Controle da lagarta do cartucho, Spodoptera frugiperda (J.E. Smith), com o Baculovirus spodoptera, aplicado via água de irrigação.
Testou-se a eficiência de Baculovirus spodoptera no controle da lagarta do cartucho, Spodoptera .frugiperda (JE. Smith), veiculado através de água de irrigação. As aplicações foram feitas com um aplicador portátil de produtos químicos acoplado à rede de irrigação e aspersores setoriais ZAS-30. No primeiro experimento, os tratamentos consistiam em lâminas de água de 3, 5 e 7 mm, doses de 1,0 x 105: 6,0 x 104 e 4,0 x 104 poliedros/ml, resultantes da maceração de lagartas. Cem larvas foram amestradas de cada parcela durante três dias, conduzidas para o laboratório, alimentadas com dieta artificial e acondicionadas em copo
Efeito da mistura do Baculovirus spodoptera com inseticidas químicos em subdoses, aplicados via água de irrigação, na mortalidade da Spodoptera frugiperda.
The forward- and the equity-premium puzzles: two symptoms of the same illness?
Using information on US domestic financial data only, we build a stochastic discountfactor—SDF— and check whether it accounts for foreign markets stylized factsthat escape consumption based models. By interpreting our SDF as the projection ofa pricing kernel from a fully specified model in the space of returns, our results indicatethat a model that accounts for the behavior of domestic assets goes a long waytoward accounting for the behavior of foreign assets prices. We address predictabilityissues associated with the forward premium puzzle by: i) using instruments that areknown to forecast excess returns in the moments restrictions associated with Eulerequations, and; ii) by pricing Lustig and Verdelhan (2007)’s foreign currency portfolios.Our results indicate that the relevant state variables that explain foreign-currencymarket asset prices are also the driving forces behind U.S. domestic assets behavior.
Hierarchical Spatial Organization of Geographical Networks
In this work we propose the use of a hirarchical extension of the
polygonality index as a means to characterize and model geographical networks:
each node is associated with the spatial position of the nodes, while the edges
of the network are defined by progressive connectivity adjacencies. Through the
analysis of such networks, while relating its topological and geometrical
properties, it is possible to obtain important indications about the
development dynamics of the networks under analysis. The potential of the
methodology is illustrated with respect to synthetic geographical networks.Comment: 3 page, 3 figures. A wokring manuscript: suggestions welcome
