This work presents a novel design model of magnetorheological (MR) fluid-based shock absorber (MR in short) that can be applied to an aircraft landing gear system. When external force acts on MR absorber, pressure loss occurs at the flow path while resisting fluid flow. During motion, two losses occur: major loss, which is proportional rate, and minor square rate. In general, when designed for ...

Magnetorheological (MR) fluids with Fe3O4 particles are widely studied nowadays due to their soft magnetic nature, controllable morphology, and better chemical stability as compared metallic counterpart. However, they can be even more advantageous under Zn doping elevated magnetization hollow configuration low density, making them active, stable, dispersible in the carrier fluid. Here, we repor...

Abstract The study experimentally examines the quasi-static shear deformation of a magnetorheological (MR) fluid structured in an external magnetic field. Experiments are carried out using rheometer with plate–plate configuration. working surfaces measuring geometry modified to demonstrate their influence on response field-structured MR fluid. simplest possible suspension microparticles carbony...

Peliosis is a rare benign disorder that is characterized by the presence of diffuse blood-filled cystic spaces and can occur in the liver, spleen, bone-marrow, and lungs. We present a 10-year-old boy with Fanconi anemia who presented with peliosis hepatis due to androgen treatment. Magnetic resonance (MR) imaging revealed multiple non-enhancing masses. Some of the lesions revealed fluid-fluid l...

PURPOSE To determine the sensitivity of contrast MR versus myelography followed by CT in the detection of cerebrospinal fluid metastases in children with primary central nervous system tumors. METHODS Thirty-three patients who had primary central nervous system malignancies had spinal MR with gadolinium within 2 weeks of a myelogram followed by CT. MR technique included T1-weighted image sequ...

In this research work, two different compositions of MR fluid samples with 24 and 30 percentage (%) volume fraction carbonyl iron (CI) particles are prepared. Prepared (MRF) contain as a dispersive medium, silicone oil carrier fluid, white lithium grease an anti-settling agent. Influence oscillating driving frequency, strain amplitude, magnetic field, the CI particle on rheological properties p...

Fluid jet machining has been widely used in of hard-brittle materials. However, the diffusion a flow significantly affects erosion capacity. Magnetorheological (MR) fluid considered to take role pure water for carrying abrasive particles, due its better concentration when external magnetic field is applied. The present investigation focuses on characteristics magnetorheological jet, which are i...

Magnetorheological (MR) dampers have received a great deal of attention due to their being a potential technology to conduct semi-active vibration control and it has become vitally important to describe the dynamic responses of these devices in an effective manner in order to develop successful control algorithms. To this end, a considerable effort has been devoted in the literature to study th...

PURPOSE To describe the gadolinium-enhanced MR findings of Rathke cleft cyst correlate them with the surgical findings, and define those preoperative findings that differentiate this lesion from other sellar and juxtasellar tumors. METHODS We studied 18 patients who were diagnosed as having Rathke cleft cyst pathologically. These patients were imaged with T1- and T2-weighted coronal and sagit...

Introduction: Bacterial meningitis is an acute infectious inflammation of the protective membranes covering the brain. Its early diagnosis is vital because of its high morbidity and mortality. It is mostly diagnosed by a gold standard diagnostic tool i.e. Cerebrospinal Fluid (CSF) analysis. However, it is sometimes difficult and or impossible to do this procedure and an alternative diagnostic t...
