StumbleUpon. O irmão mais velho da Terra | G1 - Ciência e Saúde - Observatório. Júpiter é o maior planeta do Sistema Solar, todo mundo sabe mas não custa lembrar. Por causa de seu tamanho gigantesco, tem um papel muito importante na formação e evolução do nosso sistema planetário. Até mesmo com implicações no desenvolvimento e longevidade da vida na Terra. Com sua massa de aproximadamente 320 vezes a massa da Terra, ele atrai, desvia e até mesmo engole uma grande quantidade de cometas e asteroides errantes que, se não fosse assim, viria para as partes mais internas do sistema cruzando perigosamente a órbita da Terra. Numa dessas, um cometa a caminho do Sol resolve dar uma passadinha pela Terra e já era. Pergunte aos dinossauros. Além de ser o maior dos planetas no nosso sistema, Júpiter é também o mais velho deles. Uma boa ideia desse tempo foi apresentada por uma equipe internacional do Laboratório Nacional Lawrence Livermore, sediado na Califórnia, EUA.
Essa conclusão veio da análise de meteoritos ferrosos que caíram na Terra. Uau, era um cometa? This awesome periodic table shows the origins of every atom in your body - ScienceAlert. Here's something to think about: the average adult human is made up of 7,000,000,000,000,000,000,000,000,000 (7 octillion) atoms, and most of them are hydrogen - the most common element in the Universe, produced by the Big Bang 13.8 billion years ago. The rest of those atoms were forged by ancient stars merging and exploding billions of years after the formation of the Universe, and a tiny amount can be attributed to cosmic rays - high-energy radiation that mostly originates from somewhere outside the Solar System. As astronomer Carl Sagan once said in an episode of Cosmos, "The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars.
We are made of starstuff. " To give you a better idea of where the ingredients for every living human came from, Jennifer A. Jennifer Johnson To keep things relevant for the human body, Johnson explains that she cut a number of elements from the bottom section. Origin of the Elements in the Solar System | Science Blog from the SDSS. “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff. . ” — Carl Sagan This is an evocative statement. Below is the latest version of an evolving periodic table color-coded by the origin of the elements in the Solar System. My current version of the periodic table, color-coded by the source of the element in the solar system. For this version, I tried to avoid the technical terms and jargon used in the original plot. However, the main point of this blog post is to present the chart and address the following question: Why does your version have different information than the well-known Wikipedia entry?
Wikipedia version, based on the original from Northern Arizona Meteorite Laboratory. Here is a discussion of the some of the differences between the Wikipedia version and mine. Note Backing this statement up with actual evidence may be the basis for a future blog post. Glossary-Nn - Northern Arizona Meteorite Laboratory - Northern Arizona University. Glossary Nn N-Type Semiconductor - Semiconductor that has excess of electrons. For example a semiconductor, such as Si, which has been doped with atoms of a donor element, such as P. The extra valence electrons of the donor atoms provide filled energy states in the band gap, just below the conductionband. Electrons from these “extra” states can easily move into the conduction band and become conduction electrons. Replacing even one in every 106 Si atoms with P can increase the conductivity of the solid by a factor of five million.

International Union of Pure and Applied Chemistry Periodic Table of Elements. The latest release of the Periodic Table (dated 1 Dec 2018) includes the most recent updates released in June 2018 by the IUPAC Commission on Isotopic Abundances and Atomic Weights (CIAAW) (see related News,released 5 June 2018), and specifically for argon, the assignment of an interval for the new standard atomic weight which reflects the common occurrence of variations in the atomic weights of the element in normal terrestrial materials.
An interval in square brackets provides the lower and upper bounds of the standard atomic weight for that element. For users needing an atomic-weight value for an unspecified sample with disregard to the uncertainty, the conventional values are provided. No values are listed for elements which lack isotopes with a characteristic isotopic abundance in natural terrestrial samples.

Definite Integrals | Brilliant Math & Science Wiki. Being one of the fundamental tools of calculus, integrals have a large number of properties coming from the geometry of the coordinate plane, the definition of a functional, and the relationship between integrals and derivatives. Integrals also have an algebraic interpretation that allows for very useful techniques like u-substitution that are necessary for many types of integral evaluation (and in proofs of many properties below!). Sometimes, it is possible to relate the area of one integral to that of others Some properties give information about the limits. The interval is by convention written as . Just as an interval along the real line may be split up, intervals of integration may be split up in accordance with the geometric intuition.
In fact, the previous property allows for to take any value without the risk of ambiguity. Evaluate We have Some properties give information about the integrand. As an operator, the integral is linear. Let Also, let Then Evaluate Using we have. Integral for dummies | Math, Calculus, Integrals. How math is taught in india, incredible.

Brasileira fala em nome da juventude mundial na plenária final da COP-21 | ISA - Instituto Socioambiental. Foi a primeira vez que uma jovem brasileira teve a oportunidade de pronunciar discurso como representante da juventude global numa plenária final de COP. Em seu discurso, Raquel Rosenberg, coordenadora do Engajamundo, deixou claro que a juventude continuará pressionando os governos na luta contra as mudanças do clima Depois de duas semanas de negociação, a Conferência do Clima de Paris (COP 21) aprovou o Acordo de Paris, o primeiro tratado internacional sobre clima de caráter universal, no qual todos os seus signatários possuirão compromissos de redução de emissões a partir de 2020, num esforço concertado para limitar o aquecimento global bem abaixo dos 2 graus Celsius neste século, preferencialmente em 1,5 grau Celsius.
Na plenária final da COP 21, como de costume, organizações observadoras tiveram uma breve oportunidade para se pronunciar oficialmente. Raquel Rosenberg - Engajamundo/YOUNGO Bonn 2015. More drought, floods predicted for the Amazon - Conservation news. Sao Paulo, Brazil’s most populous city, is currently suffering from a severe drought. Meanwhile, over the past year, record floods have hit other parts of Brazil. Though Sao Paulo is hundreds of miles from the rainforest, a study released earlier this year by one of Brazil’s top climate scientists found that deforestation in the Amazon is at least partially to blame for the drought gripping the city and much of the southeastern part of the country. These types of “hydrological extremes” are becoming more frequent in Amazonia.
A drought in 2005 was considered a once-in-100-years event until it happened again — this time worse — in 2010. In addition to deforestation, government officials also blame global warming for the extreme weather. “Climate change has arrived to stay,” said Geraldo Alckmin, the governor of São Paulo State, according to the New York Times. “When it rains, it rains too much, and when there’s drought, it’s way too dry.” Dr. Duffy, P.
