Getting sick overseas can be scary. You're in an unfamiliar place and often don't speak the language. Although each trip is different, there are universal things you can do to keep safe. Be prepared. "Schedule a visit with a doctor who specializes in travel or the area you're visiting at least four weeks before your departure," says WHO public health expert Dr. Gilles Poumerol. A travel doctor will be able to give you the required and recommended vaccinations as well as discuss any medical issues you may come across abroad. Get insurance. "In many countries where you have limited access to health care, good health care is only found in the private sector and can be very expensive," Dr. Poumerol says. Plus, in an emergency, returning to the United States can cost more than $50,000. Ask your health insurance company whether your policy applies overseas and whether it will cover trips to a foreign hospital. If not, there are many companies that offer short-term travel health insurance for a reasonable fee. A list can be found on the US State Department's travel website. Ks5u Pack well. Dr. Poumerol also suggests bringing a note from your doctor in English and the language of the country you're visiting. Packing an emergency contact list is important. Contacts should include the local embassy , s who should be informed if you get sick and your health insurance company. Be care. You have to be in charge of your health. If you're being treated abroad, question the medical staff about their sterilization practices; injection equipment should be put in boiling water for at least 30 minutes or used only once. Also be sure that doctors and nurses are wearing gloves to prevent fluid transfer. Limiting your alcohol intake will keep you focused on your safety. If your common sense is perfect, the rest of your body should follow. What is the best title for this passage?

Back those photos up The images were striking. Homes on the East Coast were washed away by Superstorm Sandy. People were in tears, picking up faded photographs, among their only remaining possessions. If that doesn't move you to get serious about safekeeping your lifetime of memories, what will? The digital age offers tools never imaginable before--including one-click access to a lifetime of family photos. Here is a brochure on how to back up your photos and save them online, where they can live forever and be accessible in good times and bad. Scanning The first step for those old photos is to scan them and save them to a digital format. Most printers come with scanners these days, so that's an easy but extremely time-consuming step. Storing the photos With your scans in place, import the photos into your computer, and back them up. You could make multiple copies of the disks and spread them to loved ones. Or you could choose external hard drives or USB thumb drive, and add your photo and video collection from your computer. Online backup If you need lots of space, look at a pure online backup service, Caronite. Caronite backs up 300 million files daily. Once you sign up, it starts to pick up everything you have on your hard drive. But photo collection on your computer's main hard drive charges for $59 a year. Cloud Storage For folks who don't need automatic backup, but instead want to take a more active approach, Dropbox, Google Drive and Microsoft's SkyDrive let you store files online by yourself, share and instantly access them. All offer free options--2GB of free storage for Dropbox, 5GB for Google and 7GB for SkyDrive. But if you want more, you need to pay. Bottom Line The hard drive or flash drive is the cheapest and easiest. But drives can fail. Online services are more expensive, but more secure. With more of us switching back and forth between our computers, such services are the best way to get access to our data from wherever we are. Which of the following allows storing files automatically?

Sunscreens can offer protection from two types of ultraviolet (UV) rays : UVB, which according to the Skin Cancer Foundation, are the chief cause of sunburn and play a key role in the development of skin cancer, and UVA, which get through the skin more deeply and are largely responsible for skin aging and wrinkling, as well as skin cancer risk. The SPF measurement on sunscreens refers to the UVB protection level -- and the number may not mean what you think it does. SPF 15 doesn't protect you from 15% of UVB rays, just as SPF 100 doesn't protect you from 100% of the rays. In fact, as you get into the higher numbered SPF sunscreens (think: 50 and above), the difference in UVB protection is actually pretty small. Theoretically, though the increase in UVB protection with a super-high SPF sunscreen may be not worth considering, it may help, and certainly can't hurt, to use it -- that is, as long as you do so correctly. "The only _ is whether you're giving yourself a sense of false security," Dr. Gohara says. Indeed, as Dr. Wang also pointed out, when people choose increased SPFs, they may actually feel so protected by the product that they finally ignore proper sun protection. "When people use really high SPF products, they tend not to reuse, they tend to stay out in the sun much longer, and they don't use other protective measures such as clothing and hats," he says. Regardless of any increase in protection that a high SPF may or may not offer, one thing is certain: It doesn't give your body a free pass from sunburns, aging, or cancers, and it doesn't protect you from those things for any greater length of time than the lower SPF options. Both Dr. Wang and Dr. Gohara emphasized that, no matter what the SPF is, it's important to reapply your sunscreen every two hours. Why are we advised to reapply our sunscreen every two hours?
|
[
"We choose too low SPF products.",
"The higher SPF can make us stay outside longer.",
"Clothing and hats are not enough for sun protection.",
"It can't completely protect us from aging, sunburns or cancers."

