appendicitis is the most common surgical emergency with the incidence rate of 6-10%. although several studies have compared the two approaches of open (oa) and laparoscopic appendectomy (la) the technique of choice is still a matter of controversy. considering this background we designed a study to compare oa and la outcomes in our center. one hundred patients were included in this study perfor...

We study a class of tame L-theories T topological fields and their Lδ-extension Tδ⁎ by generic derivation δ. The under consideration include henselian valued characteristic 0 real closed fields. show that the associated expansion has L-open core (i.e., every Lδ-definable open set is L-definable) derive both cell decomposition theorem transfer result elimination imaginaries. Other properties suc...

In this paper, we give a short survey on discrete geometry on red and blue points in the plane, most of whose results were obtained in the past decade. We consider balanced subdivision problems, geometric graph problems, graph embedding problems, Gallai-type problems and others. 1 Notation and Definitions In this paper, we give a short survey on discrete geometry on red and blue points in the p...

INTRODUCTION Nasal cannulas are commonly used to deliver oxygen in acute and chronic care settings; however, there are few data available on delivered fraction of inspired oxygen (F(IO(2))). The purposes of this study were to determine the delivered F(IO(2)) on human subjects using low-flow and high-flow nasal cannulas, and to determine the effects of mouth-closed and mouth-open breathing on F(...

We show that the space Lip0(R) is the dual space of L(R;R)/N where N is the subspace of L(R;R) consisting of vector fields whose divergence vanishes identically. We prove that although the quotient space L(R;R)/N is weakly sequentially complete, the subspace N is not nicely placed in other words, its unit ball is not closed for the topology τm of local convergence in measure. We prove that if Ω...

I. Let C be a closed rectifiable curve or an open rectifiable arc in the 77-dimensional Euclidean space En. Let C, V(C) and L(C) denote respectively the closed convex hull of C, the volume of C and the length of C. Let (c, n), or (0, n), stand for the problem of maximizing V(C), subject to the condition L(C)=const, for a closed curve C, or an open arc C. It is clear that the solution is to be g...

background: splenic cysts are known as rare clinical encounter. classifying into primary (true) and secondary cysts (pseudocysts), true cysts contain cellular epithelial lining and subdivided into parasitic and non-parasitic cysts. this study aimed to determine the outcome of treatment in patients with splenic cyst. methods: all patients with splenic cyst who had been treated in department of g...
