Effect of post-weld heat treatment on 6156 aluminum alloy joint formed by electron beam welding
Authors: Wang Shaogang , Xu Junke , Wang Yongpeng 
Published: February 2023

Abstract
The 6156 aluminum alloy is welded by electron beam welding, and different post-weld heat treatments (PWHTs) are carried out on the joints. The microstructure, mechanical property, and corrosion behavior of the welded joint before and after PWHT are investigated, respectively. Results show that the fusion zone is composed of columnar crystal and equiaxed grain in as-welded (AW) condition. There are mainly α-Al matrix phase, and some strengthening phases β″(Mg2Si) and Q(Al4CuMg5Si4) in weld metal. After PWHT, the quantity of strengthening phases in weldment is greatly increased, and their distribution is also improved. The tensile strength of welded joint is 65.8% of that of the base metal (BM) in AW condition. After the heat treatment of HT2, the strength coefficient of joint reaches 85.1%. There are many dimples on the tensile fracture surface, and the joint obviously presents the characteristic of ductile fracture. The electrochemical corrosion performance and resistance to intergranular corrosion of weldment in AW condition are higher than that of the BM. However, they are decreased to a certain extent after PWHT. Compared with that of the AW joint, the resistance to intergranular corrosion is slightly decreased after PWHT, and that of the HT2 joint is the best among them.
Priscian’s Latin: new insights from the manuscript tradition
Authors: Spangenberg Yanes Elena 
Published: February 2023

Abstract
The paper deals with a selection of linguistic features of Priscian’s Latin (6th century AD), namely the use of the indefinite pronoun and adjective after a negation, the declension of Greek loan-words with nominative ending in -ys, and the use of verbal moods and tenses in concessive clauses. The inquiry takes advantage of the new ongoing collation of the 8th–10th-century manuscripts of the Ars Prisciani, which enables ascription to Priscian’s linguistic use of some peculiar syntactic and morphological features that had been obliterated by the standardizing attitude of the former critical editor, Martin Hertz.
Consonant epenthesis in Latin
Authors: Oniga Renato , Re Alessandro 
Published: February 2023

Abstract
This paper intends to focus on two aspects: how the Latin grammarians developed the concept of epenthesis, and how we can now give an explanation to this phenomenon. After having gathered the phonological evidence from the tradition of Latin philology, we propose that, in prehistoric Latin, the epenthesis of -t- in the -s.r- cluster, and the epenthesis of -p- in the -m.l- cluster, aimed at solving some problems in syllabification, that is avoiding an illicit syllable onset and an illicit coda-onset sequence, respectively. We then observe that, in classical Latin, the only productive process is the epenthesis of -p- in the -m.s- and -m.t- clusters, which has the function of fulfilling the faithfulness constraint on the inflection of the -m- stems, blocking the m > n assimilation process that later took place in the evolution from Latin to Italian.

Published: February 2023

Abstract

Context
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders in children and often goes untreated. A major barrier to treatment is the stigma surrounding the disorder, including from the educational and scientific community. Person-centered language (PCL) is associated with positive health outcomes, and its implementation is recommended by multiple professional groups, but its use has not been quantified for ADHD.

Objectives
The goal of this study is to quantify the adherence to PCL among ADHD-related journal publications utilizing a cross-sectional study design.

Methods
We conducted a cross-sectional examination including a systematic search of PubMed, which encompasses MEDLINE, for ADHD-related articles from January 2014 to March 2021. All journals with at least 20 ADHD-related search returns, human research, and in the English language were included, totaling 5,308 articles from 88 journals. Articles were randomized, and the first 500 were screened for inclusion of prespecified, non-PCL terminology. After exclusion, 311 articles were retained.

Results
Of the 311 retained articles, 131 (42.1%) adhered to PCL guidelines. Among articles with non-PCL, stigmatizing language such as “problem(s) with [the/a] child or problem child” and “suffers from” was found most frequently— occurring in 47.6% (148/311) and 5.8% (18/311) of the articles, respectively. We found no significant association between PCL adherence and study characteristics.

