Water management for establishment of alfafa (Medicago sativa L.).

This research was carried out in 1997, at the Centro de Ciencias Agrarias of the Universidade Federal de Sao Carlos, in Araras, SP, Brazil, to evaluate the behavior of theree growth stages ( S1= initial vegetative stage, s2 = full vegetative stage, and s3= reprodutive stage) of the Crioula alfafa cultivar, in the presence of four water levels (L1=100%, L2=80%, L3= 45-50% and, L4=20-25% of a sprinkler irrigation) in a field trial. Growth stages changed according to water levels, and s2stage was the most affected bywater supply, while s1, was the least one and water showed to be a negative factor to plant establishment

Water Management for Establishment of Alfalfa (\u3ci\u3eMedicago sativa\u3c/i\u3e L.)

This research was carried out in 1997, at the “Centro de Ciências Agrárias” of the “Universidade Federal de São Carlos”, in Araras, SP, Brazil, to evaluate the behavior of three growth stages (S1 = initial vegetative stage, S2 = full vegetative stage, and S3 = reproductive stage) of the “Crioula” alfalfa cultivar, in the presence of four water levels (L1 = 100%, L2 = 80%, L3 = 45-50% and, L4 =20-25% of a sprinkler irrigation) in a field trial. Growth stages changed according to water levels, and S2 stage was the most affected by water supply, while S1 was the least one and water showed to be a negative factor to plant establishment

Combinatorial Assortment Optimization

Assortment optimization refers to the problem of designing a slate of products to offer potential customers, such as stocking the shelves in a convenience store. The price of each product is fixed in advance, and a probabilistic choice function describes which product a customer will choose from any given subset. We introduce the combinatorial assortment problem, where each customer may select a bundle of products. We consider a model of consumer choice where the relative value of different bundles is described by a valuation function, while individual customers may differ in their absolute willingness to pay, and study the complexity of the resulting optimization problem. We show that any sub-polynomial approximation to the problem requires exponentially many demand queries when the valuation function is XOS, and that no FPTAS exists even for succinctly-representable submodular valuations. On the positive side, we show how to obtain constant approximations under a "well-priced" condition, where each product's price is sufficiently high. We also provide an exact algorithm for $k$-additive valuations, and show how to extend our results to a learning setting where the seller must infer the customers' preferences from their purchasing behavior

MatchMaking – A Tool to Match OWL Schemas

This paper describes a software tool that implements an instancebased schema matching technique for OWL dialects. The technique is based on a matching algorithm that depends on the definition of similarity functions that evaluate the semantic proximity of elements from two different schemas. The tool is engineered to accommodate different similarity functions and variations of the matching algorithm, thereby facilitating experimentation with alternative setups

Da progressão dos costumes à história natural da humanidade: reflexões escocesas sobre a temporalidade histórica

At the second half of the eighteenth century, Scottish thinkers David Hume, William Robertson,Adam Smith, Lord Kames (Henry Home), and Adam Ferguson wrote extensively on the stages ofhuman society, from its origins to civilisation. These works fashioned a typically Scottishhistoriographical genre, the ‘Natural history of mankind’. This genre, intimate of the Age ofEnlightenment in its Scottish form, divided the evolution of mankind in stages and establishedmoral values for each one. Here, my goal is to draw a summary of this historiographical trend.Durante a segunda metade do século dezoito, intelectuais escoceses como David Hume, William Robertson, Adam Smith, Lorde Kames (Henry Home) e Adam Ferguson refletiram, longamente, sobre as fases do desenvolvimento da humanidade, desde suas origens até o estabelecimento da civilização. Essa reflexão tomou a forma de um gênero historiográfico tipicamente escocês, a “história natural da humanidade”. Inseparável do contexto iluminista da época, a história natural escocesa dividiu a evolução da sociedade em etapas e estabeleceu valores morais para cada uma delas. Neste artigo, buscamos traçar um breve panorama dessa linha historiográfica
