Operating partial core transformers under liquid nitrogen conditions

Structure and dynamics of liquid iron under Earth’s core conditions

First-principles molecular-dynamics simulations based on density-functional theory and the projector augmented wave ~PAW! technique have been used to study the structural and dynamical properties of liquid iron under Earth’s core conditions. As evidence for the accuracy of the techniques, we present PAW results for a range of solid-state properties of lowand high-pressure iron, and compare them...

Performance of Photovoltaics Under Actual Operating Conditions

Nonlinear Model of Tape Wound Core Transformers

Recently, tape wound cores due to their excellent magnetic properties, are widely used in different types of transformers. Performance prediction of these transformers needs an accurate model with ability to determine flux distribution within the core and magnetic loss. Spiral structure of tape wound cores affects the flux distribution and always cause complication of analysis. In this paper, a...

Yield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation

Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...

Physiological Response of Quinoa to Nitrogen Application under Salinity Conditions

Salinity stress is one of the major abiotic stresses which injures plants by limited water absorption and nutrient imbalance and limits crop growth. In order to study the effect of nitrogen fertilizer on physiological traits of quinoa at high salt concentrations, a greenhouse experiment was conducted in a factorial arrangement based on a randomized complete block with three replications in 2019...
