Qualitative Investigation of Wake Composition in Offshore Wind Turbines: A Combined Computational and Statistical Analysis of Inner and Outer Blade Sections
Authors: Siddiqui M. Salman , Badar Abdul Waheed , Yang Liang , Saeed Muhammed , Keprate Arvind
Published: February 2024

High-fidelity numerical simulations are used to thoroughly analyze the evolution of the wake behind a megawatt-scale offshore wind turbine. The wake features are classified in terms of wake dynamics composition and the associated turbulence characteristics originating from the inner and outer sections of the blades. Understanding the wake is essential for developing compact layouts for future wind farms. We employed a transient Sliding Mesh Interface (SMI) technique to analyze the fully dynamic wake evolution of the offshore NREL 5MW full turbine. Our high-fidelity results have been validated against previously published results in the literature. We thoroughly investigated the dominant structures of the wake using Proper Orthogonal Decomposition (POD) techniques, which we applied to transient simulations of fully developed flows after five wind turbine revolutions over the snapshot data. Our findings show that the inner section of the blades, which is composed of airfoils with larger cross-sections, is responsible for the dominant components of the wake, while the contribution of the wake from the outer section of the blade is significantly lower. Therefore, designing more aerodynamic sections for the blade’s inner section can help reduce the dominant wake components and thus decrease the inter-turbine distance in future wind farms.

Published: February 2024

The integration of photovoltaic (PV) system in power system proved to be potential technology in terms of renewable energy sources. However, photovoltaic system has major drawback of rise in cell temperature, which results in low power production and reduced service life. To overcome the temperature rise in photovoltaic system, the addition of water cooling and phase change materials installed at rear side PV system termed as photovoltaic thermal (PVT) system has been adopted in this study. The organic phase change material (RT-42) having melting temperature of 42 ℃ and water cooling running at 0.45 litre per minute (LPM) under 440 W/m2 irradiation has been taken as input parameters. The photovoltaic system and water cooled photovoltaic system performance has been analysed by using real time solar simulator. Additionally, the PVT-PCM system is assessed by use of TRNSYS simulation. Finally, this study compares the thermal and electrical efficiency of PV, PVT, and PVT-PCM systems. The findings indicated that maximum temperature for PV cells in a PV system was 59 ℃. Water cooling alone reduces the temperature down to 49 ℃, whereas water cooling combined with phase change material (PVT-PCM) lowers it down to 36℃. Further, the heat gain of 189 watt and 191 watt was achieved for PVT and PVT-PCM system. Additionally, the PV, PVT, and PVT-PCM systems achieved electrical efficiencies of 6.1%, 7%, and 9.5%, correspondingly.

Published: February 2024

Solar energy is becoming an increasingly popular and important source of renewable energy. Solar trees have emerged as a novel and innovative approach to harvesting solar energy. Solar trees are artificial structures that mimic the shape and function of trees, with branches or leaves that contain photovoltaic cells to convert sunlight into electricity. The solar tree generates both electrical and thermal energy from solar radiation. The present study tested the thermal (module temperature, heat loss coefficient), electrical (power output), and operating parameters of a solar tree at Universiti Malaysia Pahang, Pekan, Malaysia, on a typical sunny day. First-law analysis and second-law analysis were carried out to determine exergy losses during the photovoltaic conversion process of solar trees. The data obtained from the experiment is utilized to determine the energy and exergy efficiencies of the solar tree. The energy efficiency ranges from 16.8% to 8.3% throughout the day, displaying some variability. However, as for the exergy efficiency of the photovoltaic solar tree under consideration, it is observed to be lower, ranging from 16.1% to 6.6% for electricity generation. It is observed that the exergy losses increased with increasing module temperature and a drop in exergy efficiency.
Photocatalytic evaluation of chitosan and its derivative coated vanadium pentoxide nanoparticles for photodegradation of methylene blue
Authors: Bansal Smriti , Jain Purnima
Published: February 2024

