I think this is a very complex and delicate subject, I always hears about how the foreign people didn’t respect the rights of the native people, this is not only a problem in Chile, is the same in other countries like United States or Brazil.
First we need to understand this problem, the Mapuche Conflict (or Mapuche issue) is referred to the revival and reorganization of the Mapuche communities for autonomy and land reclamation since the return of democracy in Chile primarily through footage claimed and intimidating land owners and staff of these lands with armed or incendiary attacks. Their demands revolve around three areas: judicial independence (own right), the return of the lands, financial claims and cultural identity.
If we understand that these people don’t feel they belong to Chile, is hard to say is there is an easy resolution of this conflict. Moreover the politicians became this entire subject in a circus; for example was applied an antiterrorist law, they expropriate Mapuche’s lands and always make promise they don’t pretend to fulfill; this action made more strained the relation between the Mapuche and the Chileans.
It is hard to see how your own country is separated in different thoughts and with an impossibility to make an agreement about all the need from each faction. Who have to make the first approach, I think the government, but like I say, they transform this subject in a circus, they don’t pretend to take with seriousness the Mapuche conflict.
Also I don’t approve any of the ways used for the Mapuches, I think that sometimes they are really terrorist. There is no possible explanation that can justify they behavior, more people would die because they risky actions, besides no one will be benefit because they criminal and violent actions.
I Hope someone could mediated in this situation and have a peaceful resolution. Sometimes is difficult to understand the human’s actions

Post 8: My thesis
My thesis is the development of a simulation model of the oxygen transport in soil with 3 to 5 % of Organic Matter content, this wasn’t my original subject, but after a few discussions with my tutor we decided this topic as the most suited thesis to develop.
In O’Higgins, agriculture is one of the most important economics activities, and the fruit production is very sensitivity about environmental stress like unbalanced water content in soil, this unbalanced could causes water deficit in plant or stomatal closure because oxygen deficit to root respiration.
Oxygen is necessary to plant and microorganism respiration, without oxygen the soil is unable to maintain his basics functions. In the same way, begin anaerobics processes and the soil accumulates carbon dioxide, this gas inhibits the roots growth.
To improve the irrigation management is necessary to know the behavior of oxygen and water in soil, bad irrigation management generally cause oxygen deficit and the problems that I mention above.
Therefore the main reason to my thesis is to develop a tool to predict the oxygen concentration in soil, however there isn’t the same level of knowledge of this subject than in other countries, even when the soil that were used has less than 2% of organic matter content, making compulsory to our country have studies in this field of research.
I hope that my thesis became a useful tool to the agronomist, which allows to improving the irrigation management in fruits orchards independent of the soil type.
I forgot to mention that the soil type is highly related with the air capacity of a soil and also with the soil capacity to content water or oxygen, plus uncorrected agricultural management, the oxygen content will be diminish to dangerous level to plants growth.
This study could be just the beginning of other thesis that might find more suitable equations to oxygen diffusion or apply the same methodology to other conditions.

Post 7: Environment
First of all, I think that in this particular topic our society not so concern. Let this subject in different topics.
Pollution, could be one of the more important topics related with the human activities and environment, there is no anthropic actions without consequences thus all the activities we make generate environmental pollution. There is any way maintain our activities and generate zero pollution, in my opinion that is impossible, because we generate direct or indirect pollution and pollution could be chemical or physical, is not only related with waste or gas emissions, for example if we use the water of a river and the return the same amount of water to the river course, but with different temperature our activity generate pollution. Pollution is a very complex concept involves a lot of things related with the environment.
Climate change, in my opinion climate is always changing. The Earth is always in cooler o warmer cycles, we have son proves in the analysis that some researcher did in the Antarctic ice. Don’t you remember that in the 80’s we were talking about a new glaciations, because the temperatures were lower than the average of the 60’s or 70’s, but now we are talking that the Earth is getting warmer and this rise of temperature is related with the carbon dioxide. One of the most affrighting things of this assumption is that could be based in wrong information and in exponential model (the exponential model always rise). I think that we are not the problem…we need put all our effort in the previous topic.
Renewable energies, the renewable energies could the solution to the fossils fuels, one of the most important needs to a develop society is the energy, countries like USA or German consumes between 15 to 50 times the energy that we use in Chile, and they are changing from fossils fuels to renewable energies form the wind or the sun. This could the solution to some of our present problems, but we need to research more.
Carbon and Water footprint, the anthropics activities could be measure with these indexes, both are important and represent different thought the how to see the environment. In my opinion both could be used to make the difference in our actions, but nobody is teaching us the relevance of the environment in our life and how every step we make have a repercussions not only in our life but in the Earth.

