The electro-spraying process can be regular and periodic, consisting of cyclical phases of initiation (meniscus, drop, and/or jet), pulsation, deformation and separation. This paper presents an experimental study on the repetition frequency of drop and/or jet ejection from the capillary end with various spraying modes during an electro-spraying process of deionized (DI) water. The influence of ...

In this report, we describe a method for the delivery of small interfering RNAs (siRNAs) into plant cells. In vitro synthesized siRNAs that were designed to target the coding region of a GREEN FLUORESCENT PROTEIN (GFP) transgene were applied by various methods onto GFP-expressing transgenic Nicotiana benthamiana plants to trigger RNA silencing. In contrast to mere siRNA applications, including ...

Flame Spray Pyrolysis (FSP) is a well investigated high temperature aerosol technique for synthesizing nano-sized metal oxide catalysts of almost all metals and transition metals by gas-to-particle conversion (Teoh et al. 2010). However, specific designs of multi-component catalysts and the controlled dispersion of catalytic material on the support are limited with this approach. Double Flame S...

Malaria is one of the most serious vector-borne diseases, affecting millions of people mainly in the tropics. Recently, a substantial decline in malaria incidence has been observed all over the world. Vector control is one of the key elements in achieving this world-wide malaria decline, with scaling up of Insecticide Treated Nets (ITNs) and the expansion of Indoor Residual Spraying (IRS) progr...

AIMS To determine haematological parameters, urine mutagenicity (on three Salmonella typhimurium strains), and DNA damage (using the comet assay) in mononuclear leucocytes of farmers before and after a one-day spraying period of pear and apple trees with the fungicide captan in usual conditions. METHODS Fruit growers were exposed to captan during the 1998 (n = 12) and/or the 2000 spraying sea...

We examined whether the spraying of soybean leaves with hydrogen peroxide (H2O2) would alleviate the symptoms of drought stress. Pre-treatment by spraying leaves with H2O2 delayed foliar wilting caused by drought stress compared to leaves sprayed with distilled water (DW). Additionally, the relative water content of drought-stressed leaves pre-treated with H2O2 was higher than that of leaves pr...

powdery mildew disease caused quality and quantity losses of sugar beet production. therefore, five spraying treatments and three sugar beet variety were conducted in split plot design with four reapplications during consecutive two years in kermanshah and mashhad regions. in order to control of disease, tridimorph fungicide was used. spraying treatments were in main plot and variety in the sub...

This article aims to address the issue of simulating plasma-jet by using an innovative computational approach namely the Lattice Boltzmann Method (LBM) from the point of view of extending the applications to simulating flows with temperature-dependent physical parameters. The work focuses on the phenomena occurring in plasma-jet that define the link between LBM lattice and physical lattice. Hig...

In this paper an innovative computational approach, namely the Lattice Boltzmann Method (LBM), is used for simulating and modeling plasma jet behaviors. Plasma jets are a high temperature flows, then all physical parameters are temperature dependent. This work aims to address the issue of simulating plasma-jet from the point of view of extending the applications to simulating flows with tempera...
