Friend!

FRIEND is a beautiful word that we use it every day, such as my good friend, hi friend, miss you friend etc. But there is no written definition or regulation for friendship. There isn’t. You won’t find a single written sentence about principles of friendship. This makes it very difficult. Difficult! Because meaning of friendship varies from one person to another one. We all look for friends for different purposes. We try to make friends because they offer something that we don’t have. Because we are weak, we are limited and we can’t have everything by ourselves.

Some of us go after friends because of their money. The easiest thing that we may think of it, It doesn’t matter one pound or 100 pounds. We just go for it. We trade our time for money not for being with other people. Or they are looking for other things, CD, printer, paper, bicycle, accommodation, clothes etc. So will you call it “friendship”? I won’t. I call this group of people “low mind people”, people with low mind which are looking for things in this world.

Well there are other groups as well. A group of us looks for friends for not being alone. They are afraid of going outside alone. So they look for a company. They are more interested in talking about other people. They try to be centre of attraction by talking about others. I call this “Gossiping” not making friends. If we are strong enough and if we have strong character, then we don’t need to do anything to attract the others. Other people will come after us because of our ideas, personality and abilities. I called the second group “people with medium minds”. People who are goes after people for their own benefits. This group of people have lots of friends. It is better to say that they know many people, but few of them are true friends who care for them. I think they loose lots of their friends in time and they are always looking for new people.

And the last group, a group of people with great minds. This group of people are looking for ideas; they look for people with great ideas, strong personality and solid attitude. They usually have few friends, but true ones. They are not interested in abusing their friends. They just enjoy discussing ideas with them. They enjoy being with other people to know their world better. They help their friends by offering them their thoughts and feelings. They like to be with other people to learn from them. Learn to live better. They want to improve and develop their mind. They are true friends.

So at the end, I don’t like call everyone that I know a friend. Let’s read this poem together:

Around the corner I have a friend,
In this great city that has no end,
Yet the days go by and weeks rush on,
And before I know it, a year is gone.
And I never see my old friends face,
For life is a swift and terrible race,
He knows I like him just as well,
As in the days when I rang his bell.
And he rang mine but we were younger then,
And now we are busy, tired men.
Tired of playing a foolish game,
Tired of trying to make a name.
"Tomorrow" I say! "I will call on Jim
Just to show that I'm thinking of him."
But tomorrow comes and tomorrow goes,
And distance between us grows and grows.
Around the corner, yet miles away,
"Here's a telegram sir," "Jim died today."
And that's what we get and deserve in the end.
Around the corner, a vanished friend.

7thWCCE 1

I have to say I am very pleased that I am in this big event. A great place which all great chemical engineers gathered together fot making this world a better place to live in. People from aroung the world are here sharing their experinces without any hesitation. I think we all have learn from that. In addition to that I have seen many Iranians mostly from Zahedan Univeristy. Although the qality of their works is matter of question, there is a hope when you do not find a scientist or engineer from other countries in middle east. I wish all those presenters luck and I hope they understand their responsbility in presenting Iran.

I will write more...

I will be back!

Well, another conference...I am going Glasgow for World Congress of Chemical Engineering. I will return 20th of July and I will write more then.

Friendship Test

What a strange world! One day we are happy and another day we are sad! In our life time we meet people and become friend. Everyone call themselves friend! But there is no written description of friend and friendship. That's why friendship is beautiful. It is like art. You build a relationship. You are painting a great picture. But you should be careful. A black spot may ruin your entire picture. So who are true friends? How can we test them? Is it really important to test them? The answer is up to you! We need to trust someone and because people do not want to take that responsibility maybe because of their own benefits, they may abuse your trust. So at the end you will find yourself alone! Then I think it will be good to examine our friends to see if we can trust them or not although the results may be upsetting. I usually test my friends in my own way and look at the results. Unfortunately some of them may fail. Not because they are bad. That isn't the reason. Because they are looking after something else. They have found their benefit some where else. So they can't be honest with you anymore.

But let me remind you that a true friend does not exchange you easily with his own benefits.

