Hemangioma, which is a rife benign proliferative lesion with vascular tissue origin, is the most common vascular anomaly of infancy. Cellular hemangioma is one type of these tumors, known as the vascular channel formation of endothelial cells. This report describes a 34-year old man with an exophytic lesion on the lower lip , firm, dome shape ,smooth surface with mild keratosis who came to us  ...

Various mechanisms have been proposed for the dynamic cause and kinematic development of gneiss domes. They include (1) diapiric fl ow induced by density inversion, (2) buckling under horizontal constriction (i.e., extension perpendicular to compression), (3) coeval orthogonal contraction or superposition of multiple phases of folding in different orientations, (4) instability induced by vertic...

The Huangling dome, which is one of the largest tectonic domes in South China continent, was formed between Late Jurassic and Early Cretaceous, when regional compression eventually replaced by extension. This raises an issue about whether dome generated compression, extension or both. study integrates single-grain zircon (U–Th)/He (ZHe) dating with thermal modeling to better constrain formation...

The wind loads considerably influence lightweight spatial structures. An example of spatial structures is scallop domes that contain various configurations and forms and the wind impact on a scallop dome is more complex due to its additional curvature. In our work, the wind pressure coefficient (Cp ) on the scallop dome surface is studied numerically and experimentally. Firstly, the programming...

A cell line has been established from an alveologenic lung adenocarcinoma that develops in newborn NFS/N mice after i.p. inoculation with a carcinoma-inducing retrovirus. A clonal derivative of this cell line, 3041, forms adenocarcinomas when injected into syngeneic weanling mice and in culture retains several properties typical of alveologenic type 1 cells. These include morphological details,...
