All extractions included a negative extraction control where buffer only was extracted in parallel with specimens.
Both water controls and an extraction control consisting of a mammoth DNA extract were negative for cave bear-specific products.
We processed one negative extraction control for each six fossil samples extracted (total of 28 blank extraction controls) and followed these samples through PCR amplification.
Similarly, three types of PCR-negative controls were also processed in each set of assays: (i) an extraction control (with all the steps but without any extracted material), (ii) a reaction tube with substitution of Qiagen RNase free-water for the test template (iii) a negative sample from previous PCR assay.
Total RNA was extracted from swine clinical specimens (above) as previously described, including a positive extraction control that was prepared to yield a pre-determined Ct value [33].
The hydro-viscous transmission based maximum power extraction control is presented in this paper.
The system model and the maximum power extraction control loop are also presented and designed.
This paper introduces the injection and extraction control system design for SSRF, which is a distributed control system aimed at stability and reliability of the pulse power supplies, PPS (Personnel Protection System) and MPS (Machine Protection System).
Future schemes for plant extraction, control of water efflux by increasing evapotranspiration, and by subsequent land use with agricultural plants with biostabilization and phytosequestration potential will provide putative control measures.
Exposure of COCs to the metabolised mixture induced a decrease of apoptotic cumulus cells at low concentrations and an increase at higher concentrations following a U-shaped curve (p = 0.0106), with the intermediate treatment (3.6 μg/l OH-PCBs) significantly reducing apoptosis compared to the extraction control (p = 0.05).
The advantages of using ultrasound for food processing, includes: more effective mixing and micro-mixing, faster energy and mass transfer, reduced thermal and concentration gradients, reduced temperature, selective extraction, reduced equipment size, faster response to process extraction control, faster start-up, increased production, and elimination of process steps.
