Question
The natural life span of a domesticated horse is about 25 – 30 years, 10 years down from what it was in the wild. You can tell a horse’s age from the number of teeth he has. They get all their teeth by the age of 5, after which those teeth just get longer. Horses have close to 360 degree all round vision. The only place they cannot see is directly behind or right in front of themselves, which is why it’s dangerous to stand behind a horse. If they later I it also means that they cannot see a jump once they are about four feet from it, and have to rely on memory as to its height and shape! Each of the horse’s two eyes work independently wherever a horse’s ear points is where the horse is looking. A horse is able to sleep standing up as he is able to lock his leg muscles so that he dosen’t fall asleep. Nor do all horses in the same field ever lie down at once – one animal always stands “on look out” duty.

One of the greatest advances in modern technology has been the invention of computers. They are widely used in industries and in universities. Now there is hardly any sphere of human life where computers have not been pressed into service of man. We are heading fast towards the day when a computer will be as much part of man's daily life as a telephone or a calculator.
Computers are capable of doing extremely complicated work in all branches of learning. They can solve the most complex mathematical problems or put thousands of unrelated facts in order. These machines can be put to varied uses. For instance, they can provide information on the best way to prevent traffic jams. This whole process by which machines can be used to work for us has been called 'automation'. In the future 'automation' may enable human beings to enjoy more leisure than they do today. The coming of automation is bound to have important social consequences.
Some years ago an expert on automation, Sir Leon Bagrit, pointed out that it was a mistake to believe that these machines could 'think'. There is no possibility that human beings will be "controlled by machines". Though computers are capable of learning from their mistakes and improving on their performance, they need detailed instructions from human beings to operate. They can never, as it were, lead independent lives or "rule the world" by making decisions of their own.
Sir Leon said that in future, computers would be developed which would be small enough to carry in the pocket. Ordinary people would then be able to use them to obtain valuable information. Computers could be plugged into a national network and be used like radios. For instance, people going on holiday could be informed about weather conditions. Car drivers can be given alternative routes when there are traffic jams. It will also be possible to make tiny translating machines. This will enable people who do not share a common language to talk to each other without any difficulty or to read foreign publications.

Read the passage given below :
Kausani is situated at a height of 6,075 feet in the Central Himalayas. It is an unusally attractive little town. It covers just about 5.2 sq. kms. It lies to the north of Almora in Uttarakhand's picturesque kumaon region.
Kausani provides the 300-km wide breathtaking view of the Himalayas. It is the most striking aspect of the place. Snow-capped peaks are spread in a stately row. They stare at you in silvery white majesty. The most famous peak on view is Nanda Devi, the second highest mountain in India. It is situated at a height of 25.645 feet and 36 miles away as the crow files. The other famous peaks on view are choukhamba (23,420 feet) and Trishul (23,360 feet). Then there are also Nilkanth, Nandaghunti, Nandaghat and Nandakot. On a clear day, the blue of the sky makes a splendid background to these peaks. At sunrise and at sunset, when the colour changes to a golden orange, the scene gets etched in your memory.
When Gandhiji visited this place in 1929, its scenic beauty held him spellbound. He named it the 'Switzerland of Indian'. He prolonged his two-day stay to fourteen days, making time to write a book, 'Anashakti Yoga'. The place where he was staying was originally a guest-house of the tea estate. It was renamed 'Anashakti Ashram' after the book.
Kausani is the birthplace of Sumitranandan Pant, India's poet laureate. Its natural surroundings inspired many of his poems. Its tea gardens mingle with dense pine forests and fruit orchards. The area is also host to many fairs and religious caremonies. If Uttaranchal is the abode of gods, Kausani is God's own backyard. There is no traffic, no one is in a hurry. If serenity could be put on a canvas, the picture would resemble Kausani.

