Sunflower is the main oil crop in Russia. Sunflower plantings occupy more than 95% of the area under oil crops and annually make 7.07% of the area under grain crops. The urgent problem is the loss of oilseeds behind the header during sunflower harvesting which, according to agro-technical requirements, should not exceed 2.5% of the actual yield. The article presents the average loss of oilseeds behind various sunflower harvesting attachments. The analysis of rationality of their use depending on the area under sunflower plantings is given. The design is offered and the scheme is substantiated of the performance of an auger-reel for sunflower harvesting attachment. The developed auger-reel is equipped with a winding, which allows reducing the acceleration of the sunflower head movement during the harvesting and minimizing the loss of oilseeds behind the header to 0.63%. The results of the production tests of the developed attachment with “Niva” SK-5-M-1 and ACROS 530 combine harvesters are presented. Their comparison with the average losses of oilseeds using different by design attachments is given.

The transition to the construction facilities design, that involves the application of information models, strengthens the requirements for the comfortable perception of such models by their users and consumers. The presented research work has a description of an information model that accompanies a construction facility at each stage of its lifecycle. The article addresses the usability notion in the context of the emergency scenarios’ information modelling at construction facilities. The co-authors offer an infographic model of a building information model lifecycle. The information model lifecycle analysis has given an opportunity to identify the production and consumption stages of an information model. Positions of the stakeholders, involved in the usability engineering of an information model, have been determined.
