Published: March 2024

Armour steel products developed in various forms, function and materials. The usage of steel as bulletproof material has many advantages i.e. easy to transport, easy to be formed and has competitive price compared to other material. The mechanical properties of steel which can be used as bulletproof material must meet certain criteria which can be improved through heat treatment process. The aim of this research is to determine the most suitable heat treatment parameter of SKD 11 modified steel material to improve its hardness and the effect of thickness SKD 11 modified as requirement for bulletproof material. This research processed the SKD 11 modified steel material using heat treatment with 1030°C quenching parameter with 3 hours holding time followed by tempering temperature parameter which vary of 400°C, 500°C, 530°C and 600°C with 4 hours holding time for each tempering. The tempering process is done twice for each sample. Result showed that the highest hardness properties was achieved at 1030°C quenching parameter with 3 hours holding time followed by tempering temperature parameter of 530°C with 4 hours holding time. From the best parameter resulted in highest hardness then SKD 11 modified material for ballistic test varied into 5, 7.5 and 10 mm thickness. TheBallistic performance test level III and level IV showed that hardened SKD 11 modified steel material with 10 mm thickness has the lowest BFS value of 3.32 mm and 7.54 mm with a shattered phenomenon present on the experiment. The experiment result confirm that the SKD 11 modified material meet the BFS allowed limit which 46 mm based on NIJ0101.06 standard.

Published: March 2024

This study investigated forming beads of an AlCrFeCoNi high entropy alloy (HEA) using the multi-beam laser directed energy deposition (L-DED). The X-ray diffraction (XRD) and electron backscatter diffraction (EBSD) analyses confirmed the formation of a single phase composed of the AlCrFeCoNi HEA with the body-centered cubic (BCC) structure. Various laser powers (80W, 100W, and 120W) were examined to understand their effects on bead formation and bonding between the formed bead and substrate. At 80W, weak bonding was observed with a gap between the bead and substrate as the laser melted only the AlCrFeCoNi HEA powder. Increased laser power strengthened the bonding, but altered the HEA composition, deviating from the equiatomic compositions. Furthermore, the study revealed a correlation between laser power and grain size. With increasing laser power, microstructures with coarser grains were obtained.

Published: March 2024

The wear failure is widely found in steel bars used for coal screener machines in the mining industries. The failed parts of such components require immediate replacement to lengthen the machine's service life. This work aimed to investigate the structure and properties of the worn bar of a screener machine after experiencing wear failure and analyze the wear mechanism. The work started by machining the sample from the original bar, then grinding and polishing. The microstructure of the worn samples was observed using SEM and XRD. The hardness distribution of the bar was measured from the periphery to the core. The results of this work would provide evidence of wear sources responsible for the wear failure.
The Effect of Graphene Oxide (GO) on Mechanical Properties of Fly Ash-Based Geopolymer-GO Composites
Authors: Susanto Agus , Haris Abdul , Saleh Muhammad
Published: March 2024

This work deals with the effect of adding GO on the mechanical properties of fly ash-based geopolymer-GO composites. Compressive strength, water absorption, density, and flexural strength tests were carried out to investigate mechanical and physical properties of fly ash-based geopolymer-GO composites. The results showed that the addition of graphene oxide into fly ash-based geopolymer-GO composites up to threshold value (i.e., in this study, 1 gram or 1.1 wt.%) will decrease total porosity as well as a change in the total quantity of pores and their distribution due to densification of bulk matrix of the specimens. Consequently, it reduced water absorption, increased the density of the specimens, and subsequently increased mechanical properties (i.e., compressive strength and flexural strength). Conversely, the addition of graphene oxide into fly ash-based geopolymer-GO composites greater than above the threshold value will increase total porosity due to coarsening of bulk matrix of the specimens and subsequently increased water absorption and reduced density of the material. As a result, it decreased the mechanical properties (i.e., compressive strength and flexural strength) of fly ash-based geopolymer-GO composites. The present research demonstrates how graphene oxide can improve the mechanical properties of fly ash-based geopolymer-GO composites to a certain extent, which may match with industrial applications.
Navigating the diagnostic and therapeutic complexities of autoimmune encephalitis
Authors: Chang Thashi
Published: March 2024

