Se inform├│ que las sirenas de ataque a├ęreo comenzaron en #Kharkiv, probablemente debido al misil de crucero Kh-555/Kh-101 lanzado por bombarderos estrat├ęgicos rusos cerca del Mar Caspio.

­čö┤ Todo parecer├şa indicar que luego del ataque a #Crimea de #Ucrania ­čç║­čçŽ (a refiner├şas de petr├│leo ya expresadas con anterioridad) y luego de un ataque a #Kiev luego de dos meses; desde #Mosc├║ tambi├ęn se esper├│ a que Ucrania tenga ya el 98% de los tanques #Leopard y #ChallengerÔÇŽÔÇŽ

Nella giornata di ieri, il Governo ­čçČ­čçž ha riferito che insieme ai carri armati #Challenger verranno inviati in #Ucraina proiettili all'Uranio impoverito (fonteÔÇŽ). 1/5
Questa notizia ├Ę stata commentata oggi dall'├ęlite ­čçĚ­čç║ affermando che ci sarebbero state ripercussioni se questo tipo di proiettili venissero utilizzati (ad esempio, il commento del MoD ­čçĚ­čç║ a riguardo ├Ę in questo video).
Nonostante il DU rimanga fortemente controverso per via 2/5
Della sua teratogenicit├á e della sua tossicit├á (la radioattivit├á in realt├á ├Ę molto pi├╣ bassa di quello che si pensi, gli effetti principali sono dovuti al fatto che il DU ├Ę un metallo pesante), le forze ­čçĚ­čç║ in ­čç║­čçŽ hanno molto probabilmente gi├á utilizzato questo tipo di 3/5

Pues #TalD├şaComoHoy, en 1914, fallec├şa Sir John Murray.

No habr├í un despliegue medi├ítico recordando la efem├ęride, a diferencia de otras #ciencias. Quiz├í la #geolog├şa no vende, una pena, pero la contribuci├│n de #Murray al conocimiento del #planeta es indiscutible.

Va hilo­čĹç!
1- John #Murray es conocido por haber participado en el famoso viaje del #Challenger, el inicio de la #oceanograf├şa moderna.

Pero sobre todo se recuerda el gran trabajo que supuso coordinar la edici├│n final, 50 tomos de pura ciencia entre 1885-1895, de los resultados del viaje.
2- Tambi├ęn particip├│ en otros trabajos de gran importancia para el posterior desarrollo de la #Geolog├şaMarina, como por ejemplo este documento escrito por el propio Murray y Alphonse-Fran├žois Renard, ge├│logo de @GeologyUGent.

They are not invincible, especially for the case of the Abrams and Leopard, that is taken out by "significantly inferior adversaries"...
While it is good news for Ukraine to get these tanks, I (DPA) does not expect the tanks to be significantly different in term of battlefield impact from the over 1000 tanks Ukraine had already fielded since the start of the war.

Neben den bereits zugesagten Systemen #Marder IFV (#Deutschland), M2 #Bradley IFV (#USA) & #AMX-10 RC (#Frankreich), tauchen nun auch anderer Systeme f├╝r m├Âgliche Waffenlieferungen an die #Ukraine auf.

Zum besseren Verst├Ąndnis, hier eine kurze Zusammenstellung:

#Schweden: Selbstfahrende #Archer-Gesch├╝tze. Die 155-mm-Artillerie hat eine Reichweite von 30km und nutzt einen Selbstlader, der es ihr erm├Âglicht, bis zu 6 Granaten in 30 Sekunden auf verschiedenen Flugbahnen abzufeuern.

#Gro├čbritannien: MBT #Challenger2 ab 1986 entwickelt und 1994 erstmals ausgeliefert, ausger├╝stet mit einer 120mm Kanone mit gezogenem Lauf. Vorteil gegen├╝ber Glattrohrwaffen ist die h├Âhere Schussweite von 9.000m gegen├╝ber etwa 4.000m beim #Leopard 2A6.

1/5 "The 2022 WMO/#UNEP #Ozone Assessment contains the most up-to-date understanding of ozone #depletion, reflecting the thinking of hundreds of international scientific experts who contribute to its preparation and review."