Some problems are difficult to solve.But there are a lot of number expressions that can help.For example, if we put two and two together , we might com e up with the right answer.We know that two heads are better than one.It is always better to workwith another person to solve a problem.Some problems have only one solution.You cannot be of two minds over this.But with any luck , we can solve the problem in two shakes of a lamb' s tail.In other words, we could have our answers quickly and easily. Sometimes we can kill two birds with one stone.That is , we can complete two goals with only one effort or action.But we must remember that two wrongs don' t make a right.If someone does something bad to you, you should not do the same to him. If you are going out with your girlfriend , or boyfriend , but you don' t want another friend to go a long on your date, you can just say to your friend : two' s company , three' s a crowd. When I was a young child in school , I had to learn the three R' s.These important skills are reading , writing and arithmetic.These three words do not all start with the letter " R".But they have the sound of " R".My teacher used to give three cheers when I did well in maths.They gave praise and approval for a job well done. Some of my friends were confused and did not understand their school work.They were at sixes and sevens.In fact , they did not care if they finished high school.But they were happy when they completed their studies and graduated from high school.They were in seventh heaven.They were on cloud nine.Nine times out of ten students who do we'll in school find good jobs.Some work in an office doing the same things every day at nine-to-five jobs.You do not have to dress to the nines , or wear your best clothes , for this kind of work.

If you were asked what your body is made of, probably you would say that it is made of flesh and bones and covered with skin. You also know something about the blood which flows through it, and that there is a very important part which we call the brain. But the flesh and the bones make up the largest part of the body, and there is a good deal to be learned about them. You know the general appearance of both flesh and bone from the parts of animals which you see in the butcher's shop. Bone is hard, and of a white color; indeed, it looks more like a piece of wood or stone than a part of a living animal. But bone is a real part of the living body, and it grows and is nourished just as the body is. If a man breaks the bone of his arm or his leg, it is firmly bound up, to prevent the broken parts from moving out of the proper places, and in time then bone grows together again and becomes quite strong. The bones are fastened together by various kinds of joints . They form the framework of the body, and give it strength to retain its proper shape. This framework is called the skeleton . Some animals, such as worms and slugs, have no skeleton; and others, such as shellfish, have a kind of hard covering or skeleton outside. The most important part of the skeleton is the backbone. It is so important that naturalists divide all animals into two classes,--- those which have a backbone and those which have none. All the higher animals, including man, have a backbone, or vertebral column as it is called. They are therefore called vertebrate animals. The others are called invertebrate animals. Why should the bones bound up firmly if they were broken?

Train X departs from station A at 11 a.m. for station B, which is 180 km so far. Train Y departs from station B at 11 a.m. for station A. Train X travels at an average speed of 70 km/hr and does not stop anywhere until it arrives at station B. Train Y travels at an average speed of 50 km/hr, but has to stop for 15 min at station C, which is 60 km away from station B enroute to station A. Ignoring the lengths of the trains, what is the distance, to the nearest kilometre, from station A to the point where the trains cross each other?
|
[

] |
C
|
Explanation :
Total time taken by B to cover 60 km
60/50 hr i.e 6/5 hr.
It stops at station C for 1/4 hr
Now , in (6/5 + 1/4) hr , train X travels 70 x (29/20) = 101.5 km.
This means they do not cross each other by the time train Y finishes it stops at station C.
Let they meet after t hour.
Then, 70t + 50(t- 1/4) = 180.
t = 192.5/120 hr.
Distance from A will be 70 x 192.5/120 km i.e 112 km approximately.

