STRESS, EQUIVALENT STRAIN AND DEFORMATION FOR MACHINING OPERATION UTILIZING EXPLICIT DYNAMIC ANALYSIS FOR VARIOUS MATERIALS
Authors: Valiavalappil Anand
Published: April 2024

Subtractive and additive manufacturing methods constitute the two main categories of modern manufacturing technology used in the manufacturing sector. The subtractive method is used for material removal and is performed in (Brass, Aluminum and Teflon), the machining process is achieved using CNC (Computer Numerical Method) turn machine.

The main objective of the paper is to perform FEA (Finite Element Analysis) over the three material (Brass, Aluminum and Teflon). The CNC machine is used to perform a machining over the three-material stated above, but within the CNC machine there is no provision for achieving the various values of (stress, strain and deformation) during the machining operation. During the machining process, it’s very difficult to get and accurate value of stress for the tool and raw (test) material, so Ansys FEA analysis method is adopted to predict the parameter like stress, strain and total deformation. The analysis part is achieved by the developing the CAD model using Solid work and FEA analysis using Ansys and thereby the output will be helpful to understand the various stress parameters.

The results highlight that Teflon has a higher value for total deformation followed by aluminum and brass. The equivalent strain for the Teflon is higher and followed by brass and aluminum. The stress is acting in axial and compressive direction, so brass have a higher value followed by aluminum and Teflon. This method and analysis procedure can be adopted for understanding the deformation, stress and stain acting on any material, which will be highly useful for material of higher with a higher hardness value.

Authors: Yıldız Silahlı Nicel , Güler Beyza Nur
Published: April 2024

INTRODUCTION: Vaccine hesitancy is a world-wide public health problem still persisting despite the mounting scientific evidence of the positive effects of vaccines on community health. The prevalence and causes vary based on cultural and sociological characteristics. In our study, we aimed to evaluate the situation of vaccine acceptance among parents who gave birth in our hospital.
METHODS: This study is a retrospective descriptive study. The medical and vaccination records of mothers and babies born between June 2017 and June 2022 at Istanbul Medipol University Education and Research Hospital were examined. Socio-demographic data, mother's age, prenatal, natal and postnatal history, baby's gender, birth weight, vaccines and vitamin K status were recorded on the data form. SPSS software was used for statistical analysis.
RESULTS: The total number of births in our hospital over a 5-year period was calculated as 15,417. The population of the study was made up of 192 (1.24%) cases, registered in epicrisis and infant birth records as vaccine refusal. The mean age of mothers was 30.72 (min: 20; max: 45) and the mean gestation week was 38.28 weeks (min: 32; max: 42; missing: 22). mean birth weight of the babies was 3008.78 grams and 56.25% of the babies were male. Considering vitamin K administration status of the cases, 61.73% (n: 121) did not accept.
DISCUSSION AND CONCLUSION: Vaccination is the most effective method of preventing infectious diseases. Vaccination, one of the basic elements of preventive medicine in child health monitoring, should be carried out uninterruptedly. As a result, vaccine hesitancy rates can be reduced by partnering with each healthcare worker in solution strategies to increase vaccine acceptance. Education and awareness studies are also needed in this regard.

Authors: Ekpo Edidiong-Obong , UDOFIA KUFRE , Obot Akaninyene
Published: April 2024

In this paper, a Long-Term Evolution-Advanced (LTE-A) Modified Best Channel Quality Indicator (M-BCQI) Scheduler is proposed for enhanced cell edge throughput performance. The scheduling algorithm utilizes two time slots, each of 0.5 ms in length, with the First Time Slot (FTS) implemented with the Best Channel Quality Indicator (BCQI) algorithm has a CQI-focused Resource Block (RB) allocation mechanism, while the Robin (RR) algorithm is the mechanism used in the Second Time Slot (STS) for RB allocation. Vienna LTE system level simulator was used for the proposed scheduling algorithm assessment. The results obtained showed significant improvement, indicating 44% superior cell edge performance and 56 % better fairness index in comparison to BCQI. However, M-BCQI slightly underperformed by 4.2% in terms of average throughput in comparison to BCQI and by 7% in comparison to RR in terms of fairness index.
Development of Selenium-Silica Nanocomposites By Sol-Gel Process Utilizing Three Different Reducing Agents and Its Characterization
Authors: Mukherjee Soumya
Published: April 2024