2/5 Does anyone with expertise in this area know why charged particles in plasma from #solar #flares, #coronal #mass ejections (#CMEs) and even #localized #thermonuclear #bursts, i.e. #micronovae, were not considered in this report?
3/5 The recommended terms of reference of the 2022 Assessment for the Scientific Assessment Panel (SAP) was supposed to include assessment of information and research related to
solar radiation management and its potential effect on
the stratospheric ozone layer.

Moi qui ne cesse d'appeler aux #nuances et aux raisonnements d├ęcloisonn├ęs (i.e. pas en restant dans son silo / sa chapelle) je suis heureuse ce soir de lire @philippejuvin que j'ai pourtant parfois un peu ├ętrill├ę comme r├ęcemment lors de sa bien tardive r├ęaction sur la place
que les PFL2022 ne font toujours pas pour le #covidlong ().
Si la majorit├ę des malades ont soulign├ę cette prise de paroles, j'ai eu plus de mal ├á battre des mains car d├Ęs que les projets de loi ont ├ęt├ę mis en ligne j'ai ├ętabli que l'ann├ęe ├á venir
serait encore une ann├ęe blanche pour les #patients #covidlongÔÇŽ
Et que j'aurai aim├ę une mobilisation pr├ęcoce pour #challenger le gouvernement plut├┤t qu'une prise de position la veille de l'adoption du PLF ­čśĽ (cf. )

Obiecana #PancernaNitka na temat przysz┼éo┼Ťci czo┼ég├│w w #NATO i UE. Nie b─Ödzie bardzo d┼éugo ani szczeg├│┼éowo, cho─ç postaram si─Ö odes┼éa─ç co bardziej zainteresowanych u┼╝ytkownik├│w do stosownych tekst├│w. Hash o pancerzu polecam r├│wnie┼╝­čśë Startujemy! 1/X
#WarInUkraine #wojnanaukrainie skutkuje licznymi obrazami zniszczonych czo┼ég├│w i in. pojazd├│w panc. Cz─Ö┼Ť─ç komentator├│w na tej podstawie wysnu┼éa wniosek, ┼╝e to (kolejny, min. 6) zmierzch czo┼ég├│w. Faktycznie pole walki na #Ukraina tego NIE potwierdza, podobnie, jak PMT w #NATO. 2/X
Zasadniczo plany te mo┼╝na podzieli─ç na dwie grupy: kr├│tko/┼Ťredniookresowe i d┼éugookresowe. Do pierwszej grupy mo┼╝emy zaliczy─ç modernizacj─Ö posiadanych czo┼ég├│w i zakupy ju┼╝ istniej─ůcych konstrukcji. Stosownych przyk┼éad├│w b─Ödzie sporo, tak w Europie, jak poza ni─ů. 3/X

Et pour finir ce tour d'horizon des #Challenger 2021 du #ChallengeDeLaVeille, voici donc venir l'├ęquipe de #Strasbourg qui fermera la marche des pr├ęsentations demain apr├Ęs-midi...

@IutRSchuman L'an pass├ę, ce sont eux qui nous accueillaient pour la finale du #CDLV2020. Cette ann├ęe, ils ont inaugur├ę cette ├ędition en ├ętant 100% ├á distance...
@IutRSchuman Et visiblement, la finale n'a pas ├ęt├ę une mince affaire tant la concurrence ├ętait rude !

1/ I love learning about the markets. There are some brilliant people IÔÇÖve found on Twitter who have provided great insights (among others):


But this thread is (mostly) about @profplum99

2/ Mike has an encyclopedic knowledge of market history. This interview by @DiMartinoBooth (who I also have a lot of respect for) puts that on clear display.

MikeÔÇÖs explanation of passive investing and its effects on the markets was eye-opening.
3/ According to research conducted by Anadu et al for the Federal Reserve Bank of Boston, passive funds made up 48% of US equity assets under management in March 2020. That number was just 14% in 2005. Meaning 8.6% annualized growth over 15 years.ÔÇŽ

It's #InternationalSaxophoneDay, so here's ESA astronaut @Thom_astro playing sax in space­čĹëÔÇŽ
The first person to play a sax in space was Ron McNair, who played a soprano saxophone on Shuttle Challenger STS-41B in 1984.ÔÇŽ
A track on @jeanmicheljarre's #RendezVous album was meant to include a sax part recorded by McNair on #Challenger in 1986 (would have been 1st music recorded in space). Renamed 'Ron's Piece' in honour of McNair and STS-51L crew #InternationalSaxophoneDay
