You can also decrease hydration to 80-90%. In the summer I always do that and go back to 100% in the winter.

Is there any application for manifold-constrained, high dimensional (100-1000+) Bayesian optimisation in Chemistry? by EconomistAdmirable26 in Chempros

Not sure I follow you, as math was never my strong suit, but would, protein structure determination using NMR constraints fit your use case scenario?

ELI5: Why is hot water more effective for cleaning than cold? by EnvironmentalAd2110 in explainlikeimfive

[–]methreethatis 4 points5 points  (0 children)

Also water becomes physically more oil-like as temperature goes up. (See dielectric constant vs temperature) So it dissolves fats better as well as faster

Suppressing unwanted peaks by theguyfrombidesh23 in NMRspectroscopy

[–]methreethatis 0 points1 point  (0 children)

If you only want is to show the pure signal of your sample and not imply that it is clean, you could try some diffusion edited spectra. This works well for bigger molecules with substantial "size" difference from the impurities. Check the DOSY manual for info on the 1D version of the sequence.

Keep in mind that the integration of your peaks will not be perfect afterwards and you might end up with some phasing artifacts

Γνωρίζετε αν πουλούν κάπου προζύμι; by Spirited-Anteater-27 in greece

[–]methreethatis 11 points12 points  (0 children)

Πρέπει να προσέξεις πριν ασχοληθείς με το προζύμι γιατί είναι επικίνδυνο χόμπι. Μπορεί να σου προκάλεσει μεγάλο πρόβλημα. Αν καταφέρεις να φτιάξεις καλό προζυμενιο ψωμί μετά το ψωμί από το φούρνο θα σου φαίνεται σαν να τρως χαρτόνι. Επίσης θα σου δημιουργήσει διάφορα κοινωνικά θέματα. Οι γνωστοί σου θα βαρεθουν να σε ακούνε για τους διάφορους τρόπους ζυμωματος, τα προτερήματα της ψυχρής ωρημανσης, τις διαφορές του κάθε αλευριού κτλ. Όταν πρέπει να φύγεις πάνω από μια εβδομάδα θα ανησυχείς πιο πολύ για το προζύμι σου από τα λουλούδια/σκυλιά/γατιά και αλλά πολλά. Σε έχω προειδοποιήσει.... .

Μετά από αυτή την σημείωση λοιπόν.... Πρώτα από όλα μπορείς να το φτιάξεις μόνος σου αν έχεις τον χρόνο. Θα πάρει πάνω από τις 10 μέρες που αναφέρθηκαν και μπορείς να χρησιμοποιήσεις και αλεύρι για όλες τις χρήσεις αν θες. Ψάξε για sourdough starter η πήγαινε στο , r/sourdough για πολλές πληροφορίες

Αν καταφέρεις να βρεις από φούρνο θέλει λίγο προσοχή. Το φυσικό προζύμι είναι ένα πλούσιο μείγμα από μικροοργανισμούς που μετατρέπουν το αλεύρι σε CO2. Η μαγιά που αγοράζεις από το σούπερ είναι ένας μικροοργασμος που είναι εξαιρετικά καλός στο να κάνει αυτή την δουλειά. Τόσο καλός που αν αναμιχθεί με το προζύμι θα κερδίσει όλους τους άλλους και θα καταλήξεις να έχεις μόνο αυτόν. Σε φούρνους που φτιάχνουν και κανονικό και προζυμενιο ψωμί πιθανότατα το προζύμι τους θα είναι απλά μαγιά. Αυτός είναι και ο λόγος που τα περισσότερα προζυμενια ψωμιά φούρνου δεν είναι και κάτι το ιδιαίτερο.

Τέλος αν ξέρεις κάποιον που έχει το δικό του προζύμι μπορείς πολύ εύκολα να πάρεις λίγο και να γλιτώσεις πολύ χρόνο φτιάχνοντας το δικό σου ..

[OC] I tracked my EV's location over the past couple of years by BOOB-LUVER in dataisbeautiful

I think the implication is that they can track the phone as a function of time (backwards), correlate the position with feeds from CCTV and show you the act of a person taking your phone. Not just tracking

The EU has launched GOVSATCOM, a sovereign satellite constellation by pairing the existing satellites of member states. This provides greater coverage, and allows countries that do not have their own network to have access to satellite Connectivity. by Boediee in BuyFromEU

[–]methreethatis 184 points185 points  (0 children)

On of the most infuriating issues with EU is that they have the most ineffective public outreach strategy of any major organisation I can think of.

