A pilot cannot fly by sight alone. In many conditions, such as flying at night and landing in dense fog, a pilot must use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving. The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300,000 kilometres in one second. A radar set sends out a short burst of radio waves. Then it receives the echoes produced when the waves bounce off objects. By determining the tune it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects. The word "radar" in fact gets its name from the term "radio detection and ranging". "Ranging" is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots radar is essential for air traffic control tracking ships at sea, and for tracking weather Systems and storms.

 According to the passage, what can radar detect besides location of objects?

Although experts agree that traditional meetings are essential for making certain decisions and developing strategy, many employees view them as one of the most unnecessary parts of the workday. The result is not only hundreds of billions of wasted dollars, but the worsening of what psychologists call “meeting recovery syndrome”: time spent cooling off and regaining focus after a useless meeting.  It’s isn’t anything novel that workers feel fatigued after a meeting, but only in recent decades have scientists deemed the condition worthy of further investigation. Meeting recovery syndrome (MRS) is most easily understood as a slow replenishment of our limited mental resources. When an employee sits through an ineffective meeting their brain power is essentially being drained away, says Joseph A. Allen, a professor at the University of Utah. If they last too long, fail to engage employees or turn into lectures with little to no personal interactions, meetings will significantly diminish employees’ psychological stamina. Taking time to recover a must, but doing so comes at the expense of productivity.  As humans, when we transition from one task to another – such as from sitting in a meeting to doing normal work – it takes an effortful cognitive switch. We must make a big mental effort to stop the previous task and then expend significant mental energy to move on to the other. Some can bounce back from horrible meetings rather quickly, while others carry their fatigue until the end of the workday. It’s even worse when a worker has several meetings that are separated by only 30 minutes.  While no counter-MRS measures have been tested, Allen says one trick that might work is for employees to identify things or locations that quickly change their mood from negative to positive. As simple as it sounds, finding a personal happy place, going there and then coming straight back to work might be the key to reducing recovery time. Another solution is to ask ourselves if our meetings are even necessary in the first place. If all that’s on the agenda is a quickly catch-up, or some non-urgent information sharing, it may better for managers to send an e-mail to his or her subordinates instead. Most important, however, if for organizations to awaken to the concept of meetings being flexible, says Allen. We have to get rid of the acceptance of meetings as sites of pain, when they should be places of gain.” Allen says.

Thanks to electricity, candles are no longer a necessity in our lives, but they are still a pleasure. The warm flame of candlelight can quickly alter the mood and atmosphere of a room, often creating a  peaceful scene that electric light just cannot match.
Candles are an important part of many cultural and religious festival and have been burnt in various forms for centuries. The ancient Romans and Egyptians made candles from a type of fiber coated with wax. However, up until the nineteenth century, most candles were made from a substance called tallow, obtained from beef fat. Tallow candles were very smoky and, understandably, had an unpleasant odor.
In the 19th century, candle makers learned to separate stearin, the solid form fat used as a type of glue, from tallow and used it to harden other fats. Candles that contained stearin would burn longer than previous ones and had a better smell. Stearin is still one of the main components of modern candle- making, and the techniques used to create candles today are much the same as they have been for many years. These days, the increase range of wax dyes, perfumes and other additives that are now available make candle making a very exciting and rewarding hobby.
Sales of candles have increased greatly over the last few years, showing that they have become part of our lives again, not through necessity, but because of the magical atmosphere they create. In our increasingly stressful lives, the calming quality of candlelight has a relaxing effect that many enjoy.
For those would like to learn to make candles, finding and buying candle-making kits is easy. Candle- making is definitely enhanced by the exciting possibilities of experimentation with various materials. Be brave and try out different effects – some of the most wonderful creations can happen by accident. With a bit of practice, you will be amazed at the very professional finish that can be achieved.
Despite their delicate beauty, candles can, of course, be highly dangerous. One should never leave lit candles unattended, even for a few moments. Always make sure candles are securely placed within candleholders.
Teach your children to respect a burning candle, and of course keep burning candles away from flammable materials. Keep your home safe by remembering that a candle is magical, but fire can be very destructive. Be careful, and enjoy the beauty of your candles!

