xmL

      My entry today is about XML. XML was designed to describe data and focus what data is. XML stands for Extensible Markup Language.Is a markup language much like HTML. Uses a DTD or an XML schema to describe the data. With a DTD or XML Schema is designed to self-descriptive. My assignment today is about creating XML tree, XML table and XML documentation. below are all my work. 

MEDICINE	SCIENCE
PATHOLOGY	BIO MEDCINE
32	100
40	50
HTAA	GOMBAK

The below XML documentation represents the table above:

<UNIVERSITY>
 <FACULTY = "MEDICINE">

   <DEPARTMENT = "PATHOLOGY">

   <STUDENTS = "32">

   <STAFF = "40">

   <LOCATION = "HTAA">

 </FACULTY>

<FACULTY = "SCIENCE">

   <DEPARTMENT = "BIO MEDICINE">

   <STUDENTS = "100">

   <STAFF = "50">

   <LOCATION = "GOMBAK">

 </FACULTY>

</UNIVERSITY>


This provided link will show you more about XML. Try yourself!

excel

We've learn about the scatter plot in excel.Below are several objectives of learning excel.

objectives

Enter and format data in an Excel spreadsheet in a form appropriate for graphing Create a scatter plot from spreadsheet data Insert a linear regression line (trendline) into the scatter plot Use the slope/intercept formula for the regression line to calculate a x value for a known y value Explore curve fitting to scatterplot data Create a connected point (line) graph Place a reference line in a graph

If you click this link, you will be able to know more about excel.
Below are some of my work done by using excel.

Beer's Law

Titration of 50 mL of 0.1M HCL with 0.1M NaOH

Titration of 50 mL of 0.1M HCL with 0.1M NaOH

The graph of temperature versus percentage injured

The graph of year versus housing start

chemsketch

Chemsketch is about drawing chemical structures and graphical image.In this topic,we learnt how to use Draw mode tools for creating the following objects.

Creating graphical objects

A diagram of the energy of reaction Various types of orbitals Vacuum distillation apparatus A two-chain DNA strand Lipids and micelles

I have try so hard to accomplish this  tutorial and finally done. Below are my works.

PDB

    My post today is about Protein Data Bank (PDB). The data, typically obtained by x-ray crystallography or NMR spectroscopy and submitted by biologists and biochemists from around the world, are freely accessible on the internet. The PDB is overseen by an organization called the Worldwide Protein Data Bank,wwPDB.

The PDB archive contains information about experimentally-determined structures of proteins, nucleic acids, and complex assemblies.The RCSB PDB also provides a variety of tools and resources. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. These molecules are visualized, downloaded, and analyzed by users who range from students to specialized scientists.

    By using Raswin or Rasmol software, we can see the 3-D structural data of large biological molecules, such as nucleic acids and proteins. Any molecule can be seen in 3-D view from many side. Just click and drag the mouse and then the molecule will start to change it's shape. As you can see below,these four pictures represent the same molecules but in different structure.

 If you go to this url , try to type lonA at the search box. Then you'll find out below protein is one of the example of lonA protein.

Crystal structures of Bacillus subtilis Lon protease

Below are some of information about structure displayed above.

Smiles

 Today,I've learn how to draw simple molecular structure by using The simplified molecular input line entry specification or SMILE. If you want to know more about SMILE,you can click this url  to experience your self . As you can see below,those are all my work. In Picture 1, I write the molecular formula of each compound  manually. 
And in Picture 2,3, and 4 I' ve draw the molecules by using chemsketch software.

Table below are some  features that we learn in SMILE.

SMILES Charges	SMILES Bonds
[H+]	Chloroethene
[OH-]	Ethene
[OH3+]	1,1-Dichloroethane

I hope that you will enjoy yourself!
