The purpose of this report is to propose possible engineering solutions for the construction, reconstruction and modernization of the existing irrigation infrastructure in our country . These solutions can assist beneficiaries in the application process for the Rural Development Program 2014-2020 under sub-measure M4.3 "Support for investment in infrastructure related to the development, modernization or adaptation of agriculture and forestry". In order to achieve this goal, the state of the existing irrigation infrastructure has been analyzed and the specifics of the irrigation systems in our country have been assessed. Based on this several model systems of different type and construction were selected. For some of the irrigation fields, possible technical solutions concerning their completion, reconstruction and modernization have been analyzed.

In this paper an algorithm for creating an atlas-based finite element heart model for cardiac simulation is described. This model is used to simulate the propagation of electrical impulses of the heart. An important feature of this model is that it contains conductive paths and fibrous tissue, which makes it possible to make more realistic calculations of the propagation of electrical signals. The model created from anatomical segments of the heart surface is defined by a polygonal mesh. The algorithm presented in the article offers a means to create models of various accuracy.

The steam distillation is the most frequently method for production essential oil from fresh medicinal and aromatic plants. This paper compares an existing with an innovative solution of the substance flow system which is used for production essential oils from the biomass of lavender, juniper, immortelle, chamomile, etc. In order to improve the effectiveness of the distillation process as well as the quality of extracted essential oils, most often used substance flow system was reconstructed. The existing solution of distillation equipment was improved with two innovations. The first one refers to the supply of steam from upper side into the distillation unit, and the second is the technical solution of the condenser. The new distillation equipment was produced in domestic company, and analysis of produced essential oil from immortelle was compared with oil produced with classic distillation method. The analysis showed the improvement of the quality of the essential oil produced with new distillation unit.
