Cold water intake inhibits colonic motility partially through oxytocin-oxytocin receptor signaling in the myenteric nervous system pathway, which is estrogen dependent.
The ‘Push’ of ERP (Enterprise Resource Planning) seems to be contradictory with the ‘Pull’ of Lean manufacturing; actually they have mutual promotion in production. The dual implementation of ERP and Lean is inevitable direction in the enterprise’s development. This paper first explains the difference and interrelation between ERP and Lean Manufacturing, and discusses the mutual promoted effects. Then focus on “how to accomplish the dual implementation?” To answer this question, this paper mainly put forward three points: firstly strength the centralized management of all kinds of data and information in manufacture; then fuse ERP with Kanban; lastly build business process mixed by Pull-based mode and Plan-controlled mode. Through the above methods, ERP links with Lean to boost each other. Thus enable enterprise to gain a competitive advantage in manufacturing.
Mechanical strengths and electrical conductivity are the very important engineering properties of lightweight aluminum (Al) alloys used in automobiles, especially for battery-powered electric vehicles (BEV). However, the main issue is that the mechanical properties and the electrical conductivity of Al alloys are mutually exclusive. This study aims to simultaneously improve both the tensile properties and the electrical conductivity of the squeeze as-cast Al-6wt% Si-3wt% Cu by modifying its microstructure with the addition of nickel (Ni) and strontium (Sr). In comparison to those of the alloy free of Sr and Ni, the additions of 0.03 wt.% Sr and 0.5 wt.% Ni in the Al-6Si-3Cu alloy significantly improved the ultimate tensile strength, yield strength and electrical conductivity. This was because the addition of Ni element, as a transition element, collaborated with Cu to form fine intermetallic Al-Cu-Ni phases for dispersion strengthening. Also, the modification of the Si morphology from micron needles to nanoparticles by the Sr addition enhanced both the strengths and electrical conductivity of the developed alloy.
Under the fiber hybrid effect, the merits of organic and inorganic fibers were integrated. The appropriate organic and inorganic fibers were chosen to prepare the non-asbestos gasket which meets the usage requirements and has a good cost performance. The ratio of basic craft and materials for industrial production were obtained. Results indicate the new non-asbestos gasket which is made by non-asbestos fibers and enhanced rubber adhesive has reached the performance of similar international products and has formed our unique non-asbestos sealing materials.
In recent years, Asbestos fibred gaskets are gradually replaced because of its serious health damage. Non-asbestos gasket is a heated discussion nowadays and the research of it will be of great significance. The present thesis firstly expounds the sealing principle of gasket, and then explains the main property index and its characterization method. Finally analyses and summarizes the main factors which we must consider to improve the sealing property of non-asbestos fiber gasket, and points out the main research ways of non-asbestos in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
