Background and objectives: Echinophora cinerea belongs to Apiaceae family and its aerial parts are used as vegetables and for seasoning yoghurt and cheese, and for treatment of digestive disorders in Chahar Mahal and Bakhtiari province, Iran. Despite its traditional use about dietary and pharmacological studies (approximately 13 in vivo, in vitro and ...

Due to one-dimentional nanostructures’ unique properties and their intriguing applications, there has being a great demanding on the technologies which are able to produce such structures. Among the applicable strategies, electrospinning seems to be the simplest approach to generate continues nanofibers with ultrathin and uniform diameters (Li & Xia, 2004). Electrospinning is a spin technology ...

We give an indication that gravity coupled to an infinite number of fields might be a renormalizable theory. A toy model with an infinite number of interacting fermions in four-dimentional space-time is analyzed. The model is finite at any order in perturbation theory. However, perturbation theory is valid only for external momenta smaller than λ− 1 2 , where λ is the coupling constant.

Abstract:In this paper, under some assumptions a nonlinear controller based on differential geometry theory of nonlinear control system and pole-assignment method is designed, and applied to synchronize output signals of high dimensional chaotic system. Using the method, we can synchronize output signals formed by linear or nonlinear composition of single or multiple state variables of the chao...

Comprehensive treatment planning is of paramount importance in leveling and aligning the impacted maxillary canines. In such cases, retrieval of all pertinent clinical information leading to proper diagnosis and prediction of treatment complexity weighs utmost importance. There are many factors including modalities of treatment, governing management of impacted canines. The aim of our study was...

Method Twenty-six patients with DLKS underwent gait analysis using 3-dimentional motion analysis system (3D-MAS). Two reflection markers were attached to the skin surface on C7 and S1 spinous processes in all patients. Then they walked on treadmill at self-selected walking speed, and 3-dementional location of these surface makers (C7.S1) were recorded by synchronized 4 cameras that were placed ...

September 1999 23 medicamundi The first crude 3-D reconstructions of ultrasound data were performed nearly fifteen years ago. There was rapid development in reconstruction algorithms for surface and volume rendering, but clinical application of 3-D ultrasound was handicapped by problems intrinsic to ultrasound imaging, such as speckle, clutter, grating lobe and other artifacts. It has taken a n...

In the present study, an attempt has been made to synthesize 3-methyl-4-arylmethylene isoxazole-5(4H)-one derivatives through sonication of hydroxylamine hydrochloride, ethyl acetoacetate and benzaldehyde derivatives in the presence of imidazole as a novel and effective catalyst in aqueous media. This green reaction under ultrasound irradiation has advantageous compared to conventional...
