High isolation MIMO antenna for high speed communication
2014 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium), 2014Ubiquitous use of handheld devices has put a tremendous strain on the available bandwidth of communication. The scarcity of spectrum has rapidly shifted the modern systems towards multiple input and multiple output systems (MIMO). The development of MIMO antennas has attracted significant attention in literature.

Isolation and properties of high molecular weight heparin
Thrombosis Research, 1981Abstract A heparin fraction comprising the highest molecular weight components of beef-lung heparin preparations was isolated by chromatography on Biogel P-100. This fraction, all of which is highly active in accelerating the inhibition of thrombin by antithrombin III, includes material with considerably greater activities than previously reported ...

Testing and Isolation of High-Purity Restriction Endonucleases
Applied Biochemistry and Microbiology, 2002A new method of testing restriction nucleases is proposed. This method is based on high-temperature treatment of crude cell extracts. Disrupted cells were heated at 50-60 degrees C, centrifuged, and assayed for restrictases. This method provides the opportunity for screening new enzymes in microbial strains enriched with nonspecific restrictases.

Structure-Shared Planar UWB MIMO Antenna With High Isolation for Mobile Platform
IEEE Transactions on Antennas and Propagation, 2019A two-port structure-shared planar ultrawideband (UWB) antenna with high isolation is presented in this communication. The proposed antenna consists of a planar monopole and two back-to-back tapered slots etched on the monopole.

Autolysis of high-GC isolates of Pseudomonas putrefaciens
Antonie van Leeuwenhoek, 1976High-GC isolates of P. putrefaciens undergo extensive autolysis after growth, resulting in a marked decrease in turbidity and the release of high-molecular-weight DNA which imparts a high viscosity to culture broths. The native DNA released is resistant to attack by the exocellular DNase activity of the culture broths. Autolysis is inhibited by a pH of

Isolation of high quality RNA from Streptomyces
Journal of Microbiological Methods, 2004Several molecular techniques require high quality RNA, completely free of DNA. Standard methods to isolate total RNA from Streptomyces spp. are based on the application of a 'Modified Kirby Mix' [Practical Streptomyces Genetics. The John Innes Foundation, Norwich, pp. 613].
