Published: May 2022

A number of studies have investigated the phenomenon of teachersâ€™ talk to explain its role in the process of acquiring a target language in a classroom setting. However, studies of teachersâ€™ talk in the field of communicative competence and it sub-competence have not much done yet. Three English teachers at SMAN 1 Semarang, SMA Nasional Karangturi Semarang, and SMA Mardisiswa Semarang were involved in this spoken discourse study to explain the realization of actional competence which proposed by Celce_Murcia et al. (1995) and formulaic competence based on the Biber et alâ€™s. (2004) theory in teachersâ€™ talk. Furthermore, this study also explained the relationship between those competencies. The findings of this study revealed that English teachers mostly performed actional competence in five sub-categories namely asking questions, giving instructions, explaining, reacting to interlocutorsâ€™ speech, and complementing. Related to the realization of lexical bundles, teachersâ€™ talk mainly contained verb phrase along with dependent clauses. In contrast, lexical bundles that incorporate noun phrase and preposition fragments accounted for only a small proportion of lexical bundles. Dealing with the relationship between both competences, it revealed that there is a stock of lexical bundles on each language function. Seeing there is a relationship between both competences, the teachers must choose appropriate utterances in a given situation as the model for the students. The teachers need to maintain a balance, they are not only focused on grammar and pronunciation, but also have adequate knowledge and competence of lexical bundles for performing appropriate language functions.

Published: May 2022

This study aimed to explain the appraisal resources manifested in argumentative essays written by undergraduate students with high and low proficiency level, as well as their similarities and differences of using appraisal resources. This study employed qualitative research in the form of written discourse analysis. The appraisal resources checklist adapted from Martin and White (2005) is used to determine the distribution of appraising items of attitude, engagement and graduation in argumentative essays written by high and low proficiency students. Out of 16 students chosen as the sample, 8 students are categorized as having high proficiency level, and the others eight belong to low proficiency level. The results of this study revealed that both groups of students utilized all subsystem of appraisal resources. However, high proficiency students dominantly used engagement rather than attitude and graduation. Meanwhile, the lows one utilized more attitude than engagement and graduation. In term of attitude, high proficiency students produced more appreciation. It showed that the argumentative essays written by high proficiency students are more appreciative than emotional and judgmental to align their personal voices in conveying their thoughts and opinions. In addition, in term of engagement, both groups dominantly applied entertain item in which it showed that both groups of students are successful to show their authorial voice towards the topic given. Finally, in graduation feature, force is dominantly used by both groups of students which means that they tried to intensify and quantify their arguments to build strong persuasion.

Authors: Coban H.B. 
Published: May 2022

Abstract
Proteases hold an important position in today's world commercial enzyme market. Among various microbial producer genera, Bacillus is leading the commercial protease production. However, industry is still actively looking for new microbial protease producers with distinctive properties. Therefore, this study was undertaken for the evaluation of protease production by Bacillus megaterium DSM 32 strain in terms of its protease productivity, calculation of various production kinetics, partial characterisation of the enzyme, and modelling the protease production process. As results, the highest protease activity, specific cellular protease production rate, and protease productivity were calculated as 255.42 U mL−1, 36.2514 U g−1, and 16.1313 U mL−1 h−1, respectively, in shake flask fermentations. Partial characterisation studies showed that the enzyme has 45 °C and pH 8 as optimum working conditions, and its activity increased by 24% with the addition of 5 mM Mn+2 to the reaction medium. Additionally, the enzyme showed high stability and kept almost full activity in a cell-free medium for 20 days at 4 °C. Furthermore, modified Gompertz model provided the best fit in describing protease production with the lowest error and high fit values.

High-current pulsed electron beam surface treatment is a method of materials modifying, which improves the mechanical properties of metal materials. Due to high-speed heating, evaporation, recrystallization, as well as plastic deformation, dislocations with high density are formed in the surface and, as a result, an increase in indicators of various physical and mechanical properties, such as hardness, wear resistance, etc., is observed. Since currently high-entropy alloys are a relatively new class of materials, the effect of pulsed electron beam treatment on the dislocation substructure has not yet been established. In this work, a non-equiatomic high–entropy alloy of the Co – Cr – Fe – Mn – Ni system, made using a wire-arc additive manufacturing, was subjected to surface treatment using a high-current pulsed electron beam with an energy density of 30 J/cm2. By the method of studying thin foils using transmission electron microscopy, it was found that the treatment does not affect the chemical composition of the alloy, but leads to serious changes in the dislocation substructure. A nonmonotonic change in the scalar density of dislocations was revealed, reaching a  maximum value of 5.5·1010 cm–2 at a distance of 25 µm from the irradiation surface. It is shown that an undirected cellular dislocation substructure with cell sizes from 400 nm to 600 nm is formed at this distance from the surface. With further distance from the surface at a distance of up to 45 µm, the dislocation substructure changes from cellular to cellular-mesh. At a distance of 120 – 130 µm, the effect of a high-current pulsed electron beam is not observed – the substructure corresponds to the substructure of the initial alloy with a chaotic distribution of dislocations.

