A support structure for an aircraft, includes one or several bar elements and one or several junction elements. At least one bar element includes a transition region which can be made to engage at least one junction element. When the transition region of the bar element engages at least one ...
A door has an outer fixed frame hinged with a hinged wooden inner frame for a glass door or window. The hinged inner frame (2) has a profiled cover strip that projects beyond the rear end-face. The strip sides are of different length and hold the glass in position....
A structure (51) for wing and/or frame of a window frame comprising a first frame profile (52), made of metal, to which a second frame profile (70), made of plastic, is fixed by means of first engaged elements (64, 66, 76, 78). A first wing profile (56), made of metal, is...
This paper shows how uncertainty can be propagated through a computer model when the input data consists of uncertainty affected by imprecision and randomness. The proper orthogonal decomposition (POD) is used to determine the dominant air pressure distributions on a wing, and the uncertainty in the...

Bacterial σI factors of the σ70-family are widespread in Bacilli and Clostridia and are involved in the heat shock response, iron metabolism, virulence, and carbohydrate sensing. A multiplicity of σI paralogues in some cellulolytic bacteria have been
All 18 classrooms of a former village school have been converted into 22 hotel-style guest bedrooms. The secondary wing of the complex is now home to a cafe, several dining rooms and a rooftop canteen, while its previous playground gave way to a swimming pool. ...
