In this paper we investigate the interaction between a granular layer and an elastic foundation using a coupled Discrete Element Method-Finite Element Method (DEM–FEM) computational model. We use this dynamics code to simulate quasi-static bending of the granular layer and we observe the changes taking place in the structure of the force chains for two cases: with and without rolling resistance...

Granulomatous lobular mastitis (GLM) is a rare and benign condition of unknown etiology, which has been described recently. It primary affects young parous women and usually presents with a unilateral and extra-areolar breast mass. The condition may clinically mimic breast cancer, sometimes leading to misdiagnosis resulting in unnecessary breast surgery.We report two ca...

A system was developed to measure the mass flow of granular fertilizer material in aerial spreader ducts. The flow process was regarded as the sequential passage of clusters containing multiple particles with varying diameters. An optical sensor was used to measure the cluster lengths on the fly. In a low–density flow regime, the diameter of each particle could be measured individually (this is...

A primary fibrosarcoma of the breast is a rare tumor. Here we report on a case of a primary fibrosarcoma of the breast that presented as a palpable left breast mass in a 47-year-old woman. The physical examination revealed a 3 cm sized, round mass in the left upper outer breast. The mammograms revealed a 3 cm sized, partially circumscribed and partially obscured, high density mass in the upper ...

A 34-year-old man found a mildly tender preauricular mass. Ultrasonography revealed an anechoic mass in the superficial lobe of the parotid gland. Magnetic resonance imaging showed thin ring-like contrast enhancement and homogenously high intensity on T2-weighted images. The mass was resected due to its rapid growth. The cystic lesion contained keratine-like material and a stratified squamous e...

Breast cancer is one of the leading causes of death among women. Mammography remains today the best technology to detect breast cancer, early and efficiently, to distinguish between benign and malignant diseases. Several techniques in image processing and analysis have been developed to address this problem. In this paper, we propose a new solution to the problem of computer aided detection and...

In order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. The test rig has longitudinal trapezoidal slots in its conveying pipes. Through experimentation, a correlation for friction factor in terms of solid mass flow rate, fluid flow rate and Froude number is presented. It is shown that the mixture friction factor for pipes with inn...

background: potential association of leptin (lep) gene polymorphisms has been suggested in the processes leading to breast cancer initiation and progression. we investigated whether genetic variations in the lep -2548g/a gene are associated with risk of breast cancer. methods: this case-control study consisted of 100 breast cancer cases and 100 control subjects without breast cancer that matche...