Post 5: about the miners
First of all, I need to say that this entire problem is related with our politics, is strange to know that the mining laws are stronger than others, and yet is so basic our technology in the mining industry compared with the profits that this activity generates, I think this is a big paradox; and the recent accident is the probe about this though. Besides, I didn’t saw a real demonstration of goodwill to change this sad reality. In the other hand I hope that our authorities take note on how irregular is the reality of the mining industry, and with that they begin to supervise all the companies, until now, the supervision wasn’t strong enough, so the mining industry didn´t correct their faults related with the workers security.
Maybe someday we will saw a movie relate with this event, like the movie “Alive” (1993) that describe the accident of a Uruguayan rugby team in “Los Andes”. I think that this particular event was much more tragic that the miners accident, because until now no one has died, and they are healthy and safe in the security zone. In fact we’re expecting to save every one without casualties.
Finally, I’m waiting for the safe return of each miner, not only because their family is waiting for them, because all Chile are praying for their lives. This could be one of the most unexpected results in the history of our nation, but happily is a happy ending.

About our Bicentenary
I always believe that September 18th is the most important celebration of our country. Long ago I meet a German and an Argentinian, they tell me that they don't have a celebration like our. For the Argentinian our celebration is like the days that they won the worldcup. They believe that we have a great patriotism.
I think that these days are going to be a big celebration; unfortunately we're not going to have the celebration that we think some years ago, with a lot of monuments or building inaugurations, because in one hand we have to remember that our country had to overcome economical problems, an the other hand we need to remind that our government not always do what they promise.
I think that we have to use these days to share with our family, take some time to think about we expect for the next years and make a goal for us. Also, we have to celebrate our bicentenary and separate sometime to visit historical places, go to places that are related to our independency and get more information about what we’re celebrating. I must say that I never play some Chilean games like “greasy pole” or “catch the pig”, I never been in a “Rodeo”, that is maybe I think that these days are a very good opportunity to try some of them, because they are part of Chilean culture
Finally one of the things that I believe that are wrong: some people don’t know about what we’re celebrating, and they think that September, especially September 18th, is only to fly a kite or a few days of holidays that we can use to go outside of Chile.

POST 3: A place to visit
I want to go to England, Australia, New Zealand, Japan, Italy, French...just a few countries, jejejeje.
I want to know the culture of these countries, for example I want to walk near the Eiffel tower, or get to the Vatican and go to the Sistine Chapel, see the Coliseum in Rome, I think with all these countries I have a lot of tourist places to visit. Also I want to taste the food and beverage from each one, until now I can only taste the food from the restaurant that I visit in Chile, but I think that the taste or flavors will be different if I eat in each country.
If I have to choose one of theme, maybe I will choose New Zealand, one of the reasons is that New Zealand is similar to Chile. Both are in the same hemisphere and share some of same flora (long time ago we were united as one continent, Godwana) and climatic characteristic, so will be nice to know a place similar to my country. The other reason is because they make great advances in subjects related to my career (renewable energies, environmental care or ecological studies) so be there could be a very good experience, in professional terms. I don’t know anything about the food…so could be a risk to me, because I don’t have a strong stomach and I could get sick very easy, but in life we have to take risk to get what we want.