Vanadium pentoxide (V2O5) is widely utilized as a photocatalyst for the degradation of various pollutants due to its narrow bandgap and convertible oxidation states of vanadium. Here, V2O5 nano-adsorbents coated with functionalized chitosan exhibit a great sensitivity to the absorption of visible light that makes them a suitable candidate to study the photodegradation of methylene blue in the natural atmosphere. Characterization results revealed the synthesis of chitosan-anisaldehyde Schiff base and its presence over the surface of nanoparticles. Fabricated nanoparticles exhibited enhanced optical band gap that increases the photodegradation efficiency by reducing the recombination rate as well as they possess an orthorhombic crystalline phase as confirmed by XRD. Among all fabricated nanoparticles, one of the coated nano-adsorbents, chitosan-anisaldehyde adorned V2O5 (CHA1), having wedge-shaped pores that aided in the photocatalytic destruction of methylene blue illustrates the best degradation efficiency as compared to the bare ones.
Relative Comparison of Adsorption and Corrosion Inhibition Studies of Expired Vitamin B12 and C Over Mild Steel in 0.5 M H2SO4
Authors: Sheetal  , Thakur Sanjeeve , Kumar Singh Ashish
Published: February 2024

In comparison to organic corrosion inhibitors, green corrosion inhibitors are in great need for mitigating corrosion of metals and alloys ascribed to their benign toxicity in addition to absence of heavy metals and toxic substances. Contemporary research conducted in this field is more focused on implementing an efficient approach towards corrosion mitigation. The present work highlights the evaluation of anti-corrosive potential of expired Vitamin B and Vitamin C over mild steel in 0.5M H2SO4. Gravimetric and electrochemical studies have been utilized as affirmatory tool for corrosion retarding ability of the synthesized derivative. Concentration increase brought a profound rise in corrosion inhibition efficiency whereas variation in temperature from 308 K-328 K retarded the protection ability of respective inhibitors whereas electrochemical studies presented depressed semi-circles in Nyquist plots and potentiodynamic values demarcated both inhibitors as mixed type. Furthermore, a comparison among the two tested vitamins has been drawn. Contact angle measurements have been involved here to confirm the inhibitors adsorption over mild steel surface. The present experimental work will provide future insights for researchers working in field of corrosion.
Manufacturing Sectors’ Adoption of Sustainable Energy Technologies: Towards Advance Rate of Implementation
Authors: Gutierrez Ma. Teodora , Ermita Philip
Published: February 2024

The paper aims to assess the knowledge, capacity, skills, and goals of different sectors regarding sustainable energy technology. It used semi-structured and open-ended questions to let respondents share their knowledge, information, and attitudes more freely about the extent of using sustainable energies in their companies. The respondents were business owners, managers, and specialists from various industries. All agreed that sustainable energy technologies provide benefits for their businesses, but most said that they are difficult to implement due to a lack of finance in this aspect, a lack of experience, a lack of awareness, and a lack of infrastructure. Most respondents are willing to accept their responsibilities for implementing sustainable energy in their operations. Respondents from small business companies are not aware of this concept of sustainable energy, but they use solar panel technology in their company because they know it will reduce their electricity costs. However, respondents from large enterprises have more knowledge of the concept of sustainable energy. Currently, they only use solar panels as a sustainable energy technology in some areas of their operation. Limited financial resources for this and their expertise are obstacles to expanding the use of sustainable energies in their company.

Impact of Incorporating Rice Husk Ash (RHA) into Recycled Concrete Aggregates (RCA) on the Compressive and Flexural Strength of Concrete
Authors: Adier Maria Fe , Silva Dante
Published: February 2024

