Authors: Talipov Linar N. , Velichko Evgeny G. , Semenov Vyacheslav S. 
Published: July 2020

Introduction. Corrosion of reinforcement in concrete structures is rather expensive for the economy of any country. Current statutory documents offer two main directions — primary and secondary protection. One of the promising areas of primary protection methods is the use of complex anti-corrosion additives in concrete due to its technological simplicity and economic efficiency. Passivators and surfactants (SAS), as components of such additives, are of particular interest. Sodium nitrite is offered as a passivator, and polycarboxylate molecules (PCE) — as a SAS. The additive of sodium nitrite together with PCE has a visual synergistic effect. Materials and methods. Identification of structural characteristics of the molecules of the obtained PCE polymers was determined by methods of exclusion gel-permeation chromatography and 13C NMR spectroscopy. To study the synergetic effect of NaNO2 + PCE additive, the samples were kept in the models of pore liquid, after which the morphology of their surface was studied by methods of scanning electron microscopy and electron probe microanalysis. Results. The texture and surface color of the presented micrographs indicate surface formations on the samples stored in the models of pore liquid with different anti-corrosion additives. Electron probe microanalysis showed increased concentrations of carbon, oxygen and sodium on the surface of samples stored in pore concrete liquid models with the addition of a complex anti-corrosion additive of sodium nitrite and PCE, which indicates increased concentrations of PCE and possible increased pH on the steel surface. Based on the data acquired, the mechanism of formation of a protective film layer using complex anti-corrosion additive NaNO2 + PCE is offered. Conclusions. Justification of synergetic effect of complex polycarboxylate anti-corrosion additive in the model of concrete pore liquid opens up prospects for research of such additives to the concrete model.

Published: July 2020

Introduction. The formation mechanism of longitudinal screw streams (LSS) along the upstream and downstream face of submerged vanes (SV) is considered. Acting along with the artificial transversal circulation (ATC), these streams protect the water intake from the channel sediments. The intensities and directions of LSS and ATC depend on the regime of flow, the planned-geometric characteristics of the vanes. Recommendations concerning the purpose of SV’s rational characteristics in the aspect of steady formation of all three protective streams in the flow for river damless intakes are contradictory and require clarification. The purpose of the study is to analyze the velocity rate of the LSS in SV site at various planned-geometric characteristics of the vane and hydraulic modes of its operation based on a physical model with an erosion-resistant channel (without water separation), as well as to determine an efficient range of setting angles of the SV’s to the tray board in terms of formation of steady and intensive LSS along the upstream and downstream face of the vane.
Materials and methods. Model physical hydraulic studies and theoretical calculations were used. Five hydraulic modes of SV’s operation were studied, with various planned-geometric characteristics, using the physical model with an erosion-resistant channel (without water separation). The obtained experimental data were summarized and analyzed.
Results. Results of laboratory hydraulic studies of LSS velocity rate in LSS site were presented. Experimental graphic dependence diagrams were plotted characterizing the intensity and direction of the LSS along upstream and downstream faces of the vane.
Conclusions. A determining influence of the setting angle of the vane to the tray board (bank line) on the intensity and direction of the LSS in SV’s site was found out. Experimentally, an efficient SV setting angle was determined in terms of the formation of steady and intensive LSS along the upstream and the downstream vane face with practically usable direction.

Introduction. In the field of implementation of integrated programs of housing construction as a promising direction from the point of view of solution of the most important problems of modern development of the construction industry (intensive growth of urban areas, low quality and high cost of new housing, poor infrastructure), the key task has been set: rationale of the characteristics of the complex of construction sites taking into account interrelations between the number and characteristics of residential buildings and infrastructure facilities. Based on the results of the analysis of the relevant scientific literature, the conclusion was made that the existing tools are limited and fully take into account the key features of the implementation of integrated programs of housing construction. Relevance of research which objective is development of a method of substantiation of characteristics of a complex of construction sites is substantiated.
Materials and methods. The organizational and process characteristics method of the complex of construction sites on the basis of linear fractional programming, which implies the determination of the optimal number of housing construction sites and infrastructure facilities in the context of different instances and categories by the criterion of maximizing the profitability index of the corresponding construction project was developed. The key elements of the developed method are optimization models, which are linear relatively unknown variables and therefore implemented using simplex method in modern software environments of optimization modeling.
Results. The developed method is implemented on a practical example using Microsoft Excel software environment and the “Solution Finder” add-in. As a result of performance of corresponding calculation procedures, concrete values of quantity of sites and infrastructure facilities within the limits of the building project have been received.
Conclusions. On the basis of adequate results obtained from the implementation of the proposed methodology on practical example, the conclusion was made about the high practical significance of the developed tool. The main shortcomings of the developed method are revealed, connected with the absence of consideration of factors of influence of features of a transport infrastructure and technological resources within the limits of construction procedure on characteristics of the project. In order to eliminate the identified shortcomings, it is planned to improve the methodology at further stages of the research.

