Adaptive Complex Systems Applied in Electrical Submersible Pumps Control
Authors: Castañeda J G. E. , Ferreira J. V. 
Published: March 2023

SummaryThe oil and gas industry uses very expensive electrical submersible pumps (ESPs) to lift oil to the surface. It is common for the ESP to operate with a biphasic gas-liquid flow. However, large amounts of gas inside the pump generate instabilities, such as surges and gas locks. If operated for a long time under such instabilities, the performance of the ESP can decrease significantly, causing premature deterioration, which can lead to heavy losses and even a complete stoppage of production. To reduce the occurrence of this unstable operation, the research presented here proposes an adaptive controller based on the monitoring of the biphase condition. A nonlinear ESP model represents the pump behavior for a variable percentage of the two-phase flow, used by the controller learning complex adaptive technique, which is based on a genetic algorithm to generate a set of rules to keep the ESP in safe operating conditions. At the beginning of the training, the adaptive complex system generated erratic behavior; however, over time, it came to represent more precise rules, bringing performance to stable conditions. Furthermore, if the ESP eventually reaches a harmful condition, the adaptive controller takes action to return it to a safe condition. The result of the simulated tests shows that the complex adaptive controller can acquire enough knowledge after training to keep an ESP working in stable conditions, increasing the life of the production equipment and avoiding sudden stops during oil lifting.

Published: March 2023

Abstract
Pertamina is the only one state oil enterprise in the country has a strategic position in the national development, mainly in terms of foreign exchange and domestic energy supply.
Hence human factor in the company productivity is very important. Workday loss by sickness in the last 4 years was 2.00 %o up to 3.00 %o and 0.88 days up to 1.12 days loss per worker annually Workday loss by sickness was 96.86 %up to 98.12 %&gt; of total workday loss and the rest by work injuries.
These relative low sickness absence figures achieved by multidisciplinary efforts in the company mainly by health department. All sickness absence certificate even for one day off should be signed by company medical doctor. Health department conduct comprehensive health care including occupational health programme. Health & safety issues solved by multidisiplinary approach. Beside health department also organize employee assistance programme (counseling) mainly for healthy life style and psychosocial problems.
The low workday loss is one of the basic important factors to support discipline and human productivity mainly since mostly oil reserve discoveries located in the remote areas inland as well as offshore.

Abstract
Nowadays, with the gradual development of intelligent transportation and the widespread popularity of private cars, the Internet of Vehicles (IoV) technology is gradually coming to maturity. However, the development of smart cars has been accompanied by a concomitant increase in the amount of media as well as video games in the vehicle, and an explosion in the demand for computational resources. Since smart cars have limited computing resources of their own, they cannot store a large number of pending tasks in their own queues, so they cannot compute the large number of requests generated by the vehicles themselves. The lack of computing resources can be better solved with the help of edge servers, and the distribution of edge servers close to the user side of the road can also effectively achieve real-time for resource requests, but the high energy consumption generated during processing is also a challenge we must face. To address this challenge, a joint task offloading approach based on mobile edge computing and fog computing (EFTO) proposed in this paper. Technically, the location of the processing task is first obtained by getting the route of the computing task, thus finding the complete routing information of the task from the initial location to the target location. Then, a genetic algorithm is used to implement a multi-objective optimization problem to reduce the time and energy consumption during offloading and processing. Finally, the effectiveness of EFTO is demonstrated through comparative experiments, which shows a reduction in time consumption and an optimization of energy consumption compared to other offloading methods.

Abstract
Background: Childhood dementias are a group of over 70 rare and ultra-rare paediatric conditions clinically characterised by enduring global decline in central nervous system function, associated with a progressive loss of developmentally acquired skills, quality of life and shortened life expectancy. Traditional research, service development and advocacy efforts have been fragmented due to a focus on individual disorders, or groups classified by specific mechanisms or molecular pathogenesis. There are significant knowledge and clinician skill gaps regarding the shared psychosocial impacts of childhood dementia conditions. This systematic review integrates the existing international evidence of the collective psychosocial experiences of parents of children living with dementia.
Methods: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We systematically searched four databases to identify original, peer-reviewed research reporting on the psychosocial impacts of childhood dementia, from the parent perspective. We synthesised the data into three thematic categories: parents’ healthcare experiences, psychosocial impacts, and information and support needs.
Results: Nineteen articles met review criteria, representing 1856 parents. Parents highlighted extensive difficulties connecting with an engaged clinical team and navigating their child’s rare, life-limiting, and progressive condition. Psychosocial challenges were manifold and encompassed economic, social, and psychological implications. Access to coordinated healthcare and community-based psychosocial supports was associated with improved parent coping, psychological resilience and reduced psychological isolation. Analysis identified a critical need to prioritize access to integrated family-centred psychosocial supports throughout distinct stages of their child’s condition trajectory.
Conclusion: This review will encourage and guide the development of evidence-based and integrated psychosocial resourcesto optimise quality-of-life outcomes for of children with dementia and their families.
Soil Loss and Sedimentation Rates in a Sub-Catchment of the Yellow River Basin in China