A great fellow told me that a true friend is like a star, always above your head, he is shining for you above your head even in cloudy days, even when you do not look after it.

Just a box!

Yesterday morning I went to the lab. I saw all my bottles and sample tubes are on the floor and their box is gone. Finding another box was an easy job to do. I found another box and returned all of them to the box. I found out that a professor in the department who was looking for a box took the box without asking me. When in a department a professor is behaving like this would you expect students to act differently? What do you call this?

Research time!

One day morning, you wake up, what a lovely day, a sunny day, everthing smiles to you and decide to go you small lab doing an experiment. Yes, I want to do it! I want it and I will. Nothing in the world can stop me...what a good day...Now you are in the lab. You take your sample and you want to weight it..So it is very easy...the easiest thing in the world of scince is weighing if you have a scale...yes scale...I need a scale..But where is it? It used to be there..on the bench..Ask staff if they have seen the scale...yes, the scale is gone..no scale no experiment..the scale is gone!!! Your good day...what a day...

Think about it..Our research environment is very important. Research or Hassle? If you are looking for high quality research then everything should be provided, I mean if you prepare everything, then later you have just think about the procedure and the experiment itself. But here you have to protect your laboratory equipments because other researchers do not give a damn about your project..What a world we are living in..We talk about G8 everyday..we talk about human rights everysecond and then we are simply blind about our behaviour!

Mass transfer of friends

It is matter of freindship..So what's the link to chemical engineering! I have to say nothing! I am going to use this space to express my feeling as I think my relationships and daily life is affecting my research quality!

Maybe you know few people in your life that you know very well they are not true friends, not very bright people and they are upsetting you by their behaviour!But you can't help the situation, as they are in your life! Once you trusted them and now you realised that they are not your type..But it is too late, they have entered circle of trust and taking them off the circle is not easy! Everyday you think how I should help myself in this situation! Shall I ignore them? Shall I fight? Shall I move to another place? How can I change it?

Here, filtering friends usually happens everytime, as we are all changing, we are moving, we are dynamic and our system is not steady state! So there is output and there is input and ofcourse in any system there is accumulation.

So people would enter your system ,exit (input and output of the system) and only and only true friends will be accumulated in your system. Now you should be careful, to take care of system temperature and pressure. You may spoil your system. I would say calculations in this system is very important and do not enter anyone. Also you should be brave enough to remove bugs from the system, so do not shutdown the output flow and leave it on.

Ture friends will be accumulated in the system under any condition.

My sweet little terrorist song

I'm detained
captured "in-framed"
I'm detained
and I destroy
I deny
I'm on a decline
this is just about how I'm definedand I'm a walking weapon
don't touch me couse I just might blow
legally I'm nobody , when I cross the border
I'm somebody meanmy international rights are in some poiticians thought
I'm just a dreamas I turn to this microphone and scream
I just wanna watch Dylan playin' live
I won't fly into Pentagon aliveand if they catch me on a plane from Amsterdom
believe me it's not for any political crime
I'm a living catastrophe
look how imprtant I've becomeand my brother in Palestinehe's even ten times more strong
but when they went to Afghanistanor fly to free Iraq I was singing in my room
when it bloomed in Japanand all the years of Vietnam
I wasn't even bornthis miserable world
we appear on their TV shows like creatures from another planet
if they ever knock on my door,
it's just for the oilor mysteries left from my ancient parents
I got my friend in California I die to see her but I can'tand my sweet cousin in Parisshe just wants to show me around
I'm detained
captured "in-framed"
I'm detained
from the AXES OF EVIL
I'm the right hand of the devil
I'm a terrorist though I haven't killed anyone yet
I'm a suicidal bomb, be careful, I might go off in the end of this song

So far So good!

Remember Modelling Story, well I am still busy with it! The main question to answer is why modelling? We model a system to predict system's behaviour with out doing any experimnetal work. If that is the answer, them I have got. For Estimation of trace elements release from fly ash three scenarios are provided:

1- Disposal in a percolation release regime
2- Utilisation as granular fill
3- Utilisation in road construction

Now there is use for the model. I am working on my results. Trying to find a way to use information from batch leaching test in order to estimate release of trace elements from fly ash samples under above scenarios. I think I know what I wnat to do. I don't want only to model fly leaching without any aim or objective, just showing my math skills! I was looking for a reason for it and I found it.

