Local magnitude (M) scales have been developed for Egypt based on 14,453 normalized Wood-Anderson amplitudes from 1670 earthquakes. These events were recorded by at least four seismic stations, with hypocentral depths of less than 40 km and earthquake magnitudes ranging from 0.1 to 6.

Nails are commonly associated with a greater severity of the disease. Radiofrequency (RF) is a nonionizing radiation that provides energy originating from electric current to generate heat inside the dermis with anti-inflammatory effects.

Materials & Methods: A new series of bis-1,4-disubstituted-1,2,3-triazoles moieties conjugated with a 2-mercapto-benzimidazole 4a-h and 7a-g was synthesized via the click cycloaddition (CuAAC) reaction.
Article Synopsis
- The paper introduces a novel metamaterial absorber design using a bent Y-shaped structure on an FR-4 substrate with copper, achieving over 90% absorption across a range of frequencies from L-band to K-band (3.728 GHz to 22.664 GHz).
- Through simulations, it identifies eight resonant frequencies, highlighting the design's versatility for reducing electromagnetic radiation.
- Additionally, the research discusses the implications of near-zero refractive index metamaterials and their potential for advanced wave control, emphasizing the absorber's polarization insensitivity and unique electromagnetic properties that challenge existing theories.
Purpose: To evaluate the outcomes of pars plana vitrectomy (PPV) for full thickness macular holes (FTMH) in ocular Behçet's disease.
Methods: Eyes with FTMH as confirmed on optical coherence tomography in patients with active ocular Behçet's disease (AOBD) were included in this study. These eyes underwent PPV, epiretinal membrane (ERM) removal, internal limiting membrane (ILM) peel, and a tamponade injection.