[
"Gain of 5.5 %",
"Loss of 12.5 %",
"Loss of 10 %",
"Loss of 5.5 %"

B
|
Explanation:
Let C.P. of each apple be Re 1/-.
Therefore,
C.P. of 40 apples = Rs. 40
S.P. of 40 apples = Rs. 35
C.P. of 40 apples > S.P. of 40 apples
Loss = 40 – 35 = Rs. 5
Loss% = Loss/c.p. ×100
Loss% = 5/40 ×100
Loss% = 12.5%

Owls are some of the world's greatest hunters. From head to feet, owls' bodies are built to hunt. Scientists are studying all the things that make owls such great hunters. Most owls hunt at night. The birds have excellent hearing, which helps them find their next meal in the dark. Owls have one ear that is larger and set higher than the other. When an owl hears a sound, it listens closely. Is the sound lounder in its right ear or left ear? Does the upper or lower ear detect the sound first? The information helps the owl find the location of its prey without ever seeing it. Owls don't depend just on their hearing to hunt. After a sound draws an owl's attention, it zeroes in with sight. Many birds have eyes on either side of their heads. But an owl's eyes face forward, like a person's. Images from each eye combine to form a 3-D picture, similar to how we see. That helps owls better judge a prey's size, distance, and speed. An owl's eyes are so large that they can gather lots of light. That helps the owl see better when hunting at night. An owl's eyes are also fixed in their sockets . It can't roll them like we can. Instead, an owl keeps prey in its sight by turning its head. Owls can move their beads nearly upside down and turn them 270 degrees around. Their necks have 14 vertebrae . That's twice as many neck bones as a person has. The blood vessels thread through holes in an owl's vertebrae. The researchers found that these holes are very large so that the extra space provides an air cushion that protects the vessels. Detecting prey is only the first step for owls. Next they must catch their meals. An owl can fly inches over your head and you can't hear anything. The secret to owls' silent flight is their feathers. Fine "hairs" cover the surface of an owl's wing feathers. And the feathers' edges have soft barbs . Together, they make the sound of air rushing over the owl's wings quieter and less clear. According to text, an owl's eyes _ .

Animals do many different, amazing things to get through the winter. Some of them migrate .Many birds migrate in autumn. Because the trip can be dangerous, some travel in large groups. For example, geese fly in noisy, "V"-shaped groups. Other kinds of birds fly alone. Some animals stay active in winter. They must change themselves as weather changes. For example, a kind of rabbits grow white fur to help them hide in the snow. It's hard to find food in winter for animals. Some animals, like mice, collect lots of food in autumn. Some animals eat different kinds of food as the seasons change. The red fox eats fruit and insects in spring, summer and autumn. In winter, it cannot find these things, so it eats small animals instead. Some animals hibernate for part or all of the winter. This is a special, very deep sleep. The animal uses very little energy. In autumn, these animals get ready for winter by eating much more food than in summer and storing it as body fat. Squirrels store food like nuts to eat later in winter. Bears and some bats hibernate.

For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive to such messages. Scientists are using powerful radio telescopes to listen to signals from about 1, 000 stars, all within 100 light years of earth. In addition, they will scan the entire sky to "listen" for radio messages from more distant stars. Using a computer, they will be able to _ more than eight channels at one time. Scientists are looking for any signal they stands out from the background noise. Of the 200 billion stars in the Milky Way galaxy, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution of life. Based on the inhabitable(that can be lived in)planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life. However, many scientists wonder whether intelligent life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely. Other scientists believe that our search hasn't been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time, some scientists think it is likely that civilization much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.[ According to the passage, how many planets in our galaxy might be inhabitable?

