In various spheres of modern industry, including power engineering, the issue of low efficiency of operation of heatexchange equipment, where condensation of vapour-gas media occurs, is a significant concern. It is known that one of the effective ways of solving this problem is intensification of heat exchange processes by transitioning from the traditional film condensation mode to the droplet condensation mode. A promising and technically straightforward way to achieve the droplet mode of condensation is a method based on the treatment of heat-exchange surfaces using a surfactant – octadecylamine (ODA). The analysis of studies, in which results of experimental research and industrial implementation are given, has shown that application of the specified method in conditions of condensation of water steam promotes formation of a stable droplet mode of condensation; as a result, the heat transfer coefficient on the steam side can more than double.Equally important and interesting is the question of how the efficiency of heat exchangers impacts the overall efficiency of complex systems, in which they operate. In this study, we examined the effect of the operational efficiency of network and regenerative heaters on the energy efficiency and economic performance of a power unit based on steam turbine unit T-110-12,8-3 operating in the heat recovery mode. To this end, we calculated the thermal scheme under various operating conditions of these heat exchangers and determined several key efficiency indicators, including the fuel heat utilisation factor (HUF) and electrical efficiency (EE). It is revealed that intensification of heat-exchange processes by a factor of 2 in horizontal delivery water heaters (HDWH) or in low-pressure heaters (LPH) significantly enhances the efficiency indicators of the power unit as a whole. At the same time, as the analysis of calculation results showed, the greatest benefits are realized when this measure is implemented in HDWH.
Documentary Practice as Praxis: A Direct Appeal to the Realization of the Social Act
Authors: Rajchinovska-Pavleska Natali 
Published: November 2024

The essential preoccupation of this paper is documentary practice as (social) praxis, the voice of the photography аs a direct mode of transmission and not only the discovery or mediation of reality. Alan Sekula's photographic discourse is taken as a case study, a practice that directly engages the subject – the position of the worker within the working class, critically representing the reality that is usually masked by spectacle. The hypotheses assume that the methodology of contextualization and discursivization of documentary photography (Untitled Slide Sequence, 1972) leads to a conscious perception of a historical and social reality. Using a cross-methodology of the author's theory and practice, referring to the author's critical point of view, Marxist and post-Marxist theories, this paper indicates that Sekula develops a specific photo-graphology concerned with the directness of expression, the literalness of meaning, and the unmasking of iconic signs captured by capitalist signifiers. The arguments underline that the use of documentary photography as a direct appeal can encourage the realization of a social act. The conclusion implies that the use of the author's voice in the direction of changing the movement of aesthetic production and reception leads to actualization, towards awakening of the passive component – confrontation with social stratification under capitalist order.
Use of multivariant enzyme-linked immunosorbent assay (ELISA) in the diagnosis of autoimmune bullous disorders in a resource-limited setting: A single-center experience
Authors: Kumar Vinod , De Dipankar , Gupta Smriti , Narayan R Vignesh , Mahajan Rahul , Chatterjee Debajyoti , Handa Sanjeev 
Published: November 2024

Background
Autoimmune blistering disorders (AIBD) result from the formation of auto-antibodies against adhesion proteins of the skin/mucosa(e). These auto-antibodies can be detected in the bound form in the tissue using direct immunofluorescence (DIF) or blood circulation using enzyme-linked immunosorbent assay (ELISA) or other methods.

Objectives
The objective of this study was to evaluate the concordance rate between the results of multivariant ELISA and the diagnosis of AIBD made using DIF and histopathology in an appropriate clinical context.

Methods
This was a retrospective study (December 2020 to April 2023) in which the multivariant ELISA assay (able to detect antibodies against desmoglein 1, desmoglein 3, BP180, BP230, envoplakin, and collagen VII) data were retrieved from the dermatology laboratory. Corresponding clinical and histopathology data were searched from relevant institutional databases. As per routine practice, the final diagnosis was assigned based on the clinical presentation, histopathology features and corresponding DIF report.

Results
After screening the records of 338 patients during the study period, 253 patients were included. Of them, 194 had AIBD and 59 had non-AIBD. In the autoimmune blistering disorder group, 122 and 72 patients had pemphigus and pemphigoid, respectively. Overall, a good level of agreement was found between multivariant ELISA results and the final diagnosis (Fleiss kappa = 0.631, p-value < 0.001). The pemphigus vulgaris group exhibited good agreement (kappa = 0.796, p < 0.001), while pemphigus foliaceous, bullous pemphigoid and non-autoimmune blistering disorders demonstrated moderate agreement (kappa = 0.641, 0.651, 0.533, respectively; p < 0.001). The mucous membrane pemphigoid group had a fair agreement (kappa = 0.289; p < 0.001).