Characterized by immune-mediated inflammation of the brain, autoimmune encephalitis (AE) encompasses a diverse array of disorders, each presenting with unique as well as overlapping clinical manifestations, and underlying autoantibodies targeting neuronal and glial surface antigens. The clinical spectrum can range from subtle cognitive and behavioural changes to severe seizures, movement disorders, and altered consciousness. However, what truly sets AE apart from other encephalitides is its potential reversibilitywhen identified early and managed appropriately. The identification of N-methyl-D-aspartate receptor (NMDAR) antibody encephalitis in 2007 heralded the discovery of a spectrum of immunotherapy-responsive AE. However, misdiagnosis remains prevalent despite diagnostic algorithms, resulting in unnecessary immunotherapies and delayed treatment of the correct diagnosis. AE diagnosis requires a judicious blend of diagnostic algorithms, antibody testing, and clinical acumen. Testing for antibodies against neuronal surface antigens, preferably in cerebrospinal fluid, is essential, but should be contextual to clinical relevance.Treatment guidelines are largely based on retrospective studies due to a dearth of randomized and prospective data. However, early immunotherapy initiation has proven to be pivotal for optimal outcomes. The therapeutic landscape in AE continues to evolve with the introduction of novel targeted immunotherapies.This review highlights the complexities, and proposes a systematic approach, to the diagnosis and treatment of AE.

Introduction: Neurophysiological testing is a valuable tool in the diagnosis of Guillain-Barre syndrome (GBS). Sural sparing is a usual feature of acute inflammatory demyelinating polyneuropathy (AIDP) type GBS. However, sural involvement has been reported in later stages of GBS. It is important to identify patterns of sural nerve involvement to differentiate GBS from its mimickers and to stage the disease. This research aimed to detect the pattern of sural nerve involvement in AIDP-GBS cases with normal electrophysiological responses in the sural nerve at the beginning.Objectives: To determine the location and timing of sural nerve involvement in AIDP-GBS.Methods: This prospective follow up study included diagnosed cases of AIDP-GBS with preserved bilateral sural responses. Nerve conduction and somatosensory evoked potentials (SSEP) were done on admission and weekly thereafter for four consecutive weeks. The last evaluation was done four weeks after the fourth study.Results: All patients (100%) showed normal distal sural responses over the initial four weeks of follow up. They continued to remain normal up to eight weeks in eight patients (53.3%). Two patients had gradual prolongation of their sural SSEP on consecutive studies. One of them had gradual reduction of sural sensory nerve action potential and nerve conduction velocity along with the prolongation of sural SSEP latencies. The difference of SSEP latency increments in the left sural nerve of these two patients was statistically significant (p<0.05). The right sural SSEP latency difference was not significant.Conclusion: Sparing of the distal sural sensory response was demonstrated in 100% of AIDP-GBS cases during the first four weeks of follow up. More than 50% of the cohort demonstrated preserved sural sensory responses for eight weeks from the initial presentation. Two out of fifteen patients showed statistically significant proximal sural sensory pathway involvement with increasing SSEP latencies. This finding suggests that in some patients, the sural sensory pathway may get affected at its proximal segments or at the central nervous system before the distal nerve is affected.

