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

 The are mistaken who believe that agriculture and domestic livestock areSojaRude reaching the levels reached without technology, breathing only sector of the economy, there is much there technology.

It was opened on Wednesday (09/03) passage in Campo Grande (MS), the 11th edition of Farming Dynamics – Dinapec, an event that over the years won the trust of farmers and has been considered one of the most important in the industry agricultural.

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.

It was held at Embrapa headquarters with free admission.

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.

The three weeks of COP 21

13 Nov

The three weeks of the opening of the Paris conference, already held the Pre-COP,PreCop21 attended by about 70 countries and chaired by Manuel Pulgar Vidal – Minister of Peru’s environment and president of COP20, the previous conference.
On the agenda were four central themes: the ambition of the agreement, its equity, the concrete actions to be taken before 2020 and the financing to be mobilized after 2020.
The French Minister of Foreign Affairs and International Development, Laurent Fabius, who is the president of cop21, showed the press the main objectives of this preparatory ministerial meeting.
Laurent Fabius said: “” We have had to the pre-COP an important step before Paris, but we are more than ever and mobilize the task that remains is considerable, “summed up in the press conference.
Brazil although the has a bold proposal for contribution in INDC (Intended Nationally Determined Contribution , the acronym in English), which would be 43% (the official website of the event registers 37%) involve illegal deforestation, reforesting 12 million hectares the recovery of 15 million degraded pastures and integration of 5 million hectares of crops, livestock and forests.
But we have in Brazil an extremely dirty matrix (hydroelectric being privatized and expensive nuclear power plants already tried to hang), and goals here are not serious, see the goals of economy and respect for labor achievements

 

As crises climáticas e o homem

11 Aug

O desconhecimento da própria natureza e da natureza que é exterior ao homemTerraCarbonívero é o que propicia a má relação com a técnica, que não é outra coisa senão a outra coisa que as formas de superação da própria natureza e de “dominação” da natureza exterior ao homem.

Primeiro porque a natureza exterior precede ao homem, enquanto a Terra tem bilhões de anos, a vida do homem no planeta data de aproximadamente apenas 350 milhões de anos, a vida primitiva começou antes no período entre 2.5 bilhões de anos e terminou há 554 milhões de anos chamado de Periodo Proterozoico, quando havia oxigênio e as primeiras formas de vida unicelulares, logo em seguida já ocorreu a primeira “crise climática”.

Pode parecer estranho chamar o período em que o oxigênio começa a existir ainda em níveis precários, e isto tornar-se “uma crise de poluição”, mas o oxigênio é um destruidor poderoso de compostos orgânicos, várias bactérias são destruídas por ele e isto obrigou uma “volução” pois os organismos vivos tiveram que desenvolver métodos bioquímicos para reter o oxigênio, um destes métodos foi a respiração aeróbica.

Os períodos entre que se seguem entre 542 milhões e 251 milhões de anos atrás, aproximadamente, são denominados: Neoproterozoico, Proterozoico, e Mesozoica., depois divivdem-se em períodos Cambriano, Ordoviciano, Siluriano, Devoniano, Carbonífero e Permiano, os dois últimos nos interessam.

O Carbonívero (Figura) ocorreu entre 360 a 286 milhões de anos durante o Paleozoicoo, foi o período de formação do ovo amniótico, que permitiu a formação do meio terrestre de determinados tetrápodes, que devido os 4 pés ou patas, permitiu a exploração do meio terrestre.

A segunda grande crise climática acontece no fim do período Permiano, entre 286 a 245 milhões de anos, foi o último período da era paleozoica, quando ocorreu uma grande extinção talvez a maior registrada na história da vida da Terra, dando origem do Triássico, a idade dos dinossauros.

A terceira crise climática foi a chamada era “glacial”, foi depois dela que nasceu o homem nos últimos 30 mil anos da história da Terra, o homem ainda é um bebe e a terra uma senhora.

 

Big networking that is not digital

28 Jul

You can imagine that there is nothing more complex than a computer network, orMaersk even the global network which controls stock and currency exchange rates, plus a plethora of products that go up and down in price every day, but that’s not true, and some would say that we can’t get to build bigger.

There are very complex networks that you have no idea around. One of them was shown on The Verge, which are ships carrying door-containers all over the world, in a global supply chain that transports from tablets to phones, food clothing, toys and souvenirs, etc. And is a country that does not produce any of this, just carries: Maersk of Denmark.

See in the picture (original BBC) a ship Maersk a mega-port in Korea, for this we need a big engineering solution, unprecedented a logistics problem truly create astronomical this network all over the world, delivering products from different sources, validity and natures and do all this work.

The company your in 125 countries, has 25,000 employees, 345 offices and more than 600 active ships, with more than 2 million containers moved per year, and she alone is responsible for 20% of the GDP of Denmark.
