Published: March 2024

Мета. Розробка програмного забезпечення для кількісної оцінки росту популяції мікроводорості Chlorella.
Методика. Програмне забезпечення було розроблено за допомогою мови програмування Python та зовнішніх бібліотек: Numpy, Xlsxwriter, Matplotlib та PIL. Визначено придатність розробленого програмного забезпечення для кількісної оцінки росту популяції мікроводорості Chlorella та проведено його верифікацію. Під час верифікації оцінювали ріст популяції мікроводоростей на різних стадіях нарощування біомаси. Зразки мікроводорості Chlorella були отримані протягом декількох тижнів росту популяції.
Результати. Розроблено програмне забезпечення, яке дозволяє оцінювати ріст популяції мікроводорості Chlorella у водному середовищі. За допомогою цього програмного забезпечення отримано залежність коефіцієнта гетерогенності приросту біомаси мікроводорості Chlorella vulgaris від часу. Зростання чисельності популяції призводить до зменшення цієї гетерогенності. Цей ефект можна пояснити наявністю оптимальних умов для культивування мікроводорості Chlorella vulgaris.
Наукова новизна. Визначено вплив росту популяції мікроводорості Chlorella на гомогенність системи. Встановлено, що збільшення вмісту біомаси Chlorella vulgaris протягом 4 тижнів призводить до зниження коефіцієнта гетерогенності з 92% до 47%, що пов'язано з агрегацією мікроводорості Chlorella vulgaris у водному середовищі.
Практичне значення. Розроблене програмне забезпечення дозволяє кількісно оцінювати ріст популяції мікроводорості Chlorella vulgaris у водному середовищі та може бути використане для контролю росту біомаси водоростей у промисловому виробництві.
Висновок. Розроблено програмне забезпечення, яке дозволяє оцінити рівномірність розподілу приросту популяції мікроводоростей Chlorella vulgaris у біомасі. Його можна використовувати для дослідження рівня концентрації мікроорганізмів у водному середовищі. Результати його перевірки свідчать про придатність розробленого програмного забезпечення до практичного використання. За допомогою розробленого програмного забезпечення визначено вплив на зростання біомаси мікроводоростей Chlorella vulgaris у водному середовищі. Показано, що зростання популяції мікроводоростей Chlorella vulgaris від 1 до 4 тижнів призводить до зниження індексу змішування з 93% до 47%, що зумовлено наявністю оптимальних умов для культивування мікроводоростей Chlorella vulgaris. Методика дослідження може бути використана при розробці автоматизованих комплексів моніторингу екологічного стану водних ресурсів та контролю промислової продукції мікроводоростей Chlorella vulgaris.
Seis recomendaciones para afrontar los nuevos retos de la atención primaria. Una reflexión a la luz de las necesidades de la sociedad actual
Authors: Varela Pedragosa Jordi 
Published: March 2024

La Atención Primaria se ve envuelta en una crisis provocada por el agotamiento del modelo creado a partir de la declaración de Alma Ata de 1978, un modelo que fue de éxito pero que ahora necesita una actualización para salvaguardar sus principios de: acceso universal, orientación comunitaria, centrado en las personas, actitud proactiva y capacidad resolutiva. Para hacer viables las reformas, primero hay que analizar los lastres que las están frenando, de los cuales destacan: el sistema de asignación de cupos, la gestión indiscriminada de las agendas, el modelo organizativo excesivamente compartimentado, el escaso acento en la salud comunitaria, el modelo de gestión jerárquico y burocrático y el aislamiento respecto a otros servicios, tanto los que actúan en el mismo territorio como los hospitalarios.
Con la finalidad de preservar los principios y combatir los lastres, se proponen seis recomendaciones que deberían desenvolverse en un nuevo marco de mayor dotación presupuestaria que la actual. Las recomendaciones propuestas son: mejor gestión de la demanda, creación de equipos de cabecera para ofrecer más y mejores servicios, reorganización de acuerdo a necesidades de los distintos grupos poblacionales, redefinición de los programas de salud comunitaria a la luz de la evidencia y de las características reales de cada barrio y pueblo, ampliación de la cartera de servicios diagnósticos y terapéuticos, creando al mismo tiempo trayectorias clínicas transversales con especialistas hospitalarios y mayor implicación de usuarios y profesionales en una gestión más abierta que aprenda a rendir cuentas en lugar de estar sometida a tantos controles.

