brain tumors are considered in regarded to their size, position and aggressive manner. brain tumors cause several neurologic symptoms. for instance, they increase intracranial pressure due to local damage and displacement of surrounding tissues. in this paper, two glioblastoma multiform cases with more than 15 year- survival have been reported. the first patient was a 52 year- old woman who suf...

Aim: the present study aimed to design and validate decentering schemes for decision making about curriculum based on Schwab’s practical theory and features of the educational system in Iran. Method: in the first step, qualitative methods of "Speculative Essay", "Evaluative Inquiry: Situational Assessment", and "Integrative Inquiry: The Research Synthesis" were employed to explain decentering ...

This paper discusses fundamentals of hybrid system modelling. Emphazis is put on compositionality and the use of multiform time. Compositionality refers to the ability of freely composing hybrid systems. Since hybrid systems are considered, different time indices occur, and modularity calls for considering “time” as local to each module, this is what is called multiform time. The proposed frame...

Two patients known to have coronary artery disease died suddenly outdoors while active. Neither had symptoms or signs of acute myocardial infarction. They were being monitored by continuous tape recording of the electrocardiogram at the time of death. In one patient the cause of death was cardiac arrest, preceded by bigeminy and multiform ventricular ectopic beats, in the other ventricular fibr...

We present an introduction to the mathematical theory of the Lagrangian formalism for multiform fields on Minkowski spacetime based on the multiform and extensor calculus. Our formulation gives a unified mathematical description for the main relativistic field theories including the gravitational field (which however will be discussed in a separate paper). We worked out several examples (includ...

background & aim: glioblastoma multiforme (gbm), the highest grade glioma (grade iv), is the most malignant form of astrocytoma in adults. this study aimed at evaluating the relationship between demographic, clinical and medical factors with gbm outcome. methods & materials/patients: through a cross-sectional design, 58 patients with newly diagnosed gbm were studied from 1999 to 2015 in guilan ...
