We experimentally investigate the energy dissipation rate in sinusoidally driven boxes which are partly filled by granular material under conditions of weightlessness. We identify two different modes of granular dynamics, depending on the amplitude of driving, A. For intense forcing, A>A(0), the material is found in the collect-and-collide regime where the center of mass of the granulate moves ...

Metastases to the breast are uncommon, accounting for 0.5% of breast tumors, and most of them are originated from lymphoma, melanoma and carcinomas of various organs. Alveolar soft part sarcoma (ASPS) is a very rare neoplasm that is usually found in the lower extremities. Lungs are the common site of dissemination and may represent initial manifestation of disease. We report a clinically unsusp...

The granular cell tumor of the breast is a rare and usually benign disease that appears clinically radiologically like malign tumor. We report case GCT in woman 41 years, who present suspect later. anatomopathological examination showed proliferation large tumorectomy was realized. immunostaining with PS100 NSE protein confirm nature

Granular cell tumor presenting as a thyroid mass is very rare. It may arise from the thyroid gland or from the tissues/organs adjacent to the thyroid gland. It may cytologically mimick other common thyroid tumors. The accurate evaluation of these tumors may be important for management. We describe a granular cell tumor arising from the tissue adjacent to the thyroid gland and with multiple orga...

PURPOSE To report a case of granular cell tumor as a rare orbital pathology. CASE REPORT A 50-year-old female presented with a 4-year history of diplopia, right ocular displacement and a firm nontender mass in her right lower lid. Computed tomography (CT) scan of the orbit disclosed a well-defined mass in the right inferior orbit involving the right inferior rectus. Subtotal excision of the m...

The validation of a DVI approach for the dynamics of granular material project focuses on comparing the experimental and simulation results of granular flow for two tests in the Chrono::Engine simulation environment. An aluminum rig was designed and fabricated to measure the mass flow rate of a given amount of granular material flowing due to gravity through a slit. The mass flow rate was initi...

PURPOSE The aim of our study was to characterize and describe the different immunohistochemical expression patterns of cytokeratin 8/18 (CK8/18) in breast tumors and to make a correlation between histopathology, immunohistochemistry for CK8/18 and its possible diagnostic value of this pair of keratins for molecular classification of breast cancers. MATERIAL AND METHODS Forty cases of breast t...
