Advantages and Disadvantages of Spring Seeding
1. Put the seeds in clean water, the full seed particles sink, while the sorghum seeds, diseased seeds and sclerotia float on the water. Simply picking up the floating seeds will achieve the purpose of selection.
2. Hot water bath Generally, rice seeds are immersed in hot water at 50 ° C ~ 54 ° C for 10 minutes; cotton seeds with thick skin should be immersed in hot water at 50 ° C ~ 60 ° C for 30 minutes.
3, the salt water bath into the salt water, using the characteristics of salt water to force the inferior species to surface.
4. The medicated water bath adds trisodium phosphate, sodium hydroxide, potassium permanganate and other drugs to the water, which can not only play a selection role, but also kill the bacteria.
5, the hormone bath with the help of Zhuangsu, paclobutrazol, chlormequat and other solutions soaking seeds, can make the seedlings robust, complete emergence. In addition, seed coating with a coating agent can not only improve the disease resistance of the seed, but also promote seed fertility.

Hearing aid manufacturers strive to optimize their wireless hearing aid offerings both in terms of connection reliability as well as power efficiency. Variance across patients and listening conditions can make optimizing wireless hearing aid systems a complex process.
Factors such as connection distance, proximity of reflective surfaces, interference from other wireless devices, and energy loss through body absorption must all be factored into the hearing aid design. For example, indoor wireless performance may be very different from wireless performance experienced outdoors, where the only reflective surface may be the ground on which the hearing aid user is standing. Furthermore, individual differences in body geometry increase the variability that wireless engineers must account for when designing a system that provides each user with a consistent and reliable experience.
As awareness of wireless hearing technology grows, hearing healthcare professionals may notice an uptick in long-term safety concerns. Consumers should be confident knowing that wireless hearing aids are safe and strictly regulated medical devices that meet governmental wireless communication standards in addition to those set forth for medical devices.
