To weaken the harm of Al–Si coating and increase strength welded joints, variable thicknesses Ni foil (Ni, an austenitic formation element) were added to lap laser welding Al–Si-coated 22MnB5 hot stamping steel/galvanized steel joints. The joints’ weld appearance, microstructure, mechanical properties explored. altered from X shape a Y with increased thickness foil. During welding, was melted d...

Abstract Particulate fouling on structured surfaces is typically quantified using the integral thermal or mass-based resistance. The observed geometries may be structures that can improve heat transfer in exchangers (e.g., dimples), cavities components, more complex geometries. However, due to limited accessibility requirement for a locally resolved measurement, existing quantification methods ...

A rare case of non-puerperal chronic uterine inversion secondary to sub mucous fibroid in a 38-year-old woman is presented. There was complete uterine inversion with the incarcerated inverted uterus protruding through the vvgina beyond the vulva. The sub mucous fibroid was attached to the fundus. At laparotomy, a dimple with a constriction ring was found in the position of the uterus. The dista...

We investigate the structure and phase behavior of a two-component (binary) polymer brush in a solvent within self-consistent field theory as a function of the chains' stretching, the composition, and the incompatibility. Grafting the chains irreversibly prevents macrophase separation and the chains assemble into three-dimensional structures with lateral periodicity. At small incompatibilities ...

Pyloric atresia is a congenital anomaly manifested by gastric outlet obstruction. The radiographic signs are characterised by the presence of the gas-bubble sign, the pyloric dimple sign and the absence of the beak sign. The differential diagnosis of these signs is discussed in view of other gastric outlet obstructions. Ultrasonography is of value in demonstrating the absence of the normal echo...

A female neonate who was born as large for gestational age baby to a Diabetic mother had a continuous murmur in the left infraclavicular area with scolisis toward right and deficient ribs in the right side of her chest wall. She had a sacral dimple and a skin tag in the right lower back. Radiograph revealed hemivertebrae from T1-T6 level with absent third and seventh ribs and fused fourth, fift...
