Volcanoes and Possibilities of Earthquakes

24 Nov

In addition to the civilizing crisis, the forces of nature seem to be more awake than usual, the volcano on the islands of La Palma, in the Canary Islands, a territory of Spain, arouses great interest in the volume of lava that I expect to arrive close in two months and without give signs of truce.

The earthquakes, the number of mouths opened by the volcano (there are now 5), the seriousness of the situation on the island which, despite being confined, has not been carried out any large-volume evacuation, have sparked debates even in the scientific world, the last one is about an earthquake of depth 3.4 or 34 km that happened these days, because the smaller depth would indicate new lava mouths and a greater risk for some abrupt change in the structure of the island which is composed of faults in its interior and large cliffs. depressions towards the sea.

There are several active earthquakes, some are of the Strambolian type, they are volcanoes with explosive eruptions such as emission of essentially effusive lava, and ejection of ash and gases such as sulfur, in incandescent lavas, also launching volcanic rock bombs that are launched from tens to hundreds of meters high, the Cumbre Vieja de La Palma volcano is of this type, in addition to attracting more attention, it is actually more dangerous, due to the terrain where lava can reach, the gases and, in some cases, the deformation of the terrain.

They are linked to the earthquakes that are a result of the Earth’s plate movements, and the biggest concern is not this island located in the Atlantic Ocean, but because it may be a small-scale representation of what can happen on a larger scale in the Pacific Ocean where there is a great circle of fire, name given to a large planetary junction of regions of volcanoes and quite frequent earthquakes and where the possibility of a Big One, a large earthquake from the San Andres fault on the American plate, is speculated.

The real possibility in La Palma is a small tsunami near the island, the consequences would no doubt be devastating, would it be large earthquakes in the circle of fire, or the eruption of large volcanoes like the Yellowstone Volcanic Chair, the Hawaiian Kilauea volcano on which they exist. just sensational speculations.

The consequences in La Palma are still unknown, but the volcano is still active and rather than calming down, these days were one of big explosions and strong earthquakes.

 

 

The Falling Virus as New Concerns

01 Nov

The number of cases in Russia that remained high, new cases emerging in China attributed to the Delta variant, according to data from the country’s own National Health Commission, accused 32 cases in Inner Mongolia, in the north of the country and which has already spread throughout In 11 provinces, cases have been confirmed in Guizhou in the South, Shandong in the East and in Gansu near Inner Mongolia, three cases in Beijing and two in Yinshou, in the Ningxia Hui Autonomous Region.

In Brazil the moving average of deaths continues to fall, now in the range of 260 deaths, with 75% having already taken the first dose, and 55% the necessary doses, it is possible to predict a Christmas and a milder end of the year of the Pandemic in the country, many collective events are already released, games with 100% of the fans and parties and public shows.

The concern now turns to social problems arising from the pandemic, unemployment, impoverishment and rising prices. Even if some social aid does come, it will be insufficient to contain the spread of the crisis.

The closing of downtown offices, the mandatory use of masks and the restrictions imposed on restaurants have transformed landscapes into cities around the world, and are likely to continue in the long term, such as rethinking urban space, what to do with office buildings , closed stores and restaurants in the city centers, smart cities showed paths with a trend, apparently only electronic, now it seems inevitable, in Singapore even policing is done by robots (photo).

The immense empty spaces must be preserved and cared for, without robots the cost is high for a small population, so in many cities they will either remain abandoned centers or they will have to develop more computerized forms of maintenance and policing, in addition to the existing cameras.

It is likely that a reasonable number of people return to the routine of agglomerations in large centers, but there is a tendency to go to smaller cities or leave urban centers and work at home.

 

 

It’s time to change of way

11 Feb

It is not my proposal, but the name of the last book by Edgar Morin (Editor Bertrand do Brasil, 2020), the almost centenary French philosopher shows the lessons of the coronavirus that we resisted in learning, it is also very similar to the name of Peter Sloterdijk’s book : You have to change your life (publisher Relógio d´Água, 2018) this well before the coronavirus.

Before moving on to some of Morin’s lessons, I want to say that we ALL need to change our lives, the planet has run out, words have run out, polarizing politics runs out, and unfortunately sweet words like “fraternity”, “solidarity”, “compassion” ”And so many others seem to be only the will of some that others change, without, however, that each one changes himself first.

