We can usually recognize friends and acquaintances by their voices. If we all have the same hardware, though, how is this possible? The answer is in the vortex. Sounds sci-fi, but researchers at the University of Cincinnati used knowledge of jet engines to explore the possibility that vortices may help solve the mysteries of the voice. Vortices are not body parts; they are aerodynamic effects of airflow through the voice box (larynx). If you could see them, they would look like rotating smoke rings. The article says, “the larynx is one of the body’s least understood organs.” Most researchers have studied the structure of the larynx, but Sid Khosla and his team looked at the airflow through it. They knew that vortices around jet engines produce sound, and suspected that similar phenomena modulated the otherwise mechanical vibrations of the larynx, giving it tone and color. As a result, they were the first to produce an animal model that could be used to explain the intricacies of voice production in humans. Khosla found that “vortices may help explain why individual voices are different and can have a different richness and quality to their sound.” Vortices can be produced by a number of mechanisms. “This complexity produces a sound that makes my voice different from yours,” he said. The team hopes that new insights into the aerodynamics of voice production may lead to more effective treatments for voice disorders.Good science, new knowledge with possible health benefits, and no evolutionary speculation.

Share Facebook Twitter Google + LinkedIn Pinterest By Chris ClaytonDTN Ag Policy EditorHAMBURG, Iowa (DTN) — Iowa Gov. Kim Reynolds toured flooded areas of the southwest corner of her state on Monday, making a point that she was waiting to hear if and when Congress would give final approval for a disaster-aid package.The House of Representatives voted 354-58 late Monday to approve the long-awaited $19.1 billion disaster aid package that will address not only Midwest flooding, but also aid recovery from hurricanes in the Southeastern states last year as well as the California wildfires. The bill now goes to President Donald Trump, who is expected to sign it.The bill specifically includes just over $3 billion to pay for farmer losses from disasters that occurred in 2018 and 2019. The bill will help pay for farmers who lost stored grain this spring during flooding, and also includes a provision that raises prevented-planting coverage up to 90% of potential losses.“We had run into a dead-end to help our farmers who had a tremendous amount of grain stored and the impact that had on our economy and to our farmers and their ability to come back,” Reynolds said. “The fact that we got that language in there was instrumental.”The vote comes as the Missouri River again is rising because of continual rain throughout the basin. The state of Missouri has shut down more than 400 roads because of flooding on both the Missouri and Mississippi rivers. The Arkansas River is also inundating farm ground in Oklahoma and Arkansas, and locks and dams on the Mississippi River remain shut down as the Corps of Engineers looks for ways to relieve pressure on the system.Flooding in southwest Iowa had receded to a point that state bridges across the Missouri River had reopened, as well as Interstate 29 to Missouri. But constant rainfall and an increase in water flows on the river had re-flooded much of the river bottom. Reynolds was surprised how much the water had again risen.“I just wasn’t prepared to see what looks like a lake out the window,” the governor said. “I was taken aback by the amount of the water.”The prevented-planting language in the bill could prove significant this year as USDA’s Crop Progress report this week highlighted just 67% of expected corn acres are planted as of June 2, as most states now are in the late-planting stage for crop insurance on corn. Soybean planting was estimated at 39% as well, and several states will approach the late-planting stage for soybeans within the next week.Farmers are pushing into late season to get a crop in as USDA officials have indicated the next round of trade-aid payments will be tied to planted acres. Last week, Agriculture Secretary Sonny Perdue indicated USDA may change that requirement, but no announcement has been made. The American Farm Bureau Federation is among the groups urging USDA to alter the way it sets the assistance payments.Leo Ettleman, a farmer in Fremont County, Iowa, was among a handful of farmers who met with the governor in Hamburg as Reynolds got an update on the situation there. Ettleman said passing the disaster package was significant, especially with provisions aiding farmers and funding the Corps of Engineers for recovery efforts.