Four months for DNA results, still waiting. I had a DNA kit sent to my BIL for his birthday in August. He spit, sent it off, and 10 weeks later was informed that it didn't work so they sent him a new kit.It has now been 9 weeks since the lab received his second spit, no results.our months for DNA results, still waiting.

Code division multiple access (CDMA) is a channel access method used by various radio communication technologies.CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel.This allows several users to share a band of frequencies (see bandwidth).DMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel.

A wave with that wavelength would have a frequency of $\approx 6.2\cdot 10^{34}\,\text{Hz}$. A gamma ray typically has a frequency of $>10^{19}\,\text{Hz}$. Since the energy of a photon is directly proportional to its frequency, this theoretical upper bound would require vastly more energetic processes than those we presently conceive of.
