In order to reduce the operating temperature of solid oxide fuel cells (SOFCs), novel electrolyte materials based on CeO2 and BaCeO3 are being developed in the scientific realm. In this context, we propose a new methodology for preparing the nano-ceramic composite materials such as BaCe0.9Gd0.9O3-δ – Ce0.9Gd0.9O2-δ (BCGO–CGO) and BaCe0.8Sm0.2O3-δ – Ce0.8Sm0.2O2-δ (BCSO – CSO) as possible elec...
We determine that the connectivity and the edgeconnectivity of the Cartesian product G1 × G2 of two strongly connected and finite digraphs G1 and G2 are equal to min{n1κ2,n2κ1, δ+ 1 + δ+ 2 , δ− 1 + δ− 2 } and min{n1λ2,n2λ1, δ+ 1 + δ+ 2 , δ− 1 + δ− 2 }, respectively, where ni , κi , λi , δ + i , δ − i are the order, the connectivity, the edgeconnectivity, the minimum out-degree and the minimum i...
Background During fluid challenge, volume expansion (VE)-induced increase in cardiac output (Δ VE CO) is seldom measured. Methods In patients with shock undergoing strictly controlled mechanical ventilation and receiving VE, we assessed minimally invasive surrogates for Δ VE CO (by transthoracic echocardiography): fluid-induced increases in end-tidal carbon dioxide (Δ VE E'CO2 ); pulse (Δ VE ...
Say that κ’s measurability is destructible if there exists a <κ-closed forcing adding a new subset of κ which destroys κ’s measurability. For any δ, let λδ =df The least beth fixed point above δ. Suppose that κ is indestructibly supercompact and there is a measurable cardinal λ > κ. It then follows that A1 = {δ < κ | δ is measurable, δ is not a limit of measurable cardinals, δ is not δ+ strongl...
2 ∥∥∥(x∗ − x̃) + σ n z̃− δ∥∥2l2 s.t. δ ∈ C − x̃. Letting R1 and R2 denote orthogonal subspaces that contain Q1 and Q2, i.e., Q1 ⊆ R1 and Q2 ⊆ R2, and letting δ = PR1(δ), δ (2) = PR2(δ), δ̂ (1) n (C) = PR1(δ̂n(C)), δ̂ (2) n (C) = PR2(δ̂n(C)) denote the projections of δ, δ̂n(C) onto R1, R2, we can rewrite the above reformulated optimization problem as: [ δ̂ (1) n (C), δ̂ (2) n (C) ] = arg min δ∈Q1,δ∈Q2 1 2...
This paper investigates the principles ta λ,δ, weakenings of λ which allow δ many clubs at each level but require them to agree on a tail-end. First, we prove that ta λ,<ω implies λ. Then, by forcing from a model with a measurable cardinal, we show that λ,2 does not imply ta λ,δ for regular λ, and ta δ+,δ does not imply δ+,<δ. With a supercompact cardinal the former result can be extended to si...
An independent dominating set of a graph, also known as maximal set, is S pairwise non-adjacent vertices such that every vertex not in adjacent to some S. We prove for Δ=4 or Δ≥6, connected n-vertex graph maximum degree at most Δ has an size (1−Δ⌊Δ2/4⌋+Δ)(n−1)+1. In addition, we characterize all graphs having the equality and show other have (1−Δ⌊Δ2/4⌋+Δ)n.
the composition of essential oil of leaves of the male and female shrubs of juniperus chinensis l. (growing in isfahan) was analyzed by gas choromatography(gc) and gc-mass spectrometery (ms). the main constituents of leaf oil of the male shrub were: bornyl acetate (26.1%), sabinene (18.3%), trans-sabinyl acetate (11.1%), myrcene (9.2%), limonene (6.1%), elemol (5.5%), α-cadinol (2.3%), δ-cadine...
