Effect of sulcular green tea extract irrigation on experimental rabbit’s gingivitis (A histopathological study)
...Show More Authors

Background: Considering the antioxidant, anti-inflammatory, and antimicrobial properties of green tea, this study aimed to evaluate the histopathological effect of the sulcular irrigation of green tea extract in the treatment of experimental gingivitis in rabbit.

Materials and methods: For this experimental study, 45 male rabbits, separated in two groups, control non- irrigated group (5rabbits) and study group (40 rabbits), gingivitis induced by ligatures was packed subgingivally in the lower right central incisors of the experimental group for seven days. Then, the animals were randomly designated to two irrigated groups (20 rabbits for each) with 50µl/kg of distilled water and 5% green tea extract once daily for seven days starting from the day of ligature removal respectively. Specimens have taken at 1, 3, 7, and 14 days for light microscopical evaluation of inflammatory cellular infiltration.

Results: Regarding study group (5% of green tea extract), results demonstrated a significant reduction in the mean values of inflammatory cell counts within three days (P≤ 0.05) to reach the amount of control group within seven days (P˃ 0.05). A highly significant difference was detected between control group and study group sprayed with distilled water during all healing periods (P≤ 0.05). Histological examination showed that the resolution of gingival inflammation, re-epithelization, and tissue healing were achieved much quicker in the group of gingival sulcular irrigation with 5% green tea extract.

Conclusions: In this experimental study, the histopathological analysis demonstrated that the use of 5% extract of green tea as gingival sulcular irrigation might fasten healing after the induction of gingivitis.

Keywords: green tea, animal model, gingival sulcular irrigation, experimental gingivitis.

Design Investigation of 2 × 2 Mach–Zehnder Optical Switch Based on a Metal–Polymer–Silicon Hybrid Plasmonic Waveguide
...Show More Authors

In this paper, a miniaturized 2 × 2 electro-optic plasmonic Mach– Zehnder switch (MZS) based on metal–polymer–silicon hybrid waveguide is presented. Adiabatic tapers are designed to couple the light between the plasmonic phase shifter, implemented in each of the MZS arms, and the 3-dB input/output directional couplers. For 6 µm-long hybrid plasmonic waveguide supported by JRD1 polymer (r33= 390 pm/V), a π-phase shift voltage of 2 V is obtained. The switch is designed for 1550 nm operation wavelength using COMSOL software and characterizes by 2.3 dB insertion loss, 9.9 fJ/bit power consumption, and 640 GHz operation bandwidth

Design of a Kinematic Neural Controller for Mobile Robots based on Enhanced Hybrid Firefly-Artificial Bee Colony Algorithm
...Show More Authors

The paper present design of a control structure that enables integration of a Kinematic neural controller for trajectory tracking of a nonholonomic differential two wheeled mobile robot, then  proposes a Kinematic neural controller to direct a National Instrument mobile robot (NI Mobile Robot). The controller is to make the actual velocity of the wheeled mobile robot close the required velocity by guarantees that the trajectory tracking mean squire error converges at minimum tracking error. The proposed tracking control system consists of two layers; The first layer is a multi-layer perceptron neural network system that controls the mobile robot to track the required path , The second layer is an optimization layer ,which is impleme

This research reviews the aesthetic variables that were founded according to (theatrical rehearsal) as one of the most important pillars on which the theatrical process is based, because of its necessity in developing theatrical art on several levels that helped the theatrical director in organizing his work, and this became clear through the research chapters represented in the first chapter (methodological framework) and the second chapter, which consisted of the first topic (the duality of watching / rehearsal) and the second topic (the applications of theatrical rehearsal in theatrical experiences), all the way to the third chapter (research procedures), which included the analysis of theatrical rehearsals (sharing on life), and the