When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky. "What excited me most was whether there were planets in other solar systems where life might exist," he says. "I decided to try to find planets orbiting other stars like our Sun." And he did. "My fellow researcher, Paul Butler, and I found our first planet in 1995," Dr. Marcy says. "We worked for ten years without finding anything! _ and our patience paid off." Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first "family" of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri. At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun. Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter. "Because it's so big, Jupiter pulls comets and asteroids , or they all come and hit the Earth." Dr. Marcy explains. "Without Jupiter , life on Earth would likely have been destroyed." A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, "We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!" Which of the following is true of the recent discovery?

"The planet is not as protective as Jupiter.",

Explanation:
Suppose they meet x hrs after 8 a.m
then,
[Distance moved by first in x hrs] + [Distance moved by second in (x - 1) hrs] = 330.
Therefore, 60x + 75(x - 1) = 330.

6 June, Saturday I read an article about people living in e-age yesterday. It talks about different ways of communicating like chatting on line, sending e-mails, sending different kinds of messages and keeping an online diary. The article says that people nowadays send e-mails at least once a day. I don't agree with this because I send e-mail only twice a week. However, I do check my e-mail once a day. I like receiving e-mails. About chatting online, the article says that chatting on line is becoming more and more popular among teenagers. I think this is true. Whenever I arrive at home, I turn on my computer and log on to chat online with my friends. I prefer chatting online to calling a friend, because I can chat with many friends at the same time. But I like using mobile phones. When I do not have my computer with me I can send short massages to my friends. I also like keeping in touch with them in this way. I keep an online diary four times a week. I like telling others what has happened to me. I think I am one of the people living in the e-age. I can live without computers or mobile phones.

As more people use smart phones to pay bills and store personal information, strict password security has become more important than ever. A new study shows that free - form gestures - sweeping fingers in shapes across the screen of a smart phone--can be used to unlock phones. These gestures are less likely to be observed and reproduced by others than traditional typed passwords. "All that it takes to steal a password is a quick eye," said one of the researchers of the study. "With all the personal information we have on our phones today, improving their security is becoming increasingly necessary." In developing a secure solution to this problem, the researchers studied the practicality of using free - form gestures. With the ability to create any shape in any size and location on the screen, the gestures were popular as passwords. Since users create them without following a template, the researchers predicted these gestures would allow for greater complexity. The researchers carried out a create - test - retest experiment where 63 people were asked to create a gesture, recall it, and recall it again 10 days later. The gestures were captured on a recognizer system designed by the team. Using this data, they tested the complexity and accuracy of each gesture using information theory. The result of their analysis is that people are favorable to use free - form gestures as passwords. To put their analysis into practice, the researchers then had seven students in computer science and engineering, each with considerable experience with touchscreens , attempt to steal a free - form gesture password by observing a phone user secretly. None of them were able to copy the gestures with enough accuracy. The gestures appear to be extremely powerful against attacks. Though the testing is in its early stage and widespread adaptation of this technology is not yet clear, the research team plans to continue to analyze the security and management of free - form passwords in the future. They believe this is the first study to explore free - form gestures as passwords. They will soon publish their findings. The main purpose of the text is to _ .

Do you know why different animals or pests have their special colors? Colors in them seem to be mainly used to protect themselves. Some birds like eating locusts , but birds cannot easily catch them. Why? It is because locusts change their colors with the change of the colors of crops. When crops are green, locusts look green. But as the harvest time comes, locusts change into the same brown color as crops have. Some other pests whose colors are different form plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night. If you study the animals' life, you'll find the main use of colors is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters because their colors are much like the trees. Colors are useful not only on the land, but also in the sea. A kind of fish in the sea can give out a kind of black liquid when the fish face danger. The liquid spreads over quickly, so they cannot be found by their enemies and can quickly swim away. That is why they live safely though they are not strong at all.

