Identifying the Urgency of Indonesia's Nickel Industry Downstream: WTO Dispute and Global Momentum [Identifikasi Kepentingan Hilirisasi Industri Nikel Indonesia: Sengketa WTO dan Momentum Global]
Authors: Pattinussa Jhon Maxwell Yosua 
Published: November 2024

In recent years, Indonesia has been striving to vertically integrate its nickel industry. The primary reasons for this are technological advancements, the global momentum towards sustainability, and abundant nickel mineral resources. With 52% of the world's nickel reserves, Indonesia has undertaken the downstream policy of its nickel industry. Various policies have been created and implemented, including laws, government regulations, and ministerial regulations, to guide the downstream process. However, the European Union's lawsuit against Indonesia at the WTO has posed a significant challenge to this process. After being found guilty, Indonesia has appealed the EU's lawsuit. This research aims to identify the current state of the downstream process and the underlying interests behind Indonesia's ongoing appeal. Using qualitative research methods and focusing on explaining the downstream of the national nickel industry, this study seeks to uncover and elucidate the main agenda behind the urgency of Indonesia's nickel industry downstream amid the WTO dispute and global momentum in electronic vehicle era. Bahasa Indonesia Abstract: Dalam beberapa tahun terakhir, Indonesia telah berupaya keras untuk mengintegrasikan industri nikel mereka secara vertikal. Alasan utama dibalik hal ini adalah kemajuan teknologi yang semakin pesat, momentum global yang semakin mengarah ke berkelanjutan, dan sumber daya mineral nikel yang berlimpah. Dengan memiliki 52% dari cadangan nikel dunia, Indonesia telah menjalankan hilirisasi dalam industri nikel mereka. Berbagai kebijakan telah dibentuk dan diimplementasikan untuk menuntun proses hilirisasi, termasuk aturan hukum, aturan pemerintah, dan regulasi tingkat menteri. Namun, tuntutan hukum Uni Eropa melawan Indonesia di WTO telah memberikan ancaman signifikan terhadap proses ini. Setelah divonis bersalah, Indonesia telah mengajukan banding terhadap tuntutan hukum Uni Eropa tersebut. Penelitian ini bertujuan untuk mengidentifikasi situasi terkini dari proses hilirisasi dan kepentingan tersembunyi di balik banding Indonesia yang sedang berjalan. Dengan menggunakan metode penelitian kualitatif dan berfokus pada menjelaskan hilirisasi dari industri nikel nasional, penelitian ini mencoba mengungkapkan dan menjelaskan agenda utama di balik urgensi hilirisasi industri nikel Indonesia yang berkaitan dengan sengketa WTO dan momentum global di era kendaraan listrik.
Implementasi Hasil Konferensi Perubahan Iklim ke-26 (COP26) terhadap Pengembangan Sektor Pertambangan dan Kebijakan Lingkungan di Indonesia [The Implementation of the 26th Climate Change Conference (COP26) towards the Development of Mining Sector and Environmental Policy in Indonesia]
Authors: Then Josephine Alessia , Pratikno Roy Vincentius , Pattinussa Jhon Maxwell Yosua 
Published: November 2024

