The simple heat treatment greatly improves the hardness, tensile strength and abrasion resistance of medium carbon and high C - low Cr steels. The results indicate that the material removal during abrasion is controlled by a number of factors, such as hardness, chemical composition, microstructure and heat treatment conditions. The conclusion is that the heat treated high C - low Cr steel and mild steel carburized by using coaltar pitch provide the best hardness and abrasion resistance and thus appear to be the most suitable materials for making agricultural tools.展开更多

Green development will greatly help China choose its path for economic growth. In the newly ratified Paris Agreement, the carbon emission reduction target willingly and determinedly proposed by China is very challenging. It will increase China's cost per unit of carbon dioxide emissions, slow China's economy growth, and set the upper limit for China's carbon emissions in the future. Facing these challenges, China needs to properly conduct carbon allocations under restrictions and promote green and low carbon development of the Chinese economy primarily by reinforcing structural adjustments and optimizing energy structures, upgrading industrial structures, being actively involved in international cooperation on carbon emission reduction and using other positive strategies.展开更多

The Public Administration (PA) in Italy, in particular, plays a key role to affn-m models of development oriented towards energy and environmental sustainability, thanks to a wider and more innovative vision. The PA has a dual consumer/user role, public heritage and decision maker/planner, in promoting energy efficiency at local level, in the light of specific problems and peculiarities. For several decades, initiatives have been launched at various levels to improve energy and environmental performance in the public administration. The aim of this study is to outline from a critical perspective, the state of the art of policy makers in Italy concerning energy efficiency measures in public administration. There are however many cultural, value-related, financial, technological, institutional, and operational issues in the PA sector that limit investments in energy efficiency. It should be noted that if on one hand the PA shows a lack of knowledge and is unwilling to adopt practices and systemic tools for monitoring and control, on the other, in terms of bureaucracy, the system appears to be far too complicated and costly. The multiple benefits linked to improved energy performance would therefore require that the PA rethink their organizational and functional models, put in place more flexible and less bureaucratic forms of management and a more dynamic, pervasive, and proactive approach towards initiatives that promote energy efficiency. The research is a contribution towards identifying the driving forces behind potential systems and tools for energy efficiency in the PA, highlighting both critical elements and opportunities and, in particular, the limits deriving from the technological, managerial, and organizational options available for energy eff^ciency enhancement in the sector of the Italian PA.展开更多
