Intelligent sensing technology inspired by cell electrophoresis: Dielectric polarization sensor for monitoring the electrical equipment status of IoT nodes

The rapid development of the Internet of Things (IoT) era has led to the emergence of various types of information sensing devices. The operation and maintenance of IoT devices require a large-scale use of sensors at the expense of high energy consumption. In this work, we develop a self-powered voltage monitoring sensor (VSM-S) based on the principle of dielectric polarization, which is inspired by the cell electrophoresis phenomenon. This sensor imitates the structure of biological cells and takes advantage of the easier polarization characteristics of liquid medium with high dielectric constant in an external electric field. It collects electric field energy to achieve self-powering function and can monitor the position and status of the electric field source in real-time through output signals. Experiments show that the designed VSM-S has the characteristics of fast response (10−9-10−15 s), high sensitivity (0.3 nA/V), and wide application range. Furthermore, its integration with monitoring systems enables applications in smart industries, smart homes, and smart grids. This work has considerable development prospects in the fields of wearable sensors and the IoTs.

Differing Approaches to Pain Management for Intrauterine Device Insertion and Maintenance: A Scoping Review.

Intrauterine devices (IUDs) are considered a reliable contraceptive option for women,but they can come with side effects. There is a disconnect in standard guidelines for IUD insertion within and without the U.S. The objective of this review was to address a gap in the literature regarding official procedures for pain management during IUD implantation.This scoping review was initiated using keywords to extract relevant articles from multiple databases: U.S. National Library of Medicine National Institutes of Health (PubMed), MEDLINE (Ovid), and Excerpta Medica dataBASE (EMBASE, Ovid). Initially, 457 articles were identified and after a rigorous screening and selection process, 37 articles were chosen to be further assessed to ascertain if they met the study's inclusion criteria. Those 37 articles were further evaluated fully to check for relevancy. From that process, 19 articles were chosen for the review, and all passed quality assessment evaluations using the JB Appraisal Tools. To best address the research question, the data from the 19 articles were divided into three categories: 1) circumstantial factors, 2) non-pharmacological methods, and 3) pharmacological methods. Circumstantially, women with previous vaginal deliveries experienced the lowest pain during the procedure, and nulligravid (never pregnant) women experienced the most pain. Lower pain scores were reported by lactating women compared to non-lactating. Black women experienced the most anticipated pain compared to other races. Regarding non-pharmacological methods, different insertion techniques, tools, and the use of a cold compress were found to not affect the level of pain during IUD insertion. Lastly, it was shown that pharmacological methods such as lidocaine gel, lidocaine paracervical block, and lidocaine combined with either diclofenac or prilocaine decreased pain scores at different time stamps of the procedure. Also, oral ketorolac and a vaginal combination of misoprostol and dinoprostone helped reduce pain.Findings from this scoping review revealed a lack of uniformity across practices when performing IUD insertions, possibly due to differences in procedures across circumstantial factors, non-pharmacological methods, and pharmacological methods. More research is needed to investigate the intricacies of pain with IUD insertion. Moving forward, especially following a potential increase in the use of IUDs after the reversal of Roe v. Wade, establishing this gap may lead to a more refined standardized protocol to mitigate pain with IUD insertions.

NURSING CARE OF AN ADULT PATIENT UNDERGOING VENO-VENOUS EXTRA CORPOREAL MEMBRANE OXYGENATION (VV ECMO)

