abstract background: the varieties of treatment methods for the scaphoid non:::::union::::: have always been a discussable issue for orthopaedic surgeons. the current study, considered to be review for treatment results of the patients who sustained the scaphoid non:::::union::::: with or without avascular necrosis and compared these two groups clinically and radiologically. methods: the clinic...

conclusions our results in terms of asami scores are comparable with the published literature. furthermore, our return to work is better than most european studies (63%). all our patients said they would have the procedure again. we attribute this success partly to the multidisciplinary approach. we recommend early referral to a dedicated unit if there is any evidence of a non-:union:. results ...

isolation of pigmented t.violaceum from a patient with endothrix infection associated with the inflammatory and kerion symptoms and also isolation of the non- pigmented strain from another patient with non-inflammatory symptoms, led us to investigate the enzymic activities in both strains. most of the studies on dermatophyte compoxition have shown the relationship between proteolytic enzymes an...

data envelopment analysis (dea) measures the relative efficiency of a homogenous set of decision-making units (dmus) when multiple inputs and outputs are present. the deabased malmquist productivity index measuring the productivity change of dmus over time has proven itself to be a valid tool to compare group performance. however, in the previous models developed for this purpose, it was suppos...

let c be a field of subsets of a set i. also, let     1 i i be a non-decreasing positivesequence of real numbers such that 1, 1 0 1   i  and    11 i i . in this paper we prove thatbv of all the games of -bounded variation on c is a non-separable and norm dual banach space of thespace of simple games on c . we use this fact to establish the existence of a linear mapping t from...

the non commuting graph of a non-abelian finite group $g$ is defined as follows: its vertex set is $g-z(g)$ and two distinct vertices $x$ and $y$ are joined by an edge if and only if the commutator of $x$ and $y$ is not the identity. in this paper we prove some new results about this graph. in particular we will give a new proof of theorem 3.24 of [2]. we also prove that if $g_1$, $g_2$, ..., $...

introduction: impaction of third molars can be associated with a number of sequelae, each requiring a different type of treatment. the purpose of this study was to assess the changes in the position of lower third molars following extraction and non-extraction orthodontic treatments. methods: pre- and post-treatment panoramic radiographs of 26 class i malocclusion patients (4 male and 22 female...

let $l$ be a lattice in $zz^n$ of dimension $m$. we prove that there exist integer constants $d$ and $m$ which are basis-independent such that the total degree of any graver element of $l$ is not greater than $m(n-m+1)md$. the case $m=1$ occurs precisely when $l$ is saturated, and in this case the bound is a reformulation of a well-known bound given by several authors. as a corollary, we show t...
