Electrostatic Effects of Corona Discharge on the Spectrum and Density Evolution of Water Droplets in Air [PDF]

IEEE Access, 2020
As one of the emerging application areas of the corona discharge technique, rain enhancement induced by atmospheric air ionization has made a great breakthrough. Although natural rainfall modified by artificial ionization was successfully observed via the statistical data of field experiments, deficient efforts have been devoted to the research on the ...

Droplet activation, separation, and compositional analysis: laboratory studies and atmospheric measurements

, 2011
Droplets produced in a cloud condensation nuclei chamber (CCNC) as a function of supersaturation have been separated from unactivated aerosol particles using counterflow virtual impaction.

SPECTRUM AND VELOCITY OF DROPLETS OF SPRAY NOZZLES WITH AND WITHOUT AIR INDUCTION [PDF]

Engenharia Agrícola, 2018
ABSTRACT The aim of this study was to evaluate the spectrum and the velocity of droplets produced by nozzles with and without air induction, under different pressures and flow rates. The experiment was conducted in a completely randomized design with five replications, in a factorial 2 x 3 x 3 (two spray nozzles, three flow rates and three operating ...

Effects of Adjuvants on Spraying Characteristics and Control Efficacy in Unmanned Aerial Application

Agriculture, 2022
Pesticide application by unmanned agricultural aerial vehicles (UAVs) has rapidly developed in China and other Asian counties. Currently, tank-mix spray adjuvants are usually added into pesticide solutions to reduce spray drift and facilitate droplet ...

Comparative Evaluation of Ultra-Low-Volume Nozzle Configurations for UAV Spraying in Mango Orchards Under Semi-Arid Conditions in Northern India

Biology and Life Sciences Forum
Efficient pesticide delivery in mango orchards is hindered by tall canopies and dense foliage. This study evaluated two ultra-low-volume (ULV) nozzles—TeeJet XR and HYPRO rotary—mounted on an indigenous multirotor drone during flowering and fruit-set ...

SPRAY DEPOSITION FROM AN UNMANNED AERIAL VEHICLE ON A COFFEE CROP [PDF]

Engenharia Agrícola
The use of unmanned aerial vehicles (UAVs) to apply pesticides has grown significantly, but technical data to support improvements in application efficiency are lacking, especially for perennial crops.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Activity-induced droplet propulsion and multifractality

Physical Review Research, 2023
We elucidate the crucial role that confinement plays in collective and emergent behaviors in active- or living-matter systems by developing a minimal hydrodynamic model, without an orientational order parameter, for assemblies of contractile swimmers ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
