Abstract: A photobioreactor is described for cultivating phototrophic organisms and in particular a mat, as can be used in one such photobioreactor. The mat has a plurality of first fibres which are light conductive along their longitudinal direction and are constructed to decouple light conducted in the longitudinal direction laterally, at least somewhat transversely to the longitudinal direction. The mat furthermore has a plurality of second fibres which are electrically conductive along their longitudinal direction. With the aid of one such mat, light can on the one hand be coupled in the interior of a photobioreactor. On the other hand, a travelling electric alternating field can be generated by applying a suitable polyphase voltage by means of a voltage source with the aid of electrically conductive second fibres. This alternating field can act on electrically charged particles.

Abstract: An aircraft wing has a spoiler movable from a reference position with a deflection angle ?ref to a given target deflection angle ?target by an actuator powered mechanism. An upstream edge of the spoiler is interconnected with the aircraft wing exclusively via a strip element made of a resiliently flexible material and via the actuator powered mechanism. A downstream edge of the strip element extends along the whole or at least along a major part of the upstream edge of the spoiler. The actuator powered mechanism is constructed and arranged such that, while moving the spoiler, the strip element is bent with a constant strain along the strip element. A cross-section of the strip element for all deflection angles ? assumes the form of a ring segment with a radius R(?) at least within a given margin of failure, with ?, ?target, ?ref?[??1; ?2].

The first functional unit is designed as a static functional unit that in each of the plurality of operating modes of the circuit carries out a consistent function. The second functional unit is designed as an adaptable functional unit that is designed to be configured, prior to the circuit being put into service, according to a first configuration of a plurality of different configurations and during the operating time of the circuit to maintain the first configuration so that the first configuration of the second functional unit defines the predeterminable operating mode of the circuit. This makes it possible to reduce the verification expenditure for the circuit because verification can be limited to the adaptable functional unit.

Abstract: A method of solar occultation, and in particular solar coronagraphy, employing a spacecraft 200 is disclosed. The spacecraft is controlled to achieve a position within a target zone relative to a celestial body, such as the Moon, such that the celestial body occults the Sun, allowing observations of the Sun or the space around the Sun, and in particular the Sun's corona, to be made from the spacecraft. The spacecraft has an orbit 40 around the Earth in a plane S, which like the Moon's orbit 20 in plane M, is inclined relative to the ecliptic plane E. Once inside the target zone, the spacecraft's orbit is controlled such that it remains in the target zone for longer than it would otherwise. This is achieved through the orbit within the target zone being at least partly non-Keplerian, when the orbit is under the influence of spacecraft translational thrust for example.
