In nuclear reactors, why is it that (light) water can act as *either* a moderator or as a neutron absorber depending on the reactor design? Posted: 12 Mar 2020 02:18 PM PDT The way I understand the roll of water in nuclear reactors is this: In reactors that use low-enriched uranium, water acts as both the coolant and the moderator, creating a negative void coefficient. In reactors (namely RBMK reactors) that use natural uranium and light water, water isn't capable enough as a moderator for the core to reach criticality, therefore there needs to be a strong moderator, hence the graphite rods in the RBMK design. The water then acts as the coolant and as a weak neutron absorber, thereby creating a positive void coefficient. Now, I'm confused about the moderation and absorption capabilities of water, because I would think that water is EITHER a net moderator or a net absorber, meaning that while water both moderates and absorbs neutrons, it does one of those better than the other. Specifically in the RBMK design, I'm confused why the increase of voids, therefore a decrease in water density, increases reactivity rather than both the moderating and absorption effects of the water decreasing, therefore resulting in a net zero change from the effects of the water specifically, regardless of the presence of graphite. In other words, even with an increase in voids and a decrease in the neutron absorption, I would expect the water to ALSO decrease in moderation, thereby "balancing out," so to speak. I'm especially confused, because it seems like water has more moderating capability than absorption since it's used as a moderator in many LEU reactors, so I might expect moderation from the water to decrease more than the decrease in absorption, therefore an overall decrease in core reactivity (so I guess that'd be a negative void coefficient in this case?) So, even if it's used as an absorber in the RBMK reactors, the water has to also have a moderating effect as well, albeit much weaker than the graphite, right? As a quick aside, I've also used the neutron scatter/capture chart on this page, and don't know how to compare the values of scattering versus capturing, i.e. whether an element is more likely to scatter than capture or vice versa. submitted by /u/blindMAN219 [link] [comments]

What about tectonic plate rifting? Posted: 12 Mar 2020 08:24 AM PDT So rifting is when plates break apart..but does that mean that the amount of tectonic plates is increasing? submitted by /u/Rekttrex [link] [comments]

Could the anti-psychotic dopamine supersensitivity potentially be used as a more permanent 'treatment' for ADHD? [Neuroscience] Posted: 12 Mar 2020 08:42 AM PDT I discovered this was a thing and knowing that dopaminergic drugs are used for ADHD treatment I was wondering if that information could somehow be used. Is there a way to target the dopamine-pathways normally underactive in people with ADHD with the anti-psychotics for a while, discontinuing and having a permanent higher sensitivity? submitted by /u/PM_ME_INFORMATION [link] [comments]

If somebody has a virus, but has very mild symptoms, is it because they have a weaker form of the virus, the person's specific immune system, or some other reason I'm not thinking of? Posted: 12 Mar 2020 08:55 AM PDT I know that back before vaccines people would say "Oh Jimmy has very mild X, go catch it from him so you'll get a mild case instead of waiting to get a bad case." Is that true at all? submitted by /u/Darkpumpkin211 [link] [comments]

Do tall people have bigger inner organs (heart, lungs, etc)? Posted: 12 Mar 2020 08:45 AM PDT Tall people have generally more space for organs than short people. Does this mean their organs ar bigger, or is there more empty (well, i guess its filled with something?) space between the organs? Does that have any affect to health? What about very short people? Do they have very small organs or are they... Squished? If the organs are a bit bigger in tall people, what would happen if you put a short persons organ in a very tall person? Would it underperform? Could a very tall persons organs be donated to a very short person? Would it fit? submitted by /u/Murksiuke [link] [comments]

If we defined the meter as a static portion of the width of the universe (so as one expanded in size, the other did proportionally), about how much would our meter be expanding in, say, an hour? Posted: 11 Mar 2020 06:33 PM PDT (This may be better suited for a strictly maths-based sub, but I can't tell.) By "width of the universe", I'm not talking about the observable universe, but rather I'm referencing the rate at which space itself seems to be expanding. (Although I would be interested in using the observable universes growth as our constant as well). Perhaps my question doesn't have enough constraints to be answerable, or perhaps it's already a well-observed constant? My apologies if it's easily calculable.

When landing on the Moon, did we approach the surface going the same direction of its spin to reduce the amount of horizontal velocity needed to be scrubbed? Posted: 11 Mar 2020 04:38 PM PDT As I understand, when we launch rockets into orbit, we point them eastward to get a kick in horizontal velocity from the Earth's rotation. This makes me think it would make sense to do the same when landing. I'm thinking that approaching in the direction of the celestial body's spin would mean we have less horizontal velocity to scrub off before landing. If this assumption is correct in a general sense, does it really matter for the Moon since it only rotates once approximately every 27 days? submitted by /u/mikebrady [link] [comments]

How is sweat dealt with in space? Posted: 11 Mar 2020 10:23 AM PDT So I know that there are multiple workout things on the ISS, like the cycle/treadmill.

