Caragana microphylla is a sand-fixing leguminous shrub with strong resistance to OAK drought, cold, and low soil fertility.As a result, it plays an essential role in combating desertification in northern China, but little is known about its nutrient budget.Nutrient resorption is a key process in plant nutrient conservation and has marked ecological
The use of a volcanic material as filler in self-compacting concrete production for lower strength applications
This study evaluates the use of large amounts of fine powders (fillers) derived from a Colombian volcanic material into the production of self-compacting concrete (SCC) for lower strength applications.The effects on SCC properties were studied with the incorporation of up to 50% of volcanic material of Wine Bottle Holder Tolima (MVT) as a partial s
Cross-domain access control policy mapping mechanism for balancing interoperability and autonomy
Cross-domain access control can improves interoperability but reduces intra-domain autonomy.To balance inter-domain interoperability power center and intra-domain autonomy,a cross-domain access control policy mapping to the problem of multi-objective integer optimization programming was formulated.Both the maximization of inter-domain interoperabil
Fractional order model using Caputo fractional derivative to analyse the effects of social media on mental health during Covid-19
During the COVID-19 outbreak, a large population was exposed to social media.Since it was a new virus and no specific information was available about its dynamics, therefore people were dependent on social media to gather more and OAK more information.Social media has its pros and cons, which have an impact on the life of human beings which was mor
