Commercial shrimp farming began in the s, and production grew steeply, particularly to match the market demands of the USA, Japan and Western Europe. The total global production of farmed shrimp reached more than 1. The largest exporting nation is Thailand. Shrimp farming has moved from China to Southeast Asia into a meat packing industry. Technological advances have led to growing shrimp at ever higher densities, and broodstock is shipped worldwide. Virtually all farmed shrimp are penaeids i.

And they are all completely FREE to visit! But with so many interesting historical and archaeological sites here, we"ve provided in-depth information about the most important sites for you to explore. Westness Heritage Walk The most impressive of the archaeological sites can be found along the most important archaeological mile in Scotland, which covers thousands of years of history in just one mile-long rough coastal path, known as the Westness Heritage Walk.
This amazing trail takes you on a journey through the first Stone Age settlers from over 5, years ago , to the Pictish Iron Age, the Viking invaders, the time of the Earls, and the crofting clearances of the early s. Built around 3, B. This is an excellent example of an"Orkney-Cromarty"-type stalled cairn, with a central passageway that is flanked by pairs of stones separated into 12 compartments. Low stone benches were constructed between several of the stalls, with burials on top.
The outer wall base was constructed using flat horizontal slabs of stone, with more slabs then laid at an angle in a"herring-bone" style, with alternating layers, similar to the patterns found on Unstan Ware pottery. Known as the"Great Ship of Death", excavation of the site - following its discovery in - uncovered the remains of 25 people, found in crouched positions either on or under the eastern shelves of the chamber.
Two burials of a later date were also discoverd. Also found during excavation were the bones of birds such as buzzard, eagle, gannet, skua , fish, oxen, pig, red deer, and sheep, indicating that the people were farmers and hunters, as well as confirming the existance of deer on Rousay in the past, as there is no longer any in the Orkney Islands today. A suspended walkway enables you to get a bird"s-eye-view of this wonderful site.

History[ edit ] Link farms were developed by search engine optimizers SEOs in to take advantage of the Inktomi search engine"s dependence upon link popularity. Although link popularity is used by some search engines to help establish a ranking order for search results, the Inktomi engine at the time maintained two indexes.
Search results were produced from the primary index which was limited to approximately million listings. Pages with few inbound links fell out of the Inktomi index on a monthly basis. Inktomi was targeted for manipulation through link farms because it was then used by several independent but popular search engines.
On the World Wide Web, a link farm is any group of web sites that all hyperlink to every other site in the group. In graph theoretic terms, a link farm is a gh some link farms can be created by hand, most are created through automated programs and services. A link farm is a form of spamming the index of a web search engine (sometimes called spamdexing).
What is hemp and why is everybody talking about it? Here are a few facts to feed your head And they"ve been doing so for thousands of years. View a timeline of hemp throughout history here. It can get up to 15 to 20 or so feet tall. It is an annual, herbaceous, long fibre plant similar to flax linen , jute and ramie. However, it"s good at doing almost anything else except making you"high".
You"ll learn more about its versatility in this document. If you smoke hemp you will likely get a headache. You will not get"high". But during the s, the U. In a blatant case of mistaken identity, industrial hemp was banned along with it. Hemp"s potential for producing paper also posed a threat to the timber and oil industries. Evidence suggests that commercial interests, having much to lose from hemp competition, helped propagate the reefer madness hysteria and used their influence to lobby for Marijuana Prohibition.

Could not subscribe, try again laterInvalid Email If on your next walk in the countryside you should happen to see a sheep lying on its back with its legs in the air, you might just be able to save that sheep"s life. Sheep do not naturally lie on their backs and they cannot easily right themselves. So if you find one in that position there"s a chance it could be in trouble. Now sheep dog trainer Andy Nickless has made a video showing how people can help get a sheep that"s stuck back on its feet again.
How do sheep get stuck? According to the Working Sheepdog Website , a sheep is at risk of getting stuck on its back if it is heavily pregnant, it has a heavy, possibly wet fleece or it"s simply too fat. But once stuck on its back, it"s vulnerable to attack from predators such as crows. What"s worse, it could be on a countdown to suffocation. Grass fermenting in its stomach produces gas, and if the sheep is on its back the gas can"t escape.
As the gas builds up in the sheep"s stomach it causes pressure on the lungs, eventually preventing it from breathing. What to do if you find one on its back Andy Nickless shows how to take hold of a sheep"s legs or fleece and turn it over in his video. You might even need to do it again if it rolls too far and ends up on its back again, he warns. But as soon as it is able it"s likely to get back on its feet and run to join the rest of the flock - although it might be a bit wobbly at first.

Pottery in archaeology Introduction The following is a basic introduction to pottery in archaeology, focusing particularly on the ceramics of the medieval period. The bibliography at the end provides references to more detailed and comprehensive sources. The study of pottery is an important branch of archaeology. This is because pottery is: Occasionally whole vessels are found, particularly where they have been used as grave goods or cremation"urns".
These are important in providing us with a type series of vessel forms, although broken vessels can be just as useful for this. Prehistoric and Roman pottery: Prehistoric pottery is handmade i. The clay from which it is made often contains pieces of burnt flint or other stone and the pottery appears very coarse.
This crudeness is related to the function of the vessels, which had to withstand thermal shock when placed on a fire for cooking.

So suggests new research that tracked changes in two genes thought to help regulate brain growth, changes that appeared well after the rise of modern humans , years ago. That the defining feature of humans — our large brains — continued to evolve as recently as 5, years ago, and may be doing so today, promises to surprise the average person, if not biologists. Lahn and colleagues examined two genes, named microcephalin and ASPM, that are connected to brain size. If those genes don"t work, babies are born with severely small brains, called microcephaly.
Using DNA samples from ethnically diverse populations, they identified a collection of variations in each gene that occurred with unusually high frequency. In fact, the variations were so common they couldn"t be accidental mutations but instead were probably due to natural selection, where genetic changes that are favorable to a species quickly gain a foothold and begin to spread, the researchers report.
Lahn offers an analogy: Medieval monks would copy manuscripts and each copy would inevitably contain errors — accidental mutations. Years later, a ruler declares one of those copies the definitive manuscript, and a rush is on to make many copies of that version — so whatever changes from the original are in this presumed important copy become widely disseminated.
Scientists attempt to date genetic changes by tracing back to such spread, using a statistical model that assumes genes have a certain mutation rate over time. For the microcephalin gene, the variation arose about 37, years ago, about the time period when art, music and tool-making were emerging, Lahn said. For ASPM, the variation arose about 5, years ago, roughly correlating with the development of written language, spread of agriculture and development of cities, he said.
Other scientists urge great caution in interpreting the research.