Limitations
The limitations for the study were its retrospective design, fewer number of patients in certain groups like paraneoplastic pemphigus and gold-standard single antigen specific ELISA was not done.

Conclusion
Considering good agreement between the multivariant ELISA and the gold-standard diagnosis (clinical findings plus histopathology plus DIF), multivariant ELISA can be used for the diagnosis of AIBDs in places where facilities for DIF are unavailable. Multivariant ELISA can improve etiological diagnosis for a set of autoimmune blistering disorders whose target antigens are represented in the multivariant panel.
Effect of health education on acceptance of human papilloma virus vaccine among parents of adolescent girls of Bishnupur, Manipur: A quasi-experimental study
Authors: Dhinu K. , Fernandez Sandra , Gupta Avantika , Elangbam Vijaya 
Published: November 2024

Background & objectives
India contributes maximum to world’s cervical cancer burden. Prevention through vaccination is one of the pillars of the global strategy adopted by the World Health Organization (WHO) for the elimination of cervical cancer. Uptake of human papillomavirus (HPV) vaccine, which is about to be introduced in Universal Immunization Programme can be predicted by assessing its acceptance.

Methods
A quasi-experimental study was conducted among parents of adolescent girls of Bishnupur from February to May 2023 to evaluate the effect of a one-on-one health educational intervention programme on acceptance of the HPV vaccine. Data were collected by face-to-face interviews using a structured questionnaire based on the Health Belief Model from 70 participants selected through convenience sampling. Participants who responded ‘definitely yes’ to getting their daughters vaccinated with the HPV vaccine were considered as ‘vaccine acceptant’. Health education comprised three sessions two wk apart. Descriptive statistics, Cochrane’s Q and ANOVA were applied using SPSS 26.

Results
The median age of the participants was 38 (IQR: 34-44) yr, and 77.1 per cent were females. HPV vaccine acceptance improved significantly over time from 61.4 to 81.4 to 88.6 per cent (P=0.001), respectively. On application of repeated measure ANOVA, perceived benefits of vaccination (P<0.001) and perceived susceptibility to disease (P<0.001) improved significantly across the three time points, whereas perceived severity (P=0.051) and perceived barriers (P=0.367) did not.

Interpretation & conclusions
Health education intervention was effective at improving vaccine acceptance. Awareness programmes before the rollout of HPV vaccination and continuous re-enforcement would improve parents’ perceived benefits and thereby potentially increase vaccine coverage.
An infected intracranial dermoid cyst at the region of torcular herophili: A case report
Authors: Pahari Soumya , Bhandari Paawan Bahadur , Sharma Muna , Baniya Purushottam , Devkota Deekshya , Jha Rahul , Subedi Prarthana 
Published: November 2024

Background:
Dermoid cysts result from embryonic fusion anomalies, with intracranial dermoid cysts being rare (0.1–0.7% of intracranial tumors). Often asymptomatic, they can manifest as midline swelling, headaches, seizures, or cerebral ischemia. Recognition and management are crucial for mitigating complications and ensuring favorable patient outcomes.

Case Description:
A 14-year-old girl presented with swelling at the occiput for 3 months. Initial imaging was suggestive of an extra-dural abscess in the occipital region with surrounding bone erosion. An infectious workup, including tests for tuberculosis, was non-contributory. A suboccipital craniectomy was done. On lifting, the bone flap, thick, purulent, and sebaceous contents with hair were spotted, which was adherent to the inner table of the skull and the dura overlying the torcular herophili, suggesting an infected dermoid cyst. A near-total excision was done, and culture-directed antibiotics were given. Postoperatively, the child made a complete recovery.

Conclusion:
The diagnosis of a dermoid cyst must be kept in mind, and it should be considered in the differential diagnosis of midline posterior fossa lesions. The risk of postoperative recurrence from incomplete excision should be weighed against the risk of injuring the venous sinuses during the extensive resection of dermoid cysts adherent to the torcular region.
Rare case of resistant Achromobacter xylosoxidans-associated meningitis due to intrathecal catheter
Authors: Nair Ajay , Lucarelli Vito , Hoyt Alastair 
Published: November 2024

Background:
Achromobacter xylosoxidans (AX) is an aerobic Gram-negative opportunistic bacteria known to inhabit various environments and is most commonly associated with nosocomial infections in immune-compromised patients. Although rare, AX can cause a variety of neurological infections, such as meningitis, ventriculitis, and osteomyelitis. Intravascular catheters, intrathecal pumps, and contaminated surgical instruments are potential vectors for such patients.