In today's dynamic medical environment, evolving technologies and advanced life-saving therapies pose new challenges to nursing care. One of the pioneering achievements in this field is veno-venous ECMO (extracorporeal membrane oxygenation) therapy, which plays a key role in the treatment of adult patients with severe respiratory failure. ECMO, also known as artificial respiratory support, is a revolutionary step towards more effective care for critically ill patients. This article is devoted to a deeper understanding of the role of nurses in the care of an adult patient undergoing venovenous ECMO therapy. Venovenous ECMO therapy is a procedure in which a patient's blood is pumped outside the body, where it is oxygenated, and then reintroduced into the circulation. For adult patients with advanced respiratory failure who do not achieve effective improvement with traditional treatment methods, ECMO often becomes the last resort. However, the complex nature of this therapy requires commitment and expertise from nurses to provide effective patient care. One of the main challenges that venovenous ECMO therapy poses to nurses is monitoring the patient's precise physiological parameters. Strict control of blood pressure, oxygen levels and organ perfusion becomes crucial to the success of therapy. Nurses therefore act as guardians of physiological stability, constantly reacting to possible instabilities and adjusting the parameters of the device under control. It is also worth emphasizing that nursing care for a patient undergoing venovenous ECMO therapy is not limited only to technical aspects. The comprehensiveness of this type of treatment is also associated with concern for the patient's psychosocial aspects. Long-term connection to an ECMO device can cause emotional and mental stress in the patient, which makes the support of nurses in the field of psychological care extremely important. Nurses act as both medical professionals and empathetic companions in difficult times, which translates into the overall success of therapy. The article will also focus on nurses' protocols for dealing with a patient undergoing venovenous ECMO therapy. From an excellent understanding of device maintenance to effective communication with the entire healthcare team, nurses play a key role in ensuring safe and effective therapy. As technology advances and life therapies become more advanced, nurses' skills are continually improved to meet the demands of modern medical care.

Investigation into the Environmental Sustainability Actions Adapted by Small and Medium Enterprises of the Accommodation and Tour Operator Sectors of Sri Lanka

Tourism is a key driver of development for many countries, including Sri Lanka. In 2018, it generated USD 4.38 million in foreign exchange, contributed by 4.9 percent to the GDP, and generated over 380,000 direct and indirect employment opportunities. The contribution of Small and Medium Enterprises (SMEs) to this industry prevents economic leakages and increases the multiplier effect. The tourism industry also can destroy the very environment it depends on for sustenance, through heavy emissions from energy use and waste production. Research has highlighted the importance of the quality of the environment as a pull factor for destination profitability in the long run. The tourism transport-related emissions for Sri Lanka are high, the accommodation sector's GHG emissions at 3 percent is more than the global average of 1%, indicating major areas for improvement. With the accommodation sector's energy consumption predicted to surpass that of the industrial sector, the attention given to sustainable tourism practices by the SMEs that make up the industry must be investigated. In that context, this research aims to investigate the energy-saving and waste-reduction practices towards emission reduction, adopted by the Tour Operator (TO) and Accommodation Provider (AP) SMEs in the tourism industry of Sri Lanka. To do so, a qualitative methodology was adopted with a narrative inquiry over a virtual platform with 06 TOs and 17 APs identified through convenience sampling, and data analysis performed through thematic content analysis technique. Notable results for AP revealed that 12 APs consume electricity off the grid, with solar energy utilization still being limited to obtaining hot water for guest bathrooms for 5 APs, due to the high initial cost involved, and lack of adequate technical know-how in solar battery maintenance (3Aps in Tissamaharama). Poor government support towards renewable energy discouraged 17 APs from adopting the same. Energy use for TO is minimized through the use of hybrid along with conventional fossil-fuel-powered vehicles for tours. Single-use plastic items reintroduced during the COVID-19 pandemic for AP are gradually being replaced by reusable glass bottles, wooden/ metal cutlery, and paper/metal straws. All AP practice waste segregation, and the 3R concept (reduce, reuse, recycle). 4 TOs provide reusable metal bottles that are refilled during the tour using larger water cans and a handheld pump. As the sustainable practices of TO are currently optional, it is recommended to include sustainability criteria into registration process with the SLTDA. For AP it is recommended for the government to play a more active facilitating role in the renewable energy sector and to ensure the skills requirement for device maintenance is promptly met.