Published: March 2024

Introduction: Ureteral stents require materials that balance bulk and surface properties. Achieving both can be challenging, as ideal bulk properties may not align with optimal surface properties. Thus, researching coatings and biomanufacturing methods for ideal materials is essential. Methods: A systematic review and meta-analysis, following PRISMA Guidelines, involved literature searches across five databases: PubMed, Scopus, Embase, ClinicalKey, and Cochrane. From 417 screened articles, eight studies were deemed eligible for qualitative and quantitative analysis. The selected articles underwent bias assessment using ROB Tools 2. Results: The systematic review analyzed 1.356 participants. Findings revealed that firm ureteral stents significantly increased risk of infection, hematuria, and lower body pain. On the contrary, soft stents reduced infection (OR: 0.62; p=0.004), hematuria (OR: 0.60; p<0.001), and lower body pain (OR: 0.63; p=0.0002). However, infection reduction effect was uncertain due to heterogeneity. Coated vs non-coated material analysis found no difference in encrustation (OR: 1.26; p=0.52) or infection (OR: 1.67; p=0.99). Stent firmness did not affect encrustation on double J stent (OR: 0.97; p=0.17).Conclusions: Softer materials like silicone are preferred for ureteral stents to reduce symptoms like hematuria and lower body pain. Coatings like silver nanoparticles and triclosan, while enhancing antimicrobial properties, did not effectively lower infection risk.

Purpose: The aim of this experimental study is to investigate the correlation between the presence of senescent cells and the tumor size, the lymphovascular invasion (LVI), the invasion of rete testis (RTI), the preoperative tumor markers or pathological stage in patients who underwent orchiectomy for malignant purposes. Methods: This experimental study included patients with a history of radical orchiectomy performed from January 2011 to January 2019. The testicular tissue specimens underwent an immunohistopathological process for the detection of the presence of cellular senescence. Besides, the tumor size, the histopathological type, the pathological stage of the tumor and the presence of Lymphovascular (LVI) or rete testis (RTI) invasions were also recorded. Additionally, the preoperative serum levels of alpha-fetoprotein, beta-human chorionic gonadotropin and lactate dehydrogenase were recorded. After the completion of immunohistochemical analysis, the rate of senescent cells in each specimen was also recorded. Results: The mean senescent cell rate was estimated to be 14.11±11.32% and 15.46±10.58% in patients with presence of LVI or absence of LVI, respectively (p=0.46). The mean senescent cell rate was calculated at 18.13±12.26% and 12.56±9.38% (p=0.096) in patients with presence of RTI or absence of RTI, respectively. The mean senescent cell rate in the pT1 group was calculated at 14.58 ± 9.82%, while in T2 and T3 groups the mean senescent cell rate was estimated to be 15.22 ± 12.03% and 15.35 ± 14.21%, respectively (p=0.98). A statistically significant correlation was detected between the senescence rate and the tumor size (Pearson score 0.40, p=0.027) and between the rate of senescent cells and the preoperative level of lactate dehydrogenase (LDH) (Pearson score -0.53, p=0.002).Conclusions: The presence of cellular senescence was correlated with the extent of the testicular tumor in terms of tumor size as well as the preoperative level of the LDH serum marker.
Time performance of scoop stretcher versus vacuum mattress for prehospital spinal stabilization: open-label simulation-based randomized controlled trial
Authors: Stuby Loric , Thurre David
Published: March 2024

Recent research has yielded conflicting results on the use of spinal stabilization in prehospital care, with some guidelines expressing concerns about its potential lack of benefit or harm. Transportation on a backboard can cause pain, discomfort, and pressure ulcers, whereas the log-roll technique can cause unnecessary movement and aggravate existing injuries. The scoop stretcher and vacuum mattress provide comparable or better immobilization and comfort than the backboard. Prehospital time is critical, and patients with life-threatening conditions should undergo rapid stabilization procedures. Despite this, some studies have overlooked the scoop stretcher as a spinal stabilization device. The primary goal was to compare the time required to achieve spinal stabilization using a scoop stretcher versus a vacuum mattress. This was a monocentric, parallel, randomized (sealed envelope), superiority, open-label, controlled simulation experiment. All student paramedics, registered paramedics, and EMTs who work in the participating EMS were eligible to participate in the study apart of the study team. The experimental group had to use a scoop stretcher, whereas the control group used a vacuum mattress. Fifteen participants were included. The scoop stretcher group required less time to complete the stabilization procedure (median [Q1; Q3]: 127 seconds [111;145] versus 212 [156;237], p=0.005). Using a scoop stretcher for spinal stabilization is more time-efficient than a vacuum mattress, making it a viable option for unstable trauma patients in the prehospital setting. More research is needed to determine its efficacy in actual clinical practice.
Role of Ayurveda in the Management of Becker Muscular Dystrophy: A Case Study
Authors: Bohra Mohita
Published: March 2024