Read the passage given below:
1. I rested for a moment at the door of Anand Bhawan, on Market Road, where coffee-drinkers and tiffin-eaters sat still at their tables, uttering low moans on seeing me. I wanted to assure them, "Don't mind me, you hugging the cash box − you are a coward, afraid even to breathe. Go on, count the cash, if that is your pleasure. I just want to watch, that's all. If my tail trails down to the street, if I am blocking your threshold, it is because, I'm told, I'm eleven feet tip to tail. I can't help it. I'm not out to kill − I'm too full. I found a green pasture full of food on my way. I won't attack until I feel hungry again. Tigers attack only when they feel hungry, unlike human beings who slaughter one another without purpose or hunger."
2. To the great delight of children, schools were being hurriedly closed. Children of all ages and sizes were running helter-skelter, screaming joyously. "No school, no school. Tiger, tiger!" They were shouting and laughing and even enjoying being scared. They seemed to welcome me. I felt like joining them. So I bounded away from the restaurant door. I walked along with them, at which they cried, 'The tiger is coming to eat us; let us get back to school!"
3. I followed them through their school gate while they ran up and shut themselves in the school hall securely. I climbed up the steps of the school, saw an open door at the far end of a veranda, and walked in. It happened to be the headmaster's room. I noticed a very dignified man jumping on the table and heaving himself up into an attic. I walked in and flung myself on the cool floor, having a special liking for cool stone floors.
4. As I drowsed, I was aware of cautious steps and hushed voices all around. I was in no mood to bother about anything. All I wanted was a little moment of sleep; the daylight was very bright.

My mother was still managing Green's, even though its days were numbered. The day after my return I joined her in the small office, where she sat behind her over-large desk, telephone on her right and the latest paperback western before her, ready to be taken up when noting much was happening – which was fairly often. My mother enjoyed reading westerns-particularly Luke Short, Max Brand, and Clarence E Mulfordmuch in the same way that I enjoyed detective fiction. Both genres were freely available in cheap collins ‘White Circle’, edition published during and just after the War.
We discussed the affair of the skeleton in the cupboard, but as there was no longer any mystery about it, there was nothing for me to investigate. However, armed with the key to the store room, I went down to the basement on my own and made a thorough search of all the old furniture, on the offchance that another skeleton moght tumble out of a cupboard or be found jammed into a drawer or trunk. I did find some old tennis rackets, back numbers of Punch, a cracked china chamber-pot, some old postcards of Darjeeling and Simla, and a framed photograph of King Edward the Seventh. I took the copies of ‘Punch’ to my room and read the reviews of all the plays that had been running in London between 1926 and 1930, thus becoming an authority on the theatre in England of that period.

Urea is a major product of nitrogen metabolism in humans. It is eliminated from the body mainly by the kidneys through urine. Urea levels in body fluids, such as blood and saliva, rise drastically under certain kidney dysfunctions. Heart failure, hypovolemic shock, gastrointestinal bleeding, and severe infections can also lead to a rise. Thus urea in blood and saliva provides key information on renal function and helps diagnose various disorders. Most methods for estimating urea in body fluids are based on colorimetry. These methods are time-consuming and involve painful blood extraction. Collecting saliva is non-evasive and research has correlated salivary and blood urea levels. Recently scientists from the IIT-D and the AIIMS, New Delhi successfully developed a smartphone-based optical biosensor to detect urea in saliva. To fabricate the sensor, they directly immobilised the urease enzyme with a pH indicator on a filter paper-based strip. As a response to the urea on saliva, the paper strip changes colour. The red, green and blue levels help measure urea concentration. The scientists used the slope method, sensor response change per unit time, instead of the differential method, the difference in sensor response between two-time intervals, to increase sensitivity and eliminate interference by variations in ambient light. The team clinically validated spiked saliva samples and samples from healthy volunteers. The smartphone application with paper strip can even be operated by non-professional with limited training. This saves time and cost spent on bulky spectroscopic procedures. The report can revolutionise the medical screening of large populations. And such mass screening of diseases would boost national health. |
