Warm Weather Breaks Up Kuskokwim River

Temperatures were cold in early November but over the past several days, temperatures have reached into the 40s and even the 50s in some places along the river.Download AudioCelina Van Breukelen is a hydrologist with the National Weather Service and the River Forecast Center in Anchorage. She says they’ve had reports of the ice moving at Napaimute and Aniak.“There seems to be some sort of a localized breakup at some locations on the river. We don’t expect it to have a flood impact. We don’t think that the ice is thick enough or that the water levels are high enough to really create a flood event, more of just some local breaking up that’s happening,” said Van Breukelen.The situation has thousands of residents in a transportation standstill as they wait for the Kuskokwim to freeze into a safe road for travel. Van Breukelen says the forecast calls for temperatures to begin dropping below freezing at night and that should slow down melting.“That should help slow that process down a lot. Not expecting to see a lot of precip that’s going to add a lot of precip that’s into the river and there should not be a whole lot of snow to melt, so not expecting to see much more input into the river over the next few days,” said Van Breukelen.Mark Leary, who lives in Napaimute, says this is the third time he’s seen a November breakup – besides this year, it’s happened in 2002 and 2010. He says it’s different than a spring one, especially how it sounds.“It’s real hard and it sounds like rocks moving. There’s no needle ice like in the springtime to soften some of the sound. Rocks tumbling down a hillside, rocks gritting, rocks grinding. The difference now as opposed to a spring breakup, the night is long you know. You don’t know what’s happening during the night, you know it’s like 14 hours of darkness and you don’t know what’s going on – you can hear it but you don’t know and it’s a little bit scary,” said Leary.Leary says although the National Weather Service is not calling for flooding now, if ice jams form near villages and re-freeze, it could mean trouble this spring.“That’s what happened at Crooked Creek in 2010, it broke up in November right around Thanksgiving and then it jammed a few miles below their village and refroze and boy, that jam was hard as a rock. So the next spring, 2011 that jam couldn’t melt as fast as the regular ice. And that’s what caused the new jam in the spring of 2011 that hit Crooked Creek really hard,” said Leary.A pilot flew the Kuskokwim River today to assess the extent of the breakup and reports an ice jam below Aniak. National Weather Service officials say some local surges of water are expected as the ice runs. They say people should move belongings and equipment away from the river, but they do not expect high enough water to impact homes or roads. Alaska State Troopers are warning people not to travel on the river.last_img read more

Vomiting why so common in kids

first_imgVomiting or emesis as it is medically known, is same in children as well as in adults say medical experts. There may be triggers such as motion sickness, certain medications, unpleasant sights or smells, viruses that may irritate the inside walls of the stomach, overfeeding etc. In children the sensitivity of the vomiting centre in the brain is higher than in adults that results in frequent vomiting.The stomach nerves are called afferent nerves. When these are stimulated, they send signals to the brain telling it to start a vomiting reaction to expel what has been ingested. Once triggered, the opening of the lungs and airways or the larynx shuts off after a deep breath and the upper palate rises while the glottis folds back. The diaphragm pushes the contents of the abdomen by pushing down. This creates a negative pressure that opens up the esophagus or the food pipe. The food from the stomach heaves back via the esophagus outside the body in a forceful flow of vomit as the abdominal walls tighten to provide additional force.   Related StoriesAn active brain and body associated with reduced risk of dementiaResearchers identify gene mutations linked to leukemia in children with Down’s syndromeResearch team to create new technology for tackling concussionIn children the triggers are much more innocuous than in adults. This includes a fever, a viral infection or even a painful stimuli or an emotional upset. Paediatricians like pediatric gastroenterologist Katja Kovacic explains that for children the causes can be numerous. Stomach flu or food poisoning could be one of the commonest causes but there may be harmless causes of vomiting in children as well.According to paediatricians the best thing to do when a child vomits is to clean up and make the child comfortable. Fluid intake is vital to prevent dehydration. IF there are certain warning signs such as excessive drowsiness, lethargy, distended abdomen, abdmoninal pain that is severe, any other severe pain etc., the parents and caregivers should seek medical attention says Kovacic. Vomiting that is excessively forceful or very frequent and does not seem to ease within a day is also a red flag says Koacic because it may have an underlying surgical cause and also lead to dehydration. Other experts warn that blood in the vomit, dark green bile, or fecal matter in the vomit may indicate an obstructed bowel and needs immediate medical attention.Kovacic says that frequent vomiting could also indicate a condition called cyclic vomiting syndrome where there are repeated bouts of vomiting that can last for several hours at a time. The cause is not known but some children may benefit from anti-migraine drugs says Kovacic. Migraine in adults could manifest as repeated vomiting episodes in children say experts.

This is a global phenomenon most parents have resigned themselves to. Researchers have now tried to understand why kids vomit so commonly and if there is actually any reason for parents to panic. An article by Erin Blakemore for NPR looks to answer the question.center_img Source:https://www.npr.org/sections/health-shots/2018/09/10/645723728/the-queasy-truth-about-why-kids-are-so-prone-to-vomitinglast_img read more