Published: March 2023

Abstract

Soil loss by water erosion is one of the main threats to soil health and food production in intensively used agricultural areas. To assess its significance to the overall sediment production we applied the Water and Tillage Erosion Model/Sediment Delivery model (WaTEM/SEDEM) to the Luoyugou catchment, a sub-catchment of the Yellow River basin within the Chinese Loess plateau. WaTEM/SEDEM considers rill and inter-rill erosion and deposition rates, resulting in sediment yield rates leaving the catchment. Although terraces were established in the 1990s to reduce soil loss, no further soil erosion modeling has been published for this area. Applying 1000 Monte Carlo simulations of the WaTEM/SEDEM, modeled average soil loss by rill and inter-rill erosion for 2020 was 12.4 ± 11.8 t ha-1 yr-1, with sediment yield at the outlet of 52949 ± 11215 t yr-1. Terracing reduced erosion rates, while land cover changes, mainly conversion of forests and grassland partly counteracted the mitigation (combined effect: 50% reduction). Modeled sediment loads by rill and inter-rill erosion account for 17.1% of the total long-term sediment production recorded by flow discharge measurements. Other processes not considered by the model like landslides, gully erosion, riverbank erosion, and sediment production by construction seem to dominate overall sediment yield. Considering years with baseline sediment production only, measured and modeled sediment yield compared well, indicating that the latter processes contribute mainly during extreme events.

Published: March 2023

Abstract
The attributes of a memristor such as non-volatile, simple structure, no leakage current, and fast switching speed have unfolded enormous opportunities for various analog and digital applications. It is imperative to develop an accurate physical model of the memristor in order to design digital applications. The hitherto published memristor modeling approaches do not match with the practical memristor dynamics. A new model is developed by considering Schottky contact at the metal-insulator-metal (MIM) interfaces. In this research work, a novel memristor is also fabricated to validate the proposed model. A bead polymer based on methyl methacrylate and n-butyl methacrylate (MMBM) is firstly used to explore the resistive switching properties of the device. A cost-effective screen printing technique is first demonstrated to deposit the resistive switching layer for the fabrication of the memristor. The resistive switching behavior is observed in the sandwiched layer with a silver (Ag) as a top electrode and copper (Cu) as a bottom electrode. Surface morphology and electrical characterizations of the fabricated device are carried out by scanning electron microscope and 2 probe resistivity measurement. The results validate the formation of the Schottky barriers at the MIM interfaces of the fabricated device. The proposed model is compared with the device described in this paper having an error of 0.7609 (in terms of the relative root-meansquare error). Moreover, the NOR logic gate is simulated for the circuit simulation of the proposed model. This will pave a new path for the digital design applications based on the memristor.

Published: March 2023

Abstract
Background: IM-ITE is a self-evaluation instrument administered annually to provide residents and program leadership with a measure of the residents' knowledge compared with that of their peers nationwide. Many approaches have been used to improve the IM-ITE scores as a means of achieving a higher first-time board examination pass rate. While these interventions helped improve outcomes in target programs, it remains unclear whether one approach was superior to another and how different program demographics may have played a role in the outcome of the intervention.
Objective: To identify the most effective methods used to improve IM-ITE scores in the literature.
Methods: We searched MEDLINE database on 12/4/2022, using the keywords: “internal medicine” AND “in-training exam” AND “performance”.
Results: A total of 35 articles were examined. Five articles met the inclusion criteria. Three of which were conducted in community-based residency programs. Two were conducted in university-based residency programs. None of these residency programs were new (established in the last 10 years) and all studies were carried out in a single institution. Interventions identified include creating a new curriculum, implementing a multiple choice-testing program, identifying learning styles associated with better IM-ITE performance, and transitioning to an academic half day (AHD) didactics structure.
Conclusion: We identified a myriad of interventions that were successful at improving IM-ITE performance in their target cohorts to variable degrees. Interventions summarized in this review can be utilized by residency programs to improve IM-ITE performance among their residents and provide guidance to their faculty members in the process.
Forecasting Carbon Emissions in Chinese Coastal Cities Based on a Gated Recurrent Unit Model

