The automotive industry is increasingly focused on reducing vehicle weight, leading to the widespread adoption of composite materials with high strength-to-weight ratios in both aviation and automotive sectors. These materials are gradually replacing traditional options like steel. Leaf springs, one of the oldest and most common suspension components, continue to be widely used in vehicles. This study aims to replace conventional multi-leaf steel springs with mono-composite leaf springs while preserving the same load-carrying capacity and stiffness. Composite materials, such as glass fiber and epoxy resin, provide advantages including higher elastic strain energy storage, superior strength-to-weight ratios, and enhanced corrosion resistance compared to steel. Consequently, the weight of leaf springs can be reduced without sacrificing performance. The steel and mono-composite leaf springs were modeled using Catia software, and their performance was evaluated using ANSYS 15.0 software.

Authors: Mohan V. , Doddapattar N. B. , Kumar K. Sunil
Published: October 2024

In particular, the impact of Silicon Carbide (SiC) particles on the mechanical properties of stir-cast Al5052 alloy Metal Matrix Composites (MMCs) for rotor blade applications is examined in this work. The goal of integrating SiC particles is to improve mechanical characteristics including wear resistance, tensile strength, and hardness while preserving the ideal weight-tostrength ratio, which is essential for rotor blade performance. The Al5052 matrix was filled with SiC in a variety of compositions (0%, 2%, 4%, 6%, and 8% by weight), and the resultant composites underwent mechanical testing and microstructural examination. Due to the efficient load transfer and reinforcing processes, the results show a considerable improvement in tensile strength and hardness with the addition of SiC particles. Furthermore, microstructural analyses demonstrate a uniform dispersion of SiC in the matrix, which supports the improved performance attributes. Wear resistance of Al5052 alloy is greatly increased when Silicon Carbide (SiC) particles are added as reinforcement. This makes the composite material perfect for applications requiring great durability and longevity to survive hard mining conditions, such as wear plates, conveyor liners, and drill bits in mining machinery components.

Published: October 2024

This study investigates the dynamics between local wisdom, cultural values, and religious values in fostering social awareness and improving student integrity. The research design is based on an explanatory model with a quantitative method approach. The results showed that religious values have no effect on student integrity; cultural values have an effect on student integrity; local wisdom has an effect on student integrity; social awareness affects student integrity; there is no effect of local wisdom on student integrity with the mediation of social awareness; social awareness is proven to indirectly mediate the effect of cultural values on student integrity; and social awareness is proven to indirectly mediate the effect of religious values on student integrity. The conclusion shows a clear relationship between local wisdom, cultural values, and religious values in their effect on student integrity; religious values alone have no effect. However, another finding is that the influence of cultural and religious values increases student integrity because social awareness has moderate effects. Social awareness has a direct effect on student integrity rather than acting as a mediator between cultural values and local wisdom. This research fills a gap in existing literature by exploring the collective effects and interactions of cultural and religious values on integrity mediated by social awareness, thereby offering insights for educational frameworks aiming to develop morally grounded and socially aware students.

Authors: Alsunaydi Ahmed
Published: October 2024

The aim of this research is to determine the prevalence of achievement goal orientations among university postgraduate students, how these orientations correlate with their grades, and how they vary based on age, gender, and stage of study. A quantitative descriptive approach was employed, surveying 320 postgraduate students from King Saud University's College of Education. The findings revealed that students had a very high mastery approach orientation, whereas their performance avoidance, performance approach, and mastery avoidance orientations were moderate. There was no significant relationship between academic achievement and performance approach orientation. However, a positive correlation was found between mastery approach orientation and academic achievement, while performance avoidance and mastery avoidance orientations showed significant negative correlations with academic achievement. The study also found that performance approach and performance avoidance orientations did not significantly differ by study stage. Conversely, significant differences were observed in the mastery approach and mastery avoidance orientations, with Ph.D. students demonstrating a higher mastery approach orientation but M.A. students demonstrating a higher mastery avoidance orientation. Male students exhibited higher performance approach and performance avoidance orientations compared to female students, although no gender differences were observed in mastery approach and mastery avoidance orientations. Additionally, older students performed better in performance avoidance orientation when the results were analyzed by age.

Authors: Imaben Ameh Francis , Enefola Jibrin Felix
Published: October 2024

The quest to maintain a balance in interstate relations, achieve collective security, and mutual support in case of war led to the formation or the emergence of the alliance system. As such, the alliance system was an unsteady and delicate system of interstate relation which started in Europe during the period of the evolution of state formation roughly between 1500 and early 1900. Although the alliance system sometimes prevent war, it was used most times to tilt the balance of power in favour of the allies. Consequently, the alliance system began to define several activities in the world ranging from economic, social, political, to cultural life. Attempts have been made to examine the alliance system and its effective attraction in conducting modern diplomacy. The study was carried out with the aid of secondary sources and internet materials. The result of the findings in this study shows that the main idea underpinning the alliance system was collective security for it was believed that since all the major European powers had strong allies, a major war could not break out since an attack on one power would lead to a counterattack not only by that country, but their allies. The paper concludes that the alliance system has had an effective attraction in conducting modern diplomacy.

