laparoscopic surgery is now an integral part of the operative repertoire. single-incision laparoscopic surgery (sils) is a new technique developed for performing operations without a visible scar. pneumoperitoneum, as a necessary precondition of laparoscopic procedures, represents the restriction of the surgeon's freedom of movement and can lead to rare but typical complications. the single inc...

hydatid cyst is a zoonotic disease that is common in the mediterranean region. thoracic wall, rib or extrapulmonary intrathoracic localization of the cysts is very rare. giant extrapulmonary intrathoracic hydatid cysts can lead to both diagnostic and treatment difficulties and can be confused with tumor. we present a case of a hydatid cyst with thoracic wall involvement mimicking tumor. we conf...

The notation and terminology used here are introduced in the following papers: [17], [19], [20], [3], [4], [2], [16], [5], [1], [18], [9], [11], [12], [8], [6], [7], [13], [10], [21], [14], and [15]. For simplicity, we use the following convention: X denotes a Banach algebra, p denotes a real number, w, z, z1, z2 denote elements of X, k, l, m, n denote natural numbers, s1, s2, s3, s, s ′ denote...

Let X,Y be locally convex spaces and L(X,Y ) the space of continuous linear operators from X into Y . We consider 2 types of multiplier convergent theorems for a series P Tk in L(X,Y ). First, if λ is a scalar sequence space, we say that the series P Tk is λ multiplier convergent for a locally convex topology τ on L(X,Y ) if the series P tkTk is τ convergent for every t = {tk} ∈ λ. We establish...

The idea of using the compact device with higher heat transfer potential has encouraged researchers to use microchannels. Creating sinusoidal walls is a technique leading better effectiveness and smaller size. In this study, effects discrete sources location on pressure drop are investigated, graphene nanoplatelets/water inside microchannel. For this, installed in smooth microchannel (layout A)...
