Hall effect thrusters are yet not fully understood due to multiple open questions, among which the anomalous electron transport is most challenging. Particle-In-Cell (PIC) simulations suggested that strongly affected by small-scale instabilities can be investigated experimentally using Collective Thomson Scattering (CTS). In this paper, we perform a virtual CTS diagnostic on PIC data in order i...

ABSTRACT Here, we report the new detection of three shock fronts using archival Chandra X-ray observations in Abell 1914, which also hosts a radio halo, phoenix, and head–tail galaxy. In this study, front at position further strengthens scenario that phoenix traces old plasma gets lit up when compressed by passage. We analyse thermodynamic structure cluster detail. create temperature maps A1914...

The critical role played by adhesive bonds in lap joints is well known. A good knowledge of the mechanical properties of adhesive bonds in lap joints is a prerequisite to the design and reliable prediction of the performance of these bonded structures. Furthermore, the lap joint may be subject to high-temperature environments in service. Early detection of the degree of thermal degradation in a...

trabeculectomy is the most common procedure performed in glaucoma patients to reduce intraocular pressure for a long-time period. this intervention can cause alterations in axial length (0.1-0.9 mm), anterior chamber depth (0.11±0.22 mm), and keratometry readings (1.07±1.14 diopter). these changes may linger for more than one year and may negatively affect the precision of intraocular lens powe...

this study was conducted to define the prevalence and types of corneal astigmatism in relation with corneal optical power, axial length, sex and patient age. 641 cataract patients were included in a descriptive study. complete eye examinations were included in a descriptive study. complete eye examinations were performed. the data were analysed by standard procedures including analysis of varia...

the load transfer mechanisms of cable bolts differ from those for normal rebar bolts. the cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. the tendon strength can be evaluated by the tensi...

in this paper the meshless local petrov-galerkin (mlpg) method is implemented to study the buckling of isotropic cylindrical shells under axial load. displacement field equations, based on donnell and first order shear deformation theory, are taken into consideration. the set of governing equations of motion are numerically solved by the mlpg method in which according to a semi-inverse method, ...

The atlanto-occipital (AO) overlap in combination with atlanto-axial (AA) instability was found in a dog. We hypothesized that ventral fixation of the AA junction can stabilize the atlas and prevent AO overlap by reviewing our past cases with AA instability. A standard ventral fixation of the AA junction using stainless k-wires and polymethyl methacrylate (PMMA) was performed. The dog fully rec...
