Dezincification in cast and heat-treated alpha-beta brass samples
Authors: Biezma M. V. , Strobl S. , Linhardt P. , Ball G. , Haubner R. 
Published: September 2023

Abstract
Two α-β brass alloys with varying Zn contents have been studied. The samples received for examination were heat-treated at 500 °C in order to conduct dezincification studies according to EN ISO 6509-1 and to measure the depth of dezincification from metallographic sections.
According to the phase diagram, the α-phase content should increase as a result of heat-treatment at 500 °C. This phenomenon, however, is difficult to observe in the metallographic sections which were prepared from the heattreated samples. When analyzing the depth of dezincification, it was found that reduced dezincification occurred in the heat-treated samples. This is plausible since β brass is attacked by preferential corrosion.
Not only was uniform layer dezincification observed in the brass alloy with the higher Zn content, but also the onset of plug dezincification. This is associated with the original microstructure of the brass which is characterized by a coarse primary grain size. In this alloy, it is clearly observed that larger areas containing alpha brass will impede the process of dezincification.
Robotization of conventional electrolytic process in metallography

Abstract
Electrolytic polishing is a finishing method that removes material from a metal or alloy through an anodic dissolution process. Etching can often be performed in the same electrolyte by simply reducing the applied voltage to 10 percent of that required for polishing. Manufacturers of metallographic equipment present their products as automated. Only the electrolysis process itself is automated. After finishing, the sample must be immediately removed manually by the operator and cleaned. This process is critical with regard to the quality of the final sample surface and safety, because hazardous substances are often handled. The robot is placed next to an electrolytic equipment and handles all sample movements and the cleaning process in the ultrasonic bath in this experiment. The samples are made from ER308LSi austenitic stainless steel using 3D printing by Wire Arc Additive Manufacturing (WAAM). The final surface is achieved electrolytically on the commercial equipment. The aim of the experiment is to compare the microstructure, especially with regard to the possibility of distinguishing delta ferrite. The surface is characterized using various microscopic techniques. Robotization can be the key to improving surface quality and safety.

Department of Physical Education. Faculty of Sport Science. Semarang State University. Advisor Dr. Tri Rustiadi, M. Kes.
Keywords: Implementation, Scientific Approach, Physical Education
The background of this problem is based on the results of observations in Vocational Schools throughout Wonosobo District and school experience in one of the Vocational Schools in Wonosobo District, it was found that all schools have implemented the 2013 curriculum but the implementation of the 2013 curriculum scientific approach has not been implemented optimally. The purpose of this study is to determine the implementation of the scientific approach in learning planning, implementation of learning, and evaluation of Physical education learning in Vocational Schools throughout Wonosobo District.
The research method used by the researcher is descriptive qualitative. The objects in this study were 4 SMK in Wonosobo District that had implemented the 2013 curriculum. The subjects in this study were physical education teachers, class X students, and principals at SMK in Wonosobo District. The instrument of data collection was carried out by the methods of observation, interviews, and documentation. Data analysis was carried out using data reduction, data presentation and drawing conclusions. Test the validity of the data using triangulation of sources and techniques.
The results of the study can be concluded that, in planning the lesson the teacher has made a lesson plan using a scientific approach, but the teacher still has difficulty in adjusting the characteristics of students and the conditions of each school. In the implementation of learning using almost all teachers have carried out 5M activities (observing, asking, trying, reasoning, and communicating), but there are still two teachers who have not carried out reasoning and communicating activities in learning activities. Learning using a scientific approach is also not optimal because there are several things, such as the lack of feedback from students, the characteristics of students who are different, the condition of the infrastructure that has not been maximized in every school. Then the implementation of learning also has not used various media and learning resources, and some teachers still have not provided cooling activities to students.
Suggestions in this study is that teachers should improve the RPP according to Permendikbud No. 22 of 2016, the characteristics of students and the circumstances of each school. Then in the implementation of learning, the teacher must accourding to Perendikbud No. 22 of 2016.

