Authors: Yaremchuk Iryna , Bulavinets Tetiana 
Published: September 2021

The object of research is plasmonic properties copper of monosulfide nanoparticles. One of the most problematic areas is that there is still no unambiguous answer to which main copper monosulfide nanoparticles parameters have a decisive effect on their resonance absorption, scattering or electric field enhancement. It is necessary to study the plasmonic properties of copper monosulfide nanoparticles depending on their main parameter, namely the dielectric constant. The principle of dipole equivalence and Mee-Gans theory for the modeling of the optical nanoparticle characteristics is used. It is found that dielectric constant is a crucial parameter determining the resulting optical response of such nanoparticles. The surrounding medium refractive index affects the position and magnitude of the nanoparticles maximum plasmonic absorption. The nonspherical nanoparticles are characterized by two plasmon peaks corresponding to transverse and longitudinal localized surface plasmon resonance if the ratio between the axes is higher than 1.5. The ellipsoidal nanoparticles exhibit higher sensitivity to changes in the refractive index of the surrounding medium in comparison to the spherical ones. The obtained research results are primarily the basis for further comprehensive research of plasmonic copper monosulfide nanoparticles for their specialized applications. Second, knowledge of the influence of the nanoparticle dielectric constant on their resulting spectral characteristics allow tuning of the localized surface plasmon resonance peak position in a wide wavelength range, from 500 to 1200 nm, using the nanoparticle synthesis technique. Thus, the material under study is promising for sensor applications in a wide spectral range.

The object of research is intumescent fire retardant coatings based on epoxy resins. The research is aimed at the development of mathematical models of the dependence of the swelling rate of intumescent fire retardant coatings on their composition. Considering the complexity of the processes during the formation of a protective carbon layer, it is advisable to select the optimal ratio of the components of an intumescent fire retardant coating experimentally, followed by the construction of mathematical dependences of the swelling ratio on the coating composition. Therefore, experimental studies aimed at developing and optimizing the composition of an intumescent fire retardant coating based on epoxy polymers are an important task. The studies were carried out in accordance with the theory of planning experiments with the construction of an orthogonal compositional plan of the second order. A linear swelling factor was chosen as the response function. Compositions based on the ED-20 epoxy oligomer, cured with polyethylene polyamine and filled with ammonium polyphosphate, aluminum hydroxide, and graphite additive were used for the study. Based on the results of processing the experimental results, a regression equation was obtained and response surfaces were constructed that describe the dependence of the linear swelling coefficient Cs of an intumescent composition based on an epoxy oligomer on the content of ammonium polyphosphate, aluminum hydroxide and graphite additive. A complex relationship is shown between the content of components and the linear swelling coefficient Cs with different ratios of the components. The optimum by the linear swelling coefficient (Cs=68.1) content of the components in the epoxy polymer was determined, amounting to 20 wt. including for ammonium polyphosphate, 15 mass parts including for aluminum hydroxide and 3 mass parts for the graphite additive. However, with such a ratio, the «self-extinguishing» condition is not met (Cs=27 %). Filling the composition with ammonium polyphosphate in an amount of 26.3 mass parts including, aluminum hydroxide 25 mass parts and 3.5 mass parts including graphite additives allows to get an intumescent fire retardant coating with a swelling ratio Cs over 63 and a reduced level of flammability (Ci=31 %)

Baclground. Pathogenic variants of the CREBBP gene have been revealed in patients with Rubinstein-Taybi and Menke-Hennekam syndromes, however, the toe walking symptom was not mentioned in these pathologies.Clinical Case Description. The pathogenic nucleotide variant c.5600G>A in heterozygous state in the CREBBP gene was revealed in our 9-year-old female patient with refractory toe walking and developmental speech delay. There were no abnormalities typical for Rubinstein-Taybi syndrome, but there were several signs of Menke-Hennekam syndrome.Conclusion. The genetic anomaly associated with toe walking is described. This observation allows us to critically relate to the hypothesis about the idiopathic genesis of this form of gait disorder at the absence of obvious neurological or orthopedic causes of its development.

Published: September 2021

Abstract: This study aims to find out what are conversational features used by male and female characters in Game of Thrones season 8, how it is represented in their conversation, and how power and social status affect characters' linguistic behavior. This study used a descriptive qualitative research design. The data of this study are twenty-two conversations taken from episode 1 up to episode 6 of season 8. There are four conversational style features discussed in this study: (1) talkativeness, (2) interruption, (3) compliments, and (4) minimal responses. The results show that all four features are found in the conversations, but they are manipulated differently by male and female characters. Also, the use of gender conversational style features in this case seems universal. Female characters are more talkative which confirms the theory of women’s language. Male characters also use female conversational style more frequently in terms of minimal responses and compliments. However, power plays an important role in this case since it enables characters to be more dominant which reflects that gender is not the only factor to control the conversation.

Abstrak: Penelitian ini bertujuan untuk mengetahui gaya percakapan yang digunakan oleh pemeran pria dan wanita dalam serial berjudul Game of Thrones Season 8, bagaimana gaya tersebut direpresentasikan dalam percakapannya, dan bagaimana kekuasaan dan status sosial mempengaruhi perilaku linguistik karakter. Penelitian ini menggunakan desain penelitian deskriptif kualitatif. Data dalam penelitian ini adalah dua puluh dua percakapan yang diambil dari episode 1 hingga episode 6 di season 8. Ada empat fitur gaya percakapan yang dibahas dalam penelitian ini: (1) tingkat keaktifan berbicara, (2) interupsi, (3) pujian, dan (4) tanggapan minimal. Hasil penelitian menunjukkan bahwa keempat fitur ditemukan dalam series ini, namun dipraktekkan secara berbeda oleh karakter pria dan wanita. Selain itu, penggunaan fitur gaya percakapan gender dalam hal ini terkesan universal. Karakter perempuan lebih banyak bicara yang mana mendukung teori gaya bahasa wanita. Karakter pria juga lebih sering menggunakan gaya percakapan wanita dalam hal memberikan tanggapan minimal dan pujian. Namun, kekuasaan memainkan peran penting dalam hal ini karena memungkinkan karakter lebih dominan dan menjelaskan bahwa gender bukan satu-satunya faktor yang mengendalikan percakapan.

Using both principles, this research was conducted to describe the characteristics of the expository texts in the health news articles. This research used a qualitative approach with a theoretical orientation of discourse analysis. The data in this study are phrases, clauses, and sentences that show the exposition taken from health news presented in the Sindonews.com page. The results showed two findings. First, the structure of news exposition consists of (a) theses which are categorized into theses in the form of proposals, affirmation of facts, and statements; (b) arguments (evidence) in the form of evidence of facts and evidence of opinion; and (c) closing in the form of reaffirmations, recommendations, quotes, highlights or assessments, and conclusions. Second, the pattern of developing news exposition is in the form of a pattern which is categorized into a causal pattern, classification, process, illustration, report, example, and comparison which is categorized into an arrangement of four patterns and two patterns.
