Why Do Tumbleweeds Tumble? | Deep Look - Duration: 3:59.

Thanks to CuriosityStream for supporting PBS Digital Studios.

They're prickly.

Restless.

Rambling.

But if most plants are perfectly content to stay in one place, why does the tumbleweed

hit the open road?

Tumbleweeds start out as tiny seedlings.

They sprout in late winter.

By summer the plant takes on its round shape.

They grow flowers nestled between thorny leaves.

Inside each flower, a fruit with a single seed develops.

This fruit is different than something delicious like cherries.

Lucky for the cherry tree, a bird will carry the fruit away in its belly and disperse its

seeds.

But the tumbleweed takes matters into its own hands.

Come fall, the plant dries out and dies.

The seeds are still in there.

Gusts of wind easily break the dead tumbleweed from its roots.

See where it was attached?

It looks kind of like bones.

A special layer of cells at the base of the plant makes this clean break possible.

Then the skeleton is off, shaking loose tens of thousands of seeds as it goes.

It turns out, some living things spread their seeds better when they're dead.

Like cowboys in a Western, tumbleweeds head out on the open range.

But these icons of the American West actually come from the east, all the way from Ukraine.

They're a common weed in Russia too.

That's why they're called Russian thistle.

They might have hitched a ride here in the eighteen hundreds hidden among flax seeds.

Nowadays, they might amble onto the freeway and make you swerve.

Or get tangled up in your irrigation system.

They could even roll into your neighborhood, pile up and become a fire hazard.

But a green lawn isn't what the tumbleweed is looking for.

It can't compete with plants like grass.

It needs a barren place like this abandoned onion field north of Los Angeles.

With each bounce the tumbleweed sends its seeds flying.

It spreads them out so they all get plenty of sunlight and space.

The coiled-up embryo inside just needs a little water to sprout.

And soon enough, this plant will strike out on its own.

Why do Cylinder Sleeves Drop? | Darton Sleeves [TECH TALK] - Duration: 13:01.

- As we've seen power levels rise with high performance turbo charged

aluminium block engines, the actual strength of the engine block

can become a limiting factor in to how much boost and hence

how much horsepower that engine block can survive with.

It's become a common option with these engines to fit

aftermarket ductile iron sleeves in place of the factory liners

in order to improve strength.

We're here with John from Darton Sleeves to talk about what goes

into that technology.

So John for a start, let's talk about those factory

alloy blocks, what are the weaknesses with those blocks,

and why are the factory alloy blocks a limiting factor

in terms of power and boost?

- The biggest issue with the OEM setups is pretty much all of them,

90% of them come with a stock cast iron sleeve in them.

Issue with that is it's a lower grade material,

they just do it primarily for cost effectiveness.

Their sleeves are only about probably 30, at the max

40000 tensile strength.

Not a lot of strength in that sleeve, and then they're also cast thin

because they're not trying to go bigger bore,

they're pretty much making that block that bore size and that's all

it's gonna do.

So you're limited on how much power that can actually take

because there's also zero ductility with cast iron.

Any type of movement or flex in that cylinder,

since it is only cast iron, it will end up cracking and stuff

and that's gonna be a real big limitation.

Especially when you're trying to take a stock block and increase the power,

add more boost, go much higher compression pistons and stuff,

so adding any more power than what the OEM manufacture intended to,

it will lead to eventual of failure 'cause that cast iron sleeve

it's in the **

- Now another problem with a lot of the alloy blocks that we see are

what's referred to as an open deck design where the sleeves and the cylinders

themselves are really not connected to the outside of the block

so this also presents some other problems even aside from actual

sleeve strength with the sleeves moving around and causing

problems with head gasket failure, is that a sort of a common scenario?

- It is 'cause same issue with the standard aluminium,

they still come with the stock cast iron sleeve,

it's not as much support.

And then added to that, the biggest issue with that,

that goes hand in hand is since there's open deck configuration block,

problem is there's no upper structure or any support.

So what happens under say a high horsepower application,

is you end up getting sleeve walk.

So the cylinders start rocking under a high boost,

the higher horsepower applications.

So as soon as you get any type of movement that cast iron ends up cracking,

and it'll crack all the way out to the aluminium,

ends up blowing head gaskets or cracking the cast iron.

- Even if we're getting to a scenario where we aren't exceeding the strength

of that cast iron sleeve and it's not actually cracking,

with that open deck design, the sleeves will still tend to flex

a little bit at very high boost levels, and ultimately distort slightly,

and that's going to still even affect our ring seal and hence

the power of the engine, even if we aren't cracking the sleeves,

is that correct?

- Correct, there's still your limiting factor of being cast iron.

Having that open deck is just weakening the support.

