![]() Hence, there is the possibility that what appears to be entertainment may also be a means of achieving insight or intellectual growth.Īn important aspect of entertainment is the audience, which turns a private recreation or leisure activity into entertainment. This may be the case in various forms of ceremony, celebration, religious festival, or satire, for example. The experience of being entertained has come to be strongly associated with amusement, so that one common understanding of the idea is fun and laughter, although many entertainments have a serious purpose. Entertainment evolves and can be adapted to suit any scale, ranging from an individual who chooses private entertainment from a now enormous array of pre-recorded products, to a banquet adapted for two, to any size or type of party with appropriate music and dance, to performances intended for thousands, and even for a global audience. The process has been accelerated in modern times by an entertainment industry that records and sells entertainment products. Storytelling, music, drama, dance, and different kinds of performance exist in all cultures, were supported in royal courts, and developed into sophisticated forms over time, becoming available to all citizens. It can be an idea or a task, but it is more likely to be one of the activities or events that have developed over thousands of years specifically for the purpose of keeping an audience's attention.Īlthough people's attention is held by different things because individuals have different preferences, most forms of entertainment are recognisable and familiar.

Future work should explore the infectivity of aerosolized virus.This poem is a 曲 "qu" or song of the 元 Yuan Dynasty which is akin to 詞 "ci" or song of the 宋 Song Dynasty made up of long and short lines. Our results indicate that room ventilation, open space, sanitization of protective apparel, and proper use and disinfection of toilet areas can effectively limit the concentration of SARS-CoV-2 RNA in aerosols. Although we have not established the infectivity of the virus detected in these hospital areas, we propose that SARS-CoV-2 may have the potential to be transmitted through aerosols. We found that some medical staff areas initially had high concentrations of viral RNA with aerosol size distributions that showed peaks in the submicrometre and/or supermicrometre regions however, these levels were reduced to undetectable levels after implementation of rigorous sanitization procedures. Levels of airborne SARS-CoV-2 RNA in the most public areas was undetectable, except in two areas that were prone to crowding this increase was possibly due to individuals infected with SARS-CoV-2 in the crowd. The concentration of SARS-CoV-2 RNA in aerosols that was detected in isolation wards and ventilated patient rooms was very low, but it was higher in the toilet areas used by the patients. Here we investigated the aerodynamic nature of SARS-CoV-2 by measuring viral RNA in aerosols in different areas of two Wuhan hospitals during the outbreak of COVID-19 in February and March 2020. Although it is clear that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmitted through human respiratory droplets and direct contact, the potential for aerosol transmission is poorly understood 1-3. ongoing outbreak of coronavirus disease 2019 (COVID-19) has spread rapidly on a global scale. 10 State Key Laboratory of Virology, Modern Virology Research Center, College of Life Sciences, Wuhan University, Wuhan, P. 9 Shanghai Environmental Monitoring Center, Shanghai, P. 8 School of Public Health, Key Laboratory of Public Health Safety of the Ministry of Education and Key Laboratory of Health Technology Assessment of the Ministry of Health, Fudan University, Shanghai, P. 7 JC School of Public Health and Primary Care, The Chinese University of Hong Kong, Hong Kong, P.1 State Key Laboratory of Virology, Modern Virology Research Center, College of Life Sciences, Wuhan University, Wuhan, P. 6 School of Public Health, Key Laboratory of Public Health Safety of the Ministry of Education and Key Laboratory of Health Technology Assessment of the Ministry of Health, Fudan University, Shanghai, P.5 Shanghai Environmental Monitoring Center, Shanghai, P.4 Division of Environment and Sustainability, The Hong Kong University of Science and Technology, Hong Kong, P. 3 State Key Laboratory of Virology, Modern Virology Research Center, College of Life Sciences, Wuhan University, Wuhan, P. 2 Division of Environment and Sustainability, The Hong Kong University of Science and Technology, Hong Kong, P.1 State Key Laboratory of Virology, Modern Virology Research Center, College of Life Sciences, Wuhan University, Wuhan, P. ![]() Perhaps those dead calves were salvaged to make parchment. Females are more valuable if you want to grow your herds, so why would you kill so many females to make parchment? Collins and Fiddyment consulted with Annelise Binois-Roman, a zooarchaeologist, who noted that a cattle plague swept through England in the years before the York Gospels were created. Four of the five whose sex they could determine from DNA were female, which they found highly unusual if representative. They also looked at the sex of the calves. Three of the samples yielded enough DNA to compare to modern cattle genomes, and the single most complete parchment genome was similar to modern Norwegian reds and Holsteins. They analyzed eraser dust from eight pages. With the York Gospels, Collins and Fiddyment went one step further to look for DNA with the eraser technique. “I felt like the voice in the wilderness.” They found that uterine vellum is indeed from calves, sheep, and goats, though not necessarily unborn ones. The team published a study in 2015 analyzing proteins rubbed off of uterine vellum. Others, however suggested the skin came from different animals entirely, like squirrel or rabbit. White plastic erasers made by Staedtler turned out to be perfect for cleaning manuscripts and for collecting DNA.