this study aimed to investigate the effects of tow nanoparticles (nps) on the absorption,accumulation, reproduction of the eisenia fetida. a 4×2×2 factorial experiment in a randomized completeblock design with three replications was conducted. the factors included in the experiment are the content ofnps at four levels (0, 0.4, 0.8, and 1.2gr/kg weight of substrate), the type of nps at two level...

Abstract In order to evaluate the response of rice plant (Anber 33 cultivar) fertilization with silica, bio-organic fertilizers and spraying nano-titanium nano-cobalt on some growth indicators yield crop Anber cultivar, The field study was conducted in Al-Tali’a district (boycott 41 - Al-Hussainiya) Babylon province, Iraq. for period from 15/6/2021 23/11/2021.The experiment according a randomiz...

Fe₃O₄/wood fiber composites are prepared with a green mechanical method using only distilled water as a solvent without any chemical agents, and then a binderless composite board with high mechanical properties is obtained via a hot-press for electromagnetic (EM) absorption. The fibers are connected by hydrogen bonds after being mechanically pretreated, and Fe₃O₄ nanoparticles (NPs) are attache...

In this research, static stresses analysis of boron nitride nano - tube reinforced composite (BNNTRC) cylinder made of poly - vinylidene fluoride (PVDF) subjected to non - axisymmetric thermo - mechanical loads and applied voltage is developed. The surrounded elastic medium is modelled by Pasternak foundation. Composite structure is modeled based on piezoelectric fiber reinforced composite (PFR...

Mis (1975; 1977) proposed that a midbrain circuit involving the accessory oculomotor nuclei (nucleus of Darkschewitsch, interstitial nucleus of Cajal) is necessary for inhibition of the conditioned nictitating membrane response (NMR) of the rabbit. The present study attempted to determine: a) whether neurons of the accessory oculomotor nuclei, and not fibers of passage, are necessary for condit...

Motivated by the possibility of engineering nanostructured surfaces for efficient nano-thermophotovoltaic power generation, we investigate whether and how Stein's phenomenon may effectively be incorporated into nanoparticle characterization based on scattering data. The statistical innovation in our approach is to employ a form of nonlinear shrinkage in the compound estimation of scattering pro...

In this paper, we report our experimental study on directly coupling a micro/nano fiber (MNOF) ring with a side-polished fiber(SPF). As a result of the study, the behavior of an add-drop filter was observed. The demonstrated add-drop filter explored the wavelength dependence of light coupling between a MNOF ring and a SPF. The characteristics of the filter and its performance dependence on the ...
