CORRELATION OF CALF CIRCUMFERENCE WITH INSULIN RESISTANCE AND NAFLD
Authors: Maria Xavier Asha , Shenoy Damodar
Published: December 2024

Non-Alcohol Fatty Liver Disease is strongly linked to insulin resistance. Calf circumference is a substitute for lower body
adiposity and an inexpensive credible screening measure for the identification of subjects with aberrant adipose
distribution. Recent studies have shown that lower body subcutaneous fat also plays a pivotal role in accumulation of free fatty acids indicating it is
a risk factor in the pathogenesis of various metabolic disorders. Several studies have established that calf circumference may be a risk factor for
metabolic disorders independent of waist hip ratio and Body mass index. One of the goals in this study is to look into the fact whether an
infrequently used anthropometric parameter like calf circumference which represents both lean mass and peripheral fat has any correlation with
Non-Alcohol Fatty Liver Disease.

Published: December 2024

Magnetic Resonance Cholangiopancreatography (MRCP) is an advanced, non-invasive imaging modality that plays a
crucial role in the diagnostic evaluation of pancreaticobiliary diseases. This technique leverages magnetic resonance
imaging (MRI) to visualise the biliary and pancreatic ducts, providing high-contrast images essential for accurate diagnosis and treatment
planning. A hospital-based observational study was conducted in a tertiary care centre with a 1.5T Methodology: MRI, a sample size of 60 cases
referred for magnetic resonance cholangiopancreatography and normal anatomical variants of pancreaticobiliary junction were accessed and
categorised either as B-P type, P-B type or V/separate opening. Results: 28.3% of participants exhibited the pancreatic type junction in the bile
duct, while 40.0% showed the pancreatic duct-bile duct junction variant. Additionally, 31.7% presented the V-type junction. The Conclusion:
findings of our study have significant implications for the field of pancreaticobiliary research and clinical practice. By documenting the
prevalence and types of pancreaticobiliary junction variants, our study supports the development of tailored surgical and diagnostic approaches
that consider regional and demographic differences. This tailored approach can lead to safer surgical procedures, more accurate diagnoses, and
better overall patient outcomes. Our study not only corroborates existing findings but also enhances the understanding of pancreaticobiliary
junction variants, paving the way for improved clinical practices and patient care in diverse populations. The detailed insights from our study
contribute to the ongoing efforts to optimize diagnostic and surgical techniques, ultimately aiming to enhance patient safety and outcomes in the

Authors: Sandhya Sandhya , N Patil Rashmi
Published: December 2024

OBJECTIVES: To compare the effect of the reverse Trendelenburg position versus ramp on SNHAP, defined as the
interval between the induction of anesthesia and the occurrence of oxygen saturation (SpO2) of 92% in obese patients.
MATERIALS AND METHODS: In a randomised control study, 44 patients with minimal BMI 30 kg/m2 undergoing elective surgery under
general anaesthesia were randomly allocated to either group 1 (RP- ramp position ) and group 2 (RT- reverse Trendelenburg position) and the
effects on SNHAP in two groups were compared. RESULTS: The RT group showed significantly longer SNHAP (251.3vs222.2 seconds,
p<0.05) and faster return to 97% oxygen saturation after ventilation resumption (65.2vs73.4seconds, p<0.05) when compared with RP group.
CONCLUSION: In obese population, preoxygenation in reverse Trendelenburg position allows increased time for endotracheal intubation and
decrease risk of hypoxemia by increasing SNHAP, decreasing the time to obtain optimal preoxygenation and a faster return to safe saturation
levels.