The climate change crisis triggered by the greenhouse gases emission because of the usage of coal have pushed for the establishment of UNFCCC dan the COP26 meeting, where Indonesia is actively participating. This research aims to analyze the implications of the COP26 results towards the environmental policy in Indonesia, along with the opportunities and challenges faced by the mining sector in implementing those policies. Using the neoliberal theory, qualitative approach, and case study method through secondary data analysis, this research produces two main findings. First, the COP26 results are integrated into Indonesia’s environmental policy through the roadmap towards net zero emission, constructed with the International Energy Agency (IEA). This roadmap includes the early retirement plan of coal power plants, the development of renewable energy, the super grid technology, CCS/CCUS, and the conversion of electronic vehicle. Second, even though there are some significant opportunities to achieve that commitment, Indonesia also faces huge challenges, including the coal dependency, regulation that is not optimal yet, and concerns towards improper fundings.Bahasa Indonesia Abstract: Krisis perubahan iklim yang dipicu oleh emisi gas rumah kaca akibat penggunaan batu bara telah mendorong terbentuknya UNFCCC dan pertemuan COP26, di mana Indonesia turut berperan aktif. Penelitian ini bertujuan untuk menganalisis implikasi hasil COP26 terhadap kebijakan lingkungan di Indonesia, serta tantangan dan peluang yang dihadapi sektor pertambangan dalam mengimplementasikan kebijakan tersebut. Menggunakan teori neoliberalisme, pendekatan kualitatif, dan metode studi kasus melalui analisis data sekunder, penelitian ini menghasilkan dua temuan utama. Pertama, hasil COP26 diintegrasikan ke dalam kebijakan lingkungan Indonesia melalui peta jalan menuju net zero emission, yang disusun bersama International Energy Agency (IEA). Peta jalan ini mencakup rencana pensiun dini PLTU batu bara, pengembangan energi terbarukan, teknologi super grid, CCS/CCUS, dan konversi kendaraan listrik. Kedua, meskipun ada peluang signifikan untuk merealisasikan komitmen tersebut, Indonesia juga menghadapi tantangan besar, termasuk ketergantungan pada batu bara, regulasi yang belum optimal, dan kekhawatiran terkait pendanaan yang belum memadai.
Саlculation of Cutting Tool Parameters for Production of Split Fluoroplastic Rings
Authors: Vershina G. A. , Reut L. E. , Sidorenko K. R. 
Published: November 2024

The paper considers the technological process of manufacturing fluoroplastic sealing rings, consisting in forced feeding and pulling a polymer tape blank between rotating rollers, plastic bending of the tape in the deformation zone toa given curvature by twisting it on a drive roller and the subsequent operation of cutting off the strip after obtaining a ring of the required diameter. This technology has high productivity due to the automation of the full cycle of manufacturing a split ring and the continuity of the process allowing to minimize waste, reduce the labor intensity and energy intensity of production. The most difficult issue in developing the proposed technology is the design of the working tool, its dimensions and geometry, as well as the power and kinematic parameters of the device that ensure the production of fluoroplastic rings of the required accuracy. The complexity of the issue lies in the fact that fluoroplastic has a number of features that manifest themselves during deformation, and its mechanical behavior under force exposure differs significantly from the behavior of known classical materials. However, unlike other polymers, fluoroplastic is a high-density material and has a structure with a high degree of crystallinity, therefore, as studies show, its behavior under load, as well as the mechanism and sequence of deformations in it, are in many ways similar to the behavior of metals, which allows to use methods and approaches adopted in the mechanics of solid deformable bodies for fluoroplastic. According to the proposed technology, a fluoroplastic tape blank, pulled between rotating rollers and subjected to bending in the deformation zone, experiences pure bending with the occurrence of elastic and residual deformations, of which it is the latter that give the product the necessary shape and ensure the production of a ring of the required diameter. To solve this problem, it is necessary to perform the corresponding force and geometric calculations of the process. Force calculation is aimed at determining the force parameters of bending that create the maximum possible irreversible deformations in the deformed product with the minimum possible elastic recovery (springing) after leaving the deformation zone, and the geometric calculation is aimed at fulfilling force conditions. Based on a study of the stress state during bending of fluoroplastic tape, taking into account the different rigidity of fluoroplastic under tension and compression, as well as the kinematic calculations of the elements of the working unit of the installation, the diameters of the forming roller that creates the necessary bending forces in the deformation zone and the cutting roller-caliber that ensure obtaining a ring of the required diameter are determined. The calculation methods developed by the authors are in fairly accurate agreement with the results of experimental studies.