This study aimed to assess the strength characteristics of concrete using Recycled Concrete Aggregates (RCA) as full replacement to coarse aggregates and Rice Husk Ash (RHA) as an admixture. The concrete samples were subjected to curing for 7, 14, and 28 days. Specifically, the study evaluated the workability of freshly mixed concrete and compared the compressive and flexural strength with RCA and RHA to normal concrete. Four different treatment mixtures were used with three replicates with varying ratio of RHA to cement: Treatment 1 (1 cement: ¾ RHA), Treatment 2 (1 cement: ½ RHA), Treatment 3 (1 cement: ¼ RHA). In all cases, RCA completely replaced natural coarse aggregates. The results indicated that the slump which measures the workability of the RCA concrete met the desired standard specifications. Additionally, the RCA concrete with the highest RHA content obtained the highest compressive and flexural strength on the 28th day test but did not exceed the control. Furthermore, the study revealed that the concrete specimens could handle maximum loads for flexure rather than compression load.
A multi-variable service supply management portfolio model for Telecom industry
Authors: Bamdadsoofi Jahanyar , Seddighi Fahimeh , Mohammadnezhad Chari Fatemeh
Published: February 2024

Supply operations require some kind of classification according to the features of items. Based on the literature review and expert interview, a multi-variable service supply management portfolio model was developed to classify the procurable service items in the Telecom industry in a more realistic way with better precision. First, a multi-level relational reflective model was built based on four dimensions using the fuzzy Delphi method and the model was validated by factor analysis. Then, 50 service items were placed in 16 clusters of the portfolio model. For each category of services in the model, the pertinent supplier relationship management practices were proposed using the literature review accompanied by a focus group. The presented model contributed to the development of previous theoretical trends in supply management portfolio models by introducing a new dimension, called “pace of innovation in technology”, to those extracted from the literature review, such as “strategic importance of the items”, “supply risk”, and “extent of buyer captivity”. Despite the classical models targeting tangible goods and products, our model was customized for the service industry context and can be considered a starting point towards service supply market segmentation procedures according to the attributes of each service item category.

Published: February 2024

This paper presents a novel approach to portfolio optimization in the field of finance, with a specific focus on short-term yield. Existing literature has mainly utilized fundamental data to predict long-term trends in stock prices, but our proposed methodology utilizes technical indicators based on the theory of chasing up. Furthermore, we address the non-cooperative nature of volume and price fluctuation indicators and introduce non-cooperative theory into the short-term volume and price stock selection scheme for the first time. We propose an optimization of short-term stock selection based on volume and price using a non-cooperative parallel Data Envelopment Analysis (DEA) model, which we apply to Chinese main board listed companies. Our empirical results demonstrate the effectiveness of our model in selecting high-yield stocks in the short term. This paper contributes to the ongoing discussion on portfolio optimization and presents a compelling solution for investors seeking to maximize their financial gains. The proposed methodology can be utilized in practical applications and has significant implications for the financial industry.

Steroid-Sensitive Nephrotic Syndrome in Children, Multicentric
Study
Authors: Konopásek Patrik , Skálová Sylva , Sládková Eva , Pecková Monika , Flachsová Eva , Urbanová Ivana , Laubová Jana , Samešová Martina , Dvořák Pavel , Zieg Jakub
Published: February 2024

Background Several previous studies have reported a more severe course of
nephrotic syndrome in children with low birth weight.

Patients Cohort of 223 children with idiopathic nephrotic syndrome.

Methods We aimed to investigate the association between course of
nephrotic syndrome and low birth weight. Data from seven paediatric nephrology
centres were used.

Results Children with low birth weight had 3.84 times higher odds for a
more severe course of steroid-sensitive nephrotic syndrome (95% CI
1.20–17.22, P=0.041), and those with low birth weight and
remission after 7 days had much higher odds for a more severe course of disease
(OR 8.7). Low birth weight children had a longer time to remission (median 12
vs. 10 days, P=0.03). They had a higher need for steroid-sparing agents
(OR for the same sex=3.26 [95% CI 1.17–11.62,
P=0.039]), and the odds were even higher in females with low birth
weight (OR 6.81). There was no evidence of an association either between low
birth weight and focal segmental glomerulosclerosis or between low birth weight
and steroid-resistant nephrotic syndrome.

Discussion We conducted the first multicentric study confirming the worse
outcomes of children with NS and LBW and we found additional risk factors.

