Let k be an arbitrary commutative ring. We associate fonctorially to any simplicial set X a differential graded algebra Ŵ∗(X) with a globally defined braiding, which is an improvement of a previous work [3,4]. If k= Z and with some mild finiteness conditions on X, we show that the quasi-isomorphisms class of Ŵ∗(X) as a braided differential graded algebra determines the p-adic homotopy type of X...

Nous revenons dans cet article sur une conjecture que nous avons été conduits à présenter dans un précédent travail ( [2], voir aussi [3] ) . Il s’agit d’une identité remarquable, qui se formule de manière extrêmement élémentaire dans le cadre de la théorie classique des partitions. Nous la démontrons ici sous sa forme la plus générale, et nous explicitons plusieurs de ses conséquences. Notre d...

radiation-related wounds challenge surgeons in all disciplines of surgery. wound-healing complications are commonplace, and solutions for reconstruction are limited. muscle and musculocutaneous flaps have improved this situation. but the question is, does previous radiation of the muscle to be transposed affect the outcome? 143 consecutive previously irradiated patients treated with muscle or m...

cutaneous leiomyosarcoma is a relatively rare tumor accounts for about 2-3% of superficial soft tissue sarcomas. it occurs more frequently in males in fifth and sixth decades with a predilection for extremities. we report a 27 years old male with cutaneous leiomyosarcoma of thigh, previously diagnosed as pleomorphicfibroma. the tumor composed of pleomorphic spindle shaped cells with blunt ended...

background: the increase in the prevalence of cesarean section (c-section) in recent decades has become a public health problem worldwide. studies of cesarean section in order to identify the causes and form policies and interventions to reduce the incidence of this health problem are necessary. this study was conducted with the aim to investigate the causes of c-sections performed at niknafs a...
