Voyage au Bresil : ou l'on trouve la description du pays, de ses productions, de ses habitants, et de la ville et des provinces de san-salvatore et porto-seguro, avec une table correcte des latitudes et longitudes des ports de la cote du bresil, ainsi qu'un tableau du change, etc

Voyage au Brésil narra a experiência de observar a vida e os costumes dos habitantes do Brasil e oferece um registro cheio de interesse sociológico e até científico. Segundo Rubens Borba de Moraes, " é obra valiosíssima sobre a Bahia colonial", sendo esta edição mais preciosa que a inglesa de 1805. A obra foi traduzida também para o alemão. Afonso de Taunay resume e comenta o livro de Lindley em Aventuras de Thomas Lindley.

Sertum palmarum brasiliensium, ou, Relation des palmiers nouveaux du Brésil : découverts, décrits et dessinés d'après nature

A história Bibliográfica de Sertum palmarum brasiliensium... é a seguinte: em 1900, o Deputado Federal por São Paulo, D. Augusto César Miranda Azevedo, apresentou ao Congresso Nacional uma emenda à proposta orçamentária para 1901, autorizando o Poder Executivo "a mandar imprimir na Imprensa Nacional o texto e as estampas da monografia sobre palmeiras do botânico brasileiro Dr. João Barbosa Rodrigues..." Entretanto, a autorização não pôde ser efetivada porque a Imprensa Nacional não dispunha de equipamento para a reprodução de estampas. Em 1901, o Senador pelo Estado do Pará, Dr. Lauro Sodré, apresentou emenda à proposta orçamentária para 1902, cuja lei estabeleceu no art. 6º : "é o Governo autorizado a mandar imprimir na Europa ou em país onde houver mais vantagem, a obra Sertum palmarum..., abrindo para tal fim o necessário crédito, e de acordo com o autor". O crédito -- duzentos contos de réis -- foi finalmente, aberto o Decreto nº 4.428, de 12 de junho de 1902, assinado por Campos Sales e referendado por Sabino Barroso, Ministro da Justiça. A obra foi impressa em Bruxelas sob a direção do próprio Barbosa Rodrigues, que, para esse fim ali se demorou nove meses. Trata-se de trabalho gráfico de primeira ordem, tanto pela reprodução colorida das estampas, como pelo texto e encadernação.

Surface-Bound Selectin-Ligand Binding Is Regulated By Carrier Diffusion

Two-dimensional (2D) kinetics of receptor-ligand interactions governs cell adhesion in many biological processes. While the dissociation kinetics of receptor-ligand bond is extensively investigated, the association kinetics has much less been quantified. Recently receptor-ligand interactions between two surfaces were investigated using a thermal fluctuation assay upon biomembrane force probe technique (Chen et al. in Biophys J 94:694-701, 2008). The regulating factors on association kinetics, however, are not well characterized. Here we developed an alternative thermal fluctuation assay using optical trap technique, which enables to visualize consecutive binding-unbinding transition and to quantify the impact of microbead diffusion on receptor-ligand binding. Three selectin constructs (sLs, sPs, and PLE) and their ligand P-selectin glycoprotein ligand 1 were used to conduct the measurements. It was indicated that bond formation was reduced by enhancing the diffusivity of selectin-coupled carrier, suggesting that carrier diffusion is crucial to determine receptor-ligand binding. It was also found that 2D forward rate predicted upon first-order kinetics was in the order of sPs > sLs > PLE and bond formation was history-dependent. These results further the understandings in regulating association kinetics of surface-bound receptor-ligand interactions.

Bifurcation in a reaction diffusion system

The bifurcation and nonlinear stability properties of the Meinhardt-Gierer model for biochemical pattern formation are studied. Analyses are carried out in parameter ranges where the linearized system about a trivial solution loses stability through one to three eigenfunctions, yielding both time independent and periodic final states. Solution branches are obtained that exhibit secondary bifurcation and imperfection sensitivity and that appear, disappear, or detach themselves from other branches.

Diffusion in glassy polymers

Fluid diffusion in glassy polymers proceeds in ways that are not explained by the standard diffusion model. Although the reasons for the anomalous effects are not known, much of the observed behavior is attributed to the long times that polymers below their glass transition temperature take to adjust to changes in their condition. The slow internal relaxations of the polymer chains ensure that the material properties are history-dependent, and also allow both local inhomogeneities and differential swelling to occur. Two models are developed in this thesis with the intent of accounting for these effects in the diffusion process.

In Part I, a model is developed to account for both the history dependence of the glassy polymer, and the dual sorption which occurs when gas molecules are immobilized by the local heterogeneities. A preliminary study of a special case of this model is conducted, showing the existence of travelling wave solutions and using perturbation techniques to investigate the effect of generalized diffusion mechanisms on their form. An integral averaging method is used to estimate the penetrant front position.

In Part II, a model is developed for particle diffusion along with displacements in isotropic viscoelastic materials. The nonlinear dependence of the materials on the fluid concentration is taken into account, while pure displacements are assumed to remain in the range of linear viscoelasticity. A fairly general model is obtained for three-dimensional irrotational movements, with the development of the model being based on the assumptions of irreversible thermodynamics. With the help of some dimensional analysis, this model is simplified to a version which is proposed to be studied for Case II behavior.

Studies in nuclear reactor dynamics : I. The accuracy of point kinetics. II. The effect of delayed neutrons on the spectrum of the group-diffusion operator

This thesis is a theoretical work on the space-time dynamic behavior of a nuclear reactor without feedback. Diffusion theory with G-energy groups is used.

In the first part the accuracy of the point kinetics (lumped-parameter description) model is examined. The fundamental approximation of this model is the splitting of the neutron density into a product of a known function of space and an unknown function of time; then the properties of the system can be averaged in space through the use of appropriate weighting functions; as a result a set of ordinary differential equations is obtained for the description of time behavior. It is clear that changes of the shape of the neutron-density distribution due to space-dependent perturbations are neglected. This results to an error in the eigenvalues and it is to this error that bounds are derived. This is done by using the method of weighted residuals to reduce the original eigenvalue problem to that of a real asymmetric matrix. Then Gershgorin-type theorems .are used to find discs in the complex plane in which the eigenvalues are contained. The radii of the discs depend on the perturbation in a simple manner.

In the second part the effect of delayed neutrons on the eigenvalues of the group-diffusion operator is examined. The delayed neutrons cause a shifting of the prompt-neutron eigenvalue s and the appearance of the delayed eigenvalues. Using a simple perturbation method this shifting is calculated and the delayed eigenvalues are predicted with good accuracy.
