13. Theoretical and experimental analysis of space trusses / Análise teórica e experimental de treliças espaciais
This paper presents a study of the behavior of tubular circular section space trusses with the main emphasis placed on the performance of the various truss typologies used in Brazil. Nine space trusses with plan dimensions of 7.5m x 15.0m and one with plan dimensions of 7.5mx7.5m and height of 1.5m were tested. The joint type was varied with the objective to

14. STRUCTURAL BEHAVIOR OF TUBULAR SPATIAL TRUSSES / COMPORTAMIENTO DE EXTRUCTURAS ESPACIALES TUBULARES PADRONIZADAS / COMPORTAMENTO DE ESTRUTURAS ESPACIAIS TUBULARES PADRONIZADAS
This work presents an investigation of the structural behaviour of tubular space trusses composed of continuous end flattened members stacked above each other and joined together by a single bolt. One of the main motivations for this work comes from the fact that this structural solution is very commonly used in Brazil. The main reasons for that are the econ

15. Tubular precipitation and redox gradients on a bubbling template
Tubular structures created by precipitation abound in nature, from chimneys at hydrothermal vents to soda straws in caves. Their formation is controlled by chemical gradients within which precipitation occurs, defining a surface that templates the growing structure. We report a self-organized periodic templating mechanism producing tubular structures electro

16. The rat gene homologous to the human gene 9–27 is involved in the development of the mammary gland
We have developed a model system for studying differentiation in the mammary gland, by using two clonal cultures deriving from a rat breast adenocarcinoma. They differ in the ability to form domes, structures the significance of which is unknown. By using the subtractive cDNA library approach, we isolated a cDNA that is highly expressed in the dome-forming c

17. Biogenesis of Nanotubular Network in Toxoplasma Parasitophorous Vacuole Induced by Parasite Proteins
The intracellular parasite Toxoplasma gondii develops within a nonfusogenic vacuole containing a network of elongated nanotubules that form connections with the vacuolar membrane. Parasite secretory proteins discharged from dense granules (known as GRA proteins) decorate this intravacuolar network after invasion. Herein, we show using specific gene knockout