Globally we use more energy than ever before, and the demand is rapidly growing. Economic expansion of emerging market economies, population growth and our increasing use of energy-consuming devices are among the most important contributing factors. About one-third of the radiation hitting Earth’s atmosphere is reflected back out into space by clouds, ice, snow, sand and other reflective surfaces. The other two-thirds is absorbed by the Earth’s surface and the atmosphere. As the land, oceans and atmosphere heat up, they re-emit energy as infrared thermal radiation, which passes through the atmosphere. Heat-trapping gases like carbon dioxide (CO2) absorb this infrared radiation and prevent it from dissipating into space, giving rise to what we know as the greenhouse effect. The accumulation of CO2 and other greenhouse gases in the atmosphere is the dominating driver of recent climate change. CO2 is estimated to be responsible for 64 % of man-made global warming. Other greenhouse gases are released in much smaller amounts but still contribute significantly to the overall warming effect, as they are much more potent heat-trapping gases than CO2. The EU is taking action on many levels. One example is on fluorinated gases that are contributing less than CO2 but still a particular point of concern in addressing climate change. They are used in several types of products, such as in refrigeration, air-conditioning and heat pump equipment. While fluorinated gases are released into the atmosphere in smaller quantities than other greenhouse gases, they are extremely potent – they produce a warming effect 23 000 times greater than CO2. For this reason the EU has decided to control their use. The EU’s regulation on fluorinated greenhouse gases aims at cutting the Union’s emissions by two-thirds compared to 2014 levels. Chemicals are not only part of the problem – they are also part of the solution. Sustainable energy sources like solar power rely on chemical innovation using, for example, nanomaterials. One of the main challenges with renewable energy is how to increase its viability with the help of energy storage solutions. For example, solar panels have the best conditions in the desert, but that is not where most people live. Windmills also produce power during the night, which is when our energy consumption is at its lowest. In other words, technologies to improve energy storage and transportation is one of the important areas of research where innovation is needed

Gender inequality remains an everyday reality for the world’s women and girls. It can begin right at the moment of birth and continue throughout the course of a woman’s life. Despite critical advances over the course of recent history, women in all countries and across all socioeconomic levels in society can face various forms of unfair treatment, including discrimination, harassment, domestic violence and sexual abuse. Other forms of abuse that are particularly prevalent in certain countries or cultural contexts include forced marriage, honor killings, deprivation of education, denial of land and property rights, and lack of access to work and to health care. Women may experience human rights abuses at different points in their working lives, including during recruitment, hiring, promotion and termination processes, as well as in daily interactions with colleagues and supervisors. Outside of the workplace, women are often particularly vulnerable to the social and environmental impacts of business activities. For example, in many developing countries, women and girls are primarily responsible for fetching and hauling water. When company operations contaminate local sources, it is they  who carry the burden of walking, often for hours, to the nearest substitute, which can prevent them from working or going to school. According to the UN Entity for Gender Equality and the Empowerment of Women, gender “refers to the social attributes and opportunities associated with being male and female and the relationships between women and men and girls and boys, as well as the relations between women and those between men. These attributes, opportunities and relationships are socially constructed and are learned through socialization processes.” Furthermore, gender equality “refers to the equal rights, responsibilities and opportunities of women and men and girls and boys. Equality does not mean that women and men will become the same but that women’s and men’s rights, responsibilities and opportunities will not depend on whether they are born male or female.” Women and girls comprise half of the planet’s population; their empowerment is essential in expanding economic growth and promoting social development in a sustainable way. Evidence from around the world shows that gender equality advancements have a ripple effect on all areas of sustainable development, from reducing poverty, hunger and even carbon emissions to enhancing the health, well-being and education of entire families, communities and countries. In fact, “Equality between women and men is seen both as a human rights issue and as a precondition for, and indicator of, sustainable people-centered development.”

Read the following passage and choose the best answer (A, B, C, D):
Deforestation has important global consequences. Forests sequester carbon in the  form of wood and other biomass as the trees grow, taking up carbon dioxide from the atmosphere. When forests are burned, their carbon is returned to the atmosphere as carbon dioxide, a greenhouse gas that has the potential to alter global climate, and the trees are no longer present to sequester more carbon.  In addition, most of the planet’s valuable biodiversity is within forests, particularly tropical ones. Moist tropical forests such as the Amazon have the greatest concentrations of  animal and plant species of any terrestrial ecosystem; perhaps two-thirds of Earth’s species live only in these forests. As deforestation proceeds, it has the potential to cause the extinction of increasing numbers of these species.  On a more local scale, the effects of forest clearing, selective logging, and fires interact. Selective logging increases the flammability of the forest because it converts a closed, wetter forest into a more open, drier one. This leaves the forest vulnerable to the accidental movement of fires from cleared adjacent agricultural lands and to the killing effects of natural droughts. As wildfires, logging, and droughts continue, the forest can become progressively more open until all the trees are lost. Additionally, the burning of tropical forests is generally a seasonal phenomenon and can severely impact air quality. Record-breaking levels of air pollution have occurred in Southeast Asia as the result of burning for oil palm plantations.  In the tropics, much of the deforested land exists in the form of steep mountain hillsides. The combination of steep slopes, high rainfall, and the lack of tree roots to bind the soil can lead to disastrous landslides that destroy fields, homes, and human lives. With the significant exception of the forests destroyed for the oil palm industry, many of the humid forests that have been cleared are soon abandoned as croplands or only used for lowdensity grazing because the soils are extremely poor in nutrients. The vegetation that contains most of the nutrients is often burned, and the nutrients literally “go up in smoke” or are washed away in the next rain. Although forests may regrow after being cleared and then abandoned, this is not always the case, especially if the remaining forests are highly fragmented. Such habitat fragmentation isolates populations of plant and animal species from each other, making it difficult to reproduce without genetic bottlenecks, and the fragments may be too small to support large or territorial animals. Furthermore, deforested lands that are planted with commercially important trees lack biodiversity and do not serve as habitats for native plants
and animals, many of which are endangered species.

