Effect of fluidised bed drying on ginsenoside content in hairy root cultures of Panax ginseng C.A. Meyer

open access: yesIndonesian Journal of Biotechnology, 2023
Korean Ginseng (Panax ginseng C.A. Meyer) is a high‐value herb with many pharmacological benefits due to its primary active compound, ginsenosides. The most ginsenosides are known to be thermolabile and susceptible to degradation at high‐temperature ...

Computational Modelling of Gas-Solid Hydrodynamics and Thermal Conduction in Gasification of Biomass in Fluidized- Bed Reactor

open access: yesChemical Engineering Transactions, 2017
A computational fluid dynamic model is developed to describe the fluid–particle interaction inside a fluidised bed reactor. The proposed gasifier reactor is 5 kW self-sustaining fluidised bed with 500 mm height and 127 mm diameter.The selected feedstock ...

Improving of drinking water quality by remineralisation

open access: yesActa Chimica Slovenica, 2015
The reason of low mineral content in source water is that it originates in the poor soluble mineral geological structures. There are more areas with very soft low-mineralized water in Slovakia.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Effect of hydrodynamic parameters on the oxidative desulphurisation of low rank coal

open access: yesInternational Journal of Coal Science & Technology, 2018
In this paper, the desulphurisation of high sulphur low-rank coal is proposed as a raw material for pulverised coal injection technology. Therefore, the influence of oxidant linear velocity and the size of the coal grain was investigated in a fluidised ...

Recovery of Cenospheres and Fine Fraction from Coal Fly Ash by a Novel Dry Separation Method

open access: yesEnergies, 2020
Aluminosilicate microspheres are a valuable fraction of coal fly ash with diverse applications due to their low density. Currently, there is no efficient and ecologically rational method of cenosphere recovery from fly ash.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Tailored Syngas Production from the Gasification of Biogenic Waste in the Presence of a CO2 Sorbent

open access: yesChemical Engineering Transactions, 2020
Syngas production via steam gasification is one of the thermochemical processes with the greatest potential for obtaining synthetic fuels from a solid fuel, especially indirect gasification in a dual fluidised bed system where the energy needed for ...

Start-up and performance of a downflow fluidised bed reactor for biological treatment of yellow wastewater and nutrient recovery

open access: yesWater Science and Technology, 2022
The treatment of yellow water (human urine) in a downflow fluidised bed reactor (DFFBR) was investigated to evaluate biological ureolysis and nutrient recovery. The reactor was operated at 30±4 °C in batch mode, and reaction time = 1 d.