Authors: Okereke Robyn , Karen Szauter , Nneka Ede 
Published: November 2024

Abstract

BACKGROUND
Competitive medical residency specialties, such as Dermatology, have historically placed lofty demands on applicants. We focus on the ever-increasing demands on applicants to publish, as well as discuss and quantify the delivery of these expectations in literature.
OBJECTIVE
To systematically review evidence regarding the number of publications possessed by successful applicants to a dermatology residency program.
METHODS
A systematic review of the literature was conducted between April and May 2023. PubMed, Google Scholar, and OVID were with no lower limit of the year. Our summary included 41 publications that specifically cited the number of publications by NRMP applicants successfully matching to US dermatology programs. We extracted additional applicant details (demographics, publication type) as available.
RESULTS
We found two major categories of cumulative publications reported in the literature: NRMP scholarly works and peer-reviewed indexed publications. Summarizing reports from 21 papers between 2011 and 2022, NRMP showed the overall mean amongst matched applicants to be 14.77 publications, with an upward trend over time. Throughout the literature, the mean was 3.23 peer-reviewed indexed publications for successful dermatology applicants.
CONCLUSION
Multiple studies cited and reported NRMP scholarly work numbers as “publications'', potentially contributing to discrepancies in the literature. NRMP encompasses other research endeavors in addition to peer-reviewed indexed publications in publication count. In the future, there should be greater clarification when defining and quantifying the publications of a successful dermatology applicant.

Published: November 2024

Abstract

Spinal cord injury (SCI) is one of the most devastating diseases worldwide, and its recovery is hindered by neuronal loss and formation of glial scars. In this study, we developed an injectable GelMA hydrogel loaded with neural stem cells (NSCs) and fingolimod (FTY720), in combination with electrical stimulation (ES) to promote neural regeneration as well as inhibit glial scar formation in a rat complete transected SCI model. The combined therapy of ES and injectable hydrogel incorporated with FTY720 improved both proliferation and neuronal differentiation and inhibited astrocytic differentiation of NSCs in vitro. When applied to a complete transected SCI rat model, the combined therapy significantly enhanced neuronal regeneration and reduced glial scar formation in the lesioned area, thus resulting in better motor function recovery. Taken together, our research demonstrated a promising FTY720 enhanced GelMA hydrogel loaded with NSCs for exogenous NSCs delivery and provided a novel strategy for combination therapy of SCI.

Published: November 2024

Abstract

With the rapid development of artificial intelligence and big data technology, deep learning-based bearing fault diagnosis methods have demonstrated excellent diagnostic performance. However, most neural networks require a significant amount of prior knowledge during construction and training, and a lot of time is needed to build the optimal model to achieve high classification accuracy. In addition, when it comes to fault data across operating conditions and equipment, the network's generalization ability is often limited. In addition, the scarcity of labelled fault data and the large differences in data sample distribution further increase the difficulty of achieving high-precision fault diagnosis. To address this challenge, this article focuses on rolling bearings as the main research object proposes for the first time the application of YOLOv8 in bearing fault diagnosis and proposes an improved cross condition and cross equipment fault diagnosis method RSD-YOLOv8 based on YOLOv8. Firstly, the DSConv module is introduced in the YOLOv8 network to replace the original convolutional layers, enhancing the network's ability to capture vibration signal features. Secondly, replacing the C2f module with the C2f_Rep_SimAm module reduces the number of parameters while maintaining computational efficiency. This article simulates the fault states of rolling bearings under cross-operating conditions and cross-equipment conditions using two datasets, CWRU and XJTU-SY. It verifies the effectiveness of the model improvement. In addition, transfer learning experiments were conducted on the gearbox fault dataset of Jiangsu Qianpeng Diagnostic Engineering Co., Ltd. to verify the universality of the improved model. The successful application of the YOLOv8 network in bearing fault diagnosis has provided an effective solution for diagnosing bearings under different operating conditions and equipment.

Published: November 2024

Abstract

Background: Ehrlichiaspp. are a group of intracellular parasitic bacteria primarily transmitted by ticks and exhibit a wide global distribution. Their ability to infect a diverse range of mammals, including humans, underscores their immense public health significance.
Methods: We collected tick and dog blood samples in different areas of Hainan Province. The species of ticks were identified by standard PCR of the tick 16S rRNA gene. Detection of Ehrlichiainfection in ticks and dogs using nested PCR of the 16S rRNA gene of Ehrlichia spp.. The obtained sequences were subjected to comparison with other sequences cataloged in GenBank. Subsequently, risk factors affecting Ehrlichiainfection were statistically analysed.
Results: All 631 ticks belonged to the Rhipicephalus linnaei; 63 (9.98%) out of 631 ticks tested positive for Ehrlichia canis, while 140 (11.08%) out of 1264 dog blood samples were positive for E. canis. Notably, Ehrlichia ewingii and Ehrlichia chaffeensiswere not detected. The prevalence of Ehrlichia infection in dogs is correlated with factors such as age, breed, dewormer use, tick infestation, and living environment, while displaying no association with the gender of the dog.
Conclusions: In Hainan Province, Rhipicephalus linnaei is the dominant tick species infecting dogs. Dogs are vulnerable to Ehrlichia infection, particularly rural and stray dogs.

