XML Table!!

 Ggggoooooooodddddd eeeeevvveeeening!!!

Yo.This is The Don,here to inform you about the latest and greatest in modern computer technology!Today we're going to learn about a cool new language.No,it's not a language I invented myself,mind you.It's called XML,and it stands for Extended Markup Language(NOT Extreme Markup Language,you nerd jokers.)Anyway,what the hell is XML?XML is a language used on the Internet to store data on the Internet.Unlike HTML,which its primary concerns are the display of data.XML is a useful tool that is used in many computer softwares nowadays.Not only it is versatile,but it also allows the use of Unicode for multiple languages,which means people all around the globe can use XML!Here are some examples of an XML notation,take a look!

There!You see-was that too hard to understand??So,basically,we can see that XML IS SIMILAR TO HTML IN LANGUAGE BUT NOT IN DATA FUNCTION. To clearly differentiate more on XML and HTML,why don't we look at a table that describes the differences??

XML	HTML
Concerned with the transport of data only	Concerned with the display of data
Data can be separated from HTML	Data cannot be separated
Can invent your own tags	Tags are pre-determined
Just plain text	Not just plain text

Thus,the differences between XML and HTML are clear-cut.You just have to be a bit knowledgeable in HTML first before you can draft an XML table.XML is very easy to learn.

Behold the XML flow chart!

And that ends our session for today!Thank you,and goodnight!For more information,log on towww.xml.com!

MICROSOFT EXCEL

Greetings,earthlings!

Today,I,the fabulous and awesome Mr Don will teach you ignorant ones about an application known as Microsoft Excel!Listen up!

Microsoft Excel is a spreadsheet application featured in Microsoft Windows and Mac OS X.It features calculation,graphing tools,pivot tables and many more.The main use of Microsoft Excel today is for chart/graph drawing purposes,logbooks,account/ledger informations and many more!It's really a useful tool!

Microsoft Excel uses a unique programming language called VBA(Visual Basic for Applications).VBA programming allows manipulation with spreadsheets that are impossible to do with standard spreadsheets software.As of the 21st century,Excel has evolved from just another program into a powerful application that is capable of doing multiple amounts of work at one time.It also has included some new and cool features since its first creation.So,you see,earthlings,Microsoft Excel is truly a useful program to use whenever you are doing a spreadsheet.Here's a table listing the further advantages of Excel and its disadvantages.

Advantages	Disadvantages
VBA programming allows manipulation of many spreadsheets,which may be impossible to do with the normal spreadsheet software	VBA programming language might be difficult to understand for some people.
Allows you to edit or change the outlook of one or more spreadsheets.	Those using the older versions of Excel can find it more difficult to use the newer versions
Can also be used for some non-spreadsheet works such as a document or a graph presentation.	Excel has only a limited number of file extensions that can be used to save the documents.

That's it for my presentation in Excel!I hope that you have liked it as much as I did!Farewell,earthlings!For more information,log on to http://office.microsoft.com/en-us/ !Cheerio!                              

Chem Sketch.Chem Sketch.Chem Sketch.

   Today I'm doing triple posts!!!HAHAHAHA!!!

 Without further adue,I'd like to present you to my homie and best friend,Chem Sketch!

 (APPLAUSE!)

 Wait......what the hell is a Chemsketch??

 Well,to put it simply,my ignorant friends,Chemsketch is an application that allows you to draw complex molecular structures of certain chemical molecules easily.It also allows you to edit,change and have fun with a whole lotta those boring chemical structures!Tell you what,since you're new to this,how about I give you....a table!Yes,folks,a table regarding the functions and advantages of my dear old friend Chemsketch!Here we gooo!                          

Functions	Advantages
Used to draw multiple chemical structures.	Can draw these molecules very easily with the help of several tools in Chemsketch.
Can view present chemical structures and edit them according to your needs.	Has links to a database that allows you to see many chemical formulae and their structures.
Also allows you to view and draw complex experimental apparatus set-up.	Has many reference tools to allow you to correct your drawings.

