We have carried out continuous and step uniaxial extension experiments on monodisperse and bidisperse styrene-butadiene random copolymers (SBR) to demonstrate that their nonlinear rheological behavior can be understood in terms of yielding through disintegration of the chain entanglement network and rubber-like rupture via non-Gaussian chain stretching leading to scission. In continuous extensi...

1 Abstract This paper describes some recent work to extend the capability of the Epsilon™ Radar Cross Section (RCS) prediction code to model the scattering from diffusive and grating structures. The paper provides an overview of basic approaches to the calculation of multiple scattering interactions and then describes the Diffuse ray and Huygens algorithm extensions. A basic Shooting Bouncing R...

In this work, the influence of bisphenol A (BPA) on biological wastewater treatment was studied. For it, two sequencing batch reactors (SBRs) were operated for three months. Both SBRs fed with synthetic (SW), adding 1 mg·L−1 BPA into feed reactor SBR-BPA, while other one without as a control (SBR–B). addition, experiments performed adapted and non-adapted activated sludge, simulating reaction s...

This paper presents an undergraduate student research project which involved a new power diode called the Super Barrier Rectifier (SBR) diode. Several projects incorporating SBR diodes in dc-dc converters performed by undergraduate students will be described. Challenges in conducting these projects along with results will also be discussed.

A decision support system for wastewater treatment plant (WASDA) was developed to make appropriate decisions on plant design and process selection. WASDA mainly focused on municipal and industrial applications to produce conceptual and process design for primary, secondary and advanced treatments. It consists of multiple modules such as equalization tank, coagulation, neutralization, convention...

MPEG Spectral Band Replication (SBR) is the newest compression technology available as part of the MPEG standards. It is combined with MPEG Advanced Audio Coding (AAC) and improves coding efficiency by more than 30%. The resulting scheme is called High-Efficiency AAC (HE AAC). This presentation explains MPEG SBR and its integration into the existing MPEG-4 bitstream format. The SBR technology i...

BACKGROUND & AIMS Intestinal adaptation is a compensatory response to the massive loss of small intestine after surgical resection. We investigated the role of intestinal epithelial cell-specific mammalian target of rapamycin complex 1 (i-mTORC1) in intestinal adaptation after massive small bowel resection (SBR). METHODS We performed 50% proximal SBR on mice to study adaptation. To manipulate...

Several anatomical anterior cruciate ligament (ACL) reconstruction techniques have been proposed to restore normal joint kinematics. However, the relative superiorities of these techniques with one another and traditional single-bundle reconstructions are unclear. Kinematic responses of five previously reported reconstruction techniques (single-bundle reconstruction using a bone-patellar tendon...

A character is a result of the cooperative action of all genes, although some genes alone, and in case of “factor interaction,” more than one gene, are chiefly concerned in the development of a particular character. Interacting genes, as well as modifiers, may be specific in their effect, since they can act only in the presence of a particular genetical environment (BRIDGES 1919), and non-speci...
