1. Fastener Demands for Sheathing-Braced Cold-Formed Steel Stud Gravity Walls
Abstract We explore, in this paper, the demands and behavior on fasteners supplying sheathing-based bracing of gravity loaded cold-formed studs and wall assemblies. The studies are carried out by shell finite element (FE) models, which are compared to analytical solutions and previously completed laboratory tests conducted by the authors. The connection betw

2. Soil-Framed Structure Interaction Analysis - A New Interface Element
AbstractInterfacial behavior between soil and shallow foundation has been found so influential to combined soil-footing performance and redistribution of forces in the superstructure. This study introduces a new thin-layer interface element formulated within the context of finite element method to idealize interfacial behavior of soil-framed structure intera

3. Effect of relative humidity on creep-shrinkage behaviour of composite tall buildings
Relative humidity of environment affects creep and shrinkage behaviour of a concrete member of composite tall buildings. These buildings are more prone to redistribution of forces as adjacent steel columns and RCC shear walls have quite different characteristics. In this paper, study is carried out to evaluate the effect of relative humidity of environment f

4. The Jewish people in the city of São Paulo (Brazil): the migration from the districts of Bom Retiro to Morumbi. / A territorialização dos judeus na cidade de São Paulo-SP: a migração do Bom Retiro ao Morumbi
It is believed that almost all global human mobility is in the history of "mass" immigration, however, this immigration has fulfilled an important and transcendental role for the elaboration of concepts about the relation among: society - space / society - nature / space and time. The various migratory events in the history of Jewish people and in their incl

5. Alloying in GeSi:Si (001) epitaxial nanocrystals / Formação de ligas em nanocristais epitaxiais de GeSi:Si (001)
The structural and electronic properties of nanoscale materials strongly depend on the chemical composition, as well as their size and shape. A big variety of morphologies can be achieved by controlling the experimental conditions during the epitaxial growth of Ge on a Si(001) substrate. In particular, three-dimensional islands with well defined size and sha

6. LAND-USE DECISION MAKING, UNCERTAINTY AND EFFECTIVENESS OF LAND REFORM IN ACRE, BRAZILIAN AMAZON
From 1970 to 1999, almost 700,000 families were settled through land reform programs in Brazil. However, lot turnover contributed to re-concentration of land and to the limited success of these programs. This dissertation explores land-use decision-making in an aging land reform settlement in the Amazon. It focuses on how farmers respond to limited access to

7. Mudança em tempos de globalização: o capitalismo não é mais progressista?
Technical progress and economic development are promotions of capitalism, says a well known idea hereby contradicted. Recent changes under neoliberalism show that the more freedom of move to capital the less development of productive forces. There was no synchronicity and coherence fostering economic growth between changes at the micro level of techno-produc

8. Análise da redistribuição de esforços em vigas de concreto protendido com seções compostas. / Analysis of the force redistribution in prestressed concrete beams with composite sections.
No cálculo das perdas progressivas de protensão, decorrentes da retração e da fluência do concreto e da relaxação do aço de protensão, a norma NBR 6118 prescreve dois procedimentos simplificados, indicados para fase única de operação, ou seja, quando se consideram fases únicas de concretagem, de carregamento permanente e de protensão; e o méto

9. The Effect of Ultracentrifugation on Fine Structure and α-Amylase Production in Barley Aleurone Cells 1
Ultracentrifugation of barley aleurone cells results in the stratification of organelles thus allowing for a quantitation of those organelles. Gibberellic acid (GA3)-stimulated α-amylase production in stratified cells is reduced by centrifugation at gravitational forces greater than 40,000g. Forces below 30,000g do not affect GA3-stimulated α-amylase produ

10. Heinz bodies induce clustering of band 3, glycophorin, and ankyrin in sickle cell erythrocytes.
In earlier model studies we demonstrated that artificially denatured hemoglobin binds to and clusters the protein, band 3, in the plane of the erythrocyte membrane. To determine whether denatured hemoglobin also clusters band 3 in vivo, we have compared the locations of denatured hemoglobin aggregates (Heinz bodies) with band 3 in sickle cells using phase co

11. Quantitative studies of endothelial cell adhesion. Directional remodeling of focal adhesion sites in response to flow forces.
Focal adhesion sites were observed in cultured endothelial cells by tandem scanning confocal microscopy and digitized image analysis, techniques that provide real-time images of adhesion site area and topography in living cells. Image subtraction demonstrated that in the presence of unidirectional steady laminar flow (shear stress [tau] = 10 dyn/cm2) a subst

12. Traction Stresses and Translational Distortion of the Nucleus During Fibroblast Migration on a Physiologically Relevant ECM Mimic
Cellular traction forces, resulting in cell-substrate physical interactions, are generated by actin-myosin complexes and transmitted to the extracellular matrix through focal adhesions. These processes are highly dynamic under physiological conditions and modulate cell migration. To better understand the precise dynamics of cell migration, we measured the sp
