Food Chemistry International, EarlyView.Composite sourdough breads were developed from blends of unripe plantain, tiger nut, and fenugreek flours. Optimized formulations improved pasting stability and enhanced texture, producing softer more elastic crumbs. The enriched breads contained higher dietary fiber and bioactive compounds, and significantly reduced serum cholesterol markers ...

Effect of Additives on Rheological Properties and Fluid Loss of Oil Based Drilling Fluids
Annual Transactions of the Nordic Rheology SocietyOil-based drilling fluids are often used to drill geothermal or petroleum wells in hot locations. These fluids normally consist of dispersion of organophilic clays in water-in-oil emulsions. If loss of fluid to the formation is expected, fibres or other additives for fluid loss prevention are added.

Archaeometry, EarlyView., 2022 Abstract Organic residue analysis was conducted on various vessels from burials at Tel Yehud, Israel. The analyses led to new reliable evidence for the presence of opioid alkaloids and their decomposition products. This research revitalizes a decades‐old discussion on the presence and function of the opium trade across a cultural region of utmost ...