Like I said any type of movement with that then you're gonna see a failure,

or it's gonna go distort and just completely go out of round anyway,

it's not gonna maintain its figure and stuff throughout the higher

horsepower applications.

- OK so let's talk about Darton's solution to this.

So you've produced a range of ductile iron sleeves.

In particular the product that I want to talk about here is your MID sleeves

that are used to replace the factory cast sleeves on a lot of those

open deck design blocks.

So can you tell us what those ductile iron sleeves are,

and how they work?

- Our MID sleeve, it's made from our proprietary material which is ductile iron

It's based on an ASTM spec for ductile iron but we actually tweaked that

metallurgy to be able to work with a piston ring better

than you know what the standard ductile iron actually is.

So what it is, it's taking say your 30000 tensile strength cast iron

that's in a block and we're replacing it with a much thicker wet sleeve,

and then it's gonna end up 100000 to 130000 tensile strength.

But at the same time still be ductile to where if there say if there is

real high horsepower application, where there may be any distortion

or flex in the bore, it'll flex and not end up cracking,

but it'll still kinda have a memory effect and still go back to its original shape

once the horsepower actually drops back down.

- Now there's two aspects that I wanna talk about there.

So first of all, you've talked about the improved strength of your proprietary

material but on top of the improved strength you're also now,

because you're removing that factory cast iron sleeve plus the alloy

that surrounds it, you've also got a much thicker wall to your

ductile lined sleeve, correct?

- Correct yeah i mean you're looking at say minimum,

you're going from usually stock cast iron, which is only maybe

30000, 40000 thickness in the actual stock and about another 100000

in the ** of the aluminium, we're eliminating all of that and replacing

it with a full wet sleeve design, which will completely take down

the weakest part of that block and replace it with a sleeve

that's gonna be 150000 to 250000 thick.

And a material that's also two to three times stronger,

and then giving you full support at the top so you don't

have a problem with that sleeve walk or the cylinders actually moving

on you under the high horsepower application.

- OK so now just to talk about that ductility because I know you showed

me before, you've got a sleeve out of a top fuel engine

made out of that ductile iron material, and you pressed that almost completely

flat in a press and yet it still hasn't cracked correct?

- Correct yeah I mean I'll show the material.

I'm actually able to take our material, this is a top fuel sleeve,

let's say John Force, Schumacher or ** racing would use,

and we're able to actually take this sleeve and crush it down

probably to roughly about little over an inch

and the sleeve actually its memory effect actually allowed it

to spring back without cracking without any signs of wear

just because of the ductility and strength of the material.

- So obviously if your sleeve crushes to that sort of diameter in operation

you've probably got bigger things to worry about

than your sleeve cracking but it's a good indication or demonstration

of exactly how flexible that material is.

Now the other thing I wanna talk about here is the way those MID sleeves

convert an open deck design block to effectively a closed deck,

so can you tell us how that works?

- Yeah effectively what we're doing is we're eliminating all of that

freestanding wall which is technically the weakest part of the block anyway

so using that kind of limits what you are able to do size wise and power wise.

So we're eliminating that process and then installing our wet sleeve

so then that's allowing you to get full support

at the upper deck of the block so you have zero movement

and then at the same time since the material's so much stronger

than what the stock casting is, and it is thicker,

it also allows you to increase displacement safely and still

be able to push a safe amount of boost through it,

but increase the displacement and adding more rigidity to the block.

- Now I know that a lot of people have trouble with the installation

of sleeves and obviously with your MID sleeves there is a significatnt

amount of machine work required to the block in order

to correctly fit them.

But a common complaint I hear about sleeves in the aftermarket

is that in operation they can drop.

So what causes this dropping and how can that be circumvented

during the installation process?

- Majority of the time it's pure installation error.

The way the sleeves are designed, they have a larger register on them,

it's a solid piece of metal, there's no moving parts,

nothing moves, it maintains its shape, maintains its form once it's

installed properly.

Biggest issue with installation, if the sleeves are gonna move

it's because you're giving it somewhere to go.

A lot of times you have problems where they're decking a block,

and the sleeves aren't completely seated, or they're just not following,

we have specific installation manuals that show you the process

step by step from setting up the block measuring, checking where

your registers gonna be, gives you the tolerances.

If you're not able to hold those tolerances, you're gonna have

problems with installing the sleeve, the sleeve's gonna move

at that point because the tolerances aren't held to spec,

or the machining is just not exact as it could be.

If you're not using like I say a three or four axle CNC,

that would be your minimum basis upon being able to machine

the block properly is it's gonna be a CNC machine.

- So what you're saying there really is this installation,

to do it properly you're getting beyond the capability

of actually doing a good job within your tolerances

using manual equipment?

- Correct, I mean everything's gonna have tolerances to it.

