Authors: Shahrullah Rina Shahriyani , Syarief Elza , Hariyanto Jerry
Published: September 2024

AbstractThe development of information and technology has brought the economy to a new stage known as e-commerce. The presence of e-commerce also presents a new problem in society, namely the presence of a disclaimer. To examine these problems, this research uses normative legal research methods. This research shows that the disclaimer is a form of standard clause. As a form of e-commerce consumer protection, the standard clause must comply with the provisions regarding standard clauses as stipulated in statutory regulations. In Indonesia, e-commerce is regulated in Law No. 19 of 2016 concerning Electronic Information and Transactions. So, the implementation of the disclaimer in e-commerce transactions must be adjusted to the existing laws in Indonesia. Keywords: E-Commerce; Disclaimer; Consumer Legal Protection.

The skin mucus of the rice eel (Monopterus albus) contains various antibacterial compounds and has the potential as a synthetic antibiotic. This research was conducted to explore the potential antibacterial power of the rice eel skin mucus against some pathogenic bacteria in freshwater fish. The bacteria were isolated from five samples of rice eel cultivation ponds belonging to Mr. Sabwan and then challenged with the mucus of the eel's skin through diffusion tests using paper discs. The rice eel skin mucus tested its antibacterial activity against three species of freshwater bacteria, Aeromonas hydrophila, Escherichia coli, and Staphylococcus aureus, by testing sensitivity and inhibitory zones. The inhibitory zones of each bacterium were measured using Vernier caliper which refers to the standardization of the inhibitory zone: < 4 mm no activity, 5-9 mm weak, 10- 14 mm medium, and > 15 mm strong. Test results showed that the eels' skin mucus could inhibit the growth of bacteria Aeromonas hydrophila, Escherichia coli, and Staphylococcus aureus.

Published: September 2024

The global SARS-CoV-2 pandemic is impacting public health and living systems. Edible Bird's Nest (EBN), one of the variants of Swallow's Nest (SBW), is recognized as a medicinal food. The potential of SBW as a therapeutic agent is gaining attention due to its ability to inhibit viral hemagglutination activity. This study provides information on the prediction of SBW demand in the coming year so that it can contribute to determining Indonesia's SBW export performance. Net weight data (tons) of SBW export time series were obtained for 10 years from 2012 to 2022 in 10 countries, namely: Hong Kong, China, Singapore, USA, Vietnam, Canada, Taiwan, Thailand, Japan, and Cambodia, combined with laboratory examination on nitrite levels conducted at the Surabaya Agricultural Quarantine Center, Indonesia. This study shows the minimum limit on nitrite levels in SBW exports and the need for SBW exports in the next four years. One of the requirements for SBW exports is the minimum limit of nitrite levels. The ARIMA method has been implemented to forecast SBW export demand in 10 countries for the next four years. SBW export demand in the next four years is expected to decline. The findings make a significant contribution as a source of information for decision-makers involved in SBW export activities.

Authors: Fadhilla Taqwa Sultan , Syah Nanda Yulian
Published: September 2024

Pyometra commonly occurs in female cats. There are two types of pyometra: open pyometra and closed pyometra. Open pyometra refers to purulent and bloody discharge from the vulva, while closed pyometra does not have any vaginal discharge; however, there is an enlarged abdomen from the fluid-filled uterus. A 2-year-old Persian queen with an enlargement abdomen was clinically diagnosed with open pyometra as there was vaginal discharge. Additional examination, such as ultrasonography, was also performed to establish the diagnosis. Using ultrasonography, hyperechoic imaging clearly showed in the uterine lumen of the uterus. Based on the following examinations, an ovariohysterectomy was performed to eliminate the source of infection. Anti-inflammatory and antibiotic drugs were administered post-surgery, and the patient fully recovered after one week of intensive care.
Intercellular transfer of multidrug resistance mediated by extracellular vesicles
Authors: Yang Anxiang , Sun Hui , Wang Xiaokun
Published: September 2024

