In this paper we unify several existing regularity conditions for graphs, including strong regularity, k-isoregularity, and the t-vertex condition. We develop an algebraic composition/decomposition theory of conditions. Using our theoretical results show that a family non rank 3 graphs known to satisfy 7-vertex condition fulfills even stronger condition, (3,7)-regularity (the notion is defined ...

this paper examines edward said’s views on music and its connection with key concepts such as orientalism and worldliness in his writings. it is suggested that to see the importance of classical western music as a key component of western culture in said’s work, one has to take into account the centrality of culture in his critical views and the stress he puts on its complicity with western imp...

Extramedullary hematopoiesis (EMH) is a physiological compensatory phenomenon occurring in many hemolytic anemias including thalassemia. Besides transfusion, radiotherapy, surgery or a combination of these modalities, hydroxyurea (HU) as an optimal treatment has been described occasionally. We described a case of beta-thalassemia major who has been on regular blood transfusion and developed EMH...