Case Description:
Here, we present a unique case of multidrug-resistant AX-positive meningitis secondary to infection of a nonfunctional intrathecal narcotic pump. The patient has a complex past medical history leading up to infection, and care was significantly compromised by homelessness and inflammatory bowel disease (IBD). Treatment included catheter removal and antibiotics.

Conclusion:
Patients who suffer from homelessness or IBD show a possible increased risk of this infection. This case emphasizes the need for increased care regarding these patients, along with describing the complications and timeline when treating this rare type of meningitis.
Effectiveness of super-selective digital subtraction angiography and 3D rotational digital subtraction venography for a developmental venous anomaly with an arteriovenous malformation: A case report and literature review
Authors: Shiraishi Yuki , Neki Hiroaki , Maruyama Gakuji , Nonaka Yuko , Tokuyama Tsutomu , Tenjin Hiroshi , Saito Osamu , Kurozumi Kazuhiko 
Published: November 2024

Background:
Arteriovenous malformation (AVM) and developmental venous anomaly (DVA) rarely coexist. Developing a surgical strategy to treat this co-occurrence is difficult due to the unclear pathogenesis. We report the use of super-selective digital subtraction angiography (DSA) and Three-dimensional (3D) rotational digital subtraction venography (DSV) to develop a surgical strategy for complex AVM draining into a DVA.

Case Description:
A 58-year-old woman presented with left hemiparesis and unconsciousness. Plain and contrast computed tomography showed a right frontal subcortical hematoma and a heterogeneous contrast lesion anterior to the hematoma, leading to a dilated vessel. The hematoma was removed due to worsening unconsciousness. DSA revealed a right frontal AVM of Spetzler-Martin grade 2 with superficial drainage into a DVA, and 3D-DSV revealed that the intermediate part of the DVA involved normal parenchyma. Interventional transarterial embolization and surgical nidus removal were planned. Preoperative super-selective DSA showed two medullary veins draining from the AVM into the DVA. Thus, we decided to separate the two medullary veins from the nidus. Postoperative angiography revealed complete removal of the AVM and preservation of the DVA.

Conclusion:
Treating a complex AVM draining into a DVA is challenging; surgeons have to remove only the AVM portion and preserve the DVA. Super-selective DSA and 3D rotational DSV were performed to develop the surgical strategy.

Актуальность затрагиваемой темы определяется тем, что система таможенных органов имеет первостепенное значение в обеспечении условий внешнеэкономической деятельности Российской Федерации и, в частности, международной торговли. Роль международной торговли в условиях глобализации имеет тенденцию к возрастанию, что влечет за собой возникновение определенных угроз экономической безопасности страны (например, контрабанда, вытеснение с рынка отечественных товаров и т.д.). Следовательно, возрастает роль индикативных параметров в общем процессе. Без определения лабильности их значений само качество менеджмента может подвергаться сомнению. Поэтому авторы статьи при помощи методов индукции и дедукции, диалектического и историографического анализа, системного и процессного подходов пытаются найти и находят новые направления использования уже имеющихся индикаторов и внедрения их новых модификаций. Система многофакторных сравнений обеспечивают сделанным выводам достаточную доказательность, а значит, и убедительность.

Authors: Cheloufi Omeyr , Djedi Larbi , Chermat Tahar , Saidi Mohammed 
Published: November 2024

Objective: This Article aims to investigate the impact of oil price fluctuations on economic growth in Algeria using the Mixed Data Sampling (MIDAS) model during the period 1990-2022

Theoretical Framework: The theoretical aspect addressed the different time-frequency models by defining the Midas models and addressing the weighting functions used in estimating these models.

Method: Estimating the relationship between a high-frequency variable (oil price) and a low-frequency variable (economic growth rate GDP) using the MIDAS model using Almon's PDL Weighting Function.

Results and Discussion: The results of the study concluded economic growth in Algeria is directly affected by oil prices, The study also found that MIDAS models have a great predictive ability, allowing researchers to utilize all available information for high-frequency variables, instead of using annual average values that lose a lot of information. avoid converting low-frequency variables to match high-frequency variables, reducing econometric issues in model diagnostics.

Research Implications: Research Implications: It is suggested that rentier countries such as Algeria work to diversify their economy away from oil, and follow up the process of economic diversification and accelerate it during periods of high fuel prices by working to develop non-strategic sectors as agriculture, tourism and manufacturing industries.

