Sunstroke (中暑) is a condition that can quickly go from dangerous to deadly, especially if proper care isn't given immediately.

    Sunstroke, sometimes called heatstroke, is a result of the body temperature rising above safe limits. This causes the body's necessary functions to stop working.

    It's usually pretty easy to avoid sunstroke, as long as proper action is taken. In that case, you need to act as quickly as possible to return that person's body to a safe temperature. Here are a few tips to help treat sunstroke.

Call for help

    Call to get an ambulance as quickly as possible. This should be the first thing you do, especially if the sunstroke person has fainted(昏倒). Also, call for help from anyone nearby if you're in a public place. If there's no one around, call someone nearby if they can get there sooner than an ambulance. Ask everyone to bring you as much water as possible, if there isn't much nearby.

Get the person to a cooler area

    If there's a building nearby, aim for that. Anywhere with plenty of air conditionings and water is perfect. If a building isn't available, bring the person to a well shaded area.

Get the water flowing

    If the person is still conscious, get him or her to drink water. If there's a bathtub available，fill it with cool water and put the person in it.

If your water supply is limited, you have to save it. Dampen a towel or shirt and put it on the person's body. Focus on the face, neck，and chest.

Fan the person

    Getting moving air over the person cools him or her down. Use anything, a towel or sheet, a shirt your hands，or a piece of board. This is where having many people around really helps, as they can combine to fan the entire body.

    It seems that technology could be changing the places where we live. A project conducted by Johann Siau, a senior lecturer at the University of Hertfordshire's School of Engineering and Technology, has built on the university's InterHome project aimed to create a home that supervises people living at home who are weak or elderly.

    “We've developed a wristband type of device（装罝）,” said Johann Siau, “which allows us to monitor the condition of an elderly person, or whoever is wearing the device. It allows us to collect data of a person to see if the person has fallen or is away from where they are supposed to be. It connects an elderly person with an assisted living type of device with the InterHome.” The assisted living project is part of the university's wider InterHome project, which is the development of a smart house. The house stores the usage patterns of the person living there and can adapt to make it use as little energy as possible. Connecting the two together and building the service element（元素）allow us to introduce the assisted living idea to care for the elderly. It's very important that these technologies are there to help and support rather than to replace any of the existing services.

    The InterHome is not just a prototype（样品）or a vehicle for research. It's a study tool to help students from different scientific backgrounds learn about and develop technology. The InterHome combines the latest broadband technology, mobile data and communication. Researchers and students make sure that all the technology works together. Students get experience by developing new hardware and software themselves. It requires a variety of skills from students—electronic engineers, computer students, design students and so on. “The present plan we are working on is a smart home project in Watford with some commercial companies, ” said Johann Siau. “We are looking at how a smarter home can provide extra value services.”

    A court battle between German and Israeli archives （档案馆） over Kafka's manuscripts （手稿）raised literary, not just legal, questions. At the time of his death, Kafka hardly seemed like a candidate for world fame. He had a minor reputation in German literary circles. He published a few stories in magazines, but they received little attention.

    After he died in 1924, his friend Max Brod collected, edited and published his works - despite Kafka's own instructions in his will ordering the manuscripts to be destroyed - thus making Kafka a household name after his death. When the Nazis invaded Prague, Brod escaped to Israel, bringing the manuscripts with him. When he died in 1968, his manuscripts, together with those of Kafka, were transferred to his secretary Esther Hoffe.

    Even though Brod asked in his will that the manuscripts be given to a public archive, Hoffe sold some of them abroad for a great deal of money. Many of them eventually made it to the German Literature Archive. In 2007, she died and left her properties to her daughters. Then the case about the manuscripts started after the death of one of her daughters. The court said Hoffe had no rights, and could not have any such rights for the documents Brod took from Kafka's apartment after his death.

    Ironically, Kafka's stubborn homelessness and non-belonging in his works were accurately what ensured his place at the center of 20^th-century literature. W. H. Auden proposed that Kafka was to the cold, absurd 20^th century what Dante or Shakespeare had been to their times - the writer who captured the spirit of the age. That is why, in the end, it hardly matters whether Kafka's manuscripts stay in Germany or Israel. What counts is that we are all living in Kafka's world.

    Dark Sky Parks around the World

    Warrumbungle National Park

    Situated in the central west slopes of New South Wales is Australia's only dark sky park, Warrumbungle. The park has served as a dark sky park since July 2016. Its crystal-clear night skies and high altitude make it a natural, educational, and astronomical heritage site in the southern half of the earth. Tourists can use Australia's largest optical telescope within the park boundaries to view the auroras(极光)，the Milky Way, and faint shooting stars.

