An Increasing Misalignment Between Crop Distribution and Environmental Resources Under Climate Change in China

open access: yesAdvanced Science, EarlyView.
Climate change reshapes the spatial alignment between crop production and environmental resources. Using multi‐source data and a crop model, integrated climatic, water, and soil endowments for maize and wheat are quantified and compared with harvest distributions.

Impacts of model calibration on high-latitude land-surface processes: PILPS 2(e) calibration/validation experiments [PDF]

open access: yes, 2003
In the PILPS 2(e) experiment, the Snow Atmosphere Soil Transfer (SAST) land-surface scheme developed from the Biosphere-Atmosphere Transfer Scheme (BATS) showed difficulty in accurately simulating the patterns and quantities of runoff resulting from ...

Developmentally Inspired, Mechanical–Metabolic Dual Gradient Osteochondral Constructs Bridging Regeneration and Therapeutic Screening

open access: yesAdvanced Science, EarlyView.
A developmentally inspired osteochondral construct integrates mechanical and metabolic dual gradients within a 3D‐printed platform. Human MSC spheroids are spatially directed to form cartilage–bone interfaces, enabling evaluation of regeneration without biochemical reagents and assessment of drug responses. This physiologically relevant, phase‐specific

Runoff vs. plurality:the effects of the electoral system on local and central government behaviour [PDF]

open access: yes, 2012
Plurality and runoff systems oer very different incentives to parties and coalition of voters, and demand different political strategies from potential candidates and chief executives.

A Review Of Road‒Related Soil Erosion: An Assessment Of Causes, Evaluation Techniques And Available Control Measures

open access: yesEarth Sciences Research Journal, 2015
Road construction has increased significantly worldwide in the last decades to meet the demands of the increasing human population and this has led to serious soil erosion problems, the bulk of which is unaccounted for, especially in the developing world.

Fabrication and evaluation of a reservoir tillage machine to reduce runoff from farms with sprinkler irrigation systems [PDF]

open access: yesJournal of Agricultural Machinery, 2016
Introduction Nowadays, in a lot of farm land due to reasons such as high density, heavy textured soils, steep terrain and a large body of water at each irrigation, rapid and complete absorption of water in the soil does not happen and runoff will be ...

Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

open access: yesAdvanced Science, EarlyView.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

On the simulation of infiltration- and saturation-excess runoff using radar-based rainfall estimates: Effects of algorithm uncertainty and pixel aggregation [PDF]

open access: yes, 1998
The effects of uncertainty in radar-estimated precipitation input on simulated runoff generation from a medium-sized (100-km2) basin in northern Texas are investigated.

Estimating the characteristics of runoff inflow into Lake Gojal in ungauged, highly glacierized upper Hunza River Basin, Pakistan [PDF]

open access: yes, 2013
Motivated by the potential flood outburst of Lake Gojal in the ungauged highly glacierized (27%) upper Hunza River Basin (HRB) in Pakistan that was dammed by a massive landslide on 4 January 2010, we attempt to analyze the characteristics of water inflow

Modelling nitrogen fate from urea applied to near-trench rice paddy field

open access: yes浙江大学学报. 农业与生命科学版, 2007
A simple model based on the theory of ‘first-order reaction’ kinetics and water-nitrogen coupled balance was developed to quantify N losses from urea applied to a near-trench rice paddy field, considering all the N transformations such as urea hydrolysis,