Ĭollins and Fiddyment had previously collaborated with Holsinger to use the eraser technique to study proteins from uterine vellum-so named because it is so thin that people thought that they were made from the skin of unborn livestock. She ended up shadowing conservationists for several weeks and learned about their eraser technique. Matthew and I didn’t think of it,” says Fiddyment. “They told us we would not be allowed to sample the parchments. When Collins and postdoctoral researcher Sarah Fiddyment first approached archives to collaborate though, they made the mistake of thinking like archaeologists used to routinely pulverizing bone for DNA analysis. And you didn’t even need to go out into the field and dig. ![]() “You look at these shelves, and every one of them has a skin of an animal with a date written on it,” he says. So Collins got to thinking about archives full of old manuscripts. “You can imagine the frustration,” says Collins. There were thousands of bones on the site, but only six that they tested yielded DNA-too few for any statistically significant results. A few years ago, he had a graduate student trying to extract ancient DNA from animal bones at an old Viking settlement. The idea to study parchment came to Matthew Collins, an archaeologist at the University of York, after a failed study in bones. It allows a lot of different manuscripts from a lot of different areas to be analyzed together,” says Bruce Holsinger, an English professor at the University of Virginia who is writing a book about parchment. “That’s why it’s such an exciting breakthrough. Archivists are loathe to allow researchers to cut off a piece of, say, the York Gospels, but some eraser crumbs? Sure. Scientists have extracted DNA from parchment before, but this non-destructive technique expands the potential pool of research material. It’s part of a growing movement to bring together scholars in the sciences and humanities to study medieval manuscripts. Using DNA, researchers might track how a disease changed the makeup of a herd or how the skin of sheep from one region moved to another medieval trade routes. Every one of these books is a herd of animals. If their technique works, it could revolutionize the use of parchment to study history. The authors report their findings in a preprint that has not yet been peer-reviewed, though they plan to submit it to a scientific journal. All they needed were the crumbs from rubbing the book with erasers, which conservationists routinely use to clean manuscripts. Remarkably, the authors say they extracted all this DNA without destroying even a tiny piece of parchment. Illustrated page of the York Gospels (Courtesy of York Minster) ![]() Should only some of these facets be damaged, a dragon would still have limited vision in the remaining ones. They had multifaceted eyes that changed color depending on the dragon's mood. Unlike Terran species, dragon ichor did not have different types, and giving a dragon a transfusion of ichor from another dragon would never make them sick. ![]() Their blood, referred to as ichor, is copper-based and green in color. Like all of Pern's native large fauna, they had six limbs - four feet and two wings. Weyrholds could then work to support dragon upkeep on their own (such as raising their own herdbeasts and the like), without having to depend on others.ĭragons were carnivorous, oviparous, warm-blooded creatures. The idea was that when Thread no longer falls, the dragonriders' time will be freed up to establish their own specialized holds, generally in locations that satisfy draconic needs but are less attractive to large human settlements. In particular, F'lessan spearheaded this effort with the first " Weyrhold" at Honshu Weyrhold. This drove weyrleaders to seriously consider how they would live with dragons after the Ninth Pass when Thread was no longer a threat. In turn, the dragonriders were often resentful of what they deemed a lack of respect towards them. This was known to cause resentment among those doing the tithing, especially at times when Thread was not falling. The arrangement of donations to the weyrs was called "tithing". However, the great beasts required a good deal of maintenance and food, to the degree of requiring a large part of Pernese infrastructure - especially cattle farming - to be centered around their upkeep. Later genetic manipulation by Ping's granddaughter, Wind Blossom, also resulted in the watch-whers, which were ungainly, nocturnal creatures who bore a slight resemblance to dragons.Īs the primary line of defense against the Thread, dragons were a requirement for the survival and prosperity of humans and all other forms of land life on Pern. The dragons were named after their resemblance to Western dragons from the legends of old Earth. Geneticist Kitti Ping Yung designed the dragons by manipulating the genetic code of the indigenous fire lizards that had been acquired as pets by the colonists. In Dragonsdawn, the race was intentionally engineered to fight Thread after it first caught the human colonists on Pern unawares, with devastating results. 8.2.1 Dragon Riders: Chronicles of Pern (2001). |
