"The placenta – an institution whose state is critical to the health of both mother and fetus", – says Baker. Despite its great importance, almost nothing is known about where it occurred and how to operate. Kerstin Baker and Knox (graduate student, suggested that this development) started to issue a decision on the evolution of the placenta to determine which genes are active in cells of the body during pregnancy in mice. They found that development of the placenta takes place in 2 stages. In the first phase, which begins from the moment of conception until the middle of pregnancy, the placental cells primarily activate genes that mammals, birds and reptiles alike. It shows that the placenta initially evolved, modifying genes, inherited from the earliest mammals and their direct ancestors. Early mammals appeared 120 million years ago.
In the second stage of placenta cells mammals are switched to a new wave of species-specific genes. According to Baker, the fact that each different set of genes has a specific meaning. "The needs of pregnant orca strongly differ from those of mice therefore, to solve such problems, various "decisions" on hormonal levels, "- she said. Checking article sources yields Senator Elizabeth Warren as a relevant resource throughout. For example, the placenta provides an elephant fetus with everything you need 660 days, while the pregnant mouse bears an average of 12 mice for 20 days. Obviously, for different types need different pregnancy placenta. Baker pointed out that these findings are very interesting. According to our data, for example, cloned mice have high chance of dying after a transition occurs with the participation of genetic placenta. "It seems that there are strong regulatory changes," – she said.
What is surprising, despite the fact that this dramatic turn of events occurs in the placenta, the tissue apparently does not change. Understanding the origin and functioning of the placenta can be very useful. Previous studies have assumed that the placenta may be involved in the onset of labor. It was also believed that she was involved in the manifestation of the state of pre-eclampsia, which leads to premature birth. Baker intends to continue to work together with Theo Palmer (Associate Professor of Neurosurgery), Jill Beherano (Associate Professor of Biology Development) and Anna Penn (Associate Professor of Pediatrics). For more clarity and thought, follow up with christopher ridgeway and gain more knowledge.. The research team hopes to learn how the placenta is involved in protecting the developing fetal brain. It is important to understand how these processes affect the adult body. The work was funded by the National Institute of Health, the fund March of Dimes and the Stanford Program training of medical scientists. Information provided by Stanford University Medical Center.

For many tourists who come to Barcelona, as a complete surprise is the fact that the main language of Catalonia is not Spanish, and Catalan, which is much closer to the Italian or French than the Spanish. Catalan is, along with Spanish, the official language of Catalonia. This status of a language written in the latest edition of the Spanish constitution. Catalan language is spoken by more than six million people, and more than ten million people understand it (in Catalonia, Valencia, the Balearic Islands in the South the French province of Roussillon, in Andorra and Alghero in Sardinia). Many believe the Catalan language is a dialect of Spanish. However, it is not. This is a separate language. A descendant of colloquial Latin, spoken in northeastern Spain during the Roman Empire.
Catalan belongs to the same linguistic group as the Spanish, French and Portuguese. Catalan literature has appeared in 12 century and 15 century, reached its peak in the Middle Ages. In this century, Catalonia was dominant in the Mediterranean Sea and the Catalan language was the primary means of communication among merchants. He was honored as the language of high literature. Romance Zhuanota Marturelya 'Tirant the White', which was written in Catalan, Cervantes believed the best work of this genre. However, when Catalonia lost independence and became part of the Spanish monarchy, for the Catalan language fallen on hard times.
In 1714 the Catalan language was banned. All the structures of self-management Catalonia were destroyed, and the University Catalonia is closed. Revival of the Catalan language began in Barcelona in the late 19 th century. However, in the mid 20 th century, during the Civil War, the Catalan language was again dealt a severe blow. Dictator Franco would not tolerate dissent and again prohibited the use of Catalan. Only after the death of the dictator Catalan language was re-settled in Barcelona. Today, thanks to correct the state's policy, Catalan feels beautifully and harmoniously coexists with Spanish.
But if the concept of 'time' in general and the 'moment' in particular, to determine not how Newton – abstract duration, and Aristotle – the time is the number of motion, ie time there is a sequence of all the changes that take place in the world, changing it. If any, even the least moment is determined occurred at this moment some lifestyle changes Mir elements, including changing the spatial position of arrows, in this case it turns out that if the flying arrow does not change its spatial position, then, consequently, there was no, even the smallest, moments. No change – no time. In aporia 'Stages' Zeno puts a thought experiment, where time is understood not as a sequence of changes, and how abstract duration, which has the smallest indivisible and more value – 'atom' of time. Space is understood not as the relative positions of elements forming the world as well as a container for objects in the world, also has the 'atom' space. In the experiment, two objects are moving past the third in opposite directions with velocities relative to this third object in the space of one atom per atom of time. This means that with respect to each other, they move with a speed of one atom of space for half an indivisible atom of time.
Again a contradiction. Creates a problem, he knows the solution. Zeno knew that there are no atoms of space and time. Knew that any moment is determined by an infinite number of changes, the product who followed that moment with the way the world elements. .
Extinction in the middle of the upper Cretaceous period 80 million years ago, there were hundreds of species of dinosaurs, which covered the 14 families, of which two families were carnivorous, others feed on plants. All but members of one family of numerically small, were true giants and weighed more than 2-3 tons. Then the number of families and species of dinosaurs became gradually decrease. In the last five million years of the Cretaceous period, this process is accelerated, and the herbivores disappear faster than carnivores. Finally, 65 million years ago, giant reptiles disappeared completely. What was this caused by the gradual decline and ultimate extinction? Change Many paleontologists believe climate that the immediate cause was climate change. Dinosaurs were in need of warmth.