The purpose of this study was to analyze reception movement skills in female athletes of SMK Pelita Nusantara 1 Semarang which were analyzed from the Reception technique using stick media so that they could improve reception movements to be more effective and efficient. Types of research using experiments. The sample was 18 female athletes of SMK Pelita Nusantara 1 Semarang who had the same reception skills, namely not yet mastering reception. The instrument used in this study was a reception test from Richard H. Cox. The results showed that (1) There was a significant effect of lower passing practice using a stick on the accuracy of lower passing for beginners, with a significance value of p 0.000 < 0.05. (2) There is a significant influence of the practice of bottom passing of the stick on the accuracy of the lower passing for beginners, with a significance value of p 0.000 < 0.05. (3) The practice of bottom passing without a stick is not significantly better than the practice of bottom passing with a stick against the accuracy of lower passing for beginners, although there is an average posttest difference of 2.33, greater, but not significantly different (sig p 0.129 > 0.05). The timing of passing the ball, the position of the hands, and the position of the body greatly affect the results of the lower power passing. With the development of the media, it can be a reference for athletes and coaches.

A man in his late 70s presented with one week of progressive chest and muscle pain, generalized weakness, and fatigue. He received a single infusion of pembrolizumab three weeks prior as adjuvant immunotherapy for stage IIb malignant melanoma after undergoing wide local surgical excision. He was started on steroids for pembrolizumab-induced myositis and myocarditis. Symptoms progressed to include severe dyspnea, dysphagia and eyelid ptosis requiring tracheostomy and PEG tube placement. Serologic studies ultimately confirmed myasthenia gravis and anti-SSA myositis.
He was emergently treated with plasma exchange, pyridostigmine, Intravenous Immunoglobulin (IVIG) and is making gradual improvement with physical therapy and oral prednisone taper.
We report a severe case of Pembrolizumab-induced triad of myasthenic crisis, myocarditis with myositis specific anti-SSA 52kD Ab IgG autoantibody for the first time. More studies are needed to assess the clinical significance and prognostic value of this autoantibody in patients presenting with Pembrolizumab-induced triad.
Intraneural ganglion cyst of the peroneal nerve at the lateral knee: A case report and literature review
Authors: Morena Jonathan , Yang Brian , Lee Steve , Paul Dustin , Leung Dora 
Published: September 2023

Introduction: Intraneural ganglion cysts can arise from the peroneal nerve at the lateral knee secondary to synovial fluid tracking along the articular branch and transforming within the nerve into a mucinous cyst, resulting in nerve compression.

Case Report: A 17-year-old right-handed male presented with a four-month history of right foot drop. He is physically active and attributed the foot drop to a sprained ankle. EMG/NCS showed a right common peroneal neuropathy distal to the innervation of the biceps femoris short head with active denervation. MRI showed an intraneural ganglion cyst in the common peroneal nerve starting at the level of biceps femoris. On exam, he had right foot drop and sensory deficits referable to the peroneal distribution, along with a right steppage gait. He had successful decompression of the ganglion cyst, excision of the articular branch and resection of the proximal tibiofibular joint, with clinical improvement.

Conclusion: Early recognition and surgical treatment leads to better outcomes for patients when an intraneural ganglion cyst results in neurologic deficits. Physical activities and trauma, which increase stress on the knee joints, may predispose ganglion cyst formation within peroneal nerves. Fibers of the deep peroneal nerve may be preferentially affected when compared to the superficial peroneal nerve. Disconnection of the articular branch and proximal tibiofibular joint resection may decrease risk of recurrence.
Clinical Outcomes in COVID-19 patients with pre-existing myasthenia gravis:
Authors: Daif Ahmed , Gapchup Tejal , Paul Pritikanta 
Published: September 2023

INTRODUCTION: Myasthenia gravis (MG) presents an additional challenge in managing COVID-19 as outcomes potentially depend on prior disease control and treatment. Yet the role of pre-existing MG in COVID-19 outcomes has not been established.
METHODS: We searched PubMed, Scopus, and Web of Science databases for reports of MG patients with confirmed COVID-19 until March 2022. We analyzed data on patient demographics, chronicity, and MG control at baseline pre-COVID, treatment history and outcome following COVID infection.
RESULTS: Twenty-nine publications with 119 patients (females n=75, age range 20-93 years, AChR Ab positive n= 65, MuSK Ab positive n= 5, seronegative n=14, unknown n=35) were included. Eighty-three (70%) were hospitalized, more than half with MG exacerbation. There was no significant difference in disease duration or control of MG symptoms at baseline between hospitalized and non-hospitalized. Hospitalization was associated with higher dose of daily prednisone but a comparable proportion of patients were on steroid-sparing agents. Among hospitalized patients, 40% were intubated uncorrelated with MG baseline control. Unfavorable outcome was not always associated with MG exacerbation. Amongst those discharged,75% received intravenous immunoglobulin (IVIG) or Plasmapheresis (PLEX) for MG exacerbation as compared to 67% with a fatal outcome didn’t receive either.
CONCLUSION: Preexisting MG does not appear to be associated with severe COVID-19 outcomes. Higher dose of prednisone prior to COVID-19 infection is associated with increased risk of hospitalization but MG control at baseline did not determine worse outcome. IVIG/PLEX appears safe and potentially can reduce fatality in patients with COVID-19 experiencing MG exacerbation.

