Проаналізовано вплив медіа-технологій на соціальне середовище і показано, що розробки в області нанотехнологій, робототехніки, мемрісторной електроніки, що пронизують всі рівні живої і неживої матерії, стають глобальними загрозами. Технології NBICS задають нову стратегію розвитку цивілізації, і їх потенційні наслідки вимагають гуманітарного осмислення як перспектив, так і загроз її реалізації. Сама людина стає свідком нового еволюційного стану цивілізації і трансформується під впливом комплексу сучасних медіа-технологій. Доведено, що медіа-технології змінюють повсякденне життя людей, їх спілкування, спосіб їх безпосереднього особистого буття, а світ людини під впливом медіа-технологій, медіасоціума і медіакультури трансформується в його Медіасвіт. Розкрито соціогуманітарна функціональність цифрових медіа-мереж як цифрових посередників і охарактеризовано їх вплив на соціально-природне середовище проживання людини.The article shows that the modern media environment is a qualitatively new stage in the transformation of the media environment, since there is not only an intensification of the level of development of science and technology, new structures of social life and ways of organizing production, but also the formation of new forms of sociality, understanding of human nature and his transformation. The influence of media technologies on the social environment is analyzed and it is shown that developments in the field of nanotechnology, robotics, memristor electronics, which penetrate all levels of living and non-living matter, become global threats. NBICS technologies set a new strategy for the development of civilization, and their potential consequences require a humanitarian reflection on both the prospects and the threats to its implementation. A human himself becomes a witness to a new evolutionary state of civilization and is transformed under the influence of a complex of modern media technologies. It is proved that media technologies are changing the everyday life of people, their communication, the way of their direct personal being, and the human world under the influence of media technologies, media socium and media culture is transformed into his media world. The socio-humanitarian functionality of digital media networks as digital mediators is revealed and their influence on the social-natural environment of human habitation is characterized.В статье показано, что современная медиасреда представляет собой качественно новый этап трансформации медиасреды, поскольку происходит не только интенсификация уровня развития науки и технологий, новых структур общественной жизни и способов организации производства, но и также формирование новых форм социальности, понимание природы человека и его трансформация.

Доказано, что медиа-технологии меняют повседневную жизнь людей, их общение, способ их непосредственного личного бытия, а мир человека под влиянием медиа-технологий, медиасоциума и медиакультуры трансформируется в его медиамир. Раскрыта социогуманитарная функциональность цифровых медиа-сетей как цифровых посредников и охарактеризовано их влияние на социально-природную среду обитания человека

Anthroponotic transmission of Cryptosporidium parvum predominates in countries with poorer sanitation - a systematic review and meta-analysis

Background: Globally cryptosporidiosis is one of the commonest causes of mortality in children under 24 months old and may be associated with important longterm health effects. Whilst most strains of Cryptosporidium parvum are zoonotic, C. parvum IIc is almost certainly anthroponotic. The global distribution of this potentially important emerging infection is not clear. Methods: We conducted a systematic review of papers identifying the subtype distribution of C. parvum infections globally. We searched PubMed and Scopus using the following key terms Cryptospor* AND parvum AND (genotyp* OR subtyp* OR gp60). Studies were eligible for inclusion if they had found C. parvum within their human study population and had subtyped some or all of these samples using standard gp60 subtyping. Pooled analyses of the proportion of strains being of the IIc subtype were determined using StatsDirect. Meta-regression analyses were run to determine any association between the relative prevalence of IIc and Gross Domestic Product, proportion of the population with access to improved drinking water and improved sanitation. Results: From an initial 843 studies, 85 were included in further analysis. Cryptosporidium parvum IIc was found in 43 of these 85 studies. Across all studies the pooled estimate of relative prevalence of IIc was 19.0% (95% CI: 12.9–25.9%), but there was substantial heterogeneity. In a meta-regression analysis, the relative proportion of all C. parvum infections being IIc decreased as the percentage of the population with access to improved sanitation increased and was some 3.4 times higher in those studies focussing on HIV-positive indivduals. Conclusions: The anthroponotic C. parvum IIc predominates primarily in lower-income countries with poor sanitation and in HIV-positive individuals. Given the apparent enhanced post-infectious virulence of the other main anthroponotic species of Cryptosporidium (C. hominis), it is important to learn about the impact of this subtype on human health

Intensification of heat transfer behind the backward-facing step using tabs

The influence of tab size and location on the flow structure, distribution of pressures on the surface, and heat transfer in the separation region behind the backward-facing step at Reynolds number Re = 4000 was experimentally investigated. The effect of tabs on the distribution of the local pressure and heat transfer coefficients in the longitudinal and transversal directions was studied. The presence of tabs significantly intensifies the heat transfer directly behind the separation point and brings the region of maximum heat transfer closer to the step. There is a strong uneven distribution of pressure coefficients and Nusselt numbers in the transverse direction due to the formation of vortical wake. The results of measurements are compared with the case of using two-dimensional obstacles in the form of solid ribs; the features of the development of the flow and heat transfer behind 3D tabs are analyzed. It is shown that the main difference in the installation of two-dimensional and three-dimensional obstacles is observed mainly in the immediate vicinity of the flow separation point at X/H < 6
