Essay On Malaria Disease Essay On Science Reports Research On Malaria

These was confusion about malaria. Up to recent times people thought that malaria was caused by the unhealthy mists (called -miasma-) that rise from marshy ground at night. The very name "malaria- shows this; for it means -bad air-. But it has been proved that the culprit is not marsh fog, but an insect, the mosquito. It is the bite of mosquitoes, or rather or one kind of mosquito, the Anopheles, that gives people malaria.

Like most other diseases, malaria is due to a tiny germ. This germ multiplying in a person's blood gives him malaria. Now when a mosquito bites a person that has malaria, and sucks his blood, it takes in some malaria germs. When it bites other persons after that, it injects into their blood some of these malaria germs. which give those thus bitten malaria in their turn.

So mosquitoes are carriers of malaria from one person to another. The only real cure for malaria is quinine. When you take quinine, it gets into your blood, and kills the malaria germs there. People who live in malarious districts take quinine as preventative; so that, if they get bitten by mosquitoes, the malaria germs may be killed as soon as they get into the blood before they can breed and multiply. They also take care to sleep under mosquitoes-nets. These protect them from getting bitten by mosquitoes, which are always most active at night.

But the only way to stamp out malaria is to get rid of the mosquitoes. How can this be done? Well, the mosquito begins its life as a tiny grub in water. These grubs are hatched from eggs which the female mosquito lays on the surface of stagnant water. The only way of stamping out mosquitoes is to do away with the mosquitoes' breeding places.

So, standing pools must be drained dry, ditches of stagnant water cleaned out, and wells and rain-water tanks kept covered. When a pool cannot be drained, its surface should be covered with kerosene oil. This prevents mosquitoes from laying their eggs there, and it kills the mosquito grubs in the water by preventing them coming up to the surface to breathe.

If such measures were carried out systematically in any malarious district, mosquitoes would in time be stamped out, as they have been in Panama; and malaria, which is such a scourge in Pakistan. would trouble the people no more.

Essay on A Journey By Train

Last year, during summer vacation, I had an occasion to go to Sukkur. We could have reached Sukkur by bus but it was something tedious as we had to go to Hyderabad by bus and take a wagon bound for Nawab Shah and then at Nawab Shah take another wagon bound for Sukkur. So I decided to go by train. I bought my ticket from railway agency at Gru Mandir and reached Cantonment station half an hour before the departure time. The Mail bound for Rohri was over crowded. Passengers were shouting and trying to get into the railway carriage, since my seat was already booked I got my seat easily.

The train started just at the appointed time. It stopped at Drigh Road, and Malir cantt and then ran for Jung Shahi. I had my seat just near a window and was peeping through it. Vast deserts with no trees or plants ran past me. Gushes of hot wind came through the window and brought with it the grey dust of sand.

The train ran without stopping at Rn Pathani. It stopped for a few minutes at Jung Shahi which appeared deserted. Only two hawkers, and two passengers were there. From Jung shahi the train started for Kotri. Kotri has long platform. Some passengers were getting down and some were trying to board. Hawkers shouted and sold Kabab Roti, biscuits, cakes, pastries, pan and cigarette. Railway coolis were busy in taking luggage down or throwing into the train.

From Kotri the train started and halted at Hyderabad. It was a busy station. Quite a good number of passengers got down the train there. I came out to roam about and see the station. After half an hour, a new engine was attached to the train and the train started again halting at Nawab Shah, Shahdad pur and also at a few more stations. At last it reached Rohri.

Rohri is a junction. It is a big station with many platforms. My bogy was taken off the mail rain and attached to a passenger train bound for Sukkur. The passenger train reached Sukkur at dusk and thus the journey came to an end.

Essay on A Journey By Bus

Last summer, the marriage ceremony of my Uncle’s elder daughter was held at Hyderabad. My family had already gone there and only I was left behind in Karachi because my school had not closed for summer vacation yet. My programmed was to reach Hyderabad a day before the marriage day.

I took my Hyderabad bound bus at 7 a.m. at wood street. At 7:30 the bus started with only a few passengers. It moved a few yards and stopped for passengers who were waiting at the McLeod road corner. Then from Numaish to Sohrab Goth it stopped at every ten or fifteen yards for the passengers till there was no room to stand even and the extra passengers had the honour to sit on the roof.


The sun rose higher and higher and it became hotter and hotter. The wind coming in through the windows was hot and brought dust with it. Every one was perspiring profusely and Was grey with dust. Our first stop was Gharo. There were hotels by the road side where flies swarmed and people spat on the floor. Some passengers got down to take coca cola or tea. After fifteen minutes, the horn of the bus was blown by the driver. The passengers rushed in and the bus started moving.

The next stop of the bus was at Thatta. Here better hotels were seen. Nearly all the passengers got down to take refreshment. I also got down as due to sitting in the bus for about two hours my legs had become numb. I drank a bottle of coca cola to quench the thirst. Flies swarmed there also. After half an hour the bus started again.

The bus again stopped at Shujawal. Thence it ran straight for Hyderabad crossing the Kotri bridge it first stopped near Hyderabad railway station where I got down covered with dust and sweat. I took a Tonga for my uncle’s house and reached quite exhausted. After a cold shower 1 was able to relate the damned Journey.