Multidrug resistance (MDR) poses a formidable obstacle in cancer treatment, enabling cancer cells to evade the cytotoxic effects of chemotherapeutic drugs through various mechanisms. These mechanisms include intrinsic resistance, which is present prior to treatment, and acquired resistance, which develops after exposure to chemotherapy agents. Small membrane-bound vesicles, known as extracellular vesicles (EVs), are crucial in intercellular signaling as they transport bioactive molecules that can modify the characteristics and functions of recipient cells. Recent research highlights EVs as pivotal players in fostering drug resistance. This review focuses on the intercellular transfer of MDR from donor cells to susceptible recipient cells through specific cargo in EVs, such as ATP-binding cassette (ABC) transporter proteins, nucleic acids, and other regulatory factors. Additionally, the features of intercellular communication mediated by EVs are also discussed. Gaining insight into these mechanisms is essential for developing strategies to counteract resistance and improve the effectiveness of cancer treatments.
Смуго-пропускні фільтри зі збільшеною до (3N+1) кількістю полюсів згасання
Authors: Літвінцев Сергій Миколайович , Захаров Олександр Віталійович
Published: September 2024

Завдяки перехресним та змішаним зв’язкам, у смуго-пропускному фільтрі (СПФ) N-го порядку з резонаторами паралельного типу може бути реалізовано (N + 1) нулів передачі (НП), розташованих на комплексній площині s = σ + jω. НП розташовані на дійсних частотах (вісь jω) також називають полюсами згасання (ПЗ). У статті розглянуто альтернативну можливість формування ПЗ у фільтрах за рахунок використання резонаторів з особливими властивостями, що призводить до суттєвого збільшення числа ПЗ з (N + 1) до (3N + 1). Збільшення числа ПЗ при меншій кількості резонаторів, дозволяє збільшити селективність і рівень режекції, а також зменшити втрати, що вносяться в СПФ. Особливі властивості резонаторів полягають у тому, що їх вхідна провідність Y має один або два полюси (ωp1, ωp2), розташованих поруч з резонансною частотою ω0, що призводить до появи ПЗ в СПФ. Запропоновано та проаналізовано три резонатори із зазначеними властивостями. Вони утворені каскадним з’єднанням чвертьхвильового резонатора та зосереджених елементів L і C. Вхід резонаторів розташовується з боку зосереджених елементів. Встановлено, що добротності QL і QC зосереджених елементів не впливають на втрати фільтра в смузі пропускання, що вносяться, оскільки зменшення QL і QC призводить тільки до зменшення «глибини» ПЗ. Вперше в експериментальному мікросмужковому СПФ другого порядку реалізовано 7 ПЗ.

Sustainability Education in Formal and Non-Formal Education Materials. A Scoping Review
Authors: Stylianou Paschalina
Published: September 2024

Education for sustainable development seeks transformative learning in order to empower learners to change the ways they understand the world. In order to achieve its goals, teaching materials are needed, that reflect its principles and goals in their content and pedagogy they promote. The study of the epistemological background on which the teaching material is structured is a research proposal, which is addressed to researchers, authors and practitioners for sustainable development, pointing out that the structuring and development of the materials should be based on a theoretical framework that effectively link the teaching activity with all 17 Sustainable Development Goals with a focus on Quality Education. This scoping review attempts to map the existing literature that assesses the effectiveness of formal and non-formal educational materials that seek to promote education for sustainability. In addition, research is presented that evaluates the effectiveness of teaching materials from the perspective of sociocultural learning theory, considering that education for sustainable development (an ideal to be achieved) is in a dynamic relationship with constructivism (a learning theory) on the basis of knowledge construction, learning and sustainability's sociocultural aspects. It was found that the international literature investigating the contradictions presented by educational materials in relation to the objectives they set and achieve and the way in which the activities they propose are implemented in practice, is limited.

Published: September 2024

The concept of Bhinneka Tunggal Ika exemplifies the diversity of Indonesia while emphasizing its ability to harmoniously unite these differences. However, today conflicts often arise in society caused by differences. The inculcation of multiculturalism in education in schools is thus essential, especially regarding the character of tolerance. Therefore, Research and Development (R&D) research was carried out with the ADDIE development model, which aims to develop and produce ICIMAI comics that link examples of intolerant everyday practices with Islamic values, expected to help improve the tolerance character of students. The development involved media experts, material experts, practitioners, or teachers who evaluated the product. In addition, product tests were also conducted on a limited scale and in the field, each of which involved elementary school students. The results revealed that experts and practitioners declared that the product is in the "Very Good" category, so it is feasible and valid. Students on the limited scale test gave a positive response. The tolerance character of students also experienced an increase, as indicated by a significant increase in tolerance scores after the intervention using ICIMAI comics.