    Sark

    Sark is a Channel Island near the coast of Normandy under the protection of the UK. It was the World's First Dark Sky Island set up in January 2011. Its historical and cultural blend attracts over 40,000 tourists annually. With no motor vehicles and public lighting on the island, there is an exceptional view of the dark skies. A rich Milky Way is visible in the dark night skies from the shores of the island.

    Pic du Midi de Bigorre

    Pic du Midi de Bigorre in France was designated as a dark sky park in December 2013 making it the second largest dark sky park in the world. The park covers 3.112 square kilometers spread across the Pyrenees National Park and UNESCO's World Heritage site, Pyrenees-Mont Perdu. The park attracts over one hundred star watchers every year. The Observatory Midi-Pyrenees, which was built in 1870, is one of the world's highest museums at a height of 2,877 meters above sea level.

    Ramon Crater/Makhtesh Ramon

    Ramon Crater is a unique 1,100-square-kilometer nature reserve located in the Negev Desert in Israel. In 2017, the Ramon Crater became the first designated dark sky park in the Middle East. Its location, rough climate, and forbidding landscape that are characteristic of the Negev have largely defeated historical attempts for human settlement, making it a great place to view the night skies. Stargazers usually camp in the desert to have an uninterrupted view of the stars, planets, and the Milky Way.

    Throughout much of human history, man has been the measure of many, if not all, things. Lengths were divided up into feet and smaller units from the human hand. Other measures were equally characteristic. Mediterranean traders for centuries used the weight of grains of wheat to define (定义) their units of mass. The Romans used libra, forerunner of the pound, by referring to the weight of a carob (角豆树) seed.

    The sizes of similarly named units could also differ. The king's foot, used in France for nearly

    1,000 years after its introduction by Charlemagne in around 790 AD, was, at 32.5cm,around a centimeter shorter than the Belgic foot, used in England until 1300.Greek,Egyptian and Babylonian versions of water in a fixed container varied from one another by a few kilos, Nor was there agreement on such things within countries. In France, where there was no unified (统一的) measurement system at the national level, the situation was particularly terrible. The lieue (former measure of distance), for example, varied from just over 3 km in the north to nearly 6 km in the south.

    Although John Wilkins, an Englishman, first put forward a decimal system (十进制) of measurement in 1668,it was the French who in 1799 made it law. The Système International d'Unités (SI, or the metric system, as it is better known) developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States. Now the International Bureau of Weights and Measures in Paris is set to give the metric system its biggest shake-up yet.

    At a meeting in Versailles, France, on November 16th,2018,the world's measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常数).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20^th 2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.

Scholars in quest of demystifying the enigmatic depths of the subaquatic cosmos have been bestowed with a trove of invaluable data, courtesy of a conglomerate of international experts who have compiled a compendium delineating the fauna that emit or are anticipated to emit acoustic waves beneath the waterline.

Under the aegis of Audrey Looby, a luminary from the University of Florida, the Global Library of Underwater Biological Sounds consortium, in unison with the World Register of Marine Species, has meticulously chronicled 729 species of marine mammals, aquatic vertebrates, and invertebrates that generate either active or passive auditory signals. Furthermore, the register encompasses an additional 21,911 species presumed to be potential sources of sound.

"Given that the aquatic expanse envelops more than 70% of the Earth's terrestrial envelope, the majority of our planet's ecosystems are submerged, and it is a prevalent misconception that the majority of these aquatic entities exist in an auditory vacuum. The recently unveiled exhaustive digital repository, which catalogues the known sound-producing creatures, is unprecedented and has the potential to transform the domains of marine and aquatic science," elucidated the team of investigators.

"The act of eavesdropping on the subaquatic symphony can unveil a plethora of insights regarding the species that orchestrate these sounds and serves a multitude of applications, from the stewardship of fisheries, the detection of invasive species, to the appraisal of the imprint of human activity on the environment," remarked Looby, who is also the co-architect of FishSounds, a repository that curates a spectrum of research records on the acoustic emissions of fish.

The research of this collective was disseminated in the annals of Scientific Data and featured contributions from 19 scribes hailing from six distinct nations. "Comprehending the modalities of interaction between marine species and their environs is of paramount global significance, and the unrestricted availability of this dataset marks a monumental stride towards this aspiration," proclaimed Keran Cox, an affiliate of the investigative cadre.

"The majority of individuals are acquainted with the vocalizations of cetaceans or marine mammals, yet are frequently astonished to discover that a multitude of fish and invertebrates also utilize sound as a medium of communication," Looby stated. "Our database serves to exemplify the ubiquity of sound production in the subaquatic realm across a diverse array of creatures, yet our understanding remains in its infancy, with much yet to be uncovered."
