Attribute value types

• numalign (default = center) : left | center | right
• denomalign (default = center) : left | center | right
• bevelled (default = false) : true | false

The “numalign” and “demoalign” affects alignment of numerator and denominator with respect to the bar. In most of the case, we do not change the default “center” element as this is the manner in which expressions are written in mathematics.

The “bevelled” attribute provides an alternate form for rendering fraction. In beveled form, the bar is a slant line, in stead of a horizontal line. This form is useful, when we want to include fraction inside the text as its default form takes more vertical space than that of the text, disturbing line spacing between text lines. More significantly, this reduces vertical space of an intensively nested expression.

Bevelled "mfrac" display

<m:math display="block"> <m:mi> x </m:mi> <m:mo> = </m:mo> <m:mfrac bevelled="true" linethickness="thick"> <m:mrow> <m:mn> 1 </m:mn> <m:mo> + </m:mo> <m:mfrac linethickness="medium"> <m:mn> 3 </m:mn> <m:mn> 10 </m:mn> </m:mfrac> </m:mrow> <m:mrow> <m:mfrac> <m:mn> 2 </m:mn> <m:mn> 7 </m:mn> </m:mfrac> <m:mo> + </m:mo> <m:mfrac> <m:mrow> <m:mfrac bevelled="true" linethickness="medium"> <m:mn> 8 </m:mn> <m:mn> 11 </m:mn> </m:mfrac> </m:mrow> <m:mn> 5 </m:mn> </m:mfrac> </m:mrow> </m:mfrac> </m:math>

The “msqrt” and “mroot” are radical elements. The “msqrt” element renders square root, while “mroot” element represents indices with a base and index.

"msqrt" layout element

The “msqrt” element accepts zero or one argument. Its syntax is :

<msqrt> base </msqrt>

When there are more than one child elements, then they are considered to be enclosed within “mrow” tags. This means that the “msqrt” element draws an inferred implementation of “mrow”. This saves us from coding “mrow” tags explicitly, irrespective of numbers of arguments.

Square root element : msqrt

<m:math display="block"> <m:msqrt> <m:mi>x</m:mi> <m:mo>-</m:mo> <m:mn>3</m:mn> </m:msqrt> </m:math>

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

$\sqrt{x-3}$

Like other elements in MathML, “msqrt” element supports nesting to enclose square root recursively.

Nested square

<m:math display="block"> <m:msqrt> <m:mi>{</m:mi> <m:mi>x</m:mi> <m:mi>+</m:mi> <m:msqrt> <m:mi>(</m:mi> <m:mi>x</m:mi> <m:mi>+</m:mi> <m:mi>10</m:mi> <m:mi>)</m:mi> </m:msqrt> <m:mi>}</m:mi> </m:msqrt> </m:math>

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

$\sqrt{\left\{x+\sqrt{\left(x+\mathrm{10}\right)}\right\}}$

"mroot" layout element

The “mroot” element requires exactly two arguments – the first one as the base and second as index. The syntax of the element is :

<m:mroot> base index </m:mroot>

Each of these arguments may be combination of elements, which must be grouped separately with the help of “mrow” element in two distinct groups.

Indices element : mroot

<m:math display="block"> <m:mroot> <m:mrow> <m:mi>x</m:mi> <m:mo>-</m:mo> <m:mn>3</m:mn> </m:mrow> <m:mfrac> <m:mi>x</m:mi> <m:mn>2</m:mn> </m:mfrac> </m:mroot> </m:math>

$\sqrt[\frac{x}{2}]{x-3}$

do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
Abigail
Do somebody tell me a best nano engineering book for beginners?
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure

On having this app for quite a bit time, Haven't realised there's a chat room in it.
Cied
what is biological synthesis of nanoparticles
what's the easiest and fastest way to the synthesize AgNP?
China
Cied
types of nano material
I start with an easy one. carbon nanotubes woven into a long filament like a string
Porter
many many of nanotubes
Porter
what is the k.e before it land
Yasmin
what is the function of carbon nanotubes?
Cesar
I'm interested in nanotube
Uday
what is nanomaterials​ and their applications of sensors.
what is nano technology
what is system testing?
preparation of nanomaterial
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
what is system testing
what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
Prasenjit
how did you get the value of 2000N.What calculations are needed to arrive at it
