# 0.8 Presentation scripting elements

 Page 1 / 3
Scripting requires changing baseline of scripting character(s).

Mathematical notation requires scripting around a base entity. The MathML provides scripting capability through scripting elements : msub, msup and msubsup. Scripting in MathML is not limited only to putting a subscript or superscript around an expression, but vertically integrated upper and lower scripts, which are handy to display limits on integrals and to meet such other requirements of rendering structured display.

Rendering of script is done by manipulating certain attributes that elements acquire from the environment such as “xml” or “html” document.

## "msub" and "msup" layout scripting elements

$\begin{array}{l}{\text{Specific attributes : }}\left(\mathrm{superscriptshift, superscriptshift}\right)\end{array}$

## Attribute value types

• superscriptshift, superscriptshift (default : automatic) : number v-unit

Each of these scripting elements takes two arguments base and subscript, which may be valid MathML expressions. Syntax of the two elements are as given here :

<msub> base subscript </msub> <msup> base superscript </msup>

Each of these scripting elements takes two arguments base and subscript, which may be valid MathML expressions. Implementation of “msub” element shifts the baseline of the script, while retaining that of the base. In the case of “msup” element, the baseline shifts the script up. In both cases, display style of the scripts are also changed

The amount of shifting can be specified by giving numerical values to “subscriptshift” and “superscriptshift” attributes preferably in "ex" unit. The example here demonstrates implementation of both “msup” and “msub” elements.

## Subscript and supersubscipt

<m:math display="block"> <m:table> <m:mtr> <m:mtd> <m:msup> <m:mi> m </m:mi> <m:mrow> <m:mn> 1 </m:mn> <m:mo> &InvisibleComma; </m:mo> <m:mn> 2 </m:mn> </m:mrow> </m:msup> </m:mtd> </m:mtr> <m:mtr> <m:mtd> <m:msub subscriptshift="1.5ex"> <m:mi> m </m:mi> <m:mrow> <m:mn> 1 </m:mn> <m:mo> &InvisibleComma; </m:mo> <m:mn> 2 </m:mn> </m:mrow> </m:msub> </m:mtd> </m:mtr> </m:table> </m:math>

Save the file after editing as “test.xml”. The display looks like :

$\begin{array}{c}{m}^{12}\\ {m}_{12}\end{array}$

Observe that “&InvisibleComma;” entity reference impart the meaning that scripts is read one two and not as one multiplied by 2.

## "msubsup" layout scripting element

$\begin{array}{l}{\text{Specific attributes : }}\left(\mathrm{subscriptshift},\mathrm{superscriptshift}\right)\end{array}$

## Attribute value types

• subscriptshift (default : automatic) : number v-unit
• superscriptshift (default : automatic) : number v-unit

The element takes three arguments. First argument of the element is base; second argument is subscript; and third argument is superscript. The syntax of the element is :

<msubsup> base subscript superscript </msubsup>

Scripting “msubsup” element affects simultaneous implementation of a subscript and superscript, which are vertically aligned. This is an extremely useful scripting element as this element can be used to display limit values on variety of expression, including an integral sign.

where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
da
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts
Bhagvanji
hey

what is variations in raman spectra for nanomaterials
ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre
nanocopper obvius
Alexandre
what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
