Rotas de síntese e a homogeneidade dos precursores de mulita e cordierita Routes of synthesis and the homogeneity of mullite and cordierite precursors

open access: yesQuímica Nova, 1998
Multicomponent ceramics are mainly synthesized by conventional solid-state reaction route and sol-gel routes. In the sol-gel route, colloidal or polymeric gel are envolved.

Homogeneity of Bilayer Graphene

open access: yes, 2012
We present non-linear transport measurements on suspended, current annealed bilayer graphene devices. Using a multi-terminal geometry we demonstrate that devices tend to be inhomogeneous and host two different electronic phases next to each other.

Homogeneity, Flatness and "Large" Extra Dimensions [PDF]

open access: yes, 2001
We consider a model in which the universe is the direct product of a (3+1)-dimensional Friedmann, Robertson-Walker (FRW) space and a compact hyperbolic manifold (CHM). Standard Model fields are confined to a point in the CHM (i.e. to a brane).

Are cryptocurrencies homogeneous? [PDF]

open access: yesEuropean Financial Management, 2019
AbstractThis article investigates if cryptocurrencies returns' are similarly affected by a selection of demand‐ and supply‐side determinants. Homogeneity among cryptocurrencies is tested via a least absolute shrinkage and selection operator (LASSO) model where determinants of Bitcoin returns are applied to a sample of 12 cryptocurrencies.

Formation and Evaluation of Complete Blood Count Proficiency Testing Program

open access: yesHematology Reports, 2022
Introduction: The haematology external quality assessment (EQA) scheme is the most commonly used service of quality assurance. The provision of complete blood count (CBC) materials must meet the quality requirements at a reasonable cost.

Graded bundles and homogeneity structures

open access: yes, 2011
We introduce the concept of a graded bundle which is a natural generalization of the concept of a vector bundle and whose standard examples are higher tangent bundles T^nQ playing a fundamental role in higher order Lagrangian formalisms.

Assouad type dimensions and homogeneity of fractals [PDF]

open access: yes, 2013
We investigate several aspects of the Assouad dimension and the lower dimension, which together form a natural `dimension pair'. In particular, we compute these dimensions for certain classes of self-affine sets and quasi-self-similar sets and study ...

Enhancing the Microparticle Deposition Stability and Homogeneity on Planer for Synthesis of Self-Assembly Monolayer

open access: yesNanomaterials, 2018
The deposition stability and homogeneity of microparticles improved with mask, lengthened nozzle and flow rate adjustment. The microparticles can be used to encapsulate monomers, before the monomers in the microparticles can be deposited onto a substrate

Spatial-temporal tendencies of the ice regime of the Dnipro Cascade reservoirs

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія, 2023
Formulation of the problem. Knowledge about the formation, destruction and trends of the ice regime of rivers and reservoirs is very important for hydropower, shipping, fisheries, etc.

Leibniz's Laws of Continuity and Homogeneity

open access: yes, 2012
We explore Leibniz's understanding of the differential calculus, and argue that his methods were more coherent than is generally recognized. The foundations of the historical infinitesimal calculus of Newton and Leibniz have been a target of numerous ...