Algorithm for ranking applications in QS with priorities in the agro-industrial sector

The study delves into the queuing process for warranty or post- warranty service requests in companies specializing in repairing electronic devices within the agro-industrial sector. The research also investigates the environmental implications of such operations and the environmental challenges related to servicing electronic devices in agricultural production. To streamline maintenance operations and cut costs, a logistic allocation approach for requests is proposed based on queuing systems theory principles. By analyzing workshop operations, a repair work performance scheme is developed, aligning with the specifics of agricultural production and environmental considerations in device maintenance. This has helped outline the primary requirements for the information system, creating diagrams that detail the sequence of processes for order addition, diagnostics, repair, spare parts ordering, and waste disposal. Using terminology from mass service systems, the workshop process is described, and an algorithm for preliminary time parameter calculations has been formulated to predict service completion dates. This methodology not only enables timely updates for customers regarding service completion times and the optimization of order routing through various channels, but it also contributes to addressing the adverse environmental impacts, a critical aspect in the organization of activities within the agricultural sector.

The Circular Digital Cockpit: Towards an actionable framework for life cycle circularity assessment and decision

Digital solutions such as IoT, machine learning, big data, and simulation platforms are increasingly integrated into industrial practices but are not fully leveraged for enhancing circularity in the value chain. To address this, the Circular Digital Cockpit (CDC) framework is proposed to aid manufacturers and public authorities in transitioning towards circularity. The CDC is structured to analyze and improve organizational activities, incorporating Data Science, Digital Enterprise Architecture, and Circular Economy Strategies. It comprises two main parts. The first, "Measure, Understand, Prioritize", focuses on transforming lifecycle data into circularity indicators suitable for various organizational roles, like product and process managers. This helps in prioritizing improvement objectives both individually and organization-wide. The second part, “Act – Imagine, Simulate, Decide, Deploy –, Monitor”, guides each actor in developing and implementing actions aimed at circularity and sustainability goals. This involves assembling a global action plan and employing the Theory of Change methodology to assess and refine these actions based on their impact on circularity and sustainability. The CDC's adaptability and potential in enhancing circular practices across various industries and territorial levels are tested in diverse scenarios, including the remanufacturing of heavy vehicles, the maintenance of medical devices, and the management of bio-waste and construction waste.

A two-terminal fault location method for gas switch prefire in linear transformer driver.

Large-scale linear transformer drivers (LTDs) are composed of numerous high-power gas switches, and switch prefire is a frequent operational fault. To detect and locate the faulty switch accurately and efficiently, a two-terminal location method is proposed. A B-dot sensor is integrated on the gas switch's shell to collect the discharging signal. All the B-dot sensors are connected in parallel through cables of equal length. The fault position can be determined by the time delay of the signals at the two terminals. A diode is inserted between the B-dot sensor's coil and the cable core to ensure low-loss transmission of the signal. Two methods are applied in fault location, including time-of-arrival (TOA) and time reversal (TR). For the TOA method, an energy criterion and a phase criterion are applied and compared. The accuracy of the energy criterion is greatly influenced by the signal-to-noise ratio, while the phase criterion requires a reasonable estimate of the actual delay to account for the impact of phase periodicity. The TR method based on a precise simulation model is established, which demonstrates high precision in location. The TR method has been tested and validated on a single stage LTD module. Moreover, the location method for double switches prefire is discussed theoretically. The method proposed in this paper will be helpful to improve the efficiency of the commissioning, operation, and maintenance of the large-scale LTD devices.

Association between the home-to-healthcare center distance and hearing aid abandonment among older adults.

Access to audiology services for older adults residing in sparsely populated regions is often limited compared to those in central urban areas. The geographic accessibility to follow-up care, particularly the influence of distance, may contribute to an increased risk of hearing aid abandonment. To assess the association between the home-to-healthcare-calibration-center distance and hearing aid abandonment among older adults fitted in the Chilean public health system. 455 patients who received hearing aids from two public hospitals in two regions were considered. Univariate and multivariate Poisson regression models with robust variance estimation were used to analyze the association between the geographical distance and hearing aid abandonment, accounting for confounding effects. Approximately 18% of the sample abandoned the hearing aid, and around 50% reported using the hearing aid every day. A twofold increase in distance between home and the hearing center yielded a 35% (RR = 1.35; 95% CI: 1.04-1.74; p = 0.022) increased risk of hearing aid abandonment. Also, those in the second quintile had a 2.17 times the risk of abandoning the hearing aid compared to the first quintile (up to 2.3 km). Under the assumption that patients reside within the first quintile of distance, a potential reduction of 45% in the incidence of hearing aid abandonment would be observed. The observed risk remained consistent across different statistical models to assess sensitivity. A higher distance between the residence and the healthcare center increases hearing aid abandonment risk. The association may be explained by barriers in purchasing supplies required to maintain the device (batteries, cleaning elements, potential repairs, or maintenance).