Conclusions Low birth weight is associated with a more severe course of
steroid-sensitive nephrotic syndrome, while being female and achieving remission
after 7 days are additional risk factors.
Oral Anticoagulation and Mortality in Cases with Intracranial Bleeding: Analysis of Nationwide Prescription and Hospitalization Data
Authors: Kröger Knut , Heldt Fabian , Feyen Ludger , Feller Kathrin , Kowall Bernd , Stang Andreas
Published: February 2024

Objectives To demonstrate the safety of direct oral anticoagulants in relation to intracranial bleeding (ICB), we compared the number of patients taking anticoagulants in all cases of hospitalization and cases of hospitalization for ICB over time in Germany. We analyzed the intrahospital mortality of ICB cases in relation to long-term use of anticoagulants (LUAs).

We performed a retrospective registry analysis of nationwide German hospitalizations including all hospital admissions and admission for ICB in patients aged ≥60 years in the period from 2006 to 2020 and separated for LUAs.

Results In 2006, the age-standardized rate of hospitalized male patients with LUAs was 7.3% and that of female patients was 5.6%. In 2020, the rates increased to 22.0 and 17.7% for male and female patients, respectively. Among patients hospitalized for ICB in 2006, 7.0 and 5.6% were male and female patients with LUAs, respectively. In 2020, the rate increased to 13.7% for males and 10.8% for females.

In 2006, age-standardized mortality rates of male and female patients with ICB without LUAs were 24.1 and 23.9%, respectively. In 2020, the rate slightly decreased to 22.7% in males, but it remained almost unchanged in females at 23.8%. In the cases with LUA, the mortality rate decreased from 30.1 to 24.3% in males and from 28.4 to 24.2% in females in the same period.

Conclusion LUA seems to be safe because there is a slower increase of the rate of LUAs in ICB cases than in generally hospitalized cases in the period from 2006 to 2020. In addition, mortality in ICB cases with LUA tends to decrease compared to cases without LUA.
Rezidiv eines Desmoidtumors in einer Narbe an der Entnahmestelle
eines Latissimus-dorsi-Lappens
Authors: Abdu Hazem , Cedidi Can
Published: February 2024

Der Desmoidtumor, auch bekannt als aggressiver fibröser Tumor oder
Desmoid-Fibromatose, ist ein seltener, gutartiger Tumor, der aus
Bindegewebszellen entsteht. Desmoidtumoren machen etwa 0,03+%
aller Neoplasien und weniger als 3+% aller Weichteiltumoren aus.
Die geschätzte Inzidenz in der Allgemeinbevölkerung
beträgt 2 bis 4 Fälle pro Million Einwohner pro Jahr [1]. Der
Desmoidtumor zeichnet sich durch sein aggressives Wachstum aus, metastasiert
jedoch in der Regel nicht. Er tritt häufig bei jungen Erwachsenen auf
und betrifft bevorzugt bestimmte Körperregionen wie den Bauch, die
Schulter, den Brustkorb oder die Extremitäten. Die genaue Ursache der
Erkrankung ist noch nicht vollständig geklärt, aber genetische
Veränderungen und hormonelle Faktoren könnten eine Rolle
spielen. Die Symptome eines Desmoidtumors hängen von seiner Lage und
Größe ab. Häufig treten Schmerzen, Schwellungen oder
Bewegungseinschränkungen auf. Die Diagnose erfolgt in der Regel durch
eine Gewebeprobe (Biopsie) und bildgebende Verfahren wie MRT oder CT [2]. Unser
vorliegender Fall stellt nach unserem Kenntnisstand den ersten dokumentierten
Fall eines Rezidivs eines Desmoidtumors in der Narbe an der Entnahmestelle des
Latissimus-dorsi- Lappens dar, welcher zuvor zur Rekonstruktion einer
Desmoidresektion am Unterschenkel verwendet wurde.