So full power ahead to solve it...Let you know the results when I got it.

Double diffuse layer!

Working on a theory to model trace elements release from fly ash particles. Please read:

Solid-liquid mass trasnfer during leaching of Ca from dilut slurries of fly ash

By: R. S. Iyer

1999


Let you know the results later!

Sunny day

Apart from my research, I had a wonderful time in Westorn park, close to the studnet union. I spent an hour there!

Transport processes

Looking to model transport processes from leachtes produced from fly ash lagoons! Well, I have to say that three processes are involved:

1- Advection
2- Hydrodynamic dispersion
3- Chemical recations

For modelling we need to right mass balance equation. It is very simple. The solution depends on your assumptions and it can be a simple diffusion equation to a 3D complex equation. For more details you can read Groundwater by Freeze.

A bottle of Argon

Well, another day, another story! Today I spent almost an hour to get permission to order two bottles of Argon for the ICP-MS equipment! As my supervisor was away today morning, I needed to ask somebody else to sign my order form. I learned that:

Stop doing any experiment and wait till your superviosr comes back!

No wonder some experiments takes so long!!!!!!!!

A visit to Brighton

First of all I learned not to trust BBC weather! or even Yahoo one! Don't ask me, just try it yourself. We double checked Friday weather, BBC said it should be sunny and hot. Well we all left Guildford head to Brighton.

First impression: It was not kind of the city that I expected. It was small and dirty. Even worse than Bradford!!!! I could not believe it, Brighton with beach...Oh you can't call it beach...No Sand...No sun...No babes...Sun No Sun.

Second impression: It has the best Fish and Chips...You don't believe me, try it yourself.

We returned to Guildford around 5 ish and I checked BBC website: it said Brighton is Sunny on Friday!!!

Poker in Guildford!

Playing poker in London with my best friends, far away from research and Lab! I needed it!

New model for batch leaching

Today I developed a new mathematical model for batch leaching test on the basis of Fick's law! Chemical reactions and diffusion have been included in this model. Finger cross for the model which I will put in practice next week!

No more research this weekend!

well, after two days hard work in the lab, carrying out Mass Transfer test and preparing the lab for nex week experiments (Leachin contact time), no more research this bank holiday weekend!

Third yera presentation, After it!

What a wonderful day! It was really great...Well the story: I was had 30 min which the guy before took 10 min of my time! So I had only 20 min for the presentation and question part! So I did it very fast. I talked like hell, a very short introduction, assuming that I am doing in a chemical engineering department, full of chemical engineers! But I slowed down in the rseults and discussion part, the mjor part of my work.

I undestood that no one listened to me! No one red the forst slide! No one knew my name except few people which I appreciate them. My supervisor is a great man, he always supports me and I appreciate his kindness and helps.

But the battle field was the question part, when the assessor asked an old question: Where is your model?

Just read his comment on my presentation:

Needs a outline (PS. I am sure he did not linsten ver well)
Thesis should have clear modelling and analysis of equilibrum.diffusion.

I have to add that in this project modelling was in the pbjectives. But I included Mass Transfer tests. Well, in reality, it is impossible to model leachability of trace elements from fly ash, where structure of a fly ash to another one is different. On the other hand, it will be useless to model leaching when the model will be applied on only one type of fly ash! There is no point in modelling fly ash leaching when to can not generilise it. I think the assessor does not know about these facts. He is assessing the project from his point of view and I strongly disagree with him.

Check it out!

Third year presentation

Tomoroow I have to give a presentation on my PhD research. I am going to talk about batch leaching tests (Availability, TCLP and BS EN tests). I believe these tests do not present actual scenario happing in the environment! We need to design more real tests close to the enviornmnetal conditions. In addition to these, I will talk about leaching behaviour of UK fly ash and effects of pH and LS (Liquid-to-Soild) ratio on leaching process..