Joint Design of Long-Term Base Station Activation and Short-Term Beamforming for Green Wireless Networks

Base station (BS) activation is a widely-used approach to alleviate the system power cost for device maintenance. However, frequently switching on/off BSs may also introduce extra power and signaling costs, which motivates us to limit the BS switching frequency when performing BS activation. To address this, we study a problem of joint long-term BS activation and short-term beamforming (J-LTBA-STBF) in a network where multiple multi-antenna BSs cooperatively serve multiple single-antenna users. LTBA means that each BS’s active/inactive switching frequency is properly controlled to yield relatively stable BS-user association and limited switching power, while STBF lies in that due to the low cost of refreshing beamformers, the transmit beamformers are allowed to be updated frequently to maximally lower the transmit power. Following the idea, two efficient algorithms are designed, according to the data amount they request to start running, to optimize the active BSs and the BS transmit beamformers in multiple adjacent time slices. Consequently, the transmit, maintenance and switching powers can be well balanced to facilitate power-efficient communications. Numerical results validate the efficacies of the algorithms.

Study on Measurement of Liquid Viscosity Coefficient

Based on the traditional falling ball method, the U-tube design is more suitable for measuring transparent or translucent liquids with a large viscosity coefficient. An electromagnetic relay is placed at the upper end of one side of the tube to ensure that the ball falls vertically through the axis of the tube. The other side is sealed with water to prevent the pollution of the liquid to be measured and improve the measurement accuracy. At the same time, it solves the problem of oil leakage in the existing device for a long time, which is convenient for device maintenance and cleaning.

Protecting small and sick newborn care in the COVID-19 pandemic: multi-stakeholder qualitative data from four African countries with NEST360

BackgroundHealth system shocks are increasing. The COVID-19 pandemic resulted in global disruptions to health systems, including maternal and newborn healthcare seeking and provision. Yet evidence on mitigation strategies to protect newborn service delivery is limited. We sought to understand what mitigation strategies were employed to protect small and sick newborn care (SSNC) across 65 facilities Kenya, Malawi, Nigeria and Tanzania, implementing with the NEST360 Alliance, and if any could be maintained post-pandemic.MethodsWe used qualitative methods (in-depth interviews n=132, focus group discussions n=15) with purposively sampled neonatal health systems actors in Kenya, Malawi, Nigeria and Tanzania. Data were collected from September 2021 - August 2022. Topic guides were co-developed with key stakeholders and used to gain a detailed understanding of approaches to protect SSNC during the COVID-19 pandemic. Questions explored policy development, collaboration and investments, organisation of care, human resources, and technology and device innovations. Interviews were conducted by experienced qualitative researchers and data were collected until saturation was reached. Interviews were digitally recorded and transcribed verbatim. A common coding framework was developed, and data were coded via NVivo and analysed using a thematic framework approach.FindingsWe identified two pathways via which SSNC was strengthened. The first pathway, COVID-19 specific responses with secondary benefit to SSNC included: rapid policy development and adaptation, new and collaborative funding partnerships, improved oxygen systems, strengthened infection prevention and control practices. The second pathway, health system mitigation strategies during the pandemic, included: enhanced information systems, human resource adaptations, service delivery innovations, e.g., telemedicine, community engagement and more emphasis on planned preventive maintenance of devices. Chronic system weaknesses were also identified that limited the sustainability and institutionalisation of actions to protect SSNC.ConclusionInnovations to protect SSNC in response to the COVID-19 pandemic should be maintained to support resilience and high-quality routine SSNC delivery. In particular, allocation of resources to sustain high quality and resilient care practices and address remaining gaps for SSNC is critical.

