Complete Penoscrotal Transposition: A Case Report

Abstract

Penoskrostal transpozisyon, dış erkek genitalinin oldukça nadir görülen konjenital bir anomalisi olup penisin skrotuma göre malpozisyonu ile karakterize edilir. Komplet ve inkomplet olmak üzere iki tür penoskrotal transpozisyon varyantı vardır. Bu olgu sunumunda, 11 yaşında, komplet penoskrostal transpozisyonu olan bir erkek çocuk radyolojik ve fizik muayene bulguları ile birlikte tarif edilmiştir.

Intumescent fire‐retardant coatings for plastics based on poly(vinylphosphonic acid): Improving water resistance with comonomers

“…To avoid the use of resin, fire‐retardant monomers can be directly polymerized on the surface of the substrate, with phosphorus‐containing monomers attracting interest owing to the ability of phosphorus to promote char formation during combustion with the char thus formed providing a thermal barrier over the underlying substrate . For example, vinyl phosphonic acid (VPA), several dialkyl vinyl phosphonates, and various vinyl and allyl phosphine oxides have been used in this way in copolymers, or as oligomers that react with a polymeric binder to form a branched or grafted phosphorylated polymer . Furthermore, some phosphorus‐containing monomers can be directly grafted or polymerized on textile substrates to give a phosphorylated polymer film; for instance, VPA has been polymerized on finished textiles such as cotton, polyamide, polyacrylonitrile and polyester, via photo‐induced polymerization .…”
