Hydrogen leak detection device Patent

Development of device for detecting hydrogen in ambient environment

Sniffer used as portable hydrogen leak detector

Sniffer type portable monitor detects hydrogen in air, oxygen, nitrogen, or helium. It indicates the presence of hydrogen in contact with activated palladium black by a change in color of a thermochromic paint, and indicates the quantity of hydrogen by a sensor probe and continuous readout

Newtonian gravity and resonance on de-Sitter branes

A dS brane on the boundary between two five-dimensional spacetimes is determined. We consider asymmetric scenarios with AdS${}_5$ vacua at each side of the dS brane; and as a result, a resonant mode inside of the spectrum of the gravitational fluctuations is found. We analyze the deviations to the Newton potential generated by the gravitational excitations, finding that, for scenarios with large values of the cosmological constants, the contribution of the resonant mode is exponentially suppressed. However, when one of the vacua is null, the resonant mode belongs to the light states set of the gravitational fluctuations and five-dimensional gravity is recovered on the dS brane.Comment: 6 pages, 2 figure

Mapping Specialisation and Fragmentation of Regulatory Bodies

The objective of the Flemish database is to determine the current level of proliferation of regulatory bodies and to map how regulatory regimes are structured (i.e. what kind of organizations are involved and what are their characteristics?). This paper explores whether there are ‘groups’ of regulators who share certain characteristics with other members of the same group, but differ from other groups. In specific, we test whether the sector in which a body is active and the level of government to which it belongs, have an impact on the organisational form of the body and the tasks it performs. We find that economic regulators differ significantly from other areas. They are more insulated from politicians, are more specialised and seem to have a relatively strong legal mandate. The level of government seems to be a relevant explanatory factor as well. Federal bodies are more insulated from government than other levels. In addition, they are more specialised in regulation and have a rather limited legal mandate. The results confirm the relevance of comparing different regulatory areas and levels of government.
