Achievement of an activity generally depends on the achievement of sub-activities. These sub-activities are related with each other in terms of ordering among them and data they access. We can consider a business process as an activity to be achieved and we can deene its sub-activities. The correct and eecient execution of a business process necessitates capturing and deening the relations amon...

Introduction: Protecting the vital organs in radiation therapy is one of the most important issues. Cerrobend alloy, the most common material used as the shield, is melted several times and used for different patients. In this study changes in attenuation coefficient of cerrobend due to melting was investigated.   Materials and Methods: In melting furnace, ...

We study the blocks of interpoint distances, their distributions, correlations, independence and the homogeneity of their total variances. We discuss the exact and asymptotic distribution of the interpoint distances and their average under three models and provide connections between the correlation of interpoint distances with their vector correlation and test of sphericity. We discuss testing...

In spite of broad improvements in construction technology, cement is still stayed as binding material for construction purposes. Cement industries are the main sources for the contribution of carbon dioxide (co2) into the atmosphere. So, there is a need to use new materials as binders (green binders) in substitute for cement, which leads to reducing the production of cement. In this study, fly ...

Fine needle aspiration (FNA) is a rapid tool for detection of breast carcinomas. Evaluation of estrogen and progesterone receptors (ER, PR) and HER2 expression by immunohistochemistry (IHC) are routinely performed in breast carcinomas. Formalin fixation of tissue for a minimum of 6 hours, and for HER2 not more than 48 hours is the current recommended practice. In this retrospective study, we co...

Martin J. Sharry and Anne Penfold Street, Centre for Combinatorics, Department of Mathematics, The University of Queensland, Brisbane 4072, Australia. As a first step towards finding all 4-(12, 6, 4) designs which are not 5-(12, 6, 1) designs, it is shown that if such a design has a pair of blocks with five points in common, then there is a unique way of assigning the replicas of the seven poin...