There is no excuse for not doing yourassignments . If you can't come to school, you should call your teacher or your classmate and ask about homework. It is yourresponsibility to find out what homework you have missed. It is not the teacher's job to remind you of the missed assignments. You must not be absent on a test day. If you are seriously ill, call and let the teacher know you will not be there for the test. If your teacher allows amake-up test ,you should take the test within one or two days after you return to class. Serious illness is the only reason for missing a test. Be on time! It is impolite to be late. Also, it bothers other students. If you must come in late, be sure to do it quietly. Have your books and papers out of your bag before you come into the room. Then go to your seat and sit down quietly. In the USA, it is not necessary to knock before you enter the classroom. Most teachers will give you a low grade if you are often late. In America, you should call your teacher by his or her last name instead of " teacher". Also you should use Mr, Miss, Ms or Mrs before the last name ( such as Mrs Smith or Mr Jones). This is polite. The teacher will tell you the title that he or she likes. It is impolite in the USA to eat, drink or chew gum during class. Don't do these until the break.

At 6:00 it'll chime 6 times. If we assume that the time taken to chime is x, then time between chimes is also x. So you have 6 chimes, which is 6x and 5 time intervals between chimes. This means that 11x = 55 seconds. Thus x = 5 seconds.
By a similar logic, at 12:00, there are 12 chimes and 11 intervals so the total time is (12+11)x = 23x = 115 seconds.

Exercise and Stretching When exercising, it is important to first warm up the muscles. Stretching pulls on the muscle fibers and it also results in an increased blood flow to the muscles being worked. Without a proper warm-up, it is possible that you may either damage some of the muscle fibers or pull a tendon. A pulled tendon, regardless of location, results in pain, swelling, and diminished function; if it is moderate to severe, the injury could immobilize you for an extended period. Recall the discussion about muscles crossing joints to create movement. Most of the joints you use during exercise are synovial joints, which have synovial fluid in the joint space between two bones. Exercise and stretching may also have a beneficial effect on synovial joints. Synovial fluid is a thin, but viscous film with the consistency of egg whites. When you first get up and start moving, your joints feel stiff for a number of reasons. After proper stretching and warm-up, the synovial fluid may become less viscous, allowing for better joint function.

Many people travel to different places in the world by air. Usually it takes a long time, perhaps half a day, for passengers to stay in the plan. So airlines offer passengers food. But it is common that they feel bad about food taste. Do you agree? To solve this problem, airlines try hard to improve their food. They would like to do so because they don't want to lose customers. However, according to scientific research, part of the reason why plane food tastes bad is that at high altitude we can not taste things as well as we do on the ground. Also scientists have found that our noses become very dry even before a plane takes off. As the plane moves up, the change in air pressure reduces one third of the sensibility of our taste buds . So our taste buds become senseless. The sad face, however, is that our noses don't know it. All of these help explain why food on the plane tastes so bad. They also help explain why airlines choose to offer passengers salty and spicy food. Without doing so, the food would be tasteless. Now there are many researches on this. According to one of them, some volunteers are asked to lie with their feet higher than their heads for weeks. And scientists write down their feelings about food taste. Though scientists try their best, it is not as easy as they thought. Because they can't deal with the special environment successfully, such as the change in air pressure, making food taste good is still hard for them. Why do scientists feel it hard to made food on the plane taste good?

There are lots of dangerous and terrible insects in Northeastern India, but the tree-bees are the most terrible. They are killers. Unlike most bees which will sting you only if they are disturbed , tree-bees will attack you in thousands for no reason. And they will chase you for your life. Walking along a dusty road while I was on holiday there last year. I found myself, without the least warning, the centre of such an attack. The air above me suddenly became thick with bees. Though it was hot, I went cold all over. Until then I had never heard of Indian tree-bees, but I had recently seen a film called "The Angry Swarm", which was about killer-bees. I began running to the village about half a mile away, but I was soon covered from head to foot with bees. I drove them away with my hands, only to make room for others. Each time I opened my mouth for breath, more bees entered my mouth, until it was stung to twice its usual size and I could hardly breathe. When I reached the village, I found some workers building a house. I ran towards them for help. But as soon as the workers saw the bees with me, they ran for safety at top speed. Soon my eyes had completely closed. I fell into a pile of brick dust. I pushed myself wildly down into it until my head and shoulders were covered. And then I tried hard to get out of the dust, the angry bees made a new attack on me. I was tired out and ran weakly about in circles. Soon I lost my consciousness . Later I learned that two quick-minded villagers ran to a pile of dry grass and quickly surrounded me with a thick wall of fire and smoke until the bees were driven away. They stayed with me, taking stings out of my body for the next three hours until a doctor came and gave me further treatment. Which of the following is NOT true according to the passage?