“To get money for that 2018 grain out there that was damaged is encouraging, as well as the prevent-plant changes, as long as it stays for the disaster counties — presidentially declared disaster areas,” Ettleman said. “There’s a lot of prevent-plant across the entire Corn Belt. We feel we have priority where it is presidentially declared.”Going forward, Reynolds said work will be needed to look at crop insurance for farmers affected by the flood to mitigate potential rate hikes they could face next year. She said, ideally, a change should be made to limit rate hikes in counties declared presidential disaster areas. “With what we’re dealing with the prices of commodities and the agricultural economy overall, if they double or triple the costs of the insurance, they just don’t have the resources to do that.”Reynolds, along with the governors of Nebraska, Kansas and Missouri, have been meeting more frequently with the Army Corps of Engineers to look for different management strategies for the Missouri River. R.D. James, assistant secretary of the Army for Civil Works, met with the four governors last week.“It’s effective that we have four governors to hold them accountable,” Reynolds said. “The best thing we can do is have the four of us committed to saying we need the flexibility, we need to do things differently, we need to get back to talking about people and property, and we need to really talk about the flow of the river and the command of the river.”Reynolds said one of the frustrations is that the Corps is often regimented in what it does. She credited the Corps for considering some flexibility in river management. The governor also noted the pressure the flooding and re-flooding has put on the state’s roads as highways were repaired only to again flood out.“We can’t keep putting the funding into our transportation system,” Reynolds said.Several other USDA programs get specific funding under the disaster bill to help farmers, ranchers and forests recover from disasters. The Emergency Conservation Program receives $558 million and the Emergency Watershed Protection Program receives $435 million.The bill also provided $600 million more supplemental disaster nutrition aid for Puerto Rico.For communities affected by disasters, the bill includes $600 million for the Economic Development Administration to provide development grants.For the Army Corps of Engineers, the bill includes, under multiple accounts, just under $2.5 billion total for various flood and hurricane controls, including repairs and emergency operations, as well maintenance and natural disaster repairs.Chris Clayton can be reached at [email protected] him on Twitter @ChrisClaytonDTN© Copyright 2019 DTN/The Progressive Farmer.

The foundation has been very active in promoting healthy eating at its sponsored schools in Providenciales. Together with Mrs. Handfield the Sandals Foundation took the opportunity to not only provide whole-wheat and brand cereals to over five-hundred and thirty-three students at the Five Cays based school but also to provide them with healthy fruits and water. Students were taught the importance of a balanced nutrition and the benefit of healthy eating so that they can make the healthy choices for themselves. The entertaining health seminar hosted by Mrs. Handfield was geared towards empowering, encouraging, and motivating students to get fit. “It is always a pleasure working in collaboration with Beaches Turks & Caicos in giving back to the community. It is especially so being that March is celebrated as National Nutrition Month.” Said Tamika Handfield speaking on the initiative, “Nutrition in Demand’s main mandate is to provide credible, factual and scientifically proven nutrition education to the community. Working along with Beaches afforded us the opportunity to speak to over 500 students of the Enid Capron School about the importance and benefits of eating a healthy breakfast each day.”The mid-morning session saw a group of enthusiastic students who all expressed interest in several exercise routines and asked questions about their favourite foods. The Foundation is no stranger to the health and wellness arena. Over the years the charity teamed up with the Ministry of Health and Human Services and the Wellness and National Health Planning to bring health awareness and distribute fruits and low-fat yogurts to over 1,500 students in providenciales. PR Manager for the Beaches resort Elanor Finfin Krzanowski who spear headed project for the Sandals Foundation also commented on the importance of the event by saying the following, “Teaching the importance of healthy eating to the students of our sponsored schools is a priority for the Sandals Foundation.” She continued, “A well-rounded education not only includes academics but also the knowledge of how to maintain a physical healthy lifestyle. It is the goal of the Sandals Foundation to promote healthy nutrition as well as the importance of a balanced diet and our first step is to provide the fruits to every student of Enid Capron while teaching these basic life-altering skills.”
