Atlantoaxial dislocation in children is a very rare condition. We present the case of a dislocation happened during a break-dance maneuver. The purpose of this report is describing dangers of break-dancing and discussing the treatment we chose. The patient was followed up until 12 months after surgery. Magnetic resonance imaging and computed tomography of the cervical spine were evaluated. Tran...

in this paper we obtain coefficient characterization‎, ‎extreme points and‎ ‎distortion bounds for the classes of harmonic $p-$valent functions‎ ‎defined by certain modified operator‎. ‎some of our results improve‎ ‎and generalize previously known results‎.

the main aim of this paper is to introduce three classes $h^0_{p,q}$, $h^1_{p,q}$ and $th^*_p$ of $p$-harmonic mappings and discuss the properties of mappings in these classes. first, we discuss the starlikeness and convexity of mappings in $h^0_{p,q}$ and $h^1_{p,q}$. then establish the covering theorem for mappings in $h^1_{p,q}$. finally, we determine the extreme points of the class $th^*_{p}$.

We discuss a phenomenon that appears when ‘even’ occurs in questions. Specifically, an inference of what we call ‘‘extreme ignorance’’ is projected onto the speaker. We argue that this effect arises when the known unlikelihood ‘even’ focuses an entire question, resulting in the focused question being the least likely to be asked. Specific implicatures then conspire to bring about the inference ...

Counting the number of elements in finite sets Si (where i typically ranges over some index set I such as the non–negative integers or a cartesian product of the non–negative integers) is surely one of the oldest and most fundamental problems in mathematics. It is in the nature of the subject that only a few enumeration problems have a compact solution in terms of a simple explicit formula in i...

Leaching of a low-grade lead and zinc oxide ore was studied by an organic reagent, citric acid. The quadratic mathematical models were developed for the relationship among the influential parameters and lead and zinc recoveries. Leaching rate was strongly affected by the interactive effects of factors. It was also found that the quadratic effects of stirring speed and linear<e...

Coronavirus Disease 2019 (COVID-19) is a significant medical and public health problem in the world. It is believed that it can worsen in extreme conditions. Also, it is suggested that blood disorders such as sickle cell disease (SCD) may increase the risk of COVID-19 symptoms. The present study reports a family facing COVID-19, in which one of two members with SCD presented with fever, repeate...

Extreme value theory is a practical and useful tool for modeling and quantifying risk. In this article, after introducing basic concepts, we indicate how to apply it within a financial framework.

This paper develops the use of ‘guided interviews’ and questionnaires in an empirical study of a small software development company. In particular, the study identified a number of human issues in communications, technology, teamwork and political factors that significantly influenced the implementation and evolution of eXtreme programming into a software development team.