Nanocrystalline Selenium was synthesized within a silica matrix using a sol-gel method with high-purity SeO2, ethyl alcohol, distilled water, and TEOS (Tetraethyl orthosilicate). This process encapsulated the selenium dioxide in the silica matrix, which was then reduced at about 100°C using an oil bath. Three reducing agents were employed: acetone vapor, and sodium borohydride (NaBH4) and hydrazine (N2H4) in liquid form. DSC-TGA analyses of the precursor mixture determined the crystallization temperature for selenium nanoparticle formation within the matrix to be around 100°C. Post-heating phase analysis via XRD revealed hexagonal structures, with crystallite sizes between 33 and 43 nm determined using Debye-Scherrer's formula. Morphological studies showed irregular polygonal shapes with rough surfaces, with particulate sizes under 0.2µ for acetone vapor, around 0.1µ for hydrazine, and slightly over 0.1µ for sodium borohydride. Time variations were explored to observe phase and crystallite size changes. FTIR analysis was conducted for bonding assessment, revealing M-O coordination. The composite's absorbance was examined through UV-VIS spectroscopy, and its morphological attributes were investigated using FESEM analysis, complemented by EDX to determine elemental composition

Andreas Pannonius és az Énekek énekéhez írt kommentárja
Authors: Bíró Csilla
Published: April 2024

Andreas Pannonius, a 15. századi magyar származású karthauzi szerzetes az 1460-as évek folyamán írta Énekek éneke-kommentárját (Expositio super Cantica canticorum). A szöveg befejezésére valószínűleg a ferrarai San Cristoforo karthauzi rendházban került sor. A kommentár egyetlen fennmaradt, nem autográf, 1505-ből származó kéziratát az Országos Széchényi Könyvtár Kézirattára őrzi. A 110 fólió terjedelmű kézirat, amelyet a szerző a szeplőtelen fogantatás tanának védelmére alkotott, számos pontján kapcsolódik a misztikus teológiai irodalomhoz. Lényeges elemei például a cselekvő és a szemlélődő életforma összehasonlítása, a passiómisztika körébe tartozó, Krisztus szenvedéseit felidéző memoria passionis-részletek megjelenítése vagy a felemelkedési misztika ismert költői képe, a hegy metafora. Az Énekek éneke-kommentár bemutatása mellett arra is kitérek, hogy ez az európai viszonylatban is kiemelkedő minőségű munka miért maradhatott visszhang nélkül mind a saját, mind a későbbi korokban.

El Marco del Análisis Institucional y Desarrollo. Una Herramienta para el Conocimiento del Territorio
Authors: Fagiolo Mario
Published: April 2024

Este artículo invita a reflexionar acerca de la maduración compleja del concepto de “desarrollo” y de la exigencia de una nueva relación entre la humanidad, la sociedad y la naturaleza. Relaciona el “desarrollo económico local” al origen geográfico del concepto de “territorio” y lo enlaza con la necesidad de una “nueva unidad de análisis”, más allá de la empresa (economía neo clásica) o del sector (economía marxista), propone el espacio geográfico donde se genera “la vida”: el “oikos”. Este nuevo constructo se desarrolla en torno a los análisis de la Nueva Economía Institucional (NEI) que hace referencia a la organización social de la vida, cuya creatividad trasciende tanto al mercado como al estado. Las relaciones complejas – entre el grupo humano y el territorio – para ser estudiadas y aprehendidas necesitan de herramientas complejas, fluidas, dinámicas y flexibles. El “Framework IAD” es una herramienta ideada para facilitar el desarrollo de un método comparado para el análisis institucional. La finalidad de esta presentación es guiar los investigadores y los actores en el uso de una herramienta de análisis institucional del territorio.

