Functions and strategies for enhancing zinc availability in plants for sustainable agriculture
( Frontiers Media , 2022 , Article Review)Zinc (Zn), which is regarded as a crucial micronutrient for plants, and is considered to be a vital micronutrient for plants. Zn has a significant role in the biochemistry and metabolism of plants owing to its significance ... -
Functions Near Of Na-Continuity
( Qatar University , 1989 , Article)In 1986, the concept of Na-continuity was initiated by Chae et al., this leads us to introduce two classes of functions, namely strongly Na-continuity and weakly Na-continuity. We characterize these new types. Several ... -
Fundamental group and cycle space of dual graphs and applications
( Elsevier , 2010 , Article)In this work, we study the fundamental group of dual graph of a planar graph. Moreover, we show that a planar graph G has no cut vertex if and only if N(Π(D(G))) = N(Π(D(G − v))) − 1 for any v ∈ V(G). Some applications ... -
Fundamental output voltage enhancement of half-bridge voltage source inverter with low DC-link capacitance
( Korean Institute of Power Electronics , 2018 , Article)Conventionally, in order to reduce the ac components of the dc-link capacitors of the two-level Half-Bridge Voltage Source Inverter (HB-VSI), high dc-link capacitances are required. This necessitates the employment of ... -