Muscular dystrophies are a group of genetic disorders that lead to a gradual weakening of muscles, resulting in increased disability over time. Becker muscular dystrophy (BMD) is one such condition and is inherited through an X-linked recessive pattern, primarily affecting males. Symptoms of BMD typically begin in the teenage years or late twenties. Initial signs may include muscle cramps during exercise and reduced stamina. Over time, there is a gradual loss of muscle bulk in the hips, pelvis, thighs, and shoulders, often leading to a tendency to walk on toes. In Ayurveda, the factors contributing to this disease are believed to be an aggravation of Vata (one of the three doshas), depletion of Mamsa (muscle tissue), and Meda (fat tissue), impaired digestive fire, and blockage of functional channels (Srotorodha). The present case involved a 15-year-old male with weakness in both lower limbs for 4 years, a decrease in muscle mass around the pelvic and thigh area for 3 years, and an increase in calf muscle size for 3 years. The patient exhibited pseudohypertrophy in both calf muscles and positive Gower’s sign, along with a positive family history and elevated creatine phosphokinase levels, leading to a diagnosis of BMD. The treatment approach incorporated Panchakarma therapies and internal Ayurvedic formulations in line with the management of Sarvang Vata disorder. The treatment was administered in four sessions, with a 3-month gap between each therapy session. After a year of treatment, there was not only a halt in the progression of the disease but also a notable improvement in lower limb strength, which increased from 4 to 4+. In addition, there was an increase in proximal muscle mass, from 12.5 inches to 13 inches, and a reduction in calf muscle size and tightness. This promising outcome suggests the potential for managing the disease using Ayurvedic principles and therapies.

Published: March 2024

Orbital cavernous hemangioma is the most common benign vascular tumor of the orbit. They are gradually developing, painless tumors causing most frequently axial proptosis. It comprises a compact, tough, fibrous capsule covering a thrombosed, and septate venous convolution. The two main imaging techniques advised are magnetic resonance imaging (MRI) and computed tomography (CT), with the preference for MRI as it minimizes radiation exposure. We report a case of a 21-year-old female presented with protrusion of the left eye for 1 year. Examination revealed 6/6 vision in both eyes on Snellen’s chart. Color vision, contrast sensitivity, and visual fields were normal. The patient exhibited axial proptosis. On contrast-enhanced CT of orbit and contrast-enhanced MRI of the brain and orbit, she was found to have mass in the retrobulbar intraconal region. Surgical excision is the treatment of choice in symptomatic patients. A multidisciplinary team, including the ophthalmology and neurosurgery departments, performed the surgery. With careful dissection complete excision of the lesion was done. The postoperative vision was 6/6 in both eyes. Lid edema, ptosis, and limitation of extraocular movements were resolved in subsequent follow-ups. There was resolution of the proptosis with a good visual outcome. This report emphasizes the need for prompt surgical intervention with complete removal of the tumor to prevent recurrence and bleeding.
Practical aspects of color vision deficiency
Authors: Angrish Shreya , Chaudhary Apoorva
Published: March 2024

Color vision deficiency (CVD) is a nontreatable medical condition that can inflict issues in an individual’s life in every aspect. People who have CVD struggle in daily life, in early learning and development, in school, when choosing a career, and in their performance at work. A brief understanding of the neurophysiology of color vision, its pathology, and the ramifications of CVD in people’s lives including psychosocial effects can bring enough awareness in the community to deal with the issue at hand. The practical and medicolegal aspects of CVD also need to be discussed as the scarcity of such studies and cognizance among the public pose problems and confusion in society, which needs to be rectified.

