Realism’s Timeless Wisdom and its Relevance for the Global South
Authors: BECKMANN Nicolas Alexander , ERPUL Onur 
Published: January 2024

Since the numerous calls for developing a truly global and plural IR discipline,
a growing spate of IR studies have sought to contextualize and critique the
Euro-centeredness of the field. One of the most significant problems scholars
have pointed out is the hegemonic status of Anglo-American IR theories, which
seemingly assert an ontological preeminence and universality at the expense of
local knowledge and homegrown theories. While the present article shares many
of global IR’s concerns, it nevertheless proposes that in our quest to teach IR
and develop homegrown theories, we should not lose sight of the importance
of traditional contributions to the field. Our argument is based on a series of
reflections about the relevance of realist scholarship for the developing world.
Through an analysis of the major criticisms of classical IR theories, we seek to
show that classical and, to a lesser extent, structural and neoclassical realism
contain several and diverse arguments that speak directly to audiences in
the global South. Classical realism, in particular, shares some interesting
commonalities with postcolonial theory, which could pave the way for a more
systematic engagement between the two approaches. Therefore, we argue that
a global IR founded primarily on critiquing classical theories would be an
impoverished IR, and “the thousand small steps” to a globalized discipline ought
not neglect the valuable insights and reflections of traditional theory.
ANALISIS LAJU DEFORMASI PAHAT CARBIDE PADA SIMULASI PEMBUBUTAN BAJA ST41 DENGAN MESIN BUBUT KONVENSIONAL MENGGUNAKAN SOFTWARE ANSYS
Authors: Ulin Nuha  , Golwa Gian Villany 
Published: January 2024

In the machining process, knowledge of the tool and workpiece is required to achieve maximum results between quality and productivity. Tool wear parameters are very important to know because the process of changing or sharpening the tool can be predicted. One thing that influences the tool wear rate is the friction force between the tool and the workpiece. This frictional force will produce vibrations and heat energy, causing the chisel grains to erode so that they will experience wear within certain standards. This research aims to analyze the wear value of carbide-type tool edges in the ST41 material turning process based on the friction force that occurs between the tool and the workpiece. Then, from the wear value, the recommended cutting speed is. The method used is simulation-based research using ANSYS software, especially ANSYS Mechanical, by entering predetermined parameters, including diameter and spindle rotation. From the simulation results, the total deformation of workpieces with diameters of 25 mm, 35 mm and 45 mm is 0.363 μm, 0.155 μm and 0.152 μm, respectively. It can be concluded from the simulation results that the largest total deformation is at a diameter of 25 mm.
An Optimization Analysis of the Melt-Cutting Diversion Jetting Mechanism for Downhole Drilling Columns
Authors: Jing Jun , Luo Xirui , Zhu Xiaohua , Peng Yang , Shan Hongbin 
Published: January 2024

Summary
Molten metal jet cutting, based on the transient superexothermic characteristics of aluminum thermal reaction, presents a novel technology for swiftly cutting and disposing of stuck drilling columns in downhole oil and gas wells. The key to achieving efficient cutting in drilling columns lies in the jetting mechanism, which guides the high-speed radial ejection of aluminum thermal reaction products that act upon the metal pipe wall. This study uses computational fluid dynamics (CFD) simulation to establish a fluid domain model for the process of cutting molten drilling columns. The optimization of the jetting mechanism is conducted to improve the circumferential coverage by the molten metal by analyzing the impact of molten metal yield and jetting mechanism parameters (cone angle of the conical conductor, diameter, number and length of nozzles, and shape of the diverter). Finally, an ejection test is carried out to verify the optimized jetting mechanism. Research results show that increasing the cone angle of the conical conductor can increase the flow rate of the molten metal at the upper end of the axial nozzle assembly to smoothly discharge the molten metal. Increasing the number of nozzles with equal diameters can increase the circumferential distribution range of molten metal ejected into the cutting area. However, the molten metal circumferential coverage will be impacted by increasing cutting distance. Increasing the nozzle size can reduce the divergence of the molten metal, thereby improving the coverage of the molten metal in the cutting area. When the nozzle arc length L = 8 mm, the molten metal can cover almost the entire cutting area. Adding a 2-mm horizontal draining table at the end of the diverter can assist the molten metal in changing its flow direction, allowing the molten metal to be ejected in a radial direction. The research results provide a theoretical basis for optimizing fusion cutting tools and formulating cutting processes.
Genetic Insights into Plasmodium falciparum Resistance to Sulfadoxine-Pyrimethamine through a Study of the 540-dihydropteroate synthetase gene Mutations in Jos, Nigeria