Poned-Based Public Service Innovation in Efforts to Service Pregnant Women at the Wonoasih Health Center, Probolinggo City

This research was about PONED-based public services in efforts to service pregnant women at the Wonoasih Health Center, Probolinggo City. The background of this research was the insufficient examination of pregnant women at the Wonoasih Health Center, Probolinggo City. So that the innovation developed in service delivery was through PONED services. The research method used was descriptive qualitative method. The results of this study were that the Wonoasih Health Center provides specialized PONED services to deal with cases of obstetric emergencies and neonatal procedures that occur during pregnancy, childbirth, and the postpartum period, and are potentially dangerous for the mother and baby. One of them was outlined in the "Mom Love Movement" program to increase the survival rate of pregnant women and reduce the percentage of deaths of pregnant women due to childbirth, and baby safety. Obstacles faced in the development of PONED services were inadequate operational funds, socialization that was not optimal, poor maintenance of medical devices, low quality of inpatient rooms, and the geographic location of the Wonoasih Health Center.

Reuse and Reprocessing of Endoscopic Instruments: For

Reusable endoscopes appear to be most environmentally sustainable when the carbon footprint of routine device maintenance is optimized. Single-use endoscopes may offer cost-savings in clinical settings that accelerate device damage, such as prolonged procedure time or complex patient anatomy. For many urology practices, a hybrid approach that integrates single-use and reusable devices may be most economically sensible and environmentally sound.

Optimization of the Flashing Processes in Mineral Metallurgy Based on CFD Simulations

In mineral metallurgy, the flashing unit is key to returning the slurry to atmospheric conditions. Its primary function is to achieve pressure letdown, and during the process, shock waves are generated to maximize energy dissipation. Investigating the location and expansion of shock waves is the focal point of this study due to their importance in flashing unit design. A CFD model coupled with a homogeneous relaxation model (HRM) was used to simulate the flashing process of mineral slurry. The flow behavior, including velocity, pressure, and the shape and location of the shock waves, were obtained using simulation under different unit design and operating parameters. These results would provide valuable insights into the design of flashing units and guidance for the safe operation and maintenance of devices.

Foundation for implementing a comprehensive vascular access excellence initiative organization-wide to improve vascular access device insertion and standardize care: best practice for an acute care hospital.

In 2016, a 263-bed public district hospital in California trialed a peripheral intravenous catheter (PIVC) inserted using ultrasound, with the potential to increase first attempt success in difficult intravenous access (DIVA) patients. This led to the implementation of a hospital-wide initiative to improve nursing vascular access skills and expedite vascular access device (VAD) placement. To trial a PIVC and ultrasound-guided (USG) insertion, a training program was developed and led to a doctoral Capstone project piloting an evidence-based nurse-driven protocol for the identification of DIVA patients. A Vascular Access Committee was established to achieve vascular access excellence throughout the hospital by increasing the number of nurses with advanced skills in VAD placement and by developing a central venous access device (CVAD) insertion and maintenance bundle to decrease the incidence of central line-associated bloodstream infections (CLABSI). With ongoing support of nursing leadership and achievement of ANCC Magnet Recognition® in 2021, the hospital developed a comprehensive initiative to provide patients with a consistent level of nursing expertise for VAD placement across all shifts. Requests for USGPIVCs increased throughout the hospital, DIVA patients themselves requested ultrasound guidance be used for PIVC insertions, and there were fewer requests for Emergency Department (ED) physicians to insert CVADs. From the related Doctor of Nursing Practice (DNP) Capstone project, there were higher first-attempt cannulation successes, longer PIVC dwell times, and a reduction in devices and supplies utilized. The CVAD bundles resulted in the number of central line-associated bloodstream infections decreasing from four in 2019 to one in 2020. Since the initiative's inception, a total of 92 nurses completed the USGPIVC insertion training, and patient access to advanced-skilled clinicians is now available around the clock. This manuscript discusses the initiative implemented to standardize patient care through a collaborative multidisciplinary approach and has potential generalizability to other acute care hospitals to reduce associated healthcare costs and to prevent poor patient outcomes by expediting the arrival of a vascular access nurse for DIVA patients. The vascular access excellence initiative implemented provided an effective strategy to enhance the skills and confidence of nurses in VAD placement and improved efficiency in processes to expedite the arrival of an advanced skilled nurse to place VADs on DIVA. Targeted educational initiatives improved patient outcomes by reducing catheter-related bloodstream infections.

