CONTROL OF SECRETION OF PARATHYROID HORMONE IN SECONDARY HYPERPARATHYROIDISM
Clinical Endocrinology, 1982The response of the parathyroids to an infusion of calcium has been studied in patients with secondary hyperparathyroidism due to either vitamin D deficiency or to chronic renal failure. Two specific homologous immunoradiometric assays for human parathyroid hormone (PTH) have been used to assess the response, one specific for the amino‐terminus (N‐PTH),

THE SECONDARY VOLTAGE CONTROL OF EDF NETWORK
IFAC Proceedings Volumes, 1980Abstract The “secondary voltage control” is a regionalized voltage regulation method. It has been experimented, in the Paris area, during the last few years. It is now extended to the whole French EHV network.

Secondary Control in AC Microgrids - Challenges and Solutions
Proceedings of the 4th International Conference on Smart Cities and Green ICT Systems, 2015The hierarchical control structure of a microgrid can be described as consisting of four levels: processing, sensing and adjusting, monitoring and supervising, and maintenance and optimizing. This paper focuses on the secondary control level, which can be classified as centralized or decentralized control.

Secondary Control In Subsea Mining
Offshore Technology Conference, 2020Subsea mining increasingly plays an important role in the extraction of raw materials. The decentral automation is the next generation of this technology. The conventional hydraulic drive systems were not able to fulfil the requirements of slow speed parallel drive operation of the chain drives of the vehicle with a sufficient result.

Secondary voltage and stability control
2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012Secondary voltage controls, as a non-cost voltage control, are often conducted by utilities as the first option to solve voltage violations. Utilities like PJM and MISO manually coordinate secondary voltage controls aiming at regulating voltage profile and avoiding the use of potentially costly controls, such as transmission loading relief or load ...

Secondary Control for Islanded Microgrids
2018This chapter introduces concepts, characteristics, advantages, and drawbacks of different secondary control approaches for islanded microgrids. First, multilayer hierarchical control is reviewed, defining the main features and control objectives of each control layer.

Control of Secondary Pests, 1988
Insecticide and Acaricide Tests, 1989Abstract Cotton was planted 15 Apr at the Texas Agricultural Experiment Station annex farm in Mercedes. The experimental design was a randomized complete block with 5 replicates. Plots were 2 beds wide and 40 ft long with 2 beds of sorghum between plots and 20-ft alleys between plots in rows. Applications were made with a tractor-mounted

Secondary Control Technology and Applications
Fluid Power Systems and Technology, 1998Abstract Secondary control is the definition for a variable displacement rotary hydrostatic drive working with constant pressure. The controlling element of the system is the swivel angle of the hydraulic drive, normally an axial piston unit.
