Chaboche Model for Fatigue by Ratcheting Phenomena of Austenitic Stainless Steel under Biaxial Sinusoidal Loading
Authors: Boussalih Fatiha , Fedaoui Kamel , Zarza Tahar 
Published: March 2022

This study deals with the investigation of the cyclic behaviour of 316L and 304L austenitic stainless steels in oligocyclic fatigue under biaxial loading. As a first step, we investigated the prediction of the character of 316L steel under imposed stress, by the fixation of a stress and the evolution of another, forming a cross-proportional loading path in a range of stresses. In addition, the analysis of the behavior of steel 304L with respect to the bi-axial union (primary and secondary loadings) was studied in order to produce the ratcheting phenomenon induced by the non-zero mean stress, governing the structure to damage in two opposite directions, diagonally symmetrical. An appreciable confrontation of the intrinsic characters of the two steels under the same loading conditions was discussed in the last intervention, controlled in strain, generating the phenomenon of cross-hardening and imposed stress. Producing the progressive strain that manifests itself at each loading cycle will make it possible to quantify the degree of plasticity of each material and optimize the most relevant steel. In this numerical study, the Chaboche model is selected, which is based mainly on perfect predictions and robust constitutive laws capable of reproducing observed macroscopic phenomena. All the simulations were carried out using the ZéBulon computation code. A lot of work on the behavior of 304L and 316L stainless steel has been carried out by several researchers in recent years. The results of previous experiments and numerical simulations have been compared to the results of this study, and a good match has been found.

Published: March 2022

In this research, the structural behavior of reinforced concrete brackets cast with concrete containing different types of fibers was studied. Seven samples of reinforced concrete corbels were cast and tested. One specimen was cast without fiber as a reference, and the other samples were made with six different types of fibers at a constant volume fraction (1% of the total concrete volume). The fibers used in the research were made of two different materials: steel and polyolefin. One specimen was cast with polyolefin fiber, and in the five remaining samples, steel fiber was used. Straight, crimped, and three different dimensions of hooked fiber were used. The results showed that the corbels with straight and hooked end steel fiber (6, 5, and 3 cm length), crimped steel fiber sized 3 cm, straight steel fiber sized 12 mm, and straight polyolefin fiber sized 6 cm showed 69.2%, 57.7%, 38.5%, 61.5%, 92.3%, and 100% higher cracking loads than the control corbel made with normal concrete, respectively, as well as exhibiting (51.7%, 48.3%, 31.0%, 24.1%, 12.1%, and 3.4%) higher ultimate loads than the control corbel. From these results, it can be concluded that the shape of the steel fiber clearly affects the ultimate load. For the same length, and despite the lack of aspect ratio, steel fibers gave an increase in the maximum load of 46.6% when compared with polyolefin fibers.

Forbidden Words: Language Control and Victorian Political Correctness in Dickens and Carroll
Authors: Benziman Galia 
Published: March 2022

This article examines Charles Dickens’s and Lewis Carroll’s representations of mechanisms of control over people’s – especially young people’s – language, imagination, and minds. Moralistic on the one hand, political on the other hand, Victorian patterns of censorship and self-censorship are reflected, critiqued, and satirised by Dickens in various stages of his career, and are related in his work to artistic creativity, language and the imagination. He attacks the utilitarian resistance to fairy tale and especially Maria Edgeworth’s manifesto on the usefulness and uselessness of various genres of children’s literature, and criticizes George Cruikshank’s revisionist project of furthering certain social doctrines, mainly teetotalism, by interpolating moralistic messages into famous fairy tales. Much of this preoccupation is followed up in Carroll’s Alice books. For both, I argue, these didactic revisions are related to patterns of language control, banned words, and euphemisms that they repeatedly probe and parody in their fiction. My essay will examine the representation of language control, self-censorship and verbal training in terms of an early, Victorian-era politically-correct discourse; I will ask what, if at all, Dickens and Carroll’s treatment of these issues may contribute to the current debate surrounding our own politically-correct culture.

Authors: Shali Kochuvelickakathu Sivan , Soumya Neelakanta Pillai Padmakumari , Mondal Sukanta , Mini Saraswathy 
Published: March 2022

