1. Geometrically nonlinear analysis of thin-walled laminated composite beams
Abstract The use of thin-walled composite beams in Engineering has attracted great interest in recent years. Composite beams and other structural elements tend to have thin walls due to the high strength of the material. Other important aspect is that, even without reaching large strains and without overcoming the elastic limit of the material, such as beams

2. Estudo de cálice de fundação com ênfase nos esforços nas paredes transversais do colarinho / Study of the socket base foundation with emphasis on the efforts of transverse walls
Este trabalho apresenta uma análise da ligação pilar-fundação por meio de cálice em estruturas de concreto pré-moldado, focando os esforços nas paredes transversais do colarinho. No programa experimental foram ensaiados dois protótipos submetidos à flexão com grande excentricidade: um com interface pilar-colarinho lisa e o outro com interface rugo

3. Morphoanatomical characterization of Gentianaceaes species from cerrado and campo rupestre in Minas Gerais / Caracterização morfoanatômica de espécies de Gentianaceae ocorrentes em áreas de cerrado e de campo rupestre em Minas Gerais
The family Gentianaceae presents between 1600 and 1700 species predominantly herbaceous. In Brazil, 25 genera of this family occur mainly in the Cerrado and campos rupestres. The species are included into 6 tribes and 86 genera. The tribe Chironieae presents around 159 species distributed into 23 genera, such as Schultesia and Deianira. The tribe Helieae exh

4. MAGNETOIMPEDÂNCIA COMO FERRAMENTA PARA A CARACTERIZAÇÃO MAGNÉTICA DE MICROFIOS AMORFOS / MAGNETOIMPEDANCE AS A TOOL TO INVESTIGATE THE MAGNETIC PROPERTIES OF MICROWIRES
The possibility of exploring the magnetic properties of amorphous microwires in technological applications has attracted the attention of the scientific community in the last years. Beyond, the magnetoimpedance effect has been established as a powerful tool to study these properties. In this work we show a study of the magnetic properties of Joule heated gla

5. Impact control of structural vibrations excited by nonideal loads. / Controle por impacto de vibrações estruturais excitadas por carregamentos não-ideais.
We present mathematical models with few degrees of freedom for the study of nonlinear structural vibrations excited by a non ideal energy source, with impact damping, for two applications: a portal frame that supports an electric motor and a tower structure supporting an aeolian turbine. We consider that there is interaction between the energy supply and the

6. Análise não-linear de estruturas tridimensionais de edifícios de andares múltiplos com núcleos resistentes, considerando a rigidez transversal à flexão das lajes / Non linear analysis of three-dimensional structures of multistory buildings with core walls, considering the bending stiffness transverse of slabs
The main aim of this work is to apresent a study about analysis of three-dimentional structures of multistory buildings considering the interaction of displacements and stresses of the elements of the structures, with the influence of the transverse bending stiffness of slabs. The plate finite elements adopted in floor discretization, responsible for conside

7. Transverse Viscoelastic Extension in Nitella: II. Effects of Acid and Ions 1
The transverse viscoelastic extension of isolated Nitella cell walls is stimulated by acid pH and by Mg2+ and K+ ions. In the presence of 1 millimolar citrate-phosphate buffer the threshold pH in the transverse direction is 3.5, compared to 4.5 in the longitudinal direction. The relative amounts of extension stimulated by acid are comparable in the two direc

8. Suppression and acceleration of cell elongation by integration of xyloglucans in pea stem segments
Xyloglucan is a key polymer in the walls of growing plant cells. Using split pea stem segments and stem segments from which the epidermis had been peeled off, we demonstrate that the integration of xyloglucan mediated by the action of wall-bound xyloglucan endotransglycosylase suppressed cell elongation, whereas that of its fragment oligosaccharide accelerat

9. Cell Expansion Patterns and Directionality of Wall Mechanical Properties in Nitella.1
As a means of assessing the extent to which deformation of isolated walls relates to in vivo cell expansion, the directionality of wall mechanical properties was examined in Nitella. Measurements were made of plastic and elastic deformation and creep under both uniaxial and multiaxial stress conditions. Walls of different structural characteristics were obta

10. Osteolytic phaeohyphomycosis in a German shepherd dog caused by Phialemonium obovatum.
Phialemonium obovatum was found to be the cause of osteomyelitis in a German shepherd dog. Histologic examination of the biopsied material from the left tibia revealed septate, irregularly branched hyphae, swollen cells, and ovate-to-spherical cells divided by a transverse septum. The majority of the fungal elements were hyaline, but a few had lightly pigmen

11. Blood sinuses in the submucosa of the large airways of the sheep.
We have studied the airway vasculature in sheep using light and transmission electron microscopy, as well as arterial and venous (retrograde) injections of anatomical corrosion compound and latex. Vascular casts were viewed by scanning electron microscopy. There is a complex network of blood sinuses of large diameter (up to 500 microns) in the submucosa of t

12. Do Xylem Fibers Affect Vessel Cavitation Resistance?1
Possible mechanical and hydraulic costs to increased cavitation resistance were examined among six co-occurring species of chaparral shrubs in southern California. We measured cavitation resistance (xylem pressure at 50% loss of hydraulic conductivity), seasonal low pressure potential (Pmin), xylem conductive efficiency (specific conductivity), mechanical st