The preamble is a historical retrospective from the Spanish flu to May 68 and the current ecological crisis, the lessons from the coronavirus in chapter 1 I comment on at the end.

I begin at the end to affirm that Morin, who also shares values ​​of fraternity, of planetary citizenship, of overcoming inequalities, etc., has in his book a very clear proposal, after demonstrating that the crisis is prior to the coronavirus that only worsened it , on page 4 sentence “… there are two inseparable requirements for political renewal: to leave neoliberalism, to reform the state” (page 46), which will provide the means in chapter 3.

This is actually your second point in the cap. 2 Post-corona challenges, the challenge of the political crisis, of the nine challenges it points to in current crises: the existential challenge, also pointed out in Pope Francis’ Fratelli Tutti Encyclical, the challenges of crises: globalization, democracy, digital, ecological protection, the economic crisis, uncertainties and the danger of a major setback (pages 44 to 53).

The 15 lessons from the coronavirus: about our existence, isolation shows us how those who “did not have access to the superfluous and the frivolous and deserve to reach the stage where we have the superfluous” live (page 23), on the condition recalls the Meadows report, which pointed to the limits of growth, the lesson about the uncertainty of our life, the lesson of our relationship with death, the lesson about our civilization (life turned outward, without inner life, the life of shopping malls and happy hours), the awakening of solidarity, inequality and social isolation, the diversity of situations and the management of the epidemic, the nature of a crisis, the 9 initial lessons.

The lesson about science and medicine, do we understand “that science is not a repertoire of absolute truths (unlike religion” (page 33), the crisis of intelligence, which he wisely divides into “invisible complexities” the way of knowledge “of human realities (growth rate, GDP, opinion polls, etc.” (page 35), point 2. is the ecology of action, it warns that action can “go in the opposite direction to what is expected and return like a boomerang to the head of the one who decided it” (page 35), how many actions and speeches fell in this ditch.

The twelfth lesson is the inefficiency of the state, which, in addition to neoliberal politics, yields “to pressures and interests that paralyze all reforms” (page 38), while polarization deepens.

The thirteenth lesson is national relocation and dependence, and regrets “that the national problem is so poorly formulated and always reduced to the opposition between sovereignty and globalization” (page 39), note the speeches that polarize and do not leave this circle vicious.

The fourteenth lesson is the crisis in Europe, I remember Sloterdijk’s book “If Europe woke up”, and Morin opens the wound: “on the shock of the epidemic, the European Union broke into national fragments” (page 40) .

The fifteenth lesson is the planet in crisis, quotes Prof. Thomas Michiels, biologist and specialists in virus transmission: “There is no doubt that globalization influences epidemics and favors the spread of the virus. When observing the evolution of past epidemics, there are notable examples in which it is noted that epidemics follow railways and human displacements. There is no doubt, the circulation of individuals aggravates the epidemic ”(page 41).

The problem of water and sanitation

19 Nov

Although the planet has plenty of water, the water problem is not negligible and what directly affects the planet, especially the poor and those who live in regions without basic sanitation, is the problem of drinking water, and therein lies the serious problem of contamination by agricultural activities.

Thus, it is necessary, together with the urgent problem of sustainable water management, to think about sustainable development in three dimensions: social, economic and environmental, even those who affirm public policies for this do not accept the reduction of profitable and polluting economic activities.

Studies show that the main causes, about 70%, are due to poor land use in agriculture (pesticides, river silting, intensive monoculture, etc.), followed by industry pollution 20%, domestic use 7% and losses 3% (see the figure above).

Because it was from biology and ecosystems that the ideas of complexity came, this is the sector most sensitive to small attitudes that can and should change the planet in the future, collect polluting waste, do selective collection and even reuse rainwater and using solar energy are attitudes that we can take individually and will be beneficial as a whole, see that complexity can involve simple ideas to be practiced.

The education of the new generations should therefore be the responsibility of everyone, the government, schools and families, small habits inserted in everyday life can transform a huge number of situations in scale, an effect known in complexity as the “butterfly effect”, the flapping of the butterfly wing can influence the climate, and deforestation and neglect of nature has a negative effect on the climate.

Research on planets where there may be life has as its first item the presence of water, and providing drinking water is therefore the first attitude in defense of life.

