![]() In a classic paper, Mercer warned that the western part of Antarctica was so vulnerable to human-induced climate warming as to pose a “threat of disaster” from rising seas. The collapse of the peninsula’s ice shelves can be interpreted as fulfilling a prophecy made in 1978 by a renowned glaciologist named John H. The Antarctic Peninsula may be a canary in a coal mine. “But if you take away Bawden, the whole shelf will feel it.” “We’re not even sure how it’s hanging on there,” he said. Scientists have yet to determine the extent of thinning around the Bawden and Gipps ice rises, though Rignot noted that the Bawden ice rise was more vulnerable. ![]() Ice rises are islands that are overridden by the ice shelf, allowing them to shoulder more of the weight of the shelf. “If the shelf is getting thinner, it will be more breakable, and it will lose contact with the ice rises.” “You have these two anchors on the side of Larsen C that play a critical role in holding the ice shelf where it is,” he said. Scientists aren’t sure, but they’re worried.Īccording to Rignot, the stability of the whole ice shelf is threatened, as the shelf front thins. The glaciers will feel less resistance to flow, effectively removing a cork in front of them.” “If the ice shelf breaks apart, it will remove a buttressing force on the glaciers that flow into it. “At that point in time, the glaciers will react,” said Eric Rignot, a climate scientist at the University of California, Irvine, who has done extensive research on polar ice. If the front retreats past that line, the northernmost part of the shelf could collapse within months. When an ice shelf collapses, the glaciers behind it can accelerate, as if the drain pipe had suddenly cleared.Īt the remaining part of Larsen C, the edge is now much closer to a line that scientists call the compressive arch, which is critical for structural support. The result is a bit like a clog in a drain pipe, slowing the flow of the glaciers feeding them. In frigid regions, ice shelves form as the long rivers of ice called glaciers flow from land into the sea. What happens if the Larsen C ice shelf collapses? Wagner, who leads NASA’s efforts to study the polar regions. “While it might not be caused by global warming, it’s at least a natural laboratory to study how breakups will occur at other ice shelves to improve the theoretical basis for our projections of future sea-level rise,” said Thomas P. But the two camps agree that the breakup of ice shelves in the peninsula region may be a preview of what is in store for the main part of Antarctica as the world continues heating up as a result of human activity. Some climate scientists believe the warming in the region was at least in part a consequence of human-caused climate change, while others have disputed that, seeing a large role for natural variability - and noting that icebergs have been breaking away from ice shelves for many millions of years. That warming had slowed or perhaps reversed slightly in the 21st century, but scientists believe the ice is still catching up to the higher temperatures. In the late 20th century, the Antarctic Peninsula, which juts out from the main body of Antarctica and points toward South America, was one of the fastest-warming places in the world. But in other parts of Antarctica, similar shelves are holding back enormous amounts of ice, and scientists fear that their future collapse could dump enough ice into the ocean to raise the sea level by several metres. Larsen C, like two smaller ice shelves that collapsed before it, was holding back relatively little land ice, and it is not expected to contribute much to the rise of the sea. In this case though, the iceberg is already floating so there won’t be a substantial sea level change. The new iceberg contains so much mass that if all of it were added anew to the ocean, it would drive almost three millimetres of global sea level rise (it takes 327 billion tonnes of ice to produce one millimetre of ocean rise). Raw: Scientists study whales in Antarctica With global warming, Antarctica going from glacial to green Maps will need to be redrawn.”Ī huge crack across one of Antarctica’s largest ice shelves is nearing its breaking point “The remaining shelf will be at its smallest ever known size,” said Adrian Luckman, a lead researcher for Project Midas. The exact cause of the crack is not clear - scientists say it may not be a result of climate change - but the event fundamentally changes the landscape of the Antarctic Peninsula, according to Project Midas, a research team from Swansea University and Aberystwyth University in Britain that had been monitoring the rift since 2014.

