Past, present and future of local crop evolution

PLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).

Simulation of water hammer in long distance water transmission pipeline based on Flowmaster

Journal of Physics: Conference Series
Long distance water transportation projects are widely used in balancing water resources and other fields. However, the opening and closing of valves often causes significant pressure changes in the pipeline, whether it is positive or negative pressure ...

Breeding for multi‐stress resilience in crops: Myth or possibility?

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change threatens millions of farmers worldwide by exposing crops to multiple concurrent or sequential environmental stresses such as drought, heat, waterlogging, and diseases. Although crops have long been selected under naturally occurring multi‐stress conditions, breeding pipelines largely focus on optimal or single‐stress environments ...

Japanese irogane alloys and patination – a study of production and application [PDF]

, 2009
Japanese metalworkers use a wide range of irogane alloys (shakudo, shibuichi), which are colored with a single patination solution (niiro). This approach allows different alloys to be combined in one piece and patinated, producing a multi-colored piece ...

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 ...

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.

Attending to Preservice Teachers' Assets: Beliefs and Practices for Supporting Expansive Sensemaking in Elementary Science

Science Education, EarlyView.
ABSTRACT Preservice elementary science teachers' beliefs and practices influence the kinds of adaptations they make to curriculum materials and the extent to which they are able to enact justice‐oriented science lessons. Through this qualitative study, we explored the beliefs and practices of five focal preservice teachers through an analysis of their ...
