American State

According to scientists, the study will give a clearer idea of what climate change can be expected with accumulation in the atmosphere of carbon dioxide caused by industrial human activities. Because of global warming are less migratory birds fly south for winter spent watching the life of the Pacific black geese in Alaska, biologists have concluded that these birds have in recent years rarely solved on long flights for the winter to the shores of the Gulf of California. This behavior of birds, scientists explain the fact that now the climate in Alaska has become softer, and the once barren lagoon of the American State each year become more and more attractive: the winter is getting warmer, start grow plants that can feed the birds in winter. Over the past 30 years the number of geese who have refused to trip south increased from 4 to 30 thousand, and it is about 30% of the population of this species of birds. Warm weather in the area of habitat geese has reduced the amount of ice, there was more food for birds in the form of sea grass. The warming of the planet forcing birds to abandon long-distance flights for the winter in warmer climates.

In addition, as they note, wintering in the north, the birds may return earlier than the other to breeding grounds, and consequently, faster raise offspring. Confirmation – increasing brood of birds remaining in the winter in Alaska. Scientists offer to turn the Sahara into a tropical forest researchers presented a new project to combat global warming which involves the conversion of the Sahara desert to tropical forest.

A New Class Of Black Holes

New data obtained by X-ray Observatory Chandra and XMM-Newton, confirm that there are two medium-size black hole in our neighboring galaxy. These holes, so far managed to avoid falling into the galaxy center. They can be example of the "seeds" from which are formed supermassive black holes in galactic centers, including the Milky Way. For several decades, scientists have strong evidence for the existence of two different classes of black holes, holes with a mass of magnitude, about 10 solar masses of supermassive located in the centers of galaxies, whose mass varies from hundreds of thousands and up to billions of solar masses. But is there a black hole intermediate-mass? The mystery still remains unsolved.

Evidence for the existence of these objects was controversial, and there was no convincing arguments that there are intermediate black holes in the galaxy. Recently, a group researchers found in X-ray data, the signature of medium-mass black holes in the galaxy M82, located 12 million light miles away from Earth. "This is the first discovery of two black holes, the average weight in one galaxy, "says Hua Feng of Tsinghua University in China. Scientists led two papers describing the results of the study. "Their location near the center of the galaxy may contain information about the origin of large, supermassive black holes at the centers of galaxies. " One possible mechanism for the formation of supermassive black holes, suggest a chain reaction of collisions of stars in compact star clusters that leads to the accumulation of very massive stars that are in the process of decay, forming a black hole intermediate-mass.

Earths Magnetic Field

Humanity is facing a very long time to magnetism and electromagnetism. But the study of these phenomena thoroughly, until the end people could not, because all experiments ever conducted on the ground, were held without fields of the Earth. It was argued that the effect of field of the Earth "… very little, and we ignore it …." That is only true if this assertion, if the value is discarded, which was not measured and do not understand? Let's hypothetically an experiment where the effects of extraneous fields do not affect the course of this experiment: take two identical circuit and pass through one of them current. Contour within which the current passes, will create his field, spreading it in space until it reaches the second circuit. Ie the second circuit will respond to the field created by the first circuit (different in magnitude but opposite in direction). Thus, there are two objects with equal but opposite to the location of the poles.

Do not forget that these two circuits is not affected by other fields except the fields produced by them. And in this case they will be attracted. Phenomenon resonance observed in terrestrial conditions, these circuits did not appear. But it emerged the phenomenon of magnetic attraction – and under the influence of this force were fixed objects to each other. Magnetic field have all the items in Universe – the planets, stars, to microscopic particles (atoms). Magnetic field is the ability of subjects to influence one another by pulling or pushing away.

Bologna University

The problem number one in any country is education. And in Spain the subject walks scrambled from different instances that affect all levels of education, including University. It is time to think about education and do it thoroughly. The organic law of education in Spain leaves the door open so that the autonomous communities cut hours of subjects like philosophy, opening some communities leverage as Valencia to reduce his schedule; the process of Bologna University convergence will bring to Europe adocenada University, in which quality just by measuring the amount. The number of students has become decisive for determining the quality of a commodity or a postgraduate degree, and there is no room for specialization. One thing is know a lot of little, know each time more than less and end up knowing everything about nothing; something very different, know only generalities, because, they say, thats what is preparing to adapt to any market need. This is the message of Bologna, assumed with fervor by retrograde and progres.

We then quejaremos of savage neoliberalism. The new airs insist on preparing students to develop skills in the sciences and Humanities as well as technical studies. The old debate about whether educating consists in form or report has gone out of fashion, because you already know any teacher or professor that theirs is to prepare competent girls and boys. Competent, for what? To perform jobs assigned by the labour market, it is clear. Therefore, if there is a plan of any educational level or a postgraduate studies, paragraph longer and more complicated shall not which refers to the contents of the materials, but which relates to competencies. Competence is a set of knowledge, skills and attitudes necessary to carry out an occupation and produce a definite result. I consulted a colleague of pedagogy, and with a good dose of irony, he gave me an example: someone is competent to make a bed when you know what is a bedspring, a mattress, what they are the savannas, realizes how it is best to place them and also feels something important enough as to try to leave them well, without wrinkles and without that the embozo remains uneven.

Appropriate Control

We have spoken on previous occasions, of the impact of the complaints of customers and users (see related news by clicking here). This time, we will focus on a specific users type: students. Internet is currently a medium very used to register criticism from users, and more still when it comes to young users whose fundamental tool in day to day is the computer. And is that it needless to say that the youth of today handled to perfection the new technologies, and used the network, an average of two hours a day for leisure, without taking into account time spent you by obligation either for reasons of work or study. Within this area student, formulated complaints and criticism through this medium, it seems the perfect procedure.

These views, may have different origin, as poor relations with certain teachers, or complaints by the notes of the exams. Know who made these comments, can help us to solve the problems and avoid arising out a string of a comment, vast views of the same type. And it is that it is human tendency, partnering most to pronounce on the downside you on good. If the complaints are unfounded and anonymous little we should do, however, there are many occasions in which complaints can be productive. This is the case, for example, of the comments with respect to administrative shortcomings of colleges and universities, such as the improvement of the conditions of classrooms or lack of space in the libraries. It is important that institutions reinforce the positive aspects acknowledged, but it is even more important to correct the deficiencies.

A good image is essential to exercise leadership and confidence. When a student chooses the University that is going to pursue their studies, previously performed a trace not only the information about the own career, but also information that can provide other users with respect to methodology, teaching staff i.e. on more personal aspects of the entity. If the image provided by the comment made by students is positive, this constitutes a strong argument, so University future opt that studies Center within its alternatives. On the contrary, if this information is negative, they doubted not dismiss an institution, since the educational offer in our country is very wide. Therefore, we invite those responsible for subjects, associations of students, directors and all members involved in education, that attend these opinions and devote some time to determine the most practical solutions to exercise some control over all these comments, positive or negative, since their knowledge, not only facilitate the work of solving the problems which may arise environment to them, but that will help us build a positive reputation.
