Myopia And changes in eye bioassays Young adult.. The analysis included 1,328 participants (age 20) who participated in the baseline assessment and 813 participants who participated in the 8-year follow-up assessment.

Researchers have found that the incidence of myopia and high myopia over 8 years is 14.0 percent and 0.7 percent, respectively. Myopia shifts (≥0.50 diopters in at least one eye) occurred in 261 participants (37.8 percent). Significant vertical changes were seen in the equivalent of a spherical surface, axial length, and lens thickness (0.02 mm per year).There was a significant association between accidental myopia and self-reported East Asian vs. Caucasian race (odds ratio). [OR], 6.13), Female vs. Male Gender (OR, 1.81), Small UV Autofluorescence Area of ​​Conjunctiva (per 10 mm)2 It is reduced, indicating less exposure to sunlight. OR, 9.86), and parental myopia (per parent; OR, 1.57). Female gender and parental myopia were associated with the progression of myopia and the faster rate of axial elongation.

Polish Researchers Invent Anti-smog Sound Cannon

Published

“We use vertical shock waves generated by the combustion of acetylene and air,” says Dominique Grivos on the right.

In the constant fight against Poland’s smog, scientists are experimenting with new “cannons” that use sound waves to push toxic particles into the atmosphere, allowing residents to breathe.

The experimental device sits on a metal container and consists of a large upside-down cone that makes a loud noise every 6 seconds.

The purpose is to track smog From Kalwaria Zebrzydowska, where the inhabitants face problems every winter in a heavily polluted state, like many Polish towns and cities. Heating system..

When the sun goes down, the chimneys spew out thick smoke, causing heavy smog to fall into the town.

Poland is one of the most polluted countries in Europe, violating EU standards by hundreds of percentage points at the worst of the year.

By creating sound waves, researchers can “Cannon“Helps reduce the concentration of harmful PM2.5 and PM10 particles in the town air.

“We use vertical shock waves generated by the burning of acetylene and air,” said Dominik Grybos of the Mining and Metallurgy Academy in Krakow, one of the inventors.

“The waves are Polluted air Higher, “he told AFP.

The Toxic particles It is sent hundreds of meters (yards) high and is harmless to the inhabitants.

The experimental sound “cannon”, as described by Polish researchers, can blow toxic particles into the sky hundreds of meters.

“We found that using the cannon for 30 minutes to an hour reduced pollution by 15-30% within a range of 2-3 km (1.2-1.9 miles) from the cannon,” says Grybos. He adds that the effect lasts “between 1 and 3 hours.”

Researchers are trying to calculate the required frequency of blast waves and the duration and time required for the entire procedure.

The price is estimated to be 1,000 to 1,500 zloty ($ 250 to $ 375) for one hour of use.

Mr. Grivos said he hopes that the invention will find commercial use, especially in Poland.

Residents of Kalwaria Zebrzydowska are in widespread support for this idea, despite the sound.

“The smog is very heavy here. The smell is so bad that I can’t deflate the apartment. If that helps, let them test,” said 43-year-old accountant Joranta Warkowich.

“I can hardly hear the sound. It’s like a fireworks display,” she added.
