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

Development of a conceptual model of the hydrologic response of tropical Andean micro-catchments in Southern Ecuador [PDF]
, 2012 This paper presents a lumped conceptual model designed for simulating the rainfallrunoff response of mountain micro-catchments with natural vegetation located in the south of Ecuador. The conceptual model is mimicking the soil hydrology and consists of a

Fully 3D‐Printed Wave‐Wound Electromagnetic Motors
Advanced Materials Technologies, EarlyView.This work presents the first fully 3D‐printed wave‐wound electromagnetic motors, which are created using conductive nanoparticle inks, carbon‐filled nylon polymers, and surface mount components. These motors can achieve a stall torque of 7.62N·mmA−1$7.62 \nobreakspace N{\cdot }mm A^{-1}$ and efficiency of 28.2 %, which approaches the performance of ...

Description of the hydrochemical regime of the Dnister river (by basic ions) [PDF]
, 2019 In this part of the Dniester, water mineralization increases: Dniester - medium (379-428 mg/L); Dniester - lower (425-526 mg/L). Mineralization of the Dniester River water decreases during the spring flood (305-425 mg/L) and increases during the winter ...

Advanced Robotics Research, EarlyView.Here, we present a textile, wearable capacitive interface enabling multidirectional remote control by dynamically modulating electrode overlap and spacing via a freely gliding upper electrode. A forearm‐mounted prototype drives robotic and media tasks with 12–15 ms latency, maintains < 0.8% drift after 500 cycles, and remains stably functional at 90 ...

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

3D‐Printing Aided Rapid Prototyping of Pretensioned Tensegrity Structures for Robotic Applications
Advanced Robotics Research, EarlyView.Printing, injection molding, and assembly (PMA) is a method for rapid prototyping mesoscale, topologically complex, and tensioned tensegrity structures. In combination with PMA method, two mold design strategies: modular mold and compact channel layout, enable efficiency and scalability for tensegrity fabrication.
