Developed and developing nations can learn from each other seeking a low carbon economy, a Chinese government official said in Shanghai yesterday. “China doesn't lag developed nations in terms of energy saving and green economy”, said Zhou Changyi, director of the energy saving department of the Ministry of Industry and Information Technology.

    “While we can learn many aspects from developed nations, they also should learn something from us, such as water conservation,” Zhou said in a speech during the new Path of China's Industrialization forum at the ongoing China International Industry Fair 2009.

    He said industrialized nations and China are dealing with different issues to combat climate change. The United Kingdom, for example, is concerned about transport, buildings and new energy in reducing carbon emissions. For China, the most urgent task is how to realize new type of industrialization and avoid mistakes that other countries made when they industrialized.

    As such, overseas exhibitors at this year's fair are showing ways to help China achieve low carbon emissions in the industrial section.

    Swiss power and automation technology group ABB called for a stronger focus on product lifecycle assessment, or LCA, which is used to study the environmental impact of a product from the research and manufacturing stage through its usage and recycling.

    Tobias Becker, head of ABB's process automation division for North Asia and China, said LCA is an effective tool in helping manufacturing industries to reduce carbon emissions.

    LCA shows that industrial customers should focus on a product's environmental impact throughout its lifecycle instead of on its initial investment or ready to use stage. For example, a motor's initial investment accounts for only 3 percent of its lifecycle cost, while 94 percent goes to fuel consumption and the rest to maintenance.

    Richard Hausmann, North East Asia CEO of Siemens, said, “The color of future industrialization is green.”

    The Germany Company recently announces that it wants to receive orders worth more than 6 billion Euros (US 8.8 billion) for intelligent net power networks, Smart Grid, over the next five years. Siemens has set a 20 percent market share target for the global smart grid business.

    A smart grid delivers electricity from suppliers to consumers using digital technology, advanced sensors specialized computers that save energy, reduce costs and increase reliability. The United States and China are considered the two biggest markets for smart grid.

    The Chinese word "Shanzhai" means a small mountain village, but now it becomes an accepted name for fakes (假货), after "Shanzhai Cell-phones" produced by small workshops in southern China became popular in the mainland market over the past two years. Besides (除……之外，还有)"Shanzhai" electronic products, there are "Shanzhai" movies, "Shanzhai" stars and even a "Shanzhai" Spring Festival Gala, a copy of the 25-year-old traditional show presented by CCTV on Chinese Lunar New Year's Eve.

    "Shanzhai" has become a culture of its own, meaning anything that imitates something famous. In Chongqing, "Shanzhai" version "Bird's Nest（鸟巢）" and "Water Cube（水立方）" woven by farmers with bamboo attract(吸引) wide attention from tourists. Both are copies of the famous Olympic buildings in Beijing.

    A literature critic said that taking the "Shanzhai" Gala as an example, when the traditional CCTV program becomes less and less attractive to the audience, the "Shanzhai" version appears timely to attract people. "Although it is often connected with poor techniques and operation, 'Shanzhai' culture meets the psychological needs of common people and could be a comfort to their minds," he said.

    To the mainstream（主流） culture, the rise of "Shanzhai" culture is a challenge and a motivation（推动）. People believe different kinds of cultures developing together is a perfect way and it is for the public to choose.

    “Get your hands off me; I have been stolen,” the laptop, a portable computer, shouted. That is a new solution to laptop computer theft: a program that lets owners give their property a voice when it has been taken.

    The program allows users to display alerts on the missing computer's screen and even to set a spoken message. Tracking software for stolen laptops has been on the market for some time, but this is thought to be the first that allows owners to give the thief a piece of their mind.

    Owners must report their laptop missing by logging on to a website, which sends a message to the model: a red and yellow “lost or stolen” banner pops up on its screen when it is started. Under the latest version of the software, users can also send a spoken message.

    The message can be set to reappear every 30 seconds, no matter how many times the thief closes it. “One customer sent a message saying, 'You are being tracked. I am right at your door', said Carrie Hafeman, chief executive of the company which produces the program, Retriever.

    In the latest version, people can add a spoken message. For example, the laptop's speaker will say: “Help, this laptop is reported lost or stolen. If you are not my owner, please report me now.”

