The current study explores the representation of maternal authority and its intersection with structuralist dynamics and socio-economic struggles in Clifford Odets’ Awake and Sing! through the character of Bessie Berger. Positioned as the central force within the Berger household, Bessie embodies a maternal figure whose dominance has a negative impact on the relationship with her children by using them as tools to fulfill her dreams. By applying a structuralism, alongside an analysis of maternal authority and social struggles, the study examines the binary oppositions of control versus freedom and materialism versus idealism, highlighting the tensions between Bessie’s authority pursuit of financial stability and the aspirations of he

his paper uses the finite element method (FEM) to study a Surface Plasmon Resonance (SPR) refractive index sensor based on D-shaped Polarization Maintain Photonic Crystal Fiber (PM-PCF). A chemically stable plasmonic material, gold (Au), with hemispherical structures having a radius of 50 nm, is applied to the surface of a D-shaped sensor to create the surface plasmon resonance (SPR) effect, enabling this SPR sensor to detect variation in the surrounding analyte refractive index (RI). The resonance condition will change when the refractive index of the targeted analyte changes, leading to a certain shift in the loss peak. Two resonant peaks are observed, one located in the visible part of the spectrum, and the second in the near-infrared

  COVID-19 disease is a clinical syndrome caused by an envelope RNA virus, called SARS-COV-2., which causes infection with wildly clinical pictures. Through COVID-19 infection several components of humoral and cellular immune response have an important role in the progression of the infection. Chemokines are one of the inflammatory mediators that play an essential role in the immune pathogenesis of COVID-19. It is secreted by respiratory virus-infected cells in the upper respiratory tract, causing stimulation and recruitment of inflammatory cells such as neutrophils, NK, eosinophils, and macrophages from the bloodstream to the site of the infection. This study strives to determine the impact role of inflammatory mediat

The exact mechanism of action and which rheumatoid arthritis (RA) patients might benefit from Rituximab (RTX) are still questionable. One of the key elements in assessing the performance of a healthcare facility is patient satisfaction, which is a measure of how satisfied a patient is with the medical care he receives. This study aimed to evaluate the health-related quality of life and treatment satisfaction and their association with the responsiveness to RTX in RA patients. A cross-sectional study was conducted at the Center of Rheumatology in Baghdad- Iraq. The study enrolled 90 patients diagnosed with RA and receiving RTX intravenous infusion, for at least six months.
