It would probably be better to incinerate the waste plastic after a chance at reuse. LDPE bottles wont be releasing much aside from that cut across the top to form the lid if not cut with a hot knife. Any reuse could prevent someone from buying a bag that most likely would be made from polyester that sheds incredible amounts of microplastics. Reduce, Reuse and finally Recycle.
I am much more concerned about all the rubber particles on the roadways from tires, especially with the new Japanese research that suggests the microplastics in clouds are a rubber product.
That sounds super expensive and a logistical nightmare. Imagine a pallet that has 1500 products on it, now those are reboxed, take more space, use more fuel because there will be more trips for each shipment. You also are now tracking probably a dozen boxes instead of a single pallet. There are a dozen boxes to open and inspect before accepting the delivery. You will still have the trucks in the streets too because it cant be easily eliminated if you want to keep auto shops or any light industry where the item exceeds the weight two humans can safely carry.
It would make more sense to me to legislate new commercial buildings must include a loading dock. Require developers to make the commercial buildings have shared loading dock so several small bodegas and stores can all share a dock on their building. This would reduce the amount of the trucks parking in the street with a liftgate or forklift to lower the pallets.
There's also a huge space between 18 wheels and Sprinter. Fun fact: There's even cargo bikes that can carry up to 3 euro pallets (though that's clearly stretching the definition of "bike" to the breaking point) https://pulse.dbschenker.com/de/xxl-lastenfahrrad-europalett...
How is this academia’s moment? People have been publishing bad science since its inception, its why we made tools like peer-review which predate the internet.
also this https://www.universityworldnews.com/post.php?story=202307201... which is bad because the academia is intended to be above this "petty geopolitics". as far as I know academic collaboration didn't quite stop either during the cold war, but I was born after it was over so I don't really know this, might be wrong.
and more than all these, the whole sci-hub debacle is the biggest telltale.
this is not about good or bad science, but about the money incentives.
maybe I'm in a news-bubble, but I also see things about postdocs being a fraud, even PhD's are now a dubious gamble?
and then I add my personal experience doing a masters at a public 3rd world country university, and I just hope it burns to the ground, which is a bad idea to dwell on.
"One of the most internationally cited scientists, Ai Koyanagi, forced to renounce her controversial contract with a Saudi university"
"The psychiatrist, currently employed in Spain at the Sant Joan de Déu Research Institute, declared that her main place of work was King Abdulaziz University, with the aim of elevating the Arab institution in the international rankings"
And is not the only researcher in that gravy train:
"Seven highly cited Spanish researchers [employed by Spain], paid by universities in Saudi Arabia to increase their prestige [posing as fake full-time employees of that Universities]"
The article mentioned how he intentionally crammed together everything to fit on a single unfolded page so they would not need to flip the page over. This article suggests the paper may have been free for Bach though, but I suppose that doesn't account for his time spent writing or rewriting his works. https://www.bach-cantatas.com/Articles/BachPaperSize.pdf
And what about all the candles used to illuminate the parts? Not a single drop of tallow or candle wax or darkening due to the close proximity of a candle has been detected or reported regarding Bach’s original parts. Touching the parts while carrying them or turning pages would tend to leave traces, but these are not in evidence. Eventually these copies of the original parts would be collected and deliberately destroyed by Bach so that they could not be used to reconstruct the cantata.
Another aspect of all old performance materials is the utter absence of rehearsal letters ("A", "B", "C" etc.), measure numbers, little eye-glasses ("watch the first chair here"), bowings, fingerings and all the other things contemporary classical musicians need to put into their parts during rehearsal. It really makes you wonder what a rehearsal in the 18th century could possibly have been like.
And yes, I'm pretty sure Bach saved as much paper as he could. The autograph score to the Christmas Oratorio uses spare staves all over the place. This is not a page-turning consideration. An aria may coexist side-by-side with a chorus for many pages at a time to evidently prevent those 2-3 staves at the bottom of the page from being wasted.
Is self propelled the right wording when you blast a loose propellor with ultrasonic waves? If so I have created a large variety of self propelled robots in my ultrasonic cleaning machine.
Wait until that propeller has controllable pitch and direction, commanded by the on board chip. 20 um x20 um is enough area, in a 2nm process, to accommodate roughly 100,000 transistors. That's about 5x the Apollo guidance computer.
So you would supply bulk ultrasound energy to the organ or area you are treating, and these tiny machines would start to have complex interactions, communicate and locate themselves relative to one another, and coordinate to attack the tumor, deliver the drug, destroy amyloid plaque etc.
20um x 20um is still a bit impractical -- it gets close to the practical limits of wafer dicing, and you need support circuitry. That said, we've made useful payloads in as little as 100um x 100um; here's an example of our (published) work in 200um x 200um:
A 200µm x 200µm x 100µm, 63nW, 2.4GHz Injectable Fully-Monolithic Wireless Bio-Sensing System
That's starting to sound like an RFID device, but with sound instead of radio waves. In this framework I guess the propeller-thing is analogous to a Crookes radiometer.[0] I wonder what would be the Great Seal Bug[1]?
No it's not. It's an external force propelling it. Clickbait article and headline. It's literally a piece of plastic that they move with noise. It's neither self propelling or a robot.
This kind of stuff has also already been done with magnetic fields.
I think this is a fascinating effect seen in almost any hobby. I wonder if there is a word for these sort of sub-hobbies or pre-hobbies. I think you can find it's parallels in cars, aquariums, 3d printers, wood working, etc.
Electronics people use this term for collecting Test Equipment as well. Amusingly, on the EEVBlog forums, one of the largest and most active threads of all is the "Test Equipment Anonymous - Group Therapy Thread" which nominally exists to support those suffering from severe GAS.
Cyclists too, are notorious for frequently pointing out that the correct number of bicycles to own is always n+1, where n is equal to however many you currently own. :-)
Quite a lot of musical instruments are beautiful objects that you could display. While you could display electronic test equipment, even geeks usually don't.
Some people get addicted to the tools of a hobby and not the hobby itself. Sometimes thinking they need the best of the best in order to produce the best.
I still have my Asus ROG g73S from 2010 and boot it up from time to time when I need a windows machine or CD/DVD/blu ray player. It runs windows 10 these days and doesn't have any issues with drivers, I definitely think its closer to apple in terms of both price and longevity. I use a macbook pro as my daily driver now and love the smaller form factor though.
The load cell is amazing BTW. I have one on the creality CR6MAX, prusa has talked about it being sensitive enough to actually do 3d scanning of low-profile objects with it. I doubt they will implement that into the slicer but I don't doubt they can actually print that flat orange perfect first layer with it.
I agree that sharing Gcode should end as well, I understand how they thought that might be a good idea given how daunting prusaslicer is for non-techies but that wasn't a good solution.
Although Corexy is clearly a more rigid form factor I wonder if the input shaping advancements will make that bed slinging i3 seem much faster than we are expecting.
I think the shear strength is the weakness. I break super glued corals off their ceramic plugs for my aquarium and you can almost always get a perfect break by using flush cutters to slide the coral off the plug instead of trying to pry it off or cut it.
I am much more concerned about all the rubber particles on the roadways from tires, especially with the new Japanese research that suggests the microplastics in clouds are a rubber product.