Published: March 2023

Abstract
Scientific forecasting of carbon emission trends is an important basis for understanding carbon emission levels and is a key reference for achieving dual carbon goals. Carbon emission prediction models based on backpropagation neural networks and multiple linear regression methods have yielded relatively favourable results. Compared with traditional methods, deep learning offers plasticity and effectiveness, and has been verified by application in multiple fields. In this study, a carbon emission forecasting model was built based on the gated recurrent unit model to empirically evaluate data from 16 coastal cities in China from 1997 to 2019. Eight scenarios were established to forecast carbon emissions in Chinese coastal cities from 2020 to 2029, and to investigate the combined effects of the factors driving carbon emissions, including economy size, industrial structure, and public revenue. Our results predict increasing carbon emissions from 2020 to 2029, with substantially slower growth compared with the change in carbon emissions from 1997 to 2019. Furthermore, the eight scenarios show that changes in driving factors, including public revenue, industrial structure, and size of the economy, strongly impact on carbon emissions. The size of the economy has the most significant effect on carbon reduction. Therefore, the marine economic growth model needs to be redesigned and further developed with a view towards carbon emission reduction and low-carbon development.
Family Physicians’ experiences with an innovative, community-based, hybrid model of in-person and virtual care: A mixed-methods study

Published: March 2023

Abstract
Introduction: Rural, remote, and underserved communities have often struggled to provide adequate access to family physicians. To bridge this gap in Renfrew County, a large, rural region in Ontario, Canada, a community-based, hybrid care model was implemented, combining virtual care from family physicians and in-person care from community paramedics. Studies have demonstrated the clinical and cost-effectiveness of this model but its acceptability to providers has not been examined. This study investigates the experiences of participating family physicians.
Methods: A mixed-methods study, combining physician questionnaire response data and qualitative thematic analysis of focus group interview data.
Results: Data was collected from n=17 survey respondents and n=9 participants in two semi-structured focus groups (n=4 and n=5 respectively). Physicians reported high satisfaction, driven by skills development and patient gratitude, and felt empowered to reduce ED visits, care for unattached patients, and address simple medical needs. However, physicians found it difficult to provide continuous care and were sometimes unfamiliar with local healthcare resources.
Discussion: This study found that a hybrid model of in-person and virtual care from family physicians and community paramedics was associated with positive physician experiences in two main areas: clinical impacts, especially avoiding unnecessary ED visits, and physician satisfaction with the service. Potential improvements for this hybrid model were identified, and include better support for patients with complex needs, and more information about local health-system services. Our findings should be of interest to policymakers and administrators seeking to improve access to care through a hybrid model of in-person and virtual care.
Spectrum of diabetes mellitus in patients with Shwachman-Diamond syndrome: case report and review of the literature

Published: March 2023

Abstract
Background.
Shwachman-Diamond syndrome (SDS) is a rare congenital disorder caused by mutations in the SBDS gene and characterized by exocrine pancreatic deficiency, hematologic dysfunction, and skeletal growth failure. Although the hematologic features and characteristics of the somatic disorders commonly associated with SDS are well known, emerging data from case reports and patient registries suggest that SDS may also be associated with an increased risk of diabetes mellitus. However, currently available data on SDS-associated diabetes are limited and do not allow conclusions regarding prevalence and incidence rates, clinical course, and outcomes.
Case presentation
Here we report the case of a 5-year-old girl with SDS who underwent bone marrow transplantation at the age of 3 months and developed autoantibody-positive type 1 diabetes mellitus at the age of 1.8 years. The manifestation and course of diabetes development were mild, complicated by concurrent spontaneous episodes of hypoglycemia even before the onset of antidiabetic treatment. Currently, adequate metabolic control can be achieved by dietary intervention.
Conclusions
Considering that the SBDS protein regulates mitosis and ribosomal biosynthesis and that its suppression may cause immunologic instability and chronic inflammation, this case provides insight into the phenotype of rare Shwachman-Diamond syndrome-associated diabetes mellitus, which may be characterized by significant age-dependent differences in clinical course.

