In this study, balanced and single ended class-E power amplifiers (PAs) were designed and realized for 3.5–3.8GHz band by using Gallium Nitride high electron mobility transistor (GaN HEMT). Realizations were made on low loss Rogers RT5880 dielectric material which has 0.254mm thickness and 2.2 dielectric constant. Proposed balanced class-E PA has approximately 20W (43 dBm) output power with 80%...

Red pigments with bright colors were widely used in ancient Chinese painted pottery, books, antiques, calligraphy, and paintings. Herein, red of traditional paper notes investigated by non-invasive optical technology order to enrich the historical knowledge base. The results laser Raman spectroscopy tests on five clearly identified inorganic mineral including ocher cinnabar. Infrared measuremen...

Background: the inappropriate use of handouts and notes is a common academic problem among students. Students' notes are too brief and incomplete in compare with references; hence they may not cover the required content for the courses. The aim of this paper is to analyze students' attitude toward reading handouts and notes instead of references. Methods: In this analytical and descriptive stud...