Authors: Xu Wei , Zhou Shangbin , Bai Danyang , Wang Pengru , Xu Gan , Yuan Hao , Li Bo , Xiao Jianru
Published: September 2024

Background:

Solitary spinal metastasis (SM) is one of the indications for total en bloc spondylectomy (TES). Conventional TES carries the risk of damage to the great vessels anterior to the vertebral column, mainly because of a lack of visualization of the anterior structures. In this study, we devised a modified standard TES technique to achieve direct visualization in a 1-stage posterior approach.

Methods:

Included in this study were patients ≥18 years old with solitary thoracic or lumbar SM who underwent the modified standard TES at our institution between January 2017 and October 2022. Patient data were retrospectively sourced from medical records, and patients had a minimum of 3 months of postoperative follow-up.

Results:

This study involved 71 East Asian patients (median age, 57 years; 34 males), comprising 38 patients with thoracic SM and 33 with lumbar SM. Lung cancer was the most common tumor histology. Fourteen patients (19.7%) experienced intraoperative complications; pleural rupture was the predominant complication, and there were no cases of injury to the spinal cord or great vessels. The median operative time was 305 minutes (range, 203 to 660 minutes). The median intraoperative blood loss was 1,000 mL (range, 400 to 4,000 mL). The median perioperative blood transfusion was 4 units (range, 0 to 12 units), and the median hospitalization duration was 17 days (range, 14 to 29 days). Additionally, 27 patients (38.0%) had acute (perioperative) complications. Seven patients were lost to follow-up. Significant clinical improvement was achieved 3 months postoperatively. Postoperative early and late complications were observed in 5 patients. Of the 64 patients with completed follow-up, 47 (73.4%) had negative surgical margins, and none received postoperative radiation therapy. Revision surgery for local tumor recurrence was performed in 4.7% of patients. The median follow-up was 31.5 months (range, 3 to 81 months).

Conclusions:

Our modified standard TES was demonstrated to be a safe and effective surgical technique for solitary thoracolumbar SM.

Total Knee Arthroplasty for Neglected Habitual Dislocation of Patella with Knee Osteoarthritis
Authors: Chouhan Devendra Kumar , Thami Tarkik , Dadra Ankit
Published: September 2024

Habitual dislocation of patella is characterized by spontaneous dislocation of the patella out of the patellofemoral joint, leading to altered patellofemoral kinematics and possibly early onset of arthrosis.

Case:

We performed total knee arthroplasty (TKA) on a 62-year-old male patient who presented with symptomatic knee osteoarthritis resulting from habitual dislocation of the patella. The patient had a painless unassisted gait with stable patella and 5 to 95° knee range of motion, 23 months after surgery.

Conclusion:

TKA can be an effective treatment option for geriatric patients with habitual patellar instability and concomitant knee osteoarthritis, but may require surgical modifications based on individual pathoanatomy.

Authors: Tyagi Anisha , Sudah Suleiman Y. , Whitelaw Kathryn , Haislup Brett D. , Joshi Tej , Sanchez-Urgelles Pablo , Sanchez-Sotelo Joaquin , Menendez Mariano E.
Published: September 2024

Introduction:

International medical graduates (IMGs) continue to play an important role in the US health care system, but little is known about their trends of matching into highly competitive residencies such as orthopedic surgery. The purpose of this study was to analyze temporal trends of IMG applicants matching into US orthopedic residency programs between 2008 and 2024 and compare them with US allopathic (MD) and osteopathic (DO) graduates.

Methods:

Orthopedic residency specific data for years 2008 to 2024 was obtained from the National Resident Match Program and Electronic Residency Application Service. Variables collected included total number of programs, total positions offered, number of applicants (MD, DO, and IMG), positions filled, and fill rate for each group. Trends were examined using simple linear regression modeling.

