Ask Electronics@discuss.tchncs.de•Can I use a steel sponge as a soldering sponge? (SOLVED -> better not)English
2·21 days agoa spark is typically hotter than 800°C while soldering above 400°C just isnt something you see for electronics. (brazing is another matter though)

13·22 days agoit is not dangerous in any way since it is just metal and metal oxides that do not mobilize at the temps you use for soldering. it is not recommended because the protective layer on most modern soldering irons is made from iron (not steel) and iron is softer than steel.

That is standard for all rewirable connectors though.

there are still countries where hunting with lead shot is common. and there are gun nuts who think this is not a big deal, because only owls and other birds of prey die from it.

I remember reading about metamorphosis in lepidoptera (“butterflies”) and how the imago (“adult”) is able to react to stimuli it learned about when it was still a larvae. that might sound kind of boring in itself until you learn that during the pupal stage the nervous system of lepidoptera exists in a very “fluid” state. that knocked my idea of understanding what memory is almost all the way down to zero again.

Bready@lemmy.world•The fungus that makes bread better for youEnglish
1·5 months agoThe article is open access: https://nph.onlinelibrary.wiley.com/doi/10.1002/ppp3.70051
Summary
- Bread wheat, the world’s second major food crop, is crucial for global nutrition. Enhancing Zn and Fe bioavailability in wheat grain can combat human nutritional deficiencies. There is demonstrated potential for AM fungi to support these goals through increased uptake of Zn and Fe into wheat. However, AM fungi can also increase P uptake, leading to higher phytic acid levels in the grain, which can hinder Zn and Fe absorption in the digestive system.
- Eight Australian wheat varieties were grown with or without AM fungi (Rhizophagus irregularis) and two soil P treatments (addition of 0 or 25 mg P kg−1 soil) in a controlled growth environment. At maturity, plants were harvested and analysed for grain biomass, nutrition, phytate and 2D spatial elemental distribution within grain using X-ray Fluorescence Microscopy.
- Our results indicated that the AM-colonised plants had greater grain biomass and accumulated greater amounts of P and Zn in whole grain and Zn in the aleurone layer, but not Fe. Increased P did not raise phytate levels, leading to overall higher Zn and Fe bioavailability in AM-inoculated plants compared to non-inoculated controls.
- AM fungal inoculation could be a promising strategy for producing wheat grain with higher micronutrient bioavailability for human nutrition, without compromising agronomic practices (P fertiliser application) or yield targets.

Home Improvement@lemmy.world•Advice for fire pit constructionEnglish
1·6 months agomarble is less resistant to heat but might work if it’s not directly in contact with the ambers and a little away from the fire. Chemically it is CaCO3 and if you heat it enough it will start to decompose to CaO and CO2 and crumble. It is a similar process to what you would see in a cement kiln :); not exactly stable but also not dangerous if it happens outside.
