1. Phosphate and nitrogen fertilization in the production of Barueiro (Dipteryx alata Vog.) seedlings
Resumo O barueiro (Dipteryx alata Vog.), frutífera nativa do cerrado, tem despertado o interesse de produtores e consumidores devido a suas múltiplas possibilidades de uso. Para a obtenção de mudas de barueiro com qualidade, é fundamental a realização de adubações equilibradas, destacando-se o fornecimento de fósforo e nitrogênio, essenciais para

2. Um novo ecossistema: florestas urbanas construídas pelo Estado e pelos ativistas
resumo Historicamente, a expansão das cidades resultou na substituição da paisagem natural pela urbana, tendo como consequência a degradação ambiental por meio das mudanças na cobertura do solo, nos sistemas hidrológicos, nos ciclos biogeoquímicos, no clima e na biodiversidade, tornando as cidades especialmente vulneráveis às mudanças climáticas

3. Time of metamitron application and concentration in the chemical thinning of ‘Maciel’ peach
Resumo No cultivo de pessegueiros o produtor tem o desafio de obter frutos de boa qualidade e manter a produção de forma equilibrada ao longo dos anos. O raleio favorece esses parâmetros e reduz a carga de frutos nas plantas. O raleio manual praticado comumente em pessegueiros, exige elevada mão de obra e onera os custos de produção. Estudos apontam o

4. Windowing queries: algorithms and data structures. / Consultas de segmentos em janelas: algoritmos e estruturas de dados
In this work we study problems about point and segment query in rectangular windows whose edges are parallel to the axis. Given a set of segments (or points) in the plane. In a first phase these segments are organized in data structures such that queries for segments in windows are done more efficiently. In the second phase windows are given online. The data

5. Identification and partial characterization of SEPALLATA genes in coffee arabica / IdentificaÃÃo e caracterizaÃÃo parcial de genes SEPALLATA em cafà arÃbica
Coffee is one of the most important international commodity, produced in more than sixty countries and it is classified as one of the five agricultural exportation most valued in development countries. One of the biggest difficulties in this crop is the heterogeneity of the flowering process, therefore, imbalance on the fruit maturation, which makes the harv

6. Contribuições para gestão urbana :corredores de vegetação para avifauna em Porto Alegre, RS
Abstract: The green tunnel is a landscape structure specific to urban arborization, formed by the joining of the canopies of trees along the roads. This dense arborization of the roads visually forms a suspended linear mass over the streets, qualifying the environment constructed by the different contributions generated by the presence of vegetation. Based u

7. DBM-Tree: trading height-balancing for performance in metric access methods
Metric Access Methods (MAM) are employed to accelerate the processing of similarity queries, such as the range and the k-nearest neighbor queries. Current methods, such as the Slim-tree and the M-tree, improve the query performance minimizing the number of disk accesses, keeping a constant height of the structures stored on disks (height-balanced trees). How

8. Uma proposta para a triangulação de Delaunay 2D e localização planar de pontos em OCaml
In this thesis, it is presented a planar point location algorithm. The algorithm was developed on top of two elements: - the method of slabs to divide the planar subdivision, is represented by a graph, allowing the fast identification of the region where the point being recalled is; - the Interval Multi-B-tree, a data structure derived from the B-tree, prepa

9. ProteinDBS: a real-time retrieval system for protein structure comparison
We have developed a web server (ProteinDBS) for the life science community to search for similar protein tertiary structures in real time. This system applies computer visualization techniques to extract the predominant visual patterns encoded in two-dimensional distance matrices generated from the three-dimensional coordinates of protein chains. When meanin

10. The Balance of Driving Forces During Genome Evolution in Prokaryotes
Genomes are shaped by evolutionary processes such as gene genesis, horizontal gene transfer (HGT), and gene loss. To quantify the relative contributions of these processes, we analyze the distribution of 12,762 protein families on a phylogenetic tree, derived from entire genomes of 41 Bacteria and 10 Archaea. We show that gene loss is the most important

11. Evolutionary profiles from the QR factorization of multiple sequence alignments
We present an algorithm to generate complete evolutionary profiles that represent the topology of the molecular phylogenetic tree of the homologous group. The method, based on the multidimensional QR factorization of numerically encoded multiple sequence alignments, removes redundancy from the alignments and orders the protein sequences by increasing linear