A castração cirúrgica é o método contraceptivo mais eficiente e indicado na medicina veterinária, pois atua no controle de zoonoses e doenças infecciosas, além de contribuir para a docilidade, diminuição de perambulação e demarcação de território. Dessa forma, também atua como uma ferramenta de saúde pública para o controle de superpopulação animal. O objetivo deste trabalho foi avaliar quatro protocolos analgésicos na castração cirúrgica de gatas para determinação da melhor estratégia farmacológica no controle álgico, utilizando como ferramenta de aferição da dor a Escala da dor da Universidade de Melbourne. Selecionou-se 60 gatas hígidas, sem raça definida, com idade entre 6 meses e 2 anos provenientes da cidade de Bandeirantes, Paraná, Brasil. Os animais foram divididos em 4 grupos: Grupo 1 - 15 animais que receberam dipirona (25 mg/kg, s.i.d.); Grupo 2 – 15 animais que receberam cloridrato de tramadol (3 mg/kg, t.i.d.) associado à dipirona (25 mg/kg, s.i.d.); Grupo 3 – 15 animais que receberam meloxicam (0,1 mg/kg, s.i.d.) associado à dipirona (25 mg/kg, s.i.d.); e Grupo 4 – 15 animais que receberam meloxicam (0,1 mg/kg, s.i.d.). Os medicamentos foram administrados por via oral. Os animais foram observados e assim feitas as médias (scores) na escala de Melbourne nos tempos pós-cirúrgicos 4, 24, 48 e 72 horas. O fármaco meloxicam apresentou o melhor resultado no controle da dor e o menos eficaz foi o protocolo utilizado pela associação de tramadol com dipirona. Conclui-se que o meloxicam foi o protocolo mais indicado para a mitigação da dor em gatas submetidas à técnica de ovariohisterectomia eletiva.
A Case of Forming Test for the Diagnosis of PFO Combined Dynamic Left Ventricular Outflow Tract Stenosis after Occlusion
Authors: Liu Mengxuan
Published: April 2024

This patient was diagnosed with Patent Foramen Ovale (PFO) due to recurrent headaches, and her headaches improved significantly after oval foramen occlusion, but a grade 3/6 coarse murmur was heard in the aortic valve auscultation area, and left ventricular outflow tract stenosis was suggested by cardiac ultrasound. This change may be related to a variety of factors, suggesting that we should do a good preoperative assessment of the patient; intraoperative operation as gentle as possible to reduce the damage to the surrounding tissues; postoperative operation should be strengthened to avoid the progression of the inflammatory process, and at the same time to pay attention to the patient's symptoms, signs and dynamics of the relevant examinations to reduce the incidence of complications.
Advances in the Study of Thyroid Hormones and Atrial Fibrillation
Authors: Chen Zeni , Yang Deguang
Published: April 2024

Atrial fibrillation (AF) is a common cardiac arrhythmia characterized by irregular, rapid and ineffective contractions of the atrial rhythm. The relationship between thyroid hormones and AF has been of interest because past studies have identified that thyroid hormones play an important role in the cardiovascular system and that there is a strong link between abnormal thyroid function and AF. Hyperthyroidism is often accompanied by symptoms of arrhythmia such as increased heart rate and arrhythmia, whereas hypothyroidism patients may exhibit abnormalities such as slowed heart rate and enlarged atria. Thyroid hormones are involved in the onset and development of AF through several pathways. First, thyroid hormone may affect the electrophysiological properties of cardiomyocytes, altering the excitability and repolarization process of atrial cells. Second, thyroid hormones may also affect the structure and function of the atria, leading to atrial enlargement and fibrosis, thereby increasing susceptibility to AF. In addition, thyroid hormones may alter the maintenance and regression of AF by affecting the autonomic regulation of the cardiovascular system. This suggests that thyroid hormones play a key role in the pathophysiologic mechanisms of AF. In recent years, an increasing number of studies have focused on the relationship between thyroid hormones and AF and have attempted to reveal their specific mechanisms of action. Some studies have suggested that modulation of thyroid function may be a new strategy for the treatment of atrial fibrillation. In this article, we present a review of the latest research progress on thyroid hormones and atrial fibrillation.