Actualmente, se carece de políticas públicas que garanticen la conectividad a Internet como un
derecho fundamental. El estudio tuvo como objetivo evaluar las políticas de inclusión digital en una
región quechua hablante del Perú a través de un enfoque cualitativo y diseño de estudio de caso;
participaron especialistas en educación y directores de educación básica regular a través de entrevistas
semi-estructuradas. Se evidenció la falta de infraestructura tecnológica para el acceso a internet y la
débil conectividad, lo que afecta la alfabetización digital de los docentes y el aprendizaje de los niños
y jóvenes. Se concluye que el acceso a internet de banda ancha, fibra óptica o satelital no es suficiente
para cumplir con los criterios de implementación de políticas de inclusión digital. Se recomienda
formar a los profesores en competencias digitales en relación con la sociedad de la información y el
conocimiento.

Preprint: ChatGPT’s Gospel Preaching Process: A Grounded Theory Study

This article has been revised and accepted for publication in
Theology and Science, published by Taylor & Francis.

Abstract:
Recent strides in Artificial Intelligence (AI) have made using AI to
automate the process of sermon preparation a possibility. However, AI’s
process of preaching is still poorly understood. This paper contributes
by evaluating 27 evangelistic sermons generated by ChatGPT using
Grounded Theory to study its process of preaching the gospel. The study
revealed ChatGPT’s use of sharing personal testimony, delivering the
gospel as found in the Bible, and appealing to unbelievers to preach the
gospel. The necessity of the transformative power of the gospel was
identified as the core category. Theological comprehensiveness and
orthodoxy of the sermons were also evaluated.
NextGenPower – Demonstration and Component Fabrication of Nickel Alloys and Protective Coatings for Steam Temperatures of 750°C
Authors: Stam Arthur F. 
Published: March 2024

Abstract
The EU NextGenPower-project aims at demonstrating Ni-alloys and coatings for application in high-efficiency power plants. Fireside corrosion lab and plants trials show that A263 and A617 perform similar while A740H outperforms them. Lab tests showed promising results for NiCr, Diamalloy3006 and SHS9172 coatings. Probe trials in six plants are ongoing. A617, A740H and A263 performed equally in steamside oxidation lab test ≤750°C while A617 and A740H outperformed A263 at 800°C; high pressure tests are planned. Slow strain rate testing confirmed relaxation cracking of A263. A creep-fatigue interaction test program for A263 includes LCF tests. Negative creep of A263 is researched with gleeble tests. A263 Ø80 - 500mm trial rotors are forged with optimized composition. Studies for designing and optimizing the forging process were done. Segregation free Ø300 and 1,000mm rotors have been forged. A263 – A263 and A293 – COST F rotor welding show promising results (A263 in precipitation hardened condition). Cast step blocks of A282, A263 and A740H showed volumetric cracking after heat treatment. New ‘as cast’ blocks of optimized composition are without cracks. A 750°C steam cycle has been designed with integrated CO2 capture at 45% efficiency (LHV). Superheater life at ≤750°C and co-firing is modeled.
Fabrication Trials of Ni-Based Alloys for Advanced USC Boiler Application
Authors: Saito Nobuhiko , Komai Nobuyoshi , Takei Yasuhiro 
Published: March 2024

Abstract
In order to reduce CO2 emissions and improve power generation efficiency, a development project involving an advanced USC (A-USC) plant has been carried out in Japan since 2008. Nibased alloys are candidate materials for boiler components with high temperature steam conditions, which are much stronger than conventional heat resistant steel. However, Ni-based alloys have never been applied with respect to the high pressure parts and thick walled components of USC coal-fired power plants. In this study, therefore, fabrication and characteristic properties, such as weldability, the weld joint and bent part properties, and weld cracking susceptibilities of Ni-based alloys such as HR6W, HR35 and two types of Alloy617 (High B and Low B) pipes were evaluated. Additionally, two types of HR6W header mock-ups and a HR6W tube element mock-up were fabricated. With the exception of Alloy617 (High B), the fabrication trials of Ni-based alloy pipes were conducted successfully, and the long-term creep strength of weldments and bends of Ni-based alloy pipes were found to be nearly equivalent to those of base metal. In the case of Alloy617 (High B), hot cracking was observed.
Investigation of Creep Damage and Cavitation Mechanisms in P92 Steels
Authors: Gu Y. , West G.D. , Thomson R.C. , Parker J. 
Published: March 2024

Abstract
Contrary to expectations, long-term performance of creep stress enhanced ferritic steels (CSEF) falls short of predictions based on short-term data. This discrepancy is attributed to the formation and growth of creep voids, leading to reduced ductility. This study investigates cavities in creep-tested P92 steel, revealing an association with large ceramic particles (1-2 μm) in standard samples. Three distinct particle compositions were identified: boron nitride (BN), manganese sulfide, and γ-Al2O3. Statistical analysis showed a strong correlation between BN particles and cavity formation. Using a 3D “slice and view” technique with a focused ion beam/field emission gun scanning electron microscope (FIB-FEGSEM), the study revealed irregular shapes for both cavities and associated particles. Furthermore, analysis of the head-gauge transition area (lower stress exposure) showed small cavities near BN particles, suggesting preferential nucleation on these hard, irregular features. These findings strongly support the hypothesis that BN particles play a key role in cavity nucleation, impacting the long-term performance of P92 steel.
Managing Oxide Scale Exfoliation in Boilers with TP347H Superheater Tubes
Authors: Sabau Adrian S. , Wright Ian G. , Shingledecker John P. , Tortorelli Peter F. 
Published: March 2024