And when you are working with say a half a thou with our stuff,

it's gonna be a half a to a thou tolerances,

a lot of the times without a CNC that's gonna be difficult to maintain,

especially trying to maintain bore centre where that's critical.

Because a lot of blocks have, they're thinner on one side

than the other.

Some of them need an interpolated cut in order to put the sleeves in.

You're not able to do that with a standard boring bar,

or a standard bridge bore without having digitals on it at least,

to be able to maintain that bore centre.

So that three to four axle CNC will give you a lot more accuracy

so that'll eliminate the process of you know taking guess work out,

being able to machine the block properly and get the sleeves in.

'Cause once the sleeves are in, they're seated,

there's a large register on the bottom, heads go onto the top,

everything's held in compression with each other.

So certainly if everything's machined properly,

everything's held in with tolerance, everything's measured exactly

where it should be, there's nowhere for the sleeve to go.

- Now in terms of the installation as well I know there's multiple

schools of thought on whether the sleeves should sit proud

of the deck surface of the block once everything's been machined

ready for assembly,

or whether the sleeves should be flush with the deck.

Is there any recommendations from Darton on that particular aspect?

- It comes down to preference and also application.

Standard street cars where you're just trying to freshen up a block,

you just need to get running again, it's gonna be standard horsepower,

nothing too elaborate, you generally can flat deck the block,

that's gonna be a problem, let the MLS do its job.

A lot of the times when you get to the higher horsepower applications,

some people either prefer to step deck, where they're leaving up

the compression area two to three thou, or running a seal wire in the sleeves.

It comes down to number one, how much power you're planning on running,

is this a street car or is it a drag car, is it a road race a car?

It depends on the power you're making,

how big a bore you're going.

Cause a lot of times when you go to the max bore size on a sleeve,

there's not enough room for a seal wire so you have to step deck instead

to get the better crush on the head gasket.

Or some people with the really high horsepower applications,

they're step decking an running an o ring to get even more

crush on the head gasket.

So it depends on application and certain machinists have

their preferences on which way they're gonna do it.

But a lot of it comes down to, is what the applications gonna be,

street, race, drag race, really high horsepower,

or street strip cars.

- Now the other thing with these MID sleeves or sleeves in general

is if you do have a problem with the engine in operation,

maybe you torch a piston and end up damaging

one particular cylinder, you've got the ability to replace

and individual sleeve?

- Correct, all of our sleeves, our sleeve designs,

they're all replaceable individually or full as a set.

The technology that we based these sleeves upon

was basically the same thing that diesel motors, tractor motors,

ever since they've been in existence that's how they were,

they were generally a ** design.

So what we did is we took that same concept and just

changed the application for it.

So by putting o rings, sealing them along the bottom

of the sleeves, what that essentially does is makes the sleeves completely

replaceable without distorting or bothering the cylinders next to it.

You can take out one cylinder put a new cylinder it,

redeck, rehone and reuse that block over again.

Or if you have a problem, say you go to a max bore size of a kit,

like say on a ** Honda, you go to 90 millimetre,

biggest you can go, you can take all four sleeves out,

put a whole new fresh set it, redeck, rehone,

start it back to 86 or 87 millimetre bore, use that whole block over again.

Since the cylinders are just put in with an o ring,

they don't distort the cylinders next to it because everything's all

individually held in separate from each other.

Why do people love Amazon? - Duration: 5:53.

it's an Amazon lovefest but why is that

what's going on guys welcome back people love Amazon but why is that

Amazon's on a tear right now profits are up the stock is up the customer

sentiment is high it's one of the most trusted companies in America and they

just announced that they have over 100 million Amazon Prime customers worldwide

and people love Amazon so much that last week they actually just announced a $20

a year price hike for Amazon Prime and even though you had some people that

were complaining and not happy about it for the most part it was pretty much

okay how is that possible is the coz waiting for that Jeff Bezos black mirror

robot killer dog series on Netflix wait it would be on Amazon Prime right oh yeah as

amazing as that would be that's not the reason but let's talk about the reasons

why people love Amazon first off first off Amazon is one of the most popular and

even trusted companies in America the verge did a story late last year and it

showed that Amazon ranked extremely high compared to its competition like

Facebook Apple and Google when it came to categories like what kind of impact

is this company having would you recommend them to your friends and

family and do you trust them and universally across the board it was one

of the highest if not the highest ranked company the main reason is that Amazon

concentrates everything on customer value and their whole model is built on

giving you not only the value that you expect but often exceeding that value so

that you feel you're getting more than you paid for you get the free two-day

shipping with a prime subscription but a lot of times you go on there and there's