 
There you have it folks,a basic outline of what Chemsketch does and its advantages.You can also check out www.acdlabs.com  to find out more information about Chemsketch or go to www.acdlabs.com/download to download it to your computer.

Try it now,folks!Not only does Chemsketch allow you to draw,you can mess around and have fun with chemical formulaes too!Wheeeee!!                    

PDB FILES!!!

Looks like a really bad hair day.........

Too many balls & sticks......

 Yo,yo,yo!Your brother,friend and fellow blogger Mr.Don is back!How's it been?For those of you who don't know,finals are just around the corner,so let's get studying!KOS1110 may be togh,but in the end,I'm sure all this will be worth it!
 But enough of my ramblings for today.Wanna know what I'm thinking now??I'm thinking about......hmmm......
PDB!!"Now wait just a darn minute.I ain't here to read more about acronyms!"you say.Well,my fellow brethren,PDB IS an acronym,but we're not here to learn about acronyms.Nosiree.Instead,PDB for me is a file extension.You know,the little things at the end of files when you save them?For example,picture files can be saved as .jpg or .GIF files?Yeah,that's the one.However PDB isn't your normal file extension.PDB stands for Protein Data Bank.Basically,a PDB file is one which enables pictures of protein structure,chains ,models and many more items related to protein structure to be saved in one file.Let's take a more indepth look at PDB,shall we?
  The history of PDB is a long one.PDB arises from a community discussion about how to store an archive of known protein molecules at that era.This eventually led to a meeting in Cold Springs Harbor about protein crystallography.Finally as a result of painstaking collaboration from the scientists,in 1971 PDB was established at Brookhaven.At that time,PDB had only 7 structures in its databank.As the 1980's rolled in,PDB was upgraded.How?The technology increase at that time led to many number of protein structures discovered and added to the PDB.Furthermore,community discussions about requiring protein structure depositions in the PDB led to a guideline being established by the IUCr.Then,as the 21st century drew close,
PDB was moved to RCSB( Research Collaboratory for Structural Bioinformatics) and finally in the year 2000,wwPDB was formed.Phew-what a long history!
  But the basic mission of PDB,however,is to maintain a single archive of macromelecular data that is freely available to the public.However,since PDB is needed to be regulated,a PDB member now acts as the archive keeper for the PDB(RCSB,again.Monopoly,anyone?)Members have to issue unique PDB ID's to access the data in PDB and they also have strict redistribution rules to avoid misuse of PDB.
Among the data that can be deposited to the PDB is like NMR Data,electron microscopic maps,protein structure and models and many more.These PDB files can be viewed using an application,like RasMol or RasWin.These are molecular visualization software that allow you to see the structure of proteins in the PDB,and can also display it in many modes such as ball-and-stick or ribbon mode.PDB truly is useful!
 If you want to know more about PDB,just go to this website:www.pdb.org.  It is a website that allows you to view the many sources of protein structures submitted by scientists for public viewing and also enables you to download these files.For RasMol and other interrealted software,check outrasmol.org.
You can download  the application easily here.
 After viewing all this,I'll be surprised if you aren't interested in PDB yet.It's really,really useful,man.
Just try it-you won't be sorry.Furthermore,It has a whole lotta advantages rather than conventional sources of protein structures.As such,I'd like to end my post with a table detailing the advatages of PDB against conventional protein data banks.Peace out!

 

PDB	Conventional Sources
Very easy to search for protein structures that you want.	Very difficult to search.
All of the files in PDB are available to the public.	Some files are not available to the public.
Searching for protein structure is fast with the help of a vast database.	The database is quite limited.

SMILES!!!

Hmmm......smiling.


Smiles.You can't live without it,you know?As a wise man once said,"smiles makes the world go round."
But do you know that smiles does not only stand for smiling??It's also an acronym for Simplified Molecular Input Line Entry Specification.It's an easy system that allows you to view the simplified form of molecular formulae.A website tells you more about smiles-just log on to the internet and type in www.daylight.com/dayhtml/doc/theory/theory.smiles.html. 
Here,it shows you a whole lotta stuff such as smiles parentheses,the way smiles is used,common smiles symbols and so much more.You can learn a lot from these smiles,definitely.Want some more proof?How about this-a table!Yes folks,we have another table detailing the advantages of smiles over normal molecular formulae.