Preparation and Evaluation of in situ Ophthalmic Gel with a Dual Triggered Mechanism for the Delivery of Gatifloxacin and Betamethasone
Authors: Ali Fatima Mustafa , Al-Shohani Athmar Dhahir
Published: April 2024

Background: Bacterial infections of the eye are treated by administering ophthalmic solutions containing corticosteroids and antibacterial agents. The main challenges faced when used for topical instillation are precorneal fast clearance and multiple applications, particularly with gatifloxacin. Objectives: To develop an ocular gel that utilizes both ion-induced and thermal-sensitive mechanisms to achieve gelation. Methods: We prepared and compared formulations containing different percentages of poloxamer 407 and gellan gum (F1–F24) in terms of gelation temperature, gelling capacity, gelation time, and permeation. We tested the optimum formulation for isotonicity and irritation in rabbits. Results: The formulations' pH varied from 6.7 to 7.3. Formulations that passed the gelation temperature test successfully were F6, F7, F9, and F10. For both drugs (F6, F7, F9, and F10), the drug content percentages ranged from 98.64% to 99.95%. In situ, gels (F6, F7, F9, and F10) showed pseudoplastic shear-thinning rheological behavior, which means that their viscosity decreased as the angular velocity went up. F7, which contains 17% poloxamer and 0.5% gellan gum, had 15 seconds of gelation time at 34oC and remained in gel form for 270 min. It was isotonic and did not change the size or shape of RBCs when topically applied. The rabbit's eyes did not experience irritation due to the extended release of both drugs. Conclusions: The new in situ gel formulation may be a superior alternative to the traditional eye drops of gatifloxacin and betamethasone for ocular infections.

Empirical Analysis of Factors Affecting Stock Liquidity --Taking Ping An Bank as an Example
Authors: Wang Kesu
Published: April 2024

With the continuous development of the Chinese economy, the stock market has become one of the important choices for investors, and the liquidity of the stock market has always been the focus of investors. Ping An Bank is one of China's well-known commercial banks and occupies an important position in the A-share market. The goal of this paper is to study the relationship between stock liquidity and return volatility, risk factors, circulation market value and cross-period of risk factors. Through ordinary least squares (OLS) regression analysis, it can be found that earnings volatility and circulating market value have an impact on stock liquidity significantly, that is, the higher the earnings volatility and circulating market value, the higher the stock liquidity. Risk factors and cross-terms of risk factors have no significant influence on stock liquidity. These findings have important implications for investors and market regulators to help them more fully assess stock value and risk and make more informed investment decisions.
Bitcoin Price Prediction Based on Multiple Machine Learning Algorithms
Authors: Hu Yaowen
Published: April 2024

In this paper, we performed bitcoin price prediction based on bitcoin price dataset using Support Vector Machine model, Random Forest model, Neural Network model, XGBoost model and LightGBM model and evaluated the performance of these models. We divided the Bitcoin price dataset into training and test sets in a ratio of 7:3, where 70 were used as the training set and 30 as the test set. The models were trained with the training set and tested with the test set using the stock price change (yield) as the target variable and other variables as input variables. By comparing the MSE, RMSE, MAE, MAPE and R of the different models were evaluated and it was found that XGBoost has the best performance and the best prediction. The performance of the other four models ranged from good to poor, including LightGBM, Random Forest, Support Vector Machine and Neural Network. Among them, the neural network, whose MSE is tens of times higher than the other four models, performs the worst. The research results in this paper can provide reference value for future Bitcoin price prediction, and also provide some reference for choosing appropriate machine learning models.
Research on the Optimal Pricing for Life Insurance
Authors: Huang Yuxi
Published: April 2024

Term life insurance is a policy that guarantees the buyer of the policy insurance benefit upon their death for a period of time in exchange for a premium paid by the insurance buyer to the seller yearly for a set number of years. Purchasing life insurance has become an important, if not necessary, financial investment in everyones life, as it protects their family from a potentially devastating financial loss if they unexpectedly pass away. This paper combined multiple variables in order to compute a pricing formula for life insurance. The final result is that as the age of purchase increases, the premium, or, in other words, the price of the life insurance using my pricing formula, increases exponentially, while the profit received decreases exponentially.

