JIT spraying allows an attacker to subvert a JustIn-Time compiler, introducing instruction sequences useful to the attacker into executable regions of the victim program’s address space as a side effect of compiling seemingly innocuous code in a safe language like JavaScript. We present new JIT spraying attacks against Google’s V8 and Mozilla’s SpiderMonkey JavaScript engines on ARM. The V8 att...

A nanostructured hydroxyapatite (HA) feedstock was thermally sprayed on Ti–6Al–4V substrates via high velocity oxy-fuel (HVOF process). The particle temperature and velocity for the HA particles in the HVOF jet were monitored during spraying and found to be 1826± 346 ◦C and 638± 82 m/s, respectively. The bioactivity of the coating was investigated in a simulated physiological environment, as an...

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...

ABSTRACT The correct deposition of spray along the canopy is important for phytosanitary control in coffee plants; however, structure plant makes this distribution difficult. This study aimed to evaluate a tracer on leaves and fruits cultivation, with respect application rate type hydraulic nozzle, as well use an electrostatic spraying system. A hydropneumatic sprayer was used, nozzles empty co...

this article studied static deflection, natural frequency and nonlinear vibration of a clamped-clamped microbeam under discontinues electrostatic actuation. the electrostatic actuation was induced by applying ac-dc voltage between the microbeam and electrode plate. in contrast to previous works, it was assumed that length of the electrode plate was smaller than that of the microbeam. in additio...

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...