Results:

The number of orthopedic residency programs increased from 160 (2008) to 218 (2024), with total positions increasing from 636 (2008) to 916 (2024). The IMG fill rate decreased from 2.99% in 2008 to 0.87% in 2024 (p < 0.01 for linear trend; β −0.069). This corresponds to an absolute number decrease of 19 IMGs in 2008 to 8 in 2024. More specifically, the proportion of US IMGs decreased from 0.94% to 0.66%, and the proportion of non-US IMGs decreased from 2.04% to 0.21%. Over the 17-year study period, a total of 105 US IMGs and 110 non-US IMGs matched into orthopedic surgery. The US MD applicant fill rate decreased significantly from 96.5% to 85.0% (p < 0.001; β −0.944). The DO applicant fill rate increased significantly from 0.31% to 13.97% (p < 0.0001; β 0.990).

Conclusion:

The declining rate of IMGs matching into orthopedic residency programs in the United States underscores the growing challenges faced by IMGs in accessing training in this competitive specialty. The notable increase in DO graduates securing orthopedic residency positions likely reflects the integration of a unified accreditation system for MD and DO residency programs established in 2020.

Coastal & Hydraulics Laboratory Warfighter Support Strategy
Authors:   Coastal and Hydraulics Laboratory (U.S.)
Published: September 2024

This strategy is written for the Coastal and Hydraulics Laboratory (CHL) team and our ERDC collaborators. It is a living document to deliver CHL’s Warfighter support mission. It was written to enable a shared understanding amongst ourselves and our collaborators on where we are now, and where we are going. CHL has a long history of successfully supporting the Warfighter. During World War II, engineers conducted experimentation to support and enable the D-Day landing on the beaches of Normandy. Operation Joint Endeavor marked the resurgence of CHL support to the Warfighter where CHL generated information that enabled the Army to successfully cross the Sava River in Bosnia. More recently, CHL has been a key enabler for the Army in the humanitarian relief mission in response to the Israel-Hamas conflict. This forward-looking strategy is designed to build upon both our past and the present to enable CHL’s readiness to support the Army of the future in meeting its mission. Every member of the CHL team plays an important role in helping CHL accomplish its goal of being a world-class workforce that develops and delivers innovative coastal and hydraulics solutions. As the Warfighter mission evolves to meet future challenges, the work of CHL has never been more critical. We look forward to the positive impacts that will be made as we continue to improve and expand our Warfighter support mission to enable the Army’s multi-domain transformation.
Maritime Militias: Disrupting Naval Operations in the Pacific Theater and the Case for Intermediate Force Capabilities in the Maritime Domain
Authors: Dobias Peter
Published: September 2024

China aims to pursue national goals through a combination of political, diplomatic, and information maneuvering. With China’s growing assertiveness against other countries in the Asia-Pacific region, the risk of a military conflict in the region is increasing. Drawing on the ideological importance of militias, during the last 10 years China heavily invested in building its fleet of maritime militias masquerading as fishing vessels. This article argues that in case of a conflict in the Asia-Pacific, these militias could be employed to interfere with the U.S. and allied forces and supply flow within and into the theater and disrupt naval and amphibious operations in the Pacific theater. While there are limited ways of engaging these forces below a lethal threshold, the intermediate force capabilities could provide the allied forces with a broader range of options, while imposing some cost and dilemmas on the adversary, and potentially contribute to the deterring of their use.
Bringing Clarity to Stand-in Forces: How Operational Art and Science Provide the Linkage between Stand-in Forces, Expeditionary Advanced Base Operations, and Reconnaissance/Counterreconnaissance Operations
Authors: Hassett Pat
Published: September 2024

The U.S. Marine Corps’ 2021 Concept for Stand-in Forces (SIF) “describes how forward-postured, steady-state forces operating in contested areas—capable of transitioning rapidly from competition to crisis to conflict and back again—can create a strategic advantage. This concept explains how Marines can operate effectively with allies and partners from within a contested area.”1 Yet confusion pervades because the Marine Corps organized to perform sustained ground combat operations at the expense of core Title X requirements. The new concepts called SIF—expeditionary advanced base operations (EABO), and reconnaissance/counter-reconnaissance operations (RXR)—articulate potential employment options for Joint force commanders to accomplish regional and threat-focused responsibilities. Doctrinal components of operational art provide linkage between SIF, EABO, and RXR. This framework illuminates the links required to operationalize these novel maritime concepts and to succeed in projecting maritime power in support of Joint and coalition forces.