Published: March 2024

Apert syndrome (AS) is a form of acrocephalosyndactyly, which is characterized by craniosynostosis, midfacial hypoplasia, and symmetrical syndactyly of the hands and feet. A 3-year-old female with craniosynostosis, high-arched palate, syndactyly, strabismus, and diagnosed as a case of Apert syndrome was brought to the outpatient department. Strabismus evaluation revealed 35 prism diopters of left convergent squint. Magnetic resonance imaging of the brain and orbit revealed hypoplastic extraocular muscles. A plan to carry out a bilateral medial rectus recession was made. However, intraoperatively, normal-sized muscles were found and the plan was modified to carry out only a left eye medial rectus recession of 5.5 mm. The patient was orthophoric postoperatively, indicating the unusual postoperative outcome in such a case. This report aimed to underline the challenges of managing a case of strabismus and the variable postoperative outcomes encountered in a case of Apert syndrome.
Medea Rejuvenates Herself: Female Roles and the Use of the Body in Seneca’s Medea
Authors: Csepregi Ildikó
Published: March 2024

The aim of this paper is to illustrate the arc of the sequence of events through which Medea rejuvenates herself – as she has rejuvenated others before her, she does it as if she were simply disassembling herself and putting herself in her own cauldron to be reborn as her younger and stronger self. After describing the different and changing female roles of Seneca’s Medea, the paper gives a close reading of the text to show how Seneca uses images of the body and to underscore the way Medea uses her own body to achieve her transformation: to start a new life by returning to her earlier self, i.e., by rejuvenating herself. To back this argument, the paper also highlights her previous acts of rejuvenation in textual and pictorial testimonies and argues that Seneca presented Medea as a rather positive figure, a deity, a magician, a healer, who is capable of ruling over life and death.
Julian the Apostate, Claudius Mamertinus, and Ammianus Marcellinus: Filling in a “Blank Spot”?
Authors: Pobežin Gregor
Published: March 2024

Flavius Claudius Julianus, often referred to as “Julian the Apostate,” ruled the Roman Empire from early 360 AD until his death in battle on June 26th, 363 AD. Despite his brief reign, Julian undertook sig­nificant reforms targeting various aspects of public life, including the administration and provincial governance. This paper focuses on his administrative activities in Illyricum, where he resided in 361 AD while campaigning against Constantius II. While facing immediate tactical concerns during his campaign, Julian reportedly engaged in imperial administrative duties within Illyricum, as documented by historian Ammianus Marcellinus and panegyrist Claudius Mamertinus. This research delves into Ammianus’ account to analyze Julian’s adminis­trative acts in Illyricum and subsequently across the Roman Empire.
The Motif of Freedom, Human Dignity, and Awareness of a Common Human Destiny between Antiquity and Cervantes
Authors: Tomc Bojana
Published: March 2024

The legacy of antiquity forms a constituent part of Cervantes’ opus. The vicinity of the classical imaginarium, with which Cervantes became acquainted during his education and while living in Italy, is represented by classical elements, topics, and motifs. Through these, he establishes a constant dialogue with antiquity. However, the humanistic note in his opus is most noticeable in his constant defense of freedom and human dignity and the value of the human being, reflecting the Renaissance concept of the human person. Freedom becomes a key element and cornerstone of Cervantes’ poetics, linking to the Renaissance tradition. Cervantes frequently expresses the premise of human freedom and its fundamental value. This pro­nounced orientation toward freedom may be related to his personal experience and explained by his painful captivity in Algeria, where he spent five years. He started to write to survive and maintain clarity of mind and spirit.
An Ethiopian “Renaissance” Queen? Mentewab as Protector of Arts and Patron of Iconography
Authors: Steyn Raita
Published: March 2024

