Surface Effects on Water Storage under Dryland Summer Fallow: A Lysimeter Study

open access: yesVadose Zone Journal, 2018
Small changes in short- and long-term soil water storage can affect crop productivity in semiarid climates. To optimize tillage and residue management on silt loam soils, we compared evaporation from a range of soil surface conditions in a climate with ...

Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

Nanoplastics: Methods, Exposure and Effects on Domestic, Farm and Wild Animals

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Nanoplastics (NPs) are synthetic polymer particles ranging in size from 1 nm to 1 μm that have been identified as a major concern for ecosystems and organisms due to their plethora of negative effects. The aim of this review is to provide a comprehensive overview of the knowledge relating to exposure and effects of NPs in domestic (i.e., farm ...

An efficiency assessment analysis of a modified gravitational Pelton-wheel turbine

open access: yesJournal of Energy in Southern Africa, 2017
A Pelton-wheel impulse turbine is a hydro mechanical energy conversion device which converts gravitational energy of elevated water into mechanical work. This mechanical work is converted into electrical energy by means of running an electrical generator.

A drop in the bucket? The effectiveness of nudging healthier snacks in a supermarket in a deprived neighborhood in the Netherlands

open access: yesBehavioural Public Policy
Abstract Nudging is often proposed as a promising policy approach for improving healthy choices among lower socioeconomic position (SEP) populations. However, nudges may not suit lower SEP contexts and empirical studies are scarce. We examined the efficacy of a repositioning nudge at a supermarket in a deprived neighborhood in improving healthier ...

Microstructural characterization and heat treatment of A-286 turbine buckets

open access: yes, 2009
A-286 is an iron-based superalloy used extensively in land-based gas turbines for 2nd stage (low pressure) buckets and 1 st and 2nd stage wheels. Although A-286 may appear to some as just another austenitic stainless steel, its elevated temperature ...

The Art of Reception: Field Visits as Microcosms for Development Interventions of Non‐Governmental Organisations in Uganda

open access: yesJournal 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 ...
