Published: October 2024

Стаття присвячена питанню дослідження підвищення ефективності газорозподільних станцій за рахунок модернізації та технічного переозброєння. Розглядається проблема ефективного використання потенційної енергії природного газу на газорозподільних станціях систем газопостачання. Зниження тиску газу при переході від магістрального газопроводу до системи розподілу здійснюється в процесі дроселювання газу у вузлу редукування газорозподільної станції. В такому процесі потенційна енергія газу втрачається, не виконуючи роботи.
У статті пропонується підвищити ефективність перетворення потенційної енергії газу в електричну енергію за рахунок впровадження турбодетандерних установок. Утилізуючи системи, засновані на турбодетандерних електрогенераторних установках та агрегатах, забезпечують одночасно зниження та регулювання тиску газу при його розширенні в машині, а також отримання механічної роботи на валу з перетворенням її на електроенергію.
Підвищення ефективності газорозподільних станцій можливе за рахунок повної модернізації станції за умови економічної доцільності, або з використанням обмежених маловитратних заходів з реконструкції окремих вузлів або трубопровідної обв’язки станції. У статті проаналізовано підвищення енергетичної ефективності технологічних процесів газорозподільної станції шляхом застосування маловитратних заходів. Виявлення резервів пропускної здатності газорозподільної станції і реконструкція окремих ділянок станції з метою підвищення пропускної здатності дають можливість використовувати станцію в умовах збільшеного навантаження, тобто забезпечити відповідність проектної і експлуатаційної продуктивності газорозподільної станції.
Сформовано математичну модель дослідження течії газу в газопроводі лінії редукування після регулятора тиску газу та встановлено граничні умови для проведення розрахунків. За допомогою математичної моделі виконано моделювання течії газу в лінії редукування після клапана регулятора тиску за різних умов роботи. Наведено термодинамічний розрахунок одного з варіантів маловитратного заходу. Наведено результати, що підтверджують можливість утилізації енергії стисненого природного газу в процесі редукування навіть за високої нерівномірності відбору газу споживачами.

Authors: Busch Deborah W. , Moss Davina A. , Barrick Christopher 
Published: October 2024

Objective:The PeriWell project integrates the Positive Direction Model and the Tri-Core Breastfeeding Model into a virtual support program tailored to peripartum mothers in substance use recovery. PeriWell addresses the unique challenges this population faces by offering tailored, wraparound support. This manuscript, part of a two-part series, highlights the project’s outcomes, demonstrating significant implications for maternal health practices by fostering an environment of empowerment and lactation wraparound support.Methods:This longitudinal quality improvement (QI) project spanned 24 months (2019–2021) during the COVID-19 pandemic. It involved 15 peripartum mothers in substance use recovery engaging in a virtual, single-site program. The project was approved as a QI initiative by the Institutional Review Board (IRB reference 2018-19, #89), ensuring ethical adherence and participant safety. Participants provided voluntary consent and were recruited from obstetrics and gynecology offices in Upstate New York. To evaluate participants’ confidence and belief in their breastfeeding abilities, we received author permission and utilized the validated Breastfeeding Self-Efficacy Scale-Short Form (Dennis & Faux, 1999; Dennis, 2010), guiding the tailored support provided.Results:Results indicated a significant increase in prenatal breastfeeding confidence correlated with the PeriWell approach (r= .782,n= 14,p< .001). Participants reported improved self-confidence in latching techniques and a greater appreciation of the time commitment required for successful breastfeeding. Correlational relationships provided valuable insight to enhance and amplify breastfeeding support. The findings advocate for the inclusion of targeted specialized interventions in maternal care to better meet the needs of expecting individuals.Conclusion:Cultivating a supportive peripartum environment is fundamental to maternal-child healthcare, and the PeriWell project demonstrated the efficacy of integrating tailored, virtual peripartum and breastfeeding support for expecting and postpartum mothers in substance use recovery. This quality improvement project improved maternal and infant health outcomes, such as breastfeeding self-efficacy, and highlighted the importance and value of specialized, wraparound lactation support for vulnerable populations. These findings underscore the need for continued innovation in maternal health services, particularly through empowerment and promoting breastfeeding success in recovery settings.

