Opis:
The growth and saponin accumulation were measured in two lines of transgenic hairy roots of Platycodon grandiflorum, Pl 6 and Pl 17, cultured for 8 weeks in 250-ml shake flasks containing 50 ml of hormone-free woody plant medium supplemented with 40 g/l sucrose and in the Pl 17 line cultured for 12 weeks in a 5-l mist bioreactor containing 1.5 l of the same medium. With both methods, the growth of transgenic hairy roots was assessed as both fresh and dry weight and the biomass growth was correlated with the conductivity and sucrose uptake. The accumulation of saponins was measured and compared with that in roots derived from the field cultivation. The saponin concentrations were significantly higher in the two hairy root lines cultured in shake flasks [6.92 g/100 g d.w. (g%) and 5.82 g% in Pl 6 and Pl 17, respectively] and the line cultured in the bioreactor (5.93 g%) than in the roots derived from the field cultivation (4.02 g%). The results suggest that cultures of P. grandiflorum hairy roots may be a valuable source for obtaining saponins.

Opis:
The paper presents the analysis of the influence of fasteners and connections flexibility on displacements of symmetrical single-bay pitched-roof steel building, including trapezoidal cladding acting as a diaphragm. The purpose of the article was to compare numerical models with and without taking into consideration fasteners and connections flexibility in order to observe the differences in transverse stiffness of the building during modifying model from the simple one to more complex and precise. The analyses were carried out for the 3D structure. Fasteners and connections were substituted by equivalent beam finite elements. Corrugated sheets were replaced by three types of equivalent orthotropic shell models and the influence of the choice of the model on the stiffness of the building was observed. The results showed that in the analysed structure the flexibility of fasteners and connections has negligible effect on transverse displacements of the building in the case of four sides fastening of the sheeting, however in the case of two sides fastening the influence significantly increases.

Opis:
The aim of this paper is to present the Erotetic Reasoning Corpus (ERC) which constitutes a data set for research on natural question processing. We describe the theoretical background, linguistic data and tags used for the annotation process. We also discuss the potential areas in which the ERC can be exploited.
