Study on isolation methods of natural polysaccharides

Polysaccharides are a significant and varied class of biomolecules that are vital to human health. They are complex carbohydrates made up of monosaccharide units. This scientific article provides a comprehensive review of the sources, extraction methods, and biomedical properties of polysaccharides. Understanding the intricacies of polysaccharides is crucial for harnessing their potential in various biomedical applications, ranging from drug delivery systems to immunomodulation. Polysaccharides are abundant in nature and can be found in a range of sources, such as marine organisms, bacteria, and plants. The unique structural diversity and inherent bioactivity of polysaccharides make them attractive candidates for biomedical research. This article aims to elucidate the diverse sources of polysaccharides, methods of extraction, and their biomedical properties

Impact of foreign direct investment on income inequality: Evidence from selected Asian economies.

The United Nations lists 17 Sustainable Development Goals for Agenda 2030, one of which is SDG-10, which focuses on eradicating inequality and addressing critical regional and global challenges. The fight against income inequality is heavily dependent on foreign direct investment all over the world. In this connection, the present study aimed to investigate the individual and interactive impact of foreign direct investment, human capital, and economic growth on income inequality by employing the interactive model. Based on the panel data set covering ten counties spanning each region of Asia from 1990 to 2020. In light of the slope homogeneity, cross-sectional dependency tests, and Westerlund co-integration test, we discover that all of the variables are cointegrated over the long run. A cross-sectional IPS (CIPS) unit root test is employed to check stationarity. Additionally, the study used the Augmented Mean Group (AMG) approach to produce accurate results in estimation. The results confirm that FDI affects inequality negatively. However, the impact of FDI is more effective in the presence of human capital. It means that human capital deepens the effect of FDI on inequality; the country will be more effective in reducing inequality by having a higher level of human capital and consider it a more powerful tool to bring equality. To reduce inequality, it is suggested that a policy mix of FDI and HC could be made

Influence of Mineralized Water Sources on the Properties of Calcisol and Yield of Wheat (<i>Triticum aestivum</i> L.)

The use of conservation agriculture (SWC—soil and water conservation) technologies is now becoming more and more necessary. For the soils in arid ecosystems, the problem of irrigation deficiencies has always been relevant, and clean fresh water is always insufficient to irrigate these agricultural lands. This paper provides a brief historical overview of the use of mineralized water sources in agriculture and their impacts on soils and plants (Triticum aestivum L.). The experiment involving wheat cultivation in saline soils irrigated with mineralized water was set for 3 years. The main chemical and physical–chemical properties of the agro-transformed solonchaks and mineralized water sources were investigated. According to the contents of mobile forms of N, P, and K, the soils were poorly supplied; after a series of irrigation phases, they remained the same. There were signs of the growth of mobile phosphorus in the variants where mineralized water sources were applied. Our results showed that under conditions of irrigation with water sources with mineralization rates of up to 2.8–3.5 g/L, the wheat yield increased by 1.5 c/ha compared to the control. The use of mineralized water for irrigation purposes will reduce the use of clean river water
