Solar PV power forecasting at Yarmouk University using machine learning techniques
Authors: Alhmoud Lina , Al-Zoubi Ala’ M. , Aljarah Ibrahim 
Published: January 2023

AbstractRenewable energy sources are considered ubiquitous and drive the energy revolution. Energy producers suffer from inconsistent electricity generation. They often struggled with the unpredictability of the weather. Thus, making it challenging to balance supply and demand. Technologies like artificial intelligence (AI) and machine learning are effective ways to forecast, distribute, and manage renewable photovoltaic (PV) solar supplies. AI will make the energy forecasting system more connected, intelligent, reliable, and sustainable. AI can innovate how energy is used and help find solutions for decarbonizing energy systems. There are potential advantages to total energy forecasting. AI can support the growth and integration of PV solar energy. The article’s main objective is to use AI to forecast the output consumed power of the Yarmouk University PV solar system in Jordan. The total actual yield is 5548.96 MW h, and the performance ratio (PR) is 95.73%. Many techniques are used to predict the consumed solar power. The random forest model obtains the best results of root mean squared error and mean absolute error are 172.07 and 68.7, respectively. This accurate prediction allows for the maximum use of solar power and the minimal use of grid power. This work guides the operators to learn trends embedded in Yarmouk University’s historical data. These understood trends can be used to predict the consumption of solar power output. Thus, the control system and grid operators have advanced knowledge of the expected consumption of solar power at each hour of the day.
Narrating pain: The power of storytelling in Maryam Madjidi’sMarx et la poupée
Authors: den Toonder Jeanette 
Published: January 2023

AbstractThis article explores the positioning of the immigrant self in the story-world by elaborating on the unsettling experience of migration and analyzing the discursive (re)construction of identity in the novelMarx et la poupée[Marx and the Doll] by Franco-Iranian writer Maryam Madjidi. In order to reconstruct her dissolved self, the protagonist and narrator tells her story of pain and suffering caused by alienation and the struggle between two conflicting identities, the Persian and the French. Through the act of storytelling, this article argues, immigrant suffering is translated into narrative. The theoretical framework explores translation as a narrative tool and also reflects on how the act of storytelling grants the immigrant subject agency and invites readers to engage with their painful experience. The first part of the analysis examines the protagonist’s suffering by focusing on her refusal to eat and loss of language. The second part analyses how she recreates her painful experiences by inventing tales and presenting events and memories in a dreamlike fashion, while also critically addressing her encounters with the new culture. The stories allow for a reflection on and a possible reconciliation of the two conflicting identities and invite the readers to become aware of the complexity of the immigrant’s suffering.
Dirty politics: The stories of soap in South Africa
Authors: van der Waal Margriet 
Published: January 2023

AbstractDuring the global Covid-19 pandemic, the practice of extensively washing one’s hands with soap and water became ubiquitous worldwide. In this contribution, I look at how cultural references to soap have been productive in producing social identities in South Africa. By utilizing Nira Yuval-Davis’s (2006) distinction between belonging and the politics of belonging, I trace how stories and narratives featuring soap that circulate in the South African cultural archive refer to specific cultural templates or social imaginaries. These stories and narratives perform different functions: they signify categories of social belonging, enable social subjects to identify with specific subject locations, and are utilized to both confirm and patrol the borders of these categories of belonging in acts that may be described as the “politics of belonging.”
“Or even Frisian, yes. No, no”: The negotiation of space for a minority language in narratives by pre-service teachers
Authors: Moenandar Sjoerd-Jeroen , Lucaci Miruna , Duarte Joana 
Published: January 2023

AbstractNegative attitudes towards minority languages in educational settings can have far-reaching consequences for pupils’ academic achievement and well-being, yet they prevail in most education systems. The current study adds to research on language attitudes in education by analysing the narrative negotiation of the value of Frisian, a minority language from the northern Netherlands. For this analysis, a number of narratives on experiences with Frisian in a variety of learning environments will be discussed. These narratives come from interviews (n=8) that were selected from a larger corpus of semi-structured interviews on multilingualism in education with pre-service teachers from the northern Netherlands. Our analysis shows that in these narratives, Frisian is continuously cast as having to be neutralised, as it threatens classroom order, academic success, and the quality of teaching. Even in narratives that instead propose Frisian as something positive, the language needs to be somehow managed, often by ascribing it to a marginalised space, thus reifying implicit or explicit language hierarchies, as well as the supposedly peripheral, rural, and outdated character of this language. This study paves the way for future research on the regulating effects of dominant narratives for the value of minority languages in actual learning environments.

