The manufacture of highly drug-loaded fine globular granules eventually applied for orally disintegrating tablets has been investigated using a unique multi-functional rotor processor with acetaminophen, which was used as a model drug substance. Experimental design and statistical analysis were used to evaluate potential relationships between three key operating parameters (i.e., the binder flo...

Nitrogen removal is needed in microbial fuel cells (MFCs) for the treatment of most waste streams. Current designs couple biological denitrification with side-stream or combined nitrification sustained by upstream or direct aeration, which negates some of the energy-saving benefits of MFC technology. To achieve simultaneous nitrification and denitrification, without extra energy input for aerat...

Asphalt pavements undergo long-term aging due to oxidation of the asphalt binder. As a pavement oxidizes, it stiffens and eventually cracks. The use of an antioxidant in an asphalt binder could retard aging, thus increasing the pavement’s service life. Lignin is a known antioxidant and is highly available from timber and many agricultural products. A wet-mill ethanol process produces several co...

BACKGROUND: Clostridium septicum has played a significant role as a causative agent of many acute fetal diseases in man and animals. Alpha- toxin is the main factor in the pathogenesis of C. septicum with hemolytic, necrotic and lethal activities. OBJECTIVES: The study was designed to evaluate alpha-toxin purification and antibody production rate against a local strain of C. septicum NH2 which ...

Self-consolidating concrete (SCC) mixtures designated for precast, prestressed applications should be highly workable to flow easily through restricted spacing and completely encapsulate reinforcements without any mechanical vibration. Key workability characteristics of SCC can be described in terms of filling ability, passing ability, and resistance to segregation. These properties are typical...

introduction: widespread medical usage of botulinum toxins has increased the need for the precise analysis of its biological activity. the aim of this study was production and crystallization of the botulinum type a toxins. methods: in this study, clostridium botulinum was grown and inoculated into the tripticase soya broth culture media, under anaerobic condition and toxin production was monit...

SIEM (Speckle Interferometry with Electron Microscopy) is a micro/nano experimental mechanics technique that is able to perform the full field displacement mapping over a region of only several microns in size. In this study we tested specimens made of a pure binder material, a polymer, and binder material mixed with 6 micron aluminum particles under uniaxial tension. The binder material with m...
