Several important empirical studies (for example, Altonji, Hayashi, and Kotlikoff, 1992, 1996, 1997) have found that households are not altruistically linked in a way consistent with the standard Ricardian model, as put forward by Barro (1974). We built a two-sided altruistic-linkage model in which private transfers are made in the presence of two types of shocks: an observable shock that is pu...

This work deals with the development of a digital image analysis procedure to characterize microbial flocs obtained in three different WWTP: a bench-scale Sequencing Batch Reactor (SBR) dealing with phenol and nitrogen biological removal, a municipal treatment unit (Ilha do Governador, Rio de Janeiro, Brazil) and an industrial wastewater treatment plant (Ciba – Estrada do Colégio, Rio de Janeir...

Approximations of expressions of the form If := trace(W T f(A)W ), where A ∈ Rm×m is a large symmetric matrix, W ∈ Rm×k with k ≪ m, and f is a function, can be computed without evaluating f(A) by applying a few steps of the global block Lanczos method to A with initial block-vector W . This yields a partial global Lanczos decomposition of A. We show that for suitable functions f upper and lower...

The atom-bond connectivity (ABC) index is one of the most investigated degreebased molecular structure descriptors with a variety of chemical applications. It is known that among all connected graphs, the trees minimize the ABC index. However, a full characterization of trees with a minimal ABC index is still an open problem. By now, one of the proved properties is that a tree with a minimal AB...

The three primate species of Santa Rosa National Park, Costa Rica (Ateles geoffroyi, Alouatta palliata, Cebus capucinus) have diets in which fruits are major components. All three primate species defecated seeds of many fruiting species; the majority of which (60%) germinated under experimental conditions. The sampling of seed traps placed throughout he forest indicated that, on average, 392 la...
