The history of the study of fossil vertebrates of the Cenozoic era (from the Late Miocene to the Holocene) in the territory of Western Kazakhstan dates back to the XVIII century. Since then, dozens of their locations have been discovered, where valuable paleontological material, including skeletons and skulls, has been collected. The study of the Cretaceous reptiles of Kazakhstan began at the end of the XIX century. Ichthyosaurs and plesiosaurs are characteristic of the entire Early Cretaceous and Cenomanian, which is associated with the largest number of finds. Terrestrial reptiles-archosaurs (mainly dinosaurs, less often crocodiles and pterosaurs) and turtles - are known from the Neocomian to the Senon inclusive, but predominate in the first half of the Late Cretaceous. The history of the study of large mammals of the Cenozoic era and reptiles of the Mesozoic era on the territory of Kazakhstan, from the very first works of the XVIII century to the present time, is considered.

The article discusses the conditions for the formation of oil and gas complexes (oil and gas play) in Aryskum trough. Geological and geophysical data of deep geological structure confirm that formation of sedimentary basin and lithological-stratigraphic complexes, oil and gas complexes (oil and gas plays) of Southern Torgay was influenced by the rift-induced geodynamic regime of oil and gas formation. The stages of rifting are divided: pre – rift, initial – formation (early Jurassic), middle – subsidence (early-middle jurassic) and final (late jurassic), which are associated with the formation of jurassic productive horizons. The Cretaceous productive horizons were formed during the epirift stage. The rift mode of oil and gas formation assumes high warming of the subsurface and conditions for the migration and accumulation of hydrocarbons and confirms the prospects for searching for hydrocarbon traps in the Aryskum trough.

The article presents the issues of monitoring and analysis of agricultural land using satellite imagery data. Images from the European Space Agency's Sentinel-2 satellite were used as the main research material. This satellite provides optical data that is used for many areas, such as monitoring for floods, landslides, fires, agricultural crops, etc. The area of the Northern Economic Zone of Kazakhstan, the mouth of the Yessil River, was used as the object of the study. The vegetation index NDVI (Normalized Difference Vegetation Index) was used for monitoring, and the basic principles of its application were explained. The analysis of the obtained result is presented and the diagrams show changes in the vegetation background of the studied territory. Special recommendations were given for further improvement of research methods and its effectiveness was justified.

The article implicates with aspects of geodynamic monitoring at hydrocarbon fields. The main factors of geodynamic risk - natural and technogenic are given. The foreign and domestic experience in conducting geodynamic research is briefly presented, also illustrated the forms of manifestation of natural and technogenic geodynamic processes. Information about geodynamic events and deformation processes in the developed oil and gas fields is generalized. The principles of creating geodynamic polygons and technologies for conducting geodynamic monitoring in hydrocarbon fields are considered, including equipment and basic monitoring methods. Work on the creation of a geodynamic polygon and carrying out geodynamic monitoring on it should consist of several main interrelated stages. Thus, in the conclusion, the most optimal and effective sequence of geodynamic monitoring at the developed hydrocarbon fields is formulated.

This article introduces a new high-performance LED driver. The developed version of the LED driver is based on an active AC-DC converter with a reverse-pass topology. A special feature of the proposed scheme is the use of a current/ voltage stabilizer on the primary side based on the FL7733A microcontroller and a passive stabilizer on the secondary side. The method of calculating the current values of the current value is presented. According to the proposed scheme, an experimental sample of the LED driver was designed and assembled. Functional tests were carried out, which show a qualitative advantage over the standard LED driver circuit. Temperature tests were carried out, and it is clear that the driver elements do not experience excessive temperature loads and operate within normal temperature limits.

In this article the integro-differential equations of own vibrations of a viscoelastic ribbed truncated conical shell are obtained on the basis of the Lagrange variational equation. Using the finite element method, a method for solving and an algorithm for the equations of own vibrations of a viscoelastic ribbed truncated conical shell with hinged and freely supported edges has been developed. The problem is reduced to solving homogeneous algebraic equations with large-order complex coefficients. For a solution to exist, the basic determinant of a system of algebraic equations must be equal to zero. From this condition, we obtain the frequency equation with complex output parameters. Complex roots of the frequency equation are determined by the Muller’s method, at each iteration of the Muller’s method, the Gauss method with the selection of the main element is applied. The study of own vibrations of viscoelastic panels of truncated conical shells is carried out and some characteristic features are revealed. With an increase in the number of edges, respectively, the real and imaginary parts of the own frequencies increase.

Unlike rigidly coupled parallel robots, parallel cable robots (PCR) are driven by flexible cables rather than rigid links to control the position and orientation of the working body. PCRs have the advantages of parallel robots over conventional robots, including a higher load-to-weight ratio. PCR have lower inertial characteristics and a higher payload-to-weight ratio, which provides high speed and acceleration of the working body. Due to the flexibility of the ropes, PCRs can be used to solve complex tasks with a large working area of ​​service. This article provides an overview of some types of parallel cable robots developed in the world. An overview of works on the design of the PCR, structure, kinematics and dynamics, control and trajectory planning is shown. The conducted review of cable parallel robots will be useful for students and doctoral students working in the field of research of fundamentally new robots.