Published: February 2024

Background With the widespread use of direct oral anticoagulants (DOACs), there is an urgent need for a rapid assay to exclude clinically relevant plasma levels. Accurate and rapid determination of DOAC levels would guide medical decision-making to (1) determine the potential contribution of the DOAC to spontaneous or trauma-induced hemorrhage; (2) identify appropriate candidates for reversal, or (3) optimize the timing of urgent surgery or intervention.

Methods and Results The DOAC Dipstick test uses a disposable strip to identify factor Xa- or thrombin inhibitors in a urine sample. Based on the results of a systematic literature search followed by an analysis of a simple pooling of five retrieved clinical studies, the test strip has a high sensitivity and an acceptably high negative predictive value when compared with levels measured with liquid chromatography tandem mass spectrometry or calibrated chromogenic assays to reliably exclude plasma DOAC concentrations ≥30 ng/mL.

Conclusion Based on these data, a simple algorithm is proposed to enhance medical decision-making in acute care indications useful primarily in hospitals not having readily available quantitative tests and 24/7. This algorithm not only determines DOAC exposure but also differentiates between factor Xa and thrombin inhibitors to better guide clinical management.

Published: February 2024

Background and study aims In cases of inaccessible papilla, EUS-guided biliary drainage (EUS-BD) has been described as an alternative to calibrate benign biliary stenosis. However, few studies are available.

Patients and methods This tw-center, retrospective study was designed to evaluate technical success and clinical success at 1 year. All patients who underswent EUS-BD without the rendezvous technique used for calibration of benign biliary stenosis were included from 2016 to 2022. Patients underwent EUS-hepaticogastrostomy (EUS-HGS) during the first session. Then, HGS was used to access the bile duct, allowing calibration of the stenosis: Dilation of the biliary stenosis and placement of double pigtail stents through the stenosis for 1 year.

Results Thirty-six patients were included. Technical success was 89% (32/36), with four failures to cross the stenosis but EUS-HGS was performed in 100% of the cases. Nine patients were excluded during calibration because of oncological relapse in six and complex stenosis in three. Three patients had not yet reached 1 year of follow-up. Twenty patients had a calibration for at least 1 year. Clinical success after stent placement was considered in all cases after 1 year of follow-up. Thirteen patients underwent stent removal and no relapse occurred after 435 days of follow-up (SD=568). Global morbidity was 41.7% (15/36) with only one serious complication (needing intensive care), including seven cases of cholangitis due to intrabiliary duct obstruction and five stent migrations. No deaths were reported.

Conclusions EUS-BD for calibration in case of benign biliary stenosis is an option. Dedicated materials are needed to decrease morbidity.

Introduction Wegener granulomatosis (WG) appears with clinical symptoms, including recurrent respiratory infection, renal manifestations, and nonspecific systemic symptoms.

Objective To study the clinical manifestations of WG in Iranian ethnicities, and data on 164 patients were recorded from 2013 to 2018.

Methods The data included demographics, symptoms, and the Birmingham Vasculitis Activity Score (BVAS). The symptoms involved the following sites: the nose, sinus, glottis, ears, lungs, kidneys, eyes, central nervous system, mucous membranes, skin, heart, stomach, intestine, as well as general symptoms. The clinical manifestations of nine ethnicities were analyzed.

Results In total, 48% of the patients were male and 51% were female, with a median age of 51 years. The BVAS was of 15.4, the sites most involved were the sinus (n = 155), nose (n = 126), lungs (n = 125), and ears (n = 107). Gastrointestinal (n = 14) and cardiac (n = 7) involvement were less common. Among the patients, 48.17% were Persian, 13.41% were Azari, 11.17% were Gilaki, 11.17% were Kurd, and 10.9% were Lor.

Conclusion Our findings indicated that the sinus, nose, lungs, and ears were the sites most involved, and gastrointestinal and cardiac involvement were less common. In the present study, involvement of the upper and lower respiratory tract was higher than that reported in Western and Asian case series. Moreover, we report for the first time that, in all patients with ear involvement, the left ear was the first to be affected. The clinical manifestations among Iranian ethnicities were not different, and the Gilaki ethnicity had the highest BVAS, mostly because the weather was humid; therefore, in Iran, in areas with humidity, the rate of the disease was higher.

