The Effect of Shear Span on the Behavior of Triangularly Corrugated Web Steel Girders
Authors: Abdullah Mazin Diwan , Almayah Abdulamir Atalla 
Published: February 2023

Built-up steel girders have many applications in structural engineering, both in bridges and buildings. Flat web steel girders, which are the traditional choice, involve several weaknesses. Girders with corrugated webs were found to be more effective in their load-carrying capacity and deflection than girders with flat webs. In light of this, an effort is made in this work to examine how the addition of triangular corrugated webs influences the load-bearing capacity and deflection of steel girders. This study aimed to determine whether or not the strength of built-up steel with corrugated webs could be improved. A concentrated midspan load was applied to six simply supported steel beams of varying span-to-depth ratios (1.0, 1.833, and 2.5) and web corrugation amplitudes (30 and 60 mm). An increase in ultimate strength of 15.7% to 35.1% was found for webs with triangular corrugations of 30 mm and from 2% to 29.1% for webs with corrugations of 60 mm. A reduction in deflection of up to 35.3% can be attained when using triangular corrugated webs. It was also found that using webs with 30 mm corrugations was more efficient than using webs with 60 mm corrugations. The effect of corrugation was found to fade when the span-to-depth ratio increased to 2.5. This led to the conclusion that using webs of 30 mm amplitude of triangular corrugation could improve the strength and serviceability of steel girders. Doi: 10.28991/CEJ-2023-09-02-09 Full Text: PDF

özellikleri ortaya koyarak onu yüceltmektir. Bu durum Elvan Çelebi’nin yazdığı Menâkıbu’l-Kudsiyye (14. yy) ile Halil bin İsmail’in yazdığı Sımavna Kadısıoğlu Şeyh Bedreddin ve Manâkıbı (15. yy) için de geçerlidir. Menâkıbu’l-Kudsiyye’de Babai isyanı, Elvan Çelebi’nin dedesi ve aynı zamanda isyanın lideri olarak bilinen Baba İlyas konu edinilmiştir. Eserde ayrıca Baba İlyas’ın oğullarının da hayat hikâyeleri ve menkıbeleri anlatılmıştır. Şeyh Bedreddin ve Manâkıbı’nda da aynı şekilde Halil bin İsmail’in dedesi olan Şeyh Bedreddin, Şeyh’in çocukları ve silsilesi, ayrıca ona isnat edilen ayaklanma hakkında bilgiler verilmiştir.
Menâkıbu’l-Kudsiyye’nin ile Şeyh Bedreddin ve Manâkıbı’nın konu edinilen kişilerin torunları tarafından yazılmış olmaları bu yazının çıkış noktasını oluşturmaktadır. Her iki eserde de resmî tarih anlayışı çerçevesinde “isyancı” olarak tanımlanan Baba İlyas ve Şeyh Bedreddin, merkeze alınarak olaylar anlatılmış, torunları tarafından aklanmaya çalışılmış; dedeleri hakkında söylenen iddiaların iftira ve yalandan ibaret olduğu iddiası ilginç bir şekilde, birbirine benzeyen yapısal özellikler içerisinde ortak menkıbevi unsurlar ve motiflerle süslenerek işlenmiştir. Bu durum; klasik bir menakıpnamede görülen ele alınan veliyi övme ve onun kutsiyetini abartarak anlatma amacının dışına çıkarak bu eserleri birer savunma metni haline getirmiştir. Bu çalışmada söz konusu iki eser karşılaştırmalı biçimde incelenmiş, aynı amaçla yazılmış olmalarının zemin hazırladığı benzerlikler ortaya koyulmaya çalışılmıştır.
PERFORMANCE INVESTIGATION OF WIND TURBINES BASED ON DOUBLY FED INDUCTION GENERATORS WITH BACK-TO-BACK CONVERTER
Authors: Alyousuf Abdullah Muwafaq , Korkmaz Fatih 
Published: February 2023