    The Retriever software package, which costs $29.95 but has a free trial period, has the functions of many security software programs. Owners can remotely switch to an alternative password if they fear that the thief has also got hold of the access details.

    If a thief accesses the Internet with the stolen laptop, Retriever will collect information on the Internet service provider in use, so that the police can be alerted to its location.

    Thousands of laptops are stolen every year from homes and offices, but with the use of laptops increasing, the number stolen while their owners are out and about has been rising sharply.

    Other security software allows users to erase data remotely or lock down the computer.

    Why we cry with happiness show: Responding with a negative reaction helps us deal with extreme joy. If you cry with happiness at weddings, you are responding to a happy experience with a negative reaction. The researchers believe the unusual reaction may help renew emotional balance in us and keep extreme emotions under control. The findings make it clear how people express and control their emotions, which could help improve their understanding of people's mental(精神的) health.

    Dr Oriana Aragon set out to explore the phrase “tears of joy”, which she said never made sense to her. But after studying a series of incongruous(不和谐的) expressions, she now understands better why people cry when they are happy. “People may be renewing emotional balance with these expressions,” she explained. “They seem to take place when people are struck by strong positive emotions. People, who do this, seem to recover better from those strong emotions.”

    The report show various examples of responding to a positive experience with a negative emotion, such as, a crying wife seeing the husband returning from war again, and teenage girls screaming at a Justin Bieber concert. Examples also include a baseball player who hits a home run, only to be slapped(拍) on the back by teammates, as well as when people cannot help kissing babies' faces who they consider lovely.

    Dr Aragon and her team discovered that people, who expressed negative reactions to positive news, were able to moderate(缓和) strong emotions more quickly. There is also some evidence that strong negative feelings may provoke positive expressions. For example, nervous laughter often happens when people are faced with a hard situation. We've seen people smiling during times of extreme sadness.

    “The findings affect our knowledge of how people express and control their emotions, which is importantly related to mental and physical health, the quality of relationships with others, and even how well people work together,” Dr Aragon said.

    We work with Cambridge County Council's Participation Team to create opportunities for young people to visit the University and learn more about it. The following events are scheduled for the 2019/2020 academic year.

    SuperStar workshops

    12 workshops are planned for young people aged 7 to 11. These half-day visits will be held throughout the year, at times when young people are not at school. If participants complete 8 of the 12 workshops, they will be awarded the nationally recognized SuperStar Crest Award.

    Please note, workshops will only run if we have a sufficient number of attendees (usually around 3+ participants).

    Explore University Days

    Explore University Days are for young people aged 12-15. Participants visit the University for two days and take part in a variety of university-related workshops, and other fun activities.

    Previous participants have joined in the following:

    • Visited the Sports Centre

    • Took part in a Neuroscience workshop

    • Enjoyed a two-course meal at a University College

    Dates will be confirmed in early December 2019, and a schedule for event will follow in the New Year.

    Events for post-16 students

    If you are studying for your post-16 qualifications and are considering applying for Cambridge or would like to find out more about a specific subject, the following events might be for you:

    • University and College Open Days

    • Subject Masterclasses

    • Cambridge Science Festival

    A headache is the feeling you get when your head hurts. Headaches can differ from very mild to incredibly powerful. They can last anywhere from 10 minutes to hours. Very bad headaches are called migraines. People who suffer from migraine headaches often need to take the day off from school or work and lie in bed all day.

    Why do people get headaches? There are many possible causes. People who drink too much caffeine (in coffee or soft drinks, for example) or alcohol can end up with headaches. This is because these kinds of drinks take water away from the body. If the brain doesn't have enough water, it gets smaller and pulls away from the head. This can be extremely painful. The best way to get rid of this kind of headache is just to drink lots of water.

    Tension headaches happen when the body's muscles are too tight. When people feel stress, it is common for the muscles near the head to become tense. Tension headaches might also be caused by not getting enough sleep. Some people suffer from tension headaches for only short times but for other people, these kinds of headaches are a chronic problem that happens again and again. A massage (按摩) might help to stop a tension headache. If that doesn't help, you might need to see a doctor.

    Headaches can also be caused by much bigger health problems. For example, a head or neck injury can cause them. Headaches can also be a warming sign of a heart attack.
