Kindly advise.

I have extracted dragon fruit flesh by using methanol to get the betalain pigment. Then I want to dissolve this pigment into poly lactic acid solution (PLA dissolve in chloroform). But the pigment not dissolve in the solution. How to dissolve this pigment?

With new high-tech-flight controls on SpaceX crew dragon spacecraft, what is the future of aeroplane displays? Both have complex flight instruments so, what will the future cockpit look like with detailed computer interaction systems for control by pilots? This may include the algorithms directed toward reducing human errors or tackling them.

I had been experimenting with DRAGON version 5 input files. I found that the flux computed by the EDI module not to be normalized. There is a neutron flux level that is computed by the EVO module. Is that the normalizing factor for the EDI module?

Thank you!

I have a problem while calculating molecular descriptors with Dragon 7. My structures are drawn in Avogadro and optimized with Gaussian. After this step, my structures look like the one I uploaded - the aromatic ring in imidazolium is no longer in form of two separate double bonds, the electrons are delocalized instead.

Unfortunatelly, it is not seen in Dragon (I upload the files in .mol2 format). The software warns me that one of C atoms (carbon between nitrogens) has unusual valence, 3 instead of 4 and no aromaticity is detected.

How can I fix this?

I have separated the dataset into training and test set based on IC50 value and I have calculated 2D descriptors from Dragon and Padel software. How to select the particular descriptor for QSAR study? How to interpret QSAR results?

I am deciding whether to buy a license for Dragon (https://chm.kode-solutions.net/products_dragon.php), but I wanted to check if there are any free alternatives that compute most of these features.  I have used Mordred (https://github.com/mordred-descriptor/mordred) and PaDEL, but these only provide a small subset of those available in Dragon, and haven't been as valuable for predictive modeling.  Is there anything free (and preferably open source) that provides anything close to the coverage of Dragon?

Chimera, in genetics, an organism or tissue that contains at least two different sets of DNA, most often originating from the fusion of as many different zygotes (fertilized eggs). The term is derived from the Chimera of Greek mythology, a fire-breathing monster that was part lion, part goat, and part dragon.

Dear All

Last time, I have analyzed dragon fruit peel extract using UHPLC-MSMS. It can be seen for total 13 compounds were detected, only 6 compounds have the activity as antibacterial against S. aureus and E. coli include quinic acid , cinnamic acid (Guzman, 2014), isorhamnetin 3-O-rutinoside (Vagiri et al., 2017), 3,30-di-O-methyl ellagic acid (Nono et al., 2014), apigenin (Sousa et al., 2006) and protocatechuic hexoside conjugate (Stojković et al., 2013). All of these compounds even if have antibacterial activity but cannot be seen through the zone of inhibition test. May I know the reason? Can I said due to possibility is that the bioactive compounds is less diffusible and therefore does not enter the TSA agar?. This could be due to a high molecular weight, chemical reactivity and lack of solubility (Balouiri et al., 2016)

Dear All

what the effect of dragon fruit peel on the water pollution?How danger it is? is it related with BOD,COD,pH

Hi

I want to compute molecular descriptors for anion and cation of ionic liquids. Unfortunately i have old version of dragon software that can not calculates molecular descriptors for ions. May you introduce a free software for calculating 2 and 3D descriptors for ionic liquids?

I've heard a lot about NVivo and Ethnograph. I'm looking into Maxqda also- I prefer a program with tech capabilities such as audio, transcription, apps etc...

Dear Mr/Mrs

I already extracted my dragon fruit peel inside the microwave assisted extraction (MAE) by using water as a solvent. MAE is the close system extraction.But my sample is not fully dissolve into the solvent and still have residue, then i centrifuged to separate solution extraction (supernatant) with residue for further study. May I know is there any issue since my sample is not fully dissolve? I just assume active compounds were extracted into the solvent as powder peel from dragon fruit is really hard to dissolve

Thanks in advance. Your cooperation is highly appreciated.

Dear All

I already done run experiment Optical density versus time for two types of microbe against dragon fruit peel extraction (as file attached). From this graph, Is it correct for its shape/pattern? what else I can explain through this graph? from this graph I can said my solution extraction have very low antibacterial activity. I said that because, I ever run for inhibition zone test, the result is negative (clear zone is not appear)

Dear All

I already analyzed dragon fruit peel using lc-qtrap-esi msms to identify type of phenolic compounds by using full scanning mode. Here I attached file for your perusal. Can I said this phenolic compound is confirm with data base library matching and ion fragment showed fingerprint for each compounds?. Do you agree with me? As i'm not use authentic standard to make confirmation, just depend on libry database. the one things is the name of phenolic compounds from dragon fruit peel are quite strange

What is the time/cost effectiveness of using voice recorders with Dragon speech recognition with NVivo software? Any problems?

Hello, I used E-Dragon to calculate the molecular descriptors, but when I used some SMILES of chemicals, it showed errors, for example, I succeeded to get the molecular descriptor data of O=[Cr](=O)=O, but I couldn't get the data for O=S1(=O)O{-}.[Fe]{2+}.O{-}1 or Cl{-}.[Cd]{2+}.Cl{-}. Does anyone also use E-Dragon or Dragon, do you know why I had this kind of problem? 

As above.

Qualitative structure activity relationship is one of the structure based calculated techniques.
