Objectives. The objective was to determine the fracture and cyclic fatigue properties of composite–dentin beams bonded with a self-etching adhesive in four-point bend. Methods. Beams of rectangular cross-section were shaped to a size of ∼0.87mm×0.87mm×10mm and placed in a four-point bending apparatus, with the loading points 1.8 and 7.2mm apart, with the interface centered between the inner rol...

In the production of industrial enzymes, filamentous fungi are attractive as cell factories because they can secrete large amounts of protein into the medium. Many important industrial enzymes such as amylases, lipases and cellulase are produced by fermentation of filamentous fungi. Aspergillus oryzae is well-known filamentous producer of alpha amylase and has GRAS status. In the present study ...

An experiment was conducted at the Indian Agricultural Research Institute, New Delhi (2017-18) to report identification of halophilic poly-ß-hydroxybutyrate (PHB) producing bacteria and optimization process parameters for maximum PHB recovery. The phylogenetic analysis classified isolates into bacterial phylum α, γ-Proteobacteria, Firmicutes. Halomonas sp. KB7 Stenotrophomonas maltophila B11 pr...

Latest estimates indicate that nutritional deficiencies account for 3 million child deaths each year in less-developed countries. Targeted nutritional interventions could therefore save millions of lives. However, such interventions require careful optimization to maximize benefit and avoid harm. Progress toward designing effective life-saving interventions is currently hampered by some serious...

We show how a particular spatial structure with a buffer globally stabilizes the chemostat dynamics with non-monotonic response function, while this is not possible with single, serial or parallel chemostats of the same total volume and input flow. We give a characterization of the set of such configurations that satisfy this property, as well as the configuration that ensures the best nutrient...
