Published: April 2022

Day by day the increment in non-linear load has deteriorated the VoltageQuality of power supply system. The crucial concerns originated are VoltageSag and Voltage Harmonics. These power quality problems cause a lot oflosses in the power system which results in commercial losses as well. Themoderation of these issues within the permissible limits is much needed.Among, the several methods and devices that exist, the Dynamic VoltageRestorers (DVR) are often used. This paper focuses on mitigation of Volt-age Sag and Voltage Harmonics. In the development phase of DVR, thedesign of controller is an important phase to be considered. The nonlinearcontrol approach of design is superior to linear control. In this paper theTerminal Sliding Mode Control is used for designing the controller for DVR.To improve accuracy and robustness, an additional nonlinear quantity hasbeen introduced to the equation of traditional Sliding Mode control. TheDynamic Voltage Restorer is modelled using MATLAB/Simulink and used for studies. The simulation results presented validates effectiveness of theproposed control approach.

Authors: Kumari K Krishna , Vanitha V. , G. Hussien Mohamed
Published: April 2022

The transmission line is an essential part of the power system and since itis exposed to the harsh environmental conditions, it is susceptible to opencircuit and short circuit faults. As the occurrence of failures affect the qualityof the electric power supplied, identifying the fault and clearing it quickly iscritical for the reliable power system operation. Fault Diagnostics of a multibus system is crucial for Power system stable operation. In this paper, a ﬁve-bus system is taken up for the study and twelve different types of faults withvarying fault durations are applied in transmission lines at different locations.Then Discrete Wavelet Transform (DWT) is applied to the receiving endcurrent signals of the line and derived wavelet coefﬁcients are used to identifythe type of fault. Simulation and extraction of wavelet coefﬁcients are done in MATLAB Simulink and results are presented. The Model Developed of a ﬁveBus system for Fault Diagnostics and Simulation can be used as Frameworkfor Fault Classiﬁcation and Localization. The derived Wavelet Transformproves to be appropriate for the Framework developed.

In the real world, most countries generate electricity from fuel, which hasits own disadvantages. To minimize the usage of fuels, economic, socialand environmental effects should be studied and focus should be given onthe development of alternative power sources, such as solar photovoltaic(PV), wind energy, micro-hydro power and others. This paper focuses onthe use of solar photovoltaic generation in conjunction with wind turbinesto generate electrical energy. Further, this work studies the hybrid electricalenergy generation system for the selected power network for Debre BerhanCity. The developed hybrid system is connected to the grid to supply the load.Modeling of the power network and the components of the hybrid powernetwork is performed by using MATLAB software. Results show the outputsof wind and solar PV generation are 168.5 kW and 173.3 kW, respectively, tosupply the demand of 200 kW. Therefore, the most suitable option to supply the demand is the combination of solar PV and wind turbines, which produces357.8 kW
Determination of refractive indices for liquid crystals using a double transmission technique
Authors: Chakraborty Susanta , Panchal Rahul , Sinha Aloka
Published: April 2022

We report a new, to the best of our knowledge, approach to determine the refractive indices (RIs) of liquid crystal (LC) systems by considering a double transmission phenomenon of a light beam within the LC medium and the principle of the wedged-cell refractometer. This modified system delivers better spatial resolution of refracted beams in terms of well-resolved spots, compared to the single transmission of a beam in the conventional thin-prism method. The deviation angle obtained in this method is found to be comparatively greater than that of the thin-prism method. The higher values of deviation angle are described using a theoretical model and further experimentally demonstrated for the 5CB nematic LC compound. The variation of the principal RIs (no,ne), and hence the birefringence (Δn) with temperature as well as electric field is investigated for both transmission methods. A relative comparison is carried out between the simulated and standard values obtained from literature. The present technique provides a higher spatial beam resolution to determine the RIs and birefringence of LC systems, which can be very advantageous for different modern photonic applications based on beam shaping and steering.
Reduction of solar infrared heating by using highly transparent thin films based on organic chiral nematic liquid crystal polymer
Authors: Khoshkhati Farid , Mohammadimasoudi Mohammad , Neyts Kristiaan
Published: April 2022

This paper demonstrates a thin and transparent reflector film for the near infrared, based on chiral nematic liquid crystal (CLC) polymers. Two films reflect almost 50% of unpolarized incident light from 730 to 820 nm and from 880 to 1030 nm, while remaining completely transparent in the visible region with transmittance>90%. An efficient window uses the combination of two reflectors. After exposing two window-cubes for 2 h to direct sunlight, the temperature inside the cube with reflector windows was 4°C lower than in cube with plain windows. This reveals that the infrared (IR) reflectors can effectively control the indoor temperature. These films, which are 8 µm in thickness, can be detached from the glass substrates and used as a free-standing film, or be attached to a flexible optical foil or a solid window. The foils can be applied in buildings, offices, and automobiles to statically reduce the energy consumption required for air conditioning or lighting. The free-standing foils show acceptable resistance to polar protic solvents and are thermally stable up to 100°C.

