Radar observations of field-aligned plasma propagations associated with NASA's PMG experiment
ASA's Plasma Motor Generator (PMG) tethered satellite mission was launched in June 1993 to verify the ability of hollow cathode plasma sources to couple electric currents from an electrodynamic tether into the ambient ionospheric plasma. This large-scale coupling process resulted in turbulent …

Unified Control for the Permanent Magnet Generator and Rectifier System
The structure of a permanent magnet generator (PMG) connected with an active front-end rectifier is very popular in the AC-DC architecture. Especially for certain applications like aircraft and vehicles, power density and efficiency is critical. Since the generator and the rectifier can be …

Inhibition of Mycelial Growth and Reproduction of Phytophthora Megasperma F. Sp. Glycinea by Trichothecin Produced by Trichothecium Roseum
… and Phytophthora megasperma f. sp. glycinea (Pmg) was studied. Culture filtrates of T. roseum inhibited mycelial growth as well as zoosporangenesis of Pmg in culture and soil, but not those of G. roseum and T. harzianum. The antagonism by culture filtrates of T. roseum was found to be due to …

Is Sub-Saharan Africa likely to yield demographic dividends in the 21st century?
… and trade openness. The Pooled Mean Group (PMG) and the two-step difference Generalised Method of Moments (GMM) were used to predict the relationship amongst the dependent and independent variables. The main findings of the study using PMG estimation are that: (i) there is a negative …

Integration of VHDL simulation and test verification into a Process Model Graph design environment
… environment by use of the Process Model Graph (PMG) throughout the development process. This ability extends the functionality of the PMG to include the visualization of simulation results and the verification of test paths within the simulation. These ideas have been implemented within a …

Model based approach to Hardware/ Software Partitioning of SOC Designs
… on systems modeled using Process Model Graphs (PmG). It is possible to extract a PmG directly from a SLML like SystemC. The PmG is then annotated with additional attributes like IO delay and rate of activation. A complexity heuristic is generated from this information, which is then used by a …

Interaction between Phytophthora megasperma f. sp. glycinea and Glycine max
… Phytophthora megasperma f. sp. glycinea (Pmg) pathosystem has served as a model for elucidating the mechansim of incompatibility in gene-for-gene interactions. This interaction was accurately and precisely investigated on the taproots of aeroponically-grown soybeans. An aeroponics system, …

Comparative studies on the modes of action of SC-0224 and glyphosate
… and glyphosate [N-(phosphonomethyl)glycine] (PMG) were compared. In each study trimethylsulfonium iodide (TMS-I) was included as a treatment because the trimethylsulfonium ion is a constituent of the SC-0224 molecular structure. In inflated duckweed (Lemna gibba L.), both formulated and …

Nuclear magnetic resonance studies of boron trihalide complexes of 1,1-BIS (dimethylamino) ethylene and related bases
… (TMG) , and pentamethylguanidine (PMG) and also mixed boron t r ihalide adducts of DME have been investigated by 1H and 19F NMR spectroscopy. Both nitrogen and the C-Q-H carbon of DME are possible donor a toms to boron trihal ides but complexation has been found to occur only at …

The impact of green finance, renewable energy, and economic growth on energy transition in African countries
… African countries. The study employed a panel PMG-ARDL approach, over the period 2000 – 2019. The findings indicate that in the long run, renewable energy has a negative impact on carbon dioxide emissions, whereas green finance and economic growth positively impact carbon dioxide emissions. …

Generation of VHDL from conceptual graphs of informal specifications
… conceptual graphs into Process Model Graphs (PMGs) and corresponding VHDL code. Once a PMG (and associated VHDL code) has been created it can be edited as needed on the Modeler's Assistant, to fill in any holes left by the interpreters, correct errors, expand the model, or make it more …
