An answer to your question may depend on your (La)TeX distribution.
(personally, I do my package installations by calling tlmgr---the (La)TeX package manager for my distri, TeXlive)

For starters, you could try to use the {sidewaysfigure} environment provided by the rotating package...or what is your problem, exactly?

@comandos: even if the tabularx environment would allow stuff like that in its first argument (which it doesn't, it expects a length there), \MakeUppercase expects an argument, Since there are no braces, it would grab the \bfseries command, biut since there's no text... The easiest way would be to u...

If I understand you right, s.th. like \documentclass{article} \usepackage{circuitikz} \usetikzlibrary{arrows.meta} \usepackage{siunitx} \begin{document} \begin{circuitikz}[american currents,american voltages,line width=0.25mm] \draw (2,4) to [R, l2^=$R$ and \SI{1}{\kilo\ohm},*-] (2,2)...

perhaps it helps if you change \bibliography{Library.bib} to \bibliography{Library} Anyway, your Library.bib.bib seems to be in html format (and not in .bib format) Since I'm not at the university of Auckland, I didn't attempt to open the file...curiously, there it's called `Library.bib' and not `Li...

I would refrain from spaces in filenames. Additionally, I'd check for the presence of a .nlo file first, before trying to invoke \write18 on it. And then there's no output of \printnomenclature, as long as there's no text at all... \documentclass[review]{elsarticle} \IfFileExists{\jobname.nlo}{% \im...

Hi Joseph, Actually, I realized that the source I take the citations from automatically puts the backslash there and it can not be configured to leave it out, so I have to manually remove them. There are numerous journals I cite so making a \newcommand for all of them would be much more work. well, ...

I'm having an "undefined control sequence" problem when trying to compile the tex source. LaTeX Warning: Citation `article2019' on page 2 undefined on input line 26. (./texfile.bbl [2] ! Undefined control sequence. l.6 \newblock {\em \apj }, 42:44, July 2018. I discovered that if I remove...

Sorry about that.
You're quite right, `set/unset' aren't the words I should've used...
Perhaps I should've said `\parskip is usually set to zero (disregarding any shrinkable/expandable glue)'

I'm confused: we subtract some vertical space explicitly before, never give it back explicitly, but still the result is as if we would have given it back. Any idea, why? yes, you do that implicitly in \textQEDendingNonProof : its last command is \endgraf , which is basically the same as \par , star...
