The paper proposes a comprehensive and operational definition of Sustainable Food Packaging (SFP). Sustainability is multifaceted concept, yet most SFP conversations decline it as mere material substitution issue. efforts regulators, packaging producers, food companies, consumers towards the design adoption products are likely to fail without common understanding multiple means by which contrib...

Severe feather pecking (SFP) is a behavioral disorder, for which there are multifactorial reasons. Various aspects of pullet and laying-hen husbandry—including housing conditions, management, feeding, genetics—must be considered, to prevent negative outcomes, such as severe plumage damage, skin injuries, high mortality rates due SFP. The aim this study was identify management factors in the occ...

Abstract This study aims to employ clam powder as an environmentally acceptable sorbent capture lead(II) from aquatic media. Mussel Brachidontes variabilis “ Mytilus arabicus ” shells collected the intertidal zone of Gulf Suez for producing shellfish (SFP). Before and after lead loading, SFP was characterized using X-ray fluorescence (XRF), Fourier transform infrared (FT-IR) spectra, transmissi...

BACKGROUND Phosphopantetheinyl transferases (PPTases) catalyze the posttranslational modification of carrier proteins by the covalent attachment of the 4'-phosphopantetheine (P-pant) moiety of coenzyme A to a conserved serine residue, a reaction absolutely required for the biosynthesis of natural products including fatty acids, polyketides, and nonribosomal peptides. PPTases have been classifie...

We give a new characterization of sober spaces in terms of their completely distributive lattice of saturated sets. This characterization is used to extend Abramsky's results about a domain logic for transition systems. The Lindenbaum algebra generated by the Abramsky nitary logic is a distributive lattice dual to an SFP-domain obtained as a solution of a recursive domain equation. We prove tha...
