The adoption of Law of Ukraine "On Higher Education" (2014) involves the increase in students' selflearning activity part in the curriculum. Therefore the self-learning activities' arrangement in a way augmenting the result quality becomes a top priority task. This research objective consists in elaborating the scenario for organization of the students' qualitative self-study, based on blended learning models. The author analyzes four blended learning models: the rotation model, flex-model, self-blend model and online driver model, and gives examples of their use. It is shown that first two models are the most suitable for full-time students. A general scenario for the use of blended learning models is described. Although the use of blended learning models causes several difficulties, it also essentially contributes into students' selfstudy monitoring and control support. [ABSTRACT FROM AUTHOR]

It was shown that our visual system and brain are able to initiate the appearance of images of pictures in an imaginary plane simultaneously behind and before their real plane and continuously watch their independent displacement.

However, under some conditions, the eye movement and the shift of the gaze to perspective can be accomplished by non-forced methods, without any active interference of our consciousness.

A unified photometric method for determination of nitrates and nitrites in multicomponent salting mixtures containing sodium nitrate and nitrite, chlorides, phosphates, polyphosphates, ascorbic acid, or ascorbates, antioxidants, organic acids, vegetative and animal proteins, carbohydrates is proposed. With use of the developed method, content of nitrates and nitrites in a number of salting mixtures meat production was estimated.
