Jednym ze sposobów skutecznego wspomagania wydobycia ropy naftowej jest zatłaczanie dwutlenku węgla do złoża. Z jednej strony skutkuje to zwiększeniem energii złoża, z drugiej zaś – ze względu na własności zatłaczanego gazu – powoduje efektywne wypieranie ropy naftowej. Dodatkową zaletą takiego rozwiązania jest możliwość wykorzystania złoża, po jego wyeksploatowaniu, do celów składowania CO2. W procesie zatłaczania CO2 napotyka się jednak na szereg problemów związanych zarówno z samym procesem, jak i jego efektami. Jedną z podstawowych trudności jest szybka migracja dwutlenku węgla do odwiertów produkcyjnych, co wymusza konieczność takiej lokalizacji odwiertów zatłaczających, aby z jednej strony zjawisko to zachodziło jak najpóźniej, a z drugiej strony proces zatłaczania był efektywny. Innym problemem jest szczelność struktury zarówno ze względu na nadkład, jak i stabilność geomechaniczną uskoków. Niezależnie od wymienionych problemów konieczna jest również analiza techniczno-ekonomiczna projektu w celu zapewnienia jego rentowności. Celem artykułu jest przeprowadzenie weryfikacji możliwości zastosowania zatłaczania CO2 jako metody wspomaganego wydobycia ropy naftowej na przykładzie rzeczywistego złoża. Pierwszym etapem realizacji (nieprzedstawionym w artykule) była analiza statycznego modelu geologicznego złoża uwzględniająca różne scenariusze rozkładów przestrzennych parametrów istotnych dla potencjału zatłaczania CO2 oraz analiza niepewności modelu wraz z oszacowaniem teoretycznej pojemności sekwestracyjnej struktury. Następnie na bazie zbudowanego modelu geologicznego został skonstruowany oraz skalibrowany model dynamiczny. Na jego podstawie zostały przeprowadzone symulacje złożowe procesu zatłaczania dwutlenku węgla dla wyznaczenia podstawowych charakterystyk pracy złoża oraz określenia ogólnego schematu rozmieszczenia odwiertów zatłaczających CO2.

Practice shows that the temperature around drilling and production wells is of great interest in terms of design choices and preventing the precipitation of heavy fractions (paraffins, resins, asphaltenes). A literature analysis has demonstrated that the temperature of the elements of drilling and production wells can be determined with sufficient reliability using the method of successive changes in the stationary state. To select downhole equipment, both during drilling and operation, it is necessary to determine the temperature values for the wells. The performed calculations indicate that the change in the temperature of hydrocarbons along the wellbore during flow operation is considered in three cases of annulus filling. To refine the temperature calculations, they must be conducted step by step, dividing the length of the lift into specific intervals. Similar temperature calculations are also carried out for injection wells when hot water is injected into the reservoir. In such cases, it is important to maintain the temperature of the injected water above the formation temperature. The temperature of the water injected into the reservoir from the wellhead to the bottom of the well is determined by solving the equations of thermodynamics and heat transfer jointly. Literature analysis shows that, to calculate the temperature of produced or injected water, it is necessary to know the thermophysical properties of well production, reservoir fluids, cement stone, and surrounding rocks. In a particular case, a water-gas-oil mixture moves through a production well, with the concentration of its phases and components changing as it moves upwards to the wellhead. A similar mixture system is also present in the annular space between the pipe strings and within the pores of the rock.

Authors: Butler-O'Hara Meggan , Goldman Mary , Aspenleiter Taylor , Vanini Caitlin , Dadiz Rita
Published: January 2025

Advanced practice providers (APPs) experience limited clinical opportunities to perform neonatal procedures to maintain competency and hospital credentialing, especially high-acuity procedures that are extremely rare but crucial during patient emergencies. Incorporating simulation as part of continuing professional education can help APPs maintain clinical procedural competency and learn new procedural techniques to improve the quality and safety of procedures performed in the clinical setting. In 2013, we successfully developed and implemented an annual didactic and simulation-based neonatal procedural skills program. Since then, our APP group has experienced significant growth, which introduced challenges to sustain a high-quality program that would be valued by participants. These challenges presented the opportunity for a major program redesign addressing education, competency, credentialing, safety, and quality improvement. In this article, we describe the challenges that we uncovered from a comprehensive needs assessment that informed program redesign. We also present evaluation of the redesigned program, which includes learner, patient care, and systems-based outcomes.

