【推荐1】Our Library uses the Dewey Decimal Classification system(Dewey for short) to arrange books and other resources on the shelves so you can locate them easily. We’re going to show you how to use Dewey to find a book at any Library site.

Once you’ve searched for your item on Library Search, you’ll see something like this:

Globalization and education: critical perspectives Nicholas C Burbules; Carlos Alberto Torres 2000; ISBN0415920485(hbk); ISBNO41520477(pbk); ISBN97804 15920483; ISBN9780415920476 ◆Available at Main Library Blue Area Floor 1(370. 193 B174) Find in Library     Details       Reviews and tags

The part in the brackets is the bit we’re interested in. What do these numbers next to the book’s location mean? The numbers shown are a “shelfmark”. You’ll find one of these on every book in the Library—a lot of customers find this confusing at first but if you break down the information into three sections, it’s easier to understand.

1. The numbers in front of the decimal point indicate the subject area(in this case 370). Look for this number first.

2. Next, look for the number after the decimal point(in this case 193).

3. Now look for the letter(s)and number(s). Letters are usually the initial letter(s)of the author’s name(in this case, Burbules).

Sometimes, you will see extra letters before the shelfmark. This shows that a book is part of a collection within the Library. For example: M. E. 279. 32R29 is part of the Middle Eastern collection. Find the collection first, before looking for the number.

【推荐3】Starting university can be a costly experience for most students. But thankfully, with a little know-how, you can gain the benefits of being a student with a lot more cash in your pocket than you would have expected.     1     Checking out these top money-saving tips might be helpful.

Save money on food.

Student life doesn’t have to be about empty cupboards and living off takeaways or ready meals.   In fact, it can be useful habit to compare the price.     2     One of the easiest and most efficient ways to do that is by using a price comparison site.

Use student transport discount.

We have a love-hate relationship with public transport.     3     Luckily, most cities have local bus operators that offer student’s passes, which are much cheaper that standard tickets.   These can usually be used at all times of the day, including peak travel times.

    4    

Going out to a nightclub can be expensive. So take full advantage of student offers, where drinks are cheap and entry is often free. Be sure to keep an eye out for any freebies and special student offers advertised at local restaurants, cinemas and high street shops.

Spend less on textbooks.

Before you rush out and spend your entire student loan on books, check your lecture outlines and figure out which books you really do need to own, and which ones you can just borrow from the library.    5     And you can also share the cost with your classmates.

【推荐1】At CES (Consumer Electronics Show) 2020, one of the more well-represented gadget (小器具) categories was definitely consumer robots—but none was more adorable than a new robot pet from industrial robot startup Elephant Robotics.

This robot pet is a fully autonomous companion that can respond to touch and voice—and even play with toys, and it's hard not to love the thing after spending even just a brief amount of time with it. Marscat's pedigree (血统) is a bit unusual, since Elephant Robotics is focused on building what's known as “cobots”, or industrial robots that are designed to work alongside humans in settings like factories or assembly (装配) plants.

Elephant Robotics, which was founded in 2016, already produces three lines of these cooperative robots and has sold them to customer companies around the world, including in Korea, the U. S. , Germany and more.

This new product is designed for the home, however, not the factory or the lab. Marscat is the startup's first consumer product, but it obviously benefits immensely from the company's expertise and experience in their industrial robotics business. Marscat walks, runs, sleeps, sits. stretches, bites nails and even buries litter although she won't produce any waste. It may express different emotions by different meows (喵) or gestures. Marscat is unique from its eyes，body to personality. It has six characters which can be changed. She may be energetic or lazy，social or shy. Her personality develops through the way the users pet her.

While Marscat provides that kind of functionality out of the box, it's also customizable and programmable by the user. Inside, it's powered by a Raspberry Pi, and it ships with Marscat SDK, which is an open software development library that allows you to fully control and program all of the rohat's functions. This makes it an interesting gadget for STEM (Science, technology. engineering, math) education and research, too.

【推荐2】Can you imagine digging in your yard one day and finding a life-sized soldier made completely of clay? That’s what happened several decades ago when farmers in Xi'an, China, were digging wells.

Archaeologists（考古学家） have since found about 6,000 more of these soldiers, along with horses, weapons, tools, and other artifacts. The huge army was meant to protect the tomb of the first ruler of China. The first emperor of China, Qin Shihuang, accomplished a huge amount during his rule. Between 221 and 210 B.C., he started the construction of the Great Wall. He built a large network of roads. He introduced a new writing system, currency（货币）, and a set of measurements. The emperor also ordered the construction of a huge army of life-sized terracotta soldiers. These, he hoped, would protect his tomb after his death.

The soldiers in Xi'an's terracotta museum are today light brown, but they weren't always. They began as an army of red, blue, yellow, green, white, and purple. Sadly, most of the colors did not last to the present day. After being exposed to air during excavation(挖掘), the coating under the paint began to fall off. The paint disappeared in less time than it takes to boil an egg, taking with it important pieces of history.

Now new techniques are starting to reveal the army's true colors. Archaeologists have recently discovered an area with more than a hundred soldiers. Many of these still have their painted features, including black hair, pink faces, and black or brown eyes. Chinese and German researchers have developed a special liquid to help preserve the soldiers’ colors. After they find a soldier or other artifacts(手工艺品), archaeologists spray it with the liquid. They then cover it in plastic. Archaeologists are also finding colors in the dirt around the soldiers. It’s important not to disturb the dirt, so the colors won’t be lost. “We are treating the earth as an artifact,”says archeologist Rong Bo, the museum’s leading chemist. The next challenge, says Rong, is to find a way to apply the colors to the army again. Once that happens, artists can bring Emperor Qin's army back to life in full, vivid color.

Mars Science City was originally scheduled to cover 176,000 square meters of desert-the size of more than 30 football fields-and cost approximately 135 million dollars. To create a space for Dubai's Mohammed Bin Rashid Space Centre (MBRSC) to develop the technology needed to colonize Mars,architects Bjarke Ingels Group were asked to design a prototype of a city suitable for sustaining life on Mars-and then adapt it for use in the Emirati desert.

For this unique commission,the architects first had to overcome the immense challenges of creating a design to make the severe environment of Mars habitable. Mars has a thin atmosphere and no global magnetic field,so there's little protection from harmful radiation. Temperature is another problem-the average on Mars is a chilly 63 degrees C. The thin atmosphere also means there's little air pressure,so liquids quickly evaporate into gas; despite freezing temperatures,an unprotected human's blood would boil on Mars.But according to Jonathan Eastwood,director of the Space Lab at Imperial College London,the biggest challenge in terms of a sustained presence on Mars is not the engineering or scientific challenge,but the human and personal one.More researches need to be done to test the effects of isolation on mental and physical health of astronauts.

The MBRSC hopes that,in future,such research could take place in Mars Science City.This is going to be our platform where we can develop the science and the technology that will help us in our future missions to Mars,said Adnan AlRais,Mars 27 Program Manager at MBRSC."We want to come up with a totally new facility that will help the international community.”
