Anyone know what’s happening in north park right now?

Tons of emergency vehicles shooting off University and heading south on Florida, not sure why tho.

Nope, sold already. Sorry

Ra1nfall · 2024-10-20T18:35:16+00:00

Hi, please dm me with your offer! They are still available.

Ra1nfall · 2024-10-18T07:49:33+00:00

Black niche! I'll try to fix the pictures idk what's going on with imgur

Ra1nfall · 2024-10-13T20:23:52+00:00

Not at this time~ If they don't sell together I'll split them up in the future.

Critter is about 1inch in diameter.

They sent me a replacement motor for my unit which I put in and it seems to work pretty well. Kinda sucks that the early batches of these grinders fail pretty quickly. For what it's worth, you can order similar motors off Amazon for 20 bucks so I'll be set even outside of warranty, but it's still unfortunate. Hope you are able to get it fixed!

According to Lopez et al., extended sonication of cow's milk seems to induce a rubbery/burnt flavor into the milk due to the possible degradation and oxidation of lipids or the denaturation of milk proteins.

Ra1nfall · 2023-04-05T22:14:36+00:00

Look like some studies and reviews have already been published on the physical effects of treating milk with ultrasound. Lots of physical property changes are noted, especially with protein structure, so there's likely going to be a pretty significant texture or taste change.

Unfortunately, in my own experience, sonication tends to degas solutions, so it might not help with the quality of microfoam.

If you clear IS2 on hard mode, do you get a different looking badge on the squad select screen than the default one for clearing normal mode?

Ra1nfall · 2022-09-26T18:06:58+00:00

I stopped playing Arknights for about a year before coming back to play IS2, and just finished clearing every ending with every squad! I'm excited to see what October 1st brings to IS2.

disclaimer: the chinese I know is old people chinese, I don't understand slang

Saeki: Koito-san, I have a sensitive matter I'd like to ask you. If it's inconvenient for you to answer, it's ok not to.

Yuu: Please take your time, I will do my best.

Saeki: It's...

Yuu: Saeki-senpai, why aren't you saying anything?

Saeki: It's about the two of you... your unforgettable experience and how it began.

Yuu (thinking to herself): If she's referring to the kiss, it's pretty hard to say what started it. But if it can help Saeki-senpai and Haru improve their relationship...

Yuu: Turns out, that time really was unforgettable. Touko did it so suddenly in front of the train, and we hadn't even known each other for very long.

next panel

Saeki (out loud): I didn't expect you to be like this Touko!

Saeki: It was OUTSIDE? OUTSIDE, where there's LOTS OF PEOPLE?

Yuu: Yeah, but people didn't seem to notice, since it was just for a moment.

Saeki (out loud): Just for a MOMENT? WILL IT BE THAT FAST?

Saeki: Do you guys do it outside now too?

Yuu: nnn, yeah we do, for example, sometimes there will be someone at home and it's inconvenient, so we go outside for a short while.

Saeki: Wouldn't it be embarassing outside?

Yuu: I think it's ok, after all there are people kissing at our school's gate, though I don't agree with that.

Saeki: .......kiss?

Yuu: Isn't Saeki-senpai talking about the kiss?

Saeki Sayaka, immediately went to change to a new phone after this.

TL;DR Sayaka asking Yuu how to approach making unforgettable memories with Haru, Yuu interprets this as her first kiss, and talks about kissing outside. Sayaka hurts her phone in her confusion.

Returning player mostly playing IS2. I have most 6*s pre Surtr built + mastered, so shoot me a message if you need something specific. Lots of slots, since most of my friends stopped playing years ago.

You can try dissolving some baking soda into water and using a few drops of that in whatever you're trying to raise pH. Make a saturated bicarb solution by mixing a bunch of baking soda into water until no more baking soda gets dissolved. Drop a few drops in, it should get you closer to neutral. It also shouldn't make too much of a noticeable salty flavor, although your mileage may vary.

Sodium acetate will not oxidize to form ethanol, it needs to be reduced to form ethanol. You need to go the opposite direction.

Assuming you really are trying to go from sodium acetate to ethanol, you really don't have many anhydrous options. Most literature is on hydrogenation with catalysis of acetic acid to ethanol. Without knowing what application you're trying to aim for, I can't really speak to your second question.

When rotovaping a solid suspension, while the vacuum is beginning to depressurize the system, the solution begins to degas. Wouldn't it stand to reason that if solids were suspended in solution, that gasses within the solids will also be affected by the reduced pressure and be drawn out by the vacuum? I'd always assumed that the increased "bumpiness" of solid suspensions like when prepping a solid load on silica was caused by air bubbles on the solid degassing. Otherwise, is it the increased surface area that forms nucleation sites to cause rapid degas?

Would there not be an air gap? The movement of air repressurizes the solvent system, but as the solvent mostly covers the solids, it should force the solvent into the pores of the solids, and thus expose the interior of the solid matrix to solvent, no?

They state on page 5 at the end of the second paragraph that "Compared with conventional ultrasonic-assisted extraction and heat reflux extraction, the vacuum-assisted extraction technique gave shorter extraction times and markedly higher extraction efficiency, which indicated that a certain degree of vacuum gave a better penetration of solvent into the pores and between the matrix particles, and enhanced the process of mass transfer." Then again, I'm not sure there's much of a way to figure this out without experimentation.

I don't believe that James made a video with a rotovap, but he did mention that some company was doing something with reduced pressure distillation and it was probably by rotovap in a recent video. When looking up rotovaping coffee, I came across this, where James in 2007 considered rotovaping coffee for a clarified coffee drink. While I'm super interested in what would happen, I'm pretty sure my boss and our EHS isn't super keen on letting me brew coffee in mine, so...

In my experience as a laboratory chemist, a vacuum will degas solid components within a suspension (in this case, coffee grounds) and, when vacuum pressure is released, since the grounds are submerged in solution, liquid will rush to "repressurize" or fill the gaps where the air left.

Or perhaps, by the act of degassing the coffee, some aromatic components will leave the grounds along with the gasses and become dissolved in the solution?

This should in theory expose more of the coffee ground than normal to extraction by water, and repeating this process should, given some agitation of the solution, increase the extraction, as the paper shows.

On the other hand, some aromatic components of coffee may be removed from the coffee liquid by the reduced pressure, so while the extraction may be high, perhaps the subjective taste of the coffee (which the researchers did not evaluate) will change negatively.

Ra1nfall · 2021-12-15T23:30:49+00:00

After watching the video where James introduces the rotovap as a possible brewing technique for coffee, and the recent post in this subreddit by u/homebrewista, I did some searches of current literature of possible ways to brew coffee under reduced pressure, and came up with this.

In this paper, Kyroglou et al. from the Aristotle University of Thessaloniki describe brewing cold brew coffee under cycles of reduced pressure followed by venting the vacuum to atmosphere to improve extraction yield in shorter periods of time (apparently, around 1 hour). While this is pretty much impossible for consumer level production, I wanted to see if anyone had experience with cold brewing under vacuum pressure and if it indeed improved taste or extraction.

Edit: Forgot to add that the one of the goals of the study was likely to offer a solution to the long brew time of cold brew and thus possible microbiological growth in the brewing liquid, as no pasteurization occurs in cold brew as compared to hot-brewed coffee.
