Extractions: Notícias sobre trigo no Brasil e no mundo. Edições Anteriores Mais de 600 pessoas no Dia de Campo da Embrapa Trigo Durante dois dias estudantes, técnicos e pesquisadores trocaram conhecimentos sobre cereais de inverno na Embrapa Trigo (Passo Fundo, RS), unidade da Empresa Brasileira de Pesquisa Agropecuária, vinculada ao Ministério da Agricultura, Pecuária e Abastecimento. O Dia de Campo Institucional de Inverno, dividido em dois dias, 18 e 19, faz parte da programação na Semana Nacional da Ciência e Tecnologia, instituída pelo Presidente Luis Inácio da Silva em junho deste ano, com o objetivo de mobilizar a população em torno de temas e atividades científicas. No campo, os visitantes ainda puderam tirar dúvidas sobre controle de doenças, fertilidade, erosão no Sistema Plantio Direto (Vertical Mulch), manejo de cultivares e rendimento. Já no saguão do prédio principal da Embrapa Trigo, segue até o dia 22 a mostra de trabalhos voltados a proteção das plantas contra doenças e pragas, com a apresentação de 30 pôsteres nas áreas de fitopatologia e entomologia. "Nestes eventos há interação não somente com a pesquisa, mas também na troca de informações entre os produtores e diferentes grupos de assistência técnica. Deste modo, os participantes dividem alegrias e frustrações, avaliando em conjunto alternativas para crescimento do agronegócio de cereais" , afirma o chefe de comunicação e negócios, Adão Acosta.

Extractions: Herschel Il settecento evolse nella società in cui viviamo, ora giunta alle vette postmoderne. Questo vale anche per la scienza, la musica, l'astronomia che, a partire dal 1780 circa, formulò nuovi formidabili programmi. Uno di questi era la meccanica celeste, finalmente distinta dalla meccanica generale; un altro era l'esplorazione delle profondità cosmiche per mezzo di grandi telescopi. Quest'ultimo si deve soprattutto all'attività di un musicista inglese di origine tedesca, Friedrich Wilhelm (detto William) Herschel, convertito all'astronomia. Nato ad Hannover il 15 novembre 1738, egli non aveva posseduto alcuna nozione di astronomia fino ai trentacinque anni. Il reggimento del padre era stato trasferito dal continente al Kent, dove William diventò organista e con questo mestiere si guadagnava dignitosamente da vivere. Interessatesi dapprima alla matematica, cercò di procurarsi un buon telescopio ma, essendo troppo caro per la sua tasca, cominciò a costruirne di propri. Per otto anni condusse una doppia vita, suonando di giorno e costruendo specchi e montature di sera. Egli voleva dotarsi del massimo potere d'ingrandimento e della massima capacità di scorgere i dettagli deboli, e solo i telescopi riflettori, seguendo lo schema progettato da Newton, potevano essere costruiti in dimensioni tanto grandi da soddisfare questa sua esigenza. Un primo esemplare fu così dotato di un obbiettivo di 48 cm di diametro e 6,3 metri di lunghezza focale.

Extractions: Det var först i och med 1960-talets månutforskning med kulminering i Apollo-projektet som kratrarnas sanna natur framstod entydigt. En bild växte fram av planeter utsatta för ett ständigt bombardemang av projektiler i olika storlekar. De vanligaste, osynliga "dammpartiklar", hade lämnat spår efter sig i form av mikroskopiska kratrar i stenarna som Apolloastronauterna förde med sig hem. En typisk kropp på kollisionskurs i det inre planetsystemet slår ofta ned med en fart på tio eller tjugo kilometer per sekund, vilket gör att det mesta materialet i projektilen förångas med en våldsam explosionskrater som följd. Även "månhaven" är bildade genom nedslag, gigantiska kollisioner som bildat 30-100 mil stora sänkor omgivna av ringberg. Dessa händelser inträffade för ungefär fyra miljarder år sedan. Under några hundratal miljoner år därefter, då månen fortfarande hade ett aktivt inre, fylldes de största nedslagsbäckenen med lavaflöden underifrån och gav upphov till dagens stelnade lavaslätter. Redan med en måttlig kikare kan man dock se enstaka mer färska kratrar även på dessa slätter, vilket visar att bombardemanget inte helt upphört utan att många mil stora kratrar fortfarande bildas.