Analysis of Financial Sustainability Indicators and their Reflection on the "Economic Cycle" in Iraq for the Period (2004-2022)
Authors: Abd Muhannad Khamis , Attia Ahmed Abd Saleh
Published: December 2024

The study investigates the impact of "financial sustainability" indicators on Iraq's "economic cycle" from 2004 to 2022. It hypothesizes that changes in these indicators affect the "economic cycle" both positively and negatively, with varying degrees in the short and long term, depending on the country's economic policies. Using the ARDL model for analysis, the results reveal a significant positive relationship between GDP and indicators such as the "public revenues"-to-expenditures ratio (X1), the "public debt"-to-GDP ratio (X2), and the tax gap index (X3). Conversely, a significant negative relationship was found with the "public revenues"-to-GDP ratio (X4), the oil revenues-to-"public revenues" ratio (X5), and the external debt-to-exports ratio (X6). The study recommends that fiscal policies be designed to counteract "economic cycle"s, encouraging austerity and investment during booms and expansionary measures during recessions to stabilize the economy and promote "financial sustainability".

Türkiye’de Kamu Sosyal Harcamalarının Gelir Dağılımına Bölgesel Etkileri: 2006-2021 Dönemi GİR Modeli Analizi
Authors: Keskin Abdulkadir
Published: December 2024

Sosyal harcamalar toplumsal sorunların çözümünde ve refahın artırılmasında sosyal politikanın ve dolayısıyla sosyal devletin önemli bir aracıdır. Sosyal harcamalar farklı amaçlar için kullanılmakla birlikte gelir dağılımındaki adaletsizliğin düzeltilmesinde de önemli bir role sahiptir. Türkiye’de 2001 sonrasında geçmiş dönemlere göre daha istikrarlı ekonomik ve siyasi bir dönemin yaşanmaya başlaması ile sosyal politika gelişme imkânı bulmuş ve buna bağlı olarak kamu sosyal harcamalarında önemli artışlar gerçekleşmiştir. Bu bağlamda yapılan çalışmanın amacı Türkiye’deki kamu sosyal harcamalarının gelir dağılımına etkisinin 2006-2021 dönemi için bölgesel olarak incelenmesidir. Bu amacı gerçekleştirmek için sosyal harcama alt bileşenleri olan kamu sosyal güvenlik ve sosyal yardım, eğitim ve sağlık harcamaları ile gelir da-ğılımı (Gini katsayısı) arasındaki ilişki bölgesel olarak Görünürde İlişkisiz Regresyon (GİR) modeli ile test edilmiştir. Elde edilen bulgulara göre kamu sosyal harcamaları ile gelir dağılımı ilişkisi bölgelere ve sosyal harcama alt bileşenlerine göre farklılıklar göstermektedir. Fakat genelleme yapılarak bulgulara bakıldığı zaman, sosyal harca-maların bölgesel gelir dağılımı üzerindeki etkisinin sınırlı olduğunu ve bazı bölgelerde etkisinin bulunmadığını söylemek mümkündür.
Culpa, responsabilidade e mudanças climáticas
Authors: Pereira Castanheira Nuno , Padilha Rafael
Published: December 2024

The purpose of this paper is to discuss the difference between guilt and responsibility, in the context of the ecological crisis, particularly after de floodings in Rio Grande do Sul (Brazil) and the following public shock. We begin by presenting a short historical and conceptual background, which will present a few important moments in the progressive occupation, by the ecological issues, of a central place in contemporary politics and society. In this moment of the argument, we will present Vandana Shiva’s criticism to the Modern development model, implemented throughout the world. We then turn our attention to the notion of ideology as discussed by Hannah Arendt, particularly regarding its purpose of total domination, legitimized by resorting to putative superhuman processes. In a third moment, we discuss what we called – tentatively – “generic form of the modern political subjectivity”, intending to show that it is dependent, along with the community it establishes, on the reproduction of existential crises for its preservation. Lastly, we discuss the distinction between guilt and responsibility, based on Hannah Arendt’s writings, closing the paper with brief remarks regarding an alternative form of political subjectivity, more capable of dealing with the ecological issues of our time.
A Marcha das Margaridas e A Condição Humana
Authors: Gruppelli Kurz Stefanie , Schio Sônia Maria
Published: December 2024

