1. A Biomechanical Analysis of the Interlock Suture and a Modified Kessler-Loop Lock Flexor Tendon Suture
OBJECTIVE: In this work, we attempted to develop a modified single-knot Kessler-loop lock suture technique and compare the biomechanical properties associated with this single-knot suture technique with those associated with the conventional modified Kessler and interlock suture techniques. METHODS: In this experiment, a total of 18 porcine flexor digitoru

2. Effect of CFRP and TRM Strengthening of RC Slabs on Punching Shear Strength
Abstract The paper presents experiments involving punching of RC slabs strengthened using externally bonded carbon fiber reinforced polymer (CFRP) sheet and textile reinforced mortar (TRM). Twelve RC slab specimens of two concrete grades (39.9 and 63.2 MPa) and employing two strengthening schemes (CFRP and TRM) were tested. Specimens were supported on two op

3. Production of porous ceramic materialusing different sources of alumina and calcia
ABSTRACTNumerous papers and publications report the use of microporous calcium hexaluminate (CaO.6Al2O3; CA6) as a key raw material for high temperature insulating materials. This material has unique properties with respect to chemical purity and mineral composition. Another important property of CA6 is its structure, which consists of platelet-shaped crysta

4. Material and geometric nonlinear analysis of reinforced concrete frame structures considering the influence of shear strength complementary mechanisms
A mechanical model for the analysis of reinforced concrete frame structures based on the Finite Element Method (FEM) is proposed in this paper. The nonlinear behavior of the steel and concrete is modeled by plasticity and damage models, respectively. In addition, geometric nonlinearity is considered by an updated lagrangian description, which allows writing

5. Development of mechanical, reliability and optimization models for application in reinforced concrete structures / Desenvolvimento de modelos mecânicos, de confiabilidade e de otimização para aplicação em estruturas de concreto armado
This work presents some developments in the mechanical modeling of reinforced concrete bar structures, as well in the coupling of reliability and RBDO optimization models, with the purpose of obtaining optimal dimensions considering the safety requirements specified in design. As for the mechanical modeling via Finite Element Method (FEM), in addition to geo

6. Experimental Study of Concrete Pavement: Influence of Position of Bar Transfer and Type of Concrete / Estudo Experimental de Pavimentos de Concreto: Influência da Posição da Barra de Transferência e do Tipo de Concreto
This work presents an experimental study of the behavior of transverse joints in unreinforced concrete slabs under elastic support. Due to the tensions caused by loads and volumetric variations in the slab, transverse joints when badly executed can cause a efficiency reduction in the shear transfer, thus reducing the useful life of the concrete pavement. To

7. Estudo do Efeito de Diferentes Granulometrias no Comportamento MecÃnico de Misturas AsfÃlticas Densas DescontÃnuas Tipo Stone Matrix Asphalt (SMA) / STUDY OF THE EFFECTS OF DIFFERENT GRADATIONS ON THE MECHANICAL BEHAVIOR OF DENSE GAP GRADED STONE MATRIX ASPHALT (SMA) MIXTURES
No meio rodoviÃrio brasileiro, que detÃm 96,2% da matriz de transporte de passageiros e 61,8% da matriz de cargas, Ã flagrante a deterioraÃÃo dos revestimentos asfÃlticos provocada pelo crescente aumento do volume e do peso das cargas transportadas. Tal configuraÃÃo contribui sobremaneira para o surgimento de defeitos, destacando-se as deformaÃÃes

8. Estudo comparativo de respostas estruturais antes da cura do concreto de formas metálicas incorporadas às lajes
Composite slabs are those in which cold formed steel sheets, fitted in each other at the edges, are used as shuttering, capable of supporting the wet concrete and construction loads, and as a positive reinforcement for the slab after concrete has hardened. There are some means of providing interlocking between the profiled steel sheet and the concrete that r

9. Avaliação experimental do comportamento estrutural de paredes não armadas, submetidas à compressão axial, construídas com tijolito
Unfortunately, researches involving the use of blocks set up without mortar and interlock have not been common. Tijolito is a soil-cement block, which can be used as a masonry component without the use of mortar in the horizontal joints. The wall stabilization is managed after the filling of the holes disposed in a way to fulfill this purpose, with fluid mor

10. Determination of the stereostructure of the product of Tn3 resolvase by a general method.
A method has been developed for determination of the absolute structure of DNA catenanes. The catenated DNA is partially denatured before being thickened with a coating of RecA protein and spread for electron microscopy. This treatment allows visualization of the orientation of each ring as well as identification of the overlying and underlying DNAs at cross

11. Facile Method for Monitoring Inhibition of Anaerobic Spore Outgrowth
A device is presented for the laboratory monitoring of spore outgrowth under controlled temperature and anaerobic conditions. Alterations in pH, redox potential, headspace composition, and optical density are followed as the activated spores grow out into vegetative cells. An interlock system allows the addition of test solutions or the removal of medium und

12. Structure of a bacterial enzyme regulated by phosphorylation, isocitrate dehydrogenase.
The structure of isocitrate dehydrogenase [threo-DS-isocitrate: NADP+ oxidoreductase (decarboxylating), EC 1.1.1.42] from Escherichia coli has been solved and refined at 2.5 A resolution and is topologically different from that of any other dehydrogenase. This enzyme, a dimer of identical 416-residue subunits, is inactivated by phosphorylation at Ser-113, wh
