Published: March 2024

Although the joining processes of plastics are typically carried out through welding, adhesive bonding, or mechanical fastening elements, the production of complex and large parts often requires welding technology. In this study, the effect of part infill ratio (20%, 40%, 60%, 80%, and 100%) on the welding strength of 3D printed PLA Plus parts was evaluated through friction stir welding (FSW). Tensile tests and temperature measurements were carried out to examine the effects of friction stir welding process parameters (feed rate: 50 and 100 mm/min and rotational speed: 1000 and 1500 rpm) on the structure and mechanical properties of friction stir welding. Moreover, visual inspections were performed to detect defects in the weld zone. Compared to the PLA Plus samples given as reference according to the infill ratios, the highest welding strengths were obtained at 80%, 60% and 100% infill ratios (29.4 MPa, 17.47 MPa and 41.12 MPa and 112.38%, 97.48%, 87.04% efficiency, respectively). As a result, it was determined that at low infill ratios (20% and 40%), the weld quality was negatively affected, and a surface tunnel defect occurred in the weld zone. It has been determined that the weld quality in FSW is significantly affected by the temperature occurring during the process. The study has shown that parts printed at different infill ratios, especially on a 3D printer, can be combined with friction stir welding and that the efficiency of the welding process can be increased by optimizing the infill ratios.

Published: March 2024

Ceramic reinforced metal matrix composite (CMMC) cams in engines could improve fuel efficiency and wear resistance compared to traditional steel cams but require absolute evaluation. However, ensuring safe CMMC cam operation demands extensive wear testing, mimicking real-world conditions over longer durations instead of limited lab evaluations. This study is an extension of the previously reported feasibility analysis of the ceramic particle reinforced Al matrix composite labs. The performance of the best selected (Al + 20, 30 vol. % SiC(2µm)) composites for a wear duration of 2.5, 5, 7.5, and 15 h is reported with various combinations of pressures and compared with the reference cam lobes. Results showed that the higher content of ceramic particles improved the wear resistance, however, the influence diminished at larger durations due to surface hardening of the composites. The wear performance of the composite (Al + 30 vol.% SiC) reaches 73% of the conventional cams but it also causes significant wear in the counterface due to initiation of three-body-wear by the dislodged ceramic particles.

Published: March 2024

There are numerous ways for the younger generation to participate in politics, but there are evidence that they are unwilling to join (anti-politics). This study tries to expose two things: (1) the causes of this trend, and (2) remedies to support smooth political circulation in Indonesia as a democratic country. This study accomplishes this purpose by employing Fairclough's Critical Discourse Analysis (CDA). Data acquired from the controversial documentary Sexy Killer's netnography on YouTube. This study highlights several significant findings, particularly the ambivalence and conflict between reality and ideals in today's youth and society. They are skeptical of the earnestness and dedication of government leaders elected through a democratic political process. At the same time, people expect government personnel to carry out their responsibilities. The implications of this study's findings are a criticism of the political education model, which has so far prioritized practical factors above theoretical aspects (content, composition, and proportion).

Published: March 2024

Microplastics in the Central Citarum River, Karawang, West Java, originate from anthropogenic activities of people living around the watershed, which is an industrial, agricultural, and densely populated residential area. Microplastics are degraded plastics < 5 mm in size. This study aims to determine the abundance and size of microplastics in the Middle Citarum River, through observation with a microscope. Sampling was conducted at three locations with three observations: February, March, and April 2022. The types of microplastics found were pellets, films, fibers, and fragments. Microplastic particle size < 0.3 mm was the most common size found. The abundance of microplastics in the water of the Middle section of the Citarum River is different at each sampling location. The total number of microplastic particles in all research locations was 4,413 particles. The highest abundance of microplastics in all sampling locations was in densely populated residential areas at 239.7 ± 326.7 particles/m3 , followed by agricultural areas with an abundance of 72.5 ± 63.8 particles/m3 , then the lowest abundance was in industrial areas at 55.6 ± 57.8 particles/m3. The average abundance of microplastics in the middle Citarum River water was 122.6 ± 209.7 particles/m3. Statistical analysis using Kruskall Wallis with a df value of 2 > 0.05 showed no significant difference in microplastic abundance at each research location. All stations had the same potential for microplastic pollution. This study shows that high anthropogenic activities lead to high microplastic pollution in water. Therefore, proper mitigation and management of waste and plastic waste are needed.