In the last decades, wind turbines have been extensively studied due to the increasing demand for renewable energy sources. Based on a very strong background of operational experience with wind turbine generators of varying sizes and the development of high-performance power electronics, these most recent wind turbine generators offer the requisite and enhanced performance for their safe integration into the power systems. In the past, wind turbine generators were simply connected to distribution networks; however, current projects and wind turbine generators sizes require a direct connection to the transmission system level through a project-specific substation. Due to these developments, an integrated strategy is needed to maximize the allocation of control responsibilities between substation control and wind turbine control. Dual-Fed Induction Generator (DFIG) systems can be used in many ways to make complex solutions. In this paper, the design and control of DFIG systems are presented to improve WT operating performance in different cases. Given the strong association between converter control strategies and working conditions, it is important to better understand to demonstrates the importance of developing an appropriate modelling approach. The key findings are discussed, and recommendations are provided for future research in this paper.

Food Intolerance and Sensitivity Are Associated With Chronic Musculoskeletal Pain in a Self-Selected Community Population
Authors: Thomson Ella , Beer Harriet , Ryan Laura , Philcox Edward , Kelly Clive 
Published: February 2023

INTRODUCTION People are presenting with chronic musculoskeletal pain at a younger age, and many fulfil criteria for fibromyalgia. We have recently shown a strong association between fibromyalgia symptoms and autistic traits in a self-selected community population, with the relationship mediated in part by the presence of hypermobility. Many respondents also described food sensitivities and intolerances. This study explores the relationships between food issues and fibromyalgia symptoms in this population. METHODS The study used a nonexperimental, correlational design with data collected from a volunteer sample of 442 adults (aged 18-60) who completed online self-report questionnaires assessing each of fibromyalgia symptoms (ACR criteria), autistic traits (RAADS score) and hypermobility (Beighton’s test). Subjects were also asked to record any food sensitivities, allergies, or intolerances, along with their consequences. Correlation analyses and linear regressions were used to test the relationships between these features and each of fibromyalgia, autistic traits and hypermobility. Data was analysed using parametric and non-parametric techniques to assess the strength and significance of relationships, and the potential mediating effect of food-related symptoms in the correlation between fibromyalgia features and autistic traits. RESULTS Our self-selected community population had a mean age of 24 years and was 77% female. The prevalence of fibromyalgia, autistic traits and hypermobility was 40%, 65% and 44% respectively. Half of all subjects reported food sensitivity and 31% reported food intolerance. The incidence of food-related symptoms was higher among subjects who met criteria for fibromyalgia than those who reported autistic traits or hypermobility. Food sensitivity and food intolerance were both more significantly associated with fibromyalgia (r=0.24, p<0.001 and r=0.38, p<0.001) than with autistic traits (r=0.15, p<0.01 and r=0.17, p<0.01). DISCUSSION This is the first community study to provide evidence for a direct association between features of fibromyalgia and reported food intolerance and sensitivity. Although self-selected, the findings in our predominantly young population suggest that gluten and lactose consumption may be associated with higher levels of musculoskeletal pain. The study population commonly reported that avoidance of gluten and / or lactose containing foods reduced symptoms. Dietary adjustment may merit further investigation as a therapeutic modality for some patients with fibromyalgia.

