Ocean Governance and Marine Conservation: Institutional Work as a Lever for Ocean Sustainability
Environmental Policy and Governance, EarlyView.ABSTRACT Ocean governance presents one of the most complex environmental policy challenges of our time, requiring coordinated action across multiple scales, sectors and stakeholder groups. This paper applies institutional work theory to systematically examine how actors create, maintain and disrupt the governance arrangements underpinning ocean ...

Modal Analysis of the Cycloid Gear Pump based on Pro/E and ANSYS
Jixie chuandong, 2015 By using the three-dimensional CAD software Pro/E,the three-dimensional geometric model of a certain type of cycloidal gear pumps is established,then the mesh generation of them is carried out by using Hypermesh,and it is simplified and imported into ...

Irrigation and Drainage, EarlyView.ABSTRACT Long‐term economic analyses of variable rate irrigation (VRI) strategies were performed compared with uniform irrigation management (UIM) in a reference production field using the AquaCrop model. Five strategies to trigger irrigation were as follows: (Field Capacity‐VRI, Driest Soil Trigger‐VRI, Water Mining‐VRI, Conventional Uniform ...

Active Design and Characteristic Analysis of Gear Pump with Low Pulsation
Jixie chuandong, 2017 In order to solve the problem of large flow ripple of gear pumps,an active design method for gear pumps with low flow pulsation is proposed. The basic design thought is to control the shape of the tooth profile by specifying the values of the flow ...

Integrated CFD-FEM approach for external gear pump vibroacoustic field prediction
Frontiers in Mechanical EngineeringIn this work, a three-dimensional fluid-structural and vibro-acoustics coupled model of a gear pump is presented. Gear pumps represent the majority of the positive displacement machines used for flow generation in fluid power systems.

Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND Chlorinated aliphatic hydrocarbons such as trichloroethylene (TCE) are persistent groundwater contaminants due to improper disposal and low biodegradability. This work presents an innovative bioelectrochemical system for the integrated reductive/oxidative removal of TCE from contaminated water, implemented in a single tubular ...

Journal of International Development, EarlyView.ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...
