The MSPs, the so called “eclipsing binary millisecond pulsars” emit a radio signal is distorted or completely disappears, at some particular orbital phases.

Viene data una panoramica del linguaggio Logo, creato da Seymour Papert, che porta allo sviluppo di numerosi altri programmi che ne ereditano le caratteristiche di immediatezza, facilità di comprensione, intuitività e logicità. Tra tutti vengono ripresi Scratch e il suo diretto successore Byob di vengono analizzate struttura e caratteristiche principali, potenzialità e limitazioni con particolare attenzione a Byob e alle novità introdotte rispetto a Scratch.
The 2018 International Champions Cup kicks off on Saturday, with Premier League champions Manchester City facing Borussia Dortmund at Chicago’s Soldier Field in the opening fixture of the preseason tournament which takes place across three continents.A World Cup summer has shifted the focus away from the club game, but with most major leagues now in the final stages of preparations for the new season, what questions do the big clubs need to answer during the ICC?How will Real Madrid shape up in the post Ronaldo, Zidane era?It has been a tumultuous summer at the Bernabeu and the ICC will give us a first glimpse of Real Madrid in the post Cristiano Ronaldo and Zinedine Zidane era.New manager Julen Lopetegui has had a month to prepare for preseason after being sacked by Spain on the eve of the World Cup following Real’s revelation that he had agreed to succeed Zidane as coach of the Champions League winners.But the former Porto coach will have to hit the ground running in games against Manchester United, Juventus and Roma having taken his job in controversial circumstances and then been forced to accept the million sale of Ronaldo to Juventus.In many ways, it is an impossible job for Lopetegui. Zidane left his post in June after guiding Real to three successive Champions League titles and Lopetegui will be deemed a failure if he is unable to make it four in a row in the coming season. But he will have to do it without Ronaldo, the Champions League winning machine whose 15 goal contribution last season was crucial to their third straight title.How will Lopetegui replace Ronaldo’s goals? Will Gareth Bale be given a more regular starting role? Will Real push hard to sign either Neymar or Eden Hazard?Some of Lopetegui’s squad will miss the ICC tour or arrive late due to their World Cup efforts, but Real have big questions to answer and they will need to give clues to some of them during their time in the United States.What will life after Arsene Wenger be like at Arsenal?Unai Emery has made a busy start at Arsenal since being announced as Wenger’s replacement at the Emirates and the new look Gunners will emerge in two ICC clashes against Atletico Madrid and Paris Saint Germain in Singapore.Per Mertesacker, Jack Wilshere and Santi Cazorla have been moved on by Emery, who has added top level experience with the signings of Stephan Lichtsteiner, Bernd Leno, Sokratis Papastathopoulos, Lucas Torreira and Matteo Guendozi.Having finished outside the top four for a second successive campaign last season, Arsenal need to improve and Emery’s first challenge is to get them back into the Champions League.And the encounters with Atletico Madrid Arsenal’s Europa League conquerors last term and PSG (who sacked Emery last season) will ensure that the new boss has high quality opposition to test his team’s early progress.We can expect to see a harder working Arsenal under Emery, with the likes of Lichtsteiner, Papastathopoulos and Torreira injecting some much needed tenacity and winning mentality into the squad.