Plasmon absorption reduction in multiple quantum well structures
Authors: Aleshkin V. Ya. , Dubinov A. A.
Published: April 2022

The damping of two-dimensional plasmons in structures with several quantum wells due to absorption by free carriers is studied theoretically. Both gate structures and structures without a gate are considered. It is shown by the example of structures with GaAs quantum wells that an increase in the number of quantum wells while maintaining the electron concentration in each of them leads to a decrease in the damping coefficient of two-dimensional plasmons. The physical reasons for the decrease in the absorption of plasmons are discussed. It is shown that an increase in the number of quantum wells should lead to a decrease in the decay of plasmons in systems with a finite gate width as well.
Multi-class GAN for generating multi-class images in object recognition
Authors: Wang Bingxu , Lan Jinhui , Gao Jiangjiang
Published: April 2022

The current generative adversarial network (GAN) is limited in the application of data augmentation in object recognition. The training of the GAN is unstable, and the generated image quality is poor. Methods such as progressive growing of GANs and multi-scale gradient GAN solve these problems. The packed GAN (PacGAN) solves the problem of mode collapse during training. However, these methods can generate only one type of image at a time, and the training time is long. To solve the above problems, this paper proposes the multi-class GAN (Mc-GAN). It uses an augmented discriminator to train multiple generators at the same time. Through iterative training, the discriminator can accurately judge the output of each generator and guide it to generate the corresponding image. This paper analyzes the optimization process of the objective function of Mc-GAN. Experiments show that the method can generate high-quality images and reduce training time, and it can be used for data augmentation in object recognition. It effectively improves the practicality of GAN.

Published: April 2022

Newcastle disease virus (NDV)-mediated gene therapy is a promising new approach for treatment of cancer but shows limited anti-angiogenesis. VEGF-Trap plays a vital role in anti-angiogenesis. To enhance the anti-tumor effect of NDV, VEGF-Trap gene was incorporated into the genome of rNDV in this study (named rNDV-VEGF-Trap). Results showed that rNDV-VEGF-Trap reduced cell growth ratio by 85.37% and migration ratio by 87.9% in EA.hy926 cells. In vivo studies, rNDV-VEGF-Trap reduced tumor volume and weight of CT26-bearing mice by more than 3 folds. Immunohistochemistry analysis of CD34 showed rNDV-VEGF-Trap significantly decreased the number of vascular endothelial cells in the tumor tissues. Moreover, Western blot analysis demonstrated that treatment with rNDV-VEGF-Trap significantly decreased the phosphorylation levels of AKT, ERK1/2 and STAT3 and increased the expression levels of P53, BAX and cleaved caspase-3 in the tumor tissue. In addition, to evaluate the toxicity of rNDV-VEGF-Trap, serum chemistries were analyzed. The results showed that rNDV-VEGF-Trap caused insignificant changes of creatinine levels, alanine aminotransferase and aspartate transaminase. Furthermore, administration of rNDV-VEGF-Trap did not cause the diarrhoea, decreased appetite, weight decrease and haemorrhage of the experimental mice. These data suggest that rNDV-VEGF-Trap exhibits an enhanced inhibition of CT26-bearing mice by enhancing anti-angiogenesis and apoptosis and may be a potential candidate for carcinoma therapy especially for colon cancer.

Objective

The objective of our study was to explore clinical decisions of psychiatrists regarding the management of common mental disorders in primary care (PC) in four Latin Americans countries, through the application of clinical vignettes.

Methods

Using a cross-sectional design, we conducted a self-administered online questionnaire survey of psychiatrists from Bolivia, Brazil, Cuba, and Chile. The questionnaire covered sociodemographic and professional information. The psychiatrists’ clinical decisions were assessed through three clinical vignettes representing typical PC cases of depression, anxiety, and somatization.

