1. Correlation maps to assess soybean yield from EVI data in Paraná State, Brazil
ABSTRACT Vegetation indices are widely used to monitor crop development and generally used as input data in models to forecast yield. The first step of this study consisted of using monthly Maximum Value Composites to create correlation maps using Enhanced Vegetation Index (EVI) from Moderate Resolution Imaging Spectroradiometer (MODIS) sensor mounted on Ter

2. Effect of seminal plasma and egg yolk concentration on freezability of goat semen
The objective of this study was to evaluate the effects of egg yolk and seminal plasma on the viability of cryopreserved goat semen. To this end, four fertile Saanen bucks, aged between 10 months and 1 year, and weighing 18 to 25 kg, were used. Semen was collected from each buck by the artificial vagina method at the end of breeding season (June-July). The e

3. Otimização multiperíodo por média-variância sem posições a descoberto em ativos de risco. / Mean-variance multiperiod optimization with no-shorting constraints in risk assets.
Initially in this work are presented the basics concepts of mean and variance and how they are applied to quantify an asset or a portfolio. After this we present the optimal investment strategy of the Markowitz no-shorting constraints mean-variance portfolio selection in single period and the Markowitz optimal investment strategy without such constrain.

4. AUTOCALIBRATION OF FREQUENCY STANDARDS USING THE INTERNET / CALIBRACIÓN AUTOMÁTICA DE PADRONES DE TIEMPO Y FRECUENCIA VÍA INTERNET / CALIBRAÇÃO AUTOMÁTICA DE PADRÕES ATÔMICOS DE TEMPO E FREQÜÊNCIA VIA INTERNET
A calibração de padrões atômicos de tempo e freqüência, na forma atualmente realizada, apresenta o inconveniente de ter que se fazer o transporte do Padrão de Transferência até os laboratórios onde se encontram os padrões a serem calibrados. Isto se dá pelo fato destes laboratórios não possuírem uma maneira adequada para enviarem seus padrões
