background: inflammatory breast cancer (ibc), a subgroup of locally advanced breast cancer (labc), is diagnosed based on clinical findings, and seems to be different from other types of labc. the purpose of this study was to compare clinicopathological characteristics and outcomes between inflammatory and non-inflammatory labc patients at breast cancer research center (bcrc), tehran, iran. meth...

Background: Cancer stem cells (CSCs) are a group of tumor cells with self-renewal property and differentiation potential. CSCs play a crucial role in malignant progression of several types of tumors. However, what is still controversial is the clinicopathological relationship between Nanog marker and its prognostic value in the patients with breast cancer. The expression of Nanog in the patient...

The article is devoted to the problem of incorporation geographic information systems (GIS) in world school practice. authors single out stages GIS application geographical education based on retrospective analysis scientific literature. first stage (late 70s - early 90s 20th century) beginning educational programs and partnership agreements between schools universities. second (mid century 21s...

Stirred tanks and bubble columns are widely used as mixing essels and bioreactors. Average spatial fluid velocity gradients t the level of the eddies or the prevailing shear rate, is an imporant variable in bioreactors but is not easy to characterize. A nowledge of shear rate is essential for at least two main reasons: 1) shear rate influences the average apparent viscosity of nonewtonian fluid...

Rbstract In the AI community, there is an ongoing debate as to the most appropriate theory of inferencing under uncertainty. This paper explores the problem of inference from a different perspective. It is suggested that an inferencing system should reflect an inference policy that is tailored to the domain of problems to which it is applied -and furthermore that an inference polic y need not c...

We present the essential dynmnic model of the •nesospheric photochemical system (PCS) •'md suggest a step-by-step procedure for elaborating such a model of an arbitrary atmospheric PCS. The model demonstrates the same possibilities ofnonlinear dynamic behavior and qualitatively the same dynamic haracteristics a the corresponding original model, but is much simpler than the latter. We show the a...

Employing a buffer gas mixture of CO and CO2, the equilibrium oxygen partial pressure was varied across the Mo/MoO3 proximity line by arying the ratio of concentration of the two gases, as described in an earlier communication. This led to the reduction of MoO in one case and 3 xidation of the reduced phase (Mo or MoO2) in the other with a concomitant variation in the microstructural features o...