The text establishes an exchange between the ecofeminist agendas of the Marcha das Margaridas and the political thought of Hannah Arendt (1906-1975). To do this, it will compare the claims found in the document "Power and Political Participation of Women", elaborated by the Marcha das Margaridas in 2023, with the concepts of plurality and equality developed by Arendt in her work The Human Condition (1958). The aim is to demonstrate that, although Arendt is not (explicitly) an author of feminism, not even of ecology or ecopolitics, her work addresses these themes, which share common agendas with those movements, potentially providing significant theoretical support, especially for ecofeminism.
Resenha do Livro "Desobedecer" de Frédéric Gros
Authors: Castanho Germano , Dal Castel Mauricio
Published: December 2024

This paper aims to critically review the book “Desobedecer”, by the French philosopher Frédéric Gros, from a politico-philosophical perspective, highlighting the relationship between obedience and disobedience in general, and consent and civil disobedience in particular. In order to provide an original contribution, emphasis is placed on Chapter VIII, titled "Do Consentimento à Desobediência Civil”, analyzing, through the antithetical concepts that define it, the emergence of civil disobedience as a critical response to injustices legitimized by the social contract, understood as political consent. The paper concludes by arguing that civil disobedience, which is essential to Gros's notion of democracy, should be seen as a fundamental practice for the reactivation of the social contract, redefined as "making society," a collective disobedience, a refusal to "be governed in this way."

КИБЕРЭКСТРЕМИЗМ КАК СОВРЕМЕННАЯ
УГРОЗА НАЦИОНАЛЬНОЙ БЕЗОПАСНОСТИ
Authors: Ганаева Е.Э.
Published: December 2024

В статье проведен анализ вопросов относительно проблем киберэкстремизма и его влияния на национальную безопасность. Автором проведен анализ основных форм проявления киберэкстремизма и его последствий; роли социальных сетей в распространении и поддержке киберэкстремистских идей, намечены пути профилактики, определены меры противодействия киберэкстремизму в сфере национальной безопасности, определены круг угроз и перспективы развития киберэкстремизма и его возможные последствия для национальной безопасности государства. Автор пришел к выводу о том, что борьба с этими угрозами требует комплексного подхода, включающего совершенствование правовой системы, повышение цифровой грамотности населения, развитие технических средств выявления и пресечения экстремистской деятельности в Интернете, а также международное сотрудничество в области обмена информацией и опытом. Постоянная бдительность и адаптация к новым технологиям и методам киберэкстремизма будут играть ключевую роль в обеспечении национальной безопасности в будущем. Выводы, сделанные автором, можно выразить в следующем: в борьбе с киберэкстремизмом особое внимание следует уделять предотвращению распространения экстремистского контента в социальных сетях и на других интернет-платформах; компании социальных сетей должны нести ответственность за своевременное удаление такого контента и блокировку аккаунтов, распространяющих экстремистский контент; правительства и международные организации также могут помочь в разработке наиболее эффективных механизмов контроля и модерации контента, не нарушающих права человека, а сама борьба с киберэкстремизмом требует совместных усилий государств, международного сообщества, частного сектора и гражданского общества. Только сотрудничество всех заинтересованных сторон и комплексный подход к проблеме могут стать ключом к эффективной борьбе с киберэкстремизмом и предотвращению его пагубного влияния на общество.

Authors: Salimibani Milad , Dahaghin Ali , Boszczyk Agnieszka , Grasa Jorge , Siedlecki Damian
Published: December 2024

Purpose

The porcine eye serves as a valuable surrogate for studying human ocular anatomy and physiology because of its close resemblance. This study focuses on the influence of material properties, specifically Young’s modulus and Poisson’s ratio, on the crystalline lens overshooting amplitude during rapid eye rotation.

Methods

The Finite Element Method (FEM) is employed to explore various material property scenarios, and sensitivity analysis is conducted to assess their impact on the mechanical displacement of the crystalline lens apex. The measurements were made of three output parameters: maximum displacement, time of maximum displacement appearance , and stabilization time.