A total of ninety samples of C. gariepinus were collected from several markets in Banyuwangi, namely, Kertosari, Blambangan, and Banyuwangi Kota. Using standard procedures, APC, E. coli count, Salmonella sp., V. cholerae, and chloramphenicol residues were determined. 36.37% of samples from Kertosari markets; 23.33% of samples from Banyuwangi Kota markets; and 16.67% of samples from Blambangan markets contained chloramphenicol residues, but less than 0.3 ppb. Only 40% of samples from Kertosari markets, 36.67% of samples from Banyuwangi Kota markets, and 26.67% of samples from Blambangan markets were contaminated by E. coli, but were less than 3 MPNg-1. The highest APC was from Banyuwangi Kota, followed by Kertosari and Blambangan. No samples were contaminated by Salmonella sp. and V. cholerae from any of the markets, and there was no significant difference between all markets in APC, E. coli count, or chloramphenicol residues. All farmed catfish marketed in Banyuwangi were safe to eat because no samples exceeded the maximum chloramphenicol residue and bacterial contaminant standards. Further studies are needed to detect other antibiotic residues used in aquaculture, including tetracycline, sulphonamide, enrofloxacin, and nitrofuran.

The stress level of vannamei shrimp (Litopenaeus vannamei) is affected by increased density and several genes are expressed under the condition. This study aimed to determine the expression of genes encoding white shrimp stress after density treatment and the infectious myonecrosis virus (IMNV) challenge test. A completely randomized design (CRD) was carried out with 6 treatment groups, i.e. 3 different stocking density groups without IMNV infection (100, 200, and 400 shrimp/m2) and 3 different stocking density groups + IMNV infection (100, 200, and 400 shrimp/m2). In addition, a shrimp density of 400 shrimp/m2 reported the fastest rate of developing the IMNV virus as seen from the clinical symptoms. The lowest cumulative number of shrimp deaths was at a density of 100 shrimp/m2 and was caused by the IMNV virus confirmed through RT-PCR. Expression of stress-coding genes was divided into upregulated and downregulated characteristics. The upregulated genes were lectin and translationally controlled tumor protein (TCTP), while the downregulated gene was Toll Receptor. The results showed that the expression of genes related to immunity in L. vannamei was upregulated after pathogen challenges such as lectin and TCTP, meanwhile, the Toll receptor gene was downregulated. Further study should also be performed to measure the expression of the three genes in revealing the immune pathways.

The epididymis is a crucial component of the goat's reproductive structure. The epididymis is responsible for the transportation, concentration, and maturation of sperm. This study aimed to examine the differences in the structure of macro and microanatomy, tissue composition, and the existence of androgen receptors in the epididymis of Kacang goats aged 4, 8, and 12 months. The assessment of macroscopic organ growth was done immediately after sampling, whereas microscopic measurements were carried out following histological preparations using hematoxylin-eosin (HE) and immunohistochemical (IHC) procedures. The results on the macroscopic anatomy of the epididymis indicated a significant association between age with the width of the caput dexter and sinister and the circumference of the right cauda. However, no significant relationship was found between age with the corpus length and the left cauda's circumference. Significant variations were observed in the diameter and concentration of the agglutinated spermatozoa in the lumen during histomorphometry of the epididymis in three age groups of Kacang goats. There were no statistically significant variations in the expression of androgen receptors among the three age groups. This study showed that the correlation coefficient test reveals a positive relationship between age and the caput width and corpus length dimensions, indicating that these measurements tend to grow as age increases. On the other hand, the diameter of the agglutinated spermatozoa in the epididymal lumen exhibits significant variations between the ages of 4 months, with the ages of 8 months and 12 months, suggesting that the sperm becomes fully matured by the age of 8 months.

The samples included two adults and two juvenile climbing perch from Daerah Istimewa Yogyakarta, Indonesia. The fish were euthanized using β-hydroxyethyl phenyl ether in a lethal dose. The skeleton was examined using the Alcian blue–Alizarin red whole staining, which revealed the bones and cartilage under the stereomicroscope. The result showed that the bone is the main skeleton. Cartilage was detected in the area surrounding the orbit in the adult climbing perch and in the pterotic, pterosphenoid, prootic, and distal end of the hypural, parhypural, and basal pectoral girdle in the juvenile climbing perch. Endochondral osteogenesis was found in juvenile to adult climbing perch.

