We systematically study several classical-quantum correspondence properties of the dissipative modifiedkicked rotator, a paradigmatic ratchet model. We explore the behavior of the asymptotic currents for finite effvalues...

Resumo O presente artigo busca avaliar a relevante colaboração da mão de obra e da cultura africana na construção de terra na arquitetura paulista, entre os séculos XVIII e XIX. A proposta ganha uma maior relevânc...

Apresenta uma proposta de periodização histórica do comentário esportivo no rádio de Porto Alegre, baseando-se em parâmetros para este tipo de estudo propostos por Agnes Heller (1997). Considera para tanto, como po...

This paper addresses trajectory tracking problem in mobile robots considering additive uncertainties. The controller design method is based on linear algebra theory. Numerical estimation techniques are used to estimate t...

We aim to determine the average efficiency levels of the Argentine Labor Courts and their individual behavior with respect to the average. We also seek to establish the determinants of the relative efficiency levels of t...

Diaphragmatic myoblasts (DM) are stem cells of the diaphragm, a muscle displaying high resistance to stress and exhaustion. We hypothesized that DM modified to overexpress connexin-43 (cx43), seeded on aligned poly (l-la...

The paper explores the theoretical and conceptual aspects of urban life quality (ULQ) synthesized in a model that includes the physical support of the cities, in our case of intermediate scales. This model considers the ...

Single photoionization cross sections for two different ground state orbitals of the molecule CH4 are presented. An angular averaged molecular model potential is used to represent the interaction of the ionized electrons...

Conventional approaches for the detection of antibody dependent cell-mediated cytotoxicity (ADCC) activity rely on quantification of the release of traceable compounds from target cells or flow cytometry analysis of popu...

Para avaliar o efeito de níveis de lisina digestível sobre o desempenho e as características de carcaça de suínos machos castrados dos 60 aos 100 dias de idade, foram utilizados 300 animais com peso médio de 25±0,...

Foi conduzido um experimento utilizando 128 leitões com peso inicial de 4,32 ± 0,55 kg, desmamados aos 14 dias de idade, distribuídos em delineamento em blocos, composto de quatro tratamentos, oito repetições ...

Abstract Objective To analyze marital outcomes, divorce or separation, and its association with demographic, socioeconomic, and clinicopathological factors among breast cancer (BC) survivors after 2-years of diagnosis....

Among the factors that influence the diversity of ectoparasites on bat hosts are the kind of roost and the host's social behavior. Other factors such as sex, reproductive condition and host size may influence the distrib...

Este artigo propõe-se a analisar as matrizes teóricas do sistema de voucher educacional, o qual consiste no subsídio oferecido pelo Estado às famílias, para que elas paguem a escola em que desejam que seus filhos es...

Lethal effects of active ingredients and formulations of widely used soybean pesticides were assessed with the Hydra attenuata toxicity test. Studied pesticides were insecticides chlorpyrifos and cypermethrin, and herbic...

In 2012, a severe drought struck the southeastern of Brazil compromising the Paraná River Basin reservoirs. Here, we described how this climatic event promoted a massive mortality of the giant freshwater mussel Anodonti...

Objectives: To evaluate motivations to perform an elective single embryo transfer (e-SET). Methods: Cross-sectional surveys to reproductive medicine specialists and to infertile patients undergoing assisted reproductive ...

Mobilization of iron (Fe) chelated by humic acids (HA) of low (HA10,000) and high molecular weight (HA100,000) fractions and its uptake by plants were investigated in growth experiments with sunflower seedlings. The iron...

Context. The ESO public survey VISTA variables in the Vía Láctea (VVV) started in 2010. VVV targets 562 sq. deg in the Galactic bulge and an adjacent plane region and is expected to run for about five years. Aims. We ...

From 2008 to 2011, several planned modifications were implemented at the RA-6 reactor in Argentina, leading to significant benefits for future BNCT treatments. New capabilities have been implemented in NCTPlan treatment ...

The main objective of this research work is to develop a new low-cost isolated three-level ac-dc power converter topology with a reduced number of switches. Existing three-level converter topologies change ac power to dc...

Compounds from the metasternal and Brindley´s glands of the blood-sucking bug, Triatoma infestans, were identified by solid phase microextraction (SPME) and gas chromatography-mass spectrometry.Volatile compounds releas...
