13. DIAGNOSIS AND MODELING OF THE PETROLEUM LOGISTIC NETWORK IN BRAZIL / DIAGNÓSTICO E MODELAGEM DA REDE DE DISTRIBUIÇÃO DE DERIVADOS DE PETRÓLEO NO BRASIL
This master thesis presents a study about the petroleum products distribution system, with the development of a mathematical model for the determination of the logistic costs of strategic oil stocks in Brazil. This model doesn t intend to determine the minimum distribution cost , but establishes a rational distribution of the strategic oil stocks, based in t

14. Methodology for calculation of technical losses in each segment of the distibution system. / Metodologia para cálculo de perdas técnicas por segmento do sistema de distribuição.
This work focuses on the development of a new methodology for calculating technical losses within the different segments of the electric distribution system. In order to evaluate technical losses the electrical system was divided into eight segments: energy meter, customer connections, secondary feeder, distribution transformer, primary feeder, distribution

15. Neutral evolution of mutational robustness
We introduce and analyze a general model of a population evolving over a network of selectively neutral genotypes. We show that the population’s limit distribution on the neutral network is solely determined by the network topology and given by the principal eigenvector of the network’s adjacency matrix. Moreover, the average number of neutral mutant nei

16. Visualization of microtubules in interphase and mitotic plant cells of Haemanthus endosperm with the immuno-gold staining method.
A procedure is presented for the immunocytochemical visualization of microtubules in interphase and mitotic cells of Haemanthus endosperm. It includes preservation of microtubules (MTs) with glutaraldehyde and uses colloidal gold, coated with secondary antibodies, in a novel indirect-light microscopic technique: the immuno-gold staining method. This immunocy

17. Improved prediction of protein secondary structure by use of sequence profiles and neural networks.
The explosive accumulation of protein sequences in the wake of large-scale sequencing projects is in stark contrast to the much slower experimental determination of protein structures. Improved methods of structure prediction from the gene sequence alone are therefore needed. Here, we report a substantial increase in both the accuracy and quality of secondar

18. TopNet: a tool for comparing biological sub-networks, correlating protein properties with topological statistics
Biological networks are a topic of great current interest, particularly with the publication of a number of large genome-wide interaction datasets. They are globally characterized by a variety of graph-theoretic statistics, such as the degree distribution, clustering coefficient, characteristic path length and diameter. Moreover, real protein networks are qu

19. Sensory innervation of baboon muscle spindles.
The number and distribution of primary and secondary sensory endings has been studied in 52 de-efferentated baboon muscle spindles and the axon diameters of the afferent fibres innervating these endings have been measured. Each spindle contained a single primary sensory ending; most of these endings were supplied by a single afferent nerve fibre. Each primar

20. Prediction of protein folding class using global description of amino acid sequence.
We present a method for predicting protein folding class based on global protein chain description and a voting process. Selection of the best descriptors was achieved by a computer-simulated neural network trained on a data base consisting of 83 folding classes. Protein-chain descriptors include overall composition, transition, and distribution of amino aci

21. Thy-1 immunolabeled thymocyte microdomains studied with the atomic force microscope and the electron microscope.
The atomic force microscope (AFM) and the transmission electron microscope (TEM) have been used to study the morphology of isolated mouse thymocyte microdomains and Thy-1 antigen distribution at the surface of these structures. AFM images were recorded in air in the contact mode on membrane vesicles deposited on previously heated tissue culture plastic sheet