Published: January 2024

Abstract
Aims: To investigate mutations in the 540-dihydropteroate synthetase (540dhps) gene, specifically at codon 540, that may confer resistance to sulfadoxine-pyrimethamine treatment by Plasmodium falciparum in Jos.
Study design: This cross-sectional study.
Place and Duration of Study: The samples for this study were gathered in Jos, Plateau State, Nigeria, between October 2019 and January 2021.
Methodology: One hundred malaria cases were assessed, and parasite DNA was extracted from whole blood samples using Zymo extraction kits. PCR and gel electrophoresis identified the Plasmodium genus and Plasmodium falciparum, along with the 540-dihydropteroate synthetase gene. Sanger sequencing and bioinformatics analyses (nucleotide blast, blastx, and query-anchored alignment view with dot of the NCBI tool) were employed.
Results: Results revealed that 50% of the tested samples were positive for the Plasmodium genus, with 96% identified as Plasmodium falciparum. Point mutations were found in the 540dhps gene at codon K540E in 16.67% of the samples. Interestingly, while a nucleotide mutation occurred in the DNA's coding region, it did not translate into amino acid changes, indicating no likely impact on the protein's functionality.
Conclusion: This study highlights the prevailing presence of Plasmodium falciparum in Jos, with a significant 96% prevalence among malaria patients. Contrary to the previously reported mutations at codon K540E on 540dhps, the mutation observed in the nucleotide sequence in our findings did not affect the amino acid sequence, suggesting that this mutation may not be associated with the literature previously reported on resistance to sulfadoxine-pyrimethamine drug

Published: January 2024

Abstract

Based on data from the BPBD Malang Regency, more than 100 geological disasters, such as earthquakes, landslides, and subsidence, yearly with losses of up to 3 Billion IDR. Based on field observations, one of the villages that frequently experience landslides and subsidence almost every year is Srimulyo Village, Dampit District. This condition requires research on the subsurface to analyze the trigger factors for geological disasters to increase disaster mitigation and awareness. This study aims to analyze the typological characteristics of the rocks in the study area using the geomagnetic method as a geological disaster mitigation strategy. The method is geomagnetic; measurement designs regularly cover the entire study area with a distance of 300 meters between measurement points, while research is presented in 2D models and the analysis is based on the measured magnetic anomaly values on the reduce to pole (RTP) map. The results showed that the correlation between the RTP maps, regional geology, and field observations gave mutually correlated results. Based on the interpretation result of the RTP map, we create a Disaster Risk Zone map marked with the highest magnetic anomaly values in the northwest and northeast areas. The types of disasters in this zone vary, such as landslides, ground movements, and earthquake damage. The meeting between compact rock layers with sandy clay layers and faults causes rocks that were originally stable to become unstable, so the potential for disaster is large. The results of this study contribute to the local government in carrying out disaster mitigation and development planning.
The leaf litterfall patterns of Alnus alnobetula subsp. maximowiczii Chery at the timberline of Mt. Fuji, central Japan
Authors: Sakio Hitoshi , Masuzawa Takehiro 
Published: January 2024

Abstract
Alnus alnobetula subsp. maximowiczii Chery is a dwarf shrub found at the timberline of Mt. Fuji. This species has been suggested to promote soil eutrophication in two ways: it can fix aerial nitrogen through symbiosis with nitrogen-fixing bacteria in its root system, and its fallen leaves are rich in nitrogen. In this study, we investigated the defoliation and leaf dispersal pattern of A. alnobetula subsp. maximowiczii at the timberline of Mt. Fuji. The petioles of all leaves of A. alnobetula in the research plots were marked with vinyl tape. The marked leaves were collected in November, when all leaves had fallen, and their locations were recorded. We found that leaf litter of this species was scattered above the dwarf shrub community, with the distribution of fallen leaves likely influenced by prevailing winds. The fallen leaves trapped in herbaceous patches above the timberline may contribute to soil eutrophication and accelerate the upward elevational movement of the timberline.