Permanent magnet motors (PMM) have been around for two decades in the electrical submersible pumps (ESP) industry. PMM are shorter-lighter-higher power density in design and offer more than just energy savings with reduced carbon footprint; it is a technology enabler to achieve asset optimization and yet is underutilized. This paper discusses the early reporting on the first company organic PMM safely installed in a Permian Basin unconventional resource well to extract more reservoir production. The benefit to the reader is stronger confidence to apply this green technology in their wells safely and economically.

To achieve sustainable first use of PMM, the ESP design and safety implications required collaboration of disciplines involving teams of Instrumentation & Electrical, Production and Completion engineers, the ESP Center of Excellence, the Technical Center, Health-Safety-Environmental, and a variety of vendors over a 2-year period. Pump design and drawdown scenarios were examined while multiple safety trainings were conducted, including live demonstrations with PPE, proving the safe mitigation of hazardous voltage through proper shunting, grounding, and isolating standard operating procedures. Additionally, multiple safety devices were added (surface and subsurface) to manage the safety aspects of this technology. A final risk assessment was conducted and approved to clear the way for PMM installation.

Compared to the conventional induction motor, the PMM enabled nearly 50% more power downhole for equal fluid density, comparable production and water cut without a change in pump design. Energy savings and carbon footprint reduction is 19%. Since installation, the ESP system has reduced head pressure more than 300 psi and continues to see increased production. Standard operating procedures for PMM were executed successfully and safely without incident using the free hub second source power mitigator.

Four electrical technologies are included in this paper for safety of personnel and the asset as PMM bring the risk of electrical shock due to two sources of power: planned power from the grid and unplanned power from the well; the latter case the PMM is a generator and this risk is mitigated with the use of both completion and production tools such as the free hub. Additionally, the non-intrusive power measurement technology at the surface keeps personnel safe from arc-flash and electrical shock without the use of cumbersome CAT-2 PPE, a health risk in hot climates. A contactor switch at the surface helps to protect life and asset. Lastly, a common mode filter was run for carrier frequencies less than 4000 Hz to reduce or eliminate high frequency induced failures such as bearing fluting.
A Permian Microgrid Case Study - Keys to Successful Implementations
Authors: Martinez A. Dominguez
Published: September 2024

As the oil and gas industry's interest in more electrified solutions continues to grow, the demand for more complex power management systems is on the rise.

While utilizing utility power to energize a wellsite can help lower emissions, the utility's power typically isn't sufficient to meet a wellsite's high-power demands. Additionally, some applications have very aggressive loads which can conflict with utility companies' aims to keep power steady 24/7. Given these dynamics, understanding the different options available when selecting a power source for a wellsite is imperative to maximize the benefit of all available resources without impacting operations.

This paper examines key considerations for successfully erecting a microgrid system in the oilfield that includes a variety of distributed energy resources (DER) such as gensets and energy storage systems interconnected to a power grid, as well as the option of not only importing power from the grid but also exporting power if needed. Approaches to customize a microgrid to fulfill a wellsite's unique requirements will also be highlighted.

A case study of a wellsite in the Permian powered by a microgrid will be shared. This example will explain how the wellsite, which can require up to 25 megawatts (MW) of power, can successfully operate on 10 MW from the utility with 15 MW supplemented by gas-fueled gensets. It will also cover how the power management system allowed the operator to reduce the need for on-site power generation by 40% by replacing that power demand with grid power.

Preparing the industry toward the future may prove to be the most important outcome of the application as Automation in Directional Drilling is the ability to operate a system with minimum human intervention while automating most analytical repetitive tasks. The principal approach for introducing Automation was to bring revolution in age old directional drilling practices. In this project, downhole automation was utilized with surface automation at an operating rig. The paper focuses on analyzing the results achieved, with the aim of evaluating the methodology and solution's effectiveness, performance, and its impact on drilling operations.