My fascination with the Blues began that year with Hooker and other blues artists. While other teens were listening to Twist songs on radio by Chubby Checker, I was groovin' to Hooker's BOOM BOOM and other songs. I recall when BOOM BOOM hit the radio airwaves on blues stations in 1962. When I was a teen, I used to listen to R&B and Blues radio stations from Louisiana and Arkansas at late night. Rocky from Tulsa, OkWhat a song!! I'm a fan of John Lee Hooker from way back.When Boom Boom was played, they brought down the house!! It is a blues song, but it is an "all out rocker!!" About ten or 12 years ago, Eric Burdon reunited with the Animals for a U.S. Mercy! This version still can "raise the dead" if ya know what I mean. Last year (2013), ABKCO Records released a "Best of The Animals" CD with digitally remastered songs, to include Boom Boom. And I am not sure, but think Boom Boom was on it too. Hooker did a double album with Canned Heat in the Seventies I really loved too. What a blues master! It's unfortunate that VeeJay Records in Chicago folded up and cheated so many of its artists (the Four Seasons included!) of royalties and other monies due them. Then later, I learned it was written & recorded by Hooker. Not many of us kids paid much attention to the Billboard charts back then. In this area back in '64 I recall it was on our local rock charts Top Ten. ![]() ![]() You can hear the song playing as artillery explodes! I first hear this song as the Animals' version from 1964 when I was in high school. Rotunda from Tulsa, OkWhen the James Bond movie "Skyfall" came out last year, The Animals' version of "Boom Boom" was in the soundtrack near the movie's end-when Bond is holed-up in that huge old house awaiting the final confrontation with villains.Torty from TucsonI thought the Animals stole the tune for this song from Spinal Tap's song Gimme Some Money, but not only do I find out that Hooker wrote this well before Spinal Tap, the Animals actually recorded it a year before Spinal Tap's song.Hooker passed away on June 21st, 2001 at the age of 83. Barry from Sauquoit, NyOn May 20th 1962, "Boom Boom" by John Lee Hooker entered Billboard's Hot Top 100 chart at position #100 eight weeks later on July 15th, 1962 it would peak at #60. No matter the material, you get powder-free gloves designed to fit as comfortably as classic latex gloves. We offer medical gloves in three material options: When you need medical exam gloves you can trust, don’t settle for just any glove. Tips in Choosing the Perfect Medical Grade Gloves Vinyl gloves are made from plastic resin and are popular for their affordability and ability to resist alcohols and other solvents.Įach type of medical-grade glove has unique benefits, so it's important to choose the right glove for the task. Nitrile gloves are made from synthetic rubber and are popular for their strength and chemical resistance. They are popular for their fit and comfort, as well as their resistance to tears and punctures. Latex gloves are made from natural rubber latex, which is highly elastic and durable. Some of the most common types include latex gloves, nitrile gloves, and vinyl gloves. There are a wide variety of medical grade gloves available on the market. Vinyl gloves are made from plastic and protect against bacteria but not viruses or chemical spills. Neoprene gloves are made from synthetic rubber and protect against oils and acids. ![]() They are also latex-free, making them ideal for people with latex allergies. Nitrile gloves are made from synthetic rubber and are resistant to various chemicals. Nitrile, neoprene, and vinyl are the most common materials used in medical-grade gloves. What are the common materials used in medical-grade gloves? Non-disposable gloves can be washed and reused multiple times, but they are more expensive and require a bit more care to keep them clean. Disposable gloves are generally cheaper and easier to use, but they must be discarded after each use. Medical-grade gloves are available in both disposable and non-disposable varieties. They often have extra features, such as textured fingertips, that make them better suited for medical tasks. They are typically made of a thicker and more durable material than standard gloves. Medical-grade gloves refer to gloves that have been manufactured specifically for medical use. They are made of a higher-quality material than standard gloves, providing a higher level of protection against infection. Medical-grade gloves are gloves that have been designed and manufactured specifically for medical use. That way, you can focus on the things that matter, like going the extra mile for your patients. ![]() They’re designed for maximum performance, comfort, and protection. ![]() That’s why our disposable medical gloves are here to change the way you think about disposable sterile gloves. You need gloves that work just as hard as you do. Whether you’re dealing with bodily fluids, screen readers, chemicals, or just a fussy patient, you don’t just need medical gloves for sale. And every medical professional counts on medical exam gloves to deliver that care. Your patients count on you to deliver lifesaving medical care. ![]() Trigger for constraint source_t_id_fkey: time=0.557 calls=1 > Index Scan using source_t_id_idx on source The queries are as fast as they should be: Trigger for constraint source_t_id_fkey: time=153.804 calls=1ĬREATE INDEX source_t_id_idx ON source (t_id) > Index Scan using target_t_name_idx on target Looking up source rows via the link to target and deleting rows from target is unreasonably slow: SELECT i, (i - 1) % 500000 + 1, 'source ' || iĪDD FOREIGN KEY (t_id) REFERENCES target * set hint bits and collect statistics */ Without an index, this requires a sequential scan of the source table. It does so by searching if there are rows in the source table that would become orphaned by the data modification. Then PostgreSQL has to check if the foreign key constraint is still satisfied. You delete rows or update key columns in the target table. If there is an index on the columns at the source, PostgreSQL can use an efficient nested loop join.