Design of the flexible switching controller for small PWR core power control with the multi-model

, 2020
Small PWR can be used for power generation and heating. Considering that small PWR has the characteristics of flexible operating conditions and complex operating environment, the controller designed based on single power level is difficult to achieve the

Passive Safety Systems in Advanced PWRs

Science and Technology of Nuclear Installations, 2009
Passive safety systems have been widely applied to advanced water-cooled reactors (WCRs), to enhance the safety of nuclear power plants. For the near term and medium term, the Chinese government decided for advanced pressurized water reactors with an extensive usage of passive safety systems.

Brain reward function in young people with cannabis use disorder: A functional magnetic resonance imaging study

Addiction, EarlyView.
Abstract Background and Aims Cannabis use disorder (CUD) affects ~50 million people globally. Neuroscientific theories suggest that a blunted neural response to non‐drug rewards is a hallmark of substance use disorders; however, this remains untested in CUD. The current study tested whether brain reward system responses to the anticipation and feedback

From trade‐offs to trade: The effects of framing and social norms on waste supply chain coordination

Decision Sciences, EarlyView.
Abstract The world generates substantial waste that could serve as feedstock, but often inefficiencies in waste exchange arise, caused by a lack of coordination among companies. When trading waste reuse, negotiators must manage the trade‐offs between supply chain, personal, and environmental outcomes. Unlike studies focusing on monetary incentives (e.g.

Histopathologic Validity and Clinical Reliability of Wolters Classification of Pulpitis: An Exploratory Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim Wolters' classification of pulpitis has been proposed to classify pulpitis into 4 categories (initial, mild, moderate, severe), aiming to guide clinicians to implement the relevant vital endodontic treatment. The main objective of this study was to test the histologic validity and clinical reliability of the Wolters classification ...

Genetic Determination of Maternal Behaviour in Pigs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...

How Educational Leaders Think About Intersections of Identities and Disciplinary Learning in Science

School Science and Mathematics, EarlyView.
ABSTRACT American science education leaders play critical roles in promoting equity in education, but little is known about how they understand everyday classroom interactions where inequities related to intersectionality are evident. This study examines science leaders' sensemaking about a scenario depicting the experiences of a group of American ...
