The choice of the motor may be based on the average power or average current. At the outset, this method seems to be applicable. It has, however, a disadvantage in that it does not consider the variation of losses. The motor chosen will be smaller for the load cycle, and of insufficient capacity. This may have increased temperature due to overloads, where the losses increase. This happens if the load fluctuations are considerable. The method may give a satisfactory motor if the load fluctuations are relatively small. There are two types of Continuous Duty Motor — continuous duty at constant load and continuous duty with variable load cycle. In the former the load torque remains constant for a sufficiently longer period corresponding normally to a multiple of time constant of the drive motor. The drive motor is therefore loaded for a sufficient amount of time continuously, till it attains thermal equilibrium.
This scientific article analyzes the importance of notarial activity in protecting the rights of individuals and legal entities, and separately highlights the features of the use of blockchain technology in the work of notaries, which is a promising direction for improving notarial activity and practice. The relevance of the study lies in the fact that the issues of digitalization and the use of blockchain technologies in notarial practice are currently poorly studied, which leads to increased interest in these issues. Constant scientific developments in this direction allow notaries to enrich their knowledge, develop skills and competencies, which is the basis for improving the quality and professionalism in the provision of notarial services. The purpose of the scientific article is the need to consider the aspects and features of notarial activity, and determine its impact on the protection of the rights and interests of various subjects of civil legal relations. The research methodology in a scientific article consists of using such methods of cognition as the dialectical method, analysis, synthesis, induction, deduction, generalization, modeling, forecasting. The results of the study are developed scientific and theoretical proposals on improving notarial activities, taking into account the use of digital technologies. Specifically, notarial actions were highlighted aimed at protecting the rights of individuals and legal entities for whom contacting a notary is a constant necessity. The obvious conclusion was that the study of notarial activities contributes to the search for new methods, technologies and approaches that can improve processes in this area, simplify procedures and increase the level of confidence in notarial acts.
This article is devoted to the application of new teaching methods in medical universities in the context of distance learning. The events of 2019 - 2020 related to the COVID-19 pandemic turned out to be not only a test for the economy of our country and its healthcare system, but also a kind of stress test for the education system. The system of higher medical education is no exception, which, in comparison with universities in other areas, faced additional difficulties. The quarantine conditions necessary to preserve the health and life of the population touched and could not but affect the medical education system. Spring semester of 2020 from March 18, in connection with measures to prevent the import and spread of a new coronavirus infection (COVID-19), training at universities in Uzbekistan was transferred to a distance format. During this period, a voluntary anonymous survey of 170 students was conducted. The distance form of the educational process is based on the principle of independent learning, in which students are distant from the teacher both in space and in time. At the same time, students have a constant opportunity to maintain constant information contact with teachers using modern Internet technologies. New forms of education are in demand at this time, as they form an extraordinary and effective approach to teaching in the subject of pharmacology. From the results of the survey it follows that the attitude to the possible use of elements of the distance learning system increases the independent training of students in pharmacology by 60 -70%. Distance learning in medical universities can be used as an alternative to traditional education in a pandemic.
Dielectric properties play a crucial role in the performance of micro-composites used in various applications such as flexible electronics and energy storage devices. This study focuses on investigating the dielectric properties of micro-composites based on acrylic coated conducting carbon particles embedded in a silicone elastomer matrix. The acrylic coating enhances the dispersion and compatibility of the conducting carbon particles within the silicone elastomer, ensuring uniform distribution throughout the matrix. The dielectric properties, including the dielectric constant and loss tangent, are characterized over a range of frequencies and temperatures. The results reveal the tunability of the dielectric constant by adjusting the filler loading and coating thickness, enabling tailored electrical properties of the micro-composites. The low loss tangent indicates minimal energy dissipation and suggests the suitability of these micro-composites for applications requiring efficient dielectric materials.

The improved engine driven sorghum threshing machine was designed and produced at Fedis agricultural research center with the objectives of solving the critical threshing and cleaning problems of sorghum produce the farmers’ and subsequently, to reduce the drudgery of the farmers’, grain loss and cost of threshing, in comparison with traditional methods of manual threshing by using wood log. The developed machine was tested in east Hararghe Zone, Haramaya district, Horo Kebele. The variables considered includes two sorghum varieties (muria and fandisha), three levels of cylinder speed (500,700 and 900 rpm), three position of cylinder-concave clearances (13, 18 and 23 mm) and three feed rates of the un-threshed sorghum head (10 kg/min, 15 kg/min and 20 kg/min). The experimental design was split-split plot design with three replications. The result obtained indicated 87.28-95.30% threshing efficiency, 7-10 qt/h output capacity and 74%-88% cleaning efficiency at constant grain moisture contents of 15-17% for both varieties.
It's critical to perform a preliminary inquiry if a dismembered body is discovered. The first stage of a murder inquiry is primarily concerned with determining whether the murder was premeditated or unintentional. The first situation does not necessitate the use of a different research technique; however, the second situation does necessitate the use of a separate investigation methodology in this regard.