Subject and Family Perspectives from the Central Thalamic Deep Brain Stimulation Trial for Traumatic Brain Injury: Part II.

This is the second paper in a two-part series describing subject and family perspectives from the CENTURY-S (CENtral Thalamic Deep Brain Stimulation for the Treatment of Traumatic Brain InjURY-Safety) first-in-human invasive neurological device trial to achieve cognitive restoration in moderate to severe traumatic brain injury (msTBI). To participate, subjects were independently assessed to formally establish decision-making capacity to provide voluntary informed consent. Here, we report on post-operative interviews conducted after a successful trial of thalamic stimulation. All five msTBI subjects met a pre-selected primary endpoint of at least a 10% improvement in completion time on Trail-Making-Test Part B, a marker of executive function. We describe narrative responses of subjects and family members, refracted against that success. Interviews following surgery and the stimulation trial revealed the challenge of adaptation to improvements in cognitive function and emotional regulation as well as altered (and restored) relationships and family dynamics. These improvements exposed barriers to social reintegration made relevant by recoveries once thought inconceivable. The study's success sparked concerns about post-trial access to implanted devices, financing of device maintenance, battery replacement, and on-going care. Most subjects and families identified the need for supportive counseling to adapt to the new trajectory of their lives.

Demographic, medical, and financial statistics from the Jaffna Jaipur Centre for Disability Rehabilitation (JJCDR) database, 1987-2018: a prosthetics, orthotics, and mobility clinic in northern Sri Lanka

Background When dealing in global health, it is crucial to have a comprehensive understanding of community demographics and needs. From 1983-2009, a 26-year ethnic civil conflict devastated Sri Lanka, disproportionately affecting people living in the north and creating a large amputee population. Here, we use routinely collected prosthetic and orthotic data to investigate the composition of the amputee community in northern Sri Lanka. Methods The Jaffna Jaipur Centre for Disability Rehabilitation (JJCDR) was established in 1987 and has been the only centre consistently providing prosthetic, orthotic, and non-orthopaedic services in northern Sri Lanka spanning during and after the civil war. In 2004, with the help of the charity Motivation, they established an electronic patient database, which records and maintains information on the JJCDR’s patients. An anonymized copy of the JJCDR database was obtained in November 2018. Summative statistics and temporal trends in patient data were investigated. Results 3,665 unique patients registered with the JJCDR from 1986-2018 (2,605 male, 1,060 female). Individuals ranged from 0-90 years old, with a mean/median age of 34.76/32 years old. Key findings include: (i) 93.0% patients with amputation site recorded were lower limb amputees, with 74.3% being transtibial amputees; (ii) The majority of patients with cause of amputation recorded had war-related amputations (61.2%); (iii) diabetes was the highest cause for non-war-related amputations (18.3%); (iv) war-related amputations have ceased, while diabetic amputations are on the rise; and (v) peak recorded financial costs due to prosthetic and orthotic (P&O) creation/maintenance occurred in 2013, 4 years after the war ended. Conclusions These analyses provide crucial insight into the P&O population in northern Sri Lanka, including distribution and frequency for causes/sites of amputations, temporal patterns in causes of amputations, and costs to a P&O centre due to device creation and maintenance. This database and analysis provide invaluable insight into the P&O cohort in northern Sri Lanka, and a unique insight into the P&O needs of a post-conflict LMIC from the perspective of a P&O centre.
