    The laser induced fluorescence (LIF) spectra A1Sigma ~ b3Pi --> X1Sigma+ of KCs dimer were recorded in near infrared region by Fourier Transform Spectrometer with a resolution of 0.03 cm-1. Overall more than 200 LIF spectra were rotationally assigned to 39K133Cs and 41K133Cs isotopomers yielding with the uncertainty of 0.003-0.01 cm-1 more than 3400 rovibronic term values of the strongly mixed singlet A1Sigma+ and triplet b3Pi states. Experimental data massive starts from the lowest vibrational level v_A=0 of the singlet and nonuniformly cover the energy range from 10040 to 13250 cm-1 with rotational quantum numbers J from 7 to 225. Besides of the dominating regular A1Sigma+ ~ b3P Omega=0 interactions the weak and local heterogenous A1S+ ~ b3P Omega=1 perturbations have been discovered and analyzed. Coupled-channel deperturbation analysis of the experimental 39K133Cs e-parity termvalues of the A1S+ ~ b3P complex was accomplished in the framework of the phenomenological 4 x 4 Hamiltonian accounting implicitly for regular interactions with the remote states manifold. The resulting diabatic potential energy curves of the interacting states and relevant spin-orbit coupling matrix elements defined analytically by Expanded Morse Oscillators model reproduce 95% of experimental data field of the 39K133Cs isotopomer with a standard deviation of 0.004 cm-1 which is consistent with the uncertainty of the experiment. Reliability of the derived parameters was additionally confirmed by a good agreement between the predicted and experimental termvalues of 41K133Cs isotopomer. Calculated intensity distributions in the A ~ b --> X LIF progressions are also consistent with their experimental counterparts.Comment: 17 pages, 14 figure

    Objective: to evaluate the efficiency of methods for diagnosing and treating critically ill patients with acute respiratory failure (ARF) in acute poisoning by neurotropic substances. Subjects and methods. Two hundred and thirty-three patients with acute severe intoxication with neurotropic poisons were examined. All the patients were admitted for toxic-hypoxic coma and ARF; in this connection all the patients underwent artificial ventilation (AV). The patients were divided into 3 groups: 1) those in whom the traditional treatments (AV, detoxifying therapy, and infusional and cardiotropic support) could restore the basic parameters of vital functions, as judged from the recovered oxygenation index; these patients had no metabolic shifts; 2) those who had signs of pulmonary hyperhydration, low cardiac output and moderate metabolic disorders, as suggested by elevated lactate levels; 3) seriously ill patients in whom the interval between the time of poisoning to care delivery was more than 20 hours; the patients of this group had the most significant metabolic disorders. Results. Correction of ARF in critically ill patients with acute poisoning should include, in addition to the rational parameters of AV and detoxifying therapy, agents for targeted therapy for sequels of hypoxia and energy deficiency states. For maximally rapid and effective oxygen transport recovery, the addition of perfluorane to the complex therapy cardinally improves the results of treatment and reduces mortality rates. Conclusion. The complexity of the pathogenesis of ARF and its sequels is a ground for diagnosing and correcting not only ventilation disturbances, but also pulmonary microcirculatory disorders and metabolic disturbances. Key words: acute intoxication with neu-rotropic poisons, acute respiratory failure, pulmonary hyperhydration, hypoxia, metabolic disturbances.Цель исследования — оценить эффективность методов диагностики и терапии больных в критическом состоянии с острой дыхательной недостаточностью (ОДН) при острых отравлениях веществами нейротропного действия. Материал и методы. Приведены результаты обследования 233 пациентов с острыми тяжелыми отравлениями ядами нейротропного действия. Все больные поступали в токсико-гипоксической коме, с ОДН, в связи с чем всем больным проводили ИВЛ. Больные были разделены на 3 группы: первая группа — больные, у которых использование традиционных методов лечения (ИВЛ, детоксикационная терапия, инфузионная и кардиотропная поддержка) позволяло восстановить основные параметры жизнедеятельности, о чем можно было судить по восстановлению индекса оксигенации; у этих больных отсутствовали метаболические сдвиги; вторая группа — это пациенты с признаками гипергидратации легких, низким объемом сердечного выброса и с умеренно выраженными метаболическими расстройствами, о чем свидетельствовало повышение лактата; третья группа — наиболее тяжелые больные, у которых от момента отравления до оказания помощи прошло более 20 часов; у больных этой группы были наиболее выражены метаболические нарушения. Результаты. Коррекция ОДН у больных в критическом состоянии при острых отравлениях, наряду с рациональными параметрами ИВЛ и детоксикационной терапией, должна включать средства для направленной коррекции последствий гипоксии и энергодефицитного состояния. Включение перфторана в состав комплексной терапии с целью максимально быстрого и эффективного восстановления транспорта кислорода позволяет кардинально улучшить результаты лечения и уменьшить летальность. Заключение. Сложность патогенеза ОДН и ее последствий является основанием для диагностики и коррекции не только вентиляционных нарушений, но и нарушений микроциркуляции в легких и метаболических расстройств. Ключевые слова: острые отравления ядами нейротропного действия, ОДН, гипергидратация легких, гипоксия, метаболические нарушения