Introduction Lips play a fundamental role in facial attractiveness and in decisions pertaining to orthognathic surgery.

Objective To assess the upper lip changes following Le Fort I osteotomy for maxillary advancement and/or impaction.

Methods In the present retrospective non-randomized clinical trial, we evaluated 3 groups of patients who underwent Le Fort I osteotomy of the maxilla. Group 1 (n = 35) underwent maxillary advancement, group 2 (n = 14), maxillary impaction, and group 3 (n = 11) was submitted to both maxillary advancement and impaction. The lip thickness of all patients was measured preoperatively, and the participants in each group were categorized into two subgroups: thin (< 12 mm) and thick (> 12 mm) lip. The primary (before orthognathic surgery) and final (after orthodontic bracket removal) lateral cephalograms of the patients were analyzed using the Dolphin software. Comparisons were made using the paired t-test and linear regression in the IBM SPSS Statistics for Windows software.

Results The length of the upper lip increased by 1 mm (p = 0.012) on average following maxillary advancement, and it decreased by 0.43 mm (p = 0.24) on average following maxillary impaction. In the maxillary advancement group, the change in angulation of the incisors predicted the incisal display (p = 0.03). In the maxillary impaction group, skeletal changes in the vertical dimension predicted changes in upper lip length (p = 0.033).

Conclusions Le Fort I osteotomy for maxillary advancement significantly increases the length of the upper lip. The assessment of lip thickness prior to surgery can help predict the postoperative results. Changing the angulation of the incisors can predict the incisal display. In maxillary impaction, skeletal changes in the vertical dimension can predict the changes in the length of the upper lip.

Published: February 2024

Introduction The most common postoperative complication of total thyroidectomy is hypocalcemia, usually monitored using serum parathyroid hormone and calcium values.

Objective To identify the most accurate predictors of hypocalcemia, construct a risk assesment algorithm and analyze the impact of using several calcium correction formulas in practice.

Methods A prospective, single-center, non-randomized longitudinal cohort study on 205 patients undergoing total thyroidectomy. Parathyroid hormone, serum, and ionized calcium were sampled post-surgery, with the presence of symptomatic or laboratory-verified asymptomatic hypocalcemia designated as primary outcome measures.

Results Parathyroid hormone sampled on the first postoperative day was the most sensitive predictor of symptomatic hypocalcemia development (sensitivity 80.22%, cut-off value ≤2.03 pmol/L). A combination of serum calcium and parathyroid concentration sampled on the first postoperative day predicted the development of hypocalcemia during recovery with the highest sensitivity and specificity (94% sensitivity, cut-off ≤2.1 mmol/L, and 89% specificity, cut-off ≤1.55 pmol/L, respectively). The use of algorithms and correction formulas did not improve the accuracy of predicting symptomatic or asymptomatic hypocalcemia.

Conclusions The most sensitive predictor of symptomatic hypocalcemia present on the fifth postoperative day was PTH sampled on the first postoperative day. The need for algorithms and correction formulas is limited.

In 1964, the Section of Plastic and Reconstructive Surgery at the University of Michigan opened its doors to future surgeons and leaders in the field. Today, we are celebrating the 60-year history of the program and its significant contributions to the field. Beginning under the leadership of Reed O. Dingman, MD, DDS, the program began with three faculty members and two independent surgical residents. Since that time, it has expanded dramatically to include 24 faculty members and 28 integrated plastic surgery residents. The goals of the program have always been to achieve excellence in all three of our academic missions including clinical care, teaching, and research. Annually, the program sees an average of 35,000 outpatient clinic visits, 4,000 major operations, 200 peer-reviewed publications, $5,000,000 in research spending, and residents who are well trained and highly competitive for fellowships of their choosing every single year. Through scientific collaborations, academic exchanges, and medical missions, the program's influence has spread beyond Michigan, reaching the entire world. In addition to training world-renowned surgeons, Michigan's faculty and graduates have assumed leadership roles in prestigious professional organizations, scientific journals, and research foundations. In this article, we explore the roots of the program and reflect on six decades of impact, innovation, and inspiration.