Published: October 2024

The phenomenon of 'massification in higher education ', which refers to the significant increase in the number of students enrolling in universities, has made it difficult for inclusive education to be attainable owing to unknown reasons that are encumbering the students living with disability from having a sense of belonging. Hence, this study aims to evaluate the relationship between students living with disability and social justice through inclusivity in higher education with the aid of Assistive Technology (AT) to conceptualise a framework. The researchers employed a mixed methods approach to collect and analyse data statistically and descriptively. The requirements for integrating the model to ease the lack of consideration of students living with disability in the digital age were evaluated and critically reviewed regarding its impact on students’ sense of belonging in the digital age. The major findings from this study elucidate the factors perceived as the central requirements for mitigating the lack of inclusivity and social justice in higher education. The procurement of ATs was topical as most respondents (83%) categorically opined the need to improve this process by making timely purchases of the proper ATs from reliable service providers. The successful implementation of this framework could significantly enhance the educational experience of students with disabilities at the University of Venda, making it a more inclusive and supportive learning environment. The findings on the appropriateness of ATs for students overwhelmingly indicated that many of the available devices and technologies meant to assist learners were not fit for the tasks they were intended for. The university should establish a procurement committee and a high-level action plan outlining the requirements for delivering assistive products & services.
Exploring the influence of ‘Korean Wave’ on brand loyalty: The moderating role of product type
Authors: Lady Lady , Meilani Lara , Cuandra Fendy , Na Bai 
Published: October 2024

The ‘Korean Wave’ has significantly impacted the global economy, especially in Indonesia. However, there is a gap in understanding how Korean celebrities, as brand ambassadors, influence local consumer behavior and purchase intentions. This study aims to clarify this impact using the theory of planned behavior (TPB) framework. The roles of brand attachment, brand love, and brand loyalty, moderated by product type, were examined with 194 survey respondents, and data was analyzed using SmartPLS software. Key findings indicate that brand personality significantly influences brand attachment. Customer brand engagement positively affects brand love. Brand attachment impacts both brand loyalty and brand love, while brand love strongly influences brand loyalty. Brand loyalty significantly affects purchase intentions, confirming that loyal customers are more likely to make repeat purchases. Product type only moderates the influence of brand attachment on brand loyalty, not the influence of brand love on brand loyalty. The implications for marketers are significant. Businesses should leverage Korean celebrities as brand ambassadors to enhance brand visibility and loyalty. Aligning brand personality with ambassadors can deepen consumer attachment. Creating engaging content and focusing on emotional branding can foster stronger connections. Tailoring marketing strategies to different product types and monitoring brand loyalty feedback can enhance market performance. Despite its contributions, the study acknowledges limitations, including potential demographic biases and the need for broader cultural and product category exploration in future research.
A novel approach for Plant disease Classification through Neural Network-Based Color Feature Analysis
Authors: KS Archana , S Arun 
Published: October 2024

Abstract

plant disease identification using machine vision, which is a challenge in terms of maximizing both the quality and quantity of plant growth. The infection makes plants susceptible to disease. This needs continuous monitoring by experts, which is prohibitively expensive in large farms, but in some instances, erroneous observations by farmers culminate in poor diagnoses. Consequently, we need a fast and accurate plant disease diagnosis predicted to increase the area under cultivation, eliminate heavy losses, and ensure high accuracy. The focus must be on identifying early symptoms of plant disease using computer vision. In order to solve this problem, deep learning can combine machine learning and pattern recognition, two hottest topics in this field. We propose a novel method to identify different plant diseases using deep convolutional neural networks (CNNs). In this study, we propose an image-based classification approach for rice plant diseases, focusing solely on color features. We investigated 12 distinct color spaces and derived 4 features from each color channel, resulting in a total of 48 features. The accuracy of this model is much higher than that of traditional machine learning models. Using the best-performing model, we achieved a classification accuracy of 96.03%. The simulation results show that the proposed method for identifying plant diseases is effective and feasible.

Abstract

Disrupted cytokine networks and autoantibodies play an important role in the pathogenesis of systemic lupus erythematosus. However, conflicting reports and non-reproducibility have hindered progress regarding the translational potential of cytokines in SLE. This study attempts to address the existing knowledge gap using multiplex cytokine assay and machine learning. 67 SLE patients fulfilling SLICC criteria were recruited after informed consent, and circulating cytokines were measured by multiplex cytokine assay kit. We observed a positive association between actual disease activity scores (SLEDAI) and predicted scores from a partial least squares regression (PLSR) analysis of multivariate cytokine response data, with MIP-1α having a strong contribution towards disease activity. Our analysis also highlights increased IL-17 as a potential biomarker in nephritis and elevated MIP-1α as a signature of NPSLE. Using a k-Modes clustering algorithm to stratify patients based on patterns of co-occurrence of circulating autoantibodies, we identified 4 distinct clusters of patients. Our analysis revealed a striking difference in the distribution of lupus nephritis between the clusters, with all patients in cluster 3 presenting with nephritis with significantly low levels of housekeeping and homeostatic cytokines and the presence of anti-Ro antibodies, which is a novel observation. Thus, we demonstrate that cytokines can be a surrogate to predict disease activity and organ involvement in SLE. Moreover, we show the utility of unsupervised machine learning algorithms combining specific autoantibody and cytokine signatures to predict renal involvement in SLE.
TERT mutations in Malignant Melanoma-Survival Meta-Analysis
Authors: Hahn Hyung Jin , Kim Hyun Ji 
Published: October 2024

