A prototype of an electronic nose (e-nose) system integrating a set general-purpose gas sensors, module, and signal processing classification methods has been designed implemented to detect certain environmental odors that might pose risk human health. The proposed device explores the filter diagonalization method (FDM), advanced technique for accurate spectral estimation, presence together with random forest (RF), popular machine learning algorithm, classify features such spectra....
Lactones are among the well-known organic substances with a specific taste and smell. They characterized by antibacterial, antiviral, anti-inflammatory, anti-cancer properties. In recent years, this group of compounds, new biologically active have been searched modifying main (leading) structure analogs stronger or different responses that may toxic effect on cells pathogenic bacteria constitute an alternative to commonly used antibiotics. A preliminary study δ-lactone derivatives as...
An enzymatic route for phosphorous-carbon- bond formation is developed by discovering new promiscuous activity of lipase. This biocatalytic transformation addition leads to biologically and pharmacologically relevant α-acyloxy phosphonates with methyl group in α-position. A series target compounds were synthesized yields ranging from 54% 83% reaction Candida cylindracea (CcL) lipase via Markovnikov H-phosphites vinyl esters. We carefully analyzed the best conditions given such as type...
The study examines the peculiarities of use information systems and digital technologies, digitization organization logistics processes, increasing volume e-commerce, personalization services, as well management relationships with consumers enterprises various types economic activity.These questions are especially relevant in conditions rapid development economy.The expediency a comprehensive approach to transformation customer service enterprise has been demonstrated.A statistical analysis...
A preliminary study of 2-amino-4-aryl-3,5-dicarbonitrile-6-thiopyridines as new potential antimicrobial drugs was performed. Special emphasis placed on the selection structure target pyridine derivatives with highest biological activity against different types Gram-stained bacteria by lipopolysaccharide (LPS). Herein, Escherichia coli model strains K12 (without LPS in its structure) and R2–R4 (with lengths were used. Studied compounds provided yields ranging from 53% to 91% lipase-catalyzed...
An enzymatic route for phosphorous-carbon bond formation was developed by discovering new promiscuous activity of lipase. We reported a metal-free biocatalytic method the synthesis pharmacologically relevant β-phosphonomalononitriles via lipase-catalyzed one-pot Knoevenagel-phospha-Michael reaction. carefully analyzed best conditions given reaction: type enzyme, temperature, and solvent. A series target compounds synthesized, with yields ranging from 43% to 93% reaction Candida cylindracea...
The impact of substituent at phenyl ring diethyl benzylphosphonate derivatives on cytotoxic activity was studied. organophosphonates were obtained based developed palladium-catalyzed α, β-homodiarylation vinyl esters protocol. new synthetic pathway toward 1,2-bis(4-((diethoxyphosphoryl)methyl)phenyl)ethyl acetate proposed which significantly improves the overall yield final product (from 1% to 38%). Several newly synthesized tested as potential antimicrobial drugs model Escherichia coli...
Assessing the position of economic and human capital development level, building a strategy to improve quality life is extremely important for state, so study indicators that form have greatest impact on it remains relevant.Since very concept multicomponent category, characterized by both objective subjective indicators, we consider appropriate structure knowledge about factor environment shapes life, their reflection forming cognitive model, its static analysis identify factors which...
Маркетингове середовище компанії складається із зовнішніх факторів і сил, які суттєво впливають на маркетингові рішення та стратегії, а також загальну ефективність компанії. Аналіз маркетингового середовища є ключовим елементом успішного управління маркетингом бізнесом, оскільки допомагає компаніям адаптуватися до змін, реагувати нові виклики забезпечувати конкурентну перевагу ринку. Багатофакторність відображена у складових мікросередовища (клієнти, постачальники, посередники, конкуренти,...
The research article deals with different regulatory and doctrinal (mostly based on Polish Ukrainian sources) concepts of foreign occupation current means its enforcement, providing a description the legal, political social consequences caused by it, which are primarily suffered civilian population as non-combatant, possibility full or partial retrospective analogy.The authors have concluded when occupation, from one hand, is committed aggressively to seize alien territory enslave list...
Abstract: Resistance of fish to diseases in natural conditions is much higher than artificial breeding conditions. The appearance pathogenic bacterial flora combination with dangerous parasites the result a biocenotic imbalance. One factors causing are abiotic factors. Human interference farming (e.g. feeding, fertilizing, aeration) sometimes also disturbs this balance. Decaying food and plant debris promote putrefactive processes creation favorable for microorganisms including bacteria,...
W artykule przeglądowym omówiono obawy związane z żywiołowym rozwojem i upowszechnianiem systemów bazujących na generatywnej sztucznej inteligencji (GenAI) oraz ich wpływem bezpieczeństwo, a także dotychczasowe wysiłki regulacyjne zmierzające do narzucenia ograniczeń w rozwijaniu stosowaniu takich rozwiązań trosce o poszanowanie podmitowości człowieka ważnych ludzkich dóbr rezultaty. Rozbieżności percepcji, ocenie akceptacji zagrożeń wynikające odmiennych wizji bezpieczeństwa są czynnikiem...
Systemy wspomagania decyzji w handlu na rynku walutowym okazały się przydatne, jeśli nie niezbędne. Stopień ich skuteczności predykcyjnej zależy od skonstruowanego modelu i dobranych danych. Podstawowe informacje do budowy modeli pochodzą z historii kursu interesującej nas pary walutowej określonych przedziałach czasowych. Reszta danych pochodzi wybranych wskaźników określających, co może być przyczyną takich właśnie wahań kursowych walut danym czasie. Wskaźniki te różnych źródeł, jak teorie...
