In this study, secondary sludge (SS) from a kraft paper mill was used as a source of biomass to recover protein and investigate its potential use as a wood adhesive. The process of protein recovery involved disruption of the floc structure in alkaline medium to disintegrate and release intercellular contents into the aqueous phase followed by separation of soluble protein. Finally, the soluble ...

Targeted disruption of the surfactant protein (SP) D (SP-D) gene caused a marked pulmonary lipoidosis characterized by increased alveolar lung phospholipids, demonstrating a previously unexpected role for SP-D in surfactant homeostasis. In the present study, we tested whether the local production of SP-D in the lung influenced surfactant content in SP-D-deficient [SP-D(-/-)] and SP-D wild-type ...

The lung collectin surfactant protein D (SP-D) is an important component of the innate immune response but is also believed to play a role in other regulatory aspects of immune and inflammatory responses within the lung. The role of SP-D in the development of allergen-induced airway inflammation and hyperresponsiveness (AHR) is not well defined. SP-D levels progressively increased up to 48 hour...

The static random-access memory (SRAM) cells used in the high radiation environment of aerospace have become highly vulnerable to single-event effects (SEE). Therefore, a 12T SRAM-hardened circuit (RHB-12T cell) for soft error recovery is proposed using hardening design (RHBD) concept. To verify performance RHB-12T, cell simulated by 28 nm CMOS process and compared with other hardened (Quatro-1...

Logical frameworks have enjoyed wide adoption as meta-languages for describing deductive systems. While the techniques for representing object languages in logical frameworks are relatively well understood, languages and techniques for metaprogramming with them are much less so. This paper presents work in progress on a programming language called Rogue-Sigma-Pi (RSP), in which general programs...

The codesign of embedded real-time signal processing systems is complex. The use of commercial-off-the-shelf (COTS) multiprocessor (MP) hardware and software can reduce codesign complexity. Further complexity reduction can be obtained with emerging rapid system prototyping (RSP) frameworks, which can generate deployable code by leveraging vendor communication and computation libraries. However,...

We investigate graphs and hypergraphs that have (relaxed) product structures. In the class of graphs, we discuss in detail RSP-relations, a relaxation of relations fulfilling the square property and therefore of the product relation σ, that identifies the copies of the prime factors of a graph w.r.t. the Cartesian product. For K2,3-free graphs finest RSP-relations can be computed in polynomial-...

Segregation Distorter (SD) is an autosomal meiotic drive gene complex found worldwide in natural populations of Drosophila melanogaster. During spermatogenesis, SD induces dysfunction of SD(+) spermatids so that SD/SD(+) males sire almost exclusively SD-bearing progeny rather than the expected 1:1 Mendelian ratio. SD is thus evolutionarily "selfish," enhancing its own transmission at the expens...

Ideally, both ecosystem service and human development policies should improve human well-being through the conservation of ecosystems that provide valuable services. However, program costs and benefits to multiple stakeholders, and how they change through time, are rarely carefully analyzed. We examine one of China's new ecosystem service protection and human development policies: the Relocatio...

The Regulatory Studies Program (RSP) of the Mercatus Center at George Mason University is dedicated to advancing knowledge of the impact of regulation on society. As part of its mission, RSP conducts careful and independent analyses employing contemporary economic scholarship to assess rulemaking proposals from the perspective of the public interest. Thus, this comment on the Food and Drug Admi...
