Enhancement of astaxanthin production from food waste by Phaffia rhodozyma screened by flow cytometry and feed application potential.

Astaxanthin is widely used in food, aquaculture, cosmetics, and pharmaceuticals due to its strong antioxidant activity and coloring ability, but its production from Phaffia rhodozyma remains the main challenge due to the high fermentation cost and low content of carotenoid. In this study, the production of carotenoids from food waste (FW) by a P. rhodozyma mutant was investigated.

The specific glycerolipid composition is responsible for maintaining the membrane stability of Physcomitrella patens under dehydration stress.

Land colonization is a major event in plant evolution. Little is known about the evolutionary characteristics of lipids during this process. Here, we proved that Physcomitrella patens, a bryophyte that appeared in the early evolution of terrestrial plants, has short-term desiccation resistance.

Simulation study on the mining conditions of dissolution of low grade solid potash ore in Qarhan Salt Lake.

The output and grade of liquid potash minerals in Qarhan Salt Lake are decreasing year by year, which has become the main problem restricting the sustainable production of potassium fertilizer. The exploitation and utilization of low-grade solid potash ore, which is in the strata of the Qarhan Salt Lake, represents the fundamental framework for the sustainable development of Qarhan Salt Lake's potash fertilizer. PHREEQC is a simulation software for hydrogeochemistry.

Mitigating the impact of coronavirus disease 2019 on emergency stroke care: an original study and meta-analysis.

The coronavirus disease 2019 is still continuing and may affect stroke emergency care. We aim to investigate the impact of pandemic on stroke treatment in tertiary stroke centers in western China, and to quantitatively evaluate the worldwide influence with a meta-analysis. The original part was conducted in three tertiary stroke centers in Sichuan province.

DisEHPPC: Enabling Heterogeneous Privacy-Preserving Consensus-Based Scheme for Economic Dispatch in Smart Grids.

These days, the increasing incremental cost consensus-based algorithms are designed to tackle the economic dispatch (ED) problem in smart grids (SGs). However, one principal obstruction lies in privacy disclosure for generators and consumers in electricity activities between supply and demand sides, which may bring great losses to them. Hence, it is extraordinarily essential to design effective privacy-preserving approaches for ED problems.

Web malware spread modelling and optimal control strategies.

The popularity of the Web improves the growth of web threats. Formulating mathematical models for accurate prediction of malicious propagation over networks is of great importance. The aim of this paper is to understand the propagation mechanisms of web malware and the impact of human intervention on the spread of malicious hyperlinks.

[In situ immobilization of Pb and Cd in orchard soil using soil ameliorants].

In situ immobilization of Pb and Cd in soil of two gardens in Golden Orchard of Chongqing was studied using soil ameliorants, which included eight treatments: control, quicklime, superphosphate, organic manure, quicklime + superphosphate, quicklime + organic manure, superphosphate + organic manure, and quicklime + superphosphate + organic manure. The results showed that all ameliorant treatments could decrease soil acidity in both the loquat garden and peach garden except the superphosphate treatment. Compared with the control, the soil pH in the two gardens increased by 0.
