This study specifically provides insights into the impact of idiosyncratic and covariate poverty shocks on poverty and inequality across various refugee and host community settlements in Uganda. The data shows that in Bidi Bidi Settlement, poverty decreased by 1.7 units while inequality increased by … …American Journal of Economics and Business Administration, Vol. 16, Issue 1 · 16 Aug 2024 · 8,186 accessesView PDFCite
Research ArticleOpen accessIn the abstractExpression and Induction Optimization of Mucor Circinelloides Lipase in Escherichia ColiYueping Yang, Yao Zhang et al.Microbial lipases serve as versatile biocatalysts for modifying lipid substrates, enabling diverse biotechnological applications spanning food technology, renewable energy production, and pharmaceutical sectors. Genomic analysis of Mucor circinelloides WJ11 revealed multiple lipase-encoding genes, with WJ_23 successfully cloned and heterologously expressed in Escherichia coli. Since the lipase expression was mainly concentrated in the cell pellets, appropriate induction strategies had been investigated … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 13 Jun 2025 · 5,982 accessesView PDFCite

Research ArticleOpen accessIn the abstractRegeneration of Lyes for Cleaning-In-Place (CIP) Processes in Dairies: Comparison of Recycled Potash and Soda Solutions Cleaning PropertiesMarie Furic, Anne Elain, Walid Blel, Olivier SireThe regeneration of lyes for their integration in the dairy CIP was investigated applying an original process combining adsorption/coagulation and flocculation operations. Solutions of potassium hydroxide (KOH) and caustic soda (NaOH) soiled with 1% (v/v) of whole milk were submitted up to twenty successive regeneration cycles. The multiple recycling of the regenerated solutions was found to modify their physicochemical characteristics … …American Journal of Applied Sciences, Vol. 12, Issue 5 · 6 Jul 2015 · 6,624 accessesView PDFCite
EditorialOpen accessIn the abstractON THE CHALLENGES OF THE USE AND INTEGRATION OF RENEWABLE ENERGY SOURCESMariano MartínOverview: Although renewable energy sources are plentiful, their availability is highly volatile in time and distributed across regions while and the processes that transform them into useful power or chemicals are underdeveloped. In this work we discuss on the scope for the use and integration of renewable energy sources and the future development of the alternatives. Energy, the sources and … …Energy Research Journal, Vol. 5, Issue 1 · 11 Sep 2014 · 7,540 accessesView PDFCite