The initial stage of the murder investigation requires the implementation of preliminary investigative actions and operational-search measures. In this case, the concept of initial investigative actions is a forensic concept, while urgent investigative actions are both forensic and criminal-procedural concepts. These two concepts - initial and urgent - can be both proportional and incompatible [1, p. 16]. Article 14 of the Law of the Republic of Uzbekistan dated December 25, 2012 "On operational search activities" provides for 16 types of operational search activities.
Optimization of diagnostics and schemes of pathogenetic intensive therapy of surgical sepsis in children based on clinical and laboratory criteria and bacteriological monitoring.Materials and methods: The research period is 2018-2020. The object of the study (n=73) – children with surgical pathology (widespread peritonitis, bacterial destruction of the lungs, post-traumatic brain hematomas, abdominal trauma, etc.). Research methods: microbiological monitoring to determine the sensitivity of the micro-organism to antibiotics was carried out before and at the stages of treatment (sputum, urine, wound, bron-choalveolar lavage, tracheal aspirate, blood, contents from drainages, wound surface). Determination of the sensitivity of the isolated strains to antibiotics was carried out by the disk-diffusion method. To determine predictors of sepsis in surgical patients, clinical (mean arterial pressure (mAP), heart rate (HR), respiratory rate (RR), SpO 2 , etc. and laboratory parameters on days 1–2 (up to 48 hours) of sepsis identification, days 4 and 8 of intensive therapy. Procalcitonin was determined by immuno-fluorescence on a Triage® MeterPro analyzer (Biosite Diagnostics, USA). Blood gases and electrolytes were analyzed using a Stat Profile CCX analyzer (Nova Biomedical, USA). Results: studies have shown the effectiveness of complex intensive care in 86.3 % of cases. Mortality was found in 13.7 % of cases. Patients with severe surgical pathology died: widespread peritonitis, severe TBI + coma with irreversible neurological disorders, urosepsis against the background of chronic renal failure, after repeated surgical interventions, due to the development of refractory septic shock (SS).
Conclusions. Early diagnosis of sepsis, rational early ABT under the control of microbiological monitoring, non-aggressive infusion therapy with early prescription of vasopressors (SS) with constant monitoring of the child's main life support organs contribute to an improvement in sepsis outcomes and a decrease in mortality
This paper analyzes the psycho physiological changes that occur when exam stress affects healthy
and mentally retarded schoolchildren aged 14-16 years. Psychological and cognitive indicators were
studied. The experiments were conducted in three stages: on a normal school day (control), before
the exam, and after the exam. The analysis of the obtained data showed that during the exam,
healthy schoolchildren experience psycho physiological changes, i.e. the level of stress indicators
(anxiety) increases and cognitive indicators weaken. After the exam, there was a tendency for these
indicators to return to the control level. In contrast to healthy children, mentally retarded
schoolchildren had a high level of anxiety index during the control examination, and their cognitive
indicators were 35% lower than normal. During the examination period, these indicators remained at
a relatively constant level. A comparative analysis of the data showed that depending on the level of
mental development of students, exam stress leads to stress in the psycho-emotional state of
students and this can have a serious impact on their health.
The oral cavity plays an important role in perceiving the environment, and its condition is an informative indicator that reflects changes in the state of the human body that is affected by environmental factors. Epoxy resins were first used in commercial trade in 1946 and today are used in various sectors of the national economy, including shipbuilding, chemical, automotive, road, construction, aviation, furniture, agriculture and household industries. [2, 3].
The study of dental disease in individuals exposed to harmful industrial chemicals shows that in many cases a general trend in the development of pathological processes in the oral cavity is observed. Dental caries and its complications, inflammatory diseases, as well as periodontal injury have an etiological connection with the violation of the oral microbiocenosis. The constant exposure of chemical compounds to the oral mucosa at low concentrations in the air can contribute to changes in saliva composition, microbiocenosis structure, which ultimately leads to a secondary deterioration of the hygienic condition of the oral cavity.
In today’s world, where the borders of different countries are becoming easier to overcome, especially for professionals in the medical field, importance of English is significantly increasing. Globalization and accelerated exchange of information require knowledge of the language of international communication and, in particular, its special features and the use of terminology in the medical professions. Consequently, it becomes urgently necessary to acquire reading skills and a good understanding of the medical literature in the English language for progressing to the level required for communication with colleagues form the USA, the UK, Australia, Israel and other countries known for their significant achievements in the development of medicine. Why should a doctor know English? First of all, it may seem that the doctor’s knowledge of English is not the key aspect in professional growth. In fact, if you aim at the constant improvement of skills and want to work in a prestigious clinic, and even more so, to cooperate with your foreign colleagues, you must know English. Let’s see how the knowledge of English helps a doctor.
Creating new job vacancies is a natural process of economic development. Continuous improvement of production, the constant implementation of scientific and technological innovations in practice
in the form of proactive reproduction, the creation of new job vacancies through advanced structural transformations are being carried out. Without creating new job vacancies, the optimal employment structure will not be formed, and labor productivity will not increase. With the transition of Uzbekistan to a market economy, the
conditions for creating new job vacancies have changed dramatically. The emergence of diverse forms of ownership, expansion and modernization of existing enterprises have created jobs that meet modern requirements. The results of such development give results in the regions.