 

 

Butterflie´s effect and the little things

11 Jun

It seems that to change the world to change everything we must do great things, great projects and in fact not really, small things can make a lot of difference, and the first thing we can change is ourselves, according to Plato’s phrase: “if wants to move the world, the first step will be to move oneself. ”
The butterfly effect, researched and defended by Edward Norton Lorenz, who even created the figure to the side, has double meaning first that he discovered that a butterfly’s wing beat could influence the climate, according to which the graph that created this effect physics heat convection model has the shape of the wings of a butterfly.
Lorenz was simulating global climate models on a computer, and executed another model that by removing some houses after the comma the processing time would be shorter and the result quit faster, in practice it slightly changed the process conditions, and the results were quite divergent.
This means in practice that small actions and interventions in phenomena can along a course influence them deeply, which gives us hope because so little that we do correct, honest and ethical inspiration can in the future dramatically change things, Of course, other people will need to do small things.
A personal experience was to lose a loved one by suicide, made me think a lot wondering what could have happened to that person, after much suffering a psychologist explained to me that not only social and emotional but also genetic, physical and emotional factors could determine the action of that person.
Thinking in the positive sense we can make small gestures, a child asked me to play ball with her, I was hurrying, I stopped and I played for five minutes with her, there the neighbor of a building that saw me with a bag in hand, told me can go now I play with the kid (kids in Portugal).
Also thinking about Brazil, the enormous suffering with all negative social and political events, we must try to see small actions that can be done, to make people aware and to listen when someone is very convinced of their point of view.
I see that Portugal left the crisis winning and recovering the optimism as a people, they did not lose hope, although the crisis has reached many people and still there are reflexes, but it is noticeable the improvement.

Industry and technology: is a Brazilian way out?

28 Apr

Sectors that held the plummet of our economy are maize with a growth of StartUp110% approximately, soybeans 46% and 13.4% cellulose growth recorded in the first quarter 2016 with the economy in decline and the brazilian political crisis still without solution yet.

 

While we see the Brazilian industry is reducing, with major industries out or closed doors, and only the agricultural sector holding on to ask if the high technology has something to say and can be a way to recover the industrial park?

Apparently yes, companies like WEG Santa Catarina, is one of the largest exporters of motor and electronics equipment in the world, and grew 24% last year amid an economic crisis (and political course) because it has a strong standing in exports, almost 55% of its revenue comes from abroad, and employ 31,000 people. Another of a smaller is the Bralyx machines working with confectionery equipment and production masses, has insertion in 50 countries and sales of U$ 12 million, half from abroad, but employs only 150 people.

 

High-tech sectors are promising and Brazil has manpower and a good education system in this regard, a system that helps the startup* in this sector would be important, although the basis of primary and secondary education needs reform.
* Startup – the name given to any innovative company at an early stage.

 

Brazilian Agriculture and Technology

In a 30 hectares area are several stands, and for three days there was the exhibition of technologies; 9, 10 and 11 performances of 15 subjects scripts and 10 practical workshops totaling more than 40 technology.

A prominent technology was soybeans (photo) that can be planted either in the system integrated systems such as crop-livestock (ILP) and crop-livestock-forest (IAFP).

The Dinapec is aimed at farmers, family farmers, businessmen linked to agribusiness, researchers, technicians and professionals of agriculture, teachers and students of rural technical schools and universities throughout Brazil.

Ali was signed technical cooperation agreement between Embrapa and Connan (National Animal Nutrition Co.), also a declaration of interests between the State MS Embrapa and Wri Brazil on State Carbon Neutral Program and was made a nine graduation students Agroescola Program.

After printer, now 3D pen

09 Mar

After the printer, 3D pens It is the launch of WobbleWorks company, creatorEsculturas3D of the first mercado, 3D pen announced the launch of a children’s version of the portable printer called 3Doodler Start a portable printer, reference 3D printers.

The company ensures that it is completely safe, the pen now available for children is a version of the pen “adult” 3D 3Dooler launched in 2013 but had a successful release in 2015.

For this release the controls and operation have been simplified for use by children (actually the recommended minimum age is 8 years), to leave the plastic simply press the single button on the pen to start the output of plastic that is overheated internally.

The market that all copies did not wait long, since there are several alternative models, one is the Lix Pen, a pen developed by a team of designers and engineers with 14mm diameter, the object has the body made of aluminum and concentrates a weight 40 grams, and there are many other eastern origin.

The 3D printers followed the front of this market, their designs are more accurate, faster and generally were made by artists, but this new market that encourages individual creativity, particularly teenagers tend to grow.
