An annotated checklist of the Balinese Cydnidae is provided. Three species (Chilocoris adelphus, Macroscytus dominiqueae, M. javanus) are recorded for the first time from Bali, including the first Indonesian record for M. dominiqueae. Fromundus pygmaeus is recorded for the second time from the island. Our study increases the number of Cydnidae recorded from Bali to seven, and that known from Indonesia to 58.
The paper presents the experimental research and numerical simulations of reinforced concrete beams under torsional load. In the experimental tests Digital Image Correlation System (DIC System) Q-450 were used. DIC is a non-contact full-field image analysis method, based on grey value digital images that can determine displacements and strains of an object under load. Numerical simulations of the investigated beams were performed by using the ATENA 3D – Studio program. Creation of numerical models of reinforced concrete elements under torsion was complicated due to difficulties in modelling of real boundary conditions of these elements. The experimental research using DIC can be extremely useful in creating correct numerical models of investigated elements. High accuracy and a wide spectrum of results obtained from experimental tests allow for the modification of the boundary conditions assumed in the numerical model, so that these conditions correspond to the real fixing of the element during the tests.
