A simple design of a tunable ultra-broadband metamaterial absorber of terahertz (THz) radiation based on vanadium dioxide (VO2) configurations is proposed, having wide incidence angle tolerance and polarization insensitivity.

The Article dwells on semantic-functional and stylistic application of synonyms in contemporary Armenian poet, journalist Ara Aloyan's "Do not light up" and "Footprints in watercolour" collections of poems. Article discusses the stylistic application of synonyms, the semantic-functional features of the members of the group of synonyms, the stylistic application thereof which not only enriched the author's vocabulary and ensured the diversity of speech, but also provided an opportunity to stand out from many contemporary authors.

LILIT GEVORGYAN - ANTONYMS AND ANTITHESES IN THE COLLECTIONS OF POEMS "DON'T GET LIGHT" AND "FOOTPRINTS WITH WATERCOLOR" BY A. ALOYAN Within the framework of this article, the stylistic expressions of the antonyms and antitheses extracted from in the collections of poems "Don't become illuminated" and "Footprints with watercolor" written by poet Ara Aloyan have been discussed. Their semantic fields and lexical groups, their use in the writer's poetry as a way of expressing the objective world, objects, phenomena, poetic sentiments, feelings, emotions and thoughts have been studied.

This work presents a framework that explores human-environment and/or socio-ecological system (HES, SES) resilience to natural hazards. HES is presented as a system of five forms of capital i.e. social, economic, physical, governance and natural. The five forms of capital are reviewed such that the social capital refers to the union of social and human capital in their classical definitions from five forms of capitals model of Sustainable Livelihood Framework, apart from governance. Governance, however, is discussed as separate capital for of its central role in disaster risk management. Besides, the domain of natural capital is also expanded to incorporate both natural resources and ecosystem services. Resilience as Interaction-Outcome model is proposed to illustrate that hazard as an external driver affects both HES subsystems and the interactions between their elements. This framework addresses the internal drivers as an interaction space with all the processes between and inside each of the capital. It is to illustrate that the general interaction space has another smaller and/or intrinsic level of interactions, which is defined by a certain hazard, whereas the newly developed interactions define the outcome such as damages and losses etc.

To evaluate factors associated with tuberculosis (TB) treatment outcomes in human Immunodeficiency Virus-Associated (HIV) TB patients in Armenia, we conducted a nation-wide cohort study using routine programmatic data of all HIV-associated TB patients receiving TB treatment with first- or second-line drugs from 2015 to 2019. Data were obtained from the TB and HIV electronic databases. We analysed occurrence of the combined unfavourable outcome (failure, lost to follow-up, death and not evaluated) and death separately, and factors associated with both outcomes using Cox regression. There were 320 HIV-associated TB patients who contributed a total of 351 episodes of TB treatment. An unfavourable TB treatment outcome was registered in 155 (44.2%) episodes, including 85 (24.2%) due to death, 38 (10.8%) lost to follow up, 13 (3.7%) failure and 19 (5.4%) not evaluated. Multivariable analysis showed that receipt of Antiretroviral Treatment (ART) [ART start before TB treatment: adjusted hazard ratio (aHR)=0.3, 95% confidence interval (CI): 0.2-0.5, aHR=, 95% CI:, 95% CI:, 95% CI:TB meningitis (aHR=4.4, 95% CI: 1.6-11.9) increased the risk. The risk of death was affected by the same factors as above in addition to the low BMI (aHR=2.5, 95% CI: 1.3-4.5) and drug resistance (aHR=2.3, 95% CI: 1.0-5.4). In the subsample of episodes receiving ART, history of interruption of ART during TB treatment increased the risk of unfavourable outcome (aHR=2.1 95% CI: 1.2-3.9), while ART start during TB treatment was associated with lower risk of both unfavourable outcome (within first 8 weeks: aHR: 0.5, 95% CI: 0.3-0.9; after 8 weeks: aHR: 0.4, 95% CI: 0.2-1.0) and death (within first 8 weeks: aHR: 0.2, 95% CI: 0.1-0.4; after 8 weeks: aHR: 0.1, 95% CI: 0.01-0.3). The rates of unfavourable TB treatment outcomes, and death in particular, among HIV-associated TB patients in Armenia are high. Our findings emphasize the protective effect of ART and the importance of proper management of cases complicated by drug resistance or meningitis.

Within the last 10 years some growth of active tuberculosis(TB) cases have been observed among contacts with latent TB infection (LTBI) in Armenia Aims and objectives: to reveal cases of active TB disease among contacts with LTBI. Methods: 115 families (main group) with active TB cases(sputum smear positive)from 4 socially disadvantaged areas of Armenia have been observed.95% of members of contact families had positive tuberculin skin test results.Among them 125(24%) adults and children got the disease within the last few years(about 2-3 members in each of 31 families - 71 persons in total).51 families (control group) with active TB cases(sputum smear positive) have been observed for comparison. Results: it was established that in the main group the families with epidemiologically disadvantaged factors were prevailing(73,1%),such as patients with massive bacterial excretion and drug resistance (39,3%), social and medico-biological aggravating factors,comorbidity.It shows that the development of TB disease among people with LTBI is determined by not only massive bacterial excretion but also by social and medico-biological risk factors.Among persons with TB disease the cases under 35 year turned out to be dominating for both sexes.The morbidity of TB disease among persons with LTBI have exceeded during different years(30-40 times). Conclusions: The risk of getting the disease for LTBI persons who are in a long and close contact with persons who have active TB (sputum smear positive)increases in the case of existence of drug resistance, medico-biological and social aggravating factors, comorbidity and appears in 6 months after the first contact.