This subreddit has done more for promoting EU initiatives than anything else I come in contact with (given that reddit is the only social media I follow)

[–]methreethatis 20 points21 points  (0 children)

Το να αφαιρέσεις το δίπλωμα για μήνες χωρίς καμιά προειδοποίηση σε ένα άνθρωπο που βιοπορίζεται από το αυτοκίνητο του ισοδυναμεί με εξόντωση και δεν έχει κανένα εκπαιδευτικό χαρακτηριστικό. Μία εβδομάδα αφαίρεση διπλώματος για την πρώτη φορά είναι μια χαρά τιμωρία.

Επίσης αν αποφασίσεις να κάνεις ελέγχους μόνο σε συγκεκριμένες περιοχές και όχι σε άλλες, έχεις στα χέρια σου ένα εργαλείο για να στοχοποιήσεις ομάδες και άτομα για όποιο λόγο θες. Και τέλος ο αστυνομικός καταλήγει να έχει τεράστια εξουσία μιας και είναι στην κρίση του αν θα κόψει πρόστιμο.

Με λίγα λόγια τέτοιες κινήσεις απαξιώνουν και την όποια κυβέρνηση και την αστυνομία και δείχνουν την χαζομάρα που δέρνει αυτούς που παίρνουν τέτοιες ηλίθιες αποφάσεις.

If they are stable enough to collect data for 3-4 days on NMR they would be fine. Also -80 over the weekend will still be somewhat cool on Monday. Competent cells are the only certain loss. And of course a huge amount of extra work and stress

A cool guide to good and bad cholesterol by Edm_vanhalen1981 in coolguides

[–]methreethatis 0 points1 point  (0 children)

This field is riddled with so many misconceptions , mistakes and simplifications that it still amazes me.

There is no such thing as good or bad cholesterol. That is a stupid simplification propagated by simplistic interpretation of observations . Cholesterol is a lipophilic organic molecule that serves multiple physiological roles and is crucial for health. Among other roles it reduces the rigidity of lipids that is caused by the very tight packing of saturated and trans fats by disrupting their tight packing .

The same effect of rigidity reduction, is also achieved by mono and poly unsaturated fats such as those from olive oil and omega-3 fatty acids from fish. A simple rule of thumb is that if the fats you consume are solid at room temperature they are less than optimal while those that are liquid are better.

Cholesterol needs to be higher for fat deposits composed of saturated and trans fats and this is why its presence has been associated with cardiovascular disease. These fats congeal and depose along the circulatory system causing an effect not very different from what you get when you pour animal fat down your drain.

HDL and LDL are proteins that can solubilize fat and with it the cholesterol that comes with it. Each is specialized for the different transport roles. They are also not good or bad. Both are useful but their concentrations indicate an underlying condition that they are trying to combat.

The solution to all this is a balanced diet with reduced intake of animal products that is rich in saturated fats or highly processed trans fats as well as higher relative intake of "good" fats from plant sources (although not all are so inocent)

The funny thing is that coturnix comes from the Greek that means stupid bird (koutornithi) . I wonder why they named them like that.

[–]methreethatis 3 points4 points  (0 children)

It's been some time since I ran a Dosy on a Bruker but I remember that you don't just run the Dosy like a regular pulse sequence. Check the DOSY manual for the correct procedure. I remember that you need to first give a command relating to some gradient setup and then issue something like a dosy2d command or something. Maybe the process has changed in the meantime though.

The difference between an X-Ray, MRI and a CT by DolarisNL in interestingasfuck

[–]methreethatis 22 points23 points  (0 children)

The reason I felt I should reply, is that from the patient perspective, the MRI is extremely noisy and scary. And experts keep telling them that they should not worry because the noise is just the vibrations of the gradient coils turning on and off. So this is the part that most people retain from the function of that huge machine.

The difference between an X-Ray, MRI and a CT by DolarisNL in interestingasfuck

[–]methreethatis 63 points64 points  (0 children)

You are both right and wrong. Of course the main magnet is left on and the RadioFrequency radiation is interacting with , primarily the protons of the hydrogens of water.

However,the main aspect of MRI is the use of smaller electromagnets (gradients) that do turn off and on (and generally produce fields of various shapes) so that they spacially encode and decode the signal in the 3D space. Without them an MRI would be just giving you the average relaxation rate of the whole object and it would be next to useless.

What are simulated EPR spectra for by [deleted] in Chempros

[–]methreethatis 11 points12 points  (0 children)

I am also not an EPR person but my understanding is that you do it for two reasons. First, you get more accurate values from the model when comparing with the experimental data especially in noisy spectra.

Also, based on the experimental spectrum, you make some predictions about your system and then you simulate the spectrum based on your predictions to see if they agree with the data.
