¿Cómo se formó la Tierra?

La Tierra es uno de los ocho planetas del Sistema Solar, el tercero en el orden de las distancias al Sol y el quinto por su tamaño. Dista del Sol 149.476.000 Km. y tiene una atmósfera intermedia entre las de Venus y Marte, compuesta principalmente por nitrógeno y oxígeno.

Establecidas sus principales características y disposición con respecto al Universo, hoy nos preguntamos ¿cómo se formó la Tierra?

Teorías sobre el origen de la Tierra

Se han propuesto dos tipos de teorías sobre el origen de la Tierra según se consideren situaciones catastróficas o no (también llamadas respectivamente binarias y unitarias). En las teorías binarias o catastrofistas se plantean explicaciones en las que se incluyen fuerzas externas al Sistema Solar; donde intervienen otros objetos celestes además del Sol, mientras que en las teorías unitarias, no.

Las teorías unitarias, denominadas también naturales o evolutivas, sostienen que los sistemas planetarios son parte de la historia evolutiva de algunas estrellas.

Estas explicaciones se realizan de dos formas: una explicación es la formaciónsimultánea del Sol y los planetas, mientras que la otra plantea que el sistema de los planetas nació del Sol. Es decir, que el Sol se originó primero y, de éste, se originaron luego los planetas.

Las teorías unitarias son conocidas como hipótesis nebulares y fueron propuestas por el filósofo alemán Inmanuel Kant (1.724–1.804) y el matemático francés Simón Laplace (1.749 – 1.827).

Explicación más aceptada por la ciencia

La Tierra que conocemos tiene un aspecto muy distinto del que tenía poco después de su nacimiento, hace unos 4.470 millones de años. Entonces era un amasijo de rocas conglomeradas cuyo interior se calentó, fundiendo todo el planeta.

Y es que los planetas del Sistema Solar, como la Tierra, fueron creados por las colisiones entre planetas enanos en órbita alrededor de esta estrella central (el Sol) recién nacida. En las colisiones, los planetas pequeños se funden y forman astros cada vez más grandes

6 Steps to Create your own Forex Trading System

The main objective of this article is to guide you through the process of developing your own trading system to operate in Forex .

Although devising a system may not take too long, if it can take a long time to prove its effectiveness. So, you must be patient, because in the long term a good trading system can generate you a lot of money.

How to Create your own Forex Trading System
Step 1: Time frame
The first thing you need to decide when creating your trading system is to know what kind of operator you want to be. Do you want to be a 1-day or 1-hour trader? Would you like to observe graphics every day, every week, every month or even, every year?

How long would you like to keep your positions open? .

Answering these questions will help you determine what timeframe to use in your operations. Although you can also analyze charts with different periods of time, this will be your main time frame, which you will use when looking for signals to open or close positions.

Step 2: Choose indicators that help you identify a new trend
Since one of our objectives is the identification of trends as soon as possible, we must use technical analysis indicators that can achieve it. For example, moving averages are one of the most popular indicators that operators use to identify trends. Two moving averages are usually used (one slow and one fast) and the rapid crossing to the slow above or below is expected. This is the basis for what is known as a mobile average crossing system .

Of course, there are many other ways to find trends, but the moving average crosses are one of the easiest to achieve.

Step 3: Find indicators that confirm the trend
The second objective for our trading system for Forex is that it has the ability to avoid false signals and thus avoid falling into false trends. The way to do this is to make sure that when we see a signal of a new trend, we can confirm it using other indicators.

There are many indicators that confirm trends , such as: MACD , Stochastic and RSI .

As you feel more familiar with the indicators, you will find some that you will prefer over others and that you can incorporate into your system.

Step 4: Define the level of risk
When developing the system it is very important that you define how much you are willing to lose in each operation . Very few like to talk about losing, but in reality, a good operator thinks first of what he can eventually lose before thinking about how much he can earn.

The amount of money one is willing to lose is very different from one trader to another. You have to decide how much space is enough to allow your operations to breathe, but at the same time, do not risk much in a single operation. In subsequent lessons we will explain more details about money management. The money management plays a big role in the risk that you must give to each operation .

