Improvement of Corrosion Resistance of Maraging Steel Manufactured by Selective Laser Melting Through Intercritical Heat Treatment
Authors: Mahmood Khan Hamaid , Özer Gökhan , Safa Yilmaz Mustafa , Tarakci Gürkan 
Published: January 2022

Selective laser melting allows the layerwise fabrication of bespoke designs, creating new prospects in applications and properties compared to conventional methods. Like other ultra-high-strength steels, maraging steels offer a high toughness/strength ratio. However, additively prepared maraging steels’ lower ductility and strain-hardening limit their commercial adaptability. Studies exist that show superior mechanical performance is attainable through martensite-to-austenite reversion. However, their impact on corrosion properties is not well understood. In the present study, maraging steel specimens were tempered close to austenite forming temperatures to investigate the reversed austenite effect on maraging steels’ pitting behavior. X-ray diffraction, scanning electron microscopy, and energy-dispersive x-ray spectroscopy were used to characterize selective laser melting samples’ microstructure. To characterize and analyze the pitting performance, potentiodynamic polarization and open-circuit potential were performed in a 3.5 wt% NaCl solution. The intercritical heat-treatment within α’ + γ range of 720°C shows that reversed austenite precipitated mainly along the martensite laths boundaries. The local Ni enrichment as a result of intermetallic particles’ dissolution enables the nucleation of reversed austenite. As a result, the 720°C-tempered specimen exhibits a higher pitting potential, lower corrosion current density, and lower corrosion rate than the as-printed, aged, and homogenized (without reversed austenite) specimens. This study shows that the reversed austenite enhances the pitting resistance of maraging steels.
Gestionar para la convivencia inclusiva, una deuda del modelo educativo salvadoreño
Authors: Avelar Carmen 
Published: January 2022

Este artículo intenta ser una reflexión sobre la influencia de la gestión escolar para generar espacios de convivencia inclusiva. Dicha reflexión está acompañada de algunas interrogantes: ¿qué se entiende y cómo se ve la convivencia y cuál es su enfoque? ¿Cuál es el modelo de gestión que predomina en el centro escolar tomado para el estudio de caso? Para responder a estas interrogantes, se realizó una investigación bajo la metodología de estudio de caso en un centro escolar de uno de los municipios priorizados del Plan El Salvador Seguro (PESS). Se desarrollaron entrevistas, grupos de discusión y un diagnóstico sobre convivencia inclusiva cuyos resultados permitieron tener un primer acercamiento a los procesos de gestión que se llevan a cabo en un centro escolar en contexto de violencia e inseguridad de pandillas; asimismo, se indagó si estos procesos de gestión están posibilitando verdaderos espacios de convivencia inclusiva o si, por el contrario, están perpetuando el ciclo de violencia y exclusión.

El árbol quemado. Linaje y tiempo en El absoluto de Daniel Guebel y La familia de Gustavo Ferreyra
Authors: Zangrandi Marcos 
Published: January 2022

This article studies the configuration of the family in two recent Argentine novels, La familia by Gustavo Ferreyra and El absoluto by Daniel Guebel. Starting from a recognition of the attributes that the family had in the tradition of the novel, this text examines the values that these two novels built around genealogy, lineage and kinship. At the same time, the article study the articulations with the concept of gender in relationship with two fictions not clearly related to this contemporary pattern of reading and fiction production. Finally, this article analyzes the temporal variables, an aspect that is linked to the time allotted to the family through lineage and reproduction. The extensive, profuse and unconventional configuration of this novels indicates a divergence with respect to this assignment and the possibility of other forms and binders of the family.