Results

230 psychiatrists completed the online survey. Psychiatrists from Brazil were less likely to recognize depression as a mental disorder than those from Cuba (odds ratio (OR) = 0.30, 95% confidence interval (CI), 0.10 to 0.91, p < 0.04). Female gender (OR = 0.19, 95% CI, 0.04 to 0.91, p < 0.02) and older age (OR = 0.92, 95% CI, 0.87 to 0.97, p < 0.01) reduced the likelihood of agreement that depression cases should be treated by a Primary Care Physician (PCP). In the somatoform symptoms vignette, longer training duration increased the likelihood of agreement that treatment should be done by a psychiatrist instead of a PCP (OR = 1.19, 95% CI, 1.04 to 1.37, p < 0.01). In the anxiety vignette, females (OR = 2.38, 95% CI, 1.10 to 5.13, p < 0.01) and participants from Bolivia (compared with Cubans, OR = 4.19, 95% CI, 1.22 to 14.42, p < 0.02) were more likely to consider that these patients should be treated by a psychiatrist instead of a PCP.

Discussion

Most psychiatrist respondents agreed that patients with depression should be treated by PCPs and that somatoform and anxiety cases should be treated by psychiatrists. These results show that psychiatrists consider that they, and not PCPs, should treat patients with common mental disorders, regardless of the evidence showing that common mental disorders can be treated by primary care physicians in PC.

Published: April 2022

Adipocytes regulate the body’s metabolism by secreting adipokines to maintain energy homeostasis. Asprosin is a new type of adipokine, and its relationship with obesity remains controversial. There are a few reports on the effect of long-term exercise on serum asprosin level. This study aimed to investigate the effects of body mass index (BMI) and exercise/sedentary habit on serum asprosin in male college students as well as the relationship between serum asprosin and body composition and related metabolic indicators and provided a basis for further exploration of the biological function of asprosin. Ninety-six male college students were classified into the sedentary habit group (SD; 48) and the special training experience group (ET; 48). Both groups included three subgroups of normal BMI, overweight, and obesity, with 16 people in each subgroup. One-way analysis of variance, analysis of covariance, and Pearson correlation analysis were performed. The results showed that serum asprosin levels in the obesity subgroup were significantly higher than those in the normal and overweight subgroups. Excluding BMI interference, there were no significant differences in serum asprosin between the SD and ET groups; however, there were significant differences in body composition, tumor necrosis factor-α, interleukin-6, and interleukin-10. Asprosin was positively correlated with BMI, body fat percentage, visceral fat area, fasting insulin, insulin resistance homeostasis model, total cholesterol, low-density lipoprotein, tumor necrosis factor-α, interleukin-6, and leptin levels and was negatively correlated with relative lean body mass, relative skeletal muscle mass, high-density lipoprotein, and interleukin-10, and adiponectin levels. In conclusion, serum asprosin is closely related to body weight, body composition, glucose and lipid metabolism, inflammatory response, and fat hormones. Long-term exercise training cannot prevent BMI increase from increasing serum asprosin level. If the influence of BMI is excluded, long-term exercise training does not affect serum asprosin.
The effect of pandemic prevalence on the reported efficacy of SARS-CoV-2 vaccines
Authors: Sharma Rajeev , Anand Abhijith
Published: April 2022

The efficacy of SARS-CoV-2 vaccines reported in Phase 3 trials varies from ~45% to ~95%. This study tests the hypothesis that the observed variation in efficacy of SARS-CoV-2 vaccine candidates can be explained by the prevalence of the COVID-19 pandemic at trial sites. To test the proposed hypothesis, we conducted a systematic search following PRISMA guidelines. Our search resulted in 8 vaccine candidates that had reported efficacy data from a total of 20 Phase 3 trials, representing a total of 221,968 subjects, 453 infections across the vaccinated groups and 1,554 infections across the placebo groups. We use meta-regression models to analyse the potential associations between prevalence of COVID-19 pandemic at trial sites and efficacy of the reported SARS-CoV2 vaccines. The overall estimate of the risk-ratio is 0.24 (95% CI, 0.17–0.34, p ≤ 0.01), with a high degree of heterogeneity (τ2 = 0.50, I2 = 88.73%). Our meta-regression analysis with pandemic prevalence as the predictor explains almost half the variance in risk ratios across trials (R2 = 49.06%, p ≤ 0.01). This study finds that efficacy of SARS-CoV-2 vaccines reported in Phase 3 trial declines as pandemic prevalence at trial sites increases. Trials conducted in locations with low pandemic prevalence reported higher efficacies as compared to trials conducted in high pandemic prevalence locations.