Money habits matter a lot in a relationship, even if you’re not married or living together, concludes Melissa A Curran, an associate professor at the University of Arizona, in a new study published in the Journal of Family and Economic Issues. That’s why she recommends being picky when it comes to dating. “Young adults should choose their romantic partner wisely,” Curran tells CNBC Make It. She and her colleagues assessed over 500 young twenty-somethings in committed relationships and had them rate their health and overall life satisfaction. She asked them questions related to their partners’ financial responsibility, such as, Do they spend within a budget? And, Do they usually pay off their credit cards in full? The researchers found that the more responsible the participants perceived their partners to be with money, the higher their own sense of well-being and the happier they were with their relationships. The opposite was also true. Participants who thought their partners were bad with money had a lower sense of well-being and felt less committed to the relationship. “This finding makes sense developmentally as the young adults are transitioning to adulthood,” says Curran. “It would make sense for them to draw upon romantic partners in terms of financial socialization agents.” By socialization agents, she means people who can teach and influence the participants on matters related to money. The idea is that the financial habits of whoever you’re dating can rub off on you. If your partner is bad with money, you might become bad with money too, which in turn affects your life overall, since the researchers also confirmed that your own financial habits definitely affect your well-being. For many young adults, parents are the most influential socialization agents. So, in this study, Curran also asked the participants about what their parents expected of them when it came to their finances. Did their parents, for example, expect them to track their spending? The researchers found that high expectations from an involved parent led the participants to perform better on a financial literacy test. But, unlike romantic partners, they did not seem to influence well-being. If you’re bothered by your significant other’s over-spending or general irresponsibility with money, Curran and her colleagues recommends talking things through. “Having discussions about finances and making financial decisions together helps couples become closer and more satisfied with their relationships.”

Read the following passage and choose the best answer (A, B, C, D):
Pollutants in the air aren’t always visible and come from many different sources. Smog hanging over cities is the most familiar and obvious form of air pollution. But there are different kinds of pollution - some visible, some invisible - that contribute to global warming. Generally any substance that people introduce into the atmosphere that has damaging effects on living things and the environment is considered air pollution. Carbon dioxide, a greenhouse gas, is the main pollutant that is warming Earth. Though living things emit carbon dioxide when they breathe, carbon dioxide is widely considered to be a pollutant when associated with cars, planes, power plants, and other human activities that involve the burning of fossil fuels such as gasoline and natural gas. In the past 150 years, such activities have pumped enough carbon dioxide into the atmosphere to raise its levels higher than they have been for hundreds of thousands of years. Other greenhouse gases include methane - which comes from such sources as swamps and gas emitted by livestock - and chlorofluorocarbons (CFCs), which were used in refrigerants and aerosol propellants until they were banned because of their deteriorating effect on Earth’s ozone layer. Another pollutant associated with climate change is sulfur dioxide, a component of smog. Sulfur dioxide and closely related chemicals are known primarily as a cause of acid rain. But they also reflect light when released in the atmosphere, which keeps sunlight out and causes Earth to cool. Volcanic eruptions can spew massive amounts of sulfur dioxide into the atmosphere, sometimes causing cooling that lasts for years. In fact, volcanoes used to be the main source of atmospheric sulfur dioxide; today people are. Industrialized countries have worked to reduce levels of sulfur dioxide, smog, and smoke in order to improve people’s health. But a result, not predicted until recently, is that the lower sulfur dioxide levels may actually make global warming worse. Just as sulfur dioxide from volcanoes can cool the planet by blocking sunlight, cutting the amount of the compound in the atmosphere lets more sunlight through, warming the Earth. This effect is exaggerated when elevated levels of other greenhouse gases in the atmosphere trap the additional heat.

