I prove that in a tree in which the distance between any two endpoints is even, there is a maximum proper partial 0 − 1 coloring such that the edges colored by 0 form a maximum matching.

A new family of phosphorus dendrimers containing on their surfaces 3, 6, 12, and 96 15-membered azamacrocycles has been synthesized. The coordinating ability of these macrocycles to palladium(0) atoms allowed the preparation of new dendrimers of several generations containing the corresponding metal complexes and several new nanoparticulated materials, where nanoparticles are stabilized mainly ...

Efficient stratagems are developed for numerically evaluating oneand two-dimensional integrals over x, y with integrand exp( — x — y)I0(2Jpxy ). The integrals are expressed in terms of convergent series, which exhibit the correct limiting behavior, and which can be evaluated recursively. The performances of these stratagems are compared with numerical integration.

The class of countably intersected families of sets is defined. For any such family we define a Banach space not containing l(N). Thus we obtain counterexamples to certain questions related to the heredity problem for W.C.G. Banach spaces. Among them we give a subspace of a W.C.G. Banach space not containing l(N) and not being itself a W.C.G. space. INTRODUCTION In the present paper we deal wit...

In this paper we investigate those extensions of the bimodal provability logicCSM0 (alias PRL1 or F ) which are subframe logics, i.e. whose general frames are closed under a certain type of substructures. Most bimodal provability logics are in this class. The main result states that all nitely axiomatizable subframe logics containing CSM0 are decidable. We note that, as a rule, interesting syst...

Ceramides containing either sphingosine or sphinganine and one of the 2-hydroxy acids, 14h:0, 16h:0, 18h:0, 20h:0, 22h:0, 24h:0, and 26h:0 were prepared and separated by gas chromatography as the 1,3,2'-tri-O-tri-methylsilyl derivatives. Mass spectrometric analyses of these derivatives showed that the ions formed on electron impact can be used to determine unequivocally the structures of the lo...

We evaluated the preferences of nursery pigs for diets containing increasing distillers dried grains with solubles (DDGS), varying in color, or high-protein distillers dried grains (HP-DDG) and the effects of flavor supplementation on pig preference and growth performance. In Exp. 1 through 5, diet preference was determined in weanling pigs adjusted to a commercial diet for at least 10 d, and t...

We conducted two experiments to study the effects of pelleting and pellet conditioning temperature on weanling pig performance. In Exp. 1, 252 weanling pigs (PIC, L326 x C22) averaging 6.0 +/- 1.3 kg and 21 +/- 3 d of age were used to evaluate six corn-soybean meal-based diets containing 15% dried whey and formulated to contain 1.4% lysine. Treatments consisted of a control diet without spray-d...

A highly selective Ru(3)(CO)(12)-catalyzed deuteration method using t-BuOD as deuterium source is reported. Electron-rich and electron-poor N-heteroarenes such as indoles, azaindoles, deazapurines, benzimidazole, quinolines, isoquinolines, and pyridines were efficiently deuterated at specific positions with high selectivity; in most cases, deuterium incorporation was close to the theoretically ...
