Side-stream products of edible oil refining as feedstocks in biodiesel production [PDF]
Reciklaža i Održivi Razvoj, 2016 Biodiesel, a diesel fuel alternative, is produced from vegetable oils and animal fats by the transesterification reaction of triacylglycerols and lower aliphatic alcohols.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Refining Approaches in the Platinum Group Metal Processing Value Chain—A Review
Metals, 2018 Mineable platinum group metal (PGM) deposits are rare and found in relatively few areas of the world. At the same time, the use of PGM is predicted to expand in green technology and energy applications, and PGMs are consequently currently listed as ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Anais do XIV Simpósio Brasileiro de Engenharia de Software (SBES 2000), 2000 The refinement calculus is a modern technique of formal program development. Its application, however, may lead to long and repetitive developments. In this paper we present a language to write refinement tactics, and present examples of useful tactics.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Enhancing the efficiency of propylene recovery from a polypropylene plant flare
Journal of Engineering and Applied ScienceThe growing demand for olefins driven by their widespread use in petrochemical industries, particularly in polypropylene production, has brought attention to inefficiencies in certain operational processes.

Fifth IEEE International Conference on Software Engineering and Formal Methods (SEFM 2007), 2007 Development by formal stepwise refinement offers a guarantee that an implementation satisfies a specification. But refinement is frequently defined in such a restrictive way as to disallow some useful development steps. Here we define feature refinement to overcome some limitations of refinement and show its usefulness by applying it to examples taken ...
