TNO has expanded its 30 kW HEL research facility with the capability to monitor specular and diffuse reflections of the laser beam. A capture screen and high-speed camera focus on dynamic specular reflections, while 15 individually placeable probes monitor the diffuse component under different angles. This paper introduces the reflection...

Ricin is a proteinaceous toxin, listed on the schedules of both the chemical and biological weapons conventions. The ease of accessibility to the Ricinus communis plant and toxin extraction makes ricin a viable concern for use of intentional release and causal effects. The adverse effects following exposure to the toxin are caused by the...

Fielding TNO’s LPT (Laser Propagation Testbed) for the first time in an international trial, a 3.6 km optical propagation path was created in a maritime environment between the city of Den Helder and the island of Texel in the Netherlands. Using a 1 W, 1556 nm laser beam, atmospheric propagation was investigated by capturing the resulting beam...

A 1.55µm Laser Propagation Testbed (LPT) has been deployed over a 3.5 km stretch of open water between the port of Den Helder and the island of Texel in The Netherlands. The laser intensity and beam profile have been measured after propagation and reflection off a capture plate. Supplementing data was provided by large-aperture scintillometers,...

Background Pesticides can be transported from the site of application to homes via different routes and lead to exposure of residents, raising concerns regarding health effects. We built a deterministic model framework (OBOmod) to assess exposure of residents living near fields where pesticides are applied. Methods OBOmod connects five...

This paper investigates whether immersion in a game-based experiment can be used to observe authentic behavior, for example in the case of studying extreme behaviors under unfamiliar circumstances. A graphic adventure game (Opponent Immersion Game) was developed, in which participants could experience and act on various known risk factors and...

Contemporary hostile actors are increasingly attempting to destabilize targeted states’ civilian domains via malign influence activities. With this civilian focus, societal destabilization is at least partly psychological. However, empirical evidence of a psychological dimension to societal destabilization is lacking. We assess the potential of...

We have developed an SI-traceable narrow-band tunable radiance source based on an optical parametric oscillator (OPO) and an integrating sphere for the calibration of spectroradiometers. The source is calibrated with a reference detector over the ultraviolet/visible spectral range with an uncertainty of < 1%. As a case study, a CubeSat spectro...

Food insecurity is a growing concern due to man-made conflicts, climate change, and economic downturns. Forecasting the state of food insecurity is essential to be able to trigger early actions, for example, by humanitarian actors. To measure the actual state of food insecurity, expert and consensus-based approaches and surveys are currently...

Hostile political actors frequently engage in malign information influence, projecting antagonistic strategic narratives in targeted societies to manipulate the information environment and distort the perceptions of the citizens. Research examining malign information influence is growing, but more attention could be given to its psychological...

Violent extremism is associated with an intricately linked network of variables. Existing psychological models and research tend to either focus on specific forms of violent extremism or take a broad perspective. We propose an abstract model for the path towards violent extremism that allows for specification when needed; the General Needs and...

Method of performing atomic layer deposition. The method comprises supplying a precursor gas towards a substrate, using a deposition head including one or more gas supplies, including a precursor gas supply. The precursor gas reacts near a surface of the substrate for forming an atomic layer. The deposition head has an output face comprising the...

Om het coronavirus te bestrijden moeten overheid en burgers samenwerken. De overheid kondigt daarbij maatregelen af om het virus in te dammen. Maar de tijd is voorbij dat burgers maatregelen blindelings opvolgen. Interventies die gestoeld zijn op kennis over menselijk gedrag zijn beter dan handhaving om gewenst gedrag af te dwingen.
