Resent Issues for Exam paper questions

Today, before few minutes before I wrote the Bio renewable end semester exam. The following article was based for the 5th question.

Article :UN food chief says world's poorest can't afford food because of soaring prices


Read the Article

UN food chief has stated many reasons to food price increases and garbing food resources for bio renewable fuels was also one reason. Food price increases in Sri Lanka is also stated in that article.

"WFP said Sri Lanka's government reported a 50 percent price increase for rice and a 62 percent jump for wheat flour last year. "

It was amazing to have a recent topic which affect global scale on exam paper and have to add our views which offer full marks.

Read the article and add your comments. My comment will be on this blog after finishing the exam.

Happy Birth Day CPE

The Department of Chemical & Process Engineering was inaugurated by gazette notification on 15th February 1972 as a Department of the Katubedda Campus of the University of Ceylon. So today our department is 36 years now. Many happy returns of the day CPE, the 36 birthday is very much important because we are soon to move new location with state of art research facilities.

Name for ExoMars Robot Rover - "Yenny Iyer"

The boss of the European Space Agency Jean Jacques Dordian has aksed his officers to give a name for robot rover of ExoMars project which is to be launched in 2013. Mr. Jean Jacques Dordian has changed the concept of rover radically and asked ministers to doubled the project cost which was scheduled to 650 million euro.

Since we are sure that there is no complex living being over there, why people waste such a price to explore Mars. Why developed countries not invest money to solve problems in under developed countries. It is their responsibility. Because most of problems are side effects of developed countries wealth flows.

People search over moon, mars and total space. Please search first of all on this world that how many people dies because of hunger, how many children are trafficking for child sex or child slavery, how many infants dies because of preventable diseases such as diarrhea, .... etc. Please invest money to build actual infrastructures to realize Millenium Development Goals.

Mr. Jean Jacques Dordian has asked his officials to make a name. So I am not a person to suggest a name.But I like to suggest a name for that robot rover of ExoMars. Name is "Yenny Iyer". What is the speciallty of this name. This is a child's name who dead due to hunger while I am writing this post. Try find out names of people dead list while you are reading this blog post by paying a visit on this web site.

Matlab Tutorial classes begin

Yesterday Matlab tutorial classes began. We learned the basics of solving differential equations and integral functions. Solving differential and integral function with matlab quite difficult at the very beginning but I try it independently.

Some .m files which are written by me. Do not evaluate me‼‼‼ this is only a beginning……..

x = 0:0.1:10;

y= length(x);

for I=1:y;

m(I)= [x(end-I)];



Second Problem

Solving integral from 0 to 1 ,ydx where y=x

x = linspace(0,1,10);

h = 0.01;



n= (a-b)/h;



for I = 1:n;

x(I+1)= x(I)+h;

y(I+1)= y(I)+ h*x(I);




This .m file did not run, it gives a error message

Are there any MATLAB experts? Help me via comments

Norochcholai Coal Power Plant – Do we need it? Or Not

In order to fulfill the future electricity demand and reduce the production cost of electricity unit Sri Lankan government is building a coal power plant in Norochcholai. Norochcholai is situated in Puttalam district. In previous Saturday our students who follow Total Environment Quality Management visited there and did a simple EIA (only for practice EIA procedures).

The Norochcholai area is not very populated area, but there were many farmlands including tobacco farms and fisherman houses in that area. Raigam Slattern and government Slattern were in the near by area. Agriculture, animal husbandry and fishing are main livelihood of the people in that area.

Now the first phase of the coal power plant project is being done. The initial construction of 300 MW power plant (it is proposed to expand the capacity up to 900 MW). The project output will be 1658 Gwh of Annual Energy to national grid to fulfill the ever increasing demand for electricity.

Actually we are very too much late to install a coal power plant. Literature survey I did over internet show me that the using coal power for power generation is further not used by developed countries. That means they continue their older plants but no more new ones. However, this factor is not a very much strong argument to say “NO FOR COAL POWER PLANT”. Because we are not a developed country and we do not have any of coal powered thermal plant in country. I strongly believe that we need this cheap power generation technology to reduce the cost of energy production.

When I say I like this coal powered thermal plant to be build, one of my friend Dinuka asked me, “What is your opinion if you are a neighbor or victim of the project area ” This is somewhat tough question to reply. But if government bodies doing Social Impact Assessments and resettle us in proper place with enough compensation and use clean coal power thermal plant technologies, there is no point to disagree with the project.

If some one against this project because of environment pollution, first of all they must be protest about air pollution by vehicles, ground and surface water pollution from service stations. People will laugh at the writer, inexperienced chemical and process engineering Student who compares vehicles and 300 MW power plant. However, do not forget there are several hundred thousand vehicles in Sri Lanka and most of them are not in proper conditions. After you, travel in Colombo city roads in a bus, bike, or any vehicle with open window; use a tissue and rube your face. You can see huge amount of dust on it. That is carbon and other dust particles. There are many invisible gases and particles such as COx, NOx, SOx …etc. While having island wide distributed pollution mechanism and we are making controversial on this project which is situated near by ocean.

There are many reasons behind the against on this project. Political agendas, financial tactics of other technological giants (who are specialized in diesel power plants, wind power,…. etc); however every one put environment pollution as the main point. There are other points such as officers corruptions, depletion of coal in world, coal is not available in Sri Lanka, …etc.

But there is strong argument which I also agreed. The power generated by this plant must be used for development of our country. Not behalf of foreign investors. So there must be plans to set up and boost local investment in BOI Zones and sell them energy at lower cost but not to the foreign investors.

Anyhow we must be hurry to set up strong mechanism to ensure environment protection at the best and to realize the development dream of the country.
