A Microwave Differential Dielectric Sensor Based on Mode Splitting of Coupled Resonators.

This study explores the viability of using the avoided mode crossing phenomenon in the microwave regime to design microwave differential sensors. While the design concept can be applied to any type of planar electrically small resonators, here, it is implemented on split-ring resonators (SRRs). We use two coupled synchronous SRRs loaded onto a two-port microstrip line system to demonstrate the avoided mode crossing by varying the distance between the split of the resonators to control the coupling strength.

Digital technologies in dentistry in Saudi Arabia: Perceptions, practices and challenges.

Background: The aim of this study was to assess practicing dentists' characteristics and professional aspects that influence users to adopt Digital Technologies in Dentistry (DTD) in Saudi Arabia (SA). Moreover, we aimed to identify dentists' perceived barriers and challenges and to anticipate future potential developments towards implementing DTDs in their practices in SA.

Methods: This analytical cross-sectional study based on a validated questionnaire was conducted using a snowball sampling technique to include a conveniently selected sample of dentists from all dental specialties currently working in SA.

Protective role of iron oxide nanocomposites on disease index, and biochemical resistance indicators against Fusarium oxysporum induced-cucumber wilt disease: In vitro, and in vivo studies.

Recently nanocomposites have become a super-growth inducers as well as vital antifungal agents, which enhance plant growth and suppress plant diseases. A new strategy regarding the fabrication of humic acid (H) and boron (B) conjugated FeO nanocomposites was performed. FeO NP-B and FeO NP-H were synthesized in the presence of gamma-rays (as a direct reducing agent).