Background

Osteoporosis affects people worldwide. However, there are few validated tools for the early screening of osteoporosis in Vietnam. We set out to evaluate the performance of the osteoporosis self-assessment tool for Asians (OSTA) and the osteoporosis screening tool for Chinese (OSTC) for the early screening of osteoporosis in postmenopausal Vietnamese women.

Methods

We analyzed retrospective data from 797 postmenopausal Vietnamese women. The bone mineral density (BMD) in the lumbar vertebrae (L1–L4) and the left and right femoral necks of all participants were measured using dual-energy X-ray absorptiometry (DXA). Osteoporosis was defined as the BMD (T-score) < -2.5. The OSTA and OSTC scores were calculated from the age and weight of participants. Receiver operating characteristic analysis was conducted to compare the performance of the two tools with the BMD measurements by DXA at different anatomical sites.

Results

The rates of osteoporosis determined by BMD varied between anatomical sites, and ranged from 43.4% to 54.7% in the lumbar vertebrae and 29.2% and 8.9% in the left and right femoral necks, respectively. For the vertebrae, the area under the curve (AUC) for OSTA ranged from 70.9% to 73.9% and for OSTC ranged from 68.7% to 71.6%. The predictive value of both tools was higher for femoral necks, with the AUC of OSTA for the left and right femoral necks being 80.0% and 85.8%, respectively. The corresponding figures for OSTC were 80.5% and 86.4%, respectively. The highest sensitivity and specificity of OSTA were 74.6% and 81.4%, while these figures for OSTC were 73.9% and 82.6%, respectively.

Conclusion

OSTA and OSTC were shown to be useful self-assessment tools for osteoporosis detection in Vietnam postmenopausal women. Further research is encouraged to determine the applicability of tools for other populations and settings.
Editor’s introduction: New approaches to Mexican cinema
Authors: Pineda Franco Adela
Published: April 2022

The four contributions included in this dossier engage with theoretical approaches that have challenged the suitability of the national as the organizing principle in the study of cultures. Thomas Matusiak and Eduardo Tormos Bigles revisit the trans-national and intra-national dimension of independent and experimental cinema during the 1960s and 1970s through the case studies of Teo Hernández and Alfredo Joskowicz. Olivia Cosentino explores the affective role of the critic spectator by analysing a Mexican non-fiction film. Carolyn Fornoff challenges the idea of national cinema for the case of Mexico through a radical engagement with ecocriticism and energy studies.
A jaguar in Paris: Teo Hernández’s shamanic cinema
Authors: Matusiak Thomas
Published: April 2022

Teo Hernández (Ciudad Hidalgo 1939–Paris 1992) began a prolific career as an experimental filmmaker after entering a self-imposed exile in Paris in 1966. With no formal training, he completed dozens of films on the amateur format of Super 8 before his untimely death at the height of the AIDS epidemic in France. Hernández’s cinema cannot be separated from his postcolonial experience as an undocumented immigrant in Europe. Based on his audio-visual and written work, this article examines how the filmmaker elaborated a unique film theory grounded in an auto-ethnographic appropriation of primitivist tropes. Through this queer exilic cinema, Hernández crafted an authorial persona around the figure of a shamanic filmmaker. I take the films Nuestra senõra de París/Our Lady of Paris (Hernández 1981–82) and Pas de ciel/No Sky () as a point of departure to examine the construction of a cinematic ritual capable of inducing trance in the body of the spectator and the filmmaker.
Alfredo Joskowicz: Corporeal abjection and counterculture in independent Mexican cinema after 1968
Authors: Tormos Bigles Edgardo F.
Published: April 2022

This article examines three films by Mexican filmmaker Alfredo Joskowicz (1937–2012) in the context of the emergence of independent Mexican cinema. As a direct product of the 1968 Student Movement, this filmic corpus stood in direct opposition to the industrial, state-subsidized cinema that was perceived as an emissary of national discursive hegemony. My analysis foregrounds the representation of corporeal abjection as one of the main tropes through which these films enacted countercultural insurrection. I also aim to demonstrate how these three films represent shifts in Joskowicz’s ideological perspective, and how they correspond to the State’s intensifying repression and the concomitant radicalization of leftist opposition. I argue that Jokowicz’s initial representation of bodily abjection first stood as the emblem of an authentic dissidence predicated on biopolitical insurrection, and later acquired a negative, necropolitical valence that effectively delimited a great part of independent cinema’s political-ideological horizon.
A Practical Overview of the Stool DNA Test for Colorectal Cancer Screening
Authors: Anand Sanya , Liang Peter S.
Published: April 2022

