Comparison between standard and drift reducing nozzles for pesticide application in citrus: Part II. Effects on canopy spray distribution, control efficacy of Aonidiella aurantii (Maskell), beneficial parasitoids and pesticide residues on fruit [PDF]
, 2017 Venturi nozzles are often recommended to reduce drift, which is one of the major pollution sources caused by the application of plant protection products on high growing crops. The coarse droplets produced by this type of nozzle could however also affect

Advanced Engineering Materials, EarlyView.Stabilization of L‐PBF Ni50.7Ti49.3 under low‐cycle loading was investigated. Recoverable strain after cycling was dependent on the amount of applied load. Recovery ratio was 53.4% and 35.1% at intermediate and high load, respectively. The maximum total strain reached 10.3% at a high load of 1200 MPa.

Advanced Engineering Materials, EarlyView.Creep experiments at 900°C on coarse‐grained steel‐ceramic composites containing recycled magnesia reveal that higher ceramic volume fractions significantly enhance the creep resistance. Detailed EBSD investigations identify subgrain formation in the steel matrix as the dominant deformation mechanism.

Investigation of rotary sprayers for boom sprayers
, 2022 Химическата растителна защита е и ще продължава да бъде основен фактор в съвременно-то земеделие. Разходите за нейното провеждане са значителни и всяко тяхно намаляване има ефект, както в икономически така и в екологичен аспект. Значителна част от тях са следствие и на неудачно подбрани технически средства и технологии съобразени с конк-ретните условия.

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...
