We propose multilayer cylindrical invisibility cloaks that are optimized for oblique incidences through a combination of analytic formalism of scattering and genetic optimization. We show that by using only four layers of homogeneous and anisotropic metamaterials without large values of constitutive parameters, the scattering for oblique incidences can be reduced by 2 orders. Although the optim...
In the present Study, a dissimilar joint of carbon steel sheet EN 10025 with 316 L has been welded by FSW and the welding parameters were optimized by RSM software method. For investigation of mechanical properties and microstructural analysis carried out by using optical, scanning electron microscopes with EDS analysis, tensile and hardness test of different area of joints, SZ, TMAZ, HAZ, thei...
The main concerns of network operators is the improvement of system parameters, and various ways have been developed to achieve this goal. If the use of renewable energy including wind in the grid is used, the sustainability debate and the status of the power system parameters will be twofold. In the upcoming research, we will examine the status of the parameters by placing the Facts on the 24-...
Background and aims: Increasing production and the use of pesticides for agricultural purposes can lead to many environmental and human health risks. Therefore, assessment of their concentration in occupational and environmental samples is necessary to estimate exposure levels. This study was aimed to use a synthesized molecular imprinted polymer (MIP) as a novel and specific absorbent for resi...
The aim of this study is to prepare propolis flavonoids liposome (PFL) and optimize the preparation condition and to investigate further whether liposome could promote the immunoenhancement activity of propolis flavonoids (PF). PFL was prepared with ethanol injection method, and the preparation conditions of PFL were optimized with response surface methodology (RSM). Moreover, the immunoenhance...