Correlation Analysis Between National Fertility Rate and Socioeconomic Development: A Study Based on Birth Rates in China
Authors: Meng Zhihang
Published: April 2024

China's declining fertility rate poses significant challenges to social and economic development. The deceleration in population growth, potentially leading to negative growth, has diverse implications. Socially, an aging population strains the social security system, escalating demands for healthcare and pensions, while insufficient supply may compromise social welfare. The labor market is also affected, as an aging populace may cause labor shortages and increased labor costs, impacting economic development. Economically, the fertility rate decline hampers economic growth by slowing down population and economic scale expansion. Adjustments to the labor market and industrial structure may induce short-term economic fluctuations and unemployment issues, negatively impacting the social economy. Addressing falling fertility rates requires government intervention. Strengthening the social security system is crucial to meet challenges posed by an aging population. Additionally, policies encouraging fertility are essential, involving support for healthcare, education, and childcare services. Human resource development must be emphasized to enhance workforce skills, adapting to labor market changes and economic needs. In conclusion, China's declining fertility rate profoundly influences social and economic development. Government measures are imperative to ensure sustainable and healthy socio-economic growth.

Rural Hollowing-Out Revisited: A Comparative Literature Review Between China and Japan
Authors: Yuan Weixuan
Published: April 2024

The issue of rural hollowing out is not unique to China, as various countries worldwide have witnessed different degrees of this phenomenon during the process of urbanization. Japan and China, among those nations grappling with rural hollowing out, share noteworthy similarities, rendering Japan's governance experience particularly instructive for China. This paper undertakes a comparative analysis of Japan's issues with rural over-saturation and China's challenges with rural hollowing, revealing disparities in the formation mechanisms and timelines of these phenomena in the two countries. Notably, China experienced the hollowing-out problem later than Japan, and the process unfolded at a swifter pace. Examining governance policies, Japan advocates for the autonomous development of hollow villages in later stages. China stands to benefit by adopting Japan's supportive policies for rural areas, such as the 'one village, one product' initiative, which encourages hollowed villages to explore their unique strengths and specialize in products for endogenous development. In the realm of coordinating urban-rural relations, China can draw inspiration from Japan's strategy of "supporting rural areas with cities." This entails fostering rural development by investing in education and healthcare infrastructure in central cities, thereby promoting urban-rural integration.

Comparison and analysis of prediction accuracy between traditional machine learning algorithms and XGBoost algorithm in music emotion classification
Authors: Yang Mengxi
Published: April 2024

Music emotion classification refers to determining the emotional types of music, such as happiness, sadness, anger, and passion, based on aspects like rhythm, melody, and tone. The development of artificial intelligence can be applied to music recommendation by employing machine learning algorithms to ascertain emotional attributes of music, enabling precise music suggestions for users to enhance their musical experience. This paper compares and analyzes the classification performance of traditional Random Forest machine learning algorithms and the XGBoost model on a Turkish music emotion dataset. We selected a comprehensive dataset from Kaggle, containing a vast array of music samples and their corresponding emotional labels, making it an extensive music emotion classification dataset. From the experimental results, it's evident that the traditional Random Forest machine learning model outperforms the XGBoost model in terms of accuracy, precision, and recall. The accuracy of the traditional Random Forest machine learning model stands at 80.8%, whereas the XGBoost model's accuracy is 75%. The recall rate for the traditional Random Forest machine learning model is 80.8%, while for XGBoost, it's 77.2%. The F1 score for the traditional Random Forest machine learning model is 80.5%, whereas for XGBoost, it's 75.3%. These parameters indicate that the traditional Random Forest machine learning model exhibits superior predictive performance in music emotion classification. However, the XGBoost model possesses its own advantages, such as faster learning and prediction speeds, high accuracy, and strong generalization capabilities. In summary, the traditional Random Forest machine learning model demonstrates better robustness and interpretability, effectively handling samples with noise and missing data, thus finding widespread practical application. On the other hand, the XGBoost model excels in rapid training and prediction, coupled with higher accuracy and versatility, making it advantageous in dealing with large datasets. The research outcomes of this paper hold significant importance for the study and application of music emotion classification. The experimental results presented herein offer valuable insights for researchers and practitioners, aiding them in selecting appropriate machine learning models, optimizing, and adjusting them to achieve the best classification results.
