Do you have a source? And are you saying that production of electric cars produces significantly more emissions than petrol?

I know of no super-fast cheap fabrication option. Turn-around for any of the low-cost/two layer fabs is >2 weeks. That’s significant if it’s a hobby and you want to do a project in a weekend, or iterate over a design quickly.

In fact it looks like below 200 mortality increased? And it was worse to have low cholesterol than high in most cases... very odd.

I think they will refund almost automatically (seems like up to 14 days based on another comment). In my experience you need to wait a while (maybe a week?) until the charge registers. After that you can get a refund.

The problem is that app developers often just do both. They charge, but still use adverts. You see this in games in particular. Paying removes /most/ adverts. However it does not remove the “watch an advert to get an extra life” s

Smoking culture in Japan appears to discourage smoking outside. In many places smoking outside is illegal. However some trains, many shopping centers and most restaurants have designated smoking areas. As such you’re somewhat less likely to

“not counting the time spent in the washing/drying machine, I probably spend (at most) an hour a week folding.” This is unclear to me but implies that “folding” includes all laundry activities except “time spent in the washer dryer” (o

The parent comment seemed to suggest that they spent less than an hour was spent per week on all activities not including the clothes were in the washing machine. That’s what I was suggesting was low.

The advice is interesting, but I don’t think warrant telling someone “they’re doing it wrong”. Your extrapolating from your experience with 2 children. Children are difficult and often respond differently to the same techniques. However if

As far as I can tell, based on the statistics I can find, you are somewhat of an outlier: https://www.bls.gov/TUS/CHARTS/HOUSEHOLD.HTM This data doesn’t break the statistics down by family size, but it still comes

While sulfuric or nitric acid is the best way to do this, you can also decap using a box cutter and some patience. I recently did this to figure out if an opamp I bought was fake: http://41j.com/blog/2019/03/v

Maplin mostly stocked poor quality products and massively overcharged. I think charging x10 what a product would cost on eBay is reasonable. But often you’d be charged x100 to x1000 times more for cheap components (resistors etc.). I mostly

This two minute video seems to say very little. That SoftBank is “investing for a future in about 300 years time when we’ll all have chips in everyday objects like streetlights and refrigerators”. And that there’s going to be a global econo

People regularly don’t respond to those emails. For older publications it might be hard to even find the email. In the UK, you can order a photocopy of any journal paper via inter library loans. These often come from the British library, wh

There are two points to note. The first is piracy probably didn’t lead to the failure of the Dreamcast. They didn’t sell many of the consoles... if it was a piracy issue then you’d expect they’d sell many consoles, but few games (the line u

Maybe, but it generally is. In most scientific disciplines I think you’d find it hard to publish simple replication of someone else’s work. You’d need to add some novel aspect, or extend the work slightly. For a healthcare replication study

That’s what the author said, but it seems suspect to me. I’d like to read the rejections and understand if this is just the authors interpretation. But looking at what was done, it doesn’t seem novel. It’s just combining two datasets, and w

Last time I saw them they were being used to print pay slips. Pre-printed slips on continuous feed paper fed into the printers on tracks. The printer then prints the name/amount. Same thing happens with checks. You can get them on cont

In order to publish in a scientific journal the work needs to be novel. Based on this article, the work doesn’t seem novel... I’d like to see the rejections, my guess is they mostly said “this is not novel or unexpected”. To make the work n