Esta investigación tiene por objetivo determinar la calidad de la atención percibida por los pacientes y el nivel de estrés laboral en el personal de salud en el Centro de Salud Materno Infantil “Wichanzao” – La Esperanza. Según la metodología cualitativa, para la recolección de datos se emplearon dos test, bajo la técnica de encuesta: el Test de Hamilton y la Encuesta de Satisfacción de Usuario del Sistema de Salud, aplicados a 80 trabajadores de salud y a 360 pacientes, respectivamente. Se encontró que el 78,8% del personal de salud presenta momentos de mal humor y el 56,3% de ellos, mala calidad de sueño. Ello implica que un importante porcentaje de pacientes (45%) perciba la calidad de la atención en dicho establecimiento como “regular”. Finalmente, se concluyó que a mayores niveles de estrés experimentado en los trabajadores del sector salud, menores niveles de satisfacción, y por ende, menor calidad percibida por los pacientes respecto a la atención recibida.

Education, Experience, and Exchange: The Hull House Women, an International Network, and Chicago’s Immigrant Population
Authors: Bailey Cheylan Alice 
Published: September 2023

This paper explores the creation and purpose of Chicago’s Hull House. It provides an overview of volunteer work by women in the US and addresses the European influence on Jane Addams’s idea for Hull House and the various educational aspects and approaches used by the Hull House educators.
Founded, funded, and administered by women, the Hull House settlement is shown as a prime example of the nascent spirit of American volunteerism that epitomized that era. Women were able to participate in the settlement because of the evolving perception of their role in society. It was possible to devote one’s life to charity and not to marriage and child-raising. The force of the Hull House residents was to combine their individual skills and strengths to work as a united group of very dynamic and talented women. Education, experience, and exchange were the three pillars of their very successful settlement home. In their efforts to reform and better the living conditions in the rundown Chicago neighborhood, the Hull House women became involved in politics and policymaking. Thereby, they began to have a voice which became louder and louder and could not be silenced.
The “Thingness” of the American Middlebrow:
Authors: Lanneau Hannah Grace 
Published: September 2023

In this paper, I examine the ways in which Anita Loos’s Gentlemen Prefer Blondes and F. Scott Fitzgerald’s The Great Gatsby both critique and engage with materialism and consumerism as middlebrow texts. Bill Brown’s discussion of the power and meaning of “things” of literature (2003; 16-17) serves as a framework through which I analyze the double “thingness” of the middlebrow as depicted in these novels—that is, the simultaneous investment in and critique of consumer objects. To that end, I analyze both the print culture histories and content of Blondes (which is widely considered a middlebrow text in academic scholarship) in conversation with Gatsby (which is not always thought of as a middlebrow text). I argue that, rather than view middlebrow within a high/low brow paradigm, we should instead consider the ways in which the middlebrow operates with and within mass consumer culture as well as provides a critique of that culture. Because the American middlebrow has a distinct socioeconomic history, I demonstrate how these novels also grapple with the “thingness” of American identity and the Americanness of “things” by centering the protagonists’ engagement with material objects in the construction of their identities. Gatsby and Blondes demonstrate the middlebrow American quality of things through their narrative content, and the novels’ histories as print objects reflect their circulation as commercial things themselves.
This article challenges understandings of the “middlebrow” as a genre unto itself by examining the historical situatedness of the term and its evolving definitions. This article also invites renewed conversation around the middlebrow by proposing a new perspective and an alternative approach to the understanding of middlebrow literature. I argue that these novels present an ideal re-entry into discussion of the middlebrow because of their disparate print culture histories and the cultural capital (or lack thereof) they signify in the present day. This article thus traces the print histories of these two novels alongside analyses of their reception histories and critiques the concept of a middlebrow literature, turning again to contradictory definitions of the term to suggest a more fluid understanding of the middlebrow in scholarship should be able to account both for the continuing appeal of early twentieth-century middlebrow literature and the ways in which the middlebrow itself as an aspirational aesthetic and consumerist ethic has evolved and is ubiquitous in the twenty-first century.
