WATER USERS ASSOCIATIONS IN ARMENIA: CURRENT SITUATION AND FUTURE TRENDS
Experiences of Water Consumers Cooperatives accumulated in Armenia during the past six years have been mixed. Some cooperatives have provided evidence of being capable of organizing themselves and responding to the needs of their members more effectively than any central governmental organization. However, many other aspects are still unresolved. Created in 2001, the State Committee for Water Economy (SCWE) agreed recently to follow a more participatory approach in establishment of Water Users Associations and, on the basis of positive experiences worldwide, SCWE is willing also to scale up the process to the level of Water Users Federations.
Water users associations in Armenia : analysis of current situation and future trends
The experience of Water Consumers Cooperatives accumulated in Armenia during the past six years has been mixed. On one hand, some of the cooperatives have provided evidence of being potentially capable of organizing themselves and responding to the needs of their members more effectively than any central governmental organization. On the other hand, many other aspects are still unresolved. Created in 2001 the State Committee for Water Economy (SCWE) agreed recently to follow a more participatory approach in establishment of Water Users Associations and, on the basis of positive experiences worldwide, SCWE is willing also to scale up the process to the level of Water Users Federations.
A New Vacuum Pressure Infiltration CFRP Method and Preparation Experimental Study of Composite
In order to prepare a carbon-fiber-reinforced polymer composite (CFRP) with ideal microstructure and properties, a new vacuum pressure infiltration CFRP method is proposed based on an analysis of existing CFRP preparation process methods. Research on composite material preparation systems was carried out by using this new method principle. The system mainly includes a fiber pre-forming module, a vacuum heating infiltration module, a hot-press curing molding module, and a data acquisition control module. Under the conditions of natural curing at 0 MPa + 6 h + 25 °C, vacuum heating curing at –0.05 MPa + 30 min + 80 °C, and hot-press curing at 0.7 MPa + 5 min + 50 °C, a two-dimensional (2D) CFRP with excellent microstructure and properties was successfully prepared. Observing the microstructure of the prepared composite material, it can be found that the inside of the composite material was sufficiently and uniformly infiltrated, and common preparation defects such as holes and delamination were effectively controlled. Through the performance test, the bending strength of the material reached 790 MPa.
