It is important to gain a better understanding regarding the effect of frequent drought stress on biochemical and physiological processes in plants as well as on the plant population and community in ecosystem. One method of early detection and monitoring of water stress is by measuring the diameter changes of the stem using dendrometers. They can be used to determine not only the annual thickness growth, but also the distribution of the growth and the rate of expansion and shrinkage of the wood and bark during th...

Extensive research, conducted by Kazakhstani specialists in Earth sciences, resulted in accumulation of a big amount of information. Hydrogeological data are scattered and unsystematized, and it makes their processing and analysis very difficult. Therefore, it is necessary to create a unified information base, containing profile hydrogeological information and data from the related areas of knowledge, which will help to solve scientific and production tasks efficiently. Informational and analytic systems are devel...

The article deals with the analysis of the possibility of observing body and clothes surface temperatures changes of large groups of people using thermography. Additional heat gains from people play a significant role in buildings where many people stay simultaneously. In those buildings, there is increased emission of heat from people, which has a significant impact on the microclimate of those buildings. This applies especially to sacral buildings, as well as other types of buildings where many people are inside...

The microclimate of the urban environment is influenced by urban development, road surface, distribution of green areas. The city, especially with a highly developed industry, pollutes the atmosphere above itself, increases its turbidity and thereby reduces the influx of solar radiation. Such changes in the microclimate of the urban environment often occur as a result of changes in urban development, artificial changes in the relief, and the cutting down of forest plantations. Due to changes in the urban environme...

The main tasks and provisions of multiscale image processing of nanostructures are formulated, the feature of which is the use of the concepts of heredity and variability of characters. Heredity refers to the process of preserving traits on a sequence of images of a nanostructure as the scale of observation changes. Under variability refers to the process of loss of signs or the emergence of new signs on a multiscale sequence of images. It is obvious that images of nanostructures on scales at which there is a shar...
