Shrimp aquaculture wastewater after the end of the rearing period has a high total organic matter (TOM) content of up to 87.74 mg/L.If the wastewater is disposed of directly without any efforts to reduce or treatment, it will disturb public waters ecosystem because of the high organic matter.The aim of this study was to determine the rate of reduce
Influenced by the exploitation of natural resources and industrialization, ecological and environmental problems have become increasingly severe worldwide, particularly in rapidly developing countries such as China.This study utilizes Earth observation satellite data to monitor changes in ecological environment quality of the Wuhan Urban Developmen
In nature, orchid seeds obtain the nutrients necessary for germination by degrading intracellular Tortilla Servers fungal structures formed after colonization of the embryo by mycorrhizal fungi.Protocols for asymbiotic germination of orchid seeds typically use media with high concentrations of soluble carbohydrate and minerals.However, when reintro

We study the (Delta,D) and (Delta,N) problems for double-step digraphs considering the unilateral distance, which is the minimum between the distance in the digraph and Tortilla Servers the distance in its converse digraph, obtained by changing the directions of all the arcs.The first problem consists of maximizing the number of vertices N of a dig