Published: May 2022

Based on the state diagrams of two–component silicate systems SrO – SiO2 , BaO – SiO2 , CaO – SiO2 , the authors have determined the activity of components in invariant (eutectic and monotectic) points of the systems under consideration. Crystallization processes at invariant eutectic points l1 and l2 are considered as chemical reactions le1 (KSiO2 (l) + lMeO(l)) → CSiO2 (sol) + α(MeO·SiO2 )(sol), le2 (mSiO2 (l) + nMeO(l)) → (MeO·SiO2 )(sol) + b(2MeO·SiO2 )(sol), for which the values ΔG°T and the equilibrium constants were established. The values of aMeO in the slags were determined at given temperatures and known values of the component activities in metal melts in equilibrium with slag. In homogeneous slag melts, the activity of alkaline-earth metal (AEM) oxides was defined from the constants of equilibrium reactions of reduction of these metals from slags by silicon of iron-silicon metal melts. In the zone of homogeneous slag melts, the dependences aSiO2 = f (x(SiO2 )) were constructed at temperatures of 1600 and 1700 °C, and when using data on the activities of AEM (Sr, Ba, Ca) in metallic high-silicon melts, the dependences lga(SrO) = f (x(SiO2 ) , x(Si)) at 1493 °C and lga(BaO) = f (x(SiO2 ) , x(Si)) at 1450 °C were determined. On a three-parameter diagram in coordinates a[Si] – a(SiO2 ) – a(MeO) (for AEM), the dependencies a(SrO) = f (a[Si] , a(SiO2 ) ) at 1493 °C and a(BaO) = f (a[Si] , a(SiO2 ) ) at 1450 °C were constructed. It is shown that low equilibrium values of a(SrO) and a(BaO) , lga(SrO) = f (a(SiO2 ) , a[Si] ) ≤ (–4) and lga(BaO) = f (a(SiO2 ) , a[Si] ) ≤ (–3), can be achieved at equilibrium values of silicon activity in metal melts a[Si] > 0,5 during strontium reduction and a[Si] > 0,7 during barium reduction.

Objective: to evaluate clinical outcomes in patients with prostate cancer treated with high-dose-rate (HDR) brachytherapy (BT) as monotherapy.Materials and methods. From January 2015 to December 2017, 97 men with localized prostate cancer underwent HDR-BT as monotherapy, with a temporary implant on a MicroSelectron HDR device. The dose prescription was: 30 Gy in 2 fractions with an interval of 2 weeks. The overall and biochemical survival rate was assessed. The assessment of genitourinary and gastrointestinal toxicity was also carried out. The quality of life associated with urination before treatment and in dynamics during 5 years of observation, as well as the frequency and degree of development of erectile dysfunctionand its dynamics during the entire observation period were analyzed.Results. The median age was 65.2 (44 to 80) years. Overall, 29 patients had low risk prostate cancer, 63 patients had moderate risk, and 5 patients – high risk. The follow-up period was five years (range, 18 to 72 months). The median follow-up was 54.3 (95 % confidence interval 52.3–59) months. Overall survival and survival without biochemical recurrence were 96 and 99 %, respectively. Toxicity was assessed according to the RTOG/EORTC (Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer) scale for each event. Late genitourinary toxic reactions of grade 1 and 2 were noted in 23.9 and 6.3 %, respectively. Late gastrointestinal grade 2 toxicity was not observed. Genitourinary and gastrointestinal toxic reactions of grade 3 were not observed. The quality of life associated with urination after treatment was comparable to the level of quality of life at the time of inclusion of patients in the treatment protocol. Erectile dysfunction developed to a greater extentin the first 1–2 years after HDR-BT with a subsequenttendency to recovery.Conclusion. HDR-BT as monotherapy is a safe and highly effective treatment for localized prostate cancer. The fractionation mode in the form of 30 Gy for 2 fractions of 15 Gy with an interval of 2 weeks with or without dose modulation in the area of the tumor focus using a gel has a low toxicity profile from the side of critical organs.