Results

The results highlight the significance of fine-tuning of the zonule’s material properties, particularly Young’s modulus, in achieving a reliable model. They suggest that fine-tuning of these parameters can lead to a highly reliable model, enabling in-depth research in the opto-dynamic simulations.

Conclusions

Having a complete examination of crystalline lens displacement in ex vivo porcine eye models and detailing crucial factors for accurate modeling will open the path for future studies especially in conditions affected by dynamic aspects of the crystalline lens or in in vivo research.
Finite Element Analysis of Double Diamond Lattice Structured Lumbar Interbody Fusion Cage with Different Biomaterials
Authors: Athikesavan D.  , Masilamany Santha Alphin  , Meganathan S.
Published: December 2024

Purpose

In recent years, low back pain has emerged as a significant global health issue, largely attributed to the prevalence of lumbar disc degeneration (LDD). This increases high demand on implant manufacturing due to the uniqueness of each patient’s anthropometry. Which creates a surge in the implant design and its performance study. This work employed finite element analysis to evaluate the efficacy of Interbody cage fusion in combination with different biostructures and biomaterials.

Methods

The Lumbar Model was created by incorporating a surgical implant cage that featured three different lattice architectures using Boolean operations. We constructed four models, one model that was not altered and three models that underwent surgical procedures. The surgical models consist of three types of lattice implants are Double Diamond (DD), Double Diamond Centre Support (DDCS), Double Diamond Side Support (DDSS).

Results

The results indicate that the Double Diamond (DD) lattice-structured polyether ether ketone (PEEK) material implant experiences the most deformation, measuring 0.67 mm, when subjected to axial rotation motion. An analysis indicates the implant made with the DDCS lattice structure and Ti-6Al-4V material is subjected to the least stress – it stood at 75.47 MPa as the smallest stress level recorded.

Conclusions

The result of endplate von mises stress shows the PEEK material with DDCS lattice structured implant have low stress. Ti-6Al-4V and Stainless steel having high stress of 20 MPa on endplates. Comparatively Ti-6Al-4V having very good response with literature data. These results are providing insights towards the selection of implant in future medical treatment.
Characterization of far-side occupant chest injuries in oblique side impact considering uncertainty
Authors: Lidong Zhang  , Sen Xiao  , Yu Liu  , Tiqiang Fan  , Jiapeng Li
Published: December 2024

Purpose

Oblique side impact is a common form of impact in life, and the far-side occupant’s chest is highly susceptible to injury in the impact process. This study analyzed the effects of different factors on the chest response of far-side occupants in oblique side impacts.

Methods

In this study, a simplified sled model was developed. After that, five factors, namely, impact velocity, impact angle, seat friction coefficient, seatbelt friction coefficient, and seatbelt force-limiting were considered as uncertain variables and randomly sampled. Sixteen sets of impact simulations with different parameters were performed using the sampled results to evaluate the farside occupant chest response.

Results

Results showed that the impact velocity was positively correlated with the chest deflection and chest acceleration, with correlation coefficients 0.77 and 0.92, respectively, and the impact angle was negatively correlated with the chest deflection and chest acceleration, with correlation coefficients -0.83 and -0.54, respectively. The seatbelt friction coefficient and force limiting value were positively and negatively correlated with the occupant’s chest response, respectively.

Conclusions

The results suggested that multiple variables collectively influenced occupant injury, and random combinations of different variables may play a critical role in impact outcomes. This study provides a reference for the study of occupant injury in far-side impacts.

Purpose

Biomechanical analyses of the swimming start performed by the best swimmers indicates the occurrence of a few effective start types. This issue has only been described to a small degree among adolescent swimmers. The objective is to determine kinematic differences in various parts of the swimming start to the front crawl among adolescent swimmers performing a start with flat (FT) or deep underwater trajectory (DT).

