1. Humic substances and its distribution in coffee crop under cover crops and weed control methods
ABSTRACT Humic substances (HS) comprise the passive element in soil organic matter (SOM), and represent one of the soil carbon pools which may be altered by different cover crops and weed control methods. This study aimed to assess HS distribution and characteristics in an experimental coffee crop area subjected to cover crops and cultural, mechanical, and c

2. Métodos para resgate, conservação e multiplação em larga escala de matrizes de Eucalyptus benthamii Maiden &Cambage / Methods for rescue, conservation and multiplication of matrices Eucalyptus benthamii Maiden &Cambege
The E. benthamii presents a great aptitude for cultivation in Brazil, especially in cold climates and with frequent frosts, this is due to your west of Sydney origin in Australia, where temperatures are very low, with frosts. Taking into account their optimal silvicultural performance, selected genotypes will certainly represent an excellent alternative for

3. Mechanized methods for harvesting residual biomass from Mediterranean fruit tree cultivations
This study evaluates the technology and work systems used in order to harvest residual biomass from pruning in the specific conditions of Mediterranean fruit orchards (narrow distances between crop-rows). Harvesting has been divided into several types of operations - pruning, biomass alignment between crop tracks, biomass concentration in piles, chipping and

4. Diâmetro de coroamento e métodos de controle de plantas daninhas no crescimento do eucalipto em sistema silvipastoril / Crown diameter and methods of weed control in the growth of eucalyptus trees in silvopastoral system
Objetivou-se avaliar a interferência do método de controle, do diâmetro de coroamento e da desrama precoce sobre o crescimento inicial de eucalipto em Sistema Silvipastoril, visando fornecer subsídios para a elaboração de estratégias de controle voltadas para o Manejo Integrado de Plantas Daninhas. Foram realizados dois experimentos: no primeiro, aval

5. Pruning cycles and nitrogen fertilization of coffee feilds conducted in the "safra zero" system.
Modern, competitive and cost effective coffee production requires plants with high productivity that are more adapted to mechanical and manual harvesting. ?Safra Zero? is a cultivation system designed to limit plant height and eliminate the need for expensive harvesting during years of low productivity, which usually follow years of high productivity. This s

7. Prácticas culturales para el manejo de la Sigatoka negra en bananos y plátanos
Black sigatoka (Mycosphaerella fijiensis) control consists in the continuous use of fungicide sprays and cultural practices. Cultural control reduces inoculum sources of the pathogen and favorable environmental conditions for its development, as well as it increases the vigor of the plants. In order to manage the disease it is necessary to know its behavior

8. Identificação de Madeiras de clones de Eucalyptus grandis, Eucalyptus urophylla e do híbrido Eucalyptus urograndis por RMN 13C. / Wood Identification of clones of Eucalyptus grandis, Eucalyptus urophylla and of the hybrid Eucalyptus urograndis by 13C NMR .
The Eucalyptus genus is represented for trees that have high growth rate, plasticity, straight way of stem growth, natural pruning and wood with the technological properties suitable for a diverse use. In function of ecological society pressure and the larger distance between the forest and the consumer center, the native woods have been substituted by eucal

9. Uma contribuiÃÃo ao problema de seleÃÃo de modelos neurais usando o princÃpio de mÃxima correlaÃÃo dos erros / A contribution to the problem of selection of neural models using the beginning of maximum correlation of the errors
PropÃe-se nesta tese um mÃtodo de poda de pesos para redes Perceptron Multicamadas (MLP). TÃcnicas clÃssicas de poda convencionais, tais como Optimal Brain Surgeon(OBS) e Optimal Brain Damage(OBD), baseiam-se na anÃlise de sensibilidade de cada peso da rede, o que requer a determinaÃÃo da inversa da matriz Hessiana da funÃÃo-custo. A inversÃo da ma

10. ProduÃÃo e nutriÃÃo de mudas de pessegueiro em hidroponia. / Production and nutrition of peach seedling in hydroponic
The search for new technologies in modern fruit production has been continuous. That is due to the growing level of demands of the market, which is more and more competitive. Few are the technologic alternatives in the area of seedlings, mainly in temperate climate fruit-bearing plants such as the peach tree. The production of seedlings in hydroponics has be

11. Branch-and-bound method application in a single machine earliness/tardiness scheduling problem with a common due date. / Aplicação do método branch-and-bound na programação de tarefas em uma única máquina com data de entrega comum sob penalidades de adiantamento e atraso.
The objective of this work is to study the single-machine scheduling problem with a common due date. In this case, jobs, after be processed only once in the machine, must be delivered in a common due date and they are penalized of earliness or tardiness according to their completion time. This problem is found in cases of batch production with prespecified c