Elephants are the only species on the earth known to have death ritual besides man. They show a strong interest in the bones of their own kind.They are often seen gently touching the bones with their trunks and feet while remaining very quiet.Sometimes elephants completely unrelated to the dead will still visit their graves. Elephant researcher Meredith recalls something in his book about a typical elephant death ritual.The entire family of a dead elephant,including her young baby,were all gently touching her body with their trunks,trying to lift her. The elephant herd were all rumbling :The baby elephant was even observed to be weeping and made sounds that sounded like a scream,but then the entire herd fell incredibly silent.Then they began to throw leaves and dirt over the body and broke off tree branches to cover her.They spent the next two days quietly standing over her body.They sometimes had to leave to get water or food,but they would always return. Events of elephants behaving this way around human beings are common throughout Africa. On many occasions,they have buried dead or sleeping humans or helped them when they are hurt. An old woman fell asleep under a tree.When she woke up,there was an elephant standing over her,gently touching her.She kept very still because she was frightened.As other elephants arrived,they began to scream loudly and buried her under branches.She was found the next morning by the local people,unharmed. George Adamson also recalls when he shot all elephant from a herd that kept breaking into the farmers'gardens.George gave the:elephant's meat to 1ocal men and then dragged the rest of the body miles away.That night,the other elephants found the body,took the leg bones,returned them to the exact spot the elephant was killed,and made the death ritual.

Cutting down on the use of chemical fertilizers is one way to prevent dead zones in bodies of water. Preserving wetlands is also important. Wetlands are habitats such as swamps, marshes, and bogs where the ground is soggy or covered with water much of the year. Wetlands slow down and filter runoff before it reaches bodies of water. Wetlands also provide breeding grounds for many different species of organisms.

Everywhere man is altering the balance of nature.He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously.He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization.He exterminates some species on a large scale, but favours the multiplication of others.In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million. Many of these changes which he has brought about have had unforeseen consequences.Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers' wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece? These are spectacular examples; but examples on a smaller scale are everywhere to be found.We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested.We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes.We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock.

Up to 90% of school leavers in major Asian cities are suffering from myopia ---short-sightedness, a study suggests. Researchers say the "extraordinary rise" in the problem is being caused by students working very hard in school and missing out on outdoor light. Eye experts say that you are short-sighted if your vision is blurred beyond 2m. It is often caused by an elongation of the eyeball that happens when people are young. According to the research, the problem is being caused by a combination of factors - a commitment to education and lack of outdoor light. Professor Morgan who led this study argues that many children in South East Asia spend long hours studying at school and doing their homework. This in itself puts pressure on the eyes, but exposure to between two and three hours of daylight helps maintain healthy eyes. Cultural factors also seem to play a part. Across many parts of South East Asia, children often have a lunchtime nap. According to Professor Morgan they are missing out on natural light to prevent short-sightedness. A big concern is the numbers of the students suffering from "high" myopia. One in five of these students could experience severe visual impairment and even blindness. These people are at considerable risk--sometimes people are not told about it and are just given more powerful glasses--they need to be warned about the risk and given some self-testing measures so they can get to an ophthalmologist and get some help. For decades, researchers believed there was a strong genetic component to the condition. But this study strongly suggests an alternative view. "Any type of simple genetic explanation just doesn't fit with that speed of change; gene pools just don't change in two generations. Whether it's a purely environmental effect or an environmental effect playing a sensitive genome, it really doesn't matter, the thing that's changed is not the gene pool---it's the environment." As is mentioned above, which factor mainly results in students' myopia in South East Asia?

