Why cheetah are endangered?
Authors: Frey Erzsebet
Published: November 2024

Historically, the cheetah (Acinonyx jubatus) was widely distributed throughout Africa and Asia. And could be found in past in 38 nations of Africa. A survey found that there were about 7,000 to 23,000 cheetahs living in Africa in the early 1970s. During the last decades, its distribution has shrunk dramatically and is currently confined to only 9% of its previous range, with an estimated 7,100 adult and juvenile individuals.
Predators of a cheetah
Authors: Frey Erzsebet
Published: November 2024

The lions and hyenas have been reported to greatly influence the distribution of cheetahs. However, the cheetah’s worst enemies are the degradation of suitable habitat, an insufficient supply of prey, and the species’ low genetic diversity. Groups of Cheetahs are less likely to be harassed by most predators than are single animals. Cheetah mothers are unable to defend small cubs against Lions that are four times their weight.

Published: November 2024

The main aim of this paper is to present a method for the conceptual design of a flying wing unmanned aerial vehicle using open-source software for rapid airfoil comparison and design and parametric geometry design and analysis. After adopting the final geometry the aerodynamic characteristics have been estimated including control derivatives. The obtained results have been compared to the results for similar flying wing projects to confirm that the presented method can give satisfying results. As the calculated results indicated that UAVs possess adequate flying qualities the prototype UAV was assembled using simple construction methods consisting of a hot wire cut styrofoam structure reinforced with plywood sticks, powered by a single pusher-propelled electrical BLDC motor. Calculated flight polar was then compared with data obtained from flight tests, verifying estimated stability and control characteristics of UAV design. The flight test results show that UAVs are controllable without a stability augmentation system, validating the use of methods described in this paper.
Study on kinetics and dynamics of the scraping-pressing mechanism of the compactor garbage truck
Authors: Quang Pham , Viet Vu , Quang Tran , Huu Nguyen , Duc Hong
Published: November 2024

This study comprehensively analyzed the kinematics and dynamics of the scraping-pressing mechanism of a garbage truck by using numerical methods. A multibody integrated with a hydraulic simulation model was established to investigate the mechanism's operation according to actual working conditions in a completed cycle with 18 seconds. The model was verified with the calculation at steady times, which showed high consistency. The results reveal that the mechanism operates in steady states almost all the time, with cylinder velocities ranging from 0.08 to 0.15 m/s. The cylinder velocity and acceleration fluctuate strongly when the mechanism accelerates or decelerates; however, the inertia effect is insignificant. The forces applied on joints are maximum at the end of the pressing process. Remarkably, the force applied on the joint connecting the scraping and sliding plate is highest, three times higher than the joint between the sliding plate and pressing cylinder and one and a half times higher than that between the scraping plate and scraping cylinder. The study's results can be applied to the design process of garbage trucks in special and specialized vehicles in general or used as a reference for enhancing the performance and optimizing the mechanism's mass, force, and materials.
Optimization of friction and electrical resistance performance in graphite-copper electrical contacts using Taguchi-based grey relational analysis
Authors: Bekhouche Djamel , Bouchoucha Ali , Zaidi Hamid
Published: November 2024

This study aims to investigate how the load, the intensity, and the polarity of electric current influence the frictional behavior and electrical resistance between a graphite pin loaded against a rotating copper disc. A pin-on-cylinder tribometer was utilized to achieve this. A gray relational grade obtained from gray relational analysis was employed to assess the performance characteristic in the Taguchi mixed L18 (2 1 x 3 2) method. The Taguchi design method determined the optimal control factors that affect the friction coefficient and electrical resistance. Analysis of variance (ANOVA) was employed to analyze the effects of the control parameters on the friction coefficient and electrical resistance of the contact. The experiment parameters included applied normal load (3, 5.5, and 8.5 N), electrical current (10, 25, and 30 A), and polarity (cathode and anode). The analysis results indicated that the polarity was the primary factor influencing the friction coefficient, while the electrical current was the most effective factor in the electrical resistance of the contact. The optimal control parameters for achieving the lowest friction coefficient values were X1Y3Z1, while for the lowest electrical resistance values were X2Y3Z3. Based on the gray relational analysis results, the optimal parameters for minimizing both the friction coefficient and electrical resistance were X1Y3Z1.
Design and develop a robot arm to automatically feed workpieces for laser engraving machines
Authors: Xuan Trung , Anh Duy
Published: November 2024

