And Behavior

Petri nets have structure and behavior properties, it is convenient to analyze some complex system based on its mathematical analysis methods. Online top-up system is an open network system. The modeling method of this system based on general Petri net has some limitations. A new modeling method based on open Petri net to study online top-up system is proposed, and analyze the open Petri net model by T-invariant. This method laid a foundation for the study of open online top-up system.

The article presents the results of the research concerning the pharmacotherapy of patients with chronic pancreatitis with comorbidity from the pharmacological view. During the study pharmacological approach to the problem of comorbidity among patients with chronic pancreatitis was analyzed. A survey among doctors and pharmacists was used during the research along with normative and legal, documentary, retrospective, bibliographic, systemic, forensic-pharmaceutical, sociological (questionnaire survey), comparative, graphic, mathematical analysis methods. The most common comorbid diseases that patients suffer from alongside with chronic pancreatitis were highlighted. Authors came to conclusion, that development of safe and affordable pharmaceutical therapy for patients with chronic pancreatitis and comorbidity is very important.

Abstract. A study of the regularity of precipitation distribution at the airdromes of Azerbaijan Republic was carried out for the purpose of defining the basic parameters of the climatic peculiarity that have an impact on the activities of civil aviation. For calculation of the key parameters, mathematical analysis methods are applied on the long-term statistical data.

The article discusses the results of technological studies on the concentration of polymetallic ore of the Chinarsay deposit. The results of studies of the material composition and flotation concentration options for technological samples of ore from the Chinarsay deposit are presented. The results of studying the material composition of ore based on spectral, chemical and rational analysis are presented. It has been established that industrially valuable ore components are lead, zinc and copper, the contents of which are given. It was shown that ore minerals are in close intergrowth with non-metallic ones - quartz, sericite, chlorite, carbonate, etc. It is noted that the studies were carried out in two directions: collective flotation of all ore minerals with further selection of the collective concentrate into lead, zinc, copper and pyrite concentrates and direct collective selective flotation to produce sequentially lead-copper, zinc and pyrite concentrates. As a result of enrichment, lead, zinc and copper concentrates are selected that meet the production requirements.
