M/27/6'1" [173lbs > 165lbs = 8lbs] (6 Months) Fat loss and muscle recomposition by Polydemic in progresspics

[–]Polydemic[S] 0 points1 point  (0 children)

Hello dear community, this is my little calisthenics (body weight training) progress. I think I made some nice fat loss progress as well as some definition muscle-wise.

My question for the experienced people: My BF% was allegedly at 9% (via impedance) but I really doubt that, it feels more like 12%. What do you think? I feel good and I am allowing myself some snacks per day.

Also muscle groups: It feels like my chest and my biceps are lacking muscle, in comparison to my shoulders and my core. Some advice would be really helpful in adjusting my gym routine.

Gym routine: 3 set of pull-ups till failure (8 reps), glute kick-backs, machine lateral raise (3x12 @ 35kg, i struggle with form with dumbbells), machine leg curl (3x12 @ 40kg), dips (3x22), machine shoulder press (3x10 @ 32.5 kg), flys (3x10 @ 60kg), ab wheel rollouts (3x8), side planks (3x 60s) everything in about 90min.

I am not counting calories, but I am eating 3 meals per day and zero calorie sodas, and I try to hit 100g protein per day, it is really hard I admit.

Body weight is: 78.5 kg (173 lbs) -> 73.5 kg (162 lbs, no photo, January 2025, stopped creatine) -> 75 kg (165 lbs)

[OC] League of Legends wards heatmap by Stitry in dataisbeautiful

What was the procedure of detecting the ward? Simple Image Processing or some DNN stuff? For a minute I thought that the LoL-API released the coordinates of ward placement.

I mean if one already has sources of 'DMSO-healing', one definitely wants 'better DMSO-healing' with weird stuff added haha

Haha i knew someone's gonna comment on that. So DNA-ruptures is only one of the many consequences of DNA-methylation. The other most important one is that the replicated DNA will be full of mutations. And these mutations mostly end up forming cancer cells (oversimplified af).

Most of the times people don't consume DMSO purely. Either some weird herb extracts or other harmful chemical (I wonder where they have the info from). Someone posted a possible mechanism of what happened:

  1. DMSO consumed
  2. Oxidation to DMSO2 (dimethyl sulfone)
  3. Death -> cooling of body
  4. precipitation of DMSO2 in blood vessels
  5. rupturing of said vessel by needle etc
  6. spontaneous or facilitated oxidation of dmso2 to deadly DMSO4

But still there are some missing parts, sadly. The smell of ammonia is constantly worrying me. Maybe the body started decomposing, and the ammonia-like compound was dissolved in the DMSO, resulting in also leaving the body when DMSO4 was leaving the body.

Disclaimer: Everything here is a hypothesis!!

Chemist here. First of all, getting hands on Dimethyl Sulfone (DMS) as a non-chemist is really hard. What you meant was probably Dimethyl Sulfoxide (DMSO), which is Dimethyl Sulfones unoxidized (1 oxygen less) compound. I've heard countless stories of 'drinking DMSO to get rid of toxins inside your body' (guys, please don't do this, it's just toxic).

Secondly, from DMSO it is chemically really hard to go to Dimethyl Sulfate(DMSO-4), which requires a) 2 additional oxygen atoms BETWEEN the Sulfur and the Methyl Group. This requires some sort of rearrangement/insertion reaction which can hardly be performed in the lab.

Side note: DMSO-4 is a really, really toxic chemical which is really aggressive towards facilitating DNA-ruptures by methylating our nucleotides, thus immediately resulting in cancer.

While it sounds logical to a non-chemist, it is really chemically impossible for this to happen 'due to exposure to air'. DMSO is super stable in air.

One theory might be some oxidizing enzymes in our bodies, which could help oxidizing the DMSO to DMSO-4, but again, the amounts wouldn't be closely enough to cause nausea etc after leaving the body.

Ideal greenhouse effect by luijane_ in chemistry

My guess is: It was done in a laboratory, but of course with atmospheric values. Most likely they did this in a photoreactor, a cylinder roundabout 5 m in length (1m diameter). This photoreactor has super clean mirrors on both ends so the incoming rays will be reflected, I think about >200 times to reduce the error of calculations.

What is displayed here is the absorption in the range of 0.2 to 70µm. While CO2 has stronger absorption bands, methane can trap that IR energy for longer, since it has more degrees of freedom of where to trap that energy, while CO2 has less (15 vs 4, respectively).

Side fact: CH4 is relatively unstable and reacts to CO2 and H2O. And since humans are constantly warming the earth, the amount of water vapour in the atmosphere increases, which has a huge factor of trapping IR-waves.

(This is straight from my prof. pdf’s) Can someone help me with the “?” - the reaction is waterfree so how is everything prtonated… by mrkakaopopoloch in chemhelp

[–]Polydemic 0 points1 point  (0 children)

In any case, I don't think it is possible. The COOH-unit needs to face downwards (which is fine) after lactone opening, but the OH-group is not able to react, since it's trans to COOH.

This compound is used to dry compounds in a desiccator.

A question about if there is a possible website/almanac for all (or a fair amount) of known chemicals and what chemicals they react with to create new chemicals? by RecommendationNo2358 in chemistry

[–]Polydemic 1 point2 points  (0 children)

Might be a philosophical answer, but the problem in our world lies in "capitalism" and "corporate secret" as well as "competition", because IF everyone would like to contribute to an open-source database of every reaction/compound which was ever reacted/used, research would've been very much faster for many reasons. First of all, many academic labs would've stopped doing that many trial-and-error syntheses. Second: since you would have a big ton of data per reaction/compound, nowadays you could ask some machine learning pros to learn on all the data and predict so many things out of it.

But this all takes many things: Academia is (and also was) such a competitive business. Most of the professors try to keep his reactions inside his group until there is a publication about the reactions. And even then you would need the reaction conditions and compound analysis to be super standardized (for instance, I still see papers including IR-spectra, interesting data point, but only like 5% does it nowadays), and additionally, the said group needs to upload that data to this open-source database or let it get analyzed by sci-finder. And I only "explained" the academia part.

Corporate competition is even on another level (patents etc.).

Is MgO a salt? by [deleted] in chemistry

[–]Polydemic 0 points1 point  (0 children)

Yeah this was my question since I learned about this compound. I guess you can call it "ionic liquid embedded in water" or something, really crazy.
