One of my bikes without a thumb throttle has this but there is a bit of delay from the long-press required which I don't like compared to the basically instant response of the thumb throttle. It also requires a bit for attention to pre

I really like a low speed throttle, like 3-5mph max is fine. 20mph is too fast and results in ebikes basically designed a motorcycles that cannot be pedaled. The throttle is so nice to have to get started quickly like turning left at a ligh

I assume this doesn't work well otherwise everyone would be doing it.

ITs easy to make X-rays, you just hit a metal target with electrons: https://en.wikipedia.org/wiki/X-ray_tube

You can also generate broad spectrum bremsstrahlung radiation easily, this is widely used for medical X-rays.

Most tents are in fact not very strong in compression unless designed for snow. If you do get a big snow you need to wake up in the night and remove the snow so it doesn't crush the tent.

Mushrooms, mosses, invertebrates and even some plants seem to rely on specific small features that aren't always captured in photos of the thing to identify accurately down to the species level.

This number seems low, so >90% of unsold clothes are worn? Are they all donated? 4-9% of unsold clothes could be defective/damaged or something.

Seems too inexpensive to be made of quartz to transmit the UVC. Typical glass will absorb it, possibly fluorescing a bit in the visible.

That's refraction not scattering though.

There are piezo actuators you could certainly feel but not sure they are made of quartz, maybe PZT.

What is the coffee doing?

by s0rce 8mo ago
I don't really understand how coffee, lacking heavy metals, can effectively give contrast in the electron microscope. I can't access the paper but the available parts didn't seem to explain how this works.

Uranyl acetate for staining is typically depleted and unless you have regulatory issues I don't think the radiation is a big concern, especially when you compare to the very serious toxicity of OsO4 (vapors can react with your eyes and

Norman Borlaug probably comes close. H. Trendley Dean was also impactful on a large scale, while its seemingly less important it helps a lot of people.

Random events are the worst. I was driving through Bend, OR and planned to grab a hotel room but everything was completely booked. Ended up just driving up a random forest road (public land, legal to camp) and sleeping in my tent. Was walk

That would be tricky, I often submitted to multiple high impact journals going down the list until someone accepted it. You try to ballpark where you can go but it can be worth aiming high. Maybe this isn't a problem and there should b

The SDS here may not be sufficient to deformulate as many of the CAS# reported are generic and represent a broad class of compounds. Probably easier to just go run it on a GC.

Yes, this is very common for academic publications, particularly when there could be broad interest. For example, here is the press release from the first publication of my PhD https://web.archive.org/web/20110115053058

I can't imagine this approaches how much is used in agriculture for fertilizer.

While this is just a press release its about the academic paper, which is open access https://www.sciencedirect.com/science/article/pii/S138589472... It doesnt seem like any of the authors are making this com

I checked the lime listed and it seems to be a regular amazon prime item for me (norcal) and not the grocery you described, which we also have.

My experience has been professional engineers are using Solid works. Hobbiests are using a variety of often free software.

Mostly what I was able to read from the papers seemed to work. There were some remaining issues related to detector non-equivalence (I think) that appear to be solved with a temperature stabilized detector or very strongly attenuating the b

I 3D printed some new apertures for an infrared spectrometer at work to reduce some issues that cause artifacts in the data to enable higher accuracy measurements, particularly of high index and reflective samples. Seems to be working well

Probably not visually, you could poke a hole in it and see if there is liquid inside. X-ray imaging may be sufficient to differentiate from conventional cell designs.
