Cryogels, generated by freezing a reactive polymerization mixture, offer versatility and cost-effectiveness as macroporous, polymeric, monolithic adsorbents. The conversion of cryogels into affinity adsorbents, particularly using epoxy radicals as supports, provides a promising alternative for biomolecule purification.

Summary: Site diversity is an effective method to recover signal loss in heavy downpours, especially in tropical regions. Duplicated links at diverse sites are used to route the least-attenuated signal to the prime site. Factors such as site-separation distance, elevation angle, baseline angle, and signal frequency determine the diversity gain, while the impact of rain-cell span and wind on the gain is still under investigation.