Essay on Students and Politics

Of late much has been said in pros and cons of the burning question, "Should students take part in politics". A few years ago the supreme court of Pakistan gave their verdict on the question and prohibited the students from taking active part in politics. The government of all the four provinces imposed ban on student’s political organizations. The educational institutions went a step farther and before giving them admission they demanded the students to submit un undertaking that they would not take part in politics. Despite all these steps the things arc not so bright as expected.

We know that anything, if done unscrupulously, will lose its charms and benefits. Even the acts of kindness, generosity and magnanimity become undesirable if not kept within limits and arc performed recklessly. The participation of students in politics is not an exception. Since it has not been done in an appropriate way, and has been given the freedom of crossing all limits, it has become a curse.
Unfortunately, in Pakistan all the major political parties have their baby organizations in schools, colleges, vocational institutes and universities. These organizations have not been reacted with a view to training the students for future but only for serving the political ends and interest of their parent politic all parties. They arc encouraged by their parent bodies to take extreme actions to crush their opponent by violence and to create commotions. The educational institutions are closed for long periods due to their strikes, killings, putting offices to fire, breaking furniture and destroying what things they can lay hands on. And when the culprits are arrested the concerned political parties put up a hue and cry, issue threatening statements and accuse the authorities with the result that the culprits become heroes and get encouragement.

Students have the right to prepare themselves for the future. Some of them would be required in future to lead people politically, to participate in the politics of the country or hold sonic important political office in the government. To prepare themselves for this, they need practical training so that they may prove efficient leaders in future. This training must start on a small scale. They should not be allowed to take active part in the politics of the country and play tools in the hands of senior politicians who serve their political ends by instigating them. In fact the student who participate in the politics of the country and behave like a puppet in the hands of selfish and conscience-less senior politician serve neither themselves nor the country.

Our students arc intelligent. They should realize their duty as a student and should not sacrifice their academic career for politics. They must, first of all, get knowledge, then participate in politics.

They are reasonable, patriotic and selfless. They must not fly to destroy the properties of their institutions or public properties. Their politics must be limited to the affairs of their debating societies and unions for training purpose.

Essay on How to Control Pollution

In the last two or three centuries, science has made great progress. We are living in the age of continuous industrial revolution. We have built vast industries that are providing large quantities of goods and machines.

Millions of factories in all parts of the world are sending huge quantities of carbon dioxide and other poisonous gases in the atmosphere. This is not the whole story. They are pouring continuous streams of harmful chemicals into the rivers of the world. Every hour our cars, buses and aeoplanes are discharging deadly poisons into our atmosphere. There are three kinds of pollutions which we are facing.

1. Atmospheric Pollution
2. Water Pollution
3. Noise Pollution

Efforts are being done to control the pollution throughout the world. The hole of ozone layers is being tried to repair. Many special organization has been made to control the pollution. The electronic and print media is trying to produce complete awareness about the pollution and its causes and about its results in future. I think following attempts can be made to control the pollution.

1. Complete awareness should be provided to people by using electronic and print media.
2. It should be ordered to all factory and mills owners that they must destroy their wastes in the most careful way.
3. Recycling of the wastes should be introduced in factories.
4. The smoke of the transporting vehicles should be controlled by using special devices.
5. The rattling of machines and the pressure horns should be avoided and the noisy process should be controlled.
6. The discharge of the wastes into the rivers should be stopped.

Essay on A City of Problems

Big cities are generally thickly populated all over the world. People from different parts of different parts of a country come to the big cities and they have different natures and constitute a society in a big city, therefore many problems are produced in a big city due to thick population and the different nature of the people. Karachi is the big city of Pakistan and it is rightly called "A City of Problems". Due to thick population and ever expanding quality of Karachi, the life of Karachi has become quite difficult and troubling.

1. There are many problems which we face daily are following.
2. Traffic and transport problems.
3. The problems of frequent power failure of electricity.
4. The problem of short supply of drinking water.
5. The problems of less number of amusement parks and public libraries.
6. The problems of broken roads and lack of speed breakers.
7. The problems of insanitary condition which looks nearly every where.

Majority of the people in Karachi travel in buses, mini buses and coaches which run on the road with full of passengers even the passengers are looking on their roof and hanging outside. Traffic in Karachi is now beyond control. Due to the reckless driving thousands of lives are lost every year. The supply of electric power is inadequate and far from well, low voltage damages the costly electric appliances. The people are looked in great trouble due to the frequent power failure of electricity.

Great rush of people and heavy traffic is a part of life in big cities. So in Karachi the great rush of people and heavy traffic is looked everywhere, here people work like machines. Atmospheric pollution is common due to the smoke of vehicle and the use of chioroflouro carbon. Noise pollution also makes the life of people uneasy.

In Karachi, people are suffered from the short supply of drinking and the daily us of water. The broken roads and insanitary conditions are nearly everywhere which make difficult to move even on foot. Crimes are at peak in Karachi. In buses and wagons pockets are usually picked. Theft, dacoities and burglaries are common. Besides the adulteration, corruption, bribery in offices and violence are the major problem that we face everyday in Karachi. Nowadays homosexuality of young boys and the business of prostitution is increasing. Street beggars are common in Karachi. They get together on the places of amusement and in markets where they try to convince people for their help.

On considering the problems of Karachi as the life in big city, we conclude that the life in big cities has many charms and attractions, it provides many facilities but is also full of mental confusion and worries which destroy the creativity of a person.
