Ultra‐high molecular weight polyethylene knee prostheses of two different sizes (i.e. characterised by different contact areas) were run on a knee wear simulator in two tests differing for the applied load. Gravimetric and micro‐Raman spectroscopic analyses were performed to investigate at macroscopic and molecular levels the effects of contact area and applied load on the morphology of the knee components. The larger prostheses showed a higher mass loss in both tests, while Raman spectroscopy showed ...

Benzene and substituted benzenes XC6H5 (X = CH3, F, Cl, Br, NO2) are hydroxylated to the corresponding monophenols by H2O2 in CH3CN in the presence of catalytic amounts of VO (O2) (PIC) (H2O)2 where PIC is the anion of picolinic acid. Fair yields of hydroxylated materials are obtained by adding the oxidant in portions, or continuously, and keeping the conversion of the substrate rather low (<3%). Although some degradation of the catalyst takes place during the reaction, such a process can be minimized by ...

Nowadays the most important issues for commercial SOFC systems are related to their durability and stability of performance both of which are affected by fuel feeding composition. The trace compounds contained in biogenous fuels can interact with SOFC components causing evident drops in performance and severely reducing the lifetime of the entire system. Due to the significant impact on SOFC performance from widely varying fuel inputs, the influence of trace compounds should be investigated in real ...

We apply the technique of convex integration to obtain non-uniqueness and existence results for power-law fluids, in dimension d≥3 . For the power index q below the compactness threshold, i.e. q∈(1,2dd+2) , we show ill-posedness of Leray-Hopf solutions. For a wider class of indices q∈(1,3d+2d+2) we show ill-posedness of distributional (non-Leray-Hopf) solutions, extending the seminal paper of Buckmaster & Vicol [10]. In this wider class we also construct non-unique solutions for every datum in L2 .

We construct infinitely many incompressible Sobolev vector fields $u \in C_t W^{1,\tilde p}_x$ on the periodic domain $\mathbb{T}^d$ for which uniqueness of solutions to the transport equation fails in the class of densities $\rho \in C_t L^p_x$, provided $1/p + 1/\tilde p > 1 + 1/d$. The same result applies to the transport-diffusion equation, if, in addition $p'<d$.

The mechanical failure of one cell is sufficient to lead to the end of service of a solid oxide fuel cell (SOFC) stack. Therefore, there is growing interest in gaining knowledge on the mechanical properties of the cell materials for stress analysis. This study compiles available data from the literature on the mechanical properties of the most common materials used in intermediate-temperature anode-supported cells: nickel and yttria-stabilized zirconia (Ni–YSZ) anodes, YSZ electrolytes, yttria (YDC) ...

Anode-supported cells (ASC) are considered as a promising SOFC technology for achieving higher power densities at significantly reduced operating temperatures. Thereby it is commonly expected to enhance both the profitability and durability of fuel cell systems in real world applications. In the collaborative project LOTUS, a micro-CHP system prototype will be developed and tested based on a novel ASC technology with an operating temperature of 650 °C. Extended system design considerations are required ...

One of the major limitations of the nickel (Ni) – yttria-stabilized zirconia (YSZ) anode support for solid oxide fuel cells (SOFC) is its low capability to withstand transients between reducing and oxidizing atmospheres ("RedOx" cycle), owing to the Ni-to-NiO volume expansion. This work presents results on different anode supports fabricated by tape casting. Three compositions are prepared, as the outcome of a preceding design of experiment approach. The NiO proportion is 40, 50 and 60 wt% of the anode ...

The common technology for solid oxide fuel cells (SOFC) is based on a cermet (ceramic–metal composite) anode of nickel with yttria stabilized zirconia (YSZ), often used as the supporting structure. One of the main limitations of this technology is the tolerance of the anode towards reduction and oxidation ("RedOx") cycles. In this study, two techniques are used to quantify the anode expansion after a RedOx cycle of the nickel at different temperatures. The first method considers the anode expansion above ...

The oxidation kinetics of non‐oxides depend on the inward diffusion of oxygen from the environment through the passivating silica overgrowth, the outward diffusion of the effluent species, e.g., CO, produced by the oxidation reaction at the interface, and the chemical driving forces for diffusion. An analysis that combines these factors into a unified theory is presented. The analysis is applied to experiments on the oxidation of polymer‐derived amorphous silicon oxycarbide (SiCO) ceramics containing ...

In this letter, we report the formation of bulk samples of silica-based glass containing Si nanocrystals (Si-ncs) by pyrolysis of a preceramic precursor. The starting precursor is a sol–gel-derived polysiloxane containing only Si–H groups which leads, after annealing in a controlled atmosphere in the range 1000–1200 °C, to the precipitation of Si-ncs. Characterization of the nanostructure was performed by x-ray diffraction and Raman scattering analyses. Room-temperature luminescence experiments show ...

Silicon oxycarbide (SiOC) glasses with controlled amounts of Si—C bonds and free carbon have been produced via the pyrolysis of suitable preceramic networks. Their chemical durability in alkaline and hydrofluoric solutions has been studied and related to the network structure and microstructure of the glasses. SiOC glasses, because of the character of the Si—C bonds, exhibit greater chemical durability in both environments, compared with silica glass. Microphase separation into silicon carbide (SiC), ...

Estrogen and progesterone receptor status was reviewed in 405 patients from prior adjuvant breast cancer trials at the University of Verona. Only 233 patients were actually examined with respect to hormone status and outcome. No relationship between hormone receptor status and most of the commonly followed prognostic signs, i.e. tumor size, nodal status, and age, was found. Overall survival was correlated with hormone receptor positivity for patients with more than 4 positive axillary nodes. Disease- ...

The authors report on a consecutive retrospective series of 150 male breast cancers. Clinical, diagnostic and therapeutic features are compared over time and with respect to a large consecutive series of female breast cancers. Both age at diagnosis and tumor stage were more advanced in males than in females. Poor alertness of both men and doctors for this infrequent disease may account for such a delay in diagnosis. The use of mammography increased over time and sonography or cytology were frequently ...

A multicenter series of 350 intraductal breast cancers (DCIS) is reported. Mammography was the most sensitive test but suspicion arose only at palpation in 13% of cases whereas in 10% of cases biopsy was recommended for a benign lesion and DCIS was an unexpected finding. Mammography, physical examination and cytology must be combined to achieve optimal sensitivity. Systematic biopsy of apparently benign masses would increase DCIS detection rates but the cost-effectiveness of such a policy is questionable. ...

Ion beam analysis was applied for the first time to characterize the oxidation process of silicon oxycarbides (SiCO) glasses (belonging to the class of polymer-derived ceramics). The technique unveiled the structure of the interface between the silica scale and the SiCO substrate. At the early oxidation stage, a smooth concentration profile was observed between the surface silica layer and the substrate. The role of the free carbon on the kinetics of the oxidation process was studied by preparing ...

We prove a quadratic interaction estimate for approximate solutions to scalar conservation laws obtained by the wavefront tracking approximation or the Glimm scheme. This quadratic estimate has been used in the literature to prove the convergence rate of the Glimm scheme. The proof is based on the introduction of a quadratic functional 𝔔(t), decreasing at every interaction, and such that its total variation in time is bounded. Differently from other interaction potentials present in the literature, ...
