The Canadian Journal of Chemical Engineering, EarlyView.Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...

Clogging of buried drip irrigation systems [PDF]
California Agriculture, 1990 Lime precipitate clogging of buried drip irrigation systems is difficult to detect and can cause problems where water quality is poor. Injecting a phosphonate was as effective as acid against clogging in two field trials, and may cost less.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Enabling a Circular Water Transition: Identifying Governance Pathways for Wastewater Reuse
Environmental Policy and Governance, EarlyView.ABSTRACT Over 80% of the world's wastewater is discharged untreated, making reuse a widely underutilised strategy for addressing water scarcity. Due to the complexity of implementing water reuse systems, supportive governance conditions are required to steer this process and overcome barriers.

EFFECTS OF DIFFERENT IRRIGATION SYSTEMS AND NITROGEN FERTILIZER SOURCES ON POTATO GROWTH AND YIELD [PDF]
Journal of Soil Sciences and Agricultural Engineering, 2004 The effect of the applied irrigation system and nitrogen fertilizer sources are two major issues for the growth and yield of potato. A field experiment was conducted on a clay loam soil at Mansoura University Farm during the late winter planting ...

Environmental Policy and Governance, EarlyView.ABSTRACT This study examines how farmers perceive and respond to climate policy risk in the context of drought and argues that understanding such responses is as important as understanding farmer reactions to the biophysical impacts of climate change.

The adoption of low-cost low head drip irrigation in small-scale farms in Kenya [PDF]
, 2003 Population growth and development will increase the demands on water resources in Africa, and hence there is a need for agriculture to use water efficiently. Drip irrigation is widely promoted for water saving at the farm level.

Environmental Policy and Governance, EarlyView.ABSTRACT Freshwater availability is a critical climate change challenge in coastal delta regions. This challenge requires a transformative change toward circular water management. While experimentation and collaborative governance are recognized as enablers of transformative change, their interaction remains complex and insufficiently understood ...

Formalization of fertigation module parameters in drip irrigation systems
Land Reclamation and Hydraulic Engineering, 2023 Purpose: to formalize the parameters on which the choice of optimal fertilizer application rates depends with fuzzy sets for constructing a fuzzy model and a control system for the fertigation module. Materials and methods. The use of Soft Computing methods is required by the need to represent the input variables values in the form of fuzzy sets, with ...
