Bovine ephemeral fever (or 3-day sickness) is an acute febrile illness of cattle and water buffaloes. Caused by an arthropod-borne rhabdovirus, bovine ephemeral fever virus (BEFV), the disease occurs seasonally over a vast expanse of the globe encompassing much of Africa, the Middle East, Asia and Australia. Although mortality rates are typically low, infection prevalence and morbidity rates during outbreaks are often very high, causing serious economic impacts through loss of milk production, poor cattle condition at sale and loss of traction power at harvest. There are also significant impacts on trade to regions in which the disease does not occur, including the Americas and most of Europe. In recent years, unusually severe outbreaks of bovine ephemeral fever have been reported from several regions in Asia and the Middle East, with mortality rates through disease or culling in excess of 10–20%.

The fact that agriculture has been developing since ancient times is the basis for creating new varieties. Today, the demand for the food problem is increasing. That's why the study of the effect of sowing seeds in optimal terms to increase the yield of Asr variety of winter wheat has been highlighted.

The demand for food in our country is increasing. Based on this, it is recommended to carry winter wheat varieties to open fields in accordance with the planting itself. Winter wheat is more resistant to winter frosts than other crops. When sowing wheat seeds, it is necessary to follow agrotechnical measures and terms.

This paper proposes an algorithm for constructing expert systems (ES) in comparison with a physician's decision to determine epilepsy in children. The main characteristics of electroencephalography are defined. A decision tree method (DTM), which provides a therapeutic and diagnostic process, is proposed. A method of medical data analysis is proposed, which makes it possible to determine the type of epilepsy in children. The main provisions of a medical expert system for diagnosing epilepsy, based on the decision tree method, are developed. The specialist performs a visual analysis of the EEG and concludes that the EEG is normal. A brief note is given on the analysis of medical data, which allows to determine the type of epilepsy in children. The aim of this study is to develop expert systems for the diagnosis of epilepsy, as well as to create new methods based on the solution tree. The proposed algorithmic and software for determining epilepsy in children with reliability and efficiency of 92 % determines the type of the disease. In a study of 370 patients, we received 186 patients (the rest are healthy), in which the diagnoses coincided with the doctor's diagnoses. The software was created in the Python language, and a Dataset of patients with their disease parameters was created.

Vinyl chloride, CH2=CHCl — monochloroethylene, colorless gas. Molar mass 62.50; boiling point — 13.8°, melting point — 158.4°, density 983 kg/m3 (at 15°). Well soluble in chloroform, dichloroethane and ether, poorly soluble in water. Vinyl chloride is obtained by withdrawing one molecule of hydrogen halide from dihalide derivatives and attaching one molecule of hydrogen halide to acetylene hydrocarbons. Vinyl chloride is mainly used as a raw material in the production of polyvinyl chloride, various copolymers, vinylidene chloride and methyl chloroform.