"Genetic faults of the people.",
"Elongation of the eyeball.",

Things Great and Small Nuclear Decay Helps Explain Earth’s Hot Interior A puzzle created by radioactive dating of rocks is resolved by radioactive heating of Earth’s interior. This intriguing story is another example of how small-scale physics can explain large-scale phenomena. Radioactive dating plays a role in determining the approximate age of the Earth. The oldest rocks on Earth solidified about 3.5×10 9 years ago—a number determined by uranium-238 dating. These rocks could only have solidified once the surface of the Earth had cooled sufficiently. The temperature of the Earth at formation can be estimated based on gravitational potential energy of the assemblage of pieces being converted to thermal energy. Using heat transfer concepts discussed in Thermodynamics it is then possible to calculate how long it would take for the surface to cool to rock9 9 formation temperatures. The result is about 10 years. The first rocks formed have been solid for 3.5×10 years, so that 9 the age of the Earth is approximately 4.5×10 years. There is a large body of other types of evidence (both Earth-bound and solar system characteristics are used) that supports this age. The puzzle is that, given its age and initial temperature, the center of the Earth should be much cooler than it is today (see Figure 31.26).

B

This is a question that is much easier than it first appears. If you work with the percents directly, you can solve it very quickly. If the man sells 32 apples for a dollar, he loses 40%. That means he is at 60% of his cost (100% - 40% = 60%). We are trying to figure out how many apples he has to sell in order to make a 20% profit, or be at 120% (100% + 20% = 120%). 120% is double 60%, meaning that we simply cut the number of apples in half to double our returns (from 60% to 120%), yielding 32/2 = 16 apples, or answer choice A.

In a unique research cooperation between Stratasys, Education, R&D departments and MIT's Self-Assembly Lab, a new process is being developed, known as 4D Printing. The 4D printing concept, which allows materials to "self-assemble " into 3D structures, was initially proposed by Massachusetts Institute of Technology faculty member Skylar Tibbits. Tibbits and his team combined a strand of plastic with a layer made out of "smart" material that could self-assemble in water. They advanced this concept by creating materials that can change into several different complicated shapes, though this kind of material remains the bottleneck of 4D technology. To many people that are just starting to get used to the idea of 3D printers, the name 4D is causing confusion because they cannot understand where this fourth "dimension" coming from. 4D technology shares many of the same principles of 3D printing and is essentially still about creating a new, 3D structure out of certain component; however, Tibbits states the fourth dimension at work here comes from concept of the fourth dimension of time. The difference between these 3D and 4D creations is that these new forms have the ability to transform and adapt over time. 4D printing works through self-assembly -- a system where "disordered elements form an "ordered" structure via an interaction. With these 4D printed materials, these disordered materials are strands or sheets of specially designed materials. Environmental changes then stimulate a response from them so that they form a preprogrammed shape. The idea of having adaptable technology that only relies on energy and non-human interactions raises some interesting questions about where 4D printing can be used and the practical applications in dangerous environments. This could mean improved infrastructures in extreme conditions, leading to a reduced need for workers to put themselves at risk, but the potential goes even further than that. The technology promises exciting new possibilities for a variety of applications. A solar panel or similar product could be produced in a flat shape onto which functional devices can be easily installed. It could then be changed to a compact shape for packing and shipping. After arriving at its destination, the product could be stimulated to form a different shape that serves its function. Also it could be used to build furniture, bikes, cars and even buildings. As with many of the ideas being put forward, it is easy to go a step too far into the extreme, but this just shows the potential of 4D in comparison to 3D. The next stage for the research is to move from printing single strands to sheets and eventually whole structures. And water need not be the process ' s only energy source. The major problem concerning the development of 4D printing lies in _ .

