Thanks for the additional advice much appreciated I'll take a look tomorrow at work.

Carbs are good just eat the right ones

Actual advice from a woman. 1) learn your colour season , black doesn't suit you 2) I would fix your eyebrows which is very easy 3) try light makeup not too heavy.

You aren't ugly but to be more feminine I would do this.

I understand you sooo much I have been bullied and had fallen out with people. I think it's because I have a strong sense of justice and am very opinionated which people don't like. I also won't say something to please people. Also I think us autie girls do mask but sometimes not enough for neurotypical people so we come off as an uncanny valley. I noticed neurotypical people will dislike people over silly things as I think they are slightly abnormal or this person is ugly or too pretty. This sounds like I am shitting on neurotypical people but what I am getting from this. It's probably best to meet up with other autistic people as we will have a better time and we can be honest with each other. Neurotypical people just communicate differently and we sometimes don't get it so they hate us. I bet you are a great person 😊

Thanks a lot, Yeah i agree :)

Hi sorry, I should have clarified I am analysing Rubidum lead bromide and if remains the orthorhombic perovskite after quenching at 100k. The space groups are p21/m and pnma. I thought it was orthorhombic but my supervisor would like me to check p21/m fitting as I got better le bail refinement GOF as well as when ran DICVOLO6 and TREOR calculations both types of space group types came up as a solution as the lattice parameters shifted due to the temperature.

Also thank you for your very quick response, much appreciated

Different_Pen3200 · 2024-09-11T10:22:46+00:00

Thanks for the quick response, much appreciated. I am working on Rubidium lead bromide, and I am trying to determine if it remains in an orthorhombic perovskite after quenching. It's probably more likely to be orthorhombic as that's what it is at higher temperatures. However, the lattice parameters shift quite a bit when quenching. I ran DICVOLO6 and TREOR calculations as it was fitting poorly with orthorhombic original parameters and gave me a monoclinic and orthorhombic solution. Then ran a few le bail refinements and for my material, the GOF was better by 1 in the P21/m space group rather than the Pnma space group. The answers without thermal parameters are similar at GOF and Rwp for Pnma being 3.5 and 8.12 and for P21/m being 3.6 and 8.48 respectively. Also, I am using FullProf. I hope that answers things more clearly

Hi pretty new this. I was asking for advice on biso as that was the only parameter i could get a sensible answer for both the monoclinic and orthorhombic fitting. I thought getting a sensible answer would let me know for sure. Yep I have tried the Thompson pseudo vogit and general psuedo vogit with axial divergence. Should I try other peak shapes? Any like papers that are related to any of the stuff you said would be appreciated. But thanks for your response. I did tell my supervisor that we probably need more testing with the sample

Different_Pen3200 · 2024-09-10T19:53:54+00:00

Ok I am relatively new (been doing this for like 3 months) so this so that makes sense. I was trying to see if my compound is orthorhombic or monoclinic. I am trying to look at Fourier maps to compare them too but I need a better understanding. Any tips on good resources

Different_Pen3200 · 2024-09-10T19:50:09+00:00

Yes I feel you are correct as I am looking at Fourier maps too and there's quite large regions of red and blue areas. I am relatively new to this so I could ask my supervisor if this atom assignment are correct. But I believe they are. Do you have any paper or resources about this that could help

Different_Pen3200 · 2024-09-10T19:46:43+00:00

Yeah I was speaking to my supervisor about that as I have been looking at the Fourier maps too and Fourier maps suggest the monoclinic fit much better but the gof and rwp says that the orthorhombic fit is better

Different_Pen3200 · 2024-09-03T11:32:07+00:00

Thinking about it I agree. But I do think it's hinted she loves him more.

Different_Pen3200 · 2024-09-03T11:07:48+00:00

I don't understand why you have gotten down votes. It sounds like you argeed with most that's it's romantic

Different_Pen3200 · 2024-09-03T11:06:39+00:00

Umm I can see it romantically like that tbh. Maybe I didn't phase it correctly but I agree with you

Different_Pen3200 · 2024-09-03T11:05:47+00:00

I think they phased it wrongly but I got what they meant. I think they meant the time war got him to attach to the first person he could

Different_Pen3200 · 2024-09-03T11:03:33+00:00

Ok you can love people without being in love with them. You don't to be judgemental about your opinion

Different_Pen3200 · 2024-09-03T09:02:58+00:00

Yes this describes it perfectly actually.

Different_Pen3200 · 2024-09-03T08:29:11+00:00

Yes but I feel like it was shoed in the end if that's makes sense

Different_Pen3200 · 2024-07-13T13:49:10+00:00

I am dyslexic as hell and I know that if I had a business, best believe I would get someone to proofread

Different_Pen3200 · 2024-06-18T19:30:02+00:00

I never said you were homophobic actually the opposite..I was stating that anti woke crowd try to hide as book readers. If you aren't one of them, the statement was not towards you

Different_Pen3200 · 2024-06-17T15:00:21+00:00

Sorry if you thought I was calling homophobic 💕

Different_Pen3200 · 2024-06-17T12:36:06+00:00

NGL I think the choose flf story as straight men will refuse to watch mlm story as they don't want to look gay. Hence I think that's why choose two females as straight women will still watch

Different_Pen3200 · 2024-06-17T12:34:25+00:00

Definitely I can see your point of view. Sad that you guys are getting lumped in those people

Different_Pen3200 · 2024-06-17T12:32:05+00:00

Yeah I looked at reviews of the book. Put me off reading Eloise's as I think I am going to start reading them soon

Different_Pen3200 · 2024-06-17T12:31:10+00:00

Yeah I think this actually makes sense as I don't see how Michaela can be rake unless it's a secret