    The results of comparative determination of the values of stroke volume (SV) and cardiac index measured by integral rheography (IRG) after M. I. Tishchenko, thermodilution (using a Swan-Ganz catheter), and echocardiography (EchoCG) were studied in 139 patients with acquired heart diseases (AHD) and coronary heart disease (CHD) in different periods after cardiosurgical operations under extracorporeal circulation. The reasons for lowering SV measured by rheography were revealed. The changes in the oscillations of terminal circulatory vessels, which are associated with altered ejection fraction and decreased capillary blood flow velocity pulse under the action of different doses of adrenaline, were shown to affect the genesis of rheograms. The problem in assessing the nature of blood flow (pulsation) in the terminal portion of the circulatory system in emergency medicine is discussed.У 139 пациентов с приобретенными пороками сердца (ППК) и ишемической болезнью сердца (ИБС) проведен анализ результатов сравнительного определения значений УО и СИ, измеренных методами интегральной реографии (ИРГТ по М. И. Тищенко), терморазведения (катетер Сван — Ганса) и эхокардиографии (ЭХОКГ) в разные сроки после кардиохирургических операций в условиях экстракорпорального кровообращения. Выявлены причины снижающие значения УО, измеренного реографическим методом. Показано влияние на генез реограмм изменений пульсовых колебаний сосудов терминального отдела кровообращения, связанных с изменением фракции изгнания, снижением скорости кровотока в капиллярах, и на фоне действия различных доз адреналина, оказывающего констрикторное действие на сосуды. Обсуждается проблема оценки характера кровотока (пульсации) в терминальном отделе системы кровообращения в медицине критических состояний

    Harnessing collective intelligence for the future of learning – a co-constructed research and development agenda

    Learning, defined as the process of constructing meaning and developing competencies to act on it, is instrumental in helping individuals, communities, and organizations tackle challenges. When these challenges increase in complexity and require domain knowledge from diverse areas of expertise, it becomes difficult for single individuals to address them. In this context, collective intelligence, a capacity of groups of people to act together and solve problems using their collective knowledge, becomes of great importance. Technologies are instrumental both to support and understand learning and collective intelligence, hence the need for innovations in the area of technologies that can support user needs to learn and tackle collective challenges. Use-inspired research is a fitting paradigm that spans applied solutions and scientific explanations of the processes of learning and collective intelligence, and that can improve the technologies that may support them. Although some conceptual and theoretical work explaining and linking learning with collective intelligence is emerging, technological infrastructures as well as methodologies that employ and evidence that support them are nascent. We convened a group of experts to create a middleground and engage with the priorities for use-inspired research. Here we detail directions and methods they put forward as most promising for advancing a scientific agenda around learning and collective intelligence
