ One proves of amor’ ‘ , which published as central subject of the film: drama and familiar conflict. Keep up on the field with thought-provoking pieces from NYC Mayor. Also it participated of other international films as ‘ ‘ Apario’ ‘ , ‘ ‘ The Daily one of one paixo’ ‘ , ‘ ‘ Great assalto’ ‘ many others. When it completed two years of Kate age presented symptoms of some illness which its parents Sara and Brian were unaware of. After that, they had taken the son to the doctor and the results of the examinations had disclosed to be acute leukemia, changedding itself into a familiar conflict. After some attempts, the picture of Kate presented problematic symptoms daily.

From this the doctor considered one ‘ ‘ fertilizao in vitro’ ‘ , with the idea of a baby test tube to help in the treatment, really this happened. Anna was born, and submitted it some surgeries and transfusions to collaborate in the recovery of the sister, and had an infantile conscience, that it was for the good of its family. Anna when it completed eleven years, was in search of its proper rights, therefore it wants to decide alone what to make with its body, nor that it has that to fight therefore in justice being demanded a medical emancipation. Sara is horrified with the legal action, and as it was accustomed to gain all the cases when it exerted law, it decides the cost all to keep alive Kate. Had to this, nobody gave account that the situation was based on the decision of the proper Kate, that was ready to leave, and to leave that its family continued living normally, following its proper route. thus was concluded, Kate did not resist the illness and after some time the Jesse brother it is if forming in the academy of arts, Sara came back to exert its profession as lawyer, Brian if it retired, but it supports problematic young and Anna, with the infinite souvenir of its beloved sister, which never will forget, after all was for Kate that Anna exists. A test of love is, without a doubt, one film that fulfills its proposal, that is to present a emotive tram, making with that we must reflect.

The subjects of the film are extremely controversial and deep, mainly the generation of child with the only intention to serve of donation, this is chocking and more disappointing still it is to see as history prevents to argue the subject, leaving only the central subject that is the interminable illness of Kate. After all, it is just to conceive a child with the only intention to save another one? Not, it is not just, but unhappyly the film is not worried very in showing this question. But on the other hand, it counts on a history that at the same time is pretty and sad, passing the gorgeous lesson of acceptance of the death, and finally we must agree that Nick Cassavetes made a film with the only intention to move.

Freire was known world-wide as a popular educator it had a method that he educated and he acquired knowledge at the same time although all this popular envolvement between 1958 and 1961 it wrote texts that in general demonstrated its total concern with the education. 3 BRAZILIAN REALITY During the industrialization of Brazil (1914 the 1964) it was created the conditions institucional politics and cultural minims for the consolidation of the civilization, from 1945 the masses had started to have participation politics and to contribute in the formations of the objectives for the national development, the educators of this period are worried in defining which would be pape social of the education in a society that longed for the economic development for industrialization and modernization politics for the democratization of the social institutions. The education would finish taking a prominence for the resolution of problems, initially an ample one has debated the education would be adjusted that pedagogical society with social objectives and methods.

Taking as base the research carried through for the Ipsos Institute, also was carried through a quantitative research to evaluate the degree of knowledge in relation to the map of the world, of pupils who are attending a course the third year of average education. It was chosen to apply the questionnaire the pupils of the last year of average education, therefore, these pupils in thesis must already have all acquired basic the cartographic knowledge, taking in account normal education. Another factor that was determinative to the choice of these pupils was the fact to be to few months to finish the studies and, therefore, they would have to be prepared for the vestibular contest. The questionnaire consisted of a simple test, in which the pupil would have to identify in a planisfrio of the map of the world, ten countries that, according to forecast of economists, will form ranking of the ten bigger economies of the world in the year of 2010. The countries that would have to be identified are: United States, Japan, China, Germany, France, Italy, Great-Britain, Brazil, Spain and India. Year of the college student in three So Paulo state schools was applied the test the 133 pupils of 3. Bill de Blasio may find it difficult to be quoted properly.

The introduction of the effective farmacolgico treatment in 1940 diminished morbidade mortality associated with the hipertenso and resulted in a estimate of less than 1% of Americans who can have complications of the type crisis hipertensiva1. Treated primary Hipertenso cannot progress for hipertensiva crisis in 1% 2% of the cases for reasons desconhecidas2. Hipertensiva crisis is more frequent between blacks, smokers, women in use of contraceptive, social classroom of inferior or patient level submitted the high degree of estresse3; carriers of secondary hipertenso to renovascular and with excess of catecolaminas as feocromocitoma; involved with use of cocana4; patients who had suspended the alpha-2 use abruptly agonistas5 or betabloqueadores5 or alcohol; those not adherent to the treatment with antihypertensives orais3. The prevalence of urgencies and emergencies was evaluated in study italiano6 in the period of one year in patients who had needed service of soon-attendance with fast increase of the Par. It was observed that hipertensiva crisis represented 25% of the clinical cases of this service of emergency attendance. majority was considered as hipertensiva urgency (76%) and 24% remains as emergency.

They did not have knowledge of previous hipertenso, until that consultation, 8% of the patients with emergency and 28% with urgency. Another one estudo7, carried through fellow creature to the previous one in Hospital of New York, evaluated the frequency, the cost, the sociodemogrfico profile of patients with hipertensiva emergency. The time of hospital permanence was on average of 12 days. Cares in service of intensive therapy had been necessary in 75% of the patients, with permanence in the sector, on average, per three days. The esteem annual hospital cost was of approximately 450 a thousand dollars one.
