Purpose: Today, the efficient management of supply chains plays a fundamental role in the market and economy.The supply chain is a network of facilities working together to make and move products Pipe Parts from upstream to downstream to provide customers with highly qualified products and services.Nowadays, construction has become a growing and hu
In this article the influence of abiotic factors on agrophytocoenoses is considered, these are: moisture supply, rising air temperature, increasing carbon dioxide concentration, and the probability of environmental risks in particular.The degree of ecological risk has been established.Environmental risks due to the influence of climate change on ag
Plant-ants live in a mutualistic association with host plants known as "myrmecophytes" that provide them with a nesting place and sometimes with extra-floral nectar (EFN) and/or Foot Leveler food bodies (FBs); the ants can also attend sap-sucking Hemiptera for their honeydew.In return, plant-ants, like most other arboreal ants, protect their host p
[Objective] Due to the constraints of surface implementation conditions and underground space limitations, the implementation of underground utility tunnel in central urban area has poor feasibility.To address this issue, the concept of integrating the utility tunnel with metro system is proposed to achieve synchronized planning, design, and implem
The influence of holding time and distance from sample bottom on segregation and grain refinement of Ti was studied.Results show that Al-5Ti-1B FLORAVISION has an obvious effect on refinement in Al-Si alloy after 4 h holding time.The segregation of Ti shows different morphology at different positions of casting.More segregation is at the bottom of