Extractions: Sweden and St Petersburg by Bengt Jangfeldt, slavist and author Axel Oxenstierna, the great Swedish Chancellor, wrote that it was "beyond all doubt" that in Russia Sweden had "a false and mighty neighbour" who was not to be trusted. In 1615, this enemy was so much âon its kneesâ that the largest and best part of its territory was either in Swedish hands or laid waste. Yet, statesman that he was, Oxenstierna (1583-1654) understood that Russia could one day rise up again. âI readily avow and acknowledgeâ he therefore stressed, âthat nothing could be more convenient, good, secure, necessary even, for our nation and fatherland than peace with Russia â¦â Oxenstierna's words sum up well the relationship between Sweden and Russia, one marked by enmity and rivalry, yet also by an understanding of, in Oxenstierna's own words, "the implications of being neighbours". Russian history has been linked from earliest times with the country which we today know as Sweden. While Norwegian and Danish Vikings expanded westwards, the Swedish campaigns went east. One important route led to Novgorod, or Holmg¥rd. From there it was possible to make ones way south on the River Dnieper to Kiev and thence, via the Black Sea, on to Constantinople, or Miklag¥rd. The Swedish raids on the eastern coast of the Baltic Sea were, however, not entirely dictated by the purse; there was also a missionary zeal on the part of the Swedes to convert the Russian tribes to the true faith. The invasion of Varangians - as the Vikings were called in the east - was followed by a 'crusade' in the 1150s, during which Finland was loosely incorporated with Sweden. At the end of the 13th century Swedish control over Finland was tightened; in 1293 the foundations of the fortress of Viborg were laid, and in 1300 a fortification was built at the estuary of the River Neva. This fortification, Landskrona, could however only be held for a year before being stormed by Russian troops. This was Sweden's first attempt to cut Russia off from the Baltic Sea.

Extractions: af Erling Poulsen Hovedformålet med astronomien er at finde menneskets plads i Kosmos. En væsentlig opgave i den forbindelse er, at finde afstandene til de forskellige astronomiske objekter. Størrelsen af Jorden og afstanden til Månen. De ældste og stadig ofte benyttede metoder bygger på trigonometri (trekantsgeometri). Jordens størrelse blev, efter at græske filosoffer var blevet overbevist om, at Jorden er en kugle, målt af Eratosthenes o. 250 f. Chr. Han konstaterede, at Solens kulminationshøjde i Aleksandria og Syrene i Ægypten var forskellig, og udfra den kendte afstand mellem byerne fandt han ret nøjagtigt Jordens omkreds.

Zanimljivosti O Uranu Da je u pitanju planeta utvrdio je finski matematicar Andres Leksel (AndersLexell, 17401784) nekoliko meseci nakon sto je Hersel uocio objekat na nebu. http://www.astronomija.co.yu/suncsist/planete/Uran/zanimljivosti.htm
Extractions: Prstenovi ... Sadraj AM otkrice Uran je otkrio 13. marta 1781. godine astronom amater Viljam Hersel, pomocu svog teleskopa od 6,2 inca koji je sam konstruisao. Hersel je zapravo samo utvrdio da posmatrani objekat nije zvezda, vec neki drugi objekat, najverovatnije neka kometa. Da je u pitanju planeta utvrdio je finski matematicar Andres Leksel (Anders Lexell, 1740-1784) nekoliko meseci nakon sto je Hersel uocio objekat na nebu. Leksel je izracunao orbitu novog tela, utvrdio da se ono nalazi na rastojanju od 19 a.j. i da je njen orbitalni period izmedju 82 i 83 godine. Izgleda da je nezavisno od Leksela i francuski astronom amater J. de Saron (maja 1781.) utvrdio da se radi o novoj planeti. (Nesto kasnije, 1794. u vreme Francuske revolucije J. de Saron je giljotiniran.) Da bi preciznije utvrdili orbitu Urana astronomi su tragali za nekim eventualno jos starijim podacima o Uranu. I zaista desilo se da je Uran bio osmatran vise puta (tacnije 21 put) pre Hersela. Naravno ti raniji osmatraci nisu znali da je rec o novoj planeti. Najstarije osmatranje Urana pripada Dzonu Flemstidu, 23. decembra 1690. kada je planeta bila u Biku. Osmatranja Urana pre Hersela Flamsteed 1690, 1712. i cetiri puta 1715.
