Negative pressure protection with one-way surge tanks in bidirectional water delivery systems

Water supply : the review journal of the International Water Supply Association
Water hammer protection is one of the key factors for the safe operation of the long-distance water delivery systems, which has lots of useful results. However, the protection experiences for bidirectional water delivery systems using the same pipeline

Poly(L‐Lactide‐Co‐ε‐Caprolactone)/glass Fiber Composites: Toward Improved Mechanical Properties of Polylactide‐Based Composites

Polymer Composites, EarlyView.
Enhanced impact strength in PLLA‐based composites via ε‐caprolactone incorporation in the matrix. ABSTRACT Inherent brittleness and limited toughness of polylactide (PLA) restrict its use in high‐performance applications. To overcome these limitations, poly(L‐lactide) (PLLA) is often blended with more ductile thermoplastics or chemically modified ...

Dynamic characterization of water hammer in gangue fly ash slurry pipelines during valve closure

Scientific Reports
In the process of coal-filling mining, the gangue fly-ash slurry (GFS) needs to be transported over a long distance to reach the gobs. The abrupt closure of the valve during the transportation of GFS can result in a water hammer that significantly ...

Comparative Assessment of Energetic Plasticizers Including NFPEG3N3 in a GAP/HMX Formulation: Mechanics, Stability, Combustion, and Performance

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT We examine the new energetic plasticizer 3‐(2‐(2‐(2‐azidoethoxy)ethoxy)ethoxy)‐4‐nitro‐1,2,5‐oxadiazole (NFPEG3N3), three reference compounds (BDNPA/F, Bu‐NENA, and DNDA‐57), and a plasticizer‐free control in a fixed HMX/GAP composite. NFPEG3N3 provides the strongest low‐temperature properties, yielding the lowest formulation glass transition ...

Teachers' Customizations of Storyline Science Curriculum: Adapting for Their Students and Instructional Contexts

Science Education, EarlyView.
ABSTRACT Curriculum materials can play an essential role to help teachers shift their instruction. However, curricular enactment does not look identical in every classroom, because teachers need to be responsive to their students. In this study, we investigated the customizations teachers made while enacting storyline science curriculum.
