Maledette zanzare! O come sterminarle con la biotecnologia gene drive
@anarchia
Andrea Crisanti è un nome noto al grande pubblico. DARPA e Fondazione Bill e Melinda Gates lo sono altrettanto per i lettori di questo sito. Tuttavia, se è conosciuto il ruolo di questi https://www.rivoluzioneanarchica.it/maledette-zanzare-o-come-sterminarle-con-la-biotecnologia-gene-drive/

@gdayitsjack @daedalus @ancoghlan hii sorry for the late reply! Besides being genuinely curious about the Australian foss community, I'm also curious about possible OSS job opportunities now or in the future. It's my third winter in Australia and everytime I come here I love it.

"I genitori sono responsabili di tutto ciò che accade sul cellulare dei loro figli."
I bambini crescono in un ambiente digitale che spesso li sopraffà e li mette in pericolo, afferma l'educatore digitale Julian Bühler. Tuttavia, leggi e divieti più severi non risolveranno da soli il problema. Una discussione sulle chat in classe, sulla verifica dell'età online e su cosa può davvero aiutare

I'll probably keep the comic uncolored for now. It's easier and faster. The most important parts are colored (Mitsuru's blue hair and Shakura's red head veins) and I think it gives the comic a certain kind of charm. But I have to admit that I miss the blood stains on Mitsuru's hoodie.

Building And Testing A Turbine Driven Hydro Generator
The theory behind hydropower is very simple: water obeys gravity and imparts the gained kinetic energy onto a turbine, which subsequently drives a generator. The devil here is, of course, in all the details, as [FarmCraft101] on YouTube is in the process of finding out as he adds a small hydro plant to his farm dam. After previously doing all the digging and laying of pipe, in this installment, the goal is to build and test the turbine and generator section so that it can be installed.
The turbine section is 3D-printed and slides onto the metal shaft, which then protrudes from the back where it connects to a 230VAC, three-phase generator. This keeps it quite modular and easy to maintain, which, as it turns out, is a very good idea. After a lot of time spent on the lathe, cutting metal, and tapping threads, the assembled bulk of the system is finally installed for its first test run.
After all that work, the good news is that the 3D-printed turbine seems to work fine and holds up, producing a solid 440 RPM. This put it over the predicted 300 RPM, but that’s where the good news ends. Although the generator produces 28 watts, it’s officially rated for 3 kW at 300 RPM. Obviously, with the small size of this AliExpress-special, the expectation was closer to 750 watts, so that required a bit of investigation. As it turns out, at 300 RPM it only produces 9 watts, so obviously the generator was a dud despite cashing out $230 for it.
Hopefully, all it takes to fix this is to order a new generator to get this hydropower setup up and running. Fortunately, it seems that he’ll be getting his money back from the dud generator, so hopefully in the next video we’ll see the system cranking out something closer to a kilowatt of power.
