Dibromination of [2.2]paracyclophane (I) led to predominantly pseudo-ortho2 (11) and pseudo-para2 (111) disubstituted compounds, and to lesser amounts of pseudo-meta (IV) and para (V) isomers. Oxidation of these dibromides gave terephthalic acids whose esters were identified by vpc, and whose structures allowed homoannular and transannular bromination to be differentiated. Tetrabromination of I...

The procedure for the iterative unification of decision-makers' opinions is proposed. Since the adaptability of a quantitative model and comparability of individual group members' results are required, it is based on the alternative sorting analysis restricted by the localization principle. It is capable of the automatic adjustment of preferential parameters, which are in accordance with the ps...

The present paper reviews activity in environmental valuation by examining trends in publication rates over the past three decades. It also provides an overview of the demand for environmental valuation by academic markets and by policy markets. The results of this historical analysis suggest that there is not as much use of environmental valuation in policy analysis as could be expected given ...

In this paper,  pseudo-amenability and pseudo-Connes amenability of weighted semigroup algebra $ell^1(S,omega)$ are studied. It is proved that pseudo-Connes amenability and pseudo-amenability of weighted group algebra $ell^1(G,omega)$ are the same. Examples are given to show that the class of $sigma$-Connes amenable dual Banach algebras is larger than that of Connes amenable dual Banach algebras.

A conjecture of G. McGarvey for the 2-adic valuation of the Schenker sums is established. These sums are n! times the sum of the first n+1 terms of the series for e. A certain analytic expression for the p-adic valuation of these sums is provided for a class of primes. Some combinatorial interpretations (using rooted trees) are furnished for identities that arose along the way.

Let f1 (resp. f2) denote two (elliptic) newforms of prime level N , trivial character and weight 2 (resp. k + 2, where k ∈ {8, 12}). We provide evidence for the Bloch-Kato conjecture for the motive M = ρf1⊗ρf2 (−k/2−1) by proving that under some assumptions the p-valuation of the order of the Bloch-Kato Selmer group of M is bounded from below by the p-valuation of the relevant L-value (a specia...

The construction of these groups is straightforward; to an algebra B we assign the quotient R,,, G,/G,. The main effort comes in showing that these are the only possibilities. The key to this, and the basic technical idea in the paper, is the use of N&on blow-ups of group schemes over valuation rings. This process has been used before [ 1, 21 as a tool for resolving singularities, but in fact i...

The Morrison-Kawamata cone conjecture predicts that the actions of the automorphism group on the effective nef cone and the pseudo-automorphism group on the effective movable cone of a klt Calabi-Yau pair (X,∆) have finite, rational polyhedral fundamental domains. Let Z be an n-dimensional Fano manifold of index n − 1 such that −KZ = (n − 1)H for an ample divisor H. Let Γ be the base locus of a...

BACKGROUND There is conflicting evidence as to whether patients with chronic disease value hypothetical health states differently from individuals who have not experienced any long-lasting diseases. Furthermore, most studies regarding this issue have been conducted in western countries, with only one conducted in Asia. We aimed to evaluate possible systematic differences in the valuation of Eur...