Step 5: Define inputs and outputs
Once you have defined how much you are willing to lose in an operation, the next step is to discover where to place the closing of an operation to obtain the maximum possible benefits .

Some people like to enter as fast as they can in a trend when their indicators give a good signal, even when the candle has not closed. Others like to wait until the candle closes.

According to my experience I think it is better to wait until the candle closes before making an entrance. I have been in many situations where I am in the middle of the candle and all my indicators fit, only to discover that at the close of the candle, the operation turned against me.

But you can have a different opinion when you have some experience. It really is just a style of operation. Certain people are more aggressive than others and you should go slowly realizing what type of trader you are.

For closures or exits from the market, there are different options. One way to close is to place a stop loss , this means that if the price moves for your favor in "X" amount, you move the stop loss for that "X" amount.

5 PROMISES THAT EVERY STRONG WOMAN MUST DO

La fortaleza a menudo nace del dolor y del sufrimiento. Las mujeres fuertes, durante muchos momentos de sus vidas, se sintieron débiles e indefensas. La fuerza que llevan dentro de ellas ahora, no nació de la nada. Esa fuerza se cultivó, nutrió y creció.

Esa fortaleza es el resultado de semanas, meses o incluso años de permitir ser tratada como menos de lo que vale, por miedo a reacciones adversas o estar sola. Cada mujer fuerte se ha ganado esta fortaleza y tiene cicatrices que no siempre son visibles a simple vista.

Hazte promesas, éstas sirven para recordarte que nunca más debes permitir regresar a la mujer débil que alguna vez fuiste.

PROMÉTETE NO RENUNCIAR A PARTES DE TI PARA NO MOLESTAR A OTROS

Una mujer fuerte ha enfrentado el desafío de renunciar a partes de sí misma que aprecia para no molestar a alguien que no la aprecia como un ser humano completo. Renunció a sus intereses, a sus amigos o familia, a su trabajo o sus ambiciones, por lo tanto, prométete no volver a permitir esto nunca más. 

Eres una persona completa y nunca debes permitir que otra persona te divida en partes y elija las que considera aceptables.

PROMÉTETE NO ESPERAR QUE LA GENTE CAMBIE

Esperar que alguien cambie y te ame de la manera correcta es un error que nunca debes volver a cometer. Las personas sólo cambian si quieren hacerlo. Ninguna cantidad de amor en el mundo podrá transformar a alguien en algo mejor si no quiere. 

Esperar a que alguien cambie sólo traerá desilusión y frustración, y todos sabemos que no vale la pena preocuparse por tratar de amar a alguien que no quiere ser una persona mejor.

PROMÉTETE NO RECIBIR MENOS DE LO QUE MERECES

Toda mujer fuerte pasó por un período de su vida en el que pensó que veía algo bueno en alguien, y se permitió sufrir porque pensó que podía cultivar esa bondad. Al final, descubrió que no se podía esperar una flor cuando todo lo que nace son espinas. 

La fortaleza llega cuando una mujer se da cuenta de que se merece alguien que sea bueno por sí mismo, sin necesidad de ir a buscar esa bondad. Prométete que esto nunca volverá a suceder.

A talent that looks for the different

Four young Latin Americans who are currently studying in Spain explain why they decided to take the leap

"Long live the winter!" Exclaims Leonel López, a 31-year-old Cuban who studies in Madrid, "It's nice to live less than 28 degrees, to have stations ...", responds Joan Sebastián, 25, from Colombia, who studies for Being a physical trainer, María Brollo, a Brazilian PhD student in physics, says: "Then, when it snowed a few days ago, you had to hallucinate." Jenifer Márquez, from Venezuela, a Fashion student, laughs and replies: "Well, I have Very bad this cold, and more in spring. "These four students just met for the photo shoot and to talk about their experience, share views and experiences and continent of origin, but above all have in common the key to Be here: Spanish.