Published: January 2025

Respectful maternity care (RMC) is a topic that has received increasing focus among clinicians, researchers, and the public in recent years. While clinicians recognize the importance of respectful care, patients report that they are not consistently receiving it. The Association of Women’s Health, Obstetric and Neonatal Nurses (AWHONN) created the RMC Framework, Evidence-Based Guidelines and Implementation Toolkit to provide nursing teams with the knowledge, tools, and structures they need to promote RMC. For true change to happen, the implementation of respectful care must be translated across the maternity care continuum, including in the NICU. This article shares a health care organization’s journey toward respectful, equitable maternity care for women, neonates, and their families. This article outlines the AWHONN RMC Framework and the leverage of its components to promote RMC for neonates and their families in the NICU. The outcomes of these efforts are also highlighted.

The Seridó UNESCO Global Geopark (SUGG) was approved in 2022. In all, the Geopark has 21 geosites, the main interest of which is geomorphological. Despite the importance of the geomorphological heritage in the SUGG territory, the area had not yet been mapped on a scale suitable for geoconservation actions by the SUGG technical staff and its scientific committee. The present work aims to identify landforms up to the fourth taxon, corresponding to types of relief forms, according to Ross's (1992) methodological proposal for the geomorphological mapping of Brazil. Landform hierarchy was established following the morphological taxon typology proposed by the RadamBrasil Project and described by Ross (1992). The first three taxons correspond to those of Diniz et al. (2017) for the Rio Grande do Norte geomorphological map. However, for this study, the fourth taxon was added. This scale and taxonomic level were considered suitable for geoconservation actions. Maps are also presented at higher taxonomic levels, with less detail, which are more suitable for geoeducation activities with schoolchildren in the SUGG territory.

Authors:   , Custodio Uribe Adrian Eduardo
Published: January 2025

Los estudios sobre la concentración de mercurio en tejido muscular de elasmobranquios son escasos en Perú y necesarios para estimar riesgos a la salud pública. La concentración de mercurio en el tejido muscular del tiburón azul (Prionace glauca) de 40 ejemplares capturados entre mayo del 2019 hasta febrero del 2020, frente al sur de Perú y norte de Chile, y desembarcado en el puerto de Ilo, ha fluctuado entre 0.04 y 0.29 mg.kg-1 de peso húmedo, estando por debajo de los valores encontrados en otros estudios, así como del máximo permisible (1 mg.kg de peso húmedo). La correlación entre la concentración de mercurio y la longitud total estimada fue débil (p=-0.18), mediante análisis de covarianza se detectó un aparente efecto significativo de las estaciones (p=0.021), pero no del sexo (p=0.447). Según los valores del coeficiente de riesgo (THQ) y la ingesta semanal máxima (ISM) de filetes de tiburón azul, no representan peligro alguno para la salud pública. Sin embargo, se plantea extender este estudio hacia diferentes especies de elasmobranquios y zonas de la costa peruana.
Generative artificial intelligence causes displacement for white-collar workers but reduces regional opportunity disparities
Authors: Liu Lun , Hu Jiayin , Wang Anqi , Weng Zongyuan
Published: January 2025

