I am trying to do a dynamic simulation of ammonia reactor using GEKKO. Unfortunately, my code error says that it can't reach a solution. The equations I am trying to solve are steady-state in terms of species continuity equations but dynamic in terms of heat balance. I used the code shown below to first solve for the steady-state condition, which it does successfully by setting the IMODE = 1. However, when I import the steady-state results and used it to initialise my dynamic-state code, no solution is achieved. I do not understand how my code is not working when solving for the dynamic model since it worked fine for the steady-state model. I have tried IMODE = 4 and 7 but neither of them worked. Does anyone have any idea why my code is not working for the dynamic simulation?

These are the grocery store lists:

I have a list BELGIAN_COAST_list containing hundreds of data frames (df1, df2, ...) of 15 columns X 1000 rows. The last column of each of these data frames is called Chemicals and contains some characters such as Sulfate or Ammonia. But many rows of this column Chemicals are duplicated within each dataframe (due to a technical issue with the measuring device).

I wish to convert the duplicated characters to NULL so that they just appear once in the entire column for each df of my list.

I tried to unlist my BELGIAN_COAST_list and then

I have a table that shows me a chemical concentration value based on temperature, pH and ammonia. The way the I measure these variables, the ammonia level are always one of these six values (on top of the table), so it works as a categorical variable.

I need a way to interpolate on this table, based on these 3 variables. I tried using a combination of INDEX and MATCH, but I was not able to achieve what I wanted. Then I thought of "dividing" the table in intervals to "reduce" one variable and use an IF function to select which interval to interpolate based on the third variable (I was thinking pH or Ammonia), but I can't figure out a way to change intervals dynamically like this.

Can anyone think of an alternative to accomplish what I'm trying to do? If possible I would like to avoid using VBA, but if there is no other way I have no problem using it.

Thank you for the help!

I'm attaching an example of the table below.

I am new to Swift and IOS development, and I am trying to display fetched JSON data onto a text label.

Essentially, my goal is to display only the first object of the following API call result onto a text label (see example further down)

I have the following SQL Server select statement :

My dataset:

The answer for this previous question: extrapolate in R for a time-series data does not work for me due to R versions.

I have a dataframe NEI_othertier1_long that looks similar to like this:

I have a dataframe emissions that looks like this (example):
