The line that separates day and night is called the terminator. It is also referred to as the "grey line" and the "twilight zone. #terminator #day #night #twilight #earth #natgeospace #neildegrassetyson #nasa #december #billnyethescienceguy #science #geography #space #sun #natgeoexplorer #physics #planetearth #sunset #sunrise #knowledge #facts #winter #christmas

HISTOGRAMA DOSE VOLUME? Venho de RADIOTERAPIA hoje, meu amigo! 😎 Sim, todas essas curvas fazem parte do planejamento radioterápico! Mas, como funciona isso? A radioterapia externa tornou-se universalmente aceita com o advento de máquinas de megavoltagem (cobalto 60 e aceleradores lineares), em virtude da menor dose na pele e homogeneidade da radiação na profundidade. Muito bem, com desenvolvimento tecnológico, o planejamento radioterápico passou a ser conformado. O sistema de planejamento 3D é baseado em um princípio comum: o uso de imagens  de TC ou RM para delimitar a lesão e os órgãos de risco e gerar reconstruções tridimensionais. No planejamento, cada órgão é contornado e delimitado (parece um programa de colorir). A partir da identificação de cada órgão (segunda foto), consegue-se definição anatômica precisa dos volumes alvos e dos tecidos normais adjacentes, permitindo conformação individual dos feixes de radiação aos volumes alvos. Isso é o HISTOGRAMA DOSE VOLUME! Como é possivel ter uma definição volumétrica das estruturas, o plano de tratamento é baseado na habilidade de definir cada subvolume dentro do volume total irradiado e calcular precisamente a dose dada em cada ponto. Isso é importantíssimo para o cálculo da dose final. No gráfico identificamos várias linhas, referentes a cada área daquele tratamento (abaixo ficam os valores de dose). Elas estão dispostas opostas, mostrando que o efeito e distribuição de dose serão diferentes, dependendo da área que estiver sendo analisada. Naturalmente, o volume tumoral (linha vermelha) terá um efeito do que as regiões ao redor saudáveis (linhas inferiores). Este fato possibilita escalonamento da dose de radiação, isto é, altas doses nos volumes alvos e limitação da dose e volume nos tecidos normais adjacentes, dentro dos níveis de tolerância.

This image combines data from five different telescopes: the VLA (radio) in red; Spitzer Space Telescope (infrared) in yellow; Hubble Space Telescope (visible) in green; XMM-Newton (ultraviolet) in blue; and Chandra X-ray Observatory (X-ray) in purple. In the summer of the year 1054 AD, Chinese astronomers saw a new "guest star," that appeared six times brighter than Venus. So bright in fact, it could be seen during the daytime for several months. This "guest star" was forgotten about until 700 years later with the advent of telescopes. Astronomers saw a tentacle-like nebula in the place of the vanished star and called it the Crab Nebula. Today we know it as the expanding gaseous remnant from a star that self-detonated as a supernova, briefly shining as brightly as 400 million suns. The explosion took place 6,500 light-years away. If the blast had instead happened 50 light-years away it would have irradiated Earth, wiping out most life forms. In the late 1960s astronomers discovered the crushed heart of the doomed star, an ultra-dense neutron star that is a dynamo of intense magnetic field and radiation energizing the nebula. Astronomers therefore need to study the Crab Nebula across a broad range of electromagnetic radiation, from X-rays to radio waves. ____________________________________________ Share with friends ________________________________________ Follow for more @icymbols __________________________________________________________ #nasa #space #nebula #blackholes #cern #science #chemistry #physics #maths #research #facts #einstein #astronomy #cern #astrophysics #telescope #cosmos #universe #aerospace #technology #science #nasa #photography #curiousity #astroscience #knowledge #facts #icymbols
Hypergiant Sensory Sciences şirketi kritik yapıları izlemek, takip etmek ve korumak için 5 milyon dolar yatırım aldı. Şirketin amacı ise şu, kritik sayılabilecek, bir petrol şirketi gibi, yerlerin çevresinde ne olup ne bittiğini izleyerek anlayacak. Bölgeye kaç araç girip çıkıyor içinde ne var gibi bilgileri analiz edecek bir sistem üzerinde çalışıyorlar. Şirket olaylara reaktif değil proaktif yaklaşmak istiyor.

#Uraniborg . Astronomer and nobleman #TychoBrahe lived in this castle on the tiny island of Hven for something like 20 years. After a dispute with Danish King Christian the 4th, he was left without financial support and had to look for another patron. He moved to Prague. Uraniborg castle was destroyed. And maybe Tycho’s soul too. He never adjusted to his reduced status as “refugee”.⠀ .⠀ #Astronomy #Denmark #hven #Historymaker #science
These tiny seeds are some of the most powerful tools we have for understanding plants/crops, improving their traits and for protecting them from diseases. When planted, these seeds will produce Arabidopsis thaliana 🌱 🌿 . This is a model plant organism that many scientists use to carry out experiments with. I use them to understand plant bacterial diseases in more detail so we can try to stop them! 🌾☠️🛑 . #PhDLife #phdchat #PhDStudent #PhD #PhDCandidate #stemlife #STEMCHAT #stem #biology #gradschool #postgrad #science #scientistsofinstagram #InstaScience #scicomm #365DaysofScience #bacteria #ResearchLife #Research #myjob #Laboratory #Experiment #scientist #arabidopsis #norwich #uk #england #plant #seeds #plantscience

From @ri_science ”Our fingerprints form in the womb, when the volar pads of our foetal finger tips regress into our growing hands and are patterned by friction. These volar pads stay prominent in some of our mammalian cousins, resulting in toebeans (official science term)” #Amazing #science #nature

"Reflexo Noturno" - Uma das capturas mais difíceis até agora, pois haviam muitas barreiras que estavam impedindo que a imagem saísse com uma boa reflexão da água. Vejam que existe uma cerca na frente, e deixá-la ofuscada diante da luz e do tempo de exposição não foi tarefa fácil. Alguns ajustes ali e outros aqui foi o suficiente pra sair um ótimo resultado. Essa captura foi na Fazenda Experimental Santa Paula - UFVJM Campus Unaí. O clarão branco na foto são as luzes da Cidade, cerca de 12km deste local. #Milkyway #milkywaychaser #milkywayhunter #vialactea #longaexposição #longexposure #nature #naturephotography #moon #landscape #nightscape #starscape #paisagemnoturna #paisagem #natgeo #nasa #science #astrophotography #astrofotografia #astronomia #astronomy