Published: March 2023

Abstract
The present study aimed to test the efficiency of transcervical artificial insemination techniques with cervical immobilization (TCAI-CI) or cervical traction (TCAI-CT), associated or not with the use of oxytocin (OT) as a protocol for cervical dilation, in the brown brocket deer (Subulo gouazoubira). The study was carried out in a crossover design using four adult females in two replicates with an interval of 60 days. Estrus was synchronized with oral melengestrol acetate (MGA) associated with estradiol benzoate and sodium cloprostenol. TCAI techniques were performed from 18 to 24 hours after estrus onset. All females received either an i.v. Apply 50 IU OT (G-OT, n = 4) or 1 mL saline solution (G-Control, n = 4) 20 minutes before the TCAI procedure. The TCAIs were performed using frozen-thawed semen from the same batch. Behavioral estrus was observed in 100% of females, within the two replicates, with a mean time of onset of 44.0 ± 22.0 h after cloprostenol application. The average length of the vagina was 13.0 ± 1.2 cm. It achieved a 50% (4/8) success of cervical transposition with semen deposition in the uterine. Regarding inseminations, most of them (87.5%) were performed using the TCAI-CT technique, and the overall conception rate was 50%. Cervical transposition times (< 1 minute) and TCAI procedures (~ 17 minutes) could be considered satisfactory. Thus, the TCAI-CI and TCAI-CT techniques performance was successful when applied in S. gouazoubira females, regardless of the use of OT as a cervical dilation protocol. This procedure is proposed as a method of choice for artificial insemination with greater applicability in different conservation centers, compared to more advanced reproductive biotechniques, and with a favorable impact on the conservation of deer species.

Abstract
Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic disease for which no effective treatment is available. Transforming growth factor-β (TGF-β) is thought to be involved in the pathogenesis of IC/PBS, and previous studies have suggested that administrations of a TGF-β inhibitor significantly ameliorated IC/PBS in a mouse model. However, the molecular mechanisms underlying the therapeutic effect of a TGF-b inhibitor on IC/PBS has not been comprehensively analyzed. TGF-β has a variety of actions, such as regulation of immune cells and fibrosis. In our study, we induced IC/PBS-like disease in mice by an intravesical administration of hydrogen peroxide (H₂O₂) and examined the effects of three TGF-β inhibitors, Repsox, SB431542, and SB505124, on the urinary functions as well as histological and gene expression profiles in the bladder. TGF-β inhibitor treatment improved urinary function and histological changes in the IC/PBS mouse model, and SB431542 was most effective among the TGF-β inhibitors. In our present study, TGF-β inhibitor treatment improved abnormal enhancement of nociceptive mechanisms, immunity and inflammation, fibrosis, and dysfunction of bladder urothelium. These results show that multiple mechanisms are involved in the improvement of urinary function by TGF-β inhibitor.

Abstract
Objectives: The purpose of this systematic review is to evaluate the safety and efficacy of nafamostat mesilate (NM) for continuous renal replacement therapy in high bleeding risk patients.
Methods: We performed a comprehensive search on PubMed, Embase, CINAHL, Web of Science, the Cochrane Library, and CNIK from inception to May 1, 2022. Two reviewers independently screened, selected, and extracted data.A meta-analysis was conducted using RevMan 5.3 software. The systematic review protocol was registered.
Results: 7 studies with 639 high bleeding risk patients were included for review including 4RCTs and 3 retrospective cohort studies. The anticoagulant in the control group of all included studies was anticoagulation-free. Compared with the baseline data, the activated partial thromboplastin time of the NM group was shortened at the end of observation (MD -12.16, 95% CI -23.70 to -0.62, p= 0.04). NM for CRRTsignificantly extended filter life (MD 9.65, 95% CI 5.60 to 13.71, p< 0.00001)and reduced mortality compared with anticoagulation-free treatment (RR 0.76, 95% CI 0.64 to 0.90, p= 0.002). No significant difference was observed in the incidence of bleeding complications (RR 1.16, 95% CI 0.59 to 2.26, p= 0.67) and total duration of CRRT (MD 12.65, 95% CI -6.79 to 32.09, p= 0.20) between the groups. Subgroup analysis showed the same results except for the mortality outcome.
Conclusions: For patients at high bleeding risk undergoing CRRT, NM is a better anticoagulation option. More multicenter RCTs with large samples are required to validate and compare the effects of NM anticoagulants.
