Innovative Metal Powder Production Using CFD with Convergent-Divergent Nozzles in Wire Arc Atomization
Authors: Sukkee Matee , Kongphan Phanphong 
Published: October 2024

This study aims to enhance the production of metal powders using a novel approach that integrates computational fluid dynamics (CFD) with convergent-divergent (C-D) nozzles in wire arc spraying atomization (WASA). The primary objective is to investigate the influence of nozzle design on particle size distribution and production efficiency. Utilizing the ANSYS CFD Fluent program, simulations were conducted to analyze the effects of various parameters, including throat diameter and divergent angles, on gas dynamics and metal droplet behavior. The findings reveal that C-D nozzles facilitate the acceleration of gas flow to supersonic speeds, significantly improving the shear force acting on the molten metal, thereby promoting the fragmentation of droplets into smaller particles. Notably, the optimized nozzle configuration achieved a median particle size (D50) of 44.42 µm, suitable for additive manufacturing applications. The novelty of this work lies in its comprehensive simulation framework that allows for rapid virtual testing, potentially leading to significant improvements in the efficiency and quality of metal powder production processes. This research addresses critical gaps in the existing literature and provides a robust foundation for future studies in the field of metal powder manufacturing.

Published: October 2024

The process of formulating the basic strategies in a construction project must go through a set of stages. The desired objectives in feasibility studies should be highlighted to ensure that the packages of the infrastructure projects are moving smoothly in terms of the desired goal. In order to meet ambition for the long term in infrastructure projects, it is required to adopt the five pillars of SMART for rectifying the paths of feasibility studies. The study is a summarizing of fifteen elements that could have negative impacts on outputs of feasibility studies. The designed questionnaires have already been distributed via two stages to the experts/consultants in project management and others. 63 questionnaires were collected to find the negative impact of the elements, and the second stage included 89 participants for measuring their responses about the extent to which previous studies that were prepared over the past five years matched the concept of SMART-objectives. Based on the theoretical principle through analyzing the responses/opinions of participating experts, it was found that the feasibility studies for infrastructure projects obtained the following percentages: 46.07%, 41.57%, 28.09%, 22.47%, and 22.47%. This reflects that the objectives of the infrastructure project were specific, measured, achievable, relevant, and Time-Bound) in sequence consistent with the mentioned percentages. For the improvement outcomes of feasibility studies for infrastructure projects, that required a clear and invaluable link among all feasibility studies and the concept of applying the SMART-five pillars.

Authors: Paudel Deliya , Regmi Himanshu 
Published: October 2024

Background: Abnormal uterine bleeding is one of the most common problems among pre and postmenopausal women. Abnormal uterine bleeding is diagnosed when there is a substantial change in frequency, duration, or amountof bleeding during or between periodsin the absence of any organic pathology. The study was perform to assess the endometrial causes of abnormal uterine bleeding and their incidence in different age groups.
Materials and methods: It was a cross sectional and descriptive study carried out at a Manmohan medical College & hospital, over a period of two year from 13th April, 2020 to 15th March, 2022. In the study all the endometrial tissue either obtained by endometrial curettage and biopsy or hysterectomy presenting with abnormal uterine bleeding for more than 3 months were included
Results: A total of 88 cases were received during this period, out of which there were 78 endometrial tissue samples and 10 hysterectomy specimens. The patient’s age ranged from 20 years to 73years. The pattern of endometrial biopsy are Proliferative (37.5%) and secretory (20.45%) phase endometrium is the most common pattern seen, followed by disordered proliferative endometrium (13.63%), endometrial hyperplasia without atypia (9.09%), Change consistent with Exogenous Hormone (5.68%), Chronic Endometritis (5.68%), Endometrial Polyp(3.40%), Endometrial Hyperplasia with Atypia(2.27%) and Endometrial Carcinoma (2.27%).
Conclusions: Patients with abnormal uterine bleeding show a varying spectrum of endometrial pattern. Cyclic endometrium is commonly seen in the reproductive age group whereas hyperplasia and carcinomas are seen in pre/postmenopausal age group. Endometrial biopsy with histopathological examination is a major diagnostic tool in the evaluation of abnormal uterine bleeding.

Authors: Mainali Nirajan , Acharya Barsha , Phulara Ganesh 
Published: October 2024

