    The technique of optimal design of bearing structures on the basis of genetic algorithm has been suggested. A design of steel frame with varying 9 parameters using the method of finite elements is considered as an example. The best variant corresponding to the volume minimum of the frame material is revealed

    The author reviews the subject scope and the presentations of the inter-university research and practical conference hold on the occasion of the 90-th anniversary of Professor Nikolay Kartashov (1928–2011), a prominent library scientist, an architect of the USSR librarianship, the USSR Honored Worker of Culture. It is Nikolay Kartashov who was the first to substantiate the system approach principle in the library studies, and to develop the concepts of regional and comparative library studies.At the conference, the significance of Kartashov’s personality and science concepts were objectified within the context of modern library science. The participants focused on characterizing Kartashov as a scholar, administrator, and pedagogue. In their discussion, problematic, and practice-oriented papers, theoretical, methodological and methodical aspects were analyzed. The participants were examining the term β€œregional library studies” within the modern context and the possibility to apply this relevant concept in the professional library education and library practice.The Conference specific feature was the wide range of poster papers; the speakers revealed Kartashov’s contribution into the library science and practice, in particular, methodological approaches and theoretical tools of the regional library studies, the concepts of library management based on functional modeling, revamping the system of territorial library services, etc.ΠŸΡ€Π΅Π΄ΡΡ‚Π°Π²Π»Π΅Π½ ΠΎΠ±Π·ΠΎΡ€ ΠΏΡ€ΠΎΠ±Π»Π΅ΠΌΠ°Ρ‚ΠΈΠΊΠΈ ΠΈ ΠΎΡ…Π°Ρ€Π°ΠΊΡ‚Π΅Ρ€ΠΈΠ·ΠΎΠ²Π°Π½Ρ‹ участники мСТвузовской Π½Π°ΡƒΡ‡Π½ΠΎ-практичСской ΠΊΠΎΠ½Ρ„Π΅Ρ€Π΅Π½Ρ†ΠΈΠΈ, посвящённой 90-Π»Π΅Ρ‚ΠΈΡŽ со дня роТдСния профСссора Н.

    BACKGROUND The market of hypnotic and sedative drugs is being updated due to the high toxicity of barbiturates and the limitations of their use. Currently, safer drugs such as Z-drugs, Doxylamine, and some benzodiazepine derivatives are often prescribed for the treatment of anxiety and insomnia, but they can cause acute poisoning if overdosed or in case of nonmedical use.AIM To establish an affordable express thin-layer chromatography (TLC) technique for preliminary screening detection of Doxylamine, Phenazepam and Zaleplon in order to diagnose acute poisoning.MATERIAL AND METHODS Thin-layer chromatography (TLC) and gas chromatography with mass selective detection (GC-MS) methods were used. Urine samples from patients with symptoms of acute Doxylamine, Zaleplon, Phenazepam poisoning, and model urine samples were prepared by liquid-liquid extraction at pH 9.0 with chloroform for TLC analysis, with ethyl acetate-diethyl ether mixture (1:1) for GC-MS.RESULTS We developed the TLC method of Doxylamine, Zaleplon and Phenazepam detection which helps reveal their presence in the patient’s urine, as well as distinguish one from another in case of similar toxic symptoms. The GC-MS method was used for confirmatory analysis. Compared to confirmatory methods, the developed technique of TLC screening is expressive, does not require expensive high-tech equipment, while allowing to differentiate Doxylamine, Zaleplon and Phenazepam from each other and from other toxicologically significant psychoactive substances detected in general screening.ΠΠšΠ’Π£ΠΠ›Π¬ΠΠžΠ‘Π’Π¬ Π Ρ‹Π½ΠΎΠΊ снотворных ΠΈ сСдативных лСкарствСнных ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚ΠΎΠ² обновляСтся Π² связи с высокой Ρ‚ΠΎΠΊΡΠΈΡ‡Π½ΠΎΡΡ‚ΡŒΡŽ Π±Π°Ρ€Π±ΠΈΡ‚ΡƒΡ€Π°Ρ‚ΠΎΠ² ΠΈ ограничСниями ΠΈΡ… использования.

    The article discusses the issues of measuring the heart rate during human movement in remote monitoring systems. The algorithm of heart rate measurement based on the processing of spectrograms of cardiograms is described. The implementation of the algorithm makes it possible to obtain a more accurate quantitative assessment of the heart rate in real time in the presence of interference and noise