This study presents the design, development, and experimental evaluation of a 4-DOF SCARA robotic arm, integrated with a programmable logic controller (PLC) and stepper motors, for automating workpiece handling in laser engraving processes. The system enhances both safety and efficiency by autonomously managing the grasping, placement, and retrieval of workpieces, thereby reducing human exposure to laser hazards. The robotic arm, equipped with dual vacuum suction heads, enables precise "pick and place" operations by loading new workpieces and removing finished products simultaneously. This dual-action design minimizes cycle time by allowing continuous handling throughout the engraving process. Powered by stepper motors controlled via a PLC, the robotic arm achieves high precision in motion, allowing for accurate alignment of each workpiece. Experimental results demonstrate the system's capability to maintain consistent product quality and uniformity, even with the complex demands of grasping and aligning workpieces. This automated solution represents an efficient and reliable alternative to manual operations, addressing industry needs for precision, safety, and productivity in repetitive laser-based manufacturing environments.
Gendered Taxation: IMF Tax Advice and the Unintended Disempowerment of Women
Authors: Donno D. , Kern A. , Reinsberg B.
Published: November 2024

Case research points to the gendered effects of the value added tax (VAT), which may particularly disadvantage women by crowding out their economic participation. A key driver of VAT introductions has been the International Monetary Fund (IMF). To counterbalance of-payments woes, IMF advice for cash-stripped countries has frequently focused on shifting toward broad-based consumption taxes while lowering trade taxes and corporate income taxes. We expect this tax policy advice – while ostensibly gender-blind – to contribute in practice to a deterioration in women’s socioeconomic well-being. To test this hypothesis, we construct a panel dataset for 147 countries from 1980 to 2016 and estimate the effect of IMF programs on women’s economic participation, education and health. Accounting for selection effects, we find that women’s life chances deteriorate relative to men’s if a country undergoes an IMF program with tax conditionality. We corroborate these findings to demonstrate the mechanism underlying these effects by showing a negative effect of IMF-induced de jure VAT adoption on women’s life chances. We provide complementary individual-level evidence from the World Values Surveys based on 98 countries from 1981 to 2019. We show that during an IMF program with tax conditionality, women are significantly less satisfied with home life and report more material hardships. Our results provide evidence of the potential for unintended consequences of IMF revenue prescriptions for women, supporting calls for increased attention to gender-responsive budgeting.

Authors: Suhatmi Erna Chotidjah , Dasman Sunita , Badarisman Dudih , Nahar Aida , Jaya Anak Agung Ngurah Adhi
Published: November 2024

This study examines the impact of sustainability reporting on corporate financial performance through a comprehensive global analysis. With increased stakeholder interest in environmental, social, and governance (ESG) factors, corporations worldwide have adopted sustainability reporting as a tool to showcase their commitment to sustainable practices. The research investigates whether these reporting practices contribute positively to financial outcomes, analyzing data from a diverse sample of industries and regions. Using both quantitative and qualitative metrics, the study evaluates the correlation between the depth of sustainability disclosures and key financial indicators, such as return on assets (ROA), return on equity (ROE), and stock performance. Findings reveal that companies with robust sustainability reporting tend to experience enhanced financial performance, attributed to factors like improved brand reputation, operational efficiency, and stakeholder trust. However, results vary across industries and regions, indicating that local regulatory frameworks and cultural contexts significantly influence the degree of financial benefit derived from sustainability initiatives. This study underscores the strategic importance of sustainability reporting and suggests that, while not universally beneficial, it can serve as a catalyst for financial success in corporations committed to sustainable development. These findings contribute to the growing body of literature on corporate sustainability and provide valuable insights for policymakers, investors, and managers aiming to understand the financial implications of sustainability practices globally.