Ģ. You perform a join between the two tables where you explicitly search for the source rows referencing one or a few target rows. The typical cases where you need that are:ġ. However, such an index is quite useful for finding all source rows that reference a target row. In contrast to the above, PostgreSQL requires no index at the source of a foreign key. The index also comes handy if you want to find the row in the target table that matches a row in the source table. This is required so that there is always a well-defined row to which the foreign key points. Consequently, the target side of a foreign key is automatically indexed. Such constraints are implemented with unique indexes in PostgreSQL. The referenced columns in the target table must have a primary key or unique constraint. In the following, I will call the table, on which the foreign key constraint is defined, the source table and the referenced table the target table. This article will explain that and show you how to search for missing indexes.

More studies need to be done on how the magnitude of these floods and their recurrence interval are related to how often these chute cutoff channels form. ![]() Ī chute cutoff channel can form during a flood resulting in an overbank flow where water goes over the banks of the river, creating erosion of the surrounding landscape. Chute cutoff: a channel cuts directly across the land bypassing an entire meandering loop in the river and abandoning it.On the outer bends of a river, where water is flowing fastest, the river will erode away the land between adjacent outer bends and cause them to become close to each other this leads to their intersection. Neck cutoff: a river bend intersects itself.As these old meanders are cutoff from the rest of the river, a new channel, or cutoff channel, is formed. Cutoff channel Ī river constantly evolves and as it does, meanders that were once a part of the river are abandoned in favor of a route that is more efficient for a river to take. Meandering rivers trend in the direction of increasing sinuosity. Braided rivers do not follow this same convention. Between these values, a river is described as sinuous which describes those in a transitory state between the two states. A sinuosity value of less than 1.1 is a “straight” river. Meandering rivers have a sinuosity value/ratio of greater than 1.5. Three conventional categorizations of rivers or their reaches exist. It is expressed as the ratio of the distance between two distant points in a river following the middle-of-the-river course of the river as compared with the straight distance between those points. The term is equally used to describe the actual incidence of and potential tendency of a river to curve or meander over its length. Rivers are commonly described and interpreted by their sinuosity. On the inside bend of a river, the level is lower, secondary flow moves sand and gravel across the river bed creating shallows and point bars, and friction of air and perturbances of the bed act against a higher proportion of the column of water, being shorter, slowing the water to varying degrees. Meandering rivers flow higher and hence with more total flow, pressure and erosion on the outside of their bends due to forming a vortex as in a stirred coffee cup and consequently the river erodes more the outer bank. Rivers form meanders as they flow laterally downstream, see sinuosity. Cutoffs are a natural part of the evolution of a meandering river. The steeper drop in gradient (slope) causes the river flow gradually to abandon the meander which will silt up with sediment from deposition. Animation of the formation of an oxbow lakeĪ meander cutoff is a natural form of a cutting or cut in a river occurs when a pronounced meander (hook) in a river is breached by a flow that connects the two closest parts of the hook to form a new channel, a full loop. ![]() In case you’re wondering what a digital planner should include, there’s a simple answer. ![]() With this in mind, always read exactly what a digital planner includes.ĭefinitely, I highly recommend watching the flip-through videos. ![]() Last but not least, a digital planner may or may not include some of the planner collections ( for instance, meal planners, habit trackers, fitness trackers, etc).

I sent a mood board I created for Logan, some color palette ideas for her suit, and a description of her personality to give Héctor some idea of what I was thinking. "After the editor, Sarah Brunstad, made the introduction, we got right to work visualizing Logan. "It was enjoyable working with Héctor," Williams adds. It wasn’t until I got the tap for Marvel’s Voices that I began reaching out for the materials to bring Logan to life."