Abstract

It has long been speculated that the TERT promoter mutation is linked to poor patient survival in malignant melanoma. However, this notion is still in contention, as evidenced by conflicting study results. Therefore, the authors took on a quantitative synthesis in order to gain a better grasp of the role of TERT mutation in melanoma and to further assess the feasibility of taking advantage of the defect as a prospective target in molecular targeted therapy PubMed, EMBASE, Cochrane, MEDLINE, Google Scholar, and other databases were searched with keywords such as "malignant melanoma". "TERT promoter mutation", and "survival". Hazard ratios, in disease‑specific and overall survival, were calculated for each survival-determining variable. Overall, MM patients with mutated TERT promoters were roughly 60% more likely to experience death compared to non-mutated individuals (pooled HR = 1.64). In subgroup analysis, age did not play much role in survival, but male sex, ulceration, acrally located lesions, high Breslow thickness, presence of mitosis, and higher clinical stages were notable factors in poor prognosis. When the TERT promoter is mutated concurrently with other common mutations, such as B-raf, N-ras, and c-kit, the hazard of death is much greater (pooled HR = 2.75). In conclusion, targeting TERT mutation may be one of the missing puzzles for effective targeted therapy in MM, as it influences and interacts with other common mutations.

Authors: Huang Zhaolan , Gao Hui , Tan Wei , Qu Lailai , Cheng Xi 
Published: October 2024

Abstract

Background
Walking speed, as a simple measurement indicator, is valuable in assessing the motor function of the elderly and predicting hospitalization and mortality rates. This study utilizes physical examination data from community health service centers for individuals aged 65 and above, focusing on walking speed to explore the factors influencing substandard walking speed.
Methods
From January 2022 to December 2022, elderly individuals who underwent physical examinations at Qingling Community Health Service Center were selected. Based on inclusion and exclusion criteria, a total of 4865 participants were eligible. According to walking speed results, participants were divided into two groups: the qualified group (≤ 8 seconds) with 3889 people (73.8%) and the unqualified group (> 8 seconds) with 1276 people (26.2%). Additional information on the participants was obtained through the electronic information system. A comparison of relevant information between the two groups was conducted to summarize the influencing factors of walking speed, with P < 0.05 indicating statistical significance.
Results
Age, marital status, caregiving situation, weekly exercise routine, drinking habits, height, weight, BMI, blood urea nitrogen, low-density lipoprotein, Chinese visceral adiposity index, cardiometabolic index, and systemic immune-inflammation index are all risk factors for decreased walking speed. ROC curve analysis showed that the systemic immune-inflammation index had the best predictive efficiency.
Conclusion
Marital status, caregiving situation, weekly exercise routine, and drinking habits are all correlated with decreased walking speed. Age, weight, waist circumference, and the systemic immune-inflammation index (SII) are positively correlated with decreased walking speed. In contrast, height, BMI, blood urea nitrogen, LDL-C, Chinese visceral adiposity index (CVAI), and cardiometabolic index (CMI) are negatively correlated with decreased walking speed. Among these factors, SII has the strongest predictive efficiency for decreased walking speed.

Abstract

A 4-year-old male axis deer (Axis axis) died after several weeks of progressive weight loss and severe respiratory distress. A field necropsy was performed, and lung tissue was submitted for histopathology. Microscopically, there was severe, subacute to chronic, diffuse, suppurative bronchopneumonia with multiple caseonecrotic foci and bronchiectasis. Immunohistochemical (IHC) analysis using polyclonal antibodies for Mycoplasma bovis revealed positive immunoreactivity. The histopathological, and IHC findings observed in this deer are remarkably similar to pulmonary mycoplasmosis of cattle. These findings represent the first report of M. bovis-associated pneumonia in the axis deer and suggest that deer develop pulmonary disease and lung lesions like mycoplasmosis in domestic cattle.
Essential Thrombocythemia Complicated by Multivessel Intracranial Dolichoectasia with Subarachnoid Hemorrhage and Recurrent Cerebral Infarction: A Case Report
Authors: KINOUCHI TOMOYA , Takeuchi Kyoko , Uyama Shinichi , Miyamoto Tadashi , Ueta Hiromi 
Published: October 2024

