OBJECTIVES This study analyzes and compares exposures to prescription opioids among children and adolescents younger than 20 years old in the United States. METHODS Data from the National Poison Data System for 2000 through 2015 were analyzed. RESULTS Poison control centers received reports of 188 468 prescription opioid exposures among children aged <20 years old from 2000 through 2015. Th...

We will determine whether a given surgery on a 2-bridge knot is reducible, toroidal, Seifert bered, or hyperbolic. In [Th1] Thurston showed that if K is a hyperbolic knot, then all but nitely many surgeries on K are hyperbolic. In particular, for the Figure 8 knot, it was shown that exactly 9 nontrivial surgeries are non-hyperbolic. Let Kp=q be a 2-bridge knot associated to the rational number ...

cases with hirschsprung’s disease show the functional intestinal obstruction. obstruction in these patients may lead to bacterial overgrowth with stasis and inflammation of the colon. bacterial overgrowth can cause hyperammonemia that makes lethargy and loss of conscious and finally admitting in icu. the purpose of this case report is to present a case that had hirschsprung’s disease and referr...

Polar parameterizations of star-shaped domains are based on the line segments that connect a suitably chosen center point with points domain's boundary. Valid (i.e., regular everywhere except at point) polar obtained when choosing from kernel domain. Recently, flexibility these has been enhanced by considering so-called arc fibrations (Jüttler et al., 2019), which use circular arcs in order to ...