OBJECTIVE
To evaluate temporal prevalence trend, cardiometabolic risk factors, and the risk of atherosclerotic cardiovascular disease (ASCVD) and all-cause mortality (ACM) in incident young- and usual-onset type 2 diabetes.

RESEARCH DESIGN AND METHODS
From the U.K. primary care database, 370,854 people with a new diagnosis of type 2 diabetes from 2000 to 2017 were identified. Analyses were conducted by age-
group (18–39, 40–49, 50–59, 60–69, 70–79 years) and high-/low-risk status without history of ASCVD at diagnosis, with subjects with two or more of current smoking, high systolic blood pressure, high LDL cholesterol (LDL-C), or chronic kidney disease classified as high risk.

RESULTS
The proportion of people aged &lt;50 years at diagnosis increased during 2000–2010 and then stabilized. The incidence rates of ASCVD and ACM declined in people aged ≥50 years but did not decrease in people &lt;50 years. Compared with people aged ≥50 years, those aged 18–39 years at diagnosis had a higher proportion of obesity (71% obese) and higher HbA1c (8.6%), and 71% had high LDL-C, while only 18% were on cardioprotective therapy. Although 2% in this age-group had ASCVD at diagnosis, 23% were identified as high risk. In the 18–39-year age-group, the adjusted average years to ASCVD/ACM in high-risk individuals (9.1 years [95% CI 8.2–10.0]/9.3 years [8.1–10.4]) were similar to the years in those with low risk (10.0 years [9.5–10.5]/10.5 years [9.7–11.2]). However, individuals aged ≥50 years with high risk were likely to experience an ASCVD event 1.5–2 years earlier and death 1.1–1.5 years earlier compared with low-risk groups (P &lt; 0.01).

CONCLUSIONS
Unlike usual-onset, young-onset type 2 diabetes has similar cardiovascular and mortality risk irrespective of cardiometabolic risk factor status at diagnosis. The guidelines on the management of young-onset type 2 diabetes for intensive risk factor management and cardioprotective therapies need to be urgently reevaluated through prospective studies.

Published: July 2020

The quality of ice cream is largely determined by the type of emulsifier used. The utilization of an appropriate emulsifier will produce ice cream with good quality. A mixture of Mono-Diacylglycerol made from fully Hydrogenated Palm Kernel Oil (furthermore in this paper we named it as MDAG) and Tween-80 in various comparisons was used as an emulsifier in ice cream making and their effects were analyzed. The composition of the mixture was determined based on 5 types of HLB values, namely 4.5 (E1); 5.3 (E2); 6.1 (E3); 6.9 (E4); and 7.7 (E5); obtained from a mixture of MDAG and Tween-80 (87.5: 12.5); (80.8: 19.2); (74.2: 25.8); (67.5: 32.5); and (60.8: 39.2), respectively. The five treatment levels of the mixture composition of the two types of emulsifiers were arranged in a completely randomized design with 4 replications. The parameters observed were overrun, melting time, texture, and consumer preferences for taste and overall acceptance. The data obtained were statistically analyzed using ANOVA, followed by Duncan New Multiple Range Test (DNMRT) . The results showed that the composition of the mixture of MDAG and Tween-80 had a very significant effect on overrun, melting time, texture, taste, and overall acceptance of the ice cream produced. The best quality ice cream was obtained from the mixture composition of MDAG and Tween-80 at HLB 6.1 with MDAG: Tween-80 (74.2: 25.8) with an overrun value of 68.43%, melting time of 21.13 minutes, texture score of 4.76 (as good as a local commercial ice cream produced in Kumpeh District, Muaro Jambi), preferences score of taste was 5.92 (from a score interval of 1-7), and an overall acceptance score was 5.56 (from a score interval of 1-7).

Nutmeg oleoresin microcapsule is the solid, liquid, and gas coating technology of the nutmeg fruit. The purpose of this study was to know how mace nutmeg oleoresin microcapsules could preserve the broiler chicken meat at room temperature during 4 days of observation. The experimental design used was a Completely Randomized Design (CRD) consisting of 5 treatments with mace concentration of nutmeg microcapsules oleoresin (0, 50, 100, 150, and 200) ppm. The variables observed were water content, pH value, total microbes, and organoleptic properties (color, aroma, and texture). The results showed that mace nutmeg oleoresin microcapsules did not affect (p> 0.05) water content and sensory properties of broiler chicken meat, but had a significant effect (p <0.05) on the pH value and total microbe at the same day of room temperature storage. Panel organoleptic test results on the level of preference for meat color, aroma, and texture of chicken meat were in the range score of 3 (somewhat like) to 4 (somewhat dislike). The treatments of nutmeg oleoresin did not affect (p> 0.05) on color, the aroma, and the texture of broiler chicken meat. This research shows that marinating using oleoresin microcapsules has not been effective as a preservative to broiler chicken meat at room temperature.