Published: November 2024

Nowadays Fused Deposition Modeling, a widely utilized additive manufacturing technology, is significantly transforming as modern production processes. Beyond basic uses to it role in sustainability, Fused Deposition Modeling offers processing potential for implanting circular economy by reducing virgin materials consumption and enhance the integration of waste food for sustainable 3D printing. This research paper investigated the production of new composite materials based on spent coffee grounds. In addition, PLA and SCG at various contents (0, 3, 5, 10, and 15 wt%) were dried and premixed, then processed into PLA/SCG composite pellets using twin-screw extrusion. These pellets were successfully converted into filaments and subsequently used for 3D printing. The effect of spent coffee grounds in PLA composites was investigated via physical and mechanical analysis of 3D printed samples. Regarding density measurements, results revealed that adding up to 5 wt% of spent coffee grounds increased the density while further additions led to a decrease which due to the printing parameters such as extrusion temperature and nozzle diameter. Considering the mechanical properties, the Young’s modulus increased once the spent coffee grounds content reached 3 wt% and then decreased. In the other hand, there was no enhancement in tensile strength and elongation at break which corroborating with density measurements. This mainly contributed to the changes in mechanical properties caused by printing parameters. This study demonstrates that coffee waste can be used as a filler in environmentally friendly composites for 3D printing, with a maximum SCG content of 15 wt%. This approach not only promotes the reuse of coffee waste but also reduces the cost of traditional PLA filaments.

Authors: Bhanot Deepak , Hashmi Sadaf , Suneetha K , Parmar Devendra
Published: November 2024

The evaluation of credit risk (CR) has become prominent in recent years, particularly among
banks, as default rates are on the rise and economic insecurity remains persistent. Traditional credit
scoring techniques oftentimes are inadequate and provide little means for risk estimation,
necessitating the development of new models using data science methodologies. In this study, a
novel Intelligent Dwarf Mongoose tuned Light Gradient Boosting Machine (IDM-LGBM) model
that boosts the accuracy of CR and improves forecasting performance, is introduced. The Light
Gradient Boosting Machine model's hyperparameters were optimized using the Intelligent Dwarf
Mongoose technique, improving the model's predictive strength. The CR dataset was gathered
from the Kaggle platform. The data is then pre-processed using Z-score normalization. To evaluate
the efficiency of the suggested IDM-LGBM technique, which has been implemented employing a
Python platform. Results show that the IDM-LGBM model performed significantly better than
conventional methods in terms of recall (98.1%), accuracy (97.2%), F1-score (97.4%), and
precision (96.5%). Subsequent studies could concentrate on addressing real-time data streams and
enhancing models to respond to the changing credit environment.

SUMMARY The purpose of our study was to describe the epidemiological, diagnostic, therapeutic and evolutionary aspects of the surgical management of abdominal emergencies in public health facilities in the Ziguinchor region. Materials and Methods: This was a retrospective and descriptive study, lasting 24 months, from 01 January 2018 to 31 December 2019 (24 months). It was carried out in the EPS surgical departments of the Ziguinchor region: Ziguinchor Regional Hospital, Peace Hospital and the Joint Medical Centre of Ziguinchor. All records for patients over the age of 15 years, who are in emergency management for abdominal surgical conditions, who have had immediate or delayed surgery were included. The parameters studied were the epidemiological, diagnostic, therapeutic and evolutionary data of the patients. The Microsoft Office Excel 2016 software was used for data entry and analysis by the EpiInfo 7.2 software. Results: Our study included 286 patient files. They accounted for 31.5% of UAA consultations in the Ziguinchor region. The average age was 38.51 years with extremes of 15 and 88 years. The sex ratio was 3.6. The main reason for consultation was abdominal pain (100%). The interval [0H-12H[ following the beginning of their symptomatology, was the most frequent consultation time (37.41%). Most of our patients (78.32%) had no medical history. The history of abdominal surgery was found in 10.5% of patients. Ultrasound was the most prescribed exam (54.2%), followed by CT-scan (13.99%) and abdominal X-ray (13.3%). Our patients (83%) were operated on within 12 hours of admission. Locoregional anesthesia, exclusively by rachianaesthesia, was performed at a rate of 59.9%. Acute appendicitis dominated our study (42.65%), followed by generalized acute peritonitis (24.82%) and strangulated hernia of the abdominal wall (16.42%). Abdominal trauma was found in 17 patients (5.94%). Abdominal contusions accounted for 64.70% of abdominal injuries compared to 35.3% for wounds. Appendectomy was the most performed surgical procedure with nearly 161 procedures (56.29%). Intraoperative incidents were 6.64%. Of these, 53.84% were surgical and 46.16% were anesthetic. Morbidity was 7.34%, dominated by parietal suppurations. Mortality was 3.15%. The average length of hospitalization was 8.76 days. Conclusion: Abdominal surgical emergencies are a real public health problem in terms of morbidity and mortality. The management is multidisciplinary. Improving the management of these emergencies in the Ziguinchor region requires a reduction in consultation times and good perioperative management.

