The AlN/GaN/AlN heterostructure is attractive for microwave and millimeter-wave power devices due to its thin top barrier, tight carrier confinement, improved breakdown voltage. This work explores the large-signal RF performance of high-electron-mobility transistors on this heterostructure. Results are highlighted by record high on-current 3.6 A/mm, maximum oscillation frequency (f <sub xmlns:m...

objectives: this study sought to assess the effects of length and inclination of implants on stress distribution in an implant and terminal abutment teeth in an implant assisted-removable partial denture (rpd) using three-dimensional (3d) finite element analysis (fea).   materials and methods: in this in vitro study, a 3d finite element model of a partially dentate mandible with a distal extens...

Induction of triploidy is one of the biotechnological methods in aquaculture used for genetic manipulation. It refers to a state where organisms have three complete sets of chromosomes instead of two and can result in sterility. Caffeine treatment that is safe and inexpensive, serve to induce triploidy in catfish. To suppress the second meiotic division, fertilized eggs were exposed to three di...

glasswort(salicornia europaea l.) as an important halophyte plant is capable to accumulate nacl in aboveground part (fully edible) in considerable quantity. to evaluate the effect of irrigation levels and nitrogen fertilizer on the yield of seed and oil, and also harvest index of glasswort, a split plot experiment was conducted based on randomized complete block design with three replications a...
