For an “i” that stands for the imaginary number, use the letter i. As long as print doesn’t have any other i’s in technical context (and that is 99.9% of the time), do not use any emphasis or typeform for the i. Follow Nemeth Code rules for letters and the use/non-use of the English letter indicator as usual.

Thank you for the question!

Good day and thank you for your question, Cheryl.

What you entered in your question I would braille as follows:

⠨⠠⠙⠠⠓⠧⠁⠏⠀⠨⠅⠀⠍⠷⠆⠆⠢⠔⠀⠰⠠⠚⠸⠌⠰⠛⠾

⠨⠠⠙⠠⠓⠋⠥⠎⠀⠨⠅⠀⠍⠷⠒⠒⠲⠀⠰⠠⠚⠸⠌⠰⠛⠾

 

You said you have examples where  ⠸⠙⠠⠓  and  ⠨⠠⠓  are used for ΔH ("Delta H"). I do not know why that is.

The document attached in two file formats shows common print presentations of your examples and their corresponding transcriptions in simbraille.

I hope this is helpful.

Thank you for passing along this question, Cindy. My reply follows.

I understand the temptation to use an equals sign that does not require a switch to Nemeth Code. However, I must point to the first sentence in #1  under Basic Guidance on When to Switch from the Guidance for Transcription Using the Nemeth Code within UEB Contexts (Approved April 2018).  It says (bold added):

Any mathematical expression or chemical formula is transcribed in Nemeth Code. This includes fragmentary expressions, (parts of formulas, incomplete equations, and the like) including isolated signs of operation or comparison.

So, for the print equals signs, we must use the Nemeth Code equals symbol, and we must include within the switch indicators the whole equation (i.e., the codon and, uncontracted, the amino acid).

–Kyle

[kdejute]

Tung,

1. Yes! Your transcription is quite correct.
2. Indeed.You terminated Nemeth Code in precisely the appropriate location.

Thank you for your questions, and thank you for including the print, some surrounding print, and your suggested braille.

–Kyle

[kdejute]

Good questions. In pulling together the following response, I consulted Lesson 16 of the Provisional Revised Nemeth Course Manual, especially pages and 16-11, 16-12, and 16-31.

The attached image shows the format that I would suggest. It treats the system of equations not as displayed material but as a continuation of the text, as it appears to be formatted in print.

The attached image whose file name begins with a 2 shows a pooossssible alternative, which treats the system of equations as displayed material, with the remark printed to the right of a system of equations that doesn't have an enlarged right grouping symbol brailled on a line separate from the system.

Thank you for your question! You're tackling a sticky issue, with quite accurate dots!

What signals a braille reader that an abbreviation followed by a period is just that and not a letter followed by a subscript 4? The short answer is "space."

Consider the examples "21 m. superscript 3" versus "21 m subscript 4 superscript 3". In braille, the first will have a blank cell between the 21 and the m., while the second will not. See the attached document for this example presented in a less verbose way.

The slightly longer answer to your question is "sometimes space, sometimes context." For example, "m. superscript 5" and "m subscript 4 superscript 5" without any other content or context have exactly the same braille dot configurations. But for the braille reader, there will always be surrounding content (e.g., in the first example in this message, there is the 21). On the off chance that there is NO surrounding content, just nothingness as far as the fingers can feel, then it is our job as transcribers to do something (i.e., insert a transcriber's note).

Thank you for your question!

A blank cell must always follow an opening Nemeth Code indicator, and a blank cell must always precede a Nemeth Code terminator; these blank cells do not represent any space in print. The spaces in print are transcribed separately.

So, the appropriate transcriptions for your examples are:

⠼⠁⠲⠀⠐⠣⠸⠩⠀⠼⠆⠬⠆⠀⠨⠅⠀⠼⠲⠀⠸⠱⠀⠯⠀⠹⠀⠊⠎⠀⠮⠀⠋⠥⠇⠇⠀⠁⠝⠎⠺⠻⠲⠐⠜

⠼⠃⠲⠀⠐⠣⠠⠹⠀⠊⠎⠀⠮⠀⠋⠥⠇⠇⠀⠁⠝⠎⠺⠻⠒⠀⠸⠩⠀⠼⠆⠬⠆⠀⠨⠅⠀⠼⠲⠀⠸⠱⠐⠜

where the opening parentheses are not followed by a print space, and the closing parentheses are not preceded by a print space.

Sometimes it helps me to think of the Nemeth switch indicators as three-cell symbols:

• opening Nemeth Code indicator: 456, 146, BlankCell
• Nemeth Code terminator: BlankCell, 456, 156

Thank you for your question! Please do let us know if you have follow-up concerns.

Your instances of “Delta H equals something” are separate equations. Each should be preceded by a space to separate them from the chemical reaction. (Delta H etc. is an expression of the change that happened in the preceding reaction.)

–Kyle

[kdejute]

Use Nemeth Code for sets and subsets that are enclosed in grouping symbols. Good catch. Good question.

[kdejute]

These are important questions, and you are certainly not the only transcriber struggling with their like.

I am conferring with others and will get back to you with what thoughts/suggestions we have.

–Kyle

[kdejute]

Good catch!

That definitely looks like a distinction that you should retain. I believe I’d use the script A for the special “Area” A.

[kdejute]

Thank you for your question, Elizabeth.

If I understand correctly, you are transcribing using UEB with NO Nemeth.

Using UEB for technical material, I would use the braille in the attached image and BRF files.

The first and third lines in those transcriptions are opening and closing grade 1 mode (the opening grade 1 passage indicator is a series of three dots 56, which must be preceded by the three-cell dot locator for use; the grade 1 terminator is dots 56, dot 3, and it also must be preceded by the dot locator for use).

The braille cells in the second line are:

• the opening general fraction indicator
• a pair of braille grouping indicators around AC
• the one-cell symbol for "bar over previous item"
• the general fraction line
• a pair of braille grouping indicators around HK
• the one-cell symbol for "bar over previous item"
• the closing general fraction indicator
• blank cell
• the two-cell equals sign
• blank cell
• the opening general fraction indicator
• a pair of braille grouping indicators around BC
• the one-cell symbol for "bar over previous item"
• the general fraction line
• a pair of braille grouping indicators around JK
• the one-cell symbol for "bar over previous item"
• the closing general fraction indicator

Again this is the transcription of your print example using UEB for technical material.

Does this help?

Well, there is not separate guidance or a publication that covers science, as opposed to math, material.

Also, your suggested placement for code switch indicators sounds good.

[kdejute]

Also, it is worth noting that none of the letters we're discussing here is an abbreviation; they are all variables or chemical SYMBOLS.

[kdejute]

Good points and contributions, Kaari. Thank you.