An AI powered downhole autonomous directional drilling system was utilized to drill all zones of well plan, autonomously with minimum interruption from surface. The downhole automation system uses a goal-based approach to handle changes suggested from surface. An automation system that is integrated into the rig control system was also deployed to control the top-drive, drawworks, mud pumps, auto-driller, and downhole tools, to autonomously execute drilling activities.

It focuses on two salient points, the first will be the downhole automation technology and second will be the automation system assisting rig in Drill a stand workflow. There were multiple parties involved in the execution and to make it work, every party must come on same platform for workflows to communicate with each other.

Automation surpassed all the targets set before starting the project. Client believed in the system as it showed how digitization can help to enhance operational efficiency while making the process safer and smoother.
Transforming Pneumatic Methane Emissions Mitigation While Leveraging IRA Energy Credit

Published: September 2024

Natural gas-driven pneumatic controllers used in onshore oil and gas operations account for approximately 43% of all production-related methane emissions in the U.S., primarily due to their deployment in remote areas without access to electric grids. These controllers, essential for process flow and overpressure prevention, have historically lacked technological advancements and commercial solutions for methane emission reduction due to their widespread and remote distribution, the absence of readily available power sources, and the critical impact on operational integrity. The EPA's NSPS OOOO(b) and OOOO(c) regulations, effective as of May 2024, impose strict standards on methane and VOC emissions from pneumatic devices and pumps. The regulations require new and modified pneumatic controllers to achieve zero emissions, with specific guidelines for existing sources, emphasizing monitoring, recordkeeping, and advanced leak detection technologies. These regulations reflect a significant shift towards mitigating the environmental impact of methane emissions from these devices.

Current technologies for emission reduction, including compressed instrument air, electrically powered pneumatic devices, vapor recovery units, and liquified nitrogen, often fall short due to high costs, efficiency losses, and reliance on environmentally harmful energy sources. Renewable energy solutions, though promising, face economic and efficiency barriers, particularly in remote locations. To address the gaps, Blue Mountain Operations developed a new generation of solar-powered instrument air compressors and pumps leveraging high-efficiency Permanent Magnet Synchronous AC (PMAC) motors and VFD controller. This system achieves high electromechanical efficiency and reliability, significantly reducing methane emissions and operational costs while ensuring robust performance in remote settings.

The Inflation Reduction Act (IRA) of 2022 enhanced the Federal Investment Tax Credit (ITC), providing substantial financial incentives for renewable energy projects. In 2023, an oil and gas operator in the Uintah Basin implemented the above-mentioned solar solutions replacing 905 methane-emitting pneumatic pumps in a USD 10.5 million project. This transition qualified for the full 30% ITC and an additional 10% bonus, generated USD 2.8 million in tax credits and demonstrated a viable path for the oil and gas industry to achieve substantial financial and environmental benefits.

Two case studies presented in the paper illustrate the deployment and performance of the PMAC compressor solutions in the Permian and Uintah Basins, demonstrating significant methane emission reductions, cost savings, and enhanced operational efficiency. These projects, supported by financial incentives such as the Federal Investment Tax Credit (ITC) and the Inflation Reduction Act, highlight the economic and environmental benefits of transitioning to sustainable technologies in the oil and gas industry.

The managed pressure cementing technique is new in relative terms to the past 100 years of industry cementing experience (e.g., circa 2008 with first publication). The technique is becoming more prevalent to overcome challenging well integrity requirements which should help the industry achieve zonal isolation for applications previously deemed too difficult to isolate with cement. A literature review of managed pressure cementing (e.g., MPC) success documented in the public domain shows, at the time of the manuscript preparation, the subject case history is the deepest, hottest, and heaviest application. The same literature review identifies several case histories deeper, not hotter or heavier as well as heavier not deeper or hotter. The manuscript shares the challenges faced and success factors to overcome the deployment risks helping to isolate a challenging openhole section using managed pressure cementing.