Originality/Value: These results are expected to benefit policymakers in government, by urging them to invest in renewable energies as a crucial strategy for achieving sustainable development and a key factor in mitigating oil price shocks, particularly during recent recurring global crises. Future research directions include exploring existing gaps and promoting standardized studies.
The Problems of Translating Classical Arabic Embedded in Saudi Novels from a Cultural Perspective
Authors: Ghassan Nawaf Jaber Alhomoud  , Sayed M. Ismail  
Published: November 2024

This essay examines the problematic issues that arise when translating classical Arabic language embedded in contemporary Saudi literature, with a particular emphasis on Girls of Riyadh a modern Saudi novel written .The premise of the present study is that classical Arabic has undergone semantic change through pejoration amelioration, through which their original meanings have been either completely changed or different connotations have been added. When the classical Arabic terms are used in an informal context, they may acquire new connotations, the interpretation of which is totally different from their original meaning. In most cases, these classical lexical items have been transformed into dialectal lexical items. Therefore, the present study inquires whether the translation of the classical Arabic elements embedded in Girls of Riyadh effectively and comprehensively captures the impact, pragmatics, style, atmosphere, aesthetics, and culture shown in the novel. A methodology based on corpus linguistics has been employed. This study engages in descriptive research by analyzing source text-target text pairs. The corpus of the study was composed of 29 examples taken from Girls of Riyadh. The study involved categorizing selected classical Arabic phrases from the Saudi novel as cultural indicators and examining their translation using House's covert translation idea and criteria, as well as Dickins's levels of cultural transposition. The findings of this study indicate that the translators predominantly employed a communicative approach, omitting classical Arabic terms or rendering them into formal English instead of employing tactics of domestication or foreignization.

Between Discipline and Biopolitics: The Role of IOM and UNHCR in the Return of Crisis-Affected Populations
Authors: Ahouga Younes 
Published: November 2024

<p>The International Organization for Migration (IOM) and the United Nations High Commissioner for Refugees (UNHCR) return crisis-affected populations as part of their humanitarian interventions under the assumption that return represents a solution to the initial displacement. This assumption raises the question of how IOM and UNHCR problematize crisis-affected populations, that is, conceptualize them as a policy problem through policy documents reflecting implicit rationalities of government. Based on Foucault’s concepts of discipline and biopolitics and Bacchi’s approach to critical discourse analysis, this working paper examines the disciplinary and biopolitical rationalities of two policy documents. First, the IOM Migration Crisis Operational Framework (MCOF) draws on disciplinary rationality to outline a process of successive immobilization and mobilization of crisis-affected populations during which IOM monitors, cares for, transports, and immobilizes individuals in their countries of origin. Second, the UNHCR Policy Framework builds on a biopolitical rationality to elicit spontaneous returns of populations by reshaping the milieu of return through constructing infrastructure and restoring social services. However, each policy document combines both disciplinary and biopolitical rationalities. The MCOF strives to durably immobilize returnees by reshaping their milieu through infrastructure construction and resolution of land and property issues. The Policy Framework seeks to achieve durable returns by securing the milieu of return by restoring the nation-state’s disciplinary institutions. This complementarity between disciplinary and biopolitical rationalities indicates that IOM and UNHCR expanded their role in return governance to shape the economic, social, security and, ultimately, political conditions in the countries of return. </p>
5-Hydroxymethylcytosine profilings in circulating cell-free DNA as diagnostic biomarkers for DLBCL

Published: November 2024

Background5-Hydroxymethylcytosine (5hmC) is an important DNA epigenetic modification that plays a vital role in tumorigenesis, progression and prognosis. Previous studies have shown that it plays an important role in the prognosis of diffuse large B-cell lymphoma (DLBCL) and in the prediction of the efficacy of R-CHOP therapy. However, its potential for diagnosing DLBCL has not been reported. Here, we investigated the utility of 5hmC in plasma cfDNA in the diagnosis of DLBCL.MethodsApplying 5hmC-Seal technique, we obtained genome-wide 5hmC profiles in plasma cell-free DNA (cfDNA) samples from 176 Chinese subjects, included 86 DLBCL patients and 90 healthy controls. To investigate whether 5hmC can be used as a diagnostic biomarker for DLBCL, we separated patients and healthy controls into training (DLBCL = 56, Healthy = 60) and validation (DLBCL = 30, Healthy = 30) cohorts and developed a 5hmC-based logistic regression model from the training cohort to diagnose the DLBCL patients in the validation cohort.ResultsIn this study, we found 10 5hmC biomarkers, and the models created by these differentially regulated 5hmC modified genes showed high accuracy in distinguishing DLBCL patients from healthy controls (validation cohort: AUC = 0.94; (95% CI 88.8%–99.4%)).ConclusionOur study suggested that 5hmC markers derived from plasma cfDNA can served as effective epigenetic biomarkers for minimally invasive diagnosis of DLBCL.
