The aim of this case report was to introduce an appliance for correcting severe rotation of anterior teeth in the mixed dentition period. A 9-year-old Iranian boy with a mixed dentition Class I malocclusion complained of a severely rotated of upper right central incisor. There was a mesiodens between the central incisors. The supernumerary tooth was first extracted and then a Whip appliance whi...

1. Apply an understanding of the pathophysiology and risk factors for upper gastrointestinal (GI) bleeding to patient care. 2. Evaluate the most recent guidelines for management and prevention of upper GI bleeding. 3. Devise a plan to effectively manage acute GI bleeding and optimize treatment responses in the individual patient. 4. Design plans for the prevention of upper GI bleeding caused by...

Abstract The aim of this paper is to investigate the behaviour projective images groups which are finite over a term their upper central series. In particular, we prove that for any positive integer k , class finitely generated in -th series has index can be described terms lattice invariants, and so it invariant under projectivities. context, also study have only many maximal subgroups not per...

extended abstract 1. introduction climate change refers to the increase or decrease in the average climatic factors over a long period of time (i.e. more than 30 years). today, climate change has become a human concern and the scientific community are already aware of this fact. global temperature has followed an unprecedented increase over the last hundred years. based on synoptic climatology,...

let $g$ be a finite $p$-soluble group‎, ‎and $p$ a sylow $p$-sub-group of $g$‎. ‎it is proved‎ ‎that if all elements of $p$ of order $p$ (or of order ${}leq 4$ for $p=2$) are‎ ‎contained in the $k$-th term of the upper central series of $p$‎, ‎then the $p$-length of‎ ‎$g$ is at most $2m+1$‎, ‎where $m$ is the greatest integer such that‎ $p^m-p^{m-1}leq k$‎, ‎and the exponent of the image of $p$...