If a larva were to lose an appendage or other body part, how does this affect pupa development, overall metamorphosis, and the final imaginal stage? Posted: 11 Mar 2020 06:37 AM PDT My understanding is during metamorphosis there is a near-complete breakdown of the larva in to small building blocks. Essentially, the larva matures to the point that it begins releasing enzymes capable of dissolving tissues. As the body is being liquidated (literally), groups of cells begin to organize. From these cells, eyes, wings, and legs begin to form. Eventually this transformation is finalized and the body is completely reassembled. This is the imaginal stage. I wonder what would happen if portions of the initial larva body were missing (e.g. limbs, organs, or bite from a predator)? How would this hinder the development of the pupae? Without some of these building blocks, could metamorphosis be survived? I understand this is a broad question with a lot of considerations. Unfortunately, most articles I've read on metamorphosis assume and fully intact larva. I also apologize in advance if I've gotten any of these terms incorrect. I hope it doesn't distract from my question. Thanks for your insights! -- For context, I'm raising mealworm larva and recording their ability to digest non-biodegradable materials like styrofoam and various polyethylenes. I've noticed many of the larva will choose to cannibalize pupae for their liquids, if I do not offer water every 3-4 days. Once the imaginal stage is complete and darkling beetles appear the beetles will also resort to cannibalism. Unlike mealworms, darkling beetles do not consume styrofoam or polyethylene plastics. Instead, they get all their nutrition from eating larva and pupae. This raises the question as to whether or not a mealworm, after being attacked by a darkling beetle, experiences the pupa stage and overall metamorphosis process differently than a mealworm left otherwise unharmed. submitted by /u/Street_Light_Eyes [link] [comments]

How does the body know if one bacteria is good to keep around, and another (lets say E.coli, as an example) is bad and needs to get rid of it (puking, whatever other countermeasures the body has).

Why have so few people died of COVID-19 in Germany (so far)? Posted: 11 Mar 2020 02:32 AM PDT At the time of writing the mortality rate in Germany is 0.15% (2 out of 1296 confirmed cases) with the rate in Italy about 6% (with a similar age structure) and the worldwide rate around 2% - 3%. Is this because Germany is in an early phase of the epidemic better healthcare (management) outlier because of low sample size some other factor that didn't come to my mind all of the above? tl;dr: Is Germany early, lucky or better? ​ Edit: I was off in the mortality rate for Italy by an order of magnitude, because obviously I can't math. submitted by /u/itengelhardt [link] [comments]

Why is the CMB radiation not only always around us, but ALWAYS with us? Posted: 11 Mar 2020 03:51 AM PDT As far as I understand, the CMB is the result of the recombination, that is when the photons could finally travel freely. If all the photons "escaped" at more or less the same time, why are we constantly "seeing" these photons? Shouldn't they go past us and then be gone to further places in the Universe? Light from the stars is different because stars are constantly producing this light and that's why we can observe it in a constant fashion. However, the moment of recombination is not constantly emitting light because it is that, a moment. So I am very confused. submitted by /u/Atder [link] [comments]

Do satellites maintain the same velocity forever? Posted: 11 Mar 2020 06:18 AM PDT Today in my physics class we talked about the gravitational field and about the elliptical orbit of satellites.

“High energy particles” ejected from a black hole? Posted: 11 Mar 2020 05:50 AM PDT I'm a non-physicist and poor math student trying to slog through Dr Hawking's "A Brief History of Time." He says something in the chapter on black holes that has me confused. He states: As the matter spirals into the black hole, it would make the black hole rotate in the same direction, causing it to develop a magnetic field rather like that of earth. Very high energy particles...could [be] focus[ed]...into jets ejected outward along the axis of rotation of the black hole..." (edits for brevity) I'm not sure how this works - it was my understanding that the gravity of a black hole is so strong that nothing escapes it, including light. If that's the case, how are these "high-energy particles" ejected from the black hole? How do they escape or avoid the attraction of gravity from the BH? submitted by /u/FishFollower74 [link] [comments]

In every article I seem to find, people are saying that magnetic force follows an inverse square law with respect to distance from objects. However when I use paper as a medium to separate, this does not seem to be the case. What's going on here? Posted: 10 Mar 2020 02:55 PM PDT So my setup is a metal baseplate, sheets of paper on top of the baseplate, a magnet, and a bar with a hook on it to connect both a magnet and a newtonmeter. I vary the amount of sheets of paper that seperates the magnet from the baseplate and I record the amount of force needed to pull the magnet off. All of the sheets of paper I used were EXACTLY 0.10 mm, and with the same neodymium magnet each time, (3mm radius, 117mT), I measured the force needed to pull off the magnet for 0, 5, 10, 15, 20, 25, 30, 40, 50, and 60 sheets of paper. What I found was that the expected result that the force needed to pull it off would be proportional to the inverse square, did NOT hold. R^2 for my data was only 0.569, whereas for taking logarithms of the force, the R^2 value was 0.995 instead. This just doesn't really seem to make sense to me with the way that I understand magnetic forces, but this relation is much more akin to finding the half-value thickness of a material for the purposes of attenuating radiation. Similar results were found for when I changed the medium to polymethylacrylate as well, where the log relationship was much stronger. Does anyone have an explanation for this? Have I missed something very trivial? EDIT: downvoted? Wut submitted by /u/i-comment-cat [link] [comments]