Published: January 2023

Abstract
In order to improve the high temperature melting characteristics of bituminous coal with low ash melting point, three kinds of anthracites were used to improve the ash melting characteristics of blended coal to meet the requirement of blast furnace injection. The complete melting temperature of pulverized coal ash had been calculated by using FactSage thermodynamic calculation software. The results showed that after adding different proportions of anthracite with high ash melting point, the deformation temperature, softening temperature, hemispherical temperature, and flow temperature of the blended coal increased. After adding different proportions of Yang Quan anthracite, compared to Bu Lian Ta bituminous coal, the ash melting point of blended coal increased by 98, 136, 149, and 170 K, respectively. The relationship between the ash melting point of pulverized coal and the calculated value of ash complete melting temperature was obtained as: T
ST = 0.7098T
C + 257.98.

„Wir können nur den lieben Gott bitten, daß der Krieg recht bald zu Ende ist“ – Christliche Familien und die Erfahrung des Zweiten Weltkrieges
Authors: Kiefer Kathrin , Raasch Markus 
Published: January 2023

Zusammenfassung
Die Bedeutung von Religiosität im Alltag christlicher Familien während des Zweiten Weltkrieges wurde bislang noch nicht eingehend untersucht. Der Beitrag macht einen Aufschlag und untersucht anhand von Feldpostbriefen und Zeitzeug:innenbefragungen, inwiefern ein religiöses Familienleben mit den Ansprüchen der „kriegerischen Volksgemeinschaft“ (Dietmar Süß) überhaupt vereinbar war. Deutlich wird bei allen notwendigen Differenzierungen, dass Religiosität einen wichtigen Resilienzfaktor in Krisenzeiten bilden und wesentlich dazu beitragen konnte, die Realität des Krieges mitsamt seinen weitreichenden Auswirkungen zu bewältigen.
Der Ukrainekrieg als Nagelprobe einer christlichen Friedenserziehung: Konzeptionelle Reflexionen und konkrete Handlungsperspektiven für den Religionsunterricht
Authors: Herbst Jan-Hendrik 
Published: January 2023

Zusammenfassung
Der Ukrainekrieg fordert grundlegende Annahmen christlicher Friedensethik und -erziehung heraus. Vor diesem Hintergrund legt der Artikel drei Erkenntnisse der Friedenspädagogik frei, hinter die heute nicht mehr zurückgefallen werden darf: Religionen besitzen eine ambivalente Rolle in politischen Konflikten; entwicklungsabhängig sind individuelle und strukturelle Aspekte von Krieg und Frieden zusammen zu denken; und eine ‚pazifistische Positionalität‘ ist heute im Religionsunterricht kontrovers zu diskutieren. An diese konzeptionellen Reflexionen anschließend werden konkrete Handlungsperspektiven für den Unterricht entfaltet und exemplarisch anhand von drei Großmethoden diskutiert: Friedensgebete, Planspiele und sozialpolitische Aktionen.
Kinase inhibitors in thyroid cancers
Authors: Sukrithan Vineeth , Jain Prachi , Shah Manisha H , Konda Bhavana 
Published: January 2023

Objective
The treatment landscape for thyroid cancers has changed rapidly with the availability of kinase inhibitors against VEGFR, BRAF, MEK, NTRK, and RET. We provide an up-to-date review of the role of kinase inhibitors in thyroid cancer and discuss upcoming trials.

Design & Methods
A comprehensive review of the available literature describing kinase inhibitors in thyroid cancer was performed.

Results and Conclusions
Kinase inhibitors have become the standard of care for patients with metastatic radioactive iodine-refractory thyroid cancer. Short-term treatment can re-sensitize differentiated thyroid cancer to radioactive iodine, thereby potentially improving outcomes and sparing toxicities associated with the long-term use of kinase inhibitors. The approval of cabozantinib as salvage therapy for progressive radioactive iodine-refractory differentiated thyroid cancer following failure with sorafenib or lenvatinib adds to the available armamentarium of active agents. Vandetanib and cabozantinib have become mainstay treatments for metastatic medullary thyroid cancer regardless of RET mutation status. Selpercatinib and pralsetinib, potent and selective receptor kinase inhibitors with activity against RET, have revolutionized the treatment paradigm for medullary thyroid cancers and other cancers with driver mutations in RET. Dabrafenib plus trametinib for BRAF mutated anaplastic thyroid cancer provides an effective treatment option for this aggressive cancer with a dismal prognosis. In order to design the next generation of agents for thyroid cancer, future efforts will need to focus on developing a better understanding of the mechanisms of resistance to kinase inhibition including bypass signaling and escape mutations.
Addressing Problems in Reporting and Classification of Complications in Neurosurgery
Authors: Riabec Pavel , Šustickas Gytis 
Published: January 2023