Published: November 2024

Abstract

Several conceptual nanodevices based on the four-atom-layer α- and β-Ge2Y2 are constructed, and their electronic transport and photoelectronic properties are revealed by means of first-principles calculations. Our results demonstrate that the Ge2Y2-based p-n junction diodes show a great rectifying effect with high rectification ratio. Their p-i-n junction transistors show a field-effect behavior with better rectifying effect and stronger electronical anisotropy. Moreover, the Ge2Y2 monolayers have strong photoelectronic response in the visible light region, displaying excellent photoelectronic properties in the photovoltaic materials and photoelectronic transistors. Our findings uncover the multi-functional features of four-atom-layer Ge2Y2 monolayers, promising their extensive applications as candidates for future flexible semiconductor devices.

Abstract

Background:
Primary healthcare centers are essential for community care, with family medicine (FM) residents playing a key role. Their performance and interpersonal skills impact patient experience and assessing healthcare worker satisfaction provides a fuller view of resident competency beyond supervisor feedback.
Aim:
This research assesses healthcare worker satisfaction with family medicine residents in primary healthcare centers, identifying challenges affecting patient care and resident education to improve overall center effectiveness.
Methods:
We conducted a three-month quantitative, cross-sectional study using questionnaires in primary healthcare centers within Riyadh's second health cluster, targeting a representative sample of healthcare workers, including nurses, technicians, administrative staff, and others in Saudi Commission of Health Specialties (SCFHS) accredited family medicine residency centers.
Results:
The majority of study participants are female 104 (68.9%), Saudi 148 (98%), and aged 30–39 73 (48.3%). Over half hold diplomas 82 (54.3%), with nurses being the largest group 93 (61.6%). Job experience is mostly 11–20 years 88 (58.9%). Reliability is high (Cronbach's alpha > 0.85). Participants agree residents respond well and show empathy. ANOVA reveals significant differences in satisfaction based on job experience for performance (p = 0.026) and conduct (p = 0.071), but not interpersonal skills. Satisfaction does not vary by education, nationality, or specialty, with average scores of 4.14 for performance, 4.38 for conduct, and 4.22 for interpersonal skills.
Conclusion:
The study found high satisfaction among predominantly female Saudi healthcare workers regarding family medicine residents' performance and interpersonal skills. Job experiences influence satisfaction, but education and specialty do not significantly affect perceptions. These positive scores highlight the need for strong collaboration between healthcare workers and residents to enhance patient care and the educational environment.

Published: November 2024

Abstract

The aim of this work is to evaluate different methods of obtaining nanocellulose from an agro-industrial residue, using yerba mate sticks (YM) as raw material, through chemical and mechanical processes, such as bleaching (B), ionic liquid (IL) and steam explosion (S). Nanocellulose was characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), and dynamic light scattering (DLS). The XRD results showed that the samples YM-SBIL and YM-SIL presented 50.23% 43.06% of crystallinity for cellulose II, respectively. FTIR of YM-SIL showed peaks with greater intensity in regions related to bonds from cellulose II, also seen by TGA. DLS results demonstrated that the size distribution below 100 nm was above 60% in all treated YM samples. Steam explosion, bleaching and IL treatments brought the YM fibers closer to the characteristics of commercial cellulose fibers (CC), suggesting that the treatments were effective in reducing components such as hemicellulose and lignin. The addition of the chemical bleaching did not show considerable differences to the IL treatment, indicating that IL can be a viable option for obtaining nanocellulose.
