Continuous transport machines, in particular belt conveyors, are used in a wide variety of industries. Such machines are especially effective when used in mechanical engineering, in warehouses, and in the logistics system. In the process of intensifying production, a number of requirements are placed on conveyors in terms of their productivity and the accuracy of cargo positioning. These requirements can only be achieved by adjusting the speed of the electromechanical conveyor system. In turn, the regulation will necessarily cause uneven movement of the conveyor belt and oscillation of the load relative to its equilibrium position. Due to wear and tear of technological equipment, as well as changes in loading patterns, the conveyor is a significantly unstable object, the properties of which change significantly over time. In addition, the electromechanical system of the conveyor is influenced by external disturbances, the nature of which varies from smooth and continuous to sharp and intermittent. All this allows us to conclude that the electromechanical belt conveyor system, from a control point of view, is a non-stationary object. On the other hand, operating experience shows that we get the greatest effect from the operation of cargo transportation systems when regulating the speed of the belt conveyor. For example, energy savings of up to 30%, while increasing the stability of conveyor systems by 10%. Therefore, today the urgent task is to develop a model of an adaptive automatic control system for EMC conveyor belts, taking into account the influence of external disturbing factors, which will limit load fluctuations in combination with high productivity. The article uses materials from a project to automate the conveyor belt system used for transporting air conditioners and refrigerators produced at the enterprises of ARTEL, Tashkent

The analysis of human papillomavirus disease provided a theoretical analysis of local and foreign literature. The literature review analyzed the etiology and classification of Human Papillomavirus disease and the assortment of drugs used. A theoretical analysis of medicines and treatments used in human papillomavirus disease has been carried out. As a result of the gradual increase in human papillomavirus disease worldwide, including in the world, treatments are under way based on pharmacotherapy groups of drugs used therein. On this basis, there has been an opportunity to analyze the drugs used in Human Papillomavirus disease for patients with Human papillomavirus disease in Uzbekistan and medical prevention facilities. The etiology and classification of human papillomavirus disease, the epidemiology of human papillomavirus disease, and the drugs and treatments used therein have been theoretically explained.

The results of the conducted screening to study the risk factors of cerebrovascular diseases and stroke are presented. A special questionnaire was used to determine the degree of risk of development, which included the Fedin ambulatory scale, Mini KOH test, as well as blood cholesterol and sugar, blood pressure, body mass index, and carotid auscultation. Low risk of CVD and stroke was found in 48%, intermediate risk in 36%, and high risk in 16% of the subjects

Arteriovenous malformation (AVM) is a congenital abnormality of the blood vessels in the brain, consisting of clusters of various shapes and sizes formed by the disorderly interweaving of pathological vessels. Typical AVMs have three main components: feeding arteries (AVM afferents), a cluster of altered vessels (the core of the malformation), and draining veins (AVM efferents). AVMs usually lack a capillary network, resulting in direct shunting of blood from arterial vessels into the superficial and deep veins of the brain. This vascular abnormality of the brain occurs in 0.01% of the population, more commonly in men, with peak manifestation occurring between the ages of 20 and 40. AVMs are diagnosed based on magnetic resonance imaging (MRI), but selective cerebral angiography is considered the gold standard. Vascular development occurs in two stages: vasculogenesis (the formation of blood vessels de novo in embryogenesis) and angiogenesis. Most genes and genetic risk factors play a role in the development of vasculogenesis, angiogenesis, and vascular remodeling.

The results of a screening conducted to study the risk factors for the development of cerebrovascular diseases and stroke are presented. When identifying the degree of risk of development, a special questionnaire was used, which included амбулаторная шкала the Fedin outpatient scale, the Mini COG test, and also took into account cholesterol and blood sugar indicators, blood pressure, body mass index, and carotid artery auscultation. A low risk of developing CVD and stroke was found in 48 %, moderate - in 36%, and high-in 16 % of the examined patients.

"Febrile convulsions" is a term used to describe the occurrence of convulsions in children with an increase in body temperature to 38° C and above. This can occur in the age group from six months to 5 years, most often from one to one and a half years. In most cases, infections are responsible for the development of this symptom, less often it is observed as a post-vaccination reaction (after the introduction of vaccines). In general, febrile seizures are not dangerous. But it is important to show the child to the doctor to make sure that the symptom is caused by fever, and not by other diseases.

There is a widespread belief that the literature on urinary incontinence is very large, and the problem is thoroughly studied. But this opinion is completely unfounded, there are few serious literary sources, and even fewer scientific ideas that guided the authors [1,2, 5,6].
