Primitive and Totally Primitive Fricke Families with Applications

the incorrect applications of primitive and common predications

the distinction between primitive predication and common predication is applied to solve some problems in islamic philosophy, some of which are incorrect in our point of view. some of the problems contain paradoxes and some others include independent philosophical discussions: 1. stating about absolute non-existents, 2. problems of subjective existence, 3. liar paradox and russell’s paradox, 4....

Primitive Ideal Space of Ultragraph $C^*$-algebras

In this paper, we describe the primitive ideal space of the $C^*$-algebra $C^*(mathcal G)$  associated to the ultragraph $mathcal{G}$. We investigate the structure of the closed ideals of the quotient ultragraph $  C^* $-algebra  $C^*left(mathcal G/(H,S)right)$ which contain no nonzero set projections and then we characterize all non gauge-invariant primitive ideals. Our results generalize the ...

Primitive Neuroectodermal Tumor of the Kidney

Primitive neuroectodermal tumor (PENETs) is an uncommon malignancy of bone and soft tissue witch rarely occurs in the kidney. In more than 90% of the cases, the tumor cells relieves a balanced translocation (11; 22) (q24; q12). Immunohistochemical staining may be required for diagnosis of PENET. The cells of tumor express CD99, vimentin, NSE, FL1 but do not express Ck, LCA, myogenin, and WT1. W...

Peripheral Primitive Neuroectodermal Tumor of the Pelvis

The primitive neuroectodermal tumor (PNET) belongs to a group of highly malignant tumors and is composed of small round cells of a neuroectodermal origin. Categorized in the same tumor family as Ewing sarcoma, the PNET is most likely to occur in bones and soft tissues. However, a small number of PNET cases arising in the pelvis have been reported as well. We present three cases of pelvic PNET: ...