Why would an animal kill itself? It seems a strange question, and yet it is one that has made some scientists curious for a long time. For there is a kind of animal called lemming , that periodically killed themselves together, and no one knows just why! The small creatures which live in the Scandinavian mountains, feed on a diet of roots and special insects and live in nests they dig underground. When their food supply is large, the lemmings live a normal and undisturbed life. However, when the lemmings' food supply becomes too low to support the population, a _ migration begins. The lemmings leave their nests in groups. Great numbers of them begin to travel across the Scandinavian plains, a journey that may last weeks. The lemmings eat everything in their path, continuing their long march until they reach the sea. The reason for what follows remains unbelievable to naturalists. Upon reaching the coast, the lemmings do not stop but swim by the thousands into the sea. Most stay afloat only a short time before they tire, sink and drown. A common theory for this mass self-killing is that the lemmings do not realize that the ocean is such a huge body of water in their cross-country journey, the animals must cross many smaller bodies of water, such as rivers and small lakes. They may think that the sea is just another such swimmable path to go through. But no final answer has been found to the strange happening. Why are scientists curious about the lemmings' behavior?
|
[
"Because they are the only animals that live in Scandinavia.",
"Because it is very unusual for animals to kill themselves.",
"Because of the amount of food they can eat on their march to the sea.",
"Because they can gather together in such huge numbers."

D

In general, the process of interest is taking place in the system, and there are no changes in the composition of the surroundings. However, the temperature of the surroundings does generally change. Entropy changes in the surroundings are determined primarily by the flow of heat into or out of the system. In an exothermic process, heat flows into the surroundings, increasing the kinetic energy of the nearby particles. For an exothermic reaction, ΔS surr is positive. Conversely, heat flows from the surroundings into the system during an endothermic process, lowering the kinetic energy available to the surroundings and resulting in a negative value for ΔS surr .

In March 2004, Joe Ryan got a collection notice from a billing agency for Littleton Adventist Hospital near prefix = st1 /Denver,Colorado. The hospital wanted payment for surgery totaling $41,188. Ryan had never set foot in that hospital. Obviously there was some mistake. "I thought it was a joke," says Ryan. But when he called the billing agency, nobody laughed. Someone named Joe Ryan, using Ryan's Social Security number, had indeed been admitted for surgery. He figured clearing this up would take just a few phone calls. Two years later, Ryan continues to suffer from the damage to his credit rating and still doesn't know if his medical record has been cleared of wrong information. Joe Ryan was the victim of a little-known but frightening type of consumer fraud that is on the rise: medical identity theft, which involves using your name to get drugs, expensive medical treatment and even cheating insurance payments. As Ryan discovered, money isn't the half of it. When someone steals your name to receive health care, his medical history becomes part of your record -- and setting the record straight can be extremely difficult. That's because, in part, the information is distributed among dozens of caregivers, from doctors to medicine stores to insurance companies and labs. "I wanted to help straighten this out," says Ryan, "so I went to the hospital, and they had a three-inch-thick record for me, but they wouldn't let me see it. I showed them my ID, and they said that's not Joe Ryan's signature. Well, of course not! They had this other guy's signature." Ryan had fallen into a victim's Catch-22: If your record doesn't appear to be yours, you may not have the right to see it, much less change it. Ryan's next step was a visit to the Police Department. But the cops concluded there was not much they could do; local law enforcement has little experience with medical ID theft, and cases can end up being considered a civil matter.

It took Yang Liwei and his spaceship about 21 hours to circle the earth 14 times. Yang Liwei is China's first astronaut. He comes from Liaoning Province, and he has been an air force pilot since 1983. He was chosen from 14 pilots after many difficult tests. The life of an astronaut is hard to imagine for many people. To put on a space suit takes 15 minutes with the help of others. Sleeping in space is not easy, either. He has to sleep in a special sleeping bag on the wall because there is no gravity. Yang can eat chicken and rice. It's especially made to eat in space but it doesn't taste nice. "I'm feeling very good in space, and it looks wonderful here," said Yang, "I have looked at our beautiful earth and I have recorded all that I have seen here." China has become the third country in the world to send a person into space after the former Soviet Union and the United States. China is now planning its next launch.
