Paula,

I’m confident that what you have there is a zero (despite the slightly frustrating font change).

I particularly think this is true because of the A+(−A) = 0 equation that appears in another part of the text.

Thank you for asking!

James,

I see what you’ve done there. You’ve captured the concept that print is presenting.

Nemeth Code does not provide rules for this sort of cancellation/borrowing combo. As you’ve discovered and utilized, it does provide tools for multiple cancellations and even multiple levels of cancellation.

If you do as you’ve suggested in your attachment, using cancellation and replacement where print carries “backwards,” you must make the change abundantly clear in a transcriber’s note.

Thank you for the question!

Greetings, Shelley!

It would be incorrect to keep Nemeth Code open until the end of that sentence.

Would it be giving the braille reader inaccurate content? No. Would it present a major stumbling block to the braille reader? Likely not.

If a chunk of Nemeth Code material followed after this sentence, it would probably be correct and appropriate to leave Nemeth Code in effect through the single word "or" and the simple, unmodified number 315 so that Nemeth Code could be continued for that theoretical following chunk of Nemeth Code material.

Nonetheless, in the example as it is given, leaving Nemeth Code open would be an inappropriate application of the guidance we have for placement of code switch indicators.

Thank you for passing along this question!

Thank you for your question, Angela.

Yes, that’s what I would do with the abbreviation C for Celsius in your example.

–Kyle

[kdejute]

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.