A quasi-experimental study was conducted at Radiation Oncology Department of National Institute of Cancer Research & Hospital (NICRH), Dhaka, Bangladesh, between November 2020 and October 2021, to determine the efficacy of cryotherapy in comparison to standard oral care to prevent oral mucositis in head and neck cancer patients during receiving CCRT. A total 100 Patients (50 patients in each arm) were included in this study according to inclusion and exclusion criteria by purposive sampling technique. All patients in Arm A and Arm B received total 66 Gray in 33 daily fractions, 1 fraction per day, 5 fractions per week and inj. Cisplatin 40mg/m² was given intravenously 2/3 hours before radiotherapy on 1st day and then weekly. Arm A received cryotherapy and Arm B received standard oral care. Intervention started from the 1st day of CCRT up to the end of CCRT. WHO oral mucositis grading and visual analogue scale (VAS) were employed to determine the effects. All the information was recorded in a pre-tested semi-structured questionnaire. Total 100 patients (50 patients in each arm) were enrolled. Mean age of the patients of Arm A and Arm B was 55.28±7.82 and 55.92±8.33 respectively. Male and female ratio was 6.14:1 in two Arms. Other demographic profile, baseline characteristics were statistically not significant in both arms (P>0.05). The grade-3 mucositis appeared after 5th week in Arm B and after 6th week in Arm A. The incidence of grade- 3 mucositis after 5th week during CCRT to 4 weeks after completion of therapy was 6% vs 0%, 14% vs 6%, 22% vs 10%, 14% vs 6%, 8% vs 2%, respectively for arm B and Arm A (P<0.05). Total number of patients suffering from grade 3 mucositis was 6 (12%) and 12 (24%) for Arm A and Arm B respectively (p value was <0.05). The mean duration of grade-3 or more mucositis between Arm A and Arm B was 2.04±1.78 and 10±1.72 days respectively (P<0.05). The difference of median pain intensity between two arms was not statistically significant for 1st and 2nd week (P>0.05). However, it was significant after 3rd week during CCRT to 4 weeks after completion of CCRT (P<0.05). Cryotherapy during CCRT may be beneficial to prevent oral mucositis and pain than maintaining standard oral care.

Published: February 2023

The scapula is a complex anatomical unit; it connects the humerus with the clavicle. The scapula presents several variations, based on race, sex and region. Sexual dimorphism plays a key role in forensic anthropology. The scapula is sexually dimorphic and can potentially be used in forensic investigations. A cross-sectional study was conducted under Department of Anatomy, Dhaka Medical College, Dhaka, between July 2017 and June 2018, to observe the morphometric pattern of the left scapula in adult male and female Bangladeshi people for establishment of a baseline anatomical data for future studies. Shoulder radiograph of anterior-posterior view were taken from 100 apparently healthy adult male and female patients aged between 25 and 50 years who were attending the Department of Radiology & Imaging, Dhaka Medical College Hospital, Dhaka. From these images morphological measurements like the length and breadth of left scapula, the lengths of infraspinous line and scapular spine were measured by software named RadiAnt DICOM Viewer. The length and breadth of left scapula, the length of coracoid process, as well as the lengths of infraspinous line and scapular spine were found significantly higher in males. To summarize, a significant difference was observed in morphological measurements of the left scapula between the sexes in Bangladeshi people.

Study on the Effect of Topical Pre-operative Nonsteroidal Anti-inflammatory Drugs in Maintaining Mydriasis during Small Incision Cataract Surgery
Authors: Hussain Md Emdad 
Published: February 2023

A prospective, randomized, double masked, single centered comparative study done in the Bangladesh Naval Ship Patenga, Chattogram, Bangladesh, from July 2021 to June 2022, to assess the clinical benefits and effectiveness of prophylactic pre-operative topical administration of NSAIDs in maintaining mydriasis during small incision cataract surgery. Thirty patients underwent small incision cataract surgery with intra ocular lens implantation were randomized to compare the efficacy of topical NSAIDs drops (Group-A) and placebo drops (Group-B) in maintaining peroperative mydriasis. Balanced salt solution containing non preservative adrenaline was used in all patients. Pupil size was measured prior to the corneal incision and after the completion of the operation. The two groups were analyzed with respect to the changes in pupillary diameter at the beginning and at the end of the operation. The change in pupil size was significantly different among the two groups at the end of the surgery. The mean vertical and horizontal diameter of the two groups were near about similar at the beginning of the surgery. Significant differences were seen after IOL implantation with the NSAIDs group having the larger mean diameter in both vertical (P=0.003) and horizontal (P=0.008) pupillary measurements at the conclusion of surgery. Topical NSAIDs has been shown to be a more effective inhibitor of meiosis during per operative uncomplicated small incision cataract surgery and provides a more stable mydriatic effect during surgery compared to the placebo group.