Methods

The study comprised 32 male swimmers aged 16-19 (average World Aquatics score=556±88 points). The trials were recorded using two cameras (above- and underwater). A kinematic analysis of the time from start to attain 5m was performed.

Results

The maximum submersion depth was 0.94±0.09 m (FT) and 1.21±0.11m (DT). Between-group differences were observed for FT and DT, respectively, in: attack angle at the submersion (38.37±6.85° and 44.90±6.08°), the distance of maximum submersion depth (5.24±0.36m and 5.58±0.50m) and underwater angles of attack during submersion (angle of the shoulders at the of submersion: 29.40±3.90° and 34.30±4.14°, angle of the hips at the submersion: 21.70±4.52° and 26.49±5.05°).

Conclusions

It was found that swimmers can successfully use different start variants. The underwater trajectory is primarily influenced by the body position at the moment the fingers contact with the water and during submersion, and not only by the manner of performing the push-off. The authors conclude that the characteristics of the start should not be based on one variable or its selected start phase - the description of the technique should comprise a set of kinematic indices from its different parts.
Aerodynamic Characteristics and Trajectory Analysis of Badminton Shuttlecocks
Authors: Lin Zhou
Published: December 2024

Purpose

This study aimed to investigate the aerodynamic characteristics and trajectory behavior of badminton shuttlecocks, focusing on the effects of design factors such as porosity, flexibility, and feather geometry on flight performance. The main research question was how shuttlecock design influences aerodynamic forces and resulting trajectories.

Methods

Wind tunnel tests were conducted on two feather and two synthetic shuttlecocks to measure drag, lift, and pitching forces across speeds of 10-50 m/s and angles of 0°-20°. Empirical correlations for drag and lift coefficients were derived via regression analysis. The effects of gaps and rotation were evaluated by modifying shuttlecocks. Trajectories were simulated by numerically integrating the equations of motion using the empirical force correlations and validated against high-speed video of players hitting shuttlecocks.

Results

Premium shuttlecocks displayed lower drag and higher lift than budget models. Feather shuttlecocks maintained higher rotation rates at high speeds compared to synthetic ones. Sealing gaps reduced drag by up to 10% for 75% sealed gaps. Stiffening synthetic skirts improved performance closer to feather shuttlecocks. Simulations matched experimental trajectories within 5% deviation for key metrics across different shots and shuttlecock types.

Conclusions

Shuttlecock design significantly impacts aerodynamic forces and flight trajectories. Factors such as porosity, skirt flexibility, and feather shape play crucial roles in performance. The developed simulation methodology can aid players in optimizing shots and manufacturers in designing better shuttlecocks. This research enhances understanding of shuttlecock aerodynamics and provides a foundation for future equipment innovations in badminton.

Purpose

The widespread use of heavy backpacks among adolescents raises concerns about the impact on musculoskeletal health. This study aims to investigate the effects of different backpack loads on shoulder strap tension during walking and running, using a spring-loaded shock-absorbing backpack.

Methods

Fifteen healthy male adolescents participated in the study. Each carried a backpack with loads of 3.5 kg, 7 kg, and 10.5 kg while walking at 2 m/s and running at 4 m/s. Shoulder strap tension was measured using custom-made tension sensors, and kinematic data were collected with a 3D motion capture system. Statistical Parametric Mapping (SPM) was applied to analyze tension variations across different gait phases.

Results

Shoulder strap tension increased significantly with heavier loads during both walking and running (p < 0.001). The tension varied throughout the gait cycle, with distinct patterns observed between walking and running. During walking, tension peaked at mid-stance, while in running, tension decreased during the absorption phase and increased sharply during propulsion. Significant differences between 7 kg and 10.5 kg loads were noted at specific gait intervals (p < 0.05).

Conclusions

Backpack load significantly influences shoulder strap tension, with variations closely linked to gait phases. These findings highlight the importance of ergonomic backpack design, particularly for reducing shoulder strain in adolescents.
