One of the troublesome aspects of numerical modeling is to determine open boundaries for a model and to make sure that the boundary conditions employed at the open boundaries are compatible with physical processes being simulated within the interior of the model domain. In this investigation the accuracy of the water level data derived from delft3D employing nesting procedure were studied. Thes...

OBJECTIVE To investigate and compare the effects on pain of intraurethral 2% lidocaine gel and plain lubricating gel in male patients underwent flexible cystoscopy. MATERIAL AND METHODS The data of 220 male patients who underwent flexible cystoscopy between March 2012 and August 2014 were retrospectively analized. The patients were divided into 2 groups according to using intraurethral gel ty...

A Uniform Lying Helix (ULH) liquid crystal device (LCD) fabricated by utilizing the characteristics of shear flow alignment as well as dielectric anisotropy was demonstrated. Cholesteric liquid crystals with a short helical pitch can exhibit an electric field-induced tilt. These experimental results indicate that it is possible to realize a high-speed response flexible LCD using plastic substra...

introduction as a dynamic phenomenon, boundary is one of the basic issues in political geography and geopolitics. it is not a geographical and fixed phenomenon; rather, it has its own internal dynamic features, creates new realities, and affects the lives of people and groups living in its vicinity. different types of boundaries, such as political, social, economic, and virtual can be impenetra...