Background: The spectrum of renal diseases varies with different ethnic populations, geographical locations and environmental factors. In children, many signs of kidney disease are either hidden or mimic other systemic diseases. There is a need of identifying renal disorders at an early stage to retard the rapid progression. This study aims to identify the different histopathological spectrum of glomerular diseases in pediatric renal biopsies.
Materials and Methods: This was a cross-sectional prospective study undertaken at the Pathology Department at Pratham Pathology Laboratory, Lazimpat for 17 months duration (May 1ST - December 31ST 2023). The final diagnosis was made by a pathologist after correlating the histopathological findings with immunofluorescence and other clinical and laboratory findings.
Results: A total of 97 pediatric patients’ renal biopsy specimens were evaluated. Patients’ age ranged from 0-16 years. The majority of patients were in the age group of 11-16 years (62.8%). The study showed slight female predominance with male to female ratio of 0.8:1. The most common glomerular disease was Lupus Nephritis with a frequency of 19 (19.6%). The most common cause for Rapid progressive Glomerulonephritis in the pediatric population was Post Infectious Glomerulonephritis with a frequency of 5 (50%).
Conclusions: The most commonly diagnosed glomerular disease in pediatric renal biopsies was Lupus Nephritis. The leading cause of Rapid Progressive Glomerulonephritis was Post Infectious Glomerulonephritis and Lupus was one of the leading causes of chronic kidney disease.
Direct immunofluorescence in bullous disorders: A mini-review
Authors: Pant Anil Dev 
Published: October 2024

Background: Immunofluorescence microscopy is an invaluable tool for different lesions in dermatopathology. These lesions include bullous lesions, vasculitis, and connective tissue disorders/systemic lupus erythematosus. In this review, we take a look at bullous disorders.
Some of these diagnoses are not possible on routine histopathology alone and require immunofluorescence for confirmation. Different diseases can be diagnosed according to the immunoglobulins/complements, sites of deposition (dermo-epidermal / intercellular spaces / dermal), and their patterns (linear, granular). Knowing the exact type of lesion can help guide treatment accordingly.
The Schnorrer in Israel Zangwill's Work
Authors: Labrande Mélisande 
Published: October 2024

Abstract
This article charts the historical and literary origins of the schnorrer, a Yiddish term for ‘proud beggar’ and a character of Eastern European Jewish culture. It aims to shed light on the schnorrer's entrance as a protagonist in British popular literature in the work of Israel Zangwill, and to show its originality. To do so, it focuses mainly on the novella The King of Schnorrers (1894), in which the schnorrer holds the leading role, and on Children of the Ghetto (1892), in which the schnorrer is a secondary and yet essential character. By locating the schnorrer outside of the Ashkenazi ethno-social context, Zangwill carries out a refashioning of this figure and grounds him in a wider social and literary lineage. He turns him into a literary character who challenges Western capitalist societies, thanks to a multi-layered identity, conflicting contexts and plural literary genres.
Amalgamation and Regeneration
Authors: Feldt Jakob Egholm 
Published: October 2024

Abstract
This article discusses Israel Zangwill's play The Melting Pot (1908) and Horace M. Kallen's essay ‘Democracy versus the Melting Pot’ (1915) as two different visions of future Jewish inclusion. Zangwill's play and Kallen's response reflect social changes at the time, and both visions consider Jewish history exemplary for the world-to-come. Both show how conceptions of Jewishness were turned into universalist teleologies, but of different kinds. Zangwill's play opened in Washington at the height of immigration, urbanisation and social change, and it swiftly exemplified a vision of the American nation in the making, emphasising concepts of amalgamation more than old historical identities. In opposition, Kallen's response in 1915 emphasised historical identities and rejected the metal melting metaphors, replacing them with a Darwin-inspired spontaneous ‘symphony’. Zangwill and Kallen both imagined the future world as profoundly shaped by Jewishness, albeit with different consequences.
Turning Sour into Sweet, Darkness into Light
Authors: Kaplan Dana Evan 
Published: October 2024

Abstract
9½ Mystics: The Kabbala Today by Rabbi Herbert Weiner introduced the idea of mystical search to a generation of American Jews who were turned off by traditional synagogue Judaism and unsure of how to relate to the emerging counterculture. He met with a number of mystics to find out if their life-secrets can have meaning even for those who do not share the full intensity of their experience. Weiner's search relied in large part on Gershom Scholem's idea that there was a dramatic contrast between rabbinic Judaism and Kabbalistic Judaism. Kabbalah was like an underground stream moving through the heart of Judaism, bringing with it transformative mythic ideas, providing inspiration and spiritual excitement. Weiner's book successfully popularised Scholem's theories of what Kabbalah was, as well as the mystical thought of previously unknown mystics such as Rav Kook. 9½ Mystics transformed the American Jewish religious landscape, especially in the Reform movement.
A Tribute to Professor Leon Yudkin (1939–2013)
Authors: Herman David 
Published: October 2024

Abstract
This is a tribute to the Jewish literary critic Professor Leon Yudkin, who died in 2013. He was a prolific writer: the author of more than a dozen works and editor and co-editor of another five books. The range of his interests was prodigious, from individual writers like Shmuel Agnon, Joseph Roth and Else Lasker-Schüler to the Prague Circle, French feminist writers, German Expressionism and, above all, a series of authoritative surveys of Hebrew, Yiddish and Israeli literature. Much of this article focuses on his last book, posthumously published, Fiction Derailed: Form for the Modern (2020), an exploration of the modern novel. His greatest legacy was as a pioneer, someone who opened up the study of Jewish and especially Hebrew and Yiddish literature in the academy.