free one-day shipping or how about when you see all the added benefits you get

from a Prime subscription you get Amazon Prime video you get unlimited free

storage for your photos you get Amazon music for free so those are great

examples of how Amazon tries to go above and beyond to make sure that the

perceived value that you feel for your membership is extremely high and what I

didn't even mention is a consistency in the prime delivery and shipping process

that you get all the time so that's why when Amazon announced last week that

they were gonna up the price of Prime membership you really didn't hear much

about it and being able to increase your price for the same service that people

are already getting and have people not be upset about it is a dream scenario

that most companies can't even comprehend

speaking of other companies Amazon tends to be talked about by other companies in

a very favorable light and a lot of that has to do with the fact that Amazon is

known to be very innovative and obviously they've seen a ton of success

over the years and maybe the admiration isn't so much from the direct

competition but a lot of companies and a lot of different industries try to take

tactics and things and Amazon is made successful and copy that in their own

model and one of the big things Amazon is known for is not being afraid to try

new things and a lot of things they've tried have been smashing successes like

the Kindle Amazon echo or even AWS but not everything has anybody remembered

the Amazon phone but the fact that they're not afraid to try new things

is how they went from being an online bookstore to being a complete

full-fledged tech platform speaking of platform everybody knows about AWS

obviously AWS is wildly successful it's a great profit driver for their business

now but the way that AWS came about is another example of why Amazon is so

respected amongst their peers Amazon's made a habit of trying to solve

problems that they have internally to make their own business run smoother

that they end up being able to sell as a product to other companies because in

the AWS example Amazon was trying to scale up with the rapid growth that they

were seen online and they knew that they were gonna have to build their own cloud

infrastructure because what they needed just wasn't available in the market so

they end up solving internal problems that end up becoming core competencies

for their business that they're able to sell and drive additional revenue

ultimately when it comes to companies being admired by other companies it

comes down to how much success you see and how innovative people perceive you

to be and the Amazon's got both of those

things in spades lastly what about investors Amazon stock continues to be

one of the darlings in the market and the reason for that is because they've

had great returns at the end of the day investors want to make money and Amazon

has been a huge win for people that invested in early and even for people

that have invested in it more recently because the stock continues to go up as

they keep beating expectations every quarter Amazon stock has continued to

soar over the past five to ten years and they're close to being one of the

biggest if not the biggest company in America based on market capitalization

and just FYI if you invested in Amazon just five years ago you would have

already made six times your money and if you take that out even further

than five years it's way way harder investors love good investments that

make the money and that's why they love Amazon so not everything in Amazon's

been perfect they've had some product misses like I

mentioned before and more recently there's the stories in the news with

questions about how they treat their workers but in general Amazon's flying

high right now as it relates to customer opinion the respect of their peers and

wanting to be a company that investors want to be associated with Ursula as a

consumer I love Amazon my Amazon Prime subscription is one of the things that I

valued the most right now that I paid for on a recurring basis I feel like I

get way more value than I pay out of it and the reality is if I'm trying to buy

anything right now I'm looking at Amazon first cuz I know I'm gonna get the value

that I expect and so that's something that's just continues to feed on itself

and why Prime membership is such a valuable thing both for the consumer and

for Amazon as a company so what are your thoughts on Amazon I join it in on the

lovefest or have you had a slightly different experience and you're not

really a fan let me know in the comments below if you like this video hit that

like button down below and if you haven't yet subscribe to join the family

because these are matters of life and check and I'll see y'all next time peace

I don't care I love Amazon take my money Amazon take it because we're waiting for

that Jeff Bezos robot killer dog black mirror darling

robot killer black mare dog is it cuz we're waiting for that Jeff Bezos killer

robot dog black mayor dangit is it cuz we're waiting for that Jeff Bezos robot

killer black no is it cuz we're waiting for that Jeff Bezos robot black Miller

Why Do We Exist? - Duration: 1:26.

I'm Josh from Kitchen Time With Dad, and these are my 6 kids.

Hannah, Sarah, Keturah, Josiah, Leah and Moriah.

(Music)

I started our channel because another dad challenged

me to be intentional about building memories with my kids while they were young.

And since I hear this question all the time, "What's for Dinner?", I decided, why not build

a channel around preparing food and enjoying eating it as a family.

Our family has gone through a number of health issues and that required a lot of dietary

changes.

We've learned how to prepare food, we've learned how to enjoy food, and we want to share that

message with other families who are going through some of those same changes.

Our channel exists so that we can build memories together as a family.

We also want to be able to help other families as they navigate through these dietary changes

they go through.

It's possible to learn to enjoy the food prep again and enjoy eating the food together.

Someday, all of our kids can grow up and leave home with great memories.

Not just great memories, but with good kitchen skills.

That way, they can pass on this legacy to their kids, "Healthy Food for Happy Families!"
