Nutrição mineral de hortaliças: LV - desenvolvimento dos frutos da cultura de pepino (Cucumis sativus L.) var. Aodai e exportação de nutrientes através da colheita

Este trabalho foi realizado com os seguintes objetivos: determinar a evolução e produção dos frutos de pepino (Cucumis sativus L.) var. Aodai em função do desenvolvimento da planta, analisar as concentrações dos nurientes no fruto no ponto de consumo e calcular as quantidades de nutrientes exportados pela colheita dos frutos. Verifica-se que as quantidades de nutrientes exportados através da colheita, por tonelada de frutos no ponto de consumo, correspondem a: K -1.617 g, N-1.050 g; P-200 g; Ca -174 g; Mg-139 g; Fe-1,91 g; Zn -1,21 g; Mn-0,98 g; B-0,87g; Cu-0,52g.

Scoring rules on dichotomous preferences

In this paper, we study individual incentives to report preferences truthfully for the special case when individuals have dichotomous preferences on the set of alternatives and preferences are aggregated in form of scoring rules. In particular, we show that (a) the Borda Count coincides with Approval Voting on the dichotomous preference domain, (b) the Borda Count is the only strategy-proof scoring rule on the dichotomous preference domain, and (c) if at least three individuals participate in the election, then the dichotomous preference domain is the unique maximal rich domain under which the Borda Count is strategy-proof.

Bidding at sequential first-price auctions with(out) supply uncertainty: a laboratory analysis

We report on a series of experiments that test the effects of an uncertain supply on the formation of bids and prices in sequential first-price auctions with private-independent values and unit-demands. Supply is assumed uncertain when buyers do not know the exact number of units to be sold (i.e., the length of the sequence). Although we observe a non-monotone behavior when supply is certain and an important overbidding, the data qualitatively support our price trend predictions and the risk neutral Nash equilibrium model of bidding for the last stage of a sequence, whether supply is certain or not. Our study shows that behavior in these markets changes significantly with the presence of an uncertain supply, and that it can be explained by assuming that bidders formulate pessimistic beliefs about the occurrence of another stage.

On Boas-Type Problem

R.P. Boas has found necessary and sufficient conditions of belonging of function to Lipschitz class. From his findings it turned out, that the conditions on sine and cosine coefficients for belonging of function to Lip α(0 & α & 1) are the same, but for Lip 1 are different. Later his results were generalized by many authors in the viewpoint of generalization of condition on the majorant of modulus of continuity. The aim of this paper is to obtain Boas-type theorems for generalized Lipschitz classes. To define generalized Lipschitz classes we use the concept of modulus of smoothness of fractional order.