The multitarget stool DNA test with fecal immunochemical test (sDNA-FIT) is recommended by all major US guidelines as an option for colorectal cancer screening. It is approved by the Food and Drug Administration for use in average-risk individuals aged 45 years and older. The sDNA-FIT tests for 11 biomarkers, including point mutations in KRAS, aberrant methylation in NDRG4 and BMP3, and human hemoglobin. Patients collect a stool sample at home, send it to the manufacturer's laboratory within 1 day, and the result is reported in approximately 2 weeks. Compared with FIT, sDNA-FIT has higher sensitivity but lower specificity for colorectal cancer, which translates to a higher false-positive rate. A unique feature of sDNA-FIT is the manufacturer's comprehensive patient navigation system, which operates 24 hours a day and provides active outreach for patient education and reminders in the first month after a test is ordered. Retesting is recommended every 1–3 years, although the optimal testing interval has not yet been determined empirically. The cost of sDNA-FIT is $681 without insurance, but Medicare and most private insurers cover it with no copay or deductible.

Intersection of Migration and Local Governance: Lessons on Methods and Research Design
Authors:   University of the Witwatersrand, Mapitsa Caitlin Blaser
Published: April 2022

A recent study interrogating the ways in which municipal authorities in South Africa are governing their mobile communities demonstrated that there is potential for both conceptual innovation and methodological rigor when integrating the cross-cutting systems of migration and local governance. However, this integration also posed a number of challenges that were apparent both during the data collection phase, as well as when the diagnostic tool was designed. The process of implementing this research raised methodological and conceptual questions about how these two areas of work intersect. This paper aims to reflect not on the results of the study itself, but on the methodological process issues that can lay a foundation for a better understanding of how to study the intersection of two interdisciplinary fields. This research took place in five South African municipalities in Limpopo, Gauteng, and Mpumalanga, selected because they reflect a broad spectrum of migration dynamics and demographic patterns. An institutional ethnography approach was drawn on, which included mixed methods fieldwork with document review, key stakeholder interviews, focus groups, and community mapping took place in all five municipalities, taking an inductive approach to developing a diagnostic tool, which was applied retrospectively based on the data gathered. This paper found that resolving a number of divergent conceptual issues is important to effectively interpret results around the intersection of the cross-cutting fields of governance and migration. This methodological reflection is important on its own, but it will also help ensure that future initiatives around strengthening local governance, or making systems more responsive to the needs of migrants, are on solid conceptual, methodological, and practical ground.

Apportionment of authority among states in the space is one of the fundamental function of public international law and aim of that serves state borders institution. State borders are define as a line or surface separating state territories in land, martime and airspace. However exist different kind of borders that their establish in space bases on delimitation and demarcation. As long as do not give rise controversy establish land and maritime borders, while in spite of lack border determine in air space accept that sit height about 100–150 km. To sum up in the light of public international law exists and significant border is submit of principle of territorial integrity of states at the same time by their establish essential role plays crucial role effectiveness in carry out control of territory and borders. Therefore the principle of territorial integrity of States and effectiveness control over territory defines essence and role of state border.
An Examination of Multinational Corporations’ Accountability in the Light of Switzerland’s Failed Responsible Business Initiative in the Covid-19 Pandemic Era
Authors: Ugwu Ikechukwu P.
Published: April 2022

This article examines the efforts made so far in holding multinational corporations (MNCs) liable for human rights and environmental violations in the light of Switzerland’s failed referendum in November 2020, during the peak of the Covid-19 pandemic. It also looks at other international law instruments that have the potential to hold MNCs accountable. While these other laws have failed to achieve the desired result of holding MNCs accountable, the referendum, if it had succeeded, would have triggered a binding vote on a constitutional amendment to introduce compulsory human rights due diligence for companies incorporated in Switzerland, the first of its kind in Europe. The consequencewould have been that victims of Swiss MNCs’ violations would have had the right to bring claims in Switzerland against a defaulting Swiss MNC. Unfortunately, the referendum failed, and to some extent the Covid-19 pandemic negatively affected the referendum outcome, because it was greatly politicised. It became a lost opportunity on what would have been “one small step for [Switzerland], one giant leap for the [international community]”.
The Data-Driven Economy. Remarks in the Light of Selected Issues in the Competition Law
Authors: Jacolik Magdalena
Published: April 2022