Objective. The purpose of this study was to quantify the rate of adverse events associated to in neurosurgery interventions, to evaluate the differences in reporting of such events among different authors and reviews, and to find the reason behind the occurrence of this differences. Methods. A systematic literature review of scientific publications on existing classifications and reports of frequency on complications in neurosurgery was performed by analysing articles from international databases. Results and conclusion. This current overview is taking an outlook on the existing issues in the classification and reporting of complications in neurosurgery. Complications are common in neurosurgery. Because of nonuniform criteria, unstandardized data gathering procedures, and retrospective data collection, their reporting is inconsistent and varies considerably among authors and reviews. The best way to address this issue is by gathering prospective, multi-institutional outcomes data on neurosurgical patients. The data collection initiatives in the future should be using same terminology and be based on the same universally accepted criteria.

Published: January 2023

Aim. This study evaluated the survival of gastric cancer patients with metastasis to the hepatoduodenal, retropancreatic, mesenteric, and para-aortic lymph nodes. Materials and methods. We analyzed the survival rate of 435 gastric cancer patients who underwent operation from 2001 to 2010 at the Department of Surgery, Chonnam National University Hospital. There were 43, 25, 16, and 55 patients with metastasis to the hepatoduodenal, retropancreatic, mesenteric, and para-aortic nodes, respectively. Results. Based on tumor location, metastasis to the para-aortic lymph nodes was more common in upper-third cancer, and that to the hepatoduodenal lymph nodes was more common in lower-third cancer. The survival rate of patients with non-regional lymph node metastasis was better than that of patients with hepatic metastasis or peritoneal dissemination (p < 0.05). Conclusion. We recommend performing a more extended lymphadenectomy than a D2 lymphadenectomy in patients with advanced gastric cancer those having metastasis to the hepatoduodenal nodes.
Changing Tendencies of Patients with Electrical Burns in Lithuania from 2016 to 2020
Authors: Sipavičius Viljamas , Rimdeika Rytis 
Published: January 2023

Background. Electrical injuries are not common, however these injuries are severe. The burns cause damage for both superficial and deep layers of skin, as well as deeper tissues, and can lead to necrosis. Morbidity and mortality from electrical injuries are quite high and have physical and psychological consequences. Epidemiological analysis of electrical burns helps to understand patterns of these devastating injuries and to plan further treatment strategies. The objective of the study is to evaluate the number of patients affected by electrical injuries in Lithuania from 2016 to 2020. Methods. Data for the study were used from the Health Information Center of the Institute of Hygiene, calculated from the information system SVEIDRA of the State Health Insurance Fund under the Ministry of Health of Lithuania. Statistical analysis of the data was performed using IBM SPSS statistics 23.0 software. Using the Mann-Whitney criterion, a comparison was made between the percentage distributions of electrical injuries during the study period. Results. During five years (2016–2020), 355 peop­le in total, 85 of them children, were affected by electrical injuries. Men were more likely to suffer from electric injuries. 80.4 percent males were affected and 19.6 percent females. Overall, electrical injuries decreased by 8.45 percent. The number of electrical injuries decreased by 3.66% in the children group and 4.79% in the adult group. Conclusions. After reviewing the research data, it can be concluded that from 2016 to 2020, there was decreased tendency of electrical injuries in Lithuania by 15.3% among children and by 6.29% among adults. Men were more likely to experience electrical injuries. Ongoing prevention strategies and measures in society and raising social awareness are key factors in reducing electrical injuries.

Published: January 2023

Surgical procedures in highly vascularized renal parenchyma sometimes can cause iatrogenic vascular complications. Although incidence renal pseudoaneurysms after partial nephrectomy is low, around 1%, clinical presentation of these patients can be quite severe – hematuria, lumbar pain, dizziness, weakness. Prompt and precise diagnostics and treatment are essential. Ultrasound and Computed Tomography are two most common diagnostic approaches for the assessment of pseudoaneurysms or arteriovenous fistulas following partial nephrectomy. Endovascular selective microcoil embolization is a safe and effective kidney-preserving procedure for treating iatrogenic vascular complications. Although when embolizing renal arteries some of renal parenchyma loses perfusion and becomes fibrotic, no significant decrease in renal function in early post-embolization period was noted. Comparing open surgery to endovascular treatment of pseudoaneurysms, latter one allows shorter average hospital stay and less frequent cardiac and peripheral vascular complications. The article discusses a case of a patient that had developed renal pseudoaneurysm after partial nephrectomy. During a routine check-up of a middle-aged woman a presumable renal cyst was found. On more throughout examination the cyst was ruled as a tumour and partial nephrectomy was performed. After 12 days from surgery patient was admitted to hospital complaining macrohematuria, lower abdomen pain, episodic right-side ache. Urgent contrast enhanced computed tomography was performed, which confirmed that patient was bleeding from the operated kidney. Patient was admitted to interventional radiology departament and perform embolization of bleeding vessel. After embolization of pseudoaneurysm, bleeding was controlled and patient was completely treated.
Surgical Treatment of Siewert II Gastroesophagel Junction Adenocarcinoma: Esophagectomy or Gastrectomy? Review
Authors: Imbrasaitė Ugnė , Giršvildaitė Dovilė , Baušys Rimantas , Baušys Augustinas 
Published: January 2023

