Acylated xylan-based magnetic Fe₃O₄ nanocomposite hydrogels (ACX-MNP-gels) were prepared by fabricating Fe₃O₄ nanoctahedra in situ within a hydrogel matrix which was synthesized by the copolymerization of acylated xylan (ACX) with acrylamide and N-isopropylacrylamide under ultraviolet irradiation. The size of the Fe₃O₄ fabricated within the hydrogel matrix could be adjusted through controlling ...

purpose this study was performed to introduce and evaluate the potential of kinematic magnetic resonance imaging (kmri) using a high-field open-magnet magnetic resonance (mr) system. methods we attempted to perform kmri of healthy volunteers’ lumbar spine and knee in the lateral position and ankle in the supine position utilizing the superconducting, horizontally opened, 1.2 t mr system (oasis,...

A novel bioconjugate of stearic acid capped maghemite nanoparticle (gamma-Fe(2)O(3)) with bovine serum albumin (BSA) was developed by taking recourse to the fatty acid binding property of the protein. From FT-IR study, it was found that conjugation took place covalently between the amine group of protein molecule and carboxyl group of stearic acid capped maghemite nanoparticle. TEM study furthe...

Custody transfer is an important activity in the oil and gas industry which requires high accuracy. In keeping metering system accurate condition, dynamic testing needed as evaluation of custody system. carrying out testing, software so that calculations will be more minimize errors. Calculation market currently quite expensive does not cover all calculation needs field, it necessary to make su...

This paper gives an overview of nowadays used simulation models and measurement methods in order to determine iron losses in electrical machinery. The paper provides machine designers and system engineers with an overview of suitable iron loss models applicable for the machine design process and simulations. Furthermore, possible methods for iron loss measurements in electrical machines are pre...

Abstract We report studies on the effect of substituting magnetic Fe 3+ cations with nonmagnetic Al in Y-type hexaferrite Ba 0.5 Sr 1.5 Zn 2 11.92 0.08 O 22 powders their properties and especially phase transitions responsible for observing magnetoelectric effect. In this research, were synthesized by citric acid sol-gel auto-combustion. After auto-combustion process, precursor annealed at 1170...

Leptospirosis is a re-emerging tropical infectious disease caused by pathogenic Leptospira spp. The different host innate immune responses are partially related to the different severities of leptospirosis. In this study, we employed transcriptomics and cytokine arrays to comparatively calculate the responses of murine peritoneal macrophages (MPMs) and human peripheral blood monocytes (HBMs) to...