Data has begun to play a vital role in global, EU-wide and domestic economies. On 19 February 2020, the European Commission published the EU’s strategy for data, which outlines a new and unprecedented approach to development. The vision thus described – a data-driven economy – is to be implemented within the next five years.However, this broad undertaking gives rise to a number of legal, economic and social issues which deserve to be more thoroughly examined. In this paper, the author considers how the data economy relates to aspects of competition law, including threats associated with the sharing of confidential company data, and information protected under intellectual property laws, among the participants of the market economy, i.e. businesses. Also, observations are made concerning the hypothetical emergence of monopolies and oligopolies, as well as collusive agreements between enterprises on the grounds of the new approach to development.

Published: April 2022

Hybridization ofBrassica napuswith various Brassicaceae species can result in obtaining new forms with increased resistance to blackleg, a dangerous disease caused mainly byLeptosphaeria maculans. In this study, we aimed to correlate the field resistance of selectedBrassicahybrids to blackleg with chromosomal structure revealed by Fluorescencein situhybridization. Tested genotypes varied in the number of chromosomes and rDNA signals. The greatest variation was observed for A1-type chromosomes. Field evaluation also revealed significant differences inL. maculansresistance. Performed analyses allowed to distinguish threeB. napus×Brassica fruticulosagenotypes in which variable patterns of chromosomal structure might be connected to field resistance. However, a more thorough study, including the detection of all A-genome chromosomes, is required.

Published: April 2022

The angle steel member is the most commonly used component form of the transmission tower structure. Considering its connection characteristics, we must deal with its stability analysis under semi-rigid constraint conditions for the proper study of the overall structure’s mechanical performance. Therefore, in order to establish a simple and high-precision method suitable for the ultimate bearing capacity analysis of the transmission tower, we build the refined finite element models of typical steel tower joints, analyze its moment-rotation curve and utilize simulation technique of spring elements to acquire the calculation method of its single angle stability bearing capacity, which is considering initial imperfection and residual stress. Furthermore, we analyze its bearing capacity under different constraint conditions such as rigid, semi-rigid and articulated connection. The results show that it is necessary to consider joint stiffness in the bearing capacity analyses. Finally, it’s confirmed that the calculation results of this method agree well with the experimental data, which validates its high accuracy. Therefore, the method provides technical support for high efficient component stability simulation in overall stability analyses of the transmission steel tower.

Intonation as a cue to epistemic stance in one type of insubordinate clauses
Authors: Fried Mirjam , Machač Pavel
Published: April 2022

This corpus-based study focuses on the spoken nature of insubordination by analyzing intonationvis-à-visinterpersonal functions associated with specific insubordination patterns in spontaneously produced Czech conversations. This paper shows that there is a consistent relationship between the epistemic function of a given variant and its intonational contour: the pattern found in argumentative settings is associated with a conclusive, sharply falling cadence, while the variant found in collaborative contexts and imparting an explicative flavor has a slightly rising melody, suggesting inconclusiveness. We also discovered a clear parallelism between these two intonational variants and an intonational split in the embedded polar questions after the verb formnevím‘I don’t know’, the most likely source of the insubordinate structures. This finding further motivates the interpersonal functions served by the insubordination patterns: the argumentative variant marks a high degree of confidence aboutpnot being true, while the slightly rising contour of the explicative pattern marks a low degree of confidence inpbeing true, thus necessarily projecting tentativeness. The results strengthen the status of these patterns as conventional grammatical units distinct from their syntactic source; they show that their phonic properties provide salient interpretive cues; and they also contribute to the question of how we conceptualize the emergence of insubordination.

Published: April 2022

For the present research, a super ferritic stainless steel model alloy with 4.4 wt.% nickel addition was produced. Due to the increased nickel content, the chromium content was also increased to 25.7 wt.% in order to maintain the ferritic phase stability, including a molybdenum content of 4.6 wt.% to increase the corrosion resistance. A boron content of 0.07 wt.% was also added in order to increase temperability, toughness and stability of grain boundaries. The effect of solution annealing treatments on the microstructure and corrosion resistance of the 0.07 wt.% boron model alloy was studied at temperatures of 1150 °C and 1200 °C for different times. After the solution treatments, there was an increase in the corrosion resistance of the alloy and also for the critical pitting temperature, showing that the solution treatments performed were efficient for the alloy to achieve good properties for industrial applications.