Abstract
A model based on a concept of “fraction of exfoliated area” as a function of oxide scale strain energy was developed to predict the extent of exfoliation of steam-side scale from boiler tube superheater loops. As compared with the Armitt diagram, which can be used to predict when scale damage and exfoliation would be likely to occur, a “fraction of exfoliated area” approach provides an estimation of mass of scale released and the fraction of tube likely to be blocked by the exfoliation. This paper gives results for the extent of blockage expected in a single bend of a superheater loop was predicted as a function of operating time, bend geometry, and outlet steam temperature under realistic service conditions that include outages. The deposits of exfoliated scale were assumed to be distributed horizontally the tubes bends. Three types of bends were considered: regular bends, short bends, and hairpin bends. The progressive increase in steam and tube temperatures along a single loop of superheater tubing and the ensuing variation of oxide scale thickness are considered. Numerical simulation results for a superheater loop made of TP347H austenitic steel indicated that tube blockage fractions larger than 50% are likely to occur within the first two years of boiler operation (with regularly scheduled outages) for outlet tube temperatures of 540-570°C, which is consistent with practical experience. Higher blockage fractions were predicted for tubes with hairpin bends than for tubes with regular bends, of length that are larger than five internal tube diameters. Finally, the blockage model presented can be used with some confidence to devise operating schedules for managing the consequences of oxide scale exfoliation based on projections of time to some critical blockage fraction for specific boiler operating conditions.

Authors: Li Lin , Li Ju , He Mu 
Published: March 2024

BACKGROUND: Acupuncture, traditional Chinese herb hot compress and rehabilitation training is useful in post-stroke shoulder–hand syndrome (SHS), but it is less commonly used in combination. OBJECTIVE: To analyse the therapeutic efficacy of a combination of acupuncture, traditional Chinese herb hot compress and rehabilitation training in SHS patients. METHOD: Patients diagnosed with post-stroke SHS and treated from January 2022 to March 2023 at Beijing Friendship Hospital and Beijing Pinggu Hospital were selected and randomly divided into three groups (A, B and C). Group A received conventional rehabilitative treatment (35 cases), Group B underwent conventional rehabilitative treatment + acupuncture (35 cases), and Group C received conventional rehabilitative treatment + acupuncture + traditional Chinese herb hot compress treatment (35 cases). The post-treatment effectiveness rate, visual analogue scale (VAS) score, activities of daily living (ADL) score, Fugel–Meyer assessment (FMA) score, SHS assessment scale (SHSS) score and shoulder joint mobility were compared among the three groups. RESULTS: The post-treatment VAS score (FVAS score= 232.512, P< 0.001), FMA score (FFMA score= 239.412, P< 0.001), ADL score (FADL score= 412.634, P< 0.001), SHSS score (FSHSS score= 212.542, P< 0.001) and shoulder joint mobility (FShoulder Joint Mobility= 197.531, P< 0.001) all showed statistically significant differences. The VAS and SHSS scores decreased in the order of Group A > Group B > Group C, while the FMA, ADL and shoulder joint mobility scores increased in the order of Group C > Group B > Group A. The post-treatment effectiveness rates (χ2= 48.510, P< 0.001) also exhibited statistically significant differences, decreasing in the order of Group C (94.29%) > Group B (82.86%) > Group A (71.43%). CONCLUSION: The treatment efficacy of the combined acupuncture, traditional Chinese herb hot compress and rehabilitation training for SHS patients is significant, warranting its clinical promotion.
Identification of a prognostic signature based on five ferroptosis-related genes for diffuse large B-cell lymphoma
Authors: Li Wuping , Yao Ruizhe , Yu Nasha , Zhang Weiming 
Published: March 2024