Background. Prostate cancer is one of the actual problems of modern oncology. The incidence of prostate cancer is steadily increasing despite of popularization of screening and early diagnostics. It is worth to highlight separately the castration-resistant prostate cancer which develops on the average 2 years after surgical or medicinal castration. For the patients with metastatic castration-resistant prostate cancer (mCRPC) the main purpose of treatment is increasing of overall survival while maintaining the quality of life. Currently there are several treatment options for mCRPC: chemotherapy, inhibitors of androgen receptor pathway,systemic alfa-radiotherapy, PARP-inhibitorsfor homologousrecombination DNA repair deficiency. Using of several sequential lines of mCRPC therapy leads to maintaining the patients’ quality of life and increasing its duration. Systemic alfa-radiotherapy is using since 2013 – the first is radium-223 which was approved by Food and Drug Administration according the results of the phase III trial ALSYMPCA. In Russian Federation radium-223 was approved in 2016.Objective: to evaluate the efficiency and safety oftherapy with radium-223 as well as pain response at patients with mCRPC.Materials and methods. 67 patients were included in this analysis who received radium-223 therapy at Scientific Research Institute of Tomsk National Research Medical Center of Russian Academy of Sciences and Tomsk Regional Oncology Dispensary.Results and conclusion. Radium-223 has demonstrated its efficiency for mCRPC patients with good safety profile and positive pain response and maintaining the QoL.

Objective. To study the impact of augmentation mammoplasty on some aspects of body image-related quality of life, motivation and self-esteem.
Materials and methods. Seventeen women were surveyed 6-14 months after augmentation mammoplasty using the BIQLI and ASI-R questionnaires.
Results. The aspects of body image-related quality of life associated with physical activity and desire to change one's appearance were higher in younger people with lower body weight. The volume of installed breast implants was inversely proportional to the feeling of confidence and happiness in everyday life (R = 0.6). The larger was the volume of implants, the less was the responsibility for life events (R = 0.8). In the long-term period after mammoplasty, a subjective level of the quality of life increased in 53 %, on average by 0.2 (p0.05), significantly only for the motivation scale and the question "feelings of personal dignity and self-respect". Negative dynamics was found for the following aspects: "When I meet new people", "At work (study)" and "Relationships with friends", for all other answers positive one. The older the patients were, the more attention they paid to their appearance (R = 0.7) and compared themselves with the others (R = 0.6), thought about what the others think about their appearance (R = 0,6), more often thought about how they look like in different situations (R = 0.6).
Conclusions. Preoperative studying of motivation allows more differentially determining the indications for surgery and risk of postoperative dissatisfaction. Augmentation mammoplasty often improves the body image-related quality of life, motivation and self-esteem.

Objective. To study the relationship of polymorphism of the genes of aldosterone synthetase CYP11B2 (C-344T), adrenergic receptor type 1 ADRB1 (Gly389Arg) and type 2 ADRB2 (Arg16Gly) with the risk of obesity.
Materials and methods. The study involved 170 patients; the mean age was 45.4 7.3 years. The patients were divided into 2 groups: group 1 obese patients with metabolic disorders in combination with 1-2 degree hypertension complicated obesity (n = 90); group 2 50 participants with obesity without metabolic disorders (metabolically healthy obesity). The control group consisted of 100 healthy respondents. All the surveyed persons underwent anthropometry and general clinical studies according to the recommendation for examination of patients with obesity and arterial hypertension. Total DNA was isolated from venous whole blood samples by RT-PCR using the DNA-Sorb-B kit.
Results. It was found that in the group of complicated obesity, the carriage of the TT genotype of the CYP11B2 gene polymorphism (C-344T) and the CG genotype of the Gly389Arg polymorphism of the ADRB1 gene prevailed in comparison with the group of metabolically healthy obesity and healthy respondents. The predominance of carriage of the GG genotype of the ADRB2 gene polymorphism (Arg16Gly) was revealed in the groups of metabolically healthy obesity and complicated obesity in comparison with the healthy group. An association of the polymorphic position of the ADRB1 (Gly389Arg) and ADRB2 (Arg16Gly) genes with the level of low-density lipoprotein cholesterol, triglycerides, the level of systolic blood pressure and diastolic blood pressure, and the level of uric acid was established. The relationship between the polymorphism of the CYP11B2 (C-344T) promoter region and the level of glomerular filtration rate and total cholesterol was determined.
Conclusions. Analysis of ADRB1 (Gly389Arg), ADRB2 (Arg16Gly), and CYP11B2 (C-344T) gene polymorphism variants can be used as an additional marker to assess the risk of developing obesity, arterial hypertension, and metabolic disorders.