In Ethiopia, the period from the late 16th and 17th Centuries has caused a controversy because some consider this period as Ethiopia’s recovery from religious, civil conflicts as well as sectarian discord, while others including Kofi Darkwah (1975), define it as a continued descent prosses for the empire. In line with this disagreement, factual information can speak for itself in the course of this study. Emperor Susenyos (1572-1632 CE) was a strong supporter of Catholicism, yet his son, Fasilidas (1603-1667 CE) as his successor, reinstated Ethiopian miaphysite Orthodoxy. The establishment of Gondar as the permanent capital in 1636, is an event heralded by Henze (2000) as the onset of an Ethiopian Renaissance, particularly in artistic, architectural, and musical domains. After Fasilidas’s demise, his son, Yohannes I reigned from 1632-67 CE. Yet, it was Fasilidas’s grandson, Iyasu I the Great (r. 1682-1706 CE), who distinguished himself through extensive architectural projects, notably transforming Gondar into a captivating city. Iyasu I’s assassination caused significant turmoil in Gondar, subsequently resulting in a gradual loss of political power. When Iyasu I’s son, Bakaffa (r. 1721-1730 CE) ascended to the imperial throne, the arts - namely, chant (zema), poetry (qene), interpretation (tergum) and refinement of the court minstrels’ music had already been supported and vigorously promoted. However, it was Bakaffa’s wife and later widow, Mentewab (1706-1773 CE), who emerged as the pivotal figure in this Ethiopian “Renaissance”. Additionally, the diverse styles of Ethiopian iconography sponsored by Mentewab, some adorned with elements reminiscent of the decorative style of the Rococo period, illustrate the queen’s remarkable aesthetic standards.

The research on Mentewab, also known as Welete Giyorgis, has been guided by portrayals in iconographies, chronicles, paintings, testimonials from church builders and castles, and indirectly by information provided in texts such as Kebre Negast, and Fetha Nagast. To this end, special attention has been drawn on Mentewab’s legacy as the founder, protector, and patron of the Ethiopian Orthodox Tewahedo Church Narga Selassie, renowned for its resplendent Qwara style that fused European, Islamic, and Indian elements while retaining strong Ethiopian traits. With special attention to the iconographic representations of Queen Mentewab as the ktetor of Narga Selassie Church, the study explores symbolic significances embedded within relevant creations and artistic styles. By contextualising them within their historical framework, this analysis explores Mentewab’s influence on her contemporary politics, religion, art, and literature in Ethiopia.

Introduction: Environmental physical therapy (EPT) is the incorporation of environmental health into the field of physical therapy that encompasses the relationships between the environment, human health and functioning, and physical therapy. This study determined the level of awareness and understanding of Filipino physical therapists regarding the general concepts of EPT, their perceptions regarding its barriers and facilitators, and the current clinical practices in the Philippines.

Methods: This study employed a quantitative design. Subjects were Filipino clinical physical therapists with at least 3 years of clinical practice in the Philippines. A questionnaire containing 55 items was developed, validated, and pre-tested. Data analysis was done using descriptive statistical analysis.

Results: Eighty-eight clinical physical therapists participated in the study. Final questionnaire consisted of 55 items and had good internal consistency (Cronbach alpha>0.72). Findings show that Filipino physical therapists are extremely aware and find the general elements of EPT understandable. However, the subjects rarely utilized the environment and other-than-humans in practice, but were partially involved in sustainable practices. The top perceived barriers were the lack of availability and access to resources and to the physical environment, and the lack of knowledge and awareness on EPT practices. The top perceived facilitators were acceptance of adjustments to change and the positive emotional response of clinical staff and patients. The SGD provided an explanation on how the perceived barriers and facilitators affected clinical EPT practice.

Discussion: The study revealed that Filipino PTs demonstrate the prerequisite characteristics inclined towards the implementation of EPT in the Philippines which can facilitate a smoother transition and integration of EPT into clinical practice. Filipino physical therapists have the opportunity to be at the forefront of promoting environmental sustainability in the healthcare system.
