in this research, some more applicable ferrofluids are produced and their mechanical specifications are measured, experimentally. also, their treatments in the ventilated cavity geometry are assessed numerically. the magnetite nanoparticles are produced by a chemical combination of fe2+ and fe3+ with nh3. in order to solve the nanoparticles in the new mediums, a proper coating is added to them....

A descoberta de ferramentas associadas à metalurgia e carpintaria na Idade do Ferro bretã é relativamente esparsa. Achados tipo são encontrados em assentamentos, tesouros ocultados e, às vezes, cemitérios. Este artigo aborda a deposição ferramentas, como tenazes, limas, martelos outros, analisando contextos funerários King Harry Lane (Hertfordshire), Whitcombe (Dorset), Rudston Burton Fleming (...

Printed electronics has recently moved from a focus on the production of individual components towards the design and initial commercialization of integrated systems. This paper describes the current status and further trends of ferroelectric nonvolatile memories as developed and produced by Thin Film Electronics. Keywords— Printed memory, ferroelectric, printed transistors, integrated products...

The nuclear spin-lattice relaxation rates 1 / T I were found to be independent of temperature in the paramagnetic states of various kinds of metallic magnets. It has been ascertained from quantitative analyses that the values of 1 / Ti in the weak itenerant ferromagnets and the localized moment systems were explained by the SCR and the HBEN theories of spin fluctuations, respectively. Both theo...

The application of the density-functional theory in the local approximation to magnetic materials is discussed and illustrated by examples. The magnetic properties of the 3d elemental metals as well a s their cohesive properties are described by means of self-consistent local-spin-density (LSD) calculations and by using the LSD-Stoner method. The application of the LSD approximation to narrow-b...

OBJECTIVE The objective of this study was to determine the effect of non-occupational exposure to manganese (Mn) on postural balance. METHODS Residents living near a ferromanganese refinery provided hair and blood samples after postural balance testing. The relationship between hair Mn and postural balance was analyzed with logistic regression. Following covariate adjustment, postural balance...
