This paper examines the selected constructions of piston for aircraft CI engines and discusses tendencies in a development of piston designs. The paper addresses the question of using new materials and coatings to improve quality of pistons and the study of heat transfer and methods to absorb heat from a piston by means of cooling ducts. The selected materials were examined in terms of their advantages and drawbacks. The paper discusses different shapes of piston heads and their impact on combustion as well as indicates other factors behind parameters of combustion and toxic emission like injector shape types, lubrication types and clearances in the combustion chamber.

Lateral Flow Tests

Analytical devices for point-of-care diagnoses are highly desired and would improve quality of life when first diagnoses are made early and pathologies are recognized soon. Lateral flow tests (LFTs) are such tools that can be easily performed without specific equipment, skills, or experiences. This review is focused on the use of LFT in point-of-care diagnoses. The principle of the assay is explained, and new materials like nanoparticles for labeling, new recognition molecules for interaction with an analyte, and new additional instrumentation like signal scaling by a smartphone camera are described and discussed. Advantages of the LFT devices as well as their limitations are described and discussed here considering actual papers that are properly cited.

Oriented Approach

The article describes experience of creating and implementing information-managing educational environment at university. The model of creating information-managing educational environment of university with elements of artificial intelligence and indicative management is described. This environment contributes to improve quality of training and management of educational processes and resources. The stages of creating and implementing information-managing educational environment are considered systemically, as continuous process focused on a consumer. The inhibitory and facilitating conditions for introduction of the model at university are described. To provide subject-oriented approach to the use of information resources of environment, recommended clusters of information subsystems for each category of users are described.Practically implemented scientific and methodological recommendations for subjects of educational process to overcome resistance to innovations introduced in educational organizations are proposed.Features of adaptation of the developed information-managing educational environment for schools are presented.

Special Library

The special library acts as the cultural and educational center for visually impaired people, and as the center for continuing education. The multifunctional performance of the library is substantiated. The joint projects accomplished in cooperation with theatres and museums and aimed at integrating the visually impaired people into the society are described. Advanced training projects for the library professionals accomplished in 2018 are discussed.