Authors: Marsia Shayan , Kamran Alishba , Shah Sayed Mustafa Mahmood , Merchant Rameez Ali , Abbas Shan E 
Published: January 2024

Abstract
Background: Program websites are essential resources in the process of residency and fellowship application. We evaluated the information furnished on these resources by Epilepsy fellowship programs. The extent of information provided was compared across geographic zones, academic affiliation, and national ranking.
Methods: A list of Epilepsy fellowship programs was derived from the Fellowship and Residency Electronic Interactive Database (FREIDA). Links to program websites were obtained directly from FREIDA or using Google’s search engine. Online data was categorized to reflect program information, education, recruitment, compensation, epilepsy center-specific information, and social media presence. Data points under each category were collected to develop a standardized scoring system. The frequency of criterion present was compared across geographic zones, academic affiliation, and national ranking using parametric and non-parametric statistical tests. Significance was determined at a p-value ≤0.05 for all cases. The study utilized IBM SPSS version 28 and Python 3.11.3.
Results: We analyzed 80 Epilepsy fellowship programs. The most reported feature was the program director’s name and email (100.0%). The least reported features included board pass rates (1.3%), preparatory boot camp (8.8%), and post-fellowship placements (11.3%). Programs were found to be well-represented on Twitter (88.8%), Facebook (81.3%), and Instagram (71.3%). Most (85.0%) of the programs were searchable through Google. The scores for program information, education, recruitment, compensation, epilepsy center-specific information, and social media visibility did not significantly vary based on location, academic affiliation, or rank status.
Conclusions: Our results demonstrate that despite an online presence, there is much room for improvement in the content available to the applicant. To improve the Match process and attract a roster of well-informed fellows, Epilepsy fellowship programs should furnish program websites with up-to-date information relevant to program information, education, recruitment, compensation, and epilepsy center-specific information.
Challenging Steroid Shift in Neuronavigation - A clinical study proposal
Authors: Roy Amrit , Maschke Svenja , Warade Abhijit , Misra Basant Kumar 
Published: January 2024

Abstract
The intraoperative orientation for neurosurgeons is routinely aided by tools such as neuronavigation. For this purpose, imaging data of the head are referenced to the patient's fixed head with the aid of electromagnetically or optically recorded surface points. However, a certain susceptibility for inaccuracy remains.
Steroids such as dexamethasone are routinely given to reduce perifocal edema. Clinical improvement as well as reduction of edema can be observed radiologically just hours after steroid application – also making it a preoperative potential source of metric inaccuracy.
The effect of steroids on tissue and tumoral shift on neuronavigation has not been quantified to date. While there are several reasons for navigation inacurracy, this type of shift is often forgotten and not accounted for, but could be easily corrected. We propose the need to perform an additional preoperative cranial MRI (cMRI) shortly before the biopsy/resection in patients who have received steroids due to perifocal cerebral edema to (1) quantify and (2) compensate for steroid induced tumor shift and thereby improve inaccuracies of neuronavigation.
Intelligent control algorithm for industrial robots when performing the assembly operation of cylindrical non-rigid parts
Authors: Vartanov Mikhail Vladimirovich , Nguyen Van Linh , Kogan Efim Alexandrovich , Dao Van Luu 
Published: January 2024

Abstract

When developing robotic assembly technology, it is necessary to use intelligent algorithms that control the assembly process online. One of the tasks that has been little studied so far is the assembly of cylindrical non-rigid parts. Mathematical models of the coupling stages during robotic assembly have been developed, which are necessary for the identification of the signals of the force-torque sensor. The obtained analytical solutions make it possible to determine the conditions for the occurrence of jamming of the non-rigid shaft during two-point contact during the coupling of the shaft with a rigid sleeve. The obtained values of deflections and angles of rotation allow us to correct the movement of the output link of the robot during the assembly operation. A mathematical model is presented for solving the problem of determining the current contact state (CS) during assembly using the support vector machine (SVM) method when obtaining information about the position coordinates by the control system of an industrial robot and forces from a force-torque sensor. The algorithm was tested on an IRB-140 industrial robot with an IRC5 controller equipped with an FTN-AXIA80 SI500-20 Ethernet force-torque sensor from Schunk.
