Introduction Retained primitive reflexes can disturb natural development and involve difficulties in social and educational children's life. They can also impact on psychomotor development. Mature responses in a child's psychomotor progress can only occur if the central nervous system itself has reached maturity. The process consist the transition made from brain stem reflex response to cortica...

conclusions pnet/ews should be included in the differential diagnosis of renal tumors in symptomatic young adults. patients with localised pnet/ews treated with a combination of surgery and chemotherapy have an excellent chance of long-term survival, as in the case we have presented. introduction primitive neuroectodermal tumor (pnet)/ewing’s sarcoma (ews) belongs to a family of neoplasms that ...

toos fertile plain, located between two mountain ranges hezarmasjed and binalood, has attracted different ethnic groups through ages due to environmental conditions, and has provided a proper ground for human inhabitation and continuation of life since oldest times. discovery of handmade tools dated to lower paleolithic age in the middle of the plain and banks of kashaf river (kashaf rud), exis...

We initiate the study of reducts of relational structures up to primitive positive interdefinability: After providing the tools for such a study, we apply these tools in order to obtain a classification of the reducts of the logic of equality. It turns out that there exists a continuum of such reducts. Equivalently, expressed in the language of universal algebra, we classify those locally close...

‎given a finite non-cyclic group $g$‎, ‎call $sigma(g)$ the smallest number of proper subgroups of $g$ needed to cover $g$‎. ‎lucchini and detomi conjectured that if a nonabelian group $g$ is such that $sigma(g) < sigma(g/n)$ for every non-trivial normal subgroup $n$ of $g$ then $g$ is textit{monolithic}‎, ‎meaning that it admits a unique minimal normal subgroup‎. ‎in this paper we show how thi...

We propose an approach towards multi-agent system for simulation and detection of primitive collective behaviors emerging from a crowd in panic. This paper presents various works on which our method is based, by methods of planning and decisions allowing emergence of primitive collective behaviors. We present then an implementation in a virtual environment and detection experiments of emergent ...

This case comprises several primitive tasks that can be solved straight away with most transformation tools. The aim is to cover the most important kinds of primitive operations on models, i.e. create, read, update and delete (CRUD). To this end, tasks such as a constant transformation, a model-to-text transformation, a very basic migration transformation or diverse simple queries or in-place o...

Wireless ad hoc and sensor networks are constantly gaining importance due to their wide range of possible applications. The employed sensor hardware and software is becoming more complex and projects realized by means of sensor networks are increasingly ambitious. Despite these rapid advantages tools for sensor network development are still very primitive: A generic text editor and a command li...

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...
