Liquid spray pollination (LSP) is widely used in fruit tree pollination. However, the LSP parameters that affect pollen activity are still unclear. In this study, three mainly were studied: storage time of suspensions, sprayer and unmanned aerial vehicle (UAVS) downwash airflow. addition, include recirculation device, pump type, spraying pressure, nozzle size revolutions per minute (rpm) rotary...

The relevance of the research is related to development a new type renewable energy source ‒ vortex wind device with vertical axis rotation without guidance mechanisms. main purpose study develop turbine using mathematical modeling motion and laboratory experiments on model. object consisting concentrator curved channels, inside which there wheel, pipe mounted concentrator. calculations are bas...

This research aimed to modify the rotary plow into a bed-making tool. The performance test of tool was carried out on sandy and loamy land by experimental method. dimensions bed including length, width, height as well time are also measured in test. has total length 182 cm, right left sides each 51 width 25 cm 30 cm. four-wheel tractor at distance 10 m m, making performed 5 times. Experimental ...

This work is a continuation of experimental and computational studies of the internal flow field of a large-scale Danfoss atomizer presented at an earlier ILASS conference [1,2]. Fluent 6.1 is used to simulate the flow through the large-scale atomizer. The two-phase flow is modeled using three approaches: 1) a volume of fluid (VOF) method using a laminar flow assumption, 2) a VOF method using l...

A desire for higher speed and performance in molecular profiling analysis at a reduced cost is driving a trend in miniaturization and simplification of procedures. Here we report the use of a surface acoustic wave (SAW) atomizer for fast sample handling in matrix-assisted laser desorption ionization mass spectrometry (MALDI MS) peptide and protein profiling of Islets of Langerhans, for future t...

Aim of the present study was to investigate the impact of atomization and drying on the functionality of emulsions with an oil/water-interface (o/w-interface) consisting of beta-lactoglobulin (single layer emulsion) and sequentially adsorbed pectins with varying degree of methylation at pH<pI (bilayer emulsions). Thus, the emulsion systems were characterized with respect to their behavior durin...
