Data on inhalational and potential dermal exposures during spray application of liquid biocidal products were generated. On the one hand, model experiments with different spraying devices using fluorescent tracers were carried out to investigate the influence of parameters relevant to the exposure (e.g. spraying equipment, nozzle size, direction of application). On the other hand, measurements ...

Using thermal spraying various surface coatings consisting of different material compositions can be manufactured. Besides different solid phases the resulting coating microstructure often contains a non-negligible amount of pores. In this context a roller burnishing process with a hydrostatic ball-point-tool is examined to compact the thermally sprayed coating, thereby reducing porosity. The r...

By drawing on the specific lessons learned from one case study, this paper will discuss collaboration, and issues upon knowledge communities in technical work domains. The results are based on a case study in a manufacturing process, thermal spraying, which can be characterised as very complex and technical. In order to understand the concept of knowledge communities in technical work domains I...

The presented class of products is an important addition to the existing variety of silicone based formulations for use in building protection. Compared to most silicone masonry water formulations repellents marketed so far which are usually applied as liquid this new protection system has a higher viscosity. The novel product line shows significant innovative features: l easy application with ...

1L spraying reactor with a heat exchanger outside was used to investigate the effect of spraying hydration process on storage capacity of methane in hydrate and on a methane storage rate in hydrate to solve a problem of lower gas molecular transfer rate and worse heat transfer rate. Some results showed that ethanol as a promoter had better spraying hydration rate under the liquid spraying press...

Editor – In a recent letter (1) Dr Christian Lengeler dismisses as invalid our comparisons (2) of recent trials with pyrethroid-treated nets versus trials 20–40 years ago with house spraying of non-pyrethroid insecticides. One of his reasons is that the initial intensities of malaria transmission were different in the trials compared. Lengeler may postulate that the lower intensity of transmiss...

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...