Conclusions
Our findings revealed that over half of the current ADHD literature did not adhere to PCL guidelines. Adherence to PCL by the scientific and medical community will increase the overall efforts to mitigate stigma and increase support for individuals with ADHD.
A dual role of proton pump inhibition on cancer: a critical review
Authors: Edizer Deniz Tuna , Akcali Zeynep , Leblebici Asım , Korkut Sıla Övgü , Ellidokuz Ender 
Published: February 2023

Abstract
Proton pump inhibitors (PPIs) are widely used to suppress gastric acid secretion. Proton pumps belong to the family of ATPase and among them P-ATPase and V-ATPase types regulate intracellular as well as extracellular acid equilibrium. The main aim of the current survey is to present the existing literature putting forth the relation between cancer with both the use of PPIs and proton pumps from positive and negative aspects. To perform an objective study, various types of proton pumps and their relation to cancer have been taken into account. Up to date, the studies have been considered in the time range from 2011 to 2021 via various databases (PubMed, Scopus, and Google Scholar). H+/K+ ATPase, located within the gastric parietal cells, is one of the most important examples of P-ATPases. The findings of the literature review along with criticism were presented as decreased P-ATPase expression can be used as a marker for gastric cancer diagnosis whereas the association of the proton pump with cancer may be mainly due to V-ATPase. In conclusion, molecular, epidemiological, and bioinformatic studies are required to enlighten the subject.
More than words: Eine mehrsprachigkeitsorientierte Perspektive auf die Dilemmata von Street-level Bureaucrats in der Klient*innenkommunikation
Authors: Holzinger Clara , Draxl Anna-Katharina 
Published: February 2023

Zusammenfassung
In „super-diversen“ Migrationsgesellschaften ist die Frage nach dem Umgang mit Pluralität entscheidend und folgenreich für soziale Gerechtigkeit. Insbesondere sprachliche Diversität stellt für öffentliche Organisationen, die in einem Spannungsfeld zwischen gesellschaftlicher Mehrsprachigkeit und monolingualer Orientierung agieren, eine Herausforderung dar. Ausgehend von der Annahme, dass Sprache neben der mittelnden stets auch eine soziale Funktion hat, analysiert der vorliegende Beitrag, wie sprachliche Pluralität auf der Beziehungsebene die professionelle Interaktion zwischen Street-level Bureaucrats und Klient*innen prägt. Die Daten stammen aus dem qualitativen Forschungsprojekt AMIGS, das den Umgang mit sprachlicher Diversität am österreichischen Arbeitsmarktservice untersucht. Die Analysen zeigen, dass die Beziehungsarbeit mit Herausforderungen und Paradoxien verbunden ist, welche im Kontext migrationsgesellschaftlicher Mehrsprachigkeit verschärft auftreten können und zusätzliche Dimensionen aufweisen.

Generating electricity during peak hours in Asuncion, Paraguay, through anaerobic digestion of cultivated water hyacinths
Authors: Maioli A. , Pulfer J. , Mitjans F. 
Published: February 2023

The objective of the present paper is to present an innovative and sustainable proposal for generating electricity in the metropolitan area of Asuncion, the capital of Paraguay, based on a renewable source of energy. Electricity would mainly be generated during peak hours with the aim of reducing power contracted by the Paraguayan Electricity Administration (ANDE) from existing hydroelectric power plants and thus reduce costs and stabilise transmission and distribution grids in the area of Asuncion. Electricity would be generated at a 130 MW combined cycle thermal power plant using biogas as fuel, this being obtained by anaerobic digestion of water hyacinths cultivated in pools, which would be built on the banks of the Paraguay river opposite Asuncion's botanical garden. The main advantage of using water hyacinths is their high growth rate, this being 100 to 500 g/day/m2 depending on environmental conditions, thereby allowing plant mass to double every 6 to 15 days. Additionally, carbon to nitrogen ratio in water hyacinth vegetal mass is optimum for biogas generation. About 6.4 kWh/m3 biogas calorific value is high enough to be used for producing heat and, therefore, for generating electricity in a thermal power plant. Such power plant could be directly connected to the national grid through the Puerto Botanic transformer station by building a 2 km long 220 kV transmission line crossing the Paraguay River. This project could save ANDE up to 25 million US$ every year due to reduced contracted power at the Itaipu power plant. Although this reduction will decline by 3% each year due to increased electricity demand, the investment of around 98 million US$ could be repaid within 15 years and would have 5% IRR and US$ 40.5 million NPV.
