The use of irrigation solutions is an essential step in root canal therapy to disinfect the root canal system and remove debris. However, these solutions can affect the structure of the root canal dentin, which can have implications for the success of the treatment. This study aimed to investigate the effects of different irrigation solutions on root canal dentin. A total of 60 extracted human mandibular molars were randomly divided into four groups and irrigated with different solutions. The effects of the irrigation solutions on the root canal dentin were evaluated using scanning electron microscopy and energy-dispersive X-ray spectroscopy. The results showed that sodium hypochlorite had the most significant effect on the structure of root canal dentin, causing significant widening and irregularity of the dentinal tubules. Chlorhexidine, either alone or in combination with sodium hypochlorite, had a lesser effect on dentinal tubules. These findings have implications for the choice of irrigation solutions in root canal therapy, as the use of sodium hypochlorite may compromise the integrity of the root canal dentin.

Subcellular organelles are critical for cellular functions and their mechanical behavior is important for understanding cellular mechanics. Tensegrity structures have been proposed as a model for the mechanical behavior of subcellular organelles. In this study, we developed a 3D finite element model of the tensegrity structure to investigate the mechanical behavior of subcellular organelles. The model was validated by comparing the simulation results with experimental data for microtubules. Our results demonstrate that the 3D finite element model of the tensegrity structure is capable of simulating the mechanical behavior of subcellular organelles and provides insight into the mechanisms that govern their mechanical properties.

Balancing on visco-elastic surfaces is a challenging task for legged robots, requiring effective reactive balance control strategies to maintain stability. In this paper, we present a comparative study of three reactive control approaches: proportional-derivative (PD) control, proportional-integral-derivative (PID) control, and sliding mode control, for legged robots under visco-elastic contacts. A simulation framework was developed to test the performance of the three control strategies on a six-legged robot model, subject to visco-elastic contacts of varying stiffness and damping coefficients. The results show that all three control strategies were effective in stabilizing the robot, but the PID control strategy performed better in terms of reducing the settling time and overshoot. PD and sliding mode control strategies were more robust to changes in contact conditions and exhibited better performance in some cases. The findings provide insights into the design and implementation of reactive balance control strategies for legged robots under visco-elastic contacts.

It is important to provide the population with clean drinking water. Drinking water must meet the requirements of special state standards and is a constant focus of health care institutions. The state standard requires the organization of sanitary protection zones of water sources and main water intake facilities.

Psychophysical, neurological and sociological dualisms between the sexes are the main causes of an incompatible male-female unions-communities (friendship, romantic relationship, marriage or extramarital community). As long as the woman's body (it's a different mechanism for men) does not get used to the "hormones and substances of love": phenyl ethylamine, nor ephedrine, dopamine, oxytocin, endorphin, etc. a woman does not initiate a struggle to free herself from a position of inferiority in relation to a man (emancipation), because the community between a man and a woman is dominated by love, which abstracts the inherited, constructed and socially accepted differences between the sexes. The emancipation of a woman within the formed man-woman community begins with the adaptation of the organism to the "hormones and substances of love", which is time-specific and determined by the personal character, temperament and structure of the formed community. The emancipation of women in community with men is initiated and then developed by the dualism of psychophysical, neurological, and then constructed sociological differences between the sexes. In the paper, the genesis of dualisms between the sexes, their social adoption, with corrections resulting from the process of women's emancipation, as well as the consequences suffered by incompatible formed male-female communities in today's contemporary industrial-technological society, are presented in a simplified manner.

In this article the experiences of European countries in developing sustainable public transport is learnt and matched to different Asian developing countries such as Uzbekistan. The most initial steps to develop preliable and attractive public transport are inspected and steps of approach regarding how we should develop our public transport are mentioned with details in this paper.

This article examines the results of a number of reforms carried out by the Republic of Uzbekistan from the moment of independence to the present day to protect human rights, freedoms and legitimate interests, especially important steps taken in recent years towards the creation of a state that glorifies human value, and these reforms show that in Zamir they are becoming important it is the interests of a person, respect for human values, attitude towards a person. declared.

It also highlights some of the problems that existed in the field of social security until the coming years, and information about the reforms carried out after 2017 to solve these problems.

In this article, as a result of a logical analysis of the interior decoration of the dome of the Taj Mahal Hotel, our scientific hypothesis that this astronomical image, the image of the universe is a simple model of the universe composed of 9 layers, and that the universe is a system of galaxies located on the intersecting lines of the grid, i.e. a metagalaxy, is determined to be composed of internal and general gravitational attraction. stated.

The article discusses the use of multimedia technologies in vocational education, allowing for the design, implementation of content, methods, and forms of education effectively with the task of achieving the goals of the educational process, which involve the use of hardware and software multimedia and interactive software. Multimedia technologies are equipped with educational resources, which are considered one of the most powerful, since their use ensures the formation of the student, as well as the manifestation of his core competencies. The use of multimedia technologies in the learning process is associated with its enrichment due to the effectiveness of this application, as well as the susceptibility of students based on sensory components. Multimedia technologies are a promising direction in the learning process.

Of course, promoting the sale and use of electric transport vehicles in Uzbekistan is one of the important issues. As mentioned above, this issue is gaining importance in the world as well. Electric transport vehicles are at the forefront of new trends in developing ecological safety and transportation. Uzbekistan also aims to increase the use of these special transport vehicles and accelerate their development. Therefore, the government of Uzbekistan has decided to adopt a state policy of "green energy" and new investments are being made in this direction. To promote the widespread use of electric transport vehicles, several ways are available such as reducing their prices, corporate loans, cooperation and research, independent energy use, and infrastructure development. All of these are essential for the development and promotion of electric transport vehicles, which is crucial for solving ecological safety issues and further developing the transportation sector.
