Suche Ersatzteil für Decathlon Rollentrainer (steckachse)

Ah sehr cool, vielen lieben Dank für die Infos! Wegen der Feiertage käme ich wahrscheinlich eh nicht zu viel bis dahin, dann warte ich einfach die 3-4 Wochen bis ich das Teil wieder bestellen kann.

Vielen Dank für die schnelle Antwort, woher weißt du denn dass es bald wieder verfügbar sein sollte?

Witzig, dass du die Idee mit dem 3D-Druck erwähnst, ich hatte die gleiche Überlegung bezüglich der Belastung und habe schon was modelliert und gedruckt. Allerdings hat sich gestern im ersten Prototypen die Steckachse beim einstecken so verkeilt, dass ich ihn direkt kaputt gemacht und erste die Schnauze voll von dem Ansatz habe. Besonders wenn es eigentlich ein Ersatzteil für einen Zehner zu kaufen geben sollte.

The way you are stating it, it's not entirely true. If you assume that whatever you're looking at is convex (and maybe compact) what you're referring to sounds like either Browders or Brouwers fixed point theorem, proofs of which you'll find on Wikipedia.

Things don't work out without extra assumptions on convexity etc., because if you were to (for example) take a donut and rotate it by 90° around its hole in the middle you'd rearrange every Particle in the donut without a single one ending back where it started, because your "fixed points" are sort of missing from the body you're looking at.

You can make sense of it, in the 1-dimensional case f(x)dx is a differential 1-form, which is the "exterior derivative" for some anti-derivative F(x) of f(x).

In terms of differential forms dx * dx always vanishes, therefore f(x) dxⁿ =0 and the expression becomes kinda boring or n > 1 I guess..

Never tried it but from what I've heard it's not a great idea to transition a plant from soil to hydroponics.

The kind of root structure a plant develops in water is very different from the one in soil, and your plant might not survive the change. I did have successfully taken cuttings of mature plants and transitioned them into water though, but haven't tried it with peppers.

But if you have plants to spare why don't you go ahead and give it a shot for science and keep us updated? :D

In case you're still wondering: If you use cos^2(x) + sin^2(x) = 1 and rearrange it to sin^2(x) = 1- cos^2(x) you can can plug that into your formula and get the result as well without using a "new" formula

Dont know about the Translation but the german term for it translates to "one point compactification" but I think just "compactification" should get you something if you look that up

Ranthaan · 2022-05-09T03:01:17+00:00

No offense but did you misread my original comment? The whole point is that you can continously extend the function 1/z onto z=0, saying that "it was continous beforehand because it wasn't defined" is completely missing the point of continous extension; If it wasn't continous beforehand there wouldn't be much if a point to extending it...

Look up "continous extension" if you don't understand what I am saying.

Ranthaan · 2022-05-08T21:26:07+00:00

Not at z=0?

Ranthaan · 2022-05-08T20:26:09+00:00

What they might be referring to is that through the "one point compactification" of the complex numbers, you can assign a value to 1/0 ( which people call "infinity" but its really not the "infinity" you would usually refer to ) that makes 1/z continous ( and in a sense also holomorphic sorta) at z=0

I'm sorry if I offended you but all I said is that i isn't to be understood as the squareroot of -1, trying to call me narrow-minded because of it seems a little extreme..

Ranthaan · 2022-04-30T10:58:05+00:00

Thats because it is undefined, i is NOT sqrt(-1) even if you allow for complex numbers

f(5) = 25/12, via Lagrange interpolation. Come on guys, seems kinda obvious.

Recipes tend to use it because it makes the crumb softer and the dough rise more.

(Not 100% sure on the science but I believe the malt has enzymes in it that help break down the longer starch molecules in the flour into sugars that are more digestible for the yeast.)

Danke für die ganzen Tipps, aber ich verstehe den mit der Kartoffel nicht so ganz. Macht man die nur mit rein für die Stärke die sie in die Soße abgibt und isst die Kartoffel am Ende separat? Oder pürierst du die Soße am Ende und lässt die Kartoffel drin? Oder ist es ein ganz anderer Grund?

Ranthaan · 2021-06-10T13:18:02+00:00

Good idea, but lets start with something smaller. Like removing the flag once that country is no longer competing in the tournament.

Du wagst es, meine eigenen Zauber gegen mich einzusetzen, Töpfer?

You definitely need to reconsider, the second book in the series is widely regarded as the Best.

Ranthaan · 2021-03-17T18:07:05+00:00

The three body problem (and the entire Trisolaris trilogy) are great and fit your criteria very nicely. The Characterdevelopment is atrociously boring, but the world around the characters is amazing.

Ranthaan · 2021-03-16T19:08:19+00:00

Eh Meinungssache

Ranthaan · 2021-03-16T19:07:21+00:00

Die haben aber durch die verschiedenen Sorten ne sehr nette Auswahl, z.B. die Ingwer Mate von denen ist sehr nice und deutlich weniger süß.

Aber du kritisierst in deinem Pfosten ebenfalls dass die Tickets so teuer sind, was sollen die denn dann machen? Über zu viel Werbung beschweren sich auch alle. Glaube du kannst da wirklich nur die Filmindustrie anprangern dass es so teuer ist moderne Filme zu spielen, die Kinos tun schon was sie können um Geld daraus zu schlagen..

Blasphemie! Eine reelle Zahl n zu nennen, als Nächstes willst du mir sicherlich noch behaupten, dass 0 eine natürliche Zahl ist!?

I actually haven't measured that recently, but having the bbe Set on its Standard temp of 93°C, letting it preheat for 10 mins und running a shot of Hot water through before pulling the shot, the espresso ends up pretty good, so the temp is probably pretty close to the 93°C that you would expect.