Recent developments of generative artificial intelligence (GenAI) have reignited discussions about technological unemployment, yet empirical evidence remains scarce. Using a comprehensive dataset of over one million online job postings from China spanning 2018 to 2024, this study provides a timely assessment of GenAI’s impact on local and regional labor markets following the surge of GenAI tools in late 2022. Our analysis reveals a nontrivial job displacement effect of GenAI in the short and medium run, disproportionately affecting entry-level, high-wage positions and highly-educated workers. Notably, this displacement effect is more pronounced in larger, more economically developed cities, suggesting a reduction in job opportunity disparities across regions in era of GenAI. We also find that lower labor costs and higher occupation diversity increase the resilience of local labor markets to the disruptive effects of GenAI. These findings offer crucial insights for policymakers to mitigate the adverse consequences of GenAI while harnessing its potential for positive societal transformation.
Crystal Phase Reconstruction of Bi-(N-C)/Bi(OH)3-Bi2O3 for Selective Cleavage of Lignin Cꞵ-O-4 Bond via Fluidized Electrocatalysis
Authors: Xu Junming , Shi Jingjing , Lu Yanju , Long Feng , Chen Zupeng , Jiang Jianchun
Published: January 2025

Developing efficient systems for directional lignin depolymerization via cleaving the aryl ether bonds to produce high-value-added chemicals is intriguing but remains challenging. Herein, we report a crystal phase reconstruction strategy for the synthesis of heterogeneous Bi-(Et3N)0.3 catalyst with rich defect sites and high-valence Bi species, which exhibits promising performance towards the fluidized electrocatalytic hydrogenation (FECH) of lignin-derived 2-phenoxy-1-phenylethanol with full conversion and up to 60.7% yield of phenol formation. Experimental and theoretical results confirm that the high-valence Bi species is beneficial in promoting the rapid activation of the protons, while the rich-defect sites derived from the crystal phase reconstruction between Bi-O and Bi-N-C coordination optimize the adsorption-activation of oxygen-containing intermediates. Moreover, by manipulating the variation of current density, the dissociation efficiency of protons and the enrichment degree of the electron-rich ([PW10VIW2VO40]5−) groups of the phosphotungstic acid (HPW) electrolyte were modulated, enabling the controllable switching of the phenol generation pathway. This study elucidates that the synergy between defect sites and high-valence Bi metals could advance the rational design of efficient electrocatalytic systems for the directional and efficient cleavage of lignin Cꞵ-O-4 bonds for high-value-added chemicals.
Hematological Changes in Total and Differential Count in Pre and Post Hemodialysis of Adult Chronic Kidney Disease Patients
Authors: Ogolla Collince Odiwuor , Karani Lucy W. , Musyoki Stanslaus , Maruti Phidelis
Published: January 2025

Background: Hematologic abnormality, especially anemia, and changes in total and differential blood counts are mostly observed with this condition. Advanced CKD patients undergo hemodialysis as a standard treatment, and consequently, the parameters go along with these patients. Acquiring the relevant changes will help in improving patient management and complications arising from CKD.
Objective: To evaluate the change in total and differential blood counts in adult CKD patients before and after hemodialysis, especially as it concerns levels of hemoglobin, hematocrit, red blood cells, white blood cells, platelets, and differential count (neutrophils, lymphocytes, monocytes, eosinophils).
Methods: A prospective observational study was conducted at Kisii Teaching and Referral Hospital, Kenya, on 120 adult chronic kidney disease patients on hemodialysis. Blood samples were taken before the start of the dialysis session (pre-hemodialysis) and taken within 30 minutes after the dialysis session (post-hemodialysis). Automated hematology analyzer performed all necessary hematological analysis that included total blood count and differential blood count. The data were analyzed using SPSS version 26. Pre- and post-hemodialysis values were compared with t tests for paired samples or Wilcoxon signed-rank tests.
Results: The mean hemoglobin concentration increased significantly from a baseline value of 8.4 ± 1.9 g/dL pre-hemodialysis to a post-hemodialysis concentration of 10.1 ± 2.1 g/dL (p < 0.001). Hematocrit and red blood cell counts also increased considerably (p < 0.01). White blood cell counts dropped significantly from 8.5 ± 3.4 × 10³ cells/μL pre-hemodialysis to 7.3 ± 2.8 × 10³ cells/μL post-hemodialysis (p = 0.004). The platelet count also fell from 270 ± 82 × 10³ cells/μL pre-hemodialysis to 248 ± 75 × 10³ cells/μL post-hemodialysis (p = 0.03). Neutrophil percent decreased while lymphocyte percent increased significantly post-hemodialysis (p = 0.01 and p = 0.02 respectively).
Conclusion: Hemodialysis is shown to significantly improve hemoglobin, hematocrit, and red blood cell counts in adult patients who have chronic kidney disease. However, hemodialysis reduces white blood cell and platelet counts in adult chronic kidney disease patients. These modifications in hematology may have been of benefits of the clearance of uremic toxins and the reduced inflammation during dialysis. Certain of these modifications, like anemia or changes in platelets, persist beyond the process, establishing the need for further management of hematological manifestations in chronic kidney disease patients. Long-term studies are also encouraged to cover the extent of the effects of dialysis on hematological and immune functions among chronic kidney disease patients.