Background: Diabetes mellitus is widely recognized as one of the leading causes of death and disability worldwide. Hyperglycaemia-mediated oxidative stress plays a significant role in the development and progression of diabetes - induced liver damage.Objective: The main aim of the study was to explore the modulatory effect of the flavonoid morin (3,5,7,2’,4’ -pentahydroxyflavone) on oxidative stress and carbohydrate metabolism in the liver of streptozotocin (STZ) induced diabetic rats.Methods: Diabetes was induced in male albino rats by intraperitoneal injection of streptozotocin (40 mg/kg body weight) and subsequently, the animals were given morin intragastrically at a dose of 50 mg/kg body weight for 60 consecutive days. At the end of the treatment period, the animals were sacrificed by an intraperitoneal injection of thiopentone sodium. Blood and liver tissue were collected for further biochemical evaluation and the effects were compared with diabetic rats administered metformin, a standard antidiabetic drug.Results: Elevated blood glucose and HbA1c levels in diabetic rats were significantly decreased by morin administration. Morin effectively modulated the alternations in the concentration of lipid peroxidation products, activities of antioxidant enzymes and carbohydrate metabolizing enzymes in the liver of diabetic rats. The overall effects were comparable with diabetic rats administered with metformin.Conclusion: The results of our study proved that the morin administration exerts hepatoprotective activity by decreasing oxidative stress and regulating the altered activities of carbohydrate metabolizing enzymes in diabetes.Keywords: diabetes, morin, liver, oxidative stress, carbohydrate metabolism
Risk factors for chronic kidney disease progression in patients with solitary kidney
Authors: KARAER BÜBERCİ Refika , DURANAY Murat 
Published: March 2022

Introduction: The prevalence of chronic kidney disease (CKD) is rapidly increasing worldwide. Solitary kidney is also increasing in ranking among the CKD etiologies, because there has been a rapid increase in the number of radical nephrectomies due to an increased number of renal transplantations from live donors and an increased number of patients with renal cell carcinoma. The aim of the current study is to identify risk factors that affect the glomerular filtration rate (GFR) in individuals with solitary kidney.
Material and Method: The current study included 204 patients (75 with congenital, 129 with acquired solitary kidney). Laboratory data during the first and last admissions were recorded. Patients divided into two groups according to annual decline of eGFR. Group I and II consisted of patients whose annual decline eGFR was more than 1ml/min/1.73 m2 and less than 1ml/min/1.73 m2, respectively. In addition, patients were divided into two groups as patients with congenital and acquired solitary kidney. The first control is the first examination in the nephrology outpatient clinic for congenital solitary kidney patient and the post-operative examination on the fourteenth day after discharge from the hospital for the acquired solitary kidney patient. The final control is the examination within the last three months before reaching the primary endpoint of the study.
Results: Of the patients, 36.8% were male, and the average age was 57.16±15.04 years. The duration of the follow-up period was 6.48±3.69 years. Group I had higher rates of diabetes mellitus, cardiovascular disease, older age, higher mean blood pressure(MBP), glucose, CRP, total cholesterol (TC), LDL-cholesterol, non-HDL-cholesterol, triglyceride/non-HDL-cholesterol ratio and lower albumin. In the group with acquired solitary kidney, the patients were older, the incidence of cardiovascular diseases was higher, and the eGFR at the first and last admission was lower. There was no difference between acquired SK and congenital SK in terms of annual change in eGFR. In regression analysis CRP, LDL-cholesterol, non-HDL-cholesterol, TG/non-HDL-cholesterol ratio are independent risk factors on annual decline of eGFR. Having a congenital or acquired single kidney had no effect on the annual decline of eGFR. In addition, TC, TC/HDL-cholesterol, triglyceride/non-HDL-cholesterol, triglyceride/HDL-cholesterol ratios, non-HDL -cholesterol correlated with CRP positively.
Conclusıon:Patients with solitary kidney have higher risk of developing CKD. Inflammation and dyslipidemia must be paid attention to protect eGFR. Besides the atherosclerosis in the microcirculation, dyslipidemia affect eGFR through inflammation. Having a congenital or acquired single kidney has no effect on the annual decline of eGFR.

Published: March 2022

Aim: The aim of the study is to determine the frequency of first-trimester thyroid dysfunction in pregnant women and to investigate the effect of thyroid dysfunction on some perinatal outcomes.
Material and Method: In the study, first-trimester Thyroid stimulating hormone (TSH), free T4 and free T3 hormone values of pregnant women who applied to our outpatient clinic were retrospectively scanned and recorded. As a result, 3224 pregnant women were included in the study. Pregnant women were evaluated as overt hypothyroidism, subclinical hypothyroidism, overt hyperthyroidism, subclinical hyperthyroidism and euthyroid according to TSH and fT4 values. Results of thyroid function tests of pregnant women and some perinatal results (age, gestational week, delivery type, baby gender, birth weight, gravida, parity, abortion) were compared
Results: In our study, the mean age of the pregnant women for screening was 28.6±3.1, the mean birth week was 38.7±2.1, and the mean birth weight was 3037±324.73.6% (n=2369) of the pregnant women were normal euthyroid, 0.71% (n=23) were subclinical hyperthyroidism, 0.65% (n=23) were overt hyperthyroidism, while 15.6% (n=507) were overtly hypothyroid and 9.4% 3 (n=304) were found to be subclinical hypothyroidism. A significant statistical difference was not found between thyroid outcome test results and perinatal outcomes (age, gravida, parity, abortion, birth strength, gestational age, delivery type, babies) (p> 0.05).
Conclusion: In our study, a high prevalence of thyroid disease, especially hypothyroidism, was observed in pregnant women. More studies should be done to evaluate the effect of thyroid functions on pregnancy outcomes.