Published: February 2024

Objective To describe our technique and share our experience with image-guided transrectal drainage (TRD) of pelvic abscesses in children.

Materials and Methods Retrospective review and analysis of indications for image-guided TRD and examination of procedural outcomes in pediatric patients with pelvic abscesses over 8 years.

Results A total of 69 patients (33 males and 36 females) with symptomatic pelvic abscesses underwent image-guided TRD. The median age and weight of the patients were 11.5 years (range, 3–18) and 46.8 kg (range, 15.1–118.0), respectively. The etiologies of the pelvic abscesses were perforated appendicitis (72.5%) and post-operative collections (27.5%). All patients presented with abdominal pain. Fever, emesis, and diarrhea were also common symptoms. The size of the pelvic abscesses ranged from 24.0 to 937.1 mL (median, 132.7). Technical success was achieved in 68 of 69 TRD procedures (98.6%). Clinical improvement was observed in all patients with technically successful TRD. The TRD catheter dwell time ranged from 0 to 10 days (median, 4.0). Most patients who underwent TRD for perforated appendicitis subsequently underwent elective appendectomy after the resolution of the pelvic abscess (84.0%). The median time from TRD to elective appendectomy was 2.8 months (range, 0.3–6.1). There were no procedure-related complications.

Conclusion Image-guided TRD is a safe and effective procedure with high technical and clinical success rates for the treatment of pelvic abscesses in children.

Published: February 2024

Background and Objectives Surgery to masculinize the chest is a frequently sought-after procedure by transmen who wish to conform their physical appearance to their gender identity. In our study, the outcomes of surgical masculinization comprising subcutaneous mastectomy through a modified elliptical incision, liposuction, reduced inert nipple–areola grafting, and quilting stitches were analyzed.

Materials and Methods Thirty-two transmen with large breasts and hypertrophied nipples and areolae underwent the above-mentioned masculinizing procedure in this prospective cohort study. Our statistically validated institutional aesthetic outcome assessment score (IAOAS) was used to analyze the outcomes at the end of the follow-up period.

Results The average period of follow-up was 24.5 months. The average final IAOAS was 23.1. The rate of complications was found to be associated with using breast binders. In all, 22 of 32 patients (68.75%) had an excellent outcome score, while 10 patients (31.25%) had a good outcome score (p = 0.025).

Conclusion Top surgery is crucial for transmasculine patients to achieve their desired gender identity as males. It is imperative that this procedure is performed to their complete satisfaction. Our single-staged comprehensive approach of subcutaneous mastectomy and liposuction with reduced inert nipple and areola grafts, which aids in a swift transition to a male role, is a prerequisite for bottom surgery at our institute.
TV simultaneous interpreting of proper nouns from English to Arabic in King Charles III’s speeches

This paper aims to explore the interpreting strategies which were employed by TV interpreters to render English proper nouns (PNs) into Arabic. The data of the study comprise PNs detected in King Charles III’s political speeches along with their Arabic renditions produced live by three TV interpreters working for Al Jazeera, Sky News Arabic, and France 24. The study embarks on a qualitative and quantitative approach to achieve its aim. Based on the classification of PNs carried out by Särkkä (2007), PNs found in the English speeches are categorized in terms of their internal syntactic structure into central PNs (CPNs), extended PNs (EPNs), and descriptive PNs (DPNs). The Arabic renditions of PNs are analysed aiming to find a correlation between the category of the proper noun (PN) and the employed strategy. Based on Kalina’s (1992) typology of interpreting strategies, the results indicate that TV interpreters in many cases resorted to emergency strategies, such as omission and compression, to deal with different categories of PNs. The former strategy is particularly evident in dealing with CPNs while the latter appears mostly in DPNs. Aside from emergency strategies, transliteration is frequently used by TV interpreters to render CPNs while the strategy of transliteration plus translation is dominant in rendering EPNs.
