This study presents an investigation of a new redundant system to prevent the potential progressive collapse of reinforced concrete buildings resulted from a column failure. It is proposed to transfer the residual loads upward above the failed column of reinforced concrete buildings by vertical cables connected to the…
Nickel-based magnetic activated carbon was synthesized from coconut shell activated carbon by electroless plating with palladium-free activation. The effect of plating solution volume on metallic ratio and adsorption capacity were evaluated. The effect of metallic ratio on specific area, pore volume, and magnetic prop…
We present the results of the taxonomic study of Surirella genus in eleven aquatic environments, including isolate water bodies and channels between the islands of the Delta do Jacui State Park. This park is located in the Guaiba hydrographic Basin, Rio Grande do Sul State. Five species and six taxonomic varieties are…
Abstract This article describes a low‐cost image acquisition and processing system, which measures several yarn production characteristics, namely, the fibers twist orientation, the folded yarn twist step, the folded yarn twist orientation, and the existence of single (nonfolded yarn) or multiple cables (folded yarn).…
The reaction of [n-Bu(2)SnO](n) with 1,5-naphthalenedisulfonic acid tetrahydrate in a 1:1 stoichiometry followed by reaction with 2,2'-bipyridine-N,N'-dioxide (BPDO-I) afforded a 1D-coordination polymer [n-Bu(2)Sn(BPDO-I)(1,5-C(10)H(6)(SO(3))(2))](n) (1) where the disulfonate ligand acts as a bridging ligand between t…

Abstract New dithienothiophene‐containing conjugated polymers, such as poly(2,6‐bis(2‐thiophenyl‐3‐dodecylthiophene‐2‐yl)dithieno[3,2‐b;2′,3′‐d]thiophene, 4 and poly(2,6‐bis (2‐thiophenyl‐4‐dodecylthiophene‐2‐yl)dithieno[3,2‐b;2′,3′‐d]thiophene, 8 have been successfully synthesized via Stille coupling reactions using…
An optically assisted charge-pumping (CP) technique is proposed for the characterization of interface traps in floating-body (FB) devices. Even without a body contact, majority carriers can be supplied into the FB by light illumination, which contributes to enabling the CP process. Under a strong inversion enabled by…
A novel ring structure is proposed for double negative NIMs at visible light spectrum with high FOM (e.g. about 11 at a wavelength of 583 nm) and low loss. Besides the effective medium theory, an equivalent circuit model is also given to explain physically why our novel structure can give double negative behavior with…

Exact optical analysis of transparent-conductive-oxide (TCO) thin films are necessary to optimize adequate materials for optical sensor and solar cell applications. A non-numerical theoretical concept has been used to extract approximation-free optical, structural and electrical data from ultraviolet/visible/near-infr…
A bioengenharia tecidual é um campo multidisciplinar que aplica os princípios das ciências biológicas e das engenharias para o desenvolvimento de substitutos de órgãos e tecidos que visem à sua regeneração, com consequente melhoria da estética e função. Desta forma, a bioengenharia tecidual encontra-se frente ao desaf…
This paper presents an experimental investigation to enhance damping properties of concrete by using polymeric admixtures. The imperfections of conventional concrete such as low tensile strength, low ductility, and low damping have to be modified and improved. Specifically, polypropylene fibers and styrene butadiene r…
Propagating brush discharges can release large amounts of energy. From the point of view of safety, this feature makes them among the most destructive electrical discharges. This paper provides a survey of recent work in the modeling of propagating brush discharges. Experimental data from various authors are compared…
The amount of gas that penetrates the barrier of a vacuum insulation panels is directly linked to the service life of that panel. Therefore, to model and predict vacuum insulation panel service life, it is necessary to model the diffusion through its barriers. Best barriers on the market today are composites of multip…
The fluid flows in hydrothermal growth vessels have significant effects on growth quality. This article presents a numerical investigation on the fluid flow and heat transfer in an industry hydrothermal autoclave. The focus is on the modeling of the seed crystals in the growth chamber, the raw lascas in the dissolving…
We consider the equilibrium conditions for nucleation at the liquid-vapor transition at fixed volume in contrast to the traditional fixed pressure treatment. Significant differences appear, particularly for the stability of the diphasic states, which strongly depends on the external conditions.
Reichlich komplex: Eine polysomatische Serie von komplexen Oxiden zur Immobilisierung von Actinoiden beruht auf dem Einbau von Pyrochlor-Nanoclustern (hellbraun) in modifizierte Muratait-ähnliche Gerüste (blau). Diese Oxid-Serie ist eine der anspruchsvollsten Familien komplexer, auf der Nanometerebene maßgeschneiderte…
The nonlinear oscillation can be described by FlynnEquation when considering the compressibility of inner gas of bubbles. Basedon the model the displacement/the time relation and phase-trajectory ofvibrating bubbles of different initial radii are simulated numerically,which shows that the movements of bubbles depend s…
In this study, an aluminum–nickel–lanthanum (Al–Ni–La) alloy is introduced, for the first time, to hydrogenated amorphous silicon thin film transistor (a-Si:H TFT) for gate metallization technology. Ni atoms in Al–Ni–La can effectively improve contact characteristic with ITO film, while La can increase the uniformity…
