Nonconservative mechanical systems with nonholonomic constraints

引用

Science china(Physics,Mechanics & Astronomy) 2012年第8期55卷 1475-1484页

作者： KRUPKOV olga Department of Mathematics Faculty of Science The University of Ostrava 30. dubna 22 701 03 Ostrava Czech Republic Department of Mathematics and Statistics La Trobe University Melbourne Victoria 3086 Australia

A geometric setting for generally nonconservative mechanical systems on fibred manifolds is proposed. Emphasis is put on an explicit formulation of nonholonomic mechanics when an unconstrained Lagrangian system moves in a generally non-potential force field depending on time, positions and velocities, and the constraints are nonholonomic, not necessarily linear in velocities. Equations of motion, and the corresponding Harniltonian equations in intrinsic form are given. Regularity conditions are found and a nonholonomic Legendre transformation is proposed, leading to a canonical form of the nonholonomic Hamiltonian equations for nonconservative systems.

Rare earth oxides in zirconium dioxide:How to turn a wide band gap metal oxide into a visible light active photocatalyst

引用

Journal of Energy chemistry 2017年第2期26卷 270-276页

作者： chiara Gionco Maria c.Paganini Elio Giamello olga Sacco Vincenzo Vaiano Diana Sannino Department of chemistry University of Torino Department of Industrial Engineering University of Salerno

In the present study, we investigated the effect of cerium and erbium doping of the zirconium dioxide matrix. We synthesized doped samples using hydrothermal process. The amounts of dopant used were 0.5%, 1% and 5% molar(rare earth oxide over zirconium dioxide) respectively. The samples have been studied via X-ray Diffraction measurements for the structural characterization. UV visible diffuse reflectance was used for the optical analysis, Brunauer-Emmett-Teller(BET) model for the measurement of the surface area. Finally the samples have been analysed via electron paramagnetic resonance(EPR) for the electronic characterization. Then we tested the new synthetized materials to determine their photocatalytic activity in the reaction of degradation of methylene blue performed under irradiation by diodes(LEDs) emitting exclusively visible light.

Estrogen, estrogen receptors, and hepatocellular carcinoma: Are we there yet?

引用

World Journal of Gastroenterology 2018年第1期24卷 1-4页

作者： olga A Sukocheva School of Health Sciences Flinders University of South Australia

A protective role of the sex steroid hormone estrogenin hepatocellular carcinoma(Hcc) was suggested a few decades ago according to clinical data showing higher Hcc morbidity and mortality among males. Several recent studies further confirmed the anti-cancer effects of estrogen in the liver. However, it remains to be identified how to exploit estrogen signalling within clinical settings for Hcc treatment. There are several unresolved issues related to the estrogen pathway in liver cells. The main problems include the absence of a clear understanding of which estrogen receptor(ER) isoform is predominantly expressed in normal and malignant liver cells, the ER isoform expression difference between males and females, and which ER isoform should be targeted when designing Hcc therapy. Some of those questions were recently addressed by Iyer and coauthors. The current editorial review critically analyses the study by Iyer et al(WJG, 2017) that investigated the expression of ER subtypes in liver samples collected from patients with a healthy liver, hepatitis c virus cirrhosis, and Hcc. ER presence was evaluated in association with gender, intracellular localization, inflammation marker NF-kB, and proliferation-related effector cyclin D1. The study limitations and advantages are discussed in light of recent advances in the Hcc and estrogen signalling areas.

Influence of the type and quantity of polyolefin fibers on the strength properties(compression strength, tensile strength in bending, strength in uniaxial tension), the deformation properties(elastic modulus, Poisson’s coefficient) and the abrasion resistance of cement concrete with water-to-cement ratio within 0.31 e0.55 were stated in the *** ways of fibers introduction into fresh concrete were investigated. It was shown that the fibers introduction method and procedure of mixing are the ways to improve the fibers uniform distribution in fresh concrete. The increase of the bending tensile strength and the uniaxial tensile strength of concrete with fibers reinforcement in comparison with the reference concrete was observed with the water-to-cement ratio decrease. The increase of uniaxial tensile strength at age of 28 days for concrete with macrofibers in amount of4.5 kg/m^3 was 23% and 29%;for macrofibers in quantity of 3 kg/m^3 was 19% and 26% with water-cement ratio equal to 0.49 and 0.31, respectively. The maximum reduction of abrasion in the range of 7.5%e10% was observed in concrete with water-to-cement ratio within0.44 e0.55 for all investigated types of fibers. The influence of fibers on the concrete abrasion with lower W/c ratio was negligible. The results can contribute to the rational use of modified polyolefin fibers in road pavement concrete.