Water shortage is a complex issue with severe implications for human well-being, agriculture, and ecosystems. Climate change, population growth, and inadequate water management practices contribute to this global problem. This study is to identify the causes of ground water scarcity and determine groundwater potential zones in the Abuja community. The research area's borehole coordinates, Landsat 8 satellite imagery, AsterDEM 30m resolution DEM data, and vertical electrical sounding (VES) data were all used to do this. Unsupervised classification of Landsat imagery was used to create a layer of land use and cover, image filtering techniques were used to improve the visualization of lineament extraction, and density analysis was used to quantify lineament density. AsterDEM data was subjected to surface analysis to acquire elevation data, while VES data were interpolated to produce spatial distributions of the resistivity and thickness parameters. To identify groundwater potential zones, multiple criterion analysis using the analytical hierarchical process (AHP) was utilized to reclassify variables such as land use, elevation, lineament density, resistivity, and thickness. To create the zones, these characteristics were weighted and layered. According to the findings, resistivity levels varied from 6.25 m to 676 m, and the geologic ground structure's thickness ranged from 0.27 m to 92.37 m. Elevation varied from 41 meters to 720 meters, while lineament density ranged from 0 to 0.04. 74% of the land was categorized as vegetated, 21% as built up, 2.7% as water bodies, and 2.3% as rock formations. Within Abuja, zones of groundwater potential were identified as being very low (5%), low (26.7%), marginally high (26.3%), moderately high (28.5%), and very high (13.4%)

This review paper highlights the role of phytocannabinoids in controlling triple-negative breast cancer (TNBC). Triple-negative breast cancer (TNBC) is a specific subtype of breast cancer that does not express estrogen receptor (ER), progesterone receptor (PR), or human epidermal growth factor receptor 2 (HER-2), which has clinical features that include high invasiveness, high metastatic potential, proneness to relapse, and poor prognosis. TNBC is one of the most aggressive subtypes of breast cancer that is often associated with poor patient outcomes because of the development of metastases in secondary organisms like in the brain, bone, and lungs. Triple-negative breast cancer (TNBC) is a kind of breast cancer that does not have any of the receptors that are commonly found in breast cancer. The highest number of TNBC cases has been recorded in India. Currently, TNBC is highly prevalent among Indian women and develops approximately 20% to 43% of all patients with breast cancer. Triple-negative breast cancer (TNBC) is an aggressive malignancy that requires effective targeted drug therapy. Patients with TNBC develop metastasis and recurrence over time and have reduced survival compared to patients with other subtypes of breast cancer. Pre-clinical studies have demonstrated that phytocannabinoids exert important antitumor properties in the main breast cancer subtypes, particularly in TNBC, where different phytocannabinoids and synthetic cannabinoids have shown interesting therapeutic actions. Neither CBD nor THC are universally efficacious in reducing cancer cell viability. Focusing on in vitro studies, the effect of CBD on cancer cell viability ranges from no effect, to a modest reduction, and to significant cytotoxicity depending on concentrations, cancer cell lines, cell growth conditions, the performed assays, and the time of CBD exposure. However, it should also be noted that research into the efficacy, dosage and drug safety of cannabinoids in tumor therapy still has a long way to go, especially with regard to human clinical trials to be conducted, through which alone the benefits and advantages for cancer patients but also possible risks can be defined.

The risk level of natural disasters such as earthquakes depends on many factors. Some of these are direct hazards, while others are vulnerability factors that increase the risk. In this regard, risk assessment should be performed by evaluating the hazard and vulnerability factors together. The Analytical Hierarchy Process (AHP) is a powerful tool for co-evaluating such multiple decision criteria. The spatial visualization of the results facilitates the direct assessment of risks as well. In the present study, the seismic risk assessment of the Bitlis province in Eastern Anatolia, which has a high seismic risk, was performed by using the GIS-based AHP method. Among many criteria, six effective criteria on earthquake risk such as seismicity, demographic and topographic criteria were taken into consideration based on expert decision makers. It is concluded that the results obtained from the study were quite successful in terms of determining the seismic risks of the study area. Accordingly, while the risks are high in densely populated settlements with high peak ground acceleration (PGA), the risk decreases according to soil and land use.
Adaptive Advanced Emergency Braking on Combined Road Friction Coefficients
Authors: Şahin Hasan
Published: March 2024

In this study, an Advanced Emergency Braking System (AEBS) is adopted to the combined road friction coefficients by proposing an emergency steering maneuver. AEBS is one of the significant driver assistant systems to avoid rear-end collisions. AEBS supports the drivers with acoustic and optical warnings before applying the full braking maneuver. However, in special cases, such as the sudden decrease of road friction coefficient during braking, a single hard braking maneuver without a proper steering assist may not be sufficient to prevent a rear-end collision. Therefore, AEBS may work with the autonomous emergency steering systems to prevent inevitable rear-end collisions. The originality of this study arises from the necessity of the adaptation of the AEBS to work in cooperation with the autonomous emergency steering systems. A predictive controller was used to support the emergency braking maneuver with an autonomous steering maneuver via observing the yaw rate of the vehicle. The predictive controller was developed in MATLAB software. The implementation of the controller was performed in a non-linear four-wheel vehicle model in the IPG/CarMaker simulation environment. The communication between the simulation environment and MATLAB software was established in the Simulink interface of MATLAB. The results proved that the predictive controller maintained the vehicle lateral stability without causing any type of collisions.