Background: Iron deficiency is very common and is clinically significant in patients with chronic kidney disease (CKD). It contributes to anemia and adversely affects outcomes in these patients, including quality of life, and survival. For all the advancements in our understanding of iron metabolism, the optimal methods for treating deficiency in patients with CKD continue to be an area of active research.
Objective: The focus of this review is to describe the advances in the pathophysiology, diagnosis, and management of iron deficiency in CKD, emphasizing its biomarker value and the efficacy of oral versus intravenous (IV) iron supplementation.
Methods: One hundred twenty patients with chronic kidney disease (stage 3 to 5) suffering from anemia due to iron deficiency were included in this prospective, observational study. They were assigned to either Group A (mild to moderate iron deficiency anemia [IDA], n=60) or Group B (severe IDA, n=60), according to the severity of iron deficiency. Group A received oral iron supplementation, whereas Group B received IV iron therapy. Various parameters on lab tests were measured (initial and after the treatment duration of 8 weeks) for assessment: serum ferritin, transferrin saturation (TSAT), soluble transferrin receptor (sTfR), and serum hepcidin levels. The primary outcome was change in hemoglobin levels, whereas change in iron biomarkers counted as secondary outcomes.
Results: The efficacy of IV iron therapy was superior to oral iron supplementation in increasing hemoglobin concentrations and iron parameters (p<0.05). In Group B, the mean increase in hemoglobin concentration was 2.3 g/dL, along with impressive data regarding serum ferritin, TSAT, and sTfR. Elevation in hepcidin levels was significant in severe iron deficiency, indicating that less iron was available for erythropoiesis. The comparison of sTfR as a diagnostic marker showed it to be a better indicator than the traditional markers, such as ferritin, under inflammatory conditions.
Conclusion: IV iron supplementation is better than oral iron for treating severe iron deficiency in patients with CKD, leading to better clinical outcomes. New biomarkers, such as sTfR, are much better in evaluating iron status in CKD patients than before, especially in those with concurrent inflammation. All these weighs heavily toward individualized management of the disease.

This study examines the influence of effort, growth mindset, and motivation on mathematics performance, comparing the effectiveness of traditional and machine learning regression models. Using secondary data from 4,552 students, five models—multiple regression, Random Forest, Gradient Boosting, XGBoost, and LightGBM—were evaluated for predictive accuracy and feature importance. The results demonstrate that machine learning models, particularly XGBoost, significantly outperform traditional regression, with XGBoost achieving the lowest Mean Squared Error (MSE = 7186.49) and the highest R-squared (0.1571). Effort emerged as the strongest predictor, followed by growth mindset, while motivation had a smaller but notable influence. These findings reinforce the applicability of Self-Regulation Theory and Growth Mindset Theory, highlighting the potential of machine learning to enhance educational research. Practical implications emphasize the importance of fostering effort and growth mindset through targeted interventions and leveraging predictive analytics for data-driven decision-making in education.