It is therefore easy to build bridges between the two continents. Spain continues to be an attractive destination, despite the crisis, to train in subjects where the country stands out. Science, fashion and sports call the public. Medicine, technology and science, as far as research is concerned, continue to be a reference. The arts too. And, of course, highlights the world of big data, the architecture of mobile applications and the Internet of things, which is launched in small and medium enterprises. In addition to sports, with the referent of the great football clubs, which attract those who want to specialize in management, in the most business-oriented part, or train as a physical trainer.

Also in the doctorate programs talent is imported. The humanities, from the most central and large universities, such as those in Madrid, to the smallest ones, such as Valladolid, receive students from Latin America every year. "It's a very demanded area," says Salomé Berrocal, professor at the University of Valladolid (UVA). "In some countries like Ecuador, Mexico ..., in many countries in Latin America, being a doctor is like having a noble title. They are well valued and earn a significant salary, "he says.

"Having a master's degree, an official degree, is a brutal qualitative leap for Latin Americans," says Graciela Padilla, professor at the Faculty of Information Sciences at the Complutense University. For almost a decade he has coordinated university master's degrees and own degrees. "The students coming from Latin America bring a lot of value: they are very hard workers, most of them eat the Spaniards, because they have a very good university education in their countries and in second and third language they are almost native", he assures. And what do they do when they finish? "Many want to stay," says the professor of the Complutense. The exception is young Ecuadorians because the scholarship agreement with which they come to study is usually well tied. "To avoid the flight of talent, the Government of their country guarantees accommodation and subsistence allowance and pays for their studies, but they sign that they will return as soon as they get the minutes, they are very strict," she says.

Fulfill a dream
Jenifer Márquez (42 years old) traveled to Spain from Venezuela and stayed, although her goal was not to study first, but "to spend a season to see what opportunities could be found in the country". In the capital of Spain she married and had two children and this year she has been accepted to study the Fashion degree at the School of Design in Madrid (ESD), a public body of the Community of Madrid where degrees, masters and postgraduate courses are taught . "This is fulfilling a dream. First, because being a public school it is affordable to enroll; second, because it is very difficult to enter, and third, because it is about studying in a cosmopolitan, modern city, where your creative ideas have no limit, "says Márquez.

With the same idea landed Leonel Lopez, grandson of Galician and student of the same school but in the master of interactive design, ie, creation of apps, architecture and web usability, and so on. "I'm passionate about technology, interacting, and I like to be part of something that you design and work, that catches me," he says. "Spain is full of start-ups and entrepreneurs and it's interesting the number of events you can attend to make contacts, learn and make friends, for example, the Google Campus." On these occasions he has received various proposals to join projects underway and about to be born. "We are receiving various awards and mentorships, as in the Think Big program of Fundación Telefónica," he says.

CFDs on Commodities

What are CFDs?
A Contract for Difference (CFD) is an agreement made between the buyer and the seller of a specified asset. This agreement states that the seller will pay the buyer the difference in price between the asset’s value at the time the agreement was made and the asset’s value at present.

CFD trading is one of the most popular options for traders because you’re trading on price movements of an asset, without actually having to buy it.

Why trade CFDs on Commodities?
CFDs offer you easier and faster access to the commodities markets. As a result, it provides you with flexible trading opportunities that have great potential to boost your investment portfolio.

With FXTM, you can choose to trade the following three CFD commodities:

UK Brent (Spot)
US Crude (Spot)
US Natural Gas (Spot)
Competitive Trading Costs
Our CFDs on Commodities are designed in a way that gives clients the same trading benefits as if they were trading instruments on the actual commodities exchange, but without the costs associated with connecting to the actual exchange.

Thanks to leverage, CFDs are attractive to traders because they offer an opportunity to participate in the financial markets with a small initial investment. Traders use a smaller portion of their own capital when opening a position, which opens the doors for potentially bigger returns. That said, it’s important to remember that leverage carries the same potential to increase losses as it does to boost profits.

Fast Execution and Deep Liquidity
Our CFD commodities are tradable with both instant and market execution. FXTM’s commitment to efficient order execution has ensured deep liquidity with many providers, and super-fast execution for more precise trading.

