SDMA

(Spatial Division Multiple Access) A satellite communications method that transmits within the same frequency to different receiving zones on earth. It takes advantage of the narrow beams that can be transmitted by the satellite to dish antennas and allows channels (frequencies) to be reused over a large number of geographic zones. Contrast with FDMA and TDMA.

The SDMA officials also asked the people to coordinate with the emergency control room (058-21921643) which had been established in Muzaffarabad to facilitate the rescue operation.
Therefore, ZF SDMA solution eliminates the interference from the received signal that is transferred from any other users in the transmitter side.
On this background, we hypothesized that ADMA and SDMA levels might be predictive of the cardiovascular risk, all-cause mortality, and renal function of patients with anti-neutrophil-cytoplasmic antibodies (ANCA)-associated small vessel vasculitis (AASV) subjected to well-defined treatment regimens in four European Vasculitis Study Group (EUVAS) trials.
On the contrary, SP transmit-array and one collocated DP transmit-antenna increase performance by SDMA and polarization division multiple access (PDMA) respectively.
The SDMA increases with both acute and active kidney injury and chronic disease, allowing vets to intervene earlier for more successful outcomes," said Atieh.
Recently, a new technique for the routine detection of canine SDMA, namely, the IDEXX SDMA[R] test, has been developed and validated [24], and interpretation of SDMA concentrations has been included in the International Renal Interest Society (IRIS) CKD staging guidelines [25].
Regarding the analysis of L-arginine, ADMA, and SDMA in human plasma, sample preparation by SPE using cation-exchange columns is the currently preferred approach [10-13].
In this section, the comparative descriptions of space division multiple access (SDMA), polarization division multiple access (PDMA), and SPDMA techniques are presented.
The first methylation leads to the formation of monomethylarginine (MMA), while the second one can produce either symmetric dimethylarginine (SDMA) or ADMA, according to the PRMT isoform involved in the methylation reaction [14].
Both technologies implement Space Division Multiple Access (SDMA).
In order to obtain plasma for determination sP-selectin, PF4, L-arginine, ADMA, and SDMA in the second part of the experiment, blood was collected in the Sarstedt S-Monovette (1.6 mg EDTA/ml blood) tube and within 30 minutes after the collection, it was centrifuged at 1000 xg for 15 min at 4[degrees]C and stored at -20[degrees]C until analysis.
(ii) Metabolites of the NO pathway (asymmetrical dimethylarginine (ADMA), symmetrical dimethylarginine (SDMA), and L-arginine).