Identifying The Conceptualization, Measurement of Retirement Planning: A Systematic Review
Authors: Guo Jing , Nazri Mohammad , Fernandez Kevin
Published: November 2024

Retirement planning (hereafter, RP) has become a fundamental topic in academic research over the last decade. Despite its development, there is no consensus among scholars on its measurement. This study aimed to tackle the challenge of evaluating RP behaviors across different domains. A comprehensive review journal publications were retrieved the 2000–2023 period from Web of Science. The presentation of methods and results followed the recommendations outlined in the PRISMA guidelines. 32 journal publications were included in this review. Three key trends emerge from the results of our systematic review of the measurement of RP: a majority (53.13%) of RP studies utilizes a unidimensional approach; few measurements of RP were based on any theory; a lack of consistency in the measurement multidimensional approaches. Additionally, we have introduced a thorough framework has also been proposed to define RP in terms of dimensions, antecedents and outcomes. The authors suggest researchers investigating RP’s financial aspects consider Stawski et al.’s work for a nuanced measurement framework. For those interested in a comprehensive analysis of various facets of RP, the researchers propose Muratore et al.’s three-dimensional framework for a comprehensive approach to measurement.

Authors: Shahinnia Nina , Rahnejat Amir Mohsen
Published: November 2024

Objective: The objective of this study was to investigate the relationship between distress tolerance, Dark Triad personality traits, and marital conflict, with ego strength as a mediating variable, in women seeking divorce. Methods and Materials: The study utilized a descriptive-correlational design and included a sample of women seeking divorce who visited marital counseling clinics in District 3 of Tehran during the spring of 2024. Data were collected using self-report questionnaires: the Marital Conflict Questionnaire, the Short Dark Triad Personality Questionnaire (SD3), and the Psychological Ego Strength Inventory (PIES). Structural equation modeling (SEM) was employed for data analysis. Findings: The results revealed that distress tolerance had an indirect and significant effect on marital conflict through the mediation of ego strength (β = -0.366, p = 0.001). Among the Dark Triad traits, Machiavellianism showed an indirect and significant effect on marital conflict (β = 0.170, p = 0.001), while psychopathy and narcissism did not exhibit significant indirect effects. Narcissism had a direct positive effect on marital conflict (β = 0.275, p = 0.000), whereas psychopathy and Machiavellianism did not have direct effects. Ego strength had a significant negative effect on marital conflict (β = -0.595, p = 0.000). Conclusion: Machiavellianism indirectly influences marital conflict through the reduction of ego strength, while narcissism has a direct positive effect on conflict. Ego strength plays a key role in reducing marital conflict, suggesting that interventions aimed at enhancing ego strength and addressing manipulative personality traits may be effective in mitigating marital conflict among women.

As the smallest unit of life, a person has the ability to function independently of himself to maintain his survival. The smallest entity that has the ability to reproduce and divide is a cell. The two types of cell architecture are eukaryotic and prokaryotic. Plant cells will also be discussed apart from that. Plant cells will be closed separately even though they are eukaryotic and have special organelles. Every biological process is cellular and controlled. As a result, as long as all basic needs are met, the cell can operate independently. Organisms, or living things, consist of many cells (multicellular) or one cell (unicellular), such as bacteria, archaea, fungi, and protozoa. Viruses are microscopic organisms that exist outside cells. Viruses are obligate parasites because viruses do not have the cellular machinery needed for reproduction, so viruses can only reproduce in living things by entering and exploiting their cells.

Water quality plays an important role in maintaining the balance of aquatic ecosystems, including the abundance and diversity of plankton. This study aims to analyze the effect of various water quality parameters such as temperature, dissolved oxygen (DO), carbon dioxide (CO2) levels, Biochemical Oxygen Demand (BOD), pH, brightness, and turbidity on plankton diversity in Bozem. Data were obtained from eight observation stations with water quality parameter measurements and plankton sampling. The results showed that the water quality in Bozem was not optimal, with low DO values ​​(1.79 mg/L), high water temperatures (average 31.05°C), and low brightness (0.30 m), which contributed to the decline in plankton abundance. A total of 39 plankton genera were identified, with Synedra as the most dominant genus. Poor water quality inhibits plankton growth, which can impact the balance of the food chain in these waters. This study shows the importance of better water quality management to maintain the sustainability of aquatic ecosystems in Bozem. This study also contributes to the understanding of the multifactorial interactions between water quality parameters and plankton.
