Compared to energy-saving lamps, LED lamps have become a trend.

Computer vision as a scientific discipline refers to the theories and technologies for creating artificial systems that receive information from an image. Despite the fact that this discipline is quite young, its results have penetrated almost all areas of life. Computer vision is closely related to other practical fields like image processing, the input of which is two-dimensional images obtained from a camera or artificially created. This form of image transformation is aimed at noise suppression, filtering, color correction and image analysis, which allows you to directly obtain specific information from the processed image. This information may include searching for objects, keypoints, segments, and annexes;

The practical use of songs in ELT is not a new technique, however music, songs are considered as a powerful tool in teaching a foreign language. It is known that the more sense organs are involved in the educational process, the more effective music in the lesson inspires, relaxes, captivates, and adjusts to a subtle but strong wave of perception. In addition, music develops memory and thinking as well.  In this article, we will discuss the mechanisms of the influence of music, songs on the motivation of students, improving the quality of mastering new educational material, developing speech skills, creative and cognitive abilities, as well as reducing emotional tension in the process of teaching a foreign language.

For almost a century, many have considered lipids as the sine qua non of atherosclerosis. However, in 1856 Rudolf Virchow introduced a theory that inflammation is the driving force of atherogenesis. Recruitment of blood leukocytes to the injured vascular endothelium characterizes the initiation and progression of atherosclerosis and involves many inflammatory mediators, modulated by cells of both innate and adaptive immunity. The pro-inflammatory cytokine, interferon (IFN)-γ derived from T cells, is vital for both innate and adaptive immunity and is also expressed at high levels in atherosclerotic lesions. As such, IFN-γ plays a crucial role in the pathology of atherosclerosis through activation of signal transducer and activator of transcription STAT1.Our study indeed provides evidence that in HMECs STAT1 coordinates a platform for cross-talk between IFNγ and TLR4, and identifies a STAT1-dependent gene signature that reflects a pro-atherogenic state in coronary artery disease (CAD) and carotid atherosclerosis. Taken together, our data indicate that in the presence of appropriate stimuli, HMECs are highly responsive and consistently express Cxcl9. HMECs may therefore provide a better model for in vitro studies of atherosclerosis.

This article examines the metric system of arud, created by the largest medieval Arab philologist Khalil ibn Ahmad, one of the founders of the famous Basrii philological school.

But Makanin's prose remains a part of the literary process, the literary period of study, that is, it needs scientific understanding. The organization of the artistic space in the narrative is carried out through images, they are the most significant part of the novel space.

The subject of this research is the concept of reduction in the logic and methodology of science. On the one hand, reduction is understood as a relationship between a term and its defining expression within a scientific theory, on the other hand, as a relationship between two theories. Since the expansion of the theory occurs due to the introduction of new terms into its vocabulary with the help of nominal definitions, reduction is an operation opposite to the definition: due to reduction, terms are removed from the dictionary of the theory. Moreover, the theory itself is defined in accordance with the set-theoretic approach as a class of sentences that are closed with respect to derivability. The novelty of the research lies in the fact that it examines the semantic and epistemological aspects of the formal definition of reduction. In particular, the explication of the reduction relation between the two theories is based on the concept of functional equivalence of theories. It has been established that the list of basic terms of the theory can only be specified conventionally. All terms introduced with the help of nominal definitions turn out to be reducible. Consequently, a distinctive feature of a theoretical term is the possibility of its reduction.

Fake re-energize of springs from fleeting water or treated waste water has become an advantageous answer that permits recreating long haul stores of springs, including those influenced by over-abuse. Through working highlighted purposes behind homegrown, horticultural and modern Pliocene-Quaternary the snare of Saiss plain Experiences a diminishing in groundwater saves and the meaning of water in semi-parched zones to bone-dry, it was important to cure this condition by the development of underground dams and slope lakes.

Despite predictions that the fuel industry will supposedly be out of business in the near future, experts predict that minerals such as oil and gas will be around for a long time and will not go down fast yet. However, a paradigm shift in the energy complex is bound to happen - for example, blue fuel (aka natural gas) is expected to become several times more popular with the public than black gold (oil), which currently has a significant influence on the global economy. Many enhanced oil recovery methods include the use of microbial surfactants and biopolymers. These compounds can be obtained by exploiting the potential properties of microorganisms to produce them. The following article focuses on effective oil recovery methods using bio products.

Human health is one of the most important issues for every period of society’s development. Indeed, the level of health and literacy of the population living in the region determine the state of development of any country. These two indicators reflect the role of states in the world community and their socio-economic potential. Each season is distinguished in terms of its natural features by the outbreak of certain diseases or the temporary cessation of some of their vital activities. In particular, due to a sharp drop in temperature in winter, infectious diseases are reduced, while in humans, due to sudden changes in temperature, colds increase. This, in turn, leads to the opposite.