Things to consider when trading CFDs on Commodities:
Whether you go short or go long, the same rules and margin requirements apply when trading CFDs.
The margin requirements for CFDs are lower than they are for the underlying asset. Click here for our contract specification details on CFDs.
Since you can take both short and long positions with CFDs, a falling market retains the same risks when it comes to incurring losses but it can also offer potential profit-taking opportunities.
The benefits of CFD trading is clear, but always remember that all leveraged assets have similar levels of associated risks and CFDs are no different.

Foreign students fear Trump

EE business schools are concerned about the loss of students due to the xenophobic wave and the obstacles to visasEE business schools are concerned about the loss of students due to the xenophobic wave and the obstacles to visas

The students do not like Donald Trump. And if they are from outside the United States, still less. They have left it patent, regardless of studying in that country. 75% of American business schools have seen how requests by foreigners to pursue their flagship program, the master in business administration or MBA for two years, suffered a clear setback. In the case of the one-year MBA, the drop was registered in half of the institutions. These are data from GMAC, the organization in charge of managing the compulsory examinations to enter the world's management schools, for the course that has just concluded (2017-2018).


In the rest of the master's degrees to which more foreign students traditionally attend (finance, technology and accounting), the decreases have also affected more than half of the training centers. "Recent political events may provide clues to the decline in demand," the institution said.

And although official education statistics still do not reflect these falls (the latest available correspond to the 2016-2017 academic year), those of study visas have shown a decrease of 17% in 2017. Not only that. American business schools recognize the cut. "There are decreases of up to 20% in the visas of foreign students," admits Mauro Guillén, director of The Lauder Institute at Wharton School. "Decreases that have to do with the fear of the xenophobic wave captained by the president of the United States and also with the obstacles to get a work visa once the MBA is over."


Carlos Murrieta, of Mexican origin and general director of Pemex Transformación Industrial, has decided to continue with his MBA in Spain. But the United States was his first choice when a year ago he began preparing his application process to three prestigious centers: Georgetown, Foster School of Business and Chicago Booth. Then began the threats of the North American president to North Korea, explains Murrieta by telephone from South Korea, a warlike tension that made that the executive made him change his mind and look towards Europe. "It influenced my decision to get to know other European schools." In Mexico, it is natural to go to the United States to receive postgraduate training, although more and more it tends to Europe for the quality of life and openness of its countries. The Mexicans in the United States do not seem to end, "he says. Mexico, but also Brazil or Peru have stopped exporting many students there for the benefit of Europe and Canada.

And, in fact, the migration policy of the most powerful country in the world has no sign of becoming more flexible. Different to. Therefore, international students continue without this destination to train in business administration. Also facing the academic year 2018-2019. A situation that impacts less in the big schools, Guillén appreciates, "although if the trend continues they could be affected", he predicts. Do not forget that international students contribute some 39,000 million dollars to the economy of the country.

The specialized publication in business schools Poets & Quants has compiled the latest data on next year. And insist on this fall. With the exception of the five leaders (Harvard, Stanford, Chicago Booth, Wharton and Tuck School of Business), most of the top 25 management training centers have fallen, especially the Stern School of Business (New York University), which loses almost 10 percentage points. and Columbia Business School, which ranges from 48% to 43% of foreigners in their classrooms. Of the next 30 in the ranking, 19 have reduced their international students, especially Mays (University of Texas), which has lost 40%, or the Terry College of Business (University of Georgia), where they fall by 32%.

, India and Mexico are, for now, the countries that are most reluctant to send students to the United States, but restrictions on visas, says Josep Franch, dean of the Spanish Esade Business School, will affect the recruitment of students from the great American schools in markets like Iran, Pakistan, Syria, Sudan ... And the second derivative, he continues, will be the difficulties of hiring graduates with foreign visas to work in New York, Chicago or Los Angeles.

Opportunity for Canada
American business schools are very concerned about the situation created by Donald Trump, Franch adds. The work options for international students are decreasing and the main competitors of the best business schools, London, Paris, Madrid and Barcelona ... are taking advantage of this anti-immigration wave. "Canada is also taking advantage. It is a golden opportunity to attract global talent, "says the director of The Lauder Institute.
