Researchers found proteins that distinguish sound
According to a Reuters report, French researchers have recently seen that one kind of inner ear protein can help people distinguish voices and understand conversations. The fruit of this research can help solve the problem of hearing impairment.
French researcher Paul Awang said that this 1 can not be used to treat deafness, but it helps to explain why some people will flash hearing impairment, especially in noisy environments.
The researchers conducted experiments on genetically modified mice to study the cochlea of ​​the inner ear. The cochlea contains two types of nerve cells that recognize sound. I feel that the "ion channels" inside nerve cells are important to the mission of "sound distortion" in the inner ear. The use of ion channels is similar to that of microphones, which can convert sound into electronic information and transmit it to the brain. The link of sound distortion is very important, which enables people to distinguish the required sound from the mixed noise.
The researchers saw that it is not the ion channels that maintain the nerve cells that are not destroyed, but a protein called sclerostin, which can properly distort the sound of the inner ear.
Awang and his colleagues published a research report in the "Nature" weekly magazine that mice lacking sclerostin still have hearing impairments even when the ion channels are working properly.
Packing Tape is made from varied materials using many different adhesives to adhere to containers. The most used packaging tapes are made from polypropylene with an acrylic adhesive.
Packing Tape is an important part of any packaging operation Adhesive Tape . Companies using boxes, envelopes, or any other containers for packaging normally use tape for sealing. Tapes specifically made for packaging come in a variety of lengths, colors, and widths. They also vary in materials and adhesives they are made from.
Below is a brief explanation of the types of packing tapes that we offer and what they are recommended to be used for.

Here are a few packing tape terms about tape, which are important for resolving tape and using tape.
Abrasion Resistance – The ability of a tape to withstand scuffing, scraping, and rubbing against other surfaces.
Elongation – The distance a tape can stretch lengthways without breaking.
Tensile Strength – The force often measured in pounds to break a piece of tape by pulling each side in opposite directions.
High-Speed Unwind – The practice of dispensing tape at speeds in excess of 15 meters per minute.
Hot Melt Adhesive – A pressure sensitive adhesive applied in liquid form.
Shock Resistance – The ability of a tape to resist sudden shocks throughout transport. Shocks can be falls, crushing, pulls, and more.
Peel Adhesion – The force required to remove a tape from the surface it has been applied.
Backing Material – The backing material is the material the chosen adhesive is applied to. A variety of backing materials are used in tape manufacturing including films, paper, and foam.