Introduction. Surgery is the only curative treatment option for patients with gastroesophageal junction (GEJ) adenocarcinoma. These tumors can be resected by gastrectomy or esophagectomy depending on tumor localization. Although, both surgeries are available for Siewert type II GEJ cancer, it remains unknown which one is superior. This review summarizes current evidences on the optimal surgical approach for Siewert type II GEJ adenocarcinoma. Methods. The literature search was performed within the PubMed database and 9 stu­dies comparing gastrectomy and esophagectomy for Siewert type II GEJ adenocarcinoma were included. The outcomes of interest included: length of surgery, numbers of retrieved lymph nodes, resection margins, postoperative morbidity and mortality, hospitalization time, 5-year overall, and disease-free survival rates. Results. Current studies do not favor any type of surgery in terms of length of the surgery, R0 resection rate, or postoperative morbidity. There is some tendency towards higher anastomotic leakage and postoperative surgical site infections rate after gastrectomy, while a higher incidence of pneumonia after esophagectomy. Similar, available studies suggest, that esophagectomy may lead to improved long-term outcomes. Conclusions. There is a lack of high-quality studies comparing gastrectomy and esophagectomy for Siewert type II GEJ adenocarcinoma. Esophagectomy may lead to improved long-term outcomes, but this preliminary data has to be confirmed in large, randomized control trials.
How do TV and radio hosts speak? Vowel tenseness as an index of formal and serious speaking style
Authors: Čičirkaitė Ramune 
Published: January 2023

The present paper reports the instrumental analysis of the unstressed variants of /iː/, /uː/, /eː/, /oː/, /æː/ and /ɑː/. The study was carried out by employing the sound analysis software PRAAT, which was used to measure the length and tenseness of the specified variants. 10 residents of Vilnius city and 10 hosts of TV/radio programmes covering serious public topics were selected as the informants of the study. The main aims of this research were as follows: (1) to determine whether vowel length and tenseness differentiate the pronunciation of Vilnius city residents from that of the hosts of TV/radio programmes covering serious public topics, and (2) to reveal whether the hosts of TV/radio programmes use the length or tenseness of the unstressed variants of /iː/, /uː/, /eː/, /oː/, /æː/, /ɑː/ as a resource for creating a formal and serious speaking style. The current study examines, among other things, if the TV/radio hosts pronounce the unstressed variants of /iː/, /uː/, /eː/, /oː/, /æː/, /ɑː/ systematically more tensely, or perhaps on the contrary – they create the impression of a serious style only with isolated sounds of increased tenseness. The analysis has revealed that the hosts of TV/radio programmes covering serious topics pronounce the unstressed variants of /iː/, /uː/, /eː/, /oː/, /æː/ and /ɑː/ in the same length as Vilnius city residents speaking in a semi-formal style. Hence, vowel length in the said programmes is not a significant linguistic resource when creating a serious and formal speaking style and constructing the linguistic identity of a TV/radio host addressing serious public topics. However, TV/radio hosts covering serious public topics pronounce the unstressed variants of /iː/, /uː/, /eː/, /oː/, /æː/ and /ɑː/ with more tenseness than Vilnius city residents, which suggests that the style of the hosts is distinct from the semi-formal speaking style of Vilnius city residents and serves as a well-defined marker of a certain language standard. These findings are in line with some previous studies indicating that vowel tenseness statistically significantly distinguishes programmes covering serious public topics from entertainment-based programmes covering personal topics. Therefore, it can be argued that vowel tenseness differentiates speakers (TV/radio hosts vs. Vilnius city residents), types of programmes (programmes covering serious public topics vs. entertainment-based programmes covering personal topics), styles (formal vs. semi-formal), and language varieties (actual standard language vs. Vilnius speech). Thus, in the speech of hosts of TV/radio programmes covering serious public topics, tenseness acquires the indexical meaning of “I am speaking seriously”. The use of isolated vowels of increased tenseness is thus sufficient to create the impression of a serious speaking style and to form the linguistic identity of a TV/radio host covering serious topics.