BACKGROUND: Therapies for diffuse large B-cell lymphoma (DLBCL) are limited due to the diverse gene expression profiles and complicated immune microenvironments, making it an aggressive lymphoma. Beyond this, researches have shown that ferroptosis contributes to tumorigenesis, progression, and metastasis. We thus are interested to dissect the connection between ferroptosis and disease status of DLBCL. We aim at generating a valuable prognosis gene signature for predicting the status of patients of DLBCL, with focus on ferroptosis-related genes (FRGs). OBJECTIVE: To examine the connection between ferroptosis-related genes (FRGs) and clinical outcomes in DLBCL patients based on public datasets. METHODS: An expression profile dataset for DLBCL was downloaded from GSE32918 ( https://www.ncbi.nlm.nih.gov/geo/ query/acc.cgi?acc=gse32918 ), and a ferroptosis-related gene cluster was obtained from the FerrDb database ( http://www. zhounan.org/ferrdb/ ). A prognostic signature was developed from this gene cluster by applying a least absolute shrinkage and selection operator (LASSO) Cox regression analysis to GSE32918, followed by external validation. Its effectiveness as a biomarker and the prognostic value was determined by a receiver operator characteristic curve mono factor analysis. Finally, functional enrichment was evaluated by the package Cluster Profiler of R. RESULTS: Five ferroptosis-related genes (FRGs) ( GOP1, GPX2, SLC7A5, ATF4, and CXCL2) associated with DLBCL were obtained by a multivariate analysis. The prognostic power of these five FRGs was verified by TCGA ( https://xenabrowser.net/datapages/?dataset=TCGA.DLBC.sampleMap%2FHiSeqV2_PANCAN&host=https%3A%2F%2Ftcga.xenahubs.net&removeHub=https%3A%2F%2Fxena.treehouse.gi.ucsc.edu%3A44 ) and GEO ( https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=gse 32918 ) datasets, with ROC analyses. KEGG and GO analyses revealed that upregulated genes in the high-risk group based on the gene signature were enriched in receptor interactions and other cancer-related pathways, including pathways related to abnormal metabolism and cell differentiation. CONCLUSION: The newly developed signature involving GOP1, GPX2, SLC7A5, ATF4, and CXCL2 has the potential to serve as a prognostic biomarker. Furthermore, our results provide additional support for the contribution of ferroptosis to DLBCL.
Adipokine vaspin maintains angiogenesis and neurological function during cerebral ischemia-reperfusion via suppressing endoplasmic reticulum stress
Authors: Yan Wentao , He Xiuhua , Wang Guanjun , Hu Guochao , Cui Bin 
Published: March 2024

INTRODUCTION: Visceral adipose tissue-derived serine protease inhibitor (vaspin) is an adipokine. It has been reported that decreased serum vaspin levels are significantly associated with stroke severity and prognosis. OBJECTIVE: This article aims to explore the theoretical feasibility of vaspin supplementation for cerebral ischemia-reperfusion (I/R) injury. METHODS: The I/R mouse models were constructed by the middle cerebral artery occlusion (MCAO) method, and the effects of vaspin on cerebral infarction, neurological function, angiogenesis and endoplasmic reticulum (ER) stress were explored. To verify the mediation of ER stress in the regulation of vaspin, human brain microvascular endothelial cells (HBMECs) were subjected to ER stress agonist tunicamycin in vitro. The impacts of vaspin and tunicamycin on oxygen glucose deprivation/ recovery (OGD/R)-induced cell viability, apoptosis, and angiogenesis were examined. RESULTS: Vaspin inhibited blood-brain barrier breakdown and infarction occurred in the brain tissue of the I/R mice. Vaspin also enhanced cerebral neovascularization and reduced the apoptosis. Additional tunicamycin increased the apoptosis of HBMECs and inhibited angiogenesis, reversing the protective effect of vaspin on cells. CONCLUSION: Together, this study reveals that vaspin supplementation reduces cerebral infarction and works against neurological dysfunction. It maintains the survival and angiogenesis capacity of HBMECs by inhibiting ER stress.

BACKGROUND: Cryotherapy is widely utilized for therapeutic purposes, yet its specific effects on knee joint proprioception and quadriceps muscle performance in healthy individuals remain unclear. This study addresses this gap by examining the impact of a 20-minute cryotherapy session on knee joint proprioception and related muscle parameters in a cohort of healthy college students. OBJECTIVES: To investigate the effects of cryotherapy on knee joint proprioception and quadriceps muscle peak moment, work and power in healthy college male and female students. METHODS: Thirty-two healthy students, aged 19–23, underwent a 20-minute cryotherapy session using Cryogel packs applied to the anterior thigh and knee. An isokinetic dynamometer measured knee joint proprioception and quadriceps muscle parameters before, immediately after, 10-min, and 20-min post-cryotherapy. RESULTS: Proprioception values did not significantly differ between genders or post-tests ([Formula: see text] 0.05). However, the female group exhibited significantly lower moment, power, and work values compared to males ([Formula: see text] 0.05). No significant differences were observed within or between post-tests in moment, power, and work for both genders ([Formula: see text] 0.05). CONCLUSIONS: A 20-minute cryotherapy application demonstrated no adverse effects on knee joint proprioception or quadriceps muscle metrics in healthy college students, supporting the safety of cryotherapy in this context.