Read the following passage and choose the best answer (A, B, C, D):
Where humans have planted crops for food, unless they are organic, poisonous chemicals have been sprayed on them; insecticides are used to kill insect pests and herbicides are used to kill weeds. Fungicides fight off fungal diseases. Artificial fertilizers are added to the soil to increase the yield of the crops. If these chemicals are used in excess, some of them dissolve in rainwater and drain into rivers, streams and ponds, polluting the water and killing the wildlife. The “weeds” competing with the farmers’ crops include wild flowers and many of these have become endangered through the use of herbicides. Insects rely on plants for food and breeding sites so the number of these are affected by a reduction in the number of plants. Many birds depend on insects for food so the numbers of birds may be affected by the use of both insecticides and herbicides. One of the reasons why the Barn Owl is endangered is due to a shortage of insects and it may also be poisoned by eating insects affected by chemical sprays. The case of DDT and other chemicals known as organo-chlorines is well known. These were first used extensively in the 1950s, sprayed onto crops to kill insect pests. Unfortunately, after a few years, it was noticed that birds of prey were rapidly declining in numbers and thousands of seed-eating birds were dying. By the 1960s, the once common sparrow hawk was a rare bird in Britain. The sparrow hawk’s prey was the seed-eating birds which were carrying the poisonous insecticides in their bodies. Consequently, many sparrow hawks and other birds of prey were being indirectly poisoned by the chemical sprays. The organo-chlorines also caused many birds to lay thin shelled eggs, which cracked easily. Research showed that the chemicals were entering the food chains and being stored in the fat of the animals’ bodies. For example, a thrush may eat snails which have eaten a sprayed cabbage plant. The thrush may not have eaten enough poison to be actually killed but a sparrowhawk eating several thrushes accumulates so much of the poison that it is killed. The chemicals become more concentrated as they travel up the food chain. Even most humans still have small amounts of organo-chlorines in their fatty tissues although these chemicals had been withdrawn from use by 1976. They are still used, however, in some Third World countries. By the 1980s, the sparrowhawk population had recovered dramatically and it is once again a common bird. This example shows just how dangerous the use of chemicals in the environment can be. As mentioned earlier, some plants are endangered through collectors such as the Venus fly-trap and some tropical orchids, but most threatened plants have become so through the destruction of their habitat. Once very common plants have almost disappeared because of the way humans have changed the land. For example, the Egyptian Papyrus, a type of reed, had been used for thousands of years for all sorts of things such as paper, medicine, boats, baskets, food etc. Then, when changes in the irrigation methods on the river Nile were introduced, this valuable plant almost completely disappeared. It was thought to be extinct until 1968 when a few plants were found in an undisturbed waterway. Orchids have been also collected from rainforests to become household favourites, causing many species to become endangered.

The field of 3-D printing comes with a new set of legal questions hospitals using the  technology will need to consider, said Bruce Kline, a technology licensing manager who oversees patents for new technology developed at Mayo Clinic. For starters, he said the STL file printers use are a lot like MP3 music files, in that they can be protected under copyright and require licensing to use. Copyright violations can occur if a purchased STL anatomical model file for rare disease is illegally shared with another institution that did not purchase the file from the vendor that created the file.  Under the law, if a device has a functional use it falls under patent law. If it is not functional, it falls under copyright law. Kline said most medical 3-D printing for educational models and complex anatomy evaluation currently falls under copyright. But, he said that will rapidly change in the coming years as customizable 3-D printable medical devices see wider use.  Additive manufacturing (AM) allows the creation of patient-specific devices at the point of care. Kline said an interesting fact is that these devices are FDA 510(k)-exempt if produced by a hospital instead of a medical device vendor. He said this blurs the lines between traditional vendor relationships, since the hospital can now become the manufacturer. However, if a hospital makes a device, it also becomes liable for it. He advised that it might be better for a commercial vendor to make the device for the hospital so the vendor assumes the liability of the device. Custom-made medical devices are also exempt under FDA regulations, Kline said. So, if a physician creates or modifies a device to meet the clinical needs of a specific patient’s anatomy, he said it is acceptable to use under current FDA rules. This may leave the door wide open for use of 3-D printed devices that are customized for each patient using their own 3-D imaging datasets.  It is possible printable device files may become available in the next few years to customize and print on demand. However, Kline said it will be much more difficult to enforce patents on these types of devices. He explained if someone makes one or two devices, there is no economical way for the creator of those device files to go after the user/maker of of unlicensed copies of the device to claim lost profits.