Abstract

Background: Patients with essential thrombocythemia (ET) can develop systemic thrombotic and hemorrhagic vascular complications due to increased and dysfunctional platelets.
Case presentation: We encountered a 49-year-old Japanese woman with a history of essential ET, cerebral infarction, hypertension, and hyperlipidemia. She had been taking anagrelide (2.5 mg/day) and aspirin (100 mg/day) and had vomited at home. At the time of admission to our hospital she was in a deep stupor. Head computed tomography showed severe subarachnoid hemorrhage (SAH) at the interhemispheric fissure, hematoma at the corpus callosum, and intraventricular hemorrhages. Digital subtraction angiography demonstrated multiple dilated, stenotic, tortuous intracranial arteries, and a dissecting aneurysm at the right anterior cerebral artery (ACA). The dissecting aneurysm measured 7.7 × 15.5 mm and a bleb was observed. Our diagnosis was ruptured ACA dissecting aneurysm and diffuse intracranial arterial dolichoectasia (DIADE). We performed stent-assisted coil embolization of the aneurysm. She remained apathetic and manifested unilateral apraxia and alien limb syndrome due to a partial callosal disconnection. Two months thereafter her symptoms gradually improved, her consciousness level and limb function improved and her modified Rankin scale (mRS) score was 2. However, when we tapered her antiplatelet therapy she again developed an acute cerebral infarct.
Conclusions: This is the first presentation of a patient with ET complicated by DIADE, both of which can result in ischemic and hemorrhagic vascular complications including SAH. As antithrombotic therapy in patients with DIADE and ET may be associated with higher hemorrhage rates, its effects must be monitored carefully.

Abstract

Purpose
We aimed to evaluate the utility of surveillance contrast-enhanced chest computed tomography (CT) in detecting second primary breast cancer among breast cancer survivors, focusing on imaging and clinicopathological features contributing to tumor visibility. Additionally, we sought to provide insights into which patient populations benefit from contrast-enhanced chest CT.
Methods
We retrospectively analyzed records of patients diagnosed with in-breast recurrence through biopsy during surveillance follow-up after curative breast cancer surgery between January 2016 and August 2022. Patients who underwent contrast-enhanced chest CT within 1 month of diagnosis were included. Two radiologists reviewed chest CT scans for breast cancer lesions by consensus, and their findings were validated by two other radiologists blinded to tumor locations. Statistical analyses were performed to evaluate associations among clinicopathological factors, image features, and visibility.
Results
Eighty-nine recurrent tumors in 85 patients were included. Of these, 58 recurrent tumors were identified by the unblinded radiologists. The blinded radiologists independently identified 50 and 56 recurrences, with substantial inter-observer agreement. The visible group had a higher rate of invasive ductal carcinoma (IDC) and larger tumor sizes than those of the non-visible group. Tumors in fatty backgrounds exhibited greater visibility on chest CT than those in glandular tissues. Logistic regression analysis revealed that mastectomy patients had significantly increased visibility of recurrent tumors on chest CT.
Conclusion
Contrast-enhanced chest CT is valuable for detecting recurrent breast cancer, especially in mastectomy patients. Tumors in fatty backgrounds, larger tumors, mass-type tumors, and IDC are better visible on chest CT.

Abstract

Purpose
The aim of this study was to compare stem revision and ORIF for the treatment of Vancouver B2 periprosthetic fractures of the femur.
Methods
From June 2012 to May 2022, 56 consecutive patients were studied at our institution. Four patients were lost to follow-up, four had incomplete data. Thus, 48 cases were included in the analysis. The patients were divided into a stem revision group (SR, group 1 with 25 patients) and an open reduction and internal fixation group (ORIF, group 2 with 23 patients). The surgical complications, perioperative parameters, and 1-year mortality rates were assessed, the functional outcomes were assessed with the Harris Hip Score, and the radiographic outcomes were assessed in accordance with the Beals and Tower criteria.
Results
In group 1, the mean follow-up time was 41.2 months, 40% of patients experienced complications, the mean HHS was 75.27, and 92% of the patients had “excellent–good” radiographic outcomes. In group 2, 21.7% of patients experienced complications, the mean HHS was 73.56, and 91.3% of the patients had “excellent–good” radiographic outcomes. The total number of postoperative complications, dislocation rate, blood loss volume, operation time and transfusion rate were lower in group 1 (ORIF), and two patients in group 2 (SR) experienced hip dislocation. There were no significant differences in the 1-year mortality rate, bone healing time or reoperation rate between the two groups. However, the time to total weight-bearing in the SR group was shorter than that in the ORIF group, and the radio subsidence rate in the SR group was lower than that in the ORIF group, especially for patients with poor compliance. The postoperative quality of life of the patients in the two groups was worse than their original quality of life before fracture.
Conclusions
Stem revision and ORIF are effective treatments for Vancouver B2 fractures. However, ORIF can be an option for elderly patients with several medical disorders, while stem revision is advantageous in terms of earlier weight bearing.
