Does someone know if disallowing *.txt in robots.txt can be a problem? I fear a little that robots can’t even access to robots.txt in this case.
When I do a search in google I receive results as expected. When I hover over the search result I can see the correct url. But when I click on it I’m redirected to the homepage. In the search console I find the page not being indexed + google is choosing a different canonical url […]
I have to drive a solenoid with the following schematic: It works great but sometimes the MIC5020 or the input pin of microcontroller fails and can therefore no longer be pulled high, but I can’t quite understand why. VSOL: 48V DC. VSOL_MEAS: measurement pin to see if 48v is present. SOL_SENS: measurement pin to see […]
I would like to install some additional appliances in a room that already has a couple of heavy equipment machines running in it. These are sensitive machines, so instead of having the main circuit breaker trip when there is an overload, is there a device that I could connect to the outlet and then connect […]
I came into possession of an old Electro D-612T variable DC power supply. Based on what I’ve read here and other places it was manufactured in the 1950s, and sold for a whopping $39.95 US at Radio Shack, which today would run around $390 US. These were apparently used quite often at car radio repair […]
Whenever I change the external battery of a Panasonic HC-VXF999 camcorder, the device forgets the time set previously. I’m assuming this happens because the internal battery is broken and I’d like to replace it. I disassembled the camera but I can’t find it. Any idea which component is the battery? EDIT: The manual in the […]
So, here is an example of the correlation plot that seems valid, but I don’t know how to arrive at it: It looks like they have plotted one spectral data against the other, the imp/s axis indicates this. I need to plot the correlation graph between two spectra, the only difference here is that the […]
In the mechanism for Reimer-Tiemann’s reaction, I was told that two alcohol substituents on the same carbon atom are unstable, and this is why salicylaldehyde is formed. In fact, this is not the first time I have come across this. But if this is true, why is it that geminal diols exist? Is it because […]
Please, I got 1 kilogram Zinc Acetate Dihydrate and I want to take my mineral zinc 50-100 mg daily from it. I tried to make a solution with 1 liter boil water in 1 teaspoon (5-6 gram) of that zinc acetate powder. As this powder has about 30% elemental zinc so I think I will […]
How does heat transfer happen between system and surrounding if they are separated by a wall?What happens the molecules from surrounding hit the wall and transfer heat?. If my question is not suitable,I am happy to work on it more.