 
You sometimes have to refer to IUPAC guidebook to determine the name of a molecule just from its formula.

Smiles	Normal Chemical Formulae
Simplifies greatly the need for long chemical formulae.	Long chemical formulae are sometimes needed to determine the name of a chemical structure.
Usage of symbols to denote bonds.	No chemical bonds can be seen in the noraml chemical formulae.
Enables us to understand chemical formulae faster.
Slightly confusing.	Very confusing

There you have it folks.A very,very short summary on the usage of Smiles and its advantages over normal Chemical formulae.So basically,SMILES are just very shortened chemical formulae.I hope that I can grow to like it soon,because I sure as hell don't sometimes!

MAPLE

Hmm.Maple,Maple,Maple.The name is not so much unique that I've repeated it 3 times.Why?Just for fun.Anyways,when you hear the word "maple" you're instantly reminded of the tree.Or its leaf,which is used as a symbol in the Canadian flag(maple trees are pretty big there).You're also reminded of the maple syrup,which is a staple condiment to add to pancakes.Speaking of pancakes,I'm feeling hungry......food.....need to.....eat......yum...........WOWZA!Phew,almost got sidetracked there for a moment.
   Anyway,the maple I'm talking about's not a tree nor a syrup.It's actually a software!
GASP!I hear you say."Whazzat?Maple's a software?"you ask.Yes,folks,the name Maple is synoymous to a software that's been around for ages.Basically,it's a glorified calculator that allows you to perform complex mathematical functions such as adding,subtracting,division,multiplication,algebraic operations,differentiation and intergration,calculus,trigonometry and so much more.It's every mathematic nerd's wet dream.Yet,for a calculator that can actually give you answers to those stinky calculus problems you were having in class it's actually pretty basic.
   I've been taking Maple as one of the components of my KOS1110(Computers In Science)course in my university,UIAM.At first glance,let me tell you,it wasn't easy.Over the course of 3-4 months I've been studying Maple,and yet I can't grasp some of the concepts there.Maple has its own special programming language that we need to understand and study in order to perform calculations well in its software.For beginners especially,you need a guide to understand these complex programming language.Graphs too,need a programming language to draw it in Maple,so therefore it can be quite difficult and frustrating for beginners.
  This leads us to a question.If Maple is so difficult,then why bother using it?Actually the Maple software and your normal average,everyday scientific calculator have things in common but have differences as far as an ocean.Maple proves to be advantageous despite its setbacks.Take a look at this here table,and then you shall be enlightened,my loyal disciple.
                     

Advantages	Disadvantages
Can perform multiple operations at once	Need a special programming language to understand
Can solve very complex algebraic equations	Very difficult to master
Can solve all kinds of mathematical equations	-
Can be used in all kinds of fields	-

Therefore,here you can clearly see that the advantages of Maple far outweighs its disadvantages.The think-tanks (*cough* nerds *cough*)also have developed a simple(read:simple for NERDS)guide to the Maple software.All you need to know about Maple is right here.You can check it out at my link here at www.maplesoft.com/view.aspx?sl=32469.  Unfortunately it's in Adobe format so,you have to download it to your computer to view it.Here,you can view this 100 page-long book about Maple,Maple programming,programming language and other stuff.(Note:don't read all of it at once unless you have too much free time on your hands).So,by all means folks,get your Maple software today!
   So,that's it for my post.Hope you enjoyed reading it.I had a fun time writing it too.I hope you enjoyed my post!Well,until next time!Auf wiedersehen!


One the friggin' hard claculations that can be done in Maple.



The first thing you see when you start Maple 12.

Ahlan Wasahlan!

In the name of Allah,the Most Gracious and the most Merciful.
