Researchers from Florida Atlantic University released a video on Tuesday that shows how droplets disperse into the air from a person’s mouth.The researchers used different kinds of masks to analyze the disbursement of the droplets. The researchers also showed that without a mask, six feet of distance might not be enough to avoid infection.The FAU team tested a single-layer bandana-style covering, a homemade mask that was stitched using two-layers of cotton quilting fabric consisting of 70 threads per inch, and a non-sterile cone-style mask that is available in most pharmacies. The team used a mannequin, Laser lights and synthetic fog to help visualize the spread of the droplet from a cough..The researchers said that stitched quilted cotton masks worked the best in the simulation, with droplets from emulated coughs traveling just 2.5 inches from the mask. By comparison, without a mask, the droplets moved more than 8 feet, with some droplets traveling up to 12 feet during a heavy cough. The researchers also noted that the droplets remained suspended in midair for up to three minutes in the simulated environment.“We found that although the unobstructed turbulent jets were observed to travel up to 12 feet, a large majority of the ejected droplets fell to the ground by this point,” said Dhanak. “Importantly, both the number and concentration of the droplets will decrease with increasing distance, which is the fundamental rationale behind social-distancing.”FAU said that droplets from a cough traveled 3 feet, 7 inches from a bandana; 1 foot, 3 inches from a folded handkerchief; and 8 inches from a cone-style mask.“Preliminary results from our experiment reveal that significant concentrations of small particles from a turbulent jet such as from a heavy cough/sneeze can linger in still air for more than one minute. It only took the particles a couple of seconds to travel 3 feet; in about 12 seconds it reached 6 feet and in about 41 seconds it reached around 9 feet,” said Siddhartha Verma, an assistant professor in FAU’s Department of Ocean and Mechanical Engineering.Last week, the University of Washington’s Institute for Health Metrics and Evaluation projected that 33,000 American lives would be saved between now and October 1 by near universal wearing of masks.Last month, a study in the Lancet found that the use of masks and respirators by those infected with the virus reduced the risk of spreading the infection by 85%. The authors analyzed data that showed that N95 respirators in healthcare settings were up to 96% effective. Other masks were found to be 77% effective.The CDC issued guidance in April to recommend mask wearing while in public, which has become a requirement to enter retail establishments in more than a dozen states.The CDC's guidance stressed several points: That wearing a face covering is not a substitute for social distancing, and that the public should not use medical or surgical masks. The recommendations suggest the public should use fabric or cloth that covers the mouth and nose.To view FAU's video, click here. Justin Boggs is a writer for the E.W. Scripps National Desk.

RAMONA, Calif. (KGTV) - A Ramona couple walking their yellow Labrador puppy say they were attacked by two pit bulls Tuesday night, suffering serious injuries.Michael Dougherty was walking with his wife, Dee, in the Kmart parking lot in the 1800 block of Main Street training their puppy, Rueger. Dougherty said it's easier in the parking lot, as there is more light, compared to their rural neighborhood.As they walked toward the Taco Shop, around 7:15 p.m., Dougherty said from the corner of his eye, he saw two pit bulls charging.RELATED: Dog and owner mauled by pit bull during walk in OceansideThey attacked Rueger and his wife, who went down trying to rescue the dog. Dougherty is recovering from a back injury and walks with a cane. He used it as a weapon."I just started beating the dog, beating the dog, until it [the cane] snapped. This fell down alongside the dog and my wife and she grabbed this and was jamming it into the dog's mouth. When this broke I started punching the dog in the head."Eventually they were able to separate all three dogs. No one escaped uninjured. Dougherty described his wife's wounds, "the top fang went in," gesturing at his left cheek, "and the bottom fang went under her chin like this."RELATED: Pit bull comes to defense of injured owner in apartment, chases away attackers"Both arms are bitten up quite a bit, I couldn't even count them there were so many," he continued, saying her hand bore the worst injury. "Her thumb was bitten three quarters of the way around," saying the skin had been pushed up, away from her hand. "She said she could see the bone, but I don't know about that."Dougherty suffered a bite to his hand as well.As he called 911, he saw the owner and the two pit bulls walking away."It's frustrating to think that he didn't have the courage to stand here and be responsible for what his animals did."RELATED: Family trying to save 'sweetest pit bull on earth' after authorities recommended it be euthanizedDougherty said they don't know how much his wife's emergency room trip will cost. They have a 0 veterinarian bill and said his wife is anxious when he leaves the house.Dougherty hoped by telling their story he would "make people aware and maybe get some information to get this wild animal off the street. He was plain vicious."Animal Control confirmed they have a dog in quarantine, and will have the couple identify Friday whether it's the same dog who attacked them.Dougherty has a GoFundMe set up to help with his wife's expenses. His son said she will be out of work while she recovers. 2572

Refugees who have waited years to get to the United States sometimes arrive only to find out their life's work does not translate to opportunities in America.Pima County Public Libraries have a unique approach to helping those who are new to the city and country.Librarians are helping immigrants and refugees from all over the world adapt to U.S. Culture by helping their degrees earned overseas recognized here in America.Henri Nzeyimana was born in Burundi. In late-April 2015, political unrest took over the East African country. It resulted in an attempted coup d'état. Hundreds of civilians were killed, and thousands of peaceful political demonstrators were tortured.Nzeyimana is an asylum seeker that has been in the U.S. for three years. "Every time you have to leave your country and go to another country — not because of your choice but because you're not able to enjoy freedom — it hurts," Nzeyimana explained. He decided to move to Tucson to find work —  task that he initially thought was impossible."To hear that you've been at school for more than 10 years, working for more than 20 and then all of a sudden you have to start fresh, that was traumatizing," he said.  However, that changed when he met Citizenship Librarian Mary Givins at the Eckstrom-Columbus Library. Since he has two masters degrees from two different European universities, Givins thought if he could get a hold of his transcripts he can get at least a substitute teacher degree in America.After some thinking, that's exactly what he did."I showed him the process for getting his degree evaluated, translated from French and then he had that paper submitted to the department of education," Givins said.Givins says immigrants and refugees don't realize that the degrees they receive from their countries often transfer to the U.S. She says all it takes is a lot of steps to get them started. "If people have access to their transcripts from their university, then something can be done," she explained. All the Pima County Public Library branches offer the "Job Help Program," twice a week. It provides support for degree translation and evaluation.The primary goal is to get the diplomas earned overseas recognized here in the U.S. A bonus for those in the program is working with librarians to create resumes and even apply for jobs. Click here to get more information. 2426
