A compact low-profile phased array antenna unit with unidirectional hemispherical beam-coverage for 5G mm-wave applications is proposed in this paper.A four-subarray configuration is used for the proposed structure to achieve unidirectional hemispherical coverage in the boresight direction normal to the substrate.An artificial magnetic conductor (A
Lack of iron leads to a weakening of plant growth and lower yields.A gtech brush bar promising solution to this problem is the use of nanoparticles of iron, iron oxides as biostimulators of growth of agricultural plants.However, the special properties of nanoparticles can enhance the mechanisms associated with toxic effects on living organisms, lea
Collections of biological specimens are fundamental to scientific understanding and characterization of natural diversity-past, present and future.This paper presents a system for liberating useful information from physical collections by bringing specimens into the digital domain so they can be more readily shared, analyzed, annotated and compared