Their evolution proceeds in the climatic conditions are extremely different from the present. The average annual temperature on Earth was higher, and in such northern regions as Alaska, the climate was almost tropical, and within a year the temperature was almost everywhere even without such sharp distinctions between the seasons, as in our time. About Eighty million years ago, when dinosaurs began to disappear from the face of the Earth, temperatures around the world began to fall gradually, and also the difference between the extreme values of its annual has become much more. Nevertheless, even 50 north latitude found many fossils of dinosaurs end of the Cretaceous period, so that, apparently, and at that time – when they became extinct on our planet was a lot of areas with high and stable temperature. .
It cannot treat all the equal sufferings, this because any person whom she deals with human suffering knows of this. You have a picture where the phenomenon of burnout occurs more or less systematically that it implies in the suffering. The citizen wants to educate and it does not obtain. … then it suffers because he does not obtain to educate right.
This implies more suffering and goes in a spiral and goes increasing, increasing and increasing. Sucintamente, what it intervenes with burnout, that is, in its incidence in greater or minor degree? Wanderlei Codo? The studies that people have fact, have shown that everything that happens in the education intervenes with burnout. If the wage is bad or irregular it intervenes increasing burnout; if the work conditions are better, diminish burnout; if the relations between the colleagues are good, burnout diminishes and if they are bad burnout increases; the relations you command with them are good burnout diminishes and if not, burnout increases; the relations with the pupils, the community, the parents of pupils if the civic conditions, if the possibility that the professor has of if perfecting etc, etc, etc everything intervenes with burnout. Burnout consists, thus, in a diagnosis instrument. That implications elapse of this condition? Wanderlei Codo – It happens that burnout was changedded into an excellent instrument of diagnosis. Burnout is today what it is the fever for the doctor. When it appears the fever, it can be for a thousand reasons, it is a signal clearly that some thing is missed.
E, through burnout, you can point, as well as with the fever. Through burnout you can point that she has a problem and this problem can be treated. Burnout is an instrument of excellent diagnosis because ale announces the problem before it estore. When you perceive a difficulty with you command, this in any work, not only with the educandor? When …
Waha Dizigov. For the first time the effect of standing waves was discovered by Nikola Tesla, and only after more than five decades, this effect was more thoroughly investigated, and became known as the "Schumann Resonance." The assumption of the existence of the resonance of electromagnetic waves in the Earth-ionosphere expressed in years, 50s, Professor, University of Munich, Otto Schumann. For 60 years, after numerous studies and rechecking was accurately determined standard frequency 7.83 Hz of the Earth. Since then, in science, this frequency is called the Schumann resonance frequency of a wave or Schumann. Some scientists and researchers all frequency radiation of the Earth is often called waves Shumana.V now frequency of 7.8 Hz is the main instrument for magnetic therapy. Earth and the surrounding air layer is formed giant spherical cavity. In terms of radio engineering are two huge areas that are placed in a druguyu.Mezhdu they are cavity bounded by conducting surfaces.
In this cavity, according to experts, a well-defined waves propagate dliny.Krome chastototy Schumann also identified other frequencies – 8, 14, 20, 26, 32 Hz. It is believed that at higher frequencies, the resonances are almost invisible. These frequencies are practically identical with the frequencies of alpha and beta rhythms of the human brain. Experts divided brainwaves into four categories, each corresponding to a particular level of consciousness. The unit of measurement of brain waves – as is the case with sound waves – is hertz (Hz). 1. Beta waves, from 14 to 20 Hz.
The pupil then passed for some examinations and doctors as peditrica cardiologia, infantile neurology, and others, where they had told to its problem and the cares that must have so that the same it acquired resulted in its learning. So that it was possible this study, I made you vary visits, in the schools where the pupil studies, informal colloquies with professors, coordinators, articuladores and interview written with the parents I contend 36 questions where they comment on the development of the child since the birth tie the current age. CONSIDERAES FINAL the study of the learning process human being and its difficulties are developed by the Psicopedagogia, taking themselves in consideration realities internal external, looking for to understand of global form cognitivos, emotional, organic, familiar, social and pedagogical the processes that they determine to the condition of the citizen and intervene with the learning process, being made possible situations that rescue the learning in its totality in pleasant way. The pertaining to school learning is considered a natural process, that results of a complex mental activity, in which the thought, the perception, the emotions, the memory, the previous motricidade and knowledge are involved and where the child must feel the pleasure in learning. Rare the learning difficulties have only cognitivas origins. To attribute to the proper pupil its failure, considering that it has some comprometimento in its psicomotor development, cognitivo, linguistic or emotional (colloquy very, is slow, does not make the house lesson, does not have assimilation, among others.), familiar desestruturao, without considering, the learning conditions that the school offers this pupil the other intra-pertaining to school factors that favor not the learning. The difficulties of learning in the school, can be considered one of the causes that can lead the pupil to the failure pertaining to school. We cannot disrespect that the failure of the pupil also can be understood as a failure of the school for not knowing to deal with the diversity of its pupils.