Contextual Influences in Readings of Nehemiah 5: A Case Study
Authors: Williams Gary R. 
Published: January 2022

A survey of the literature on Nehemiah 5 reveals how contemporary context influences the interpretation and application of the text, for good and for ill. Application must adapt to contemporary needs, but our context may blind us to a passage’s most obvious implications. Interpretation is both illumined and skewed by contextual concerns. Some principles are offered for reading aright the Scriptures in light of text, content and contextual differences.
The Achaean Federal Cult Part 1: Pseudo-Julian, Letters 198
Authors: Spawforth Antony J. S. 
Published: January 2022

This paper explores the evolution of emperor-worship at Corinth in the first century A.D. Specifically, it argues that a Greek ‘letter’ in the correspondence on the emperor Julian should be redated to c. A.D. 80-120 and identified as a petition from the city of Argos to the Roman governor of Achaia, in which the Argives sought exemption from payments towards the cost of celebrations of the imperial cult at the Roman colony of Corinth. Since these celebrations involved many of the province’s cities, the paper goes on to argue that they can be identified with the collective cult—its place of celebration previously uncertain— known from inscriptions to have been founded by the member-cities of the Achaean league in the mid-first century A.D.
The Epistle to the Galatians and Classic Rhetoric: Parts 1 & 2
Authors: Fairweather Janet 
Published: January 2022

Is it a useful or valid approach to St. Paul’s Epistles to analyse them in terms derived from the classical Greek and Roman rhetorical theorists? In the following three-part exploration of this question, of which the first two parts appear here and the third is to be published in the next issue of Tyndale Bulletin, the main focus of attention is the Epistle to the Galatians. Part 1 presents a demonstration that rhetorical criticism of a quality which deserves the attention of modern readers is applied to Paul’s writing in the Commentary on Galatians by St. John Chrysostom. Part 2 re-examines with necessary scepticism the general question of Paul’s relation to pagan Hellenic culture as a whole and rhetoric in particular. Evidence is found for consciousness on Paul’s part of sophisticated rhetorical concepts, but it remains debatable whether, in his youth, he had studied any non-Jewish Greek literature. Part 3 begins with a close reading of Galatians in relation to classical theory on proems, narratives, arguments and conclusions, and poses the question, ‘What justification did Paul have for regarding his discourse as somehow distinct from the σοφία of this world?’ It often proves possible to parallel Paul’s rhetorical strategies in pagan theory and practice. However, it emerges that at the most fundamental level, notably in the bases of his argumentation, his approach was genuinely quite distinct from pagan sophistic.

In a field experiment, conducted during 2018-19 and 2019-20 at the Research Farm, Indian Agricultural Research Institute, New Delhi, factorial combinations of two levels of FYM (0, 10 Mg ha−1) applied to maize; four levels of nitrogen (0, 60, 120, 180 kg N ha-1) and three levels of phosphorus (0, 30, 60 kg P2O5 ha−1) applied to both maize and wheat and subsequent residual effects on green gram were compared. The RGR was at peak in maize at 29oC and in wheat at 12-13 oC. Integral of LAD and incidental solar radiation has significantly improved CGR. The LAD and CGR also shown significant relationship with grain/ seed yield in all three crops. Slightly higher NAR in combination with LAD and SRD can significantly contribute to overall performance of crops. Results indicated that variation in yield across years due to weather fluctuations, irrespective of treatments, was about 16.7 per cent in maize (kharif), 7.93 per cent in wheat (rabi) and 16.8 per cent in green gram (summer).
Forecasting model for disease risk period in chickpea x collar rot pathosystem
Authors: SANJU TAMANG  , POLY SAHA  
Published: January 2022

Collar rot caused by Sclerotium rolfsii Sacc. is one of the major biotic constraints of chickpea production worldwide. It is soil-borne fungi having wider host range and infection mainly occurs at the juvenile stage of crop growth resulting crop failure in no time. The pathogen is greatly influenced by soil temperature (ST) and soil moisture (SM) therefore, experiment formulated to develop a suitable forecasting model for its future use in computer simulation of plant disease prognostication by feeding only soil temperature and moisture data. The popular desi type chickpea variety Anuradha sown at different dates to get a range of soil temperature and soil moisture combination and its corresponding effect on disease incidence was recorded under natural epiphytotic conditions. The data obtained were analyzed using binary logistic regression and discriminant analysis to assess disease risk and non-risk period. The model developed was Y'= -73.9 + 1.251 SM + 0.017 ST. The outcome recorded, a unique statistically significant contribution of soil moisture (p value=0.029) on the establishment of the disease whereas, the effect of soil temperature was detected as statistically non-significant. The model developed and the correctness of the model determined to predict the disease severity with 80 % accuracy.
