Collapsed membranes and daughter cysts are pathognomonic for hydatid cysts on imaging. The comma-shaped lesions, visible within the hydatid cyst in sagittal view of MRI, are collapsed membranes. Although primary hydatid cyst of pelvic cavity is rare, clinicians should remember to include hydatid cysts in differential diagnosis of pelvic cysts.

Arch shaped microelectromechanical systems (MEMS) have been used as mechanical memories, micro-relays, micro-valves, optical switches, and digital micro-mirrors. A bi-stable structure is characterized by a multivalued load deflection curve. Here, the symmetry breaking, the snap-through instability, and the pullin instability of a sinusoidal shaped MEMS under static and dynamic electric loads ha...

In this paper, a new compact wideband monopole antenna is presented for wireless communication applications. This antenna comprises of a new radiating patch, a new arc-shaped strip, microstrip feed line, and a notched ground plane. The proposed radiating patch is combined with a rectangular and semi-circular patch and is integrated with a partial ground plane to provide a wide impedance bandwid...

The C-ethyl-2-methylresorcinarene (1) forms 1:1 in-cavity complexes with aromatic N,N'-dioxides, only if each of the aromatic rings has an N-O group. The structurally different C-shaped 2,2'-bipyridine N,N'-dioxide (2,2'-BiPyNO) and the linear rod-shaped 4,4'-bipyridine N,N'-dioxide (4,4'-BiPyNO) both form 1:1 in-cavity complexes with the host resorcinarene in C4v crown and C2v conformations, r...

In this paper, we investigate the light trajectories and shadow properties in rotating version of null naked singularity (NNS) spacetime which is derived using Newman- Janis algorithm without complexification method. We discuss some geometrical causal structure Rotating Naked Singularity (RNS) spacetime. The gravitational lensing a analyzed, results are compared to those Kerr black hole. case h...

Modeling of the separation catalyst particles from gas using two devices, a cyclone and novel separator with arc-shaped elements, was performed for fluidized-bed dehydrogenation C4–C5 paraffins to isoolefins as an example. The proposed dust collector allows one reduce erosive wear by several times (~6.5-fold) in identical regimes at parameters process. effect particle size on analyzed under nea...

BACKGROUND To compare dosimetric parameters of volumetric modulated arc therapy (VMAT) and non-coplanar intensity modulated radiotherapy (IMRT) for nasal cavity and paranasal sinus cancer with regard to the coverage of planning target volume (PTV) and the sparing of organs at risk (OAR). METHODS Ten patients with nasal cavity or paranasal sinus cancer were re-planned by VMAT (two-arc) plan an...

The work gave a detailed systematic morphology by optic and scan electron microscopy of two parasites; Raillietina echinobothriida Megnin, 1880 and Spirora meleagaris n. sp. infecting domesticated turkey, with some important description characters. SEM revealed that tegument of R. echinobothriida exhibits, filamentous, microtriches and sensory papillae densely covered the tegument of entire bod...

This communication describes a facile method for the synthesis of conical-shaped Au nanoparticles with a hollow cavity by combining interfacial reaction and ultrasonic cavitation. The Au nanocones showed an enhancement factor of 7.7 × 10(8) in surface enhanced Raman scattering (SERS) detection.