Published: July 2020

Many tertiary students do not complete all the steps of their tertiary education because they encounter difficulties in adjusting themselves to university life. The aim of this research was to determine the role of upbringing (by both father and mother) and the “college self-efficacy” (the self-confidence of the students in completing their study obligations) regarding college adjustment (CA) [US term] of first-year students of the Faculty of Technology of University X [name concealed], in Bandung, West Java, Indonesia. 139 students were involved in this research, and completed an instrument to measure the research variables. The research data was processed, using regression analysis, to determine the contributions of patterns of upbringing and self-efficacy of the students, regarding college adjustment. Based upon the analysis conducted in the research, the results indicated that the parenting style and college self-efficacy generally had a role in the college adjustment of the student. However, the results more especially indicated that a pattern of permissive maternal upbringing had a significant negative contribution to their CA, and that college self-efficacy had a significant positive contribution to that CA. This paper then discusses the magnitude of the role of the parent, compared to the self-efficacy of the student in his or her achievements, when undertaking tertiary education.

Banyak mahasiswa tidak menyelesaikan jenjang sarjana karena mengalami hambatan penyesuaian diri di masa kuliah. Tujuan dari penelitian ini adalah mengetahui peran pola pengasuhan (ayah dan ibu) dan college self-efficacy (keyakinan diri mahasiswa menyelesaikan kewajiban studi) terhadap college adjustment (CA) mahasiswa Fakultas Teknik tahun pertama Universitas X Bandung. 139 mahasiswa tergabung dalam penelitian ini dan mengisi instrumen yang mengukur variabel penelitian. Data penelitian diolah dengan analisis regresi untuk menentukan kontribusi pola asuh dan keyakinan diri mahasiswa terhadap college adjustment. Berdasarkan analisis yang dilakukan dalam penelitian ini, hasil penelitian menunjukkan parenting style dan college self-efficacy secara umum berperan terhadap college adjustment mahasiswa. Akan tetapi, hasil lebih khusus menunjukkan pola asuh permisif ibu berkontribusi signifikan negatif terhadap CA, dan college self-efficacy berkontribusi signifikan positif terhadap CA. Tulisan ini kemudian membahas besaran peran orangtua apabila dibandingkan dengan keyakinan diri mahasiswa dalam keberhasilannya menempuh pendidikan tinggi.

The fictional narrative is a form of literature often found in everyday life, such as in novels or short stories, comic strips in newspapers, and in poetry. Reading fictional literature has a positive effect, however previous research had not as yet shown any conclusive evidence that such reading increases empathy. This research was aimed at testing the influence of reading fictional narratives on empathy, mediated by narrative engagement. The method used in the research was an experimental one, with a pre-test/post-test control group design. 194 undergraduate students were actively involved as the research participants. The results of the analysis of data, using a Wilcoxon signed-rank test and a causal step approach indicated that reading a fictional narrative may significantly increase the empathy of the reader, and that the relationship of these two variables were partially mediated by narrative engagement. This research provided supportive data to the idea that fictional narratives may raise levels of empathy and that that influence is mediated by the variable of narrative engagement. The public is enjoined to read fictional narratives, such as novels, comics, short stories and poetry of a variety of genres, to experience an increase in empathy.

Fiction narrative merupakan jenis bacaan yang sering ditemui dalam kehidupan sehari-hari, seperti buku novel atau cerita pendek, komik panel di surat kabar, maupun puisi. Membaca bacaan fiktif membawa dampak positif, akan tetapi penelitian terdahulu belum menunjukkan bukti yang konklusif bahwa membaca bacaan fiktif meningkatkan kemampuan empati. Penelitian ini bertujuan untuk menguji pengaruh membaca fiction narrative terhadap empati dengan dimediasi oleh narrative engagement. Metode yang digunakan dalam penelitian ini adalah eksperimen dengan pretest-posttest control group design. Terdapat 194 orang mahasiswa S1 aktif terlibat sebagai partisipan penelitian ini. Hasil analisis data dengan Wilcoxon signed-rank test dan causal step approach menunjukkan bahwa membaca fiction narrative dapat meningkatkan empati pembacanya secara signifikan, serta hubungan kedua variabel tersebut dimediasi secara parsial oleh narrative engagement. Penelitian ini menjadi dukungan data bahwa fiction narrative dapat meningkatkan empati serta pengaruh tersebut dimediasi variabel narrative engagement. Masyarakat disarankan untuk membaca bacaan fiction narrative seperti novel, komik, cerita pendek, maupun puisi dari berbagai genre agar mengalami peningkatan empati.