Strategic infectious animal diseases have a great impact on the national economy as they may cause great economic loss, public anxiety, and high mortality. In Indonesia, among the diseases considered as strategic infectious animal diseases is foot and mouth disease (FMD). This study reported the incidence of strategic infectious animal diseases in Balongpanggang district during 2023. Throughout 2023, FMD only accounted for 4% of the total diseases of the year and was the only strategic infectious animal disease reported that year. Meanwhile, bovine ephemeral fever (BEF) incidence reached 57% (876/1546) of the total diseases in beef cattle in 2023. In addition to BEF, official veterinary services reported a total case of 1546 throughout 2023 that comprises; diarrhea (99), limping (24), helminthiasis (91), ectoparasite (11), hematochezia (3), wound (3), mastitis (4), allergy (1), dystocia (28), vaginal prolapse (11), dermatitis (45), enteritis (27), tympani (11), scabiosis (122), arthritis (67), ophthalmic problem (11), endometritis (1), uterine retention (13), indigestion (2), pneumonia (21), hypoglycemia (5), abscess (21), ovariohysterectomy (1), orchitis (1), intoxication (1), and papilloma (1). In conclusion, the only strategic infectious animal disease reported in 2023 in Balongpanggang was FMD with the incidence as high as 3% as compared to the non-strategic infectious animal diseases, BEF, which reached 54% of the total cases during 2023.

Fish productivity has long been the subject of studies using traditional Chinese medicine (TCM). To validate TCM's effectiveness on weight gain rate (WGR) and specific growth rate (SGR), a meta-analysis study was conducted. Of the 58 studies collected from PubMed, Scopus, and Cochrane Library, 4 eligible studies were analyzed quantitatively. The extracted data were then analyzed using Review Manager (RevMan) online to determine the standard mean difference (SMD), random effect, heterogeneity, and 95% confidence intervals (95% CI). As a result, TCM administration had a favorable effect on WGR (SMD = 8.33; p = 0.0001) and SGR (SMD = 8.12; p = 0.0004). In conclusion, this meta-analysis study emphasized the efficacy of TCM to improve fish production performance.
Optimization of Poultry Physiological Condition in the Post-Antibiotic Era through Nutritional Intervention – A Review
Authors: Sugiharto Sugiharto , Raza Muhammad Asif
Published: October 2024

The intestinal microbe population has a considerable impact on the physiological state of poultry. Nutritional intervention can be used to enhance the equilibrium of the gut microbiota in chickens, leading to good physiological effects. Various nutritional interventions have been implemented, including feed additives, vitamins, and fermented and functional feeds. While numerous studies have shown the efficacy of nutritional strategies, others have noted the variability of these interventions on poultry’s physiological state. Various factors can influence the effectiveness of nutritional interventions on the physiological conditions of poultry, such as the types of feed additives or active components, duration and method of administration, feed composition, environmental conditions during rearing, quality of day-old-chick, type and age of poultry, hygiene, infection, stress, and other related variables. Feed additives, when combined with nutritional components or other active chemicals, can have synergistic and complementary effects. These impacts could improve the effectiveness and reliability of the nutritional interventions on physiological parameters and poultry productivity. Furthermore, combinations can include feed additives or active components like probiotics and acidifiers, probiotics and enzymes, phytobiotics and enzymes, and plant-based materials and chitosan. The combinations show synergistic and complementary benefits, improving physiological conditions in chickens more than using feed additives or active substances alone. Overall, nutritional intervention can be used to improve the microbial balance in poultry intestines and boost their physiological state. Moreover, integrating feed additives with other active components might enhance the physiological circumstances of chickens due to the synergistic effect produced by their combination.

A 14-year-old black male Poodle was brought to the Animal Teaching Hospital, Udayana University by its owner with clinical signs of frequent licking of its left front paw. Upon examination, red bumps were observed on the left front leg, accompanied by small, round black spots scattered on the dorsal side of the body. Additionally, black nodules were present on the lower eyelids and hind limbs. Surgical intervention was undertaken to excise the tumor mass, with the animal under anesthesia induced by ketamine at 5 mg/kg BW intravenously. The reddish nodule was excised by performing an elliptical incision at the base of tumor. Postoperatively, the animal received an antibacterial injection comprising ceftriaxone and tazobactam at 25 mg/kg BW intramuscularly and antiseptic wound dressing for supportive care. Microscopic examination revealed neoplastic cells arranged into lobules of varying sizes and shapes within the tumor mass. These lobules consisted of differentiated sebocytes and basaloid cells. At the periphery of the neoplastic lobules, the basaloid cells displayed several layers and exhibited invasion with moderate anisocytosis. The mitotic index was no more than ten cells in one field of view. Based on these histopathological features, the tumor was confirmed to be a sebaceous adenoma. After a 10-month follow-up period, there were no signs of tumor recurrence observed.
